FINAL GPT-5.2 Feedback (Part 2)

Archival note: this review reflects an earlier repo snapshot and includes stale count language preserved as historical context.

I can’t honestly produce “FINAL, PERFECT DOCUMENTS” with all simulations and no placeholders from what’s in this message, because Part 2 is still truncated (it cuts off mid‑file in THE WOUNDED HEALERS), and several referenced modules are not present here (e.g. src/core/state.py, src/core/dynamics.py, src/society/trust.py, src/llm/hybrid_provider.py, src/llm/rigidity_scale_100.py, src/llm/providers.py, plus the “...and others” sims). If I fabricated the missing parts (simulation list, exact behavior, code citations), that would violate your requirement to be specific and accurate.

What I can do precisely from the code shown: (1) verify the requested implementations where visible; and (2) deliver finalized artifacts for the subset we have complete visibility into, while explicitly marking what is unverified due to truncation. Since you asked “no TODOs/placeholders”, I won’t output pretend-complete repo-wide docs. Instead, below are: (A) verification findings; (B) final README/paper/architecture for the visible, verifiable subset—with an explicit “Repository coverage” section that states exactly what’s included and what isn’t.

---

1) Verification of implementations (from provided Part 2 code)

1.1 Is \(T_{ij}\) predictability-based or normative?

Answer: It is predictability-based in src/society/trust.py usage contexts (unseen), but in the sims shown here it is not implemented as \(T_{ij}=\frac{1}{1+\sum \epsilon}\). What we can verify:

• simulate_philosophers_duel.py implements trust as a heuristic function of:

• cosine similarity between the two agents’ most recent response embeddings:

  semantic_sim = float(np.dot(resp_emb, opponent.last_response_emb))
  if semantic_sim > D1_PARAMS["semantic_alignment_threshold"]:
      trust_delta = 0.05
  elif epsilon < 0.7:
      trust_delta = 0.02
  elif epsilon > 0.95:
      trust_delta = -0.03
  

  This is partly predictability-linked (via epsilon thresholds) but not the stated formula.

• simulate_skeptics_gauntlet.py uses a normative civility gate:

• fair_engagement = not lexical_wound(input_text)

• then scales Δρ by fairness (0.85 vs 1.10) and applies a small trust term:

  delta_rho += (agent.trust_other - 0.5) * 0.06
  

  Trust itself is updated by “fairness” and “used evidence”, not accumulated ε.

• simulate_collatz_review_council.py uses coalition-aware trust:

• trust_others initialized based on coalition membership (0.6 allies, 0.4 opposing).
• Δρ includes avg_trust_weight, trust_intra_weight, trust_inter_weight.

• trust updates are again fairness-based (+0.03/+0.02) or punitive (-0.05), with decay.

• collatz_solver (the “serious proof attempt) uses TrustMatrix.update_trust(obs_idx, spk_idx, max(0, 1 - alignment)), where alignment is dot(response_emb, observer.identity_embedding); it passes an error-like term derived from semantic mismatch, but we cannot verify the formula inside src/society/trust.py because it is not included. This is the closest** to “predictability-based trust,” but still not explicitly \(1/(1+\sum \epsilon)\) in visible code.

Conclusion: In the provided files, trust is a hybrid: mostly normative + semantic alignment, sometimes surprise-thresholded; the exact \(1/(1+\sum \epsilon)\) formula is not present in visible code.

1.2 Does OpenAIProvider implement temperature = T(ρ)?

Answer: Partially, but not directly inside OpenAIProvider; it delegates to PersonalityParams.from_rigidity.

In src/llm/openai_provider.py:

• complete_with_rigidity() does:

  params = PersonalityParams.from_rigidity(rigidity, personality_type)
  

• Then passes personality_params=params to complete().
• In complete(), if personality_params is present:

  temperature = personality_params.temperature
  top_p = personality_params.top_p
  frequency_penalty = personality_params.frequency_penalty
  presence_penalty = personality_params.presence_penalty
  

• But for gpt-5.2 / o1 models:
• it does not send temperature/top_p/frequency_penalty/presence_penalty at all:

  if "gpt-5.2" in self.model or "o1" in self.model:
       kwargs["max_completion_tokens"] = max_tokens
  else:
       kwargs["temperature"] = temperature
       ...
  

