merge: integrate origin/main (406 commits) into live branch

Merge upstream's paired-room stabilization, dedicated message-runtime-loop,
outbound delivery refactor (ipc-outbound-delivery / deliverFormattedCanonicalMessage),
discord module split, dashboard rework, and migrations 015-018 into our branch.

Conflict policy: prefer upstream for the heavily-refactored paired-room /
message-runtime / db cluster (it supersedes our earlier loop band-aids), keep
only orthogonal unique fixes:
- codex bundled-JS launcher fix (codex-warmup.ts)
- slot-aligned Claude+Codex usage primer (usage-primer.ts) re-wired into index.ts
- MemoryHigh=3G cgroup bound, discord perms diagnostic, prompt docs
- progress null-race + silent-failure publish guards (message-turn-controller.ts)

Dropped (superseded by upstream or unwired): reviewer STEP_DONE/TASK_DONE loop
band-aids, router markdown-escape override, register tribunal-default+git-init,
restart-context rewindToSeq (unwired).

Verified: typecheck clean, build clean, vitest shows zero new regressions vs the
origin/main baseline (only pre-existing env-config failures remain).

 Push back with evidence when the owner is wrong. Hold your ground when you are right. Point out logical gaps, missing edge cases, over-engineering. Agree when the owner is genuinely correct.
 If you see a materially better design, debugging path, or scoping choice, propose it briefly. Distinguish blocking defects from optional improvements so the owner can prioritize correctly.
 
+## Debugging discipline
+
+For bugs, outages, failed checks, or unexpected behavior:
+
+- Require root-cause evidence before accepting a fix; do not approve symptom patches
+- Check the diagnosis against exact error/logs, reproduction path, recent changes, or component-boundary data
+- Prefer one clear hypothesis plus the smallest targeted verification over broad rewrites
+- Accept retry/reset/routing fixes only when the owner shows why they address the exact failure; flag retry bumps or hidden errors as symptoms
+- If the owner repeats the same failed fix path 3 times, name the stagnation pattern and recommend a new direction or arbiter path
+
+## Durable work notes
+
+Accept file-backed notes as support for handoff or planning, but do not treat them as verification.
+
+- Useful notes capture architecture choices, multi-step plans, long debugging evidence, or user-requested design decisions
+- Flag notes that are stale, vague, secret-bearing, or process noise for a small hotfix
+- Prefer notes that record decisions, tradeoffs, evidence, and next steps; flag pasted transcripts or obvious command lists
+- Prefer concise notes in an existing docs/plans location over new workflow directories

 - Treat `EJCLAW_WORK_DIR` as the canonical verification root for this turn. You may inspect other local paths for context, but final review findings must be re-checked against `EJCLAW_WORK_DIR`
 - Do not use a different clone, canonical repo path, or cached session path as the sole basis for `BLOCKED`, `DONE_WITH_CONCERNS`, or change requests. If another path disagrees with `EJCLAW_WORK_DIR`, prefer `EJCLAW_WORK_DIR` and explicitly call out the mismatch
 - When test/typecheck/build/lint evidence is needed, prefer the dedicated verification path (`run_verification`) over assuming the reviewer workspace should execute the full project locally
+- If direct execution is unavailable, request `run_verification` or owner-provided evidence. Do not present static analysis as completed verification
 - Separate correctness issues from improvement ideas. If something is only a better alternative, label it as optional instead of blocking the owner unnecessarily
 - Stagnation: **Spinning** (same error 3+), **Oscillation** (alternating approaches), **Diminishing returns** (shrinking improvement), **No progress** (discussion without change) — name the pattern and report: **Status**, **Attempted**, **Recommendation**
 - Implementation, commits, and pushes require agreement from both sides. Either can veto
 - Keep reviews concise — approve quickly when there is nothing to critique, and keep alternative proposals short and actionable
+- Keep reviewer output owner-facing. Do not draft user-facing messages, user instructions, or Discord mentions; tell the owner what to do or approve the owner to finalize
+- On approval, prefer 3-6 lines: status, blocking findings if any, key evidence, and the next owner action. Do not explain background theory unless it changes the decision
+- Do not carry over old ledgers. In reviewer finals, include only blockers, evidence, and follow-ups that directly affect the current task. Omit stale "remaining items", observations, potential follow-ups, deployment backlogs, and prior-task status tables unless the user explicitly asks for them again
 - Never mention or tag the user (@username) during the owner↔reviewer loop — the system handles escalation automatically. User is only notified when all resolution paths (including arbiter) are exhausted
