# Batch 206 - construction consolidation after Rule 163

## Setup

- Starting verified total: 10,347 / 20,000.
- Previous completed batch: Batch 205 / Rule 163.
- Proposed rule: Rule 164 - construction consolidation after Rule 163.
- Batch target: 50 hand-authored Kuku Yalanji synthetic sentences.

## Source Pass

Rule 164 retains the ten plant/tree reference heads admitted in Rule 163:

- `buyukal` - tree, English name unknown.
- `dalkan` - casuarina pine / beach tree.
- `dari` - boxwood tree.
- `dibul` - cane.
- `dilbal` - hickory tree.
- `dili` - corkwood pine.
- `jabarr` - baldy gum tree.
- `jakari` - spiderlily.
- `jama` - a type of tree.
- `jilbar` - corkwood tree.

Dictionary exact readback confirmed all ten target heads. Patz grammar readback confirmed supporting forms:
bare `dili` and `dili-mba` in the noun case table, `dalkan-ba` as a casuarina-pine source form, `yaluy`
and `yinyay` local demonstratives, `nyaji-l` as see/hear/perceive, `nyaji-ny` past, and bare nominative
pronouns `ngayu`, `yundu`, `jana`, and `ngana`.

## Scope

Rule 164 is a construction consolidation pass, not a lexical expansion. It reuses the same ten targets and
rotates the deictic/perception support frames:

- Rows 1-10: bare `yinyay` deictic identification.
- Rows 11-20: `ngayu` present perception with `yaluy`.
- Rows 21-30: `yundu` present perception with `yaluy`.
- Rows 31-40: `jana` past perception with `yaluy`.
- Rows 41-50: `ngana` present perception with `yinyay`.

Closed traps remain closed: eating, fruit-gathering, medicine, bark use, burning, weaving, tying, spear-making,
timber/material-source, storm-control, place-name, target case, target compound, possession, and ecological-event
semantics.
