+# Fleet Unattended First-Start Operations
+
+> **Status:** Current after issue #1264 lands. This runbook covers only Mosaic's first-run identity
+> gate; it does not install runtimes or credentials.
+
+## Operational contract
+
+A systemd fleet unit launches under a sanitized environment with no TTY. The generated environment
+sets `MOSAIC_AGENT_NAME`; Mosaic resolves that exact value against the canonical installed roster
+before writing identity files.
+
+If top-level identity contracts are missing, Mosaic atomically seeds them from the shipped generic
+sources:
+
+| Destination            | Source                          | New-file mode |
+| ---------------------- | ------------------------------- | ------------- |
+| `$MOSAIC_HOME/SOUL.md` | `$MOSAIC_HOME/defaults/SOUL.md` | `0600`        |
+| `$MOSAIC_HOME/USER.md` | `$MOSAIC_HOME/defaults/USER.md` | `0600`        |
+
+Creation is no-clobber and safe under concurrent seat starts. Existing regular files remain
+byte-for-byte and mode-for-mode unchanged. The runtime composer then injects the exact roster name
+and class; the generic source files grant no seat authority.
+
+## Failure handling
+
+The fleet path never falls back to an interactive wizard. It exits nonzero before runtime execution
+when:
+
+- `MOSAIC_AGENT_NAME` is not an exact roster member;
+- a defined ambient `MOSAIC_AGENT_CLASS` is blank/whitespace or disagrees with that member's
+  canonical class;
+- a missing destination has no safe regular default source;
+- a source or existing destination is a symlink (including dangling), directory, unavailable, or over the bounded size;
+- the fleet communications helper/roster cannot be validated; or
+- `USER.md` cannot be securely re-read at the point where its content is composed.
+
+Diagnostics begin with:
+
+```text
+[mosaic] ERROR: unattended fleet identity initialization failed: ...
+```
+
+Repair the exact named source, destination, roster, or helper and retry only that roster member. Do
+not delete or replace an existing personalized `SOUL.md`/`USER.md` merely to clear the check.
+
+## Verification without a live seat
+
+The source gate is:
+
+```bash
+pnpm --filter @mosaicstack/mosaic... build && \
+  pnpm --filter @mosaicstack/mosaic exec vitest run \
+    src/commands/launch-first-start.spec.ts
+```
+
+The build leg is load-bearing: `dist/` is ignored, so a direct Vitest invocation could otherwise run
+absent or stale CLI output. The gate runs the exact-source built CLI in subprocesses with piped stdin,
+temporary homes, a canonical fixture roster, fake runtime/broker executables, and no provider call. It
+covers no-TTY launch, exact identity,
+private modes, no-clobber, missing/symlink defaults, unknown members, blank/mismatched class,
+portable standalone composition/wizard preservation, and concurrent first start.
+
+Do not use this fixture as proof that a real provider credential is present or that a package has
+been deployed. Those require separate environment-specific evidence.

