API Matrix
Per-API summary: endpoints accessible, OK count, total files cached. Click an API row to drill into its endpoints.
| API | Endpoints | OK Endpoints | OK % | Total Files |

Endpoint Detail
Every endpoint × universe coverage % × field count × status. Click "Show fields" to see all captured columns/dimensions.
Universe Coverage % = files / 1937 (raw Master Universe). Available Coverage % = files / realistic-max for that endpoint (e.g. SEC EDGAR ceiling = 1686 tickers with CIK; Wikipedia = 1414 tickers with public page). Status uses Available Coverage % for fairer assessment.
| API | Endpoint | Kind | Files | Universe % | Max Possible | Available % | Fields | Status | Sample Fields |

Ticker Drill-down
Pick a ticker to see its coverage across every API + endpoint + field count.
| Ticker | Tier | Sector | Endpoints With Data | Total Per-Ticker Endpoints | Coverage % | Drill |

Field / Dimension Audit
Per-endpoint inventory of captured fields/columns. Identify lost dimensions (e.g. missing time column, missing sentiment, etc.).
| API | Endpoint | Total Fields | Avg Fields/File | Min | Max | All Captured Fields |

Full Catalog (canonical from API_ENDPOINT_INVENTORY.md)
EVERY endpoint we know about across all APIs — accessible+cached, accessible-not-yet-cached, tier-blocked (403), does-not-exist (404). Source per CHECKLIST #77: the inventory doc is the canonical catalog; filesystem walk is supplementary.
| API | Endpoint | Tier Status | Cached? | Bucket | Sample Fields | Action |

API / Endpoint / Field Usage / Stage Mapping
One row per (API, Endpoint, Field). Shows: use-case, stage, criticality, plus Coding Status (referenced in backtest/ or scripts/) and Wiring Status (referenced in active code path: backtest/data + engine + signals + results).
| API | Endpoint | Field | Use case | Stage | Criticality | Coding | Wiring | Refs |

Coverage Matrix - per-(API, endpoint, field)
Owner directive 2026-05-09: per-field coverage with commentary on every <100% row, plus pyramid status badges (cached / coded / wired / tested) per endpoint. Endpoint-summary rows shown in bold.
Coverage % semantics by Kind (per CHECKLIST methodology rule v8h+1 2026-05-10): per_ticker = % universe tickers with non-null; single = % rows with non-null in this column (data-quality); global = % series files with non-null observation in this column. The Completeness column shows the kind-appropriate freshness signal: row-count + latest-obs-date for single feeds; series-count + non-empty% + latest-obs-date for global feeds.
| API | Endpoint | Field | Kind | Coverage % | Completeness | Commentary | Cached | Coded | Wired | Tested | Files |
