Valid observability evidence gap

The shared observability bounded context intentionally exposes only low-cardinality transport completion facts. The dedicated cwl-pingora-pg-erd-migration process therefore needs real-listener proof that request path/query, Host, Authorization, Cookie and product-context values are actually forwarded while none enter shared observability output. This remains gateway observability evidence only; it does not claim product logging, tracing, Keyverse identity, or Wardnet/EgressWeave policy authority.

Parent and retained repairs

Final #22 3db4fe08e3c2145559ea01b01598a028d0be798b is hosted/technical GREEN. #23 was ordinarily/non-force restacked on that parent through two-parent e204e5ca08bc57f7b5210da9bb78868706be7504, resolving from the final #22 tree and reapplying only the valid child delta. Effective scope remains exactly four paths: CHANGELOG.md, TEST_STRATEGY.md, docs/product-technical-gap-baseline.md, and tests/pg_erd_payload_free_observability.rs.

The fixture retains concurrent traffic/metrics listener reservations, five-second/64 KiB origin request bounds, exact case-insensitive HTTP field-name parsing with OWS trimming, exact Prometheus sample-line matching, exact case-sensitive request-target matching, exact bounded completion-message matching, and complete captured-stderr sentinel exclusion.

Review / hosted RED → repair lineage

Predecessor 89aa2940ad8f6705610f050f9a6dbd3f6b0b1c45 completed CI/Supply Chain GREEN. Fresh CodeRabbit review then found the request-target case-folding false-GREEN plus exact completion-message and Markdown accuracy defects. Test/documentation repairs 369528831929ceae4b6892188f0d28e27b447592, 0c2cfce661c4b2d9b40407842fa5d6ee8df5cc8d, and 7c8f27222152a62b21d0b19a303cd2b0c5cebd08 fixed those without changing production Rust, routing, observability vocabulary, traffic volume, auth/TLS, timeout, or product authority. Hosted CI then exposed one formatter-only RED; 5b58bcf982f286495d5beda19fa3da902e6378a4 applies exactly the Rust 1.98.0 layout.

Fresh CodeRabbit review covers exact current range 3db4fe08e3c2145559ea01b01598a028d0be798b..5b58bcf982f286495d5beda19fa3da902e6378a4, explicitly revalidates the case-sensitive request target, exact field identity, concurrent listeners, finite origin bounds, exact Prometheus sample, exact completion message, full-stderr sentinel exclusion and implementation/doc consistency, and reports no new actionable finding. This is technical bot evidence, not independent human APPROVED governance.

Exact current hosted closure

Exact current head 5b58bcf982f286495d5beda19fa3da902e6378a4 is terminal hosted GREEN without predecessor transfer:

  • CI 34215770590: oci-runtime 102027034343, load-contract 102027034598, and test 102027034900 all completed success. The test lane passed exact checkout, Rust 1.98.0 formatting, compile/test, strict lint, warning-denied public rustdoc, complete owned-production coverage enforcement, and resolved dependency-lock verification. OCI passed both admitted non-root/read-only least-privilege profiles; routed/generic load evidence completed successfully.
  • Supply Chain 34215770673 / candidate-evidence 102027107538: committed dependency audit, both candidate-image builds, SPDX SBOM, both image scans, exact-source binding and evidence upload all completed success.

#23 is therefore stable enough to serve as the exact parent for ordinary/non-force #24 succession. #24 has now adopted this unchanged final head and must independently acquire its own exact hosted/current-range review evidence; no #23 receipt transfers.

Supplier #54/#62 and #56 independent approval remain earlier promotion gates. Keep Draft. No self-approval, force-push/destructive rebase, gate weakening, protected merge, immutable release, shadow/canary, cutover, rollback or legacy-removal credit is authorized.

Merge Risk: 🔵 Low · up to 36952

This change adds integration coverage for payload-free gateway observability and documents the contract. It is low risk to merge, but the completion-log assertion should enforce the exact message and the Markdown heading issues should be corrected so the documented contract and checks remain precise.

[P1] Preserve request-target bytes in the origin assertion

At Lines 243-246, request.to_ascii_lowercase() also lowercases the URI/query before the test compares it. HTTP field names are case-insensitive, but the request-target is case-sensitive. Therefore, a gateway that changes /api/log-contract?customer=query-secret to /API/LOG-CONTRACT?CUSTOMER=QUERY-SECRET before forwarding can pass this fixture. The test then does not prove that the backend received the supplied URI/query sentinel.

Parse the request line separately and compare its method, request-target, and HTTP version without case normalization. Keep case-insensitive matching only for field names.

In particular, verify that the latest commit is only the hosted Rust 1.98.0 rustfmt repair and that the payload-free observability contract, full-stderr sentinel exclusion, exact header-field/Prometheus oracles, finite origin read bounds, and parent-first four-path scope remain intact.

Commit 89aa2940ad8f6705610f050f9a6dbd3f6b0b1c45 changes only tests/pg_erd_payload_free_observability.rs. Its diff is Rustfmt-only line wrapping. The four-path child scope remains intact. The finite origin read bounds, exact header-field oracle, exact Prometheus sample oracle, concurrent listener reservations, completion synchronization, and full-stderr sentinel exclusion remain present.

[P1] Compare the request-target without case normalization

In tests/pg_erd_payload_free_observability.rs, the backend assertion calls request.to_ascii_lowercase() before it compares the request line. This normalizes the URI and query string. HTTP field names are case-insensitive, but the request-target is case-sensitive.

A forwarding regression that changes:

/api/log-contract?customer=query-secret

to:

/API/LOG-CONTRACT?CUSTOMER=QUERY-SECRET

can pass this fixture.

