# Session Specification

**Session ID**: `phase06-session07-collaboration-isolation-and-mobile-validation-closeout` **Phase**: 06 - Collaboration, Isolation, and Mobile **Status**: Not Started **Created**: 2026-05-30 **Package**: Cross-cutting **Package Stack**: TypeScript, JavaScript, Markdown docs, Vitest, Playwright, Biome, npm workspaces

***

## 1. Session Overview

This session validates Phase 06 end to end and closes the collaboration, isolation, and mobile phase with retained evidence, security review, documentation updates, and Phase 07/08 handoff notes. Sessions 01 through 06 already established the Phase 06 requirements baseline, strengthened non-hosted room authority, hardened shared collaboration events, clarified collaborative cockpit UX, exposed local isolation diagnostics, and improved mobile/accessibility behavior.

The closeout work is cross-cutting. It must verify protocol, Worker, web, server, CLI, hook, browser, formatting, linting, typecheck, test, build, secret-scan, ASCII/LF, whitespace, privacy, and documentation evidence without expanding scope into hosted identity, hosted storage, analytics, production-hosted validation, remote execution, Docker execution, mobile certification, WCAG certification, public replay hosting, or trusted erasure.

The result should leave Phase 06 ready for the validate and updateprd workflow steps. Stable docs, package README files, spec-system PRDs, security posture, and implementation artifacts should agree about what shipped, what was validated locally, which evidence is retained, and which risks remain for Phase 07 hosted services and Phase 08 release hardening.

***

## 2. Objectives

1. Validate all Phase 06 collaboration, authority, event, remote-context, isolation, mobile, accessibility, and local-first requirements against tests, browser evidence, docs, and spec-system artifacts.
2. Record command results, retained desktop/mobile evidence paths, security/privacy review, residual risks, and no-certification boundaries in session artifacts.
3. Update PRD, UX PRD, Phase 06 PRD, stable docs, runbooks, and package README files so shipped Phase 06 behavior and Phase 07/08 deferrals are consistent.
4. Produce a concise implementation summary and handoff that makes the next workflow step unambiguous.

***

## 3. Prerequisites

### Required Sessions

* [x] `phase06-session01-collaboration-requirements-and-safety-baseline` - Provides Phase 06 baseline artifacts, routing matrix, mobile/accessibility checklist, and deferral boundaries.
* [x] `phase06-session02-room-authority-and-participant-identity-contracts` - Provides room-local authority, roles, revisions, idempotency, stale-state, and duplicate-decision behavior.
* [x] `phase06-session03-shared-collaboration-event-contracts` - Provides safe collaboration frame families, blocked-field validation, sender exclusion, and bounded catch-up behavior.
* [x] `phase06-session04-collaborative-cockpit-ux-and-remote-context` - Provides visible collaboration lifecycle, role, remote-context, failure, reconnect, leave, and local-only web UX.
* [x] `phase06-session05-isolation-boundary-and-sandbox-diagnostics` - Provides non-executing isolation posture, protocol/server/CLI/hook diagnostics, unsupported-route envelopes, and no-mutation evidence.
* [x] `phase06-session06-mobile-cockpit-and-accessibility-hardening` - Provides mobile reachability, keyboard/pointer/screen-reader, focus, reduced-motion, text-fit, no-overlap, and browser evidence.

### Required Tools/Knowledge

* Node 20+, npm workspaces, TypeScript, JavaScript, Vitest, Playwright, Biome, and the repository scripts in `package.json`.
* Current docs and artifacts: `.spec_system/PRD/PRD.md`, `.spec_system/PRD/PRD_UX.md`, `.spec_system/PRD/phase_06/PRD_phase_06.md`, `.spec_system/PRD/phase_06/collaboration_isolation_safety_baseline.md`, `.spec_system/PRD/phase_06/phase06_requirement_routing_matrix.md`, `.spec_system/PRD/phase_06/mobile_accessibility_acceptance_checklist.md`, `.spec_system/SECURITY-COMPLIANCE.md`, `.spec_system/CONSIDERATIONS.md`, stable docs, package README files, and prior Phase 06 validation reports.
* Package boundaries: `packages/protocol` owns shared contracts, `apps/warroom` owns optional Worker relay behavior, `apps/web` owns cockpit UX and browser evidence, `apps/server` owns loopback diagnostics and unsupported-route envelopes, and `apps/cli` plus `apps/hooks` own local diagnostics and lifecycle posture.

