feat(framework): P1+P2 — public sanitization + blocking CI gate

Adds tools/quality/scripts/verify-sanitized.sh (two-class, self-tested) wired
blocking in .woodpecker/ci.yml; sanitizes operator identity from the public
framework package so the gate is green.

- purge jarvis/jason/woltje/PDA across 26 files -> generic
- delete jarvis-loop.json overlay; add neutral examples/{personas,overlays}
- relocate maintainer AUDIT to docs/audits/; delete 2 jarvis-brain rule blocks
- neutralize SOUL persona; strip "(Policy: Jason ...)" keeping universal rule
- test fixtures jason.woltje -> ci-bot (both git tests pass)

Deferred (tracked): private third-party host (uscllc) genericization.

Refs #542, closes #571

+# Local Fleet Canary
+
+The local fleet canary runs a small tmux-backed Mosaic agent fleet on an
+isolated tmux socket. The default socket is `mosaic-factory`; the commands do
+not use or stop the default tmux server.
+
+## Files
+
+Product-owned defaults:
+
+- `packages/mosaic/framework/fleet/roster.schema.json`
+- `packages/mosaic/framework/fleet/examples/minimal.yaml`
+- `packages/mosaic/framework/fleet/examples/local-canary.yaml`
+- `packages/mosaic/framework/systemd/user/mosaic-tmux-holder.service`
+- `packages/mosaic/framework/systemd/user/mosaic-agent@.service`
+- `packages/mosaic/framework/tools/fleet/start-agent-session.sh`
+- `packages/mosaic/framework/tools/tmux/agent-send.sh`
+- `packages/mosaic/framework/tools/tmux/send-message.sh`
+
+These files are published through `packages/mosaic/package.json`, whose `files`
+allowlist includes `framework` along with `dist`.
+
+Site-owned local roster:
+
+```text
+~/.config/mosaic/fleet/roster.yaml
+```
+
+Do not put a host-specific full roster into product defaults. Start from an
+example and edit the local roster after `mosaic fleet init --write`.
+
+## Install
+
+Minimal canary:
+
+```bash
+mosaic fleet init --profile minimal --write
+# If a site-owned roster already exists, inspect it first; overwrite only explicitly:
+# mosaic fleet init --profile minimal --write --force
+mosaic fleet install-systemd
+systemctl --user daemon-reload
+mosaic fleet start
+mosaic fleet verify
+```
+
+Small dogfood roster:
+
+```bash
+mosaic fleet init --profile local-canary --write
+# Use --force only after preserving any site-owned roster changes.
+mosaic fleet install-systemd
+systemctl --user daemon-reload
+mosaic fleet start
+mosaic fleet status
+```
+
+## Agent Operations
+
+```bash
+mosaic agent roster
+mosaic agent status
+mosaic agent status canary-pi
+mosaic agent send canary-pi --message "status check"
+mosaic agent reset canary-pi --new
+mosaic agent tail canary-pi -n 80
+```
+
+These commands read the roster and target the configured tmux socket. The
+generated systemd agent services use `start-agent-session.sh`; message delivery
+uses the tmux send tools with `-L mosaic-factory`.
+
+`mosaic agent send` is operator-origin traffic unless a caller explicitly says
+otherwise. The CLI always passes a deterministic source label to
+`agent-send.sh` with `-S`, defaulting to `<hostname>:operator`, so it does not
+query the target tmux socket and accidentally identify as an active agent pane.
+Use `--source-label <label>` or `--source <label>` only when deliberately
+impersonating a known handoff lane. The lower-level inter-agent wrapper
+`agent-send.sh -S <label>` remains the explicit source override for scripts.
+
+## Verification
+
+Use these checks before expanding the roster:
+
+```bash
+tmux -L mosaic-factory ls
+tmux ls
+mosaic fleet verify
+systemctl --user status mosaic-tmux-holder.service
+```
+
+Expected results:
+
+- `tmux -L mosaic-factory ls` shows `_holder` and roster agent sessions.
+- `tmux ls` shows only the default tmux server sessions and is not changed by
+  fleet start/stop operations.
+- `mosaic fleet verify` checks exact session targets on the isolated socket.
+- `systemctl --user status ...` may show `active (exited)` for oneshot units;
+  that means the unit ran, not that an agent pane is live. Treat tmux
+  `has-session`, `list-panes`, process tree, and logs as the liveness evidence.
+
+## Release Preflight
+
+Run this checklist before cutting or dogfooding a fleet release:
+
+- Real AI dogfood: send at least one task through `mosaic agent send`, then
+  confirm the agent accepted/responded using pane, process, or log evidence.
+- Restart/stop/idempotency: run `mosaic fleet start`, `restart`, `stop`, and a
+  repeated `start` against the named socket; verify the default tmux server is
+  unchanged.
+- Liveness verification: run `mosaic fleet verify` and confirm roster sessions
+  with `tmux -L mosaic-factory ls` or exact `has-session` checks.
+- Package dry-run: run `npm pack --dry-run --json` from `packages/mosaic` and
+  confirm `framework/fleet`, `framework/systemd/user`,
+  `framework/tools/fleet`, and `framework/tools/tmux` assets are included.
+- Mosaic update test: install or upgrade from the packed artifact in a temporary
+  Mosaic home and confirm `mosaic update` or the release upgrade path does not
+  remove local roster/config files.
+
+## Rollback
+
+Stop the local canary:
+
+```bash
+mosaic fleet stop
+systemctl --user disable mosaic-agent@canary-pi.service
+systemctl --user disable mosaic-tmux-holder.service
+systemctl --user daemon-reload
+```
+
+For a full local cleanup of generated canary files:
+
+```bash
+rm -f ~/.config/systemd/user/mosaic-agent@.service
+rm -f ~/.config/systemd/user/mosaic-tmux-holder.service
+rm -rf ~/.config/mosaic/fleet
+rm -rf ~/.config/mosaic/tools/fleet
+```
+
+This rollback leaves the default tmux server untouched. If a canary session is
+still present after service stop, remove only the isolated socket server:
+
+```bash
+tmux -L mosaic-factory kill-server
+```

