- keep adding small sourced personality batches, especially the legacy `R2D2`, `sun`, `space`, `kids`, and charm prompts
- keep adding 1-3 persona prompts per pass with tests
- prefer source-backed MIM imports when the legacy text is available, and use a temporary runtime reply only when needed to unblock user value
- Mood follow-up work in flight:
- source-backed happy/sad/angry response packs are now part of Build B
- small-talk aliases like `what are you up to` and `how are things` now stay on the emotion-query path
- Next queued persona surfaces:
- richer identity follow-ups like `who is this`, `do you know me`, `do you remember me`, and `can you recognize me`
- mood and affect prompts like `how are you`, `are you happy`, `are you sad`, and `are you angry`
- self-description charm like `what's your name`, `do you have a nickname`, and `do you like being Jibo`
- additional legacy source-backed `RI_USR` prompts where the text is short and the behavior is easy to verify
- Exit criteria:
- a stable checklist exists for the original persona surface
- each pass can be scoped to a small batch of prompts

- the next source-backed batch now includes `favorite flower`, `R2D2`, `sun`, `space`, `kids`, plus a couple of charm prompts like `can you laugh` and `can you dance`
- the follow-up mood batch now includes `how are things`, `how is your day`, `are you sad`, and `are you angry`
- the personality follow-up batch now includes `what are you up to` and `what are you doing` so small talk stays warm and local instead of falling into generic chat
- this pass keeps Build B moving while still favoring source-backed phrasing and preserving the command-vs-question boundary
- the next passes should keep the same pattern and prefer source-backed phrasing whenever the legacy MIM text is available
- if a source-backed legacy line is missing, use a temporary direct reply only to keep the pass moving, then backfill source text later
- after the favorites batch, the next doc pass should focus on richer persona follow-ups and the remaining memory/presence charm surfaces

- prioritize small source-backed slices from Pegasus/JiboOS that can be shipped safely
- keep Nimbus and stock payload compatibility as the release guardrail
- avoid broad subsystem rewrites without tests and live-capture evidence
- keep the legacy prompt inventory visible in the backlog so porting stays paced and traceable

This folder holds the next small import batch of legacy Jibo scripted-response MIMs.
The batch is intentionally narrow so we can keep expanding personality without widening the turn-state surface faster than we can test it.
It now includes a small emotion-response pack for `happy`, `sad`, and `angry` follow-up questions so the mood path can stay source-backed too.