### Environment Requirements

* Local dependencies installed and tests runnable from the repo root.
* Browser evidence may use local server and mocked or same-origin Worker paths only.
* Cloudflare credentials, hosted accounts, analytics accounts, public tokens, Docker daemon, remote runners, media provider keys, and production-hosted deployments are not required.

***

## 4. Scope

### In Scope (MVP)

* Maintainers can trust Phase 06 completion evidence - Run or document focused protocol, Worker, web, server, CLI, hook, browser, formatting, linting, typecheck, test, build, secret scan, ASCII/LF, whitespace, and relevant privacy checks.
* Users can understand validation scope - Record that browser evidence is local and mocked or same-origin Worker evidence, not hosted collaboration, mobile certification, WCAG certification, production-hosted validation, or trusted erasure.
* Security reviewers can see residual risks - Validate collaboration and diagnostics do not leak prompts, file contents, command bodies, terminal output, transcripts, tokens, broad paths, exports, replay buffers, scan payloads, media drafts, local diagnostics, logs, backups, or quarantined historical content.
* Isolation remains non-executing - Validate file, git, terminal, Docker, remote, hosted, Worker, and inbound command execution remain unavailable, deterministic, documented, and non-mutating.
* Stable docs remain aligned - Update master PRD, UX PRD, Phase 06 PRD, architecture, API, privacy/security, deployment, environments, release, runbook, and package README references where Phase 06 status or deferral language is stale.
* Handoff is explicit - Record Phase 07 hosted-services and analytics guardrail work, Phase 08 release hardening and trusted-erasure work, and any residual local validation gaps.

### Out of Scope (Deferred)

* Implementing hosted services, hosted auth, account-backed identity, hosted storage, Supabase, analytics dashboards, public replay hosting, or push - *Reason: Phase 07 owns hosted services and analytics guardrails.*
* Adding real file, git, terminal, Docker, remote, Worker, inbound chat, webhook, or hosted executors - *Reason: execution still needs a separate threat model, authorization, audit, rollback, redaction, tests, and docs.*
* Claiming production-hosted app validation, formal WCAG certification, mobile certification, public collaboration safety, or trusted unified erasure - *Reason: Phase 08 and future audit work own release-grade validation and erasure.*
* Promoting quarantined `EXAMPLES/` content, historical reports, media drafts, or provider outputs into runtime artifacts - *Reason: media and historical-source gates remain active.*

***

## 5. Technical Approach

### Architecture

This closeout is evidence-led. The session should start by inventorying the completed Phase 06 session artifacts, then run focused validation across the packages that own collaboration, isolation, and mobile behavior. Command results, failures, skips, and evidence paths should be recorded in `implementation-notes.md` as the source of truth for the later validation report.

Documentation updates should follow the evidence. PRDs should describe Phase 06 as completed only after tests and browser evidence are recorded. Stable docs and README files should keep local-first boundaries visible: Worker federation remains optional external transfer, the local server remains the loopback runtime, remote context remains separate from local truth, guarded actions remain non-executing, and leave/reset/recovery flows remain narrower than trusted erasure.

Security review should focus on external transfer, redaction, diagnostics, local persistence, browser evidence scope, and residual risk. The review should preserve open findings for hosted identity, trusted erasure, and production-hosted validation unless this session provides source-backed evidence to change them.

### Design Patterns

* Evidence before claims: PRD, docs, and summary updates should cite recorded command and browser evidence.
* Boundary-specific validation: Worker frames, diagnostics, replay, export, logs, browser evidence, docs, and summaries each need explicit privacy review.
* Local-first fallback: Core workflows must remain usable with no Worker URL, Cloudflare credentials, hosted accounts, analytics, Docker, remote runners, media providers, or public tokens.
* Deterministic deferrals: Hosted services, analytics, trusted erasure, production-hosted validation, release cleanup, and legacy decommission should remain Phase 07/08 handoffs.
* Closeout artifacts as handoff: `implementation-notes.md`, `security-compliance.md`, `validation.md`, and `IMPLEMENTATION_SUMMARY.md` should let `validate` and `updateprd` proceed without rediscovering context.

