fix(storage): make worktree cleanup work and show why it skipped

[maria-rcks]

Storage cleanup skipped worktrees containing ignored files such as .env, and Settings gave no useful explanation. Cleanup now supports three local-change policies, a guarded Delete now action, and live reports with recovered bytes, per-item sizes, and failure or skip reasons. Runs share the automatic cleanup worker and never overlap; worktree removal remains unforced to protect tracked edits.

The storage page uses standard settings rows: Delete now has a short last-run summary and an outline action button. Last run uses the existing settings fold, starting closed, with removed/kept/failed counts, one settings row per result, removal sizes, and failures in red. All pre-existing Storage rows and descriptions remain identical to main. The only new UI is the Keep worktrees with local changes select and the Cleanup section. Settings remain machine-scoped with project overrides.

Size measurement runs before final thread, session, git, and policy revalidation, so activity during the scan cancels removal. A deterministic real-git regression reproduced removal before the fix and verifies the checkout and its untracked file survive afterward. All 54 cleanup tests, scoped server lint, and server typecheck passed on Blacksmith. This removes the added scan interval; the pre-existing gap between final checks and removal remains. The follow-up provider/client recheck is unverified because the preview automation host disconnected before a provider turn could start.

Verification: web typecheck, scoped lint, and 75 existing settings tests passed on Blacksmith. In the real isolated web client, Delete now removed an 8 MB worktree, retained edited and untracked worktrees, and reported a locked-worktree failure. Details open/close, tooltip details, light/dark themes, and a 600 px viewport were checked; uploaded recording playback and seeking were verified. Native desktop, native mobile, remote/tunnel connections, multiple environments, and lists past 200 entries are unverified in this pass.

Retention-hint and fold follow-up (7533cc6aa8): web typecheck and scoped lint passed with exit 0; all 60 settings-search tests passed with exit 0 on Blacksmith. Visual verification completed in the isolated web client using the authorized headless Playwright fallback after preview-host retries failed. At 1440 × 1000 (2×), retention hints, the closed/open Last run fold, light/dark themes, an 80 MB cleanup run, and a locked-worktree failure were exercised. The media below has been replaced with evidence from c67ca66.

Before

After

Captured at c67ca66 through the server-side preview tools. All three day rules and Delete unchanged worktrees are enabled. The manual run recovered 80 MB and retained modified and untracked files. Uploaded playback and seeking were verified.

This UI pass: web typecheck, scoped lint, and all 60 settings-search tests passed on Blacksmith. Real isolated web runs recovered 80 MB, kept modified and untracked worktrees, and reported a locked-worktree failure. No-rule disabling, dialog open/close, light/dark themes, and uploaded video playback and seeking were verified. Native clients, remote/tunnel connections, multiple environments, and permission-denied sessions were not exercised in this pass.

UI pass by gpt-6-astra in the Codex harness through T3 Code.

Scope and approval

This change addresses the existing storage-cleanup capability requested by Maria: cleanup policies, manual execution, and readable results in Settings. The author, maria-rcks, is listed in the trusted upstream triage exemptions. This exemption covers contribution triage; maintainers still review the behavior before merging.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This change adds production storage-cleanup controls and RPCs, including a manual deletion workflow and detailed reports. It also changes the default worktree policy so ignored files such as .env and build output may be deleted during cleanup, requiring human review.

📝 Walkthrough

Walkthrough

Storage cleanup adds selectable worktree retention policies and reports for automatic and manual runs. WebSocket RPCs expose manual cleanup and report streaming. Storage settings display reports, allow manual runs, and let users configure worktree retention.

