# Session Specification

**Session ID**: `phase35-session10-final-release-gate` **Phase**: 35 - AI Rogue Audit Hardening And Refactor **Status**: Not Started **Created**: 2026-06-27

***

## 1. Session Overview

This session performs the final Phase 35 release gate for AI Rogue after audit rebaseline, regression coverage, accessibility, renderer, persistence, simulation, bridge, world/type, documentation, and media-policy work have completed. It is next because the analysis script reports Phase 35 Session 10 as the only unfinished candidate and the phase PRD records Sessions 01-09 as complete.

The work is validation and evidence focused. It reruns the full local gate bundle, AI Rogue focused gates, Cloudflare Pages static demo gates, D3 privacy and capability scans, deterministic playthroughs, and final documentation checks. If a gate fails, the session must either fix a directly related release blocker within the same release effort or mark the release No-Go with concrete evidence.

The result should be a durable final release posture: exact pass/fail command evidence, an updated Phase 35 PRD closeout section, refreshed AI Rogue release notes where needed, and a clear Go/No-Go recommendation that preserves the production default, browser-local state, static Pages boundary, and no-new-D3 privacy posture.

***

## 2. Objectives

1. Run the full app, AI Rogue, Pages, privacy, budget, asset, and playthrough gate matrix with exact command evidence.
2. Confirm AI Rogue remains production default-enabled with `VITE_CLAUDE_OS_ENABLED_EXTENSIONS=none` as the explicit disable path.
3. Confirm no new D3 privacy or hosted-capability finding is promoted by source, test, or built-artifact evidence.
4. Update final release evidence and produce a concrete Go/No-Go recommendation for current AI Rogue production posture.

***

## 3. Prerequisites

### Required Sessions

* [x] `phase35-session01-rebaseline-audit-evidence` - Reconciled live versus historical AI Rogue audit findings and preserved current D3 boundary evidence.
* [x] `phase35-session02-fixed-blocker-regression-coverage` - Preserved direct regression evidence for original default-enable blockers.
* [x] `phase35-session03-runtime-accessibility-controls` - Completed runtime summary, compact control, Large HUD, and mobile accessibility coverage.
* [x] `phase35-session04-renderer-robustness-and-scheduling` - Hardened renderer, resize, asset-load, AudioContext, decode, and disposal fallbacks.
* [x] `phase35-session05-persistence-schema-contracts` - Stabilized browser-local wallet, ledger, save-slot, migration, reset, and storage failure contracts.
* [x] `phase35-session06-simulation-ownership-refactor` - Narrowed runtime and simulation ownership while preserving production behavior.
* [x] `phase35-session07-renderer-and-react-bridge-refactor` - Split renderer, React bridge, hooks, controls, audio adapter, and assistive summary ownership.
* [x] `phase35-session08-world-types-and-fixture-cleanup` - Split world/type modules and protected deterministic fixture boundaries.
* [x] `phase35-session09-documentation-and-media-policy-sync` - Synced current AI Rogue docs with Web Audio, media caps, production default enablement, browser-local state, and no-bridge boundaries.

### Required Tools Or Knowledge

* Bun 1.3.14 project environment and package scripts in `package.json`.
* Playwright Chromium projects from `playwright.config.ts`.
* `rg`, `git`, `gzip`, shell utilities, and existing project gate scripts.
* Current AI Rogue release docs under `docs/extensions/ai-rogue/`.
* Phase 35 evidence source in `.spec_system/PRD/phase_35/PRD_phase_35.md`.

### Environment Requirements

* Run from the repository root.
* No external dashboard, deploy, credential, or network-only action is required.
* Local browser automation must be available for Playwright gates.
* Preserve existing browser-local and static-demo safety boundaries.

***

## 4. Scope

### In Scope (MVP)

* AI Rogue maintainers can trust final local quality evidence - run typecheck, script typecheck, lint, format check, whitespace check, full Vitest, AI Rogue focused tests, host extension tests, production build, bundle budget, asset-size, and private-runtime checks.
* AI Rogue maintainers can trust playable runtime evidence - run the AI Rogue browser gate group and deterministic playthrough script, recording win, loss, and active-at-cap outcomes.
* AI Rogue maintainers can trust static public-demo evidence - run Pages demo build, scan, budget, desktop route smoke, mobile route smoke, no-bridge checks, and mobile no-overflow checks.
* AI Rogue maintainers can trust D3 privacy and capability evidence - rerun targeted scans for bridge calls, hosted writes, collectors, analytics, Functions, remote game-content loading, private paths, credentials, raw prompts, provider bodies, raw telemetry, WebGPU-only paths, worker protocols, and source dumps.
* AI Rogue release readers can understand the decision - update Phase 35 PRD release evidence and AI Rogue release docs with exact pass/fail results, caveats, and a Go/No-Go recommendation.

