refactor(mobile): migrate the small domains onto RpcOperation (step 4) (#20705)

* refactor(mobile): pin each RPC golden to its own mount adapter, not every domain's

`recorderSha256` covered the whole recorder directory, mount adapters included, so a domain PR
that adds its adapter module moved the header of all 153 goldens. #20568 did exactly that and its
merge with main conflicted on that one line in 153 files; every future domain PR would collide
with every other in flight the same way.

Split the directory at a real seam instead of a filename convention: `adapters/` holds one module
per domain, registered in `adapters/mounted-operation-modules.ts`, and `recorderSha256` now covers
the engine only. A new `adapterSha256` covers the source of the module that mounts each operation
a golden's scenarios drive, read off the same `mounts` calls that build the table the recording
runs against, so the pin cannot name a file the runner did not use.

Adding a domain's module now re-digests nothing already recorded; editing one fails exactly the
goldens mounted through it. `adapter-seam.test.ts` keeps the split from drifting: an engine file
inside `adapters/`, an adapter defined in an engine file, a register entry naming the wrong file,
and an adapter importing a sibling each fail.

The five adapters that were inline in `pilot-mount-adapters.ts` move into their own modules, which
leaves that file as the registry and nothing else. `GOLDEN_FORMAT_VERSION` goes to 5 for the new
header field; the goldens re-record in the next commit.

* test(mobile): re-record the RPC goldens under the split recorder/adapter digest

Header-only. Every changed line is `recorderSha256` (the engine digest no longer covers
`adapters/`), the new `adapterSha256`, or `goldenFormatVersion` 4 -> 5; `baseline` is unchanged and
recording ran against the same pinned product tree.

    git diff -U0 -- mobile/rpc-foundation/goldens | grep -E '^[+-]' \
      | grep -vE '^(\+\+\+|---)' \
      | grep -vE '^[+-]  "(recorderSha256|adapterSha256|goldenFormatVersion)":' | wc -l
    0

The seven `adapterSha256` values partition the 153 goldens by the module each was recorded
through: 58 settings, 37 hosted review, 21 source control, 11 new-tab agents, 9 file inventory,
9 tasks, 8 workspace settings.

* refactor(mobile): stop pinning goldens to recorder inputs no recording can read

The adapter split left three per-domain edits still moving all 153 headers: the mutant table, the
per-family mutant registry beside it, and the probe-hole witness. None can change a recording --
the loader consults a mutant only when a mutant test asks for one, and no suite but the two
recording drivers writes a golden -- so pinning them claimed a provenance the goldens do not have
and charged every domain a full re-record for it.

`mutants/` now holds the table, the registry, the reference states, the mutant suites and the
probe-hole witness, and `recorderSha256` skips it. What makes that sound is that no recording can
reach it: `operationModuleLoader` takes a resolved mutation spec instead of importing a table by
name, so nothing on the recording path names `mutants/` at all. `mutants/mutant-seam.test.ts`
checks exactly that, and fails if an engine file names the directory or anything outside imports
from it.

`recorderSha256` also pins only the suites in `recording-drivers.ts`, which
`scripts/rpc-recording.mts` records from, so the two cannot drift. A suite that reads goldens, or
writes one to a scratch directory, is no longer provenance for a recorded file.

`OPERATION_EXPOSURES` went the other way, because it does change what a recording loads: withhold
the resume-metadata exposure and exactly four goldens fail. Each domain module now declares its own
exposures and gets its own loader, so `adapterSha256` pins the ones that reached each golden.

Two assertions in the digest boundary test were vacuous: `join(root, '.')` normalises back to
`root` and hit `recorderSha256`'s per-root cache, so the prose-is-ignored claim never recomputed
anything. Each call now spells the root differently.

