[DEV-99] View devintern worker logs directly in the dashboard via a Logs tab

[danii1]

Task: DEV-99

Summary: View devintern worker logs directly in the dashboard via a Logs tab

Implementation Details

Context is clear. Now let me check a couple more patterns before implementing:
All context gathered. Now implementing:
The first draft has several flaws (broken ANSI pattern, unsafe unbounded read in the tail path, confused timestamp fallback). Rewriting the module cleanly:
Fixing three bugs in that file (fd ordering, misplaced import, literal escape characters):
Shell escaping made this worse. Fixing deterministically with python:
Three fixes needed: space-before-timezone offsets, iterate task-key matches past stop-list, shorter Bearer threshold:
Backend API layer next:
Now the handleLogs handler at the end of the file:
Now wire the route in dashboard-server.ts:
Frontend now. First the API types in dashboard-ui:
Pure view helpers + tests:
Now the LogsView component:
Now the App shell — third tab and route:
Backend test file for worker-logs:
That test draft had two sloppy spots (a convoluted assertion and a fake permission test). Rewriting cleanly with a deterministic directory-as-file trick instead of chmod:
Workspace deps missing — installing first:
Curious — isolated eval passes now. Re-running the actual test suites to see if the failure reproduces:
Found it: fractional seconds are consumed by the regex but never appended to the normalized string. Fixing with explicit groups:
Tests pass. Adding endpoint-level cases to dashboard-api.test.ts:
Now appending the logs tests to dashboard-api.test.ts:
Backend green. Now the UI package tests and typecheck:
UI green. Docs next:
All warnings are pre-existing in untouched code. Typecheck + build:
All 986 tests green across the monorepo. Final verification: rebuild formats and confirm the code package bundles:
End-to-end smoke test of the real server with the built UI:
DEV-99 is implemented and fully verified. Summary of the change:

Backend (@getdevintern/code)

• src/lib/worker-logs.ts (new): bounded file-tail reader over worker.stdout.log / worker.stderr.log (the paths worker init's launchd config writes). Reads only ~256 KiB from each file's end via positional reads, snaps to a line boundary, strips ANSI escapes, parses optional ISO timestamps, classifies severity (explicit ❌/ERROR/⚠ markers win over stderr-default), masks credential-shaped content before serving, extracts Jira-style task keys (with a stop-list for SHA-/CVE- style false positives), weaves stdout+stderr round-robin when untimed and true-merges by timestamp when every line carries one.
• src/lib/dashboard-api.ts: new getWorkerLogs() on DashboardData (searches the working dir plus the workspace home so standalone devintern dashboard still finds the daemon's files) and enriches entries with their latest matching run (runId, runStatus) via the existing run store; new validated handleLogs handler (limit 1–1000, level all/info/warn/error).
• src/dashboard-server.ts: serves GET /api/logs.

Frontend (@devintern/dashboard-ui)

• Third Logs tab at shareable #/logs; auto-refreshing via the shared usePoll (pauses on hidden tabs), server-side level filter, client-side search with a live error/warning count, follow-tail scrolling with "↓ Jump to latest" when you scroll up, level dots + stderr badges, per-entry task chip linking to #/runs/:id, and graceful empty states (no capture files yet / no matches / fetch error) plus a truncation & unreadable-source footnote.

Verification

• New tests: tests/worker-logs.test.ts (parsing + tailing incl. byte-window truncation, stream interleave, unreadable-source handling), logs cases in tests/dashboard-api.test.ts (validation, empty state, redaction + run linkage, HTTP end-to-end), log-view.test.ts in the UI package.
• Full monorepo: format ✓ lint ✓ typecheck ✓ 986 tests pass ✓ CLI bundle builds with the updated UI ✓
• Docs updated: docs/code/dashboard.md (Logs tab, log sources/redaction/bounds, API table) and a troubleshooting row in docs/code/worker.md.
