refactor(mobile): break module cycles with focused extractions - #13151

Conversation
The mobile audit found real circular imports: composer attachment preview retention lived in `state/use-composer-drafts` while `lib/attachmentUpload` and `lib/localAttachmentPreview` called it and composer-draft cleanup reached back into `lib/attachmentUpload`, closing a cycle through the attachment/session state cluster; and four component pairs shared a prop/request type in one direction while importing the component in the other (`FilePreview` ↔ `FilePreviewModal` ↔ `MediaImagePreview`, `ConfirmDialogHost` ↔ `MaterialConfirmDialog`, `SegmentedControl` ↔ `MaterialSegmentedControl`, `reviewWordDiffs` ↔ `shikiReviewHighlighter`). Each cycle gets the smallest honest seam: - `lib/composerAttachmentPreviewRetention.ts` now owns the preview-retention lease; composer draft state registers the owner-side cleanup hook at load, so lib no longer imports `state/use-composer-drafts` and the cycle is gone in both directions. Behavior (retain during preview/upload, retry the unused-file sweep on last release) is unchanged. - Shared component shapes move to `.types.ts` modules (`ConfirmDialog.types.ts`, `SegmentedControl.types.ts`, `FilePreviewModal.types.ts`, `reviewHighlightedToken.types.ts`); the old homes re-export them so external call sites are untouched. - `legacy-plan-mode.ts` was pure contract-shaped model logic imported by state from `features/threads`; it moves to `state/`. - `src/dependency-graph.test.ts` is the regression check: no circular static imports (dynamic `import()` stays the documented async escape hatch), plus shrink-only ceilings on the remaining upward edges (state→features 6, lib→features 7, components→features 33, native→features 8, lib→state 11). `lib/runtime.ts` edges count toward the ceiling since it is the composition root. No HomeScreen, thread-list, or package.json changes. Done by callstack/Apex in pi.

ApprovabilityVerdict: Approved at Macroscope's review found this PR approvable — This is a focused mobile dependency-cycle refactor with type-only extractions, a mechanical model relocation, and a small attachment-retention seam that preserves existing lease and cleanup behavior. The substantial added dependency-graph code is test-only, and no product defaults, user-facing capability, sensitive package, or static-analysis suppression is changed. Notes:

Review of #13151 found the dependency-graph guard resolved `./X` to the generic `.tsx` before the `.android.tsx` variant, hiding a real Android cycle: `ThemedSwitch` imports `MaterialSwitch` (which resolves to the `.android.tsx` variant on Android) while that variant type-imports `ThemedSwitchProps` back from `ThemedSwitch`. - Extract `ThemedSwitchProps` to `components/MaterialSwitch.types.ts`; `ThemedSwitch` re-exports it, the Android variant imports from the types module. Acyclic under any resolution order. - The guard now models Metro's per-platform resolution (platform ext before `.native` before generic, and each platform's graph excludes the other platform's variant files) and asserts zero circular static imports under both iOS and Android resolution. Verified against the seeded Android-only cycle the review described. - Ceiling counts now dedupe unique `from -> to` module pairs across both platforms (same numbers as before: 6/7/33/8/11).

Enforce the dependency-edge ratchets.
The header requires each configured value to decrease when a counted upward edge is removed. toBeLessThanOrEqual(ceiling) permits a lower count, so it does not enforce that requirement. Use exact equality.

Upstream's module-cycle pass (pingdotgg#13151) lowered the `state -> features` import ceiling to 6, and the fork sat at 7. `threadAllowsProviderSwitch` is pure model logic over a thread shell and projection with no feature dependencies, so it belongs beside the composer state that reads it — the same move upstream made for `legacy-plan-mode`.

The problem
Mobile audit item #13: the app has real circular imports. Composer attachment preview retention lived in
state/use-composer-draftswhilelib/attachmentUpload/lib/localAttachmentPreviewcalled it, and composer-draft cleanup reached back intolib/attachmentUploadthrough anawait import()escape hatch — a bidirectional state↔lib dependency that only avoided a static cycle via dynamic-import gymnastics (madge counts the dynamic edge and reports it as cycles 1–4). On top of that, four component pairs shared a prop/request type in one direction while importing the component in the other, and a fifth cycle (ThemedSwitch↔MaterialSwitch) hides behind Android platform resolution:FilePreviewModal↔FilePreview↔MediaImagePreviewConfirmDialogHost↔MaterialConfirmDialogSegmentedControl↔MaterialSegmentedControlreviewWordDiffs↔shikiReviewHighlighterThe audit's other entries (
state/thread-order→ thread-list model,lib/runtime→ cloud/observability,components/native→ appearance, etc.) are one-directional upward edges, not cycles — this PR pins them instead of untangling them.The fix
Smallest honest seam per cycle:
lib/composerAttachmentPreviewRetention.tsnow owns the preview-retention lease. Composer draft state registers the owner-side cleanup hook at module load, removing thelib → state/use-composer-draftsupward edges that forced the dynamic-import round trip. Behavior is unchanged: the file stays readable until the last preview/upload release, which still retries the unused-file sweep. The registered hook mirrors the existingConfirmDialogHostmodule-level registration idiom; while unregistered a release simply skips the retry, which is exactly the pre-existing state (no draft store loaded ⇒ no owners to sweep). A callback-parameter API instead would have re-introduced thelib → stateedge at every call site..types.tsextractions (following the existingControlPillMenu.types.tsprecedent):ConfirmDialog.types.ts,SegmentedControl.types.ts,FilePreviewModal.types.ts,reviewHighlightedToken.types.ts. The old modules re-export the types so external call sites (includingfeatures/threadsandfeatures/files) are untouched.legacy-plan-mode.ts→state/: it is pure contract-shaped model logic thatstate/thread-outbox-modelandstate/use-thread-composer-stateimported out offeatures/threads.ThemedSwitchProps→MaterialSwitch.types.tsfor the Android-hidden cycle flagged in review; acyclic under any resolution order.src/dependency-graph.test.tsis the regression check. It models Metro's per-platform resolution (platform ext before.nativebefore generic; each platform graph excludes the other platform's variant files) and asserts (1) zero circular static imports under both iOS and Android resolution — dynamicimport()stays the documented async escape hatch, sostate/use-composer-drafts → lib/attachmentUploadremains a lazy edge, not a static cycle — and (2) shrink-only ceilings on the remaining upward edges (unique module pairs across platforms): state→features 6, lib→features 7, components→features 33, native→features 8, lib→state 11 (lib/runtime.tsis the composition root and counts toward its ceiling). Verified to fail on a seeded Android-only type cycle and on a seeded lib→features import.Follow-up (tracked, not in this PR): the pinned ceiling edges themselves — thread-order→thread-list model, appearance-provider imports from
lib/components, terminal preferences fromlib, native→features glue — each need an owner-side seam and should be lowered opportunistically.No HomeScreen, thread-list, or
package.jsonchanges. The shiki-touch is a 4-line type extraction only — no startup behavior — so it shouldn't collide with the shiki-startup audit item.Verification

Review follow-ups addressed in
8e33b05: Sol audit's Android platform-resolution gap (MaterialSwitch.android.tsxtype cycle) — types extracted, guard now resolves per-platform (iOS + Android) and was verified against that exact seeded mutation; Claude audit's wording note — this PR removeslib → stateupward edges and the dynamic-import round trip rather than claiming a purely static cycle there.Summary by CodeRabbit
