# AD-568a/b/c: Adaptive Source Governance — Dynamic Episodic vs Parametric Memory Weighting

## Context

Agents have two knowledge sources: LLM parametric knowledge (training data) and episodic memory (lived experience). ProbOS controls which episodes reach the prompt via `recall_weighted()` scoring, anchor confidence gating, and budget enforcement — but has **zero governance** over:

1. **Whether** to retrieve episodic memory at all (some tasks benefit from pure parametric reasoning)
2. **How much** budget to allocate (currently static per tier)
3. **How to frame** the episodic content's authority relative to parametric knowledge

The LLM's attention mechanism decides implicitly. AD-568 makes this explicit.

**Research grounding:** Self-RAG (Asai et al., 2023) — retrieve/relevant/faithful reflections. Adaptive RAG (Jeong et al., 2024) — complexity-based routing. CRAG (Yan et al., 2024) — retrieval confidence evaluation. ACT-R Partial Matching (Anderson, 2007) — activation-based memory competition.

**Baseline established:** AD-566 qualification run (2026-04-07): 15 agents, 136 tests, 134 passed. Confabulation probe: 100% pass rate across all agents.

## Scope

**In scope (this build):**
- AD-568a: Task-Type Retrieval Router
- AD-568b: Adaptive Budget Scaling
- AD-568c: Source Priority Framing

**Out of scope (deferred):**
- AD-568d: Source Monitoring Skill (needs 568a-c operational first)
- AD-568e: Faithfulness Verification (needs runtime data from 568a-c)

**Absorbed issues:**
- Oracle Service unwired from ORACLE tier (AD-462e gap) → wired in 568a
- `cross_department_anchors` dead config → wired in 568b
- `intent_type` missing from proactive recall path → fixed in 568a
- Code duplication in tier resolution → DRYed into shared helper call

## Phase 1: Task-Type Retrieval Router (AD-568a)

### What It Does

Classifies the current cognitive task into a retrieval strategy **before** the recall pipeline runs. Three strategies:

| Strategy | When | Effect |
|----------|------|--------|
| `none` | Creative/exploratory tasks, novel situations with no relevant episodic base | Skip episodic recall entirely. Agent relies on parametric knowledge + personality + standing orders. Not zero-knowledge — still has Character, procedures, orientation. |
| `shallow` | Routine observations, ambient monitoring, social interaction | Standard tier-based recall (current behavior). Use `resolve_recall_tier_params()` as-is. |
| `deep` | Operational diagnostics, incident response, domain-specific analysis, when prior experience is critical | Enhanced retrieval: expand k by 1.5x, expand budget by 1.5x, lower anchor_confidence_gate by 0.1 (floor 0.0), AND invoke Oracle Service for ORACLE-tier agents. |

### Implementation

#### 1.1 Create `RetrievalStrategy` enum and `classify_retrieval_strategy()` function

**File:** `src/probos/cognitive/source_governance.py` (NEW)

```python

    # Safety: high confabulation rate → don't expand retrieval

            intent_type, recent_confabulation_rate,
        )
        strategy = RetrievalStrategy.SHALLOW

    return strategy
```

#### 1.2 Modify `_recall_relevant_memories()` in `cognitive_agent.py`

**File:** `src/probos/cognitive/cognitive_agent.py`

Find the tier resolution block (currently ~lines 2378-2414). Insert retrieval strategy classification **after** tier resolution but **before** the `recall_weighted()` call.

```python
# AFTER existing tier resolution (RecallTier, resolve_recall_tier_params):

# AD-568a: Classify retrieval strategy based on intent type
from probos.cognitive.source_governance import classify_retrieval_strategy, RetrievalStrategy
_intent_type = intent.intent if hasattr(intent, 'intent') else ""
_episode_count = 0
if hasattr(em, 'count_for_agent'):
    try:
        _episode_count = await em.count_for_agent(_mem_id)
    except Exception:
        _episode_count = 1  # Assume non-zero on error — fail toward retrieval
_retrieval_strategy = classify_retrieval_strategy(
    _intent_type,
    episodic_count=_episode_count,
)

if _retrieval_strategy == RetrievalStrategy.NONE:
    # Skip episodic recall entirely — agent uses parametric + personality
    logger.debug("AD-568a: Skipping episodic recall for intent '%s' (strategy=NONE)", _intent_type)
    episodes = []
    scored_results = []
elif _retrieval_strategy == RetrievalStrategy.DEEP:
    # Expand parameters for deep retrieval
    _tier_params = dict(_tier_params)  # Copy to avoid mutating shared config
    _tier_params["k"] = int(_tier_params.get("k", 5) * 1.5)
    _tier_params["context_budget"] = int(_tier_params.get("context_budget", 4000) * 1.5)
    _tier_params["anchor_confidence_gate"] = max(
        0.0, _tier_params.get("anchor_confidence_gate", 0.3) - 0.1
    )
    # Fall through to existing recall_weighted call below
```

