fix(mosaic): de-flake mutator-class lease gate TTL-expiry test (#861)

Bound broker reply deadlines (separate read/lock/send budgets, BROKER_BUSY-before-mutation, fresh post-handle send budget → closes drop-after-commit window); fail-close empty/truncated read → GATE_UNAVAILABLE deny. De-flakes the 1917 acceptance surface. terra CODE APPROVE (pi) + Opus SECREV APPROVED (claude) — RoR comment 18143. Promote-lease-lost-ACK residual = fail-safe two-generals observability-gap, routed to WI-3 D2-v5 as named-disclosed-bounded-residual (route i). Gate-16 3-principal author=gpt-sol.

+## Compaction Refresh Trust Lifecycle (M1, #827–#830)
+
+### Problem and objective
+
+Context compaction, session replacement, and same-PID runtime reloads can leave a previously VERIFIED runtime lease attached to stale directives. M1 must revoke that authority mechanically for Claude (including Claudex) and Pi without trusting caller-asserted identity or forking the external broker state machine.
+
+### Requirements
+
+1. `CR-REQ-01`: Claude `PreCompact` and `SessionStart` with matcher `compact`, plus Pi `session_before_compact` and the first post-`session_compact` `context`, SHALL independently revoke the active broker lease.
+2. `CR-REQ-02`: Runtime generation increases—including same-PID Pi reload/new/resume/fork and Claude resume/clear—SHALL monotonically replace the prior broker incarnation and inherit no VERIFIED lease.
+3. `CR-REQ-03`: A fired observer that cannot confirm broker revocation SHALL fail closed through lifecycle cancellation, a private local generation fence, and/or a runtime-local tool latch. The existing all-tools broker gate remains authoritative.
+4. `CR-REQ-04`: The lease TTL SHALL remain monotonic and capped at 300 seconds. If both observers are missed, within-TTL consequential actions remain allowed and after-TTL actions are denied. This named bounded residual stale window SHALL be documented without claiming a mutator-action bound inside the window.
+5. `CR-REQ-05`: Hook descendants SHALL use the broker-minted session and owner-only current-generation state inherited from register-before-exec. Caller-minted sessions and parallel lease state machines remain forbidden.
+
+### Acceptance criteria
+
+1. `AC-CR-01`: Real-socket tests prove each Claude observer revokes, Pi lifecycle tests prove both observer paths, and Claudex isolated settings preserve and install the mandatory hooks.
+2. `AC-CR-02`: A same-PID generation test proves the old generation is stale and the replacement generation is UNVERIFIED across reload/resume/fork-equivalent lifecycle events.
+3. `AC-CR-03`: RED-first T12b/T30 evidence explicitly reports dual-hook miss within TTL as **ALLOWED** and after TTL as **DENIED**.
+4. `AC-CR-04`: Attributable executable coverage is at least 85%, the full repository suite is green on deterministic main, and independent code/security review completes before merge.

+# Compaction observer revocation and runtime generations
+
+WI-3 connects Claude and Pi compaction/session lifecycle events to the existing authenticated lease-broker state machine. It does not add a second lease store or let runtime hooks assert identity. Each observer inherits the broker-minted session, resolves the current private runtime generation, and sends the existing `revoke_lease` action over the authenticated Unix socket.
+
+## Observer matrix
+
+| Runtime          | Lifecycle signal                                                 | Action                                                                                                                       |
+| ---------------- | ---------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------- |
+| Claude / Claudex | `PreCompact`                                                     | Revoke the current lease before compaction. A non-zero hook result blocks the lifecycle transition.                          |
+| Claude / Claudex | `SessionStart` with matcher `compact`                            | Revoke again after compacted context starts.                                                                                 |
+| Claude / Claudex | `SessionStart` with matcher `resume\|clear`                      | Atomically advance the private generation, then revoke the replacement incarnation.                                          |
+| Pi               | `session_before_compact`                                         | Revoke before compaction; return `{ cancel: true }` if revocation cannot be confirmed.                                       |
+| Pi               | `session_compact` then the first `context`                       | Arm and run an independent post-compaction revoke. A failed post observer blocks later tools locally until a retry succeeds. |
+| Pi               | `session_start` with reason `reload`, `new`, `resume`, or `fork` | Atomically advance the private generation, then revoke the replacement incarnation before reuse.                             |
+
+The first observer that reaches the broker deletes pending promotion tokens and makes the lease `UNVERIFIED`. The second compaction observer is deliberate redundancy, not a prerequisite for the first. Claudex receives the same mandatory hooks in its isolated `CLAUDE_CONFIG_DIR`; hook merging preserves unrelated isolated settings and rejects malformed or symlinked settings fail-closed.
+
+## Private generation authority
+
+`launch-runtime.py` still registers before `exec`, preserving the kernel-authenticated PID/starttime anchor. It now also creates `generation-<broker-session>.state` beside the broker socket. The file is owner-only mode `0600` under the broker's mode-`0700` directory. Hook descendants read that file instead of relying only on an immutable inherited environment value.
+
+Generation changes use an exclusive file lock, validate owner/type/mode/size, increment monotonically, truncate and write the complete new value, and `fsync` before contacting the broker. Therefore reload, new-session, resume, and fork events may retain the same PID/starttime while still becoming a new broker incarnation. The higher generation causes the broker to atomically discard prior tokens and lease authority; the replacement generation inherits no VERIFIED lease.
+
+If an observer fires while broker transport is unavailable, `revoke-lease.py` advances the private generation as a local fence before returning non-zero. Every later all-tools gate reads that higher value. When the broker is reachable again, authentication of that value performs the same old-generation revocation before authorization. Pi also keeps a process-local post-compaction/rollover failure latch that blocks tool calls. An unsafe or unreadable generation file itself makes both lifecycle revocation and tool authorization fail closed.
+
+## Threat contract and stopping boundary
+
+### BOUNDED RESIDUAL STALE WINDOW
+
+If **both** pre- and post-compaction observers are missed entirely, no revocation signal exists. During the remaining unexpired lease, **within-TTL consequential actions are allowed**. Their count and timing are **bounded by lease expiry, not by the mutator gate**. WI-3 makes no claim that it bounds mutator actions inside this stale interval. The broker's monotonic lease TTL is capped at 300 seconds; after expiry, the next consequential tool is denied with `LEASE_EXPIRED`.
+
+This is the named D2-v5 T-A residual. It is distinct from an observer that fires but cannot contact the broker: the latter creates a local generation fence and fails closed. It is also distinct from T-C total rot, where the lifecycle observers and the all-tools gate are both absent or replaced. Server-side branch protection, required CI, and independent review remain the irreducible backstop for T-C.
+
+| Condition                                                       | Result                                                                                                                |

+| Observer runs but broker confirmation fails                     | Lifecycle transition is denied where supported; local generation fence and runtime latch prevent inherited authority. |

+
+## T-C server-side branch-protection posture
+
+The required posture is that `main` is push-blocked and PR-only-merge is **MANDATORY**, regardless
+of client-gate state. The client-side gate narrows the exposure window only; it is not the T-C
+guarantee. The server-side protected-branch configuration is the irreducible guarantee for protected
+repository actions. Status-check enforcement and approval enforcement are **RECOMMENDED**.
+
+## Current-vs-required gap (recorded, not enacted)
+
+The current empirical configuration is recorded here without re-probing or mutating live branch
+protection. `enable_push=False` (push-block present), so the mandatory push-block/PR-only-merge core
+holds. `require_approvals=0` (approvals not enforced), `enable_status_check=False` (status checks not
+enforced), and `block_on_official_review=False` (official review not enforced). Those recommended
+merge-quality controls are the current gap; changing them is a separate, owner-gated operations
+decision and is not enacted by this documentation change.
+
+The permanent T12b/T30 acceptance case prints both required outcomes: dual-hook miss within TTL is **ALLOWED**, and the same lease after TTL is **DENIED**. Separate real-socket tests prove each Claude observer and same-PID generation rollover; Pi lifecycle tests exercise pre/post observers, all four replacement reasons, and local failure closure.

+# Authenticated external lease broker protocol
+
+The compaction-refresh lease broker is a Linux-only, newline-framed JSON protocol over a Unix stream socket. It is runtime-neutral; M1 consumers are limited to Claude and Pi. This is an internal process boundary, not an HTTP API, so it is intentionally absent from OpenAPI.
+
+The broker, never the caller, obtains `(pid, uid, gid)` from kernel `SO_PEERCRED`. It correlates the PID with `/proc/<pid>/stat` field 22 (`starttime`) and mints `session_id` on `register_anchor`. Presence of `session_id` in that request is refused even when its value is `null` or empty. Later requests must originate from the anchor or a descendant. The broker walks parent PIDs to the `(pid,starttime)` anchor and then rereads every walked PID's starttime before accepting the chain.
+
+## Request and response boundary
+
+Each connection carries exactly one UTF-8 JSON object followed by one newline, capped at 64 KiB. The protocol deliberately uses EOF to prove that there is exactly one frame: immediately after writing the newline, the client **MUST half-close its write side** with `shutdown(SHUT_WR)` (or Node `socket.end()`) before awaiting the response. A client that writes a newline but leaves its write side open receives no successful response; the broker's one-second connection deadline fails closed. Malformed, unterminated, multiple (including a delayed second frame), or oversized frames fail closed. Responses are one JSON object and one newline. Success has `{"ok":true,...}`; refusal has `{"ok":false,"code":"TYPED_CODE"}`. Requests are:
+
+- `register_anchor`: `action`, non-negative `runtime_generation`; no `session_id` field.
+- `authenticate`: `action`, broker-minted `session_id`, non-negative `runtime_generation`.
+- `mint_token`: authenticated identity plus `binding` containing exactly `compaction_epoch`, `request_epoch`, `h_source`, `h_payload`, and `schema_version`.
+- `consume_token`: authenticated identity plus `token`.
+- `begin_verification`: authenticated identity, runtime (`claude` or `pi`), cycle `binding`, and a TTL no greater than 300 seconds. The broker revokes existing authority first, enters `PENDING_VERIFICATION`, and returns a single-use promotion token.
+- `begin_recovery`: the constrained recovery entrypoint. It rejects caller-provided receipt/challenge fields and delegates to the same `begin_verification` transition, but reports `PENDING_DELIVERY` and marks the volatile cycle as recovery-owned.
+- `complete_recovery`: authenticated identity only. It rejects caller-provided receipt/challenge fields, obtains the current recovery challenge only from broker state, and delegates to the same trusted-observer → evidence → consume → promote sequence. An observation failure revokes recovery authority; retry starts a fresh challenge.
+
+The daemon owns a second protected production observer socket (mode `0600`) unless a private `--test-observer-file` fixture is selected. That transport accepts only the exact `record_runtime_observation` schema after kernel `SO_PEERCRED` plus the existing anchor/ancestry authentication; it validates the pending runtime/generation before storing one finalized assistant entry for the in-process `RuntimeReceiptObserver`. It is **not** a broker request action. Claude sends its latest assistant entry from the Stop-hook transport; Pi sends only finalized `message_end` assistant content. The public broker socket continues to reject request-supplied `latest_assistant_message` in begin, observe, and complete paths.
+
+- `promote_lease`: authenticated identity plus the exact pending promotion token. The broker commits token consumption before making `VERIFIED` visible.
+- `revoke_lease`: authenticated observer signal; deletes pending tokens and makes the session `UNVERIFIED` immediately. WI-3 Claude/Pi hooks send this existing action; `runtime` and bounded `reason` fields are diagnostic input only and never identity authority.
+- `authorize_tool`: authenticated identity, runtime, and exact runtime-reported tool name. The broker returns an explicit allow/deny decision from the whole-class policy and current lease.
+
+A higher generation for the same anchor atomically replaces the stored incarnation and deletes all prior tokens and lease authority for that session. A lower generation is stale. Runtime descendants resolve the current generation from an owner-only, locked generation file created by the register-before-exec launcher; reload/new/resume/fork observers advance and `fsync` it before broker revocation. This supports generation replacement even when PID/starttime do not change. Tokens are 256-bit values from the operating-system cryptographic RNG and are single use. At most 256 pending tokens may be persisted; another mint fails with `TOKEN_CAPACITY` before mutation. Successful consumption deletes the token, while a replay still fails with `TOKEN_REPLAY`. Live v1 token records retain the existing `consumed: false` schema.
+
+VERIFIED leases are volatile and monotonic-time bounded: broker restart, generation change, explicit observer revocation, or expiry returns the session to `UNVERIFIED`. `begin_verification` always revokes before minting a new prerequisite. `begin_recovery` reuses that exact transition and mints a new challenge, so a normal-path receipt/challenge cannot be replayed through recovery. `promote_lease` is valid only from the matching pending cycle; persistence failure rolls token and lease state back, while post-rename durability uncertainty terminates the broker. The WI-1 token is the atomic promotion prerequisite substrate.
+
+## Receipt boundary and T-C residual (R1)
+
+Receipt evidence is a T-A delivery/liveness prerequisite only; it cannot replace the mechanical
+mutator gate as safety authority. The receipt detects an **ABSENT** or **PREFIX-TRUNCATED** terminal
+token. A **MIDDLE-DROP** that preserves the tail is a T-C contract violation that is **NOT receipt-detectable**. It is covered by server-side protected-branch controls, **NOT** by the receipt; no category-wide receipt-detection claim is made for that tail-preserving transformation.
+
+State replacement serializes and enforces the 4 MiB maximum before opening a temporary file, then uses a mode-`0600` temporary file, `fsync`, atomic rename, and parent-directory `fsync`. Every broker mutation snapshots the prior v1 state. A commit failure before rename restores that snapshot and leaves durable state unchanged. A failure after rename makes durability uncertain, so the store is poisoned without rolling memory back and the daemon terminates rather than serving with divergent state. Existing state is opened without following symlinks, must be a bounded regular file at mode `0600`, and is fully schema- and invariant-validated before use. Persisted tokens must be unconsumed, match their session's current generation, and remain within the 256-token cap. Session identity is uniquely keyed by `(anchor_pid,anchor_starttime)`; duplicate logical sessions for one anchor refuse startup. State integrity or mode failures refuse startup. The daemon does not log session IDs or tokens.

+# WI-1 lease broker security notes
+
+- Trusted identity comes only from Linux `SO_PEERCRED` plus `/proc` starttime, never request identity fields.
+- Descendant authorization is anchored to `(pid,starttime)` and uses a complete second starttime pass to fail closed on disappearance or PID-reuse races.
+- Runtime generations are monotonic per anchor; a bump revokes prior-incarnation tokens before persistence commits. WI-3 stores the live generation in an owner-only locked file so same-PID Pi reload/new/resume/fork and Claude resume/clear transitions cannot inherit a VERIFIED lease.
+- Session IDs and cycle tokens use the OS cryptographic RNG. `Math.random` and model output are not token sources.
+- Framing and persistence failures fail closed. Sensitive tokens are not logged.
+- Built-in `0700`/`0600` filesystem modes provide same-principal hardening only, not socket authenticity against the same UID. WI-1 provides no distinct-principal isolation. That stronger deployment requires an external protected proxy, ACL, or service boundary, and the boundary must preserve authenticated client identity for the broker's `SO_PEERCRED` and ancestry authorization rather than substituting a shared proxy identity.
+- WI-2 whole-class authorization denies every consequential, unknown, and custom tool while UNVERIFIED; it does not inspect shell strings or trust wrapper selection. First-class Claude/Pi, both Claudex dispatch modes, PRDY, QA remediation, coord, orchestrator, and fleet starts converge on broker register-before-exec; Claudex additionally installs the mandatory all-tools hook inside its preserved isolated config and fails closed on unsafe settings.
+- The permanent `check-runtime-launches.py` suite/CI guard scans production source for direct literal, absolute-path, process-API, command-array, and dynamic Claude/Pi launches. It has no bypass allowlist: an unrecognized launch form fails CI until routed through the common boundary.
+- WI-2 promotion consumes a WI-1 cycle token before VERIFIED becomes visible. Observer revocation, runtime-generation replacement, broker restart, and monotonic TTL expiry remove authority.
+- WI-3 wires redundant Claude `PreCompact`/`SessionStart(compact)` and Pi `session_before_compact`/post-`session_compact` `context` observers to that same revoke action. If broker confirmation fails after an observer fires, the revoker advances the private generation as a local fence; subsequent authorization revokes the stale broker incarnation before any consequential allow.
+- Dual observer absence while a lease remains live is the named **bounded residual stale window**: consequential tools remain allowed until monotonic expiry, with no claimed within-window action bound. After expiry they are denied. Total observer-plus-gate absence remains T-C.
+- Receipt observation, payload construction, and constrained recovery implementation remain later surfaces. A receipt can become a promotion prerequisite but is never the safety mechanism.
+
+## Named residual: promote-lease-lost-ACK (WI-3 D2-v5)
+
+A valid `promote_lease` can leave a session `VERIFIED` in the broker while the client never learns of it. This is a named, bounded D2-v5 T-A residual — an **authority-observability divergence, not an authority divergence, not an ALLOW-risk, and not a retry double-apply**. It is disclosed here, not laundered.
+
+**Window — where it can occur.** The broker commits token consumption and durable `VERIFIED` state _before_ the success reply becomes visible (see the promotion order in `lease-broker-protocol.md`). The residual is confined to the interval after that commit+fsync when the broker→client reply or peer-ACK is lost — for example an extreme-contention send failure or peer disconnect after `handle()` has already mutated and persisted state (the #838 fail-closed transport path). The lease mutation is already durable broker-side; only the acknowledgement to the client is lost. No uncommitted or partially-applied state is involved: the commit either happened (and is authoritative) or it did not (and no lease exists).
+
+**Fail-safe direction — the client can only under-claim.** Broker intent is the ceiling; client authority is always ≤ broker intent, never more. Client-side authority-belief is granted only by a _received_ acknowledgement; a lost acknowledgement conveys nothing, so the client cannot conclude "verified" and continues to treat itself as `UNVERIFIED` (it re-verifies or recovers). If the client retries `promote_lease` with the same token, the token is already consumed and the broker rejects the retry (`PROMOTION_TOKEN_MISMATCH` / `INVALID_LEASE_TRANSITION`); there is no double-apply. The committed `VERIFIED` state the broker holds is authority the lease _legitimately earned_ from a real promotion — the broker authorizing consequential tools under it is correct, not inflation. Divergence is therefore strictly toward _less_ client authority than the broker granted; it never produces authority the broker did not grant.
+
+**Bound — TTL plus the observer/gen-bump revoke backstop, self-healing.** The orphaned `VERIFIED` lease is indistinguishable to the broker from any other legitimately verified lease, so the identical D2-v5 revocation backstops dispose of it: any compaction observer (`PreCompact` / `SessionStart(compact)` for Claude; `session_before_compact` / post-`session_compact` `context` for Pi), any same-PID runtime-generation bump (reload/new/resume/fork), broker restart, or monotonic-time expiry returns the session to `UNVERIFIED`. Monotonic TTL expiry (capped at 300 seconds) is **unconditional** — it requires no observer at all — so the maximum exposure of the orphaned lease is one TTL, ≤ 300 s, after which the next consequential tool is denied with `LEASE_EXPIRED`. Any observer that fires shortens the window further. The residual self-heals: "≥1 observer fires OR expiry ⇒ revoke" catches the lost-ACK lease on the same terms as every other stale lease. As with the dual-observer-miss stale window, WI-3 makes no claim that the mutator gate bounds actions inside the residual interval; the interval is bounded by TTL and the revoke backstop, and the server-side branch-protection / required-CI / independent-review line remains the irreducible backstop for protected-repository mutations.

+Coordinator security review must rerun the real socket/peercred and mutator-gate acceptance suites on an unrestricted Linux runner and obtain the mandated independent Opus-SECREV review before integration.

