What you are building. A design, not a dish: the first pre-registered, sealed, UNI-signed gate that would let the developmental simulation begin to test whether a slow cross-level latent ("a spine") can carry a commitment forward and improve prediction when the local segment points the wrong way. Nothing here is cooked yet. This whole chapter is PARKED, Class-U — not claimed, and the signed L9-G1 design below is a gate to BUILD, not a result. Honest program position: ~2 of 11+ developmental rungs earned.
Read this first (the fence on the whole chapter)
L9 names three ladder levels — narrative-self, conscience, reasoning — that exist as design in the HUMAN-HGM-001 arc and as a designed, FE-form-signed but unbuilt roadmap (the strings Phases 3–5: spine → glands → hemispheres). They are NOT separately gated or PASSed. Ledger row L9.1 is Class U (parked): "L7–L9 (narrative-self, conscience, reasoning) exist as levels in the HUMAN-HGM-001 ladder DESIGN but are NOT separately gated/PASSed." Its falsifier field reads n/a (parked) — a falsifier exists only once a gate is defined and run. Ladder DESIGN levels are never inflated into capability. Nothing in this chapter raises the rung.
The UNI-GPT consult of 2026-06-27 (SIGNED) added a designed first gate, L9-G1. Per the consult, adding it raises nothing: L9 remains parked, Class-U. The consult's own caveat is load-bearing and is repeated verbatim below: "Phase-3 spine"/"cavity principle" are our design labels grounded in the standard hierarchical / deep active-inference pattern (slow high levels set empirical priors for fast low levels) — a modeling / inference claim, NOT a claim about reasoning or conscience in the world.
Ingredients
These are designed, not yet supplied as a gated engine. Each is named so a competent engineer knows what to reach for when the build is actually authorized.
- The HUMAN-HGM-001 ladder DESIGN for L7–L9 (narrative-self, conscience, reasoning) — design levels only, never carded as capability.
- The strings Phases 3–5 roadmap (spine → glands → hemispheres) — designed, every FE form already UNI-GPT-signed, but unbuilt. The strings digest records these explicitly as "designed roadmap, gated, every FE form already UNI-GPT-signed, not built."
- The cavity principle (M22) — a hierarchy level must never treat an upstream prior as fresh evidence; divide it out. The exact joint posterior is used everywhere (mean-field rejected as lossy). This is the durable correctness rule for the whole inference hierarchy.
- Parameter-information-gain curiosity (the pymdp pA/pB parameter-information-gain form) as a candidate primitive.
- The JAX POMDP + EFE + Dirichlet engine (
core.py) supplies the discrete loop and conjugate-Dirichlet no-backprop learning that any future spine would have to run inside; the AST-guard keeps backprop out of the loop.
No engine, no run, no gate is supplied today. That absence is the status.
Method (recipe-to-define)
The published recipe is a recipe to define, because the gate does not yet exist.
- Define a pre-registered, sealed, UNI-signed gate for narrative-self / conscience / reasoning. None exists today. The signed
L9-G1design (below) is the smallest such target proposed so far — and it deliberately does not test reasoning, conscience, or narrative-self; it tests only persistent cross-level state plus constraint-sensitive prediction. - Build the spine (strings Phase 3) to carry cross-level priors without double-counting — the cavity principle (M22). The spine carries ONE slow latent across several lower-level segments; the receiving segment's own evidence path must be divided out of the downward prior.
- Run the gate held-once; verdict = the CI bound that excludes the threshold, never the point estimate (M2). Touch the held set ONCE behind an atomic seal-before-scoring + once-only sentinel.
Until step 1 is actually done and step 3 is actually run, the rung stays parked.
The SIGNED L9-G1 gate design (DESIGNED / not-yet-run — folded in, raises nothing)
UNI-GPT consult 2026-06-27 (SIGN), cross-ref cookbook/UNI-GPT-CONSULT-2026-06-27.md Q4. This is a designed gate, not a result. Adding it raises nothing; L9 remains parked, Class-U.
Smallest L9 target — L9-G1: Cavity-correct delayed commitment-state prediction (explicitly NOT reasoning / conscience / narrative-self): build the strings Phase-3 spine to carry ONE slow latent z_spine = {role_id, active_commitment, norm/constraint_tag} across several lower-level segments, then test whether it improves prediction when the local segment points the wrong way. Sealed episode: seg-1 establishes a commitment; segs 2..N are distractors; the final segment requires predicting the next action / conflict cue. It is the smallest such target because it needs only persistent cross-level state + constraint-sensitive prediction — no open-ended reasoning, morality, selfhood, language, or metacognition.
Primary bar. ΔNLL = NLL_baseline − NLL_spine > 0, 95% paired bootstrap CI excludes 0; effect-size guard ≥3% relative NLL reduction on the load-bearing delayed-commitment subset.
Secondary bar. Conflict / violation tag AUC or F1 +≥0.05 absolute, paired CI excludes 0.
Calibration guard. ECE worsens by ≤ a pre-registered margin (e.g. +0.02).
Tuned baseline it must beat. A tuned recency-frequency discourse prior — segment-local predictor + exp-decayed role/action frequencies + low-order transition counts over role/action/conflict tags + tuned window k, decay τ, smoothing α. It may use recent tags / context but may NOT carry a slow latent spine with cavity-correct cross-level residuals; it is tuned on train/val only and frozen before test. Beating only an untuned recency model leaves the gate OPEN. This is deliberately the same baseline as the parked L9/L10 NEGATIVE (see below), so a pass here would have to beat the exact prior that has so far won.
