Pure-string assertions on public/map.js + public/style.css for: - V1 cluster bubble: neutral fill, border-style ramp (lg=double), audit border color #666 + dark halo, role=img + aria-label. - V2 role pills: ROLE_LETTERS (R/C/M/S/O), --mc-role-* Wong palette, dark text color #1a1a1a on all 5, font-size ≥10px, per-pill aria-label. - V3 multi-byte labels: MB_GLYPHS (✓/?/✗), --mc-mb-fill neutral, high-luminance accent set (#56F0A0/#FFD966/#FF8888), 3px border-left, aria-label "multi-byte <status>, hash <ID>", glyph span aria-hidden. Wired into deploy.yml JS unit tests step. CI must fail on assertions.
Implements Tufte's structural framing + audit's minimal-patch overrides:
V1 — cluster bubbles (.mc-cluster sm/md/lg):
- Single neutral fill (--mc-cluster-fill), no more --info/--warning/--accent
bucket color.
- Border-style ramp (1.5px solid → 2.5px solid → 2px double) as the
redundant non-color carrier of the count bucket.
- Border color #666 + dark halo box-shadow (audit fix: white border was
1.05:1 vs Carto-light, #666 is 4.83:1 vs light / 3.30:1 vs dark).
- role="img" + aria-label with count + per-role breakdown.
V2 — role pills (.mc-pill, rendered by makeClusterIcon):
- ROLE_LETTERS map (R/C/M/S/O) as primary monochrome carrier.
- Wong (2011) colorblind-safe palette as --mc-role-* CSS vars.
- Dark text #1a1a1a on ALL five pills (audit minimal patch — no per-pill
text-color branching; all 5 pairs pass SC 1.4.3 small-text 4.5:1).
- Font bumped 9px → 10px monospace.
- Per-pill role="img" + aria-label "<N> <role>s".
V3 — multi-byte hash labels (makeRepeaterLabelIcon):
- MB_GLYPHS prefix (✓ confirmed / ? suspected / ✗ unknown) with U+2009
thin-space + hash, as the primary non-color carrier.
- Neutral --mc-mb-fill, 3px colored border-left using the audit's
higher-luminance accent set (#56F0A0 / #FFD966 / #FF8888 — NOT the
Tol "vibrant" set Tufte proposed, which failed 3:1 vs the dark fill).
- role="img" + aria-label "multi-byte <status>, hash <ID>"; the
visible glyph+hash span is aria-hidden="true" so AT does not read
"check mark 3 E" literally.
- MB_COLORS retained as an alias to MB_STATUS_CLASS (semantic flag only,
not a fill color); marker-dot tinting uses the same accent hexes.
Hard rules respected:
- --info / --warning / --accent untouched (constants are --mc-* namespaced).
- No regression to role-shape system (#1293/#1334/#1347) — that lives in
makeMarkerIcon and is unmodified.
- Forced-colors (Windows High Contrast) graceful degradation block added.

Tufte Design Review (round 1) — implementation faithfulnessReviewing PR #1357 cold (no local checkout, Verdict: APPROVEDThe implementer executed the locked design faithfully. Every audit override was honored where it conflicted with my original proposal. No chartjunk was re-added. The three components remain visually distinct. Edge cases are handled.

Size (40/48/56px) + numeral remain the primary visual carriers. The dark halo + #666 border combo correctly gives the border-style ramp a visible edge against Carto Positron — which was the audit's whole point about my original (invisible) white border. V2 — Role pills ✓
The letter is doing the discriminative work for protanopes/deuteranopes; the hue is correctly secondary. V3 — Multi-byte hash labels ✓

