* feat(agent-launch): make a lost launch safe to retry `agent.launch` could not be retried safely. Only a create-worktree target carrying a clientMutationId got any idempotency at all, and that was a 60s in-memory cache with no caller partition that dies with the process; an existing-workspace launch got none. Mobile retries a lost create by design, so the retry is the ordinary case — and a retry past that cache meant a second worktree and a second agent. A caller may now name its launch with an optional `operationId` and get one execution, the recorded answer on every replay, and a truthful refusal when the outcome is unknown. Admission runs before the worktree selector is resolved, so a replay answers from the record rather than re-deciding against today's world. The core is an atomic claim. Admission alone cannot decide who runs: two replays both read `pending`, and settling `unknown` replaces the outcome blind, so two serialized writes are not a compare-and-swap and both callers execute. A conditional current-state swap now reports which caller won, and settlement is monotone so a late `unknown` cannot erase a recorded success. Also here: a host-computed fingerprint over the launch intent that excludes mutable settings, the full launch result persisted so a replay returns the receipt and warning that cannot be recomputed once settings move, and a derived child operation id for the inner attach — the ledger key carries no method, so forwarding the launch id would make the attach conflict with its own launch. Safety, not recovery. Nothing here probes for a surface a dead attempt left behind, adopts one, or finishes an interrupted publication. Callers that send no `operationId` keep today's behaviour exactly, which is why the field is optional and the host advertises `agent.launch.replay.v1`: an older host strips an unknown param and launches anyway, so a client may only treat a retry as safe once the host has said it enforces the ledger. * fix(agent-launch): keep an unreadable launch payload from costing the store Review follow-ups on the replay-safety ledger. A recorded `launch` payload must not gate row validity. `isAgentLaunchResult` is a hand-maintained mirror of a result type later work will edit, and `isAgentSessionOperationRow` is consulted by the store loader, where one rejected row makes the whole file unparseable — a primary and backup that both fail to parse raise `agent_session_store_corrupt` and the profile loses every lease. That is the same argument the row already makes for keeping `sessionId` required, applied to the field this PR added. The payload is now typed `unknown`, left out of the row guard, and narrowed where it is read, so a payload this build cannot read refuses exactly one replay. A recorded failure now replays as the code the launch raised. Narrowing it through the closed `agentSession.*` refusal list answered `worktree_not_found` with `agent_session_operation_invalid` — the ledger's "your id is malformed" signal, which invites a client to mint a fresh id when the truthful answer is that this launch definitively did not run and the same id is safe to retry. The persisted failure code is bounded on the way in. A code is an identifier, but `error.message` is free text: an errno sentence carrying an absolute path arrived here as one and was written into a file re-serialized whole on every later operation. Bounded on write only — a length check in the row validator would reject rows this same build wrote, which is the hazard above. Comments: the caller key does not give one client a single namespace across surfaces, because the structured attach this launch performs partitions under `structuredCallerFor`; the two coincide only for a bearer-identity caller with no paired device, which is exactly when the derived child id is load-bearing. Recorded as a known limit that a `lost` claim cannot tell a sibling executing now from one a restart abandoned; telling them apart needs execution-generation tagging, which is recovery. Tests: the store-level ablation was inert — it defined a local stand-in and passed identically with and without the guard. It now substitutes the non-atomic composition into the handler's own store and watches one tap create two workspaces. Each of the four new guards was watched failing against the unfixed code: `agent_session_store_corrupt` on reopen, `expected false to be true` on the row guard, `agent_session_operation_invalid` in place of `worktree_not_found`, and a 6042-character code where 128 is the bound. * fix(agent-launch): keep live retries in one execution * docs(agent-launch): clarify failed replay guidance
