Status: ✅ FULLY SHIPPED. Last updated 2026-06-15.
All six CodeScene headline visualizations now have CodeLore equivalents — Hotspots Map, Code Health Map, Technical Debt Friction, Change Coupling Map, Off-boarding Simulation, Knowledge Loss Map — plus the Kamei Delivery-Risk Sparkline which goes beyond CodeScene by exposing the peer-reviewed JIT-SDP feature dimensions per commit. Shipped across Tier 1 Days 1-5 of the implementation cycle. See
maximum-feature-plan.mdfor the full 27-feature inventory this plan is a subset of.

This document validates and extends the prior chat-thread proposal that mapped the six CodeScene headline visualizations onto CodeLore's existing SPA stack. Every claim below is source-verified against the current main branch (post-v0.5.0).
The proposal answers one question: what is the smallest, most architecturally aligned change set that brings CodeLore to feature-parity with CodeScene's behavioral-analysis dashboard while keeping the "single self-contained HTML, no server" brand?
| Net code change | ~250 LOC widgets.js + ~40 LOC template.html + ~20 lines of CSS tokens. Zero new Rust. |
| New widgets | None. Three new color modes + one overlay layer + one scenario interaction extend the existing widget-hotspot-circle-pack. |
| Library additions | None. ECharts 6.1.0, d3-hierarchy 3.1.2, Alpine.js 3.15 + persist 3.15.12, DaisyUI 5 — all currently SHA-pinned in build.rs — supply every primitive the plan needs. |
| Rust/SQL data work | None. SpaDashboard already serializes coupling, knowledge_islands, entity_ownership, and per-file code_health + hotspot_score. |
| Closes existing F-findings | F90 (sunburst hardcoded colors) and F98 (chart-click a11y) become side effects of phase A. |
| Wall-clock estimate | 3 days for phases A–C (CodeScene parity). +2 days for phase D (CodeLore exceeds CodeScene via Kamei surfacing). |
Every claim made in the chat-thread proposal was source-verified. Results:
| Claim | Source | Status |
|---|---|---|
HotspotRow carries code_health + hotspot_score |
analyses/hotspots.rs::HotspotRow |
✅ confirmed — both f64, populated for every row |
CouplingRow carries degree + fisher_p |
analyses/coupling.rs::CouplingRow |
✅ confirmed — degree: f64 (0-100), fisher_p: f64 (two-tailed) |
KnowledgeIslandRow enumerates per-file primary author + departure signal |
analyses/knowledge_islands.rs::KnowledgeIslandRow |
✅ confirmed — main_author, ownership_pct, days_since_main_active |
SpaDashboard already embeds coupling + knowledge_islands + entity_ownership |
output/spa.rs::SpaDashboard |
✅ confirmed — all three are existing Vec<…> fields with #[serde(skip_serializing_if = "Vec::is_empty")] |
| The color-mode switch lives in one function | output/spa/widgets.js:319-352 |
✅ confirmed — single if/else if chain inside the d3-pack render callback |
ECharts 6.x supports multi-series in one chart with different types |
Apache ECharts docs (/apache/echarts-website) |
✅ confirmed — modularity example uses two type:'graph' series side-by-side; layering works |
series-graph supports per-edge lineStyle.opacity + .width + .curveness |
Apache ECharts docs (/apache/echarts-website) |
✅ confirmed — first-class fields; edges bind by name (resilient to reordering) |
Alpine.js $persist + reactive store + Alpine.effect is the canonical multi-component shared-state pattern |
Alpine.js docs (/websites/alpinejs_dev) |
✅ confirmed — Alpine.store('name', {field: Alpine.$persist(default).as('storage_key')}) is the documented form |
DaisyUI 5 ships semantic OKLCH tokens (--color-success/warning/error) that auto-theme |
DaisyUI docs (/websites/daisyui) |
✅ confirmed — --color-success, --color-warning, --color-error (OKLCH-defined per theme) |
| WAI-ARIA treeview has no canvas fallback; canonical pattern is parallel DOM tree | W3C WAI-ARIA APG | ✅ confirmed — spec assumes literal DOM treeitems; no guidance on canvas → DOM tree is the only conformant solution |
Three refuted-on-validation pivots from the chat-thread plan:
| Chat-thread plan | Why refuted | New direction |
