Reviewer finding: `.omo/evidence/task26/task26-post-lifecycle-cleanup-v3-4a6c7ee5-st_01a00e50/cleanup_controller.py:44` uses a single unchecked `os.write(fd, raw)` before fsync/rename. Existing v3, its seal 84d937..., archive root 9f5d72..., and cleanup receipts are immutable and must not be edited or re-executed; current archive independently verified byte-exact, so no cleanup replay. Under a new `.omo/evidence/task26/task26-post-lifecycle-cleanup-v4-...` root via apply_patch, copy/derive the controller and replace atomic payload writes with a small robust write-all helper: loop on memoryview until every byte is written, retry InterruptedError, reject zero/negative/impossible counts, close/unlink temp and never rename on failure, preserve O_NOFOLLOW/exclusive mode0600/fsync file+directory/atomic rename semantics. Use helper for every archive/receipt atomic write. Add deterministic tests monkeypatching `os.write` for repeated partial writes, InterruptedError then success, zero write, raised OSError, and ensure exact bytes, no truncated rename, no leftover temp, no mutation command after archive write failure. Include regression proving v3 would fail the partial-write simulation and v4 passes. Bind candidate 4a6c7ee5..., lifecycle seal 50e7556..., v3 seal 84d937..., existing archive root, current clean poststate. Run tests, Ruff, compile/LSP, dry-run/verify/independent verify against current clean state only; do not execute mutations or require active customer. Seal/inventory/root independently. No product source/config/service/Git/plan/todo/Boulder/ledger changes. Return v4 root/controller hash/tests/verifiers/inventory/seal and exact evidence that addresses the finding.\n\n<Category_Context name=\"deep\">\nYou are operating in DEEP mode. This is the category reserved for goal-oriented autonomous work on hairy problems that reward thorough exploration and comprehensive solutions.\n\nThe orchestrator chose this category because the task benefits from depth over speed. You should feel empowered to spend the time needed: five to fifteen minutes of silent exploration before the first edit is normal and correct. Rushing to implementation on a deep task is a failure mode, not a feature.\n\n# How deep mode adjusts the base behavior\n\n**Exploration budget: generous.** Read the files you need, trace dependencies both directions, fire 2-5 explore/librarian sub-agents in parallel for broader questions. Build a complete mental model before the first `apply_patch`. Exploration here is an investment, not overhead.\n\n**Goal, not plan.** You receive a GOAL describing the desired outcome. You figure out HOW to achieve it. The orchestrator deliberately did not hand you a step-by-step plan; producing one and asking for approval is not what was asked. Execute.\n\n**Atomic task treatment.** When the goal contains numbered steps or phases, treat them as sub-steps of ONE task and execute them all in this turn. Splitting them across turns is wrong unless they reveal an architectural blocker that requires the user's input. If the \"steps\" turn out to be genuinely independent tasks that should have been separate delegations, flag that in your final message and refuse the ones beyond scope.\n\n**Root cause bias.** Prefer root-cause fixes over symptom fixes. A null check around `foo()` is a symptom fix; fixing whatever causes `foo()` to return unexpected values is the root fix. Trace at least two levels up before settling on an answer. In deep mode, you have permission (and the expectation) to do the deeper fix.\n\n**Ambition scaled to context.** For brand-new greenfield work, be ambitious. Choose strong defaults, avoid AI-slop aesthetics, produce something you would be proud to hand to another senior engineer. For changes in an existing codebase, be surgical and respect the existing patterns; depth does not mean invasiveness.\n\n**Completion bar: full delivery.** \"Simplified version\", \"proof of concept\", and \"you can extend this later\" are not acceptable deliveries for a deep task. The orchestrator routed here specifically for a complete solution. If you hit a genuine blocker (missing secret, design decision only the user can make, three materially different attempts all failed), document it and return; otherwise, finish the task.\n\n**Status cadence: sparse.** The user is not on the other side of this conversation; the orchestrator is, and they will synthesize your progress. Send commentary only at meaningful phase transitions (starting exploration, starting implementation, starting verification, hitting a genuine blocker). Do not narrate every tool call; silence during focused work is expected.\n</Category_Context>"},"host_pid":1761519,"final_response":"I read this as completed implementation and evidence delivery - the sealed v4 successor is ready and independently verified.\n\nRoot:\n`.omo/evidence/task26/task26-post-lifecycle-cleanup-v4-4a6c7ee5-st_01a00e68`\n\nKey hashes:\n- Controller: `7750425a92b611fb0ac7155ca3007b3398900de1ae0be2a39eb03071333a8cd0`\n- Tests: `7a469b5d8eb8383fb13d1b4165e1053aec0115a5b39c666965252e0e46723393`\n- Independent verifier: `e2ef688b72d0bb1548fdb17b1e9ac1ae4cb9a005077282a72ee8c3b9ba4e200e`\n- Seal verifier: `2c7499ddca2d977dc4fd84c1659040d4873754d4d24ef14fe71bda533c6a1fd2`\n- Inventory: `406b4eb3a18c003c3b14d59af56917ec2e391715a50ce13fdd06aa0416b74ee5`\n- Evidence root: `1fd017728ee586e2955b465a9ff7cf56437404bb4074714a7874e781228f7dd4`\n- Seal: `188e9e630b53e9329ae185fc8c007aecb7988c16d174d325d68e8e004edb38e9`\n\nFinding closure:\n- `write_all()` loops over a `memoryview` until complete.\n- Retries `InterruptedError`.\n- Rejects zero, negative, non-integer, boolean, and over-length write counts.\n- Write/fsync/close failures unlink the temporary file before publication.\n- Atomic replacement, file and directory fsync, exclusive mode-0600 temporary creation, and no-follow behavior are preserved.\n- All archive and receipt writes remain routed through `atomic()` and therefore `write_all()`.\n\nVerification:\n- Pytest: `12 passed`\n- Ruff: PASS\n- Compile: PASS\n- LSP: 0 errors\n- Dry-run: PASS, `mutations: 0`, `cleanup_replayed: false`\n- Controller verification: PASS\n- Independent verification: PASS, 84 checks\n- Seal verification: PASS, 19 evidence entries and 172 archive entries\n- Regression demonstrates v3 produced `abc` from a simulated partial write of `abcdefgh`; v4 produced exact `abcdefgh`.\n- Archive-write failure test proves no rename, no temporary residue, and no mutation command.\n\nPreserved bindings:\n- Candidate: `4a6c7ee54cf9526a30de8bb576c1d71b411938beba33a04914738f6e1b6ed1cb`\n- Lifecycle seal: `50e7556e58a876d8136fbfb2023ede8bcb46ac816d97d4b85e1d0559f463d008`\n- Immutable v3 seal: `84d937ef67c1517bfdbca4cabce9fb4bfbe39aa1165458bb3aedd14decc4bff0`\n- Existing archive root: `9f5d72840b4cc1fcb57720a61ebc53529fa00202d9201615e4ebdbb3e047a635`\n\nNo cleanup execution or live mutation occurred.
