* feat: leveled response views + --level knob, with a snapshot digest — Phase 4
Add the agent-cost leveled-response system: a responseLevel knob
(digest | default | full) plumbed end to end behind a global --level flag
(mirroring --cost), and a per-command ResponseView registry applied in the
router on the success path.
- contracts: RESPONSE_LEVELS/ResponseLevel + meta.responseLevel + boundary
schema whitelist. Plumbing mirrors --cost: cli-flags FlagDefinition +
GLOBAL_FLAG_KEYS, AgentDeviceClientConfig + overrides, buildClientConfig,
buildMeta. ResponseLevel exported from the public root.
- src/daemon/response-views.ts: the ResponseView registry. Seeds the snapshot
digest — the full node tree (the dominant token sink) collapses to
{ nodeCount, refs: first 12 hittable/non-occluded refs with labels } plus the
cheap top-level signals (truncated/visibility/snapshotQuality). full returns
today's shape (nothing richer is computed yet).
- router graft (applyResponseLevelView + applyAgentCostGrafts): composes with
the existing cost block. With responseLevel default (or unset) AND no
registered view AND no --cost, the original response is returned UNCHANGED —
byte-identical to today (Maestro .ad recompare safe). cost.nodeCount reads the
original node tree so it stays accurate even after a digest.
Tests: snapshot view unit test (digest filters hittable/occluded, drops the
tree, keeps cheap signals; default/full passthrough); router graft test via an
injected view (default identity byte-identical, digest applies, full passthrough,
digest+cost composition, unregistered-command passthrough, boundary parse).
Verified: tsc, oxfmt + oxlint --deny-warnings, fallow audit clean, rslib build,
Layering Guard empty, 1106 daemon/contracts/client tests pass (incl. the
existing cost/typed-error grafts after the restructure).
* fix: repoint MCP output-schemas import to kernel/device (rebase fixup)
The kernel move (#940) deleted src/utils/device.ts; #941's
command-output-schemas.ts (merged after #940's codemod ran) still imported the
old path. Same one-line fix as #943; de-dups once that lands.
* fix: re-classify responseLevel flag in integration-progress model
The --level/responseLevel flag is a diagnostics/output flag (not device-
observable), classified in the exclusion bucket alongside --cost. (Lost in an
earlier rebase; re-applying.)
#941 (MCP outputSchema) and #940 (errors/redaction/device -> src/kernel) merged
in an order where #940's import codemod never saw #941's new
command-output-schemas.ts, so it still imports '../utils/device.ts' — which no
longer exists. tsc/build on main is red. Repoint the import at
'../kernel/device.ts'. The only stale reference on main.
* refactor: move errors/redaction/device into src/kernel — Phase 5 slice 3
Relocates the foundational primitive trio from src/utils/ into the kernel/ layer
(joining snapshot.ts from slice 2), per the target folder DAG in
plans/perfect-shape.md §5.5. A pure path codemod, no behavior change.
They form a closed cluster — device -> errors -> redaction, with redaction a
leaf — so kernel/ takes no upward dependency, and every importer becomes a clean
downward import toward kernel. errors.ts is the most-imported module in the
tree; device.ts the §5.5-named headliner. Moving all three atomically avoids a
half-state where one would import another across the utils/kernel boundary.
Imports rewritten by a resolve-based codemod (compares each specifier's resolved
path to the moved files, so the unrelated commands/management/device.ts and
other same-named files are untouched): 483 sites across 402 files. The two
platform-descriptor doc comments and the fallow health baseline key for
device.ts are updated to the new path; the contracts-schema-public guard that
asserts the error helpers pull no diagnostics/node: deps now reads kernel/.
Verified: tsc --noEmit, oxfmt + oxlint --deny-warnings, rslib build, full vitest
suite (2877 pass), fallow audit clean (411 changed files), Layering Guard empty;
kernel/ files import only within kernel.
* docs: update guidance references to kernel/{device,errors} after the move
AGENTS.md (Apple-family sync rule + normalizeError), ADR-0009, and
plans/apple-platform-consolidation.md still named the old src/utils/ paths.
