 ## [Unreleased]
 
-### Documentation
-- docs(spec): clarify Import.as required (#25)
+## [1.5.0] - 2026-05-15
+
+### Added
+- Core: protocol-shape the spec — canonical schema, 18 conformance fixtures, RFC 2119 conformance section, discovery conventions (Phase 1)
+- Core/CLI: dry-run executor, CI hardening, expanded CLI tests, benchmarks scaffolding (Phase 2)
+- Core: tier-1 semantic canaries on compiled prompt output (#54) — 13 pinned assertions on executive phrasings the compiler must produce (output-schema rendering, quality gates, retry context, strategy preamble, branch context, step identity); regression-fires loudly if a refactor drops them.
 
 ### Changed
 - chore(deps): align toolchain on Node 22 LTS (#24) — CI runner bumped from Node 20 → 22; `@types/node` downgraded from `^24.12.2` → `^22.19.17` across root + `@logic-md/cli` + `@logic-md/mcp`; root `engines.node` declared as `>=22.0.0`. Closes the runtime/types gap introduced by PR #23.
 - chore: bump TypeScript to 6.0.3 (from `~5.8.0`) across root + `@logic-md/cli` + `@logic-md/mcp`. No source edits required; full build, test, and conformance suites green on 6.0.3.
+- chore(deps): bump ajv 8.18.0 → 8.20.0 (#38), yaml 2.8.3 → 2.8.4 (#43), zod 4.3.6 → 4.4.3 (#42), tinyglobby 0.2.15 → 0.2.16 (#14).
+- chore: organisation rename SingleSourceStudios → SingularityAI-Dev across repo URLs and metadata.
 
 ### Fixed
+- Core schema: enforce `[0, 1]` bounds on probability/score fields, split violation enums into precise variants, fix dist build (7e48f4a). Previously-accepted out-of-range values are now rejected by `@logic-md/core` validators.
 - Docs: SPEC.md §4.1 `Verification.on_fail` inline comment now documents all five schema-permitted values (`retry`, `escalate`, `skip`, `abort`, `revise`); added §4.1.1 Verification Properties table with per-value semantics; added conformance fixture `009-verification-revise` covering step-level `on_fail: revise` (#16).
 
+### Documentation
+- docs(spec): clarify Import.as required (#25)
+- docs: add `llms.txt` at repo root (#52)
+- docs: README positioning pivot (#50)
+- benchmarks: publish 2026-05-07 cross-model results (#49)
