+ * This check fails LOUD at boot instead: if the pipe cannot see the DTO's

+ * It catches the whole class — erasure, decorator metadata loss — on every
+ * host, at the moment the damage exists rather than at first use.

+# Mosaic Stack Roadmap
+
+Companion to [docs/PRD.md](./PRD.md). Governed by the D11 rule: **every planned
+phase appears here from day one, even as a placeholder** — nothing exists only
+in heads. A phase marked _placeholder_ is a commitment to design it, not a
+design; scoping one requires its own PRD section or requirements doc plus
+review.
+
+Phases are product phases. The in-flight platform workstreams (KBN-100/101
+kanban SOT implementation, FCM #758, FCOM #766, TESS, RI #1275, and the other
+Part II contracts in the PRD) run as parallel tracks under their own issues
+and are prerequisites where noted.

+
+What exists on `next` today: web dashboard (login/register/SSO, chat,
+read-only projects/tasks, settings, admin user/system-health tabs), the
+Gateway, the CLI-first framework tooling, and the fleet control plane. The
+webUI audit (USC estate, webui-audit lane) measures the gap between this and
+P1.
+
+## P1 — v1 slice (D11)
+
+1. Standalone onboarding wizard: system/company name, component choices,
+   initial user, initial estate + project, seeded examples, re-runnable.
+2. Hierarchy core: company → estate → project → workspace → kanban, read-only
+   task bubble-up (kanban SOT Amendment A1 is the schema contract).
+3. Basic RBAC on the hierarchy.
+4. Minimal agent enrollment: one harness, API key, name/persona.
+
+Prerequisites: KBN-100/101 schema foundation; the D8 tool inventory and
+webUI→tool mapping (any missing tool is built first, D12).
+
+## P2 — connectors + comms + wizard expansion (placeholder)
+
+Email and drive connectors (Gmail/IMAP, Google Drive/OneDrive/Dropbox) with
+granular agentic-access consent; comms integrations (Matrix/Discord/Slack)
+including agent auto-enroll. Wizard gains the corresponding tabs (D4), plus
+the D4 capabilities deferred out of P1's minimal slice: expanded agent
+enrollment (OAuth login, multi-account, model choice with recommendation,
+account assignment, comms auto-enroll) and the Standalone SSO/OIDC
+configuration tab.
+
+## P3 — full onboarding profile + M365 (placeholder)
+
+Complete user onboarding profile (communication-style capture, optional
+voice-matching interview) under the D14 custody rule; M365 connectors,
+available to both deployment modes as ordinary connectors (same consent model
+as the P2 connector class). The Enterprise install flow's M365 prominence
+(D4) arrives with the Enterprise phase, P4.
+
+## P4 — Enterprise mode + conversion (placeholder)
+
+Enterprise install flow (org chart, RBAC focus, immediate OIDC, SSO
+prominent); per-user brains with architectural isolation (D14); Vault
+required; the one-way Standalone → Enterprise conversion (D3).
+
+## P5 — federation (placeholder)
+
+Connecting deployments: system-level config, assigned users, rights and
+data-access control, trusts with boundaries, strict data access, exfiltration
+monitoring. Explicitly not designed yet (D3); nothing in earlier phases may
+foreclose it. Requires its own PRD + threat model before any scoping.

+# Deployment Mode and Conversion Contract (D3)
+
+Status: DRAFT — awaiting ratification (webui-audit S2, contract 6 of 9).
+Authority: PRD D3 (Part I §3) — two modes chosen at install time,
+Standalone and Enterprise, with the mode table (brains, user-data
+isolation, secrets, conversion); Standalone → Enterprise conversion is
+**one-way** and Enterprise is a **terminal state**. PRD D14 (Part I §7)
+— the per-user brain split is optional in Standalone and keeping it is
+the recommended default because it preserves forward-compatibility with
+the one-way conversion. PRD D11 (Part I §9) — v1 ships the Standalone
+flow only; Enterprise conversion is explicitly deferred. PRD D3
+federation clause — federation is intentionally not fully designed,
+deferred, and nothing in v1 may foreclose it.