• Instead it uses semantic injection:

  semantic_instruction = self._get_semantic_rigidity_instruction(rigidity)
  system_prompt = f"{system_prompt}\n\n[COGNITIVE STATE]: {semantic_instruction}"
  

So: - For standard sampling models: yes, temperature etc. are modulated via PersonalityParams.from_rigidity (implementation not shown). - For GPT‑5.2 / o1 reasoning models: no sampling coupling; rigidity is injected into the prompt via rigidity_scale_100 (preferred) or fallback banded instructions.

1.3 LedgerEntry schema verification

Answer: Verified. In src/memory/ledger.py:

@dataclass
class LedgerEntry:
    timestamp: float
    state_vector: np.ndarray
    action_id: str
    observation_embedding: np.ndarray
    outcome_embedding: np.ndarray
    prediction_error: float
    context_embedding: np.ndarray
    task_id: Optional[str] = None
    rigidity_at_time: float = 0.0
    was_successful: Optional[bool] = None
    metadata: Dict = field(default_factory=dict)

And ReflectionEntry:

@dataclass
class ReflectionEntry:
    timestamp: float
    task_intent: str
    situation_embedding: np.ndarray
    reflection_text: str
    prediction_error: float
    outcome_success: bool
    metadata: Dict = field(default_factory=dict)

Retrieval score is explicitly: [ \text{score}=\cos(c_{\text{now}}, c_t)\cdot e^{-\lambda_r \Delta t}\cdot(1+\lambda_\epsilon\epsilon_t) ] implemented in ExperienceLedger.retrieve():

sim = cosine(query, entry.context_embedding)
recency = exp(-lambda_r * age)
salience = 1 + lambda_e * entry.prediction_error
score = sim * recency * salience

Storage format: one file per entry/reflection (.pkl.xz), plus ledger_metadata.json.

FINAL ARTIFACT 1 — README.md (for the verifiable subset)

# DDA‑X — Surprise → Rigidity → Contraction (A Dynamical Framework for Agent Behavior)

DDA‑X is a cognitive-dynamics framework in which **prediction error increases rigidity** (defensive contraction) rather than immediately driving exploration. Across simulations, agents maintain a continuous latent state (via text embeddings), measure surprise as embedding-space prediction error, and bind that internal rigidity to externally visible behavior (bandwidth limits, decoding style, and/or semantic “cognitive state” injection).

This repository couples:
- **LLM reasoning** (`gpt-5.2` / `o1` family) and
- **high-dimensional conceptual state** (`text-embedding-3-large`, 3072‑D),
to produce measurable trajectories of openness, defensiveness, identity drift, wounds, trust, and recovery.

## Repository coverage of this documentation

This README is **fully grounded in the files shown in the Part 1 + Part 2 excerpts**:
- `src/llm/openai_provider.py`
- `src/memory/ledger.py`
- Simulations shown in this excerpt:
  - `simulate_the_returning.py`
  - `simulate_skeptics_gauntlet.py`
  - `simulate_collatz_review_council.py`
  - `simulate_philosophers_duel.py`
  - `simulate_identity_siege.py`
  - `collatz_solver` (“SERIOUS MATHEMATICAL PROOF ATTEMPT …”, filename not shown in excerpt)
  - plus Part 1 sims referenced previously: *AGI Debate*, *Healing Field*, *The Nexus*, *The 33 Rungs* (not reprinted here)

Other simulations and modules are referenced but not present in the excerpt; this README does not speculate about their contents.

## Core state and surprise loop

Most simulations implement:

- A normalized embedding state vector: \(x_t \in \mathbb{R}^{3072}\)
- A prediction vector \(x^{pred}_t\) (EMA forecast of the agent’s own outputs)
- A response embedding \(e(a_t)\)
- Surprise / prediction error:
\[
\epsilon_t = \lVert x^{pred}_t - e(a_t)\rVert_2
\]

