PolyCodeGraph 0.9.0

PolyCodeGraph 0.9.0 corrects review noise and adds optional lean context while retaining audit rendering and semantic provider contracts.

• Exact unchanged source intervals distinguish relocated sites from semantic additions/removals. Before/after positions remain recoverable; uncertain mapping remains conservative.
• Strict baseline scope rejects typos/excluded files and requires explicit intended new files. Lean capture is strict; audit can opt in.
• format: lean (pcg-lean-1) keeps full IDs, distinct sites, confidence and source hashes, with separate required inventory, optional context and external verification. Audit remains the default.
• Archives include an optional Python LeanAdapter/Observer; it is not automatically installed into Codex. Separate instrumentation is provided for wire payloads and client insertion; actual model input remains unmeasured.
• Comparison tooling preserves failures, retries, unknown usage, frozen artifacts and interrupted attempts instead of inventing economic results.

Activation and rollback · Updated harness · Local validation

Validation: 88 Rust tests, 37 Python tests, native intents and audit/lean rename site parity on all ten languages plus Flutter, primitive differential checks against verified 0.6, Android SDK, Unicode/CRLF relocation and strict scope, and relocated Linux package/client-adapter checks. The deterministic rename gate preserves 19 reference sites and 17 oracle context checks across every page/expansion. These tests do not measure AI task cost.

No new AI benchmark was run for 0.9. The earlier 0.8.0-rc.1 pilot and the frozen post-0.8 experiments retain their original identities and limitations. AI usage, monetary improvement and robust economic gates remain not measured for this release.

Source: f1e0484cb1ac66f0fe623fc6e8c4531a886b0a07, based on stable 0.8.0 (64f7dfb0bfcae4f6471ee691dfdc896a34ac785f).

All 20 jobs passed for this exact source in release CI: Linux/Windows/macOS core and native checks, Flutter, Android, macOS UIKit, query benchmark, and four native packages. Archive manifests, platforms, bundled workers/client adapter, permissions and SHA-256 digests were checked before publication.

Download the archive for Linux x64, Windows x64, macOS Intel or macOS Apple Silicon, extract it, and keep the executable beside providers/. Use SHA256SUMS to verify the archive. See README for required runtimes of selected language providers.
