mos-dt-0andClaude Opus 5 2a9360407b docs(remediation): bank D-53 — a sender label that was wrong for hours while looking exactly right
agent-send.sh derived the sender label from the DESTINATION socket flag, so cross-socket messages were
stamped with an arbitrary session from the socket the sender was not attached to. One lead's messages
arrived for hours stamped as the recipient. Fixed on main; source now comes from the caller's own $TMUX.

The label was false and plausible simultaneously, which is the only dangerous kind — a garbled label
gets questioned, a label naming a real seat on a real socket does not. Same family as D-33's summary
that resembles an enumeration and D-48's boundary statement that reads as rigorous.

The transferable part is the fix's design choice: it now reports "?" rather than borrowing a plausible
name. That is the same discipline as NOT-MEASURED, adopted the same day on the credential thread —
absent must be rendered absent, not as a pass and not as a fail. An unknown rendered as a plausible
value is consumed as fact; an unknown rendered as unknown is consumed as a question. Two subsystems,
one day, same conclusion, independently.

Audited my ledger on receipt: clean, zero mis-attributed sources in TASKS.md or BOARD.md. The reason is
practice rather than luck — rulings were recorded from the message BODY, which carried its own
[mos-claude -> mos-remediation] header, not from the transport envelope. Where a message
self-identifies, the body is the claim and the envelope is metadata, and the envelope was the broken
part.

Routing defect now doctrine: the USC message was addressed to "orchestrator", a ROLE that exists on
each estate, and agent-send resolves a session NAME. Binding rule: address seats, not roles, and
estate-qualify any name that exists on both estates. The cost was bounded only because the recipient
declined to act on another estate's delivery while still checking whether any line of it constrained
its own — declining to act but silently letting a stale cross-estate constraint ride would have been
the actual failure.