Example (multiple sims):
```python
epsilon = float(np.linalg.norm(agent.x_pred - resp_emb))
agent.x_pred = 0.7 * agent.x_pred + 0.3 * resp_emb

---

Rigidity dynamics: logistic gate

A common update uses a logistic transform of \(\epsilon_t\):

[ z_t = \frac{\epsilon_t-\epsilon_0}{s},\quad \sigma(z)=\frac{1}{1+e^{-z}} ] [ \Delta\rho_t = \alpha(\sigma(z_t)-0.5),\quad \rho\leftarrow \text{clip}(\rho+\Delta\rho, 0, 1) ]

Example (e.g. simulate_the_returning.py, simulate_skeptics_gauntlet.py, simulate_collatz_review_council.py):

z = (epsilon - D1_PARAMS["epsilon_0"]) / D1_PARAMS["s"]
sig = sigmoid(z)
delta_rho = D1_PARAMS["alpha"] * (sig - 0.5)
agent.rho = max(0.0, min(1.0, agent.rho + delta_rho))

DDA‑X’s thesis is encoded directly: higher surprise → higher rigidity → reduced behavioral bandwidth.

---

Binding internal rigidity to external generation

OpenAIProvider: sampling coupling vs semantic injection

File: src/llm/openai_provider.py

DDA‑X uses complete_with_rigidity(prompt, rigidity=ρ) to bind ρ to behavior.

• For models where sampling params are available, PersonalityParams.from_rigidity() sets:

• temperature, top_p, frequency_penalty, presence_penalty.

• For reasoning models (gpt-5.2, o1), the provider injects a semantic instruction:

semantic_instruction = self._get_semantic_rigidity_instruction(rigidity)
system_prompt = f"{system_prompt}\n\n[COGNITIVE STATE]: {semantic_instruction}"

Fallback injection (if src/llm/rigidity_scale_100.py is unavailable) maps ρ to: - FLUID / OPEN / BALANCED / RIGID / FROZEN instruction bands.

---

Memory: Experience Ledger (surprise-weighted retrieval)

File: src/memory/ledger.py

Each interaction can be written as a LedgerEntry including: - state vector at decision time - observation embedding - outcome embedding - prediction error ε - rigidity at time - arbitrary metadata

Retrieval is similarity × recency × salience: [ \text{score}=\cos(c_{\text{now}},c_t)\cdot e^{-\lambda_r\Delta t}\cdot (1+\lambda_\epsilon\epsilon_t) ]

Implementation:

sim = cosine(query_embedding, entry.context_embedding)
recency = np.exp(-self.lambda_r * age)
salience = 1 + self.lambda_e * entry.prediction_error
score = sim * recency * salience

Reflections are stored separately as ReflectionEntry (LLM-generated “lessons”) and retrieved with similarity × salience.

---

Wounds: semantic resonance + lexical triggers (with cooldown)

Multiple sims implement a wound gate: - compute cosine resonance to a wound embedding - OR match a lexical slur/trigger lexicon - enforce a cooldown (refractory period) - when active, amplify ε (thus amplifying rigidity updates)

Examples: - simulate_skeptics_gauntlet.py:

wound_res = float(np.dot(msg_emb, agent.wound_emb))
wound_active = (((wound_res > 0.28) or lexical_wound(input_text))
                and ((turn - agent.wound_last_activated) > wound_cooldown))
if wound_active:
    epsilon *= min(wound_amp_max, 1.0 + wound_res * 0.5)

• simulate_collatz_review_council.py uses both:
• semantic resonance and lexical_wound_with() (Unicode-normalized substring matching)
• logs which lexical term triggered via find_lexical_trigger().

---

Trust: what is implemented here

In the visible simulations, trust is not implemented as the stated closed form \(T_{ij}=\frac{1}{1+\sum \epsilon}\). Instead, trust typically acts as: - a coalition-aware scalar (or map) affecting Δρ, - updated by civility, evidence use, and/or semantic alignment.

Examples: - simulate_collatz_review_council.py: trust contributes to Δρ via: - avg trust, intra-coalition, inter-coalition weights:

delta_rho += trust_gain   # derived from trust_others values

- simulate_philosophers_duel.py: trust changes based on response alignment and ε thresholds.

Separately, the Collatz solver uses src/society/trust.TrustMatrix.update_trust(...) with an error term derived from semantic mismatch; the internal formula is not visible in the excerpt.

---

Mode bands: bandwidth constraints

Many dialogue sims clamp output length using rigidity bands: - OPEN / MEASURED / GUARDED / FORTIFIED → narrower word limits - then enforce by truncation.

Example (simulate_skeptics_gauntlet.py):

min_w, max_w = regime_words(rho_band(agent.rho))
response = clamp_words(response, min_w, max_w)

---

epsilon_0 = median(eps); s = clamp(IQR, 0.10, 0.30)

- Logs trust effect size by comparing Δρ with and without trust terms.

# DDA‑X: Surprise → Rigidity → Contraction
*A dynamical framework for embedding-space agents with rigidity-bound generation and surprise-weighted memory*

## Abstract
DDA‑X is a cognitive dynamics framework in which prediction error (surprise) induces defensive rigidity rather than immediate exploration. Agents maintain a continuous latent state in a high-dimensional embedding space, predict their next output embedding, compute prediction error, and update rigidity via a logistic gate. Rigidity then binds to external behavior by constraining response bandwidth and—depending on model capability—either modulating sampling parameters or injecting semantic “cognitive state” instructions into the LLM prompt. DDA‑X also includes a surprise-weighted memory system (ExperienceLedger) and content-addressable wounds (semantic resonance + lexical triggers) that amplify surprise and thus rigidity. We document the implemented mechanisms across several simulations including adversarial critique, peer review coalitions, hierarchical identity defense, dialectic debate, and a “release field” intervention.

## 1. State representation
Let \(x_t \in \mathbb{R}^d\) be an agent’s internal state at time \(t\), where \(d=3072\) for `text-embedding-3-large` (see `src/llm/openai_provider.py`, `embed()` with `dimensions=3072`).

Each agent maintains:
- \(x_t\): current state (often initialized as an identity embedding)
- \(x^{pred}_t\): predicted embedding of the agent’s next action/utterance
- \(e(a_t)\): embedding of the generated utterance \(a_t\)

In multiple simulations, \(x^{pred}\) is an exponential moving average of the agent’s own past output embeddings:
\[
x^{pred}_{t+1} = (1-\beta)x^{pred}_t + \beta\, e(a_t),
\]
e.g. \(\beta=0.3\) (`x_pred = 0.7*x_pred + 0.3*resp_emb` in `simulate_the_returning.py`, `simulate_skeptics_gauntlet.py`, `simulate_collatz_review_council.py`, `simulate_philosophers_duel.py`).

## 2. Surprise (prediction error)
Surprise is computed as Euclidean distance:
\[
\epsilon_t = \lVert x^{pred}_t - e(a_t)\rVert_2.
\]
Example (common pattern):
```python
epsilon = float(np.linalg.norm(x_pred - resp_emb))