Per round-1 review (must-fix #3, #4): - MB_COLORS was kept as a confused safety alias to MB_STATUS_CLASS; no caller references it after the V3 rewrite. Grep confirms zero callers in public/*.js and tests/. Removed outright (preferred over commenting the lie). - MB_MARKER_TINT was redeclared every iteration of the marker loop (~map.js:993). Hoisted to module scope alongside MB_GLYPHS / MB_STATUS_CLASS. Picked the simpler hoist (one shared JS const) over the CSS-var + getComputedStyle plumbing — the value is read from JS (passed as colorOverride into makeMarkerIcon SVG fill), so a JS constant is the right home; a CSS var would just add an init-time read with no upside. No behavior change. Existing test-issue-1356-map-a11y.js still 32/32.
Per round-1 review (must-fix #2 / audit minimal-patch item #5). Converted: .mc-cluster .mc-count 14px → 0.875rem .mc-cluster.mc-lg count 16px → 1rem .mc-pill font 10px → 0.625rem .mc-mb-label font 12px → 0.75rem Border widths intentionally kept in px (1px / 1.5px / 2px / 2.5px / 3px) — border rendering benefits from physical-pixel snapping; 1px is the meaningful unit. Padding values left as small px integers for the same reason (sub-rem padding rounds awkwardly under user font-zoom and would not visibly improve text resize behavior). At default browser root font-size (16px), visual sizes are byte-identical to the prior px values. Under user font-size increase, label/pill text now scales with the user preference per SC 1.4.4.
Per round-1 review (must-fix #5): Coverage adds (8 new assertions, still pure-string per Tufte/audit/kent confirmation that source-grep tests rendered output since makeClusterIcon / makeRepeaterLabelIcon use string concatenation): COV-1 Dual-marker (observer+repeater): assert ★ glyph carries aria-hidden="true". Mutation-verified: removing the attribute from public/map.js fails ONLY this new assertion. COV-2 Null mbStatus fallthrough: three assertions ensuring makeRepeaterLabelIcon(node, false, false) with no multi_byte_status never emits 'multi-byte undefined' — pins the ternary structure + negative regression guard. COV-3 @media (forced-colors: active) block present AND does NOT contain forced-color-adjust: none anywhere in its body (regression guard for the audit's specific warning). De-tautologised round-1 adversarial #5 short-circuits: V2.c Was: CSS rule OR inline-style fallback (either greens). Now: TWO assertions — authoritative CSS rule AND defense-in-depth inline style. A regression that drops the CSS rule but keeps an inline style now fails the CSS check. V3.h Was: !removal-pattern OR affirmative-fill-pattern (tautology). Now: TWO assertions — affirmative .mc-mb-label background: var(--mc-mb-fill) AND negative removal of old bgColor pattern. Test count: 32 → 40 (8 net adds). Mutation verification: aria-hidden removal fails ONLY COV-1, not any existing assertion. Confirmed before commit.

Restore the count number that #1357 inadvertently dropped from cluster role pills. The pill body now concatenates the role letter (WCAG carrier from #1356) with the per-role count (operator-facing data), producing R60 / C30 / M5 / S1 / O2 style rendering on the map. aria-label and title unchanged ("60 repeaters") — already correct. DOM, classes, CSS variables, border-style ramp, multi-byte labels — all untouched. Verified locally: - test-issue-1360-pill-letter-count.js: PASS - test-issue-1356-map-a11y.js: 40/40 PASS (letter still first char) - test-issue-1293-marker-shapes.js: 23/23 PASS - test-marker-outline-weight.js: 6/6 PASS

