…nt + #936 stale-PR fix

Single-tick row for the autonomous-loop heartbeat at
2026-04-30T23:12Z. Captures:

- Maintainer-directed invariant landing on docs/AUTONOMOUS-LOOP.md
  (#969) — sharpening prior tick's "six-step" insight to the
  load-bearing "rediscoverable on main" property
- Stale-PR triage on #936 (Alexa B-0114 row) — rebase onto
  main resolving BACKLOG.md, 4 review-thread fixes, force-
  push, batch-resolve

Per the autonomous-loop tick-must-never-stop discipline.

Pull request overview

Adds a single tick-history shard entry capturing the 2026-04-30T23:12Z autonomous-loop heartbeat, documenting the rediscoverable-from-main invariant framing and the #936 stale-PR triage outcomes.

Changes:

  • Added a new tick-history shard row for 2026-04-30T23:12Z.
  • Recorded the rediscoverable-from-main invariant update (via #969) and #936 stale-PR fixes/triage details.

P1: The third column is the cron-id / cron sentinel and is expected to be the 8-character job ID from CronList (see docs/hygiene-history/loop-tick-history.md schema). This row uses 04a4b8a (7 chars), which looks like a truncated value and breaks the documented format; please update it to the full 8-char cron ID from the tick’s CronList output.

…rds (#971)

Per docs/hygiene-history/ticks/README.md schema, the first
column of each shard MUST be exactly an ISO-8601 UTC timestamp.
15 shards (April 28, 29, 30) carried a parenthetical context
appended to the timestamp in col1 — pattern caught by Copilot
on PRs #745-755 + #970.

The parenthetical content is preserved by each shard's body
column (col4) which already restates the tick context. The
fix removes the col1 violation without losing information.

Surface drift fix per the just-landed rediscoverable-from-main
invariant on docs/AUTONOMOUS-LOOP.md (#969): tick-history is
one of the four properties that makes the invariant true. If
shards drift in format on main, future agents see two
incompatible patterns and have to guess. Schema-uniform shards
make the read surface predictable.

Files affected (15):
- docs/hygiene-history/ticks/2026/04/28/{0408,0418,0433,0501}Z.md
- docs/hygiene-history/ticks/2026/04/29/{0235,0240,0320,0350,0400,0425,0430,0435,0440}Z.md
- docs/hygiene-history/ticks/2026/04/30/{2018,2312}Z.md

No data loss — only col1 prose drift removed; body context
fully preserved. Trailing newline added on 3 files where it
was missing.
