Priority: ⬇️ Low Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The new relation-verification gate can overstate corroboration when a forwarded source quotes a different span of the original evidence, and malformed timestamps can fail processing after model work has occurred. It remains non-writing and leaves truth unverified, so impact is bounded, but these cases should be addressed before relying on its classifications. Sequence Diagram(s)sequenceDiagram

- Line 14: Promote the former _validated helper to the public
validate_extracted_relations name in relation_backfill.py, preserving its
validation behavior, and update relation_verification.py to import and call the
public validator. Keep _validated as a thin compatibility alias for existing
internal callers, and ensure the single-proposal validation error no longer
describes the batch as retryable.
- Around line 190-198: Update the independent-support guard in the relation
verification logic to reject references whose judgment quote appears verbatim
within primary.content, while preserving the existing origin, chunk, content,
and relation-quote checks and leaving the model repeats verdict as the semantic
control.
- Around line 71-76: Update _date and the created_at handling in _check_window
to reject non-string values such as datetime and bytes before parsing, and catch
TypeError alongside the existing parsing errors. Preserve valid ISO string
parsing and ensure invalid created_at values return the existing rejection
outcome without raising after the model response is recorded.
In `@tests/test_relation_verification.py`:
- Around line 114-125: Add a parametrized chronology case in
test_chronology_distinguishes_correction_expiry_and_prior_denial using a
timezone-naive timestamp, and assert it produces UNKNOWN while preserving the
existing verdict and status coverage.

@codex review Second review request at b18c0b7. All first-round correctness findings are fixed and replied to; the private-validator API rename is explicitly deferred. Includes the reviewed Bun dependency from #816 unchanged. Guarded pre-push passes with BRAINLAYER_FORBID_EMBEDDING_MODEL=1; 93 focused Python tests pass. Please assess the current head. Original frozen extraction FAIL and canonical-write prohibition remain unchanged. — astra-brainlayer (worker) · codex/gpt-6-astra |

A verbatim quote and valid entity IDs can still describe a negation, a question or a policy rather than the proposed runtime dependency. Add a separate source-assertion and corpus-review library that checks the original proposal against supplied evidence, preserves raw reviewer output and ordered evidence before parsing, and distinguishes corroboration, rejection, uncertainty, historical endings and an unbound policy target.
The library requires recognized non-hidden source classes, shares memory-reader exclusions with ingestion, snapshots mutable review inputs, rejects malformed origins and timestamps, and refuses quote repair for both support and policy outcomes. Independent support must have traceable origins and cannot quote a span copied from the primary source. Raw text and UTF-8 bytes produce the same parsed review and hash, with original bytes retained before decoding. Every outcome leaves current graph truth unverified and canonical writes unauthorized. There is no runner integration, retrieval, scheduling or database writer in this slice.
Nobody loosens that gate. The original frozen extraction FAIL stands. Requalification must be a new frozen round with exposed-set disclosure, separate raw/accepted denominators, and candidate/retrieval recall reported independently. This slice does not qualify a model or establish end-to-end graph readiness.
Validation at a00874b: 102 focused pytest cases pass (66 verifier, 25 existing backfill, 11 provenance), Ruff lint/format pass, and the scoped pre-push gate passes with BRAINLAYER_FORBID_EMBEDDING_MODEL=1. The Bun fixture completes its FTS assertion without loading an embedding model. Correctness fixes were reproduced with failing regressions before implementation. The Claude pair independently ran 91 verifier/backfill tests and approved the final byte-response delta; adding 11 provenance tests reconciles the 102 total. Main dependency #816 has landed. Final branch head 10ce4a4 incorporates that main merge with an identical git tree to reviewed a00874b; its guarded pre-push also passed. Latest-head CI remains pending; do not merge until it passes.
Dependency #816 merged first at 105dd47, retaining reviewed fd1df7b as an ancestor. Its test file has dropped from this PR: the final diff is only the three verifier files, +575 lines. The existing marked Python embedding-baseline test remains intact.
Carried limits:
Size L rationale: one cohesive verifier contract with its negative-path tests and public limits, three files / 575 added lines. The Claude pair approved through a00874b, including independent execution of 91 verifier/backfill tests. Two explicit Codex rounds are complete: first-round correctness findings and the second-round blank-origin finding are fixed. Macroscope's subsequent byte-response finding is fixed in a00874b, and its review of that delta reports no issues; its timestamp documentation suggestion is explicitly declined because it would conflate observation dates with effective dates. The public-validator API rename is deferred to runner integration. CodeRabbit's actual first review was addressed; its latest status is review-rate-limited, not a clean latest-head review. DeepSource skipped and Bugbot quota-limited; neither is counted as a clean review. Bugbot and Greptile are not mandatory reviewers.
