WalkthroughThe change adds deleted-session window reconciliation across the window manager, session manager, and daemon. It removes matching windows and history, retries failed cleanup, preserves tombstones until reconciliation succeeds, and enables parallel global migration tests.

| Filename | Overview |
|---|---|
| internal/session/manager_delete.go | Invokes window reconciliation after catalog deletion commits and retains a tombstone when reconciliation must be retried. |
| internal/session/manager_delete_reconciliation.go | Implements bounded retry scheduling, cancellation, and worker shutdown for pending deleted-session window reconciliation. |
| internal/session/manager_delete_tombstone.go | Extends staged and committed tombstone recovery to reconcile session windows before removing durable deletion state. |
| internal/daemon/window_manager_session_reconciler.go | Adapts the profile window-manager registry to session deletion, including readiness and terminal absence classification. |
| internal/windowmanager/session_delete_reconciliation.go | Adds the internal lifecycle operation that removes windows associated with a deleted session. |
| docs/qa/reports/2026-08-25-eng-140-delete-session.md | Records successful focused HTTP and UDS verification but confirms that the required full verification gate remains incomplete. |

| - **Native tools:** No `compozy__*` tool IDs, toolsets, descriptors, schemas, digests, risk flags, diagnostics, or capability gates changed; the existing window command path is reused. | ||
| - **Extensibility and hooks:** No extension, registry, skill, resource, MCP, bridge, or `config.toml` surface changed. The existing `window.close` hook path remains observable, including after startup retry readiness. | ||
| - **Workspace data isolation:** The changed datum is a workspace/profile-scoped window aggregate. Session deletion passes the stored profile and workspace ids; the adapter resolves that profile and the reducer targets only the owning workspace. Tests cover another workspace and unrelated session/app identities. | ||
| - **Official Compozy skill:** No public tool id, CLI path, hook event, capability, extension resource, or memory/network/task semantic changed; `skills/compozy/` was checked and needs no update. |

When this runtime change is handed off without a passing make gate-full, the repository-wide build, lint, test, code-generation, and boundary checks remain unsatisfied, so the PR does not meet its required merge gate.

Make both retry tests deterministic. The retry starts after 250 ms, and each attempt can run for up to 5 seconds. The 4-second tombstone deadline depends on scheduler and I/O timing. The restart test also asserts exactly one call while the retry goroutine remains active. Use a test-controlled retry gate, or accept firstCalls.Load() >= 1 and stop retries before asserting the count.

Limit retries to transient reconciliation failures.
cleanupDeleteTombstones schedules retries for every parseable cleanup error. The retry worker repeats every non-context error until shutdown, including metadata ID and owner mismatches. Schedule only errDeletedSessionWindowReconciliationPending errors, and stop the worker when a retry returns a non-transient error.

Issue
ENG-140 — deleting a session must also close every desktop window that belongs to that session.
Root cause
Session deletion removed the session catalog and filesystem state, but it had no runtime seam into the profile/workspace window-manager stream. Window-manager state therefore retained matching windows, closed entries, focus references, and undo/redo snapshots after the session was gone. The existing public close command also rejects pinned windows, so replaying normal close commands could not satisfy the deletion contract.
Implementation
WindowReconcilerseam and injected the daemon-owned profile window-manager registry into the session manager.App == "session"andInstanceKey == sessionIDmatches from every placement in the owning workspace, including tiled, floating, stacked, minimized, pinned, cross-desktop, and closed-entry state.Tests and verification
