Stale/max-wait takeover was not safe against concurrent breakers: two
breakers could both judge the lock stale and both proceed, re-introducing
the tight-loop. POSIX/Node has no content- or inode-conditional unlink or
rename, so "judge stale, then replace" can never be atomic with pure path
ops.
Serialize ALL lock transitions (acquire, release, takeover) under one
short-lived registry mutex held only across a few fs ops, never across the
restart itself. This makes check-then-mutate atomic, so exactly one breaker
can take over a stale lock while the others wait and re-evaluate.
The mutex itself uses mtime-based staleness (open('wx') creates an empty
inode before the token is written; a content check would reap a lock that is
still being acquired). The mutex populates-or-cleans-up on write failure so a
half-created mutex never leaks.
Regression coverage at two widths: a 2-breaker barrier test (exactly one
takes over, the other waits) and the existing 3-breaker test (maxActive===1,
distinct tokens, final lock released).

Addresses the reviewer's blocker (comment 15915): release() unconditionally
unlinked restart.lock, so after a stale/max-wait break an OLD owner could
delete a NEWER owner's lock, letting a third restart interleave and defeating
the guard.
- Each acquire writes a unique owner token (randomUUID) into the lock file.
- release() only unlinks while that token is still on disk; once another caller
has broken and re-owned the lock, the timed-out original owner's release() is
a no-op and leaves the new owner's lock intact.
- Breaking a stale/timed-out lock now takes ownership atomically via
write-temp + rename (atomic replace) instead of a blind unlink-then-recreate;
a breaker that loses a concurrent takeover reads back a foreign token and
keeps waiting rather than assuming ownership.
Regression test (does not let a timed-out owner drop a lock another restart
broke and re-owned) reproduces the three-restart interleave: R1 hangs (stale),
R2 breaks + re-owns, R1.release() must NOT drop R2's lock. Fails on the old
blind-unlink path (ENOENT), passes now. Also adds explicit single-agent
restart-path guard coverage (review should-fix).

`mosaic fleet restart` runs as a fresh process each invocation, issuing
`systemctl --user restart` for the tmux holder and then each agent. The
agent sessions live inside the holder's tmux, so restarting the holder
tears them down. With no mutual exclusion, a second restart entering
while the first is still mid-teardown (upgrade `--relaunch`, a watchdog,
or a hurried operator) interleaves: agents relaunch against a
half-torn-down holder, fail, and tight-loop.
Add a cross-process teardown-settle guard: a lock file under
`<mosaicHome>/fleet/run/restart.lock` acquired with O_CREAT|O_EXCL.
A re-entrant restart waits (bounded, injectable sleep) for the in-flight
restart to release the lock before relaunching, breaks a stale lock left
by a crashed owner, and after a max wait breaks the lock to avoid a
permanent deadlock. Both full-fleet and single-agent restart paths are
guarded; start/stop/status are unchanged.
Regression test reproduces the race: with an in-flight lock held, the
restart must wait before issuing any systemctl command — fails on the
unguarded code path, passes with the guard. Adds stale-lock-break and
lock-release coverage.

- CRIT-1: Validate cert subjectUserId against grant.subjectUserId from DB;
use authoritative DB value in FederationContext
- CRIT-2: Add @Inject(GrantsService) decorator (tsx/esbuild requirement)
- HIGH-1: Validate UTF8String TLV tag, length, and bounds in OID parser
- HIGH-2: Collapse all 403 wire messages to a generic string to prevent
grant enumeration; keep internal logger detail
- HIGH-3: Assert federation wire envelope shape in all guard tests
- HIGH-4: Regression test for subjectUserId cert/DB mismatch
Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
Adds FederationAuthGuard that validates inbound mTLS client certs on
federation API routes. Extracts custom OIDs (grantId, subjectUserId),
loads the grant+peer from DB in one query, asserts active status, and
validates cert serial as defense-in-depth. Attaches FederationContext
to requests on success and uses federation wire-format error envelopes
(not raw NestJS exceptions) for 401/403 responses.
New files:
- apps/gateway/src/federation/oid.util.ts — shared OID extraction (no dupe ASN.1 logic)
- apps/gateway/src/federation/server/federation-auth.guard.ts — guard impl
- apps/gateway/src/federation/server/federation-context.ts — FederationContext type + module augment
- apps/gateway/src/federation/server/index.ts — barrel export
- apps/gateway/src/federation/server/__tests__/federation-auth.guard.spec.ts — 11 unit tests
Modified:
- apps/gateway/src/federation/grants.service.ts — adds getGrantWithPeer() with join
- apps/gateway/src/federation/federation.module.ts — registers FederationAuthGuard as provider

- HIGH-A: resolveEntry now uses promise-cache pattern so concurrent
callers serialize on a single in-flight build, eliminating duplicate
key material in heap and duplicate DB round-trips
- HIGH-B: flushPeer destroys the evicted undici Agent so stale TLS
connections close on cert rotation
- MED-C: add regression test for PEER_MISCONFIGURED when
STEP_CA_ROOT_CERT_PATH is unset
Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
CRIT-1: regenerate pnpm-lock.yaml so apps/gateway resolves [email protected].6
(prior PR pushed package.json without lockfile update; CI failed with
ERR_PNPM_OUTDATED_LOCKFILE). Incidentally cleans 57 lines of stale
peer-dep entries.
CRIT-2: cache-hit test no longer swallows resolveEntry errors. Calls the
private method directly twice and asserts identity equality plus a
single DB select, removing the silent-failure path the prior assertion
allowed.
HIGH-1: mTLS Agent now pins Step-CA root via STEP_CA_ROOT_CERT_PATH.
Without the env var resolveEntry throws PEER_MISCONFIGURED, refusing to
dial peers against the public trust store. PEM is read once and cached
on the service instance.
Co-Authored-By: Claude Opus 4.7 <[email protected]>
Implements FederationClientService — a NestJS injectable that dials peer
gateways over mTLS (undici Agent with cert+sealed-key from federation_peers),
invokes list/get/capabilities verbs, validates responses via Zod, and surfaces
all failure modes as typed FederationClientError with a coherent error code
taxonomy (PEER_NOT_FOUND, PEER_INACTIVE, PEER_MISCONFIGURED, NETWORK,
FORBIDDEN, HTTP_{status}, INVALID_RESPONSE).
Per-peer Agent instances are cached in a Map for the service lifetime;
flushPeer(peerId) invalidates the cache for M5/M6 cert rotation and
revocation events.
Wired into FederationModule providers + exports so QuerySourceService
(M3-09) can inject it.
13 unit tests covering all required scenarios via undici MockAgent +
real sealClientKey/unsealClientKey round-trip.

