Initial exact-head review on b965eceacbd1c00163ac380d9fe406a3bff901f2. Fresh compare against #77 exact 0d583374607f32876fa17ef0501a8a548fb074f1 is ahead-only by one commit and one new test file. The fixture sends two live requests on one verified TLS/H2 connection, waits for the sibling response to prove both origins were dispatched, then sends RST_STREAM(CANCEL) on stream 1 and requires stream 3 to complete without reset while the cancelled stream's dedicated H1 origin connection reaches EOF/reset within a 3 s bound. Production Rust/config/routing/TLS/security authority is unchanged. No source-level weakening or predecessor GREEN transfer found. COMMENT only; exact CI/Supply Chain/capacity are queued, so protocol/fixture GREEN is not claimed yet.

Exact-current repair review on 13f2520249169f18644094e244c7133ae375c35a. Predecessor b965eceacbd1c00163ac380d9fe406a3bff901f2 reached exact CI job 103146794775, which stopped at cargo fmt --all -- --check before compile/test. The emitted diff only wrapped the two terminal assert! calls for reset_sent and sibling_ended; no protocol behavior, timing threshold, H2 frame, origin-release oracle, production Rust/config, or authority boundary changed. Current exact applies precisely that rustfmt output. Fresh CI 34562439644, Supply Chain 34562439646, and capacity 34562439638 have been created and predecessor execution does not transfer. COMMENT technical evidence only; keep Draft until exact-current execution terminates and any RED is classified.

The fixture has a valid concurrency barrier. The origin sends I found two issues in the reset evidence.

Documentation-current review on exact c1457d240b5c921fabf2525ff70f04aab85be7e9. Predecessor 13f2520249169f18644094e244c7133ae375c35a is now terminal GREEN across CI 34562439644, Supply Chain 34562439646, and PgErd capacity 34562439638; its compile/test lane executed the real-wire RST_STREAM(CANCEL) fixture successfully. The current ordinary-forward commit changes only docs/doctoring/DOWNSTREAM_TLS_HTTP2_TRACEABILITY.md, binding RFC 9113 reset/CANCEL semantics, the exact #78 RED→formatter repair→GREEN chain, and the remaining GOAWAY/flow-control/supplier/promotion boundaries. No production Rust, test oracle, workflow, dependency, timing threshold or authority boundary changed. Because the exact head moved, predecessor GREEN does not transfer; fresh CI 34563105324, Supply Chain 34563105342, and capacity 34563105323 must terminate on this head before Ready/promotion credit. COMMENT technical evidence only; not independent approval.

I found one documentation-evidence mismatch.
The supplier boundaries and remaining promotion gaps are otherwise consistent with the stated scope. The diff is documentation-only, and the real-wire fixture is unchanged from The exact-current CI, Supply Chain, and PgErd checks are still nonterminal. I did not treat the GREEN receipts for ✅ Action performedReview finished.

- Line 359: Update the sibling cancellation test so the origin-release timer
starts only after the client’s RST_STREAM(CANCEL) flush completes: signal flush
completion through a one-shot channel, then call
require_cancelled_origin_release for the origin thread. Apply the same ordering
to both affected call sites while preserving the existing cancellation
assertions.
- Line 414: Update the stream 3 frame handling so sibling_response_started is
set only when a HEADERS frame is received, not for control frames such as
WINDOW_UPDATE. Preserve the existing cancellation flow while ensuring stream 1
is cancelled only after the sibling response has actually begun.

Exact-head technical review for 9731fc3cfe80e25e03983a9b65c67aaea3e69db3 (not an approval). I traced CI 34563105324 to the llvm-cov-only failure in the pre-existing pg-erd protocol-transition fixture: the strict Upgrade acceptance itself still requires HTTP/1.1 501 and untouched origins, but startup had used successful bare TCP connect as the readiness oracle. The current patch keeps the acceptance strict, makes readiness a bounded complete /readyz/200 transaction, shares the finite whole-header reader, and holds reserved traffic/metrics sockets until immediately before spawn. No production Rust, routing, TLS, supplier, or authority semantics changed. Fresh exact gates must terminate before Ready/merge credit.

Exact-head technical review for 441725515442c5f592134eb6ece8245be0c9f0d6 (not an approval). The llvm-cov-only failure on predecessor c1457d... was unrelated to the H2 reset/sibling oracle: the existing protocol-transition fixture entered strict 501 acceptance after bare TCP listen evidence and still had the already-proven sibling ephemeral-port handoff race repaired on #74. Current exact keeps the strict 501 + untouched-origin contract, adds bounded /readyz/200 application readiness, holds both reserved sockets until spawn, and adopts #74's process-local mutex/poison-recovery serialization around only the two real-listener handoffs. No production Rust, TLS/routing, supplier, or product/security authority changed. Fresh exact gates must terminate before Ready/merge credit.

Exact-head technical review for b4c54e22c252aa99a19b2b90881343653c6aa995 (not an approval). Two CodeRabbit Major findings were valid and are repaired rather than dismissed: the cancelled-origin release timer is now causally anchored after the client has flushed RST_STREAM(CANCEL) through a one-shot channel, and sibling response start is recognized only from stream-3 HEADERS rather than arbitrary control frames. Both corresponding review threads are now resolved. The existing application-readiness/listener-handoff repairs remain intact; production Rust and gateway authority boundaries are unchanged. Fresh exact gates are required before Ready/merge credit.

0d583374607f32876fa17ef0501a8a548fb074f1.This PR adds the real-wire HTTP/2 reset/sibling-survival acceptance without changing production Rust, Admin Config, TLS/cipher policy, routes/retries, product auth/business logic, Keyverse/Wardnet/EgressWeave authority, supplier source or deployment authority.
The fixture opens two streams on one certificate-verified
h2connection. Stream 1 remains pending at its dedicated H1 origin while stream 3 begins a normal response only after both origin requests have been observed. Once stream 3 HEADERS have actually arrived, the client sends and flushesRST_STREAM(CANCEL)for stream 1. A one-shot channel then starts the cancelled-origin release timer only after that flush. Acceptance requires stream 3 to survive without reset and finish with exact bodysibling-ok, while the cancelled stream's dedicated origin connection is released within the bounded three-second post-reset evidence window. A serialized implementation cannot manufacture GREEN because the origin refuses to expose the sibling response until both requests have been dispatched.Earlier exact

RCA had two coupled harness causes: bare TCP listen was incorrectly used as application readiness, and the file still lacked the sibling ephemeral-port handoff serialization already proven on #74.9731fc3c...added bounded complete/readyz/200 readiness and held traffic/metrics reservations until child spawn;4417255...adopted #74's process-local mutex/poison-recovery serialization without weakening the strict exact-501/untouched-origin acceptance.Fresh review then produced two valid Major findings on the H2 cancellation fixture itself.

b4c54e22c252aa99a19b2b90881343653c6aa995repairs both causally: release timing is gated by a channel sent only afterRST_STREAM(CANCEL)flush, and only stream-3 HEADERS can trigger cancellation.
