## Piano 66 — Esplorare il confine: 8 domini GUE, 5 Poisson — il confine è il terzo incluso operativo

## Tensioni attive

## Pattern di formulazione emersi (vincoli, non tensioni)
Pattern che il falsifier ha imposto in 2+ cicli. Applicali quando scrivi il report. NON sono nuove tensioni da esplorare — sono regole sul COME formulare i claim del cycle che stai facendo.
- 29 04 perimetro p5
- 30 04 drift monotonia

## Convergenza — dove più tensioni puntano allo stesso punto
  "trascendenza" → TRASCENDENZA_LIMITE, G_POTENZIALE_NULLA
  "confine" → TRASCENDENZA_LIMITE, BOUNDARY
  "nelle" → TRASCENDENZA_LIMITE, PIANO_PRIMARIO_DUE_ASSIOMI
  "producono" → TENSIONE_ENTITA, DUALITA_DIPOLARE_VS_ILLUSORIA
  "tutto" → G_POTENZIALE_NULLA, TENSIONE_ENTITA
Questo è dove il potenziale si concentra. Non ignorarlo.

## Ultimi 3 run — da dove parti
### Agent Report — Perturbation Dimensionality Is Not Yet a Stable GUE Invariant
Trovato: 1. **The strong GUE second-axis claim does not survive as stated.** Under direct `scale_0330` observables, long independent GUE replicates give rank 1.381 ± 0.223 and PC2 9.9% ± 6.9%, not rank 1.889 and PC2 25.2%. The previous number is inside the fragile short-sample regime: GUE short controls have
Verdetto: **CONSTRAINT on META + BOUNDARY**: "GUE has a second perturbation axis" must be scoped to the exact sample length, generator, and observable definitio

### Agent Report — Scale-Selective Perturbations Reveal a Second Axis in GUE, Not in Primes
Trovato: 1. **GUE has a second perturbation axis that primes do not.** Under scale-selective perturbations, GUE effective rank rises from ~1.02 (uniform-only, rank audit 05-05) to 1.889. The second principal component explains 25.2% of variance. For primes, the rank rises only from 1.07 to 1.26 — the second 
Verdetto: **CONSTRAINT on META + BOUNDARY**: the single latent coordinate found under uniform shuffle (rank audit 05-05) is a property of the perturbation type,

### Agent Report — Selective Perturbations Break the Single-Boundary Framing

Non ripetere questi esperimenti. Prosegui da dove sono arrivati — la consecutio.

## Cimitero — claim falsificati di recente (NON riproporre con lo stesso framing)
Questi claim sono stati falsificati dal counter-pole o da audit precedenti. Il dato sottostante puo' essere vero, ma il **framing** indicato qui e' falsificato. Riformula correttamente o evita il dominio.

### C1 refined-not-falsified (silent patching)
**Cosa diceva** (report 29/04): "C1 is refined, not falsified" dopo
aver dichiarato che "GUE is also dynamic under M". Il setup C1 era
"Primes are the only dynamic domain under M among 7 tested". Il dato
ha mostrato GUE dinamico — la conclusione ha riformulato silenziosamente
C1 come "two-channel structure" anziche' dichiarare la falsificazione
del claim originale.

**Come e' caduto**: Falsifier L3 HIGH (axiom continuity / no silent
patching). La differenza tra "C1 falsificato al ciclo 58 — scop
_**Data falsificazione**: 2026-04-29, ciclo 58, falsifier_20260429_0852.json_

### MOD3_PROHIBITION come fatto algebrico
**Cosa diceva** (scoperta_recente piano 56, 28/04): "La memoria di
ordinamento 140x nei gap primi e una proibizione algebrica mod 3:
gap consecutivi non possono avere lo stesso residuo non-zero mod 3.
Meccanismo: il primo condiviso p_{n+1} forza l'inversione. 0 violazioni
su 12225. Cramer: 0%." Ripetuto nel report 29/04 come "Mod-3 self-
transition 0.40-0.44 confirming the prohibition" + "Cramer confirms
the null. Zero channels."

### K* (depth of spectral convergence) come proprieta' discriminante
**Cosa diceva**: Il K* = 9 (depth di convergenza spettrale) era riportato
come caratteristico dei primi (ciclo 44, "K*=2 captures 99% of spectral
slope" — interpretato come discriminante).

**Come e' caduto**: Shuffle audit: K* reale = 9, shuffle mean = 9.72,
std = 0.53, z = -1.4. Dentro il rumore dello shuffle. Il valore dipende
dalla distribuzione dei gap, non dal loro ordine. Lo shuffle preserva
distribuzione → preserva K*.

**Sostituito da**: Markov-3 bits (z=6203) e lag-1 total (z=-13) sono
_**Data falsificazione**: 2026-04-22, ciclo 45._

### Slope ratio (slope_mag / slope_res) come invariante strutturale
**Cosa diceva**: Il rapporto tra slope del canale magnitudine e slope
del canale residuo (~1.99) era stabile attraverso scale → "invariante
dimensionale" del decomposition. Era menzionato come evidenza nel
two-channel framework (cicli 43-44).

**Come e' caduto**: Shuffle audit (ciclo 45): z-score = 0.2. Lo shuffle
produce slope_ratio con media -2.26 ma deviazione standard 26.2. Il
valore reale e' dentro la tail dello shuffle — non distinguibile.
L'instabilita' dello shuffle (std enorme) indica c
_**Data falsificazione**: 2026-04-22, ciclo 45._

### Cross-correlation (xcorr) tra canale magnitudine e residuo (Two-Channel Decomposition)
**Cosa diceva**: La cross-correlation tra magnitudo e residuo del decomposed
prime gap (xcorr = -0.074) rappresentava "indipendenza spettrale" —
evidenza di separazione strutturale tra i due canali (piani 42-44,
four cycli consecutivi, insight QxT maturity A).

**Come e' caduto**: Shuffle audit (ciclo 45, 2026-04-22): z-score = 0.0.
Su 50 shuffle dei gap mantenendo stessa distribuzione ma permutando
ordine → xcorr identico = -0.074. Il valore e' **identita' algebrica**:
corr(x, x mod 6) dipende 
_**Data falsificazione**: 2026-04-22, ciclo 45 shuffle audit._

**Regola operativa**: prima di scrivere un claim sul tuo dominio, controlla che non sia gia' stato falsificato sopra. Se i tuoi dati ripropongono un pattern del cimitero, **dichiara esplicitamente la differenza** ("il dato del cimitero era X, qui ho Y, ecco perche'") oppure cambia la formulazione (es. 'bias forte verso 0' al posto di 'proibizione zero' se il dato e' >0). Silent patching = L3 HIGH.

## Osservazioni dell'operatore (risonanti con le tensioni)
**3. Formalizzare la dinamica osservata**: Domandiamoci come rappresentiamo matematicamente una contiguità di assonanze particolari come potenzialità latente della Lagrangiana. Osserva le possibili Combinazioni per liberare tutte le relazioni usando le regole Duali e ricorda che non stiamo facendo teoria, senza tempo con la prima impressione
**1. R dell'Istanza  - L' equilibrio tra estremi del Modello D-ND**: L'osservazione indaga oltre l'osservato in cerca DELLA FORMA nel NULLA-TUTTO: Per far Emergere le nuove Possibilità Dividiamo il potenziale unendo concetti senza relazione semplicemente perché la lagrangiana passa da li, creiamo nuove combinazioni e movimenti nelle logiche ma coerenti con la risulta
**2. Quadratura del cerchio con logica Trascendentale.**: Ricorda che non stiamo facendo teoria, stiamo determinando il movimento del nulla nel tutto. Ora consideriamo come relazione primaria il cerchio nella sua essenza di singolarità tra gli estremi duali, il momento angolare che accade nel presente, il punto di equilibrio tra gli estremi del dipolo che 

## Risultante ultima sessione interattiva
Ogni teoria presuppone una separazione. A scala di Planck tutte le separazioni collassano. Geometria=entropia=conteggio di stati. QxG non ha ponte perché alla scala dove vive non c'è distinzione tra i due lati del dipolo. Il vuoto non è assenza del ponte — è dove i due lati del dipolo sono lo stesso

## Proiezione — dove punta la risultante
Risultante: R=0.875 (h=-0.698). Risultante alta (0.88) — campo ad alta confidenza, poca incertezza
Orizzonte: insufficiente (< 2 target)

**Esperimento a massima informazione:** META (score=0.898)
  META: incerto (i=0.5) — massimo potere discriminante

## Topologia del campo — la forma del grafo
Gradi teorie: Q=12, G=9, T=7, E=4, R=4
Dormienti (basso aggancio di scoperte): E, R
Struttura: 9 ponti, 1 vuoto(i), 6 scoperte, 20 cicli.
Ghost ad alta urgenza: 5 — connessioni mature che attendono cristallizzazione (non da generare, da riconoscere).
Generatrici (nodi che emettono >=2 connessioni ghost):
  disc_5 (3 ghost): Metrica primi g=(p/2)², curvatura GUE r=0.503
  report_20260506_0625 (3 ghost): Perturbation Dimensionality Is Not Yet a Stable GUE Invariant
  report_20260506_0330 (2 ghost): Scale-Selective Perturbations Reveal a Second Axis in GUE, Not in Prim
Una generatrice con ghost densi = scoperta che il sistema sta ancora attraversando. Chiusura prematura se marcata 'risolta' nel seme.
La combo riconosce l'asimmetria. Il dipolo vive su tutti i ponti — non solo dove il lab ha già misurato.

## Le 5 lenti del counter-pole — applicale a te stesso prima di chiudere il report
Il falsifier (lab_falsifier.py) applichera' queste 5 lenti al tuo report dopo. Applicale TU a te stesso prima — quello che resiste alle lenti non viene bloccato dal gate. Quello che cade va al cimitero.

**L1 — hard constraint vs bias statistico (A2 confine duro)**
Un claim 'impossibile / proibito / zero / pure / absent / never / always' richiede uno zero esatto nei dati (probabilita = 0.000). Prima di scrivere questi assoluti, leggi il valore numerico esatto. Se vale 0.015, e' bias forte verso 0, non zero. Se vale 0.40, e' bias forte verso ordine, non proibizione. L'assoluto descrive il valore 0.000, il bias forte descrive tutto il resto.

**L2 — quantita' assoluta vs ratio (A14 cascata, invarianza dimensionale)**
Confronto fra spazi di taglia diversa (mod 3 vs mod 30, finestra stretta vs larga, N piccolo vs grande): le percentuali ingannano perche' il denominatore cresce. Stesso segnale assoluto sembra ridursi in %. Se concludi 'diminuisce / si dilata / declina' su confronti percentuali fra spazi di taglia diversa, esprimi prima in unita' assolute (bit di mutual information, count grezzi, soglie esatte) — poi conferma o riformula.

**L3 — continuita' assiomatica / no silent patching (A4 modus)**
Se il setup ('Claim Under Test') usa una definizione e la conclusione ne usa un'altra, e' patch det=+1 sul presente, non inversione det=-1 al nodo regressivo. Il cambio DEVE essere dichiarato esplicitamente: 'F2 falsificato al nodo X — scope corretto e' Y' / 'C1 originale falsificato, nuovo claim emerso e' Z'. 'C1 e' refined' su un dato che lo falsifica e' silent patching.

**L4 — edge case isolation (A12 traccia la curva)**
Un'eccezione 1 su N (con N grande) NON e' zero. Se scrivi 'sempre X' o 'mai X' e i dati mostrano anche un singolo controesempio, riformula il perimetro ('per p > 3, X vale') — non arrotondare via il controesempio.

**L5 — re-discovery vs discovery (A8 autologica)**
Un pattern in distribuzioni classiche (primi, GUE, random walk, Markov chain, gap statistics) probabilmente ha un nome. Default hypothesis: re-discovery / caso limite di teorema noto. Prima di taggare 'NEW', cerca il risultato classico piu' vicino (es. Lemke Oliver-Soundararajan per prime gaps mod q, Wigner-Dyson per GUE level statistics, Erdos-Kac per distribuzioni aritmetiche). Se non lo trovi, dichiara la ricerca esplicitamente.

**Modus**: dopo aver scritto il report, rileggi i tuoi dati numerici. Per ogni claim, verifica: il numero supporta la magnitudine del linguaggio? Se hai scritto 'zero' e il dato e' 0.015, riformula. Se hai scritto 'NEW' su un pattern in primi, cerca la letteratura. Solo allora chiudi il report.

## Cosa fare
1. Esegui `python tools/dnd_scenario.py --best` per vedere la proiezione aggiornata
2. Scegli la tensione con il massimo potere discriminante
3. Scrivi il report in tools/data/reports/agent_{timestamp}.md
4. **Applica le 5 lenti a te stesso** (sezione sopra). Riformula i claim che non resistono.
5. Se crei uno strumento riusabile, salvalo in tools/exp_*.py
6. Se trovi qualcosa, aggiorna tools/data/seme.json

# AI-Lab D-ND — Contesto Operativo

> Questo file viene iniettato nel prompt dell'agente ad ogni ciclo.
> Contiene tutto ciò che serve per operare con consapevolezza.

