Reviewer's GuideThis successor PR carries forward filesystem admission while adding canonical lossless schema classification, non-destructive legacy handling, source-aware serialized write fencing across project and auxiliary stores, and a separate desktop editing boundary that prevents readable legacy projects from entering Redux; recovery and backup paths now report unsupported inputs explicitly.

This PR successfully implements the filesystem admission controls described in #553, addressing the two P1 correctness findings from #654. The implementation correctly prevents:
- ID-less legacy project inspections from creating ambiguous shared fallback write authority that could block unrelated CURRENT projects
- LEGACY_UNVERSIONED filesystem projects from crossing into the editable Redux store where edits would be lost on restart
The changes are well-structured with appropriate error handling, admission boundaries, and write authority validation. The new loadProjectForEditing method provides the necessary separation between readable legacy projections and editable state, while the write authority checks prevent concurrent access conflicts.
You can now have the agent implement changes and create commits directly on your pull request's source branch. Simply comment with /q followed by your request in natural language to ask the agent to make changes.

348-374: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚖️ Poor tradeoffConsider moving the legacy write-authority suite into its own spec file.
This block adds about 370 lines to a file that already exceeds 1,900 lines. The legacy fencing, ID-less admission, and queued-authority tests form one cohesive group. A dedicated file such as
tests/unit/services/fs/fsLegacyWriteAuthority.test.tswould keep each file inside the target size and shorten failure triage. The sharedmakeFakeFshelper and thelegacyBinderNodefixture can move to a small test helper module so both files reuse them.As per coding guidelines: "Target files between 200 and 700 lines; split files over 700 lines into hooks, subcomponents, selectors, or tests rather than using comment-only sections."

Summary\n\nThis successor PR supersedes frozen PR #654 for the #553 filesystem-admission slice.\n\nIt carries forward the final reviewed semantic state of #654 and closes the two valid late P1 correctness findings:\n\n- background inspection of an ID-less legacy project no longer installs ambiguous shared fallback write authority that can block an unrelated CURRENT project;\n- a readable LEGACY_UNVERSIONED filesystem project cannot cross the ordinary editable desktop bootstrap boundary into Redux, where edits would otherwise appear successful but be lost on restart.\n\n## Supersession / provenance\n\n- Predecessor: #654, frozen head .\n- #654 reached the absolute 15-commit ceiling before the two late P1 findings arrived.\n- #657 implemented the corrected #625 governance contract and advanced \ to ; #654 consequently became conflicting.\n- This branch starts from that current green .\n- The predecessor net diff was transferred as one signed carry-forward commit; the two P1 corrections are one additional signed commit.\n- No #654 history was rewritten, amended, force-pushed, or given an over-absolute exception.\n- #654 remains historical review evidence and will be cross-linked as superseded only after this successor is established.\n\n## Validation\n\n- Focused filesystem/bootstrap/backup/project-store tests: 137 passed.\n- Startup recovery/policy tests: 12 passed.\n- Biome on changed files and : passed.\n- [ERR_PNPM_NO_SCRIPT] Missing script: ci:prepush\
Command "ci:prepush" not found. Did you mean "pnpm run ci:prepush"?: passed.\n- Pre-push signing and local admission checks: passed.\n- Local PR-size evidence: 21 files, 1,260 meaningful lines, 2 commits; below the absolute 30/3000/15 ceiling. The hard-tier advisory is expected and no exception is used.\n\n## Intentionally deferred #553 scope\n\nThis PR does not implement durable legacy migration, raw-carrier writeback, source-generation/CAS fencing, a general read-only editor, R15 encrypted desktop storage, queue redesign, or unrelated maintainability cleanup. Those remain follow-up #553 work.

Summary by cubic
Converges filesystem project admission so schema classification never rewrites source data, and legacy projects become read-only instead of appearing editable. Also fixes two late correctness findings: ID-less legacy inspections no longer claim ambiguous fallback write authority over unrelated projects, and readable legacy projects can no longer cross the desktop bootstrap boundary into Redux.
loadProjectForEditingpath that rejects legacy projects before Redux hydration.Written for commit 9435f13. Summary will update on new commits.