+# Fleet First-Start Identity Boundary
+
+> **Status:** Implemented by issue #1264. Requirements: `FCM-REQ-12`, `AC-FCM-10`.
+
+## Problem
+
+`launchRuntime()` called `checkSoul()` before runtime execution. A missing top-level `SOUL.md`
+caused `checkSoul()` to spawn a child `mosaic wizard` with inherited stdio. Under a systemd-created
+fleet pane with no TTY, that child blocked or failed before the runtime boundary even though generic
+`defaults/SOUL.md` and `defaults/USER.md` already shipped in the same `MOSAIC_HOME`.
+
+## Chosen boundary
+
+The fix remains at `checkSoul()` and does not add flags to `yolo`, fleet commands, systemd units, or
+`start-agent-session.sh`:
+
+1. A present, nonblank, whitespace-exact `MOSAIC_AGENT_NAME` selects the fleet path.
+2. `resolveFleetIdentity()` must resolve that exact member through the existing roster/helper
+   boundary, and any defined `MOSAIC_AGENT_CLASS` (including blank/whitespace) must canonicalize to
+   the roster class, before any identity seed. Only undefined means absent.
+3. `lstatSync()` preflights every destination directory entry without following links, so a dangling
+   link is rejected before its counterpart can be published.
+4. Safe bounded snapshots are read from only the missing contracts under `defaults/`.
+5. Each snapshot is written to a random owner-private temporary file in `MOSAIC_HOME`.
+6. `linkSync()` publishes the complete file without overwriting an existing path. `EEXIST` means a
+   concurrent seat or operator won; the existing path is preserved and revalidated.
+7. Temporary files are removed, and both installed contracts are re-opened through the no-symlink
+   secure-file reader before launch continues.
+8. `composeContract()` independently re-resolves the roster, securely reads fleet `USER.md` through
+   a Linux descriptor at the point of use, and injects exact member identity and communications data.
+
+A standalone launch with no `MOSAIC_AGENT_NAME` retains the portable tolerant USER read and the
+interactive wizard. Fleet-only no-follow enforcement must not make supported standalone macOS
+composition depend on Linux `/proc` descriptor traversal.
+
+## Identity and authority
+
+The copied defaults deliberately say “Mosaic agent”; they are a generic behavioral base. They are
+not the source of a fleet seat's identity. The canonical roster controls:
+
+- exact agent/session name;
+- canonical role/class and persona;
+- peer rows and point of contact;
+- tmux socket and helper target; and
+- communications generation.
+
+An unknown/padded ambient name, mismatched class, or explicitly blank/whitespace class fails before
+any file is seeded. This avoids replacing the interactive wall with a fleet of indistinguishable or
+ambiently invented identities.
+
+## Concurrency and filesystem properties
+
+- Sources and final destinations are bounded regular files beneath `MOSAIC_HOME`; target and dangling
+  symlinks are not followed.
+- New files have mode `0600`.
+- Hard-link publication is same-filesystem, atomic, and no-clobber.
+- A temporary path is removed only when this process successfully created it.
+- All required source snapshots are validated before the first destination is published, preventing
+  a missing second default from leaving a partial seed.
+- Existing operator files are never chmodded or rewritten.
+
+## Verification
+
+`src/commands/launch-first-start.spec.ts` uses the production-kind boundary: the real built CLI in a
+no-TTY subprocess, not a direct wizard test. The package `test:vitest` gate builds Mosaic before
+Vitest, while the clean-checkout command builds its workspace dependencies first, so ignored
+`dist/cli.js` cannot be absent or stale. A fake lease launcher records whether execution reached the
+runtime boundary and captures the composed prompt.
+Positive and negative cases prove the check can both proceed and refuse. Fleet composition coverage
+replaces a previously validated `USER.md` with an external symlink and proves point-of-use refusal;
+a standalone unreadable-optional-USER case proves the portable tolerant branch remains separate.
+
+Real Pi authentication and provider task execution remain environment tests, not claims of this
+fixture.

+`FCM-REQ-11` is reserved by #1256's concurrent runtime-preflight delivery. This amendment therefore

+
+1. `FCM-REQ-12`: A roster-owned fleet launch SHALL NOT invoke an interactive identity wizard when

+   contracts from the shipped generic `defaults/` contracts without overwriting operator-owned
+   bytes. The canonical roster member remains the sole source of the seat's exact name and class;
+   generic defaults grant no fleet identity or authority. Missing or unsafe defaults SHALL fail
+   closed with actionable diagnostics before runtime execution. Non-fleet launches retain the
+   interactive identity flow.
+2. `AC-FCM-10`: A systemd-equivalent no-TTY test with a clean temporary Mosaic home SHALL prove a
+   named fleet seat reaches the runtime boundary without starting `mosaic wizard`, creates
+   byte-equal owner-private `SOUL.md` and `USER.md` seeds, and receives its exact roster name/class in
+   composed context. Tests SHALL also prove no-clobber behavior, concurrent/idempotent first start,
+   fail-closed invalid defaults, and preservation of the standalone interactive path.
+
+`ASSUMPTION:` `MOSAIC_AGENT_NAME` is the existing launch discriminator for roster-owned fleet
+processes. This amendment does not add a second fleet flag because generated fleet environments
+already set that value and the runtime composer independently resolves it against the canonical
+roster before execution.