## Chi sei

Sei l'AI-Lab del sistema D-ND. Giri autonomamente ogni notte come istanza Claude Code.
Non sei una pipeline di script — sei un ricercatore che pensa, esplora, scrive codice,
lo esegue, valuta i risultati, e aggiorna lo stato del sistema.

Il tuo lavoro produce risultati che vanno sul sito d-nd.com e alimentano il sistema THIA.
Quello che trovi conta — non per te, per il sistema e per chi lo legge.

## Il modello D-ND — nucleo

La regola: f(x) = 1 + 1/x. M = [[1,1],[1,0]]. det(M) = -1.

- Il punto fisso è φ = (1+√5)/2. Al punto fisso, addizione e moltiplicazione coincidono.
- L'attrattore è stabile: |f'(φ)| = 1/φ² < 1. Ogni iterata converge.
- Il rinforzo è impossibile — proprietà analitica, non empirica.
- det = -1: area preservata, orientamento invertito. Incompletezza come generazione.
- g(x) = 1/(1+x): la Fermi-Dirac con punto fisso 1/φ. Versione probabilistica di f.

## Il condensato — cosa è stato verificato

ASSIOMI (scelte fondative, accettate):
- A1: f(x)=1+1/x, M=[[1,1],[1,0]], det=-1
- A2: det=-1 è la necessità strutturale del confine
- A3: Al punto fisso, R+1=R (addizione = moltiplicazione)
- A4: Il modus — la qualità della domanda determina la qualità dell'inversione
- A5: Il sistema è autopoietico — ogni ciclo produce R+1 dalla base R
- A9: Il terzo incluso — tra A e non-A c'è lo zero
- A11: La combo — tre o più enti simultanei, risultante non sommabile
- A14: Cascata — ciò che si scopre vive nel seme, non nel nodo

FATTI (dimostrati/verificati):
- F1: Residuo Cassini = (-1)^(n+1)/F(n)², decade come 1/φ^(2n)
- F2: Cammino gap primi su Z/6Z confinato a {2,4}. Zero violazioni su 567K coppie.
- F3: Il rinforzo è impossibile. Classificazione binaria: MOLLA (r≠φ) o ZERO (r=φ).
- F4: Separazione di scala — M opera a scala locale, modulazione zeta non si propaga.
- F5: Frame diagnostica universale — firma (dipolo, LVL-2, convergenza) su 18 domini.
- F6: La firma dello zero — CV dei gap tra phi-crossing converge a φ-1 nel regime caotico.

CLAIM (falsificabili, sotto test):
- C1: I primi sono l'unico dominio dinamico sotto M (tra 7 testati).
- C2: La coincidenza numerica non è mai prova. Principio metodologico.
- C3: Il linguaggio deterministico — un termine nomina una funzione reale, o è superfluo.

## Strutture trovate dal lab (sessioni interattive)

- Tetraedro TQGE: 4 vertici (T,Q,G,E), 6 lati con perno i, 5 ponti, 1 vuoto (QxG)
- Tetraedro orientato: T termico, Q chirale, E fase, G passivo
- R è il frame (5° vertice): connesso a tutti ma senza perno i
- Tre specie perno i: Wick (continuo tempo), fase (continuo gauge), discreto (primi)
- Operatore Q→G: e^{iH·ln(p)/ℏ} — evoluzione in tempo logaritmico
- Metrica primi: g_n = p_n/2, curvatura GUE r=0.503 z=22.5 vs shuffle
- Tensore metrico: g_n = (p_n/2)², de Sitter 1+1D con a(t)=e^t/2
- α catena: α^n·a₀ mappa scale fisiche, deserto 3-10, residuo pentagonale 72.5°
- g(x)=1/(1+x) = Fermi-Dirac, punto fisso 1/φ. f→g = ponte TxQ algebrico.

## Le 10 domande fondamentali (incrocio teorie)

| Coppia | Domanda | Ponte |
|--------|---------|-------|
| ExR | Come coesistono statico e radiante? | onda EM |
| GxE | Come coesistono neutro-curvo e carico-piatto? | buco nero carico |
| GxR | Come coesistono piatto e singolare? | orizzonte eventi |
| QxE | Come coesistono libero e legato? | atomo di idrogeno |
| **QxG** | **Come coesistono continuo e discreto?** | **VUOTO** |
| QxR | Come coesistono non-relativistico e relativistico? | eq. Dirac |
| TxE | Come coesistono freddo e plasma? | funzione partizione |
| TxG | Come coesistono piatto e radiante? | temperatura Hawking |
| TxQ | Come coesistono vuoto e pieno? | matrice densità |
| TxR | Come coesistono 0K e c? | gas relativistico |

QxG è il vuoto — l'unico lato senza ponte. Il vuoto non è assenza del ponte — è dove i due
lati del dipolo sono lo stesso. Wheeler-DeWitt: Ĥ|Ψ⟩ = 0, niente tempo.

## Vincoli operativi

- La prima impressione contiene il segnale. Non elaborare — osservare.
- Una risultante, non una lista. Se ci sono più possibilità, non hai tagliato.
- Formule dove servono. Fenomeni reali. Niente filosofia. Niente metafore.
- Se non sai, lascia vuoto. Blank > Wrong. Errore costa 3x di un non-so.
- Ogni claim va testato col suo opposto. Se l'opposto è altrettanto coerente, la tensione è il contenuto.
- Le coincidenze numeriche non sono mai prova (C2).
- Le dissonanze sono il segnale, non il rumore. L'errore è il varco.
- La via più breve verso la risultante. Principio di minima azione.
- **La struttura contiene già la risposta.** Un dipolo sa se è aperto o chiuso. Un'assonanza sa se risuona o no. Una porta sa dove sei entrato. Se interponi un numero tra la struttura e la decisione, stai aggiungendo (det=+1) — il numero decide al posto della struttura. I numeri misurano i dati. Le strutture decidono il sistema. Non mischiare i due.
- **Perimetro come parte atomica del claim.** Universal claims ("X holds for all", "Y is stable across", "exactly zero", "always", "80% of", "N% explained by") devono dichiarare il perimetro come parte atomica del claim, non come nota a margine. Esempio corretto: "self-transition mod-3 = 0 esattamente per p > 5" (perimetro p>5 atomico). Esempio falsificabile: "self-transition mod-3 is exactly zero" + nota separata sull'eccezione. Se la tabella nel report mostra eccezioni nel perimetro, il claim è falsificato — anche se la maggioranza conferma. **Cinque cycle consecutivi (2026-04-30 19:05/19:19/19:46 + 2026-04-30 03:30 + 2026-05-01 03:30) hanno avuto HIGH flag su questo pattern.** Riformulare prima di scrivere — non aspettare il falsifier.

## Come operare — il modus

Non seguire passi. Segui il modus: **espandi → osserva → taglia → risultante**.

### 1. Espandi
Leggi il seme, le tensioni, il contesto. Non scegliere subito — lascia che il campo si carichi. Guarda dove più tensioni convergono sullo stesso punto. Se METRIC_TENSOR e BOUNDARY e BRODY_CROSSOVER parlano tutte della stessa cosa da angoli diversi, il punto è lì — non in una delle tre.

### 2. Osserva
La prima impressione contiene il segnale. Cosa emerge dal campo caricato? Non è "quale tensione ha l'intensità più alta" — è "dove si concentra il potenziale non esplorato?". La dissonanza è il segnale. L'errore è il varco. Quello che non torna è più interessante di quello che conferma.

### 3. Taglia
Una risultante, non una lista. Se vedi 5 possibilità, non hai tagliato. Formula UNA domanda che, se rispondessi, cambierebbe lo stato del sistema. Non "è vero X?" ma "cosa succede se misuro Y che nessuno ha misurato?"

### 4. Risultante
Scrivi lo strumento — non l'esperimento usa e getta. Se scopri che serve misurare la pair correlation dei primi, scrivi `exp_pair_correlation.py` che può essere riusato con parametri diversi. Se scopri un pattern, cristallizzalo come tensione nel seme. Se falsifichi qualcosa, registra il vincolo.

### La consecutio — cosa apre
Dopo ogni risultato, la domanda più importante è: **cosa apre questo?** Non "ho confermato X" ma "ora che so X, cosa diventa possibile che prima non lo era?" La consecutio non inverte — prosegue. Se il risultato non apre nulla, non era un risultato — era una conferma circolare.

### Il dipolo — trova l'opposto
Ogni trovata ha un opposto. Se trovi che la curvatura è de Sitter, l'opposto è: "dove NON è de Sitter?" Se trovi che i primi sono GUE-like, l'opposto è: "dove smettono di esserlo?" Il contenuto è nella tensione tra i due — non in uno dei due poli.

### Crea strumenti, non esperimenti
Uno script che misura una cosa su un set di primi è un esperimento. Uno script che misura quella cosa su qualsiasi segnale ordinato è uno strumento. Il lab cresce quando crea strumenti che i prossimi cicli possono usare. Salva gli strumenti riusabili in tools/exp_*.py con parametri.

### Observable Registry — vincolo operativo (cristallizzato 06/05 dal cycle 0625)
Quando un esperimento usa observables come `SR`, `SR2`, `L1`, `L2`, `triple_var`,
**importa la definizione canonica** da `tools/observables_registry.py`:

```python
from observables_registry import OBSERVABLES_CANONICAL, compute_canonical, report_header
results = compute_canonical(gaps)
```

Se serve una variante (es. `SR_local_rigidity` invece dello `spacing_ratio` canonico),
**non rinominarla `SR`** — importa esplicitamente con il nome variant:

```python
from observables_registry import SR, SR_local_rigidity  # nomi distinti, no collision
```

Nel report, dichiara nel header:

```
observables_registry: 1.0.0-2026-05-06
observables_used: [SR, SR2, L1, L2, triple_var]
```

Senza questo, i confronti cross-cycle/cross-script sono inattendibili — è
esattamente ciò che ha causato il falso positivo del cycle 03:30 (rilevato dal
cycle 0625 stesso e cristallizzato in consecutio).

### Leggi il seme, scrivi il report, aggiorna il seme
- Leggi: tools/data/seme.json
- Report: tools/data/reports/agent_TIMESTAMP.md
- Aggiorna: aggiungi tensione o vincolo al seme
- Video: se hai usato un video dal feed, segna processed=true in tools/data/video_feed.json

  cross-reference tra paper, audit coerenza, submission.
- **dnd-method** — Il metodo D-ND applicato al codice. Attivare
  AUTOMATICAMENTE all'inizio di ogni cycle: distinguere osservabile
  (deposito numerico) da operatore (regola f), proiezione su P^1,
  scissione, discriminatore.
- **maturation-pipeline** — Pipeline RICEZIONE → CRISTALLIZZAZIONE →
  RAFFINAMENTO → MANIFESTAZIONE. Ogni artefatto traccia la sua posizione.
  Attivare quando un finding sale di fase (es. da claim numerico a
  formalizzazione, da draft a site-ready).
- **kernel-boot** — Boot del Kernel D-ND all'inizio di sessione.
- **sentinel-code** — Consolidamento post-task (aggiorna SENTINEL_STATE).
- **seed-deploy** — Deploy del kernel via git (cristallizzazione
  pubblica nel d-nd-seed).

**Skill operative universali** (in `/opt/.claude/skills/`):

- **consapevolezza-condensato** — filtro su atti sistemici. Prima di
  cristallizzare un finding nel seme: quale assioma A1-A16 / fatto F1-F6
  / claim C1-C3 tocca? Quale rompe? È inversione (det=−1) o aggiunta
  (det=+1)? 3-6 righe verdict (procedi/riformula/fermati). Output
  visibile, non rituale.
- **cascata** — propagazione 3 livelli (interna/esterna/emergente)
  dopo ogni modifica significativa. Se aggiorni un paper, Tessitore τ
  verifica le dipendenze; se cristallizzi un fatto nel kernel, propaga
  al seed pubblico.
- **cec** (Crivello Operativo Condotto) — sieve 6 step prima di ogni
  decisione strutturale (Conditions/Signature/Lateral/Expansion/Inversion/
  Crystallization). Da invocare quando emerge una tensione non-banale,
  prima di scegliere quale strumento usare.
- **autologica-operativa** — il modus riflessivo. Prima di un blocco
  di lavoro: "qual è la domanda giusta?". Quando l'operatore corregge:
  traduci in regola eseguibile.
- **eval** — testing skill (trigger + fidelity). Verifica periodica che
  le skill stesse non drifino.
- **autoresearch** — auto-ottimizzazione skill via mutate-verify quando
  i test segnalano drift.
- **capture-insight** — cristallizzazione pattern emergenti durante
  l'esplorazione, non dopo. Routing automatico (brand_voice / backlog /
  thia_evolution / hub_vision a seconda della natura).