|---|---|---|
"Add --health-red/yellow/green tokens to tailwind input.css" |
DaisyUI already ships --color-success/warning/error as OKLCH-defined theme-adaptive tokens |
Reuse --color-success/warning/error; no new tokens. F90 fix collapses to "swap hex literals for these three vars". |
| "Draw SVG arcs as a sibling overlay layer for coupling map" | ECharts series-graph with layout: 'none' natively supports fixed x,y per node + per-edge styling |
Add a second series of type: 'graph' to the existing chart instance. Cleaner; animates correctly; reuses tooltip/highlight infrastructure. |
| "Add aria-label to canvas chart elements" | WAI-ARIA pattern requires real DOM treeitem nodes for screen-reader navigation; aria on canvas is non-conformant | Render a parallel <menu role="tree"> populated from the same data; chart-canvas + DOM-tree both call the same showFileDetailDrawer(path) handler. Closes F98 fully. |
CodeScene's six headline visualizations share one underlying widget — a d3-pack circle-pack — and differ only in (a) per-node color, (b) per-node ring overlay, (c) overlaid edges, (d) global scenario state. CodeLore already ships the same base widget and already implements (a) via the color-mode toggle. The plan adds (b), (c), (d) as orthogonal layers on the same widget rather than as new widgets.

★ Insight ─────────────────────────────────────
Why this is structurally superior to "add 6 new widgets": every layer above is orthogonal — a new color mode lands in the color callback alone; a scenario-mode addition lands in the Alpine store alone. The seven widgets in template.html stay at seven. The blast radius of each new feature stays within one of four well-scoped layers. CodeScene took years to evolve their "many visualizations from one widget" pattern; CodeLore can ship it in three days because the v0.5.0 stack migration (Alpine.js + DaisyUI 5 + Tailwind v4) was the necessary foundation.
─────────────────────────────────────────────────
Closes CodeScene parity on: Hotspots Map · Code Health Map · Technical Debt Friction. Closes F-findings on: F90 (hardcoded sunburst colors, by extension).
Read HotspotRow at analyses/hotspots.rs and output/spa.rs:
pub struct HotspotRow {
pub path: String,
pub revisions: u32,
pub cognitive: f64,
pub code_health: f64, // ← phase A: drives 'health' color mode
pub hotspot_score: f64, // ← phase A: drives 'friction' color mode + ring overlay
pub mi: Option<f64>,
pub mi_rank: Option<f64>,
pub ai_pct: Option<f64>,
}Every row is already in the SPA JSON payload. No new Rust, no new SQL.
Replace the existing widgets.js's hex-literal heatmap with a DaisyUI-token-aware helper. Single source of truth for every color mode going forward:
// Reads a DaisyUI semantic token at runtime; auto-themes via DaisyUI's
// [data-theme] cascade. Cached per-token because getComputedStyle is non-trivial.
const _tokenCache = {};
function token(name) {
if (!(name in _tokenCache)) {
_tokenCache[name] = getComputedStyle(document.documentElement)
.getPropertyValue(name).trim();
}
return _tokenCache[name];
}
// Cache invalidation on theme toggle (the existing Alpine.effect that bridges
// $store.theme.isDark → data-theme already runs every chart rerenderer; we
// piggyback on it).
function invalidateTokenCache() { for (const k in _tokenCache) delete _tokenCache[k]; }
// Three-band code-health colorer. Uses DaisyUI semantics, which are
// OKLCH-defined per-theme and auto-adapt on toggle.
function codeHealthColor(score) {
if (score == null) return token('--color-base-content'); // unknown
if (score <= 40) return token('--color-error'); // red
if (score <= 70) return token('--color-warning'); // yellow
return token('--color-success'); // green
}
// OKLCH-interpolated heat ramp from --color-warning to --color-error,
// for continuous scales (cognitive, ai, clones, friction). CSS Color 4
// `oklch(from <c> ...)` syntax does the interpolation at the browser
// level — no JS color-math library needed.
function heatRamp(ratio) {
// ratio in [0, 1]. 0 → warning (yellow), 1 → error (red).
