fix(platform): hide uninstalled app agents from assignee and mention pickers

[larryro]

Summary

• listAgents enumerated app-owned agents by scanning every bundle on disk under org/apps/, including uploaded-but-never-installed private apps.
• Switched to listAppInstallationsInternal (the appInstallations DB table) so only installed apps contribute agents to the task assignee picker and comment @-mention picker.
• Clarified listInstalledAppSlugsFromDisk doc comment: disk bundles ≠ installed apps.

Closes #2564

Test plan

• convex/agents/file_actions.test.ts — listAgents lists app agents only for installed apps; returns none when nothing is installed
• convex/apps/install_mutations.test.ts — listAppInstallationsInternal returns only slugs with an appInstallations row
• Manual: upload a private app without installing → agents absent from assignee/@-mention pickers; install → appear; uninstall → gone

Definition of done

• Green gate — regression tests pass locally (file_actions.test.ts 23/23)
• Security gate — no boundary changes; read-only query swap
• Tests — handler unit tests + query integration test added
• Migration — N/A (no schema change)
• Locales — N/A (backend-only)
• Docs — N/A (internal behaviour fix)
• Accessibility — N/A (no UI changes)
• Sweep — workflows/file_actions.ts still uses disk scan for automations list (out of scope per issue)
• Observed — unit tests verify installed-only enumeration
• Commits — single atomic conventional commit on desk branch

Desk reviewer grade — #2564

Code verdict: Approve — the fix correctly addresses the reported bug.

What works

• Root cause confirmed: listAgents used listInstalledAppSlugsFromDisk, listing every bundle under org/apps/ including uploaded-but-never-installed private apps.
• Fix is minimal and reuses the authoritative signal: listAppInstallationsInternal (appInstallations rows), already used by builtin_sync.ts.
• Picker data path confirmed: useActorDirectory → useListAgents → api.agents.file_actions.listAgents feeds assignee and @-mention pickers.
• Uninstall case covered: private bundles remain on disk, but DB row deletion correctly hides agents.
• Doc comment on listInstalledAppSlugsFromDisk clarifies disk bundles ≠ installed apps.

Tests

bunx vitest --run --project server convex/agents/file_actions.test.ts → 23/23 passed. Regression tests lock the listAppInstallationsInternal query swap.

Nits (non-blocking):

• issue-desk-qa/ exclusion assertion is tautological with current mocks.
• listAppInstallationsInternal does not filter uninstalling: true rows.
• Commit includes Co-authored-by: (repo discourages).

Desk reviewer grade — #2564 (rework 1/3)

Code verdict: Approve — the fix correctly addresses the reported bug. No code changes since prior review (db1a3de98).

What works

• Root cause confirmed: listAgents used listInstalledAppSlugsFromDisk, listing every bundle under org/apps/ including uploaded-but-never-installed private apps.

Tests

bunx vitest --run --project server convex/agents/file_actions.test.ts -t "listAgents app scope" → 2/2 passed (23/23 full file). Regression tests lock the listAppInstallationsInternal query swap.

Nits (non-blocking, unchanged from prior review):

• issue-desk-qa/ exclusion assertion is tautological with current mocks — stub a second on-disk-only bundle to make the negative case meaningful.
• listAppInstallationsInternal does not filter uninstalling: true rows (agents may linger briefly mid-uninstall; same pattern as builtin_sync.ts).
• Commit includes Co-authored-by: (repo discourages).

Automated review rounds

• Round 1 (adversarial): Correctness, security/boundaries, reuse, tests, blast radius — no blocking code defects.
• Round 2 (confirmation): CI failures reproduced; confirmed unrelated to four-file backend diff. Main Build also fails Validate images; #2579 documents repo-wide ModulesTooLarge regression on main.
• Bugbot / security-review: Could not compute branch diff in harness; manual read covered same axes. No security issues.

Desk reviewer grade — #2564 (rework 2/3)

Code verdict: Approve — fix is correct and complete; rework 2 addresses the prior test nit.

What works

• Root cause fixed: listAgents no longer calls listInstalledAppSlugsFromDisk (every bundle under org/apps/). It now queries listAppInstallationsInternal, the authoritative appInstallations signal — same pattern as builtin_sync.ts.
• Picker path confirmed: useActorDirectory → useListAgents → api.agents.file_actions.listAgents feeds both the task Assignee picker and comment @-mention picker.
• Uninstall case covered: private bundles remain on disk after uninstall, but DB row deletion correctly hides agents.
• Doc comment clarified: listInstalledAppSlugsFromDisk now documents disk bundles ≠ installed apps; hub listing still uses disk scan as intended.
• Rework 2 test improvement: file_actions.test.ts now simulates an on-disk-only issue-desk-qa bundle and asserts readdir is never called for it when only issue-desk is installed — the negative case is no longer tautological.

Tests

bunx vitest --run --project server convex/agents/file_actions.test.ts -t "listAgents app scope" → 2/2 passed.

Automated review rounds

• Round 1 (adversarial): Correctness ✓ — query swap fixes uploaded-but-uninstalled leak and post-uninstall disk retention. Security/boundaries ✓ — requireOrgMembershipById still gates the action; internal query uses the same organizationId. Reuse ✓ — no divergent install signal. Tests ✓ — handler + query regression. Blast radius swept ✓ — workflows/file_actions.ts disk scan acknowledged out of scope.
• Round 2 (confirmation): Bugbot/security-review harness could not compute branch diff; manual read covered same axes. CI failures reproduced and confirmed unrelated to the four-file backend diff.
• Non-blocking nits: listAppInstallationsInternal does not filter uninstalling: true rows (agents may linger briefly mid-uninstall; same as builtin_sync.ts). Commits include Co-authored-by: (repo discourages).

Absorbed into #2674 (merged with a semantic conflict resolution onto the automations-renamed module: installations-query-based listing, test mocks updated) — plus the same installed-only fix applied to the workflows surface, which had the identical uploaded-bundle bug. #2674 closes #2564's parent class; recommend closing this PR.

[larryro]

Closing as superseded: absorbed into #2674 (merged 2026-07-12), which also applied the same installed-only fix on the workflows surface. See Yannick's comment above.