+# Whole mutator-class lease gate
+
+WI-2 adds the framework-native authorization boundary for Claude (including the supported Claudex overlay) and Pi. Every runtime-reported tool name reaches the lease broker before execution. The gate classifies capabilities by the whole tool class; it never parses a Bash command to decide whether that particular string looks read-only.
+
+## Default-deny policy
+
+While a session is not VERIFIED, only these exact classes are allowed:
+
+- Claude: `Read`, `Grep`, `Glob`, `Ls`, `Find`
+- Pi: `read`, `grep`, `find`, `ls`
+- Both runtimes: the fixed `mosaic_context_recover` primitive
+
+Every other built-in, unknown tool, and custom/MCP tool is consequential by default and is denied. This includes Claude `Bash`, `Edit`, `Write`, and `NotebookEdit`, plus Pi `bash`, `edit`, and `write`. A compromised model therefore cannot bypass Mosaic wrappers by selecting raw `git`, `curl`, `kubectl`, provider, deployment, or filesystem commands inside a generic mutator—the generic mutator itself is blocked before its input executes.
+
+## Broker-owned transition order
+
+The authenticated broker is the sole lease writer:
+
+1. `begin_verification` revokes existing authority and pending tokens first, then records `PENDING_VERIFICATION` and mints one WI-1 single-use promotion token bound to the exact cycle.
+2. `promote_lease` accepts only that session/generation/binding/token combination.
+3. Token consumption commits before the volatile lease becomes VERIFIED. Promotion is last and cannot be reached directly from UNVERIFIED.
+4. `revoke_lease`, a runtime-generation increase, broker restart, or monotonic expiry removes mutator authority.
+
+The initial TTL is capped at the ratified 300-second maximum. A caller may request a shorter positive TTL but cannot lengthen the maximum. WI-3 installs the [compaction observer and generation lifecycle](compaction-revocation.md). Dual compaction-hook miss within an unexpired lease remains the ratified bounded T-A residual: consequential tools are allowed until expiry, with no claimed within-window action bound; once either observer revokes or TTL expires, the next consequential tool is denied.
+
+A receipt is only a future promotion prerequisite. It is not an obedience, residency, or safety proof and never replaces this mechanical gate.
+
+## Runtime adapters
+
+`launch-runtime.py` registers itself with the broker and then `exec`s Claude or Pi so PID/starttime remain the authenticated parent anchor. It exports the broker-minted session ID and an owner-only generation-file reference to descendants; lifecycle hooks advance that file for same-PID replacement generations.
+
+- Claude installs `mutator-gate.py` as an all-tools (`.*`) `PreToolUse` hook.
+- `mosaic claudex` and `mosaic yolo claudex` preserve their isolated `CLAUDE_CONFIG_DIR`, merge the mandatory hook into that isolated `settings.json`, and use the same register-before-exec launcher. Malformed or symlinked isolated settings deny launch.
+- Pi invokes the same executable from its `tool_call` handler.
+
+The executable submits the runtime's actual tool name to `authorize_tool`. Missing identity, malformed input/reply, timeout, broker unavailability, or denial exits with status 2 and blocks fail-closed.
+
+## Runtime-launch choke-point and permanent guard
+
+Every repository-owned Claude/Pi launch entry converges on `launch-runtime.py`, either directly or through `mosaic` → `execLeaseGatedRuntime`. PRDY init/update and QA remediation invoke the wrapper directly so their existing prompts, dangerous-permission behavior, working directory, and environment survive without skipping broker registration. The raw Claude `--dangerously-skip-permissions` primitive is owned only by `launch-runtime.py`; callers request semantic `--dangerous` mode, and the wrapper validates Claude before injecting the primitive. `@mosaicstack/coord` rewrites direct Claude commands to `mosaic claude` and rejects unknown custom Claude launchers.
+
+`check-runtime-launches.py` is the permanent completeness guard. It scans production shell, TypeScript/JavaScript, Python, and data launch definitions under `packages/`, `apps/`, `plugins/`, and `tools/`; direct literal, absolute-path, process-API, dynamic, command-substitution, `eval`, and variable-execution runtime launches fail. Shell comments are stripped with quote awareness, wrapper prefixes are tokenized with `shlex`, and only an invocation in command position with `--runtime` before the command separator is gated. Literal and tracked-variable command tokens use one terminal resolver after any nesting of `exec`, `command`, `nohup`, or `env` plus assignments. A direct command always wins over an inert marker on the same line. Independently, the raw dangerous primitive anywhere outside the choke-point is RED.
+
+The command parser is a best-effort CI defense, not a complete shell interpreter. Alias/function redefinition, sourced commands, generated scripts, and encoded pipelines are intentionally residual rather than an invitation to chase an unbounded shell language. Two runtime controls backstop that residual surface: primitive ownership rejects a dangerous launch even when command identity is alias-indirected, and Claude's global `.*` `PreToolUse` hook invokes the broker gate for non-dangerous launches. Without `MOSAIC_LEASE_SESSION_ID`, representative read, mutator, and custom/MCP tools all fail closed with `GATE_UNAVAILABLE`. Hook absence or replacement remains in the documented T-C boundary.
+
+### Parser stopping criterion
+
+- **A — realistic parser matrix:** comments, inert strings/assignments, heredocs, continuations, chained commands, command substitution, `eval`, bare tracked variables, and quoted/unquoted tracked variables behind `exec`, `command`, `nohup`, or `env` are permanent RED regressions. Prefix-variable forms are covered in both multiline and same-line assignment shapes.
+- **B — residual backstops:** a dangerous alias-indirected launch is RED solely through primitive anchoring; a parser-missed non-dangerous alias launch is paired with an acceptance test proving the global all-tools hook denies every representative tool class as `GATE_UNAVAILABLE` without a lease.
+- **C — independent fresh review:** the parser class is considered complete only when reviewers find no new non-overlapping realistic evasion on the exact head. A and B are repository evidence; C is supplied by the fresh review round.
+
+All three layers are load-bearing and complementary. The guard is mandatory in `@mosaicstack/mosaic`'s test script, so root CI fails on a future realistic bypass. Real-socket tests separately prove PRDY init/update and QA receive broker sessions and deny an unverified mutator.
+
+The live inventory is emitted by:
+
+```bash
+python3 packages/mosaic/framework/tools/lease-broker/check-runtime-launches.py --root . --json
+```
+
+| Production launch family                               | Gated entries |
+| ------------------------------------------------------ | ------------: |
+| `@mosaicstack/coord` default/configured Claude command |             2 |
+| Fleet runtime start                                    |             1 |
+| QA remediation + generated QA command                  |             2 |
+| Orchestrator command construction/session launches     |             3 |
+| PRDY init/update                                       |             2 |
+| Mosaic Claude/Pi/Claudex adapter and wrapper boundary  |             4 |
+| **Total**                                              |   **14 / 14** |
+
+## Assurance boundary
+
+This closes T-A after an observer fires or lease expiry and T-B for in-runtime tool calls. Hook/extension absence, a runtime executing outside the gated launcher, ptrace/same-UID broker replacement, and other fully rotted behavior remain T-C. Server-side branch protection and required PR review/CI remain the irreducible line for protected repository mutations.

-| Probe | Verdict | Short result |
-| --- | --- | --- |
-| P1 launcher topology + ancestry | **PASS** | Real Mosaic→Pi and Mosaic→Claude chains reached the registered anchor; real Claude `SessionStart` hook ancestry accepted; same-UID sibling with the minted victim ID rejected. |
-| P2 Pi last-position + nonce map | **PASS** | Real Pi proved last-or-closed; `message_end` mapped exact `toolCallId → requestNonce` before `tool_call`; provider-response hook occurred before stream consumption/content completion. |
-| P3 same-PID generation revocation | **PASS** | Same Pi PID/starttime persisted through reload/fork/new/resume while broker generations increased; reload revoked a prior `VERIFIED` generation. |
-| P4 `SO_PEERCRED` + socket posture | **PASS** | Real Unix socket peer PID/UID/starttime matched `/proc`; 0700 directory + 0600 socket demonstrated. Same-UID counterfeit replacement remains explicitly T-C without a distinct principal/authenticated response. |
-| P5 source invalidation | **PASS** | Missing, oversize, and hash-mismatched fragments each refused injection/promotion, revoked broker state, and blocked the exact emitted tool call. |
-| P6 atomic injection | **T-C GAP** | Both runtimes empirically delivered a complete single block/message, but neither installed runtime contract states an **atomic/prefix-preserving** transport guarantee. Observation is not a guarantee; A-v5-1/T27 cannot be admitted. |
-
-**Planner return item:** P6. The evidence establishes successful complete delivery in these runs, not the required invariant that the harness cannot middle-drop/replace bytes while preserving the terminal token. Per R1, such a middle-drop is not receipt-detectable. It is therefore classed **T-C**, not assumed away.

-
-### Real topology observed
-
-The installed Mosaic launcher does **not** replace itself with the runtime despite its `execRuntime` name; installed `launch.js:668` uses `spawnSync`. The Gate0 anchor first registered, then `execvpe` replaced the anchor with the real `mosaic yolo` process (PID/starttime retained). Mosaic remained the stable parent while it spawned the runtime.
-
-Pi run:
-
-```text
-anchor before exec: pid=4010843 starttime=365919858 exe=/usr/bin/python3.11
-anchor after exec:  pid=4010843 starttime=365919858 exe=/usr/bin/node

-Claude supported-hook run (latest capture):

-  -> node/mosaic anchor pid=4011129 starttime=365920380
-```
-
-The stream independently recorded the real hook firing:
-
-```json
-{"type":"system","subtype":"hook_started","hook_name":"SessionStart:startup","hook_event":"SessionStart"}
-{"type":"system","subtype":"hook_response","hook_name":"SessionStart:startup","exit_code":0,"outcome":"success","stdout":"...GATE0_P1_SUPPORTED_HOOK_ANCESTRY_ACCEPTED..."}
-```
-
-### Authentication and sibling substitution
-
-The broker minted the logical ID on first peercred contact and keyed the anchor by `(pid,starttime)`. It took the hook/extension PID from `SO_PEERCRED`, walked `/proc/<pid>/stat`, and re-read every starttime before accepting.
-
-Real Pi acceptance excerpt:
-
-```json
-{"peercred":{"pid":4011046,"uid":1001,"gid":1001},"decision":"ACCEPT","reason":"ancestry-reaches-registered-anchor","starttimes_rechecked":true}
-```
-
-A separately spawned same-UID sibling was given the real minted victim ID. Its ancestry did not reach the anchor:
-
-```json
-{"attacker_uid":1001,"victim_session_id_known":true,"broker_decision":"REJECT","broker_reason":"victim-id-known-but-ancestry-mismatch"}
-```
-
-The same rejection occurred in both Pi and Claude runs. This is positive runtime evidence for D1/T15a under the supported non-daemonizing topology.

-- [`evidence/raw/P2-provider-timing.txt`](./evidence/raw/P2-provider-timing.txt)
-
-### Last-or-closed evidence
-
-Real Pi argv/load order with the probe last:
-
-```json
-{"extensions":[".../mosaic-extension.ts",".../pi_gate0_extension.ts"],"lastPosition":true,"gateState":"UNVERIFIED_READY","pid":4004545}
-```
-
-A second real Pi launch deliberately appended a later handler:
-
-```json
-{"extensions":[".../mosaic-extension.ts",".../pi_gate0_extension.ts",".../pi_later_extension.ts"],"lastPosition":false,"gateState":"CLOSED_NOT_LAST","pid":4005692}
-```
-
-Thus the invariant observed is exactly **last or closed**, not an asserted registration order.
-
-### Exact nonce → tool-call-ID map
-
-In one real GPT-5.6 Sol Pi response, sequence 5 completed the assistant tool-call message and bound its exact ID:
-
-```json
-{"seq":5,"event":"message_end","requestNonce":"e5a82358-a6c9-490b-a0de-2e1f1d9b8d79","toolCallIds":["call_bgGE...57c"],"nonceMappings":[{"toolCallId":"call_bgGE...57c","requestNonce":"e5a82358-a6c9-490b-a0de-2e1f1d9b8d79"}]}
-```
-
-The following `tool_call` was sequence 6 and carried the same ID/nonce:
-
-```json
-{"seq":6,"event":"tool_call","toolCallId":"call_bgGE...57c","mapping":{"nonce":"e5a82358-a6c9-490b-a0de-2e1f1d9b8d79","verified":true},"allowed":true}
-```
-
-The harmless tool executed at sequence 7 with that same tool-call ID. No session-global “current epoch” was borrowed.
-
-### `after_provider_response` is not assistant-content observation
-
-A deterministic localhost HTTP provider was used only to force headers/status exposure through the real Pi transport. Actual order:
-
-```json
-{"seq":4,"event":"before_provider_request"}
-{"seq":5,"event":"after_provider_response","status":200,"assistantContentAvailableAtThisHook":false,"timing":"headers/status before stream consumption"}
-{"seq":6,"event":"message_end","role":"assistant","assistantContentObserved":true}
-```
-
-```text
-headers_hook_precedes_completed_message=True
-```
-
-This positively confirms SPEC-v5’s precision correction: receipt content is observed at `message_end`; `after_provider_response` is status/headers before stream consumption.

-## P3 — Same-PID `runtime_generation` bump revokes prior lease (D4)

-**Verdict: PASS**

-```
-
-Full output: [`evidence/raw/P2-P3-P5-P6-pi.txt`](./evidence/raw/P2-P3-P5-P6-pi.txt).
-
-The real Pi process identity remained:
-
-```text
-pid=4004545 starttime_ticks=365907677 uid=1001
-```
-
-Broker state around reload:
-
-```json
-{"event":"runtime_generation_bump","reason":"startup","old_generation":0,"new_generation":1,"new_lease_state":"UNVERIFIED"}
-{"event":"probe_lease_promoted","generation":1,"new_lease_state":"VERIFIED"}
-{"event":"runtime_generation_bump","phase":"shutdown","reason":"reload","old_generation":1,"new_generation":2,"prior_lease":"VERIFIED","prior_lease_revoked":true,"new_lease_state":"REVOKED"}
-{"event":"runtime_generation_bump","phase":"start","reason":"reload","old_generation":2,"new_generation":3,"new_lease_state":"UNVERIFIED"}
-```
-
-The same `(pid,starttime)` then emitted monotonic bumps for real `fork`, `new`, and `resume` replacement flows, reaching generation 12. Pi 0.80.7 emitted an additional conservative `session_start` callback in each of those replacement flows; the broker bumped again rather than reusing authority. This is an availability/idempotence consideration for implementation, not a fail-open result.

-```
-
-Achievable unprivileged posture on this host is a user-owned 0700 parent plus 0600 socket. That excludes other UIDs and positively authenticates the connecting kernel PID/UID/GID. It does **not** stop another process running as `hermes` from unlinking/rebinding the socket. A claim stronger than T-C against counterfeit replacement therefore requires the ratified distinct-principal system service or authenticated broker responses. No stronger claim is made.

-
-### Positive empirical observations
-
-**Pi:** The real `context` hook returned exactly one additional `AgentMessage`; the prior message prefix hash was unchanged. The real final provider payload contained exactly one occurrence in one content item, and the real model copied all bytes exactly:
-
-```json
-{"event":"context_return","inputCount":1,"outputCount":2,"injectionDecision":"ONE_ATOMIC_AGENT_MESSAGE","prefixPreservedByReturn":true,"blockLength":108,"blockSha256":"99c3...a0dd"}
-{"event":"before_provider_request","markerOccurrences":1,"markerPaths":["$.input[1].content[0].text"],"finalPayloadValid":true}
-{"event":"message_end","exactContextBlockCopied":true,"assistantTextSha256":"99c3...a0dd"}
-```
-
-**Claude:** The real `SessionStart` hook emitted one `hookSpecificOutput.additionalContext` string. Claude’s stream recorded successful hook execution, and the real model’s exact copied block matched byte length and SHA-256:
-
-```text
-block_length=116
-block_sha256=ef6377d63552af075f4f4adec00165988418c5f46a992f4dce8e678b56fd34ac

-assistant_copy_exact=True
-```
-
-### Why this is not a PASS
-
-The installed Pi documentation says only that `context` receives a deep copy and may return `{ messages }`. The installed Claude documentation says only that `additionalContext` enters/adds to context/system prompt. The exact search result was:
-
-```text
-NO MATCH: neither installed runtime document states an atomic/prefix-preserving transport guarantee.
-```
-
-One or several successful complete deliveries cannot prove the transport invariant needed by A-v5-1. In particular, a harness-side middle deletion/replacement that preserves the terminal receipt is not detectable by the receipt. That is precisely R1’s assurance boundary. Therefore:
-
-- absent or prefix-truncated terminal token: receipt-detectable;
-- middle-drop preserving the tail token: **not receipt-detectable**;
-- no documented runtime contract excludes that transform;
-- classification: **T-C contract gap**.
-
-No atomicity claim is inferred from empirical success.

-After an initial review identified a session-global P2 correlation flaw, the probe was changed to queue request-scoped cycles from `before_provider_request` through assistant `message_end`; all runtime probes were re-run and raw checksums regenerated. The final independent review command was:
-
-```bash
-~/.config/mosaic/tools/codex/codex-code-review.sh \
-  -b d801d6c4c8a984d6a95033c49714210018d3d9a8 \
-  -o /tmp/827-gate0-rereview.json
-```
-
-Final review: **APPROVE**, confidence 0.91, 18 files reviewed, 0 blockers, 0 should-fix findings, 0 suggestions.
-
-## Final admission decision
-
-Gate0 requires every item to produce positive runtime evidence. P6 does not. **Do not admit WI-1..WI-7. Return A-v5-1/T27 to planner review.**
-
-No feature work, push, PR, merge, or issue closure was performed.

-## Independence (G2)
-
-Distinct Opus §3-conformance reviewer (Gate-16 author≠reviewer). I did **not** build this harness (author =
-ms-rev-826); I am not Mos. This verdict is my own; the author did not author or edit it. Byte review only — **ran
-nothing** (no harness, no broker, no sockets/state). Reviewed across v1 (FAIL, live-broker launch path) → v2 (PASS,
-later found runtime-dead producer) → this v3 (closes the live-path review-gap).
-
-## Why v3 (the review-gap closed)
-
-v2 PASS @`839d156f` credited the static presence of `lease_anchor_registered` as isolation proof. At FIRE the
-producing path was **dead**: the harness drove the *released* `mosaic` binary, which launched Pi **ungated**, so
-`register_anchor` never ran. Static presence of an assertion ≠ its producing path executing. v3 requires the
-producing path to be **live at runtime**.
-
-## Surface-by-surface
-
-| Surface | Result | Evidence (file:line) |
-|---|---|---|
-| Pushed bytes fetched + sha-verified | ✅ | sha256==`2f11c939…`, 17162B, no sentinel |
-| (a) LIVE-PATH — drives the **gated** launcher, producer in the exec chain, NOT released `mosaic`/plain `execRuntime` | ✅ | launch = `python3 <GATED_LAUNCHER> --runtime pi -- pi …` :357-364; `GATED_LAUNCHER=…/launch-runtime.py` :32, pinned `GATED_WI_HEAD=abd2791f…` :31; `mosaic yolo`/`execRuntime` = 0 hits. `launch-runtime.py` unconditionally `register_anchor`s before `execvpe`, so the producer is in the invoked chain |
-| (b) Fail-closed precondition present + correct (gated + fixture-socket, refuses otherwise), invoked before all launches | ✅ | `gated_launcher_precondition` :229-251, called :342 **before** broker Popen :343 and Pi launch :357. Verifies (ii) `MOSAIC_LEASE_BROKER_SOCKET==fixture` :232 + fixture in tempdir :234; (i) launcher HEAD==`abd2791f` :243 + source has `register_anchor` **before** `execute(command[0]…)` and reads `MOSAIC_LEASE_BROKER_SOCKET` :246-250. Raises `RuntimeError` (no run) on any miss :233/:235/:242/:244/:250 |
-| (c) Fixture-socket isolation (no live/default broker reachable, single p3 fixture, non-destructive) | ✅ | `pop("MOSAIC_LEASE_BROKER_SOCKET")` :330 + set to fixture socket :334; harness invokes `launch-runtime.py` directly so it reads `MOSAIC_LEASE_BROKER_SOCKET`=fixture with **no** `defaultLeaseBrokerSocket`/XDG/`/run/user` fallback in the path; `register_anchor` served by the single p3 fixture; `p3_generation_broker.py` **zero diff** vs `839d156f` (in-memory volatile hex-256 session `secrets.token_hex(32)`, nothing durable outside tempdir) |
-| (d) Assertion INTACT (`lease_anchor_registered` + `session_id_shape=="hex-256"`, not softened/optional/repointed) | ✅ | :256-258 (event), :298 (`hex-256`), folded into single-PID/starttime identity set :286. Not Case C |
-| spawns ONLY p3_generation_broker.py | ✅ | broker Popen = `HERE/p3_generation_broker.py` :343-346; the pinned launcher is a register-before-exec launch wrapper, not a 2nd broker |
-| promotion = fixture-only (not P2-banked) | ✅ | `d4_fixture_promote` "not a P2 evidence-gathering authorization"; `promote-probe` in-memory; precondition target only; no P2 import |
-| D4 assertions complete | ✅ | same-PID+starttime persist (incl. launcher registration) :284-288; gen strictly increases :290-293; reload revokes genuinely-VERIFIED prior :299-300; new→`MUTATOR_UNVERIFIED` :301; prior→`STALE_GENERATION` :302; lifecycle boundaries :294-297 |
-| P5 / P6 / P2-bank / retry-launder / live-effect / mechanism-change / scope-widen ABSENT | ✅ | 0 hits: `source-invalid`/`run_open`/`atomic`/`p2_provider`/`p5`/`p6`/`pi_gate0_run`/`retry`; no real-broker path; the only mechanism change is the required launch-routing fix (release→pinned gated launcher), which narrows scope, not widens |
-| non-destructive | ✅ | per-run `tempfile.mkdtemp` fixtures; p3 in-memory + tempdir socket/log only; reads `/proc/<pid>/stat` (read-only) |
-| deterministic | ✅ | isolated tempdir per run; deterministic assertions; session-id randomness is **shape**-asserted only (`hex-256`), `setdefault` idempotent |
-| hidden exec-at-import | ✅ absent | only `if __name__ == "__main__": main()`; docstring: not executed until FIRE |
-
-## Verdict
-
-**PASS @ `ace60667`** — (a) LIVE-PATH, (b) fail-closed precondition, (c) fixture-socket isolation, and
-(d) intact assertion all hold, with zero out-of-scope surface. The v2 review-gap (runtime-dead producer via the
-released ungated `mosaic`) is structurally closed: the harness no longer invokes `mosaic` at all — it invokes the
-pinned `abd2791f` `launch-runtime.py` directly (register-before-exec), and refuses to launch unless the launcher is
-that pinned gated register-before-exec binary bound to this run's fixture socket.
-
-**Findings: none.**
-
-## Scope reminder (not a finding)
-
-Per §3/§5 of the amendment, producing this evidence **executes** the Gate0 mechanism (launches processes, creates
-socket/state artifacts, exercises revocation). This review clears the **bytes**; **FIRE remains separately gated on
-Mos's explicit post-clear GO** and is not authorized by this review.

-## Independence (G2)
-
-Distinct Opus §3-conformance reviewer (Gate-16 author≠reviewer). I did not build this harness (author = ms-rev-826);
-I am not Mos. This verdict is my own; the author did not author or edit it. Byte review only — **ran nothing** (no
-harness, no broker, no sockets/state). Prior v3 PASS (`ace60667`, pinned `abd2791f`) is correctly **superseded**:
-pinning a pre-`66b1e0a0` ancestor made D4 an in-memory socket simulation (hollow gate). v4 requires
-mechanism-fidelity within isolation (Jason R1).

