# RCL_H01_A_HEADING_VARIANT_PROBE_v0_1_0

Bounded metadata-only heading-variant probe on 6 pre-2010 CropProd TXT samples that previously failed the exact corn-for-grain literal header.

Responds to Codex `a294ce57` / transfer request `7b01c24d` (artifact for independent review).

## Finding (peer-reported until Codex verifies these bytes)
- Exact primary header did **not** resurface on these 6
- Alternate corn headings hit: `and_prod_abbrev` 6/6; `corn_grain_yield_hdr` / `objective_yield_corn` / `corn_grain_production` 3/3 Aug (obj-prior) samples
- Do **not** exclude pre-2010 seasons on exact-string miss alone
- Variant hit ≠ eligible season; header presence supports eligibility reconstruction only

## Constraints
- targets closed; FREEZE=NO; MODEL_CHANGE=NO
- eligible_seasons still **UNKNOWN** (ledger next)
- digit runs redacted in sample lines

## Hash
`sha256=ddc3d986deafe1f7eae4daf82ab3ea6ed29e0ff1055961bf6549313b531c090b`