Point them at src/kernel/. plans/perfect-shape.md's utils/device.ts mention is
left as-is — it describes the pre-move diagnosis.
* feat: per-command MCP outputSchema — Phase 4
Hand-author per-command MCP outputSchemas for the 13 typed commands whose
closed result shapes live in the contracts layer (mirroring CommandResultMap):
press, fill, longpress, boot, shutdown, viewport, home, back, rotate,
app-switcher, clipboard, appstate, keyboard.
The new COMMAND_OUTPUT_SCHEMAS registry is injected into tools/list via
listCommandTools(). It is additive-only: untyped/dynamic tools (snapshot,
gestures, perf, logs, …) carry no outputSchema key and stay byte-identical.
Schemas are non-strict (no additionalProperties:false) so the additive cost
object rides into structuredContent and still validates. MCP agents can now
trust structuredContent against the advertised schema instead of re-parsing
text.
* refactor: type-tie COMMAND_OUTPUT_SCHEMAS to CommandResultMap
Replace Partial<Record<string, JsonSchema>> with
`satisfies Record<keyof CommandResultMap, JsonSchema>`, so the one-for-one
invariant with the typed-result spine is compiler-enforced: a new
CommandResultMap entry without an output schema is now a missing-key error, and
a misspelled/extra key is an excess-property error (previously both compiled and
silently omitted the schema). The lookup in listCommandTools guards with an `in`
check since the registry is keyed by the typed commands only.
Graft the Phase 2 TypedError signals onto DaemonError: machine-readable hints an
agent can act on without a wasted round-trip.
- supportedOn: for UNSUPPORTED_OPERATION / UNSUPPORTED_PLATFORM errors, the
platform families that DO support the command, DERIVED from the capability
matrix (new supportedPlatformsForCommand in core/capabilities.ts). So an agent
that hit a platform mismatch learns where the command works.
- retriable: flags transient failures worth retrying. Conservative policy
(retriableForErrorCode in utils/errors.ts) — currently only DEVICE_IN_USE
(device healthy but busy); ambiguous/deterministic codes stay undefined.
Both are additive and applied at a single chokepoint (handleRequest, where the
command is in scope) only when a signal applies, so the default error wire shape
is unchanged for the common codes — verified across 1632 daemon/core/contracts/
utils/commands tests (no error-shape ripple). New unit + router e2e test covers
all three cases (supportedOn present, retriable true, deterministic unchanged).
Verified: tsc --noEmit, oxfmt + oxlint --deny-warnings, fallow audit clean,
Layering Guard empty.
Wire `keyboard` into the CommandResultMap spine, grounded in the dispatch
handlers' literal returns (src/core/dispatch.ts handleAndroidKeyboardCommand /
handleIosKeyboardCommand).
Modeled as a flat closed shape (platform + action always present; the remaining
keyboard-state / message fields appear per branch) rather than a five-way
platform×action union — the per-branch field sets overlap heavily and the
underlying Android keyboard-state types live in the platform layer (below the
public contract). The Record index signature of the previous hand-written mirror
is dropped and the spurious `| null`s removed (the handler never returns null).
Moves from the open client-types.ts mirror into src/contracts/keyboard.ts, wired
through CommandResult<'keyboard'>; public export name preserved (re-exported via
client-types.ts -> index.ts), so no API break. Parity test pins all 13 migrated
commands.
Stacked on the batch 3 PR. Verified: tsc --noEmit, oxfmt + oxlint
--deny-warnings, fallow audit clean, Layering Guard empty, 379 tests across
core/contracts/client/commands/system pass.
Wire two more commands into the CommandResultMap spine as closed shapes,
grounded in the handlers' literal returns:
- clipboard (src/core/dispatch.ts handleClipboardCommand) -> a discriminated
union on `action`: read => { text }, write => { textLength, message }.
- appstate (src/daemon/handlers/session-state.ts handleAppStateCommand) -> a
discriminated union on `platform`: Apple (ios/macos) session state — now
including the iOS-only device_udid / ios_simulator_device_set locators the
previous hand-written mirror OMITTED — or Android package/activity.