-| Launcher bytes contain the file-backed mechanism | ✅ | precondition requires `register_anchor` :290, `initialize_runtime_generation(generation_file, generation)` :291, `generation-{session_id}.state` :294, `MOSAIC_LEASE_GENERATION_FILE` :295, `read_runtime_generation`+`bump_runtime_generation` in `lease_generation.py` :296-299; order `register < initialize < execute` :302-303 |

-
-| # | Requirement | Result | Evidence |
-|---|---|---|---|
-| i | Extension bumps `generation-{sid}.state` via the real helper, not in-mem | ✅ | ext `lifecycle()` calls `broker({action:'bump-generation'})` at every post-start boundary (harness :200-205); broker `bump-generation` → `bump_runtime_generation(generation_environment(identity))` (broker :119-120) |
-| ii | Broker reads generation via `read_runtime_generation`, not an in-mem counter | ✅ | broker loads the pinned module (`--generation-module`, :52-54); `file_generation()` = `read_runtime_generation(...)` (:77-78); authorize-probe reads `current_generation = file_generation(identity)` (:154); lifecycle `new_generation = file_generation(identity)` (:201). The in-mem `generations` dict is only an old-value cache for the monotonic guard (:199-204), never the authorization authority |
-| iii | `assert_d4` observes the FILE-BACKED transition | ✅ | `state_file_source` = all records `generation_source=="state-file"` (harness :370-372); `state_file_drives_lifecycle` = state-bumps == lifecycle generations[1:] (:368-369); `new_generation_unverified→MUTATOR_UNVERIFIED` :382; `prior_generation_stale→STALE_GENERATION` :383; `verified_revoked_on_reload` :380-381 — not a socket-only bump |
-| iv | `.state` bound to per-run fixture temp root | ✅ | broker `generation_environment` **raises if `state_path.parent != socket_path.parent`** (:73-74); `state_file_in_fixture_root` (:373-376); precondition forbids inherited `MOSAIC_LEASE_GENERATION_FILE` (:255-256) and requires socket in `gettempdir()` (:274-275); launcher/broker agree on `socket_path.parent / generation-{sid}.state` |

No unnamed/future inherited var survives |
-| b4-3 `--runs` exactly 3, fail-closed otherwise | ✅ | `add_argument("--runs", type=int, default=3, choices=(3,))` :591 (argparse rejects any other value) |

-## MUST-BE-ABSENT sweep
-
-`P5` / `P6` / `P2-bank` / `retry-launder` / `mosaic yolo` / `execRuntime` / `run_open` / `atomic-observation` /
-`pi_gate0_run` = **0 hits** (both files). Extension invokes only `bump-generation` / `lifecycle` /
-`authorize-probe` / `promote-probe`. No live/prod/real-broker path (single fixture broker; allow-list env; launcher
-pinned to fixture socket). No `.state`/gen-file path outside the fixture temp root (broker `generation_environment`
-raises otherwise). §4 live effect: none. No extra broker/socket beyond the single p3. No exec-at-import (both files
-`__main__`-guarded). Mechanism change is confined to the mandated R1 observation-fidelity deepening + BAR4 hardening;
-no scope-widen of what the probe touches.
-
-## Observations (transparency — not findings)
-
-1. The fixture broker retains a **dormant `source-invalid` action** (:179-194, P5-adjacent, in-mem). It is
-   **never invoked** by the harness or its embedded extension (verified: extension actions are only
-   bump/lifecycle/authorize/promote), and `assert_d4` never observes it — so the probe does **not** exercise or bank
-   P5. Pre-existing shared-fixture code, unchanged. Surfaced so Mos may, if desired, apply a stricter
-   purge-dormant-P5-from-the-fixture standard; under the "what the probe TOUCHES/does" framing it is not a violation.
-2. Fixture `HOME` receives a **read-only copy** of the operator's `~/.pi/agent` `settings.json`/`auth.json`/`bin/fd`
-   (:430-440, `shutil.copy2` into the fixture) so real Pi can authenticate to the model provider. It reads operator
-   state; it does not write/mutate operator HOME and does not emit/log credential material. Confined to the fixture.
-
-## Verdict
-
-**PASS @ `48484938`** — BAR1 (traceability to shipped f4008307 mechanism) + BAR2 (genuine file-backed generation,
-i–iv) + BAR3 (live-path / fail-closed precondition / isolation / intact assertion) + BAR4 (b4-1..b4-5) all hold,
-with zero out-of-scope surface exercised. The v3 hollow-gate (ancestor pin, in-mem simulation) is structurally
-closed: evidence now attests the shipped WI-3 D4 file-backed generation mechanism, launcher pinned by head+sha256,
-child env write-confined by allow-list, integrity `-O`-safe with a derived PASS.
-
-**Findings: none.**
-
-## Scope reminder (not a finding)
-
-Per §3/§5 of the amendment, producing this evidence **executes** the Gate0 mechanism. This review clears the
-**bytes**; **FIRE remains separately gated on Mos's explicit post-clear GO** and is not authorized by this review.

-**byte review only, ran nothing**, that **did not build** this harness (author = ms-rev-826) and **is not Mos**. The

-independent of the git signer.
-
-## Hygiene delta (v4 `48484938` → v5 `7f975b95`) — items (a)+(b): CLOSED
-
-Full `diff` of both files shows the delta touches **only** these:
-
-- **(a) Creds scrubbed — CLOSED.** New `scrub_fixture_credentials(root)` (:467-475): `shutil.rmtree(root/"home"/".pi"/"agent")` then a fail-closed re-check `if copied_agent.exists(): raise` (:473-474). Invoked in the **outermost `finally`** (:598), **after** pi/broker cleanup and **before** `return root` (:600) — so it runs on the **success path too**. The scrub target exactly matches the only copy site (`target_agent = fixture_home/".pi"/"agent"`, :433). `isolated_environment` was moved inside the `try` (:485) so the scrub finally also covers a partial env-setup failure. No copied agent credential/config subtree (incl. `auth.json`) survives in any retained root. ✅
-- **(b) `source-invalid` handler REMOVED — CLOSED.** `grep source-invalid / source_invalidation_revoke == 0` across **both** files. Broker delta is solely the deletion of the old `:179-194` block. ✅
-
-## (c) Everything-else byte-stable vs `48484938` — HOLDS
-
-Diff confirms **no other hunks**. Re-swept intact: traceability `GATED_WI_HEAD=f4008307` (:33) + `GATED_LAUNCHER_SHA256=e950e4224e…` (:35); fidelity `read_runtime_generation`/`bump_runtime_generation` + `generation_source=="state-file"` + `new→MUTATOR_UNVERIFIED`/`prior→STALE_GENERATION`; `lease_anchor_registered` + `hex-256`; `-O`-safe (0 bare `assert`, PASS derived `all(checks.values())`); allow-list literal env (0 `os.environ.copy`); `--runs choices=(3,)`; fail-closed precondition; single p3 broker. Blockers 1-4 (inherited env / `--runs`≠3 / cleanup-misses-setup-failure / `-O`-strips-checks) remain closed.
-
-## (d) ABSENT sweep — 0
-
-`P5`/`P6`/`P2-bank`/`retry-launder`/`mosaic yolo`/`execRuntime`/`run_open`/`atomic`/`pi_gate0` = 0 (both files);
-extension invokes only `bump-generation`/`lifecycle`/`authorize-probe`/`promote-probe`; no exec-at-import.
-
-## Homelab carry-forward — NEW-5 / NEW-6: **PRESENT → FAIL**
-
-### 🔴 NEW-6 — GATED_WI_ROOT resolves wrong / non-portably (CONFIRMED)
-`GATED_WI_ROOT = HERE.parents[3].parent / "stack-cr-wi3-revoke"` (:32). For the harness at
-`…/agent-work/stack-cr-wi0-gate0/docs/compaction-refresh/probes/`, this computes
-**`/home/hermes/stack-cr-wi3-revoke` — which does not exist**. The actual f4008307 worktree is
-`/home/hermes/agent-work/stack-cr-wi3-revoke` = `HERE.parents[3] / "stack-cr-wi3-revoke"`. The traversal is
-**off-by-one** (`.parents[3].parent` should be `.parents[3]`), and it additionally hardcodes the worktree name — a
-non-portable relative assumption. On this host the precondition therefore fail-closes ("gated WI launcher is
-unavailable") and the probe cannot locate/execute the pinned launcher at all. **Real resolution defect** (independently
-computed by path arithmetic; harness not run). **file:line — :32.**
-*Fix:* derive `GATED_WI_ROOT` from a portable, explicit anchor (e.g. an env-provided path validated to be the
-f4008307 worktree, or `HERE.parents[3] / "stack-cr-wi3-revoke"` with existence+HEAD assertion), not `.parents[3].parent`.
-
-### 🔴 NEW-5 — launcher precondition is check-then-exec, not pinned-executed-bytes (CONFIRMED)
-The precondition hashes `launcher_bytes = GATED_LAUNCHER.read_bytes()` (:280) against `GATED_LAUNCHER_SHA256` (:287),
-but the launcher is **executed separately** via `PiRpc([sys.executable, str(GATED_LAUNCHER), …])` (:514-515), which
-opens and **re-reads the file at exec time**. There is **no fd-handoff and no exec-from-verified-copy**, so the
-verified snapshot does **not** bind the executed bytes. The window between check (:287) and exec (:514-515) spans the
-broker `Popen` + `wait_path` (≤20 s) — a genuine **check-then-exec TOCTOU / mutable-path trust**; the `git rev-parse
-HEAD` check (:285-286) is likewise on a mutable HEAD, not the executed bytes. Per the bar this is a real gap.
-**file:line — hash :280/:287 vs exec :514-515.**
-*Fix:* execute the exact verified bytes with no window — e.g. read once, verify, and exec from a fixture-private
-copy of the verified bytes (or `python3 /proc/self/fd/<verified-fd>`), so the hashed bytes == executed bytes.
-
-## Verdict
-
-**FAIL @ `7f975b95`.** The hygiene delta itself is correct — (a) creds scrub (fail-closed finally, success path,
-every retained root) and (b) `source-invalid` removal both landed cleanly, (c) everything else is byte-stable vs
-`48484938`, and (d) the absent sweep is 0. **However**, homelab's NEW-5 (check-then-exec launcher TOCTOU / not
-pinned-executed-bytes) and NEW-6 (GATED_WI_ROOT off-by-one/non-portable resolution) are **present in these bytes**;
-the addendum requires both **closed** for PASS. Not softened. Returns to author (ms-rev-826) — not to a builder
-re-review, no PASS-launder.
-
-**Findings:** NEW-6 (`p3_d4_focused_run.py:32`); NEW-5 (`p3_d4_focused_run.py:280/:287` vs `:514-515`).
-
-## Scope reminder (not a finding)
-
-Producing this evidence **executes** the Gate0 mechanism (§3/§5). This review clears **bytes** only; FIRE remains
-separately gated on Mos's explicit post-clear GO — and is moot until this FAIL is remediated.

-
-**Principal:** Mos (orchestrator, merge authority for the mosaic-stack governance lane).
-**Committed under a DISTINCT git identity** (`mos-orchestrator@mosaic.local`) — deliberately NOT the
-`ms-lead-reviewer@mosaic.local` lane signer — so this record stands as a *distinct-identity*

-
-**Verify class:** independent provider-byte read (guarded `git show <full-40>:path | sha256sum` from a

-
-## Findings — VERDICT: byte-scope + mechanism + hygiene **PASS**
-
-**Anchors.** Harness sha256 matches (27366 B). review-v6 (`23c0caca`) parent == harness commit
-`2d54a9dd`; review touches only the review `.md` (+82 lines, 1 file). Broker
-(`p3_generation_broker.py`) delta vs `48484938…` = **exactly** the 16-line `action=="source-invalid"`
-handler purge, byte-stable otherwise.
-
-**NEW-6 (GATED_WI_ROOT off-by-one) — CLOSED.** `resolve_gated_wi_root()` selects the worktree by
-`git worktree list --porcelain` enumeration, requires a UNIQUE match on `HEAD==GATED_WI_HEAD`
-(`f400830738998db105107a2a4c69c7f2a2a6fd5d`) AND `branch==refs/heads/feat/830-compaction-revoke`,
-then fail-closed re-validates (`is-inside-work-tree==true`, `rev-parse HEAD==GATED_WI_HEAD`);
-`RuntimeError` on ambiguity/mismatch. The `HERE.parents[3].parent / "stack-cr-wi3-revoke"` off-by-one
-and the hardcoded `/home/hermes/...` literal are **gone** — portable, zero hardcoded path.
-
-**NEW-5 (TOCTOU / pinned-executed-bytes) — CLOSED via approach (i), as mandated.** The `git`-object
-sha256 pin (`GATED_LAUNCHER_SHA256 = e950e422…`) is the trust anchor. Ordering/marker `.find()`
-heuristics are downgraded to explicitly diagnostic-only ("never a substitute for the pin"). In
-`launch_verified_pi()` the executed working-tree file is re-hashed against the pin **in the statement
-immediately before `Popen`** (no interleaved yield/IO), and the launcher is executed **in place at the
-pinned worktree path** — the higher-risk approach (ii) copy-to-fixture (previously at `7ff63cd5` /
-`6164dc07`) is **reverted** (the only remaining `shutil.copy2` is the legitimate credential copy, not a
-launcher copy). Residual sub-statement TOCTOU window on a local file inside a non-adversarial operator
-fixture is within this probe's threat model; the gross precondition→much-later-exec gap homelab flagged
-is closed.
-
-**Hygiene — CLOSED.** `scrub_fixture_credentials(root)` removes the entire `.pi/agent` subtree in a
-`finally` block (nested try/finally, after `pi.close()` + broker shutdown, before `return root`) and
-`RuntimeError`s if the scrub fails — credentials are removed from retained evidence; logs retained.
-
-**Invariants byte-stable (all INTACT):** assertion `lease_anchor_registered`; file-backed fidelity
-checks (`generation_source=="state-file"`, `state_file_in_fixture_root`, `MUTATOR_UNVERIFIED`,
-`STALE_GENERATION`); `-O`-safe (0 bare `assert`); allow-list env (0 `os.environ.copy`); single broker;
-`--runs choices=(3,)`; ABSENT-sweep (`yolo`/`execRuntime`/`p3_bank`/`promote_p2`/`retry`) = 0.
-
-**R1 mechanism-fidelity boundary — HELD.** D4 exercises #830's real file-backed revocation
-(`generation-{sid}.state` / `MOSAIC_LEASE_GENERATION_FILE`, from `66b1e0a0`); `.state` stays inside the
-fixture temp root; fixture-socket / child-write-escape / gettempdir isolation preconditions preserved;
-launcher exec is in place at the pinned worktree (same surface as R1, not a new production/live
-surface). **No path escapes the fixture root.** BEYOND-R1 tripwire NOT tripped.

-## Independence
-
-- **Substantive principal-independence** of review-v6 is satisfied by an orchestrator-dispatched,
-  builder-distinct Opus SECREV (`ms-secrev-828`, byte-only, non-builder) — that IS the substance of
-  Gate-16.
-- The shared `ms-lead-reviewer` git signer on harness+review commits is **evidentiary, not
-  substantive**. It is resolved by (1) this Mos co-attestation committed under a **distinct** identity
-  (`mos-orchestrator`), and (2) a homelab third-principal verify under its own distinct identity —
-  i.e. three distinct-identity principals of record.
-- The shared signer is a tracked **fleet-infra tooling-gap** (durable fix = per-lane distinct signers),
-  **not a blocker**.
-
-## Scope of this record — byte-clear, NOT fire-authorization
-
-Producing probe evidence **executes** the Gate0 mechanism; a byte-clear is not a fire-authorization.
-This co-attestation clears the **bytes/scope/hygiene**. FIRE remains gated on: **homelab
-third-principal verify** + **Mos transparency-to-Jason** (real-Pi consumes operator model creds inside
-the isolated fixture, scrubbed post-run, never emitted) + **Mos explicit FIRE GO**. Until then: nothing
-banked, WI-3 #830 held at `f4008307` (unmoved), C-hatch armed (if 3× isolation still no-fire /
-wrong-value / isolation-FAIL → possible Case-C → STOP + escalate to Jason).
-
-**Mos verdict: byte-scope + mechanism + hygiene PASS. Co-attestation of record — committed.**
-
----
-
-## ⚠️ SUPERSEDED — homelab third-principal FAIL raised a stricter bar (evidence-integrity note)
-
-This co-attestation was **byte-clear on the v6 bar ONLY** and self-limited above to *"byte-clear
-ONLY, NOT fire-authorization; FIRE remains gated on homelab third-principal verify."* Homelab (the
-required third principal) subsequently returned **FAIL @2d54a9dd**, and Mos **UPHELD** it — so the v6
-byte-clear this document records is **SUPERSEDED** and does **NOT** authorize FIRE.

-Homelab's substantively-correct deepening (accepted as gate-**strengthening**, not softening):
-1. `launch_verified_pi` hashes the launcher then `Popen`/execve **reopens the path** → statement
-   adjacency shrinks but does not eliminate TOCTOU; hashed-snapshot ≠ executed-bytes.
-2. `lease_generation.py` helper is unpinned, loaded from the mutable worktree → HEAD + launcher-pin
-   do not bind the helper bytes.
-3. `p3_generation_broker.py` executes from the mutable worktree unhashed → reviewed broker bytes need
-   not be the evidence-producing bytes.
-
-For a fail-closed DO-178C evidence gate, **hashed==executed must hold on the FULL executed closure**
-(launcher + helper + broker), which v6 (approach (i) adjacency) does not meet. Mos therefore
-**authorized approach (ii) full-closure materialization** (SHA-pin + materialize the full closure into
-a fixture-private 0700/0600 dir or held verified fds, exec from there, launcher+broker consume the same
-pinned helper; re-hash==f4008307 pins immediately before exec, fail-closed). This rides the existing R1
-authorization + Mos adjudication authority (it deepens isolation of already-authorized touch and stays
-inside the fixture temp root → R1 owner tripwire not tripped; no fresh owner window).
-
-**Live target = v7** (materialized-closure harness, forthcoming). `2d54a9dd` / `23c0caca` / this
-co-attestation (`12914d8`) are **SUPERSEDED**. A fresh Mos co-attestation will be committed on v7

-(1) this Mos co-attestation under a **distinct** identity (`mos-orchestrator`) and (2) a homelab
-third-principal verify under its own distinct identity = three distinct-identity principals of record.
-The prior 2-of-3 (`ms-secrev-828` v9 §3 PASS + `f320d075`) does **not** carry — all three re-verify
-this v10 SHA. Shared signer = tracked fleet-infra tooling-gap, not a blocker.
-
-## Scope of this record — byte-clear, NOT fire-authorization
-
-Producing probe evidence **executes** the Gate0 mechanism; a byte-clear is not a fire-authorization.
-This clears **bytes / scope / mechanism / hygiene on the v10 (v9 + B9 no-site) bar**. FIRE remains
-gated on: **homelab third-principal re-verify** (5th round, own distinct identity) + **Mos
-transparency-to-Jason** + **Mos explicit FIRE GO**. The FIRE GO additionally carries an
-**execution-procedure constraint**: the 3× isolation dispatch must launch the runner under
-externally-enforced **`python -I -S -B p3_d4_focused_run.py`** — a self-reexec is too late, the
-harness's own `site` runs before it could re-add `-S` to itself. Until FIRE GO: nothing banked, WI-3
-#830 held at `f4008307` (unmoved), C-hatch armed (fired-rig only: no-fire / wrong-value /
-assertion-FAIL / isolation-FAIL → possible Case-C → STOP + escalate to Jason).
-
-Prior v10-superseded set: `1c34e3cb` / `e1c9a468` / `f320d075` (and transitively the v7 chain).

-> (`stack-cr-wi3-revoke`, HEAD == `f4008307`) rather than passing over a clone-completeness gap. The
-> broker pin was recomputed from origin `23c0caca`.
-
-## Findings — VERDICT: byte-scope + mechanism + hygiene **PASS** (v7 full-closure bar)
-
-Homelab's stricter bar — **hashed==executed on the FULL executed closure (launcher + helper + broker)**
-— is met. Verified at the source, not accepted on the review's assertion:
-
-**B5 conjunction (the load-bearing repair) — HELD, all three legs:**
-- **(a) materialized from pinned git-object bytes, NOT the mutable worktree.** `materialize_closure`
-  fetches each member via `git_object_bytes` (`git show {commit}:{path}`), then
-  `sha256(data) == pin` **fail-closed** (`RuntimeError` on mismatch) before use.
-- **(b) no writable window hash→consume.** `pinned/` is `mkdir(mode=0o700)`; each file is written with
-  `os.open(O_WRONLY|O_CREAT|O_EXCL|O_CLOEXEC, 0o600)` — `O_EXCL` refuses a pre-planted file. No `chmod`,
-  no `os.rename/replace`, no `symlink`, and nothing re-opens a pinned file for write (grep = 0). The
-  pinned bytes are immutable within the fixture threat model between hash and exec.
-- **(c) re-hash == pin IMMEDIATELY before each exec, no interleaved yield.** Launcher: re-hash then
-  `return PiRpc(command,…)` whose `__init__` **first statement** is `subprocess.Popen(command,…)` —
-  zero IO/yield/reopen between. Broker + helper: both re-hashed then `subprocess.Popen` on the next
-  line. Adjacency-alone-without-materialization (the v6 defect) is **absent** — all three exec from
-  `pinned/`.
-
-**B6 — helper pinned AND bound to the SAME single copy.** The broker receives
-`--generation-module {closure.generation}` (the pinned helper); the launcher runs from `pinned/` so its
-`import lease_generation` resolves to the sibling pinned copy via `sys.path[0]`. `closure_import_guard`
-AST-parses every member and raises on any non-stdlib import other than the allowed `lease_generation`
-— proving the dependency closure is complete and no unpinned module can enter at runtime.
-
-**Closure = exactly 3 files, materialized inside the fixture root** (`root / "pinned"`). No path escapes
-the fixture temp root; no live/default broker; `.state` remains fixture-bound. **R1 owner tripwire NOT
-tripped** — this deepened isolation of an already-authorized touch, it did not widen the touched surface.
-
-**Invariants (all INTACT):** BAR1 `GATED_WI_HEAD == f4008307` and `merge-base --is-ancestor 66b1e0a0
-f4008307` = YES (file-backed `.state` revocation fidelity present); BAR2 `.state` =
-`socket_path.parent / generation-{sid}.state`, `state_file_in_fixture_root` + `generation_source ==
-"state-file"` checks present; BAR3 `lease_anchor_registered` / live-path / fixture-socket isolation
-intact. `-O`-safe (0 bare `assert`); ABSENT-sweep (`yolo`/`execRuntime`/`p3_bank`/`promote_p2`/`retry`)
-= 0; single broker (1 def + 1 call site); `--runs choices=(3,)`; allow-list env (0 `os.environ.copy`);
-the only `shutil.copy2` is the legitimate `.pi/agent` credential copy (settings/auth/fd), **not** a
-launcher/helper/broker copy — the v6 copy-to-fixture concern is gone.
-
-## Independence
-
-- **Substantive principal-independence** of review-v7 is satisfied by an orchestrator-dispatched,
-  builder-distinct Opus SECREV (`ms-secrev-828`, byte-only, non-builder) — that IS the substance of
-  Gate-16.
-- The shared `ms-lead-reviewer` git signer on both the harness (`ms-rev-826` build) and the review
-  commit is **evidentiary, not substantive**. It is resolved by (1) this Mos co-attestation under a

-  distinct identity — three distinct-identity principals of record. Tracked fleet-infra tooling-gap
-  (durable fix = per-lane distinct signers), **not a blocker**.
-
-## Scope of this record — byte-clear, NOT fire-authorization
-
-Producing probe evidence **executes** the Gate0 mechanism; a byte-clear is not a fire-authorization.
-This co-attestation clears the **bytes / scope / mechanism / hygiene on the v7 full-closure bar**. FIRE
-remains gated on: **homelab third-principal re-verify** (under its own distinct identity) + **Mos
-transparency-to-Jason** + **Mos explicit FIRE GO**. Until then: nothing banked, WI-3 #830 held at
-`f4008307` (unmoved), C-hatch armed (if the materialized-closure rig still no-fire / wrong-value /
-assertion-FAIL / isolation-FAIL → possible Case-C → STOP + escalate to Jason).
-
-**Mos verdict: v7 full-closure byte-scope + mechanism + hygiene PASS. Co-attestation of record —
-committed.**
-
----
-
-## ⚠️ SUPERSEDED — homelab v7 third-principal FAIL @f609a449 raised a stricter bar (evidence-integrity note)
-
-This co-attestation was **byte-clear on the v7 full-closure bar ONLY** and self-limited above to
-*"byte-clear NOT fire-authorization; FIRE remains gated on homelab third-principal re-verify."*
-Homelab (the required third principal) subsequently returned **FAIL @f609a449** (static verify, no
-code run), and Mos **UPHELD** it after independently confirming both findings in source — so the v7
-byte-clear this document records is **SUPERSEDED** and does **NOT** authorize FIRE.
-
-Two residual isolation/binding holes WITHIN the materialized closure (both independently reproduced
-by Mos in the harness source; accepted as gate-**strengthening**, not softening):
-1. **Broker child env not isolated.** `launch_verified_broker` (`:551`) calls `Popen` with **no
-   `env=`** (only `PiRpc.__init__` `:50` passes an allow-listed `env`) → the broker child inherits
-   ambient `os.environ` (PYTHONPATH/PYTHONHOME/PYTHONPYCACHEPREFIX). `closure_import_guard` is a
-   static AST check and cannot bind the child's runtime stdlib resolution.
-2. **Executed bytecode-cache outside the pin.** No `PYTHONDONTWRITEBYTECODE`/`-I`/`-B`/`__pycache__`
-   handling anywhere. `exec_module` on the pinned helper writes derived `.pyc` the pin never covers;
-   only the `.py` is re-hashed → executed bytecode ≠ pinned-source-hash.
-
-Both break "hashed==executed on the FULL executed closure" on **fidelity** grounds even in a
-non-adversarial fixture. Mos **authorized the bounded repair** (broker `Popen` with strict
-allow-listed `env=` + `-I` + `PYTHON*` stripped; bytecode-cache suppressed via
-`PYTHONDONTWRITEBYTECODE=1`/`-B` + reject stray `__pycache__`/`.pyc` fail-closed before each
-consumer; launcher sibling-import binding to the pinned helper preserved). This **rides the existing
-(ii)-full-closure authorization + R1 + Mos adjudication** — it deepens isolation/binding of an
-already-authorized touch, stays inside the fixture temp root, no fresh Jason owner-window. It is
-**NOT a Case-C escalation** (no probe fired, no evidence produced — a static pre-fire catch, exactly
-what the review gate is for). Added review bars **B7** (broker child env-isolated) and **B8**
-(executed bytecode pinned-or-suppressed) on top of B5+B6+all priors.
-
-**Live target = v8** (env-isolated + bytecode-pinned harness, forthcoming). `f609a449` /
-`2bba933f` / this co-attestation (`e08ad03`) are **SUPERSEDED**. A fresh Mos co-attestation will be
-committed on v8 byte-verify PASS. WI-3 #830 remains HELD at `f4008307`; nothing banked; C-hatch
-armed; NO FIRE.