+# Fleet CLI Local Canary Dogfood — 2026-06-20
+
+## Objective
+
+Move the durable tmux fleet PoC into a functional local canary on this server. This is **not** production deployment. It is a canary/dogfood path for a small local agent fleet using an isolated tmux socket.
+
+## Issue
+
+- Gitea issue: #562 — `feat(fleet): local CLI canary dogfood`
+
+## Scope
+
+Implement enough product surface to use the fleet locally:
+
+- `mosaic fleet init/install/start/stop/restart/status/verify`
+- `mosaic agent roster/status/send/reset/tail`
+- roster schema and examples
+- local canary docs and rollback instructions
+- tests for CLI behavior where practical
+- canary verification on named tmux socket `mosaic-factory`
+
+## Non-goals
+
+- No production rollout.
+- No migration of existing default tmux sessions.
+- No image build/deploy work.
+- No hardcoded USC/local roster as product default.
+
+## Acceptance Criteria
+
+- CLI can initialize a minimal roster outside product defaults.
+- CLI can install user systemd units and fleet helper scripts to a configurable Mosaic home.
+- CLI can start/stop/status/verify a canary fleet using `mosaic-factory`.
+- `mosaic agent send` uses existing named-socket/exact-target tmux tooling.
+- `mosaic agent reset` targets only the named agent session on the named socket.
+- Verification proves default tmux sessions remain untouched.
+- Baseline repo gates pass.
+- PR CI is green before merge.
+- Local canary evidence is captured after merge/install.
+
+## Budget / Routing
+
+- Agent: codex preferred.
+- Estimate: 25K-40K tokens.
+- Worker owns implementation/tests/docs in branch `feat/fleet-cli-local-canary`.
+- Orchestrator owns `docs/TASKS.md`, issue/PR/merge, and local canary install verification.
+
+## Progress
+
+- 2026-06-20: #557 PoC primitives merged to `main` as `45e2c2a`.
+- 2026-06-20: issue #562 created for local CLI canary dogfood.
+- 2026-06-20: worktree created at `/home/jarvis/src/mosaicstack-stack-worktrees/fleet-cli-local-canary`.

+# Fleet release hardening
+
+## Objective
+
+Harden the Mosaic local fleet release path for operator sends, tmux/systemd verification, package contents, and dogfood release documentation.
+
+## Constraints
+
+- Do not edit `docs/TASKS.md`.
+- Do not change production deployment refs.
+- Keep fleet transport generic and named-socket safe.
+- Preserve strict roster validation.
+- Add tests first or alongside fixes.
+
+## Plan
+
+1. Add regression tests for deterministic `mosaic agent send` source labels.
+2. Strengthen fleet status/verify/package/install-systemd coverage.
+3. Implement focused CLI/source-label changes.
+4. Update local canary documentation with dogfood preflight.
+5. Run formatting, targeted tests, typecheck, lint, and package dry-run evidence.
+
+## Evidence Log
+
+- Started from existing `docs/PRD.md`; durable local fleet canary is in v0.1.0 scope.
+- Loaded `mosaic-fleet-operations` skill; key constraints are isolated tmux sockets, no default tmux positive tests, and `active (exited)` is not liveness.
+- TDD red: `pnpm --filter @mosaicstack/mosaic test -- src/commands/fleet.spec.ts` initially failed because `node_modules` was absent; after `pnpm install`, the new source-label tests failed on missing `-S`, missing helper, and unknown `--source-label`.
+- Green implementation: `mosaic agent send` now passes `-S <hostname>:operator` by default and accepts `--source-label` / `--source` overrides.
+- Test coverage added for tmux-based fleet verify liveness, package `files` allowlist containing `framework`, and explicit operator source-label command construction.
+- Formatting: `pnpm exec prettier --write packages/mosaic/src/commands/fleet.ts packages/mosaic/src/commands/fleet.spec.ts docs/guides/fleet-local-canary.md docs/scratchpads/2026-06-20-fleet-release-hardening.md`.
+- Targeted tests: `pnpm --filter @mosaicstack/mosaic test -- src/commands/fleet.spec.ts src/cli-smoke.spec.ts` passed with 49 tests.
+- Typecheck: `pnpm typecheck` passed.
+- Lint: `pnpm lint` passed.
+- Package dry-run: `npm pack --dry-run --json` from `packages/mosaic` included `framework/fleet`, `framework/systemd/user`, `framework/tools/fleet/start-agent-session.sh`, and `framework/tools/tmux/{agent-send.sh,send-message.sh}`.
+- Review: `~/.config/mosaic/tools/codex/codex-code-review.sh --uncommitted` approved the supplied diff with no findings; the review tool noted its read-only sandbox could not inspect files directly.

