Keep X-Session-ID out of persisted provider headers.
providerConfigSeed() copies staticHeaders into the persisted provider configuration. After a restart, the saved X-Session-ID is treated as a user header, and mergeRegistryStaticHeaders() does not replace it with the new OPENCODE_SESSION_ID.
This makes the identifier stable across process restarts. It conflicts with the declared per-process session behavior. Store this header in a non-persisted runtime-header path, and add a restart regression test that verifies the current process value replaces generated defaults while preserving an explicit operator override.

Test process scope and wire propagation for X-Session-ID.
These assertions prove only that one registry entry contains a string and that one seed copied that value. They do not prove that repeated registry reads return the same process-scoped ID, or that inference and model-discovery requests send the header.
If the session-header change remains in this PR, read the registry entry twice and assert equal IDs. Build representative inference and model-discovery requests and assert that both emit the same X-Session-ID.
As per path instructions, shared routing, adapter, and configuration changes require focused regression coverage near the existing tests. The review stack states that one process-scoped UUID must propagate through provider requests.

Make the session-ID test assert the stated contract.
The test title says the process-scoped session ID replaces a persisted default. Line 220 says the old value should be replaced. Line 227 asserts that the old value is preserved.
As written, this test can pass while a stale generated ID survives a restart. If persisted IDs are intentional user headers, rename the test and comments to say they are preserved. Otherwise, assert the new process value.

Reviewed 3cd5911 against dev@29bb221c3. The current patch and its description disagree materially.
- src/providers/registry.ts:3012/3033 and 3016/3036 declare modelContextWindows and modelInputModalities twice on the same provider. The later DeepSeek-only objects overwrite the added Muse entries at runtime; duplicate object keys are also a TypeScript error. Merge each map once, retaining the existing DeepSeek members.
- This diff also reduces the unrelated Nous discovery cap from 1 MiB to 256 KiB and removes opencode-go.statelessResponses. Please preserve both landed fixes; their existing regression contracts remain in provider-model-discovery-contract.test.ts and opencode-go-luna-wire.test.ts.
- The body says session headers are isolated in #3954, but the generator and X-Session-ID change are present here. It says the Responses sanitizer and exact metadata tests changed, but this exact comparison has no src/adapters/openai-responses.ts change and only a blank-line edit in the provider test. Please correct the branch contents and description, then add actual regression assertions for the final wire/metadata behavior. Do not check verification boxes for changes that are not in this head.
Evidence for the exact free-tier API and capabilities is still needed; a shared family name does not establish identical routing, context or modality policy across tiers. No live restriction probing was performed. This is a source-based request for changes, not a local execution report.
