Security hotfix — v0.15.1 Wave 1 fixes from 4-parallel audit. RED-1 (CVE): KEI_DISABLED_HOOKS tokenized match — was `*all*` substring-glob (trivially bypassable via "install", "wall-clock", etc.), now exact-token split on comma/space. Patched in all 9 hooks: no-hand-edit-agents, assemble-agents, assemble-validate, tomd-preread, agent-fork-logger, site-wysiwyd-check, error-spike-detector, milestone-commit-hook, session-end-dump. RED-2 (observability): minimal profile whitelist now includes agent-fork-logger and session-end-dump (ledger + trace paths) so observability is not silently lost on minimal installs. HIGH: review.json schema minItems:1 on findings — rejects empty reviews; new Rust test review_schema_rejects_empty_findings. HIGH: typed-handoff wire-up — produces_artifact declared at top level on 5 manifests (kei-security-auditor, kei-validator, kei-architect, kei-code-implementer, kei-critic); duplicate per-handoff declarations removed. MED: kei-artifact validate.rs gains warn_unsupported_keywords — non-fatal stderr warning when schema uses keywords outside the hand-rolled 2020-12 subset. LOW: CI Node matrix dropped 18, now ['20','22']. Doc drift: skills/hooks-control/SKILL.md reflects tokenized-match semantics and updated minimal-profile hook list. Tests: 191 Rust workspace + 30 assembler (both pass). RED-1 reproducer 10/10 (4 former-CVE vectors blocked, 5 legit vectors accepted, empty passes).
