Audit dev@2c947f4, DEV-2C947-03 (P2). Three rooms in the core plus one dragged
90 canvases out: the frame rejected the stray exactly as §4.1 promises, and
then a perfectly ordinary marker on the main plan came out 90.89x too big and
covered the house. `contentFrame` voted; `iconUnit` did not — it took
`boxOf(every room)`, so the distance to the stray the frame had just thrown
away lived on in the numerator of `iconCqw`.
`iconUnit` now takes `contentFrame(roomItems, { pad: 0 }).core`: the same
main-mass vote, over the same rooms it always used (rooms only is what keeps
the full card and the static card bit-identical), with no padding, because
this is a UNIT and not a viewport. Below MIN_VOTERS nothing is declared an
outlier, so every ordinary plan — and every genuinely wide one, where the
majority veto applies — keeps exactly the unit it had. `defaultPositions`
takes its declump distance from the same call, so the auto-placement spacing
follows without a second rule.
Unit (test/canvas.test.mjs): a far room leaves both the frame and the icon
unit alone, `iconCqw` on the strayed plan equals `iconCqw` on the same plan
without the stray, and a plan that is honestly two canvases wide still scales.
smoke_canvas_frame.mjs measures the rendered badge in px with and without the
far room. Both are red on the parent commit.
Two owner corrections after the infinite canvas.
- --icon-size goes back to being a percentage of the PLAN: a marker
grows and shrinks with the zoom, like everything else drawn on the
plan. The infinite canvas had made it a percentage of the viewport
(fixed pixel size) — the owner looked at it and asked for the
original contract back.
What survives from the canvas work is the NUMERATOR. The old
expression divided by `vb.w`, the stored view_box, which is not a
frame any more; a fixed NORM_W in its place would have shrunk every
marker on a plan drawn past the old square by exactly the factor the
plan is outsized (an invisible dot 50 canvases out). So it is now
`iconCqw() = iconPct * iconUnit(space) * kioskScale / view.w`, one
pure helper both renderers call. `iconUnit` is exactly NORM_W for
any plan that fits the old square — and the editor has never written
anything but `view_box: [0,0,1,1]` — so the rendered size is
bit-identical to the pre-canvas card: measured against the v1.56.0
bundle at a fixed view, both give 3.400 / 3.091 / 6.182 / 12.364 cqw
= 28.52 / 26.11 / 50.22 / 98.44 px. On a plan drawn at 1.5..3.8 the
marker is 26.1 px, the same as on an ordinary plan, instead of the
~11 px a fixed numerator would have given.
The static space-card uses the same helper: it has no zoom, but its
frame is the content now, so a bare iconPct shrank its markers as
the frame tightened. marker.size, the kiosk scales and every
satellite still ride on --dev-size, untouched.
- the icon angle in the device dialog steps by 5 degrees, not 10
(0..355): a marker often has to line up with a wall that is not on a
10-degree grid.
Tests: three unit tests on iconCqw (the legacy expression reproduced
digit for digit, the runaway plan, the no-view fallback); the infinite
canvas smoke's "same pixel size at zoom 1/4/1/3" assert is turned back
into "scales 4x / 1/3 with the zoom" plus a new one that the marker on
the far plan measures the same as on an ordinary one; the angle step
is pinned in smoke_size_angle_parity. docs/CANVAS.md §6 rewritten.
docs/CANVAS.md is the source of truth (owner-approved 2026-08-03): the
normalised square was never a sheet of paper, only a coordinate system,
and users who drew past its edge could not place devices there.
Storage does not change and there is no migration. What changes is what
the renderers DERIVE from it:
- space-geometry.ts gains contentFrame() — one item per drawn object,
a rank-based outlier vote (median centre, 75th-percentile spread,
10x threshold, majority veto) and a fit-everything box beside the
opening view. contentBounds() is now a thin wrapper over it; the old
-25%..125% envelope is gone — it WAS the bug that made a plan drawn
at 1.5..3.0 frame empty canvas.
- spaceFrame()/spaceCenter() make view_box an optional first-frame hint
used only when there is nothing to frame; iconUnit() keeps auto
placement spacing in proportion (NORM_W for anything inside the old
square, so no layout moves); gridLevels() picks a legible grid step.
- validation.py: coordinates ±4 -> ±5000, sizes 0.001..5000, decor
-1..2 -> ±5000, opening length <= 5000. Garbage insurance, not a
frame — a stored 1e100 is still refused.
Units: test/canvas.test.mjs covers the plan past the square, the
outlier (and the three ways NOT to declare one), corruption, empty
space, a lone marker, image plans and the adaptive grid.
Backend: the limits, and that a config from any released version
validates untouched.
