…; FP-rate pattern noted Twenty-seventh tick. Cost-aware tier. Audited B-0509: - tool path tools/routines/install.ts exists (for B-0448 slice 1) - B-0509-specific 'cloud-schedule' references absent via grep - Same shape as B-0418 last tick: shared-tool path FP Two consecutive 2nd-FP-class verifications. Hypothesis filed for peer's audit-tool improvement lane: add a 'feature-grep' sub-check scanning artifacts for acceptance-named identifiers. Audit progress: 17/38 triaged. ~21 remaining.

Pull request overview
Adds a tick log under docs/hygiene-history/ticks/2026/05/16/0727Z.md documenting a backlog drift audit. The tick verifies B-0509 as a second false-positive class (shared-tool-path FP) and notes an emerging FP-rate pattern with a hypothesis for the audit tool.
Changes:
- New tick file recording audit result for B-0509 (2nd FP class, leave open)
- Tabulates triage progress and an empirical FP-rate observation across B-0418 and B-0509
- Files a hypothesis for a feature-grep sub-check in the audit tool

Codex flagged: B-0159 appeared in both class 1 (pure drift) AND class 4 (multi-slice all children closed) — mutually exclusive categories. B-0159 is class 4 (per tick 1640Z re-classification); class 1 listing was stale carry-over. Class 1 count: 9 → 8. Total triaged: 17 → 16. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Closing as superseded —
So main's version reflects a decision that OVERTURNED this PR's B-0159 removal — likely a subsequent tick re-added B-0159 to class 1. This PR represents an alternate-history branch where the removal stuck. Following the stale-armed-PR resolution pattern from PR #3910:

B-0509 verified as 2nd FP class. Two consecutive shared-tool-path FPs (B-0418 + B-0509). Hypothesis filed for peer's audit-tool improvement: feature-grep sub-check.
