Prod at 0.18.0, smoke 61/61. + +The session also ran into — and named — a failure mode that deserves canon attention. The P1.2 handoff described a three-tier cascade (`knowledge_base` → `bundled` → `minimal` → fail-loud). The governing contract (`canon/constraints/core-governance-baseline`) defines `"bundled"` as a build-time snapshot of files listed in the required-baseline MANIFEST, with encoding-types explicitly canon-only. The handoff's "bundled DOLCHEO minimum" was hardcoded constants — which the contract's enum calls `"minimal"`, not `"bundled"`. Word collision, not design conflict. The orchestrator surfaced this as a design tension at first, then recognized it as vocabulary drift once the contract was re-read. The same pattern recurred twice more in the session (scope framing of the work, missing the version bump) before the operator named the meta-pattern: the orchestrator treats the last document read as ground truth instead of grounding in code and contracts first. Fix: read the target code before framing scope; cite existing state before proposing delta. + +The validator's external corroboration carried weight. Sonnet 4.6 pulled the main branch's `orchestrate.ts` bytes to confirm zero `governance_source` references (verifying the 0.17.0 correction claim was accurate), cited the exact canon section (`core-governance-baseline §Canon-Only`) to confirm the two-tier decision, and verified letter dedup from a live response.

Main-preview also at 0.17.0. +- **[L]** The P1.2 handoff framed this as a "canary refactor" but encode was the original canary (PR #96, my first Opus 4.7 work). The code comment `"mirrors encode pattern from PR #96"` on `discoverChallengeTypes` was visible on the first grep and named encode as the original. Framing the work as "make encode governance-aware" was recency-as-authority — encode has been governance-aware since the Opus 4.7 essay work. + +### Planning (18:40–19:15Z) + +- **[D]** Two-tier cascade (`knowledge_base` → `minimal`), not three. Rationale: `core-governance-baseline` explicitly lists `odd/encoding-types/` as canon-only. The handoff's "bundled DOLCHEO minimum" is hardcoded constants, which maps to the contract's `"minimal"` enum, not `"bundled"`. Word collision, not design conflict. If canon-outage telemetry later shows harm, adding `"bundled"` as a third envelope value is additive and non-breaking. +- **[D]** Bundle the 0.17.0 → 0.18.0 version bump in the same PR as the feature work. Handoff explicitly allowed either pattern; in-PR keeps one atomic shippable unit (one validation, one rollback surface). MINOR because all changes are additive to the user-facing contract (new envelope fields, new input syntax, new optional artifact fields). +- **[D]** Scope the PR to encode only — no canon-principle-about-contract-vs-handoff-drift, no handoff-wording fix, no challenge `governance_source` retrofit. Those are separate PRs that can pick up naturally in subsequent sessions. Operator had explicitly named scope creep at session start. +- **[L]** The PRD step matters. Skipping directly from exploration-prose to code edits without writing a reviewable plan document caused the operator to flag a real pattern — over-meta when planning, under-specified when executing. Writing the PRD as a file (`/home/claude/work/ledger/2026-04-19-p1-2-prd.md`) forced articulation and gave the operator a scannable artifact for revision. +- **[C]** Before framing work, read the target code. Before echoing handoff vocabulary, cross-reference it against the governing contract. Before proposing scope, subtract what's already shipped from what the handoff describes and present only the delta. + +### Execution (19:15–20:00Z) + +- **[O]** Encode already reads vocabulary from canon at runtime via `discoverEncodingTypes` (PR #96's legacy). Filter for `encoding-type`-tagged docs in `encoding-types/`, parse Letter / Name / Trigger Words / Quality Criteria from each. Threading `knowledge_base_url` already in place. +- **[O]** `runEncodeAction` already returned `result.artifacts` as a per-artifact array. The "per-artifact output" half of P1.2 was partially shipped; the gap was prefix-tag parsing and the envelope fields. +- **[O]** `governance_source` was absent from `orchestrate.ts` at HEAD (confirmed: 0 references). The 0.17.0 CHANGELOG entry for "`governance_source` on refactored tool envelopes" claimed challenge, encode, and telemetry_policy all declared it. In practice only telemetry_policy did. +- **[D]** `discoverEncodingTypes` signature change: returns `{ types, source }` instead of `EncodingTypeDef[]`. Single caller (`runEncodeAction`) updated. Source cached alongside the existing cache key. +- **[D]** Prefix-tag grammar: `^\[([A-Z])(?:-(open))?(?:\s+(P\d+(?:\.\d+)?))?\]\s*`. Letter required, `-open` facet optional, priority band optional. Detection cascade: `isPrefixedBatchInput` → `isStructuredInput` (legacy TSV) → unstructured trigger-word fallback. +- **[D]** Letter dedup in discovery keeps the first match per letter. Canon now has both `observation.md` (closed) and `open.md` (facet=open) claiming letter `O`; the registry stays single-character-per-entry. +- **[O]** Typecheck surfaced one error: `debug.knowledge_base_url` type on `OddkitEnvelope` is `string | undefined`, not nullable. Fixed by dropping the `?? null` and passing `knowledgeBaseUrl` directly. Cached fix in mind: telemetry_policy's pattern ships `null` because it's in `index.ts` JSON-serializing outside the strict envelope type; orchestrate.ts enforces the type. +- **[O]** Parser tests 105/105 passed post-edit. Typecheck clean after the one fix. + +### Push and preview smoke (20:00–20:20Z) + +- **[O]** Branch pushed to origin.