### Technology Stack

* TypeScript 5.9 packages: `packages/protocol`, `apps/server`, `apps/warroom`, `apps/web`, `apps/adapters`.
* JavaScript packages: `apps/cli`, `apps/hooks`.
* React 18, Vite, Zustand, Tailwind, Cloudflare Worker/Durable Object, Express, WebSocket, and local CLI/hook runtime surfaces.
* Validation tools: Vitest, Playwright, Biome, TypeScript `tsc`, npm workspace scripts, checked-in secret scanner, media gates, `git diff --check`, ASCII/LF checks, and manual docs review.

## 7. Success Criteria

### Functional Requirements

* [ ] All Phase 06 sessions are validated and documented with command results, browser evidence, security review, and residual risks.
* [ ] Phase 06 requirements P06-R001 through P06-R035 are closed, explicitly deferred, or documented with source-backed residual risk.
* [ ] Collaboration, authority, remote context, reconnect, disconnect, leave, local-only, unavailable, isolation, and mobile behavior are covered by focused tests and retained desktop/mobile browser evidence.
* [ ] Collaboration and diagnostics validation confirms blocked sensitive categories are not transferred, logged, displayed, persisted into catch-up, or documented as share-safe.
* [ ] Isolation validation confirms real file, git, terminal, Docker, remote, Worker, hosted, inbound chat, and webhook execution remain unavailable and non-mutating.
* [ ] Stable docs and package README files consistently describe completed Phase 06 behavior and avoid hosted identity, analytics, production-hosted validation, remote execution, mobile certification, WCAG certification, public replay hosting, and trusted-erasure claims.

### Testing Requirements

* [ ] Focused protocol, Worker, web, server, CLI, and hook tests run and pass, or skips/blockers are documented with rationale.
* [ ] App desktop/mobile Playwright evidence runs for collaboration, local-only, unavailable, authority, remote context, reconnect, leave, isolation posture, and reduced-motion states where supported.
* [ ] Repository quality gates run: `npm run format:check`, `npm run lint`, `npm run typecheck --workspaces --if-present`, `npm test`, `npm run build --workspaces --if-present`, `npm run security:secrets`, `git diff --check`, and relevant media/browser gates.
* [ ] ASCII/LF validation passes for generated session artifacts and touched docs.
* [ ] Manual documentation review confirms PRD, UX PRD, phase PRD, stable docs, README files, and runbook language is consistent.

### Non-Functional Requirements

* [ ] Core FactionOS remains local-first with no dependency on Cloudflare, hosted auth, hosted storage, analytics, public replay hosting, Docker, remote runners, media providers, production-hosted deployments, or external transfer.
* [ ] Optional Worker federation remains compact, allowlisted, redacted, bounded, sender-aware, and documented as external transfer.
* [ ] Browser evidence remains scoped local browser evidence and does not claim formal certification or production-hosted validation.
* [ ] Hosted identity, trusted unified erasure, analytics, production-hosted validation, release cleanup, and legacy decommission remain tracked for Phase 07/08.

### Quality Gates

* [ ] All files ASCII-encoded.
* [ ] Unix LF line endings.
* [ ] Code and docs follow project conventions.

## 8. Implementation Notes

### Key Considerations

* This is a closeout and validation session. It should not add new product scope unless a validation blocker requires a narrow fix.
* Evidence should drive docs. Do not mark Phase 06 complete before command, browser, security, and docs evidence is recorded.
* The validation report should clearly distinguish local browser/mocked Worker evidence from hosted, mobile-device, or certification claims.
* Secret scan and privacy checks should account for docs and session artifacts, not just source code.
* Any command not run should be called out with a concrete reason and residual risk.