+
+Revision 2 (luna review F1–F7): the identity precondition restated in
+identity-contract terms with a conversion-local acknowledgment record
+this contract owns (F1); a durable, keyed preparation state with a
+Standalone-safe representation rule, an in-transaction re-check fence,
+and an exact flip boundary (F2); the §5.4 unknown-value rule stated
+directly without the contradictory non-exhaustiveness clause (F3); the
+D14 boundary bound here with a stable column-allowlist witness instead
+of delegated to an unratified layout (F4); the conversion witness
+matrix extended to every §4.2/§4.4 condition (F5); the mode-record
+writer coverage imported concretely from contract 1 §6.3 with a named
+schema, closed writer set, crafted-write probe, and mode-resolution
+assertion (F6); the mode read command flagged as a §12.1 drafting
+addition rather than a D8 mandate (F7). Ownership language aligned
+with contract 3 revision 2: mode is recorded at bootstrap and read by
+the wizard as input.
+
+This contract binds the mode as a canonical platform property (§2), the
+per-mode obligations and which contract owns each (§3), the conversion
+transition (§4), the v1 non-foreclosure obligations (§5), and their
+witnesses (§6). Domain semantics stay with their owning contracts:
+wizard branching (contract 3 §2), identity/SSO
+(`identity-lifecycle.md`), custody and per-user brain mechanics
+(contract 7, `custody-schema.md`), tool mapping
+(`tool-gateway-mapping.md`).
+
+## 1. Definitions
+
+1. **Mode**: the platform-wide deployment mode, exactly one of
+   `standalone` or `enterprise`. The vocabulary is closed in v1;
+   extension (e.g. a federation mode) is by amendment to this contract,
+   never ad hoc.
+2. **Conversion**: the one-way transition `standalone → enterprise`.
+   No other mode transition exists.
+3. **Conversion preconditions**: the verifiable conditions of §4.2 that
+   must all hold before the mode record may change.
+4. **Preparation unit**: one re-runnable piece of pre-conversion work —
+   the migration of one secret to the Vault backend, or the partition
+   of one user's brain content (§4.3).
+
+## 2. Mode is a canonical recorded property
+
+1. Mode is recorded canonically in the platform database at bootstrap
+   as the operator's install-time choice (D3: modes are "chosen at
+   install time"). The record is a single-row keyed record
+   (`platform_mode`: mode value, recorded-at timestamp, bootstrap epoch
+   reference); this contract owns it, the bootstrap writer performs the
+   one v1 write (§6.2), and the wizard reads it as input (contract 3
+   §2.3). Mode is never derived from feature state (presence of Vault,
+   count of brains, count of users), and no component may infer a
+   different mode than the record states.
+2. The record is readable by any authenticated user through a Gateway
+   command with CLI exposure. This read command is a **drafting
+   addition** ratified with this contract (PRD §12.1), not a D8
+   mandate: D8 binds only that any surface exposing the value goes
+   through official tooling. When a webUI surface consumes the read, a
+   mapping row is added to `tool-gateway-mapping.md` by amendment —
+   the same route §4.4 already binds for the conversion command.
+   Components branch on the read value only.
+3. The record is immutable except by the §4 conversion transition.
+   Editing it by direct database access, config file, environment
+   variable, or wizard re-run is non-conformant (contract 3 §2.3:
+   changing mode later is conversion, not a wizard re-run).