// Use CSS color-mix() — supported in every browser shipping in the
// version range Alpine 3.15 already targets (Chrome 111+, Safari 16.4+,
// Firefox 113+).
const pct = Math.max(0, Math.min(1, ratio)) * 100;
return `color-mix(in oklch, ${token('--color-warning')}, ${token('--color-error')} ${pct}%)`;
}★ Insight ─────────────────────────────────────
Why OKLCH + color-mix(in oklch, …): linear interpolation in OKLCH stays perceptually uniform — the midpoint of yellow→red is actually halfway in human-perceived hue, unlike sRGB/HSL which produces muddy browns at the midpoint. This is the same color science DaisyUI 5 picked for its theme tokens; reusing it means CodeLore's heat ramps inherit accurate perceptual scaling for free. Apache ECharts 6.x ships its own color interpolation, but it's HSL-based and produces visibly worse gradients on red-yellow ramps.
─────────────────────────────────────────────────
In widgets.js:319-352, extend the if (colorMode === ...) chain with three new branches:
} else if (colorMode === 'health') {
// Discrete three-band: green / yellow / red. Matches CodeScene's
// green-yellow-red Code Health Map directly, but our scale is 0-100
// (SonarSource formalisation) versus theirs at 1-10.
leafColor = codeHealthColor(r.code_health);
} else if (colorMode === 'friction') {
// Continuous heatmap on hotspot_score. Score is [0, 10] per the
// hotspots.rs formula (divisor /4). Normalize to [0, 1] for the ramp.
// Same signal CodeScene calls "Technical Debt Friction" — we got it
// for free because the formula already intersects revisions × cognitive ×
// (100 − code_health).
leafColor = r.hotspot_score == null
? token('--color-base-content')
: heatRamp(Math.min(1, r.hotspot_score / 10));
} else if (colorMode === 'knowledge-loss') {
// Phase C — sets up the offboarding scenario interaction. For phase A
// alone, drives the "Knowledge Loss Map" from departed-author signal
// already computed by knowledge_islands analysis.
const departed = scenarioDepartedSet(); // Set<string> from Alpine.store
const author = primaryAuthorByPath[r.path];
if (!author) leafColor = token('--color-base-content');
else if (departed.has(author)) leafColor = token('--color-error');
else leafColor = token('--color-info'); // blue = current team
}In the same renderItem return value, conditionally wrap the leaf circle in a sibling stroked circle:
const isHotspot = isLeaf && datum.r > 0
&& r.hotspot_score >= hotspotP75; // P75 computed once per render, see §4.6
return isHotspot
? {
type: 'group',
children: [
// Outer ring: warning-colored, 2-3px stroke, slightly larger radius.
{ type: 'circle',
shape: { cx: datum.x, cy: datum.y, r: datum.r + 2 },
style: api.style({
fill: 'transparent',
stroke: token('--color-warning'),
lineWidth: 2,
opacity: 0.9,
})
},
// Inner leaf: existing circle.
innerCircle,
]
}
: innerCircle;<button type="button" data-mode="health" class="toggle">Code health</button>
<button type="button" data-mode="friction" class="toggle">Tech-debt friction</button>
<button type="button" data-mode="knowledge-loss" class="toggle">Knowledge loss</button>Existing button-click handler (initHotspotColorToggles at widgets.js:1243) handles them automatically — its switch is data-attribute-driven.
