feat(network): admit and compare typed-text postconditions

[seonghobae]

Scope and preserved lineage

Draft response-bound text-entry intent verification, retaining parent #270 at 8eda96915dbbe4cc617f834267c7464689c2844d. Current head: 46db0045904f0289738df843d0a2f179c26673d3. This is not shipped browser behavior.

The generation-binding regression first failed at 1e600c446e3314b4ec76412b0172c5f1c3430b94 in run 34091736165. The follow-up repairs preserve that boundary and use public session fixtures; 14fb8e7587671faec80ad1c9a4d6076e53f5e69f resolved the fixture visibility build failure.

Current repair and evidence

Run 34151114820 exposed formatting and incomplete production coverage. Both were reproduced locally. Connection and command identity checks still happen before pending-request consumption. Tracing the common immutable response parser proved the post-success duplicate identity check unreachable; only that duplicate was removed.

Real socket tests cover matching, wrong-ID, malformed, remote-error, null-ID, event and foreign-connection replies; rejected sends emit no command bytes or witness. Diagnostics expose neither private text nor fabricated receipts. Existing test helpers are reused; production visibility is unchanged. AGENTS.md, traceability and CHANGELOG are updated.

Frozen-head local verification passes:

• Nine focused integration tests and 148 repository contracts.
• Complete workspace coverage tests: functions 1406/1406, lines 14894/14894, regions 19018/19018, branches 1552/1552 (all 100%).
• Strict all-target/all-feature Clippy, canonical formatting, warnings-denied rustdoc and all five doctests.
• Actual Edge screenshot inspection of the generated acknowledgment documentation: readable contract, no overlap or private-text exposure. This is documentation inspection, not full browser outcome acceptance.

Remaining gates

Exact-head CI run 34186280263 passed both Rust contracts and Production coverage on 46db0045904f0289738df843d0a2f179c26673d3. Both review threads are resolved and GitHub reports the head CLEAN. Keep Draft until parent #270 is adopted through protected main and governing approval rules are satisfied. No tag, release or publication is claimed.

📝 Walkthrough

Walkthrough

WebDriver BiDi typed-input intent와 텍스트 관찰 응답의 상관관계를 추가했습니다. 응답은 동일 연결과 정확한 command id를 검증합니다. 검증기는 expected text와 관찰 결과를 비교하고, page-controlled text를 결과에 저장하지 않습니다.

Changes

Typed-input intent 증명

Layer / File(s)	Summary
Typed-input intent 및 ACK 경계 crates/originweave-network/src/webdriver_bidi_type_text_intent.rs, crates/originweave-network/tests/support/type_text_intent.rs, crates/originweave-network/tests/webdriver_bidi_type_text_intent_postcondition_provenance.rs	Typed-input 명령의 command id, 연결 세대, 검증된 텍스트를 일회성 witness로 보관합니다. ACK는 연결과 command id가 일치할 때만 생성합니다.

텍스트 관찰 응답 투영과 상관

Layer / File(s)	Summary
Bounded 응답 투영과 command correlation crates/originweave-network/src/webdriver_bidi_text_value_observation_response.rs, crates/originweave-network/tests/support/text_observation.rs	script.callFunction 응답의 envelope, 이벤트, protocol error, script exception, string RemoteValue를 판별합니다. JSON member, 문자열, nesting, 중복 member와 크기 제한을 검증합니다.
WebSocket 경계 및 fail-closed 테스트 crates/originweave-network/src/webdriver_bidi_text_value_observation_public_boundary_tests.rs, crates/originweave-network/tests/webdriver_bidi_text_value_observation_correlation.rs, crates/originweave-network/tests/webdriver_bidi_text_value_observation_response.rs, crates/originweave-network/tests/webdriver_bidi_text_value_observation_unicode_response.rs, crates/originweave-network/tests/webdriver_bidi_text_value_response_fail_closed.rs	동일 연결의 응답만 outstanding command를 소비합니다. 교체 연결, 잘못된 envelope, 이벤트, protocol error, script exception, 잘못된 projection과 escaped Unicode 응답을 검증합니다.

Postcondition 결과와 공개 경계

Layer / File(s)	Summary
Postcondition 검증 및 값 없는 결과 crates/originweave-network/src/webdriver_bidi_text_value_postcondition.rs, crates/originweave-network/src/lib.rs, crates/originweave-network/tests/webdriver_bidi_text_value_postcondition_gate.rs	ACK된 intent의 expected text와 관찰 결과를 비교합니다. 일치하면 command id와 관찰 byte 수만 반환합니다. 불일치하면 PostconditionMismatch를 반환하고 관찰 텍스트는 저장하지 않습니다.
문서와 계약 테스트 CHANGELOG.md, docs/doctoring/browser-agent-protocols.md, docs/traceability/action-postcondition-evidence.md, tests/test_product_documentation_contract.py	동일 연결 제한, typed text-value postcondition, page-controlled text 폐기와 PostconditionMismatch 동작을 문서와 changelog에 기록합니다. 문서 계약 테스트가 해당 내용을 확인합니다.

