fix(api): bound complete loopback request receive time - #757
Related to #756. Related to #174; the broader commercialization issue remains open.
Repair
Enforce one monotonic receive budget for complete HTTP headers plus the declared body on both current Naruon and shared Analysis live listeners. Partial progress cannot restart the one-second allowance. A private borrowed-socket adapter installs remaining read time and refuses late successful reads before dispatch. Response-write timeout and all existing framing/authorization/wire limits remain unchanged.
Scope and TDD
This standalone PR contains only eight receive-deadline paths and is based directly on protected baseline a243f18da4a4ca8a8d068c39922537f1f8ed6ad0. It does not inherit or duplicate MLX #755, rustls #538 or central-hourly admission #648.
Four real socket regressions failed before repair (400instead413) across both listeners and both header/body phases. Current API178 test/doctest outcomes and strictClippy pass. Actual rebuilt tepp-loopback rejects slow header/body at about1.06seconds with413, exit0, no stderr; unchanged authorized request positives are covered in the API suite. Test-only exhaustion/partial-read controls verify remaining budget and socket custody. The source-only independent review covers all8 paths and parentverified hashes.
Coverage and execution boundaries
Fresh dedicated-target API line gate 1818/1818(100%) and branch gate 814/814(100%) pass with unchanged repository verifiers. Earlier reused-target line1802/1822 and branch814/970 failures remain preserved; reportcomparison identifies78extra zero-only branch sites in the old cohort, not a production repair or threshold change. Full all-features composition Rust 1454passed/0failed/0ignored, Clippy/rustdoc PASS includes the separate local #538/#648/MLX prerequisites and is not standalone full-policy evidence. Standalone API execution is separately retained.
This does not bound accept waiting, compute, whole-response writing, arbitrary supplied Read, OS scheduling, production authentication, durable processing or GPU scientific parity. Research note traces the I/O contract to actual official Rust docs; no estimator meaning or PRD target is changed.
Promotion requirements
Keep Draft until current-head hosted tests/security/CodeQL and qualifying independent approval pass. Current baseline dependency and retired-cron failures remain independently owned by #538/#648. GitHub-hosted jobs currently report a billing lock before runner allocation; this is not a passed test. Preserve self-hosted migration ownership and normal CI gates. No self-approval, forced history, rerun spam or bypass.

Explanation
PR 제목 "fix(api): bound complete loopback request receive time"은 변경 사항의 핵심을 설명합니다. 변경의 주된 내용은 Naruon 및 Analysis live listener에서 HTTP 헤더와 선언된 본문 전체에 단일 1초 수신 예산을 적용하는 것입니다. raw_summary의 live_http.rs의 DeadlineReader 및 read_socket_request_with_limit 추가, analysis_run_live.rs와 naruon_live.rs의 읽기 경로 변경, 그리고 live_request_deadline.rs의 slow-header/slow-body 회귀 테스트가 이 제목과 일치합니다. 제목은 짧고 구체적이며 conventional commit 형식을 따릅니다. 응답 쓰기 제한, accept 대기 등 범위 밖 항목은 제목에 포함되지 않았으나 이는 제목에 필요한 세부 사항이 아닙니다.

Included review availability: This review used your included allowance. Your plan provides up to 1 included review per hour; 0 remain after this review.
Please perform the normal independent source review of current head 2a40116. This head is a normal non-force merge of current main 4156aff into the previously published df8a576. The merge was conflict-free and the PR still changes the same 8 paths relative to main. On the merged tree with Rust 1.98.0: cargo fmt --all -- --check exit 0, cargo test --locked -p tepp_api exit 0 (21 suites, 178 passed, 0 failed), cargo clippy --locked -p tepp_api --all-targets -- -D warnings exit 0. These are local results, not hosted CI.

The previous request (comment 6734085134) for this same head was rate limited, and the stated included-review wait has now elapsed. This is one follow-up request for the normal independent source review of current head 2a40116, a non-force merge of main 4156aff into df8a576 (8 paths changed relative to main). Local results on this tree (Rust 1.98.0): fmt exit 0, cargo test -p tepp_api 178 passed / 0 failed, clippy -D warnings exit 0. These are local results, not hosted CI.

Included review availability: This review used your included allowance. Your plan provides up to 1 included review per hour; 0 remain after this review.
Connect the client before starting the server timer so accept wait is
excluded, and drip 20 bytes at 150 ms (3 s total) against a 64-byte body.
The one-second budget now refuses with 413 well inside a 2 s bound, while
a per-read timeout that restarts on progress cannot finish before the
3 s drip ends. Addresses CodeRabbit review on 2a40116 (lines 47-50).
Verified locally with Rust 1.98.0: the four regressions pass on this tree
and fail on protected main 4156aff (400 instead of 413).
Please perform the normal independent source review of current head 3415303. The automatic check on this head was skipped because the PR is a Draft. Compared with the previously reviewed head 2a40116, only crates/tepp_api/tests/live_request_deadline.rs changed, answering review thread discussion_r4510340535: the client connects before the server timer starts, the body is a 20-byte drip at 150 ms (about 3 s) against a 64-byte declared length, and the bound is 2 s. Local evidence (Rust 1.98.0, macOS arm64, not hosted CI): the four regressions pass on this head; cargo test --locked -p tepp_api 178 passed, 0 failed; fmt and clippy -D warnings exit 0; the same test file fails all four (400 instead of 413) against main 4156aff with a separate target directory.
Your included review limit is currently reached under our Fair Usage Limits Policy. This review may still proceed through usage-based billing if eligible. Your next included review will be available in 56 minutes.
Comment 6735647310 for this same head 3415303 was rate limited (reply 6735649146: next included review in 56 minutes); that wait has elapsed and no other request was sent in between. Please perform the normal independent source review of current head 3415303, including the test-only repair of the earlier Minor timing finding (thread on crates/tepp_api/tests/live_request_deadline.rs). This is a review request, not a request for approval or merge.