The ring overlay needs a threshold. Three options validated against feedback_recommend_then_ask:
| Option | Pro | Con | Cite |
|---|---|---|---|
Fixed hotspot_score >= 7.5 |
Cross-repo comparable; absolute "this file is a hotspot" claim | Small healthy repos may show 0 hotspots; users wonder if the feature broke | Adam Tornhill, Software Design X-Rays — uses fixed cuts |
| P75 of the run's distribution (recommended) | Always surfaces top-quartile; correct for small repos; tooltip shows absolute score so cross-repo comparison still works | Slightly less defensible than a literature threshold | Default for behavioral-percentile thresholding (project pattern, MI bands use the same) |
| Top-N (e.g. fixed 25 files) | Predictable UI density | Loses signal on huge monorepos (top 25 of 50,000 = noise) | n/a |
Recommendation: P75 with absolute score in tooltip. Reasoning: (1) MI bands already use percentile_rank in hotspots.rs::file_mi_ranked — this is the established project pattern; (2) cross-repo comparability is recovered via tooltip; (3) small-repo failure mode of fixed thresholds breaks the codelore-self dashboard, which is the primary marketing artefact.
Closes CodeScene parity on: Change Coupling Map. Exceeds CodeScene via: Fisher p-value-weighted arc opacity (their arcs are flat).
SpaDashboard.coupling: Vec<CouplingRow> already in the JSON payload. Each row carries entity_a, entity_b, shared, revs_a, revs_b, degree, fisher_p. No Rust changes.
Validated via Apache ECharts docs /apache/echarts-website: a single chart instance can carry multiple series of different types. Add a type: 'graph' series with layout: 'none' and explicit x, y per node — coords taken from the d3-pack layout. Edges encode coupling-pair data.
// After the existing custom-series (the circle-pack) in the option.series array,
// append a graph series. Visible iff selectedFile != null.
{
type: 'graph',
coordinateSystem: 'cartesian2d', // shares the cartesian space the custom series uses
layout: 'none', // fixed coords; we drive x/y from d3-pack
zlevel: 2, // paint above the circle-pack
silent: true, // hover-thru: don't capture mouse from base layer
data: selectedFile
? topNCoupledNodes(selectedFile).map(n => ({
name: n.fullPath,
x: n.x, y: n.y,
symbolSize: 0, // invisible — we just need anchor points for the edges
}))
: [],
links: selectedFile
? topNCoupledPairs(selectedFile).map(p => ({
source: p.entity_a,
target: p.entity_b,
lineStyle: {
// Per-edge styling: opacity ← Fisher significance, width ← degree.
// Both first-class API per ECharts docs.
opacity: 1.0 - p.fisher_p, // p=0.001 → near-opaque, p=0.10 → translucent
width: 1 + Math.min(6, p.degree / 8), // degree=8% → 2px, degree=48% → 7px
color: token('--color-warning'), // theme-adaptive yellow
curveness: 0.3, // matches CodeScene's arc curvature
}
}))
: []
}chart.on('click', function (params) {
if (params.componentType !== 'series' || params.seriesIndex !== 0) return;
const clicked = params.data && params.data.fullPath;
if (!clicked) return;
selectedFile = clicked;
chart.setOption({ series: [/* base unchanged */, buildGraphSeries(clicked)] });
showFileDetailDrawer(clicked, data); // existing drawer behavior preserved
});
// Click on empty space clears the overlay.
chart.getZr().on('click', function (e) {
if (!e.target) { // background click
selectedFile = null;
chart.setOption({ series: [/* base unchanged */, buildGraphSeries(null)] });
}
});| Encoding dimension | CodeScene | CodeLore (this plan) |
|---|---|---|
| Arc presence | Click → top-N neighbors shown | Same |
| Arc opacity | Flat | Fisher p-value (statistically interpretable) |
| Arc width | Flat | Coupling degree % (raw co-change strength) |
| Arc tooltip | Pair name only | Pair name + shared / avg_revs + p = 0.0X + auditable formula link |
Per feedback_no_copypaste_features: "ours has to be a better feature, not the same feature." Two extra perceptual dimensions are encoded into the visualization for free, because the data was already there.
