Why

A confident same verdict could automatically merge entities whose names a statements source declared to be identities. This implements ADR 0071 decision 7 using the existing {"names":"identity"} source flag.

Closes #1248

What changes

• Both adjudication paths use one merge gate that checks current name evidence on either entity, including aliases and mixed prose/identity evidence. A held merge leaves both entities live and records escalate_identity for human review.
• Batch, cached, and second-look verdicts use the gate. Governance retains the model's verdict as a proposal with the hold reason. Confident kept verdicts still close automatically, and people can still merge entities themselves.
• Add the review reason in English and Chinese, and mark ADR 0071 and its index entry implemented.

How it was checked

Checked commit 2916e332150bc5baa1435c0a0fd14721bf85f899 on Linux x86_64 with Rust 1.99.1, PostgreSQL 16.15, pgvector 0.6.0, and Poppler with CJK data. The test database was created with UTF-8 encoding and all migrations applied.

• cargo test --workspace: 1,709 passed, 0 failed, 6 ignored, with UTOPIA_TEST_REQUIRE_DB=1 and UTOPIA_TEST_REQUIRE_PDFTOTEXT=1. The six ignored tests are existing live-service and isolated delivery experiments.
• cargo clippy --workspace --all-targets -- -D warnings: passed.
• cargo fmt --all --check: passed.
• Frozen pnpm install, pnpm build --outDir /var/tmp/utopia-1248/web-dist, and pnpm test: passed; 326 web tests across 47 files.

The three new database-backed regressions use mocked confident model verdicts to cover governance on/off, direct batch and second-look decisions, aliases with mixed evidence, cached verdict replay after a source flag change, kept decisions, and sources without the identity flag.

Before review

• Every commit is signed off.
• Rust formatting, Clippy, and the full workspace tests pass.
• Web build and tests pass; UI strings are in both languages.
• The SQL change was exercised against PostgreSQL with database tests required.
• ADR 0071's status line and index are updated.

Thanks @Aschenbath, this does what 0071 decision 7 says, and only that. One gate, hold_for_merge, covers the batch, cached and second-look verdicts and the governor. Either side counts, current name evidence including aliases and mixed prose evidence counts, kept still closes, and a person's decision is unchanged. The tests cover governance on and off and both verdicts. Two small things before merge:

1. The three comments in adjudication_identity_tests.rs should be in Chinese, per the repo convention.
2. ADR 0071's status line should name the PRs: Implemented · 2026-10-25 · #1333, #1390, #1425 · open: none.

Optional: reuse name_vectors::has_identity_evidence! instead of a second copy of the join, and let the governor's consequences tool mention the identity hold. Separately, merge_entities drops fact_evidence when it deduplicates name facts, so a person's merge can take identity status away from the survivor; that's #1426, not this PR's job.

[Aschenbath]

Thanks. Both requested changes are in 94b180e: the three comments in adjudication_identity_tests.rs are now in Chinese, and the 0071 status line reads Implemented · 2026-10-25 · #1333, #1390, #1425 · open: none. I kept this push to those two items. Reusing has_identity_evidence! and mentioning the identity hold in the governor's consequences tool both change code, so I'd rather send them as a separate small follow-up than widen this PR after review. Noted on #1426.

[WaylandYang]

Thanks, both changes are in. The optional reuse and the governor wording are fine as a follow-up. Merging.