+
+## 3. Per-mode obligations (owner map)
+
+The PRD mode table binds four rows; this contract assigns each an
+owning contract so no obligation is unowned and none is bound twice:
+
+| Obligation          | Standalone                             | Enterprise                                         | Owner                                         |
+| ------------------- | -------------------------------------- | -------------------------------------------------- | --------------------------------------------- |
+| Brains              | one mosaic-brain (system + user files) | system brain for config + one brain per user       | contract 7 (custody/brain mechanics)          |
+| User-data isolation | single user                            | no user-data leakage between users; sharing opt-in | contract 7 (enforced by architecture, D14)    |
+| Secrets             | OpenBao/Vault or flat files            | OpenBao/Vault REQUIRED                             | this contract (§4.2 gate; steady-state check) |
+| Conversion          | may convert to Enterprise, one-way     | terminal state                                     | this contract (§4)                            |
+
+The Standalone brains row states the default layout, not the only
+valid one: the D14 per-user split is a MAY in Standalone with keeping
+it the recommended default (PRD §7, contract 7 §6), and Vault-backed
+secrets are equally valid Standalone configuration. Both prepared
+states are therefore themselves valid Standalone states — the fact
+§4.3 relies on.
+
+In Enterprise steady state, a flat-file secrets backend is
+non-conformant; the platform refuses to start Enterprise-mode
+components against a flat-file secrets configuration (fail-closed, not
+warn-and-run).
+
+## 4. Conversion transition
+
+1. **Direction and terminality.** The only transition is
+   `standalone → enterprise`. `enterprise → standalone` does not exist:
+   there is no command, no admin override, and no support path. An
+   attempt is refused with the precondition/state error class of the
+   command envelope (`tool-gateway-mapping.md` §4.2).
+2. **Preconditions (all verified before the record changes):**
+   - Secrets: OpenBao/Vault is configured and reachable, and every
+     required secret is served from the Vault backend — none from a
+     flat-file backend. Secret migration completes before conversion;
+     this contract does not define the migration tooling, only the
+     gate.
+   - Brains: the per-user brain split required by the Enterprise row of
+     §3 is established for **every** existing user (or the deployment
+     already kept the split, the D14 recommended default). Brain
+     partitioning mechanics are contract 7; this contract binds only
+     that the split is complete before the mode flips.
+   - Identity: at least one platform administrator account exists that
+     is active in identity-contract terms — authenticated capability,
+     not banned, not deactivated (identity §2, §5). And the conversion
+     request carries a **configuration acknowledgment**: the current
+     canonical values of registration mode and per-provider JIT
+     enablement (identity §2.2, §4.1), echoed back in the request. A
+     mismatch between the echoed values and the canonical values at
+     verification refuses the conversion. This acknowledgment record
+     is conversion-local, owned by this contract, and stored with the
+     §4.4 audit event as the precondition evidence; it adds no
+     identity-contract obligation and no mode-specific identity
+     default — identity's own defaults remain valid states.
+3. **Preparation state and the flip boundary.** Preparatory work is
+   tracked durably: each preparation unit (§1.4) records its
+   completion in a preparation table keyed by (bootstrap epoch, unit
+   identity — the secret's path, the user's id), written in the same
+   transaction as the unit's own effect where the unit's backend
+   allows it, and reconciled from the backend's actual state where it
+   does not (a secret already served by Vault, a brain already split,
+   is complete regardless of the table). Units are at-most-once per
+   key and re-runnable across attempts. **Standalone-safe
+   representation:** every preparation unit moves the deployment into
+   a state that is itself valid Standalone configuration (§3 note), so
+   an interrupted preparation leaves a fully operational Standalone
+   deployment reading its state through the ordinary contracts — no
+   rollback, fencing, or special Standalone read path is needed, and
+   no component behavior may key on "preparation in progress".
+   **The flip:** one transaction that (a) locks the mode record, (b)
+   re-verifies every §4.2 precondition after acquiring the lock, and
+   (c) writes the mode record and the §4.4 audit event. Any re-check
+   failure aborts with no write. External state that changes after the
+   re-check but before commit is bounded by the transaction window;
+   an external backend (Vault) failing after conversion is an
+   Enterprise runtime fault handled by §3's fail-closed steady-state
+   rule, not a conversion defect. An interrupted or failed conversion
+   leaves the record `standalone` and the platform fully operational;
+   there is no intermediate mode and no half-converted state
+   observable through the record.