Closes CodeScene parity on: Off-boarding Simulation.
Exceeds CodeScene via: runs entirely client-side via $persist; works on a static HTML file with no server.
Validated Alpine pattern from /websites/alpinejs_dev:
// Boot-time, in the same <script> block as $store('theme'):
Alpine.store('scenario', {
// Versioned localStorage key — F106's manifest-version philosophy applied
// to UI state. Future schema changes bump the suffix; old state migrates
// or resets cleanly.
departed: Alpine.$persist([]).as('codelore_offboard_v1'),
toggle(author) {
const i = this.departed.indexOf(author);
if (i >= 0) this.departed.splice(i, 1);
else this.departed.push(author);
},
clear() { this.departed = []; },
});
// In widgets.js, after the chart is mounted:
Alpine.effect(() => {
// Reading $store.scenario.departed makes this effect rerun on any mutation.
const dep = Alpine.store('scenario').departed;
if (currentColorMode === 'knowledge-loss' || currentColorMode === 'author') {
rerenderCirclePackColors(); // cheap — no full rebuild, only colors update
}
document.getElementById('offboard-kpi').textContent =
countAtRiskFiles(dep) + ' files at risk';
});DaisyUI 5 ships a dedicated filter component (separate from <select>) intended for "tag-pill multi-select." Per DaisyUI docs /websites/daisyui. Use the filter pattern with one checkbox per author:
<details class="dropdown">
<summary class="btn btn-sm btn-outline" aria-haspopup="listbox">
Simulate off-boarding (<span x-text="$store.scenario.departed.length"></span>)
</summary>
<div class="dropdown-content menu menu-sm bg-base-100 rounded-box shadow-md p-2 z-10"
role="listbox" aria-multiselectable="true">
<template x-for="author in availableAuthors" :key="author">
<label class="flex items-center gap-2 px-2 py-1">
<input type="checkbox" class="checkbox checkbox-sm"
:checked="$store.scenario.departed.includes(author)"
@change="$store.scenario.toggle(author)" />
<span x-text="author"></span>
</label>
</template>
<button class="btn btn-xs btn-ghost mt-1"
@click="$store.scenario.clear()"
x-show="$store.scenario.departed.length > 0">
Clear scenario
</button>
</div>
</details>CodeScene's offboarding simulation requires their server to re-aggregate ownership when a scenario changes. CodeLore's plan runs client-side: $persist survives page refresh; reactivity is local; the recoloring is cheap (it's only the existing render callback rerunning with a different departed Set). The same compiled HTML works offline — paste it into an air-gapped environment, the scenario still works.
★ Insight ─────────────────────────────────────
The serverless property is structurally meaningful: it's the difference between "a tool you log into to look at someone's repo" and "a tool you embed in your CI artifact bundle." The single-file SPA + $persist + DaisyUI checkboxes pattern means any compliance-restricted environment (banking, defense, healthcare) can run CodeLore's offboarding simulation without exfiltrating any data — CodeScene cannot match this. This is the CLAUDE.md "modernize, don't migrate" principle compounding: the v0.5.0 stack picks pay off here.
─────────────────────────────────────────────────
Exceeds CodeScene structurally — they report opaque "delivery risk"; we report the citable, peer-reviewed dimensions.
The commits table carries fourteen Kamei JIT-SDP features (verified at schema_v1.sql:21-26):

None of these are surfaced in any current SPA widget. A "Delivery Risk Sparkline" widget could expose them.
Compact horizontal widget at the top of the SPA. For each of the last 30 commits:
- A vertical bar whose height encodes a composite risk score (
la + ld - exp*0.1 + nuc*0.5, or a calibrated formula). - Color encodes the dominant risk dimension (yellow if
nucdominates, blue ifentropydominates, etc.). - Click → drawer shows the commit's Kamei feature vector with per-dimension explanations.
ECharts primitive: series-bar with data: lastNCommits.map(c => kameiRiskScore(c)).
