…g future tick-times — surface for maintainer decision before mass-fixing col1 Codex P2 review on PR #740 caught a pattern across 14+ open tick-history shard PRs from 2026-04-29: col1 tick-times are 40-80 minutes ahead of the commits' author-times. The shards weren't recording past ticks — they were prefabricating shard files for future tick slots. Empirical sample: | PR | PR opened | Claimed tick | Commit author | Gap | |---|---|---|---|---| | #728 | 02:05:49Z | 02:45:00Z | 02:05:42Z | +40m | | #730 | 02:07:17Z | 02:55:00Z | 02:07:14Z | +48m | | #734 | 02:14:15Z | 03:15:00Z | 02:14:12Z | +61m | | #740 | 02:24:24Z | 03:45:00Z | 02:24:20Z | +81m | The prior-tick col1 cleanup (PR #971) on 15 shards already on main and the per-PR force-pushes on #745-755 + #968 fixed the schema-violating parenthetical, but the underlying prefabrication concern was buried under the more visible Copilot-P1 col1 finding. Two interpretations: 1. Mis-timestamped recording — agent computed col1 wrong 2. Intentional batch prefabrication of future-tick receipts Either way, mechanically fixing col1 on the remaining 14 PRs would launder the prefabrication: shards would look schema- compliant but still claim factually-incorrect tick times. Composes with the rediscoverable-from-main invariant landed in PR #969: tick-history-on-main is one of four supporting properties; false time-claims subvert the invariant. Decision options for the maintainer (in the file): - Close affected PRs (audit-trail integrity over evidence- density) - Rewrite col1 to commit-time - Add a note column for time-of-record vs time-of-event - Accept prefab pattern as intentional Filing this as substrate (per substrate-or-it-didn't-happen) and explicitly NOT mass-fixing col1 on those PRs until direction. MEMORY.md index entry added; latest-paired-edit marker updated. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Pull request overview
Adds a new memory feedback entry documenting an audit-trail integrity concern: multiple open tick-history shard PRs appear to claim future tick-times (col1) relative to commit author times, and records decision options before any mass schema cleanup could “launder” the timestamp claim.
Changes:
- Adds a new feedback memory file capturing the finding, evidence sample, interpretations, and maintainer decision options.
- Updates
memory/MEMORY.mdto (a) point to the new memory entry and (b) update the “latest-paired-edit” fast-path marker.

| description: 12+ open tick-history shard PRs from 2026-04-29 carry tick-time labels in col1 (e.g. 03:45Z) that are ~40-80 minutes ahead of their actual commit-time (e.g. 02:24Z). Codex P2 review on PR #740 caught this. Surfacing as substrate before mechanically fixing col1 schema on these PRs would launder fabricated liveness evidence onto main.

Summary
Files an audit-trail-integrity finding as substrate before mechanically extending the col1 cleanup pattern to the remaining 14 open tick-history PRs from 2026-04-29.
Codex P2 review on PR #740 caught that those shards' col1 tick-times are 40-80 minutes AHEAD of the commits' author-times. Either mis-timestamping or intentional batch prefabrication — either way, mass-fixing the col1 schema would launder the timestamp claim, making fabricated/mis-recorded liveness evidence look schema-compliant.
Affected PRs (14)

PRs #745, #746, #753, #754 + the 15 shards on main fixed via #971 / #968 / earlier per-PR force-pushes share the same body-level prefab pattern but the col1 strip already shipped — future cleanup may need to revisit those if the maintainer chooses option 2 or 3 below.Decision options (in the memory file)
Why this matters
Composes with the rediscoverable-from-
maininvariant just landed in PR #969 — tick-history-on-mainis one of four supporting properties. False time-claims subvert the invariant exactly the way schema drift does, just at the data layer instead of the format layer.What I am NOT doing