### Potential Challenges

* Gate duration: full repository tests, build, media gates, and browser evidence may be slow. Use focused runs first, then run repository gates where feasible and document any constrained validation explicitly.
* Stale docs: prior Phase 06 sessions may already updated many docs, so closeout should avoid churn and only correct stale status, evidence, or deferral language.
* Security posture ambiguity: room authority is stronger than hint-only metadata, but it is still not hosted account identity.
* Erasure ambiguity: leave/reset, browser storage cleanup, diagnostics cleanup, and CLI recovery remain narrower than trusted unified erasure.
* Browser evidence scope: desktop/mobile Playwright evidence is not physical-device mobile certification or WCAG certification.

### Relevant Considerations

* \[P05] **Unified erasure still missing**: Preserve trusted-erasure deferral for Worker storage, browser hints, archives, memory, settings, replay, exports, diagnostics, logs, backups, valid spool state, and future hosted surfaces.
* \[P03] **Real executors remain unimplemented by design**: Keep file, git, terminal, remote, Worker, container, and hosted execution unavailable unless a later approved threat model changes scope.
* \[P05-apps/warroom+apps/web] **War Room federation is optional and redacted**: Validate optional Worker room transfer without implying hosted collaboration or account proof.
* \[P00] **Hosted services are optional**: Core local workflows must keep working without hosted accounts, analytics, public tokens, or hosted storage.
* \[P05] **Redaction is boundary-specific**: Collaboration, Worker, diagnostics, replay, export, archive, adapter, backup, log, and future hosted-transfer payloads need separate minimization claims.
* \[P02-apps/web] **Responsive and accessibility debt**: Closeout evidence should be scoped and should not claim complete WCAG or mobile certification.
* \[P03] **Stable docs are the current contract**: PRD, UX PRD, stable docs, README files, and runbooks should be updated before Phase 06 is closed.
* \[P05-S07-HOSTED-IDENTITY] **Hosted identity remains open**: Non-hosted room-local authority does not prove account-backed identity.
* \[P05-S07-ERASURE] **Trusted erasure remains open**: Leave/reset and recovery flows are not unified deletion.
* \[P05-S07-HOSTED-VALIDATION] **Hosted validation remains open**: Local and mocked Worker evidence is not production-hosted validation.

***

## 9. Testing Strategy

### Unit Tests

* Run focused protocol, Worker, web, server, CLI, and hook tests covering authority, safe collaboration events, remote-context isolation, isolation diagnostics, unsupported routes, guarded-action unavailability, mobile/accessibility helpers, and compact diagnostics.
* Use repo-root `npm test` for broad Vitest regression coverage after focused runs pass.

### Integration Tests

* Run workspace typechecks with `npm run typecheck --workspaces --if-present`.
* Run `npm run build --workspaces --if-present` to catch package integration issues.
* Run `npm run format:check`, `npm run lint`, `npm run security:secrets`, `git diff --check`, and relevant media gates such as `npm run media:gates:check` and `npm run battlefield:check` if closeout touches media or browser evidence docs.

### Manual Testing

* Review retained Playwright screenshots and attachments for desktop/mobile collaboration, local-only, unavailable, authority, remote context, reconnect, leave/reset, isolation posture, and reduced-motion states.
* Review stable docs and README files for consistent status labels, evidence scope, blocked sensitive categories, no-execution boundaries, and Phase 07/08 handoffs.

### Edge Cases

* Missing Worker URL, invalid Worker URL, offline Worker, timeout, rate limit, malformed response, room full, room not found, stale decision, duplicate decision, non-leader decision, rejected join, socket failure, reconnect failure, catch-up unavailable, local server offline, auth-required, unsupported execution route, and guarded-action unavailable.
* Long participant names, room codes, safe labels, diagnostics messages, errors, mobile controls, and reduced-motion states.
* Non-ASCII characters, CRLF endings, broad local paths, secret-shaped values, raw prompts, command bodies, terminal output, diagnostics, exports, replay buffers, scan payloads, media drafts, logs, backups, and `EXAMPLES/` excerpts in generated artifacts.