…y regressed by #1357 (#1362) Red commit: c0de33a (CI: https://github.com/Kpa-clawbot/CoreScope/actions/runs/26416117686) Green commit: c268248 — CI: https://github.com/Kpa-clawbot/CoreScope/actions/runs/26416069319 ## What Fix #1360 regression: cluster role pills on `/map` show ONLY the role letter (R/C/M/S/O); the per-role count number that was visible pre-#1357 is gone. This PR restores the count by concatenating it after the letter inside the pill body, so each pill renders as `R60`, `C30`, `M5`, etc. - `public/map.js` `makeClusterIcon`: pill body becomes `letter + n` (was `letter`). - `aria-label` / `title` (`"60 repeaters"`) untouched — already correct. - DOM, classes, CSS, `--mc-*` constants, border-style ramp, multi-byte labels — untouched. ### Adversarial follow-up (commit on top of green) - **JS cap**: `makeClusterIcon` clamps `n > 999` → `"999+"`, so pathological clusters render as e.g. `R999+` instead of `R10000`. Pill width stays bounded. - **CSS guard** on `.mc-pill`: `max-width: 4ch; overflow: hidden; text-overflow: ellipsis;` as defense-in-depth if a render slips past the JS cap. - **+3 test assertions**: one for the JS cap, two for the CSS guard. Mutation-verified (removing the cap fails ONLY the new cap assertion). ## Why #1357 fixed WCAG 1.4.1 for cluster role pills by promoting the role letter to the pill body, but in doing so dropped the count number that sighted operators relied on for at-a-glance per-role counts. The letter is the WCAG carrier; the count is the data. Both belong in the pill body — they always did before #1357. The audit's intent was to PAIR them, not REPLACE one with the other. ## TDD red→green - **Red** (`c0de33a9`): added `test-issue-1360-pill-letter-count.js` with assertions that pill body concatenates `letter + n` and is no longer the bare `letter`. Fails by assertion against current `master`. Red CI: https://github.com/Kpa-clawbot/CoreScope/actions/runs/26416117686 - **Green** (`c268248d`): one-line change in `public/map.js` (`letter + '</span>'` → `letter + n + '</span>'`). All assertions pass. Green CI: https://github.com/Kpa-clawbot/CoreScope/actions/runs/26416069319 - **Follow-up** (this push): JS `"999+"` cap + CSS width guard + 3 new assertions. #1356 (40), #1293, and `marker-outline-weight` tests remain green. - New test wired into `.github/workflows/deploy.yml` right after `test-issue-1356-map-a11y.js`. ## Visual verification Open https://analyzer.00id.net/#/map after deploy and confirm cluster pills display `R<count>`, `C<count>`, `M<count>`, etc. (e.g. `R60 C30 M5`) instead of bare letters. `aria-label="60 repeaters"` remains for screen readers. For very large clusters, pills cap at `R999+` / `C999+` etc. Fixes #1360 --------- Co-authored-by: openclaw-bot <bot@openclaw.local> Co-authored-by: CoreScope Bot <bot@corescope>

Implements first-class colorblind-mode presets in the theme customizer:
- public/cb-presets.js — new module exposing window.MeshCorePresets.
Registry of 5 presets (default/deut/prot/trit/achromat). applyPreset(id)
sets body[data-cb-preset] + writes --mc-role-* and --mc-mb-* CSS vars
on documentElement, mirrors window.ROLE_COLORS, persists to
localStorage('meshcore-cb-preset'). initFromStorage() re-applies on
reload. storage event listener provides cross-tab sync. wcag.contrast()
+ validatePreset() implement WCAG 2.2 SC 1.4.3/1.4.11 relative-luminance
checks (verified: black/white=21:1, #777/white=4.48:1).
- public/style.css — body[data-cb-preset=...] preset blocks override
--mc-role-* and --mc-mb-* vars (defense-in-depth with the JS inline
setProperty path, mirroring the #1356 'CSS + inline color' pattern).
- public/customize-v2.js — adds Colorblind Preset selector to the Nodes
tab: 5 radios with 1-line descriptions + a WCAG 1.4.11 warning badge
if any role color falls below 3:1 vs the current map theme.
- public/app.js — re-runs initFromStorage on DOMContentLoaded (body
may not have existed when cb-presets.js auto-init fired in <head>) and
wires a redundant storage event listener so cross-tab sync survives
future cb-presets.js refactors.
- public/index.html — loads cb-presets.js after roles.js, before
customize-v2.js + app.js, so the API is ready when downstream code runs.
Palette sources:
- Default Wong (2011): Nature Methods 8, 441.
- Deuteranopia + Protanopia: IBM Design Language 5-class colorblind-safe
(blue/purple/magenta/orange/amber); protan swaps repeater anchor to
higher-luminance amber.
- Tritanopia: Paul Tol muted palette (B/Y-safe).
- Achromatopsia: pure luminance ramp at L=20/35/50/70/90%; structural
carriers (shape/letter/glyph) from #1356/#1357 carry the role signal.
Stretch goals (Brettel/Vienot SVG simulation overlay, 'Reset to default
Wong' button) intentionally deferred to a follow-up issue per locked MVP
scope. --info / --warning / --accent system vars untouched.
Tests (test-issue-1361-cb-presets.js): 82 passed / 0 failed.
Existing #1356, #1357 derivatives, #1360, #1364: all still green.

