- ARCHITECTURE.md: update level-0 job counts (8332 full workspace, 3314
Compiler surface, 0 errors).
- PyrochloreSidonBridge.md: point to current pyrochlore_sidon_receipt_v2.json
(S=1) and note removal of stale S=5/2 receipt.
- fiedler_non_identifiability.md: new note on Fiedler non-identifiability.
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
