It finalized the action record and disposition tracking for historical findings, copied artifacts, ignored media intake, generated drafts, sensitive evidence, archived spec material, and `docs/PROGRESS.md`, while preserving stable replacements and fail-closed wording in the tracked docs. No destructive cleanup, archive move, or media promotion was approved beyond the recorded retain, blocked, and unavailable outcomes. The session remained documentation- and evidence-only and kept raw sensitive historical content out of stable tracked output. *** ## Deliverables ### Files Created | File | Purpose | Lines | | -------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------- | ----- | | `.spec_system/specs/phase08-session07-legacy-evidence-decommission-and-media-release-gate/IMPLEMENTATION_SUMMARY.md` | Final session closeout summary and Phase 08 handoff record | \~90 | ### Files Modified | File | Changes | | ------------------------------------------------------------------------------------------------------------------ | ----------------------------------------------------------------------------------------------------------- | | `.spec_system/PRD/phase_08/legacy_decommission_media_release_gate.md` | Finalized candidate dispositions, stable replacement references, rollback notes, and residual-risk handoff. | | `.spec_system/PRD/phase_08/decommission_approval_matrix.md` | Converted the session 07 matrix from candidate-only tracking to final-review dispositions. | | `.spec_system/PRD/phase_08/phase08_requirement_routing_matrix.md` | Updated session routing and handoff wording for Session 07 evidence and Session 08 closeout ownership. | | `.spec_system/PRD/phase_08/phase08_release_risk_matrix.md` | Aligned residual risk wording with the final Session 07 disposition set. | | `.spec_system/PRD/phase_08/PRD_phase_08.md` | Marked Session 07 complete and updated the phase progress tracker. | | `.spec_system/PRD/PRD.md` | Updated the master PRD status map for the Phase 08 Session 07 release gate. | | `.spec_system/state.json` | Cleared the active session pointer and recorded the session completion history. | | `.spec_system/specs/phase08-session07-legacy-evidence-decommission-and-media-release-gate/spec.md` | Marked the session spec complete. | | `.spec_system/specs/phase08-session07-legacy-evidence-decommission-and-media-release-gate/implementation-notes.md` | Captured the session progress log and final disposition notes. | | `package.json` | Bumped the repository patch version. | | `docs/legacy-consolidation.md` | Recorded stable replacement coverage for legacy findings and reports. | | `docs/api/event-api-hook-contracts.md` | Refreshed preserved contract notes for historical findings and routing boundaries. | | `docs/media-assets.md` | Recorded media release-gate boundaries and blocked promotion cases. | | `docs/release.md` | Updated release-gate wording, cleanup rules, and Session 08 handoff language. | | `docs/privacy-and-security.md` | Updated sensitive-output, retained evidence, and hosted no-claim wording. | | `docs/hosted-services.md` | Updated hosted boundary wording for the release gate handoff. | | `docs/environments.md` | Updated environment notes for retained evidence and secret-safe handling. | | `public-demo/docs_public-demo/validation.md` | Updated public-demo validation wording for cache and media-gate boundaries. | | `README.md` | Refreshed release-facing legacy evidence guidance. | | `apps/web/README_web.md` | Refreshed web-facing release boundary guidance. | *** ## Technical Decisions 1. **Fail closed on uncertain evidence**: paths without stable replacement coverage were retained, blocked, or marked unavailable instead of being deleted. 2. **Preserve conclusions, not raw evidence**: stable docs record path-level dispositions, counts, and outcomes without copying sensitive prompts, payloads, or historical content. 3. **Keep Session 08 separation explicit**: Session 07 closes the media and legacy decommission gate, while Session 08 remains the final release-candidate closeout owner. *** ## Test Results | Metric | Value | | -------- | --------------------- | | Tests | 8 verification checks | | Passed | 8 | | Coverage | N/A | Passed checks: * `npm run media:gates:check` * `npm run media:check` * `npm run media:visual:check` * `npm run media:demo:check` * `npm run media:drafts:check` * `npm run battlefield:check` * `npm run security:secrets` * `git diff --check` ASCII and LF scans also passed for the changed session artifacts. Focused tests or Biome checks were not required because no scripts, tests, media config, or runtime code changed. *** ## Lessons Learned 1. Release-gate cleanup is safest when the stable replacement doc is written before any disposition is finalized. 2. Sanitized evidence keeps the phase useful for handoff without turning it into an archive of raw historical output. *** ## Future Considerations 1. Session 08 should use the Session 07 action record and handoff wording as its starting point for final release-candidate closeout. 2. Any later decommission or archive decision should reuse the same preserve- before-action and fail-closed rules. *** ## Session Statistics * **Tasks**: 21 completed * **Files Created**: 1 * **Files Modified**: 16 * **Tests Added**: 0 * **Blockers**: 0 resolved --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://faction-os.gitbook.io/faction-os-docs/.spec_system/archive/sessions/phase08-session07-legacy-evidence-decommission-and-media-release-gate/implementation_summary.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
