Explanation
The description follows the required Summary, Impact, Testing, and Notes sections. It explains the implementation, user and maintainer impact, focused tests, validation results, and the incomplete full check with documented context.
Full details: Risk Surface Disclosed
-
Explanation
PASS. The PR changes provider routing and outbound request behavior by applying per-session environment variables, including provider endpoints and credentials. The PR description explicitly discloses the risk: sessions could silently use the wrong endpoint or account, and env-less turns can observe another turn’s process environment. It also documents the process-wide mutex, serialization, deadlock cases, default behavior, and the lack of provider/network-path coverage. The stated impact is no default user-facing change, so no blocker is identified.
Full details: No Hidden Policy Change
-
Explanation
No hidden policy change found. The PR changes only the v2 SDK option/type, v2 turn scoping, and focused tests. The routing change is explicit:
SDKSessionOptions.envapplies provider-selection variables per turn, serializes env-scoped turns, and documents env-less visibility. Existing permission options and callbacks remain unchanged. No telemetry, network instrumentation, trust-model, or permission-policy code changes appear in the reviewed diff.

Test the turn lifecycle, not only the private hooks.
These tests never iterate sendMessage(). They cannot detect a failure to apply the environment before a turn or restore it after an early exit. Add a focused turn-level test that observes the environment during iteration and after the consumer breaks. Include a concurrent env-less turn to check isolation.
As per path instructions, “Block when risky runtime changes lack focused regression coverage or tests assert implementation details while missing the user-visible behavior.”

Done in bddb9b5 — and it found a second thing, so thank you.
src/entrypoints/sdk/v2.sessionEnvTurn.test.ts iterates sendMessage(). The engine is a stand-in that pushes process.env[KEY] into a list for every message it yields, so the assertion is on what the turn actually saw rather than on the hooks; init is stubbed, because the real one configures proxies, mTLS and remote managed settings process-wide and reaches the network.
Three tests: the turn sees its own variables and nothing is left afterwards; an abandoned iterator (break on the first message) puts the environment back and frees the mutex, proven by a second turn getting straight in; two turns with different environments never interleave, checked on what each engine saw rather than on timing.
Writing the first of those showed the apply was in the wrong place. It ran before init(), while query() deliberately applies after it (SEC-1) — init is memoized and sets up the global agents, the proxies and mTLS once per process, so the first session to run was configuring all of it out of its own variables. The apply moved inside the generator, right after init, with the restore in a finally around the rest of the turn.
On the env-less concurrent turn you asked for: it would be a test of something this PR does not provide, so it is not there — see the top-level comment.
Red-first: with v2.ts reverted to main and both test files kept, the two files are 0 pass / 8 fail.

Review follow-up: three findings fixed in bddb9b5, one declined with a reason. Full local preflight re-run, all green except the documented Fixed — the mutex could be held by a turn that never started. Fixed — the snapshot has a null prototype. Fixed, and not what was reported — the apply was on the wrong side of Declined — isolating env-less turns. The finding is accurate: a turn belonging to a session with no What this PR does instead is say so in the type rather than leave it to be discovered: * What it does NOT do, exactly as in `query()`: a turn belonging to a
* session without `env` takes no mutex, so it can run while another
* session's variables are in place. In one process there is one
* environment; isolating readers as well as writers would mean serialising
* every turn in the process. So set `env` on every session that cares which

📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value
Verify Object.entries cannot diverge from the snapshot keys.
The snapshot loop uses Object.keys(overrides), and the apply loop uses Object.entries(overrides). A plain host object gives both loops the same key set. A Proxy can return different keys from separate enumerations, and the restore step then misses the extra key. Hosts that pass a Proxy for env are unusual, so this is non-blocking. If you want to remove the gap, enumerate once:
♻️ Single enumeration

- snapshot[key] = process.env[key]

