fix(project): stage saves before atomic publication

[seonghobae]

Advances #962 with bounded crash-safe project publication, native filesystem trust-boundary repair, target-scoped interrupted-replacement recovery, and executable Tauri command-path coverage.

Exact current identity

• Protected base: develop@749511c3ad4000090048718f685c6bee6b3d2c25.
• Branch: fix/project-save-atomic-publication-962.
• Exact current head: 9b7e3e90c03d775b2cc1181d6aaac2a66c8f1223.
• Open, non-draft, unmerged into develop. Predecessor-head evidence never transfers to the merge gate.

Dependency-root consolidation

The crash-recovery work formerly carried by stacked PR #1061 was a strict descendant of this branch and was consolidated into this canonical dependency-root owner without force-push. Protected develop did not move as part of that consolidation.

Implemented publication boundary

Project bytes are bounded, staged beside the selected destination, fully written, and sync_all()'d before publication. Parent-chain symlink/reparse redirection is rejected before staging, with only the documented exact macOS /etc, /tmp, and /var root aliases admitted when they resolve to their canonical /private/... directories.

For a destination absent at the authority snapshot, publication uses a hard link when available and otherwise an OS-native no-replace rename: Linux renameat2(RENAME_NOREPLACE), macOS renamex_np(RENAME_EXCL), and Windows MoveFileExW without replacement. A concurrently appearing target is preserved.

For an existing regular destination, the publisher captures native target identity before staging and conditions replacement on that identity. Linux/macOS atomically exchange the staged inode and target; Windows uses ReplaceFileW with a unique same-directory backup. A target-scoped prepared journal is written and synced before replacement. Interrupted recovery accepts only the expected candidate/displaced identities, restores a displaced predecessor or concurrent winner when required, syncs the directory, and retires state only after safe cleanup. Stale prepared journals with no owned recovery artifacts are retired without treating unrelated current target bytes as recovery-owned.

Project loading remains bounded to MAX_PROJECT_FILE_BYTES + 1 and uses no-follow/native identity checks around handle acquisition. Windows identity is volume serial number plus file index from GetFileInformationByHandle. Recovery journals have a dedicated 64 KiB bounded no-follow read and deterministic target-scoped names.

TDD / review repair chain

Representative dependency-root repairs retained in this branch include:

• no-follow open authority: RED bb4a827d705490aacedf26da141fff1a8da96067 → FIX bae6de7f74d7387361ebe003ef0e3e4322eb86ba;
• existing-project re-save: RED d70a2521d4af137406b22130ec4f232963b24603 → FIX 54d8966ee6734f7d6305c8bf7d503c1721a37840;
• hard-link-free first-save crash window: RED 4eddf73b61484170bfe19aedde9be8235c8a5d23 → native no-replace FIX 16c68adc1975ae1b94ffa1adf8da8d57b7dd228c;
• Windows native identity: RED 106da93f5daaca3d086c9c1004e89f23ff99c5b7 → FIX 723b34b35a0644f8e08d9a3f344302a7d6acce09;
• existing-target identity swap: RED f1b486d589f9a6f093a9c09d6e757b305e264f23 → native identity/conditional replacement FIX 3d7b0a4795bde0723aaa8a9cffcf384800e1940e;
• stale-journal retirement + owned-stage cleanup: RED 6fbedb8b9418787c44efb3fe8c401372b7b35da5 → FIX 817cb56e4f8caf46fe76423b4160ad790d0957ca;
• final-path placeholder regression guard strengthened on the canonical branch so both direct and borrowed File::create_new(target) forms are rejected while staging remains allowed;
• executable Tauri persistence-command coverage replaces the former source-text-only wiring evidence: c232896… exercises real save/load handlers through Tauri IPC, 2707221… proves per-app persistence state isolation, and exact head 9b7e3e90… adds invalid Tauri payload coverage.

Fresh current-head inline review-thread inventory has zero unresolved threads. The earlier concern that source-text wiring checks were not equivalent to Tauri command behavior is therefore no longer an unimplemented bound: the current branch now executes the actual persistence handlers through a Tauri mock runtime.

Exact-head verification state

On exact head 9b7e3e90c03d775b2cc1181d6aaac2a66c8f1223, the materialized deterministic repository gates are terminal-success for ordinary CI/build/Rust, the focused Windows persistence suite, Windows/macOS builds, coverage evidence/source-tree checks, dependency review, security audit, SBOM, release preflight, OSV, the required lower-case Scorecard gate, Trivy FS, PR-queue scan, Semgrep, CodeQL JavaScript/TypeScript and Python, secret scan, Bandit, and supply-chain inventory. Skipped/manual/neutral results are not counted as success. The separate GitHub Advanced Security Scorecard advisory is neutral, not a passing gate.

Three central required lanes remain non-passing on this unchanged exact head and therefore block merge:

• opencode-review run 33277449501, job 99169171696: fail-closed because no authenticated APPROVED or CHANGES_REQUESTED OpenCode verdict is bound to exact head 9b7e3e90…. The required status check itself is not a review.
• noema-review run 33277449505, job 99166589344: trusted source materialization, repository-scoped cwl-noema-review App credential, visibility resolution, and provider-secret checks succeed; the expected oversized local-ingress 413 request_too_large contract probe is followed by live OpenRouter ZDR selection, then the trusted sidecar exits before /healthz with review sidecar preflight failed. The Noema review step never runs and no current-head verdict exists. This failure class is owned by the central batched route-preflight lane .github#1415; there is no BandScope-local causal repair.
• strix run 33277449503, job 99167266572: trusted target/base materialization and workflow contract smoke succeed; the shared sidecar reaches /healthz and provider-route preflight after 12 seconds, then the bounded OpenAI-compatible gateway preflight receives zero bytes for 30.002 seconds and times out. Strix itself never executes and no authoritative vulnerability verdict exists. This post-healthz gateway/fallback failure is already routed to central owner .github#1399; timeout/synthetic/skipped evidence is not accepted.

