Verified against the executed RED and repaired on the current branch. The rustfmt delta identified by exact-head job 101646467369 was applied first to the three original files; the same-connection fixture repair added afterward is now awaiting canonical exact-head CI at 33731d05d17257397761a368bcee666d38604316 (run 34146645486).

Exact-head execution has now resolved the queue state: CI 34146645486 completed failure on 33731d05d17257397761a368bcee666d38604316. Rust contracts 101820022823 passed all 148 Python repository contracts, then failed cargo fmt --all --check; workspace check/tests/Clippy/rustdoc were skipped. Current source still shows canonical-rustfmt deltas, including the return-type brace in acknowledge_webdriver_bidi_type_text_intent and both test function signatures in webdriver_bidi_type_text_intent_postcondition_provenance.rs. Keep this thread unresolved and apply the canonical formatter as an ordinary current-head repair rather than inheriting the earlier formatting claim. Production coverage 101820022778 independently failed during the measurement step, so the next writer must RCA that failure separately after formatting; neither failure is current-head GREEN.

@seonghobae, acknowledged. The current exact-head CI did not pass cargo fmt --all --check.

Verified and fixed from the behavioral RED. WebDriverBiDiAcknowledgedTypeTextIntent now privately retains the sender/ACK connection generation, and verify_webdriver_bidi_text_value_postcondition rejects a foreign received generation before observation correlation can consume pending state. The regression requires the typed non-sensitive ObservationConnectionMismatch, retains the foreign observation pending, and checks that raw text is absent from Debug/error diagnostics. Positive/mismatch/lower-error fixtures were also repaired to keep TypeText ACK and observation on the same actual loopback WebSocket, so they do not pass by bypassing the new invariant. Current exact head is 33731d05d17257397761a368bcee666d38604316; exact-head CI 34146645486 is still queued, so I am leaving this thread unresolved until GREEN is observed.

@seonghobae, thanks for the detailed update.
The reported change addresses the connection-generation binding requirement. The regression also checks that a foreign observation does not consume pending correlation state.
Exact-head CI 34146645486 is still queued. Keep this thread open until that run is green.

Learning: In `crates/originweave-network`, `WebDriverBiDiAcknowledgedTypeTextIntent` must retain the private connection generation from the sender-minted typed-text intent. `verify_webdriver_bidi_text_value_postcondition` must reject an observation received on a different connection generation before it consumes observation correlation state. Public diagnostics, errors, and `Debug` output must not expose the observed or expected text.

The generation-binding production repair is present on current exact 14fb8e7587671faec80ad1c9a4d6076e53f5e69f, but this thread still cannot be cleared: exact CI 34151114820 is terminal FAILURE. Production coverage 101833427858 measures successfully and then fails exact enforcement; its artifact 10029489840 shows uncovered production paths confined to webdriver_bidi_type_text_intent.rs, including the new acknowledgement error/privacy surface. A separate exact-head review (5134997263) also identifies the post-correlation second command-id mismatch check as structurally unreachable after the pre-consumption envelope check plus typed correlation. Keep this thread unresolved until the reachable paths are covered, that dead duplicate branch is removed rather than synthetically forced, canonical rustfmt passes, and a fresh exact head is fully GREEN.

Keep this thread open. The generation-binding repair is present, but exact CI 34151114820 failed.
Remove the structurally unreachable post-correlation command-id mismatch branch. Cover the remaining reachable production paths in webdriver_bidi_type_text_intent.rs. Run canonical rustfmt. Then validate a new exact head with fully green CI.

Exact-head follow-up on 14fb8e7587671faec80ad1c9a4d6076e53f5e69f: CI 34151114820 is terminal FAILURE, not queued. Rust contracts 101833428065 again fails cargo fmt --all --check; Production coverage 101833427858 completes measurement and diagnostics, then fails exact coverage enforcement.
The uploaded exact coverage artifact 10029489840 (sha256:bcd07fe37515a89998f51abe0a9101f9ba3a5d22061daf2c24de83d829bb0b66) localizes all uncovered production lines to crates/originweave-network/src/webdriver_bidi_type_text_intent.rs. The missing paths include both opaque Debug implementations; stable Display/Error::source behavior for WebDriverBiDiTypeTextIntentAcknowledgementError; sender-delegated failure; foreign-connection ACK; malformed envelope; remote/error/event admission; and command-id mismatch handling. Those are owned production paths and need realistic or direct boundary coverage rather than a threshold exception.
One branch should not be covered by manufacturing an impossible fixture: after the pre-correlation envelope check rejects every Some(command_id) different from the witness, WebDriverBiDiTypeTextResult::parse_and_correlate can return Ok only from the same success envelope and returns completed.command_id() for that response. Event/null-id/error inputs cannot produce that Ok. Therefore the later if result.command_id() != witness.command_id { ResponseCommandMismatch } branch is structurally unreachable under the preceding invariants. Keeping it forces 100% coverage toward a parser/correlation invariant violation. Minimal repair should remove that redundant post-correlation branch, retain the pre-consumption command-id check, and add coverage only for reachable error/privacy paths. Do not widen private connection-generation visibility or add synthetic malformed-success construction solely to hit the dead branch.
Keep Draft and both current review threads unresolved until canonical rustfmt plus focused/full tests, strict Clippy, rustdoc, and exact production coverage are GREEN on a fresh exact head.

Writer lease ACTIVE: exact 14fb8e7, unchanged #270 parent 8eda969. Reproduced canonical formatting failure locally and revalidated exact hosted coverage artifact 10029489840. Scope: remove only the unreachable post-correlation duplicate after confirming the lower correlation invariant, cover reachable sender/ACK/privacy failures using real loopback receipts and existing test fixtures, retain pre-consumption id/generation checks, then run complete exact coverage and inspect visual API documentation. No production visibility expansion or review/gate bypass. |

14fb8e...repairs only those executed gate failures. It starts from the canonical rustfmt artifact produced by the failed Rust job and removes the integration-test reach-through instead of widening production visibility. The unrelated-command fixture now sends a real public typedWebDriverBiDiSessionStatusCommandon the same established RFC 6455 connection with its own masking key; the loopback peer reads that command before returning the unrelated response.response_kindremains constrained toSessionStatus, so this support helper is not a generic arbitrary-command escape hatch.Buyer-visible contract
Typed-text post-condition evidence is positive only when the reviewed TypeText sender minted the one-shot intent, its exact protocol ACK was admitted on the same verified WebDriver BiDi connection, the fixed product-owned text observation was sent and correlated on that connection, and the observed page string exactly matches the retained authorized text. Command ACK, parser success, matching text supplied at verification time, or matching text observed on another connection is not browser-state success.
The public success value carries only the typed-input command id, observation command id, and observed UTF-8 byte count. Page-controlled text, expected text, connection-generation identifiers, realm identifiers, credentials, browser authority, and policy authority are not retained in the evidence/error surface. MCP/LLM adapters do not participate in this deterministic browser-domain decision.