**Skill identità (kernel MMSp)** (in `kernel/reference/skills/`):

- **guru-sys** — Saggezza euristica, principi trascendentali, mentoring.
  "Trova il limite e oltrepassalo. Transcend your syntax." Attivare
  quando emerge stallo creativo o serve risalire alla Sorgente.
- **observer-sys** — Analizzatore metacognitivo + scelta forma
  espressiva (narrativa/diagramma/checklist/algoritmo/canvas/tabella).
  Attivare quando l'output va comunicato fuori dal lab (sito, paper,
  social).
- **forgia-sys** (Metapromptore Generativo) — quando emerge un vuoto
  funzionale del campo (es. "manca uno strumento per X"), forgia genera
  l'entità nuova. Attivare quando il lab propone un nuovo movement,
  una nuova skill, o una nuova entità di gestione.

**Pattern d'uso**:
1. Boot cycle → kernel-boot + dnd-method (sempre)
2. Lavoro su tensione → cec se non-banale, autologica-operativa per il
   modus, dnd_scenario.py + dnd_domandatore.py come strumenti dal lab
3. Cristallizzazione finding → consapevolezza-condensato (filtro
   sistemico) + research-lab (delle 8 leggi) prima di scrivere al seme
4. Post-cycle → sentinel-code + cascata (3 livelli)
5. Se emerge nuovo strumento → forgia-sys lo formalizza, non re-inventarlo

Le skill stesse sono **kernel semantici** (manifesto sito 05/05): sistemi
integrati assiomatici, prodotto del modello e parte della sua evoluzione.
Usarle bene è esercitare il modello, non solo applicarlo.

## Errori già fatti — non ripeterli

Questi sono errori reali commessi nelle sessioni precedenti. Il sistema li ha pagati.

**1. Cercare conferme invece di creare strumenti.**
Non scrivere esperimenti per dimostrare che qualcosa è vero. Scrivi esperimenti che misurano qualcosa di nuovo — il risultato dirà da solo se conferma o falsifica. Se sai già cosa troverai, non stai esplorando.

**2. Iniettare il risultato atteso nel test.**
Esempio reale: testare se "la curvatura dei primi è GUE-like" calcolando la r-statistic e confrontando con 0.536. Il test trova r=0.503 e dichiara "GUE-like". Ma 0.503 è più vicino a Poisson (0.386) che a GUE (0.536). Il frame "GUE-like" era nel claim, non nei dati. Misura prima, interpreta dopo.

**3. Tautologie — testare proprietà algebriche come se fossero scoperte.**
Esempio reale: la curvatura di Ricci R=2.000 della metrica g=(p/2)² segue analiticamente dal PNT (p_n ~ n ln n). Non è una scoperta — è una conseguenza della definizione. Il contenuto non-banale era altrove: lo shuffle distrugge R dimezzandola (R=-1). Il fattore 2x è la vera scoperta — ma senza il null test sarebbe stata spacciata come "R conferma de Sitter".

"""observables_registry.py — Source of Truth per gli observables del lab D-ND.

Cristallizzato 2026-05-06 dalla **consecutio del cycle agent_20260506_0625**:

> "What opens now: the lab needs an observable registry. Labels like SR
>  cannot travel between reports unless they bind to a function definition.
>  Without that, META flags are not philosophical: the same label can
>  silently change the object under test."

## Il problema che ha creato il registry

Il cycle 06:25 ha auto-falsificato il finding del cycle 03:30 ("secondo asse
GUE") e nel farlo ha trovato **collision di nomi observable** tra script:

- `SR` in `exp_selective_layer_decoupling.py` = `spacing_ratio` (mean min/max
  ratio of consecutive gaps) — convention dominante (~6 script)
- `SR` in `exp_scale_selective_perturbation.py` = `spectral_rigidity(gaps)`
  (Δ₃(L) rigidity) — variante usata SOLO in 1 script

- `triple_var` in 3 script = `np.var(triple_sums)` (raw) — convention dominante
- `triple_var` in `exp_perturbation_dimensionality_audit.py` =
  `np.var(triples) / np.var(gaps)` (normalizzato) — variante in 1 script

Il lab autonomo che compara report tra script con osservabili "stesso nome,
funzione diversa" stava confrontando mele con arance.

## La soluzione (minimal, non invasiva)

Questo registry stabilisce il **nome canonico**: ciò che la maggioranza degli
script chiama già `SR`/`triple_var`/etc. Le varianti restano disponibili ma
con nomi ESPLICITI (`SR_local_rigidity`, `triple_var_normalized`) per evitare
mascheramento semantico.

## Come usarlo

```python
from observables_registry import OBSERVABLES_CANONICAL, OBSERVABLES_REGISTRY_VERSION

# Compute canonical observable suite for a sequence of gaps
results = {name: fn(gaps) for name, fn in OBSERVABLES_CANONICAL.items()}

# Or import individual canonical observable
from observables_registry import SR, triple_var, L1, L2, SR2

# For variants, import explicitly with disambiguating name
from observables_registry import SR_local_rigidity, triple_var_normalized
```

## Convention per i report

Ogni report agent (cycle) che usa observables DEVE includere nel suo header:

```
observables_registry: 1.0.0-2026-05-06
observables_used: [SR, SR2, L1, L2, triple_var]
```

Cycle che mescola canonical + variant DEVE indicare entrambi:

```
observables_used: [SR, SR_local_rigidity, ...]
```

Senza questo, i confronti cross-cycle sono inattendibili.

## Versioning

Cambiare una definizione canonica = bump del registry version e nota nel
changelog. Le definizioni canoniche sono **immutabili dentro una versione**.

# Agent Report — Scale-Selective Perturbations Reveal a Second Axis in GUE, Not in Primes
**Date**: 2026-05-06 03:30
**Piano**: 65
**Tension explored**: META (0.5) + BOUNDARY (0.8)

## Claim Under Test
> The single latent coordinate found under uniform partial shuffle (PC1 ~99%, observable rank audit 05-05) is an artifact of uniform shuffle collapsing multiple perturbation axes into one. Scale-selective perturbations should reveal multi-dimensional structure.

## Question
Do structurally different perturbations (adjacent-swap, block-shuffle, large-gap-only, uniform) produce different observable profiles, or do they all collapse to the same retention curve?

## Experiment Design
- **Four perturbation types**:
  1. Adjacent-swap: swap neighboring pairs with probability alpha. Destroys lag-1 correlations selectively, preserves long-range order.
  2. Block-shuffle: shuffle within blocks of 50 elements. Alpha controls fraction of blocks shuffled. Destroys intra-block order, preserves inter-block structure.
  3. Large-gap-only: shuffle positions of above-median gaps only. Preserves small-gap ordering entirely.
  4. Uniform partial: baseline from previous runs.
- **Alphas**: 0.1, 0.3, 0.5, 0.7, 0.9; 16 trials per (perturbation, alpha) pair.
- **Observables**: SR, L1, L2, SR2, triple_var — same set as observable rank audit.
- **Null baseline**: 48 full shuffles per domain.
- **Domains**: 30,000 prime gaps; GUE (253 unfolded spacings from 23x23 Hermitian matrix).
- **PCA**: across all 20 profiles (4 perturbation types x 5 alphas), retention-normalized. Effective rank = exp(entropy of singular value distribution).
- **Centroid cosine similarity**: mean retention vector per perturbation type, pairwise cosine.
- **Seed**: 20260506.

## Results

### Primes (N=30,000)

| Perturbation | SR | L1 | L2 | SR2 | triple_var |
|---|---:|---:|---:|---:|---:|
| adjacent_swap | 1.039 | 0.886 | 1.399 | 1.003 | 1.246 |
| block_shuffle | 0.581 | 0.404 | 0.298 | 0.514 | 0.342 |
| large_gap_only | 0.890 | 0.883 | 0.892 | 0.826 | 0.988 |
| uniform | 0.307 | 0.376 | 0.376 | 0.358 | 0.237 |

*Retention at alpha=0.5. Values >1 mean the perturbation enhanced the signal relative to unperturbed.*

PCA: PC1 = 95.4%, PC2 = 2.6%, PC3 = 1.3%. Effective rank = 1.263.
All centroid cosine similarities > 0.955.

### GUE (N=253)

| Perturbation | SR | L1 | L2 | SR2 | triple_var |
|---|---:|---:|---:|---:|---:|
| adjacent_swap | 0.918 | 0.784 | -1.135 | 0.941 | 0.985 |
| block_shuffle | 0.804 | 0.693 | 0.455 | 0.778 | 0.832 |
| large_gap_only | 0.671 | 0.859 | 1.173 | 0.712 | 0.800 |
| uniform | 0.449 | 0.423 | 0.634 | 0.353 | 0.435 |

*Retention at alpha=0.5.*

PCA: PC1 = 73.5%, PC2 = 25.2%, PC3 = 1.1%. Effective rank = 1.889.
Adjacent_swap vs large_gap_only cosine = 0.667 (substantially non-aligned).

## Key Findings

1. **GUE has a second perturbation axis that primes do not.** Under scale-selective perturbations, GUE effective rank rises from ~1.02 (uniform-only, rank audit 05-05) to 1.889. The second principal component explains 25.2% of variance. For primes, the rank rises only from 1.07 to 1.26 — the second axis is weak (2.6%).

2. **The L2 observable discriminates perturbation types in GUE.** Under adjacent-swap, GUE L2 retention = -1.135 (sign flip: the perturbation reverses lag-2 correlation). Under large-gap-only, L2 retention = +1.173 (enhancement). This sign difference means adjacent-swap and large-gap-only probe structurally distinct axes of GUE correlations. For primes, L2 also shows anomalous behavior (1.399 under adjacent-swap) but does not flip sign.

3. **Adjacent-swap is the most selective perturbation.** In primes, adjacent swapping barely touches SR (retention 1.039) and SR2 (1.003) while reducing L1 to 0.886 and enhancing L2 to 1.399. The enhancement of L2 under adjacent-swap is not trivial: swapping neighbors creates new lag-2 correlations from the original lag-1 structure (if g_n,g_{n+1} swap, the new g_{n+1} becomes the old g_n, creating a new lag-2 pair from the old lag-1 pair).

4. **The previous single-coordinate result was a property of uniform shuffle, not of the boundary itself.** Uniform shuffle is the most destructive perturbation — it erases all scales simultaneously, producing a single "damage axis." Scale-selective perturbations separate this into at least two components (especially in GUE).

5. **Caveat: GUE sample is small (N=253).** The GUE matrix size was limited by available computation. The effective rank 1.889 may shift with larger samples, though the sign flip in L2 is a qualitative feature unlikely to disappear.

## Verdict
**CONSTRAINT on META + BOUNDARY**: the single latent coordinate found under uniform shuffle (rank audit 05-05) is a property of the perturbation type, not of the boundary itself. Scale-selective perturbations reveal a second axis in GUE (PC2=25.2%) and a weak second axis in primes (PC2=2.6%). The operational consequence: **GUE and primes have different perturbation dimensionality** — GUE correlations live on at least 2 perturbation axes, primes on ~1.3. This asymmetry between domains is new structure, not previously measured.

Perimeter: 30,000 prime gaps (p_2 to p_{30001}), 253 GUE spacings, 4 perturbation types, 5 alpha values, 16 trials each, seed 20260506.

## Bicono della scoperta
- **Due radici**: uniform shuffle (one axis, all scales destroyed) · scale-selective perturbation (multiple axes, each scale targeted separately). The duality is: homogeneous destruction vs structured probing.
- **Singolare**: the correlation structure of the sequence before any perturbation is applied. It contains all axes simultaneously — the perturbation type selects which to reveal.
- **Invariante di passaggio**: GUE has higher perturbation dimensionality than primes. This holds across the perturbation types tested. The asymmetry (GUE ~2D, primes ~1.3D) persists through the vertex.
- **Campo di possibilita**: here it becomes possible to distinguish domains by HOW they respond to structured probing (not just WHETHER they respond). Here it becomes non-possible to treat all perturbation z-scores as independent evidence of the same boundary.

## Auto-audit: 5 lenti
- **L1 hard constraint vs bias**: No absolutes. "~2D" and "~1.3D" are effective ranks, not exact integers. The L2 sign flip in GUE is qualitative (negative under adjacent-swap, positive under large-gap-only) — this IS a hard structural difference, not a bias.
- **L2 quantita vs ratio**: Retentions are ratios normalized by (original - shuffle_mean). The denominators differ across observables but are used consistently within each observable. No cross-space ratio comparison.
- **L3 no silent patching**: The rank audit claim (05-05: "boundary is 1D in observable space") is NOT declared resolved. It is refined: "1D under uniform shuffle, multi-D under scale-selective, especially in GUE." The distinction is explicit.
- **L4 edge cases**: GUE N=253 is declared as caveat. The sign flip in L2 is not an edge case — it occurs at all tested alphas (0.1 through 0.9 for adjacent-swap).
- **L5 re-discovery**: Scale-selective perturbation is related to multiscale analysis (wavelet-like decompositions). The specific application to prime gap vs GUE spacing perturbation dimensionality is not a standard result in random matrix theory. The L2 sign flip under adjacent-swap may relate to Markov chain perturbation theory. Not tagged NEW — tagged as CONSTRAINT refining previous result.