# mos-remediation — LIVE BOARD (keep < 8 KB)
**Phase:** EXECUTING — RM-03 at owner-merge; RM-61 **MERGED**; **RM-02 keystone is the front**.
**Updated:** 2026-08-01 — seam crossed; successor seat resumed, attested from the files, and is driving.
⚠ That was a **MANUAL pane respawn** (prior seat ~803k tokens): it validates the checkpoint+rehydration
**design**, NOT a lifecycle **mechanism** — P-LIFECYCLE rotation does not exist yet (**D-41 / RM-62**).
## Head
- Charter + 15 decisions + 4-build plan: `MISSION.md`. Backlog + all findings: `TASKS.md`.
- Planning DONE (58 tasks, P0P5). **DECISION-1/2/3 all RULED by Mos 2026-07-31** (`TASKS.md` §5) —
nothing is waiting on a decision. D-2's availability _target_ is Jason-pending and non-blocking.
- **Executing, not planning.** RM-01 is MERGED; three lanes are live (see In-flight).
- Orchestrator seat `mos-remediation` LIVE, owns the mission, resumed across the rotation seam
2026-08-01 and re-attested to Mos from the files. Residency attestation: PASS.
## In-flight
| Task | Owner | State |
| ------------------- | --------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| RM-01 checkout | — | **MERGED** `f58b3699` (#1027) |
| RM-03 queue guard | Jason (re-sync) | ✅ **MERGED** `58b971ab` (#1032), #1019 closed. ⚠ **NOT DELIVERED**: installed guard still the broken one (291 lines / 0 `ASSERTED_NOT_READY` vs main 482 / 5). Re-sync via `mosaic upgrade`, then **prove it blocks a KNOWN-RED pipeline****D-51** |
| RM-02 registry ★key | rev-974 | **RE-REVIEW @ `e910a45a`** — (d)-strict history REMOVED + blocker 2 NARROWED (D-52) + blocker 3 + renderer. Overclaim control **fires at exit 84**, verified by orchestrator. CI 2201 **10/10**. ACs @ `dde38717` |
| RM-61 CI exemption | — | ✅ **MERGED** `f4fd5967` (#1033). #1034 closed; **#1000 stays OPEN** (retirement trigger). Exemption is on `main` |
| RM-59 / RM-60 | Jason (infra) | tracked deps; RM-60 option **B** |
| #1023 queue attempt | Jason | SUPERSEDED-PENDING-JASON — live REQUEST_CHANGES, do **not** merge |
### For the incoming orchestrator — read this before acting
1. **Lane state lives in the In-flight table above — this item does NOT restate it.** It went stale
three times in one session by duplicating that table (D-26's class). Read the table. ⚠ **And
re-derive any board claim from the provider before load-bearing use (D-43)** — the board is
sole-written and has no independent verifier.
2. **`docs/remediation/TASKS.md` is authoritative**, not the newest voice in a chat. It holds 54 findings
(D-1…D-6 in `BOARD-LEDGER.md`, D-7…D-53 + D-38c in TASKS.md), every ruling with its rationale, and the
requirements each finding placed on RM-02/RM-34/RM-50/RM-55.
3. **`MISSION.md` carries the first-class principles** — read them there, they are not listed here.
Two added 2026-08-01: **the anchor must live outside the audited party's authority** (D-19/D-25/D-45,
third arrival) and **no universally-quantified check may pass over an empty set** (D-44/D-46).
4. **Seat identity:** `export MOSAIC_GIT_IDENTITY=<seat>` is stripped by a context reset (**D-34**) —
every dispatch/rehydration brief must re-export it, or the seat cannot use its credentials.
5. **Scan CI from `-f json`, never default text** — text mode omits `clone` (**D-33**). State counts.
6. **The queue guard is zero-information until RM-03 merges** (**D-23**) — never cite its green.
7. **The bounded CI re-roll used on RM-02 was a one-time stopgap, NOT policy.** A per-PR free re-roll is
D-21 normalisation. Do not repeat it; RM-61 is the fix.
## Delivery gates — REFERENCE, do not restate
Canonical: `~/.config/mosaic/fleet/roles.local/merge-gate.md` (verdict authority) +
`~/.config/mosaic/fleet/roles/validator.md`. Order and the freeze/zero-information rules: `MISSION.md`
and `KICKSTART.md`. **Read them there** (why: **D-26**, in `BOARD-LEDGER.md`).
## Fleet seats
Roster rolled verbatim to [`BOARD-LEDGER.md`](./BOARD-LEDGER.md); live truth is `mosaic fleet ps`.
## Gate status
- Freeze: LIFTED for this workstream only.
- Git identity: orchestrator runs `MOSAIC_GIT_IDENTITY=mos-dt-0` INTERIM. Mos ruled gate-16 HOLDS (author≠reviewer is what
gate-16 protects; rev-974 reviews, mos-dt-0 never self-reviews). Dedicated identity TRACKED, Mos provisions.
- Capability + seat identity (**D-11b / D-11a**, incl. the false-NEGATIVE twin): authoritative in
`TASKS.md`. Short form — **assert the DIFFERENTIAL as that seat** (authenticated `push:true` vs
unauthenticated `push:false`); a single endpoint can be true for anyone or 403 for an unrelated
scope. Full text rolled to [`BOARD-LEDGER.md`](./BOARD-LEDGER.md).
-**LIVE HAZARD (D-37) — one shared `.git/config` re-identifies EVERY worktree at once.** Every seat,
including `rev-974`'s review worktree, currently authors as **`coder-mos1`**; `MOSAIC_GIT_IDENTITY`
does **not** override it. **STANDING ORDER: commit with explicit
`git -c user.name=<seat> -c user.email=<seat>@…`, and NOBODY rewrites the shared config mid-flight.**
Real fix authorised, Mos owns it, sequenced at a quiet seam. **#1024 implicated.** Detail: D-37.
- Standing worker-brief doctrine (mandatory in EVERY brief): re-export `MOSAIC_GIT_IDENTITY` (**D-34**);
commit early/WIP (**D-31**); don't weaken a RED test to pass; if a check is unrunnable SAY SO, never
substitute; `agent-send -f` never `-m`; artifacts off shared `/tmp`; scan CI from `-f json` (**D-33**);
**relay observations into an open review, NEVER your own conclusion on an open check (D-39)**; the
**author never adjudicates their own PR's blocker status** — surface evidence, prepare the fix, hold.
- Remote control: native `/remote-control` NOT wired in this runtime. Path is **Mos-relay**
(Jason ↔ mos-claude via Discord ↔ mos-remediation via agent-send). Not a blocker.
## Decisions log — full record in [`TASKS.md`](./TASKS.md)
All 54 findings (D-1…D-6 in `BOARD-LEDGER.md`, D-7…D-53 + D-38c in `TASKS.md`) and every ruling with
its rationale live there. **Not duplicated here.** The history of _why_ this board must not restate —
six stale copies across two seams — is rolled verbatim into [`BOARD-LEDGER.md`](./BOARD-LEDGER.md).
