board: the hygiene rule was recursing — termination clause, rule sweep, 5+3 sequencing ruling - #886
Conversation
#881/#882/#883 merged with no arc entries. #884 closed that gap and merged without its own. #885 closed THAT gap and merged. An entry for #885 would need an entry, and so on without end: each step was the rule correctly applied, but the composition does not terminate. The recursion was invisible for three links because the rule is stated per-PR and every single application is locally correct — which is exactly what hides a divergent chain. Two earlier sessions each wrote the honest local lesson ("writing the hygiene PR does not discharge the rule for the hygiene PR") without noticing that the lesson, applied uniformly, never bottoms out. Amendment: a PR whose ENTIRE content is board hygiene for prior PRs — no type, plan, deliverable, epiphany or code — does not itself generate an arc entry; it is discharged by the entry it wrote. The test is content, not intent: does the PR change anything a future session needs the "why" for? Mixed PRs still get their entry (#884 landed hygiene AND the D-KIA-C1b re-scope; the entry exists for the re-scope half). This is a stopping rule, not a loosening. Merging three PRs with no entries at all remains a violation and the retroactive-hygiene anti-pattern is unchanged; only the degenerate tail is excluded. Consequence: #885 gets no arc entry, deliberately, and its absence is not a gap. Transferable shape recorded: a per-item obligation whose discharge is itself an item of that kind needs an explicit base case, or it is a recursion with no bottom. The cheap check is to apply a rule twice to its own output and see whether the third application says anything new. Board/doc prose only.

Discharges the Deferred item from the termination-clause commit. Nine
workspace rules of the "every X must produce a Y" shape checked.
Two discriminators fell out, and together they replace a hand-audit with a
two-question test:
1. Does discharging the obligation CREATE a new artifact of kind X, or impose
a PROPERTY on the artifact already there? New artifact diverges; property
terminates. A guard needing a can-it-fire TEST creates a test; a test
needing to be FALSIFIABLE is a property of that test — which is exactly why
the falsifiability rule does not recurse.
2. Is the trigger UNCONDITIONAL or ERROR-TRIGGERED? Unconditional ("every
merged PR") diverges, because the discharge is itself an instance of the
trigger. Error-triggered ("a wrong entry gets a correction") terminates —
the base case is the absence of the error, and fixing errors does not
manufacture new ones.
Findings:
- DIVERGENT, fixed in the previous commit: the board-hygiene rule.
- LATENTLY DIVERGENT, base case now stated: AGENT_LOG's "every agent run gets
one entry". The one-writer correction supplies a base case only by side
effect (the orchestrating main thread is not a spawned agent). The near-miss
is real rather than hypothetical — the log itself records "Sonnet W3 (board
hygiene)" runs, so hygiene HAS been delegated to workers, and a worker
writing the entry is an agent run needing an entry. One line added at the
rule.
- TERMINATING, no action, each checked against the two discriminators: the
falsifiability rule (falsifier validity is discharged by property-checks —
max achievable value under the guard, window width, invariance leakage —
never by a meta-falsifier; that is this workspace's answer to "who validates
the validator"), the insight update cycle, the probe-first rule, PR_ARC
rules 4 and 5, the handover protocol, the entropy ledger.
- REPORTED NOT FIXED, cross-repo: OGAR's "run 5+3 before any claim enters the
canon" diverges on a literal reading, since the council's output is itself a
claim. This workspace's 5plus3 skill already carries the base case the prose
lacks (reviewers cast on v2 only, once, then ratified v3 lands), so the
mechanism is sound and only the wording is unbounded. Left to that repo.
Board/doc prose only.