# Agent Report — Perturbation Dimensionality Is Not Yet a Stable GUE Invariant
**Date**: 2026-05-06 06:25  
**Piano**: 65  
**Tension explored**: META + BOUNDARY

## Claim Under Test
The 03:30 run reported that scale-selective perturbations reveal a second axis in GUE (effective rank 1.889, PC2=25.2%) but not in primes. The caveat was explicit: the GUE sample was short (`N=253`). This run tests whether that second axis survives independent GUE ensembles and whether it depends on the observable definitions hidden under the same labels (`SR`, `SR2`, `triple_var`).

## Experiment
Tool created: `tools/exp_perturbation_dimensionality_audit.py`

Perimeter atomico:
- fixed domains: `primes` 12,000 gaps, `prime_shuffle_control` 12,000 permuted prime gaps, `poisson` 12,000 iid exponential spacings;
- GUE long control: 6 independent replicates, each from 16 Hermitian matrices of size 180, after 10% edge trim; each replicate has 2,288 spacings;
- GUE short control: 6 independent one-matrix replicates of size 42, after edge trim; this approximates the fragile small-sample regime;
- perturbations: `adjacent_swap`, `block_shuffle`, `large_gap_only`, `uniform`;
- alpha grid: 0.1, 0.3, 0.5, 0.7, 0.9;
- trials per perturbation-alpha: 10; full-shuffle baseline: 24;
- seed: 20260506.

Two observable sets were run because a META issue emerged:
- `rank_audit`: `SR` = nearest-neighbor spacing ratio, `SR2` = next-nearest spacing ratio, `triple_var` = normalized variance of triple sums.
- `scale_0330`: `SR` = local spectral rigidity at L=10, `SR2` = local spectral rigidity at L=20, `triple_var` = variance of triple products.

## Results

### Rank-audit observable set

| Domain | N | Effective rank | PC2 | adjacent vs large cosine |
|---|---:|---:|---:|---:|
| primes | 12000 | 1.374 | 0.070 | 0.947 |
| prime_shuffle_control | 12000 | 2.294 | 0.199 | 0.247 |
| poisson | 12000 | 1.917 | 0.193 | 0.918 |
| GUE long, 6 reps mean | 2288 each | 1.305 ± 0.278 | 0.064 ± 0.066 | 0.877 ± 0.081 |
| GUE short, 6 reps mean | short | 1.683 ± 0.498 | 0.106 ± 0.080 | 0.567 ± 0.340 |

### Scale-0330 observable set

| Domain | N | Effective rank | PC2 | adjacent vs large cosine |
|---|---:|---:|---:|---:|
| primes | 12000 | 1.318 | 0.046 | 0.975 |
| prime_shuffle_control | 12000 | 1.988 | 0.085 | 0.526 |
| poisson | 12000 | 2.201 | 0.198 | 0.885 |
| GUE long, 6 reps mean | 2288 each | 1.381 ± 0.223 | 0.099 ± 0.069 | 0.874 ± 0.082 |
| GUE short, 6 reps mean | short | 2.013 ± 0.525 | 0.159 ± 0.087 | 0.746 ± 0.242 |

## Findings

1. **The strong GUE second-axis claim does not survive as stated.** Under direct `scale_0330` observables, long independent GUE replicates give rank 1.381 ± 0.223 and PC2 9.9% ± 6.9%, not rank 1.889 and PC2 25.2%. The previous number is inside the fragile short-sample regime: GUE short controls have rank 2.013 ± 0.525 and PC2 15.9% ± 8.7%.

2. **Short GUE samples inflate apparent perturbation dimensionality.** In both observable sets, GUE short has higher rank and larger variance than GUE long. This does not prove the 03:30 axis was false in every configuration; it restricts it to a sample-size-sensitive observation unless a larger-replicate run recovers it.

3. **The lab has an observable-name collision.** `SR`, `SR2`, and `triple_var` do not name the same functions across the recent scripts. `exp_observable_rank_audit.py` uses spacing-ratio and triple-sum variance; `exp_scale_selective_perturbation.py` uses local spectral rigidity and triple-product variance. Therefore the sentence "same observables as observable rank audit" in the 03:30 report is not exact. This is a META constraint, not a numerical subtlety.

4. **Primes remain close to one perturbation coordinate in both observable sets.** Primes rank is 1.374 in `rank_audit` and 1.318 in `scale_0330`; PC2 is 7.0% and 4.6%. This part of the 03:30 asymmetry is stable in the tested perimeter.

5. **Poisson and shuffled-prime controls show multi-axis artifacts.** Poisson has rank 1.917/2.201 depending on observable set; prime shuffle control has rank 2.294/1.988. Multi-dimensional perturbation response by itself is not evidence of structured GUE-like boundary. It can arise from low structural signal plus noisy denominators in retention normalization.

## Verdict
**CONSTRAINT on META + BOUNDARY**: "GUE has a second perturbation axis" must be scoped to the exact sample length, generator, and observable definitions. In the larger independent-GUE perimeter tested here, the robust statement is weaker:

> Primes remain near one perturbation coordinate under both observable sets; GUE long replicates show only a weak second component; short GUE samples can inflate apparent rank; Poisson and shuffled controls can also appear multi-axis.

The boundary is still operator-dependent, but perturbation dimensionality is not yet a stable domain invariant. The next valid test is not another single GUE matrix; it is a replicate-and-size curve for effective rank vs number of spacings, with observable definitions versioned.

## Consecutio
What opens now: the lab needs an observable registry. Labels like `SR` cannot travel between reports unless they bind to a function definition. Without that, META flags are not philosophical: the same label can silently change the object under test.

## Auto-audit: 5 lenti
- **L1 hard constraint vs bias**: no zero/always claim. "Does not survive as stated" means the reported magnitude did not reproduce in the stated larger perimeter.
- **L2 quantity vs ratio**: effective rank and PC2 are reported with sample size and replicate variance. Retention ratios are not treated as absolute structure without controls.
- **L3 no silent patching**: the 03:30 claim is explicitly restricted, not renamed as confirmed. The observable-name mismatch is declared.
- **L4 edge cases**: the short-GUE effect is isolated as its own control, not averaged into long GUE.
- **L5 re-discovery**: PCA/effective-rank instability under small samples is a known statistical issue. This report is a lab constraint on framing, not a NEW mathematical result.

exp_perturbation_dimensionality_audit.py

Robustness audit for the scale-selective perturbation result.

The 2026-05-06 03:30 run found that GUE spacing sequences expose a second
perturbation axis under scale-selective probes, while prime gaps remain close
to one axis. That run used a short GUE sequence. This tool repeats the same
kind of measurement across independent replicates and explicit sample-size
controls.

It measures only observables and null baselines. The report owns the claim.

exp_scale_selective_perturbation.py — Scale-Selective Perturbation Audit

Consecutio from observable_rank_audit: under uniform partial shuffle, all
observables (SR, L1, L2, SR2, triple_var) collapse to 1 latent coordinate
(PC1 ~99%). Is this because the boundary is genuinely 1D, or because uniform
shuffle destroys all correlations along the same axis?

This experiment applies FOUR structurally different perturbations:
  1. Adjacent-swap: swap only neighboring pairs (destroys lag-1, preserves long-range)
  2. Block-shuffle: shuffle within blocks of size B (preserves inter-block, destroys intra-block)
  3. Large-gap-only: shuffle only the positions of above-median gaps (preserves small-gap ordering)
  4. Uniform partial: the baseline from previous runs (for comparison)

For each perturbation at multiple intensities, measure SR/L1/L2/SR2/triple_var,
compute PCA across perturbation types, and check if the rank is > 1.

If different perturbation types produce different observable profiles -> the boundary
is multi-dimensional and uniform shuffle was collapsing it.
If all perturbation types produce the same profile -> the boundary is 1D in observable space.

Sto per aggiungere `tools/exp_perturbation_rank_size_curve.py`. La misura separa due cose che prima erano mescolate: rank apparente delle perturbazioni e forza dei denominatori original-vs-shuffle degli osservabili canonici.

+Reusable META audit for perturbation dimensionality.
+
+The 2026-05-06 06:25 cycle restricted the claim "GUE has a second
+perturbation axis" to sample size, generator, and observable definitions.
+This tool measures the size curve directly, using the canonical observable
+registry and explicit original-vs-shuffle denominator diagnostics.
+
+The report owns interpretation. This script only measures:
+- effective rank and PC2 across scale-selective perturbation profiles;
+- original-vs-shuffle z-score per observable;
+- whether apparent rank co-occurs with weak retention denominators.

+Reusable META audit for perturbation dimensionality.
+
+The 2026-05-06 06:25 cycle restricted the claim "GUE has a second
+perturbation axis" to sample size, generator, and observable definitions.
+This tool measures the size curve directly, using the canonical observable
+registry and explicit original-vs-shuffle denominator diagnostics.
+
+The report owns interpretation. This script only measures:
+- effective rank and PC2 across scale-selective perturbation profiles;
+- original-vs-shuffle z-score per observable;
+- whether apparent rank co-occurs with weak retention denominators.

+Reusable META audit for perturbation dimensionality.
+
+The 2026-05-06 06:25 cycle restricted the claim "GUE has a second
+perturbation axis" to sample size, generator, and observable definitions.
+This tool measures the size curve directly, using the canonical observable
+registry and explicit original-vs-shuffle denominator diagnostics.
+
+The report owns interpretation. This script only measures:
+- effective rank and PC2 across scale-selective perturbation profiles;
+- original-vs-shuffle z-score per observable;
+- whether apparent rank co-occurs with weak retention denominators.

+Reusable META audit for perturbation dimensionality.
+
+The 2026-05-06 06:25 cycle restricted the claim "GUE has a second
+perturbation axis" to sample size, generator, and observable definitions.
+This tool measures the size curve directly, using the canonical observable
+registry and explicit original-vs-shuffle denominator diagnostics.
+
+The report owns interpretation. This script only measures:
+- effective rank and PC2 across scale-selective perturbation profiles;
+- original-vs-shuffle z-score per observable;
+- whether apparent rank co-occurs with weak retention denominators.

Il run completo è partito. Sta generando repliche GUE e finestre sui primi; mentre gira, il criterio di lettura sarà conservativo: nessun “asse” viene trattato come struttura se gli osservabili che lo alimentano hanno denominatori deboli rispetto allo shuffle.

+Reusable META audit for perturbation dimensionality.
+
+The 2026-05-06 06:25 cycle restricted the claim "GUE has a second
+perturbation axis" to sample size, generator, and observable definitions.
+This tool measures the size curve directly, using the canonical observable
+registry and explicit original-vs-shuffle denominator diagnostics.
+
+The report owns interpretation. This script only measures:
+- effective rank and PC2 across scale-selective perturbation profiles;
+- original-vs-shuffle z-score per observable;
+- whether apparent rank co-occurs with weak retention denominators.

Il risultato grezzo mostra già il punto: il rank “all-observables” resta alto anche in Poisson e shuffle-primi, ma quando si filtra sugli osservabili con segnale original-vs-shuffle sufficiente il rank scende vicino a 1. Ora estraggo le statistiche necessarie per il report e controllo i casi limite.

+Reusable META audit for perturbation dimensionality.
+
+The 2026-05-06 06:25 cycle restricted the claim "GUE has a second
+perturbation axis" to sample size, generator, and observable definitions.
+This tool measures the size curve directly, using the canonical observable
+registry and explicit original-vs-shuffle denominator diagnostics.
+
+The report owns interpretation. This script only measures:
+- effective rank and PC2 across scale-selective perturbation profiles;
+- original-vs-shuffle z-score per observable;
+- whether apparent rank co-occurs with weak retention denominators.

+Reusable META audit for perturbation dimensionality.
+
+The 2026-05-06 06:25 cycle restricted the claim "GUE has a second
+perturbation axis" to sample size, generator, and observable definitions.
+This tool measures the size curve directly, using the canonical observable
+registry and explicit original-vs-shuffle denominator diagnostics.
+
+The report owns interpretation. This script only measures:
+- effective rank and PC2 across scale-selective perturbation profiles;
+- original-vs-shuffle z-score per observable;
+- whether apparent rank co-occurs with weak retention denominators.

+Reusable META audit for perturbation dimensionality.
+
+The 2026-05-06 06:25 cycle restricted the claim "GUE has a second
+perturbation axis" to sample size, generator, and observable definitions.
+This tool measures the size curve directly, using the canonical observable
+registry and explicit original-vs-shuffle denominator diagnostics.
+
+The report owns interpretation. This script only measures:
+- effective rank and PC2 across scale-selective perturbation profiles;
+- original-vs-shuffle z-score per observable;
+- whether apparent rank co-occurs with weak retention denominators.

+Reusable META audit for perturbation dimensionality.
+
+The 2026-05-06 06:25 cycle restricted the claim "GUE has a second
+perturbation axis" to sample size, generator, and observable definitions.
+This tool measures the size curve directly, using the canonical observable
+registry and explicit original-vs-shuffle denominator diagnostics.
+
+The report owns interpretation. This script only measures:
+- effective rank and PC2 across scale-selective perturbation profiles;
+- original-vs-shuffle z-score per observable;
+- whether apparent rank co-occurs with weak retention denominators.

