odd: P1.3.1 closeout ledger + P1.3.2 gate forward handoff#119
Merged
Conversation
…ndoff Closeout artifacts for the 2026-04-19T21:21Z–2026-04-20T00:59Z session that landed P1.3.1 (oddkit_challenge governance_source + peer governance_uris, shipped as klappy/oddkit#116 + #117, 0.19.0 in prod). New files: - odd/ledger/2026-04-20-p1-3-1-challenge-canary-landed.md: full session retrospective with the D4 decision-pivot rationale, validator external-corroboration pattern, and the three-recurrence evidence for the contract-governs-handoff-drift canon principle (now standing). - odd/handoffs/2026-04-21-p1-3-2-gate-canary.md: forward handoff pointing the next session at P1.3.2 — gate's vodka anti-pattern refactor, two-phase scope (canon-first klappy.dev PR, then oddkit code PR). Frontmatter updates: - odd/handoffs/2026-04-20-p1-3-challenge-canary.md: status active → superseded, with superseded_by pointer to the new P1.3.2 handoff. Not in this PR (carry-forward): - P1.2 handoff 'bundled baseline' → 'minimal fallback' correction - P1.3 handoff three discover* → fetch* name corrections - canon/principles/contract-governs-handoff-drift.md draft All three deferred to bundle into a single small canon PR in a subsequent session per P1.3.2 handoff's O-open items.

Ledger at odd/ledger/2026-04-20-p1-3-2-gate-canary-landed.md captures the 2026-04-20T01:21Z-03:20Z session that shipped oddkit 0.20.0. Mirrors the P1.3.1 ledger structure (Summary, What Shipped, What the Validator Actually Checked, Patterns, Cleared, O-opens, Session Mechanics, Handoff, Provenance). Two handoffs flipped to status: superseded with superseded_by pointing at the new ledger: - odd/handoffs/2026-04-21-p1-3-2-gate-canary — the original two-phase handoff, superseded by the full P1.3.2 ship. - odd/handoffs/2026-04-20-p1-3-2-phase-2-gate-code-refactor — the mid-session Phase 2 forward handoff, superseded on arrival when Phase 2 shipped in the same session. Left in canon as documentation of the 'same-session handoff anti-pattern' called out in the ledger. Honest accounting in the ledger of the tradeoff between this session's smoke-heavy attestation (9 runs + live self-call) and P1.3.1's Sonnet 4.6 5-corroboration validator pattern. Neither is strictly superior; they catch different classes of issue. Refs klappy/oddkit#118 (merged 260492c), #119 (promotion 1308245), #120 #121 #122.

Low Risk
Documentation-only changes (new handoff/ledger markdown and a frontmatter status update) with no runtime or production impact.
Overview
Adds a new P1.3.1 closeout ledger (
odd/ledger/2026-04-20-p1-3-1-challenge-canary-landed.md) documenting the shippedoddkit_challengegovernance_source/governance_uriscanary and validation results.Introduces the forward handoff for P1.3.2 (
odd/handoffs/2026-04-21-p1-3-2-gate-canary.md) outlining the next canary work onoddkit_gate(canon-driven refactor + envelope updates), and marks the prior P1.3 handoff as superseded via frontmatter (status+superseded_by).Reviewed by Cursor Bugbot for commit 4544edd.
