### **D-1 / P-ACTIVATION + hygiene — committed `.npmrc` hard-pins `store-dir=/root/.local/share/pnpm/store`.** Correct for the CI container (runs as root), fatal for EVERY non-root local checkout: `EACCES` on `/root/.local/share/pnpm/store/v10/server/server.json`. A committed config that only works on one runtime is exactly the activation-skew class. Fix candidate: make store-dir env-overridable, not hardcoded. ### **D-3 / P-FLEET-001 — the seats running this mission are UNMANAGED.** `mos-remediation`, `rev-974`, `planner-opus`, `planner-sol` appear in NO roster (`~/.config/mosaic/fleet/roster.yaml`, `agents/`). Planners run on socket `default`; the roster declares `mosaic-fleet`. This is the exact "one roster-owned socket/host + quarantine unmanaged + stale GC" failure P-FLEET-001 indicts — observed on the remediation mission's own fleet. Prerequisite for INBOX identity-addressing. ### **D-2 / hygiene — husky `prepare` fails `EPERM` copying into root-owned `.husky/_/`.** Repo working tree has root-owned dirs (`.husky/`, repo root) under a non-root agent. Worked around with the intended `HUSKY=0` escape hatch (does NOT disable the existing pre-commit/pre-push hooks). ### **D-5 / P-QUEUE-001 + P-CONFORMANCE-001 — KEYSTONE: an inert gate that erased its own evidence.** Merged PR #868 (`b79336a8`) shipped a file that FAILS `pnpm format:check` ⇒ the CI format gate did not block. An unrelated later PR (#872) then reformatted that file via its own `lint-staged`, so `main` went green again and nobody learned the gate had failed to fire. Verified blob-level under the repo's own config. **Detection must be per-merge-commit against that commit's own tree** — a "is main green today" check reports all-clear on this exact defect. Binding on RM-02/RM-55. Full chain in `TASKS.md` §1a. NOT quiet-patched, by Mos's ruling: patching the symptom destroys the signal. ### **D-4 / P-LIFECYCLE + hygiene — a dispatched agent silently IGNORED an in-message context reset.** planner-sol was at 64.3%/372k; the brief asked it to reset first; it began work on dirty context anyway. Only an out-of-band `/new` driven by the orchestrator guaranteed clean state. Confirms the postmortem thesis: **instructions are not enforcement.** Reset must be a mechanical pre-dispatch step, not a request.
