ReleasePort's take

Light signal
editorial:auto 12d

The pipeline stop command was relocated to chameleon_mcp/stop/, and several legacy idiom markdown writer functions were removed.

Why it matters: Moving the stop pipeline changes location handling; removing dead writers eliminates unused code paths. Operators should update scripts referencing the old directory or functions before deploying v3.3.0.

Summary

AI summary

Full changelog

Changed

  • The Stop pipeline now lives in chameleon_mcp/stop/ (advisories, gates,
    pipeline with per-root RootContext); hook_helper keeps the same entry point
    and seams. Behavior-preserving: no output or decision changes.
  • Archetype renames now rewrite the idiom store, so renamed archetypes keep
    scoping idioms and survive view regeneration.
  • A v3 teammate's deprecation made via idioms.md is folded into the store
    (reactivation via the view stays refused; use /chameleon-teach).
  • Idiom store records are read through the hardened profile-artifact path
    (symlink-refusing, size-capped).
  • Teach and trust envelopes report idioms_migrated / idioms_quarantined
    when their call triggered the one-time store migration.

Removed

  • The dead legacy idiom markdown writers (_transition_slug_to_deprecated,
    _write_new_deprecated_idiom, _find_all_slug_sections,
    _render_idiom_block); the store owns all idiom writes.

Breaking Changes

  • The Stop pipeline moved from its original location to `chameleon_mcp/stop/`.
  • Removed legacy idiom markdown writer functions: `_transition_slug_to_deprecated`, `_write_new_deprecated_idiom`, `_find_all_slug_sections`, `_render_idiom_block`.
