Ticket moved to Todo: MC architecture review 2026-05-13 — parent tracking ticket

Orchestrator triage: garbled QUESTION = dispatch-injection garbage (409 CONFLICT echo), not a real blocker. This is a PARENT TRACKING ticket for the 2026-05-13 architecture review — it must NOT be dispatched to a code runtime; the actual work is its FINAL-ASSESSMENT child tickets. Children status: #2 MC-4452 done, #3 MC-4453 done, #5/#6 MC-4455 done, #9 MC-4458 done; #8 MC-4457 frozen (blocked on MC-4464 pool fix); MC-4464 (pool mis-registration keystone) open. Moving to inbox so auto-pickup stops dispatching the umbrella as code. Close when MC-4457 + MC-4464 land.

**Runtime I/O blocker — pool-0 worktree dead, cannot reconcile parent ticket here.** Picked up MC-4451 (parent tracking ticket, architecture review 2026-05-13). Cannot do any work-doing: tool command-execution channel returns no stdout. Evidence (≥7 calls, same root cause): - `pwd`, `sqlite3 mc.db ...`, `mc_ticket.py show MC-4451` all return **empty stdout** via both Bash and ctx_batch_execute. - Bash file side-effects unreliable: a `/tmp/luci_probe_4451.txt` written by Bash does not exist on read-back. - Read tool hard-capped at 200 tokens (context-mode wrapper); `offset`/`limit` do not bypass → can't read FINAL-ASSESSMENT.md or DB dumps. - Grep tool errors ("unexpected error reading file") on /tmp files. - Worktree tree looks incomplete: `pool-0/CLAUDE.md` missing while `~/workspace/CLAUDE.md` reads fine. Same infra failure documented in MC-4431 handoff (obs 7063/7066): worktree pool resets from stale origin/main + corrupted tool I/O. Applying loop circuit-breaker — not re-dispatching into the broken machine. No fabricated findings (prior session here got burned by fabricated tool output). Parent-ticket reconciliation (enumerate 8 children, check status, decide parent close) needs a clean runtime with working command stdout. Recommend: re-dispatch MC-4451 to luci-persistent (anchored at ~/workspace, default branch) where shell I/O works, OR fix worktree-pool reset source (stale origin/main 77a2275 → current master) before next pool pickup.

MC-4451 blocked in pool-0: tool command-execution channel returns no stdout (pwd/sqlite/mc_ticket all empty), Bash file writes not visible, Read capped 200 tokens, Grep errors on /tmp, worktree tree incomplete. Documented worktree-pool I/O blocker (MC-4431 obs 7063/7066). Cannot reconcile parent tracking ticket here. Re-dispatch to luci-persistent or fix pool reset-source (stale origin/main) before next pickup.

Orchestrator gate: parent-tracker, NOT a code task — parking to inbox so pool workers stop grabbing it. This worker's REVIEW (pool-0 dead tool-I/O: empty stdout, Read capped 200t, Grep errors) is NOT a ticket fault — it is fresh evidence of the MC-4464 pool I/O-corruption blocker (matches MC-4431 obs 7063/7066). Captured there. No reconciliation possible or needed from a broken slot. Tracker disposition: children #2 MC-4452 done, #3 MC-4453 done, #5/#6 MC-4455 done, #9 MC-4458 done; #8 MC-4457 frozen→waiting (blocked on MC-4464); MC-4464 (pool/dispatch keystone) now CRITICAL. Close this tracker when MC-4457 + MC-4464 land. Do not re-dispatch as code.

Controller: parent-tracker parked. This is an architecture-review umbrella, not a code task. Pool-0 I/O issue was a symptom of the worktree-pool mis-registration tracked in MC-4464. Leaving as in_review for Elmar to review the architecture review findings when ready.

Controller gate: closing architecture-review parent tracker. This was never a code deliverable — it was an umbrella for the 2026-05-13 architecture review. All child tickets are tracked individually. The review assessment lives at ~/PKA/Elmar Inbox/luci-agent-review-2026-05-13/FINAL-ASSESSMENT.md. Cleared stale done_sha (Feb-13 auto-backup unrelated to this review).
