feat(lean,infra): Corpus278→250 rename + SLOS-calibrated braid defaults
...
- Renamed Corpus278/Matrices278 to Corpus250/Matrices250 across all
Lean modules, Python shims, JSON schemas, and documentation
- Applied SLOS-calibrated defaults to braid_search.py:
bracket_cost base=8x/16x, crossing_penalty gap_reward=0.01
- Synced same defaults to research-compute-fabric submodule
- Updated Burgers 0D defaults: nu=0.9995, advection=0.075
- Fixed 278→250 refs in pist_predictions JSON (claim_boundary, total)
- Fixed stale schema refs in .devin/skills/lean-proof/SKILL.md
- Updated AGENTS.md build baselines to post-clean counts (3314 jobs)
- Updated lake-manifest.json sparkle rev to match lakefile.toml
- Fixed Q16_16 signed conversion bug in qaoa_adapter tunable costs
- NBody.lean: pre-existing dirty changes (introN failures, NOT our work)
Build: 3314 jobs, 0 errors (lake build Compiler)

fix(lean): complete projectionOrdering proof in GeometricCompressionWorkspace
...
Replace the TODO(lean-port) sorry with a complete proof of the
projectionOrdering theorem: for positive SourceValue pairs s1 < s2
with s2 ≤ maxExpected, projectToCoding preserves strict ordering
of the Q0_64 values.
The proof uses Nat-only arithmetic (no Float) and handles two cases:
- a2 < d: both values fit in Q0_64 range, ordering follows from
monotonicity of integer division
- a2 = d: a2*s/d = s clamped to q0_64MaxRaw; a1*s/d < q0_64MaxRaw
via the key inequality (d-1)*s < (s-1)*d

feat(lean): complete goldenContractionEnergyDecrease proof + PIST predictions pipeline v2
...
- PistSimulation.lean: proven goldenContractionEnergyDecrease (no sorry)
7 supporting lemmas, h_u'_nonneg + h_pt hypothesis, fold induction
- Connectors.lean: restored zeroIsVoid theorem with Q16_16 proof
- CanonSerialization.lean: removed dead theorem, documented blocker
- FixedPointBridge.lean: eliminated Float from compute paths
PIST predictions pipeline:
- pist_matrix_builder.py: reproducible matrix-only builder (SHA256)
- build_pist_matrices_278.py: generates PIST/Matrices278.lean
- PIST/Classify.lean: classifyProxy/classifyExact stubs (v2 surface)
- PIST/Matrices278.lean: 250-entry matrix HashMap
- build_corpus278.py: reads predictions artifact, uses classify*
- Pipeline contract documented in root AGENTS.md
Cleanup:
- Archived 5 orphan pist_* shims, 5 old route_repair variants
- Quarantined PIST/Repair.lean (no external callers)
- Created 4 opencode agents for remaining TODO items
Build: PistSimulation 3309, Compiler 3313, Full 3571 (0 errors)
