Chameleon

Field feedback: the turn-end Stop idiom self-review read as a recurring "hook
flood" — it re-fired in every new chat, and a docs-only turn (the
/chameleon-init CLAUDE.local.md consent edit itself) dumped EVERY team idiom
at full text because nothing scoped it.

Fixed

• Docs/config-only turns no longer trigger the Stop idiom review. The gate
  treated every recorded edited file as idiom-governed, so a turn that touched
  only CLAUDE.local.md (or any markdown/config file) resolved zero archetypes
  and the renderer's cannot-scope fallback dumped the full text of every
  not-yet-seen idiom — including a Language: ruby service idiom for a
  markdown edit. A file now counts as idiom-governed only when
  detect_language recognizes it, with a notebook .ipynb counting as python
  source (it keeps its review and now participates in the test-run nudge like
  any python file); a turn with no governed file skips the review (check-event
  reason no_governed_files) without burning the once-per-session marker.

• Language-scoped idiom filtering at the Stop review. An idiom whose
  Language: tag names a recognized language (typescript/ruby/python)
  the turn did not edit is dropped from the review; untagged, Language: any,
  and unrecognized tags fail open to shown, and only the metadata region
  before the first fence is sniffed (a Language: line inside a fenced
  example is example code). Composes with the existing archetype filter, so a
  mixed-language repo's review no longer dumps other-language idioms when
  archetype resolution comes up empty. In a single-profile repo with a
  declared secondary language (language_hint.secondary_detected, the
  rails-with-frontend shape) the primary-language tag cannot discriminate —
  teach stamps every idiom with the profile's primary language — so
  primary-tagged idioms are never language-dropped there.

Changed

• The durable off-switch is now discoverable where the pain is. The
  enforce-mode block message names .chameleon/config.json
"enforcement": {"idiom_review": false} (per-repo, committed → team-wide,
  survives new chats) alongside the existing inline-ignore hint; the
  /chameleon-disable skill gained a "Silencing ONE surface durably" section
  (idiom_review: false, stop_backstop: false, stop_block_cap: 0) and
  routes the recurring-Stop-text complaint to the config key instead of a
  session-only disable; architecture.md and the env-vars reference document
  the same path.
