Record the post-merge verification for the Sources browse redesign

[BigSimmo]

Summary

• One append-only branch-review record for the post-merge verification of #2593 (Sources Topics/Publishers browse redesign), written by npm run ledger:append --scope prlanded. No canonical ledger table row is touched, and no other file changes.
• Give Sources' Topics and Publishers the chrome the Catalogue already has #2593 was merged with a merge commit while a second session was pushing 87b1d5e to the same branch, so it is exactly the auto-merge race prlanded exists to catch. The record states what was verified by content rather than by ancestry alone: all seven branch commits are ancestors of origin/main; the eight changed files are byte-identical between branch tip 87b1d5e and main; and git diff 87b1d5e 0f85b91 is empty, so the merge took the branch tree wholesale and orphaned nothing. The remote branch was deleted on merge, so no late commit can be stranded behind it.
• The record also carries the post-merge evidence and the honest gaps: 102 unit tests green on merged main under TZ=America/Los_Angeles, the pre-merge focused browser proof, and the explicit note that verify:ui and verify:pr-local were never run locally.

Verification

• npm run check:ledger-write-discipline — Ledger write discipline passed for 0f85b916d62d..HEAD. (self-test passed first). This is the gate that governs this change.

• npm run check:branch-review-ledger — Branch review ledger guard passed: 880 live table records + 1206 archived + 604 immutable (880 under the 2026-07-29 machine-readable contract), immutable review writes, six cells each, no conflict markers, mojibake, heading records, or duplicates.

• npm run ledger:append wrote the record; the file is the tool's own output, committed unedited.

• npm run verify:pr-local

• npm run verify:ui

Verification not run: verify:pr-local was not run. UI verification not run: the diff is a single generated Markdown record under docs/branch-review-records/, with no source, route, style or browser surface in it — classifyPullRequestFiles returns clinicalRisk: false, ui: false, ragRanking: false, migration: false, operationalRisk: false. The two ledger gates above are the checks that actually apply.

Notes

• Append-only by design: docs/branch-review-ledger.md and docs/outstanding-issues.md are serial-only, and a normal PR must not add rows to either. This adds one immutable record file and nothing else, which is the sanctioned route.
• Content of the record is a verification report, not a claim of new work. The code it describes is already on main as 0f85b91.

Note

Low Risk
Documentation-only append to immutable review records; no runtime, auth, or data-path changes.

Overview
Adds a single append-only immutable row under docs/branch-review-records/ (via ledger:append / prlanded) documenting post-merge verification for PR #2593 — no application code, routes, or canonical ledger table edits.

The record captures the merge-commit race check (branch tip 87b1d5e vs merged 0f85b91: empty tree diff, byte-identical changed files, remote branch deleted) and what was actually run: 102 related unit tests on main, focused Chromium UI specs and verify:cheap on the branch, with explicit gaps (verify:ui, verify:pr-local not run locally; three shallow-clone verify:cheap failures called out as base artefacts).