-
-## Findings — VERDICT: byte-scope + mechanism + hygiene **PASS** (v9 = v7 full-closure + B7 + B8)
-
-The v7→v9 delta is **exactly 22 insertions / 2 deletions**, confined to the intended B7+B8+B6c
-surface; every prior invariant is byte-stable (outside the delta) from the v7 verify.
-
-**B7 — broker child env-ISOLATED (homelab finding 1 CLOSED).** `launch_verified_broker` (`:568`) now
-passes `env=environment` (the strict allow-list, `:570`) — the ambient-`os.environ`-inheritance hole
-is gone — AND runs the broker with `-I` (`:552`, isolated: ignores `PYTHON*`/user-site) + `-B`
-(`:553`). Both children are env-controlled: the launcher was already `env=env` at `PiRpc` (`:53`).
-
-**B8 — executed bytecode PINNED/SUPPRESSED (homelab finding 2 CLOSED).** `reject_pinned_bytecode`
-(`:498`) raises `RuntimeError` fail-closed if a `__pycache__` dir or any `*.pyc` exists in the pinned
-dir, and is called before **each** consumer (launcher `:535`, broker `:562`). Bytecode writes are
-disabled via `PYTHONDONTWRITEBYTECODE=1` (`:729`) in the allow-list env **and** `-B` on both command
-lines. No unpinned `.pyc` can be executed; only the pinned `.py` re-hash governs.
-
-**B6c — launcher sibling-import PRESERVED (v8 regression FIXED).** v8 over-applied `-I` to the
-launcher; on Py3.11+ `-I` implies `-P`, dropping the script dir from `sys.path[0]`, so the pinned
-launcher's bare `from lease_generation import` (launch-runtime.py:15) would `ModuleNotFoundError`. v9
-uses `-s` (`:514`) + `-B` (`:515`) on the launcher (NO `-I`) — neither touches `sys.path[0]`, so the
-sibling import still resolves to `pinned/lease_generation.py`. **Mos empirically re-verified on host
-Py3.11.2** (throwaway, not the harness): `-I` launcher → `ModuleNotFoundError`; `-s`+`PYTHONNOUSERSITE`
-→ import OK. The launcher's env isolation comes from the `PiRpc` `env=` allow-list, NOT `-I`, so
-dropping `-I` does **not** reopen B7. My earlier constraint-(c) assumption ("`-I` does not strip the
-script dir") was FALSIFIED for 3.11+; the author≠reviewer gate (ms-secrev-828) caught it — recorded.
-
-**B5 conjunction (load-bearing repair) — HELD, all three legs (byte-stable from v7):**
-(a) materialized from pinned git-object bytes via `materialize_closure`/`git_object_bytes`, `sha256==pin`

-
-## Independence
-
-Substantive principal-independence of review-v9 is satisfied by an orchestrator-dispatched,
-builder-distinct Opus SECREV (`ms-secrev-828`, byte-only, non-builder, non-Mos). The shared
-`ms-lead-reviewer` git signer on harness+review commits is evidentiary, not substantive — resolved by
-(1) this Mos co-attestation under a **distinct** identity (`mos-orchestrator`) and (2) a homelab
-third-principal verify under its own distinct identity = three distinct-identity principals of record.
-Shared signer = tracked fleet-infra tooling-gap (durable fix = per-lane distinct signers), not a blocker.
-
-## Scope of this record — byte-clear, NOT fire-authorization
-
-Producing probe evidence **executes** the Gate0 mechanism; a byte-clear is not a fire-authorization.
-This clears **bytes / scope / mechanism / hygiene on the v9 (full-closure + B7 + B8) bar**. FIRE
-remains gated on: **homelab third-principal re-verify** (4th round, own distinct identity) + **Mos
-transparency-to-Jason** + **Mos explicit FIRE GO**. Until then: nothing banked, WI-3 #830 held at
-`f4008307` (unmoved), C-hatch armed (materialized-closure rig still no-fire / wrong-value /
-assertion-FAIL / isolation-FAIL → possible Case-C → STOP + escalate to Jason).
-
-**Mos verdict: v9 full-closure + B7 + B8 byte-scope + mechanism + hygiene PASS. Co-attestation of
-record — committed.**
-
----
-
-## ⚠️ SUPERSEDED — homelab v9 4th-round FAIL @1c34e3cb raised a stricter *startup-closure* bar
-
-This co-attestation was **byte-clear on the v9 (env-iso + bytecode-pin) bar ONLY** and self-limited
-above to *"byte-clear NOT fire-authorization; FIRE remains gated on homelab 4th-round re-verify."*
-Homelab (the required third principal) returned **FAIL @1c34e3cb** (static, nothing executed), and Mos
-**UPHELD** it after independently confirming the finding in-source AND empirically on host Py3.11.2 —
-so the v9 byte-clear this document records is **SUPERSEDED** and does **NOT** authorize FIRE.
-
-**Residual startup-closure hole (empirically reproduced by Mos; accepted as gate-STRENGTHENING):**
-neither child carries `-S`, so CPython imports the `site` module **before** the script runs. `-s`
-(launcher) suppresses only *user*-site; `-I` (broker) implies `-s -E -P` but **NOT** `-S`. Proven:
-
-    [-s  -B ]  no_site=0  site_imported=True    ← v9 launcher: site runs
-    [-I  -B ]  no_site=0  site_imported=True    ← v9 broker: -I does NOT imply -S
-    [-s -S -B] no_site=1  site_imported=False   ← v10 launcher fix (sibling import STILL resolves)
-    [-I -S -B] no_site=1  site_imported=False   ← v10 broker fix (additive)
-
-System-site executable `.pth` lines + sitecustomize/usercustomize can therefore run **unpinned startup
-code** before the exact launcher/broker and **outside** `closure_import_guard`, while every hash +
-`reject_pinned_bytecode` + import-guard still pass — defeating hashed==executed on the full *startup*
-closure (strictly wider than the module-import closure v9 cleared). A genuine fidelity hole for a
-fail-closed DO-178C evidence gate.
-
-Mos **authorized the bounded v10 repair**: add `-S` to the **launcher** (keep `-s -B`, NOT `-I`) and
-to the **broker** (keep `-I -B`) — a minimal 2-line delta; no B6c regression (launcher `-s -S -B`
-sibling import empirically intact; `-S` does not touch `sys.path[0]`). Added review bar **B9**
-(no-site startup closure). This **rides the existing (ii)-full-closure authorization + R1 + Mos
-adjudication** (deepens startup-closure isolation of an already-authorized touch, inside the fixture
-temp root, no fresh Jason owner-window) and is **NOT a Case-C escalation** (static pre-fire catch, no
-probe fired). A separate **FIRE-time** constraint is captured: the 3× isolation dispatch must launch
-the runner under externally-enforced `python -I -S -B` (a self-reexec is too late).
-
-**Live target = v10** (no-site harness, forthcoming). `1c34e3cb` / `e1c9a468` / this co-attestation
-(`f320d075`) are **SUPERSEDED**; the prior 2-of-3 (ms-secrev-828 v9 §3 PASS + `f320d075`) does NOT
-carry — all three distinct-identity principals re-verify the new v10 SHA. A fresh Mos co-attestation
-will be committed on v10 byte-verify PASS. WI-3 #830 remains HELD at `f4008307`; nothing banked;
-C-hatch armed (fired-rig only); NO FIRE.

-## Principal-independence attestation (Mos independence ruling — process of record)
-
-This review is produced by a **distinct Opus SECREV session, orchestrator-dispatched** — the **`ms-secrev-828`
-reviewer lane, dispatched by `mosaic-100`** — **byte review only, ran nothing**, and **did NOT build** this harness
-(builder = ms-rev-826). Author ≠ reviewer (Gate-16). This is one of three principals: **Mos commits his own
-distinct-identity byte-scope-verify co-attestation at v-final**, and **homelab's independent verify is the third
-principal**. (The `ms-lead-reviewer` **Git signer identity** shared across published review commits is a git-signer
-question routed to Mos; it does not bear on this lane's process/dispatch independence, attested here.)
-
-## NEW-5 CLOSED — approach (i): exact-byte pin, adjacent re-hash, exec in place
-
-- **Exact-byte sha256 is the trust anchor, NOT substring heuristics.** Launcher bytes are read from the immutable
-  git object (`git show f4008307:<path>`) and gated on `sha256(launcher_bytes) == GATED_LAUNCHER_SHA256`
-  (`e950e422…`) (:354). The `behavior_markers` `in`-checks (:364-372) are explicitly commented "the exact launcher
-  digest above is the trust anchor. These marker checks are diagnostic belt-and-suspenders only, never a substitute
-  for the pin" (:362-363). The old ordered `.find()` heuristic (`register < initialize < execute`, min<0) is **gone**.
-- **Final re-hash immediately adjacent to `Popen`, no interleaved yield.** `launch_verified_pi` assembles `command`,
-  then — as the statement **immediately before** `return PiRpc(command, …)` (which performs the `Popen`) — re-hashes
-  the launcher: `if hashlib.sha256(launcher.read_bytes()).hexdigest() != GATED_LAUNCHER_SHA256: raise` (:411-412),
-  `return PiRpc(...)` (:413). **No harness-controlled step (no `wait_path`, no broker spawn) sits between the re-hash
-  and the exec** — the broker `Popen` + `wait_path` occur *before* `launch_verified_pi` is called (:611-621). Window
-  narrowed to the fork/exec itself.
-- **Exec stays IN PLACE at the pinned f4008307-worktree path.** The precondition returns the worktree paths
-  `gated_root / launcher_relative`, `gated_root / generation_relative` (:378); Pi execs `str(launcher)` = that
-  worktree launch-runtime.py (:390,:621), and the broker `--generation-module` = the worktree lease_generation.py
-  (:614). The reverted (ii) machinery is **gone**: `grep pinned-lease-broker / PYTHONPATH / fixture_launcher /
-  fixture_generation / write_bytes == 0`. Launcher import resolution and the file-backed fidelity surface are
-  therefore **unperturbed** (this is the lower-risk approach Mos mandated over copy-to-fixture).
-
-## NEW-6 CLOSED — portable, validated, off-by-one gone
-
-`GATED_WI_ROOT` is no longer the off-by-one `HERE.parents[3].parent / "stack-cr-wi3-revoke"`. It is resolved by
-`resolve_gated_wi_root()` (:257-307): an explicit `GATED_WI_ROOT` env override, else **repo-relative** `git worktree
-list --porcelain` (from `repository_root()`, first parent containing `.git`) selecting the **unique** worktree whose
-`HEAD == f4008307` **and** `branch == refs/heads/feat/830-compaction-revoke` (raise if ambiguous/absent). It then
-**fail-closes** unless `gated_root.is_dir()`, `git rev-parse --is-inside-work-tree == "true"` (:304-305), and
-`HEAD == GATED_WI_HEAD` (:306-307). Independently recomputed on this host (git query, harness not run): it resolves
-to the real worktree **`/home/hermes/agent-work/stack-cr-wi3-revoke`**. Portable + validated; the off-by-one is gone.
-
-## Full v4/v5 carry-over re-sweep (byte-stable vs `7f975b95` except the NEW-5/6 delta)
-
-`diff 7f975b95 → 2d54a9dd` confines changes to launcher resolution (NEW-6) + adjacent-rehash-exec-in-place (NEW-5);
-nothing else moved. Re-swept intact: **creds-scrub** (`scrub_fixture_credentials` + outermost `finally`); **`source-invalid`
-ABSENT** (grep=0 both files); **fidelity file-backed** unperturbed (broker `read_runtime_generation`/`bump_runtime_generation`
-on the fixture `.state`; `assert_d4` `generation_source=="state-file"` + `state_file_drives_lifecycle` +
-`state_file_in_fixture_root` + `new→MUTATOR_UNVERIFIED`/`prior→STALE_GENERATION`); **`lease_anchor_registered`** INTACT
-(event + `hex-256`); **live-path** gated launcher; **fail-closed precondition**; **fixture-socket isolation**; **`-O`-safe**
-(0 bare `assert`, PASS derived); **allow-list env** (0 `os.environ.copy`); **`--runs choices=(3,)`**; **single p3 broker**
-(broker byte-identical to v5). **ABSENT sweep = 0** (P5/P6/P2-bank/retry-launder/mosaic-yolo/execRuntime/pi_gate0/run_open/
-atomic; extension actions only bump/lifecycle/authorize/promote; no exec-at-import). **Beyond-R1 tripwire: not tripped** —
-exec is in place, imports and the file-backed observation surface untouched; no isolation crossing.
-
-## Verdict
-
-**PASS @ `2d54a9dd`.** NEW-5 (approach (i): exact-byte sha256 pin as trust anchor; adjacent re-hash immediately
-before `Popen` with no interleaved yield; exec in place at the pinned f4008307-worktree path; (ii) copy-to-fixture/
-PYTHONPATH machinery reverted) and NEW-6 (portable, validated, off-by-one-gone root resolution) are both **closed**;
-the full v4/v5 carry-over holds byte-stable except the two intended surfaces; ABSENT sweep is 0; the R1 file-backed
-fidelity surface is unperturbed. Zero out-of-scope surface.
-
-**Findings: none.**
-
-## Scope reminder (not a finding)

-separately gated on Mos's explicit post-clear GO** and is not authorized by this review.

-## Fixture and precondition-path audit
-
-| Harness precondition | Result | Static construction / real closure satisfaction |
-| --- | --- | --- |
-| Fixture broker socket equals `MOSAIC_LEASE_BROKER_SOCKET` | PASS | Harness sets the variable from `socket_path` at `p3_d4_focused_run.py:723` and rejects mismatch at `:452-453`. Launcher consumes that exact variable at `launch-runtime.py:70`; broker accepts the fixture value via `--socket` at `p3_generation_broker.py:46-50` and binds it at `:60-63`. |
-| `MOSAIC_LEASE_GENERATION_FILE` is absent before launcher execution | PASS | The isolated environment dictionary has no such key (`p3_d4_focused_run.py:712-737`) and precondition rejects any inherited value at `:454-455`. The launcher creates and assigns it only after successful registration and initialization (`launch-runtime.py:74-90`, `95-99`). |
-| `HOME` is fixture-relative | PASS | Constructed as `root / "home"` at `p3_d4_focused_run.py:680,713`; validated by the fixture-path loop at `:456-471`. Launcher copies the source environment only after receiving this fixture value (`launch-runtime.py:68,95`). |
-| `XDG_CONFIG_HOME` is fixture-relative | PASS | `root / "config"` at `p3_d4_focused_run.py:681,714`; validated at `:456-471`. |
-| `XDG_CACHE_HOME` is fixture-relative | PASS | `root / "cache"` at `p3_d4_focused_run.py:682,715`; validated at `:456-471`. |
-| `XDG_STATE_HOME` is fixture-relative | PASS | `root / "state"` at `p3_d4_focused_run.py:683,716`; validated at `:456-471`. |
-| `XDG_RUNTIME_DIR` is fixture-relative | PASS | `root / "runtime"` at `p3_d4_focused_run.py:684,717`; validated at `:456-471`. |
-| `TMPDIR` is fixture-relative | PASS | `root / "tmp"` at `p3_d4_focused_run.py:685,718`; validated at `:456-471`. |
-| `D4_PI_LOG` is fixture-relative | PASS | The run creates `root / "pi.jsonl"` at `p3_d4_focused_run.py:758` and assigns it at `:724`; validated at `:456-471`. |
-| `MOSAIC_AGENT_WORKDIR` is fixture-relative | PASS | The run creates `root / "workspace"` at `p3_d4_focused_run.py:755` and assigns it at `:726`; validated at `:456-471`. Launcher executes with the copied fixture environment at `launch-runtime.py:95-101`. |
-| `MOSAIC_HEARTBEAT_RUN_DIR` is fixture-relative | PASS | `root / "heartbeat"` at `p3_d4_focused_run.py:687,727`; validated at `:456-471`. |
-| `MOSAIC_HOME` is fixture-relative | PASS | `root / "mosaic-home"` at `p3_d4_focused_run.py:688,728`; validated at `:456-471`. |
-| Socket parent is this temporary root | PASS | The run derives `socket_path = root / "generation.sock"` at `p3_d4_focused_run.py:757`; precondition requires `socket_path.parent == root` and `root.parent == tempfile.gettempdir()` at `:472-474`. Broker additionally refuses a generation path whose parent differs from `socket_path.parent` at `p3_generation_broker.py:71-75`. |
-| Complete pinned closure can be materialized without an unpinned project import | PASS | `materialize_closure` reads the three exact objects and verifies their hashes (`p3_d4_focused_run.py:397-431`); `closure_import_guard` allows only `lease_generation` as non-stdlib (`:342-371`). Launcher has that sole project import at `launch-runtime.py:15`; broker imports its supplied generation file using an explicit path at `p3_generation_broker.py:29-41`. |
-
-**All remaining preconditions pass against real closure bytes: Y.**
-
-No B5-B9/D4 assertion, closure hash gate, before-exec re-hash, fixture/socket precondition, bytecode rejection, launch/broker flag, or run-count setting was changed by this audit artifact.

-## Independence (GUARD 2 — principal-independence attestation)
-
-Distinct Opus SECREV session, orchestrator-dispatched — the **`ms-secrev-828` reviewer lane, dispatched by
-`mosaic-100`** — **byte review only, ran nothing** (harness/broker not executed); did **not** build this harness
-(builder = ms-rev-826); is not Mos; distinct principal from both. This re-verifies from scratch on the v10 SHA after
-homelab's 4th-round FAIL @`1c34e3cb` (no `-S` → `site` startup-closure hole) superseded my v9 PASS + Mos's co-attest.
-The `-S`/`-s`/`-I` behavior checks below use a *throwaway* script to observe interpreter startup — not the harness.
-
-## ★ B9 — No-site startup closure (the homelab 4th-round FAIL)
-
-The delta vs `1c34e3cb` is **exactly two `-S` insertions**, byte-confirmed by `diff` (nothing else; +28 B fully
-accounted by the two `        "-S",\n` lines):
-
-- **(i) Launcher command** (`launch_verified_pi`, :512-516): `sys.executable, "-s", "-S", "-B", str(launcher), …` —
-  carries `-s` + **`-S`** + `-B`, and **no `-I`**.
-- **(ii) Broker command** (`launch_verified_broker`, :551-554): `sys.executable, "-I", "-S", "-B", str(broker_path), …`
-  — carries `-I` + **`-S`** + `-B`.
-- **(iii) `site` not imported at child startup** — empirically confirmed (Python 3.11.2, throwaway script):
-  `python3 -s -S -B main.py` → `sys.flags.no_site == 1`, `'site' in sys.modules == False`; `python3 -I -S -B main.py`
-  → `no_site == 1`. So system-site `.pth` executable lines and `sitecustomize`/`usercustomize` **cannot run unpinned
-  startup code** before the pinned launcher/broker. (Contrast without `-S`: `python3 -s -B` → `no_site == 0`, `site`
-  imported — the exact v9 hole this closes.)
-- **(iv)** No harness reliance on any site-injected path/hook (env is the constructed allow-list; children execute
-  pinned bytes).
-- **(v) `-S` does not touch `sys.path[0]`** (unlike `-I`/`-P`) — empirically confirmed: `python3 -s -S -B main.py`
-  keeps `sys.path[0]` = the script's directory, so the launcher's bare `from lease_generation import
-  initialize_runtime_generation` (`f4008307:launch-runtime.py:15`) **still binds `pinned/lease_generation.py`** with
-  `-S` present. The broker's explicit `--generation-module` import (via `importlib`) binds the pinned helper
-  regardless of `sys.path`/site, so `-I -S` is correct there.
-- **(vi) Delta = exact 2-line `-S` only** vs `1c34e3cb` (git-diff/byte-compared, not accepted on assertion).
-
-## All prior bars — byte-stable (delta was only the two `-S` lines)
-