Parse the request line separately. Compare the method and HTTP version as appropriate. Compare the request-target to the expected bytes without normalization. Keep case-insensitive matching only for HTTP field names.

The effective child delta has four paths. Commit 89aa2940ad8f6705610f050f9a6dbd3f6b0b1c45 is Rustfmt-only. CI 34210071088 and Supply Chain 34210071098 are terminal GREEN for this exact head.

The fixture retains concurrent listener reservations, finite origin read bounds, exact HTTP field-name matching, exact Prometheus sample-line matching, and full-stderr sentinel exclusion. The documentation matches those implemented checks.

[P1] Preserve the request-target when you validate the backend request

At tests/pg_erd_payload_free_observability.rs Line 244, request.to_ascii_lowercase() normalizes the complete request line. This includes the request-target and query string. HTTP field names are case-insensitive. The request-target is case-sensitive.

A forwarding defect that changes:

/api/log-contract?customer=query-secret

to:

/API/LOG-CONTRACT?CUSTOMER=QUERY-SECRET

can pass this test. The test therefore does not prove the documented exact URI/query sentinel contract.

Parse the request line before header parsing. Compare the request-target bytes directly to the expected value. Apply case-insensitive comparison only to HTTP field names.

Fresh owner technical review of exact range 3db4fe08e3c2145559ea01b01598a028d0be798b..89aa2940ad8f6705610f050f9a6dbd3f6b0b1c45 after terminal hosted execution. Re-read all four effective paths and the resolved inline thread. The current test waits for the completion log while the child is alive, inspects complete captured stderr for every sentinel, uses finite origin-header bounds, exact HTTP field matching, and exact Prometheus sample matching. CHANGELOG/Test Strategy/baseline preserve the observability ownership boundary and do not transfer predecessor execution. No still-valid actionable finding found on this exact range. This COMMENT is technical review evidence only; it is not self-approval or the independent human APPROVED governance required for protected promotion.

@seonghobae Review completed for exact range 3db4fe08e3c2145559ea01b01598a028d0be798b..369528831929ceae4b6892188f0d28e27b447592.

I reviewed the current four-path child delta. I did not transfer review credit or hosted receipts from 89aa2940....

The P1 repair is correct. tests/pg_erd_payload_free_observability.rs now compares the complete origin request line directly:

GET /api/log-contract?customer=query-secret HTTP/1.1

This preserves the case-sensitive request-target and query. header_values() applies case-insensitive matching only to exact HTTP field names. Therefore, Host remains case-insensitive, while a modified URI or query cannot pass the fixture.

The fixture still includes finite origin read bounds, exact header-field matching, exact Prometheus sample-line matching, concurrent listener reservation, and full-stderr sentinel exclusion. The three documentation paths describe the same contract.

I found no new actionable findings in the reviewed range. This technical review is not independent human approval.

Verified P1 repair: 369528831929ceae4b6892188f0d28e27b447592 removes whole-request-line ASCII lowercasing. The origin request line is now split before header parsing and required to equal exact GET /api/log-contract?customer=query-secret HTTP/1.1; case-insensitive comparison remains limited to HTTP field names. This is test-only and leaves production routing/observability behavior unchanged. Predecessor 89aa2940... GREEN/review evidence is not transferred; exact CI 34213659178 and Supply Chain 34213659147 are running for the repaired head.

@seonghobae Review completed for exact range 3db4fe08e3c2145559ea01b01598a028d0be798b..7c8f27222152a62b21d0b19a303cd2b0c5cebd08.

I reviewed the current four-path delta. I did not transfer predecessor review credit.

The request-target repair is correct. The fixture now compares the complete origin request line directly at tests/pg_erd_payload_free_observability.rs Line 248. URI and query casing remain case-sensitive. header_values() limits ASCII case-insensitive comparison to complete HTTP field names.

The latest head also strengthens the completion-log oracle. At Lines 324-331, the fixture extracts the message after gateway_request and requires exact equality with:

status=200 outcome=ok request_body_bytes=0

This prevents extra completion fields from passing a substring check.

The fixture retains concurrent listener reservation, five-second origin read bounds, a 64 KiB origin-header cap, exact Prometheus sample matching, non-vacuous backend sentinel checks, and sentinel exclusion across complete captured stderr. src/observability.rs matches the asserted completion vocabulary and request counter. The documentation is consistent with the implementation.

I found no new actionable findings in this exact range.

PR #23 is still Draft. The current CI and Supply Chain jobs for this head are queued. They are not completed hosted evidence. This technical review is not independent human approval.

I did not transfer predecessor review credit.

Commit 5b58bcf982f286495d5beda19fa3da902e6378a4 is a formatting-only change. It changes only the Rustfmt layout of the exact completion assert_eq! in tests/pg_erd_payload_free_observability.rs.

The current fixture preserves the required semantics:

  • It compares the complete origin request line directly. URI and query matching remain case-sensitive.
  • It matches complete HTTP field names case-insensitively. X-Forwarded-Host cannot satisfy Host.
  • It retains concurrent traffic and metrics listener reservations.
  • It bounds origin header reads to five seconds and 64 KiB.
  • It requires the exact Prometheus sample line cwl_pingora_gateway_requests_total 1.
  • It requires one exact completion message: status=200 outcome=ok request_body_bytes=0.
  • It excludes all request-sensitive sentinels from captured stderr.
  • src/observability.rs emits the completion vocabulary and counter that the fixture asserts.
  • The three updated documentation paths remain consistent with the implementation.

I found no new actionable findings in this exact range.

PR #23 remains Draft. The CI and Supply Chain checks for this exact head are queued. They are not completed hosted evidence. This technical review is not independent human approval.