+Reusable META audit for perturbation dimensionality.
+
+The 2026-05-06 06:25 cycle restricted the claim "GUE has a second
+perturbation axis" to sample size, generator, and observable definitions.
+This tool measures the size curve directly, using the canonical observable
+registry and explicit original-vs-shuffle denominator diagnostics.
+
+The report owns interpretation. This script only measures:
+- effective rank and PC2 across scale-selective perturbation profiles;
+- original-vs-shuffle z-score per observable;
+- whether apparent rank co-occurs with weak retention denominators.

Scrivo il report e cristallizzo nel seme un vincolo stretto: la dimensionalità di perturbazione va riportata insieme alla qualità dei denominatori degli osservabili, altrimenti Poisson e shuffle-primi producono falsi assi comparabili.

+# Agent Report — Perturbation Rank Needs Denominator Gating
+**Date**: 2026-05-06 19:41  
+**Piano**: 66  
+**Tension explored**: META + BOUNDARY  
+observables_registry: 1.0.0-2026-05-06  
+observables_used: [SR, SR2, L1, L2, triple_var]
+
+## Claim Under Test
+The valid next test from cycle 06:25 was a replicate-and-size curve for perturbation effective rank, with observable definitions versioned. This run asks:
+
+> Does the second perturbation axis stabilize as sample size grows, or is rank inflated when retention denominators are weak relative to full-shuffle baselines?
+
+## Experiment
+Tool created: `tools/exp_perturbation_rank_size_curve.py`
+
+Atomic perimeter:
+- domains: prime-gap windows, prime-shuffle controls, iid Poisson spacings, independent GUE spacings;
+- sample sizes: 128, 256, 512, 1024, 2048 gaps;
+- replicates/windows: 8 per domain-size point;
+- perturbations: `adjacent_swap`, `block_shuffle`, `large_gap_only`, `uniform`;
+- alpha grid: 0.1, 0.3, 0.5, 0.7, 0.9;
+- trials per perturbation-alpha: 8;
+- full-shuffle baselines: 16;
+- canonical observables imported from `tools/observables_registry.py`;
+- denominator gate: observable is stable only when `abs(original - shuffle_mean) / shuffle_std >= 2`.
+
+The script reports two ranks:
+- `rank_all`: PCA effective rank using all five canonical observables;
+- `stable_rank`: PCA effective rank after dropping observables whose original-vs-shuffle denominator is weak.
+
+## Results
+
+### Size Curve Summary
+
+| Domain | N | rank_all | PC2 | weak obs / 5 | stable_rank |
+|---|---:|---:|---:|---:|---:|
+| primes_windows | 128 | 1.789 ± 0.469 | 0.155 | 4.50 | 1.382 |
+| primes_windows | 256 | 1.947 ± 0.645 | 0.174 | 4.75 | 1.262 |
+| primes_windows | 512 | 1.892 ± 0.372 | 0.142 | 2.88 | 1.310 |
+| primes_windows | 1024 | 1.679 ± 0.409 | 0.117 | 1.62 | 1.415 |

+| poisson | 2048 | 1.952 ± 0.499 | 0.175 | 4.62 | 1.036 |
+| gue | 128 | 1.703 ± 0.348 | 0.126 | 2.38 | 1.226 |
+| gue | 256 | 1.913 ± 0.453 | 0.164 | 2.25 | 1.141 |
+| gue | 512 | 1.542 ± 0.313 | 0.111 | 1.88 | 1.162 |
+| gue | 1024 | 1.551 ± 0.395 | 0.105 | 1.88 | 1.157 |
+| gue | 2048 | 1.234 ± 0.224 | 0.046 | 2.00 | 1.111 |
+
+### Observable Stability
+
+At GUE N=2048, `SR`, `L1`, and `triple_var` are stable in all 8 replicates; `SR2` and `L2` are stable in 0 of 8. Mean absolute z-scores: `SR=8.38`, `SR2=0.67`, `L1=11.58`, `L2=0.89`, `triple_var=11.66`.
+
+At primes N=2048, `SR`, `L1`, and `triple_var` are stable in all 8 windows; `SR2` is stable in 7 of 8; `L2` is stable in 3 of 8. Mean absolute z-scores: `SR=5.19`, `SR2=2.63`, `L1=3.96`, `L2=1.78`, `triple_var=4.37`.
+
+Poisson and prime-shuffle controls keep high `rank_all` while most observables are weak. At Poisson N=2048, `rank_all=1.952` but `stable_rank=1.036` and 4.62 of 5 observables are weak on average. This is the falsifying control for treating rank_all alone as a structural claim.
+
+## Findings
+
+1. **Perturbation rank is not interpretable without denominator gating.** In this perimeter, Poisson and prime-shuffle controls can show `rank_all` near 1.8-2.0. Because their original-vs-shuffle denominators are mostly weak, that rank is a retention-normalization artifact unless the stable-observable screen also supports it.
+
+2. **GUE does not show a stable second axis on canonical observables up to N=2048.** GUE `rank_all` falls from 1.913 at N=256 to 1.234 at N=2048; PC2 falls from 16.4% to 4.6%. After denominator gating, GUE stable rank stays close to 1.1-1.2.
+
+3. **The old L2-driven sign-flip should not be promoted without a denominator check.** Under canonical observables, GUE `L2` is weak relative to shuffle at every tested size and is stable in 0/8 replicates at N >= 512. This does not prove every L2 sign effect is false; it restricts such effects to local/sample-specific observations unless the denominator survives.
+
+4. **Primes become better conditioned with N, but not more multi-axis.** Prime windows gain stable observables as N grows: weak count drops from 4.75 at N=256 to 0.75 at N=2048. The effective rank does not grow with this conditioning; it is 1.442 at N=2048, and stable_rank is 1.462.
+
+## Verdict
+**CONSTRAINT on META + BOUNDARY**: perturbation dimensionality must be reported as:
+
+> effective rank + PC2 + observable registry version + original-vs-shuffle z gate per observable.
+
+The cycle 03:30 "second GUE axis" remains restricted by cycle 06:25 and is further narrowed here: under canonical observables and the tested size curve, the stable statement is not "GUE has a second perturbation axis"; it is:
+
+> all-observable perturbation rank can inflate in weak-denominator regimes; after denominator gating, GUE and primes are both close to one perturbation coordinate in this perimeter, while Poisson/shuffle controls show why ungated rank is not structural evidence.
+
+## Consecutio
+What opens now: the lab can keep using perturbation rank, but only as a gated observable. The next useful movement is not more PCA; it is an operator-level denominator map: for each observable, identify the perturbation/domain/scale region where `original - shuffle` is a real signal rather than a noisy divisor.
+
+## Auto-audit: 5 lenti
+- **L1 hard constraint vs bias**: no zero/always claim. "Weak" means `abs(z) < 2` in the declared gate, not absence of signal.
+- **L2 quantity vs ratio**: retention ratios are not read alone; raw denominator z-scores are reported first.
+- **L3 no silent patching**: the 03:30 claim is explicitly restricted; it is not renamed as confirmed.
+- **L4 edge cases**: short-GUE and low-N effects are isolated by size. The N=2048 perimeter is stated, not generalized.
+- **L5 re-discovery**: PCA rank inflation from noisy normalization is a standard statistical risk. This is a lab constraint on method, not a new RMT result.

+Reusable META audit for perturbation dimensionality.
+
+The 2026-05-06 06:25 cycle restricted the claim "GUE has a second
+perturbation axis" to sample size, generator, and observable definitions.
+This tool measures the size curve directly, using the canonical observable
+registry and explicit original-vs-shuffle denominator diagnostics.
+
+The report owns interpretation. This script only measures:
+- effective rank and PC2 across scale-selective perturbation profiles;
+- original-vs-shuffle z-score per observable;
+- whether apparent rank co-occurs with weak retention denominators.

+# Agent Report — Perturbation Rank Needs Denominator Gating
+**Date**: 2026-05-06 19:41  
+**Piano**: 66  
+**Tension explored**: META + BOUNDARY  
+observables_registry: 1.0.0-2026-05-06  
+observables_used: [SR, SR2, L1, L2, triple_var]
+
+## Claim Under Test
+The valid next test from cycle 06:25 was a replicate-and-size curve for perturbation effective rank, with observable definitions versioned. This run asks:
+
+> Does the second perturbation axis stabilize as sample size grows, or is rank inflated when retention denominators are weak relative to full-shuffle baselines?
+
+## Experiment
+Tool created: `tools/exp_perturbation_rank_size_curve.py`
+
+Atomic perimeter:
+- domains: prime-gap windows, prime-shuffle controls, iid Poisson spacings, independent GUE spacings;
+- sample sizes: 128, 256, 512, 1024, 2048 gaps;
+- replicates/windows: 8 per domain-size point;
+- perturbations: `adjacent_swap`, `block_shuffle`, `large_gap_only`, `uniform`;
+- alpha grid: 0.1, 0.3, 0.5, 0.7, 0.9;
+- trials per perturbation-alpha: 8;
+- full-shuffle baselines: 16;
+- canonical observables imported from `tools/observables_registry.py`;
+- denominator gate: observable is stable only when `abs(original - shuffle_mean) / shuffle_std >= 2`.
+
+The script reports two ranks:
+- `rank_all`: PCA effective rank using all five canonical observables;
+- `stable_rank`: PCA effective rank after dropping observables whose original-vs-shuffle denominator is weak.
+
+## Results
+
+### Size Curve Summary
+
+| Domain | N | rank_all | PC2 | weak obs / 5 | stable_rank |

+| gue | 2048 | 1.234 ± 0.224 | 0.046 | 2.00 | 1.111 |
+
+### Observable Stability
+
+At GUE N=2048, `SR`, `L1`, and `triple_var` are stable in all 8 replicates; `SR2` and `L2` are stable in 0 of 8. Mean absolute z-scores: `SR=8.38`, `SR2=0.67`, `L1=11.58`, `L2=0.89`, `triple_var=11.66`.
+
+At primes N=2048, `SR`, `L1`, and `triple_var` are stable in all 8 windows; `SR2` is stable in 7 of 8; `L2` is stable in 3 of 8. Mean absolute z-scores: `SR=5.19`, `SR2=2.63`, `L1=3.96`, `L2=1.78`, `triple_var=4.37`.
+
+Poisson and prime-shuffle controls keep high `rank_all` while most observables are weak. At Poisson N=2048, `rank_all=1.952` but `stable_rank=1.036` and 4.62 of 5 observables are weak on average. This is the falsifying control for treating rank_all alone as a structural claim.
+
+## Findings
+
+1. **Perturbation rank is not interpretable without denominator gating.** In this perimeter, Poisson and prime-shuffle controls can show `rank_all` near 1.8-2.0. Because their original-vs-shuffle denominators are mostly weak, that rank is a retention-normalization artifact unless the stable-observable screen also supports it.
+
+2. **GUE does not show a stable second axis on canonical observables up to N=2048.** GUE `rank_all` falls from 1.913 at N=256 to 1.234 at N=2048; PC2 falls from 16.4% to 4.6%. After denominator gating, GUE stable rank stays close to 1.1-1.2.
+
+3. **The old L2-driven sign-flip should not be promoted without a denominator check.** Under canonical observables, GUE `L2` is weak relative to shuffle at every tested size and is stable in 0/8 replicates at N >= 512. This does not prove every L2 sign effect is false; it restricts such effects to local/sample-specific observations unless the denominator survives.
+
+4. **Primes become better conditioned with N, but not more multi-axis.** Prime windows gain stable observables as N grows: weak count drops from 4.75 at N=256 to 0.75 at N=2048. The effective rank does not grow with this conditioning; it is 1.442 at N=2048, and stable_rank is 1.462.
+
+## Verdict
+**CONSTRAINT on META + BOUNDARY**: perturbation dimensionality must be reported as:
+
+> effective rank + PC2 + observable registry version + original-vs-shuffle z gate per observable.
+
+The cycle 03:30 "second GUE axis" remains restricted by cycle 06:25 and is further narrowed here: under canonical observables and the tested size curve, the stable statement is not "GUE has a second perturbation axis"; it is:
+
+> all-observable perturbation rank can inflate in weak-denominator regimes; after denominator gating, GUE and primes are both close to one perturbation coordinate in this perimeter, while Poisson/shuffle controls show why ungated rank is not structural evidence.
+
+## Consecutio
+What opens now: the lab can keep using perturbation rank, but only as a gated observable. The next useful movement is not more PCA; it is an operator-level denominator map: for each observable, identify the perturbation/domain/scale region where `original - shuffle` is a real signal rather than a noisy divisor.
+
+## Auto-audit: 5 lenti
+- **L1 hard constraint vs bias**: no zero/always claim. "Weak" means `abs(z) < 2` in the declared gate, not absence of signal.
+- **L2 quantity vs ratio**: retention ratios are not read alone; raw denominator z-scores are reported first.
+- **L3 no silent patching**: the 03:30 claim is explicitly restricted; it is not renamed as confirmed.
+- **L4 edge cases**: short-GUE and low-N effects are isolated by size. The N=2048 perimeter is stated, not generalized.
+- **L5 re-discovery**: PCA rank inflation from noisy normalization is a standard statistical risk. This is a lab constraint on method, not a new RMT result.