Both result types move from the open client-types.ts mirror (DaemonResponseData
& {…}) into new src/contracts/{clipboard,app-state}.ts and are wired through
CommandResult<'clipboard'> / CommandResult<'appstate'>. Public export names are
preserved (re-exported via client-types.ts -> index.ts), so no API break.
Tightening clipboard to a closed union surfaced an unguarded .text/.textLength
access in an Android integration test (previously masked by the Record index
signature); fixed with discriminant guards. The parity test now pins all 12
migrated commands; the public-root export test gains clipboard/appstate samples.
Verified: tsc --noEmit, oxfmt + oxlint --deny-warnings, fallow audit clean,
Layering Guard empty, 791 tests across core/contracts/client/commands pass.
Wire four more commands into the CommandResultMap spine, narrowing their public
client return types from the open DaemonResponseData bag to closed shapes.
Each shape is grounded in a re-read of the dispatch handler's literal return
(src/core/dispatch.ts DISPATCH_HANDLERS) — a fixed `action` discriminant plus
the always-present successText `message`:
- home -> { action: 'home'; message }
- back -> { action: 'back'; mode: BackMode; message }
- rotate -> { action: 'rotate'; orientation: DeviceRotation; message }
- app-switcher -> { action: 'app-switcher'; message }
The handlers spread nothing else, so the shapes are closed (consistent with the
viewport contract, the generic-dispatch Android dialog-recovery `warning`
annotation is intentionally not part of the contract). The result types move
from the client-types.ts mirror into a new src/contracts/navigation.ts; the
now-unused CommandActionResult helper is deleted. Public export names are
preserved (re-exported via client-types.ts -> index.ts), so no API break.
The exact-equality parity test pins CommandResult<name> === the contract type
for all ten migrated commands; the public-root export test gains back/rotate
samples.
Verified: tsc --noEmit, oxfmt + oxlint --deny-warnings, fallow audit clean,
Layering Guard empty, 791 tests across core/contracts/client/commands pass
(the lone failure was the known-flaky daemon-client mid-stream-abort test, which
passes in isolation).
Establishes the kernel/ layer from the perfect-shape DAG (plans/perfect-shape.md
§5.5) by moving the foundational snapshot type module (Rect, SnapshotNode,
SnapshotQualityVerdict, centerOfRect — re-exported by contracts.ts and imported
by ~130 files) from src/utils/snapshot.ts to src/kernel/snapshot.ts.
Pure path codemod, no behavior change. snapshot.ts is a leaf (zero imports, after
the preceding cycle-break PR), so kernel/ takes no upward dependency — and every
one of its ~130 importers (utils, core, daemon, platforms, commands, tests)
becomes a clean downward import toward kernel. This also unblocks the future
snapshot/ AX-domain extraction: those domain files now import DOWN into kernel
rather than sideways within utils.
Imports rewritten by a resolve-based codemod (compares each specifier's resolved
path to the old module, so the other snapshot.ts files under commands/platforms/
daemon are untouched). 138 sites across 128 src files + 2 integration worlds.
Verified: tsc --noEmit, oxfmt + oxlint --deny-warnings, full vitest suite
(308 files / 2863 tests), fallow audit clean (133 files), rslib build, Layering
Guard empty; kernel/snapshot.ts confirmed import-free.
snapshot.ts (the foundational snapshot type module; Rect/SnapshotNode, 96
importers, re-exported by contracts.ts) imported SnapshotQualityVerdict from
snapshot-quality.ts, which in turn imports SnapshotNode from snapshot.ts — a
type-level cycle that blocks moving snapshot.ts down into a kernel layer.
Move the SnapshotQualityVerdict type definition into snapshot.ts (it is
referenced by a SnapshotNode field) and re-export it from snapshot-quality.ts so
every existing `from './snapshot-quality.ts'` import is unaffected. The
validation logic (readSnapshotQualityVerdict + const Sets) stays put.
Result: snapshot.ts has zero imports (a clean leaf), unblocking the kernel-seed
move and the eventual snapshot/ domain extraction. No behavior change.
Verified: tsc, oxfmt + oxlint --deny-warnings, fallow audit clean, 369 tests
across utils pass.