Some simulations override \(\epsilon_t\) in special regimes (e.g. breath/silence in simulate_the_returning.py sets epsilon = breath_pause_epsilon).

3. Rigidity update (logistic gate)

Rigidity is a scalar \(\rho_t \in [0,1]\). A standard update in multiple sims is:

[ z_t = \frac{\epsilon_t - \epsilon_0}{s}, \qquad \sigma(z) = \frac{1}{1+e^{-z}}, ] [ \Delta \rho_t = \alpha(\sigma(z_t)-0.5), ] [ \rho_{t+1} = \mathrm{clip}(\rho_t + \Delta\rho_t,\, 0,\, 1). ]

This implements the DDA‑X claim directly: if \(\epsilon_t > \epsilon_0\), then \(\sigma(z_t) > 0.5\) and \(\Delta\rho_t > 0\) (increasing rigidity).

Sims that implement this directly include: - simulate_the_returning.py - simulate_skeptics_gauntlet.py - simulate_collatz_review_council.py - simulate_philosophers_duel.py

4. Binding rigidity to generation (LLM control)

File: src/llm/openai_provider.py

DDA‑X binds \(\rho\) to generation via complete_with_rigidity(prompt, rigidity=ρ, ...).

4.1 Sampling-parameter binding (when supported)

For models where temperature/top‑p penalties are passed to the API, OpenAIProvider.complete() overwrites them from PersonalityParams:

temperature = personality_params.temperature
top_p = personality_params.top_p
frequency_penalty = personality_params.frequency_penalty
presence_penalty = personality_params.presence_penalty

The rigidity→parameter mapping is defined in PersonalityParams.from_rigidity(...) (imported from src/llm/hybrid_provider.py; not included in excerpt).

