feat: add CLI falsifiers and exit tables to the remaining twelve examples

[TMHSDigital]

Summary

Closes the example-falsifier retrofit on both axes: 55/55 flags and 55/55 README exit tables. Two commits: B1 behavior, B2 docs-only.

Issue #138's checker is still out of scope. This PR is what makes it buildable as an enforcing gate.

Part A already landed (context, not this PR)

#143 squash-merged as 89ae4eb (feat: add CLI falsifiers and exit tables to thirteen rigging examples). Release cut v0.60.0. Pages deployed. Smoke did not re-run on push (intentional). #131 and #138 remain OPEN.

B1 — final 12 falsifiers

Same treatment as batches 1–3: a flag that changes the input so an existing assertion fails. No assertion skipped, disabled, or bypassed. No exit-code value changed. Grease Pencil version shims were left alone; both GP flags are version-independent RNA (use_contour, cyclic). --check-pixels on vse-cut-list stays a second witness; the falsifier beside it is --swap-inputs.

Live-run-proven on local binaries (default must be 0; falsifier must be the documented code on all three). Falsifier was never 0.

Binaries: .scratch/blender-4.5.11-windows-x64/blender.exe, .scratch/blender-5.1.2-windows-x64/blender.exe, .scratch/blender-5.2.1-windows-x64/blender.exe. 5.1 evidence here is local; CI 5.1 is the labeled job.

Falsifiers are not on the default smoke path. No catalog.json edits.

B2 — thirteen README exit tables (inspection-only)

No flags, no behavior, no code-value changes, no local Blender runs. Codes copied from each script as they are. export-preset-axis exiting 9 is correct.

Pathology / sidecar (no gallery, by design):

• exit-pre-sidecar — 0, 1, 2, 77 (bullet list converted to the numbered table)
• coincident-vert-weld — 0–4
• gn-bundle-roundtrip — 0–5, 77
• ngon-triangulate — 0–4
• unapplied-scale-gltf — 0–4

Existing flags, missing tables:

• cross-version-property-delete — 0–7, 10, 12
• export-preset-axis — 0–11 (including 9)
• gn-zone-iterate — 0–6, 10, 12
• lightmap-uv-channel — 0–11
• modular-kit-snap — 0–9, 11 (check_framing is called with a documented deviation, so 10 is not reachable)
• socket-attach-points — 0–11
• usd-export-evaluation-mode — 0–6, 10, 12
• vertex-color-ao — 0–11

Final counts (this branch, before opening)

Falsifier flags 55/55:

python .scratch/count_falsifiers.py
# WITH extra flags 55
# WITHOUT 0
# total dirs 55

README exit tables matching CONTRIBUTING “Exit codes” / bake-normal (## Exit codes + | Code | Meaning |) 55/55:

python .scratch/count_exit_tables.py
# WITH exit table 55 / 55
# WITHOUT 0

Test plan

• B1 default=0 and falsifier=documented code on 4.5.11, 5.1.2, 5.2.1 (live)
• GP falsifiers did not need a per-version flag (live)
• B2 tables inspection-only against the scripts (no Blender)
• CI 4.5 + 5.2 smoke on the PR
• CI 5.1 smoke via needs-5.1
• Do not merge from this session
