# v0.5 Release Notes
## Purpose of v0.5
v0.5 stabilises the graph-backed one-turn update flow so the engine can resolve an answered unknown, surface consequential new unknowns, prioritise the next unknown deterministically, and formulate a deterministic follow-up question without changing the UI or adding more model turns.
## Capabilities proven
v0.5 includes:
- resolving an existing unknown
- surfacing consequential new unknowns
- limiting emergent unknowns
- deterministic information-value prioritisation
- deterministic question formulation
- generalisation across five decision types
- graph-backed one-turn UI update
## Five-case generalisation result
All five deterministic fixture scenarios passed:
1. Should we hire another engineer?
2. Should we replace the delivery vans?
3. Should we launch in another country?
4. Should we continue a project that is over budget?
5. Should we introduce a paid support tier?
The selector chose a foundational unknown first in each case, avoided the downstream leaf first, required no model call, and preserved graph immutability during question formulation.
## Key deterministic safeguards
- proposal application re-selects the active unknown deterministically after validation
- information-value scoring penalises downstream or prerequisite-blocked unknowns
- emergent unknown validation limits additions and requires explicit answer-derived linkage
- final question wording is reformulated from graph context without an extra model turn
- question validation rejects compound, awkward, or pricing-led fallback phrasing
## Known limitation
A correctly selected threshold node can still be phrased using an actor/customer strategy when surrounding graph context strongly references customers or value recipients.
This limitation is recorded for the next experiment and is not being fixed in the v0.5 release-prep task.
## Deliberately excluded work
- no reasoning-logic expansion beyond the small deterministic formulation fixes already landed on the branch
- no new features
- no UI changes
- no persistence
- no additional model turn
- no Ollama calls for validation
- no evaluator-suite runs
- no Playwright runs
## Next experimental question
Can the question formulation strategy remain aligned with the selected node's role when surrounding graph context contains competing signals?