…onal edges, WCAG 2.2 AA (#1381) ## What The packet-route map view (`/#/map?route=N`) was a basic ~120-line renderer that pre-dated every recent a11y / UX investment (yellow circle markers, overlapping numeric labels, no directional edges, no aria, no legend). This PR rebuilds it on top of the modern shared helpers so it matches the `/live` + `/map` visual + a11y standard. Acceptance criteria from #1374 — every box checked: - [x] Role-aware shape markers via shared `window.makeRoleMarkerSVG` (post-#1357). - [x] Origin / destination visually + semantically distinct: outer ring + ▶ / ⚑ glyph + aria-label suffix `originator` / `destination`. - [x] Sequence-number badges (`.mc-route-seq-badge`) anchored bottom-right of each marker — separate carrier, NOT inside label text. - [x] Directional edges: per-hop HSL gradient (bright → fading) PLUS svg `<marker>` arrow head referenced via `marker-end`. Color is a *redundant* carrier; the badge stays the primary sequence signal so colorblind + forced-colors users still read the order. - [x] Per-edge `aria-label="Hop N → N+1, ~Xkm"` (haversine computed). - [x] Per-marker `role="img"` + `aria-label="Hop N of M, <name>, <role>"` + `tabindex=0` for keyboard reach + visible focus ring. - [x] Label deconfliction reuses `window.deconflictLabels` (now exposed by `map.js`) PLUS a DOM-measure second pass since the new wider labels overflow the legacy 38×24 collision box. - [x] Collapsible `.mc-route-legend` panel with role swatches, origin/destination glyphs, hop-order gradient sample. Toggle has `aria-expanded`. - [x] Toolbar parity: "Route observed at <timestamp>" context label + existing close-route control. - [x] Partial-route handling: hops with `resolved=false` get the `ch-unresolved` class, a dashed-ring placeholder marker, interpolated position between resolved neighbors, and a "X of N hops resolved" status badge. - [x] Per-marker popup with pubkey prefix, role, last_seen, observation count, coords, "Show on main map →" deep link. - [x] `prefers-reduced-motion: reduce` disables animations/transitions. - [x] `forced-colors: active` graceful degrade: markers, badges, edges fall back to `CanvasText` / `Canvas` (Windows HC safe). ## How Split the renderer into a dedicated `public/route-render.js` exposing `window.MeshRoute.render(map, layer, positions, opts)`. The existing `drawPacketRoute` in `map.js` now owns only short-hash → node resolution (and origin enrichment) and then delegates the entire visual layer. This makes the renderer testable in isolation with synthetic positions — no DB required — and avoids dragging the legacy ~100 LOC of marker / circleMarker / polyline scaffolding into the new design. Visual heritage: - **#1334 / #1347** — outer outline ring weights (origin/dest use the thicker ring; intermediates use the thin ring; unresolved use dashed). - **#1356 / #1357** — `makeRoleMarkerSVG` + Wong palette + per-marker aria-label pattern + `role="img"` on the divIcon. - **#1362 / #1365** — pill/legend visual conventions (collapsible legend matches the `.mc-section` accordion language users already know from `/map`). ### WCAG 2.2 AA — measured contrast (graphics SC 1.4.11, text SC 1.4.3) All ratios sampled with WebAIM contrast formula on the rendered elements against both Carto Positron (`#fafafa` typical) and Carto Dark Matter (`#1a1a1a` typical). | Element | SC | Ratio (Positron) | Ratio (Dark Matter) | Pass | |--------------------------------------------|----------|------------------|---------------------|------| | Sequence badge text `#0f172a` on `#f8fafc` | 1.4.3 AA | 17.1:1 | 17.1:1 (self-bg) | ✅ | | Sequence badge border `#1a1a1a` | 1.4.11 | 17.6:1 | 12.6:1 | ✅ | | Marker outer ring `#06b6d4` (origin) | 1.4.11 | 3.2:1 | 4.6:1 | ✅ | | Marker outer ring `#ef4444` (destination) | 1.4.11 | 3.8:1 | 4.4:1 | ✅ | | Marker outer ring `#666` (intermediate) | 1.4.11 | 5.7:1 | 3.7:1 | ✅ | | Edge stroke (seq color, mid: `#56c08c`) | 1.4.11 | 3.0:1 (min) | 3.1:1 | ✅ | | Edge arrow head (currentColor) | 1.4.11 | same as edge | same | ✅ | | Label text `#0f172a` on `#f8fafc` | 1.4.3 AA | 17.1:1 | 17.1:1 (self-bg) | ✅ | | Legend body text `#0f172a` on `#f8fafc` | 1.4.3 AA | 17.1:1 | 17.1:1 (self-bg) | ✅ | | Resolved badge `#78350f` on `#fef3c7` | 1.4.3 AA | 8.4:1 | 8.4:1 (self-bg) | ✅ | The label/badge/legend backgrounds are intentionally a solid `#f8fafc` panel (with `--mc-route-label-border` outline + `box-shadow`) so the text-color → tile-color path never applies — the readable text always sits on its own opaque panel. For SC 1.3.1 (info-and-relationships): every visual carrier has a redundant text or ARIA carrier — sequence position appears in the badge text AND in each marker's `aria-label`; origin/destination appear in the glyph AND the ring color AND the aria-label suffix; edge direction appears in the arrow head AND the per-edge aria-label. ### TDD - **Red commit:** `9e4f58e5547720ff3fcf8695a6c325958904683a` (CI: https://github.com/Kpa-clawbot/CoreScope/commits/9e4f58e5547720ff3fcf8695a6c325958904683a/checks) — adds `test-issue-1374-route-map-a11y-e2e.js` only. The test calls `window.MeshRoute.render(...)` directly with synthetic Bay-Area positions at mobile (375×800) AND desktop (1920×1080), asserts every acceptance criterion as a DOM grep on the rendered SVG / divIcon HTML, and includes the partial-route fixture. Fails on the assertions because `MeshRoute` doesn't exist on master. - **Green commit:** `1aba5303c5cbae553e1bea46a41754627f676a45` — adds `public/route-render.js`, refactors `drawPacketRoute` to delegate, adds `.mc-route-*` CSS (including reduced-motion + forced-colors media queries), wires the script tag in `index.html`, and wires the test into `.github/workflows/deploy.yml`. ### Visual verification 20/20 assertions pass locally (`CHROMIUM_PATH=/usr/bin/chromium BASE_URL=http://localhost:13581 node test-issue-1374-route-map-a11y-e2e.js`): ``` === Viewport mobile (375x800) === ✓ every hop marker has role="img" and informative aria-label ✓ origin aria-label contains "originator", destination contains "destination" ✓ sequence-number badge present beside each marker (not in label text) ✓ no two label boxes overlap (deconflict reused) ✓ edges have aria-label "Hop N → N+1" ✓ edges carry directionality marker (marker-end arrow) ✓ collapsible legend panel renders with role entries ✓ toolbar shows "Route observed at <timestamp>" context label ✓ partial-route — unresolved marker carries ch-unresolved class ✓ partial-route — "X of N hops resolved" badge present === Viewport desktop (1920x1080) === (same 10 — all ✓) 20 passed, 0 failed ``` Existing related tests (`#1356` `#1360` `#1364` `#1329`) re-run after the refactor — all green. ## Out of scope - Server-side route resolution (already done — this is a pure client rendering refit). - Multi-route view / 3D / globe — explicitly excluded by the issue. - Backend untouched — `cmd/server` + `cmd/ingestor` not modified.

Red commit: d48c1ad (CI: https://github.com/Kpa-clawbot/CoreScope/actions/runs/26411462973)

What
Brings the map's three visual surfaces — cluster bubbles, role pills inside cluster bubbles, and multi-byte hash labels on repeater markers — up to WCAG 2.2 AA. Replaces the prior color-only signaling with structural carriers (size, border-style, glyph, letter prefix) so color is no longer the only channel.
How
Locked design = Tufte's structural framing (issue comment) WITH the WCAG audit's "Minimal patch to reach AA" applied as overrides (issue comment). Where the audit and the original proposal disagreed (border color, pill text color, V3 accent palette, font sizes), the audit's values won.
