Summary

Scoring now owns confirmed Bug-origin reads and shares ordered checkpoint storage with full sample reads. Metrics joins the resulting PR URLs and optional exact local Ticket run identities to its captured Commands.

Run metrics → Scoring confirmed origins → shared ordered checkpoint reader
            → retained pull-request attribution → captured Commands

Closes #1313

Test seams

• Scoring's confirmed-origin read operation over private temporary checkpoint storage.
• Existing metrics CLI and CLI/Console Command-details interfaces for retained attribution and late decisions.
• Existing Scoring retained-file commit and publication interfaces.

Evidence

• Before: metrics separately discovered, decoded and ordered Scoring checkpoints. The new confirmed-origin test failed at the unimplemented operation; the supersession test then failed with four confirmations instead of two before reduction was added.
  After: cargo test --bin thirdshift scoring::store passes all 11 tests, including seven tests through the confirmed-origin operation and the four existing storage regressions.
• cargo test --test metrics bug_origin: 6 passed; covers Continuations, dispatched names, correction/rejection, weekly accounting and unchanged Command records.
• cargo test --test console metrics::: 3 passed; CLI/Console details refresh from minimal retained records through proposed, confirmed, rejected and unknown states.
• cargo check --bin thirdshift, cargo fmt --check, and cargo clippy --all-targets -- -D warnings: passed.
• First /usr/bin/time -p scripts/affected-tests main: failed after 728 passed because otlp_endpoint::a_stalled_receiver_cannot_delay_a_session_by_its_span_count exceeded its baseline-plus-two-seconds timing bound (3.93s baseline; 7.65s stalled). Wall time 1067.99s, including compilation and an initial build-lock wait; 2,282 tests were not reached.
• That exact OTLP test subsequently passed both cargo test --test otlp_endpoint a_stalled_receiver_cannot_delay_a_session_by_its_span_count -- --exact --nocapture and cargo nextest run --test otlp_endpoint -E 'test(=a_stalled_receiver_cannot_delay_a_session_by_its_span_count)' in isolation.
• Final validation: CI run 40191701060 passed for the exact reviewed head cc392243: the full Linux Rust suite, macOS gate, Console browser tests and site checks. Release builds and smoke checks also passed. Reused that successful full-suite evidence as docs/testing.md directs, and stopped the redundant two-worker local rerun after 508 passing tests; its remaining tests were interrupted deliberately.

Merge Danger

Door: two-way

Blast Radius: metrics

The shared reader serves retained sample writers and the read-time counts in metrics, show --json and Console Command details.

Standards

Spec

None. Independent review found 0 findings.

Security

None. Guidance-mode security review of the issue-1313 diff against merge base bd4b3e72 found 0 introduced findings. The change moves confirmed Bug-origin reads into Scoring behind one read-only operation over shared ordered checkpoint storage; metrics keeps its existing retained pull-request attribution join. Verified: no new file, network, process or lock sinks in the changed modules (only pre-existing writer paths remain), stored local record paths are compared lexically and never opened, stable chronological ordering and issue normalization are byte-identical to the removed metrics reader, and malformed data still fails visibly. cargo test --bin thirdshift scoring::store (11 passed) and cargo test --test metrics bug_origin (6 passed) confirm preserved behavior.

Security review outcome

No unaddressed introduced findings.

Review coverage

Both independent reviewers inspected all seven changed files against main pinned at cff9109e6ba567ee720c823fc4598e283a0d94e2 (merge-base bd4b3e72460f16f33cc365798fe9cca1f0b409b5). No changed files were left unread by either axis; no generated-output exclusions. Reports and each axis's final supporting-file list are saved alongside the Session trace as .thirdshift-review-6OztlO/standards.md and .thirdshift-review-6OztlO/spec.md.

Standards: 0 findings; Spec: 0 findings; no worst issue on either axis.
