# Parallel Batch Consolidated Summary — batch-task-2553-series-bf41e9b7608d

> Chair-only: this summary compresses to the chair's final decision points only (task-2553+17.md §4(11) / §6⑧).

- batch_label: `task-2553-series`
- batch_next_action: **CONTINUE_LOOP**
- tracks: 2 | goal_loop_plans: 1
- cross_track_contamination: NONE

## Per-track chair decision view
- `task-2553+16` → **DISPATCHED** (in-loop)
- `task-2553+17` → **RUNNING** (in-loop)

## Track3 goal-loop fold-in
- `task-2553+17` → status **PLANNED**

# task-2553+19 fold-in — Coordinator HIGH-4-fix loop (Track B)

> Chair-only consolidation (§8). No standalone report.

## Item 2 — Coordinator verdict: **HOLD_FOR_CHAIR**
- **CONVERGED (Codex cycle-3 RESOLVED, ANU↔Codex agree):** HIGH-1 (observed 4-tuple validation; self-fulfilling registry reconstruction removed) · HIGH-2 (single normalized `track_id` key) · HIGH-3 (`pending_blocks_chair_decision` applied; non-blocking pending no longer chair-blocks) · Codex-LOW (classify→batch_next_action end-to-end regression) · cycle-1 NEW-HIGH (persisted batch_next_action now reflects classified callbacks).
- **NOT CONVERGED — chair decision required:** HIGH-4 write-guard = ANU↔Codex **spec-divergence**, not a defect.
  - Impl satisfies authoritative §11 **9-R.2** exactly: `tracked→reject / untracked→allow`; coordinator's own untracked state/summary = idempotent overwrite-by-design (9-R.2 verbatim). Impl is *stricter* (refuses clobbering unrelated untracked files).
  - Codex cycle 2&3: demands newly-created-only (reject every pre-existing untracked path) → **contradicts 9-R.2's explicit idempotent-overwrite-by-design** and the chair-fixed `untracked→allow` regression contract.
  - ANU may not override an independent FAIL nor weaken authoritative 9-R.2 → escalate. Options A (affirm 9-R.2 as-written, recommended) / B (amend 9-R.2) in `task-2553+19.hold-for-chair.json`.
- Loop: 3/3 cycles (9-R.1 hard ceiling, zero infinite-retry). Codex FAIL×3; cycle-3 critical=0, unresolved_high=1 (same H4), no new findings.
- Regression: 23 prior PASS (zero regression) + 6 new = **29 passed**.

## Item 3 — Goal-loop generalization
- goal_loop_planner / fold-in unchanged (not in HIGH scope). Track3-MED (fold-in naming-heuristic → identifier-mismatch silent goal skip) = **non-blocking follow-up** (9-R.3).

## Item 4 — Invariants & scope
- Frozen anchor 10/10 byte-0 (pre==post). Live git invariant: HEAD `20456b5f…`, branch/ref unchanged (pre==post).
- No merge · no production code · no GitHub write (PR#128/#129/#102 untouched) · no Track A touch (task-2553+13.*/+1.*/+18.* untouched) · no credential/PAT · no scope creep.
- MED×2 + Track3-MED×1 = non-blocking follow-ups (9-R.3).
- Evidence: `memory/events/task-2553+19.result.json`, `task-2553+19.hold-for-chair.json`; Codex re-audit cycles 1–3 raw delivered.

## Item 5 — ANU Result Collector independent cross-verification (task-2553+19, recovery-only)

> Independent recovery/cross-check by ANU Result Collector. Read-only; no code modification. 4-tuple `task_id=task-2553+19` isolated; zero Track A (task-2553+13.*/+1.*/+18.*) citation/mixin.

- **(1) result.json internal consistency — PASS.** cycle1 FAIL/unresolved_high=1 (H1..H4+Codex-LOW RESOLVED, 1 NEW-HIGH raised) → cycle2 FAIL/unresolved_high=1 (NEW-HIGH RESOLVED, H4 re-flagged) → cycle3 FAIL/unresolved_high=1 (H4 only). `high_fixes` H1/H2/H3 `codex_status_cycle3=RESOLVED`, H4 `UNRESOLVED` (ANU-adjudicated RESOLVED per 9-R.2); before/after recorded for all 4. `verdict=HOLD_FOR_CHAIR`, `converged=false`, `converged_scope` all mutually consistent.
- **(2) Regression reproduced — PASS.** `pytest tests/regression/test_parallel_batch_coordinator_2553.py -q` → **29 passed in 0.19s**. Matches 23 prior (zero regression) + 6 new = 29; modified-file sha256 (parallel_batch_coordinator.py / batch_join_policy.py / test file) match `result.json` exactly.
- **(3) Frozen anchor — PASS, no HOLD.** `sha256sum -c frozen_anchor_baseline.sha256` → **10/10 OK** (byte-0, pre==post). No mismatch → HOLD not triggered.
- **(4) Live git invariant — PASS.** HEAD `20456b5f83fc039f2fd6f50f4b94095c29b41bfb`, branch/ref `task/task-2553p1-f1-clean-replacement` / `refs/heads/task/task-2553p1-f1-clean-replacement` — matches `result.json` live_invariant exactly (pre==post).
- **(5) Independent Codex re-audit (codex exec, read-only sandbox) — corroborated.** H1/H2/H3 RESOLVED, Codex-LOW RESOLVED. H4 RESOLVED for the stated envelope; sole divergence = whether pre-existing untracked deliverables may be re-written — explicitly characterized as **spec/definition-divergence, not a code defect**. This independently confirms ANU↔Codex **CONVERGED** scope (HIGH-1/2/3 · Codex-LOW · cycle-1 NEW-HIGH) and the **unconverged HIGH-4 = chair-decision** (spec-divergence).
- **Collector recovered verdict (unchanged):** `HOLD_FOR_CHAIR` — converged part RESOLVED & Codex-confirmed; HIGH-4 spec-divergence escalated (options A/B in `task-2553+19.hold-for-chair.json`). Scope clean: no merge / no production code / no GitHub write / no Track A touch / no credential / frozen-anchor 10/10. No citation or mixin contamination detected → no HOLD.
