sheet_graph
Indexes every plan-set sheet to classify roles, merge continued schedules, corroborate room numbers with names, and flag non-room tags and revisions so agents can decide what to measure.
Instructions
The plan-set INDEX (#87): every sheet's role (plan / schedule / legend / …, with confidence and the title evidence), the schedule tables found (kind, row count, region — a schedule CONTINUED across sheets ("… SCHEDULE — CONT'D") reads as ONE table, the continuation fragment naming its base in "continues"; rotated column headers are read at their quarter-turn and flagged), every number CORROBORATED as a room (with the stacked room NAME when one exists, the room's BUILDING on multi-building sets, and "corroboration" saying why it counts as a room) plus "unmatched_tags" — the numbers that are NOT rooms (keynote hexagons, detail markers, dimension fragments, legend rows), each with a reason, listed and never dropped; READ those reasons, one of them may be a room the schedule left out, the detail callouts (3/A-601 → sheet edges), the set's building designators, every REVISION marker the set carries (text markers "Δ2"/"REV 2" AND drawn deltas — a bare digit inside a triangle of linework, proven from vector geometry and flagged drawn — in "revisions", and attached to the schedule row / room tag they sit on), and named indexing gaps in "notes". Built once per document from the text layer and cached. This is how an agent decides WHAT to measure without a human enumerating the rooms: list the rooms here, resolve each with resolve_tag, then measure with measure_polygon on its wall faces. A scanned set (no text layer) returns available: false — unavailable, never half-populated. Coordinates are image px at render scale 2.0: PDF pt × 2, origin top-left, y down (the browser canvas's native space). Sheet payloads carry dims in both px and pt.

Output Schema
| Name | Required | Description | Default |
|---|---|---|---|
| notes | No | Named gaps found while indexing (e.g. a continuation whose rows could not be aligned) — the graph refuses silently dropping anything | |
| rooms | Yes | Numbers CORROBORATED as rooms — a room-finish row answers for them, or (where the set carries no room-finish schedule) a room name is drawn with them. Each says which in `corroboration`. Schedule sheets contribute rows, never phantom rooms | |
| counts | Yes | ||
| sheets | Yes | ||
| callouts | Yes | Detail callouts (3/A-601) — edges to their target sheets | |
| available | Yes | false = the set has no text layer (a scan) — the graph degrades to unavailable, never half-populates | |
| buildings | No | Every building designator the set names (sorted) — present only on multi-building-aware sets. Room numbers reused across these need qualified tags ('A-134') | |
| revisions | No | Every delta-triangle / REV-tag marker the set carries — text markers ('Δ2', 'REV 2') and DRAWN deltas (a bare digit inside a triangle of linework, drawn: true) — where one sits, the ink changed under that revision. Markers on a schedule row or room bubble also attach there (and ride resolve_tag). A revision CLOUD is arc-chain linework these detectors do not read — absence here is not absence of revisions | |
| unmatched_tags | No | Numbered tags on plan sheets that are NOT counted as rooms — keynote hexagons, detail markers, dimension fragments, legend rows. Listed with a reason, never dropped. A real finish plan is covered in 2–3 digit numbers that are not rooms; counting them as rooms makes every one come back "no schedule row", which reads exactly like the lost-bid case and buries it |
