That is correct while corruption is fresh — but it created +a **deadlock** (issue #4469): + +1. When LadybugDB quarantines a corrupt store it leaves a `cognitive.corrupt-` + artifact in `~/.simard`. `no_quarantine` goes red and stays red. +2. The largest *substantial* quarantine is the **#2550 recovery asset** — a + corrupt store a prefix-recovery salvaged real records from — and + `remove_old_corrupt_dbs` deliberately **never** sweeps it, regardless of age. +3. So the one artifact that keeps `no_quarantine` red is exactly the one that is + protected from deletion. The probe can therefore **never** clear on its own, + `all_healthy()` never reaches `true`, and self-deploy freezes with the running + binary stuck commits behind merged `main` (the recurring + "DeployDrift — running binary is N commit(s) behind merged main" signal). + +The fix adds a **durable acknowledge path**: an operator (or, for the protected +recovery asset past the forensic window, the daemon itself) can *acknowledge* a +quarantine so the probe stops counting it — **without deleting the recovery +asset**. Acknowledgement silences the probe; retention is untouched. New, +unacknowledged corruption still reddens the probe immediately, because +acknowledgement is keyed to a specific artifact filename (which embeds the +`.corrupt-` timestamp). + +## The `.ack` sidecar convention + +Acknowledgement is recorded as a small sibling **sidecar file** next to the +quarantine artifact it acknowledges, in the resolved +[`simard_state_root()`](../../src/state_root.rs): + +``` +~/.simard/cognitive.corrupt-20260722T131600Z # the quarantine artifact +~/.simard/cognitive.corrupt-20260722T131600Z.ack # its acknowledgement sidecar +``` + +Properties: + +- **Filename-keyed.** The sidecar name is `.ack`. Because + every quarantine name carries a unique `.corrupt-` infix, an `.ack` only + ever silences the one artifact it names. A *new* corruption event produces a + new `.corrupt-` artifact with no sidecar, so `no_quarantine` re-reddens. +- **Additive, never destructive.** Writing an `.ack` never touches, moves, or + deletes the quarantine artifact. The #2550 recovery asset survives verbatim. +- **Idempotent.** Acknowledging an already-acknowledged artifact is a no-op that + succeeds. Re-running the operator command is always safe. +- **Reversible.** Deleting the `.ack` sidecar restores the pre-ack behaviour: + the artifact is counted again and `no_quarantine` reddens (assuming the + artifact is still present). + +### Sidecar payload + +The sidecar is a small, fixed marker file — the exact bytes +`acknowledged\n`. Presence of the sidecar *is* the acknowledgement; the +convention deliberately stores no structured payload, so there is nothing to +parse, version, or leak. Who acknowledged (operator vs. the guarded +autonomous auto-ack), when, and why are recorded on the **structured +tracing/OTel event** emitted at acknowledgement time, not in the sidecar.

