…estigation cleared 4 standard agent loops Negative-finding substrate: cleared Lior, Riven, Codex/Vera, Copilot loops + lane-allocator + git worktree prune + git gc.pruneexpire as suspects for the worktree-pruning race observed in tick 0414Z. Source remains untraced; remaining candidates (claude-loop, otto-forward, peer-Otto, .git/hooks/, macOS system services) listed for next-tick investigation. Investigation-budget discipline: 12 tool calls; diminishing returns; next-tick continuation. Co-Authored-By: Claude <noreply@anthropic.com>

Pull request overview
Adds the 2026-05-15 05:24Z tick-history shard documenting merges of PRs #3361/#3362 and capturing the current state of the worktree-prune-race investigation (including cleared suspects and remaining candidates).
Changes:
- Introduces a new tick shard file
0524Z.mdwith the required pipe-row header plus an H1-rich narrative body. - Records investigation results for the worktree-prune-race incident and enumerates remaining suspects for follow-up.

- The markdown link to
.claude/rules/verify-before-deferring.mduses../../../../../..., which appears to be one directory short from this file location and will resolve to a non-existentdocs/.claude/...path. Update the link to a correct relative (or repo-root-relative) path.
This composes with [`.claude/rules/verify-before-deferring.md`](../../../../../.claude/rules/verify-before-deferring.md) — instead of writing "next tick I'll investigate this", THIS tick did partial investigation and recorded which candidates are now cleared.

| The investigation consumed roughly 12 tool calls this tick. Per [`.claude/rules/holding-without-named-dependency-is-standing-by-failure.md`](../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md), this is a real substantive activity (NOT Holding). However, returns-on-investigation-budget diminish quickly: each cleared candidate narrows the suspect space by maybe 15%, and the remaining-candidates list still has ~6 entries. The remaining inspection effort would be best targeted to higher-likelihood candidates (peer-Otto and `.git/hooks/`) in a future tick. | ||

| ### Negative-finding substrate is still substrate | ||
|
|
||
| Some investigations land "we ruled out N candidates". That IS substrate-honest progress — the suspect space is smaller, future-Otto starts narrower. Not every tick lands a positive answer; the discipline is to write down WHAT WAS RULED OUT so the next tick doesn't re-trace. | ||