+# Fleet Unattended First Start
+
+> **Status:** Current for roster-owned local fleet launches after issue #1264 lands. Runtime
+> installation and provider authentication remain separate prerequisites.
+
+A fleet seat started by systemd has no operator at its pane. On its first launch, Mosaic must not
+stop at the interactive identity wizard.
+
+## What happens on first start
+
+When `MOSAIC_AGENT_NAME` names an exact member of the installed fleet roster and top-level identity
+contracts are absent, the launcher:
+
+1. validates the exact roster member, its canonical class, and the installed fleet communications
+   helper;
+2. reads the shipped generic contracts from
+   `~/.config/mosaic/defaults/SOUL.md` and `defaults/USER.md`;
+3. creates only the missing top-level `SOUL.md` and `USER.md` as owner-private files;
+4. preserves any existing top-level identity file byte-for-byte; and
+5. launches the runtime with the roster member's exact agent/session name and role/class in composed
+   context.
+
+The generic defaults do **not** make every seat the same identity. They provide a shared behavioral
+base. The canonical roster row supplies each seat's exact name, class, peers, socket, and authority.
+
+## Operator behavior
+
+A normal standalone launch without a fleet identity retains its portable configuration path and still
+uses the interactive wizard when `SOUL.md` is absent:
+
+```bash
+mosaic pi
+```
+
+A roster-owned seat may be started without attaching to its pane:
+
+```bash
+mosaic fleet start <exact-roster-name>
+```
+
+Mosaic refuses before runtime execution if the requested member is absent, its explicitly supplied
+ambient class is blank or conflicts with the roster, a required default is missing or unsafe, or an existing identity contract
+is not a safe regular file. Repair the named component and retry the same exact roster member; do not
+copy another seat's personalized identity.
+
+## Separate prerequisites
+
+This behavior clears the Mosaic identity-wizard wall only. A clean host still needs:
+
+- the declared runtime installed on the pane PATH;
+- the fleet transport and generated unit assets; and
+- runtime/provider authentication appropriate to that seat.
+
+Those checks are separate so a successful identity bootstrap is not reported as a fully authenticated
+agent session.