It must live on the probe +path so the same code clears the deadlock for both the operator command and the +autonomous daemon. + +The auto-ack is narrowly scoped — it fires only for the case that can genuinely +never clear otherwise: + +- **Only** the #2550 **protected recovery asset** is eligible — the single + artifact `remove_old_corrupt_dbs` refuses to sweep: the largest quarantine + whose size is at least `CORRUPT_DB_PROTECT_MIN_BYTES` (1 MB). +- **Only** when it is **older than the forensic window** + (`CORRUPT_DB_MAX_AGE_DAYS`, 30 days) — long past the point an operator would + have acted on it. +- Every other quarantine artifact — anything fresh, anything not the protected + asset — is **never** auto-acked and still reddens the probe. + +> **Single-sourced protected-asset selection.** The "which artifact is the +> protected recovery asset" decision — largest quarantine with size ≥ +> `CORRUPT_DB_PROTECT_MIN_BYTES` — and the `CORRUPT_DB_MAX_AGE_DAYS` age gate are +> the **same** predicate and constants `remove_old_corrupt_dbs` uses in +> [`src/cmd_cleanup/disk.rs`](https://github.com/rysweet/Simard/blob/main/src/cmd_cleanup/disk.rs). +> `health.rs` reuses that selection helper and those constants rather than +> re-deriving "protected" independently, so the probe and the sweep can never +> disagree about which single artifact is protected. (This is separate from the +> corrupt-*name* predicate above; both the name predicate and the +> protected-asset selection are single-sourced.) + +When an auto-ack fires it writes the fixed-marker `.ack` sidecar and emits a +structured OTel event (WARN) recording that the source was the autonomous +daemon, the artifact name, its age, and the reason. There is no +`print!`/`println!` — the record is tracing/OTel only. The auto-ack is +reversible (delete the sidecar) and is logged so an operator can always see +that the daemon cleared the deadlock on its own. + +> **Why this is safe.** Auto-ack silences a probe; it never deletes data and +> never touches a *fresh* quarantine. A genuinely new corruption event produces +> a new, young, unacknowledged artifact that both fails the age gate and lacks a +> sidecar — so it correctly reddens `no_quarantine` and blocks the deploy. + +## Cleanup interaction (`cmd_cleanup::disk`) + +`remove_old_corrupt_dbs` +([`src/cmd_cleanup/disk.rs`](https://github.com/rysweet/Simard/blob/main/src/cmd_cleanup/disk.rs)) +is updated so acknowledgement and reclamation stay consistent: + +- **Scans the resolved state root.** The scan directory is now + [`simard_state_root()`](../../src/state_root.rs) rather than a hardcoded + `$HOME/.simard`, so a `SIMARD_STATE_ROOT` override points the sweep at the + **same** directory the probe scans and acknowledges in. (Previously the two + could diverge under an override.) +- **Skips `.ack` sidecars.** `is_ack_marker_name` sidecars are not quarantine + artifacts and are never counted or reclaimed on their own. +- **Sweeps a sidecar with its artifact.** When a quarantine artifact is reclaimed + (age cap or keep-last-N), its `.ack` sidecar, if any, is removed in the same + pass so no orphaned sidecars accumulate. +- **Preserves the #2550 recovery asset and its marker.** The largest substantial + quarantine is still never swept, and its `.ack` sidecar (from an auto-ack or a + manual ack) is preserved alongside it. Acknowledgement silences the probe; it + does **not** make the recovery asset eligible for deletion. + +## Convergence guarantee + +With the acknowledge path in place, a stuck quarantine no longer freezes +self-deploy: + +1. `no_quarantine` counts only unacknowledged artifacts, so an acknowledged + (or auto-acked protected) quarantine no longer reddens it. +2. `all_healthy()` can reach `true`, the post-deploy health check passes, and the + swapped build is accepted instead of rolled back. +3. Self-deploy converges — the running binary advances to merged `main` and the + recurring "DeployDrift — running binary is N commit(s) behind merged main" + signal stops firing. + +**Autonomy is bounded by the forensic window.** Fully autonomous convergence +happens only *after* the protected recovery asset ages past +`CORRUPT_DB_MAX_AGE_DAYS` (30 days), because the guarded auto-ack refuses to +touch it before then. While the protected asset is still inside that window, an +operator must run `simard self-health --acknowledge-quarantine` to converge — the +daemon deliberately will not silence a recent quarantine on its own. This is the +intended trade-off: the forensic window is preserved for fresh corruption, and +autonomy resumes once it has elapsed. + +A genuinely new corruption still reddens the probe and blocks the deploy, so the +safety property the probe exists to enforce is preserved. + +## See also + +- [Self-deploy API reference](./self-deploy-api.md) — the six probes, the + `simard self-health` subcommand, and `all_healthy()`. +- [Overseer deploy red-canary diagnostics](./overseer-deploy-canary-diagnostics.md) + — the paired `unit-test` gate `first_failure=` detail (#4470) that makes the + *other* self-deploy blocker diagnosable. +- [Reconcile & self-deploy](../concepts/reconcile-and-self-deploy.md) — what + "healthy" means and the end-to-end deploy flow. +- [Clear a stuck memory quarantine](../howto/clear-a-stuck-memory-quarantine.md) + — the operator runbook. diff --git a/mkdocs.yml b/mkdocs.yml index c15fdaf6e..3c2a960f7 100644 --- a/mkdocs.yml +++ b/mkdocs.yml @@ -232,6 +232,7 @@ nav: - Diagnose and Recover Lost Creative-Ideas Goals: howto/diagnose-lost-creative-ideas-goals.md - Clean Fixture Leaks: howto/clean-fixture-leaks.md - Verify and Roll Back a Self-Deploy: howto/verify-and-roll-back-a-self-deploy.md + - Clear a Stuck Memory Quarantine: howto/clear-a-stuck-memory-quarantine.md - Verify and Repair PATH-Entrypoint Parity: howto/verify-path-entrypoint-parity.md - Run Self-Deploy from Any Directory: howto/run-self-deploy-from-any-directory.md - Check for Updates: howto/check-for-updates.md @@ -329,6 +330,7 @@ nav: - amplihack Freshness Gate: reference/amplihack-freshness-gate.md - Multi-Binary Self-Update: reference/multi-binary-self-update.md - Self-Deploy API: reference/self-deploy-api.md + - Self-Deploy Quarantine-Acknowledge: reference/self-deploy-quarantine-acknowledge.md - Self-Deploy Source Prep & Warm Target Dir: reference/self-deploy-source-prep.md - State-Root Resolution: reference/state-root-resolution.md - Operator Read State-Root Contract: reference/operator-read-state-root-contract.md diff --git a/src/cmd_cleanup/disk.rs b/src/cmd_cleanup/disk.rs index a08a22e2f..c929b3c56 100644 --- a/src/cmd_cleanup/disk.rs +++ b/src/cmd_cleanup/disk.rs @@ -382,25 +382,34 @@ pub(crate) fn is_corrupt_quarantine_name(name: &str) -> bool { /// The age cap alone leaves a burst of *young* quarantines untouched for a week /// (this host saw 88 MB / 112 artifacts accumulate); the keep-last-N cap bounds /// that growth immediately while preserving the most recent forensic snapshots. -pub fn remove_old_corrupt_dbs(report: &mut CleanupReport) { - let Some(home) = std::env::var_os("HOME") else { - return; - }; - let simard_dir = PathBuf::from(home).join(".simard"); - let Ok(entries) = std::fs::read_dir(&simard_dir) else { - return; - }; - let max_age = std::time::Duration::from_secs(CORRUPT_DB_MAX_AGE_DAYS * 24 * 3600); - let now = std::time::SystemTime::now(); +/// A quarantine candidate discovered under the scan directory: its path, whether +/// it is a directory-backed store, its size in bytes, and its mtime. +struct QuarantineCandidate { + path: PathBuf, + is_dir: bool, + size: u64, + modified: std::time::SystemTime, +} - // Collect every quarantine candidate with its size + mtime so we can apply - // the age cap, the keep-last-N cap, AND the largest-asset protection over the - // full set (read_dir order is unspecified, so we cannot rank by iteration - // order).