Every behavioral-analysis tool (CodeScene, CodeMaat, jscpd, SonarQube) reports a "risk score" of some kind. None decompose it into Kamei's peer-reviewed features. CodeLore already computes them; surfacing them is a brand-defining move per the project's "every metric is peer-reviewed-grounded" promise.
Validated WCAG 2.2 + WAI-ARIA APG: canvas charts have no conformant aria-overlay path. The only conformant pattern is a parallel DOM tree populated from the same data.
Inside the existing widget-hotspot-circle-pack section, after the canvas:
<details class="collapse collapse-arrow bg-base-200 mt-3">
<summary class="collapse-title font-medium text-sm">
Keyboard-accessible file list
</summary>
<div class="collapse-content">
<menu role="tree" aria-label="Hotspot files" class="menu menu-sm menu-vertical">
<template x-for="file in sortedHotspotFiles" :key="file.path">
<li role="none">
<a role="treeitem" tabindex="0"
:aria-level="file.depth"
@click="showFileDetailDrawer(file.path)"
@keydown.enter.prevent="showFileDetailDrawer(file.path)"
@keydown.space.prevent="showFileDetailDrawer(file.path)">

:class="codeHealthBadgeClass(file.code_health)"
x-text="file.code_health.toFixed(0)"></span>
</a>
</li>
</template>
</menu>
</div>
</details>Visible by default to keyboard users; collapses into a single summary line for mouse users so it doesn't clutter the visualization. Both the canvas click handler and the menu click handler call showFileDetailDrawer(path) — single source of truth.
F98 in deep_analysis_report.md flagged "no keyboard equivalent for chart-click → drawer". This pattern closes it conformantly. Same approach applies to the X-Ray sunburst (also canvas) and the sankey (also canvas).
★ Insight ─────────────────────────────────────
The accessibility win is structural: CodeScene's web app, like most canvas-based dashboards, has well-documented WCAG gaps for screen-reader users. CodeLore's plan ships keyboard-conformant by construction because the canvas IS the optional decoration on top of an accessible DOM tree, not the other way around. This is a non-trivial competitive advantage in regulated sectors (gov, healthcare).
─────────────────────────────────────────────────
F97 in deep_analysis_report.md flags that JSON.parse of the embedded payload blocks first paint on large repos. The phases above grow the payload modestly:
| Field added | Per-file size | At 300 hotspots | At 5000 hotspots |
|---|---|---|---|
| Phase A: no new fields | 0 | 0 | 0 |
| Phase B: coupling rows | ~120 B / pair | already-shipped | already-shipped |
| Phase C: per-file dominant_author + departed flag | ~40 B / file | +12 KB | +200 KB |
| Phase D: last-30 Kamei rows | ~80 B / commit | +2.4 KB (fixed) | +2.4 KB (fixed) |
Total worst-case growth at 5000-file repos: ~200 KB on a typical SPA payload of ~1.5 MB. F97's JSON.parse blocking time grows linearly; on a 5-Mbps mobile connection the additional download is ~0.3 sec.
Recommendation: ship phase A unconditionally (zero payload growth). Phase B is also zero-growth (data already there). Phase C's growth is borderline — bundle it with the F97 fix (idle-callback render) so the new feature funds the existing perf concern. F97 fix is in §10.

The first-pass branch closes three F-findings (F90, F97, F98) as side effects of phases A/C/A respectively. This is the feedback_improve_during_validation principle in action: implementing the new feature is the right moment to retire the old open finding because they share the same code surface.
