* feat(agent-session): let the host own a chat's tab id and let a create reserve it

A structured chat's tab id was derived from its session id by every layer that
needed one: the renderer, the host snapshot and the status address each built
their own spelling. The join between a conversation and the tab that shows it
must be a pointer the host owns, not a derivation each client repeats.

The session record now carries surfaceTabId. A create pins it: the tab half of
the pane agent.launch reserved, an optional tabId on agentSession.create, or a
host-minted UUID. Records written before the field existed are backfilled at
open with the string clients derived, in memory at once and on disk with the
store's first transaction, so nothing keyed by it (read state, notification
ids, worker rows) moves on upgrade. A second record under a held id is refused.

Only the record and the two create wires change here. The snapshot still
publishes agent-session:<sid> and the renderer still derives its local id;
those move in the next two changes. agentSession.create is a strict object, so
the field is advertised as a capability a client checks before sending it.

* fix(agent-session): record the derived tab id for an unreserved create

A create that reserved no tab minted a random UUID that no reader uses: the
renderer, status address, worker rows and host-shared read state all still key
by structured-agent-session-<sid>. Persisted, that id would move every chat
created before readers switch to the recorded one, orphaning its read state
and worker rows the way the backfill exists to prevent. An unreserved create
now records the derived id, the same rule the backfill applies, so the record
always matches the prefix every existing key uses; an opaque mint belongs with
the change that moves the last reader.

Also:
- a chat tab id must be a host tab id on the record, the create wire and in
  admission, matching what agent.launch already requires of paneKey; a
  web-surface id would decode as another tab
- the stored launch-result guard checks the structured outcome's tabId
- comments no longer claim a retry naming another tab conflicts; replay keys
  on the attach fingerprint and answers with the recorded id (now pinned)
- the wire refusal test used a non-hex digest, so the schema refused it for
  that reason; it now reaches the tab id rule
- pin that the reload path refills the id without forcing a save

* test(agent-session): correct the tab-id fingerprint comment to match replay

Brennan BensonandMerge Sim 1ae7aa8bb4 feat(native-chat): resume an Agent Session History row into a new structured chat (#19176)
* feat(native-chat): resume an Agent Session History row into a new structured chat

A Claude or Codex row in Agent Session History gains "Resume in New Chat": it
opens a new structured native-chat tab that continues that provider
conversation, with the prior turns already in the journal. Until now those rows
could only be resumed into a PTY terminal; the structured branch could reveal a
chat Orca already owned but could not adopt one it had never held.

Almost all of the machinery existed. Both lanes already resume from the record's
provider handle chain, the journal already has a transcript importer, and the
handle chain already models `adopted` as an origin. The gap was that a create
always minted an empty chain, so the adapters started a fresh conversation. This
seeds that chain.

The client names only the conversation. `agentSession.create` is reachable by
paired mobile clients, so the transcript path and the account home are derived
by the executing host and validated against the account homes it recognises —
a client-supplied path would choose which file the host imports and which
credential directory the provider child launches against.

Failure refuses rather than degrades. A transcript that cannot be found refuses
before anything is created; one that fails or decodes empty *after* the provider
has resumed fails the attach, tearing the child down and publishing no tab,
because an empty journal beside a context-carrying agent claims a continuity the
provider never gave.

Codex can resume into any workspace since it is handed the rollout path; Claude
resolves transcripts under a project key derived from the launch cwd, so it is
offered only for the workspace the conversation was recorded in.

* fix(native-chat): widen adopted-home discovery and keep ordinary launches untouched

Three corrections from review of the first commit.

The adoption's account-home candidates now include the extra Codex homes session
discovery already scans. A row this host listed could otherwise refuse to
resume, which reads as the feature being broken rather than as a scope.

Ordinary launches call `createStructuredAgentSessionLaunchIntent` with two
arguments again. Passing the resume source unconditionally appended a trailing
`undefined` that four existing call-site assertions had to absorb; the churn was
the caller's fault, not the tests'.

The transactional adoption guard's comment claimed the self-exemption is what
lets a committed create replay. It is not: replay is settled earlier by the
operation ledger, and an adoption always arrives with a null expected fence, so
a request naming an existing session id is refused a few lines below either way.
The exemption is part of what "another record" means, and the comment now says
that instead.

* fix: preserve history adoption through create and retries

* fix: replay committed history adoption from durable identity

* fix: validate history before claiming adopted sessions

* fix: extract AI vault resume domains

* fix: recognize typed history resume refusals