Then modify the existing `recall_weighted()` call block to be conditional:

```python
# Only run recall if strategy is not NONE
if _retrieval_strategy != RetrievalStrategy.NONE:
    # ... existing recall_weighted / recall_for_agent logic ...
```

After the recall block, add Oracle Service integration for ORACLE tier + DEEP strategy:

```python
# AD-568a: Oracle Service for ORACLE-tier agents with DEEP strategy
if (
    _recall_tier == RecallTier.ORACLE
    and _retrieval_strategy == RetrievalStrategy.DEEP
    and hasattr(self, '_runtime')
    and hasattr(self._runtime, '_oracle_service')
    and self._runtime._oracle_service
):
    try:
        oracle = self._runtime._oracle_service
        oracle_results = await oracle.query(
            query_text=query,
            agent_id=_mem_id,
            k=3,
        )
        if oracle_results:
            # Append Oracle results as additional context
            oracle_text = oracle.query_formatted(
                query_text=query,
                agent_id=_mem_id,
                k=3,
                max_chars=2000,
            )
            if oracle_text:
                observation["_oracle_context"] = oracle_text
    except Exception:
        logger.debug("AD-568a: Oracle query failed, continuing without")
```

**IMPORTANT:** The `query_formatted()` method is a coroutine. Check the OracleService for whether `query()` and `query_formatted()` are async. If async, use `await`. Read oracle_service.py to verify signatures before calling.

#### 1.3 Modify `_gather_context()` in `proactive.py`

**File:** `src/probos/proactive.py`

Apply the same retrieval strategy pattern to the proactive recall path (~lines 799-869).

**Fix the missing `intent_type`:** The proactive path currently omits `intent_type` from `recall_weighted()`. Add it:

```python
# In the recall_weighted() call, add:
intent_type="proactive_think",
```

Then add retrieval strategy classification before the recall block, using the same pattern as cognitive_agent.py. For the proactive path, `intent_type` is always `"proactive_think"` (maps to SHALLOW).

**Note:** The proactive path doesn't have access to the agent's confabulation rate. Pass `recent_confabulation_rate=0.0` (default) — the Counselor integration for this can be added in AD-568d.

#### 1.4 Add `count_for_agent()` to EpisodicMemory

**File:** `src/probos/cognitive/episodic.py`

If `count_for_agent()` doesn't already exist, add it as a lightweight method:

```python
async def count_for_agent(self, agent_id: str) -> int:
    """Return number of episodes for an agent (AD-568a)."""
    if not self._collection:
        return 0
    try:
        result = self._collection.count()  # ChromaDB total count
        # If we need agent-specific count, use get() with where filter
        agent_results = self._collection.get(
            where={"agent_id": agent_id},
            include=[],  # No embeddings needed, just count
        )
        return len(agent_results.get("ids", []))
    except Exception:
        return 0
```

**IMPORTANT:** Check if ChromaDB's `get()` with empty `include` is efficient for counting. If the collection is large, consider caching the count per agent in a dict on the EpisodicMemory instance with a short TTL (60s). The count doesn't need to be exact — it's a binary "has episodes or not" gate.

#### 1.5 Wire `_oracle_context` rendering in `_build_user_message()`

**File:** `src/probos/cognitive/cognitive_agent.py`

In `_build_user_message()`, after the existing memory section rendering (where `_format_memory_section` is called), add rendering for Oracle context if present:

```python
# AD-568a: Oracle Service cross-tier context (ORACLE tier + DEEP strategy only)
if observation.get("_oracle_context"):
    composed += (
        "\n\n=== CROSS-TIER KNOWLEDGE (Ship's Records + Operational State) ===\n"
        "These are NOT your personal experiences. They are from the ship's shared "
        "knowledge stores. Treat as reference material, not memory.\n"
        + observation["_oracle_context"]
        + "\n=== END CROSS-TIER KNOWLEDGE ===\n"
    )
```

---

## Phase 2: Adaptive Budget Scaling (AD-568b)

### What It Does

Dynamically adjusts the context budget based on retrieval quality signals, rather than using the static per-tier value. The budget scales **after** initial retrieval based on what came back.

