## Substrate
The Mosaic Backlog is the backlog of record + dispatch engine, built on Mosaic's native Postgres storage service (@mosaicstack/db drizzle; PGlite-embedded by default, full Postgres by config). NOT Hermes.

@@ -24,16 +24,18 @@ The Mosaic Backlog is the backlog of record + dispatch engine, built on Mosaic's
- **NS-7** — Meta-loop (session-review + enhancer) continuously proposes small fleet-improvement PRs.
- **NS-8** — Single operator-flippable PAUSE kill-switch (fleet/run/PAUSED) honored before every dispatch and every merge.
- **NS-9** — Mosaic is a general-purpose multi-agent system: the user declares the SYSTEM TYPE to run (e.g. software delivery, personal assistant, research, business/operations) and the orchestrator provisions the matching persona roster and org structure from a cross-domain baseline persona library; the delivery/coding fleet is one profile among many.
- **NS-10** — An adoption is not complete until the mechanism it replaces is removed. Two live conventions for one concern is the defect, not a transition state. Measured 2026-08-20: brain-home adopted by 9 modules and not 10; MOSAIC_HOME honored in 4 places, each re-deriving it; backlog cards declared while TASKS.md files stayed authoritative. Every one was decided correctly and left half-applied.
## Success criteria
- **AC-NS-1** — The supervisor keeps a two-agent floor (1 orchestrator + >=1 enhancer) healthy across reboot.
- **AC-NS-2** — A goal added to this YAML is decomposed to cards and either merged or escalated, with no human in the loop.
- **AC-NS-3** — No PR merges with failure/error/no-status/timeout CI, and none bypass pr-merge.sh.
- **AC-NS-4** — TTL is enforced on claims; token caps remain advisory until a real meter exists.
- **AC-NS-5** — Flipping fleet/run/PAUSED halts dispatch and merges within one tick.
- **AC-NS-6** — A user can declare a system type and the fleet provisions the matching persona roster + topology from the baseline library, with no code change.
- **AC-NS-7** — A user-customized persona (edited or added via the orchestrator) survives mosaic update: baseline reseed never clobbers user overrides.
- **AC-NS-0** (tier 0) — The operator launches an agent on any configured harness with one command, observes its state and sends it work without attaching to a terminal multiplexer.
- **AC-NS-1** (tier 1) — The supervisor keeps a two-agent floor (1 orchestrator + >=1 enhancer) healthy across reboot.
- **AC-NS-2** (tier 1) — A goal added to this YAML is decomposed to cards and either merged or escalated, with no human in the loop.
- **AC-NS-3** (tier 1) — No PR merges with failure/error/no-status/timeout CI, and none bypass pr-merge.sh.

| I1 | One home resolver — a single function resolving MOSAIC_HOME with a sane default, adopted by every module. Today brain-home.ts is imported by 9 modules while 10 still use DEFAULT_MOSAIC_HOME, and MOSAIC_HOME is re-derived ad hoc in 4 places. NS-10 applies - finish the adoption and delete the second path | 0 | 1 | must-have | — |
| I2 | mosaic fleet ps sees the fleet that is actually running. Three measured blockers: the roster declares socket `mosaic-fleet` which does not exist, the 18 live sessions are on the default socket, and nothing writes a roster because seats are launched outside the CLI. Make the socket configurable and the roster written at launch, or make ps read tmux + seat dirs directly | 0 | 1 | must-have | I1 |
| I3 | Migrate fleet steering onto mosaic agent send --verify (exists, FLEET-OBS-005, spec FR-5) and retire tools/tmux/agent-send.sh, which forges the sender (D33) and returns an uninformative rc (D16, D34). FR-5 predates those defects by a month | 0 | 1 | must-have | I1 |
| I4 | mosaic fleet absorbs what launch-seat.sh does and launch-seat.sh is deprecated: compose the prompt file set, force the skill set, wire the style hook, fail closed on any unreadable input, export per-seat git identity, and register the seat in the roster. launch-seat.sh was a manual method; it is the reference implementation, not the destination | 0 | 1 | must-have | I1, I5 |
| I5 | Harness probe matrix — verify a working prompt-injection path for claude, codex, opencode and pi, and refuse any runtime whose path is unverified. AC-NS-0 clause 1 ("any configured harness") rests on this. The probe work in docs/plans/2026-08-19_launch-seat-multi-runtime.md (brain, untracked) transfers; its launch-seat.sh target does not | 0 | 1 | must-have | — |
| I6 | Finish the heartbeat responder (FLEET-OBS-002, the only Phase-2 task still in-progress; spec FR-2). Health must mean "answered a heartbeat", not "pane alive" — pane state measured two seats wrong on 2026-08-20 | 0 | 1 | must-have | — |
| I7 | Independent review and live-fleet dogfood of the Phase-2 verbs (FLEET-OBS-008), then land them (FLEET-OBS-009). Implementation is done and verification is not; "done" in a task file frozen five weeks is not evidence | 0 | 1 | must-have | I2, I3, I4, I6 |
| I8 | Neutralize misleading documentation — supersede headers on docs that state a stale status, a false blocker or a retired mechanism. Cheap, and it is tier 0 because a stale doc does not merely fail to help an agent, it actively misroutes one. Rebuilding the documentation is a separate and later job | 0 | 1 | must-have | — |
| I9 | Study t3code's agent-attach and multi-provider auth methods and record what transfers. Reference only — Mosaic implements its own within the stack, never adopts the code and never takes the dependency. Informs HOW I/J/K/L are built, not whether | 0 | 1 | should-have | — |