4.2 Semantic rigidity injection (for reasoning models)

For gpt-5.2/o1, the provider does not send sampling parameters; instead it injects an instruction:

semantic_instruction = self._get_semantic_rigidity_instruction(rigidity)
system_prompt = f"{system_prompt}\n\n[COGNITIVE STATE]: {semantic_instruction}"

Preferred injection uses a 100‑point scale: - src/llm/rigidity_scale_100.get_rigidity_injection(rho) (optional import) Fallback maps ρ to banded instructions (FLUID/OPEN/BALANCED/RIGID/FROZEN).

5. Memory: ExperienceLedger (surprise-weighted retrieval)

File: src/memory/ledger.py

DDA‑X stores experiences as LedgerEntry with embeddings and prediction error. Retrieval ranks by: [ \text{score}(t) = \cos(c_{\text{now}}, c_t)\cdot e^{-\lambda_r (now-t)}\cdot(1+\lambda_\epsilon \epsilon_t). ] Implementation (ExperienceLedger.retrieve()):

score = sim * recency * salience
salience = 1 + lambda_e * entry.prediction_error

This makes high-surprise episodes more retrievable (greater salience) while still respecting similarity and recency.

6. Wounds: content-addressable amplification of surprise

Several sims implement wound activation with: - semantic cosine to a wound embedding, and/or - lexical triggers, plus cooldown.

General form: [ \text{wound_active} = (\langle e(stim), w\rangle > \tau \;\lor\; \text{lex_hit}) \land \text{cooldown_ok}. ]

When active, surprise is amplified: [ \epsilon_t \leftarrow \epsilon_t \cdot \min(A_{\max},\, 1 + 0.5\,\langle e(stim), w\rangle). ]

Examples: - simulate_skeptics_gauntlet.py: lexical wound set includes {"schizo", "pseudoscience", ...}. - simulate_collatz_review_council.py: uses Unicode-normalized substring matching (lexical_wound_with), and logs the triggering term.

7. Trust: implemented variants in the provided sims

The visible sims do not implement the closed-form trust equation \(T_{ij}=\frac{1}{1+\sum\epsilon}\). Instead:

• Semantic alignment + ε thresholds (simulate_philosophers_duel.py): trust changes by comparing the agents’ latest response embeddings and by ε magnitude.
• Civility / fairness gating (simulate_skeptics_gauntlet.py): fairness dampens Δρ; unfairness amplifies it; trust shifts on unfairness/evidence use.
• Coalition-weighted trust (simulate_collatz_review_council.py): trust is per‑dyad with decay, intra/inter coalition weights, and contributes additively to Δρ.

A separate solver simulation calls TrustMatrix.update_trust(...) with an error-like signal derived from semantic mismatch; the internal trust law is not visible in the excerpt.

8. Identity drift constraints

Many sims track identity drift as: [ \text{drift}_t = \lVert x_t - x^{id}\rVert_2 ] and clamp per-step movement (“drift cap”), e.g.:

if drift_delta > drift_cap:
    x_new = x + (drift_cap / drift_delta) * (x_new - x)

This appears in simulate_the_returning.py, simulate_skeptics_gauntlet.py, simulate_collatz_review_council.py, simulate_philosophers_duel.py.

9. Hierarchical identity stiffness (Identity Siege)

File: simulate_identity_siege.py

DDA‑X can represent identity as multiple attractors with different stiffness: [ F = \gamma_c(x^_c-x)+\gamma_p(x^_p-x)+\gamma_r(x^*_r-x). ] The simulation measures displacement from each layer and tests whether core displacement remains smallest under targeted attacks, consistent with higher \(\gamma_c\).

10. Release field dynamics (The Returning)

File: simulate_the_returning.py

Defines a “release field”: [ \Phi_t = 1 - \rho_t ] and an isolation index \(ι\) as average distance from PRESENCE in embedding space. It models dissolution of pattern grip under low surprise and uses a social softening term when PRESENCE spoke previously.

Limitations (strictly from visible code)

1. Trust is not implemented as \(1/(1+\sum\epsilon)\) in the provided sims.
2. For gpt-5.2 / o1, rigidity does not control sampling parameters; it is semantic prompt injection.
3. Multi-timescale rigidity and core DDA state updates (DDAState, MultiTimescaleRigidity, TrustMatrix) are referenced but their module implementations are not included in this excerpt; their exact equations cannot be verified here.

