# Audit Icon Pipeline

Detect missing glyphs, missing icons, and stale manifests by comparing registries against glyph mapping files, icon directories, and manifests. Produces a structured gap report covering skills, agents, and teams.

## When to Use

- After adding new skills, agents, or teams to check if icons are needed
- Before a full pipeline render to identify what's missing
- After registry updates to ensure manifests are in sync
- Periodic health check of the icon pipeline

## Inputs

- **Optional**: Entity type filter — `skill`, `agent`, `team`, or `all` (default: `all`)
- **Optional**: Palette to check (default: `cyberpunk` — the reference palette)

## Procedure

### Step 1: Read Registries

Collect all entity IDs from the source-of-truth registries.

1. Read `skills/_registry.yml` — extract all skill IDs across all domains
2. Read `agents/_registry.yml` — extract all agent IDs
3. Read `teams/_registry.yml` — extract all team IDs
4. Record counts: total skills, agents, teams

**Got:** Three lists of entity IDs with counts matching `total_skills`, `total_agents`, `total_teams`.

**If fail:** If a registry file is missing, report the path and skip that entity type.

### Step 2: Read Glyph Mappings

Collect all mapped entity IDs from the glyph mapping files.

1. Read `viz/R/glyphs.R` — extract all keys from `SKILL_GLYPHS` list
2. Read `viz/R/agent_glyphs.R` — extract all keys from `AGENT_GLYPHS` list
3. Read `viz/R/team_glyphs.R` — extract all keys from `TEAM_GLYPHS` list

**Got:** Three lists of mapped IDs.

**If fail:** If a glyph file is missing, report it and mark all entities of that type as unmapped.

### Step 3: Compute Missing Glyphs

Diff registry IDs against mapped IDs.

1. Missing skill glyphs: `registry_skill_ids - mapped_skill_ids`
2. Missing agent glyphs: `registry_agent_ids - mapped_agent_ids`
3. Missing team glyphs: `registry_team_ids - mapped_team_ids`

**Got:** Lists of entity IDs that exist in registries but have no glyph function mapped.

**If fail:** If diff computation fails, verify ID formats match between registry and glyph files (e.g., underscores vs hyphens).

### Step 4: Check Rendered Icons

Verify that mapped glyphs have corresponding rendered icon files.

1. For each mapped skill ID, check `viz/public/icons/<palette>/<domain>/<skillId>.webp`
2. For each mapped agent ID, check `viz/public/icons/<palette>/agents/<agentId>.webp`
3. For each mapped team ID, check `viz/public/icons/<palette>/teams/<teamId>.webp`
4. Check HD variants in `viz/public/icons-hd/` with the same structure

**Got:** Lists of entities with glyphs but missing rendered icons (standard and/or HD).

**If fail:** If the icon directory doesn't exist, the pipeline hasn't been run yet — report all as missing.

### Step 5: Check Manifest Freshness

Compare manifest counts against registry counts.

1. Read `viz/public/data/icon-manifest.json` — count entries
2. Read `viz/public/data/agent-icon-manifest.json` — count entries
3. Read `viz/public/data/team-icon-manifest.json` — count entries
4. Compare against registry totals

**Got:** Manifest counts match registry counts. Discrepancies indicate stale manifests.

**If fail:** If manifest files don't exist, the data pipeline needs to run first (`node build-data.js && node build-icon-manifest.js`).

### Step 6: Detect Orphan Icons

Walk `viz/public/icons*/` and flag WebP files whose `<palette>/<domain>/<skillId>` triple does not appear in `icon-manifest.json`.

1. Enumerate all WebP files: `find viz/public/icons* -name "*.webp"`
2. For each file, extract `<domain>/<id>` from its path
3. Check if `<domain>/<id>` has an entry in `icon-manifest.json`
4. Collect non-matching files as orphans — they exist on disk but are no longer referenced

```bash
# Quick orphan count per palette
node -e "
const fs = require('fs');
const manifest = JSON.parse(fs.readFileSync('viz/public/data/icon-manifest.json'));
const ids = new Set(manifest.map(e => e.domain + '/' + e.id));
const orphans = require('child_process')
  .execSync('find viz/public/icons -name \"*.webp\"').toString().trim().split('\n')
  .filter(p => { const parts = p.split('/'); const id = parts.slice(-2).join('/').replace('.webp',''); return !ids.has(id); });
console.log('Orphans:', orphans.length);
orphans.forEach(p => console.log(' ', p));
"
```

**Got:** Zero orphans. Any orphans indicate skills re-homed to a different domain without cleanup (18 orphans per re-homing = 9 palettes × 2 sizes).

**If fail:** Delete orphans manually — they have no corresponding manifest entry and will not be served. Re-home events are rare, so manual cleanup is acceptable.

### Step 7: Generate Gap Report

Produce a structured summary.

1. Format output as a clear table or list:
   ```text
   === Icon Pipeline Audit ===

   MISSING GLYPHS (no glyph function):
     Skills: 5 missing — [list]
     Agents: 2 missing — [list]
     Teams: 0 missing

   MISSING ICONS (glyph exists, no rendered WebP):
     Standard (512px): 3 skills, 1 agent
     HD (1024px): 8 skills, 3 agents, 1 team

   STALE MANIFESTS:
     icon-manifest.json: 320 entries vs 326 registry (stale)
     agent-icon-manifest.json: 66 entries vs 66 registry (OK)
     team-icon-manifest.json: 15 entries vs 15 registry (OK)
   ```
2. Suggest next actions based on findings

**Got:** A complete gap report with actionable next steps.

**If fail:** If all checks pass with zero gaps, report "Pipeline fully in sync" as a positive outcome.

## Validation Checklist

- [ ] All three registries read successfully
- [ ] All three glyph mapping files checked
- [ ] Icon directories scanned for both standard and HD
- [ ] Manifest freshness verified
- [ ] Orphan icons checked (disk paths vs manifest)
- [ ] Gap report produced with counts and entity lists
- [ ] Actionable next steps provided

## Pitfalls

- **ID format mismatch**: Registry uses kebab-case (`create-skill`), glyph maps may use snake_case keys — ensure comparison normalizes
- **Palette assumption**: Only checking cyberpunk palette misses palette-specific rendering gaps
- **Empty directories**: A domain directory existing but empty counts as "icons present" when globbing — check file existence, not directory existence
- **HD not rendered**: HD icons are in a separate directory tree (`icons-hd/`) — don't confuse with standard icons
- **Orphans after re-homing**: When a skill's domain changes, `build.sh` creates icons at the new path but does NOT delete the old path — always run Step 6 orphan check after any domain migration
