An export can exhaust storage while writing its recovery intent or staging file. Exercise those failures inside the installed ZIP executable through the bundled production export service: inject ENOSPC after real partial journal/staging writes and during staging sync, then require byte-identical Library/output trees, unchanged Head, no Receipt, no busy operation and no pending recovery after a cold service reopen.

A separate synthetic Library and existing external target isolate these scenarios from the five golden projections. Restore the filesystem boundary and retry the export; require durable publication, exactly one Receipt with the actual output hash, a new Head and clean recovery. The original golden Library remains byte-identical. Fixed diagnostics contain no private paths or content.

Validation: 25 targeted export/archive tests, types, lint, format, contract schemas, main build and packaged discovery (24 tests) pass. The two full proof unit tests now have a bounded 30-second budget for the additional durable write/reopen scenarios; native deadlines and assertions are unchanged. No local native app or e2e execution. Windows/macOS installed execution requires GitHub CI.

This proves handling of an injected filesystem ENOSPC, not physical volume exhaustion or native Save dialog interaction. Part of #40; the remaining native release gates stay open.

Summary by CodeRabbit

  • Reliability
    • When an export encounters insufficient disk space, existing files and project data remain unchanged, and no incomplete receipt or pending work is left behind.
    • After disk space is available, retrying the export saves the expected data and records a durable receipt.
    • Export integrity remains consistent through failures during setup and writing, while source project data stays unchanged. These checks cover multiple points where a disk-space failure can occur.

📝 Walkthrough

Walkthrough

The packaged export proof now injects ENOSPC during journal creation, staging writes, and staging sync. It checks recovery and state preservation after each failure, then retries the export and verifies the saved output, receipt, and project revision. Packaged tests use a shared installed-process runner with sanitized failure diagnostics.

Packaged export proof

Layer / File(s) Summary
Disk failure injection and recovery
apps/desktop/src/main/packaged-export-disk-proof.ts, apps/desktop/src/main/packaged-export-proof.ts, apps/desktop/src/main/index.ts
The proof injects ENOSPC at three filesystem operations. After each failure, it checks recovery, project state, output bytes, receipts, and proof hashes. The proof runner accepts an option to include or skip disk-failure checks.
Durable retry and proof test expectations
apps/desktop/src/main/packaged-export-disk-proof.ts, apps/desktop/src/main/packaged-export-proof.ts, tests/export-proof.test.ts, tests/archive-proof.test.ts
The proof retries the export and checks the saved JSON, receipt hash, revision change, and recovery state. Tests expect three refusals and a durable retry. The archive and export proof tests specify a 30-second timeout.
Installed-process execution and diagnostics
tests/support/installed-export-process.ts, tests/installed-export-diagnostics.test.ts, tests/packaged/archives.spec.ts, tests/packaged/exports.spec.ts
Packaged archive and export tests use a shared process runner with configured timeouts and a 16-KiB output limit. Failure diagnostics report duration and validated process status without including captured messages or output. The Windows export test timeout is 540 seconds.

Windows current-head run 37806846560 job 113413250070 passed all three ENOSPC preservation scenarios. Both installed export/archive commands then failed after preserved_staging_sync; 20 other packaged tests passed and two platform-specific tests skipped. The captured error does not distinguish the 120-second host deadline from retry publication/reopen failure.

Add fixed elapsed stage markers for retry service open, Save, target selection, publication, Library reopen, output verification and recovery. A bounded fixed-category failure code excludes raw error text. The host command wrapper reports only numeric exit status, allowlisted signal, killed flag and elapsed time while preserving the original error. This distinguishes budget exhaustion from an actual retry/reopen fault. The root cause remains unestablished; no environment, timeout or semantic assertion is changed.

Three targeted proof/diagnostic tests, types/lint/format/main build and 24-test discovery pass. Native execution remains GitHub CI only. Latest diagnostic changes still require clean CodeRabbit review and native CI before merge.

@coderabbitai Fixed the Minor finding in the new head: Playwright now receives a fresh Error containing only allowlisted numeric process status and bounded exact fixed stage lines. No raw child error message, command path, stdout, stderr or cause is retained. The real Node child-process regression failed before the fix and passes now; it exits 7 with private command/output values, verifies those values are absent, retains the fixed retry_saving stage, rejects an arbitrary stage name and checks that cause/stderr properties are absent. The narrow lint suppression documents why preserving the original cause would defeat redaction.

Two diagnostic tests plus types/lint/format pass. Native deadlines and assertions remain unchanged; Windows retry diagnosis is still pending current CI. Please verify this fix against the new head and resolve the thread if satisfied.

@qisoft Verified the fix at head 1efb63f and resolved the Minor review thread.

  • The runner throws a fresh Error without raw child-process details or cause.
  • Stage diagnostics accept only exact allowlisted names and bounded numeric durations.
  • The regression test checks the real rejection path, private-value redaction, and retained retry_saving stage.

Verification was source inspection only. I did not run tests. Windows retry diagnosis remains pending CI.

Windows 1efb63f run 37818765254 job 113454086372 confirms the failing seam: both installed export/archive children were killed by the 120-second host command deadline (duration_ms=120083/120064, killed=true, SIGTERM). The disk proof continued to make progress: journal-write preservation completed after 46-48 seconds, staging-write preservation after 69-72 seconds. The current attempt did not reach retry before termination. All other 20 packaged tests passed; two platform-specific tests skipped.

Avoid running the new disk-failure scenarios redundantly in the archive proof: archive mode still generates all five golden projections and checks existing refusal/cancellation boundaries, then runs its import/hostile corpus. Export mode retains all three disk-failure scenarios, cold reopens, unchanged-tree assertions and durable retry. Give that expanded Windows export command a bounded 300-second budget (540-second enclosing test); archive/macOS command budgets remain 120 seconds. This adjusts the test orchestration budget based on measured progress, not a production timeout or assertion. Restricted OS-only environments and every semantic assertion are retained.

Four local proof/diagnostic tests, types/lint/format/main build and discovery pass. No local native app launch. Revised native execution must pass GitHub CI before this is called fixed; latest changes also require CodeRabbit review.