### Out Of Scope (Deferred)

* Adding new AI Rogue capabilities - Reason: collectors, WebGPU, workers, remote loading, hosted writes, analytics, expanded content, and public-demo live runtime require fresh review.
* Starting unrelated feature work after release validation begins - Reason: the session owns release posture, not new product scope.
* Deploying to Cloudflare Pages or Workers - Reason: the stub requires local Pages build, scan, budget, and smoke evidence, not an external deployment.
* Broad documentation rewrites unrelated to final evidence - Reason: Session 09 already synced docs; this session updates release evidence and caveats.

***

## 5. Technical Approach

### Architecture

Use existing project gate scripts and tests as the release contract. Record all commands and exact outcomes in `.spec_system/specs/phase35-session10-final-release-gate/implementation-notes.md` so the PRD closeout can cite concrete evidence instead of relying on prior Phase 34 results.

Run build-dependent checks in dependency order: production build before app bundle budget and app chunk scans; Pages demo build before Pages scan, Pages budget, and Pages route smoke. Run AI Rogue browser tests through Playwright's `chromium` project and Pages smoke through the `pages-demo-chromium` project. Use source scans plus available built chunks to prove D3 boundaries.

If a gate fails, inspect whether the failure is a release-blocking regression inside the AI Rogue/Pages/static-demo scope. A scoped fix may be implemented and rerun in the same session; otherwise the evidence must mark the release No-Go with the failed command, affected boundary, and blocker.

### Design Patterns

* Evidence ledger: One release-gate matrix records command, result, evidence, caveat, and follow-up status.
* Existing gates first: Prefer current scripts, package commands, and e2e specs over ad hoc validation.
* No-new-capability posture: Treat any collector, hosted write, remote loading, WebGPU-only path, worker protocol, analytics, or public-demo bridge signal as release-impacting unless proven to be a false positive.
* Caveat classification: Keep tight bundle headroom and active-at-cap playthrough outcomes visible without promoting them to blockers unless new evidence shows a budget violation or soft-lock.

## 7. Success Criteria

### Functional Requirements

* [ ] All required local gates pass or the release is explicitly marked No-Go with concrete blockers.
* [ ] AI Rogue browser gates prove the Play route canvas, input, persistence, ledger, mobile, and enablement behavior still work.
* [ ] Pages desktop and mobile smoke prove static routes render product surfaces without `/__*` bridge requests or mobile document overflow.
* [ ] D3 scans find no new AI Rogue bridge calls, hosted writes, collectors, analytics, Functions, remote game-content loading, private paths, credentials, raw prompts, provider bodies, raw telemetry, worker protocols, WebGPU-only requirements, or source dumps.
* [ ] Final docs state the current Go/No-Go decision and caveats without promoting historical blockers or stale Phase 30/34 evidence as current.

### Testing Requirements

* [ ] Typecheck, script typecheck, lint, format check, whitespace check, full Vitest, AI Rogue focused tests, host extension tests, production build, budget, asset-size, and private-runtime gates complete.
* [ ] AI Rogue focused Playwright gate group completes under `chromium`.
* [ ] Pages build, scan, budget, desktop route smoke, and mobile route smoke complete under local static-demo mode.
* [ ] Deterministic AI Rogue playthrough output is recorded and classified.
* [ ] Targeted source and built-chunk scans are recorded and classified.

### Non-Functional Requirements

* [ ] AI Rogue remains browser-local with no hosted write path.
* [ ] Public demo remains static-only with no local bridge dependency.
* [ ] Bundle and Pages budgets remain within the configured 1500 KB total JS gzip and 300 KB CSS caps, or the release is No-Go.
* [ ] Documentation updates are evidence-only and avoid unrelated reflow.

### Quality Gates

* [ ] All files ASCII-encoded.
* [ ] Unix LF line endings.
* [ ] Code follows project conventions.
* [ ] Product surfaces contain product-facing copy only; diagnostics remain in tests, local dev-only surfaces, or release evidence artifacts.