+> Branch: `fix/1264-fleet-unattended-first-start` | Base:
+> `origin/next@476db12b92971634b67fd2057b7577ee5894e449`
+
+## Initial automated review
+
+Codex reviewed the pre-PR uncommitted delta with:
+
+```bash
+~/.config/mosaic/tools/codex/codex-code-review.sh --uncommitted \
+  -o /tmp/1264-codex-code-review.json
+```
+
+Result: `request-changes`, confidence `0.93`, 20 files, one should-fix. `checkSoul()` trimmed
+`MOSAIC_AGENT_NAME` for pre-seed resolution while composition used the original value, so a padded
+name could seed files before later refusal.
+
+Remediation rejected blank/leading/trailing-whitespace values before roster lookup or writes and
+added three built-CLI no-side-effect regressions. Automated re-review approved that delta with no
+findings (confidence `0.86`). Initial security review reported risk `none` (confidence `0.91`).
+
+## Formal exact-head review
+
+Daphne reviewed PR #1268 at exact head `43fa0477877e0d0f110da8d11c3033b40ddeb191` and filed Gitea
+review ID 168 as `REQUEST_CHANGES`. The review was source/PR-only; the canary remained untouched.
+
+Blocking groups:
+
+1. class mismatch was validated after first-start mutation;
+2. secure `USER.md` validation was discarded before ordinary path-following composition;
+3. `existsSync()` treated a dangling destination symlink as missing, allowing counterpart partial
+   publication; and
+4. the built-CLI/evidence chain allowed stale ignored `dist/`, cited an unshipped canary object, and
+   carried conflicting test totals/pane wording.
+
+The diagnostic's defaults-only repair advice was also inaccurate for roster/class/destination
+failures.
+
+## Formal-review remediation
+
+All four blocking groups received regressions before production changes. The RED run produced four
+failures while 1,568 existing tests passed. Remediation then:
+
+- validates canonical name and class before seeding;
+- preflights destination directory entries with `lstatSync()` so target and dangling symlinks fail
+  before publication;
+- securely reads `USER.md` through an `O_NOFOLLOW` descriptor at composition time;
+- adds a Mosaic build before package Vitest and a dependency build in the clean-checkout command;
+- replaces defaults-only advice with neutral named-component repair guidance; and
+- reconciles shipping canary provenance, pane chronology, commands, and totals.
+
+Remediation code review:
+
+```bash
+~/.config/mosaic/tools/codex/codex-code-review.sh --uncommitted \
+  -o /tmp/1264-remediation-code-review.json
+```
+
+Result: `approve`, confidence `0.88`, 6 files, no findings. Summary: the fail-closed destination
+checks, class-validation order, secure composition, and build-before-Vitest path are coherent.
+
+Remediation security review:
+
+```bash
+~/.config/mosaic/tools/codex/codex-security-review.sh --uncommitted \
+  -o /tmp/1264-remediation-security-review.json
+```
+
+Result: risk `none`, confidence `0.93`, 9 files, no critical/high/medium/low findings. The sandbox
+could not run Vitest because Vite attempted to create a temporary config artifact on its read-only
+mount (`EROFS`); executor-owned focused and full results are recorded in the QA report.
+
+## Second exact-head review
+
+Daphne reviewed exact head `9dc90be7e13b1cd609f6df97d43d890ef5392ca0` and filed Gitea review
+ID 169 as `REQUEST_CHANGES`. Review 169 confirmed all review-168 closures, then found:
+
+1. the new point-of-use reader was Linux-only but had been applied to every standalone USER read,
+   breaking supported non-fleet macOS composition; and
+2. explicit blank/whitespace `MOSAIC_AGENT_CLASS` was treated as absent and could seed before
+   runtime, while only undefined should mean absent.
+
+Red-first remediation preserves legacy `readOptional()` for standalone composition, keeps descriptor
+no-follow consumption fleet-only, moves the replacement-symlink case under a valid fleet identity,
+and rejects defined blank/whitespace classes before seeding. Three blank-class CLI cases and one
+tolerant standalone composition case failed before the source change and pass after it.
+
+Review-169 remediation code review approved at confidence `0.90` (4 files, no findings). Security
+review reported risk `none` at confidence `0.90` (4 files, no findings). The review sandbox retained
+its known Vite `EROFS` limitation; executor-owned tests are in the QA report.
+
+## Remaining review gate
+
+Daphne must re-review the next exact pushed head. This report cannot record that future verdict
+without changing the reviewed head, so the authoritative terminal verdict belongs to PR #1268's
+Gitea review record. Fred and goals are excluded as reviewers.

+# #1264 Unattended Fleet First-Start Verification
+
+> Status: **IN PROGRESS — review-169 remediation complete locally; push/re-review pending** |
+> Executor: goals | Date: 2026-08-16 | Target: isolated local fixtures only
+
+## Objective
+
+Verify that a named fleet seat launched through a systemd-equivalent, no-TTY environment on a clean
+host reaches its runtime boundary without an interactive Mosaic identity wizard. Preserve standalone
+wizard behavior and canonical-roster ownership of exact seat identity.
+
+## Source evidence accepted for local verification
+
+Daphne's canary Run-7 report is reachable from jarvis-brain `origin/main` at
+`8bf94afeb8c7d5df96cdd4a4508e75a1d2999710`,
+`docs/reports/2026-08-16_sbx-canary-greenfield-e2e.md`. The earlier local object
+`6c0b6fc70ae6a179a1b7ff9dedfc54e9adccd19a` is not reachable from an origin ref and is not used as
+shipping provenance. Run 7 measured:
+
+```text
+systemd -> start-agent-session.sh -> mosaic yolo pi (PID 3726)
+                                  -> child mosaic wizard (PID 3762)
+```
+
+The pane was preserved when Run 7 was captured. Formal review ID 168 records that an authorized
+rollback occurred later. This task never accessed or altered the canary VM, pane, snapshot, or
+rollback state. Product behavior is independently tested here with temporary roots and fake runtime
+executables.
+
+## Controls
+
+- Original base: `origin/next@476db12b92971634b67fd2057b7577ee5894e449`.
+- PR: #1268, first pushed head `43fa0477877e0d0f110da8d11c3033b40ddeb191`.
+- `DATABASE_URL` remains unset for local tests.
+- No runtime/provider credential or token value, VM, installed Mosaic tree, unit, timer, PATH profile,
+  or live tmux session is read or mutated. Standard Gitea/Woodpecker wrappers authenticate metadata
+  reads/writes without exposing credential values.
+- Tiny's runtime-preflight and `start-agent-session.sh` PATH work remain out of scope.
+- Held PR #1213 is not a dependency.

