Finding #20 (Super-Blueprint §3.2). surprise_residual was Euclidean Gram-Schmidt
on flat 32-coefficient vectors — metric-blind (it ignored the (+,+,+,+,-)
signature and the blade grade structure), so "inside the admissible span" was
judged by the wrong geometry.
Operator math (core/physics/surprise.py):
- Exact metric-orthogonal projection: solve the normal equations G c = r
(G_ij = cga_inner(b_i,b_j), r_i = cga_inner(b_i,x)) via lstsq, under cga_inner
(32-vec) / eta (5-vec).
- Fail-closed (typed SurpriseResidualError) on a metric-degenerate span, keyed on
rank(G) < rank(B) — a null direction with no reciprocal (lone n_o). Refines the
literal "rank(G) < k": mere linear dependence among non-null columns is admitted
(lstsq projects onto the span), so a redundant live basis [1, source] and the
non-degenerate pair {n_o, n_inf} are admitted; only a lone n_o is refused. The
disclosure names the Gram null-space direction (not just zero-diagonal columns).
- Reconciled productivity polarity: productive_transfer = low Procrustes AND low
surprise (was `sur_norm >= 0.0`, always true). High surprise routes to discovery
(split follow-up). Corrects the ledger's transfer/discovery conflation.
Adversarial verification (3 independent lenses) found, and this fixes:
- HIGH soundness hole: sur_norm was the reversion pseudo-norm, which VANISHES on
a nonzero metric-null residual (the n_o/n_inf light cone) -> false-zero surprise
-> an out-of-span light-cone probe was wrongly admitted as in-span. Now the
DEFINITE (Euclidean) norm of the residual: the projection stays metric-exact,
the magnitude is 0 iff nothing is unexplained.
- HIGH regression: the analogical-transfer harness called surprise_residual
OUTSIDE its try/except, so a degenerate source crashed the whole run. Now
guarded: records a refused case and continues.
- grade-support `allowed` -> exact-nonzero (removes a spurious-leak edge under
coefficient amplification of sub-tolerance grade dust).
DiscoveryCandidate wiring into the contemplation loop is split to its own
follow-up (a distinct cross-cutting surface). Off-serving (nothing in
serving/runtime imports core.physics.*). Tests: 15 behavioral tests
(metric-vs-Euclidean divergence, null-cone regression, null refusal +
combination-degenerate disclosure, 5-vector branch, polarity); 139-test physics
sweep green; ruff clean.
The Super-Blueprint §3.3 "grade-5 pseudoscalar alignment anchor" is
mathematically vacuous in odd-dimensional Cl(4,1) and cannot be built as
specified (3-agent R&D convergence — Opus/Grok/Terra — ratified):
- I₅ is central in odd dim → V·I₅·Ṽ = ±I₅ for every versor; orientation is
invariant by construction (nothing to block).
- Field-state versors are even → F[31] ≡ 0; the gated ⟨F·F̃⟩₅ = 0 for the
source and target of every transition. The gate compares 0 == 0.
- The "even-versor parity gate" repair is equally vacuous (even subalgebra is
closed under the sandwich; odd-grade mass ≡ 0 on the sanctioned path).
Removes the namesake rather than leaving it masking an absence:
- Delete _PSEUDOSCALAR_IDX + all F[31] reads (dead `ps` history element and
CoherenceResidual.pseudoscalar — both structural zeros).
- Rename telemetry channel pseudoscalar_floor → autonomy_floor (it was always
self.floor, the earned-autonomy ceiling).
- Bump telemetry schema goldtether_coherence_v1 → v2 (shape changed).
The integrity-anchor role is subsumed by versor closure + GoldTether harmonized
residual (#24) + biography/identity holonomy. Ledger §5 rewritten with the
vacuity proof, subsumption, and the reusable "would this gate ever fire on the
sanctioned construction path?" meta-criterion.
No serving/runtime path touched (core.physics.* is off-serving). Tests: 33 pass
/ 1 xfail (Cartan #2) across goldtether + fidelity + miner + transfer suites;
ruff clean.