* test(mobile): re-record the RPC goldens under the mutant and driver exclusions

Header-only, and no format bump: the header shape is unchanged. `recorderSha256` moves on all 153
because the engine set shrank, and `adapterSha256` moves on the 58 settings goldens because that
module now carries its own exposure declaration.

    git diff -U0 HEAD~1 -- mobile/rpc-foundation/goldens | grep -E '^[+-]' \
      | grep -vE '^(\+\+\+|---)' \
      | grep -vE '^[+-]  "(recorderSha256|adapterSha256)":' | wc -l

* fix(mobile): restore the preferences actions the merge resolution dropped

#20568 added `resume` and `trust` actions to the `settings.task-preferences`
adapter while it still lived in `pilot-mount-adapters.ts`. This branch had already
moved that adapter into `adapters/task-mount-adapters.ts`, so resolving the
`pilot-mount-adapters.ts` conflict in favour of the registry merge silently
discarded them and `tw-task-preferences-resume-write` failed to record at all
("Missing or completed request: ui.set#1").

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): re-record the RPC goldens at main's tip after the merge

All 208 goldens, header-only. `baseline` moves from 50e752fc66 to main's tip
c6a7216984, `goldenFormatVersion` from 4 to 5, `recorderSha256` to the value of
the engine with `adapters/` and `mutants/` carved out, and `adapterSha256` is new
on every file. Nine distinct adapter digests over 208 goldens: each golden now
pins only the module that mounts it.

No observation moved. The whole-diff census against origin/main reports exactly
four changed keys and nothing else:

  208 "adapterSha256":   416 "baseline":
  416 "goldenFormatVersion":   416 "recorderSha256":

Recorded in place rather than through the README's detached-baseline dance: this
branch changes no product file, so its tree at the merge is byte-identical to
c6a7216984 under mobile/src, src/shared and the lockfile, and the parity claim
stays non-circular. README says so now.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): hold the recording drivers to the engine's mutant-seam rule

The name scan exempted every `.test.ts` on the ground that a test cannot change a
recording. Two of them can: the recording drivers are the recording path. A driver
that read the mutant table by path rather than importing it passed both seam checks
— the import scan sees no import, and the name scan waved it through as a test:

  const table = resolve(import.meta.dirname, 'mutants/operation-mutations.ts')
  console.log(readFileSync(table, 'utf8').length)

at the top of `pilot-recordings.test.ts` gave 2 passed before, and after this change
fails with ["pilot-recordings.test.ts"].

Only non-driver tests are exempt now. This file lives in `mutants/`, which
`recorderSha256` skips, so no golden moves: the recorder suite is green on the
existing 208 with zero dirty.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): drop the registry parameter no caller varies

`pilotMountAdapters` took `registered` so a caller could mount a different module
set; all six callers take the default. The header-digest tests vary the registry
through `goldenRecording`, which keeps its own parameter and is where the stub
roots need it. Engine source, so `recorderSha256` moves and the goldens follow in
the next commit.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): re-record the RPC goldens after the registry parameter came out

All 208, `recorderSha256` only. The re-record against the previous commit moves
416 lines, every one of them that field:

  416 "recorderSha256":

Against origin/main the picture is unchanged from the merge: 208 goldens, 0 added
or deleted, 0 non-header lines, and exactly four keys differing —

  208 "adapterSha256"   416 "baseline"   416 "goldenFormatVersion"   416 "recorderSha256"

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): wrap the recording README at the width the rest of it uses

Seven lines this branch added ran past 100 columns, worst 124. No wording changed.
Markdown is outside `recorderSha256`, so no golden moves.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): name the worktree overlay, not the archive that cannot work

`git archive` was offered alongside a detached checkout as a way to lay this
branch's recorder over the pinned baseline. It cannot work: the fence in
scripts/rpc-recording.mts runs `git diff --quiet <baseline>` and an untracked-file
check, both of which need a real `.git`. In an archive tree git exits non-zero for
lack of a repository and the script reports "Product sources or lockfile differ
from the pinned main baseline", which reads as a product mismatch that is not
there. The transport agent lost time to exactly that.

Names `git worktree add --detach` only, and says what the misleading failure looks
like if someone tries an archive anyway. Markdown is outside `recorderSha256`, so
no golden moves.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): close two ways an adapter module escapes its own digest

Two holes, one class: the seam was checked by how an import was spelled and by
what the register's values evaluated to, never by where they resolve or where they
were written.