Picks up auth command and spec written by parallel agent, and updated
mosaic cli.ts wiring from parallel development during cli-unification.
Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
Adds mosaic forge run|status|resume|personas list subcommands to
@mosaicstack/forge, wires registerForgeCommand into the root mosaic CLI,
and ships a smoke test asserting command structure. Ref CU-05-01
cli-unification-20260404.

- Remove @mosaicstack/cli (absorbed into @mosaicstack/mosaic)
- Add all 21 remaining workspace packages so the multi-package
update checker actually covers every published package
@mosaic/mosaic is now the single package providing both:
- 'mosaic' binary (CLI: yolo, coord, prdy, tui, gateway, etc.)
- 'mosaic-wizard' binary (installation wizard)
Changes:
- Move packages/cli/src/* into packages/mosaic/src/
- Convert dynamic @mosaic/mosaic imports to static relative imports
- Add CLI deps (ink, react, socket.io-client, @mosaic/config) to mosaic
- Add jsx: react-jsx to mosaic's tsconfig
- Exclude packages/cli from workspace (pnpm-workspace.yaml)
- Update install.sh to install @mosaic/mosaic instead of @mosaic/cli
- Bump version to 0.0.17
This eliminates the circular dependency between @mosaic/cli and
@mosaic/mosaic that was blocking the build graph.
git pull --rebase fails with 'cannot pull with rebase: You have
unstaged changes' when the skills repo has local modifications.
Fix: detect dirty index/worktree, stash before pull, restore after.
Also gracefully handle pull failures (warn and continue with existing
checkout) and stash pop conflicts.
Two bugs causing 'EACCES: permission denied, copyfile' when source
and target are the same path (e.g. wizard with sourceDir == mosaicHome):
1. No same-path guard — syncDirectory tried to copy every file onto
itself; git pack files are read-only (0444) so copyFileSync fails.
2. excludeGit only matched top-level .git — nested .git dirs like
sources/agent-skills/.git were copied, hitting the same permission
issue.
Fixes:
- Early return when resolve(source) === resolve(target)
- Match .git dirs at any depth via dirName and relPath checks
- Skip files inside .git/ paths
Added file-ops.test.ts with 4 tests covering all cases.
- mosaic-init bash script: detect existing SOUL.md/USER.md/TOOLS.md and
prompt user to keep, import (re-use values as defaults), or overwrite.
Non-interactive mode exits cleanly unless --force is passed.
Overwrite creates timestamped backups before replacing files.
- launch.ts checkSoul(): prefer 'mosaic wizard' over legacy bash script
when SOUL.md is missing, with fallback to mosaic-init.
- detect-install.ts: pre-populate wizard state with existing values when
user chooses 'reconfigure', so they see current settings as defaults.
- soul-setup.ts: show existing agent name and communication style as
defaults during reconfiguration.
- Added tests for reconfigure pre-population and reset non-population.
The #351 merge landed before the force-push with full commands.
This adds the missing subcommands:
- mosaic coord {init,status,mission,continue,run,smoke,resume}
→ delegates to tools/orchestrator/*.sh with --claude/--codex/--pi/--yolo
- mosaic prdy {init,update,validate,status}
→ delegates to tools/prdy/*.sh with --claude/--codex/--pi
- mosaic seq {check,fix,start}
→ sequential-thinking MCP management (native TS)
- mosaic upgrade {release,check,project}
→ delegates to tools/_scripts/mosaic-release-upgrade and mosaic-upgrade
Also removes duplicate prdy registration (was in both launch.ts and
the old registerPrdyCommand — now only in launch.ts).
Templates moved from packages/mosaic/templates/ to
packages/mosaic/framework/templates/ in #345. The test's
existsSync guard silently skipped the copy, causing writeSoul
to early-return without writing SOUL.md.
The @mosaic scope registry is configured in ~/.npmrc. Passing --registry
on the install command overrides the default registry for ALL packages,
causing non-@mosaic deps like @clack/prompts to 404 against Gitea.
The insights table uses vector(1536) but no migration enables the pgvector
extension. CI postgres (pgvector/pgvector:pg17) has the extension available
but it must be explicitly created before use.
Adds CREATE EXTENSION IF NOT EXISTS vector at the top of
0001_cynical_ultimatum.sql (the first migration referencing vector type).
The migration file 0001_cynical_ultimatum.sql existed on disk but was not
registered in the Drizzle journal (_journal.json). This caused fresh-database
migrations (CI) to skip creating tables (agent_logs, insights, preferences,
skills, summarization_jobs), then 0002_nebulous_mimic.sql would fail trying
to ALTER the non-existent preferences table.
Fix: insert cynical_ultimatum at idx 1 in the journal and shift all
subsequent entries (idx 2-7).
Verified: pnpm test passes (347 tests, 35 tasks).
