T09: crystallization

Browse source 
A stable agentic realization becomes deterministic code. All four exit
criteria met; 163 tests pass.

- crystallization.py: trajectory capture, stability assessment requiring the
  same path across several runs, CrystallizedDriver, pytest codegen
- crystallized/test_grant_access.py: generated, runs with no model, carries
  its lineage in the docstring
- descendant preserves the ancestor's oracle set, agrees with it across five
  lab versions, and still catches a seeded defect
- reversibility shown both ways via new M24 (grant endpoint renamed): the
  frozen descendant fails loudly rather than searching, and the agentic
  ancestor recovers from the same mutation

F-0007 (open): the 54% cost reduction must not be quoted in support of the
thesis. The T07 runtime is token-free, so the measured saving is one page
fetch, one parse and a two-candidate scoring pass. The saving the concept
actually claims - tokens, latency, retry variance - is unmeasured. Together
with F-0005 this makes a bounded live-model experiment the highest-value next
investment.

Assertions in the generated test are imported rather than restated, so it is
not fully standalone. Deliberate: paraphrased claims would be a second
unverified statement of intent.