## 8. Implementation Notes

### Working Assumptions

* Session 10 is executable now: The analysis script reports `current_phase` 35, `current_session` null, completed sessions include Phase 35 Sessions 01-09, and the only unfinished candidate is `session_10_final_release_gate`. Planning can proceed because all listed prerequisites are complete.
* Phase 34 evidence is a baseline, not the final Phase 35 release result: `.spec_system/SECURITY-COMPLIANCE.md` and Phase 35 PRD record a clean Phase 34 closeout, but the Session 10 stub explicitly requires rerunning the gate bundle after Phase 35 hardening and docs updates.
* The final gate can end in Go or No-Go: The session stub says any failed gate becomes either a fixed blocker in the same release effort or an explicitly documented No-Go condition. Planning can proceed because both outcomes have concrete evidence artifacts.
* Cloudflare Pages validation is local static-demo validation: `package.json` provides `demo:build:pages`, `demo:scan:pages`, and `demo:budget:pages`, and `playwright.config.ts` defines a local `pages-demo-chromium` project. External deployment is not required for this session.

### Conflict Resolutions

* The master PRD phase table still marks Phase 35 as "Not Started", while the analysis script and `.spec_system/PRD/phase_35/PRD_phase_35.md` mark Phase 35 as in progress with 9/10 sessions complete. The chosen interpretation is that the analyzer and phase PRD are current for session planning, because the analyzer is the workflow authority and the phase PRD contains validated Session 01-09 progress.
* Prior Phase 34 gate results show Production Go, while the Session 10 stub still requires a final release gate. The chosen interpretation is that Phase 34 remains historical baseline evidence and Session 10 must produce fresh Phase 35 evidence after refactors and docs sync.

### Key Considerations

* Keep tight bundle headroom visible: Phase 34 recorded 1490 KB / 1500 KB JS gzip and 275 KB / 300 KB CSS.
* Keep active-at-cap playthrough outcomes visible: Phase 34 recorded 2 wins, 1 loss, and 3 active-at-cap outcomes across 6 deterministic seeds.
* Keep D3 evidence precise: distinguish harmless product-local data attributes from real bridge calls, hosted writes, collectors, analytics, raw telemetry, remote loading, worker protocols, or WebGPU-only requirements.
* Do not let release evidence imply approval for new AI Rogue capabilities.

### Potential Challenges

* Full gate commands may be slow or order-dependent: Mitigate by recording each command independently and running build-dependent checks only after the matching build exists.
* Scan regexes may match expected docs or deny-list text: Mitigate by classifying false positives in the release evidence ledger.
* Playwright failures may be environmental: Mitigate by preserving trace and error evidence, rerunning only after a scoped diagnosis, and marking No-Go if product behavior cannot be proven.
* Built artifacts may be stale after failed builds: Mitigate by treating chunk and Pages scans as valid only after the matching build command passes.

### Relevant Considerations

* \[P34] **AI Rogue is production default-enabled**: The final gate must preserve default visibility and explicit `none` disable behavior.
* \[P31-P34] **Pages and AI Rogue CI guards deferred**: Manual Pages and AI Rogue gates remain required release evidence.
* \[P31-P34] **Public-demo and AI Rogue gates stay bundled**: Private-runtime, no-bridge, budget, route smoke, asset-size, and playthrough checks should be interpreted together.
* \[P30/P32/P34] **Route-lazy runtime ownership scales**: Keep Pixi behind the Play route/local facade and verify route-scoped runtime behavior.
* \[P30/P32/P34] **Schema-backed browser-local state works**: Preserve schema ownership for localStorage and IndexedDB state during final verification.
* \[P30/P32/P34] **Do not widen AI Rogue capabilities without review**: New collectors, WebGPU, workers, remote loading, hosted writes, or expanded content remain out of scope.

## 9. Testing Strategy

### Unit Tests

* Run `bun run test` for the full Vitest suite.
* Run `bun run test -- src/extensions/ai-rogue` for AI Rogue focused unit and component coverage.
* Run host extension unit tests covering registry, setup config, and settings extension behavior.

### Integration Tests

* Run `bun run build` followed by `bun run budget:check`.
* Run `bash scripts/check-asset-sizes.sh`.
* Run `bun run runtime:check-private`.
* Run `bun run demo:build:pages`, `bun run demo:scan:pages`, and `bun run demo:budget:pages`.

### Runtime Verification

* Run Playwright AI Rogue browser specs under the `chromium` project.
* Run Pages desktop and mobile route smoke under the `pages-demo-chromium` project.
* Run `bun run scripts/ai-rogue-playthrough.ts` and classify all six seed outcomes.
* Run targeted source and built-chunk scans for D3 privacy and capability boundaries.

### Edge Cases

* Active-at-cap playthroughs remain non-blocking only if no new soft-lock or unwinnable-loop evidence appears.
* Budget checks are blocking if total JS gzip or CSS caps are exceeded.
* Pages smoke is blocking if any public route calls `/__*` or mobile document overflow appears.
* Privacy scans are blocking if a match represents a real new bridge, hosted write, collector, analytics, remote-loading, raw private-data, worker, or WebGPU-only path.