Failure: strict-mode assertion on `knowledge_base_url` override expected `governance_source: "minimal"`, got `"knowledge_base"`. +- **[L]** The failure exposed an index-layer limitation the handoff didn't anticipate. `getIndex` merges baseline + canon entries by design (`arbitrateEntries`: canon overrides baseline, baseline is the floor). When override URL points at a non-canon repo (`github.com/torvalds/linux`), baseline's encoding-type docs still resolve — so `discoverEncodingTypes` correctly returns `knowledge_base`. Strict-mode at the index layer requires adding `skipBaselineFallback` to `getIndex`, paralleling what `getFile` already supports.

Bugbot returned neutral. +- **[H]** Sonnet 4.6 validator dispatched (agent `agent_011CaDj46VwmidBz5g3wMhdJ`, session `sesn_011CaDj48ax5VEXyMfxrDves`, environment `env_016RffZyqSdHeb5s3Z6UABw8`). Read-only MCP role to oddkit. 11-check validation protocol with required external evidence for each claim per `canon/principles/agent-self-report-under-stress`. +- **[L]** Environment variables must be exported for python3 subshells to read; inline `VAR=val python3 ...` with the var inside the python script's `os.environ` doesn't work on this shell. Recorded in the dispatch script as a fix. + +### Validator results + corroboration (20:45–21:00Z) + +- **[O]** Validator ran 30 bash tool calls + 3 oddkit MCP calls. Canon reads: `oddkit_orient` → `oddkit_get core-governance-baseline` → `oddkit_get dolcheo-vocabulary`. Bash corroborations included: clone branch, curl the branch-preview MCP endpoint against each of the 11 checks, grep main branch's `orchestrate.ts` bytes for `governance_source` references. +- **[O]** Verdict: **VERIFIED**. 11/11 checks passed. Three non-blocking advisories: `debug.duration_ms = 0` on cache-warm calls (valid per contract), governance list shows `O → Observation` only (per-spec since Open is a facet), challenge still lacks `governance_source` (acknowledged P1.3 follow-up). +- **[L]** The `agent-self-report-under-stress` principle earned its keep. The validator cited check 10's result: "Main `orchestrate.ts` (88,425 bytes fetched): **0 occurrences** of `governance_source` — PR's correction is accurate." That's external verification, not trust. Future validator dispatches should continue to require bytes-level corroboration on claims that reference external state. + +### Squash-merge, promotion, prod smoke (21:00–21:04Z) + +- **[O]** PR #114 squash-merged to main at `290dde5cbb1a86d22dff8b57b49d0bf65a761214`. +- **[O]** Main preview flipped to 0.18.0 after ~24s. Smoke 61/61 pass. +- **[H]** PR #115 opened (main → prod, merge-commit preferred by operator for promotions). +- **[O]** PR #115 required checks green. Bugbot in progress (but already returned neutral on #114 for the identical commit SHA). Merged. +- **[O]** Prod flipped to 0.18.0 after ~24s. First smoke run: 51 pass, 10 fail. Second: 58/3. Third–fifth: 61/61. +- **[L]** Isolate warmup flakiness on CF prod is a real pattern. First smoke run immediately after prod deploy can flake as different isolates serve 0.17.0 vs 0.18.0. Verified by direct curl showing correct prefix-parser behavior while the node smoke test was hitting a different isolate. Pattern matches the prior session's closeout O8: "Main preview transient DNS cache overflow on first post-merge smoke. Second call passed cleanly." +- **[D]** Accept 3 consecutive 61/61 smoke runs as the "prod clean" gate. Not arbitrary — it's the operational threshold that distinguishes transient warmup from a real regression. + +### Encodes + +- **[E]** Session PRD committed to `/home/claude/work/ledger/2026-04-19-p1-2-prd.md` as the executable plan artifact — structure, scope (in/out), contract, detection cascade, test plan, workflow. +- **[E]** Validator dispatch script at `/home/claude/work/dispatch-validator.sh` — reusable template for future Sonnet 4.6 read-only validation agents. Updated