Walkthrough

The Flows surface test now defines its structural API contract generically over client and caller-descriptor types. It specializes the contract and adds compile-time checks for authentication assignment and spawn parameter types.

Changes: Flows type contract

Layer / File(s)	Summary
Generic API contract and type checks `packages/core-bridge/src/flows-surface.test.ts`	`FlowCoreBridgeApi` now uses generic client and descriptor types, including the descriptor credential type for `authenticate`. Local Flows-shaped interfaces define spawn parameter types. The test specializes the contract with `CoreClient` and `CallerFileDescriptor`, checks an incompatible authentication assignment, and compares spawn parameter types with the local interfaces.

Estimated code review effort: 2 (Simple) | ~10 minutes

_{A rabbit checks the types in flight,
With client and descriptor set just right.
Spawn parameters line up in rows,
While authenticate gets a check that shows.
The Flows contract rests, precise and neat.}

Exact-head verification for b3485906edfedf948081b3a35e7c9097621322a0.

The merged #2133 compatibility gate used interface method signatures, so TypeScript treated method parameters bivariantly. The negative type assertion below proves the corrected function-valued property is doing real contravariant checking.

Mutation: changed only authenticate: (...) => Promise<unknown> back to method syntax authenticate(...): Promise<unknown>.

$ ./node_modules/.bin/tsc -p packages/core-bridge/tsconfig.type-tests.json --pretty false

[Low impact] The PR appears safe to merge; no actionable issues were found.

Summary

Strengthens the Flows compatibility test without changing shipped behavior.

The Flows surface test now checks its copied API shapes with strict input rules.

Successor exact-head verification for 4552c3dce9c6f442c645129d10b21d2315907598.

The prior b3485906e evidence remains valid for the method-bivariance repair. This successor also removes the pre-existing tautology in the three Spawn*ParamsExact assertions: the test now copies the actual Flows #707 parameter shapes independently, uses those copied shapes in the mirrored API, and compares the public Core Bridge types against them.

Gate mutation: changed only copied FlowSpawnInvokeParams.caller_name?: string to required caller_name: string.

$ ./node_modules/.bin/tsc -p packages/core-bridge/tsconfig.type-tests.json --pretty false

Scope remains one test-only file; no runtime implementation or export changed. The prior exact-head review is superseded and a fresh independent review of 4552c3dce is running. Human merge only; no release action.

Independent delegated source audit at exact 4552c3dce9c6f442c645129d10b21d2315907598: CLEAN; no blocking finding. This is evidence for the human reviewer, not an approval or merge action.

The reviewer confirmed the three copied FlowSpawn*Params shapes match both pinned Flows commit 7897907659ce11da0f8fa67015bb7a9426234f4e and the current #707 head. The bridge API consumes those independent copies, and the bidirectional Equal assertions now catch added/removed keys, optionality changes, and union narrowing.

Read-only compiler-host probes changed source only in memory and produced the expected failures:

invoke-extra-key: TS2344 Type 'false' does not satisfy the constraint 'true'.
status-narrow-action: TS2344 Type 'false' does not satisfy the constraint 'true'.
release-optional-id: TS2322 ... is not assignable ...
release-optional-id: TS2344 Type 'false' does not satisfy the constraint 'true'.

Boundary: this remains a manually copied cross-repository snapshot and must move with future Flows shape changes. No clean-pack/product E2E claim is made for this test-only PR.

@willwashburn Human review and merge requested for exact 4552c3dce9c6f442c645129d10b21d2315907598. All hosted checks are terminal green (29 success; only expected skips/neutral bookkeeping), Greptile is green, there are zero review threads, two independent exact-head audits found no blocking issue, and literal method-bivariance plus copied-shape mutation evidence is posted above. Scope is one test-only file; no runtime export or implementation changes. Please review and merge if clean. No release is requested by this comment.