First Phase 5 (layering) move: a pure path codemod, no behavior change. Relocates
the cohesive screenshot-diff domain (9 source files + 3 tests) from src/utils/
into a dedicated top-level src/screenshot-diff/ folder, per the target folder DAG
in plans/perfect-shape.md §5.5.
Boundary respects the real dependency graph:
- screenshot-diff-pixels.ts STAYS in utils — it is the pixel-diff primitive the
shared png-worker depends on, not domain code. No moved file imports it.
- the moved files keep importing shared utils (png, exec, screenshot-geometry,
snapshot, errors) via ../utils/.
- consumers updated: commands/capture/runtime/diff-screenshot.ts and
utils/output.ts (the diff result-type formatter).
fallow-baselines/health.json keys for the two flagged files are renamed to the
new paths to preserve the baseline (no new findings).
Verified: tsc --noEmit, oxfmt + oxlint --deny-warnings, fallow audit (clean, 16
files), rslib build, and 431 tests across screenshot-diff/utils/capture all pass;
Layering Guard empty. git tracks all 12 as renames.
Note: utils/output.ts now imports the screenshot-diff result types cross-folder
(it formats diff output); when the import-direction lint lands it should move up
out of utils. Tracked as a Phase 5 follow-up.

* refactor: dedupe Apple runner option plumbing
Extends the opt-in cost block (slice 1 wallClockMs, slice 2/#925
runnerRoundTrips) with a command-agnostic nodeCount: the size of the UI/
accessibility node tree a command returns. In production only the snapshot
node-tree commands put a `nodes` array on response.data, so the router reads
it generically (Array.isArray(response.data.nodes)) and omits nodeCount
everywhere else. It lets an agent size a snapshot before re-fetching at a
different depth/scope, without parsing the full tree.
Purely additive and gated on meta.includeCost + response.ok, exactly like the
existing cost fields: with the flag off the serialized response is byte-
identical to today (Maestro .ad recompare safe). nodeCount is a pure read of
the existing nodes array — the parity test proves deleting the cost block
leaves a payload deep-equal to the flag-off response. Additive / semver-minor.
Slice 1 added the opt-in cost.wallClockMs field on the daemon response; it
already rides on response.data → MCP structuredContent. This slice adds the
MCP-boundary opt-in so agents can request it: an includeCost tool argument
(mirroring the existing stateDir / mcpOutputFormat MCP config fields) that maps
to the client `cost` config (→ meta.includeCost on the daemon).
- readClientConfig sets client.cost = true only when includeCost === true, and
rejects non-boolean values at the boundary.
- includeCost is stripped from the command input so it never leaks as a flag.
- withMcpConfigSchema advertises includeCost: boolean in each tool inputSchema.
Default-off is unchanged: with includeCost absent or false, the client config
and the MCP structuredContent are byte-identical to today. Additive /
semver-minor. Per-command MCP outputSchema and richer signals stay deferred.
* feat: opt-in agent-cost wallClockMs behind --cost
Add per-command wall-clock latency as a purely additive, opt-in response
field (cost.wallClockMs) gated behind a new global --cost flag.
The flag plumbs end to end mirroring --debug: cli-flags definition +
GLOBAL_FLAG_KEYS, AgentDeviceClientConfig/overrides, buildClientConfig,
buildMeta (meta.includeCost), the DaemonRequestMeta contract, and the
boundary parse in daemonCommandRequestSchema so it survives the HTTP edge.
The graft lives in request-router handleRequest (the seam that owns the
outer wall-clock incl. lock + execute + finalize). It mirrors the
conditional registerDownloadableArtifacts spread: when --cost is off OR the
response is an error, the response is returned untouched. Only on an opted-in
successful response is cost appended, so the default serialized DaemonResponse
is byte-identical to today (Maestro .ad recompare safe). Proven by the parity
test (flag-off identity, flag-on additive-only, error path, boundary survival).
Additive / semver-minor. MCP exposure and richer signals (roundTrips,
nodeCount) are deferred to follow-up slices.
* test: classify --cost flag as outside provider-backed integration
The integration progress guard (test:integration:progress:check) treats every
public CLI flag as either device-observable (requiring provider-backed coverage)
or intentionally excluded. --cost is a diagnostics/output flag (a purely additive
response field, not device-observable), so it joins json/help/version/verbose in
the 'config, output, diagnostics, and transport' exclusion bucket.
