Four defects and two follow-ups from the delta review. The `worktree rm` refusal was a dead end in the desktop UI. Its message matched no matcher in `classifyWorktreeForceDeleteReason`, and an ordinary desktop delete already passes `force=true` for the dirty-file skip, so classification returned null unconditionally: the toast showed raw CLI wording with no Force Delete button, and a user with a live chat session was stuck unless they knew to reach for the CLI. That is the #11960 shape `shared/worktree/removal.ts` documents, so the refusal now has its own prefix, matcher, `WorktreeForceDeleteReason` and toast copy, classified BEFORE the `force` guard and nulled once the waiver is spent — exactly how `unstopped-pty` is handled, with matcher and hint kept in the same file as that contract requires. The copy says Force Delete will close a running conversation rather than borrowing the "could not confirm" wording, because Orca watched these sessions stay attached; there is no doubt to waive. Structured `terminal read` cursors were unsound and are now refused. The PTY cursor indexes an append-only completed-line buffer with a monotone count; a session journal is a BOUNDED tail re-projected on every read, so a saved index addressed different lines as the journal grew — and `truncated` could never fire to say so, because it tests `cursor < oldestCursor` and `oldestCursor` was always 0. A poller got wrong or duplicated lines under `truncated:false`. Separately, a streaming turn's lines counted as completed with `partialLine` hardcoded empty, so a mid-turn cursor consumed a half-written line whose growth was never redelivered — the `"hel"`/`"hello"` hazard the PTY reader guards against. The journal does have stable item identity, but `terminal.read`'s cursor is a number on the wire and cannot carry it, so a cursor read now refuses and names `worker-read --source transcript`, which already has that contract including `source_changed`. No cursor space is advertised either: `nextCursor` is null and the cursor fields are absent, rather than claiming an index the next read cannot honour. The header claim that all four fields kept their meanings was true of the shape and false of the invariants; it now says which ones hold. Two fixes had no test at their real seam, which is the same failure that produced this whole set — the runtime tested directly, the seam tested by neither. The group-addressing test hand-composed the recipient list itself, so deleting the composition at the call site left it green; it now drives `sendGroupMessage` with no PTY terminals at all. Nothing referenced `isLiveStructuredAgent`, so the `dispatch --inject` fix had no red-then-green at all; it now has one driving `RuntimeTerminalAgentPresence.isRunning`. Both were ablated and confirmed red. Folder-workspace removals sweep and kill PTYs without `requirePhysicalStop`, so the structured sweep no-opped there and left a live session bound to a workspace about to be forgotten. They now close best-effort under an explicit `closeStructuredSessions` flag, kept separate from `requirePhysicalStop` because the two questions differ: that one asks whether a stop must be PROVEN before files are touched, and it is what licenses a refusal. These paths do not refuse — the root is shared so no checkout vanishes under the child, and one of them is a never-throw forget a refusal would wedge. Reconciliation sweeps set neither and still close nothing. Also: the force close is raced against the same sweep deadline every PTY surface is bounded by, so a wedged provider close reports the timeout instead of hanging `worktree rm --force` forever; and the refusal now prints a count and the providers instead of raw session ids, which our own marker rationale treats as one tab-id hop from a credential.
