Step 12 of v3.4.1 plan. Surgical line-by-line generalization of references
to the ultra-cc-architect plugin (no longer publicly distributed):
- CLAUDE.md: 8 hits → "opt-in upstream architect plugin (not bundled)"
- README.md: 9 hits including bare slug at line 646 (removed entirely);
rephrased to "no longer publicly distributed" with the architecture/
filesystem slot still supported by /ultraplan-local
- SECURITY.md: 1 hit → generalized "Opt-in upstream architect step"
CHANGELOG.md historical references preserved per brief; appended a
2026-05-04 note at top of [3.0.0] block stating the plugin is no longer
publicly distributed but the architecture/overview.md slot remains
supported for any compatible producer.
The architecture/overview.md filesystem contract (Handover 3, EXTERNAL,
drift-WARN) is unchanged — anyone implementing a compatible producer
can plug in.
361 tests still green (no regressions). doc-consistency pins for
/ultracontinue-local and Handover 7 § Lifecycle still pass.
