doctrine(autonomous-loop): rediscoverable-from-main invariant — meta-property the every-tick checklist serves (2026-04-30) by AceHack · Pull Request #969 · Lucent-Financial-Group/Zeta

AceHack · 2026-04-30T23:10:25Z

Summary

Adds an "Invariant — rediscoverable from `main` alone" section to docs/AUTONOMOUS-LOOP.md, framing the every-tick checklist as a mechanism serving an invariant rather than the invariant itself.

Verbatim direction from the maintainer

"Six-step tick close (docs/AUTONOMOUS-LOOP.md) has a satisfying property that should be an invariant for all future changes to this file"

follow-up sharpening: "not six step the rediscoverable on main part"

What's in scope

New "Invariant" section before "The every-tick checklist"
Names the load-bearing property: a fresh agent reading main alone can pick up the next tick
Names four supporting properties (tick-history on main, PR queue on host, substrate precedes narration, cron-as-cadence-engine)
Explicit test for future revisions: does the change preserve or strengthen the invariant?
Verbatim quote from the maintainer at the end of the section

What's NOT in scope

The every-tick checklist itself is unchanged. The point is exactly that the count of steps is incidental — only the discoverability is load-bearing. Future revisions can restructure provided the invariant holds.
No memory file added; the invariant lives in the doc itself, where the maintainer asked it to live.

Composes with

Otto-363 substrate-or-it-didn't-happen
non-durable-means-does-not-exist (the maintainer, 2026-04-30)
Together: "if it isn't on main, the next tick won't see it" — the structural reason the invariant matters.

Test plan

markdownlint passes on the changed file
Section placement verified (before "## The every-tick checklist")
Role-ref discipline honored (the maintainer's quote uses "the human maintainer" framing in surrounding prose; the verbatim quote retains the directive content)
No checklist content changed — surgical addition only

Pull request overview

Adds an explicit “rediscoverable from main alone” invariant to docs/AUTONOMOUS-LOOP.md, reframing the every-tick checklist as a mechanism that serves a cold-start continuity property for future sessions/agents.

Changes:

Add a new “Invariant — rediscoverable from main alone” section before the every-tick checklist.
Describe four supporting properties (tick-history shards, host-visible PR queue, substrate-first discipline, cron cadence independence).
Add a quoted maintainer directive anchoring the invariant.

…nt + #936 stale-PR fix (#970) 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.

…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. Co-authored-by: Claude Opus 4.7 <noreply@anthropic.com>

…g future tick-times — surface for maintainer decision before mass-fixing col1 (#973) 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>

…catch col1 schema violations at write-time, not 2 days later via PR review (#975) Per the structural-fix-beats-process-discipline pattern (Otto-341) + the rediscoverable-from-main invariant landed in PR #969: the check that catches col1 drift at write-time is the mechanism that preserves schema uniformity on main. What this checks: 1. Filename matches HHMMZ.md or HHMMSSZ-<hash>.md per the schema in docs/hygiene-history/ticks/README.md. 2. First non-empty line is a 6-column markdown table row starting with `| YYYY-MM-DDTHH:MM(:SS)?Z |` — exactly the ISO timestamp, no parenthetical, no extra prose. (Both with-seconds and no-seconds forms are valid ISO-8601; the schema doesn't pick a side.) 3. The col1 timestamp's date + HH:MM matches the filename's path date and HHMM. What this does NOT check: - Body content (cols 4-6) — intentionally free-form prose - The prefab pattern (col1 timestamp ≫ commit-author time) — requires git-log access not available pre-push for the current commit; deferred per the memory file linked in the script header Current-state on main: ~5 historical shards from April 28 violate this check. Those 5 are also implicated in the prefab-shard finding (memory/feedback_tick_history_prefab*), so fixing col1 mechanically would launder the body-level prefab claim. The check therefore lands in DORMANT mode — not yet wired into CI/pre-push. A future cleanup PR resolves the prefab-vs-schema decision before the check goes binding. Composes with B-0114 sub-item 1 (pre-push lint hook) — when that lands, this check joins the pre-push run. Co-authored-by: Claude Opus 4.7 <noreply@anthropic.com>

…bearing meta-property the every-tick checklist serves (the maintainer 2026-04-30) Adds an "Invariant — rediscoverable from `main` alone" section before the every-tick checklist. The maintainer 2026-04-30 sharpened my insight: not the six-step count, but the rediscoverable-on-main part is what should be an invariant for all future changes to this file. The added section names: - The invariant itself (a fresh agent reading main alone can pick up the next tick) - The four properties that make it true today (tick-history on main, PR queue on host, substrate precedes narration, cron-as-cadence-engine-not-session-memory) - The future-changes test (does the change preserve or strengthen the invariant?) The every-tick checklist remains as-is; this section explicitly frames the checklist as A mechanism serving the invariant rather than the invariant itself. Future revisions may restructure the checklist provided the rediscoverable property is preserved. Composes with substrate-or-it-didn't-happen (Otto-363) + non-durable-means-does-not-exist (the maintainer, 2026-04-30) which together establish "if it isn't on main, the next tick won't see it" — the invariant's structural reason.

Four fixes: 1. HHMMz.md → HHMMZ.md (case consistency with rest of file + README) 2. minimised → minimized (US English, matches surrounding text) 3. Cron bullet rephrased — 'fires regardless of which session is active' was misleading per session-scoped task semantics; reframed to 'fires whenever a session is active to receive it' + cross-ref to Session-restart recovery section 4. Verbatim-quote claim resolved — added paraphrase note + preserved the bracketed gloss with explicit '(paraphrased)' framing for honest attribution Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

…(6 fixes + 6 resolutions) (#992) Per autonomous-loop tick-must-never-stop discipline. Closing tick early per 'long conversation incoming' signal from maintainer. Co-authored-by: Claude Opus 4.7 <noreply@anthropic.com>