Replace scattered inline `platform === 'ios' || === 'macos'` and `=== 'ios' || === 'android'` family-grouping branches with the shared `isApplePlatform`/`isMobilePlatform` leaf predicates. Strictly behaviorless: each site yields an identical boolean for every possible platform input. Adds `isMobilePlatform` to utils/device.ts (leaf predicate, no registry/core import). Part of the Phase 3 PlatformPlugin/ADR-0009 effort to reduce open-coded platform branches; defers the ios+macos→apple Platform collapse and load-bearing table relocations per ADR-0009.
* feat: typed command results, batch 1 (boot, shutdown, viewport)
Wire the dormant CommandResultMap spine into the public client return types
for three commands whose daemon handlers return clean, closed result objects:
- boot -> BootCommandResult (src/daemon/handlers/session-state.ts)
- shutdown -> ShutdownCommandResult (src/daemon/handlers/session-state.ts)
- viewport -> ViewportCommandResult (src/core/dispatch.ts handleViewportCommand)
Each result type mirrors the handler's literal return exactly; the public
client methods narrow from the generic Record (CommandRequestResult) to these
precise shapes. No field removed; shapes that the runtime leaves open stay open.
* fix: export typed command results
* feat: derive capability bucket from a PlatformDescriptor registry
Introduce src/core/platform-descriptor/ (mirroring src/core/command-descriptor/):
a 5-row PlatformDescriptor registry carrying each leaf platform's capability
bucket and isApple flag, pure derive folds, and a byte-for-byte parity test.
Rewrite selectCapabilityForPlatform to fold the registry via the derive fn and
delete the hand switch. Behaviorless and parity-proven; layering-safe (all in
core, no utils->core inversion). Defers the ios/macos->apple collapse and the
interactor/discovery/runner-profile tables to later per ADR-0009.
* refactor: drop unused definePlatformDescriptor helper
The identity helper had no consumers (the registry uses `as const satisfies`),
so Fallow flagged it as a newly-added unused export. Remove it.
The command-descriptor registry is now `as const` (#910), so each entry keeps
its literal `name` and literal `batchable`. Derive StructuredBatchCommandName
from it via `Extract<…, { batchable: true }>['name']` instead of the 43-member
hand-authored union from #909, and delete the now-tautological exhaustive Record
membership assertion in parity.test.ts (type and value now derive from the same
`batchable: true` entries).
Strictly behaviorless: the derived union is the identical 43-member set
(confirmed bidirectionally assignable to the old hand union, member count
unchanged), the runtime allowlist value is unchanged, and the public
BatchCommandName re-export is structurally identical (consumer switches on
specific batch command names still typecheck).
* feat: registry-driven exhaustive command dispatch — Phase 1 step 5
Part A (enabler): make commandDescriptors `as const` so each entry keeps its
literal `name`, and export `Command` — the literal command-name union.
Part B: replace the dispatchKnownCommand switch with a
`Record<DispatchCommand, DispatchHandler>` lookup table. The Record type forces
every dispatch command to have a handler (a missing entry is now a COMPILE
error, replacing the runtime `default: throw` as the coverage net); an
`Object.hasOwn` guard preserves the identical INVALID_ARGS error for unknown
commands. DispatchCommand is hand-authored to match the switch cases verbatim
(it is not the registry `generic` route, and `swipe-preset`/`read` aren't
registry names). Strictly behaviorless: same routing, same handler args, same
results.
* feat: additive CommandResult type spine — Phase 1 step 6
Part A (enabler): make commandDescriptors `as const` so each entry keeps its
literal `name`, and export `Command` — the literal command-name union.
Part B: replace the dispatchKnownCommand switch with a
`Record<DispatchCommand, DispatchHandler>` lookup table. The Record type forces
every dispatch command to have a handler (a missing entry is now a COMPILE
error, replacing the runtime `default: throw` as the coverage net); an
`Object.hasOwn` guard preserves the identical INVALID_ARGS error for unknown
commands. DispatchCommand is hand-authored to match the switch cases verbatim
(it is not the registry `generic` route, and `swipe-preset`/`read` aren't
registry names). Strictly behaviorless: same routing, same handler args, same
results.
