+# Topics Table Layout — Architect Review
+
+**By architect.**
+
+## Task and commits reviewed
+
+- Task: `topics-table-layout` (refactorer handoff
+  `merge_and_process refactorer ec753a9c88`).
+- Merged `swarmforge-refactorer` (fast-forward). Commits:
+  - `41af8f9` Spec topics table layout
+  - `ac4d9ea` Render topics page as a table (coder)
+  - `ec753a9` Add property tests for the topics table view model (refactorer)
+- Architect review commit: `d1f0f76` (tool-written mutation manifests only).
+- Verification record `git_sha`: `d1f0f76cca`.
+- Records/summary commit: (this commit).
+
+The feature replaces the topics page flexbox list with a react-bootstrap
+`Table` so the four columns line up, driven by a pure `buildTopicsTable` view
+model (headers, per-row cells, feed link, horizontal-scroll wrapper). Client
+only.
+
+## Architectural findings
+
+- **UI/Core separation (good).** `src/services/topics-table.js` is a pure view
+  model with no DOM or React dependency, so the header order, per-row cell
+  order, link encoding, and scroll wrapper are all testable without a DOM. The
+  React `Topics` component is a thin shell that maps the model into
+  `<Table>`/`<thead>`/`<tbody>`; it is the environmentally unsuitable boundary
+  and stays excluded from language mutation, consistent with the established UI
+  precedent.
+- **Dependency direction (good).** The view model reuses `relative-time.js`
+  for the label and `TopicDiscoveryPage.topicFeedPath` for the row link, so the
+  path encoder is not re-implemented. `TopicDiscoveryPage` remains the
+  load/pagination controller and the component's only data dependency.
+- **Information hiding (good).** The component consumes only `headers`,
+  `rows[].cells`, `rows[].href`, `rows[].room`, and `wrapperClass`; the model
+  hides the column order and percent-encoding. The horizontal-scroll contract
+  is represented as `wrapperClass = 'table-responsive'` rather than left to
+  JSX inspection.
+- **Local quality (good).** `buildTopicsTable` scans at CC 1 / CRAP 1.0 with
+  100% coverage. `?? 0` defaults and `relativeTime` cover omitted count and
+  last-seen fields for legacy topics.
+- **Observation, not changed.** The component recomputes the feed path in
+  `handleClick` while each row already carries `href`; both produce the
+  identical encoded path, so the redundancy is harmless.
+
+## Fixes applied
+
+None required. Language mutation killed every site, `dry4javascript` reported no
+candidates, CRAP is 1.0 at 100% coverage, and soft Gherkin mutation killed every
+mutation. The architect commit contains only the tool-written
+`mutate4javascript` manifest and the `gherkin-mutator` stamp/manifest.
+
+## Verification
+
+Record:
+
+| File | Component |
+|------|-----------|
+| `docs/reviews/topics-table-layout-verification.json` | psf-memo-client |
+
+Suite status (all `pass`): **psf-memo-client** 447 unit, 94 property,
+34 acceptance suites, lint ok, build ok.
+
+- **Language mutation** (`mutate4javascript`, `--max-workers 8`):
+  `topics-table.js` 2/2 killed, 0 survived.
+- **DRY** (`dry4javascript`, scoped to the changed service, component, unit and
+  property tests): no candidates.
+- **CRAP** (`crap4javascript`): `buildTopicsTable` CC 1 / CRAP 1.0 / 100%
+  coverage.
+- **Soft Gherkin acceptance mutation** (`gherkin-mutator --level soft
+  --workers 8`): `topics-table-layout.feature` 16 total, **16 killed**, 0
+  survived → the tool wrote a `# mutation-stamp` plus the per-scenario manifest
+  (committed as-is).
+
+## Handoffs
+
+- End-of-chain `git_handoff` to `specifier` (priority 50) to merge
+  `swarmforge-architect` into `master`, using the records/summary commit.
+- No coder/refactorer follow-up: the commit is tool-written mutation metadata
+  only, with no production or test change.