Additive, non-breaking. - Delegate the quarantine-name predicate in self_deploy/health.rs and self_deploy/quarantine_ack.rs to the canonical crate::cmd_cleanup::is_corrupt_quarantine_name, removing two identical copies that the comments already warned had to be kept in sync (drift hazard eliminated; single source of truth). - Fix stale doc comments in quarantine_ack.rs: drop the obsolete "implementation is TODO" note (now implemented) and correct the ACK_MARKER_BYTES comment that mislabeled the payload as an upper bound. No behavior change. Build clean; clippy clean; self_deploy, cmd_cleanup, quarantine_ack, self_relaunch lib tests and self_deploy_convergence integration test all pass.

That is correct for production — the sweep and the self-health `no_quarantine` probe must scan the same resolved root — but it coupled the cmd_cleanup sweep tests to the process-global `SIMARD_STATE_ROOT` env, which many lib tests mutate under unrelated serial keys. Under the full parallel suite a concurrent setter redirected the scan dir, so the sweep found nothing and four tests failed (aged/keep-last-N quarantines "not swept"). Decouple the sweep logic from state-root resolution: add path-injected `remove_old_corrupt_dbs_in(scan_dir, report)` and have the public `remove_old_corrupt_dbs` delegate to it with the resolved root. Drive all sweep tests through the injected variant against a tempdir, removing every `HOME`/`SIMARD_STATE_ROOT` mutation from them. The tests are now deterministic and free of cross-test env races. The `corrupt_db_sweep_scans_resolved_state_root` wiring test still exercises the public wrapper's env resolution.

Security (#4469): log auto-ack and manual-ack quarantine basenames via `?name` (Debug) instead of `%name` (Display) in self_deploy::health and operator_cli::self_health. A quarantine basename is an untrusted on-disk filename that may contain newlines/control chars; under the default non-JSON tracing subscriber, logging it raw would permit log-line forgery. 2. CI portability: the merge commit accidentally captured machine-specific absolute paths (/home/azureuser/...) in .github/hooks/amplihack-hooks.json, which break the hooks on CI and other checkouts. Restore the portable repo-relative paths from main.