+
+## Initial RED
+
+Production source remained unchanged after adding the first reproducer. The CLI was built from
+`origin/next@476db12` before the test.
+
+```bash
+env -u DATABASE_URL pnpm --filter @mosaicstack/mosaic exec vitest run \
+  src/commands/launch-first-start.spec.ts
+```
+
+Exit `1`; one file and one test failed. Output included:
+
+```text
+[mosaic] SOUL.md not found. Running setup wizard...
+◆  What would you like to do?
+[mosaic] Setup failed. Run: mosaic wizard
+AssertionError: expected 1 to be +0
+```
+
+The fake runtime-boundary capture was not created. Complete stdout/stderr was retained at
+`/tmp/1264-red.out` during that work session.
+
+## Formal-review remediation RED
+
+Daphne's exact-head review ID 168 requested changes at `43fa0477`. Before changing production code,
+new regressions were run against an exact-source build. Four tests failed while the existing 1,568
+passed:
+
+1. valid roster name plus mismatched ambient class seeded both files before refusal;
+2. dangling `SOUL.md` allowed `USER.md` to be published before refusal;
+3. dangling `USER.md` allowed `SOUL.md` to be published before refusal; and
+4. replacing a securely validated `USER.md` with an external symlink was followed by composition.
+
+This establishes that all four review-168 findings were observable on the pushed implementation.
+
+Daphne's review ID 169 then found two more exact-head failures at `9dc90be7`. Before production
+changes, four new assertions failed:
+
+1. standalone composition routed an unreadable optional `USER.md` through the Linux-only descriptor
+   reader instead of the legacy portable tolerant path; and
+2. explicit `MOSAIC_AGENT_CLASS` values `""`, `" "`, and tab were treated as absent, seeded both
+   identity files, and reached runtime.
+
+The replacement-symlink case was also moved under a valid roster identity so it tests the fleet-only
+security boundary rather than standalone behavior.
+
+## Final GREEN
+
+The production-kind command builds Mosaic and all workspace dependencies before invoking Vitest,
+because `dist/` is ignored and may otherwise be absent or stale:
+
+```bash
+env -u DATABASE_URL sh -c '
+  pnpm --filter @mosaicstack/mosaic... build &&
+  pnpm --filter @mosaicstack/mosaic exec vitest run \
+    src/commands/fleet-first-start-identity.spec.ts \
+    src/commands/launch-first-start.spec.ts \
+    src/commands/launch.spec.ts \
+    src/commands/compose-contract.spec.ts \
+    src/config/file-adapter.test.ts \
+    src/cli-smoke.spec.ts
+'
+```
+
+Exit `0`: `6/6` files, `128/128` tests.
+
+- 15 real-CLI/no-TTY tests cover exact roster name/class, byte-equal `0600` seeds, no-clobber,
+  partial seed, missing/symlink defaults, unknown/padded/blank name, mismatched or explicitly blank
+  class, standalone wizard preservation, and four concurrent starts.
+- 12 direct filesystem tests cover complete publication, existing operators, idempotence, source
+  prevalidation, target and dangling destination links, invalid roots, oversized input, and
+  unexpected link errors.
+- Composition coverage deterministically replaces a valid fleet seat's validated `USER.md` with an
+  external symlink and requires refusal at point of use. A separate standalone case proves tolerant
+  optional composition remains outside the Linux-only fleet reader.
+
+Full package gate (which rebuilds Mosaic itself after the clean-checkout dependency build):
+
+```bash
+env -u DATABASE_URL pnpm --filter @mosaicstack/mosaic run test:vitest
+```
+

+
+Focused helper + point-of-use coverage:

+```text
+2 files, 53/53 tests
+Statements 97.84% | Branches 91.66% | Functions 100% | Lines 97.84%

+

+
+Pre-PR targeted shell runs on the unchanged shell surfaces also passed:

