I read this as authoritative r71b maintenance packaging under a frozen-worktree, fail-closed protocol - I’ll first prove the preconditions without writing, then package, seal, verify, and emit the DoneClaim only if every invariant passes.


The fail-closed prewrite gate found five source/test hash mismatches against the authenticated runtime receipt; per the explicit stop rule, I’m not creating, deleting, or reusing any root and will identify the exact conflicting anchors for the blocker.


I read this as authoritative r71b packaging - the mandatory prewrite hash gate failed, so I stopped without mutation.

**Exact blocker: `FROZEN_SOURCE_HASH_MISMATCH`**

Five files differ from authenticated `task-10-r71b-maintenance-runtime.json`:

- `cron/scheduler.py`: expected `07fddef7...f461f`, observed `eb4ea4de...647b`
- `nutrition_weekly_maintenance_contract.py`: expected `f7738471...a619`, observed `ab3908f...889b`
- `nutrition_weekly_maintenance_store.py`: expected `1affe722...fa`, observed `cb4c436d...3964`
- `nutrition_weekly_maintenance_adversarial_support.py`: expected `8cef1f9a...9e25`, observed `4d3596c2...d6c8`
- `nutrition_weekly_maintenance_support.py`: expected `810ab476...df5d`, observed `33d1659d...921f`

Prewrite checks that passed:

- KST: `2026-09-01T20:38:23+09:00`, before expiry.
- All authoritative r71b candidate/preseal/preflight/rehearsal/build/input/action/runtime/observer roots absent.
- All four old-r71 tombstone trees exactly matched expected digests and inventories.

No files or roots were created, edited, deleted, chmodded, or reused. No build, service, profile, network, provider, customer, Git, authorization, execution, or observer action occurred. The requested evidence file was not written because the protocol forbids every write after a mismatch.


I read this as an authorized retry using the consolidated 74-file freeze as the sole source authority - I’ll rerun every fail-closed prewrite check, then create and verify the one-use authoritative package only if they all pass.


The consolidated freeze, 74-file hash stream, clock, root absence, and tombstone gates all pass. I’m starting the one-use clean A/B wheel build into fresh authoritative build/input roots.


The first and only candidate seal created the immutable candidate, but its immediate verifier failed because the requested external receipts root was not the candidate’s canonical `receipts/` path. I will not reseal or mutate the candidate; I’m checking whether the seal itself is incomplete and therefore a terminal blocker under the once-only rule.


I read this as the authorized one-use packaging retry - it stopped fail-closed during the sole candidate seal.

**Exact blocker: `AUTHORITATIVE_CANDIDATE_DIGEST_MISMATCH`**

- Expected candidate: `01dcf83...559cf`
- Sealed candidate: `9d3d94b231b82e31a6caf654ae3a5b0001009c9ba770f88ffb6209202b86d9fb`
- Cause: the authority verification receipt root was empty when sealing, so the immutable candidate omitted `receipts/authority-verification.json`.
- Canonical verifier rejected it for the missing receipt.

The candidate root is now occupied and immutable. Under the once-only/no-delete/no-reuse rule, I did not modify, delete, or reseal it. Preseal, permission, rehearsal, action, live, and observer roots remain absent. No source, live profile/service, network, provider, customer, Git, authorization, or execution action occurred.

No DoneClaim or authoritative-package evidence was written because all gates did not pass.


I read this as a final one-use R2 seal into a fresh candidate namespace while preserving attempt 1 as a tombstone - I’ll locate and authenticate the new consolidated evidence, run every prewrite gate, then seal and verify only if all exact anchors pass.


All R2 prewrite gates pass: the latest adversarial receipt, 134-file freeze stream, nonempty authority receipt, failed-attempt tombstone, old tombstones, clock, and every R2/action/live root are exact. I’m starting fresh R2 A/B builds and will preload the sole receipt before the one permitted candidate seal.


I read this as the final R2 authoritative seal - it stopped fail-closed during the sole candidate seal.

**Exact blocker: `R2_SUCCESSOR_OVERLAY_STALE`**

- Expected candidate: `2a85524e...843f6`
- Produced candidate: `2025ec891a3d93379370fb8e4ee41c922cf37b6d638ab67de3e3bfbcfe043e7c`
- Canonical verifier rejection:
  `successor overlay mismatch: scripts/nutricoach_v150_r71b_preparation.py`

The failed-attempt-1 overlay was stale relative to freeze134’s YAML-bound source. The R2 candidate root is now occupied and immutable; under the once-only/no-delete/no-reuse rule, I did not alter or reseal it.

Preseal, permission, rehearsal, authorization, execution, runtime, profile-hold, observer, and live roots remain absent. No source/live/network/provider/customer/Git action occurred. No DoneClaim or authoritative-package evidence was written because all gates did not pass.
