Conversation
- CLAUDE_MODEL_ALIASES["opus"] now resolves to claude-opus-5 instead of the floating "opus" alias, matching the existing Sonnet 5 pin. - CLAUDE_CODE_CAPABILITIES.min_version raised from 2.1.142 to 2.1.219, Anthropic's documented Claude Code floor for launching Opus 5. - Updated alias-registry, translation, capability, doctor, startup- readiness, and session-launch tests to match. - Updated the conformance-probes.yml CI matrix and its workflow-shape test to a single 2.1.219 job per platform (both prior pinned versions fall below the new floor). - Documented the new floor/matrix and the opus->claude-opus-5 default in docs/execution/claude-startup-readiness.md and docs/configuration.md. Recipe/skill YAML opus[1m] references, historical claude-opus-4-6 fixtures, and the family-level drift-normalization logic are intentionally unchanged.

Summary
Pins the logical
opusmodel class to the physicalclaude-opus-5model ID instead ofthe previous floating
opus -> opusalias, matching the existing Sonnet 5 pin pattern.Raises the enforced Claude Code CLI floor from
2.1.142to2.1.219, which Anthropicdocuments as the minimum Claude Code version required to launch Opus 5. Updates the
alias-registry, translation, capability, doctor, startup-readiness, and session-launch
tests to match the new deterministic mapping and floor, collapses the
conformance-probes.ymlCI matrix from four pinned-version rows to two (both priorpinned versions now fall below the new floor) plus its workflow-shape test, and
documents the new floor/matrix and default in
docs/execution/claude-startup-readiness.mdand
docs/configuration.md.Logical
opus/opus[1m]references in recipe/skill YAML, historicalclaude-opus-4-6telemetry/parser/drift fixtures, and the family-level drift-normalization logic are
deliberately left unchanged, as are the unrelated
2.1.197/2.1.91references indocs/verification/review-pr-immunity.mdandtests/arch/test_recipe_delivery_provenance.py.Verified with
