chameleon 2.38.30

Round 2 (full) of whole-plugin depth QA: an adversarial sweep across all seven
frameworks and three languages, driving real hooks and tools against real
profiled repos, with every finding independently verified before it counted.
Fifteen confirmed defects, all advisory-quality (no crash, leak, or deny bypass),
each fixed and re-verified on the repo that surfaced it.

Fixed

Guidance quality (framework archetypes were under-served):

• DRF serializers / Django models got no base-class contract on the first edit.
  A base-only class contract (extends BaseSerializer, models.Model, AppConfig) was
  dropped upstream when the cohort had no macros/methods, so the Tier-2 facts block
  showed nothing. It now falls back to the derived dominant base, matching the
  Tier-1 echo.
• Class-heavy archetypes in few files derived zero conventions. DRF/Django pack
  many classes into one serializers.py / models.py per app, and the sample gate
  counted files, not classes, so a 5-file / 67-class serializer archetype was
  suppressed entirely. The inheritance / class-contract / key-export gates now
  count classes too.
• NestJS feature-module edits mirrored the root AppModule. The imports-only
  aggregator won the canonical-witness tiebreak. Imports-only @Module files are
  now demoted so a real feature module (controllers + providers) is the witness.
• Rails job witness was the abstract ApplicationJob base (no perform). Abstract
  application_*.rb bases are now demoted below their concrete siblings.
• Rails migration witness carried an obsolete Migration[4.2] version. A
  migration behind the cluster's newest schema version is now demoted, so a
  current-version migration is the witness.
• Ruby reuse hints listed ambiguous bare Send / Add / Remove. Block-nested
  Rails service classes collapse to their leaf name; a leaf defined in 2+ files is
  ambiguous and is now dropped from the "reuse these" list.

Correctness (hints and advisories were wrong or noisy):

• PostToolUse block override hint printed a literal <rule>. For blanket-immune
  rules (eval-call, secret) a bare-token ignore does not clear the block, so the
  hint now names the actual failing rule.
• Django model->migration nudge told Python users to type // (a syntax error).
  The silence hint now uses # for Ruby/Python and // for TS/JS.
• Cross-file break advisory false-fired on member access. Dropping an
  import { foo } binding while keeping an unrelated self.foo() member call
  reported a phantom broken import; a preceding . is no longer counted as a
  bareword reference.
• Named-export-count-bucket mismatch read as "Fix these" on small new files. A
  new single-route or single-form file has fewer exports than the archetype's
  typical count; the info-severity signal now carries the same "not a defect, do
  not restructure" hedge its shape-mismatch sibling has.
• Monorepo call-graph tools emitted non-round-trippable paths. get_callers /
  get_callees / get_blast_radius / query_symbol_importers answered from the file's
  nested workspace profile with workspace-relative paths, while search / describe
  emitted repo-root-relative ones; chaining an emitted caller path back silently
  returned total=0. All four now emit paths in the repo-arg root space, so they
  round-trip.

Degraded-state honesty (silent failures now surface):

• Corrupt calls_index.json silently zeroed god-symbols and caller counts.
  describe_codebase and search_codebase now set degraded when the call index is
  present but unreadable, like they already do for a corrupt symbol index.
• Corrupt enforcement.json silently disabled all edit-time deny/block. The
  per-edit advisory now shows an "Enforcement degraded" banner when
  enforcement.json is present but unparseable, matching the config.json banner.
• Refresh that repaired a corrupt conventions.json silently dropped taught banned
  imports. The refresh envelope now carries a taught_import_warnings warning
  when preservation was impossible, instead of reporting a clean success.
• Statusline upgrade banner was missing in the no-jq path when CLAUDE_PLUGIN_ROOT
  was unset. The python fallback now derives the plugin root from the script
  location, like the jq path.
