Adds a second machine class (small fan-shaped reach arm) alongside the
CR-10/AxiDraw rectangular-bed plotters, so wet signatures can be produced
while away from the home station.
ink_signature_plotter.py:
- PlotterConfig gains dialect (marlin|lineus) + name; new LineUsConfig
(native units, pen height = per-move Z, reach annulus from shoulder pivot).
- Named machine profiles (cr10 default, axidraw, lineus) via load_profile().
- bed_mm_to_lineus_units(), check_reach() (annulus for lineus, rectangle for
marlin), compute_jig_offset_for_box() (solves jig from the ACTUAL fitted ink
extent so a wide cell line doesn't over-constrain a small arm).
- emit_gcode() dispatches to emit_marlin_gcode()/emit_lineus_gcode().
- send_lineus(): WiFi TCP 1337 (NUL-terminated, ok-acked) or USB serial,
dry_run=True default (same gating as the CR-10 path).
ink_signature_cli.py: --profile, --solve-jig (auto-applies jig offset),
--lineus-host/--lineus-usb, reach-check that refuses to --plot out-of-reach
on Line-us.
Tests: 43 checks (was 30) covering profiles, reach check, jig solve, lineus
emitter, dry-run sender. Docs updated with profiles + portable workflow.
The Standard no-login CMS path needs an ORIGINAL ink signature on paper
(CMS-10114: 'Stamped, faxed or copied signatures will not be accepted'). This
adds a pipeline to redraw the provider's own captured strokes in real ink with a
pen on a CR-10 V2 (or any Marlin/GRBL machine) — original, in ink, never copied.
- migration 090: esign_records.signature_vector (JSONB stroke paths, 0..1).
- signing page now captures normalized stroke paths alongside the PNG; API
stores a size-bounded vector for drawn signatures.
- ink_signature_plotter.py (hardware-independent): fit strokes to the signature
anchor box, PDF-pt -> bed-mm via jig offset, emit Marlin/GRBL G-code (Z pen or
M280 servo/BLTouch), SVG toolpath preview, and render_signature_on_pdf (a
digital twin that proves the toolpath lands on the cert line). Gated serial
sender (dry_run default).
- ink_signature_cli.py: end-to-end load-record -> gcode+preview, --test-box jig
calibration, --plot to stream over USB.
- Corrected CMS-10114 signature anchor to sit inside the Section 4A signing cell
(above the bottom rule, below the label).
- docs/ink-signature-plotter.md documents the CR-10 retrofit + interpretive risk.
Tests: test_ink_signature.py 30/30, test_cms10114.py 27/27, test_paper_batch.py
15/15, API tsc clean, Astro build 58 pages.
