{"type":"assistant_message","payload":{"text":"I read this as a final release-gate decision - I audited the sealed bytes and control flow without invoking the live path and am returning the evidence-backed verdict.\n\n# FAIL\n\nCandidate `a88071d999155e52433c00891b2886f8867fe80ae749936fa1b6688eec123cf8` is internally immutable and correctly bound, but V14 r10 is not release-safe because its executable preseal closure is mutable, one sealed recovery input is not verified, and pre-snapshot interruption recovery is incomplete.\n\n## Gate results\n\n| Gate | Result | Exact evidence |\n|---|---|---|\n| Candidate immutability | PASS | Candidate has exactly 324 expected files. All 322 inventory rows matched SHA-256, had no write bits, and had link count 1. Recomputed derivation equals the claimed candidate digest. Manifest SHA-256 is `e6605df2510f46af8267a1fae250aa7762b12b9e4d198a19299610cb7d621832`. |\n| Launcher reachability | PASS structurally, FAIL integrity | Launcher hash `dfffb7b8...` matches worktree and preseal. It enters r10 bootstrap, which execs the worker, which imports `execute_authorized`. However, mutable unmanifested bytecode can be imported after verification. |\n| One-use authority | FAIL end-to-end | `GlobalLedger.reserve()` correctly uses `O_EXCL`, and the live ledger/execution/successor paths are currently absent. But process death before snapshot creation leaves states the recovery algorithm cannot close. |\n| Registry binding | PASS | Current registry SHA-256 is exactly `bd61ed95f80737ba8013db262fd0242a600e540f43f6627f5b9708a599660b29`; shape is two customers with only `pilot_20260820_01` enabled. Package shape digest recomputes to bound value `bb911adc...`. |\n| Recovery boundaries | FAIL | `PREPARING` and no-phase interruption windows are unrecoverable; rehearsal rollback evidence is left in `PREPARING`, not `ROLLED_BACK`. |\n| Controller/launcher target agreement | PASS | Launcher, bootstrap, worker, controller `SEALED_TARGET`, transaction plan, target binding, candidate, package, and successor runtime all resolve to r10/a88071d9. Controller derivation recomputes to `c4e0d802...`. |\n| Rehearsal identity | FAIL as release evidence | Candidate/package/wheels match, but rehearsal calls `execute_disposable` with `DisposableService`, not launcher -> bootstrap -> `execute_authorized`; all 12 rollback cases report PASS while their durable phases are `PREPARING`. |\n\n## Release blockers\n\n### 1. The verified controller closure contains mutable, unmanifested executable bytecode\n\nPreseal inventory verification found all 326 declared rows correct, but the directory contains 343 regular files versus 327 expected including the self-excluded manifest: **16 undeclared `.pyc` files**.\n\nExamples:\n\n- `controller-source/scripts/__pycache__/nutricoach_v150_sealed_controller.cpython-312.pyc`\n- `controller-source/scripts/__pycache__/nutricoach_v150_detached_bootstrap.cpython-312.pyc`\n- `controller-source/scripts/__pycache__/nutricoach_v150_sealed_authority.cpython-312.pyc`\n\nThey are mode `0644`; their parent directories are mode `0775`. None appear in either package or controller-source manifests.\n\nThe sealed-controller bytecode header is timestamp-based:\n\n- flags: `00000000`\n- embedded source timestamp: `0x6a919e0a` = source mtime `1787928074`\n- embedded source size: `0x2516` = `9494`\n\nThose values exactly match `nutricoach_v150_sealed_controller.py`, making this bytecode import-eligible. Bootstrap verifies listed source files at `nutricoach_v150_detached_bootstrap.py:145-147`, then the worker imports the controller at `nutricoach_v150_controller_worker.py:11`. The mutable bytecode itself is never hashed.\n\n### 2. The protected inventory is writable and its sealed digest is unused\n\n`preflight-v14-live-representative-r10/snapshot-before.json` is mode `0600`, owner `cube`, and resides under the migration tree mounted writable by launcher lines 42-44.\n\nIts current digest does match the declared value:\n\n`d2c084be0865f8e9844452a7b683f97800e31af9bc7e1a113241109a283aada5`\n\nBut `protected_inventory_sha256` has **zero source-code references**. The live host loads only its path (`nutricoach_v150_concrete_host.py:156-166`), and `protected_paths()` dynamically trusts its `profiles.stable` rows (`nutricoach_v150_host_operations.py:42-65`). The preseal verifier checks the permission-package hash but never hashes this inventory (`verify_nutricoach_v150_preseal_v14.py:198-217`).\n\nConsequently, the catalog of 86,756 protected `dualcoachtest` stable paths can change without bootstrap or preseal denial.\n\n### 3. Recovery does not cover the pre-snapshot interruption window\n\nController ordering is:\n\n1. Write recovery manifest: `sealed_controller.py:169`\n2. Write phase `PREPARING`: line 171\n3. Reserve authority: line 174\n4. Create snapshot: line 182\n\nRecovery loads a snapshot for every pending phase except `STOPPING` and `RESERVED` (`sealed_controller.py:209-220`).\n\nTherefore:\n\n- Death after recovery-manifest creation but before phase creation leaves an execution root with no recoverable phase; subsequent preseal verification rejects `authority_touched`.\n- Death in `PREPARING`, including during reservation, calls `load_snapshot()` even though no snapshot exists yet.\n\nThe rehearsal artifacts expose the same state inconsistency:\n\n- All 12 rollback cases are reported `PASS`.\n- Every durable rollback phase is `PREPARING`.\n- Every ledger is `CONSUMED:FAILED`.\n- `rollback-stop` has no snapshot at all.\n- `PhaseJournal.recovery_required()` explicitly treats `PREPARING` as pending.\n\nReport SHA-256: `c698d2a19904d776e9bfbe11a835cd4f68bf42a16f7e1207d5b022aa4eff8404`.\n\n## Architecture decision\n\nTwo viable corrections:\n\n1. **Harden the existing design**\n   - Reject unmanifested files, remove bytecode, run with `-B`/`PYTHONDONTWRITEBYTECODE`, and make preseal directories read-only.\n   - Verify every external sealed digest before use.\n   - Add explicit pre-snapshot recovery states and terminal-state rehearsal assertions.\n   - Lowest migration cost and preserves current test seams.\n\n2. **Package the controller as one content-addressed executable artifact**\n   - Launcher verifies and runs a single read-only zipapp/wheel-like closure.\n   - Smaller import attack surface, but higher packaging migration cost and tighter build/debug coupling.\n\n**Recommendation: option 1.** It is the smallest architecture that closes the actual failures; a new packaging framework is not justified.\n\nNo authorization, live execution, network, Telegram, provider, customer, service, commit, or push action was run. No audited file was modified."}}
