fix: resolve critical and major issues from code review (#145)

vscarpenter · claude · web-flow · commit 77fd87f35063 · 2026-02-25T18:23:03.000-06:00
* fix: resolve critical and major issues from code review

- Add dryRun support to bulkUpdateTasks (was silently mutating data)
- Separate deleted vs updated counts in bulk operation responses
- Fix fallback totalTasks using nullable instead of misleading pending counts
- Thread request Origin through auth middleware for correct CORS on errors
- Add environment parameter to CORS response helpers for dev-port support
- Optimize list-tasks cache to serve filtered queries from cached all-tasks
- Initialize encryption once per batch instead of per-task in decryption loop
- Fix import ordering in list-tasks.ts
- Bump version to 6.8.8

* fix: address minor code review issues across frontend, MCP server, and worker

Frontend:
- Use structured logObject for all log levels (not just error) in logger.ts
- Add 'email' to sensitive-key sanitization list for PII protection
- Fix import ordering in oauth-handshake/subscriber.ts
- Wrap error string in Error object in oauth-callback-handler.tsx
- Fix misleading "localStorage" log message (writes to sessionStorage)
- Fix indentation in pwa-register.tsx
- Clean up controllerchange listener and fallback timer in pwa-update-toast.tsx

MCP Server:
- Gate debug logs behind LOG_LEVEL env var in MCP logger
- Fix help text: 18 → 20 total tools, add missing tool listings
- Remove unsafe type cast for statsReset; use properly typed result object
- Fix Math.max(...spread) stack overflow risk; use reduce for large arrays
- Downgrade config guidance strings from ERROR to INFO level
- Add error context to sync-status catch for better diagnostics

Worker:
- Replace positional ALLOWED_ORIGINS[0]/[1] with named constants
- Fix double encodeURIComponent in buildErrorRedirect
- Add runtime type coercion for D1 query results (fixes pre-existing TS error)
- Downgrade pull processing log from INFO to DEBUG, remove vector clock noise
- Clean up informal "FIX #N" and "BULLETPROOF FIX" comment labels