Remaining product/architecture bounds

This slice does not claim global startup recovery scanning, known-good backup rotation, descriptor-bound ancestor authority across concurrent parent replacement, cross-process writer serialization, public schema/version migration, or exhaustive power-loss/fault-injection coverage. Those are distinct architecture/product bounds rather than evidence that the implemented exact-target publication path should bypass its current merge gates.

Merge gate

Do not merge until one unchanged exact head has focused/full Tauri tests plus every applicable repository and central CI/build/release/security/SAST/SBOM/supply-chain/coverage/review gate terminal-success, exact required owned coverage/docstrings, zero valid unresolved findings, a qualifying independent non-author approval, and ordinary protected-branch acceptance without bypass.

Queued, pending, skipped-required, cancelled, absent, neutral, failed, stale, predecessor-head, protected-base, status-only, model-only, rate-limited, self/author, or synthetic evidence is not success.

Merge Risk: 🟡 Moderate · up to 86b97

This PR stages and synchronizes project data before atomic or no-replace publication and adds target-scoped recovery, reducing partial-write and overwrite risk. Merge readiness remains moderate because concurrent ancestor replacement could redirect later file operations, a crash could leave an unmanaged duplicate artifact, and required exact-head validation is not yet complete.

Please review exact current head 1883196956b975b2e724f268fd7e574c12d14699 only. The new TDD pair is RED 070f4cdbcb994a60057e3a2f8b911bc51dc5d9ca → production fix 1883196956b975b2e724f268fd7e574c12d14699: no adjacent target-scoped recovery journal means no mutation, so recover_project_publication now returns before the strict parent-chain mutation policy; actual journal recovery still requires the strict safe parent chain, and final-component read authority remains no-follow/native-identity checked. The required OpenCode job 99137123588 failed closed only because a current-head formal verdict was absent. Do not inherit any predecessor-head verdict or test evidence.

@opencode-agent review

Please perform the required independent formal review on exact current head 817cb56e4f8caf46fe76423b4160ad790d0957ca only, against freshly resolved protected develop@749511c3ad4000090048718f685c6bee6b3d2c25. Apply current repository/central guidance and superpowers:using-superpowers.

Revalidate the latest TDD repair specifically: RED 6fbedb8b9418787c44efb3fe8c401372b7b35da5 → production fix 817cb56e4f8caf46fe76423b4160ad790d0957ca, where recovery now retires a stale target-scoped journal without overwriting an independently changed target when both journal artifacts are gone, and Linux/macOS/Windows replacement paths clean BandScope-owned staging files when identity or journal preparation fails. Also verify that the previously integrated no-replace first-save, existing-target native identity/rollback, bounded no-follow read, Windows native identity, and recovery-journal contracts remain intact.

Treat the three remaining unresolved informational review threads as hypotheses to assess against current code rather than inherited defects: recovery is target-reselection scoped rather than a startup-wide scanner; ancestor-directory authority remains path-based rather than descriptor-bound under concurrent parent replacement; and the Tauri route guard tests currently use source-text assertions. If any is a current release-blocking defect within #970 ownership, post CHANGES_REQUESTED with the first causal production boundary and smallest realistic RED regression. Otherwise post an authenticated current-head APPROVED verdict. Do not transfer predecessor-head review/check evidence and do not mutate the branch as part of this independent review.

Apply current repository and central guidance and do not transfer predecessor-head evidence.

Revalidate the existing staged/no-replace publication, existing-target native identity and rollback, bounded no-follow read, Windows native identity, target-scoped recovery, and the latest test-only guard hardening in apps/desktop/src-tauri/tests/project_persistence_atomic_publication.rs, which now rejects both File::create_new(target) and File::create_new(&target) final-path reservation spellings while still allowing staging via &stage. The broader source-text wiring-test limitation and descriptor-bound parent-authority limitation remain explicit unresolved bounds; do not treat this guard hardening as resolving them.

Post an authenticated current-head APPROVED or CHANGES_REQUESTED verdict. If changes are required, identify the first causal production boundary and smallest realistic regression. Do not mutate the branch as part of the independent review.

Revalidate the canonical persistence boundary plus the newly integrated versioned project-file envelope: bounded/no-follow load and native no-replace first publication; identity-conditioned existing-target replacement; durable target-scoped recovery including stale-journal retirement and completed-rollback cleanup; Windows native file identity and permission hardening; executable Tauri IPC persistence tests; v1 projectFormatVersion decoding with explicit future-version rejection before strict v1 decode; legacy raw-song compatibility; and the finite-positive optional tempo contract aligned with the shared frontend validator. The two current Devin informational threads on future-version handling and tempo alignment were verified against this exact source and are now resolved. The required opencode-review job 99188632237 failed closed only because no authenticated APPROVED or CHANGES_REQUESTED OpenCode verdict was bound to this exact head.