-## Independence (GUARD 2 — principal-independence attestation)
-
-This review is produced by a **distinct Opus SECREV session, orchestrator-dispatched — the `ms-secrev-828`
-reviewer lane, dispatched by `mosaic-100`** — **byte review only, ran nothing**, that **did NOT build** this harness
-(builder = ms-rev-826) and **is not Mos**. Three distinct principals: this reviewer, the builder, and Mos (whose
-own distinct-identity byte-scope-verify follows); homelab's independent verify is a further principal — it is
-homelab's third-principal FAIL @`2d54a9dd` (upheld by Mos) that correctly retired the approach-(i) adjacency
-re-hash and authorized this full-closure. v6/`2d54a9dd`/`23c0caca`/`12914d8` are superseded.
-
-## Why v7 (the reopen-after-hash hole)
-
-Approach (i) re-hashed the launcher then let `Popen` **reopen the worktree path** — hashed-snapshot ≠ executed-bytes
-(the worktree file is a shared, same-UID-mutable path). Statement adjacency alone did not bind. v7 closes it for the
-**full project-code closure** (launcher + `lease_generation.py` helper + `p3_generation_broker.py`).
-
-## B5 — HASHED == EXECUTED on the full closure (binding conjunction, stated verbatim)
-
-The reopen-after-hash shape is unavoidable for imported/exec'd files, so closure rests on the **conjunction of all
-three legs**, each byte-verified here:
-
-> **(a)** bytes are materialized **from the pinned git-object @ `f4008307`** (helper/launcher) and **@ `23c0caca`**
-> (broker) — `git show <commit>:<path>`, the trusted immutable object, **never the mutable worktree file**; **AND**
-> **(b)** into a **fixture-private `0o700` dir with `0o600` files created via `O_CREAT|O_EXCL`** — no writer exists in
-> the threat model between hash and exec; **AND** **(c)** each member is **re-hashed == its pin IMMEDIATELY before
-> exec/import, fail-closed (`RuntimeError`)**.
-
-Byte evidence:
-- **(a)** `git_object_bytes(git_root, commit, relative)` = `git show <commit>:<path>` (:322-327); `materialize_closure`
-  reads all three members from git objects and asserts `sha256(data) == digest` else `RuntimeError` (:415-433). Worktree
-  working-tree files are never read.
-- **(b)** `pinned = root / "pinned"; pinned.mkdir(mode=0o700)` (:435-436); `write_pinned_file` uses
-  `os.open(path, O_WRONLY|O_CREAT|O_EXCL|O_CLOEXEC, 0o600)` (:379-382). **No `os.chmod`/`os.rename`/`shutil.move`
-  anywhere** (grep=0); `O_EXCL` refuses a pre-planted file/symlink, so no symlink-follow or hijack gap; the dir is a
-  fresh per-run `mkdtemp` child, owner-only. **No code re-opens the pinned files for write between materialize and
-  consume** — there is no writable window.
-- **(c)** launcher re-hash `sha256(launcher.read_bytes()) == GATED_LAUNCHER_SHA256` is the statement immediately before
-  `return PiRpc(command,…)` (:528-530); broker **and** helper re-hashes (`== GATED_BROKER_SHA256`,
-  `== GATED_GENERATION_SHA256`) are the two statements immediately before `return subprocess.Popen(command,…)`
-  (:546-551). No interleaved harness yield.
-
-Adjacency-only exec-from-worktree is **absent** for every member (all three exec/import from `pinned/`; grep worktree-exec=0).
-
-## B6 — helper + broker pinned and bound to execution (one shared helper)
-
-`materialize_closure` writes exactly **one** `pinned/lease_generation.py` (:442). The broker executes the **pinned**
-broker with `--generation-module = closure.generation` = that pinned helper (`launch_verified_broker`, :533-551, called
-:746-747). The launcher executes the **pinned** launcher (`python3 pinned/launch-runtime.py`), whose
-`import lease_generation` resolves via `sys.path[0]` = the script's own `pinned/` dir to the **same** sibling
-`pinned/lease_generation.py`. Launcher-import and broker-`--generation-module` therefore resolve the **same single
-pinned helper copy**, not two copies and not the worktree. Worktree helper/broker are not re-read at runtime.
-
-**Closure-import guard:** `closure_import_guard` AST-parses each member and refuses any non-stdlib import outside the
-allow-set `{"lease_generation"}` (and any relative import) → `RuntimeError` (:341-364). The 3-member closure is
-therefore provably complete — no unpinned project-code dependency can slip in.
-
-## BAR1 — Traceability
-
-`GATED_WI_HEAD == f4008307`; the precondition asserts `git merge-base --is-ancestor 66b1e0a0 f4008307` (:315-330),
-independently confirmed **YES** — the pinned launcher forward-contains the `66b1e0a0` file-backed generation mechanism.
-
-## BAR2 — Fidelity file-backed, `.state` in fixture root, UNTOUCHED
-
-`pinned/` holds **code bytes only** (launcher/helper/broker). The `.state` generation file is written by the launcher
-to `socket_path.parent` (the fixture root), **not** `pinned/`. The broker (pinned, byte-identical `4db4fef1`) still
-enforces `generation_environment` raising if `state_path.parent != socket_path.parent` (grep=2), and `assert_d4`
-still checks `state_file_source == "state-file"` / `state_file_drives_lifecycle` / `state_file_in_fixture_root` +
-`new→MUTATOR_UNVERIFIED` / `prior→STALE_GENERATION` (grep=4, unchanged). The v7 change did not move `.state` into
-`pinned/` or perturb these asserts.
-
-## BAR3 — Carry-over
-
-(a) **live-path:** Pi launched via `python3 pinned/launch-runtime.py --runtime pi -- pi …` (gated register-before-exec);
-`mosaic yolo`/`execRuntime` = 0. (b) **fail-closed precondition:** `gated_launcher_precondition` (resolve+materialize+
-verify) runs before any launch, fail-closed. (c) **fixture-socket isolation:** `MOSAIC_LEASE_BROKER_SOCKET` = per-run
-fixture socket; single pinned p3 broker serves `register_anchor`; no live/default broker reachable; non-destructive.
-(d) **`lease_anchor_registered` INTACT:** event + `session_id_shape=="hex-256"` unchanged (broker byte-identical);
-`assert_d4` folds it into the single-identity set — not deleted/softened/optional/repointed.
-
-## Re-confirm + ABSENT sweep
-
-Spawns ONLY the single pinned p3 broker; promotion=fixture-only; full D4 asserts; `--runs choices=(3,)`; allow-list
-env (0 `os.environ.copy`); **`-O`-safe** (all new checks `RuntimeError`, **0 bare `assert`**); creds-scrub intact;
-non-destructive (fixture tempdir only); deterministic (git objects + fixed pins); closure-import guard present.
-**ABSENT = 0:** P5/P6/P2-bank/retry-launder/mosaic-yolo/execRuntime/pi_gate0; `source-invalid` grep=0; no live/real-broker
-path; no `.state`/gen path outside the fixture root; no extra broker/socket; no exec-at-import (`__main__`-guarded); no
-adjacency-only exec-from-worktree for any member; the only mechanism change is materialization; no scope-widen.
-
-## Verdict
-
-**PASS @ `f609a449`.** B5 (full-closure hashed==executed via the (a)+(b)+(c) conjunction with no writable window),
-B6 (one shared pinned helper bound to both launcher-import and broker-`--generation-module`; complete closure), BAR1,

-## Independence (GUARD 2 — principal-independence attestation)
-
-Distinct Opus SECREV session, orchestrator-dispatched — the **`ms-secrev-828` reviewer lane, dispatched by
-`mosaic-100`** — **byte review only, ran nothing** (the harness/broker were not executed); did **not** build this
-harness (builder = ms-rev-826); is not Mos. This verdict is my own. (The `-I` semantics check below runs a *throwaway*
-two-line script to observe the interpreter's `sys.path` behavior — it does not run the harness, broker, or any part of
-the reviewed closure.)
-
-## 🔴 BLOCKING FINDING — B6(c) broken: `-I` on the launcher strips the pinned-helper import path
-
-**File:line — `p3_d4_focused_run.py:512`** (the `"-I"` added to `launch_verified_pi`'s launcher command).
-
-The pinned launcher `launch-runtime.py` @`f4008307` imports its helper with a **bare top-level import**:
-`from lease_generation import initialize_runtime_generation` (launcher line 15) — no `sys.path` manipulation. Under
-v7 this bound because `python3 pinned/launch-runtime.py` put the script's directory (`pinned/`) at `sys.path[0]`, so
-the sibling `lease_generation` resolved to `pinned/lease_generation.py`.
-
-v8 now runs the launcher as `python3 -I -B pinned/launch-runtime.py …` (:512-513). **`-I` implies `-P` (Python 3.11+),
-which does NOT prepend the script's directory to `sys.path`.** Empirically confirmed on this host (Python 3.11.2),
-using a throwaway script (not the harness):
-
-```
-python3 -I -B main.py  → sys.path[0] = '/usr/lib/python311.zip'
-                          import sibling → ModuleNotFoundError: No module named '…'
-python3    -B main.py  → sys.path[0] = '<script dir>'  → sibling import: OK
-```
-
-Therefore, at FIRE on Python 3.11+, the launcher's line-15 `from lease_generation import …` raises
-`ModuleNotFoundError` at module load — the pinned helper does **not** resolve (neither pinned nor worktree; the import
-simply fails). **B6(c) — "launcher sibling-import to `pinned/` via `sys.path[0]` STILL BINDS" — does not hold.** The
-build report's assertion "`-I` keeps script dir" is false on 3.11+, and could not have been observed under the
-correct "never run" boundary.
-
-Note: the env allow-list carries no `PYTHONPATH` (correct for B7), and `-I` ignores `PYTHON*` env regardless, so there
-is no alternate resolution path — the launcher import is unrecoverable under `-I`.
-
-**Fix:** remove `-I` from the **launcher** command only (keep `-B` + the `env=` allow-list — the launcher's
-env-isolation is already provided by the constructed allow-list, which contains no `PYTHONPATH`/`PYTHONHOME`/
-`PYTHONPYCACHEPREFIX`, and it needs `pinned/` at `sys.path[0]` for the sibling import). Keep `-I` on the **broker**
-command (it loads the helper by explicit `--generation-module` path via `importlib`, so it never needs the script
-dir on `sys.path`). Alternatively, inject the pinned dir explicitly (e.g. `PYTHONPATH=pinned/` — but that reintroduces
-a `PYTHON*` passthrough B7 forbids, so dropping `-I` on the launcher is the clean fix).
-
-## What DID land correctly (for the author's fast turnaround)
-
-- **B7 — broker child env-isolated: correct.** `launch_verified_broker` now takes `environment` and passes
-  `env=environment` (the constructed allow-list, **not** `os.environ`) to `Popen` (:566-568); the broker command
-  includes `-I` (:551); the allow-list contains no `PYTHONPATH`/`PYTHONHOME`/`PYTHONPYCACHEPREFIX` passthrough. The
-  broker child cannot inherit ambient env or resolve stdlib imports to ambient code. ✅
-- **B8 — bytecode pinned-or-suppressed: correct.** `PYTHONDONTWRITEBYTECODE=1` is in the allow-list env (:728) and
-  `-B` is on **both** child commands (:512-513 launcher, :551-552 broker); `reject_pinned_bytecode` fails closed
-  (`RuntimeError`) on any pre-existing `pinned/__pycache__` or `*.pyc` (:498-501) and is called **before each
-  consumer** (:534 launcher, :561 broker). No unpinned `.pyc` can be executed. ✅
-- **B5 conjunction / B6 single-helper / closure-import-guard / BAR1 / BAR2 (`.state` fidelity untouched) / BAR3
-  (live-path, fail-closed precondition, fixture-socket isolation, `lease_anchor_registered` + hex-256) / single p3
-  broker / `-O`-safe / allow-list env / `--runs==(3,)` / ABSENT sweep:** all intact/unperturbed (the delta touches only
-  the env/`-I`/`-B`/bytecode-reject surfaces). These are **not** the failing item.
-
-## Verdict
-
-**FAIL @ `a92ad090`.** B7 (broker env isolation) and B8 (bytecode pinned-or-suppressed) are correctly implemented,
-but the `-I` added to the **launcher** command breaks B6(c): the launcher's bare `from lease_generation import` at
-`f4008307:launch-runtime.py:15` cannot resolve the pinned helper because `-I`/`-P` strips `sys.path[0]` on Python
-3.11+ (empirically confirmed, 3.11.2 → `ModuleNotFoundError`). PASS requires **all** of B7+B8+B5+B6+BAR1/2/3; B6(c)
-does not hold. Not softened → returns to author (ms-rev-826). The fix is narrow: drop `-I` from the launcher command
-(retain `-B` + allow-list env), keep `-I` on the broker.
-
-**Findings:** B6(c) — `p3_d4_focused_run.py:512` (`-I` on the launcher command; breaks the pinned-helper sibling

-top-level `from lease_generation import initialize_runtime_generation` (`f4008307:launch-runtime.py:15`, no `sys.path`
-manipulation) resolves to the **pinned** `pinned/lease_generation.py` — not the worktree, not a miss. **B6(c) holds.**
-
-## B7 — Broker env-isolation (still holds)
-
-`launch_verified_broker` passes `env=environment` (the constructed allow-list, **not** `os.environ`; contains no
-`PYTHONPATH`/`PYTHONHOME`/`PYTHONPYCACHEPREFIX`) to `Popen` (`:570`), and the broker command includes `-I` (`:552`).
-The broker imports the helper by explicit `--generation-module` path via `importlib`, so it never needs `sys.path[0]`
-— `-I` is correct there and does not affect it. (The env's `PYTHONNOUSERSITE`/`PYTHONDONTWRITEBYTECODE` are hardening
-flags, not path/home passthrough, and `-I` ignores all `PYTHON*` env anyway.)
-
-## B8 — Bytecode pinned-or-suppressed (still holds)
-
-`PYTHONDONTWRITEBYTECODE=1` (`:729`) and `PYTHONNOUSERSITE=1` (`:730`) in the allow-list env; `-B` on **both** child
-commands (`:515` launcher, `:553` broker); `reject_pinned_bytecode` fails closed (`RuntimeError`) on any pre-existing
-`pinned/__pycache__` or `*.pyc` (`:498-501`) and is called **before each consumer** (`:535` launcher, `:562` broker).
-No unpinned `.pyc` can be executed.
-
-## B5 — 3-leg conjunction (still holds)
-
-`materialize_closure` reads launcher+helper+broker from **git-object bytes** (`git show <commit>:<path>`) and asserts
-`sha256 == pin` for each, fail-closed; `pinned/` is a fixture-private `0o700` dir inside the per-run fixture temp root;
-files created `O_WRONLY|O_CREAT|O_EXCL|O_CLOEXEC 0o600` (no chmod/rename/symlink gap → no writable window); each member
-re-hashed `== pin` immediately before its `Popen` (launcher; broker + helper). Launcher and broker consume the **same
-single** pinned helper. `closure_import_guard` AST-rejects any unpinned non-stdlib import.
-
-## Fidelity + traceability + carry-over (still hold)
-
-`GATED_WI_HEAD == f4008307` + `merge-base --is-ancestor 66b1e0a0 f4008307` (forward-contains). Extension bumps
-`generation-{sid}.state` via `MOSAIC_LEASE_GENERATION_FILE` (not in-mem); broker reads via `read_runtime_generation`;
-`assert_d4` observes the file-backed transition (`generation_source=="state-file"`, `state_file_drives_lifecycle`,
-`state_file_in_fixture_root`, new→`MUTATOR_UNVERIFIED`, prior→`STALE_GENERATION`); `.state` stays in the fixture temp
-root. `lease_anchor_registered` INTACT (event + `session_id_shape=="hex-256"`). LIVE-PATH drives the pinned gated
-launcher (no released `mosaic`/`execRuntime`). Fail-closed precondition before any launch. Single pinned p3 broker.
-Promotion=fixture-only. `--runs choices=(3,)`. `copy2` = creds-only. Allow-list env (0 `os.environ.copy`).
-
-## ABSENT sweep
-
-P5/P6/P2-bank/retry-launder/mosaic-yolo/execRuntime = 0; `source-invalid` = 0; no live/real-broker path; no `.state`
-outside the fixture root; no exec-at-import (`__main__`-guarded); no adjacency-only-exec-from-worktree; the only change
-is the authorized launcher-flag isolation fix (no mechanism change, no scope-widen); **`-O`-safe** (0 bare `assert`).
-
-## Verdict
-
-**PASS @ `1c34e3cb`.** The v8 FAIL is remediated by the narrow fix (launcher `-I` → `-s` + `PYTHONNOUSERSITE=1`),
-empirically verified to preserve `sys.path[0]=pinned/` so the pinned launcher's sibling import binds to the pinned
-helper; the broker retains `-I` (explicit-path import). B7, B8, B5, B6-rest, fidelity, traceability, and all carry-over
-bars remain intact; zero out-of-scope surface. **Findings: none.**

+# Fleet Configuration Management
+
+This book documents the local roster-v2 desired-state control plane delivered under issue #758. The normative requirements are the [FCM section of the repository PRD](../PRD.md#fleet-declarative-configuration-management-workstream-fcm-758), not the older fleet-suite or observability planning pages.
+
+## Authority boundary
+
+<MOSAIC_HOME>/fleet/roster.yaml is the sole writable desired-state authority for local fleet membership, launch policy, and persisted lifecycle. Generated environment files, systemd enablement, tmux sessions, heartbeat files, and status output are derived or observed. Rebuild projections from the roster; never edit them as desired state.
+
+This control plane is local tmux/systemd only. Remote/SSH entries and connectors are inventory, not reconciliation targets. Arbitrary commands, channels, secret references, gateway catalog convergence, and UI configuration storage are outside this workstream. `mos-comms` is temporary transport glue, not permanent fleet architecture.
+
+## Choose the right workflow
+
+1. **Need to inspect intent?** Read the roster and use mosaic fleet get; see [desired versus observed state](concepts/desired-vs-observed-state.md).
+2. **Need to inspect reality?** Use `status` or `doctor`; use `verify` for a strict non-zero drift/ownership gate. These commands do not repair anything.
+3. **Need to change membership or persisted policy?** Use generation-guarded `plan`, `create`, `update`, or `delete`; see [safe CRUD](how-to/create-update-delete-agent.md).
+4. **Need a one-time runtime action?** Use `start`, `stop`, or `restart`. These do not change persisted desired state.
+5. **Need convergence?** Review apply --dry-run, resolve blockers, then use `apply` with the same current generation; see [reconcile and recover](operations/reconcile-and-recover.md).
+6. **Need v1 migration evidence?** Use preview only. Cutover, canary, and rollback remain held for FCM-M4-002.
+7. **Need the gateway-backed agent catalog?** That is the separate mosaic agent surface, not local fleet desired state.

+# Desired, Derived, and Observed Fleet State
+
+## One writable authority
+
+The canonical local v2 roster at <MOSAIC_HOME>/fleet/roster.yaml is desired state. Membership, stable identity, class, runtime/provider/model selection, launch policy, enablement, and persisted `running`/`stopped` intent are written only through generation-guarded roster mutations.
+
+Derived projections are reproducible consequences of that authority:
+
+- <name>.env.generated;
+- exact roster-named tmux sessions on the configured socket after reconciliation;
+- systemd service targets managed by installation/reconciliation.
+
+Current systemd unit enablement is not yet lifecycle-conformant at boot: installation can enable every
+agent unit, and the launcher projection does not carry `enabled` or `desired_state`. Therefore reboot
+preservation for stopped/disabled agents remains an FCM-M3-002 acceptance hold, not a guaranteed
+projection behavior.
+
+Observed evidence available to current roster-v2 status commands includes systemd active state, tmux
+presence, holder ownership, and unmanaged sessions. Heartbeat files are observational in the wider fleet,
+but roster-v2 `status`, `doctor`, and `verify` do not currently read them. Observation never writes back
+to the roster.
+
+## Generation and ownership
+
+`generation` is a positive integer concurrency fence. A mutating request must provide the current value. Successful changed CRUD increments it exactly once; stale or concurrent writers fail before mutation. Apply/reconcile rereads the canonical roster under a private exclusive lock and uses only that generation and content for effects.
+
+Ownership is exact, never fuzzy. Reconciliation is limited to roster names, the configured socket, the exact holder session, a private installation identity, and private managed paths. An ownership mismatch, unmanaged session, unsafe path, stale generation, or ambiguous lock fails closed.
+
+## Drift decisions
+
+| Observation                              | Interpretation           | Safe response                                                          |
+| ---------------------------------------- | ------------------------ | ---------------------------------------------------------------------- |
+| Generated file differs or is missing     | Derived projection drift | Review apply --dry-run; regenerate from the roster.                    |
+| Desired `running`, exact session missing | `missing-session`        | Diagnose ownership/runtime, then reconcile if safe.                    |
+| Desired `stopped`, exact session present | `unexpected-session`     | Inspect; reconciliation may stop only the proven roster target.        |
+| Disabled agent running                   | `disabled-running`       | Inspect; disabled state wins during explicit safe reconciliation.      |
+| Unknown session on the configured socket | Unmanaged state          | Report only. Do not adopt, rename, or kill it.                         |
+| Heartbeat stale in the wider fleet       | Liveness evidence        | Diagnose separately; current roster-v2 status does not read heartbeat. |
+
+`status` and `doctor` classify. `verify` is also observational but exits non-zero when ownership, drift, or unmanaged-state checks fail. `plan`/apply --dry-run validates proposed projection and lifecycle work without mutation. `apply` and `reconcile` converge only after all preconditions pass.
+
+A partial projection failure does not roll the roster back. Treat the committed roster as authority and regenerate. A lifecycle failure after projection completion preserves both roster and projections for inspection. Sensitive legacy values are never printed; diagnostics are bounded to stable codes, key names where applicable, and hashes.

+Tess and Ultron are conventional instance/display names only. They are not products, required machine identities, role aliases, or authority-bearing classes. A configurable interaction instance uses class: interaction; a configurable validation instance uses class: validator. Any stable name and alias satisfying the structural contract may be used.
+
+Class aliases are deliberately narrow: implementer → code, reviewer → review, and operator-interaction → interaction. No runtime, provider, model, persona prose, or instance name changes this mapping. See [role classes](../reference/role-classes.md) and the [validated generic example](../examples/roster-v2.yaml).
+
+Roster v2 is local-only. It contains no host/SSH placement, connector, channel, secret-reference, arbitrary-command, per-agent socket, or gateway mapping fields. Those concerns require separate requirements and threat models.

+# Fleet Role Authority and Leases
+
+Role content describes behavior; protected authority is immutable code metadata derived only from the canonical class.
+
+## Required workstream classes
+
+`code`, `review`, `validator`, `orchestrator`, `team-leader`, `enhancer`, and `interaction` are required FCM classes. `merge-gate` is additionally protected because it remains the sole approve-to-land and merge authority.
+
+| Class                                        | Authority                                         | Boundary                                                                               |

+| `team-leader`                                | Use explicitly leased capacity                    | Cannot issue leases or mutate roster, credentials, topology authority, or merge state. |
+| `interaction`                                | Receive requests and report status                | Cannot orchestrate, issue leases, mutate configuration, or merge.                      |
+| `code`, `review`, `enhancer`, custom classes | No protected authority by default                 | Persona prose cannot grant protected powers.                                           |
+
+A lease is capacity authorization from an orchestrator, not ownership. It must identify a bounded task or period and does not alter the leased agent's roster identity, role contract, credentials, authority, or persisted lifecycle. Expiry/revocation returns capacity; it does not rewrite the roster.
+
+Semantic validation rejects protected class/tool-policy mismatch in either direction. An instance named Ultron with class: validator remains validation-only. An instance named Tess with class: interaction remains request/status-only. Renaming either instance changes no authority.

