* feat(scatter): add bubble variant for three-value comparisons
Bubble chart as a Scatter variant per the issue #62 triage: x and y on
shared zero-based linear scales, bubble AREA proportional to the third
value (r = K*sqrt(size)), one accent bubble, ink-opacity ramp as ink-mass
compensation, largest-first paint order.
scripts/verify-bubble.py derives both axis scales and the area constant
from the set itself (Theil-Sen, leave-one-out) and holds every bound
label and tick against the mark it describes; test-verify-bubble.py
exercises both polarities. Bindings are bubble-specific (data-size,
data-name, data-tick) rather than data-series, so verify-slopegraph.py
never claims a bubble file and neither checker needs scope carve-outs.

* fix(bubble): report a bubble whose peers cannot describe a scale
A bubble holding the only distinct value on an axis was skipped by the
leave-one-out residual test — its own fit is degenerate, and the full-set
fit passes through wherever it was drawn, so a wrong coordinate shipped
clean. Report it as unverifiable instead of skipping it.

* chore: bump to 2.6.3 and register bubble gates
Ridgeline (#143) landed on 2.6.2, colliding with this branch's bump, so
re-bump past it. Also add the bubble gate commands to the maintainer
policy's local_commands, matching what ridgeline registered.

* chore: bump to 2.6.5
The mermaid fix (#131) landed on 2.6.4, colliding with this branch's
bump again. Re-bump past it.

* feat(line): add ridgeline as a Line variant
One distribution per series, stacked at a fixed pitch on a single shared
amplitude. Ships three static examples (light, dark, full editorial),
the type-line.md spec, and a geometric gate.
verify-ridgeline.py derives the figure's one amplitude and its baseline
pitch from the figure itself, then holds every vertex to both. It also
checks the drawn baseline rules, the shared bin scale, absolute M/L/Z
only, the overlap ceiling, the focus pairing and every label binding.
test-verify-ridgeline.py proves each check in both polarities and pins
the scope treaty with the sibling Line gates.
The contract binds data-bins on a <path>, which no other chart in the
repo declares, so verify-slopegraph and this gate never claim the same
file.

* fix(verify-ridgeline): read exponent coordinates as numbers, not commands
parse_d scanned for [A-Za-z] independently of the numbers, so the `e` in a
valid scientific-notation coordinate such as 4.4e2 was counted as a path
command. The explicit-command rule then rejected a correct ridgeline with a
message about command counts.
Tokenise the d attribute left to right with the number branch tried first,
so an exponent is consumed as part of its number. A letter that survives
that branch is a real command and still faces the M/L/Z vocabulary check;
anything else leaves the path unreadable, which stays a finding.
Adds both polarities: a shipped coordinate rewritten as 4.4e2 must verify,
and a falsified one written the same way must not.

Documents the dumbbell in type-bar.md's existing Variants section,
alongside grouped and stacked bars. Reference-only, matching the
precedent those two set and the one #100 landed for datalake: no
example assets, no gallery entries.
Not a new visual type. The count stays at 28 and SKILL.md is untouched
-- no selection-table row, no frontmatter hook, no manifest description
change.
Covers layout on the shared 1000x500 composition, an element pattern,
and five honesty rules: no truncated axis, one scale with both endpoints
labelled, the connector is a gap and not a trajectory, a stated row
order, and no imputed or silently dropped endpoints.
Two of those rules live in a formula rather than a drawing, so they ship
as a checker with adversarial fixtures per ADR 0005:
- Domain resolution is exhaustive over sign. A rule phrased as
"all-positive / all-negative" silently drops data that only touches
zero, and drops all-zero data entirely -- where floor == ceil == 0 and
the position formula divides by zero. resolve_domain() partitions the
space, guarantees ceil > floor, and returns a finite fallback span for
all-zero input so every dot lands on the floor.
- Non-text contrast is carried by the boundary, not the fill. Accent on
paper is 2.86:1 skin-wide, and shape redundancy does not waive WCAG
1.4.11, so the solid endpoint takes a 1px ink stroke (11.82:1) and the
connector 55% ink on light / 40% on dark (3.19:1 and 3.24:1). The
checker reads these tokens out of the reference, so prose and
thresholds cannot drift apart.
scripts/test-verify-dumbbell.py covers both polarities: all-zero,
zero-touching, mixed-sign, empty and non-finite input, observed-extremes
truncation, and the sub-3:1 treatments this replaces. Wired into CI and
CONTRIBUTING alongside the treemap and geometry gates.
Other things the geometry and house style forced: the focal bar pattern
(12% tint plus accent stroke) does not survive at a 6px dot, so the pair
separates by fill weight; a 64px row pitch from y=96 overflows the y=420
plot floor at seven rows, so pitch and origin are tabulated per row
count; rgb(45,49,66) IS the dark paper, so light-theme hairlines
composite to 1.000:1 and must invert; label offsets keyed to start/end
put both labels inside the pair on a decreasing row; a value on the
domain floor collided with its category label; and the value axis was
missing the Geist Mono 7px title every other cartesian type carries.
