Handoff

Production state: https://oddkit.klappy.dev/health returns {"version":"0.17.0"}. Envelope smoke 24 / 24 pass against https://oddkit.klappy.dev/mcp. No regressions.

• O-open P1 (frontmatter schema gap for status / superseded_by / governs / session_span) — closed by #116.
• P2.1 (backfill [Unreleased] and cut 0.17.0) — closed by #112 and #113.

• P1.2 — oddkit_encode batch-mode input + prompt-over-code canary refactor. See klappy://odd/handoffs/2026-04-20-p1-2-encode-canary for the full scope, gauntlet requirements, and smoke additions. Unblocked; prerequisites satisfied (DOLCHEO canon merged, schema covers the fields).
• P1.3 — The post-canary-refactor sweep (challenge → gate → preflight → validate → orient → search → catalog → cleanup → version). Same canary template as telemetry_policy and the forthcoming encode refactor. One PR per tool. ~8–10 more PRs over several sessions.
• P2.2 — Render CHANGELOG.md on klappy.dev at /oddkit/changelog and add version_notes_url to the MCP initialize response. Low priority; slot in when tool envelopes are being touched anyway.
• P3 — Carried forward: canon/principles/teams-over-swarms.md (tier 2), canon/patterns/bugbot-as-validator.md (tier 2, lower priority, may be subsumed into teams-over-swarms), canon/principles/mechanical-work-belongs-in-code.md (tier 2, first concrete application is P1.2).

Paste this into a fresh session to boot cleanly:

Resume P1.2 per klappy://odd/handoffs/2026-04-20-p1-2-encode-canary.

Current state: 0.17.0 in prod (oddkit.klappy.dev), frontmatter schema
extended (klappy.dev #116 merged), validator arc from the prior session
formally closed (odd/ledger/2026-04-19-validator-closeout-and-0.17.0).

Fetch the P1.2 handoff, run the gauntlet on the DOLCHEO canon reference
if not already done (check klappy://canon/definitions/dolcheo-vocabulary),
then apply the encode refactor locally (orchestrator applies, Sonnet 4.6
validates — path 3, do not dispatch Opus 4.7 execution agents to oddkit).

Credentials are in project instructions. Don't over-scope — P1.2 alone is
one session's work.

All the operating notes from the prior handoff still apply — read them in odd/handoffs/2026-04-20-fresh-session-continuation.md (now superseded but still the authoritative reference for rhythm, path 3 constraint, githook behavior, CF auto-deploy pattern, and managed-agent dispatch). This handoff does not repeat that content; it points forward.

Two additions worth carrying into the next session:

• Smoke script URL contract: ODDKIT_URL must include the /mcp suffix. Passing a bare origin hits the site 404 page and the smoke errors with "No data payload." The script's header comment documents this (ODDKIT_URL=https://preview-xxx.oddkit.klappy.dev/mcp).
• Default to parallel PR execution. When two PRs are independent (different repos, no shared gate), draft and push both before polling either. Serial polling is a bottleneck-respect violation. Lesson from this session: the initial instinct was to wait for Bugbot on #116 before starting #112 work; operator corrected it and the two ran concurrently.

• Prior fresh-session-continuation handoff: odd/handoffs/2026-04-20-fresh-session-continuation.md — superseded by this document.
• Session ledger for the closeout: odd/ledger/2026-04-19-validator-closeout-and-0.17.0.md — retrospective record, full timeline, decisions / observations / learnings / constraints / open items.
• Validator report reference: The Sonnet 4.6 validator session sesn_011CaDUFMF2HZ95s4t74oMmj under agent agent_011CaDUFJYJ6W3ZPE9DrZ4Ha produced the VERIFIED disposition that enabled the closeout. Event log persisted in the orchestrator's ephemeral filesystem at /home/claude/work/validator-events.json for this session's use; not committed to the repo as the report is now summarized in the ledger above.
