shard(tick): 2026-05-16T15:47Z — B-0462 cascade landed (PR #3897 MERGED); peer-contamination caught by branch-discipline by AceHack · Pull Request #3900 · Lucent-Financial-Group/Zeta

AceHack · 2026-05-16T15:57:22Z

Summary

Cascade chain from 1531Z commit → 1535Z PR-open → 1547Z merged confirmation. PR #3897 (B-0462 7th cycle close-row) landed at 4443c09. PR #3898 (1535Z tick shard) still auto-merging cleanly.

Peer-contamination caught: git branch --show-current at tick start reported peer Otto-CLI's branch (otto-cli-b0457-close-2026-05-16-1542z), not mine. The branch-discipline (not the env-var hook) made the silent HEAD-shift visible BEFORE any mutating operation. Recovered via git switch -c (no worktree-add pack-contention).

Rate-limit: 565 → ~555 GraphQL; 10min to reset. Extreme cost-aware tier continues; substantive observation IS the value-add for this tick (substrate-or-it-didn't-happen applies to confirmations too).

Pull request overview

Adds a new hygiene-history tick shard documenting the 15:47Z cascade confirmation for B-0462 and capturing a branch-discipline catch of peer worktree contamination.

Changes:

Adds tick shard 1547Z.md with refresh state, cascade confirmation, and peer-contamination observation.
Records operational notes on rate-limit posture and branch recovery steps.
Adds cross-references (“Composes with”) to related rules/docs/backlog items.

And 4× ../ for AUTONOMOUS-LOOP-PER-TICK.md (which resolves to docs/hygiene-history/AUTONOMOUS-LOOP-PER-TICK.md — wrong; it's at docs/AUTONOMOUS-LOOP-PER-TICK.md).

…547Z (CI lint catch); path-depth reference table (#3903) CI lint (tick-shard relative-paths) caught 7 broken links on each of PR #3898 + #3900. Root cause: from docs/hygiene-history/ticks/YYYY/MM/ DD/HHMMZ.md, root is 6 levels up (not 5). Fix-companions on the two shard branches; this shard documents the path-depth reference table so future tick-authoring (any of the 3 Otto surfaces) inherits correct depths at cold-boot: | Target | ../ count | |-------------------|-----------| | sibling shard | 0 | | docs/... | 5 | | docs/backlog/... | 5 + backlog/ | | repo root | 6 | | .claude/rules/... | 6 + .claude/rules/ | Local audit exit 0 after fix. Budget reset hit during prior tick; no longer in extreme cost-aware tier. Co-authored-by: Claude <noreply@anthropic.com>

Cron sentinel armed (was missing). 5 peer Otto-CLI sessions active; extreme cost-aware tier (975 GraphQL remaining).

…6× ../; docs/ needs 5× ../) (#3906) PR #3900 auto-merged the ORIGINAL broken-paths commit 9986e58 BEFORE the fix-push 53bc359 (to the same branch) registered. The broken 1547Z.md is now on main and was blocking PR #3898's lint check. This direct-fix-on-main re-applies the same corrections that lived on the now-orphaned 1547Z branch's fix-commit. Once merged, PR #3898 will pass lint and auto-merge. The path-depth reference table for future tick-authoring is documented in 1610Z.md (landed via PR #3903) so this class of error has wake-time substrate.

…med-dep loop closed (#3908) * fix(rules): document 3 stale-armed-PR resolution patterns in blocked-green-ci rule This session's empirical evidence (5 stale-armed PR investigations between 13:10Z and 16:33Z) clarifies three distinct resolution patterns: close-as-redundant, re-land-via-cherry-pick, and forward-signal-comment. Added a decision tree and links to the empirical instances. Composes with the forced-escalation-finds-hidden-work anchor on holding-without-named-dependency rule (PR #3901).

PRs #3897 (B-0462), #3898 (1535Z shard), #3900 (1547Z shard), #3903 (1610Z + path-depth table) all merged. PR #3906 (fix-1547z-on-main) auto-merging cleanly (22/25 SUCCESS, 2 pending). Substrate-honest lessons: - Auto-merge race (sub-case 5 of claim-acquire saturation-ceiling) - Lint check classification: broken paths on main propagate as new errors to subsequent PRs via the audit's all-shards scan - Path-depth reference table (1610Z, PR #3903) is the durable substrate fix Persistent contamination: git branch --show-current caught HEAD-shift to 5 different peer-Otto branches across 5 cron fires; no commits landed on peer branches.