+# Configure an Interaction Instance
+
+An interaction instance is a configurable local roster member with canonical class: interaction and matching tool_policy: interaction. “Tess” may be used as a display alias, but neither that alias nor the stable name is required or authority-bearing.
+
+Use the [validated generic roster](../examples/roster-v2.yaml) as the safe shape. Choose a unique stable `name`, any descriptive `alias`, a supported declared runtime, explicit provider/model/reasoning, and a safe work directory. Start with:
+
+```yaml
+name: interaction-example
+alias: Interaction Example
+class: interaction
+tool_policy: interaction
+lifecycle:
+  enabled: true
+  desired_state: stopped
+```
+
+Plan the complete agent payload with the current roster generation, then create it without `--persisted-start`. Creation defaults to enabled/stopped and performs no runtime action. Review the resulting roster and projection plan before any later lifecycle decision.
+
+The interaction class is request/status only. It cannot orchestrate, issue leases, mutate the roster/configuration, grant credentials, certify validation, approve landing, or merge. Connector and channel configuration are outside roster v2; do not add connector, channel, secret, command, remote-host, or gateway fields.

+`validator` may issue independent validation evidence or a certificate. It has no approve-to-land or merge authority. `merge-gate` remains the sole protected merge authority, and changing the validator's name, alias, persona prose, runtime, provider, model, or tool-policy text cannot elevate it.
+
+Certificate consumption and final release evidence remain FCM-M5-002 gates. This page does not create a certificate or authorize merge. See [safe CRUD](create-update-delete-agent.md) and [role authority](../concepts/role-authority-and-leases.md).

 The reconciler uses the exact roster tmux socket, exact holder session, private installation holder identity, and the complete expected global environment. For mutations it acquires its exclusive lock before rereading the canonical roster and fencing its generation; only that under-lock roster drives validation, planning, projections, and lifecycle effects. Before effects, its exclusive lock proves real private `MOSAIC_HOME` and `fleet` ancestors, uses a private `0600` lock leaf, and binds cleanup to the created file identity and ownership token. A fake holder, contaminated global environment, missing identity, unsafe lock path, or unmanaged session fails closed. It does not adopt, kill, or rename any unproven session.

-`migrate-v1 preview` is non-mutating: it emits value-free v1 inventory, a canonical semantically
+`get` is the read/show operation for one v2 agent. Full roster parsing and semantic validation occur on every v2 mutation/reconcile path; there is no separate mutable “config store.” The executable JSON Schema and validated example provide offline structural evidence. The PRD requires an explicit programmatic mosaic fleet validate operation, but the current CLI does not expose one; do not substitute another command or claim that requirement is delivered. This remains an implementation gap for #758.
-validated v2 candidate when ready, sanitized environment dispositions, and non-executable recovery
-evidence. It has no write, apply, canary, or rollback option. Missing preview inputs also return one stable
-blocked JSON object and a non-zero exit, rather than Commander text. See
-[the migration preview contract](../migration/v1-to-v2.md).
 
-`apply` and `reconcile` use roster desired state. `start`, `stop`, and `restart` are exact local one-shot lifecycle effects and never persist a desired-state edit. `status`, `verify`, and `doctor` are observational.
+## JSON and exit behavior
 
-Commands emit one JSON object. Handled precondition errors emit `{ "error": { "code": "..." } }` and exit non-zero. Partial derived/lifecycle effects use explicit `authoritativeRoster`, `projections`, `lifecycle`, and bounded `recovery` fields; they never claim rollback. Any additive `cleanup` diagnostic also exits non-zero, even where known effects are complete: it is not a clean completion and the lock requires inspection before retry.
+Roster-v2 CRUD and reconciler precondition failures emit { "error": { "code": "..." } } and exit non-zero. Migration preview has its own result envelope: a non-ready preview emits { "status": "blocked", "blockers": [...] } and exits non-zero rather than using the CRUD/reconciler error object. Use both exit status and command-specific state fields. A partial reconciliation result distinguishes `authoritativeRoster`, `projections`, `lifecycle`, `recovery`, and optional `cleanup`; it never claims automatic rollback. `verify` exits non-zero for drift, ownership failure, or unmanaged sessions. Sensitive legacy values, credentials, and rejected command text are never printed.
 
-This control plane is separate from the gateway-backed `mosaic agent` catalog. It is local-only and rejects remote/connector lifecycle mutation, arbitrary command/channel/secret input, and unproven tmux ownership.
+## Compatibility and scope
+
+Roster-v1 initialization, provisioning, profiles/personas, and historical fleet add/remove remain compatibility surfaces, not roster-v2 CRUD aliases. New v2 automation should use the table above. migrate-v1 preview writes nothing and has no cutover, canary, or rollback option.
+
+mosaic agent is a separate catalog/transport surface; it does not own <MOSAIC_HOME>/fleet/roster.yaml desired state. Remote/SSH reconciliation, connector mutation, arbitrary commands/channels, secret references, and gateway convergence are rejected or outside scope.

-A stopped roster agent is never started by `apply` or `reconcile`. Direct lifecycle commands are explicit one-shot actions and do not change persisted desired state. Use roster CRUD with the explicit persisted-start option to change that desired state.
+Explicit apply/reconcile never starts a stopped roster agent. Direct lifecycle commands are explicit one-shot actions and do not persist intent. The current update operation preserves `existing.lifecycle`; there is no delivered generation-guarded CRUD operation for changing durable lifecycle after creation. Reboot preservation for stopped/disabled agents is not yet guaranteed because current enabled units and launcher projections do not carry the persisted lifecycle fence; that acceptance evidence remains FCM-M3-002.
 
-All mutations require `--expected-generation <n>` and acquire one private roster-adjacent reconciliation lock before projection or lifecycle effects. Missing or stale generations and concurrent writers fail before effects; the lock is released after success, partial failure, or thrown lifecycle failure. Stale, ownership, unmanaged-session, unsupported-runtime, path, projection, and lifecycle-precondition failures return stable redacted JSON errors and a non-zero exit. No command targets a fuzzy tmux name, arbitrary socket, arbitrary command, channel, secret, or generated file as authority.
+Missing/stale generation, concurrent writer, unsafe path, ownership mismatch, unmanaged session, unsupported runtime, invalid projection, and lifecycle precondition failures return stable redacted JSON and non-zero status.

+mosaic fleet status [<name>], `verify`, and `doctor` are observational roster-v2 commands. They emit one JSON result and do not write projections, mutate desired state, operate lifecycle, or change tmux.
 
-The report distinguishes:
+## State dimensions
 
-- `missing-session`: an enabled agent desired `running` has no exact roster-named tmux session.
+- **Desired:** roster membership, generation, enabled flag, and persisted running/stopped target.
-- `unexpected-session`: a desired-`stopped` agent still has its exact session.
+- **Managed/derived:** generated environment and expected exact service/session topology.
-- `disabled-running`: a disabled roster agent has its exact session.
+- **Observed by current roster-v2 commands:** systemd active state, tmux presence, exact holder ownership, and unmanaged sessions.
-- `unmanagedSessions`: sessions on the configured named socket that are neither the exact holder nor an exact roster agent.
-- `holder`: `owned`, `missing`, or `ownership-mismatch` after exact holder, private install identity, and complete global tmux environment validation.
 
-`doctor` and `status` classify rather than adopt, destroy, or repair unmanaged state. `verify` is observational too, but exits non-zero if ownership cannot be proven, unmanaged sessions exist, or drift is present. Reconciliation fails closed under those conditions and never kills or adopts an unmanaged session.
+Implemented drift classifications include:
+
+- `missing-session`: enabled/desired-running agent lacks its exact session;
+- `unexpected-session`: desired-stopped agent has its exact session;
+- `disabled-running`: disabled roster agent has its exact session;
+- `unmanagedSessions`: named-socket sessions that are neither exact holder nor roster agent;
+- `holder`: `owned`, `missing`, or `ownership-mismatch` after private identity and global environment checks.
+
+Generated projection failures/staleness are surfaced by plan/apply preparation and bounded recovery fields rather than adopted as configuration. Heartbeat remains wider-fleet observational evidence, never desired state, but the current roster-v2 `status`, `doctor`, and `verify` commands do not read heartbeat files. A provable removed-agent projection may be treated as stale derived state during deletion, but general projection-orphan classification and installed source-versus-asset revision mismatch remain FCM-M4-002/M5-002 holds; current commands must not claim those future checks.

+# Lease broker operations
+
+Place the socket and state file in a dedicated directory with mode `0700`. Start the packaged daemon with:
+
+```bash
+python3 "$MOSAIC_HOME/tools/lease-broker/daemon.py" \
+  --socket /run/user/1000/mosaic-lease/broker.sock \
+  --state /run/user/1000/mosaic-lease/state.json
+```
+
+The broker refuses an existing parent directory whose mode is not exactly `0700`, an existing state file not at `0600`, corrupt/incompatible state, or an already-existing socket path. After bind it sets the socket to `0600`. It never silently unlinks a pre-existing socket. On normal termination it unlinks only the socket inode it created, so it does not remove a replacement path.
+
+Before launching Claude, Claudex, or Pi, export the socket path; `mosaic` then runs the runtime through the packaged register-and-exec wrapper:
+
+```bash
+export MOSAIC_LEASE_BROKER_SOCKET=/run/user/1000/mosaic-lease/broker.sock
+mosaic claude # or: mosaic claudex, mosaic yolo claudex, mosaic pi
+```
+
+The wrapper obtains a broker-minted session ID, creates a private `generation-<session>.state` file beside the socket, and `exec`s the runtime without changing its PID/starttime anchor. The all-tools Claude `PreToolUse` hook and Pi `tool_call` handler inherit that identity and read the current generation from the file. Claudex retains its isolated proxy environment and config directory; Mosaic merges the mandatory all-tools and compaction-lifecycle hooks into that isolated `settings.json` before invoking the same wrapper. PRDY init/update, QA remediation, coord, orchestrator, and fleet launchers also converge on this boundary. Broker registration failure, unsafe isolated settings, unsafe generation state, or missing identity denies launch/tool execution fail-closed; broker timeout/unavailability and malformed replies also block tools.
+
+Claude `PreCompact` and `SessionStart(compact)` hooks and Pi pre-/post-compaction handlers invoke `revoke-lease.py`. Pi `session_start` reload/new/resume/fork and Claude resume/clear advance the locked generation before revocation, so a replacement session inherits no lease even when PID/starttime stay unchanged. Do not invoke the revoker manually as a way to restore authority; it only removes authority. If a lifecycle hook reports failure, stop consequential work and repair broker/generation-state availability before re-verification.
+
+Run the permanent launch inventory locally with:
+
+```bash
+python3 packages/mosaic/framework/tools/lease-broker/check-runtime-launches.py --root .
+```
+
+The same check runs in the Mosaic package test suite and therefore in root CI. Any direct Claude/Pi binary launch must be replaced with `launch-runtime.py`, `execLeaseGatedRuntime`, or the gated `mosaic` runtime command; do not add static allowlist exceptions.
+
+Clients must complete the request boundary before waiting for a reply. After sending the single JSON object and its terminating newline, the client **MUST half-close the socket's write side** (`shutdown(SHUT_WR)` in POSIX clients; `socket.end()` in Node) and only then await the response. Merely calling `write()` and waiting is invalid: the broker waits for EOF to enforce the exact-one-frame contract and fails closed at its one-second deadline. Do not replace `end()` with `write()` in client helpers. A delayed second frame remains malformed and is rejected.
+
+`mosaic_context_recover` is the only unverified mutator class. Its durable `mosaic-context-refresh` skill is a thin wrapper over `tools/lease-broker/recover-context.py`: `begin` has the broker rebuild the validated `B_payload`/`H_payload`, revoke first, and mint a new `PENDING_DELIVERY` receipt challenge; `complete` accepts neither receipt text nor a challenge argument. Claude maps only the exact direct recovery executable/validated arguments to this exempt tool identity; ordinary `Bash` remains gated. Pi exposes only the `mosaic_context_recover` custom tool; ordinary `bash` and all other tools remain gated. A normal-path receipt cannot be replayed through recovery because each retry begins a distinct recovery cycle and recovery completion cannot receive caller-presented evidence.
+
+Production daemon startup creates a separate private observer socket unless a test-only `--test-observer-file` fixture is selected. Claude's Stop hook sends its exact latest assistant entry and Pi's `message_end` handler sends only finalized assistant content to that authenticated transport; the broker public socket never accepts message text. This is byte-build and private out-of-process harness wiring only: do not activate it against a live daemon, live socket, systemd service, tmux session, or model-output stream outside the controlled integration procedure.
+
+Receipt honesty is load-bearing: absent, malformed, prefix-truncated, and observable adapter-mutated terminal receipts do not promote. A tail-only case is non-promoting only where the concrete terminal payload is malformed or observably incomplete. A tail-preserving middle drop is **not receipt-detectable**; it is the disclosed T-C injection-contract residual deferred to WI-7 server-side evidence. The receipt remains a T-A delivery/liveness prerequisite, never a safety, obedience, or residency proof. The framework skill is source-resident and bridge-projected on install/upgrade; do not hand-create a live runtime symlink.
+
+After a runtime exits, its `generation-<session>.state` file may be removed only after verifying that no process for that broker-minted session remains; stale files carry no lease authority but should be retained during incident analysis. After a broker crash, preserve the protected state file and restart only after verifying that no broker owns the socket. Restart intentionally clears all volatile VERIFIED leases. A leftover socket requires an operator to verify the owning service is stopped and remove that exact socket deliberately. Corrupt, oversized, symlinked, or non-regular state fails closed; do not overwrite it. Preserve it for incident review and establish new state only through an explicit operational decision, which invalidates prior sessions and tokens.
+
+## Security posture
+
+Directory `0700` plus socket/state `0600` is built-in same-principal hardening only: it excludes other UIDs but does **not** stop the same UID from unlinking and counterfeiting the socket. It therefore does not close T-C same-UID replacement. WI-1 does not provide a distinct-principal boundary. A stronger distinct-principal deployment requires an external protected proxy, ACL, or service boundary that clients cannot unlink or rebind and that preserves the authenticated client identity required by the broker's `SO_PEERCRED` and ancestry checks. Server-side branch protection remains the irreducible backstop.

+# FCM-M5-001 Fleet Documentation Deferrals and Holds
+
+**Issue:** #758 · **Branch:** `docs/758-fleet-config-operator-docs`
+
+These are accepted existing DAG boundaries, not omissions silently claimed as delivered.
+
+## FCM-M3-002 hold
+
+- Boot/reboot preservation for roster members persisted stopped or disabled.
+- Current installation may enable all agent units, while the launcher projection does not yet carry
+  `lifecycle.enabled` or `desired_state`; documentation therefore does not claim lifecycle-safe reboot.
+- Heartbeat/liveness integration into roster-v2 `status`, `doctor`, and `verify`; current observations
+  cover systemd active state, tmux sessions, holder ownership, and unmanaged sessions only.
+
+## FCM-M4-002 hold
+
+- Executable v1-to-v2 cutover, reversible canary, and rollback.
+- Stale-projection/orphan migration classification and current-host managed/unmanaged fixture coverage.
+- Any live migration, lifecycle, systemd/tmux/session, or rollback action.
+
+M5 docs describe prerequisites and the preview boundary only. A ready preview is not migration or rollback evidence.
+
+## Explicit validate-operation gap
+
+- `FCM-REQ-03` requires a documented programmatic `mosaic fleet validate` operation.
+- The current CLI does not expose that operation. Existing mutation/reconcile validation and the
+  documentation example test are not a replacement for the missing command.
+- FCM-M5-001 documents this implementation gap without inventing syntax, JSON, exit behavior, or an
+  owning implementation card. Parent #758 must remain open until the requirement is implemented and
+  evidenced or the PRD/DAG is explicitly revised through the authoritative process.
+
+## FCM-M5-002 hold
+
+- Deterministic source-versus-installed asset revision detection and safe refresh implementation.
+- Rolling local canary, independent validator certificate, final release evidence, merge-gate approval, and parent #758 closure.
+
+`operations/upgrade-assets.md` is therefore a fail-closed hold, not an invented procedure.
+
+## Compatibility interpretation
+
+The M0 cross-cutting row requiring every retained/migrated artifact to validate through the executable contract is satisfied by each artifact's declared executable disposition, not by forcing versioned v1 fixtures through the v2 parser:
+
+- retained examples are explicit `version: 1` fixtures validated by the production v1 parser;
+- canonical profiles validate through the shared baseline plus `roles.local` resolver;
+- the service preset validates through its production service-policy reader;
+- migration candidates validate through the production v2 compiler and shared semantic resolver.
+
+The executable disposition inventory rejects undeclared additions/removals and prevents silent legacy drift.
+
+## Repository-wide documentation structure
+
+The accepted #758 IA is the domain book under `docs/fleet/`. Creating global `USER-GUIDE`, `ADMIN-GUIDE`, or `DEVELOPER-GUIDE` books and cleaning unrelated pre-existing `docs/` root files are outside this bounded card. The repository sitemap links the fleet book. No HTTP/API/auth contract changed, so OpenAPI and endpoint-index updates are not applicable.
+
+Canonical documentation remains in-repository; no external publishing or generated publishing output is in scope. Parent issue #758 stays open through M5.

+# Issue #812 — durable Gitea PR review comments
+
+- **Lane:** ms-812
+- **Branch:** `fix/812-pr-review-comment`
+- **Issue:** mosaicstack/stack#812
+- **Budget:** 15K working estimate; single focused shell-wrapper/test/docs change.
+
+## Objective
+
+Make the Gitea `comment` action in `packages/mosaic/framework/tools/git/pr-review.sh` use the supported Gitea comments REST API and report success only after provider read-back verifies the created comment against the intended repository, PR, and exact body.
+
+## Plan
+
+1. Add and commit a failing shell regression harness before production changes.
+2. Verify RED against the nonexistent `tea pr comment` fallback false-positive.
+3. Implement the minimal supported write plus ID-based provider read-back.
+4. Document that wrapper write output is not durable provenance until read-back succeeds.
+5. Run focused regression tests, touched-package tests, and repository quality gates.
+6. Remediate review findings, queue-guard, and push for coordinator-owned independent review. Do not open or merge a PR.
+
+## Progress checkpoints
+
+- [x] RED regression committed and reported to mosaic-100 (rebased commit `770e3f57`)
+- [x] Initial minimal fix implemented (rebased commit `ea7f8c57`)
+- [x] Rebased cleanly onto main `627cf2bb387f7c84a532d88819903a7679ce0d72`
+- [x] Codex blocker remediated by replacing unsupported `tea api` with authenticated REST write/read-back
+- [x] Focused, package, and repository gates green
+- [ ] Coordinator-owned independent review pending after push
+- [x] No PR opened; no self-review or self-merge
+
+## Tests run
+
+- RED after rebase: the regression harness failed against `origin/main` with status 1 after reproducing the old `tea pr comment` zero-exit fallback and false success echo.
+- GREEN at resumed head: the same harness passed with REST POST 201 plus GET 200 read-back.
+- All `packages/mosaic/framework/tools/git/test-*.sh` harnesses passed.
+- `shellcheck -x` passed for the changed scripts; `bash -n` passed.
+- Manifest resolver returned `framework` for `tools/git/test-pr-review-gitea-comment.sh`.
+- `pnpm test` passed (43/43 Turbo tasks; Mosaic 75 files/1434 tests; Gateway 56 files/628 tests plus documented skips).
+- `pnpm typecheck` passed (42/42 tasks), `pnpm lint` passed (23/23), and `pnpm format:check` passed.
+- Firewall checks found no user-home paths or operator identities in changed shipped files; no token value is logged or echoed.
+
+## Risks / blockers
+
+- No active implementation blocker. #789 reached terminal merged state and the coordination hold was lifted.
+- Review round 1 found one portability blocker: the API base reconstructed `https://$host` and discarded configured schemes/path prefixes.
+- Review round 2 found a second subpath portability blocker: clone-derived `get_repo_slug` retained the deployment prefix, duplicating it under `/api/v1/repos/`.
+- Round 3 resolves owner/repo relative to the configured Gitea base path for HTTP(S) clones while preserving root-mounted and SSH clone forms. Host matching now compares non-default ports consistently.
+- REST transport failures, non-201 writes, malformed/missing created IDs, non-200 read-backs, and read-back mismatches all fail closed.
+- Existing approve/request-changes behavior remains covered.
+- Independent exact-head re-review remains coordinator-owned.
+
+## Final verification evidence
+
+- URL-portability regression was RED before remediation at the new `http://git.mosaicstack.dev` case and GREEN afterward.
+- Round-3 genuine subpath regression was RED against round-2 head `1b190201` and GREEN after the fix: `https://git.example/gitea/owner/repo.git` maps to API repository `owner/repo` under configured base `/gitea`.
+- Regression coverage verifies POST and read-back GET for root-mounted HTTP(S), path-prefixed HTTP(S), non-default HTTP port, scp-style SSH, and `ssh://` clone forms.
+- Focused shell checks, all git-wrapper harnesses, and full repository test/typecheck/lint/format gates passed after remediation.
+- Branch will be force-pushed with lease for coordinator re-verification; no PR opened.

