+
+Manual conclusion:
+
+`BACKLOG_MASTER.md` is the current active backlog, while archived roadmaps preserve older planning detail. The correct next step is a recovery/merge PR that imports still-relevant archived planning into the active backlog rather than creating a competing backlog file.

+# PR_26180_OWNER_002 Product Backlog Discovery Report
+
+Generated: 2026-06-28
+
+## Executive Summary
+
+The repository currently has an authoritative active product backlog:
+
+`dev/build/ProjectInstructions/backlog/BACKLOG_MASTER.md`
+
+That file explicitly states that the backlog is the authoritative source for determining the next logical PRs. Active Project Instructions reinforce that decision through:
+
+- `dev/build/ProjectInstructions/addendums/team_backlog_sod_eod_standard.md`
+- `dev/build/ProjectInstructions/addendums/build_path_sync.md`
+- `dev/build/ProjectInstructions/addendums/status_model.md`
+- `dev/build/ProjectInstructions/team_assignments/team_ownership.md`
+- `dev/build/ProjectInstructions/TEAM_START_COMMANDS.md`
+
+Before the governance reorganization, the backlog function existed mainly as roadmap documents under the old `docs_build/dev/roadmaps/` structure. Those files still exist under:
+
+`dev/archive/legacy-docs-build/roadmaps/`
+
+The old roadmaps were not deleted. They were archived. However, some detailed product and platform planning in those roadmaps has not been fully merged into the active `BACKLOG_MASTER.md`. No information appears physically lost from the repository, but some roadmap detail is no longer active backlog material unless Owner intentionally recovers it.
+
+Recommended strategy: keep `BACKLOG_MASTER.md` as the single active backlog and run a follow-up governance PR to merge still-relevant planning details from archived roadmaps, database planning files, and tool UAT documents into `BACKLOG_MASTER.md` or linked subordinate backlog sections. Do not create a competing `PROJECT_BACKLOG.md`.
+
+## Determinations
+
+1. Did a canonical backlog previously exist?
+   - Yes. Before the reorganization, roadmap-style canonical planning existed under `docs_build/dev/roadmaps/`, now archived under `dev/archive/legacy-docs-build/roadmaps/`.
+
+2. What file(s) contained it?
+   - `MASTER_ROADMAP_ENGINE.md`
+   - `MASTER_ROADMAP_FEATURES.md`
+   - `MASTER_ROADMAP_TOOLS.md`
+   - `MIDI_STUDIO_V2_ROADMAP.md`
+   - `POST_MIGRATION_PLATFORM_ROADMAP.md`
+   - `MASTER_ROADMAP_SAMPLES2TOOLS.md`
+   - `MASTER_ROADMAP_STYLE.md`
+   - `MASTER_ROADMAP_RECOVERY.md`
+   - Level 8 roadmap append/update files
+   - `phases.txt`
+
+3. Is it still present?
+   - Yes. The files are present in `dev/archive/legacy-docs-build/roadmaps/`.
+
+4. Was it renamed?
+   - Not as a direct file rename. The active source-of-truth role was replaced by `dev/build/ProjectInstructions/backlog/BACKLOG_MASTER.md`, while legacy roadmaps were archived.
+
+5. Was it split into multiple files?
+   - Yes. Current backlog governance is split across active backlog, team ownership, team assignment, status model, and Build Path sync documents.
+
+6. Was it accidentally abandoned during repository reorganization?
+   - Partially. The active backlog was preserved as `BACKLOG_MASTER.md`, but some detailed roadmap content is only archived and not fully represented in the active backlog.
+
+7. What currently serves as the backlog?
+   - `dev/build/ProjectInstructions/backlog/BACKLOG_MASTER.md`
+
+8. What information appears to have been lost, if any?
+   - No tracked files appear lost. Potentially stranded details include the old tool rebuild sequence, detailed MIDI Studio V2 remaining work, platform roadmap phases, and old engine/toolchain roadmap status details.

+## Recommendation
+
+Use this authoritative backlog strategy:
+
+Merge existing planning documents into the current `BACKLOG_MASTER.md` model.
+
+Do not create a new `PROJECT_BACKLOG.md` because `BACKLOG_MASTER.md` is already named by active Project Instructions as the source of truth. A new competing backlog file would create another governance surface.
+
+Recommended follow-up PR:
+
+`PR_26180_OWNER_003-backlog-recovery-and-roadmap-merge`
+
+Suggested scope:
+
+1. Keep `BACKLOG_MASTER.md` as the active backlog SSoT.
+2. Audit archived roadmaps for still-relevant unchecked or in-progress items.
+3. Merge selected details from:
+   - `MASTER_ROADMAP_TOOLS.md`
+   - `MIDI_STUDIO_V2_ROADMAP.md`
+   - `POST_MIGRATION_PLATFORM_ROADMAP.md`
+   - relevant `MASTER_ROADMAP_ENGINE.md` open items
+4. Add links from active backlog items to per-tool UAT docs where useful.
+5. Mark stale active operations docs that still mention `docs_build/dev/roadmaps/` as superseded or archive-only.
+6. Preserve archived roadmaps as historical reference, not active backlog authority.
