Add Custom Actions support with periodic sync and UI integration - #42
Conversation
Introduce shared menu and settings surfaces for defining and running reusable actions, with Firebase-backed sync and execution output sheets.
Queue pending upserts and deletions for retry, initialize cloud data per UID, and route menu actions through scoped notifications.

Merge Risk: ⚪ Minimal · up to Custom action data is now kept separate per account, concurrent edits during sync are preserved, and account changes in Settings switch the sync session. No unresolved merge-blocking risk remains in the reviewed changes. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Custom actions can run with the application's local user permissions. The execution checks provide meaningful protection, but duplicating a trusted action can authorize a different executable path without reviewing that path. Exploitation requires a particular configuration and subsequent user invocation; synchronization alone does not execute actions. Retained concerns

Review comments at @macgit/Services/CustomActionStore.swift:
- Around line 89-98: Update the local action catalog and pending mutations used
by CustomActionStore so they are stored and loaded per UID before syncing
through cloudStore; prevent actions or pending edits from one account being
uploaded to another. If guest data is transferred to an account, require
explicit opt-in for both actions and pending edits.
- Line 99: Update `applyRemote` to preserve locally pending upserts and exclude
pending deletions when merging remote actions. In the cloud upsert completion
path, remove a pending ID only if the current action still matches the uploaded
action, preserving edits made during the await.
- Line 99: Update CustomActionStore’s updateCloudSession and syncNow to track a
session-generation token, capture it when a sync starts, and discard remote
results if the generation changed before applyRemote. When a superseded sync
exits, trigger a sync for the current session so it does not wait for the
periodic timer.
Review comments at @macgit/Views/Common/CustomActionsSettingsView.swift:
- Around line 113-115: In the Locate flow, keep the executable override update
through store.setExecutableOverride but remove the immediate store.trust call.
Leave the action untrusted so the row offers Review afterward.

Fixed in a6436fa:
DeepSeek executor findings 1 and 2 are not reproduced by full source: output writes/reads already use outputLock, resume is idempotent, cancel does not wait for an unstarted process, and cancellation is rechecked after launch. Repository path confinement is not an execution sandbox for explicitly trusted arbitrary scripts, so that recommendation was not applied. Validation: macOS xcodebuild build succeeded; git diff --check passed. Regression tests added but not executed, per project instruction to build without running the app/tests. Runtime UI remains unverified. |

Addressed the outside-diff lifecycle finding from review 5406744783 in 41e9a25. CustomActionStore now owns an app-lifetime subscription to account state and Settings Sync eligibility, registered during app initialization. UID/eligibility changes synchronously switch the catalog and invalidate the old sync session before scheduling cloud work. Session updates no longer depend on Welcome or repository windows being open. The inline executable-override thread is also fixed and resolved. macOS build and git diff --check passed; XCTest and runtime interaction were not run per repository instructions. |
