Experimental tutorial · P8
Context pack,
one variable at a time.
p8_context_pack reuses a compatible P0 index and changes only the number of retrieved evidence chunks packed into generation context.
P0 → P8Single-variable experiment
Smaller evidence pack
What changes
Only evidence count.
P8 passes at most three retrieved evidence chunks to generation while P0 passes at most five.
What is inherited
The P0 index facts.
No duplicate indexing occurs. Durable audit fields record P0-index reuse and the exact Context Pack settings.
What is disabled
No hidden defaults.
Evaluator v5 removes pipeline, cache and routing, and keeps rewrite, HyDE, graph ingestion and RAPTOR off.
When comparison is valid
Only direct P0 → P8.
The API requires a compatible evaluator-v5 P0 parent, the same knowledge base and frozen evaluation inputs.
Reproduce it
Run the controlled walkthrough.
The real browser regression starts PostgreSQL, Qdrant, migrations, API, Console, and a controlled immutable Pack. It runs P0 then P8 and verifies Context Pack audit facts, P0-index reuse and a comparable result.
