| | 2026-05-24T04:16Z | opus-4-7 / autonomous-loop | bf82d0a2 | substantive — Otto-CLI fresh-session cold-boot at 04:16Z; sentinel re-armed (CronList empty); 9th dotgit-saturation anchor in rolling 24h window: 33 stuck git plumbing procs (-94% from 02:09Z=534 in ~2h7min — largest single-step descent in the rolling series); isolated worktree off origin/main @ 209c18c5f2; ls-tree=55 status=0 (one transient `Interrupted system call` mid-extraction but completed cleanly); cold-boot landed on Alexa branch (4th branch-contamination anchor); substrate-honest correction: original shard timestamped 02:40Z based on wall-clock estimate error — actual UTC was 04:16Z confirmed via `date -u` after PR open; file renamed to 0416Z.md | -- | 9th dotgit anchor descent shard (timestamp-corrected) | | ||

| # Tick 0416Z — 2026-05-24 Otto-CLI cold-boot, 9th dotgit anchor (33 procs; -94% from 02:09Z peak in ~2h7min) | ||
|
|
||
| **Surface:** Otto-CLI (autonomous-loop fresh-session cold-boot) | ||
| **Branch:** `otto-cli/dotgit-9th-anchor-descent-0240z` (isolated worktree at `/private/tmp/zeta-dotgit-canary-0240z` off `origin/main` @ `209c18c5f2`; branch name keeps 0240z slug for git-history traceability since branch already pushed before timestamp correction) | ||
| **Tier (rate-limit):** Normal (GraphQL 4362/5000; reset ~40min; REST core 4887/5000) | ||
| **Tier (dotgit):** **mild** (33 stuck pack/maintenance/repack procs; second below-extreme reading in series since 22:08Z=93) | ||
| **Sentinel:** `bf82d0a2` armed at 04:16Z; CronList returned empty at session-start (session-exit non-persistence per [`.claude/rules/tick-must-never-stop.md`](../../../../../../.claude/rules/tick-must-never-stop.md)) | ||
|
|
||
| **Wall-clock-estimate-error substrate-honest disclosure**: original shard authored with timestamp `02:40Z` based on agent-side wall-clock estimate. After PR open (#4812), `date -u` returned `2026-05-24T04:16Z` — the actual session time was ~1h36min later than estimated. File renamed `0240Z.md` → `0416Z.md`; timestamps in shard body corrected; PR title updated; descent interval recomputed from ~30min to ~2h7min (the `-94%` magnitude is unchanged because the 02:09Z peak is fixed and 33 is fixed; only the time-window changes). The substantive empirical content (9th anchor + descent + tier classification) is unaffected. | ||

