OMK

Added

• Added reasoning-router-resolver.ts as the shared thinking-level resolver core for the v4 reasoning router, centralizing resolveThinkingLevelCore, TASK_CLASS_THINKING_LEVELS, lane-step adjustment, bounded bias/hint fusion, confidence escalation, and available-level clamping.
• Added deterministic capability routing to the subagent example extension, including catalog-backed capability parsing and validation, domain-profile derivation, assigned-capability preambles for bundled agents, optional skill enforcement, unit coverage, the read-only scripts/derive-agent-capabilities.mjs classify/audit CLI, and the scripts/check-agent-capabilities.mjs live-catalog guard.

Changed

• Collapsed automatic reasoning-effort routing to a single /think auto backed by the v4 confidence-bearing router. The /think auto-v1, /think auto-v2, /think auto-v3, and /think auto-v4 variants (plus their auto vN / auto:vN forms) are removed, and /think auto now routes via v4 instead of the former v1 classifier; those variants were opt-in experimental surface introduced in 0.90.4. Manual /think <level> still always takes precedence.
• Changed context-budget v2 observability to inline the legacy token-optimizer compatibility status in the planner/types instead of importing the removed optimizer module; telemetry still reports optimizer_id="legacy-token-optimizer", status="quarantined_compatibility", and active_context_budget_optimizer="context-budget-v2".

Fixed

• Fixed v4 reasoning-router misclassification of real-world, out-of-gold-set phrasing by extending the keyword families with vocabulary the classifier previously had no signal for: review (sanity-check, once-over, eyeball), refactor (tidy up), plan (map out, phases, and Korean 계획 … 세워 with an intervening particle), debug (track down, leak), plus a narrow negation-aware review cue. An out-of-vocabulary adversarial probe improves from 22/30 to 30/30 while the frozen gold-set holdout and full set stay at 100%, guarded by the new 016-reasoning-router-v4-generalization regression test.

Removed

• Removed the v1, v2, and v3 reasoning-router modules (reasoning-router.ts, reasoning-router-v2.ts, reasoning-router-v3.ts, reasoning-router-weights.ts), their regression suites (003-007), and the v3 calibration script; only the v4 router remains, reachable via /think auto.
• Removed the unused compactor.ts module.
• Removed the legacy token-optimizer.ts runtime module and its dedicated test while retaining fixed compatibility telemetry in context-budget v2.
