Closes #1798

What

  • Regenerated fixtures/odd-routing-canonical.md from gentle-ai 4213c71a (PR gentle-ai#5250) with scripts/mirror-odd-routing.mjs (offline).
  • Moved the ratchet anchors in tests/odd-routing-canonical-ratchet.test.ts to the new canonical wording: the writer trigger row is now two anchors (named reason; never for size, a large task alone, file count, or a price ratio), and the stale "Gentle Shell leads the canon" comments are gone.
  • Marked G1 (canon parity) done in odd/tasks/delegate-for-reason.md.

No Pi asset text changed: the ratchet found no mismatch on the Pi side.

Checks

  • RED: after regeneration the ratchet failed 1/7 ("canonical fixture dropped anchor: writer trigger fires only for a large task").
  • GREEN: ratchet 7/7.
  • npm test: all stages pass (4914 tests, 0 fail).
  • node scripts/build-runtime-modules.mjs --check: runtime matches sources.

Risk: low (test fixture and anchors only; no runtime behavior).

Summary by CodeRabbit

  • Documentation
    • Clarified routing, testing, risk, and delegation guidance, including when to delegate work and how to coordinate parallel edits.
    • Updated task-sizing guidance for persisted-format changes and uncertainty.
    • Clarified long-session guidance to pause around 150k parent-context tokens and delegate the next bounded unit.
  • Tests
    • Updated guidance checks for delegation triggers and long-session limits.

Regenerate fixtures/odd-routing-canonical.md from gentle-ai 4213c71a and move the ratchet anchors to the new canonical wording: the writer trigger now fires only for a named reason, so the rows that marked Gentle Shell as leading the canon are aligned with it.

Closes #1798

📝 Walkthrough

Walkthrough

The canonical ODD routing fixture and ratchet anchors now reflect updated testing, risk, delegation, and long-session guidance. The related parity task is marked complete.

Changes

Canonical ODD routing mirror

Layer / File(s) Summary
Update routing guidance and ratchet
fixtures/odd-routing-canonical.md, tests/odd-routing-canonical-ratchet.test.ts, odd/tasks/delegate-for-reason.md
The fixture adds testing, verification, risk, and delegation requirements. Ratchet anchors specify named-reason writer delegation and a long-session backstop at approximately 150k parent-context tokens. The parity task records completion and the re-mirror anchors.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 9faa7

The test gap should be fixed, and the canonical fixture should be verified against the requested upstream source before merge.

Add a broad DELEGATION price-ratio assertion to T24/L49.

T24/L49 states that a price ratio must not fire the Writer rule. The DELEGATION check rejects only two exact legacy phrases, so a differently worded price-ratio trigger can pass. The canonical mirror check also verifies only the size and file-count wording.

Suggested test
 	assert.doesNotMatch(writer, /about 3x|price ratio of|- \*\*Model routing\*\*/, "the writer module keeps the cost reason");
+	assert.doesNotMatch(delegationWriter, /ratio|price|Model routing|small path/i, "delegation Writer rule still fires on cost");
 	// T24 follow-up: no surface names the price ratio as a writer reason.
