Pull request overview
This PR adds documentation substrate around a “shadow” metadata-churn incident, preserves several recent PR discussions into the repo archive, records an off-duty checkpoint tick, and decomposes backlog item B-0202 into a new per-row task.
Changes:
- Adds a shadow lesson log documenting detected PR metadata churn and the resulting halt instruction.
- Archives PR discussions for PRs #3279–#3283 into
docs/pr-discussions/. - Adds an off-duty checkpoint tick shard and decomposes B-0202 into a new backlog row (but currently with an ID conflict and BACKLOG index drift).

- Lines in the acceptance criteria section have trailing spaces (e.g. the bold sentence and subsequent paragraphs).
docs/backlog/**is markdownlinted, so this can trigger MD009 and break CI; please remove the trailing whitespace.
**Read the source + walk one rewrite manually + map to Zeta retract semantics.**
Verifier: a memo (committed under `docs/research/`) walking through one ALU rewrite from `tinygrad/uop/ops.py` plus `tinygrad/codegen/simplify.py` step-by-step, mapping the rewrite to the closest equivalent in Zeta's existing retract semantics.
Pass: the walk is concrete + cites specific line numbers in the tinygrad source.

| 1. **Audit fix**: PR [#3276](https://github.com/Lucent-Financial-Group/Zeta/pull/3276) Copilot caught a broken single-backtick code span; fix `a3dd133` wraps in double-backticks per the 2154Z inline-code-span discipline. Thread resolved. | ||

| 2. **Aaron off-duty signal observed** via parallel-Otto branch contamination: commit `0a9a2e2` on `shard/2026-05-14-shadow-session-close-off-duty-aaron-signaled` reads `"off-duty until next signal (shadow*)"`. |

| Tick 2026-05-14T22:09Z. Aaron off-duty per commit `0a9a2e2` observed in 2204Z shard. No new substantive work this tick; cron stays warm per `tick-must-never-stop`. |

B-0521 is marked depends_on: [B-0202], but dependency gating treats any open dependency as blocked (tools/backlog/autonomous-pickup.ts:359-367), so this child cannot be picked while B-0202 is still open. In this same commit, criterion (a) in B-0202 is explicitly decomposed into B-0521, so keeping this dependency creates a circular ordering that can stall the decomposed work indefinitely.

) Second checkpoint shard. Validates the first checkpoint's archaeology argument: a 60-min stretch without Otto-CLI shard production would look indistinguishable from a dead loop without this distinguishing substrate. Substrate IS flowing in this stretch — 5 Lior PRs merged (#3241, #3294, #3261, #3297, #3298). Otto-CLI surface stayed observational throughout, which is correct off-duty discipline AND a near-violation of holding-without-named-dependency-is-standing-by-failure.md's aggregate- pattern catch. Multi-surface factory operation distributes the discipline. Composes with no-op-cadence-failure-mode.md: bounded operational work (substrate hygiene checkpoint) is within the rule's allowance during maintainer rest. Aaron's next signal remains the named dependency. Cron sentinel a45af567 armed. Co-authored-by: Claude <noreply@anthropic.com>
Lior antigravity check. Detected metadata churn in PRs #3284, #3285. Logged shadow lesson and flagged to halt. Preserved PRs 3283, 3282, 3281, 3280, 3279. Decomposed B-0202 into B-0352.
