Summary

• Remove the nightshift orchestrator (internal/nightshift, CLI verb, worker prompts, skill) and the /work drain skill.
• Remove everything that only existed to feed it: the dashboard cockpit view, 🌙 moon launcher and task-selection dots, the /api/nightshift* routes and dedicated-clone logic, the git-derived task status (DEVBRAIN_TODO_DERIVE_GIT), the fixed-set fence (DEVBRAIN_TODO_ONLY), the approve and note verbs and the approved field, the turn-marker hook, the nightshift-only session classifier rules and cwd/worktree heuristics, internal/procutil, and the nightshift branch from the pre-push gate.
• gitx is trimmed to the runner heartbeat uses. /continue, /distill, the queue, and the Typed/Bot toggle (still driven by harness-meta turns) are unchanged.
• README, docs/architecture.md, CI comment, goreleaser, and the surviving skills drop nightshift. The README GIF is refilmed as a Board → Profile tour (2.08 MB, ~15s).

Net: 109 files, −12.2k lines.

Goldens

testdata/golden is hand-edited only where the removed behavior changed output: the two worker-session prompts in the dashboard fixture are now classified by text (command/human) instead of nightshift, the approved key is gone from todos.json, and the todo CLI golden drops the note/approve steps (task 0003 therefore stays held).

Test plan

• scripts/test-guard.sh (full suite, guarded) green
• go test -race -count=3 on dashboard, todo, hooks, gitx
• both Node dashboard regressions pass
• GIF refilmed from the rebuilt binary and eyeballed frame-by-frame

CLAUDE (Fable 5.1): Cross-model review ran (Opus 5.5, high effort, $1.14, local one-shot via the review wrapper). Disposition of its findings, fixed in fix: keep legacy worker-session detection and prune retired skills:

• Historical fleet data reclassified as typed (Medium ×2) — valid. Restored the classifier's autonomous_*/nightshift_prefixes rules, the importer's /nightshift/·/drain/·-wN path detection, and the live hook's matching rule, all marked as legacy. Old logs and a re-import keep their auto: true rows; the prompt goldens are back to their original values.
• Stale work/nightshift skill dirs survive an upgrade (Medium) — valid. migrate now removes them from both skill roots; covered in TestInstall….
• Legacy ~/.claude/nightshift + shim cleanup dropped (Low) — restored.
• Env-scrub test vacuous (Low) — valid; it now asserts the task file landed under the harness project.
• .gitignore .nightshift/ (Note) — restored with a legacy comment.
• Unrelated gofmt churn, mis-indented listener (Notes) — reverted / fixed.
• clearSel() ReferenceError (High) — not a bug: the Profile IIFE defines its own clearSel.
• Dead turn-marker Stop hook on existing installs (High) — not a bug: hookSpecs never registered a Stop hook in settings.json; the orchestrator set NIGHTSHIFT_MARKER only in worker worktrees. Nothing calls devbrain hook turn-marker.
• --without nightshift now errors (Medium) — intended hard break, hence 1.6.0.
• .card{position:relative} (Low) — only the select dot was absolutely positioned inside a card; nothing else depends on it.
