Summary\n\nBounded S1 continuation of #515 for non-destructive desktop filesystem I/O-error recovery.\n\n- Adds an explicit startup failure kind so filesystem I/O failures receive a truthful retry action.\n- Keeps preserve-first quarantine restricted to classified filesystem corruption.\n- Keeps IndexedDB reset restricted to generic IndexedDB storage failures.\n- Adds native recovery copy for the five production locales and regenerates runtime bundles.\n\nThis is a fresh bounded PR based on the authoritative main after merged #542/#544 work. It does not redesign Storage-Core, modify #542 or #543, or include S2, onboarding, PWA, or roadmap work.\n\nReferences: #515, #542, #543.

Summary by CodeRabbit

  • New Features

    • Added clearer startup error messages for project storage and file-access issues.

    • Recovery options now vary by issue type: retry for temporary access problems, quarantine for corruption, and reset for eligible storage failures.
  • Bug Fixes

    • Prevented destructive recovery actions from appearing when they are not appropriate.
  • Documentation

    • Updated project metrics to reflect 2,939 translation keys and 7,320+ tests.

Summary

This PR successfully implements non-destructive desktop filesystem I/O-error recovery by adding explicit failure kind differentiation. The implementation correctly separates three failure scenarios:

  • Storage failures (generic IndexedDB issues) → Reset option
  • Project corruption (filesystem) → Quarantine option
  • Project I/O errors (temporary filesystem access issues) → Retry option (non-destructive)

The policy logic in startupRecoveryPolicy.ts correctly constrains destructive actions to their appropriate contexts, ensuring filesystem I/O failures never trigger database resets and generic filesystem errors never gain quarantine authority. The recovery flow properly preserves user data by defaulting to non-destructive retry for transient I/O failures.

All changes are well-tested with comprehensive coverage of the new failure scenarios.

Review Change Stack

📝 Walkthrough

Walkthrough

Startup recovery now classifies storage, corrupt-project, and project-I/O failures. The UI shows type-specific messages and actions, including retry for project-I/O failures. Reset and quarantine actions remain restricted to their applicable failure types.

Changes

Startup recovery

Layer / File(s) Summary
Failure classification and recovery policy
services/startupRecoveryPolicy.ts
Recovery actions now include failureKind. Reset applies only to IndexedDB storage failures. Quarantine applies only to corrupt filesystem projects.
Failure-specific error screen
components/StorageErrorScreen.tsx
The screen selects localized messages and actions by failure kind. Project-I/O failures use retry and do not show destructive recovery actions.
Recovery flow wiring
services/startupRecovery.tsx
Startup recovery passes failure classifications to StorageErrorScreen and reloads the application for project-I/O retries.
Localized startup copy
locales/*/common.json, public/locales/*/bundle.json
All supported locales add project-I/O startup messages and retry labels.
Recovery behavior tests
tests/unit/StorageErrorScreen.test.tsx, tests/unit/startupRecovery.test.tsx, tests/unit/startupRecoveryPolicy.test.ts
Tests cover classifications, action restrictions, retry handling, and recovery states.
Project metrics documentation
README.md
README metrics now report 2,939 i18n keys and 7,320+ tests.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 21e08

The PR makes a bounded desktop recovery behavior change with no actionable merge-blocking risk remaining. One Spanish translation should be clarified to avoid ambiguity, and a small source-comment cleanup may be handled as follow-up.

Keep the second clause scoped to classification.

ni se ha modificado says that the project itself was not modified. The intended message is that the failure was not classified as modified. Use El proyecto no se ha clasificado como dañado ni como modificado.
