+Pure-git tick. PR #3814 (last tick's B-0346 audit shard) merged — peer Otto opened the PR for the branch I pushed but couldn't PR due to rate-limit exhaustion. NEW convergence pattern: peer cross-lane PR-opening closes rate-limit gaps.

+## Pull request overview
+
+Adds a new hygiene-history tick shard documenting the 2026-05-16T07:45Z “pure-git” tick, including refresh state, the peer-assisted PR-opening pattern observed for PR #3814, and the operational rationale/visibility signals for the session.
+
+**Changes:**
+- Added a new tick entry capturing the 07:45Z state (rate-limit at 0/5000, sentinel alive, `origin/main` advanced).
+- Documented the new “peer cross-lane PR-opening” convergence pattern used to bridge rate-limit exhaustion.
+- Recorded the pure-git operational rationale and close-out visibility bullets.

+# PR #3818: rule(holding-discipline): cascade-saturation empirical anchor + pure-git compatibility + sub-case 5
+
+## PR description
+
+## Summary
+
+Three edits to `.claude/rules/holding-without-named-dependency-is-standing-by-failure.md` based on this session's empirical evidence:
+
+1. **Concrete-artifact definition** expanded to cover pure-git tier (branch-pushed-no-PR counts for counter reset)
+2. **Cascade-saturation empirical anchor** sub-section — rule operated correctly through 4 cycles this session; validates 5 properties including multi-cycle non-accumulation
+3. **NEW sub-case 5 discovered during authoring**: peer-side destructive git operations (`git reset --hard`, etc.) discard unstaged tracked-modifications. First authoring attempt of THIS commit was destroyed; re-application IS the empirical proof. Mitigation: commit immediately after Edit during peer saturation.
+
+Recursively self-validating: the meta-fallback's claim ("ALWAYS works because session behavior is observable") is proven BY the act of authoring it. The commit IS the session's behavior being documented.
+
+Composes with `refresh-world-model-poll-pr-gate.md` (rate tiers) + `claim-acquire-before-worktree-work.md` (saturation-ceiling sub-cases — sub-case 5 to land there in follow-up).

+## Pull request overview
+
+Documentation-only edits to a Claude rules file that codifies session-empirical observations about cascade-saturation behavior and a newly-discovered worktree-borrow failure sub-case. Also appends a resolution table to backlog row B-0557.

+### Thread 1: docs/backlog/P3/B-0557-audit-backlog-status-drift-quality-improvements-2026-05-16.md:92 (resolved)
+
+**@copilot-pull-request-reviewer** (2026-05-16T08:02:32Z):
+
+This closure still asserts that the cwd-independent acceptance bullet is complete, but the shipped implementation only resolves the repo root via `git rev-parse` from the current working directory and falls back to `process.cwd()` outside a Git repo. That does not satisfy the row’s existing `cd /tmp && bun /path/to/...` acceptance criterion, so either narrow the acceptance text/resolution to “from repo subdirectories” or land the import.meta-based root detection before closing the row.

+# PR #3821: fix(B-0557): truly cwd-independent — import.meta.dir fallback
+
+## PR description
+
+## Summary
+
+- Closes the scope gap that Copilot flagged on [PR #3819](https://github.com/Lucent-Financial-Group/Zeta/pull/3819): slice 3's cwd-independence acceptance bullet (\`cd /tmp && bun /path/to/...\`) was only partially shipped — `git rev-parse --show-toplevel` from /tmp fails (no git repo), and my fallback to `process.cwd()` returned /tmp which has no backlog.
+- Fix: when `git rev-parse` fails, fall back to `path.resolve(import.meta.dir, "../..")`. The tool lives at `<repo>/tools/hygiene/X.ts` so two levels up reaches the repo root regardless of cwd.
+
+## Verification
+
+**Smoke from /tmp** (the original failing case):
+
+```
+$ cd /tmp && bun /path/to/tools/hygiene/audit-backlog-status-drift.ts --json | head -5
+# Now produces the same 33+ candidate output as running from the repo root
+# (was previously empty `[]`).
+```
+
+## Test plan
+
+- [x] `bun test` → 20 pass / 0 fail / 40 expect calls (no regression)
+- [x] Smoke from /tmp now produces 33+ candidates (was empty)
+- [x] `git rev-parse` still preferred when available (subdir-of-repo case)
+- [x] Closes the scope-honesty gap on PR #3819
+
+## Unblocks PR #3819
+
+Once this PR lands, [PR #3819](https://github.com/Lucent-Financial-Group/Zeta/pull/3819) (B-0557 close-row) can resolve its outstanding thread — slice 3's acceptance is now fully shipped, not partial.