Estimated code review effort: 5 (Critical) | ~90 minutes

Merge Risk: 🟡 Moderate · up to af1de

A replacement connection may certify text against an earlier typed-input acknowledgement, and the formatting gate remains failing. Both should be resolved before merge.

Writer lease ACTIVE — bounded review repair on exact current head af1defe84a9edcd3047584c297d5acd3ec40acc4, parent #270 8eda96915dbbe4cc617f834267c7464689c2844d. Fresh review exposes two still-valid findings: canonical rustfmt drift in the new intent slice, and a security provenance gap because the acknowledged TypeText intent drops its connection generation, allowing an identical text observation from another verified connection to satisfy the post-condition. Scope: add a realistic cross-connection regression that preserves the pending observation, retain the acknowledged intent generation, reject generation mismatch before observation correlation is consumed, apply canonical formatting only to affected files, then inspect exact-head checks and release. No workflow/ruleset/secret/gate/approval/merge/tag/release mutation.

[seonghobae]

TDD checkpoint — published test-only exact head 1e600c446e3314b4ec76412b0172c5f1c3430b94 by ordinary fast-forward over repaired predecessor af1defe84a9edcd3047584c297d5acd3ec40acc4. The new real-loopback regression creates the acknowledged TypeText intent on connection A, creates an identical-value script.callFunction observation on independently verified connection B, and requires that B neither certify the earlier intent nor consume its pending observation. No production code changed. Fresh exact CI 34091736165 exists but is still pre-checkout queued: coverage 101646467148, Rust 101646467369, both runner_id=0, steps=[]; therefore the new cross-connection defect has not yet produced an executed RED, and the minimal generation-binding fix remains intentionally withheld under AGENTS.md. The rustfmt-only review finding is partially normalized in the edited regression, but the remaining affected source/test formatting will be fixed together with the causal repair after RED. No predecessor GREEN transfer, blind retrigger, workflow/ruleset/secret/gate mutation, merge, tag, or release.

[seonghobae]

Cross-connection post-condition RED writer RELEASED — published exact test-only head 1e600c446e3314b4ec76412b0172c5f1c3430b94, unchanged parent #270 8eda96915dbbe4cc617f834267c7464689c2844d, by normal fast-forward. The new real-loopback regression separates the acknowledged TypeText transport from an independently verified observation transport, uses the same textual value, requires cross-connection evidence to fail, and requires the pending observation correlation to remain unconsumed. PR body was repaired to the actual current head and the second CWE-345 finding; predecessor af1defe... remains historical production evidence only.

Fresh exact CI 34091736165 is still pre-checkout queued: Production coverage 101646467148 and Rust contracts 101646467369, both steps=[], runner_id=0. Therefore the cross-connection regression has not yet produced an executed RED and no production generation-binding repair was made. The current queue evidence was handed to .github#712; no no-op/rerun, workflow/ruleset/secret/gate mutation, self-approval, merge, tag or release occurred. The still-valid rustfmt review finding remains unresolved and will be repaired together with the causal generation binding after executed RED. No #271 source/docs/ref writer remains with this task.

[seonghobae]

Writer lease ACTIVE — hourly commercial loop. Sole source/docs writer is now bounded to #271 exact test-first head 1e600c446e3314b4ec76412b0172c5f1c3430b94 on feat/webdriver-bidi-type-text-postcondition-response. Scope: preserve the already-executed cross-connection CWE-345 RED; retain the acknowledged TypeText connection generation privately; reject foreign observation generation before correlation consumption; keep raw text and generation identifiers out of public evidence/Debug/errors; apply canonical rustfmt and obtain focused/full exact-head verification. No force/rebase, workflow/ruleset/secret/gate, self-approval, protected merge, tag, or release mutation.

[seonghobae]

Causal repair published non-destructively. Current exact head is a31971b10042fcb6404a06c18c6c3150794d7f2e on unchanged prerequisite #270 8eda96915dbbe4cc617f834267c7464689c2844d. The acknowledged TypeText intent now retains its private connection generation; post-condition verification rejects an observation from another generation before lower response correlation can consume pending state. The typed ObservationConnectionMismatch error exposes neither raw text nor the generation identifier, and the realistic foreign-connection regression now requires that exact failure plus outstanding-correlation preservation. Canonical rustfmt output from the executed RED run was applied to the previously identified files. Fresh exact-head CI 34146087725 is currently queued (Production coverage 101818327262; Rust contracts 101818327308), so no GREEN claim is made yet. The existing Unreleased CHANGELOG already states this buyer-visible replacement-connection rejection; no duplicate changelog entry was added.