+# Fleet CLI Local Canary Review Fixes
+
+## Objective
+
+Fix only the two should-fix code review findings:
+
+1. Ensure `@mosaicstack/mosaic` declares `yaml` and lockfile state is current.
+2. Validate `mosaic agent status [agent]` against the fleet roster before constructing/running the tmux target.
+
+## Constraints
+
+- Do not modify `docs/TASKS.md`.
+- Leave changes uncommitted.
+- Run requested formatting and quality gates.
+
+## Plan
+
+1. Inspect manifest/lockfile state for `yaml`.
+2. Add failing regression test for `mosaic agent status typo`.
+3. Patch `registerFleetAgentCommands` status validation.
+4. Format touched files.
+5. Run requested tests, typecheck, and lint.
+6. Review final diff.
+
+## Progress
+
+- Loaded required repo/global/runtime instructions.
+- Confirmed `packages/mosaic/package.json` already declares `yaml`.
+- Confirmed `pnpm-lock.yaml` already has `packages/mosaic` importer entry for `yaml`.
+- Found `registerFleetAgentCommands` status path does not validate agent before building tmux target.
+
+## Verification
+
+- TDD red check: `pnpm --filter @mosaicstack/mosaic test -- src/commands/fleet.spec.ts`
+  failed before the production fix because `mosaic agent status typo` resolved instead of
+  rejecting.
+- Focused green check: `pnpm --filter @mosaicstack/mosaic test -- src/commands/fleet.spec.ts`
+  passed after adding roster validation.
+- Formatting: `pnpm exec prettier --write packages/mosaic/src/commands/fleet.ts packages/mosaic/src/commands/fleet.spec.ts docs/scratchpads/fleet-cli-local-canary-review-fixes.md`
+  completed with all files unchanged.
+- Requested tests: `pnpm --filter @mosaicstack/mosaic test -- src/commands/fleet.spec.ts src/cli-smoke.spec.ts`
+  passed with 36 tests.
+- Baseline typecheck: `pnpm typecheck` passed.
+- Baseline lint: `pnpm lint` passed.
+- Independent review: `~/.config/mosaic/tools/codex/codex-code-review.sh --uncommitted`
+  returned approve with 0 findings. Note: reviewer reported broader context inspection was limited
+  by its read-only sandbox, so review was based on the supplied diff.
+- `docs/TASKS.md` has no diff.
+
+## Risks
+
+- `docs/TASKS.md` intentionally untouched per user instruction.
+- Review finding 1 required no file edit: `packages/mosaic/package.json` already declares
+  `yaml`, and the `packages/mosaic` importer in `pnpm-lock.yaml` already includes `yaml`.

+# Mosaic Fleet Rosters
+
+The local fleet canary uses a product-owned roster schema with site-owned roster
+files. Product examples live here; active local rosters should live outside the
+package, normally at:
+
+```text
+~/.config/mosaic/fleet/roster.yaml
+```
+
+The default tmux socket is `mosaic-factory` so fleet commands do not touch the
+default tmux server.
+
+## Examples
+
+- `examples/minimal.yaml` starts one local canary slot.
+- `examples/local-canary.yaml` starts a small generic dogfood fleet.
+
+Initialize a roster:
+
+```bash
+mosaic fleet init --profile minimal --write
+mosaic fleet install-systemd
+mosaic fleet start
+mosaic fleet verify
+```

+# Two rule classes:

+#   2. DENYLIST    — a LABELED, one-time regression guard for the CURRENT operator's
+#                    identity tokens. This is NOT a general PII detector (a future
+#                    operator's name can't be enumerated); the durable control is the
+#                    L0 prose firewall + human review. This gate just stops *this*
+#                    contamination from coming back.
+#
+# Scope: all of the framework package — *.md, *.sh, *.ps1, and the CLI scripts under
+#        tools/_scripts/ (which are extensionless). Excluded: examples/ (holds
+#        sanitized, placeholdered worked examples), node_modules/, and this gate file.
+#
+# NOTE on scope: private THIRD-PARTY host references (e.g. a maintainer's employer
+# Gitea) are intentionally NOT in this denylist — they are functionally entangled in
+# host-routing + test fixtures and are tracked as a separate follow-up.