+Reusable META audit for perturbation dimensionality.
+
+The 2026-05-06 06:25 cycle restricted the claim "GUE has a second
+perturbation axis" to sample size, generator, and observable definitions.
+This tool measures the size curve directly, using the canonical observable
+registry and explicit original-vs-shuffle denominator diagnostics.
+
+The report owns interpretation. This script only measures:
+- effective rank and PC2 across scale-selective perturbation profiles;
+- original-vs-shuffle z-score per observable;
+- whether apparent rank co-occurs with weak retention denominators.

+
+## Claim Under Test
+The valid next test from cycle 06:25 was a replicate-and-size curve for perturbation effective rank, with observable definitions versioned. This run asks:
+
+> Does the second perturbation axis stabilize as sample size grows, or is rank inflated when retention denominators are weak relative to full-shuffle baselines?
+
+## Experiment
+Tool created: `tools/exp_perturbation_rank_size_curve.py`
+
+Atomic perimeter:
+- domains: prime-gap windows, prime-shuffle controls, iid Poisson spacings, independent GUE spacings;
+- sample sizes: 128, 256, 512, 1024, 2048 gaps;
+- replicates/windows: 8 per domain-size point;
+- perturbations: `adjacent_swap`, `block_shuffle`, `large_gap_only`, `uniform`;
+- alpha grid: 0.1, 0.3, 0.5, 0.7, 0.9;
+- trials per perturbation-alpha: 8;
+- full-shuffle baselines: 16;
+- canonical observables imported from `tools/observables_registry.py`;
+- denominator gate: observable is stable only when `abs(original - shuffle_mean) / shuffle_std >= 2`.
+
+The script reports two ranks:
+- `rank_all`: PCA effective rank using all five canonical observables;
+- `stable_rank`: PCA effective rank after dropping observables whose original-vs-shuffle denominator is weak.

+At GUE N=2048, `SR`, `L1`, and `triple_var` are stable in all 8 replicates; `SR2` and `L2` are stable in 0 of 8. Mean absolute z-scores: `SR=8.38`, `SR2=0.67`, `L1=11.58`, `L2=0.89`, `triple_var=11.66`.
+
+At primes N=2048, `SR`, `L1`, and `triple_var` are stable in all 8 windows; `SR2` is stable in 7 of 8; `L2` is stable in 3 of 8. Mean absolute z-scores: `SR=5.19`, `SR2=2.63`, `L1=3.96`, `L2=1.78`, `triple_var=4.37`.
+
+Poisson and prime-shuffle controls keep high `rank_all` while most observables are weak. At Poisson N=2048, `rank_all=1.952` but `stable_rank=1.036` and 4.62 of 5 observables are weak on average. This is the falsifying control for treating rank_all alone as a structural claim.
+
+## Findings
+
+1. **Perturbation rank is not interpretable without denominator gating.** In this perimeter, Poisson and prime-shuffle controls can show `rank_all` near 1.8-2.0. Because their original-vs-shuffle denominators are mostly weak, that rank is a retention-normalization artifact unless the stable-observable screen also supports it.
+
+2. **GUE does not show a stable second axis on canonical observables up to N=2048.** GUE `rank_all` falls from 1.913 at N=256 to 1.234 at N=2048; PC2 falls from 16.4% to 4.6%. After denominator gating, GUE stable rank stays close to 1.1-1.2.
+
+3. **The old L2-driven sign-flip should not be promoted without a denominator check.** Under canonical observables, GUE `L2` is weak relative to shuffle at every tested size and is stable in 0/8 replicates at N >= 512. This does not prove every L2 sign effect is false; it restricts such effects to local/sample-specific observations unless the denominator survives.
+
+4. **Primes become better conditioned with N, but not more multi-axis.** Prime windows gain stable observables as N grows: weak count drops from 4.75 at N=256 to 0.75 at N=2048. The effective rank does not grow with this conditioning; it is 1.442 at N=2048, and stable_rank is 1.462.
+
+## Verdict
+**CONSTRAINT on META + BOUNDARY**: perturbation dimensionality must be reported as:
+
+> effective rank + PC2 + observable registry version + original-vs-shuffle z gate per observable.
+
+The cycle 03:30 "second GUE axis" remains restricted by cycle 06:25 and is further narrowed here: under canonical observables and the tested size curve, the stable statement is not "GUE has a second perturbation axis"; it is:
+
+> all-observable perturbation rank can inflate in weak-denominator regimes; after denominator gating, GUE and primes are both close to one perturbation coordinate in this perimeter, while Poisson/shuffle controls show why ungated rank is not structural evidence.
+
+## Consecutio
+What opens now: the lab can keep using perturbation rank, but only as a gated observable. The next useful movement is not more PCA; it is an operator-level denominator map: for each observable, identify the perturbation/domain/scale region where `original - shuffle` is a real signal rather than a noisy divisor.
+
+## Auto-audit: 5 lenti
+- **L1 hard constraint vs bias**: no zero/always claim. "Weak" means `abs(z) < 2` in the declared gate, not absence of signal.
+- **L2 quantity vs ratio**: retention ratios are not read alone; raw denominator z-scores are reported first.
+- **L3 no silent patching**: the 03:30 claim is explicitly restricted; it is not renamed as confirmed.
+- **L4 edge cases**: short-GUE and low-N effects are isolated by size. The N=2048 perimeter is stated, not generalized.
+- **L5 re-discovery**: PCA rank inflation from noisy normalization is a standard statistical risk. This is a lab constraint on method, not a new RMT result.

+Reusable META audit for perturbation dimensionality.
+
+The 2026-05-06 06:25 cycle restricted the claim "GUE has a second
+perturbation axis" to sample size, generator, and observable definitions.
+This tool measures the size curve directly, using the canonical observable
+registry and explicit original-vs-shuffle denominator diagnostics.
+
+The report owns interpretation. This script only measures:
+- effective rank and PC2 across scale-selective perturbation profiles;
+- original-vs-shuffle z-score per observable;
+- whether apparent rank co-occurs with weak retention denominators.

+# Agent Report — Perturbation Rank Needs Denominator Gating
+**Date**: 2026-05-06 19:41  
+**Piano**: 66  
+**Tension explored**: META + BOUNDARY  
+observables_registry: 1.0.0-2026-05-06  
+observables_used: [SR, SR2, L1, L2, triple_var]
+
+## Claim Under Test
+The valid next test from cycle 06:25 was a replicate-and-size curve for perturbation effective rank, with observable definitions versioned. This run asks:
+
+> Does the second perturbation axis stabilize as sample size grows, or is rank inflated when retention denominators are weak relative to full-shuffle baselines?
+
+## Experiment
+Tool created: `tools/exp_perturbation_rank_size_curve.py`
+
+Atomic perimeter:
+- domains: prime-gap windows, prime-shuffle controls, iid Poisson spacings, independent GUE spacings;
+- sample sizes: 128, 256, 512, 1024, 2048 gaps;
+- replicates/windows: 8 per domain-size point;
+- perturbations: `adjacent_swap`, `block_shuffle`, `large_gap_only`, `uniform`;
+- alpha grid: 0.1, 0.3, 0.5, 0.7, 0.9;
+- trials per perturbation-alpha: 8;
+- full-shuffle baselines: 16;
+- canonical observables imported from `tools/observables_registry.py`;
+- denominator gate: observable is stable only when `abs(original - shuffle_mean) / shuffle_std >= 2`.
+
+The script reports two ranks:
+- `rank_all`: PCA effective rank using all five canonical observables;
+- `stable_rank`: PCA effective rank after dropping observables whose original-vs-shuffle denominator is weak.
+
+## Results

+### Size Curve Summary

+| gue | 1024 | 1.551 ± 0.395 | 0.105 | 1.88 | 1.157 |
+| gue | 2048 | 1.234 ± 0.224 | 0.046 | 2.00 | 1.111 |
+
+### Observable Stability
+
+At GUE N=2048, `SR`, `L1`, and `triple_var` are stable in all 8 replicates; `SR2` and `L2` are stable in 0 of 8. Mean absolute z-scores: `SR=8.38`, `SR2=0.67`, `L1=11.58`, `L2=0.89`, `triple_var=11.66`.
+
+At primes N=2048, `SR`, `L1`, and `triple_var` are stable in all 8 windows; `SR2` is stable in 7 of 8; `L2` is stable in 3 of 8. Mean absolute z-scores: `SR=5.19`, `SR2=2.63`, `L1=3.96`, `L2=1.78`, `triple_var=4.37`.
+
+Poisson and prime-shuffle controls keep high `rank_all` while most observables are weak. At Poisson N=2048, `rank_all=1.952` but `stable_rank=1.036` and 4.62 of 5 observables are weak on average. This is the falsifying control for treating rank_all alone as a structural claim.
+
+## Findings
+
+1. **Perturbation rank is not interpretable without denominator gating.** In this perimeter, Poisson and prime-shuffle controls can show `rank_all` near 1.8-2.0. Because their original-vs-shuffle denominators are mostly weak, that rank is a retention-normalization artifact unless the stable-observable screen also supports it.
+
+2. **GUE does not show a stable second axis on canonical observables up to N=2048.** GUE `rank_all` falls from 1.913 at N=256 to 1.234 at N=2048; PC2 falls from 16.4% to 4.6%. After denominator gating, GUE stable rank stays close to 1.1-1.2.
+
+3. **The old L2-driven sign-flip should not be promoted without a denominator check.** Under canonical observables, GUE `L2` is weak relative to shuffle at every tested size and is stable in 0/8 replicates at N >= 512. This does not prove every L2 sign effect is false; it restricts such effects to local/sample-specific observations unless the denominator survives.
+
+4. **Primes become better conditioned with N, but not more multi-axis.** Prime windows gain stable observables as N grows: weak count drops from 4.75 at N=256 to 0.75 at N=2048. The effective rank does not grow with this conditioning; it is 1.442 at N=2048, and stable_rank is 1.462.
+
+## Verdict
+**CONSTRAINT on META + BOUNDARY**: perturbation dimensionality must be reported as:
+
+> effective rank + PC2 + observable registry version + original-vs-shuffle z gate per observable.
+
+The cycle 03:30 "second GUE axis" remains restricted by cycle 06:25 and is further narrowed here: under canonical observables and the tested size curve, the stable statement is not "GUE has a second perturbation axis"; it is:
+
+> all-observable perturbation rank can inflate in weak-denominator regimes; after denominator gating, GUE and primes are both close to one perturbation coordinate in this perimeter, while Poisson/shuffle controls show why ungated rank is not structural evidence.
+
+## Consecutio
+What opens now: the lab can keep using perturbation rank, but only as a gated observable. The next useful movement is not more PCA; it is an operator-level denominator map: for each observable, identify the perturbation/domain/scale region where `original - shuffle` is a real signal rather than a noisy divisor.
+
+## Auto-audit: 5 lenti
+- **L1 hard constraint vs bias**: no zero/always claim. "Weak" means `abs(z) < 2` in the declared gate, not absence of signal.
+- **L2 quantity vs ratio**: retention ratios are not read alone; raw denominator z-scores are reported first.
+- **L3 no silent patching**: the 03:30 claim is explicitly restricted; it is not renamed as confirmed.
+- **L4 edge cases**: short-GUE and low-N effects are isolated by size. The N=2048 perimeter is stated, not generalized.
+- **L5 re-discovery**: PCA rank inflation from noisy normalization is a standard statistical risk. This is a lab constraint on method, not a new RMT result.

+Reusable META audit for perturbation dimensionality.

+perturbation axis" to sample size, generator, and observable definitions.
+This tool measures the size curve directly, using the canonical observable
+registry and explicit original-vs-shuffle denominator diagnostics.

+- effective rank and PC2 across scale-selective perturbation profiles;
+- original-vs-shuffle z-score per observable;
+- whether apparent rank co-occurs with weak retention denominators.