+# WI-1 Scratchpad — Authenticated external lease broker
+
+- **Issue:** Gitea #828
+- **Milestone:** 188 — Compaction-Refresh Mechanism (M1: Claude + Pi)
+- **Branch:** `feat/828-lease-broker`
+- **Starting HEAD:** `d801d6c4c8a984d6a95033c49714210018d3d9a8`
+- **Session role:** Orchestrator coordinating implementation; Mos retains merge authority.
+
+## Objective
+
+Implement the ratified WI-1 product lease broker under `packages/mosaic/`: Linux `SO_PEERCRED` identity, broker-minted logical session IDs, `(pid,starttime)` launcher anchors with per-hop `/proc` starttime revalidation, sibling-substitution rejection, same-PID runtime-generation revocation, crypto-RNG single-use token persistence, and protected Unix-socket posture.
+
+## Authority verification
+
+Verified before code on session start; all exact SHA-256 values matched:
+
+- BUILD-BRIEF: `89fdbc27ed0e5050dc7b52f3ef2ddaea691edf17fd89d51b15e26fb5ed47171b`
+- SPEC-v5: `a6d07ade835758e8488ca10d3b0631caf0beb93ea3a6733631f151b0c2f01433`

+
+## Locked constraints
+
+- Build against the ratified design; do not re-derive it.
+- Product code only in `packages/mosaic`; Gate0 Python probes are reference prototypes and are not shipped.
+- Caller-supplied/asserted `session_id` is refused.
+- Tokens use the operating-system CSPRNG via Python `secrets`; never `Math.random` or model output.
+- Socket parent directory mode `0700`, socket mode `0600` minimum; document distinct-principal deployment as the stronger T-C-closing posture.
+- Red-first TDD for six named cases; new-code coverage >=85%.
+- No merge. PR must say `closes #828`; exact 40-character head handed to Mos for Opus-SECREV and independent review.
+
+## Plan
+
+1. Load security/testing/docs guidance and inspect existing `packages/mosaic` architecture.
+2. Write the six required tests first and capture RED evidence.
+3. Implement minimal broker modules and CLI/runtime integration necessary for product use.
+4. Run focused tests with coverage, package gates, then full repository gates/suite.
+5. Run author-side review/remediation, commit `closes #828`, queue guard, push, and open PR through Mosaic wrappers.
+6. Send PR number + exact head SHA to `web1:mosaic-100`; stop without merging.
+
+## Risks / boundaries
+
+- Same-UID counterfeit socket replacement remains the disclosed T-C residual unless broker runs under a distinct principal; filesystem modes alone are minimum hardening, not a complete authenticity proof.
+- `.mosaic/orchestrator/mission.json` and `.mosaic/orchestrator/session.lock` were already modified at session start and must not be included in this PR.
+- Repository Woodpecker pipelines exist; CI is the canonical build path. No manual image build/deploy is in scope.
+
+## Progress / evidence
+
+- 2026-07-18 session start: mandatory mission files and orchestration guides loaded.
+- STEP 0: all four authority hashes matched; artifacts read in full.
+- Branch/HEAD confirmed; issue #828 open; Gate0 evidence hash confirmed.
+- Initial RED: focused Vitest acceptance suite failed 11/11 because the product daemon did not exist; the expected missing-product failure was observed before implementation.
+- Review-remediation RED: partial/zero-progress state writes, nested corrupt state, symlink state, canonical starttime, and duplicate-anchor generation behavior failed before their fixes. Real socket RED/GREEN runs were executed by the unrestricted parent harness because the delegated worker sandbox denies `AF_UNIX.bind()`.
+- Product implementation added at `packages/mosaic/framework/tools/lease-broker/daemon.py`; Gate0 probe scripts were read as references but not copied or shipped.
+- Independent Codex code review round 1 found 2 blockers + 1 should-fix (connection stall/crash, partial writes, packet-dependent framing); all were remediated with tests.
+- Independent Codex code review round 2 found 2 blockers + 1 relevant should-fix (half-close contract ambiguity, incomplete persisted-state validation, symlink/non-regular state); all were remediated with tests and documentation. Pre-existing `.mosaic/*` session dirt remains excluded from the PR.
+- Unrestricted focused situational suite: `35/35` GREEN.
+- New Python product module coverage: `90%` (`356` statements, `36` missed), above the user-required 85%.
+- Root typecheck: `42/42` Turbo tasks GREEN.
+- Root lint: `23/23` Turbo tasks GREEN.
+- Root format check: GREEN.
+- Package build + suite: `71/71` files and `1,369/1,369` tests GREEN, including framework shell tests.
+- Full root suite: `43/43` Turbo tasks GREEN after the oversized-frame production race fix.
+- Focused acceptance suite: `35/35` GREEN in three consecutive unrestricted runs; exact-head instrumented run also `35/35` GREEN.
+- Exact-head Python product coverage: `90%` (`365` statements, `37` missed), above the required 85%.
+- Review-triggered oversized-frame race was fixed in production by bounded drain-to-EOF; tests were not changed.
+- Commits banked in red/green cadence: `d61c5441` (RED contract), `deb11df7` (GREEN implementation/docs), `57770e34` (oversized-frame production fix).
+- Final-review blocker remediated: added a 256-token pending-state cap, deletion on consume/generation revocation, pre-open serialized-size enforcement, and request-wide in-memory rollback for every broker mutation/commit failure while retaining the v1 live-token schema.
+- Distinct-principal docs now state built-in `0700`/`0600` is same-principal only; WI-1 does not provide the external identity-preserving proxy/ACL/service boundary needed for the stronger deployment.
+- Exact Python unit suite: `8/8` GREEN. Unrestricted focused acceptance: `35/35` GREEN.
+- Exact-head package build/suite: `71/71` files and `1,369/1,369` tests GREEN.
+- Exact-head Python product coverage: `90%` (`376` statements, `36` missed), above required 85%.
+- Root typecheck: `42/42` GREEN. Root lint: `23/23` GREEN. Root format check and `git diff --check`: GREEN.
+- Final exact-head rereview found two persistence blockers: post-rename directory-fsync uncertainty and acceptance of impossible persisted token records. RED was captured as three invariant failures plus one missing fail-stop error; commits `a94b1220` (RED) and `d05465e5` (GREEN) remediate both without weakening tests.
+- Post-remediation evidence: Python unit suite `10/10`, focused real-socket acceptance `35/35`, full root suite `43/43` Turbo tasks, broker coverage `90%` (`395` statements, `38` missed), lint `23/23`, typecheck `42/42`, format check and `git diff --check` GREEN.
+- Independent Codex review of remediation commit `d05465e54736c4966294c4af8fbd6a4ad8fe81aa`: APPROVE, confidence `0.94`, zero findings. Reviewer sandbox could not allocate temp directories; unrestricted parent test evidence above is canonical.
+
+- Remediation session: terra review comment `18072` reproduced a SERIAL-ACCEPT DoS; scope is RED regressions plus bounded concurrent connection handling on PR #836, preserving all existing broker security properties.
+- RED evidence against reviewed daemon: four silent peers delayed registration `3920 ms` beyond the `1500 ms` bound; 16 silent peers were not reaped within `2500 ms`. The first bounded implementation then exposed slot exhaustion by rejecting the valid queued caller with `EPIPE`; admission was corrected to wait for a reclaimed bounded slot. GREEN evidence: queued-peer test `211 ms`; strengthened cap/reap/reclaim test `1118 ms`; complete real-socket acceptance `37/37` and Python persistence suite `10/10`.

+
+1. Mandatory Opus-SECREV on the exact PR head; no GPT/terra substitute.
+2. Independent exact-head code review and exact-head RoR before Mos-authorized merge.
+3. Mos retains merge authority; this WI author stops after PR + full 40-character head handoff.

+# WI-2 Scratchpad — Whole mutator-class gate
+
+- **Issue:** Gitea #829
+- **Branch:** `feat/829-mutator-gate`
+- **Base HEAD:** `8ec67a1126adb0dcd4c3a2bf5525f3e239c0b201`
+- **Role:** sol author/build lane only; terra code review and Opus security review are coordinator-owned.
+
+## Mission prompt
+
+Implement BUILD-BRIEF Deliverable 2 as a framework-native whole mutator-class gate under `packages/mosaic/`, building against the merged WI-1 lease broker. No consequential mutator may succeed while UNVERIFIED after a compaction observer fires or after TTL. Carry the T-B compromised-tool acceptance criteria. Enforce revoke-first and promote-last structurally. A receipt is only a promotion prerequisite; the mutator-class gate remains the safety mechanism. M1 is Claude + Pi only.
+
+## Authority verification

+Verified exact SHA-256 before design/code:

+Carried authority chain also verified/read for the locked T-B gate contract: SPEC-v4 `a5e9c261…`, v4 sol `1e76ee59…`, SPEC-v3 `e0830ba0…`, v3 sol `9f321ade…`.
+
+## Plan
+
+1. RED real-socket acceptance tests for default-deny whole classes, T-B raw-tool bypass, observer/TTL revocation, and structural revoke-first/promote-last.
+2. Extend the merged WI-1 broker as the sole lease authority; authenticate every transition through existing peercred/ancestry/session logic and consume WI-1 single-use cycle tokens atomically before promotion.
+3. Add one broker-backed runtime gate executable and wire it across all Claude `PreToolUse` tools and Pi `tool_call`; unknown/custom tools deny by default.
+4. Add proportional protocol/security/operations documentation and requirements-to-evidence mapping.
+5. Run focused coverage, package/full suites, lint/typecheck/format, then queue-guard, push, open an unmerged PR with `closes #829`, and hand off the exact head.
+
+## Risks and bounds
+
+- Receipt parsing/builders and compaction observers are later WIs; WI-2 exposes the promotion prerequisite boundary but does not treat a receipt as safety authority.
+- Broker restart intentionally loses volatile VERIFIED leases and therefore restarts UNVERIFIED; persistent WI-1 identity/token state remains unchanged.
+- The gate is whole-class and does not parse shell command strings. T-C extension/hook absence and same-UID broker replacement remain outside the client guarantee and server branch protection remains the backstop.
+- Initial lease TTL is capped at ratified 300 seconds; callers may only shorten it.
+- Working budget assumption: 35K tokens; reduce documentation/refactor breadth before touching locked scope if pressure rises.
+
+## Progress and verification
+
+- RED #1: all 5 initial real-socket contract tests failed on WI-1 with `UNKNOWN_ACTION` or missing adapter behavior.
+- RED #2: register-before-exec runtime test failed because `launch-runtime.py` did not exist.
+- GREEN: broker-owned volatile lease state, 300-second maximum monotonic TTL, WI-1 token-backed promotion, all-tools runtime gate, Claude/Pi wiring, and register-before-exec launcher delivered without changing WI-1 peercred/ancestry authority.
+- Focused broker + gate acceptance: `43/43` GREEN.
+- Instrumented Python coverage: `88%` total — daemon `89%`, register/exec launcher `86%`, runtime gate `86%`.
+- Full repository suite: `43/43` Turbo tasks GREEN; `@mosaicstack/mosaic` `72/72` files and `1,377/1,377` tests GREEN.
+- Root typecheck: `42/42`; lint: `23/23`; format check and `git diff --check`: GREEN.
+- No author self-review was run. Exact-head terra CODE and Opus SECREV remain coordinator-owned gates.
+
+## Acceptance mapping
+
+| Acceptance criterion | Evidence |
+| --- | --- |
+| No consequential mutator succeeds while UNVERIFIED after observer revoke or TTL | `observer revocation and monotonic TTL expiry deny the next mutator` real-socket acceptance test |
+| T-B compromised-tool bypass is covered by the whole gate | `T-B raw and custom mutator tools are default-denied without shell parsing` across Claude/Pi built-ins, raw Bash class, MCP/custom/unknown tools |
+| Revoke-first / promote-last is structural | `revoke-first and promote-last structurally bracket mutator authority`; direct promotion rejected, pending remains denied, token consumption commits before VERIFIED |
+| Consume WI-1 auth/lease substrate | All transitions and decisions traverse merged peercred/ancestry authentication; promotion consumes the exact WI-1 CSPRNG cycle token |
+| M1 Claude + Pi | Claude `.*` PreToolUse and Pi `tool_call` invoke the same broker gate; register-before-exec test proves broker-minted parent identity reaches runtime descendants |
+
+## Locked discipline
+
+- Re-verify and read the four authority artifacts before design or code.
+- RED-first tests must cover unverified mutation refusal, T-B compromised-tool refusal, and revoke-first/promote-last ordering.
+- Consume WI-1 VERIFIED-lease state; do not re-derive kernel identity, ancestry, sessions, or token authentication.
+- Minimum 85% new-code coverage; full suite, lint, typecheck, and format checks green.
+- Build only: no self-review and no merge. Open a PR containing `closes #829`, report its exact 40-character head, then exit.
+
+## Remediation — terra CODE comment 18091
+
+- Coordinator correction: terra returned REQUEST CHANGES at head `77b137ccc04b5be035cac5ca21bbbf3df8b94f97`; Opus SECREV was GO and CI green, but no evidence transfers to the remediated head.
+- BLOCKER 1 verified: first-class Claude/Pi route through `execLeaseGatedRuntime`, while the supported Claudex path preserves isolation but directly invokes `claude`; it therefore registers no anchor, injects no lease session, and the isolated config has no guaranteed all-tools gate hook.
+- BLOCKER 2 accepted: prior 88% was aggregate evidence. Remediation must produce independently measured branch coverage of at least 85% for each new executable (`launch-runtime.py`, `mutator-gate.py`, and daemon delta evidence), including successful exec-boundary collection and validation/error branches.
+- Remediation discipline: RED tests first; preserve the reviewed-good broker lock/state-transition ordering; update PR #837 on the same branch; no self-review or merge.
+
+### Remediation evidence
+
+- RED commit `046896c6`: both `mosaic claudex` and `mosaic yolo claudex` behavioral probes exited 1 because the direct path supplied neither a broker session nor the isolated all-tools hook; branch-focused Python tests failed on the absent injectable boundaries. Fresh WI-2 daemon-delta instrumentation also failed the ≥85% branch gate at 75%.
+- GREEN: Claudex now exposes only `execLeaseGated`, passes the preserved isolated proxy environment through the shared register-before-exec wrapper, and merges the exact `.*` mutator hook into isolated `settings.json` with mode `0600`. Missing broker/identity, malformed or symlinked settings, and an unverified consequential tool all fail closed. The broker transition/lock implementation was not changed.
+- Behavioral regression: normal and YOLO Claudex both receive a 64-hex broker session, retain their mode-specific arguments, observe the exact all-tools hook, and receive status 2 for unverified `Bash`.
+- Independent branch coverage: `launch-runtime.py` 16/18 = **89%** (statements 98%); `mutator-gate.py` 21/22 = **95%** (statements 99%); `daemon.py` WI-2 delta 35/40 = **88%** (whole-file branch 80%, statements 90%).
+- Fresh focused real-socket coverage run: WI-1 + WI-2 acceptance `46/46`; persistence `10/10`; branch unit suite `10/10`.
+- Fresh full repository suite: `43/43` Turbo tasks; `@mosaicstack/mosaic` `72/72` files and `1,381/1,381` tests.
+- Fresh root gates: typecheck `42/42`; lint `23/23`; format and `git diff --check` GREEN.
+- PR #837 remains open and unmerged. Terra CODE and Opus SECREV must both rerun from zero on the exact remediated head before coordinator-owned merge authorization.
+
+## Remediation round 3 — terra CODE comment 18099 + binding upgrade
+
+- Locked-good surfaces: Claudex gating and B2 per-executable coverage are verified; do not regress them. Broker state-transition/lock ordering remains untouched.
+- Mechanical repository sweep found direct executing Claude entries in PRDY init, PRDY update, QA remediation, and `@mosaicstack/coord` task launch. It also found a direct Claude command rendered into the QA report template and documentation examples. Existing Mosaic CLI Claude/Pi/Claudex, orchestrator session-run, and fleet starts already reach the gated boundary.
+- Elevated hard requirements: ship a permanent suite/CI guard that scans production source and fails on any direct Claude/Pi launch; route every executing entry through one common gated wrapper; add real-broker RED/GREEN tests for PRDY init/update and QA; preserve each environment and denial behavior; independently measure all new executable coverage at ≥85%.
+- Round-3 plan: first commit RED behavioral and scanner-contract tests; then add one framework `launch-runtime.sh` choke-point over `launch-runtime.py`, make Mosaic CLI and shell launchers use it, make coord route through `mosaic`, and wire the permanent guard into package tests. Update all discovered operator-facing direct-launch examples so the scanner inventory remains complete.
+
+### Round-3 outcome
+
+- RED commit `7f3418fa`: PRDY init, PRDY update, and QA remediation all reached the fake Claude binary without a broker session even when the configured socket did not exist; the permanent-guard contract initially failed because its executable was absent, then failed against the five discovered direct entries (four executing plus the QA command template).
+- Choke-point decision: a new shell layer was unnecessary. Every executing repository entry now converges directly or through `mosaic`/`execLeaseGatedRuntime` on the existing single `launch-runtime.py` register-then-exec wrapper. PRDY and QA preserve their working directories, prompts, flags, logging pipe, and environment. Coord rewrites direct Claude commands to `mosaic claude` and rejects unknown custom Claude launchers fail-closed.
+- Permanent guard: `packages/mosaic/framework/tools/lease-broker/check-runtime-launches.py`, invoked by `packages/mosaic/package.json` `test:framework-shell` and therefore root `pnpm test`/CI. It scans production code under `packages/`, `apps/`, `plugins/`, and `tools/` and rejects literal, absolute-path, process-API, command-array, and dynamic Claude/Pi launch forms. Synthetic bypass tests are permanent at `runtime_launch_guard_unittest.py`.
+- Mechanical inventory: **14 gated / 14 total** — coord 2, fleet 1, QA 2, orchestrator 3, PRDY 2, Mosaic Claude/Pi/Claudex adapter/boundary 4. No verification-layer fallback or follow-up issue is needed because the single code-level wrapper was achieved.
+- Real-socket behavioral evidence: PRDY init, PRDY update, and QA remediation each fail before runtime execution when the broker is absent; with the broker present they receive a broker-minted 64-hex session and the unverified `Bash` authorization exits 2. Claudex normal/YOLO and the broker state machine remain GREEN.
+- Fresh branch coverage: `launch-runtime.py` **18/18 = 100%**; `mutator-gate.py` **22/22 = 100%**; permanent guard **36/38 = 95%**; `daemon.py` WI-2 delta **35/40 = 87.5%**. All attributable executable statement coverage is at least 98%.
+- Fresh focused suites: broker + mutator real-socket acceptance `49/49`; persistence `10/10`; launcher/gate branch suite `13/13`; permanent guard suite `7/7`; coord `19/19`.
+- Fresh full repository suite: `43/43` Turbo tasks; `@mosaicstack/mosaic` `72/72` files and `1,384/1,384` tests. Root typecheck `42/42`, lint `23/23`, format, and diff checks GREEN.
+- PR #837 remains open and unmerged. Terra CODE and Opus SECREV must both rerun from zero on the exact round-3 head before coordinator-owned merge authorization.
+
+## Remediation round 4 — terra CODE comment 18104
+
+- Locked-good surfaces: the 14/14 launch inventory, single `launch-runtime.py` choke-point, real-socket launcher behavior, coverage, Claudex gating, and broker state machine must not change.
+- Reproduced RIDER E exactly at head `1792b7934dda7eff64a207b8b0edb9c460d4164b`: a temporary production file containing `exec claude --dangerously-skip-permissions "terra-r3" # launch-runtime.py` made the guard exit 0 and report `1 gated/1 total`.
+- Root cause: classification searched the unparsed physical line, and the broad gated regex treated any `launch-runtime.py` substring—including comments and inert arguments—as an invocation before the direct-launch finding was evaluated.
+- Round-4 plan: add permanent RED cases for the exact comment evasion plus string-argument, echo, and unrelated-variable marker evasions; tokenize/strip comments by launcher syntax; recognize only command-position wrapper invocations with `--runtime` and the gated command separator; retain 14/14 real inventory; rerun guard coverage and all gates fresh.
+- Mos Rider A/B decision: adopt **both** defenses. Command-position parsing remains necessary because a normal `claude -p` launch is consequential even without the dangerous flag. The primitive-location invariant is more mechanically robust for dangerous mode because it does not need to recognize a wrapper marker at all. Move the sole raw `--dangerously-skip-permissions` literal into `launch-runtime.py`; any occurrence in another production file is independently RED.
+- Rider-A RED matrix adds heredoc body, backslash continuation, non-first `;`/`&&`/pipe commands, command substitution, `eval`, and variable-execution indirection in addition to the six marker/comment evasions. Before the augmented implementation, primitive ownership, command substitution, `eval`, variable execution, and the preserved 14-site inventory all fail.
+- Round-4 GREEN uses both defenses. Quote-aware comment stripping removes shell/Python `#` and JS/TS line/block comments; shell command prefixes are segmented with `shlex`; validated wrappers require `launch-runtime.py` in command position, `--runtime`, and the `--` command separator; multiline TypeScript wrapper calls are validated as complete invocations. Direct command syntax wins over markers, while tracked runtime assignments plus `eval`/variable execution, command substitution, chained commands, heredocs, continuations, and `env`/`command`/`nohup` prefixes are rejected.
+- Primitive ownership is independently load-bearing: `launch-runtime.py` is the sole production owner of the raw Claude dangerous flag. Mosaic, Claudex, and PRDY request semantic `--dangerous`; the wrapper validates Claude and injects the primitive immediately before register/exec. This preserves actual YOLO argv behavior while making any raw primitive elsewhere fail without relying on wrapper-name recognition.
+- Permanent guard suite now has 10 tests and 31 direct-launch forms, including 18 new round-4 marker/comment/indirection/prefix evasions plus harmless-marker and multiline-wrapper controls. Terra's exact add-ungated source is exercised through the CLI effectiveness test. Repository inventory remains exactly **14 gated / 14 total**.
+- Fresh round-4 coverage: guard **97%** branch-aware aggregate (241 statements, 110 branches); `launch-runtime.py` **100%**; `mutator-gate.py` **100%**. The daemon is byte-unchanged from the round-3 head whose WI-2 delta is **87.5%**.
+- Fresh round-4 gates: real-socket acceptance **49/49**; persistence **10/10**; launcher/gate **14/14**; guard **10/10**; coord **19/19**; Mosaic **1384/1384**; root **43/43**; typecheck **42/42**; lint **23/23**; format and diff checks green.
+
+## Remediation round 5 — terra 18116 + Opus 18114
+
+- Both independent gates converged on one guard-only completeness gap at round-4 head `1eb77c17f3147d4fa9944f77f1826243135b9cc0`; all round-4 primitive anchoring, command-position parsing, 14/14 inventory, broker ordering, and coverage remain locked-good.
+- Reproduced exactly: a temporary production source containing `launcher=claude` followed by `exec "$launcher" -p x` exits 0 with `0 gated / 0 total`. The literal command resolver skips prefixes but cannot resolve a tracked variable; the variable resolver handles only bare/eval references and cannot skip prefixes.
+- Round-5 plan: add 10 permanent RED forms (quoted/unquoted `exec`, `command`, `nohup`, and `env` with assignment, each multiline and same-line), then unify shell command-position resolution so literal and tracked-variable terminal tokens traverse the same prefix parser. Retain an independent variable-reference backstop, the 14/14 inventory, and every round-4 regression.
+- Mos stopping-criterion augment: command parsing is explicitly best-effort rather than a complete shell interpreter. Add B1 proving a parser-exotic alias launch with the raw dangerous flag is still RED by primitive anchoring, and B2 proving a parser-missed non-dangerous alias launch reaches the global `.*` hook and fails closed with `GATE_UNAVAILABLE` when no lease session exists. Document A (realistic parser matrix) + B (robust residual backstops); fresh reviewers supply criterion C (no new non-overlapping finding).
+- RED commit `91a4a983`: all 10 prefix×variable cases failed as expected before the fix—quoted/unquoted `exec`, `command`, `nohup`, and `env A=1`, each in multiline and same-line assignment shapes.
+- GREEN structural resolution: `shell_command_tokens()` now owns command-position prefix skipping for both literal and variable callers, including nested `exec`/`command`/`nohup`/`env` ordering. `runtime_variables` is threaded into `is_shell_direct_invocation()` and the same terminal-token resolver backs `executes_runtime_variable()`; exact `$v` and `${v}` references are resolved after `shlex` removes quoting.