The cleanup sweep reclaims both the top-level state root and the live-store `state/` subdir, but the self-health `no_quarantine` probe / auto-ack only scanned `state/`, so the probe and sweep could disagree on where quarantines live. Single-source the scan-dir set in `state_root::quarantine_scan_dirs` (deduped) and drive BOTH the sweep and the probe/auto-ack from it, so they can never diverge. Minor — orphaned `.ack` sidecars never reclaimed. Add `reclaim_orphaned_ack_sidecars`: a marker whose parent quarantine no longer exists is now reclaimed (regardless of remaining candidates), so stale markers cannot accumulate unbounded. LOW-1 — untrusted quarantine basename written unescaped to stderr / CleanupReport. Route operator-facing paths in the corrupt-DB sweep through the shared `sanitize_gate_detail` control-char strip (re-exported from `self_relaunch`) to prevent terminal/log forgery. LOW-2 — auto-ack `marker` field logged via Display while the sibling `artifact` is Debug-escaped. Log `marker` via `?marker` (Debug) for consistent control-char escaping. Tests: rework the top-level-scan test into a probe/sweep parity contract, add an orphan-`.ack`-reclaim test. All changed-module lib tests (78) + self_deploy_convergence (4) pass; clippy clean.

All consumers From d1163b44c4665b741f0917f273308605d9cce98a Mon Sep 17 00:00:00 2001 From: rysweet Date: Thu, 23 Jul 2026 08:15:08 +0000 Subject: [PATCH 09/13] Step 18b: apply non-blocking review polish (S5/S6/S7) for PR #4488 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Address optional philosophy/code-review notes from the Step 16 reviews. All items are non-blocking; the PR was already APPROVE with 0 blocking issues. S6: relocate the shared control-char log sanitizer out of `self_relaunch::gates` into a neutral `util::log_sanitize` module (`sanitize_to_single_line`). This removes the `cmd_cleanup::disk` -> `self_relaunch` cross-module coupling for a generic sanitizer; both the canary gate detail (#4470) and the cleanup path log (#4469, LOW-1) now depend on util instead. Sanitizer unit tests moved with it. S5: the test-only `count_quarantine_files` helper now delegates to the production `tally_quarantine_files` scan (summing fresh + retained) instead of duplicating the read_dir / acknowledgement filter logic, eliminating drift risk between the test helper and the live probe path. S7: document the intentional `let _ =` discard of `auto_ack_stuck_recovery_asset` in the no_quarantine probe loop (best-effort; errors logged internally). Also refresh docs/reference/self-deploy-quarantine-acknowledge.md to describe the actual production `tally_quarantine_files` scan rather than the now test-only helper. S4 (narrow `ack_marker_path` visibility) intentionally deferred: it is a documented public API and is consumed by the `self_deploy_convergence` integration test (a separate crate that requires `pub`), so narrowing to `pub(crate)` would break both. Verified: cargo test log_sanitize (3), self_relaunch::gates (10), self_deploy::health (20), quarantine_ack (10), cmd_cleanup (40), self_deploy_convergence e2e (4) — all pass.

A stuck quarantine under /state/ (the primary location the de-forked backend drops corrupt snapshots) could therefore never be cleared manually, leaving self-deploy frozen despite a 'success' from the command. Fix: add a path-injected state_root::quarantine_scan_dirs_under and iterate it in acknowledge_all_present_quarantines so all three consumers share the identical directory set. Adds acknowledge_all_covers_state_subdir regression test. F2 (MEDIUM): the automatic auto-ack's aged-gate (>= CORRUPT_DB_MAX_AGE_DAYS) is mutually exclusive with the probe's fresh-gate (mtime >= recent window_start), so the aged asset it targets is always counted 'retained', never 'fresh', and cannot change the no_quarantine verdict. Comments/docs claiming it 'breaks the stuck deadlock so the probe can converge' contradicted the probe's own fresh-window semantics (proven by no_quarantine_passes_with_only_historical_quarantines_in_state_dir). Corrected the code comments and reference/howto docs to describe the auto-ack accurately as defense-in-depth (the fresh-window logic is the primary convergence mechanism; the manual command clears genuinely-stuck fresh quarantines).