+4. **Authority and audit.** Conversion is a platform-administrator
+   command carrying an explicit irreversibility acknowledgment in its
+   request (distinct from the §4.2 configuration acknowledgment). It
+   is an official Gateway/CLI command (D8): when built, it is added to
+   the tool↔Gateway mapping by amendment (`tool-gateway-mapping.md`
+   §3.3). The transition emits an audit event (actor, prior mode, new
+   mode, precondition evidence reference including the configuration
+   acknowledgment) in the same transaction as the record change; the
+   event survives indefinitely. A refused attempt emits a refusal
+   event naming the failed precondition class and actor, with no
+   mode-change event.
+
+## 5. v1 obligations (non-foreclosure)
+
+v1 ships Standalone only (D11); the conversion command is deferred
+work. v1 still MUST:
+
+1. Record the mode per §2 at bootstrap, with `enterprise` a reserved,
+   refused value for bootstrap — v1 bootstrap accepts `standalone`
+   only. The wizard reads the record (contract 3 §2.3); nothing in v1
+   writes it after bootstrap.
+2. Keep the §2.3 immutability rule: no v1 surface mutates the mode
+   record.
+3. Not foreclose conversion: the v1 platform database holds no
+   sensitive user content — sensitive categories live in the owning
+   user's brain, and postgres holds structure, consent records, and
+   pointers only (the D14 boundary, PRD §7). Custody mechanics are
+   contract 7's; this contract binds the boundary itself here so v1
+   cannot ship a layout that makes the §4.2 brain precondition
+   unsatisfiable, and §6.3 gives it a stable witness that does not
+   depend on contract 7's internals. Conversion implementation
+   additionally requires contract 7 ratified.
+4. Not foreclose federation: v1 components accept exactly the two §1.1
+   values wherever a mode value is parsed and refuse any other value
+   **before side effects** — a refused configuration, not undefined
+   behavior and not a crash mid-operation. Forward compatibility lives
+   in storage and architecture, not in parser speculation: the mode
+   record's storage is not structurally locked to two values (no
+   database-level two-value enum), and any future value (e.g. a
+   federation mode) is defined by a versioned amendment to this
+   contract before any component accepts it. The PRD defers
+   federation's shape entirely; this contract does not presume it
+   arrives as a third mode value.
+
+## 6. Verification requirements
+
+Binding on the implementing PRs:
+
+1. **Mode-record witness (v1):** after bootstrap the mode is readable
+   via the Gateway command and CLI and equals the bootstrap-recorded
+   choice; bootstrap with mode `enterprise` is refused; bootstrap with
+   any unknown mode value is refused before side effects (§5.4).
+2. **Writer-coverage witness (v1):** the mode record's writer set is
+   closed by the same three-prong static assertion contract 1 §6.3(b)
+   defines — symbol, class-table literal, and raw-execution prongs
+   with its allowlist composition rules — scoped to the
+   `platform_mode` table, with a writer allowlist containing exactly
+   the bootstrap writer in v1 (and exactly plus the conversion command
+   at the conversion milestone). Companions: a crafted direct write
+   attempted in a test fails and leaves the record unchanged; a
+   mode-resolution assertion that no shipped component derives mode
+   from feature state (mode reads occur only through the §2.2 read
+   surface — static assertion over Gateway, CLI, bootstrap, and
+   repository sources).
+3. **D14-boundary witness (v1):** a column-allowlist assertion in the
+   style of contract 1 §6.2 that the platform database schema contains
+   no sensitive-content column — the §5.3 boundary — stable regardless
+   of contract 7's internals (contract 7 §7 carries the full custody
+   witnesses).
