- Action: Initialized workspace and governance files.
- Context: "Phase 1" focus.
- Observation:
package.jsoncontains both@monaco-editor/reactandprosemirror-*.PLAN.mdprioritizes Monaco.architect-lognotedEditorView.tsxuses ProseMirror. - Decision: Established
PROJECT_BRIEFandSTATEbased onPlan/PLAN.md. - [2026-02-05] Phase 1 Cleanup Complete:
- Architecture: Removed ProseMirror specific code (
EditorView.tsx,mistral-plugin.ts,editor.ts) and uninstalled ~10 dependencies. - Feature: Ported
Ctrl+Ktrigger toMonacoEditor.tsxusingaddCommand. - Verification:
npm run buildpassed.git diffconfirms clean state. - Governance: Addressed Council YellowLight via static analysis (confirmed no orphans).
- Architecture: Removed ProseMirror specific code (
- [2026-02-06] Phase 1.5 Complete: AI SDK implemented with Mistral support, Zod validation, and AICommandPalette UI. Build verified.
- [2026-02-06] Phase 2 Start: Transitioning focus to UI/UX Polish (Glassmorphism, Animations).
- [2026-02-06] Phase 2: UI Overhaul (Blueprint Completion)
- Action: Implemented "Charcoal" aesthetic (#0d0e0d) across all core screens (Login, Dashboard, Modal, Loading, Editor).
- Tooling: Strictly used Codex CLI for code generation as requested.
- Outcome:
npm run buildpassed. UI matches Blueprint specs (Austere, Code-Editor vibe).
- [2026-02-09] UI Refinement + Functional Wiring Pass
- Action: Rebuilt
src/ui/EditorPage.tsxto a Prism-style 3-pane editor with working controls, compile status, right-rail tabs (Preview/Assistant/Activity/Comments), actionable diagnostics, and local assistant/comment flows. - Action: Refined
src/ui/Dashboard.tsxhierarchy (denser header controls, search affordance, visual consistency with editor shell). - Verification:
npm run buildandnpm test -- --runboth pass. - Showcase: Captured updated screens in
showcase/after/(dashboard + editor tab states).
- Action: Rebuilt
- [2026-02-09] Total Overhaul Program Implementation (Phased Gates A-F in-review)
- Phase 0 Artifacts: Added
Plan/acceptance_thresholds.md,Plan/gate_scorecard.md,Plan/prism_parity_matrix.md,Plan/prism_parity_checklist.md,Plan/gate_self_critique.md,Plan/security_headers_and_csp.md, andPlan/baseline_behavior_map.md. - UI Overhaul (Phases 1-3): Applied hard-square tokenized design system across dashboard/editor/auth/workspace/modals/shared components. Updated
src/index.cssandtailwind.config.jsfor square-edge enforcement and unified primitives. - Core/Backend Refactor (Phase 4): Added
DataStore,AuthService,CryptoVault,CompileService, provider-id normalization, parity data types, and de-duplicated compile path scaffolding. - Correctness Fixes: Resolved magic-link token validation, removed
tex-compilerself-import smell, and introduced session/master-key lifecycle handling including unlock route support. - Security Hardening (Phase 5): Encrypted AI key persistence via vault, introduced AI egress policy checks, removed remote worker CDN import path, and added CSP baseline to
index.html. - Parity Stubs (Phase 6): Added near-term local stub contracts in
src/core/parity/featureStubs.ts. - Verification Constraint: Runtime verification commands were not executable in this shell due missing
node/npm.
- Phase 0 Artifacts: Added
- [2026-02-10] Validation + Hotfix Session
- Validation:
npm run buildpasses,npm test -- --runpasses (4 files, 10 tests) after PATH-resolved Node execution. - Incident: Sign-in failures reproduced during manual testing.
- Root Cause: HKDF extractability assumptions conflicted with WebCrypto behavior, causing auth key lifecycle breakage.
- Fixes:
- Restored non-extractable HKDF in
src/core/crypto.ts. - Made wrapped master-key persistence best-effort/non-fatal in
src/core/auth/masterKeySession.tsandsrc/core/auth/AuthProvider.tsx. - Added admin test-entry mode in
src/ui/auth/LoginScreen.tsxand role handling insrc/core/storage/local.ts.
- Restored non-extractable HKDF in
- Documentation Update: Meticulously refreshed
Plan/PLAN.mdandPlan/ROADMAP_CHANGELOG.mdto reflect current program state, gate posture, and next sprint priorities.

- Updated
Plan/PLAN.mdwith current evidence, risk posture, and active testing direction. - Updated
Plan/ROADMAP_CHANGELOG.mdwith incident handling and serving diagnostics. - Updated
STATE.yamlto remove stale toolchain-gap risk and add active preview/parity-link risks. - Updated gate/parity threshold artifacts to remove stale validation assumptions and align with current session truth.
- Updated
- Action: Switched the backend AI adapter from OpenRouter assumptions to NVIDIA Build’s OpenAI-compatible endpoint.
- Backend:
- Provider locked to
nvidiafor this phase. - Endpoint:

- AI key stored encrypted at rest in local secret store; never logged.
AI OFFpolicy still blocks all outbound AI calls at the backend gate.
- [2026-02-10] P0 Recovery Hard Reset + Meticulous Governance Refresh
- Context: User feedback flagged current editor as cluttered, directionless, and functionally unreliable.
- Implementation (UI/IA):
- Replaced monolithic editor flow with shell-based composition:
