feat(domain): add capability registry evaluator - #106
Conversation
Implements the pure capability-registry eligibility evaluator for the Decision 063 / Decision 064 enforcement boundary. Adds the first domain enforcement point for exact (providerId, agentId, purpose) eligibility against one supplied registry version object. The evaluator is pure, total, fail-closed, and unwired: * no registry admission; * no registry storage; * no registry loading; * no registry pinning; * no routing; * no invocation; * no worker execution; * no Cockpit; * no D061/D062 changes. Validation: * focused capability-registry tests pass; * full npm run verify passes; * F1 Map-prototype poisoning exploit fails closed; * F2 oversized Proxy entries exploit fails closed.

Fixes two Codex P1 findings on PR #106. C1: Revoked Proxy values could make Array.isArray throw before the evaluator returned a fail-closed verdict. The evaluator now classifies arrays through a private safe classifier and maps thrown classification to the existing refusal reason at each site. C2: Number.isInteger was resolved through the live global after hostile getters could run. The evaluator now captures Number.isInteger at module initialization and uses the captured reference inside readLength. Scope remains pure capability-registry evaluator only: * no registry admission; * no registry storage; * no registry loading; * no registry pinning; * no routing; * no invocation; * no worker execution; * no Cockpit; * no D061/D062 changes. Validation: * focused capability-registry tests pass; * full npm run verify passes; * independent re-validation of C1/C2 repair is CLEAN.

Fixes Codex C3 on PR #106. The capability-registry evaluator introduced by PR #106 is now exported through the domain barrel, making its public symbols reachable through the package entry point. The capability-registry test import now resolves through the domain barrel, so public reachability is exercised by the focused test suite. Scope: - src/domain/index.ts barrel re-export only; - capability-registry test import path only; - no evaluator behavior change; - no registry admission; - no registry storage; - no registry loading; - no registry pinning; - no routing; - no invocation; - no worker execution; - no Cockpit; - no D061/D062 changes. Validation: - focused capability-registry tests pass; - full npm run verify passes; - independent C3 barrel-export validation is CLEAN.

Fixes CodeRabbit CR1 on PR #106. The module-level mutable-state guard in the capability-registry test used a sticky regex, so it only evaluated index 0 of the module source. Because the module begins with a block comment, the guard could pass vacuously. Replace it with a column-zero multiline anchor so module-level let/var declarations are detected while indented function-local declarations remain allowed. Scope: - tests/domain/capability-registry.test.ts only; - no production behavior change; - no evaluator source change; - no registry admission; - no registry storage; - no registry loading; - no registry pinning; - no routing; - no invocation; - no worker execution; - no Cockpit; - no D061/D062 changes. Validation: - focused capability-registry tests pass; - full npm run verify passes; - independent CR1 validation is CLEAN.

exportandlet/var. A legal declaration such asexport /* comment */ let cached = 1bypasses it, so the structural test can pass after mutable module state is introduced.