+4. **No-downgrade witness (conversion milestone):** with mode
+   `enterprise`, a conversion request to `standalone` (and any crafted
+   mode-write) is refused with the precondition/state error class and
+   no record change.
+5. **Precondition witnesses (conversion milestone),** each refused
+   with no record change and no partial mode effect, parameterized
+   over both OpenBao and Vault where secrets are involved:
+   (a) secrets backend unreachable; (b) one required secret still
+   flat-file backed (migration incomplete); (c) one unpartitioned user
+   brain in a **multi-user** deployment where every other user is
+   partitioned; (d) no active platform administrator (the only admin
+   banned or deactivated); (e) configuration acknowledgment missing or
+   mismatching the canonical registration/JIT values; (f) actor not a
+   platform administrator (authorization refusal); (g) irreversibility
+   acknowledgment absent. And the steady-state rule: an
+   Enterprise-mode component started against a flat-file secrets
+   configuration refuses to start (§3).
+6. **Interruption and fence witnesses (conversion milestone):** fault
+   injection aborting conversion after each preparation unit and
+   between preparation and flip leaves the record `standalone` and the
+   platform operational in Standalone semantics (§4.3
+   Standalone-safety), and a re-attempt completes without duplicating
+   prepared state (at-most-once keys); a precondition invalidated
+   after preparation but before the flip (a secret reverted to
+   flat-file) is caught by the in-transaction re-check and refused.
+7. **Audit witnesses (conversion milestone):** a completed conversion
+   has exactly one mode-change audit event, same-transaction with the
+   record change (transaction linkage asserted), carrying actor, prior
+   mode, new mode, and the precondition evidence reference including
+   the configuration acknowledgment; a failed attempt has a refusal
+   event naming the failed precondition class and no mode-change
+   event; the mode-change event remains queryable after subsequent
+   unrelated audit activity (retention probe).
+8. **Mapping witness (conversion milestone):** the conversion command
+   and the mode read command each have their
+   `tool-gateway-mapping.md` row (added by amendment per §2.2/§4.4)
+   before the commands ship.
+
+## Ruling request
+
+Ratify sections 1–6 as written, with one decision embedded:
+
+- Decision (§5): v1 implements the **mode record and its immutability
+  only** — bootstrap records `standalone`, the `enterprise` value is
+  reserved and refused, and the conversion command itself is deferred
+  to the Enterprise milestone, consistent with D11's deferred list.
+  v1 carries three obligations beyond the record: the closed writer
+  assertion, the D14 column boundary, and the unknown-value refusal
+  (§6.1–§6.3) — these are the non-foreclosure floor, not hidden
+  conversion work. Alternative if rejected: build the conversion
+  command inside v1 — rejected because D11 scopes v1 to the Standalone
+  slice and conversion depends on contract 7 custody mechanics that
+  are themselves not in the v1 slice.

+## 8. Amendment A1 — hierarchy parentage and RBAC chain above workspaces
+
+**Status:** amendment to the ratified canon, added by reviewed PR under
+decision D13 (operator ruling, 2026-08-25; decision owner Jason). It adds
+parent structure ABOVE workspaces. Sections 1–7, every invariant in §3, and
+every REQ above remain binding verbatim, with exactly one express modification:
+the narrow portfolio-analytics carve-out stated in §8.2.4. Nothing else below
+this line is weakened.
+
+### 8.1 What is added
+
+1. A platform hierarchy exists above workspaces:
+   **company/organization → estate → platform-project → workspace**. Each
+   workspace belongs to exactly one platform-project, each platform-project to
+   exactly one estate, each estate to exactly one company.
+2. **Record class.** Hierarchy records (company, estate, platform-project,
+   their parentage edges, and hierarchy-level access grants) are a new,
+   explicitly named record class: **tenancy/authorization structure records**.
+   They are not business or orchestration records, so §3 invariant 10 and
+   REQ-TEN-001 do not apply to them and are not weakened by them — those two
+   requirements bind business/orchestration rows exactly as before.