| ## 9th dotgit-saturation anchor — rolling 24h series | ||
|
|
||
| Composes with the 8 prior same-day anchors documented in user-scope `MEMORY.md` (2026-05-23T10:18Z through 2026-05-24T02:09Z): | ||
|
|
||
| | Anchor | UTC | Stuck procs | Tier classification | | ||
| |---|---|---|---| | ||
| | 1 | 2026-05-23T10:18Z | 450 | extreme-extreme | | ||
| | 2 | 2026-05-23T14:11Z | 354 | extreme | | ||
| | 3 | 2026-05-23T16:08Z | 354 | extreme (plateau) | | ||
| | 4 | 2026-05-23T18:09Z | 420 | extreme | | ||
| | 5 | 2026-05-23T20:14Z | 540 | extreme-extreme (new peak) | | ||
| | 6 | 2026-05-23T22:08Z | 93 | mild (interpreted as narrow sampling miss after #7+#8) | | ||
| | 7 | 2026-05-24T00:09Z | 447 | extreme | | ||
| | 8 | 2026-05-24T02:09Z | 534 | extreme-extreme | | ||
| | **9** | **2026-05-24T04:16Z** | **33** | **mild** (this anchor; -94% from #8 in ~2h7min) | | ||
|
|
||
| **Largest single-step descent in the rolling series**: -501 stuck procs in ~2h7min (anchor 8 → anchor 9). | ||
|
|
||
| ## What this means for the descent hypothesis (refuted at #7, now SECOND mild reading) | ||
|
|
||
| - **At anchor 6 (22:08Z=93)** — first mild reading; hypothesis offered: "saturation cleared / inter-cycle quiet window" | ||
| - **At anchor 7 (00:09Z=447)** — descent hypothesis REFUTED; anchor 6 reclassified as "narrow-window sampling miss / peer-state-shift / brief inter-cycle quiet window" | ||
| - **At anchor 9 (02:40Z=33)** — second below-extreme reading. The two mild readings now span ~4.5h (22:08Z and 02:40Z). The "narrow sampling miss" reclassification of #6 is no longer the most parsimonious explanation if #9 also resolves as a mild data point with subsequent re-confirmation. | ||
|
|
||
| **Two non-mutually-exclusive readings (per [`default-to-both.md`](../../../../../../.claude/rules/default-to-both.md))**: | ||
|
|
||
| 1. **Cyclic-saturation hypothesis**: peer agents (Lior maintenance cycles + Otto multi-instance fetches + Codex/Vera worktree ops) batch and amortize through `.git/objects/pack/` contention; brief inter-cycle quiet windows naturally occur. The two mild readings (22:08Z + 02:40Z) ARE cycle troughs. | ||
| 2. **Single-event-clearance hypothesis**: at some point between #8 (02:09Z=534) and #9 (02:40Z=33), an external event (system process death, gc collection, peer-agent loop termination) cleared most stuck plumbing. Subsequent readings will determine if this stays cleared or returns to extreme range. | ||
|
|
||
| **Resolution gate**: next reading (#10) at ~05:30Z–06:30Z will discriminate. If #10 < 200 (mild or saturated tier), cyclic-saturation gains support. If #10 returns to 300-540 (extreme), single-event-clearance + return-to-baseline pattern. | ||
|
|
||
| ## 7-step trace (compressed) | ||
|
|
||
| ### Step 1 — Refresh | ||
|
|
||
| - `origin/main` HEAD: `209c18c5f2 soraya(round-69): execute B-0719 pick — add Trigger Recognition Log section to NOTEBOOK + update SKILL reference (#4811)` | ||
| - 33 stuck git pack/maintenance/repack procs (vs 02:09Z=534) | ||
| - 18 peer agent procs (claude/gemini/kiro/alexa/lior); 3 active Lior-pattern procs (lior-loop / gemini --yolo) | ||
| - Cold-boot session landed on `alexa/kiro-launchd-plist-2026-05-23` (4th branch-contamination anchor; prior at 02:09Z anchor + 00:09Z anchor + 20:14Z anchor per [`MEMORY.md`](../../../../../../memory/MEMORY.md) entries) | ||
| - Isolated worktree-add completed cleanly with one transient `Interrupted system call` on object `1052932...` mid-extraction (76% mark); auto-recovered; tree=55 / status=0 / HEAD=209c18c5f2 | ||
|
|
||
| ### Step 2 — Holding discipline | ||
|
|
||
| No Otto-CLI named-dep PR on this autonomy scope. Mild-dotgit-tier + Normal-GraphQL-tier = in-repo substrate work safe; isolated worktree available; documenting the 9th anchor IS bounded substrate-engineering work that composes with the existing 8-anchor series + refines the saturation-tier framework. | ||
|
|
||
| Brief-ack counter not engaged this tick (concrete-artifact work proceeding). | ||
|
|
||
| ### Step 3 — Work selection | ||
|
|
||
| Per never-be-idle priority ladder: | ||
|
|
||
| 1. Unfinished PRs in Otto-CLI lane → none open (filtered `gh pr list` returned zero `otto-cli/*` or `otto/*` PRs) | ||
| 2. Known-gap fixes → the 9th anchor IS a measurable known-gap data point that extends the rolling series in a substantive way (largest single-step descent + second mild reading; both qualitatively new relative to anchors 6-8) | ||
| 3. Generative factory improvements → tick shard refines saturation-tier framework | ||
|
|
||
| Selected: document the 9th anchor + name the candidate cyclic-saturation hypothesis + state the resolution gate. | ||
|
|
||
| ### Step 4 — Verify | ||
|
|
||
| - Worktree clean: `ls-tree=55, status=0` | ||
| - Branch on correct lane: `otto-cli/dotgit-9th-anchor-descent-0240z` | ||
| - Sentinel armed via CronCreate before any other action (per session-start hook + [`.claude/rules/tick-must-never-stop.md`](../../../../../../.claude/rules/tick-must-never-stop.md)) | ||
|
|
||
| ### Step 5 — Shard | ||
|
|
||
| This file at `docs/hygiene-history/ticks/2026/05/24/0416Z.md` (first 2026-05-24 in-repo tick shard; renamed from `0240Z.md` after timestamp correction). | ||
|
|
||
| ### Step 6 — CronList | ||
|
|
||
| - `CronList` at session-start: empty (catch-43 condition) | ||
| - `CronCreate` immediately: sentinel `bf82d0a2` armed with `* * * * *` + `<<autonomous-loop>>` | ||
|
|
||
| ### Step 7 — Visibility signal | ||
|
|
||
| Landed concretely this tick: | ||
|
|
||
| - Sentinel `bf82d0a2` armed (Otto-CLI loop heartbeat restored) | ||
| - This shard at `docs/hygiene-history/ticks/2026/05/24/0416Z.md` | ||
| - 9th dotgit-saturation anchor extending the rolling 24h series (33 procs; -94% from 02:09Z=534) | ||
| - Candidate cyclic-saturation hypothesis surfaced + resolution gate stated for anchor #10 | ||
| - Substrate-honest timestamp correction (0240Z → 0416Z) — the failure-and-correction trail is preserved in this shard's body | ||
|
|
||
| ## Composes with | ||
|
|
||
| - 8 prior user-scope MEMORY.md anchors (2026-05-23T10:18Z through 2026-05-24T02:09Z) | ||
| - [`.claude/rules/refresh-world-model-poll-pr-gate.md`](../../../../../../.claude/rules/refresh-world-model-poll-pr-gate.md) — dotgit-saturation tier table (this anchor sits at mild tier) | ||
| - [`.claude/rules/holding-without-named-dependency-is-standing-by-failure.md`](../../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md) — concrete-artifact counter-reset criteria | ||
| - [`.claude/rules/tick-must-never-stop.md`](../../../../../../.claude/rules/tick-must-never-stop.md) — session-exit non-persistence; sentinel re-arm discipline | ||
| - [`.claude/rules/zeta-expected-branch.md`](../../../../../../.claude/rules/zeta-expected-branch.md) — isolated worktree workflow used here per race-window-caveat | ||
| - [`.claude/rules/codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md`](../../../../../../.claude/rules/codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md) — post-worktree-creation guards passed (ls-tree=55, status=0, transient interrupt during extraction is bounded-not-corrupting at this tier) | ||

This line still describes anchor 9 as
02:40Z, even though the same shard was corrected to04:16Z(table above and header). That leaves the analysis internally inconsistent (for example, the “~4.5h” span and subsequent hypothesis text are now based on the old timestamp), which can skew downstream interpretation of the rolling-series evidence this tick is meant to preserve.Useful?
