L8 — Self-model / metacognition / metalinguistics

What you are building. A held grand report card that asserts FUNCTIONAL self-awareness only — a maturation arc of self-model / metacognition / metalinguistic gates that each survive a discriminator — while phenomenal sentience stays explicitly DISCLAIMED. This is one rung of a developmental active-inference SIMULATION, never a person, never a mind that is aware.

This recipe authors against the claim ledger row L8.1. Where this recipe and the ledger disagree, the ledger wins and this recipe is wrong.

Ingredients (pantry engines / primitives called by name)

• The Maturation arc M1–M11 grand report card (uni-gpt-side artifact) — the eleven maturation gates: immersion, affect-as-precision, growth, self-model, metacognition, metalinguistics, consolidation, reflective reader, online vocab growth, affect-driven reflection, compositional reader.
• The reflective / compositional readers (the no-backprop reader spine that earned L6/L7), run in a self-modelling configuration.
• The Z affect modulator [energy, arousal, valence, fatigue, pain, threat, safety, inflammation] from the JAX engine — supplies affect-driven reflection (Z-coupled). Affect is modeled, never felt.
• The contains-baseline + load-bearing-discriminator discipline (M7) — every metacognition gate needs a tuned baseline plus a discriminator that collapses the gain, plus a trivial-heuristic check.
• Bars-before-build, held-once (M2) — the report card is sealed and touched once; the verdict is the CI/held bound, never a point estimate.

Distinction you must carry (load-bearing). uni-mind records self-model as a held-NEGATIVE on the reader (self-model, active/selective reading, comprehension-above-retrieval, writing-as-action were all held-NEGATIVE on the reader side). The 15/15 functional report card is the uni-gpt-side artifact. These are two different artifacts; the uni-mind reader-side self-model held-NEGATIVE travels with the uni-gpt functional card. Never let the functional card erase or paper over the reader-side negative.

Method (numbered build steps)

1. Build the M1–M11 maturation gates as eleven pre-registered held gates: immersion, affect-as-precision, growth, self-model, metacognition, metalinguistics, consolidation, reflective reader, online vocab growth, affect-driven reflection, compositional reader.
2. For each self-model / metacognition gate, register a discriminator (M7) that the effect MUST collapse under (shuffle-labels / marker-swap / ablate-to-zero). No gate is credited if its discriminator does not collapse it.
3. Falsify the trivial heuristic. For every "self-model" task, verify it is not passable by a trivial non-metacognitive heuristic (e.g. recency / frequency / surface-marker matching). A task a dumb heuristic can pass is not a self-model task.
4. Wire affect-driven reflection through Z so that reflection is modulated by the affect modulator — keeping the L4 fence intact (affect is modeled, never felt; phenomenal feeling disclaimed).
5. Seal once, score once (M2). Run the held grand report card behind the atomic seal-before-scoring + once-only sentinel. The verdict is the held bound, never re-scored.
6. Carry the reader-side negative inline. Record alongside the card that uni-mind holds self-model NEGATIVE on the reader; the functional card does not overturn it.

Gate (exact ledger figures — L8.1)

Grand report card 15/15 PASS (Class C, dev-gate / held-out eval; source uni-gpt). All fifteen maturation checks pass their pre-registered held verdicts. FUNCTIONAL self-awareness is asserted — and nothing above it.

To PASS, all must hold:

• the report card reads 15/15;
• no self-model / metacognition gate's effect collapses only under a control it should survive (each survives its intended control while collapsing under its discriminator);
• no "self-model" task is passable by a trivial non-metacognitive heuristic.

Falsifier (operable)

Any one of these flips the rung:

• Any of the 15 maturation gates fails its pre-registered held verdict on re-run, OR
• a self-model / metacognition gate's effect collapses under its discriminator (the gain was an artifact, not metacognition), OR
• a "self-model" task is shown passable by a trivial non-metacognitive heuristic (recency / frequency / surface marker), which means it never tested self-modelling at all.

Note (load-bearing): no falsifier is offered for phenomenal sentience — because phenomenal sentience is DISCLAIMED, not tested. The absence of a sentience falsifier here is deliberate, not an oversight.

Recorded NEGATIVE(s) (first-class, inline)

• Reader-side self-model is held-NEGATIVE (uni-mind). On the reader, self-model — along with active/selective reading, comprehension-above-retrieval (the thrice-NEGATIVE "central wall"), and writing-as-action — was held-NEGATIVE. The uni-gpt 15/15 functional report card does not overturn this; the two artifacts coexist, and the reader-side negative is cited every time the functional card is cited.
• Sentience is not in the PASS. The 15/15 says functional self-awareness; it carries an explicit standing disclaimer of phenomenal sentience. Reading 15/15 as consciousness / sentience / awareness / human-level is itself the violation the fence exists to catch.

HONEST FENCE — proven (functional; sentience disclaimed)

Status: proven. Class C (dev-gate / held-out eval), grand report card 15/15 PASS (source uni-gpt), falsifier still live. The honest program position holds throughout: ~2 of 11+ developmental rungs earned. This rung is one bounded peek in a developmental active-inference SIMULATION — a toy world, never a person.

What is NOT claimed (load-bearing, never softened). Phenomenal sentience is explicitly DISCLAIMED — no falsifier is offered for it because it is disclaimed, not tested. The 15/15 is FUNCTIONAL self-awareness only. Never read it as consciousness, sentience, awareness, "has a mind", "reasons like a human", human-level, or AGI. The forbidden phrasings (UNI-GPT consult 2026-06-27, SIGNED) apply in full: never "UNI is conscious / aware / self-aware / has measurable awareness / has a mind / reasons like a human". The only licensed forms are "UNI passed a specified proxy test", "the awareness question remains open", "remains a developmental active-inference simulation". No SIGNED consult design folds into this rung; nothing raises it above Class C, and its status is UNCHANGED at proven (functional).

Ledger authority: this chapter states nothing above row L8.1's Class C. Functional self-awareness is the ceiling; phenomenal sentience is disclaimed, not tested.