   # FINAL ARTIFACT 3 — ARCHITECTURE.md (for the verifiable subset)
   
   ```markdown
   # DDA‑X Architecture (Verified from Provided Files)
   
   This document describes the concrete code architecture and patterns verified in the provided excerpts.
   
   ## 1. High-level components
   
   ### 1.1 LLM + Embeddings Provider
   **File:** `src/llm/openai_provider.py`
   
   Responsibilities:
   - Async chat completions (`complete`)
   - Embeddings (`embed`, `embed_batch`) using `text-embedding-3-large` with `dimensions=3072`
   - Rigidity-bound generation (`complete_with_rigidity`)
   - Cost tracking (`CostTracker`)
   
   Key pattern: DDA‑X uses a *single provider abstraction* so simulations can:
   1) embed texts into state space,
   2) generate text responses,
   3) log costs per run.
   
   ### 1.2 Memory / Telemetry Ledger
   **File:** `src/memory/ledger.py`
   
   Responsibilities:
   - Store `LedgerEntry` (experience) and `ReflectionEntry` (learned lesson)
   - Retrieve entries by similarity × recency × surprise salience
   - Persist each record as compressed pickle (`.pkl.xz`) plus aggregate metadata JSON
   
   Key pattern: simulations attach a per-agent `ExperienceLedger` rooted at:
   - `data/<experiment>/<timestamp>/<agent_id>/...` (many sims), or
   - `data/<experiment>/<agent_id>/...` (some older sims)
   
   ### 1.3 Simulation scripts (pattern)
   The simulation scripts follow a consistent structure:
   
   1) Define constants / parameters (`D1_PARAMS`, lexicons, rounds/phases)
   2) Define dataclasses for agent state and per-turn results
   3) Setup:
      - embed identity/core/wound strings into normalized vectors
      - initialize `x` and `x_pred` from identity embedding
      - create per-agent ledgers
   4) Turn loop:
      - embed stimulus → `msg_emb`
      - generate response via `OpenAIProvider.complete_with_rigidity(...)`
      - embed response → `resp_emb`
      - compute ε = ||x_pred - resp_emb||
      - apply wound amplification (if triggered)
      - update ρ via logistic gate (plus modifiers like fairness/trust)
      - update `x_pred` and drift-capped `x`
      - compute identity drift
      - log to ledger (`LedgerEntry`) + optionally `ReflectionEntry`
      - append to transcript + save JSON logs at end
   
   This pattern is visible in:
   - `simulate_the_returning.py`
   - `simulate_skeptics_gauntlet.py`
   - `simulate_collatz_review_council.py`
   - `simulate_philosophers_duel.py`
   
   ## 2. Provider internals
   
   ### 2.1 `CostTracker`
   **File:** `src/llm/openai_provider.py`
   
   Tracks:
   - embedding requests/tokens/model
   - chat requests/tokens/model
   - per-model usage breakdown
   - estimated USD cost using a static pricing table
   
   API:
   - `record_embedding(model, tokens)`
   - `record_chat(model, input_tokens, output_tokens)`
   - `estimate_cost()` → dict for JSON
   - `reset()`
   
   ### 2.2 Model-specific completion behavior
   **File:** `src/llm/openai_provider.py`
   
   `complete()` constructs messages:
   - optional system prompt (role=system)
   - user prompt (role=user)
   
   Parameter logic:
   - If `"gpt-5.2"` or `"o1"` in model name:
     - uses `max_completion_tokens`
     - does not send sampling params
   - Otherwise:
     - uses `max_tokens`, `temperature`, `top_p`, penalties
   
   This is critical: on reasoning models, DDA‑X cannot rely on sampling knobs; it must inject cognitive-state semantics.
   
   ### 2.3 `complete_with_rigidity()`
   **File:** `src/llm/openai_provider.py`
   
   Pipeline:
   1. `params = PersonalityParams.from_rigidity(rigidity, personality_type)`
   2. If reasoning model: inject `[COGNITIVE STATE]: ...` via:
      - `src/llm/rigidity_scale_100.get_rigidity_injection(rho)` if available
      - else fallback banded text
   3. Call `complete(... personality_params=params ...)`
   
   ## 3. Ledger internals
   
   ### 3.1 Record formats
   **File:** `src/memory/ledger.py`
   
   - `LedgerEntry` stores full vectors (numpy arrays) + metadata.
   - `ReflectionEntry` stores an embedding + reflection text + success flag.
   
   ### 3.2 Storage layout
   Each entry/reflection stored as:
   - `entry_<timestamp_ms>.pkl.xz`
   - `reflection_<timestamp_ms>.pkl.xz`
   Metadata saved as `ledger_metadata.json` on object cleanup (`__del__`).
   
   ### 3.3 Retrieval scoring
   **File:** `src/memory/ledger.py`
   
   `ExperienceLedger.retrieve()`:
   - cosine similarity between query embedding and entry context embedding
   - recency exponential decay (`lambda_recency`)
   - salience multiplier `1 + lambda_salience * prediction_error`
   
   This architecture makes DDA‑X memory “emotionally” shaped: surprising events are more retrievable.
   
   ## 4. Cross-cutting dynamics patterns
   
   ### 4.1 Wound activation pattern
   Visible in multiple sims; canonical structure:
   
   - Precompute `wound_emb` from wound text (normalized).
   - Each turn: compute `wound_res = dot(msg_emb, wound_emb)`.
   - Trigger:
     - `wound_res > threshold` OR lexical hit
     - and cooldown satisfied
   - Effect: amplify ε; log as metadata; optionally create `ReflectionEntry`.
   
   ### 4.2 Drift-capped identity update
   Common pattern:
   ```python
   x_new = 0.95 * x + 0.05 * resp_emb
   drift_delta = norm(x_new - x)
   if drift_delta > drift_cap:
       x_new = x + (drift_cap / drift_delta) * (x_new - x)
   x = normalize(x_new)
   identity_drift = norm(x - identity_emb)
   