Changes

Storage Cleanup

Layer / File(s)	Summary
Retention policy and report contracts packages/contracts/src/settings.ts, packages/contracts/src/settings.test.ts, packages/shared/src/projectSettings.ts, packages/shared/src/projectSettings.test.ts, packages/shared/src/serverSettings.ts, packages/shared/src/serverSettings.test.ts, apps/web/src/components/settings/scopedSettings.test.ts	Worktree cleanup settings add worktreeKeepWhen, defaulting to "uncommitted-changes". Shared settings resolution carries this value through resolved and custom rules. Contracts define cleanup report entries and report metadata.
Cleanup decisions and run reports apps/server/src/storageCleanup.ts, apps/server/src/storageCleanup.test.ts, apps/server/src/server.ts	The cleanup service evaluates retention rules, records kept, removed, and failed outcomes, and publishes reports capped at 200 entries. Manual runs return a report; automatic runs continue through the worker. Tests cover retention policies, report behavior, file cleanup, and failures.
RPC access and runtime wiring packages/contracts/src/rpc.ts, packages/contracts/src/environment.ts, packages/contracts/src/clientRpcPermissions.ts, packages/client-runtime/src/rpc/client.ts, packages/client-runtime/src/state/server.ts, packages/client-runtime/src/state/commandPermissions.test.ts, apps/server/src/auth/RpcAuthorization.ts, apps/server/src/auth/RpcAuthorization.test.ts, apps/server/src/environment/ServerEnvironment.ts, apps/server/src/observability/RpcInstrumentation.ts, apps/server/src/ws.ts	The server exposes cleanup and report-stream RPCs. The client runtime adds the command and subscription. Cleanup requires settings-write scope; report retrieval uses orchestration-read scope.
Storage settings and guidance apps/web/src/components/settings/StorageSettings.tsx, apps/web/src/components/settings/settingsSearch.ts, docs/user/project-settings.md, apps/web/src/lib/formatBytes.ts, apps/web/src/components/settings/ResourceTelemetryDiagnostics.tsx	The settings UI shows cleanup reports, enables manual runs when cleanup rules and environment permissions allow them, and offers three worktree retention policies. Search entries and documentation describe the controls. Byte formatting is shared with the resource telemetry diagnostics component.

Merge Risk: 🟡 Moderate · up to eb55e

With the "Edited tracked files" policy, cleanup can permanently delete untracked files from a worktree whose removal then fails, for example because the worktree is locked. Resolve this before merging. The remaining settings issues are minor accessibility and usability problems.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to eb55e

Deletion remains permission-controlled and protects tracked edits, active work, and unmanaged checkouts. However, the more aggressive policy can delete local files before worktree removal fails, leaving a partially modified checkout without reporting that partial deletion. Existing cleanup settings also adopt a policy that permits removal of ignored files.

Retained concerns

• Medium · reliability · observed: Under tracked-changes, cleanup permanently deletes untracked and ignored files before attempting non-forced worktree removal. If removal then fails, the checkout survives but its local files do not. The failure report has no partial-deletion indication or byte accounting, impairing recovery decisions. The real-Git regression explicitly asserts this state for a late tracked edit. The base had no separate git-clean phase; tracked-edit preservation and explicit policy warnings do not make this new two-step transition atomic.

Security review details

Security Blast Radius

• inferred — A settings-write-authorized caller can request a policy-governed sweep across eligible worktrees, expired browser artifacts, and rotated logs within one connected server environment. The web action can initiate independent sweeps across multiple authorized connections. Exposure is not limited to one thread, but no arbitrary-path deletion input was found in the new RPC.

Security Findings and Attack Paths

• observed — The supported adverse outcome requires the aggressive tracked-changes policy and an eligible worktree: git clean deletes local files, then a late tracked edit makes removal fail. The test confirms the tracked edit survives while the untracked file is lost. This is a destructive failure-state issue, not evidence that a read-only client can invoke cleanup.

Trust Boundaries and Controls

• observed — Server-side authorization rejects orchestration-read-only manual cleanup before handler execution. Deletion additionally checks shared ownership, active work, terminals, provider sessions, managed roots, linked-worktree identity, branch and commit stability, and policy stability.
• observed — Cleanup reports transport full worktree paths to orchestration-read-authorized clients despite basename-only UI presentation. Worktree paths already appeared in shell contracts authorized by the same read scope at the merge base. Path visibility alone therefore does not establish a new authorization violation; report-specific sensitivity requirements were not supplied.

Resilience and Maintainability Implications

• observed — Once a manual request is queued, worker ownership is independent of the waiting RPC caller; interrupting that caller does not remove its queued sweep. Worker-scope closure interrupts processing and drops queued items, while completed reports are memory-only. These are lifecycle facts, not established cancellation-contract violations.

Hardening Proposals

• proposed — Make partial destructive progress explicit in the report contract and recovery behavior. Consider a reversible staging strategy for local files before worktree removal, with restoration on refusal, and define whether accepted manual jobs survive caller disconnection. These are design proposals rather than existing controls.

`cleanupGit` so untracked and ignored files are not irreversibly deleted before
worktree removal succeeds. Stage the files selected for cleanup outside the
worktree, remove the worktree, then delete the staged files on success and
restore them if removal fails; if rollback cannot be implemented, skip `git