+   Constraints on the new class:
+   - Hierarchy tables MUST NOT carry task, plan, or any other
+     business/orchestration payload — parentage, naming, and grant data only.
+   - A hierarchy record can never be the subject of work: it cannot be
+     claimed, ordered, gated, or referenced as a dependency by any
+     business/orchestration row.
+   - Hierarchy mutations flow through the same sole-writable-SOT, fail-closed,
+     audited mutation path as everything else (§8.2.3).
+3. The hierarchy serves exactly two runtime functions, plus audited
+   maintenance of its own structure:
+   - **RBAC evaluation:** access grants are declared per company, estate, or
+     platform-project and evaluate down the chain to workspace-scoped
+     authorization. Tenant context continues to be derived from authenticated
+     authority (REQ-TEN-001); the chain adds where grants can be declared,
+     not a bypass of workspace authorization.
+   - **Read-only roll-ups:** task and status visualization bubbles up the
+     hierarchy as aggregation over workspaces the reader is authorized on.
+   - **Chain maintenance (not a third runtime function):** re-parenting an
+     asset — moving a workspace to another platform-project, a
+     platform-project to another estate, and so on ("assets are transferable
+     subject to the structure", PRD Part I §4) — is an audited edit of the
+     hierarchy records themselves under §8.3. It never modifies
+     business/orchestration rows and never crosses a workspace boundary for
+     them; the workspace's contents move with the workspace untouched.
+4. Naming: this amendment says **platform-project** for the hierarchy level
+   above workspaces, because §5 REQ-PLAN-001 already defines `projects` as
+   planning entities INSIDE a workspace. The two are different objects. Final
+   terminology (rename of one or the other) is an implementation-PR decision
+   under this amendment's review; the schema MUST NOT merge them.
+
+### 8.2 What is explicitly unchanged
+
+1. `workspace_id` remains the hard mechanical isolation unit (§2 D2,
+   REQ-TEN-001). Hierarchy tables carry parentage; they do not create
+   cross-workspace relationships between business/orchestration rows, which
+   remain rejected (§3 invariant 10).
+2. Roll-up is **never a write**: no aggregation path may mutate, claim, order,
+   or gate work in any workspace. Bubble-up views are generated projections in
+   the sense of §3 invariant 5 — non-authoritative and never import sources.
+3. Fail-closed mutation health (§3 invariants 3–4), sole writable PostgreSQL
+   SOT, fencing, audit, and the Coordinator/Certifier authority rules are
+   untouched.
+4. No §6 non-goal is authorized, with one express, narrow carve-out that this
+   amendment makes to the "portfolio analytics" non-goal: the read-only
+   roll-up of §8.1 — per-workspace task counts and statuses aggregated up the
+   parent chain, over workspaces the reader is authorized on — is in scope.
+   Everything beyond that boundary (metrics, trends, forecasting, scoring,
+   dashboards computed across workspaces, any derived analytic that is not a
+   direct count/status aggregation) remains a non-goal. This is an explicit
+   narrowing by amendment, not a claim that §6 is unchanged; every other §6
+   non-goal is untouched.
+
+### 8.3 Acceptance (binding on the implementing PRs)
+
+- Schema tests prove each workspace resolves to exactly one
+  platform-project/estate/company chain and that chain edits are audited.
+- Authorization tests prove a grant at each hierarchy level yields exactly the
+  workspace permissions the chain implies, and that revocation up the chain
+  propagates.
+- Negative tests prove roll-up endpoints cannot mutate state and that a
+  reader sees aggregates only over workspaces they are authorized on
+  (no cross-tenant existence oracles).

+# Gitea repository via an org team (default: fleet-reviewers).
