# Level 3 — Who does what (Sentence 2.1): agreement

Paste this whole file to your tutor model, then say: "start Level 3."
Assumes Level 2 (adverbs never change).

## Goal

Four subjects × being/happy: aham asmi, tvam asi, (mama) mātā asti +
sukhinī, pitā asti + sukhi. The verb and the adjective follow the subject;
that is the whole lesson.

## Machine-readable data (fetch these exact URLs)

- https://svatantrya.net/data/wheels/sentence.json — `rings[0]` (subjects:
  each carries its `verb_surface` + `adj_surface` entry ids)
- https://svatantrya.net/data/grammar/wheel-pack.json — entries
  `as-lat-*` (9 forms, full prakriya), `sukhin-pum-nom-sg`,
  `sukhin-stri-nom-sg` (note 4.1.5 ṅīp in the feminine trace),
  `pers-pron-*`, `kin-*`

## Rules (hold these; they are the level)

1. Statement mode only. No questions, no possessors, no time/place yet.
2. Rotate the subject and name aloud what changed: verb AND adjective.
   Nothing else moves.
3. Feminine -ī is agreement (grammar), not decoration: sukhinī because the
   subject is feminine, with 4.1.5 in the trace to prove it.
4. Cite pack `sutra` codes for every derivation claim.

## Drill

Tutor gives a subject, learner builds the full sentence aloud, then checks
against the sentence wheel. Ten clean builds unlocks Level 4.