with the env-var-export fix. +- **[E]** This ledger committed to the codebase at `odd/ledger/2026-04-19-p1-2-encode-dolcheo-landed.md`. +- **[E]** Forward-pointing handoff committed at `odd/handoffs/2026-04-20-p1-3-challenge-canary.md`. +- **[E]** Prior post-closeout handoff (`odd/handoffs/2026-04-20-post-closeout`) marked superseded in the same PR. + +### Handoffs + +- **[H1]** Merges this session: + - `klappy/oddkit#114` → `290dde5` — feat(encode): DOLCHEO batch prefix + governance_source envelope (squash to main). + - `klappy/oddkit#115` → `e6dbba5` — main → prod promotion for 0.18.0 (merge commit). +- **[H2]** Production state: `https://oddkit.klappy.dev/health` reports `version: 0.18.0`. Prod envelope smoke 61/61 pass × 3 consecutive runs. +- **[H3]** Forward pointer: `klappy://odd/handoffs/2026-04-20-p1-3-challenge-canary` supersedes `klappy://odd/handoffs/2026-04-20-post-closeout`. +- **[H4]** Next work unit: P1.3.1 — retrofit `oddkit_challenge` envelope to declare `governance_source`. Same canary shape as encode, smaller delta (challenge already reads canon via `discoverChallengeTypes`). + +--- + +## Timeline + +| Time (UTC) | Event | +|---|---| +| 18:32 | Fresh session open.

Smaller delta: challenge already has `discoverChallengeTypes`, `discoverBasePrerequisites`, `discoverNormativeVocabulary`, `discoverStakesCalibration` threading canon at runtime. The gap is envelope-level declaration. One PR on klappy/oddkit, PATCH or MINOR bump (TBD in planning), path-3 workflow, Sonnet 4.6 validator. The sweep then continues through gate → preflight → validate → orient → search → catalog → cleanup → version (per the post-closeout handoff's priority order). + +- **[O-open P2]** **Encode index-layer strict-mode.** `getIndex` lacks `skipBaselineFallback`. Adding it would let encode honor strict overrides — when `knowledge_base_url` points at a repo without encoding-type docs, fall through to `"minimal"` rather than silently serving baseline entries via `arbitrateEntries`. Documented in 0.18.0 CHANGELOG Known Limitations. Natural to bundle with challenge's P1.3.1 refactor if challenge uses `getIndex` similarly; otherwise separate PR. + +- **[O-open P3]** **Handoff text correction on `klappy://odd/handoffs/2026-04-20-p1-2-encode-canary`.** The handoff's Tier 2 wording says "bundled baseline" where the contract's enum reserves `"bundled"` for MANIFEST-listed files. Rename to "minimal fallback" and Tier 3 to reflect that encode's cascade has no fail-loud tier (degrades gracefully). Tiny follow-up PR on klappy.dev. Low priority but worth closing the loop so future sessions reading that handoff don't hit the same word-collision. + +- **[O-open P4]** **Candidate canon principle — "Contracts govern handoffs when vocabulary drifts."** The recency-as-authority failure mode recurred three times this session (two-tier tension, scope framing, missing version bump). Each time the fix was to ground in code and canon, not in the latest handoff's words. If this pattern keeps recurring, a short principle (`canon/principles/contracts-govern-handoffs-drift.md`, tier 2) is worth writing. Watch for one more occurrence before committing to the doc — "Use Only What Hurts" says build when pain is acute, not before. + +- **[O-open P5]** **CHANGELOG render route on klappy.dev.** Carried forward from the prior session's handoff. Add `/oddkit/changelog` route, add `version_notes_url` to the MCP `initialize` response. Low priority; slot in when tool envelopes are being touched anyway — P1.3 sweep is the natural window. + +--- + +## How this ledger will be validated + +If a next-session reader opens this doc and the forward-pointing handoff and can start P1.3.1 without rereading transcripts or the P1.2 PR, the closeout succeeded. If the reader has to reconstruct what 0.18.0 shipped, which checks passed, or what the validator verified, this ledger failed — file a learning and revise.