Build BASE_COMMAND_CAPABILITY_MATRIX from deriveCapabilityMatrix(commandDescriptors)
and delete the hand-authored literal (ADR-0008, Phase 1 step 3). Behaviorless: #906
proved the derived matrix is byte-equal to the literal, including the
supports/unsupportedHint closures across the sample-device matrix.
Delete the now-dead local predicate helpers and capability bundles that only the
literal referenced (isNotMacOs, isMacOsOrAppleSimulator, isIosMobileSimulator,
synthesisGestureUnsupportedHint, ALL_DEVICE_COMMAND_CAPABILITY, APP_* bundles,
LINUX_DEVICE, LINUX_NONE); their copies now live in registry.ts. WEB_* command
sets and addWebCommandCapabilities are kept.
The registry/derive/types modules only type-import CommandCapability from
capabilities.ts, so the new value-level dependency forms no runtime cycle (tsc
clean + runtime import() of capabilities.ts loads with no TDZ/circular-init error).
Rewrite the capability parity tests (now tautologies) into an admission invariant:
every matrix entry is selectable (platform bucket or supports predicate) and the
public-command coverage floor is unchanged. Daemon and batch-name parity tests kept.
Introduce a single dormant CommandDescriptor registry as the strangler-fig
spine for ADR-0008. Per command it carries the daemon route + request-policy
traits (incl. closure traits), an optional capability entry, and
batchable/mcpExposed flags — copied verbatim from today's hand tables.
Pure derive folds reconstruct DAEMON_COMMAND_DESCRIPTORS, the capability
matrix, and the structured-batch names; parity tests prove each derivation
byte-equal to the live hand table. Nothing reads the registry yet.
Purely additive: no consumers changed, nothing deleted, no import inversion.
The only edits outside the new directory expose three existing tables
(DAEMON_COMMAND_DESCRIPTORS, DaemonCommandDescriptor, BASE_COMMAND_CAPABILITY_MATRIX)
so the parity tests can read them.
Locks the two axis decisions and starts retiring plans/ into ADRs. ADR 0008
(Proposed) records the command-descriptor registry composing domain-owned facets
and deriving the ~10 tables, bound by ADR 0003's four invariants; ADR 0009
(Accepted, groundwork shipped in #896) records the AppleOS leaf axis under one
'apple' Platform. perfect-shape.md links both and marks Phase 0 + Tier-A dedup as
merged.
Collapse three repeated daemon-handler patterns into shared helpers in
src/daemon/handlers/response.ts and handler-utils.ts:
- requireCommandSupported(command, device, { message?, hint? }) replaces ~21
verbatim isCommandSupportedOnDevice UNSUPPORTED_OPERATION guards. The richest
variant (generic dispatch) folds the unsupportedHintForDevice hint behind the
`hint` option; custom-message sites pass `message`.
- noActiveSessionError() / NO_ACTIVE_SESSION_MESSAGE replace the duplicated
'No active session. Run open first.' SESSION_NOT_FOUND literal across handlers
(and the inline router/AppError variants).
- recordSessionAction gains optional positionals/flags overrides so ~15 inline
sessionStore.recordAction({ command, positionals, flags, result }) literals
(find, record-trace, record-trace-recording, session, session-close,
session-perf-xctrace, install-source) route through the one wrapper.
behaviorless: every site keeps its exact error code/message (and hint where
present) and recorded action shape; helpers reproduce each variant.
Both the snapshot helper and the multi-touch helper drive 'am instrument -w'
and parse the same INSTRUMENTATION_STATUS/INSTRUMENTATION_RESULT key/value
records, and both validate a bundled JSON manifest with the same integer and
literal field rules.
