{"type":"assistant_message","payload":{"text":"I read this as a read-only root-cause audit - the evidence supports a real observer-arm failure, but not deterministic inotify exhaustion.\n\n## Diagnosis\n\nThe failing gate was:\n\n`tests/gateway/test_source_golden_path_verifier.py::test_driver_bundle_passes_native_verifier_with_terminal_inventory`\n\nIt launched:\n\n```text\npython scripts/source_golden_path.py \\\n  --source /home/cube/.cache/task26-strict-successor-1786976146/src-p \\\n  --evidence-root /tmp/pytest-of-cube/pytest-387/test_driver_bundle_passes_nati0/bundle\n```\n\nThe exact failing operation was effectively:\n\n```c\nfd = inotify_init1(O_CLOEXEC | O_NONBLOCK);  // succeeded\n\ninotify_add_watch(\n    fd,\n    \"/tmp/pytest-of-cube/pytest-387/test_driver_bundle_passes_nati0/\"\n    \"bundle/data/onboarding/telegram-customer-bootstrap-v1\",\n    392  // IN_CLOSE_WRITE | IN_MOVED_TO | IN_CREATE\n);\n```\n\nThis follows directly from:\n\n- `source_golden_path.py:374-375`: one `watched_paths` entry, `ledger.json`.\n- `gateway/commit_observer.py:73-80`: watches `path.parent`.\n- The failure being `inotify_watch_failed`, rather than `inotify_init_failed`.\n\n### Cardinality and capacity\n\n- Requested files: **1**\n- Unique parent directories: **1**\n- Requested kernel watches: **1**\n- Recursive tree watches: **0**\n- `max_user_watches`: **131,072**\n- Observed/live watches: **130,964**\n- Numerically available: **108**\n- Inotify instances: **47 of 128**, leaving **81**\n\nTwo consecutive read-only live snapshots remained at exactly 130,964. The five largest holders account for 130,785 watches, led by the same `senpi` processes recorded in `FAIL-CLOSED.json`.\n\n### Determinism\n\nThe failure is **not deterministic under the measured pressure**:\n\n1. One requested watch fits within the reported 108-watch headroom.\n2. The v5 source Golden Path successfully armed the same one-watch observer at 17:36 and produced four valid commit receipts.\n3. The isolated regression failed around 17:38.\n4. The current pressure is still exactly 130,964, yet pressure alone does not mathematically force this one-watch call to fail.\n\nThe artifact discarded the underlying `errno`: `_os_error()` chained an `OSError`, but the driver serialized only `CommitObservationError: inotify_watch_failed`. Therefore it cannot distinguish `ENOSPC` from another `inotify_add_watch()` failure. Linux also defines `ENOSPC` as either quota exhaustion **or failure to allocate another required kernel resource**.\n\n**Evidence-backed conclusion:** fail-closing was correct, but `FAIL-CLOSED.json` overstates the cause. It proves a failed `inotify_add_watch()` under high UID pressure; it does not prove exhaustion, and current pressure does not make the failure deterministic.\n\n## Event-driven bounded alternative\n\nUse Linux directory notification without inotify:\n\n- Open each unique watched parent directory once.\n- Configure `F_NOTIFY` with `DN_MULTISHOT | DN_MODIFY | DN_CREATE | DN_RENAME`.\n- Select a queued real-time signal with `F_SETSIG`, block it before arming, and consume it through `signalfd`.\n- Preserve the existing pre-block state replay and post-event byte/inode state comparison.\n- Continue emitting the existing hash-chained `subscription_armed` and `commit_observed` receipts.\n\nThis remains kernel-event-driven, works for the synchronous atomic-replace/in-place commit patterns exercised here, requires no polling or sleeps, and consumes **zero inotify watches**. Resource use is bounded by unique parent-directory cardinality—one directory FD for this path.\n\n## Bounded-watch regression acceptance criteria\n\n1. The Golden Path uses exactly one notification resource for its one unique parent and zero recursive/tree watches.\n2. Arming occurs before mutation and persists the same initial byte/inode state.\n3. Atomic replacement produces exactly one contiguous receipt with the committed inode and SHA-256.\n4. In-place synchronous commit produces the final closed commit hash, never an intermediate hash.\n5. The existing arm-to-read race test passes through state replay without waiting for another event.\n6. Multiple watched files sharing a parent still use one directory notification resource and route by post-event state comparison.\n7. Unrelated sibling events cannot satisfy `observe()`.\n8. Lost notification, malformed state, or timeout remains fail-closed.\n9. Tests subscribe before triggering, await the exact event with a bounded timeout, and contain no sleeps or polling.\n10. The 64-test source gate and installed equivalent pass unchanged while live UID inotify usage remains at current pressure.\n11. Regression instrumentation asserts:\n    - `inotify_add_watch` calls: **0**\n    - directory notification resources: `len(unique(path.parent))`\n    - this Golden Path’s bound: **1**\n\nNo files or processes were modified during this audit."}}
