openresearch e4cb242619 docs: create living targets folder for rapidly evolving goals
New folder: docs/living/ — for goals that change daily, not stable
findings (those stay in docs/research/).

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

# Milestones — Near-Term with Success Criteria
**Last updated:** 2026-07-03
## M1: 3-SAT Spectral Test [NEXT]
**Goal:** Build clause-incidence matrix for a small 3-SAT instance,
compute eigenvalue spectrum, check if satisfiability is spectrally
distinguishable.
**Success criteria:**
- Build matrix for ≥3 different 3-SAT instances (satisfiable + unsatisfiable)
- Compute eigenvalue spectra
- Report: can the spectra distinguish SAT from UNSAT?
**If YES:** First NP-complete data point for the octagon. P=NP route
strengthened. Write up as measurement.
**If NO:** Natural P≠NP witness on the canonical NP-complete problem.
The octagon has a limit. Write up as measurement.
**Estimated effort:** 2-4 hours (Python script, small instances)
## M2: cmix Weight Matrix SVD [NEXT]
**Goal:** Extract cmix's 23×461 layer-0 weight matrix, compute SVD,
check if top-5 singular values capture 95% of compression quality.
**Success criteria:**
- Modify cmix to dump weight matrix after training on enwik8
- Compute SVD (23 singular values)
- Rank-k approximation: does k=5 preserve ≥95% of compression ratio?
**If YES:** Search space reduces from 23×461 to 5D. The octagon
works for cmix (linear system, rich invariants).
**If NO:** cmix's weight structure is genuinely full-rank. No
spectral shortcut for context mixing.
**Estimated effort:** 4-8 hours (C++ modification + SVD computation)
## M3: Quandela SLOS Eigenvalue Product Verification [NEXT]
**Goal:** Verify that eigenvalue products of the Sidon crossing
matrix match the full SLOS output distribution.
**Success criteria:**
- Compute eigenvalue products for the 4-block Sidon matrix
- Compare against SLOS K=2 output
- Report: do they match?
**If YES:** SLOS shortcut confirmed for linear optical. Replace SLOS
with eigenvalue products (400x speedup on block-diagonal circuits).
**If NO:** The K=1 spectrum doesn't determine K=2 output (despite
linearity). Need to find what's missing.
**Estimated effort:** 2-4 hours (Python + Perceval)
## M4: CRT-Coprime Hachimoji Pairing Rules [FUTURE]
**Goal:** Design 8 hachimoji bases with 4 coprime pairing rules.
Verify CRT reconstruction works.
**Success criteria:**
- 4 pairing rules with gcd(L_i, L_j) = 1 for all i≠j
- Each base has a unique partner under each rule
- CRT lift reconstructs the base index from 4 residues
**If YES:** The DNA-CRT bridge is designed. Next: simulate
hybridization energy landscape.
**Estimated effort:** 4-8 hours (design + verification)
## M5: Reaction Prime Existence Proof [FUTURE]
**Goal:** Prove (or disprove) that every DNA computation factors
into reaction-primes.
**Success criteria:**
- Define the reaction algebra formally (generators, relations)
- Prove existence of factorization (or find a counterexample)
- If existence: prove uniqueness (or find non-unique factorization)
**If EXISTS + UNIQUE:** Reaction-prime framework is sound. The
conservation law = FTA for computation.
**If NON-EXISTENT or NON-UNIQUE:** The framework needs refinement.
The prime decomposition isn't universal.
**Estimated effort:** 8-16 hours (Lean formalization)
