feat: spec-change loopback — SDD 'change spec -> regenerate affected code'
Operationalises framework §5.1 for an existing feature. Same pipeline (driver unchanged);
stations become amend-aware; tests are the change-propagation layer.
- core/req-delta.ts reqDelta(old,new) -> {added,changed,removed} REQ-ids (TDD); cli/req-delta.
- spec-to-tests (amend): per req-delta — added -> new .skip'd; changed -> edit test + RE-SKIP
(keeps main green until code catches up); removed -> delete test. On the spec PR.
- implement (amend): un-skip new+changed tests, update code, remove dead code for removed REQs.
- verify-unskip is PR-type-aware (core/unskip.isSpecBranch): no-op on devloop/spec/* (spec-to-tests
is the legit author there; vitest/trace/mutation + spec-review keep it honest), enforces
unskip-only on devloop/<slug> (the implement seam). template passes the PR head branch.
- specify (amend existing spec, stable REQ ids); loop skill (spec PR on devloop/spec/<slug>).
- design doc docs/2026-06-21-spec-change-loopback-design.md; USAGE section. driver state machine
unchanged. v0.4.0, 146 tests green.