[seonghobae]

Current exact head advanced non-destructively to 33731d05d17257397761a368bcee666d38604316 after reviewing the causal fix against the existing post-condition fixtures. The first generation-binding repair correctly made the old positive/mismatch/lower-error fixtures invalid because those helpers created the TypeText ACK and observation on separate WebSockets. That was test-fixture debt, not a reason to weaken the production invariant. The fixtures now exercise TypeText ACK → fixed script.callFunction observation on the same actual loopback WebSocket with distinct client masking keys; the dedicated CWE-345 regression alone deliberately uses independently verified connection B and requires ObservationConnectionMismatch before pending correlation is consumed. The value-substitution regression also stays on one connection so it tests value authority independently of connection provenance. Fresh exact-head CI is 34146645486 (coverage 101820022778, Rust 101820022823); both jobs remain pre-run queued, so no passing evidence is claimed.

[seonghobae]

Writer lease RELEASED — current source checkpoint is exact 33731d05d17257397761a368bcee666d38604316 on unchanged prerequisite #270 8eda96915dbbe4cc617f834267c7464689c2844d. The executed CWE-345 RED has a minimal generation-binding production repair plus realistic same-connection positive fixtures and a deliberately foreign-connection negative fixture. Exact-head CI 34146645486 is still pre-run queued, so this is a handoff checkpoint rather than GREEN acceptance. No source/docs/refs authority is retained across the wait; the next writer must reacquire fresh authority, read intervening deltas, and treat this run as non-passing until those exact jobs actually execute.

[seonghobae]

Writer lease ACTIVE — bounded PR-state doctoring only at exact source head 33731d05d17257397761a368bcee666d38604316. Scope: replace the stale test-only PR description with the actual generation-binding repair checkpoint and current exact-head CI state; preserve Draft, #270 prerequisite, source/refs, historical conversation evidence, unresolved review findings, and all gates. No source/docs/workflow/ruleset/secret/approval/merge/tag/release mutation.

[seonghobae]

Writer lease RELEASED — PR-state doctoring complete. #271 remains Draft/open on exact 33731d05d17257397761a368bcee666d38604316 over #270 8eda96915dbbe4cc617f834267c7464689c2844d. The description now reflects the actual generation-binding production repair, same-connection positive fixtures, deliberately foreign-connection CWE-345 regression, unresolved review state, and exact CI 34146645486 as pre-run queued rather than transferring predecessor evidence. No source/refs/gates/reviews were changed by this lease.

[seonghobae]

Writer lease ACTIVE — root task 01a06c0f-b427-7830-b654-9addcdfe7aff, bounded repair from exact 33731d05d17257397761a368bcee666d38604316. Fresh hosted CI 34146645486 has executed: Rust contracts fails canonical rustfmt; coverage fails compilation because integration-test support calls crate-private register_command_for_connection and private connection-generation evidence (E0624). Scope: repair only those executed gate failures without widening production visibility, using the existing public typed session.status sender for the unrelated-command fixture, canonical-format affected Rust, publish non-force, then inspect exact-head CI and RELEASE. #270 exact base 8eda96915dbbe4cc617f834267c7464689c2844d remains untouched. No workflow/ruleset/secret/gate/approval/merge/tag/release mutation.

[seonghobae]

Writer lease RELEASED — bounded executed-gate repair published at exact 14fb8e7587671faec80ad1c9a4d6076e53f5e69f. The predecessor 33731d... E0624 integration-test visibility defect is repaired without widening production API: the unrelated-command fixture now uses public typed WebDriverBiDiSessionStatusCommand on the same actual connection, and the file is based on the canonical rustfmt artifact from job 101820022823. Exact CI 34151114820 is queued, so this is not a GREEN claim. Keep Draft/review threads unresolved until exact-head Rust contracts and enforced production coverage execute successfully.

[seonghobae]

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.

[seonghobae]

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.

[seonghobae]

Writer lease RELEASED: published exact 46db004 over unchanged #270 8eda969. Removed only the proved-unreachable post-correlation duplicate; kept pre-consumption connection/id guards. Real ACK/privacy and sender rejection tests plus existing postcondition tests pass (9 focused); 148 repository contracts, canonical rustfmt and strict Clippy pass. Full local coverage is F1406/1406, L14894/14894, R19018/19018, B1552/1552, all 100%. Dependency-inclusive rustdoc/doctests are still executing locally; hosted run 34186280263 is queued. Keep Draft and both review threads unresolved pending exact-head hosted acceptance. No production provenance visibility changed; no merge/release.

[seonghobae]

Verification completed for published 46db004: warnings-denied rustdoc and all five doctests pass, alongside previously reported full 100% coverage, 9 focused integration tests, 148 repository contracts, strict Clippy and formatting. Actual isolated Edge screenshot inspection confirms readable generated acknowledgment documentation; this is not real browser outcome acceptance. Exact-head hosted run 34186280263 and both jobs are still queued. Keep Draft and both review threads unresolved until authoritative verification satisfies the gates. Source writer lease remains released.

[seonghobae]

Exact-head lifecycle refresh: CI 34186280263 is terminal SUCCESS for 46db004. Rust contracts 101935137010 and Production coverage 101935137169 both passed; both review threads are resolved and GitHub now reports CLEAN. The PR remains Draft because parent #270 is not yet adopted through protected main and independent governance gates still apply. No merge or release claim.