+## Pull request overview
+
+This PR completes B-0557 slice 3’s “cwd-independence” guarantee for `tools/hygiene/audit-backlog-status-drift.ts` by making repo-root detection work even when invoked from outside any git worktree (e.g., `/tmp`), ensuring backlog-relative reads and `existsSync` checks remain correct.
+
+**Changes:**
+- Update `detectRepoRoot()` to prefer `git rev-parse --show-toplevel`, but when that fails, fall back to deriving the repo root from the script’s own location via `import.meta.dir`.
+- Add a hygiene-history tick log entry documenting the related audit/close activity.

+# PR #3957: backlog(B-0580): Enterprise GitHub ruleset management — new layer above org/individual mapping
+
+## PR description
+
+## Summary
+
+Files B-0580 — Enterprise GitHub ruleset management work-stream. Per Aaron 2026-05-16, after creating the first enterprise-level ruleset (#16490134) under the 30-day Enterprise trial: the Enterprise tier adds a THIRD ruleset layer above org + per-repo, multiplying the existing ruleset-divergence smell from B-0427.
+
+## Why
+
+Two reframings:
+1. **Surface expansion** — was 2 layers (org/individual), now 3 (enterprise/org/individual). Cross-layer rule conflicts become a real failure mode without coherent governance
+2. **DV2.0 ruleset-divergence smell composes** per `dv2-data-split-discipline-activated.md` — the smell was known for repo-split (B-0427); Enterprise multiplies it
+
+## 5-slice decomposition
+
+- Slice 1: `tools/github/list-rulesets.ts` — REST enumeration at all 3 layers
+- Slice 2: manual audit of #16490134 + any other enterprise rulesets + LFG org rulesets + Zeta repo rulesets
+- Slice 3: `tools/github/audit-ruleset-divergence.ts` — cross-layer diff, flag conflicts
+- Slice 4: `docs/governance/RULESETS.md` — authoritative policy doc (which rule belongs at which layer)
+- Slice 5 (deferred): `tools/github/apply-rulesets.ts` — policy-as-code apply
+
+## Composes with
+
+- [B-0427](docs/backlog/) (repo-split axis 3 — Code/English with ruleset-divergence smell)
+- [B-0572](https://github.com/Lucent-Financial-Group/Zeta/pull/3952) (LFG GitHub tier decision — Enterprise trial that created the layer)
+- `.claude/rules/dv2-data-split-discipline-activated.md` (the smell-detection framework)
+- `.claude/rules/methodology-hard-limits.md` (rulesets ARE policy-as-code substrate for governance hard-limits)
+
+## Caveat re scope
+
+Enterprise-layer writes (slice 5) require `admin:enterprise` scope — current local PAT lacks it. Slices 1-4 work with `read:org` scope (which the current PAT has). Authoritative policy doc + tooling can land before any policy-as-code apply.

+
+Adds a new P2 backlog entry (B-0580) tracking enterprise-level GitHub ruleset management as a third governance layer above existing org/individual rulesets, and registers it in the main backlog index.
+
+**Changes:**
+- New backlog doc B-0580 describing motivation, slices, acceptance criteria, and first-discovery findings for the new enterprise ruleset created (`16490134`).