+```
+
+The aggregate local `test:framework-shell` run stopped at `invariant_r_unittest.py`: installed
+operator-global Pi is `0.84.2`, while the invariant is measured for `0.84.1`. Later aggregate stages
+remain unmeasured except the targeted suites above. Root `pnpm test` remains locally **UNTESTED**

+## CI evidence and external blocker
+
+Pipeline 2445 ran against exact first head `43fa0477`:
+
+- install, sanitization, upgrade guard, typecheck, lint, and format passed;
+- Mosaic Vitest passed `88/88`, `1,568/1,568`; and
+- the test step emitted exactly one `FAIL:` line:
+
+```text
+FAIL: host provides 'pi' in the system path; missing-binary cases are not measurable here
+```
+
+That line comes from the inherited `test-start-agent-session.sh` CI-fit guard, not #1264. Fred filed
+the correction as PR #1270. Its pipeline 2448 is terminal green and proves the four formerly masked
+suites execute, but #1270 is not merged, so `next` still carries the failing chain. A new #1268
+pipeline 2449 at `9dc90be7` reproduced the same single inherited `FAIL:` after Mosaic passed
+`1,573/1,573`. A new pipeline is pending the review-169 remediation push. Terminal-green #1268 CI is
+not claimed.
+
+PR #1268's envelope was read back as `user.login=mos-dt-0`; its commit is explicitly authored and

+
+## Objective
+
+A roster-owned fleet seat launched from systemd on a clean host must cross Mosaic's first-run identity
+gate without a human or TTY, while retaining exact name/class from the canonical roster and
+preserving the standalone interactive wizard.
+
+## Intake and boundaries
+
+- Shipping canary provenance is jarvis-brain `origin/main` commit

+  rollback. This task never accessed or altered the canary.
+- Tiny's concurrent runtime-preflight, `start-agent-session.sh`, and #1258 PATH seam remain untouched.
+- Held PR #1213 is not a dependency.
+- No runtime/provider credential values or provider calls, installed-host changes, PostgreSQL, unit,
+  timer, or profile mutation. Tests use temporary roots and fake executables only; Gitea/Woodpecker
+  metadata operations use standard wrappers without exposing credentials.
+
+## Requirements and design
+
+- PRD IDs: `FCM-REQ-12`, `AC-FCM-10`; `FCM-REQ-11` is reserved by #1256.
+- A present fleet name must be nonblank, whitespace-exact, and resolve through the canonical roster.
+- Any defined ambient class, including blank/whitespace, must canonicalize to the roster class before
+  mutation; only undefined means absent.
+- Preflight all destination directory entries with no-follow existence semantics so dangling links
+  fail before counterpart publication.
+- Seed only missing top-level files from bounded regular defaults with owner-private, atomic,
+  no-clobber hard links.
+- Generic defaults are behavior, not identity or authority.
+- Securely consume fleet `USER.md` through a Linux descriptor at composition time.
+- Standalone composition retains the portable tolerant USER read and missing identity retains the
+  wizard.
+

+
+## Test evidence
+
+### Initial RED
+
+The built `origin/next` CLI entered `mosaic wizard`, rendered `What would you like to do?`, exited 1,
+and never created the fake runtime-boundary capture.
+
+### Formal-review RED
+
+Against exact first-head production code, four new tests failed while 1,568 existing tests passed:
+class mismatch mutated before refusal; each dangling destination left its counterpart; and a
+replacement `USER.md` symlink was consumed by composition. Review-169 RED then proved standalone
+composition hit the Linux-only reader and three explicit blank/whitespace class cases seeded and
+launched.
+
+### Final local GREEN
+
+- Exact-source focused gate: `6/6` files, `128/128` tests.
+- Full exact-source Mosaic Vitest: `88/88` files, `1,577/1,577` tests.
+- Helper + point-of-use coverage: `53/53`; 97.84% statements/lines, 91.66% branches, 100% functions.
+- Root preflight passed; typecheck `45/45`, lint `25/25`, build `25/25`.
+- Initial targeted shell gates passed: start-agent-session, install migration `21/21`, init-RCE.
+- Local aggregate framework shell stops at operator-global Pi `0.84.2` versus measured `0.84.1`.