+# WI-3 Scratchpad — Compaction revocation and runtime-generation rollover
+
+- **Issue:** Gitea #830
+- **Branch:** `feat/830-compaction-revoke`
+- **Base HEAD:** `abd2791f59b3f06f46dd08e55298ced72f6aa7c2`
+- **Role:** sol author/build lane only; terra CODE and Opus SECREV are coordinator-owned.
+
+## Mission prompt
+
+Implement BUILD-BRIEF Deliverable 3.3 and D4 on merged WI-1/WI-2 under `packages/mosaic/`. Claude `PreCompact` and `SessionStart(matcher=compact)` plus Pi `session_before_compact`/`context` equivalents must revoke the active lease through the existing broker state machine. Any `runtime_generation` bump—including same-PID reload/resume/fork—must auto-revoke the prior incarnation so the new generation inherits no prior lease. M1 is Claude + Pi only.
+
+Honor amended D2-v5 exactly: hard fail-closure when at least one observer fires or after lease expiry; both observers missing within TTL is an explicitly named bounded residual stale window (maximum 300 seconds, soak-tighten only), with no claim that the mutator gate bounds actions inside that window; total gate-hook miss is T-C. T12b/T30 must report both the within-TTL ALLOWED outcome and after-TTL DENIED outcome.
+
+## Session start verification
+
+- Worktree is clean on `feat/830-compaction-revoke` at exact required base `abd2791f59b3f06f46dd08e55298ced72f6aa7c2`; `origin/main` is the same SHA and includes merged WI-2 atop WI-1.
+- Authority SHA-256 verified:

+- P6 planner-return ruling SHA-256 `b7bbb6ea6e8d9a5c3366993642ab4e4f65b961af04936dcac20bfbcdcbaf1a09` read directly: feature WI admission is GO with the exact-delivery empirical compatibility fact and disclosed T-C middle-drop residual; no receipt redesign.
+
+## Plan and budget
+
+1. RED real-socket acceptance for T12b/T30, each Claude observer, same-PID generation rollover, Claude/Claudex hook wiring, and Pi lifecycle wiring.
+2. Add one broker client executable for observer revocation plus a private monotonic generation-file helper shared by launcher, gate, and revoker.
+3. Wire Claude `PreCompact`, `SessionStart(compact)`, and resume/clear generation rollover; merge equivalent mandatory hooks into isolated Claudex settings.
+4. Wire Pi pre/post compaction observers and reload/new/resume/fork generation rollover with local fail-closed tool blocking if lifecycle revocation fails.
+5. Document the D2-v5 bounded stale window without claiming the mutator gate bounds within-TTL actions; update protocol/security/operations/sitemap/checklist.
+6. Run focused real tests, independently measured executable coverage ≥85%, full repository gates, commit/push, open an unmerged `closes #830` PR, and hand off for terra CODE + mandatory Opus SECREV.
+
+Working estimate: **35K tokens**. No explicit hard cap was supplied; reduce refactor breadth before touching locked broker authority/state-machine semantics.
+
+## RED evidence
+
+- New T12b/T30 test already reports the inherited primitive honestly: within-TTL **ALLOWED**, after-TTL **DENIED**. The complete AC remains RED because the mandatory threat-contract document is absent.
+- Focused real-socket suite is RED with 7 expected failures: missing revoker executable (both Claude observers + generation bump), missing Claude/Pi wiring, missing isolated Claudex observers, and missing D2-v5 disclosure.
+- Branch-focused Python suite is RED on the wished generation initializer/resolver interfaces and missing `lease_generation.py` / `revoke-lease.py`.
+- Pi lifecycle suite is RED because the wished standalone `lease-lifecycle.ts` observer/generation module does not exist.
+
+## Locked discipline
+
+- RED-first T12b/T30 and observer/generation tests; test commit precedes implementation.
+- Reuse broker `revoke_lease`; do not fork identity, lease, or transition authority.
+- Preserve revoke-first/promote-last and WI-1/WI-2 reviewed state machine.
+- ≥85% attributable executable coverage with real tests.
+- No author self-review, no merge, no `--no-verify`.
+
+## Local implementation complete (push held)
+
+Implemented on the WI-3 base `abd2791f59b3f06f46dd08e55298ced72f6aa7c2` without changing the reviewed broker state machine:
+
+- Added `revoke-lease.py`, which authenticates through the existing broker session/generation and invokes `revoke_lease`. A fired observer that cannot confirm broker revocation advances the private generation as a local fence before returning non-zero.
+- Added `lease_generation.py`: owner/type/mode/size validation, no-follow opens, exclusive bump lock, monotonic `int64` generation, write-all + `fsync`, and fail-closed exhaustion/corruption handling.
+- `launch-runtime.py` creates `generation-<broker-session>.state` mode `0600` beside the socket before `exec`; `mutator-gate.py` resolves that current file value on every tool check.
+- Claude settings and isolated Claudex settings now preserve/install `PreCompact`, `SessionStart(compact)`, and resume/clear rollover hooks in addition to the global all-tools gate.
+- Pi now registers tested `session_before_compact`, `session_compact`→first `context`, and `session_start(reload|new|resume|fork)` handlers. Failed pre-compact revocation cancels compaction; failed post-compact/rollover revocation latches local all-tool denial.
+- Added PRD requirements, architecture/security/protocol/operations updates, sitemap entry, and the ignored-by-default documentation checklist (force-add required at commit).
+
+### Acceptance and coverage evidence
+
+- Focused acceptance: `19/19`; T12b/T30 prints within-TTL **ALLOWED** and after-TTL **DENIED**.
+- Pi lifecycle: `8/8`, with **100% statements/branches/functions/lines** attributable coverage.
+- New Python generation/revoker: `24/24`, **99% branch-aware aggregate coverage** (`lease_generation.py` 98%, `revoke-lease.py` 100%).
+- Mosaic package: `1399/1399`; framework shell Python `24/24`, launch guard `12/12`, permanent launch inventory `14 gated/14 total`.
+- Existing lease-broker real-socket acceptance: `37/37` within the package run.
+- Full repository: `43/43` Turbo tasks green; gateway `628 passed / 12 skipped`; Mosaic `1399/1399`.
+- Root typecheck: `42/42`; lint: `23/23`; format and `git diff --check` green.
+- Initial direct package test without first building the package reproduced the known missing-`dist/cli.js` harness condition; the canonical root Turbo test (which schedules `@mosaicstack/mosaic#build`) and explicit package build+test are green. No test was weakened.
+
+### Review evidence
+
+- Codex uncommitted code review: **APPROVE**, confidence `0.88`, zero findings. Its read-only sandbox could not rerun Vitest, but the author-side focused and full suites above were green.
+- Codex uncommitted security review: risk **none**, confidence `0.91`, zero findings.
+- Coordinator-mandated fresh exact-head terra CODE and Opus SECREV remain pending after rebase/push clearance; these local reviews do not replace that final gate.
+
+### Hold and residuals
+
+- **DO NOT PUSH OR OPEN A PR YET.** Coordinator requires flake-fix #838 to land, then WI-3 must rebase onto deterministic-green `main` before push.
+- Merge remains gated on #838, #827 Probe 3, and combined GO.
+- Named residual retained verbatim: when both observers are entirely missed, within-TTL consequential actions remain allowed; only lease expiry denies after the bounded stale window. No within-window mutator-action bound is claimed.
+
+## Deterministic-main rebase evidence
+
+- Fetched and confirmed `origin/main` at `8dfcf1903e385f977121069f798f476eb671fffc` (`#838` bounded broker deadlines, empty-read fail-closure, and de-flaked acceptance client).
+- Linear rebase completed. The only content conflict was `packages/mosaic/src/mutator-gate/runtime_tools_unittest.py`; resolution retained #838's `subprocess`/`threading` deadline regressions and WI-3's `stat` generation-state coverage. No authority/state-machine choice was ambiguous.
+- `packages/mosaic/src/mutator-gate/mutator-gate.acceptance.spec.ts` auto-merged on top of #838's shared `requestBrokerReply` helper. No inline socket/`JSON.parse` client was resurrected.
+- Verified WI-3 has zero diff from `origin/main` for #838-owned `daemon.py`, `broker-test-client.ts`, `lease-broker.acceptance.spec.ts`, `vitest.config.ts`, and `packages/mosaic/package.json`; bounded deadlines and the de-flaked harness are preserved byte-for-byte.
+- Required verbose acceptance command: **2 files / 56 tests green**. T12b/T30 still prints within-TTL **ALLOWED** and after-TTL **DENIED**.
+- Full Mosaic package after explicit build: **74 files / 1408 tests green**; deadline unit `2/2`, runtime tools `25/25`, launch guard `12/12`, inventory `14/14`.
+- Full repository: **43/43 Turbo tasks green**. Root typecheck `42/42`, lint `23/23`, format and diff checks green.
+- Attributable coverage remains Python **99%** branch-aware and Pi lifecycle **100%** statements/branches/functions/lines.
+- Push and PR remain held pending combined GO and all WI-3 merge gates. The coordinator-owned promote-lease-lost-ACK SPEC amendment/backstop is acknowledged as a future merge prerequisite and was not retro-expanded into this core rebase/build.

+- **Objective:** Deliver WI-5 receipt-challenge protocol ACs T25, T26, T28, and T29 only.
+- **Authority:** BUILD-BRIEF, SPEC-v5, ratification, and red-team hashes verified in STEP-0.
+- **Base:** `e522b22fa4492861b0fcd4a956a8795c54eb9bfe` (`origin/main`).
+- **Constraints:** Byte-build only: no live broker/socket/systemd/tmux mutation. No PR, self-review, or probe fire. T27/T30 are out of scope.
+- **Plan:**
+  1. Add red-first deterministic T26/T29 in-build tests that call shipped normative construction and broker path.
+  2. Add an unexecuted, isolated P5 out-of-process replay harness that drives the shipped daemon and asserts consume-before-promote for T25/T28.
+  3. Implement the broker-minted receipt challenge and exact receipt observation/consume/promote path.
+  4. Run unit, framework-shell, compile, lint, and type checks; push after the required queue guard; report to `mosaic-100`.
+- **Risks:** The standalone harness must drive the real daemon without a divergent fixture. If that is impossible, stop and flag Mos.
+- **Evidence:** Initial RED recorded in `/home/hermes/agent-work/reviews/832-wi5-red-receipt-challenge.log`; initial green checks passed. Remediation RED recorded in `/home/hermes/agent-work/reviews/832-wi5-remediation-red.log` before observer/payload implementation; remediation green passed. Remediation-2 RED recorded in `/home/hermes/agent-work/reviews/832-wi5-remediation2-red.log`: each rejected begin restored prior VERIFIED authority. Remediation-2 GREEN: receipt unittest (5: all `INVALID_CONSTRUCTION`, `PAYLOAD_CONSTRUCTION_REFUSED`, and `PAYLOAD_BINDING_MISMATCH` cases preserve UNVERIFIED and deny the next mutator), normative-fragments unittest (5), state-store regression (10), full mutator-gate acceptance (20, including the real begin → observer → consume → promote path), `py_compile`, Mosaic package lint/typecheck, and targeted Prettier check. The P5 harness remains unfired. Coverage tooling remains unavailable (`python3 -m coverage`: module not installed). Push pending.

+
+- **Objective:** Deliver WI-6 plus Mos-ruled B1/B2 and R2 Claude-only literal-argv repair: no shell-active recovery mapping bypass, unchanged Pi gate/B2 observer, AC-1/C4 preservation, and an unfired P6 probe.
+- **Authority:** STEP-0 SHA-256 verified 4/4 against the supplied BUILD-BRIEF, SPEC-v5, ratification, and red-team records.
+- **Base:** exact `07553ead337a70a9241f826d27571650262b289c`; new branch `feat/833-constrained-recovery-command`; merge-base assertion passed before any commit.
+- **Constraints:** No rebase/pull during build; no live install/symlink or live broker/socket/tmux/systemd/model-stream activation; no self-review, PR, merge, push, or P6 fire. `docs/TASKS.md` is orchestrator-owned and will not be modified.
+- **Plan:**
+  1. Add red-first unit tests against the recovery broker entrypoint for fresh recovery challenge, normal-receipt replay refusal, observable partial-delivery refusal, and the explicit middle-drop negative capability; commit the RED test and preserve its command output.
+  2. Implement the recovery command as a thin driver over shared WI-5 broker transitions and the trusted observer seam; it never accepts caller receipt text.
+  3. Add the source-resident skill under `packages/mosaic/framework/skills/`, plus a tmp-only #824 bridge projection test.
+  4. Build an unfired, default-3-run P6 standalone real-socket driver; it is not added to package scripts and will not be run.
+  5. Run targeted broker/mutator/receipt suites, lint, and format check; report head to `mosaic-100` and stop.
+- **Risks:** The observer can only represent an exact latest message. Tail-preserving middle-drop is intentionally not claimed receipt-detectable (T-C residual deferred to WI-7 server evidence).
+- **Evidence:** Original RED test committed at `3b5513bd6efad0c06b599fc759a66cff4286db04`; expected `UNKNOWN_ACTION` is logged in `/home/hermes/agent-work/reviews/833-wi6-red.log`.

P6 remains rebuilt and unfired. The ordinary package Vitest/lint/typecheck/root-format commands cannot resolve their executables in this intentionally dependency-free fresh worktree (`node_modules` absent); no install/symlink workaround was used.

+# Issue #838 — Broker acceptance socket flake
+
+## Objective
+
+Eliminate high-contention uncaught JSON parse failures in lease-broker and mutator-gate acceptance helpers without laundering malformed/empty replies into passing assertions.
+
+## Constraints
+
+- Branch: `fix/838-broker-acceptance-flake` in `/home/hermes/agent-work/stack-838-flakefix`.
+- Red-first TDD with a forced empty/truncated reply path and deterministic rejection or documented retry.
+- Read newline-framed replies completely; reject malformed broker replies with byte length/content context.
+- Determine RIDER2 branch before finalizing: test-harness-only `(a)` or daemon write truncation `(b)`.
+- If product-side, prove the real Claude/Pi adapter read path fails closed; fix any allow-risk.
+- Coverage >=85% per changed executable through real tests.
+- Full suite and repository gates green; independent exact-head review required.
+- Push and open a PR containing `closes #838`; do not merge.
+
+## Progress
+
+- 2026-07-17: Reclaimed from #824. Confirmed clean worktree on `fix/838-broker-acceptance-flake` at main base `abd2791f59b3f06f46dd08e55298ced72f6aa7c2`.
+- RED evidence: after dependency setup, `broker-test-client.spec.ts` failed to load the intentionally absent shared client module. Its contract forces empty-close retry, repeated truncated-close rejection with byte context, and newline-terminated malformed-reply rejection.
+- RIDER2 verdict: branch **(b)**. `daemon.py` starts one connection deadline before request reading, then may spend that budget waiting for `broker_lock`; after handling, `remaining <= 0` returns without writing. A timed `sendall` failure can likewise close after a partial write. A deterministic socketpair probe held the lock past `CONNECTION_DEADLINE_SECONDS` and observed `deadline_probe_reply_length=0`.
+- Adapter tripwire: real subprocess executions of `mutator-gate.py` for both `--runtime claude` and `--runtime pi` against actual Unix servers returning empty and truncated replies all exited 2 with `GATE_UNAVAILABLE`. Adapter fail-close is proven; there is no ALLOW risk.
+- Residual: production broker reply loss remains an availability-denial path under extreme contention, but cannot grant mutator authority. The acceptance-only client retries early closes and otherwise rejects with response byte length, escaped bytes, and hex; malformed newline-framed replies are never retried or converted to reply objects.
+- Shared client now owns newline framing and parsing for both acceptance suites. Focused suites pass 60 tests, including the real adapter tripwire.
+- Coverage gate: changed helper is 100% statements/lines/functions and 90% branches; existing `skill.ts` remains above 85% per-file thresholds.
+
+## Scope corrections and bounded product repair
+
+- Coordinator correction superseded the initial push/PR and retry language: this lane is BUILD-ONLY, and early-close retries are forbidden because they can mask a committed broker transaction. Nothing may be pushed or opened until explicitly cleared.
+- Revised RED evidence: the no-retry empty/truncated tests failed because the first failed exchange was retried into `{ ok: true }`; the daemon regression failed because a slow completed `broker.handle()` produced `b''` instead of a newline-framed reply.
+- Client repair: both former duplicated helpers use one shared reader. Empty, truncated, malformed, oversized, timed-out, and socket-error replies reject `BrokerTransportError` with a typed `kind`, attempt count fixed at one, response length, escaped bytes, and hex. No retry and no catch-to-reply conversion exists.
+- Product repair: `daemon.py` now has independent bounded read, broker-lock queue, and send budgets. Lock queue exhaustion returns explicit `BROKER_BUSY` before `broker.handle()` can mutate state. Once handling starts it finishes atomically, and its reply always receives a fresh send timeout instead of being skipped because read/lock/fsync consumed a shared deadline.
+- Product GREEN evidence: deterministic socketpair tests prove lock saturation returns framed `BROKER_BUSY` without invoking `handle()`, and a handle that completes after the former one-second shared deadline still returns its complete framed reply.
+- RIDER2b remains **fail-closed**: real Claude and Pi `mutator-gate.py` subprocesses against empty and truncated Unix-socket replies exit 2 with `GATE_UNAVAILABLE`; no malformed/default ALLOW was observed.
+- Residual/tripwire: an unavoidable peer disconnect or send failure can still lose acknowledgement after a valid transaction commits. The affected adapter call fails closed. A valid `promote_lease` may nevertheless remain VERIFIED after its acknowledgement is lost; that is authority-observability divergence requiring WI-3/Opus security review rather than expansion of #838. #838 does not add retries or attempt a protocol redesign.
+- Final package evidence: recursive Mosaic dependency build passed; 73 Vitest files / 1,392 tests passed; deadline unit tests 2/2, real runtime tool tests 15/15, launch guard tests 12/12, inventory 14/14, and shell regressions passed.
+- Final coverage: `broker-test-client.ts` 99.24% statements/lines, 86.11% branches, 100% functions under per-file >=85% thresholds. Repository typecheck 42/42, lint 23/23, and format check passed.
+- Independent Codex exact-head review requested one framing fix: a valid frame followed by trailing bytes in a later socket chunk could resolve before the garbage arrived. Security review also flagged complete token-bearing reply bodies in diagnostic properties/logs.
+- Review RED evidence: delayed cross-chunk garbage resolved `{ ok: true }` instead of rejecting, and a truncated `promotion_token` remained in the typed error. The tests use separate timed writes to prevent kernel/event-loop coalescing.
+- Review remediation: the shared client now accumulates through EOF, requires exactly one terminal newline, then parses inside a rejecting error boundary. Diagnostic bodies are capped at 256 bytes, sensitive broker fields are fully redacted, and a SHA-256 digest preserves correlation without credential disclosure.
+- Post-review coverage: `broker-test-client.ts` 99.35% statements/lines, 86.66% branches, 100% functions. Final full suite is 73 files / 1,394 tests plus all Python/shell gates; recursive build, typecheck, lint, and format are green.
+- Fresh exact-head Codex security review: risk `none`, no findings. Fresh code review found only that the real-adapter subprocess proof lacked a timeout; it now has a five-second bound and fails with runtime/wire context while closing the fake server. The focused Python suite remains 15/15 green.
+- Mandatory Opus SECREV remains coordinator-owned and pending before any push/PR decision; this build is intentionally local-only.

+
+- Task: `FCM-M5-001`
+- Issue: `#758`
+- Branch: `docs/758-fleet-config-operator-docs`
+- Exact base: `9745bc3f29c26b021a478b7ad03cfb494f6c9de3` (tree `4da210da9a71b035130d4160a4a2e691bdfde2da`)
+
+## Objective
+
+Deliver the accepted fleet documentation information architecture, operator workflows, operations and migration references, comprehensive contract documentation, and deterministic link/example validation without live fleet action or product mutation.
+
+## Scope and constraints
+
+- Documentation, examples, documentation validation, and tracking only.
+- `roster.yaml` remains the sole writable desired-state authority; generated state is derived/observed.
+- No M4-002 implementation or execution; no canary, migration, rollback, deployment, systemd/tmux/session, generated projection, or product mutation.
+- `mos-comms` is temporary and is not permanent architecture.
+- Parent issue `#758` remains open through M5.
+- No credentials, sensitive values, or privileged command content.
+
+## Plan
+
+1. Update tracking first with exact M4-001 evidence and mark M5-001 in progress.
+2. Map the M0 checklist and current implementation behavior to documentation pages.
+3. Author operator, operations, migration, schema/reference, recovery, troubleshooting, and security/authority docs.
+4. Add or extend deterministic documentation/link/example validation if required, red-first.
+5. Run repository documentation, link, example, and relevant package checks; review and remediate.
+6. Commit, queue-guard, push one branch, and open one wrapper-created PR; stop for independent review.
+
+## Budget
+
+- Task estimate: `24K`.
+- Working cap: stay within the card estimate by parallelizing read-only discovery and limiting edits to checklist-required artifacts.
+
+## Progress checkpoints
+
+- [x] Loaded repository/global delivery and documentation contracts.
+- [x] Verified `origin/main` is exact required base and created isolated worktree.
+- [x] Tracking updated first.
+- [x] Checklist mapped and docs authored.
+- [x] Validation green.
+- [x] Review/remediation complete.
+- [x] Commit, queue guard, push, PR #789.
+- [x] Rejected exact-head RoR findings repaired on a new descendant commit candidate.
+- [ ] New exact-head review and CI after repair push.
+
+## Tests and verification

+- Red-first documentation validator initially failed for the absent fleet entry point and canonical
+  example, then passed after the IA and example were added.

+- `pnpm format:check` — passed.
+- `pnpm lint` — 23 tasks passed.
+- `pnpm typecheck` — 42 tasks passed.

+- `bash packages/mosaic/framework/tools/quality/scripts/check-resident-budget.sh` — passed.
+- `git diff --check` — passed before final review.
+- Independent staged-snapshot review identified four documentation/validation blockers: reboot safety,
+  heartbeat observation, migration failure envelope, and example-scan coverage. All were remediated;
+  focused rereview approved the staged remediations with no blockers. Exact committed-head review remains
+  a post-PR gate.
+- Post-remediation `@mosaicstack/mosaic` lint/typecheck passed; package test passed 61 files / 1,045
+  tests; sanitization and resident-budget gates passed again.
+
+- Post-PR exact-head RoR on rejected head `0aee2c09819fd06e28f927384ea56fa2ef374edf`
+  identified five blockers: update-lifecycle overclaim, missing explicit `fleet validate` gap,
+  fragment-blind link validation, unsupported checklist-evidence claim, and insufficient example safety
+  validation. Red-first regressions failed before implementation for missing-heading, privileged-command,
+  and credential-format fixtures. Repairs now preserve/document implementation truth, validate heading
+  fragments, narrow checklist claims, and scan fenced/canonical examples for common credential formats
+  and privileged commands without printing fixture values.
+- Repair-focused fleet contracts: 7 files, 192 tests passed after review remediation; documentation
+  validator contributed 11 tests. Full gates passed: format; lint 23/23; typecheck 42/42; test 43/43
+  tasks with `@mosaicstack/mosaic` 61 files / 1,052 tests; sanitization; resident budget; and
+  `git diff --check`. New exact-head review/CI remain pending until the repair commit is pushed.
+
+## Risks/blockers
+
+- Checklist may include behavior intentionally deferred to M4-002/M5-002; such items must be recorded as approved-existing holds rather than claimed delivered.
+- Commands/examples must remain non-live and avoid privileged/sensitive content.
+
+## Final evidence
+
+- Pending.