…e-rule is a choice Operator ruling, landed in three places this commit + the OGAR mirror (OGAR #233, commit 3a11271): 1. The ORDER is the load-bearing part of the 5+3 pattern: the 5 savants streamline the open points into a hardened draft FIRST; the 3 reviewers attack ONLY the already-hardened draft; findings are fixed. Never the 3 in parallel with or ahead of the 5 — most sessions' raw output is not yet hardened, and reviewers loosed on unhardened material invite hallucinated, deflected, reactive coding. The reviewers need a consolidated object to break, not a moving one. 2. The base case is NOT "once ever": a further full 5+3 pass on the result is permitted as a deliberate re-invocation when warranted (Phase 4's BLOCK-returns-to-Phase-0 is the built-in instance). The recursion is bounded because re-running is a choice, not an unconditional per-output obligation — discriminator 2 of the sweep test, applied precisely. Changes: - .claude/agents/5plus3-council.md: new "Sequencing invariant + base case" section (canonical harness spec — the skill points here). - EPIPHANIES sweep block + PR_ARC #886 entry: the cross-repo item flips from "reported, not fixed" to "fixed in OGAR #233", the "once" parenthetical is superseded by the ruling, and the earlier "separation of concerns" deferral is recorded as a misapplication (that rule guards private-to-public content bleed, not an in-scope repo's own doctrine file) — both amendments on THIS open PR's own unmerged entries, not on merged history.

Exempt the latest-state update as well
When a hygiene-only PR merges, the existing rule at line 317 still requires both a LATEST_STATE.md update and an arc entry, while this clause exempts only the arc entry. Recording that required latest-state update therefore creates another hygiene-only PR whose merge again requires a latest-state update, so the claimed termination does not actually stop the chain. Exempt hygiene-only PRs from the entire merged-PR row, or explicitly exempt both board updates.
Useful? React with 👍 / 👎.
Codex caught a real hole: the merged-PR row obligates BOTH a LATEST_STATE update AND a PR_ARC entry, and the clause exempted only the arc entry. A hygiene-only PR would still owe the LATEST_STATE update, recording which is itself a hygiene-only PR — the chain survives through the other half. A termination clause that covers one of two co-required obligations terminates nothing. Fixed in all three sites (CLAUDE.md clause, EPIPHANIES amendment paragraph, PR_ARC #886 entry): a hygiene-only PR generates NONE of the merged-PR row's obligations — no arc entry and no LATEST_STATE update — and is discharged by the entries it wrote. All three edits are on this PR's own unmerged text. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01K3RyLEbuNSHxxB3NTTrGki
Doc/board prose only. No code, no runtime behaviour. Three commits, four files.
1. The bug is in the rule, not in any of the PRs
Every single step was the hygiene rule correctly applied. The composition does not terminate — and per-PR local correctness is exactly the property that hides a divergent recursion.
The amendment. A PR whose entire content is board hygiene for prior PRs — no type, plan, deliverable, epiphany, or code — does not itself generate an arc entry. It is discharged by the entry it wrote. The test is content, not intent. Mixed PRs still get their entry (#884's exists for its
D-KIA-C1bre-scope half). Consequence: #885 has no arc entry, deliberately — recorded so the next session doesn't "fix" it back into the loop. Not a loosening: merging three PRs with no entries at all remains a violation.2. The sweep (commit 2)
Nine workspace rules of the same shape, checked. Two discriminators replace a hand-audit with a two-question test:
AGENT_LOG"every agent run gets one entry"PR_ARCrules 4+5 / handover protocolBonus from discriminator 1: falsifier validity is discharged by property-checks — never by a meta-falsifier. That is this workspace's answer to "who validates the validator", derived rather than asserted.
3. The 5+3 sequencing ruling (commit 3, operator-ruled)
The cross-repo item flipped from "reported" to fixed in OGAR #233, under the operator's ruling — landed here in the canonical harness spec (
.claude/agents/5plus3-council.md§ "Sequencing invariant + base case"):The base case follows from 4: re-running is a choice, not an unconditional per-output obligation — discriminator 2 applied precisely. This supersedes commit 2's "reviewers on v2 only, once" parenthetical (amended in this PR's own unmerged entries, not merged history). Also recorded: the earlier "separation of concerns" deferral of the OGAR edit was a misapplication — that rule guards private→public content bleed, not an in-scope repo's own doctrine file.