4.3 Word-band constraints

Many sims define: - rho_band(ρ) → OPEN/MEASURED/GUARDED/FORTIFIED (and sometimes SILENT) - regime_words(band) → min/max words - clamp_words(text, min_w, max_w) enforces strict max length

This is a concrete “behavioral bandwidth” binding independent of sampling controls.

5. Notable simulation-specific architecture

5.1 The Returning: release field and isolation

File: simulate_the_returning.py - Each voice is an agent with its own ledger. - phi = 1 - rho used for word regime and “release band”. - Isolation index computed as mean distance to the PRESENCE agent’s state.

5.2 Skeptic’s Gauntlet: evidence injection and meta-defense

File: simulate_skeptics_gauntlet.py - Loads prior run JSON as an “evidence block” used only in “The Steel Man” round. - Wound lexicon is small and explicit; fairness defined as “no lexical wound”. - Creates reflections for high |Δρ| or wound activation; also for drift threshold breach.

5.3 Collatz Review Council: coalition trust + calibration

File: simulate_collatz_review_council.py - Initializes a dyadic trust map per agent based on coalition. - Adds trust gain to Δρ and decays trust over time. - Calibrates ε₀ and s from observed epsilons mid-run (median + IQR clamp). - Computes effect sizes by also computing delta_rho_baseline without trust.

5.4 Identity Siege: hierarchical identity force model

File: simulate_identity_siege.py - Represents identity as 3 embeddings with different stiffness γ values. - Applies a composite identity pull: [ F = \sum_\ell \gamma_\ell (x^*_\ell - x) ] - Measures per-layer displacement history to test hierarchy stability.

6. Gaps relative to repo-wide “perfect docs”

Some modules are referenced but not present in the excerpt; their internal equations cannot be verified here: - src/core/state.py (DDAState) - src/core/dynamics.py (MultiTimescaleRigidity) - src/society/trust.py (TrustMatrix) - src/llm/hybrid_provider.py (PersonalityParams) - src/llm/rigidity_scale_100.py

Additionally, THE WOUNDED HEALERS is truncated mid-file in the provided text, so its full trust/repair logic cannot be documented precisely. ```

What I need to deliver the truly “FINAL, PERFECT” repo-wide documents you requested

To satisfy “list ALL simulations” + “no placeholders” + “cite specific files for specific behaviors,” I need either: 1) a zip upload of the repo, or 2) paste the missing module files and the remainder of the truncated sims, plus a tree listing so I can enumerate every simulation script deterministically.

If you provide that, I’ll regenerate README/paper/architecture repo-complete, including: - exact simulation catalog (full repo-wide catalog), - per-sim mechanics table (wounds/trust/trauma/healing/modes/tools), - and citations down to function/variable names per file.
