## Row 70 round 2 review (Filbert): approve

Candidate: manifest sha256 `098b9aefe830c53173f0b673705e2fddfa5b49a9ba23903a045bf72d8875604e` (4 paths), base 48b893871, packet agents/sage/work/queue-70/r2/ in 4a34fb0d6.

Rebuild: a fresh worktree at 4a34fb0d6 (current refactor) with the r2 build.patch applied. Every manifest hash matched, `git diff --check` was clean and `bash -n scripts/mosaic` passes. The added lines have no dash, curly-quote or control characters. The packet manifest checks. No commit from 48b893871 to 4a34fb0d6 touches a manifest path.

I rebuilt round 1 on my own `git archive` of 48b893871 and diffed it against round 2. The changed lines match delta.patch exactly.

### Round 1 findings (28598)

| Finding | Status | How I checked |
|---|---|---|
| F1 scripts/mosaic header omits `mosaic-old` | Fixed | The header now says "On Jason's host the estate CLI it replaced is `mosaic-old`." Every `+` and `-` line in scripts/mosaic against the base starts with `# `, so no code line moved. |
| Doc-only 1, TOOLS.md | Fixed | It names `mosaic-old` and links `../packages/cli/README.md#one-pinned-copy-row-85-1579`. The path resolves from docs/, and the anchor matches the heading at packages/cli/README.md:466. |
| Doc-only 2, seat README | Fixed | It links `../../docs/TOOLS.md#stack-copies-scriptsstack-copysh`. The path resolves from packages/seat/, and the anchor matches TOOLS.md:276. |
| Test comment note | Fixed | It now says lines that start with `# ` are left out, and that the shebang and other lines stay in. The filter code is unchanged. |

### What I ran

As a single file with TMPDIR set and Docker disabled: queue dispatch, 4/4.

These mutants ran on round 2's scripts/mosaic:
- Dropping `REPO=`, `set -euo pipefail`, the shebang or the seat `exec` each fail "the pre-A2 fixture is the script A2 changed" and name the missing line.
- Commenting out the set line as `# set -euo pipefail` also fails.
- Dropping the new `mosaic-old` header line passes, as intended.

I restored the file and rechecked the manifest afterwards.

**From Sage's receipts, not rerun by me:** the round 1 gate (24 suites, 0 failed). Round 2 changes comments and Markdown only, and the landing gate reruns everything on HEAD.

I took no slot.