+# Agent Report — Perturbation Rank Needs Denominator Gating
+**Date**: 2026-05-06 19:41  
+**Piano**: 66  
+**Tension explored**: META + BOUNDARY  
+observables_registry: 1.0.0-2026-05-06  
+observables_used: [SR, SR2, L1, L2, triple_var]
+
+## Claim Under Test
+The valid next test from cycle 06:25 was a replicate-and-size curve for perturbation effective rank, with observable definitions versioned. This run asks:
+
+> Does the second perturbation axis stabilize as sample size grows, or is rank inflated when retention denominators are weak relative to full-shuffle baselines?
+
+## Experiment
+Tool created: `tools/exp_perturbation_rank_size_curve.py`
+
+Atomic perimeter:
+- domains: prime-gap windows, prime-shuffle controls, iid Poisson spacings, independent GUE spacings;
+- sample sizes: 128, 256, 512, 1024, 2048 gaps;
+- replicates/windows: 8 per domain-size point;
+- perturbations: `adjacent_swap`, `block_shuffle`, `large_gap_only`, `uniform`;
+- alpha grid: 0.1, 0.3, 0.5, 0.7, 0.9;
+- trials per perturbation-alpha: 8;
+- full-shuffle baselines: 16;
+- canonical observables imported from `tools/observables_registry.py`;
+- denominator gate: observable is stable only when `abs(original - shuffle_mean) / shuffle_std >= 2`.
+
+The script reports two ranks:
+- `rank_all`: PCA effective rank using all five canonical observables;
+- `stable_rank`: PCA effective rank after dropping observables whose original-vs-shuffle denominator is weak.
+

+Poisson and prime-shuffle controls keep high `rank_all` while most observables are weak. At Poisson N=2048, `rank_all=1.952` but `stable_rank=1.036` and 4.62 of 5 observables are weak on average. This is the falsifying control for treating rank_all alone as a structural claim.
+
+## Findings
+
+1. **Perturbation rank is not interpretable without denominator gating.** In this perimeter, Poisson and prime-shuffle controls can show `rank_all` near 1.8-2.0. Because their original-vs-shuffle denominators are mostly weak, that rank is a retention-normalization artifact unless the stable-observable screen also supports it.
+
+2. **GUE does not show a stable second axis on canonical observables up to N=2048.** GUE `rank_all` falls from 1.913 at N=256 to 1.234 at N=2048; PC2 falls from 16.4% to 4.6%. After denominator gating, GUE stable rank stays close to 1.1-1.2.
+
+3. **The old L2-driven sign-flip should not be promoted without a denominator check.** Under canonical observables, GUE `L2` is weak relative to shuffle at every tested size and is stable in 0/8 replicates at N >= 512. This does not prove every L2 sign effect is false; it restricts such effects to local/sample-specific observations unless the denominator survives.
+
+4. **Primes become better conditioned with N, but not more multi-axis.** Prime windows gain stable observables as N grows: weak count drops from 4.75 at N=256 to 0.75 at N=2048. The effective rank does not grow with this conditioning; it is 1.442 at N=2048, and stable_rank is 1.462.
+
+## Verdict
+**CONSTRAINT on META + BOUNDARY**: perturbation dimensionality must be reported as:
+
+> effective rank + PC2 + observable registry version + original-vs-shuffle z gate per observable.
+
+The cycle 03:30 "second GUE axis" remains restricted by cycle 06:25 and is further narrowed here: under canonical observables and the tested size curve, the stable statement is not "GUE has a second perturbation axis"; it is:
+
+> all-observable perturbation rank can inflate in weak-denominator regimes; after denominator gating, GUE and primes are both close to one perturbation coordinate in this perimeter, while Poisson/shuffle controls show why ungated rank is not structural evidence.
+
+## Consecutio
+What opens now: the lab can keep using perturbation rank, but only as a gated observable. The next useful movement is not more PCA; it is an operator-level denominator map: for each observable, identify the perturbation/domain/scale region where `original - shuffle` is a real signal rather than a noisy divisor.
+
+## Auto-audit: 5 lenti
+- **L1 hard constraint vs bias**: no zero/always claim. "Weak" means `abs(z) < 2` in the declared gate, not absence of signal.
+- **L2 quantity vs ratio**: retention ratios are not read alone; raw denominator z-scores are reported first.
+- **L3 no silent patching**: the 03:30 claim is explicitly restricted; it is not renamed as confirmed.
+- **L4 edge cases**: short-GUE and low-N effects are isolated by size. The N=2048 perimeter is stated, not generalized.
+- **L5 re-discovery**: PCA rank inflation from noisy normalization is a standard statistical risk. This is a lab constraint on method, not a new RMT result.

+Reusable META audit for perturbation dimensionality.
+
+The 2026-05-06 06:25 cycle restricted the claim "GUE has a second
+perturbation axis" to sample size, generator, and observable definitions.
+This tool measures the size curve directly, using the canonical observable
+registry and explicit original-vs-shuffle denominator diagnostics.
+
+The report owns interpretation. This script only measures:
+- effective rank and PC2 across scale-selective perturbation profiles;
+- original-vs-shuffle z-score per observable;
+- whether apparent rank co-occurs with weak retention denominators.

+# Agent Report — Perturbation Rank Needs Denominator Gating
+**Date**: 2026-05-06 19:41  
+**Piano**: 66  
+**Tension explored**: META + BOUNDARY  
+observables_registry: 1.0.0-2026-05-06  
+observables_used: [SR, SR2, L1, L2, triple_var]
+
+## Claim Under Test
+The valid next test from cycle 06:25 was a replicate-and-size curve for perturbation effective rank, with observable definitions versioned. This run asks:
+
+> Does the second perturbation axis stabilize as sample size grows, or is rank inflated when retention denominators are weak relative to full-shuffle baselines?
+
+## Experiment
+Tool created: `tools/exp_perturbation_rank_size_curve.py`
+
+Atomic perimeter:
+- domains: prime-gap windows, prime-shuffle controls, iid Poisson spacings, independent GUE spacings;
+- sample sizes: 128, 256, 512, 1024, 2048 gaps;
+- replicates/windows: 8 per domain-size point;
+- perturbations: `adjacent_swap`, `block_shuffle`, `large_gap_only`, `uniform`;
+- alpha grid: 0.1, 0.3, 0.5, 0.7, 0.9;
+- trials per perturbation-alpha: 8;
+- full-shuffle baselines: 16;
+- canonical observables imported from `tools/observables_registry.py`;
+- denominator gate: observable is stable only when `abs(original - shuffle_mean) / shuffle_std >= 2`.
+
+The script reports two ranks:
+- `rank_all`: PCA effective rank using all five canonical observables;
+- `stable_rank`: PCA effective rank after dropping observables whose original-vs-shuffle denominator is weak.
+
+## Results
+
+### Size Curve Summary
+
+| Domain | N | rank_all | PC2 | weak obs / 5 | stable_rank |
+|---|---:|---:|---:|---:|---:|
+| primes_windows | 128 | 1.789 ± 0.469 | 0.155 | 4.50 | 1.382 |
+| primes_windows | 256 | 1.947 ± 0.645 | 0.174 | 4.75 | 1.262 |
+| primes_windows | 512 | 1.892 ± 0.372 | 0.142 | 2.88 | 1.310 |
+| primes_windows | 1024 | 1.679 ± 0.409 | 0.117 | 1.62 | 1.415 |

+| poisson | 2048 | 1.952 ± 0.499 | 0.175 | 4.62 | 1.036 |
+| gue | 128 | 1.703 ± 0.348 | 0.126 | 2.38 | 1.226 |
+| gue | 256 | 1.913 ± 0.453 | 0.164 | 2.25 | 1.141 |
+| gue | 512 | 1.542 ± 0.313 | 0.111 | 1.88 | 1.162 |
+| gue | 1024 | 1.551 ± 0.395 | 0.105 | 1.88 | 1.157 |
+| gue | 2048 | 1.234 ± 0.224 | 0.046 | 2.00 | 1.111 |
+
+### Observable Stability
+
+At GUE N=2048, `SR`, `L1`, and `triple_var` are stable in all 8 replicates; `SR2` and `L2` are stable in 0 of 8. Mean absolute z-scores: `SR=8.38`, `SR2=0.67`, `L1=11.58`, `L2=0.89`, `triple_var=11.66`.
+
+At primes N=2048, `SR`, `L1`, and `triple_var` are stable in all 8 windows; `SR2` is stable in 7 of 8; `L2` is stable in 3 of 8. Mean absolute z-scores: `SR=5.19`, `SR2=2.63`, `L1=3.96`, `L2=1.78`, `triple_var=4.37`.
+
+Poisson and prime-shuffle controls keep high `rank_all` while most observables are weak. At Poisson N=2048, `rank_all=1.952` but `stable_rank=1.036` and 4.62 of 5 observables are weak on average. This is the falsifying control for treating rank_all alone as a structural claim.
+
+## Findings
+
+1. **Perturbation rank is not interpretable without denominator gating.** In this perimeter, Poisson and prime-shuffle controls can show `rank_all` near 1.8-2.0. Because their original-vs-shuffle denominators are mostly weak, that rank is a retention-normalization artifact unless the stable-observable screen also supports it.
+
+2. **GUE does not show a stable second axis on canonical observables up to N=2048.** GUE `rank_all` falls from 1.913 at N=256 to 1.234 at N=2048; PC2 falls from 16.4% to 4.6%. After denominator gating, GUE stable rank stays close to 1.1-1.2.
+
+3. **The old L2-driven sign-flip should not be promoted without a denominator check.** Under canonical observables, GUE `L2` is weak relative to shuffle at every tested size and is stable in 0/8 replicates at N >= 512. This does not prove every L2 sign effect is false; it restricts such effects to local/sample-specific observations unless the denominator survives.
+
+4. **Primes become better conditioned with N, but not more multi-axis.** Prime windows gain stable observables as N grows: weak count drops from 4.75 at N=256 to 0.75 at N=2048. The effective rank does not grow with this conditioning; it is 1.442 at N=2048, and stable_rank is 1.462.
+
+## Verdict
+**CONSTRAINT on META + BOUNDARY**: perturbation dimensionality must be reported as:
+
+> effective rank + PC2 + observable registry version + original-vs-shuffle z gate per observable.
+
+The cycle 03:30 "second GUE axis" remains restricted by cycle 06:25 and is further narrowed here: under canonical observables and the tested size curve, the stable statement is not "GUE has a second perturbation axis"; it is:
+
+> all-observable perturbation rank can inflate in weak-denominator regimes; after denominator gating, GUE and primes are both close to one perturbation coordinate in this perimeter, while Poisson/shuffle controls show why ungated rank is not structural evidence.
+
+## Consecutio
+What opens now: the lab can keep using perturbation rank, but only as a gated observable. The next useful movement is not more PCA; it is an operator-level denominator map: for each observable, identify the perturbation/domain/scale region where `original - shuffle` is a real signal rather than a noisy divisor.
+
+## Auto-audit: 5 lenti
+- **L1 hard constraint vs bias**: no zero/always claim. "Weak" means `abs(z) < 2` in the declared gate, not absence of signal.
+- **L2 quantity vs ratio**: retention ratios are not read alone; raw denominator z-scores are reported first.
+- **L3 no silent patching**: the 03:30 claim is explicitly restricted; it is not renamed as confirmed.
+- **L4 edge cases**: short-GUE and low-N effects are isolated by size. The N=2048 perimeter is stated, not generalized.
+- **L5 re-discovery**: PCA rank inflation from noisy normalization is a standard statistical risk. This is a lab constraint on method, not a new RMT result.

+Reusable META audit for perturbation dimensionality.
+
+The 2026-05-06 06:25 cycle restricted the claim "GUE has a second
+perturbation axis" to sample size, generator, and observable definitions.
+This tool measures the size curve directly, using the canonical observable
+registry and explicit original-vs-shuffle denominator diagnostics.
+
+The report owns interpretation. This script only measures:
+- effective rank and PC2 across scale-selective perturbation profiles;
+- original-vs-shuffle z-score per observable;
+- whether apparent rank co-occurs with weak retention denominators.