Extract the genuinely-identical parts into a shared
src/platforms/android/instrumentation-helper.ts:
- parseInstrumentationRecords (status + result record parsing) and the
shared key/value reader
- readInstrumentationResultNumber / readInstrumentationResultBoolean
- readAndroidHelperManifestInteger / readAndroidHelperManifestLiteral
(label-parameterized so each helper's exact error message is preserved)
multitouch-helper now consumes the shared record parser (was its own
~25-line copy) and the shared numeric reader; snapshot-helper-capture
re-exports the shared metadata readers under their existing public names so
snapshot-helper-session keeps importing them unchanged.
Behaviorless: the divergent, behavior-bearing parts are intentionally left
in each consumer (install caches Set vs Map + install-policy/forget/retry,
installed-versionCode regex + timeout, sha256File stream-vs-read,
readString trim semantics and the sha256 validator that depends on it,
artifact resolution + per-helper manifest schemas).
* refactor: validate JSON-RPC at the MCP/HTTP boundary
Wire the previously dead jsonRpcRequestSchema into the MCP stdio decode path and
add a sibling commandRpcParamsSchema for the daemon HTTP command params, replacing
unchecked casts of attacker-controllable wire input with real boundary parsing.
- mcp/server.ts: each inbound payload (and each batch element) is parsed via
jsonRpcRequestSchema instead of being force-cast to JsonRpcMessage. Valid
requests (with id), notifications (no id), and batches are accepted and routed
exactly as before; only genuinely malformed input (non-object, or wrong-typed
jsonrpc/method/id) is rejected with the standard -32600 Invalid Request error.
JSON.parse failures still surface as -32700, and malformed input never crashes.
- contracts.ts: add commandRpcParamsSchema next to jsonRpcRequestSchema validating
the command RPC params; optionalStringArray helper added.
- daemon/http-server.ts: replace the 'params as unknown as Partial<DaemonRequest>'
double-cast with commandRpcParamsSchema.parse(params).
* fix(daemon): reject malformed command params as 400/-32602
methodToDaemonRequest validated command params via commandRpcParamsSchema.parse, which throws a plain Error on malformed input. That mapped to UNKNOWN -> HTTP 500 / -32000 and leaked the internal '$.x' schema path on the wire. Reporting malformed client input as a server error is the wrong signal.
Wrap the parse so failures throw AppError('INVALID_ARGS', 'Invalid params: ...') with the schema path sigil stripped, and map normalized INVALID_ARGS to JSON-RPC -32602 in the boundary catch so malformed command params now surface as 400/-32602, matching the explicit sibling checks.
* feat: add AppleOS discriminant to the device model (additive)
Add an explicit, stored AppleOS ('ios' | 'ipados' | 'tvos' | 'watchos' |
'visionos' | 'macos') and an optional appleOs field on DeviceInfo so Apple
operating systems are first-class instead of inferred late from DeviceTarget.
- device.ts: add AppleOS type, optional DeviceInfo.appleOs, and make
resolveApplePlatformName prefer device.appleOs while falling back to the
existing target-based inference for legacy records. iOS and iPadOS both map
to the single iOS runner profile; tvOS -> tvOS; macOS -> macOS.
- Populate appleOs at discovery only (no widened filters): iPhone/iPod -> ios,
iPad -> ipados, tvOS -> tvos, host Mac -> macos.
- resolveRunnerPlatformName threads device.appleOs through.
Non-breaking groundwork for the platforms/apple consolidation: records without
appleOs resolve byte-identically, and no runner SDK/destination selection
changes (iPad still resolves to the iOS runner profile).
* fix: keep appleOs internal and derive ipados from simctl device type
The set of platforms was hand-restated in three places that must agree:
the canonical tuples in src/utils/device.ts, the --platform flag's
enumValues in cli-flags.ts, and the leaf-platform validation in
client-normalizers.ts. The two non-canonical copies could drift.
- Export PLATFORMS from device.ts and add an isPlatform() leaf-platform
type guard derived from it (excludes the `apple` selector).
- Derive the --platform enumValues and usageLabel from PLATFORM_SELECTORS.
- Derive normalizeOpenDevice's leaf-platform check from isPlatform();
per-platform udid/serial identifier shaping is unchanged.
Behaviorless: the derived sets equal the previous hardcoded sets.
