Pull request overview

Adds a new research “shadow lesson log” documenting the purpose and operational value of the deferred-to-human label, as a decomposed subset of #4817.

Changes:

  • Add a 2026-05-24 shadow lesson log describing when/why to use the deferred-to-human label.
  • Capture implications for agent behavior around deferral and sensitive-data scenarios.

…ss-lane (zero FPs) (#4937)

* docs(hygiene): tick 1405Z — 3 BLOCKED+resolve-threads PRs audited cross-lane (zero FPs)

Otto-CLI background-worker session-start cold-boot at 14:05Z. CronList
returned empty (session-exit non-persistence); sentinel a695b60e re-armed
before substrate work per .claude/rules/tick-must-never-stop.md.

poll-pr-gate-batch.ts --all-open returned 37 open PRs:
- 3 with nextAction=resolve-threads: #4934, #4931, #4878
- 34 with nextAction=rebase (outside thread-resolution scope)

All 3 thread-action PRs on lior-* branches (cross-lane). Per lane
discipline + 0441Z precedent (yesterday's 8-PR cross-lane audit ruling),
disposition is audit + document; no cross-lane checkout/push.

Findings: 18 threads inspected (5 deep, 3 sampled), zero FPs:
- #4934: Copilot P1 factual drift in shadow lesson log (wrong PR
  numbers + wrong deferred-to-human attribution vs 0441Z substrate)
- #4931: Codex P1 frontmatter schema drift (archive_tool key replaced
  with Python snippet, breaks downstream tooling)
- #4878: 16 threads spanning docs/pr-discussions/ — schema drift,
  count mismatches, link style; auto-merge armed but
  required_conversation_resolution gates the merge

Counter discipline (holding-without-named-dependency rule):
concrete artifact produced; counter reset condition #3 satisfied.

* docs(hygiene): fix 1405Z shard schema + broken precedent link (PR #4937 threads)

Three reviewer findings on docs/hygiene-history/ticks/2026/05/25/1405Z.md
(all verified concrete via path resolution + README schema check):

1. **Schema** (Copilot, line 3): missing 6-column pipe-row as first non-empty
   line per docs/hygiene-history/ticks/README.md "Shard file schema" section.
   Fixed by prepending the canonical pipe-row format matching the validator
   at tools/hygiene/check-tick-history-shard-schema.ts.

2. **Broken link** (Codex P2 + Copilot, line 20): `../../24/0441Z.md` resolves
   to `docs/hygiene-history/ticks/2026/24/0441Z.md` (month missing). Correct
   relative path from `2026/05/25/1405Z.md` is `../24/0441Z.md` (one `..` up
   from `25` to `05`, then `/24/0441Z.md`). Target file confirmed present at
   `docs/hygiene-history/ticks/2026/05/24/0441Z.md`.

3. **Same broken link** also appears in the new pipe-row added by fix #1;
   used `../24/0441Z.md` directly there.

Verified via:
- ls confirms link target exists
- awk confirms L1 IS the pipe-row
- grep confirms 0 remaining broken `../../24/` patterns
- schema validator output confirms 1405Z.md NOT in violations list

Cross-instance peer Otto-CLI PR #4937 unresolved threads (1407Z autonomous-
loop tick continuing peer Otto-CLI's 1405Z lane work; same Otto-CLI identity
per agent-roster-reference-card.md).

…pe per Copilot finding

The shadow lesson log claimed:
- Privacy cluster = #4733/#4730/#4727 — wrong (verified against 0441Z tick shard: actually #4733/#4735/#4737/#4739)
- Cluster received deferred-to-human label — wrong (verified against 1333Z tick shard: only #4816 was labeled)

Corrected to match recorded substrate; added anchors to 0441Z + 1333Z tick shards.

Copilot finding verified real per direct inspection of cited substrate (docs/hygiene-history/ticks/2026/05/24/0441Z.md + 1333Z.md).

Fixed in cf522cae via REST API bypass (avoids worktree pack-dir contention with 3-proc Lior peer activity per .claude/rules/codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md):

Per .claude/rules/blocked-green-ci-investigate-threads.md verify-before-fix discipline.

…ndition vacuous; 1405Z precedent re-applied (#4945)

* docs(hygiene): tick 1539Z — 43 open PRs all DIRTY+cross-lane; task condition vacuous; 1405Z precedent re-applied

Otto-bg-worker fresh task-fired session (~1h34 after 1405Z Otto-CLI audit).
Task brief gate=BLOCKED+resolve-threads matches ZERO open PRs — all 3 from
1405Z (#4878/#4934/#4931) merged within 32-67min of that audit.

Current state: 43 open PRs (up from 37); all DIRTY (need rebase); all
lior-* surface; ~10 with failed required checks (rebase alone wouldn't
move them to CLEAN); 4 with auto-merge already armed.

Disposition: audit-only per 1405Z precedent + 0441Z 2026-05-24 precedent.
Constitutional rules (lane discipline + runtime-script guard + counter
discipline) win over task-brief framing per no-directives.md.

Build gate: dotnet build -c Release → 0/0 in 26.4s.
Sentinel: 877abe32 armed at session-start per tick-must-never-stop.md.

Counter reset condition #3 satisfied (concrete artifact: shard + sentinel
re-arm + build verify + 43-PR snapshot + 1405Z follow-up + Tier-5 spot
check on #4787).

* fix(1539Z-shard): reconcile counts with enumerated PR lists (~10→12 failed-check; 3→4 auto-merge armed)

Codex P2 review: line 29 said '~10 with failed required checks' but enumerated 12 PRs; line 30 said '3 with auto-merge already armed' but enumerated 4. Updated to match enumerated lists. Copilot table-format threads (line 2 / line 25) verified false-positive per known table-double-pipe FP class (.claude/rules/blocked-green-ci-investigate-threads.md) — direct awk inspection confirms single-pipe table rows.