`QueryOptions` accepts `env`; `SDKSessionOptions` did not, so a host that keeps several sessions alive in one process had to share one environment between them. That matters when the variable selects the provider. `ANTHROPIC_BASE_URL`, `OPENAI_BASE_URL` and the matching keys are read per request, so two sessions aimed at different endpoints silently used whichever had been set last — and the symptom is not an error but an answer from the wrong place, or billing against the wrong account. Applied around each turn and restored afterwards, reusing the process-wide env mutex `query()` already takes (SEC-1), so one session's variables cannot leak into another session's turn. The wrapping sits around the whole iteration rather than inside the generator, so a consumer that breaks out of the loop still restores: the generator's return runs the finally with it. A session that sets no `env` takes no mutex and costs nothing. The mutex means turns belonging to sessions with different environments serialise rather than overlap. With one process environment there is no honest alternative, and serialising is the behaviour that is correct rather than merely concurrent; the type documents it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…on failure Review follow-up on the placement and on two ways the lock could be kept. APPLIED AFTER init(), INSIDE THE GENERATOR. `query()` takes the mutex and applies its overrides after `init()` for a reason: `init` is memoized, and it configures the global agents, the proxies and mTLS once for the process. Doing it before meant whichever session happened to run first configured all of that out of its own variables. The apply now sits where query's does — right after init, with the restore in a `finally` around the rest of the turn. An early exit still restores. That was the stated reason for wrapping `yield* inner` instead, and it was not a reason: a consumer that breaks out of the loop calls the generator's `return`, which runs the generator's own `finally` — the way the same pattern already works in `query()`. THE MUTEX IS RELEASED IF APPLYING THROWS. `Object.entries(overrides)` invokes getters, so an `env` whose properties are accessors could throw after the lock was taken and before `sendMessage` entered its `try`. The lock stayed held and every later env-setting turn in the process waited on it forever. Application is now wrapped: what was already applied goes back and the lock is released before the error leaves. THE SNAPSHOT HAS A NULL PROTOTYPE. `__proto__` is a variable name like any other, and on a plain object `snapshot['__proto__'] = value` is swallowed by the prototype setter instead of being remembered — so the one key that must be restored would be the one key missing from `Object.keys(snapshot)`. The tests now drive `sendMessage()` itself, not only the private apply and restore: the engine is a stand-in that reports what it sees in `process.env`, and `init` is stubbed because the real one reaches the network. They prove the variables are in place when the engine asks, that an abandoned iterator puts them back and frees the lock, and that two turns with different environments never interleave — three tests, all five of the earlier ones kept, red against main (0 of 8). Documented in the type what this does NOT do, since it would otherwise be found out instead: a turn of a session without `env` takes no mutex, exactly as in `query()`, so it can run while another session's variables are in place. Isolating readers too would mean serialising every turn in the process. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…ld all turn Review follow-up. Holding the environment mutex for the whole turn is what makes the isolation real, and it has two consequences a host author would otherwise meet as a hang: A PAUSED ITERATOR STILL HOLDS IT. Stopping half way through `for await (… of session.sendMessage(…))` to await another env-carrying turn waits forever: the first turn cannot finish while the second waits for the lock it holds. Finishing the turn, or leaving the loop with `break`/`return` — which calls the generator's `return` and frees the lock — is the way out. A `canUseTool` CALLBACK IS INSIDE THE TURN. Awaiting an env-carrying `query()` from it is the same deadlock one level down. Both are documented on the option rather than discovered. Neither applies to a session without `env`, which takes no lock at all. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…rn sees Three findings from review. Object.keys fed the snapshot loop and Object.entries the apply loop. A plain host object gives both the same keys; a Proxy need not. A key seen only by the apply loop would be set and never restored. Enumerated once now, and before the mutex is taken, so a throwing getter cannot leave it held either. mock.module registrations are process-global and mock.restore does not remove them, so the stubbed init() went on standing in for the real one in every test file that ran afterwards in the same bun process. The real module is captured first and re-registered in afterAll. The review also asked for a concurrent env-less turn, expecting isolation. There is none, and the test now says so: a turn that sets no environment takes no mutex, so it runs alongside one that does and reads the same process.env while the variables are in place. Serialising every turn instead would stall an embedder's whole process the moment one session used env. What does hold — that nothing survives the turn — is asserted, and the limit is documented on SDKSessionOptions.env. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

321-353: Non-blocking: the null-prototype snapshot and single enumeration address the earlier findings.
Object.entries(overrides)runs beforeacquireEnvMutex(), so a throwing getter cannot leave the mutex held. The null-prototype snapshot keeps__proto__restorable. This matches the retrieved learning aboutObject.create(null).If
acquireEnvMutex()is the only await between the check and the apply, the ordering is correct. A cancelled turn cannot leak the lock, becauserestoreSessionEnvruns in thefinallyblock.One edge case remains.
process.env[key] = valuecoerces non-string values to strings. This is acceptable because the type isstring | undefined.
396-502: Verify the lock is released if the generator is closed before the firstnext()completesapplySessionEnv.
applySessionEnv()is awaited at Line 396, before thetryat Line 397. If it rejects, the error path already restores and releases insideapplySessionEnv. If it resolves, thetry/finallyowns the restore. This is correct.A generator that is never iterated never reaches this code, so it takes no lock. This is also correct.

Add a provider-boundary assertion.
src/entrypoints/sdk/v2.sessionEnvTurn.test.ts:70-88 replaces the session engine with engineSeeingEnv, which only reads process.env and yields synthetic messages. The tests do not create a provider client or assert its endpoint or credentials.
A regression where sendMessage() applies the environment but the provider route or client ignores it would therefore pass. Add one focused turn test that reaches the provider request and asserts the overridden endpoint or authentication header. Existing provider tests exercise lower-level query paths, not this SDK session boundary.

bun run checkcould not be run to completion, for the reason already documented on fix(sdk): follow switchSession with the session file pointer #2253 and reproduced again here: itstest:fullstep stops making progress and spins a single core with no output.

Every step ofcheckthat does finish was run individually and passes (above), and thesrc/entrypoints/sdksegment is green.Notes
provider/model path tested: none — this is provider-independent plumbing. The tests drive the apply/restore directly and run no turn, so there is no network and no provider key involved.
screenshots attached (if UI changed): n/a, no UI change.
follow-up work or known limitations: this does not make turns with different environments concurrent, and cannot: one process has one environment. What it removes is the silent case, where two sessions shared a provider address neither of them asked for.
Nor does it isolate turns of sessions that set no
env— they take no mutex, exactly as inquery(), so one can run while another session's variables are in place. The type now says so. Closing that would mean every turn in the process taking the environment lock, i.e. all SDK turns serialising, forquery()as much as for v2; that is a maintainer's call rather than part of addingenvto a type.Related: Transcript state on the Project singleton is not isolated per SDK context #2267 tracks a separate isolation gap in the same area —
