feat(modes): the kernel modes - a patch series and a mailing-list reply

Beside the push gates, crafter-review runs the pre-send review of a kernel
contributor's workbench: --mode series over a format-patch export with its
cover letter, --mode reply over a mail draft. The inventory partitions a
cover letter, a plain mail and the camera review's shape; ten kernel lenses
join the table with their gates (structure, code, artifact truth) and the
persona gate - one maintainer-persona instance per --reviewers entry, its
whole pass gating its blocks and pruning the units that are not theirs. A
series' code units are keyed on the code like the push gates'; every text
unit on its text, the references it cites and the anchor when it is dated.
The references an artifact cites are prefetched through utilities/lore.py
into the gate-state, with a digest in the run layer, and a persona's
calibration map is its lore listing. The kernel schema carries the persona
vocabulary, the kernel note kinds, the predicted review and the not-mine
list; the matrix the persona holes, the thin and the modelled units; gates
clean without a persona pass is GATES CLEAN. A reply's gate-state sits
beside the draft and is read once; a kernel mode needs --subsystem,
defaults the effort to max and the trees to work/linux,work/milos-linux,
and excuses no unit from the holes.

The kernel lenses and the common text ship verbatim; the table lists them
after the push gates' lenses and the config template holds them off, so a
repository that never turns them on changes nothing. Prompts, keys and plans
were checked byte for byte against the pipeline these modes replace, on its
own artifacts: two replies and a series, every system prompt, user prompt,
job and reuse key identical.

+Hallo Thomas,
+
+Dank je voor de nieuwe versie.

+De eerste patch ziet er goed uit; zie punt 1 hieronder.

+ov13b10-of/0000-cover-letter.patch
+
+De cover noemt de test op 2026-09-10; dat klopt met wat ik zag.
+
+Dates: every "still", "unmerged", "in review" and "latest version" below is
+as of 2026-09-21 (work/linux at v7.1-rc2, work/milos-linux at v7.1.2-milos).
+
+Reversals of the 2026-08-18 review (two points where that review was wrong):
+
+R1. The active-array origin (ov13b10 3/3). The 08-18 review said the origin
+was (0, 0); the datasheet [1] gives (8, 8), so the earlier ask is withdrawn.
+
+R2. The link-frequencies constraint (ov13b10 1/3) depends on R1 and on the
+binding example in [2]; it is still open as of 2026-09-21.
+
+camss-milos
+
+1. num_clients (camss 2/5). The field is read once; the v3 series on the
+   list [1] does the same.
+  a. The error path leaves the clock enabled.
+  b. The comment above it names the wrong register.
+
+2. Required supplies (camss 1/5). Matches the binding in [2].

+This series adds the widget driver and documents its binding.

+The driver was tested on the board described in [1]; the binding follows

+The widget answers on I2C and reports its revision at probe. The probe
+reads the revision register once and keeps it for the sysfs attribute.
+
+Tested on the board as of 2026-09-20 with v1 of the firmware.