Inward imports: the scan dropped every specifier starting with `..`, so
`'../adapters/settings-mount-adapters'` climbed out of the directory and back into
it unseen. A reviewer had `new-tab-agent-mount-adapters.ts` project a value read
from the settings module, edited that module, and watched the mounted state change
while the new-tab adapter digest held. Specifiers now resolve against the
directory and anything landing back inside it fails:

  ["new-tab-agent-mount-adapters.ts imports ../adapters/settings-mount-adapters"]

The register: `adapters/mounted-operation-modules.ts` is pinned by nothing —
`recorderSha256` skips the directory and `adapterSha256` reads each entry's
`source`. An `exposes` written inline there drives the mounted product module with
no digest covering it. The same reviewer replaced the new-tab entry's `exposes`
with a literal overriding `loadMobileNewTabAgentOptions`; twelve fence tests
passed. Both `mounts` and `exposes` must now be identifiers the register imports
from that entry's own module:

  ["new-tab-agent-mount-adapters.ts writes exposes inline instead of importing it"]

Checked on the register's syntax, not its values, because an inline literal and an
imported binding are indistinguishable once evaluated.

Pinning the register in the engine digest would also close it, and is the wrong
trade: every domain adding a register line would re-digest all 208 goldens, which
is the conflict this PR exists to remove. Keeping the register an index costs
nothing and keeps a domain's line local.

Both fixes live in a `.test.ts` outside the drivers, so no golden moves.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): prove the mutant seam from the drivers out, not by spelling

The seam rested on a grep for the literal `mutants`, which the exported
`MUTANT_DIRECTORY` spells without containing. A reviewer had
`pilot-mount-adapters.ts` read the mutant table through that constant and both
checks passed. The README's claim — that nothing on the recording path names the
directory — was false as written.

Three changes, in order of strength:

Reachability is now proved forward. The suite walks the static import graph from
the two recording drivers and fails if any module under `mutants/` is in it. That
answers the real question, what a golden's bytes can depend on, instead of the old
inward scan's question, who mentions this directory. Non-emptiness is asserted on
both sides so a graph that resolved nothing cannot pass by reaching nothing.

The name scan covers both spellings, for paths a module can be read by rather than
imported. The reviewer's probe now fails as ["pilot-mount-adapters.ts"].

`MUTANT_DIRECTORY` is no longer exported. Its two consumers were both tests of the
digest, and they now spell the path instead, which is strictly better for them: a
test that imports the constant follows a rename silently, while one that spells it
fails on a rename — and that specific directory name is the whole soundness
argument. This edits `recorder-digest.ts`, so the goldens re-record in the next
commit.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): re-record the RPC goldens after MUTANT_DIRECTORY stopped being exported

All 208, `recorderSha256` only. Against the previous commit the diff is 416 lines
and every one of them is that field:

  416 "recorderSha256":

Against origin/main, unchanged: 208 goldens, 0 added or deleted, 0 non-header
lines, four keys differing —

  208 "adapterSha256"   416 "baseline"   416 "goldenFormatVersion"   416 "recorderSha256"

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): state the mutant seam's actual argument, and its edge

The README claimed nothing on the recording path names `mutants/`. That was the
old inward scan's claim and a reviewer falsified it with the exported constant. It
now describes what the check does: a forward walk of the import graph from the two
recording drivers, plus a name scan in both spellings for read-by-path, plus the
constant no longer being exported. It also names the case neither closes — a path
assembled from fragments at runtime.

Markdown is outside `recorderSha256`, so no golden moves.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): prove the engine/adapter seam in both directions

The inward scan only held adapters to the seam. An engine file importing an
adapter executes code its own digest skips and that every golden recorded
through another domain leaves out of `adapterSha256`, so the register is now
the only crossing allowed from the engine side.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): name what the driver walk missed instead of counting it

Seeding `seen` with the drivers made the driver-presence check true by
construction, and the size bound compared a graph inflated by `typeof import`
product modules against a recorder-sized number. Both go; the walk now reports
the recording files it failed to reach, which is empty today and names an
orphan engine file the moment one appears.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): reflow four paragraphs left ragged by the rewrap

Orphan fragments only, no wording change: the golden-schema field list, the
mutant-evidence paragraph, the probe-witness sentence and the re-anchor note.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): record the small-domain call sites before migrating them

Thirteen new families cover the files, new-workspace, host-screen, home and
worktree call sites step 4 migrates next: ownership capture, the preview loader
and its terminal-artifact grant refresh, the artifact save, the tab doc's three
shapes, the drawer's execution target and setup hook, the Codex reset-credit
probe, the host view settings, the Home stats card and the three workspace
catalog reads.

