Spec v0.3 (additive): intent-bound repositioning + hardening clauses#5
Merged
Conversation
Repositions to intent-bound action authorization (abstract, PDP/PEP framing, firewall=analogy). Adds: testable broker query obligation (§4.2, additive — breaking fingerprint query-fold deferred); policy-validation fail-closed (§5.1); authorization properties P1-P4 (§7.1); head-anchoring truncation defense (§8.3); rate-limit consistency class; authorization-token optional profile with cns/revocation/interop (§9). New CTK vectors (resolve P1/P3 wired + passing; broker_query/policy_invalid staged). validate + conformance green. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

…ng (§9, §11) Combines this PR's breaking work with the additive #5 base now on main: adopts the §4.2 query-fold + exact canonicalization (was tracked as deferred), adds JWS algorithm-confusion defense, kid/key-separation, exp<=300s, cross-instance jti sharing, and the token-replay/key-separation §11 considerations — on top of #5's cns single-use, revocation, and interop. Marks the spec FROZEN at 0.3 (badge, header, CHANGELOG). validate.py + conformance.py green against delego 0.2.3; query-fold hashing vectors ship when the reference implements the fold.

Additive v0.3 draft changes — no breaking preimage change (the query-fold is intentionally deferred).
