# Titan: final-release ## Mandate Final release-readiness gauntlet for v0.8.3-legion. Re-runs the release-titan audit (265+ criteria from `project_v083_release_titan_phase2_complete`) extended with: - chromedevtools-titan criteria (CDP MCP tools work, schemas regenerated, tri-platform validated) - playwright-titan criteria (engine matrix green, no layering collision with CDP) - rtk-titan criteria (decision landed — adopt or reject, both acceptable) - spec-kit-titan criteria (`.specs/` present, lint passes, retroactive examples exist) - cu-bulletproof-v2 criteria (CU ≥95/100, all 4 deferred items closed) - marketing-titan criteria (all v083-legion assets staged, diffs paste-able) Per [[no-ship-without-real-install-e2e]] — every documented install path MUST have a matching E2E gate run on each target OS. Per [[half-shipped-subsystem-bug-class]] — every settings.json/.mcp.json registration MUST resolve to a real script. Runs LAST. Depends on all 6 prior titans completing. ## Deliverables | Artifact | Path | |---|---| | Re-audit criteria | `.local/blueprints/v083-titan-final-release/criteria-v083-legion.md` (extends baseline 265) | | Re-audit results | `.local/blueprints/v083-titan-final-release/audit-results.md` | | Merged CHANGELOG | `CHANGELOG.md` (merges CHANGELOG_TITAN_*.md — SERIALIZED, single owner) | | Install E2E gates | `.github/workflows/install-e2e-{darwin,linux,windows}.yml` (verify present or add) | | Final release report | `.local/blueprints/v083-legion/FINA