+#
+# Usage: grant-reviewer.sh -u <user> [-r <owner>/<repo>] [-t <team>]
+#
+# The team carries `permission: read` with per-unit overrides
+# {repo.code: read, repo.issues: write, repo.pulls: write}: the reviewer can
+# read code and write issues/PR reviews, but cannot push. The grant is
+# idempotent — the team is looked up before it is created, and member/repo
+# additions are PUTs.
+#
+# KNOWN LIMITATION — branch protection counts these reviews as UNOFFICIAL.
+# Gitea computes a review's `official` flag at SUBMISSION time, from write
+# permission on the repo or from membership in the protected branch's
+# approvals whitelist (disabled by default). A team granted through this
+# script has read permission on code, so under branch protection with
+# required_approvals the reviewer's approval shows but does NOT count toward
+# the required total — the merge still fails with "not enough approvals".
+# Enabling the approvals whitelist and adding this team to it is review
+# policy (who counts as an official approver), an operator decision made in
+# the repo's branch-protection settings, deliberately NOT automated here.
+# Because `official` is fixed at submission, whitelisting after the fact
+# requires the review to be re-submitted before it counts.
+#
+# Platform: Gitea only. On a GitHub-remoted repo this script refuses to run —
+# GitHub review access is granted through collaborator/team facilities that
+# have no equivalent to Gitea's org-team unit map.
+#
+# Identity: the acting credential resolves exactly as in issue-comment.sh —
+# GITEA_LOGIN (when set) names a tea login whose token MUST resolve for the
+# remote host (fail closed, never downgrade to the host default identity);
+# otherwise the per-seat identity ladder in detect-platform.sh applies
+# (MOSAIC_GIT_IDENTITY / git config mosaic.gitIdentity → per-slot token,
+# fail-loud on fleet hosts). Managing org teams requires org owner/admin:
+# an HTTP 403 from any step is reported as "org admin required on <org>",
+# never as a silent partial grant.
+#
+# Verification is fail-closed: after the member and repo PUTs, the script
+# GETs the single resources back (GET /teams/{id}/members/{user} and
+# GET /teams/{id}/repos/{owner}/{repo}) and refuses to report success unless
+# both confirm the grant. A PUT that returns success without persisting
+# (the #865 defect class: an exit code is not evidence of a durable write)
+# therefore fails the run instead of reporting a grant that does not exist.

+# Regression harness for grant-reviewer.sh (#1415): org-team reviewer grant
+# with fail-closed read-back verification.
+#
+# This harness models a REAL server: the curl stub keeps persistent team/
+# member/repo state on disk, the POST actually CREATES and PERSISTS the team,
+# the member/repo PUTs persist (except in the sabotage modes), and the
+# read-back GETs answer from that same state. There is no fabricated record
+# for the wrapper to "find" — verification passes only if the PUTs genuinely
+# persisted what the read-back retrieves. It proves the wrapper:
+#   1. creates the team with the EXACT reviewer payload (permission: read,
+#      units_map {repo.code: read, repo.issues: write, repo.pulls: write}) —
+#      the stub rejects any other payload;
+#   2. is idempotent: an existing team is found by EXACT name (a decoy team
+#      whose name merely CONTAINS the wanted name is listed first and must
+#      not be matched) and no create POST is issued;
+#   3. refuses to run against a GitHub-remoted repo (Gitea only);
+#   4. refuses when the owner is not an organization;
+#   5. maps HTTP 403 to "org admin required on <org>" and stops before any
+#      partial grant;
+#   6. fails closed when the member PUT returns 204 without persisting (the
+#      #865 defect class: an exit code is not evidence of a durable write);
+#   7. fails closed when the repo PUT returns 204 without persisting;
+#   8. with GITEA_LOGIN set, performs EVERY request under that login's token
+#      (never the host default), and with an UNRESOLVABLE GITEA_LOGIN fails
+#      closed with ZERO API calls instead of downgrading;
+#   9. never lets the bearer token ride in curl argv (curl --config only);
+#  10. leaves no temp files behind on success or failure paths.