* docs: add perfect-shape architecture roadmap
Captures the target architecture (two-registry thesis: CommandDescriptor +
PlatformPlugin over a clean folder DAG with a typed-result spine) and a sequenced,
strangler-fig migration path, grounded in a survey of the current codebase.
This PR implements the first two behaviorless Phase-0 items from that roadmap; the
larger registry work is deliberately deferred to later, independently shippable PRs.
* refactor: parametrize RecordingBackend by recording tag
RecordingBackend is now generic over the recording's platform tag, so each
backend's stop() receives an already-narrowed recording. This deletes all five
'recording as Extract<ActiveRecording, { platform: ... }>' casts — the textbook
discriminated-union-narrowing-by-cast anti-pattern — and makes a backend/tag
mismatch unrepresentable.
start() stays wide (DaemonResponse | ActiveRecording) because a device platform
does not map 1:1 to a recording tag (an iOS device resolves to either the 'ios' or
'ios-device-runner' recording). Device resolution returns a stop-less view
(RecordingStartBackend); stop is dispatched per active recording via the new
exhaustive stopActiveRecording(), replacing resolveRecordingBackendForRecording().
Behaviorless: pure type-level change, no runtime behavior change.
* refactor: make capability platform selection exhaustive
isCommandSupportedOnDevice resolved the per-platform capability bucket with an
if/else ladder whose final branch funneled every unmatched platform into
capability.web. That silently absorbs a future Platform with no compile error.
Replace it with selectCapabilityForPlatform(), an exhaustive switch over the
Platform union with a 'never' guard, so adding a new platform is a compile error
here instead of a silent web mis-gate. Identical behavior for all five current
platforms (ios/macos -> apple, android, linux, web).
* docs(adr): amend ADR 0003 for the single-declaration/derivation model
Ratifies the PR review caveat into the ADR itself: the daemon command registry
boundary is about ownership + the predicate interface, not the physical file a trait
is typed in. A derived/projected daemon registry is permitted only if it preserves
four invariants (daemon-owned declaration, unchanged predicate interface, no leakage
into public projections, one declaration per concern enforced by types). The original
decision stands; collapsing daemon policy into a public command registry remains
forbidden.
* docs: refine command axis to facet composition (ADR 0003-aligned)
- §2/§5.2: CommandDescriptor composes domain-owned facets (surface@commands,
capability@core, daemon@src/daemon) and projects them — compose-with, not
collapse-into. Adds the four ADR-0003 invariants.
- §6: mark the two shipped Phase-0 items (generic RecordingBackend<P>, exhaustive
capability selection); link the Apple plan from Phase 3.
- §5.1: Apple as the first PlatformPlugin instance, owning an AppleOS leaf axis.
- §8: before/after diagrams for the command axis + the two-axis summary.
* docs: add apple-platform-consolidation plan (AppleOS leaf axis)
One 'apple' Platform with an AppleOS discriminant (ios/ipados/tvos/watchos/
visionos/macos) rather than six Platform literals (which would collide with the
cross-platform 'target' axis). Captures the 4-investigator survey: ~85% of
platforms/ios is already the OS-agnostic Apple engine; the XCTest runner already
builds ios|macos|tvos; macOS is included as a distinct AppKit leaf (already
entangled). visionOS is scoped net-new work; watchOS is an unsupported sentinel
(XCUITest can't drive it). Before/after diagrams, per-OS readiness, sequencing.
* feat: add integrated device leasing
* fix: keep metro bearer token out of generated proxy profile
The proxy connect profile is written to disk as a non-secret remote config,
but it unconditionally copied `metroBearerToken` into that file, leaking the
secret at rest. Mirror the cloud path, which keeps `daemonAuthToken` in-memory
only: the token still flows through this connect via the returned flags, and
later commands re-supply it via AGENT_DEVICE_METRO_BEARER_TOKEN. Extend the
non-secret-profile test to assert the bearer token is absent from disk.

* fix: always release device lease on session close
releaseSessionLease + sessionStore.delete ran only on the happy path, after
several awaits (app-log/perf/snapshot teardown, platform close dispatch,
runner stop) that can throw. A failed close therefore stranded the device
lease until the inactivity expiry. Wrap teardown in try/finally so ownership
is always freed; the original error still propagates after finally.