Recorded against main's product code, so these are the parity baseline the
refactor must not move. Four new adapter modules under adapters/ and no engine
edit, so recorderSha256 is unmoved and every existing golden is byte-identical:
40 files added, none changed.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): send the small-domain reads through RpcOperation

Thirty-five of the domain's fifty-five raw-port references now go through a
declared operation: the files domain's preview, artifact and tab-doc reads and
its ownership capture, the New Workspace drawer, the host screen's metadata and
view-settings mirror, the Home stats card, and all three workspace catalog reads.

No behaviour change, and the oracle says so: zero goldens move. Acceptance is
preserved call site by call site, including two that look like defects and stay
that way — a refused worktree.listRetiredNames still settles as an empty registry
rather than holding the previous names, and a refused ui.get on a null result
still throws into the host screen's own catch.

Where two call sites disagreed about one method, both policies are named: files.read
and files.readPreview throw for a session file tab and skip for the preview screen,
repo.hooks throws for task create and skips for the drawer, and status.get now
carries a fourth family for the Codex capability probe's object-or-null rule.
The drawer's SSH connect, SSH state and agent detection reuse the workspace-create
operations the tasks migration already declared rather than restating them.

Two things outside the call sites. requestSingleFlight now shares the params
optionality rule that request already had, so an all-optional schema such as
preflight.check can omit its params on both helpers instead of only one; that is
type-level and puts nothing new on the wire. And the retired-names fixture
resolved a reply with no `ok`, a shape no host sends, which read as a refusal once
the acceptance policy routed on it.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): drive the image arm of the preview loader

The mutation census found two migrated operations that no recording reached:
repointing files.readPreview or files.readTerminalArtifactPreview to a wrong
method, and swapping either one's acceptance policy, changed nothing any golden
observed. Both preview-load scenarios read a text path, so the loader's image
branch was migrated with no wire behind it.

Two scenarios now read an image path through each arm, and the adapter takes the
path from the scenario instead of a constant. All four mutations die on the new
goldens. They are recorded from the pinned baseline with this branch's recorder
laid over it, so they are main's behaviour and not the migration's: the candidate
run against the refactored tree compares clean.

The adapter edit re-digests the nineteen goldens mounted through it. The diff is
one adapterSha256 line each and no observation moves, which is what pinning the
adapter per golden rather than per suite is for.

Two casts also take the SAFETY form the house style asks for.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): drop the casts the changed-code gate flags

Seven type assertions the gate counted as new, all removed rather than silenced
where the type system could already answer. `normalizeMobileFilePreviewResponse`
narrows on `ok` instead of asserting each arm; the snapshot adapter narrows on
the fetch result's own discriminant; and the drawer's two probe reads go through
one overloaded member read that keeps their optional-chaining behaviour. The
remaining three keep a cast and now carry the rationale on the asserting line.

No behaviour change. The two adapter edits re-digest the sixteen goldens mounted
through them, one adapterSha256 line each with no observation moved, recorded
from the pinned baseline the same way.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): drop the import the narrowing left behind

RpcSuccess is no longer named once the response reads through its own discriminant.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): record the host screen's worktree mutations

Review of #20705 showed the `use-host-worktree-actions.ts` holdout reason was
wrong: its only native call is the pinned-id write, and that sits behind
`if (hostId)`, so mounting with no hostId never reaches it.

Two scenarios in one new family, recorded from the pinned baseline with the call
site still on the raw port. The first drives all three sends so the reply matrix
covers each method; the second refuses `worktree.rm` to pin the row restore.

