promote: main → prod (0.18.0 — encode DOLCHEO + governance_source)

[klappy]

Promote 0.18.0 to prod. Encode retrofitted to declare governance_source + DOLCHEO batch-prefix input. Merged to main at 290dde5. Main-preview smoke 61/61 pass. All ship-critical checks green on #114. Sonnet 4.6 validator VERIFIED (11/11, 3 non-blocking advisories).

What's in this promotion

• feat(encode): DOLCHEO batch prefix + governance_source envelope (0.18.0) #114 — feat(encode): DOLCHEO batch prefix + governance_source envelope (0.18.0)
  • Paragraph-prefix batch input: [D] / [O] / [L] / [C] / [H] / [E] / [O-open P1] / [O-open P2.1]
  • facet: "open" and priority_band on artifacts from [O-open ...]
  • governance_source + governance_uri in encode envelope (two-tier: knowledge_base | minimal)
  • Minimal fallback upgraded from 5-letter OLDC+H to 6-letter DOLCHEO
  • Letter dedup in discovery (canon's observation.md + open.md both claim O)
  • Tool description rewritten to reference DOLCHEO + [...] syntax
  • 0.17.0 release-note correction (challenge + encode were silent at HEAD despite the CHANGELOG claim; this release retrofits encode; challenge is tracked for P1.3)
  • Known limitation: getIndex lacks skipBaselineFallback, so encode's knowledge_base_url override doesn't strict-fall to minimal (P1.3 follow-up)

Evidence

• Branch-preview smoke: 61/61 (pre-merge on encode-batch-mode-and-canary-refactor-oddkit.klappy.workers.dev/mcp)
• Main-preview smoke: 61/61 (post-merge on main-oddkit.klappy.workers.dev/mcp at 0.18.0)
• Sonnet 4.6 read-only validator: VERIFIED, 11/11 checks, evidence externally corroborated
• Parser tests: 105/105
• Typecheck: clean

Note

Medium Risk
Changes oddkit_encode request parsing and response shape (new governance_source, governance_uri, and optional facet/priority_band fields), which may affect downstream consumers despite aiming for backward compatibility.

Overview
Updates oddkit_encode to support DOLCHEO paragraph-prefix batch input ([D], [O], [L], [C], [H], [E], and [O-open P1]/[O-open P2.1]), emitting one artifact per paragraph and preserving Open items via facet: "open" and optional priority_band.

Encode now returns governance provenance in its result (governance_source: knowledge_base|minimal plus governance_uri), upgrades the minimal fallback vocabulary to include E, and deduplicates discovered encoding-type docs by letter (handling canon docs that both claim O). Adds end-to-end smoke coverage for the new encode envelope/batch behavior, updates the encode tool description, bumps versions to 0.18.0, and documents the release in CHANGELOG.md.
