resolve_tag
Resolve a room tag from a construction plan into its room-finish schedule rows and material definitions, citing every evidence pointer and flagging unresolved or ambiguous tags.
Instructions
Resolve ONE room tag across the set (#87): the plan tag → its room-finish schedule row → each finish code's definition in the finish/material schedule, EVERY edge carrying an evidence pointer (sheet + literal text + bbox — pass a bbox to view_sheet to look at the source). Rows carried by a continuation sheet ("… SCHEDULE — CONT'D") resolve exactly like base-sheet rows, citing the sheet the ink is on. The doctrine is refusal over guessing: a room that appears on the plan with no schedule row returns status "unresolved" with the reason (and still cites the plan tag); reused room numbers return "ambiguous" rather than picking one — on a multi-building set the refusal LISTS the candidate rows per building, and a building-qualified tag ("A-134") picks the building the set names. A delta triangle or REV tag on the answering row (or the plan bubble) rides the result as "revisions": the codes returned are the POST-revision answer, but the ink changed under that delta — view_sheet the marker's bbox and check the addendum before pricing. 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.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| tag | Yes | The room tag as drawn, e.g. "134" or "139A" — or building-qualified on a multi-building set, e.g. "A-134" (building A, room 134) |
Output Schema
| Name | Required | Description | Default |
|---|---|---|---|
| tag | Yes | ||
| room | Yes | The plan tag, when the room appears on a plan sheet — cited even when resolution fails. null on a multi-building ambiguity: citing one building's tag would be quietly wrong | |
| reason | No | unresolved only — WHY (no schedule row / ambiguous / no schedule found). A room that appears on the plan with no row comes back here, never as a silent omission | |
| status | Yes | ||
| sources | No | The chain: plan tag → schedule row (the row cites the sheet that CARRIES it — under a continuation that is the CONT'D sheet) | |
| building | No | resolved only — the building whose schedule row answered, when the set names buildings | |
| finishes | No | ||
| revisions | No | resolved only — delta/REV markers on the answering schedule row or the plan bubble. The finishes above are the POST-revision answer, but the ink changed: check the marker (view_sheet its bbox) and the addendum before pricing | |
| candidates | No | unresolved only — every schedule row that COULD have answered (an ambiguous multi-building tag lists one per building; qualify the tag, e.g. "A-134", to pick) |
