Thread disposition

#	Reviewer	Verdict	Action
1, 3	codex P1 + copilot	Already fixed in bdc56f232 (null-state skip in runOneCycle)	Reply + resolve
2	codex P2	Real per-window-vs-process limitation; full fix needs AX traversal (contradicts cheap-probe design)	Substrate-honest scope-defer reply + resolve
4	copilot	False positive. `indexOf("	")returns first
5	copilot	Already fixed in bdc56f232 (FRONTMOST_HISTORY_MAX=256 + LRU)	Reply + resolve
6	copilot	Already fixed in bdc56f232 (docstring rewrite)	Reply + resolve

Substrate-honest framing

No code change was pushed — all four substantive concerns were already in code at the PR head. Threads were stale acknowledgment work, not action work. The blocker was required_conversation_resolution holding open over threads pointing at already-shipped fixes (per the catalog in blocked-green-ci-investigate-threads.md: "stale ≠ false; just means the action window closed").

Budget state

• Session start: 136/5000 GraphQL (pure-git tier)
• Post-work: 46/5000 (12 mutations + 1 status check)

• --all-open batch poll deferred to post-reset cron tick

Pull request overview

Adds a new hygiene-history tick shard documenting the 2026-05-16T23:49Z Otto-CLI session that resolved stale PR #3956 review threads (with no code changes) so auto-merge could complete, including budget state and substrate links.

Changes:

• Adds a new tick file capturing the PR #3956 thread sweep and merge outcome.
• Records GraphQL budget usage / deferrals and the rationale for skipping --all-open.
• Links the work to relevant .claude/rules/* substrate documents.

• These .claude/rules/* links also use ../../../../../ from this directory, which resolves under docs/ rather than repo-root. Update them to ../../../../../../.claude/rules/... (consistent with other tick files in this folder).