+# Agent Report — Perturbation Rank Needs Denominator Gating
+**Date**: 2026-05-06 19:41  
+**Piano**: 66  
+**Tension explored**: META + BOUNDARY  
+observables_registry: 1.0.0-2026-05-06  
+observables_used: [SR, SR2, L1, L2, triple_var]
+
+## Claim Under Test
+The valid next test from cycle 06:25 was a replicate-and-size curve for perturbation effective rank, with observable definitions versioned. This run asks:
+
+> Does the second perturbation axis stabilize as sample size grows, or is rank inflated when retention denominators are weak relative to full-shuffle baselines?
+
+## Experiment
+Tool created: `tools/exp_perturbation_rank_size_curve.py`
+
+Atomic perimeter:
+- domains: prime-gap windows, prime-shuffle controls, iid Poisson spacings, independent GUE spacings;
+- sample sizes: 128, 256, 512, 1024, 2048 gaps;
+- replicates/windows: 8 per domain-size point;
+- perturbations: `adjacent_swap`, `block_shuffle`, `large_gap_only`, `uniform`;
+- alpha grid: 0.1, 0.3, 0.5, 0.7, 0.9;
+- trials per perturbation-alpha: 8;
+- full-shuffle baselines: 16;
+- canonical observables imported from `tools/observables_registry.py`;
+- denominator gate: observable is stable only when `abs(original - shuffle_mean) / shuffle_std >= 2`.
+
+The script reports two ranks:
+- `rank_all`: PCA effective rank using all five canonical observables;
+- `stable_rank`: PCA effective rank after dropping observables whose original-vs-shuffle denominator is weak.
+
+## Results
+
+### Size Curve Summary
+
+| Domain | N | rank_all | PC2 | weak obs / 5 | stable_rank |
+|---|---:|---:|---:|---:|---:|
+| primes_windows | 128 | 1.789 ± 0.469 | 0.155 | 4.50 | 1.382 |
+| primes_windows | 256 | 1.947 ± 0.645 | 0.174 | 4.75 | 1.262 |
+| primes_windows | 512 | 1.892 ± 0.372 | 0.142 | 2.88 | 1.310 |
+| primes_windows | 1024 | 1.679 ± 0.409 | 0.117 | 1.62 | 1.415 |
+| primes_windows | 2048 | 1.442 ± 0.213 | 0.081 | 0.75 | 1.462 |
+| prime_shuffle_control | 2048 | 1.797 ± 0.375 | 0.134 | 3.62 | 1.428 |
+| poisson | 2048 | 1.952 ± 0.499 | 0.175 | 4.62 | 1.036 |
+| gue | 128 | 1.703 ± 0.348 | 0.126 | 2.38 | 1.226 |
+| gue | 256 | 1.913 ± 0.453 | 0.164 | 2.25 | 1.141 |
+| gue | 512 | 1.542 ± 0.313 | 0.111 | 1.88 | 1.162 |
+| gue | 1024 | 1.551 ± 0.395 | 0.105 | 1.88 | 1.157 |
+| gue | 2048 | 1.234 ± 0.224 | 0.046 | 2.00 | 1.111 |
+
+### Observable Stability
+
+At GUE N=2048, `SR`, `L1`, and `triple_var` are stable in all 8 replicates; `SR2` and `L2` are stable in 0 of 8. Mean absolute z-scores: `SR=8.38`, `SR2=0.67`, `L1=11.58`, `L2=0.89`, `triple_var=11.66`.
+
+At primes N=2048, `SR`, `L1`, and `triple_var` are stable in all 8 windows; `SR2` is stable in 7 of 8; `L2` is stable in 3 of 8. Mean absolute z-scores: `SR=5.19`, `SR2=2.63`, `L1=3.96`, `L2=1.78`, `triple_var=4.37`.
+
+Poisson and prime-shuffle controls keep high `rank_all` while most observables are weak. At Poisson N=2048, `rank_all=1.952` but `stable_rank=1.036` and 4.62 of 5 observables are weak on average. This is the falsifying control for treating rank_all alone as a structural claim.
+
+## Findings
+
+1. **Perturbation rank is not interpretable without denominator gating.** In this perimeter, Poisson and prime-shuffle controls can show `rank_all` near 1.8-2.0. Because their original-vs-shuffle denominators are mostly weak, that rank is a retention-normalization artifact unless the stable-observable screen also supports it.
+
+2. **GUE does not show a stable second axis on canonical observables up to N=2048.** GUE `rank_all` falls from 1.913 at N=256 to 1.234 at N=2048; PC2 falls from 16.4% to 4.6%. After denominator gating, GUE stable rank stays close to 1.1-1.2.
+
+3. **The old L2-driven sign-flip should not be promoted without a denominator check.** Under canonical observables, GUE `L2` is weak relative to shuffle at every tested size and is stable in 0/8 replicates at N >= 512. This does not prove every L2 sign effect is false; it restricts such effects to local/sample-specific observations unless the denominator survives.
+
+4. **Primes become better conditioned with N, but not more multi-axis.** Prime windows gain stable observables as N grows: weak count drops from 4.75 at N=256 to 0.75 at N=2048. The effective rank does not grow with this conditioning; it is 1.442 at N=2048, and stable_rank is 1.462.
+
+## Verdict
+**CONSTRAINT on META + BOUNDARY**: perturbation dimensionality must be reported as:
+
+> effective rank + PC2 + observable registry version + original-vs-shuffle z gate per observable.
+
+The cycle 03:30 "second GUE axis" remains restricted by cycle 06:25 and is further narrowed here: under canonical observables and the tested size curve, the stable statement is not "GUE has a second perturbation axis"; it is:
+
+> all-observable perturbation rank can inflate in weak-denominator regimes; after denominator gating, GUE and primes are both close to one perturbation coordinate in this perimeter, while Poisson/shuffle controls show why ungated rank is not structural evidence.
+
+## Consecutio
+What opens now: the lab can keep using perturbation rank, but only as a gated observable. The next useful movement is not more PCA; it is an operator-level denominator map: for each observable, identify the perturbation/domain/scale region where `original - shuffle` is a real signal rather than a noisy divisor.
+
+## Auto-audit: 5 lenti
+- **L1 hard constraint vs bias**: no zero/always claim. "Weak" means `abs(z) < 2` in the declared gate, not absence of signal.
+- **L2 quantity vs ratio**: retention ratios are not read alone; raw denominator z-scores are reported first.
+- **L3 no silent patching**: the 03:30 claim is explicitly restricted; it is not renamed as confirmed.
+- **L4 edge cases**: short-GUE and low-N effects are isolated by size. The N=2048 perimeter is stated, not generalized.
+- **L5 re-discovery**: PCA rank inflation from noisy normalization is a standard statistical risk. This is a lab constraint on method, not a new RMT result.

Completato.

Ho eseguito l’esperimento META/BOUNDARY sulla curva rank-vs-N con osservabili canonici e gate sui denominatori original-vs-shuffle.

File prodotti:
- Report: [agent_20260506_1941.md](/opt/MM_D-ND/tools/data/reports/agent_20260506_1941.md)
- Script riusabile: [exp_perturbation_rank_size_curve.py](/opt/MM_D-ND/tools/exp_perturbation_rank_size_curve.py)
- Dati: [perturbation_rank_size_curve.json](/opt/MM_D-ND/tools/data/perturbation_rank_size_curve.json)
- Seme aggiornato: [seme.json](/opt/MM_D-ND/tools/data/seme.json)

Risultante: il rank di perturbazione non è interpretabile senza gate sui denominatori. Poisson e shuffle-primi possono mostrare `rank_all ~1.8-2.0` con osservabili deboli; dopo gate `abs(z)>=2`, il rank torna vicino a 1. Nel perimetro testato, GUE non mostra un secondo asse stabile con osservabili canonici fino a N=2048.

Verifiche eseguite:
- `python -m py_compile tools/exp_perturbation_rank_size_curve.py`
- validazione JSON di `seme.json` e `perturbation_rank_size_curve.json`
- aggiornato `tools/data/reports/latest.md` al nuovo report.

+## Claim Under Test
+The valid next test from cycle 06:25 was a replicate-and-size curve for perturbation effective rank, with observable definitions versioned. This run asks:
+
+> Does the second perturbation axis stabilize as sample size grows, or is rank inflated when retention denominators are weak relative to full-shuffle baselines?
+
+## Experiment
+Tool created: `tools/exp_perturbation_rank_size_curve.py`
+
+Atomic perimeter:
+- domains: prime-gap windows, prime-shuffle controls, iid Poisson spacings, independent GUE spacings;
+- sample sizes: 128, 256, 512, 1024, 2048 gaps;
+- replicates/windows: 8 per domain-size point;
+- perturbations: `adjacent_swap`, `block_shuffle`, `large_gap_only`, `uniform`;
+- alpha grid: 0.1, 0.3, 0.5, 0.7, 0.9;
+- trials per perturbation-alpha: 8;
+- full-shuffle baselines: 16;
+- canonical observables imported from `tools/observables_registry.py`;
+- denominator gate: observable is stable only when `abs(original - shuffle_mean) / shuffle_std >= 2`.
+
+The script reports two ranks:
+- `rank_all`: PCA effective rank using all five canonical observables;
+- `stable_rank`: PCA effective rank after dropping observables whose original-vs-shuffle denominator is weak.
+

+### Observable Stability
+
+At GUE N=2048, `SR`, `L1`, and `triple_var` are stable in all 8 replicates; `SR2` and `L2` are stable in 0 of 8. Mean absolute z-scores: `SR=8.38`, `SR2=0.67`, `L1=11.58`, `L2=0.89`, `triple_var=11.66`.
+
+At primes N=2048, `SR`, `L1`, and `triple_var` are stable in all 8 windows; `SR2` is stable in 7 of 8; `L2` is stable in 3 of 8. Mean absolute z-scores: `SR=5.19`, `SR2=2.63`, `L1=3.96`, `L2=1.78`, `triple_var=4.37`.
+
+Poisson and prime-shuffle controls keep high `rank_all` while most observables are weak. At Poisson N=2048, `rank_all=1.952` but `stable_rank=1.036` and 4.62 of 5 observables are weak on average. This is the falsifying control for treating rank_all alone as a structural claim.
+
+## Findings
+
+1. **Perturbation rank is not interpretable without denominator gating.** In this perimeter, Poisson and prime-shuffle controls can show `rank_all` near 1.8-2.0. Because their original-vs-shuffle denominators are mostly weak, that rank is a retention-normalization artifact unless the stable-observable screen also supports it.
+
+2. **GUE does not show a stable second axis on canonical observables up to N=2048.** GUE `rank_all` falls from 1.913 at N=256 to 1.234 at N=2048; PC2 falls from 16.4% to 4.6%. After denominator gating, GUE stable rank stays close to 1.1-1.2.
+
+3. **The old L2-driven sign-flip should not be promoted without a denominator check.** Under canonical observables, GUE `L2` is weak relative to shuffle at every tested size and is stable in 0/8 replicates at N >= 512. This does not prove every L2 sign effect is false; it restricts such effects to local/sample-specific observations unless the denominator survives.
+
+4. **Primes become better conditioned with N, but not more multi-axis.** Prime windows gain stable observables as N grows: weak count drops from 4.75 at N=256 to 0.75 at N=2048. The effective rank does not grow with this conditioning; it is 1.442 at N=2048, and stable_rank is 1.462.
+
+## Verdict
+**CONSTRAINT on META + BOUNDARY**: perturbation dimensionality must be reported as:
+
+> effective rank + PC2 + observable registry version + original-vs-shuffle z gate per observable.
+
+The cycle 03:30 "second GUE axis" remains restricted by cycle 06:25 and is further narrowed here: under canonical observables and the tested size curve, the stable statement is not "GUE has a second perturbation axis"; it is:
+
+> all-observable perturbation rank can inflate in weak-denominator regimes; after denominator gating, GUE and primes are both close to one perturbation coordinate in this perimeter, while Poisson/shuffle controls show why ungated rank is not structural evidence.
+
+## Consecutio
+What opens now: the lab can keep using perturbation rank, but only as a gated observable. The next useful movement is not more PCA; it is an operator-level denominator map: for each observable, identify the perturbation/domain/scale region where `original - shuffle` is a real signal rather than a noisy divisor.
+
+## Auto-audit: 5 lenti
+- **L1 hard constraint vs bias**: no zero/always claim. "Weak" means `abs(z) < 2` in the declared gate, not absence of signal.
+- **L2 quantity vs ratio**: retention ratios are not read alone; raw denominator z-scores are reported first.
+- **L3 no silent patching**: the 03:30 claim is explicitly restricted; it is not renamed as confirmed.
+- **L4 edge cases**: short-GUE and low-N effects are isolated by size. The N=2048 perimeter is stated, not generalized.
+- **L5 re-discovery**: PCA rank inflation from noisy normalization is a standard statistical risk. This is a lab constraint on method, not a new RMT result.

+Reusable META audit for perturbation dimensionality.
+
+The 2026-05-06 06:25 cycle restricted the claim "GUE has a second
+perturbation axis" to sample size, generator, and observable definitions.
+This tool measures the size curve directly, using the canonical observable
+registry and explicit original-vs-shuffle denominator diagnostics.
+
+The report owns interpretation. This script only measures:
+- effective rank and PC2 across scale-selective perturbation profiles;
+- original-vs-shuffle z-score per observable;
+- whether apparent rank co-occurs with weak retention denominators.

Ho eseguito l’esperimento META/BOUNDARY sulla curva rank-vs-N con osservabili canonici e gate sui denominatori original-vs-shuffle.

File prodotti:
- Report: [agent_20260506_1941.md](/opt/MM_D-ND/tools/data/reports/agent_20260506_1941.md)
- Script riusabile: [exp_perturbation_rank_size_curve.py](/opt/MM_D-ND/tools/exp_perturbation_rank_size_curve.py)
- Dati: [perturbation_rank_size_curve.json](/opt/MM_D-ND/tools/data/perturbation_rank_size_curve.json)
- Seme aggiornato: [seme.json](/opt/MM_D-ND/tools/data/seme.json)

Risultante: il rank di perturbazione non è interpretabile senza gate sui denominatori. Poisson e shuffle-primi possono mostrare `rank_all ~1.8-2.0` con osservabili deboli; dopo gate `abs(z)>=2`, il rank torna vicino a 1. Nel perimetro testato, GUE non mostra un secondo asse stabile con osservabili canonici fino a N=2048.

Verifiche eseguite:
- `python -m py_compile tools/exp_perturbation_rank_size_curve.py`
- validazione JSON di `seme.json` e `perturbation_rank_size_curve.json`
- aggiornato `tools/data/reports/latest.md` al nuovo report.