The adapter is a new module, so no existing golden's `adapterSha256` moves and
none of the 250 goldens already here is rewritten.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): send the host list's worktree mutations through RpcOperation

Pin, remove and activate move onto operations in host-screen-operations.ts. All
three skip on refusal, which is the policy each site already applied by hand: the
pin and activate writes swallow everything in a `.catch`, and the remove restores
the row on a refused reply. `worktree.set` therefore carries a second policy next
to source-control's `worktree.set-review-link`, which throws; both are named.

Zero goldens move. The inventory loses use-host-worktree-actions.ts and states
the real reason the drawer's repo list stays: it renders the last-visited-repo
hook, whose default import of async-storage the recorder's proxy refuses at
module load, before the hostId guard the reviewer expected to save it.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): type the worktree-action fixture row and follow the activation scan

The fixture row I recorded from had four fields, which `tsc` rejects as a
`Worktree`. Filling it out moves the five goldens of this branch's own new family
and nothing else; the recorded sends are unchanged, only the projected row is.

`mobile-worktree-activation-source.test.ts` scanned the hook for the literal
`sendRequest('worktree.activate'`, which the previous commit replaced. It now
asserts the operation call and its two flags in the hook, plus the method in
host-screen-operations.ts, so the pair still pins the same wire.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): take the five deletions round-1 review asked for

- `fileOwnershipRuntimeStatusRead` was `taskRuntimeStatusRead` field for field.
  It is now a re-export of it. The goldens are keyed on the scenario family, not
  the operation name, so `matrix-files.mutation-ownership-status.get-1.json`
  survives unchanged.
- `readProbeMember`'s two overloads asserted shapes nothing checked. Gone; the
  nested read goes through the same single-signature function.
- `normalizeMobileFilePreviewResponse` had no product caller. Deleted with its
  re-export; its twelve assertions now drive the accepted and refused arms
  directly.
- The three inline copies of the accepted-result union are gone. They name each
  operation's own `interpret` return instead of importing `RpcAcceptedResult`:
  importing the contract would pull all three call sites into the cast fence,
  where their existing SAFETY assertions fail it.
- `codex-reset-credit-capability-operation.ts` is now `-operations.ts`. No
  adapter names it, so no golden re-digests.

Zero goldens move.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): give the skip verdict its own transport module

The three settle helpers typed their interpret parameter as
`ReturnType<typeof <op>.interpret>`, naming one operation while being called with
others whose verdicts happen to be structurally identical. Narrowing a named
reader would have silently retyped unrelated helpers.

`RpcAcceptedResult` moves to `rpc-accepted-result.ts`, outside the cast fence's
three region seeds, so a consumer can name the verdict without becoming an
operation implementation. `rpc-operation-contract.ts` re-exports it.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): drop three sender aliases nothing imports

MobileHostScreenRpcSender, MobileNewWorkspaceRpcSender and
MobileWorktreeCatalogRpcSender each appeared only in the file that declared
them. A named type with no consumer is a cost, not a boundary.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): say why a holdout is a holdout in the port inventory

A site can be pointed at an operation without being mountable, so "cannot be
migrated" was the wrong claim. The rule is record-first: the golden recorded
against the old code is the only parity proof, so a site the recorder cannot
mount cannot be recorded, and unrecorded sites do not migrate. Stated once in
the list's header.

codex-reset-credit.ts loads fine under the module loader; probed it, and its
attempt-journal access throws on async-storage at call time before the send,
with no guard to skip it. The old comment described it as a storage read
around the send.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): state the status.get policies without counting them

"the fourth policy on this method", "the first of two" and "the second of two"
were already wrong after round 1 folded the files family's status read into the
tasks one. Each comment now states its own invariant, which no later policy can
invalidate.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): stop the activation scan claiming to pin the wire

`expect(operations).toContain("method: 'worktree.activate'")` passes whichever
operation carries that method, so it survives swapping worktreePinWrite's and
worktreeActivate's methods. tsc and the host-worktree-actions-pin-open-delete
golden both fail on that swap; the scan keeps only what it can prove, which is
that the callback sends through worktreeActivate with the two flags.
