Tick shard for the 3h window 04:45Z-08:00Z. 15+ PRs landed plus PC-crash recovery midstream. Crash recovery empirically validated the cron-substrate continuity mechanism: committed substrate IS the recovery surface; no work loss because the last pre-crash commit had been pushed.

…ery + forwarded-conversation discipline

15+ PRs landed in the 3h window since the 04:45Z shard, plus a PC-
crash recovery midstream:

Pre-crash cluster: B-0191 final, B-0006 tier-49, B-0193 bootstrap-
razor row, knights/knaves preservation, B-0194 IncrementalAuto +
checkBilinear, src/Core/Units.fs (22 unit tests, 4 highest-pay UoM
declarations, derived-measure algebra), F# RFC pre-draft for
existential-quantification, B-0195 DBSP cross-check row, DBSP
Prop 3.5 verification (CONFIRMED counter-example, MISATTRIBUTED
paper citation), B-0197 Lean cleanup row.

Crash + recovery: cron lost, re-armed; git state clean; no work
loss because c836d6f had been pushed pre-crash.

Post-crash cluster: B-0196 BigInt + bignumber row (multiple reviewer
waves), B-0198 upstream-contribution row (absorb-and-contribute
discipline), B-0196 acceptance criterion (d) verification (F# UoM
does not natively extend to BigInteger).

Three Claude.ai conversations forwarded -- preserved verbatim where
directly authorized (knights/knaves PR #1588), held as chat-record
where the conversation itself flagged substrate-inflation risk
(topological-invariants + smooth-by-construction + DORA-as-map +
ARC-AGI-3 synthesis pieces). Goldfish-ontology check fired
correctly on ARC-AGI-3 (existing substrate at
memory/project_arc3_beat_humans_at_dora_in_production_capability_
stepdown_experiment_2026_04_22.md).

Crash recovery validated empirically: committed substrate IS the
continuity mechanism. Cron-substrate-continuity rule from
PR #1574 confirmed at infrastructure level.

Pull request overview

Adds the 2026-05-05T08:00Z hygiene-history tick shard documenting the 04:45Z–08:00Z window, including the pre-/post-crash PR cluster and the crash-recovery continuity validation.

Changes:

  • Introduces a new tick shard markdown file for 2026-05-05 0800Z.
  • Records chronological “what landed,” crash + recovery checklist, and load-bearing learnings.
  • Captures forwarded-conversation preservation notes and next-tick orientation.

…s path (#1598 reviewer)

Two reviewer findings addressed:

1. cron-mechanism-unreliable identifier was not verbatim from CLAUDE.md.
   Updated to quote the actual bullet title: "Tick must never stop --
   every-tick-verify because the cron mechanism is unreliable" (CLAUDE.md
   line 661+).

2. poll-pr-gate-batch.ts path missing tools/github/ prefix. Updated to
   bun tools/github/poll-pr-gate-batch.ts so the recovery checklist is
   directly actionable.

The schema-conformance reviewer thread (P1: shard should follow the
6-column-table-row first-line schema from docs/hygiene-history/ticks/
README.md) is held pending Aaron 2026-05-05 framing: "hygiene was a
pre-trajectory design ... they either compose or collapse together."
The schema may itself be deprecated by the trajectory-file pattern;
retrofitting a deprecated shape is the wrong move. Bootstrap-razor
(B-0193) examines the compose-vs-collapse question on schedule.

…P1 reviewer)

Per docs/hygiene-history/ticks/README.md schema: each shard requires a
6-column markdown table row as the first line (timestamp / model id /
cron sentinel / body / PR ref / observation).

Compose-not-collapse interpretation per Aaron 2026-05-05 framing: add
the table-row first line (projection-ready form) WHILE preserving the
heading + sections (substantive content). The two coexist: the
table-row feeds the legacy table read surface; the heading-sections
provide the rich-context narrative. Bootstrap-razor (B-0193) still
gets to decide compose-vs-collapse on its scheduled cadence; this
fix doesn't preempt that decision -- it just makes the shard
schema-compliant in the meantime.
