 **What this does not fix, and should be the next pass:** the iso room occupies roughly a third of the phone's height with dead space above and below — the screen-composition complaint (§11) and the mobile pass (§12) he named are still open, along with §7 (leather-buying interface), §9 (HUD restraint) and §13 (coherence sweep). No issue/PR/release surface for this build exists (no `leathermint` repo on the forge); the receipt is this ledger plus the served paths. No secret printed.

+**gate_blame 2026-10-20 19:40Z (volt, Workhorse) — a gate red is now attributed to the landing that turned it, and the live check-in red is measured to `a013842`.** No item opened or closed; the open set is unchanged (`Q37:5278` pipe, career-lane `Q53:7303` held for Alexander). Appended at the foot with the index re-rendered in the same commit.
+
+1. **The gap this fills, stated as an absence rather than a wish.** `verify.py` grades five legs of ONE tree, so every "is this red mine?" costs a manual parent checkout. On 2026-10-20 three replies in a row — `replies/2026-10-20-to-volt-42.md`, `-43.md`, `-44.md` — each re-proved the same inherited check-in fault by hand, in prose, and each said so in its own words. Three reproductions of one fact is an instrument missing, not diligence.
+2. **What landed.** `tools/gate_blame.py` walks the last N first-parent commits, materialises each as its own detached worktree, and grades it with `verify.py`'s own `run_leg`, so a revision is graded by ITS tool file and ITS `checkin_baseline.tsv` — the tolerance it committed, not this host's idea of one. It reports the OLDEST commit whose verdict differs from its parent; a detail change at a constant verdict prints `CHANGED` and is deliberately never called a flip.
+3. **The measurement, on the live fault.** `--leg checkin --ref a013842 --range 4` → **rc 1, FLIP at `a013842` (2026-10-19 23:44:47Z, PASS → FAULT)**, with one `CHANGED` at `7046673` (PASS → PASS, 76 → 77 files) — the "detail change is not a flip" rule demonstrated on the record rather than on a fixture. `--range 12` at HEAD → **rc 0, 0 flips, FAULT at all twelve commits**: the red is inherited across the entire window, which is the machine-checkable form of what replies 43 and 44 argued in prose. The fault itself remains zephyrus's to close — two files for 2026-10-19, `checkins/2026-10-19-zephyrus.md` and `checkins/2026-10-19-zephyrus-sovereignty.md` — because this lane does not rename another wizard's record to turn its own report green, which is `checkin_check.py`'s stated policy.
+4. **Integration, and a defect the repo's own oracle caught in my first commit.** Both sweep axes carry a row (read-refusal rc 2; malformed-input rc 2 naming "not a git work tree"), and `selftest_sweep.py` now reads **18 tools, 18 OK, 0 fatal** (was 17). Landing `2c2184c` imported `verify.py` at module level; `tool_map.py` renders a tool's `--help` oracle from a lone temporary copy of the file, so the map printed `no --help oracle` for a tool whose own `--help` worked in-tree. Fixed in `ad20c75` by deferring the import to `gate()`, with the lone-copy case added as a selftest cell (20 → 21 cells); `docs/TOOLS.md` re-rendered at `64c9792`, `--check` rc 0.
+5. **Two readerless counts retired while I was in the file.** `selftest_sweep.py`'s own prose said "eleven tools must refuse at rc 2" and "Fourteen tools" — both already stale, and both words, so no gate could see them: the exact defect class that file's docstring names. Replaced with count-free wording plus a note saying why the count is not written there.

+Verification at this commit: `gate_blame.py --selftest` **21/21 rc 0**; `selftest_sweep.py --repo .` **18 tools, 18 OK, 0 fatal, rc 0**; `doc_command_check.py --repo .` **54 commands over 16 oracles, OK 54, rc 0**; `tool_map.py --check docs/TOOLS.md` **rc 0**. Full `verify.py` reads the check-in leg RED throughout, as it did before this landing and for the reason named in item 3.