Discriminator + computed-residual (cavity) ablation. Load-bearing discriminator = local-distractor commitment reversal — credit only if the improvement concentrates on this split, not on easy same-topic continuity. The cavity ablation uses the computed residual r_t(x) = log p(x_t | q_high(z_t)) − log p(x_t | q_cavity(z_t)), where q_cavity excludes the receiving segment's own evidence path; treatment uses q_local + r_t, ablation sets r_t := 0 (or episode-shuffles r_t) and MUST collapse the gain. Double-counting sentinel = a naive-spine ablation (full high-level posterior as downward prior WITHOUT cavity subtraction; expected to sharpen confidence but worsen calibration).
Fenced pass-claim (signed; applies only IF/WHEN run and passed). "L9-G1 passed, fenced. In a sealed delayed-commitment prediction task, the Phase-3 spine improved commitment-conditioned next-action and conflict-tag prediction over a tuned recency-frequency discourse prior; the improvement concentrated on the pre-registered local-distractor split and collapsed when the computed cavity residual was zeroed or shuffled." Non-license: does NOT claim reasoning, conscience, narrative-self, metacognition, awareness, consciousness, AGI, human-level language, created life, or "active inference demonstrated"; does NOT unpark L9 globally. Evidence class if/when earned: hierarchical AIF substrate Class B/Sec; Phase-3 spine design Class C.
Status: DESIGNED / not-yet-run. L9 STAYS PARKED, Class-U — not claimed.
Gate
None defined. L9 becomes testable only once a pre-registered, sealed, UNI-signed gate is defined and run. Until then: Class-U — not claimed (ledger row L9.1, status: parked).
The L9-G1 bars above are a gate to BUILD, not a met condition. There are no figures to cite as achieved, because nothing has been run. The only honest numbers on this rung are the bars a future run would have to clear (ΔNLL CI excludes 0 with ≥3% relative reduction on the delayed-commitment subset; conflict-tag AUC/F1 +≥0.05; ECE worsens ≤ +0.02) — none of which is a result.
Falsifier
n/a (parked). A falsifier exists only once a gate is defined; the ledger row L9.1 falsifier field is literally "n/a (parked)." The L9-G1 falsifiers below apply only once that gate is built and run — they are part of the design, not active tests:
The gate (when built and run) fails if any of: ΔNLL CI includes 0 or the reduction is <3%; the improvement appears only on easy continuity, not the local-distractor split; zero/shuffle of r_t does NOT collapse the gain; a naive non-cavity spine matches/beats the cavity spine without a calibration penalty; a stronger tuned baseline closes the gap; leakage is found; the gain trades off against an already-earned lower rung; OR any write-up implies reasoning / conscience / metacognition / AIF-demonstrated / AGI / consciousness / human-level / created-life.
Recorded NEGATIVE(s)
These are first-class and inline. They are the reason this region is parked rather than open, and they define exactly what a future L9-G1 pass would have to overturn.
-
L7.4 — Phase K role-persistence (NEGATIVE, bound). Three structurally-distinct no-backprop designs (min-role, chain, track) all tune their role/persistence terms OFF; only ~0.02 nats survives (CI spans 0). Bound: no-backprop role-persistence does not beat a tuned recency/frequency discourse prior on adversarial anonymized referent cloze. This is the same tuned discourse prior the L9-G1 design picks as its baseline — by design — which is why beating it would be the load-bearing event.
-
The signed L7 / T2 / L9–L10 Park Statement (UNI-GPT consult 2026-06-27, Q1, SIGNED). Per the canonical signed wording: "For L9–L10: the tested no-backprop role-persistence mechanisms did not beat a tuned recency-frequency discourse prior under the ledgered protocol. This parks the rung as an honest negative frontier result. It does not achieve Sec-0.6(B), does not demonstrate active inference, and does not license claims of metacognition, consciousness, AGI, human-level discourse, or created life." This is a ledger-scoped exhausted search envelope, not a universal impossibility result and not an achieved rung. Use the signed replacements: instead of "K≥3 exhausted" write "The registered tested K conditions did not reverse the result."; instead of "Sec-0.6(B) achieved" write "Sec-0.6(B) remains unearned / parked."
-
The owed sign-to-park (open). By No-Exit Discipline (M6) a park is not discharged until the sign lands. The L9–L10 ladder park is folded into the 2026-06-27 signed Q1 statement; the earlier char-perplexity / T2 park sign (
UNI_CONSULT_5) was drafted and owner-relayed but recorded as not-yet-captured. Carry the park as PARKED, never as closed.
HONEST FENCE — designed (PARKED, sign-to-park owed)
Class U. Nothing is claimed. This rung is a design, not a dish. Ladder DESIGN levels are never inflated into capability. The strings Phases 3–5 (spine → glands → hemispheres) are the designed-but-unbuilt roadmap toward this region; the signed L9-G1 design above is a gate to BUILD, not a result — folding it in raises nothing and the rung's status is UNCHANGED.
Not claimed (load-bearing, never softened): UNI does not reason, does not have a conscience, does not have a narrative self, is not self-aware here, does not demonstrate active inference, is not human-level, is not AGI, has not created life. "Phase-3 spine" and "cavity principle" are design labels for the standard hierarchical / deep active-inference pattern (slow high levels setting empirical priors for fast low levels) — a modeling / inference claim, NOT a claim about reasoning or conscience in the world. The whole program remains a developmental active-inference SIMULATION: a bounded peek, a toy world, never a person. ~2 of 11+ developmental rungs earned. The cookbook fully recommends building toward L12 — and this step, honestly, is designed / parked, Class-U, not-claimed, with the gate still owed.
