The spec/ Lean semantic master had no conformance gate, no codegen, and
no CI tie to implementations — alignment was carried entirely by human
review, the same mechanism that carries the ADRs. In practice the ADRs
plus greppable code comments were already the load-bearing artifacts,
so spec/ was the most expensive kind of stale documentation.
- delete spec/ and the spec-check CI workflow
- README: constitution rewritten around ADRs as decision truth
- AGENTS.md/CLAUDE.md: discipline re-anchored (new decisions -> new ADR,
never rewrite ADR history; supersede instead)
- code comments: re-anchor 'Mirrors Spec.X' invariants to ADR numbers
(cph-diag, cph-check, cph-model, hub runner/capacity/org, prisma)
- leave ADR bodies and .scratch audit snapshots untouched (history);
fix live references in open readiness tickets
- Add buildOutboundPayload: detect markdown format, isolate code blocks,
force plain text for tables, fallback from post to text on API rejection
- Add addReaction/removeReaction for processing status lifecycle
- Replace THUMBSUP with Typing→(remove on success | CrossMark on failure)
- Add unit tests for markdown rendering (15) and reactions (6)
