# CNAS Phase 2 — Layout B parser handoff

State at 2026-05-11 (after C4 partial fix):
- 14 PDFs were stuck at `parse_status='no_table'`.
- Commit `bfa0b69` relaxed the `nr_crt` regex from `\s{2,}` to `\s+` (guarded
  by a Romanian capital letter). This recovers ~3-5 of the 14 PDFs that use
  Layout A (numbered rows).
- The remaining ~9-11 PDFs use **Layout B** (judet-grouped, no row numbers)
  and need a separate parser path that this handoff describes.

Key signals:
- Single-word ALL-CAPS judet on its own line (left-aligned, ~4-12 chars).
- Provider rows are indented to a fixed column (~20 chars left margin).
- Multi-line addresses with continuation rows.
- Trailing DA/NU columns indicate which test panel / service the furnizor
  is contracted for (varies by PDF type — sometimes 1 column, sometimes 7+).

## Recommended approach (~3-5h)

1. **Add a 2nd parser** `parseProviderTextJudetGrouped(text, hints)` invoked
   only when `parseProviderText` returns 0 rows AND `tip_serviciu IN
   ('oncologie','testare_genetica','radioterapie','pns','medicina_familie')`.
2. **State machine**: track `currentJudet`; when a line matches
   `^\s+([A-ZĂÂÎȘȚ]{3,15})\s*$` (also accept variants like `BUCUREŞTI` /
   `BUCURESTI`), update `currentJudet`. When the next line is indented and
   non-empty, treat it as the start of a row.
3. **Row assembly**: gather lines until next judet header, next blank-line
   block, or next provider name (heuristic: line starts with capital +
   doesn't start with `Str.` / `Mun.` / `sector` / `nr.` / city name).
4. **Column extraction**: split by `\s{3,}` like the existing parser, but
   know that col 0 = name, col 1 = address, col 2 = email, col 3 = phone,
   cols 4+ = DA/NU flags. Capture flags into a `specialitate` JSON field
   (would need a schema migration if we want to keep them structured) or
   collapse into a comma-separated text in `specialitate`.
5. **Judet override**: when judet is detected from PDF body, override the
   filename-derived judet in cnas.furnizori per-row.

## Schema-change consideration

To preserve the DA/NU flag matrix, add a `specialitate_jsonb` column to
`cnas.furnizori` (or reuse the existing `specialitate` text column with a
serialized string like `"panel_1:DA,panel_2:DA,panel_3:NU"`). Existing
column suffices for v1 if we encode as text.

## Testing

Cache the 9-11 PDFs locally (`/tmp/cnas-pdfs/`) and run the parser
unit-style. For each PDF, the expected row count is roughly the number of
`@gmail|yahoo|ro|com` email-pattern hits in the body (15-50 per PDF on
average → estimated total: 200-500 additional providers).

## Defer reason

3-5h of work for an estimated 200-500 rows (~10% of current cnas.furnizori
size, which is 36k). Lower ROI than the WSP timezone fix
(restores daily cron entirely) or ANRE electricieni (zero → ~101k rows).