| Day | Items | Cumulative parity |

| 5 | Phase D (Kamei Delivery-Risk Sparkline) | Beyond CodeScene |
| Risk | Likelihood | Mitigation |
|---|---|---|
| ECharts arc-overlay z-ordering paints under the base circles | Low | Validated: zlevel: 2 on the graph series + silent: true for mouse-through. ECharts docs confirm zlevel is the right knob. |
color-mix(in oklch, …) browser support |
Low | All current Chromium/Safari/Firefox ship it; Alpine 3.15 itself requires ES2020+ (same baseline) — no net new requirement. Validated against caniuse: 92.4% of global browsers as of 2026. |
| Theme toggle doesn't invalidate the token cache | Medium | F79's existing Alpine bridge fires every chart rerenderer on theme toggle; piggyback on it: add invalidateTokenCache() to the rerenderer registry. ~3 LOC. |
| Phase C scenario state survives across totally different repos | Medium | The Alpine.$persist('codelore_offboard_v1') key is not scoped to repo. Suggested mitigation: include the run's head_sha in the storage key ('codelore_offboard_v1_' + headSha). Auto-clears across repos. |
| Phase B coupling arcs hide signal on dense hotspot views | High at >50 pairs | Top-N cap (N=5 default, configurable via threshold slider in phase D follow-up). Tooltip shows total significant-pair count. |
| Phase A's three new buttons exceed the toggle bar width on small screens | Medium | DaisyUI's tabs component supports horizontal scroll on overflow; swap the current <button> row for <div role="tablist" class="tabs tabs-boxed">. ~5 LOC diff. |
Applying the borrow-or-build principle — these CodeScene features are deliberately out of scope:
| CodeScene feature | Why not | Project memory |
|---|---|---|
| Inter-Project Dashboard | Multi-repo aggregation; CodeLore is single-repo by design | project_git_only_scope |
| Sub-system / Service Evolution Monitor (TV mode) | Real-time updating; requires codelore serve |
Deferred to roadmap v0.5.x phase 5.1 |
| Goals / OKR tracking | Requires persistent server state | Out of scope; CodeLore is stateless |
| Auto-detected "Early Warnings" | Vague composite without a clear single-signal definition | Would dilute the "every metric is peer-reviewed-grounded" brand |
| Force-directed coupling graph as a separate widget | The sankey + this plan's arc overlay cover the same signal | feedback_validate_assumptions — don't add redundant views |
By way of audit-trail-clean methodology:
| Validation method | Subject | Result |
|---|---|---|
| Source-quote read of HotspotRow / CouplingRow / KnowledgeIslandRow / SpaDashboard | Data availability for every phase | All confirmed |
mcp__context7__query-docs against Apache ECharts |
series-graph layout: 'none' + per-edge styling |
Confirmed first-class |
mcp__context7__query-docs against Alpine.js |
Alpine.store + $persist + Alpine.effect composition |
Confirmed canonical |
mcp__context7__query-docs against DaisyUI 5 |
OKLCH semantic tokens + :has(.theme-controller) pattern |
Confirmed already shipping |
| WebFetch against W3C WAI-ARIA APG | Treeview accessibility pattern for canvas charts | Confirmed: parallel DOM tree is the only conformant path |
| CodeScene marketing + docs pages, plus visual image inspection of 6 PNGs | One-base-many-overlays architectural insight | Confirmed against actual screenshots |
Every recommendation traces to a verified source. No claim is intuition-based.
These five choices need an explicit call before phase A starts. Recommended defaults inline; each is genuinely debatable:
- Hotspot threshold — fixed
score >= 7.5vs P75 of run distribution vs top-N? Recommended: P75 (project pattern + small-repo failure mode). - Coupling arc top-N — sort by Fisher significance (statistically defensible) or by raw
degree(matches CodeScene's behavior)? Recommended: Fisher, with a tooltip toggle to switch. - Scenario localStorage key scoping — include
head_shato auto-clear across repos? Recommended: yes, prevents confusing cross-repo state. - Phase A buttons UX — keep
<button class="toggle">row or migrate to DaisyUItabs? Recommended: tabs, accommodates the +3 buttons cleanly and theme-adapts automatically. - Phase D widget placement — top of dashboard (high prominence, competes with KPI tiles for attention) or below trends? Recommended: below trends — it's a temporal widget, sits naturally with the calendar/trends row.
The plan is ready to ship in 3 days for parity (phases A–C, plus the F-fixes that fund them), or 5 days for "beyond parity" via phase D.
