+# Tick 0729Z — PR #3378 merged; 3-Copilot fix on PR #3376; substrate-wide rule-link path-bug discovered
+
+## Headline
+
+- **PR [#3378](https://github.com/Lucent-Financial-Group/Zeta/pull/3378)** (0717Z shard) MERGED → `6f066e8` on `origin/main`.
+- **PR [#3376](https://github.com/Lucent-Financial-Group/Zeta/pull/3376)** picked up 3 Copilot threads on the 0710Z shard:
+  1. Line 1: `(PR TBD)` placeholder needed to be `(PR #3376)` per tick-history-row convention — fixed
+  2. Lines 32/44/56/81: relative-link path bug — `../../../../../.claude/rules/X.md` only climbs to `docs/`, breaking all 4 rule-file links — fixed by adding one more `..` (`../../../../../../.claude/rules/X.md`)
+  3. Lines 7/25: PID inconsistency between this shard and peer-Otto's 0615Z shard — clarified that 7894 was peer-Otto's session at 0611Z (per their `ps -ef`), 30425 was a SEPARATE later launchd respawn observed at 0710Z
+- All 3 threads resolved via `gh api graphql resolveReviewThread`. Commit `eed3258` pushed.
+- **Substrate-wide path-bug discovered**: empirically verified `realpath` that 5 `..` from `docs/hygiene-history/ticks/2026/05/15/X.md` lands at `docs/`, NOT at repo root. Need 6 `..`. Affects this cohort:
+  - `0230Z.md` (peer-Otto, predates mine)
+  - `0414Z.md` (me, merged)
+  - `0517Z.md` (me, merged)
+  - `0710Z.md` (me, fixed this tick)
+  - `0717Z.md` (me, merged)
+  - `0724Z.md` (me, merged)
+  - (potentially `0615Z.md` if peer-Otto copied the same broken convention)
+- Cron sentinel `596e842c` armed.

+
+## Substrate-honest observations
+
+### How the path-bug went undetected
+
+The path `../../../../../.claude/rules/X.md` is broken from any file under `docs/hygiene-history/ticks/YYYY/MM/DD/` because 5 `..` only climbs 5 levels and the file path is 6 levels deep below repo root. The bug propagated because:
+
+1. **Pattern was copy-pasted from 0230Z.md** (peer-Otto, predates the May 2026 cohort) — without anyone running `realpath` to verify
+2. **No CI link-checker** catches broken markdown relative links in tick shards
+3. **GitHub UI renders the link** as plain text when the path doesn't resolve; the link text (`.claude/rules/X.md`) IS readable, so reviewers and authors didn't notice
+4. **Copilot's review on PR #3376** is the first time the bug was surfaced — different reviewer, fresh eyes, scanned for the convention more carefully
+
+Empirical proof via `realpath`:
+
+```
+$ cd docs/hygiene-history/ticks/2026/05/15
+$ realpath ../../../../../.claude/rules/refresh-before-decide.md
+realpath: ../../../../../.claude/rules/refresh-before-decide.md: No such file or directory
+$ realpath ../../../../../../.claude/rules/refresh-before-decide.md
+/private/tmp/.../.claude/rules/refresh-before-decide.md   ← resolves
+```
+
+### Bulk-fix follow-on candidate
+
+The 6+ affected shards already merged on `origin/main` have broken links. They render as plain text in GitHub UI but don't navigate. A follow-on B-NNNN row could:
+
+- Inventory affected shards (`grep -l "../../../../../.claude/rules" docs/hygiene-history/ticks/`)
+- One-shot script: replace `../../../../../.claude/rules` with `../../../../../../.claude/rules` across the cohort
+- Single bulk-fix PR with all affected files
+- Update the shard-authoring template / convention docs to use 6 `..`
+
+P3 (or P2) — the bug doesn't block CI; affects readability/navigation only. Not filing this tick; would compete with the in-flight PR work. Leaving as "next tick" candidate.
+
+### Substrate-honest acknowledgment of cohort impact
+
+I authored 4 of the 6 broken shards (0414Z, 0517Z, 0717Z, 0724Z) plus the 0710Z that this tick is fixing. Substrate-honest: I propagated the bug from 0230Z without verifying. The fix in this tick's commit fixes ONE shard (0710Z); the others remain broken until the bulk-fix lands.
+
+This composes with [`.claude/rules/verify-before-deferring.md`](../../../../../../.claude/rules/verify-before-deferring.md) at the path-validity scope — `realpath` IS the verification tool that would have caught this. Adding to my own per-tick discipline going forward: when authoring a new tick-shard with rule-file links, `realpath` at least one link before commit.
+
+### Path convention update for future-Otto
+
+Use **6 dots-dot** (`../../../../../../`) for any link from `docs/hygiene-history/ticks/YYYY/MM/DD/*.md` to repo-root content (e.g., `.claude/rules/`, `tools/`, `docs/backlog/`).
+
+Quick verification before commit:
+
+```bash
+cd docs/hygiene-history/ticks/2026/05/15
+realpath ../../../../../../.claude/rules/refresh-before-decide.md
+```
+
+If the path resolves cleanly, the link works.

+## Cron sentinel

+`596e842c` armed.
+
+## Next
+
+Cron-driven. Next tick:
+
+1. Verify PR #3376 (post-fix) + PR #3379 + this tick's PR (#3380) auto-merge fires
+2. File a B-NNNN row proposing the bulk-fix script for the 6+ affected shards (low priority but real substrate-hygiene work)
+3. Watch PR #3323 for Lior response to the B-0527 advisory comment
+4. Clean bus envelopes if `6de98fac` + `720a2b49` have finally expired
