Documents: - README.md: rules for living docs (overwrite freely, one sentence per target, link to findings, honesty tag) - TARGETS.md: 5 active targets (invariant geometry, reaction primes, merged O(1), formal cleanup, encoder fidelity) + 3 dead + 3 candidate - PROJECT_MAP.md: what SilverSight IS right now (not what it was) - MILESTONES.md: 5 near-term milestones with success criteria (3-SAT spectral test, cmix SVD, SLOS eigenvalue products, CRT hachimoji pairing, reaction prime proof) - OPEN_QUESTIONS.md: 8 unanswered questions - DIRECTION_LOG.md: 5 direction changes from this session, with the reason for each Living docs rules: - No measurement required (goals, not findings) - Overwrite freely (git history preserves old versions) - One sentence per target - Link to docs/research/ for backing evidence - Honesty tag: MEASURED / OPEN / SPECULATIVE

Open Questions

Q1: Does 3-SAT have a spectral signature?
The first NP-complete test case for the octagon. If YES → P=NP route via spectral methods. If NO → natural P≠NP witness. [Link: OCTAGON_PRINCIPLE.md §P vs NP]
Q2: Can eigenvalue products replace SLOS for linear optical circuits?
SLOS is linear → U^(⊗m) determined by U's spectrum → eigenvalue products should determine the output. Measured K=1 failed, but FULL spectrum (all products) is untested. [Link: MERGED_O1_TRANSFORM.md §SLOS linearity]
Q3: Is the cmix weight matrix low-rank?
If the 23 singular values are dominated by top-5, the compression shape lives in 5D. The search for better compressors becomes 5D, not 23×461. [Link: cmix_epigenetic_analysis.md]
Q4: Does every DNA computation factor into reaction-primes?
The algebraic version of "is there a fundamental theorem of arithmetic for computation?" If yes → conservation law = FTA. If no → the framework needs a different algebraic structure. [Link: REACTION_PRIMES.md]
Q5: Can the three O(1) transforms merge into one physical step?
Adleman (search) + CRT lift (reconstruct) + CRT gradient (verify) as one DNA hybridization. The wall is O(n) readout. The decision-problem shortcut (1-bit answer) is the most promising escape. [Link: MERGED_O1_TRANSFORM.md]
Q6: What is the Φ-metric?
The "geometry of observability" — what defines what counts as "same object" before physics processes it. Is it a kernel? A distance? An operator-valued metric? This is the formalization gap between the vision and a computable system. [Link: INVARIANT_COMPUTATION_GEOMETRY.md]
Q7: At what n does the DNA hybridization energy gap fail?
The SNR cliff question. For the merged O(1) transform: the energy gap between correct and near-correct hybridization is constant (~1 mismatch), but the number of near-correct candidates grows with n. When does the gap become too small for thermodynamic selection? Same cliff as superposition (k=16: lossless, k=48: lost). [Link: MERGED_O1_TRANSFORM.md §The Energy Gap Problem]
Q8: Does the Sidon spectral signature generalize to other NP properties?
Sidon = pairwise-sum matrix → eigenvalue degeneracy. Does the unit-distance property have a spectral signature in the distance matrix? Does graph coloring (beyond Hoffman bound)? Does clique number (beyond Lovász theta)? [Link: OCTAGON_PRINCIPLE.md §Fast-Forward]