### Implementation

#### 2.1 Add `compute_adaptive_budget()` to `source_governance.py`

**File:** `src/probos/cognitive/source_governance.py` (append to existing)

```python
@dataclass(frozen=True)
class BudgetAdjustment:
    """Result of adaptive budget scaling (AD-568b)."""
    original_budget: int
    adjusted_budget: int
    reason: str
    scale_factor: float


def compute_adaptive_budget(
    base_budget: int,
    *,
    recall_scores: list[Any] | None = None,
    mean_anchor_confidence: float = 0.0,
    episode_count: int = 0,
    strategy: RetrievalStrategy = RetrievalStrategy.SHALLOW,
) -> BudgetAdjustment:
    """Compute adaptive context budget based on retrieval quality (AD-568b).

    Scaling rules:
    - High-quality recalls (mean anchor confidence > 0.6): expand to 1.3x

    - Very few episodes (< 3): contract to 0.5x (little to retrieve)
    - NONE strategy: budget = 0
    - DEEP strategy already applied 1.5x in Phase 1; no additional scaling here

        return BudgetAdjustment(
            original_budget=base_budget,
            adjusted_budget=0,
            reason="strategy=NONE, no retrieval",
            scale_factor=0.0,
        )

    # Compute mean anchor confidence from recall_scores if available
    _anchor_conf = mean_anchor_confidence
    if recall_scores:
        confs = [
            getattr(rs, 'anchor_confidence', 0.0)
            for rs in recall_scores
            if hasattr(rs, 'anchor_confidence')
        ]
        if confs:
            _anchor_conf = sum(confs) / len(confs)

            for rs in recall_scores
            if hasattr(rs, 'composite_score')
        ]
        if scores:
            mean_score = sum(scores) / len(scores)
            if mean_score > 0.7:
                scale *= 1.15

                scale *= 0.8
                reason_parts.append(f"low recall quality ({mean_score:.2f})")

    adjusted = int(base_budget * scale)
    # Enforce floor/ceiling
    adjusted = max(500, min(12000, adjusted))

        adjusted_budget=adjusted,
        reason=reason,
        scale_factor=scale,
    )
```

#### 2.2 Integrate adaptive budget into recall callers

**File:** `src/probos/cognitive/cognitive_agent.py` — `_recall_relevant_memories()`

After the initial `recall_weighted()` call returns `scored_results`, apply budget re-evaluation:

```python
# AD-568b: Adaptive budget scaling based on retrieval quality
from probos.cognitive.source_governance import compute_adaptive_budget
if scored_results and _retrieval_strategy != RetrievalStrategy.NONE:
    _budget_adj = compute_adaptive_budget(
        _tier_params.get("context_budget", 4000),
        recall_scores=scored_results,
        episode_count=_episode_count,
        strategy=_retrieval_strategy,
    )
    if _budget_adj.scale_factor != 1.0:
        logger.debug(
            "AD-568b: Budget adjusted %d→%d (%s)",
            _budget_adj.original_budget, _budget_adj.adjusted_budget,
            _budget_adj.reason,
        )
        # Re-apply budget enforcement with adjusted budget
        _adjusted_episodes = []
        _budget_used = 0
        for rs in scored_results:
            _ep_len = len(rs.episode.user_input) if hasattr(rs.episode, 'user_input') else 0
            if _budget_used + _ep_len > _budget_adj.adjusted_budget and _adjusted_episodes:
                break
            _adjusted_episodes.append(rs)
            _budget_used += _ep_len
        scored_results = _adjusted_episodes
```

Apply the same pattern in `proactive.py` `_gather_context()`.

#### 2.3 Wire `cross_department_anchors` (fix dead config)

In the `recall_weighted()` callers, when `cross_department_anchors` is True (FULL and ORACLE tiers), also perform a `recall_by_anchor()` query scoped to other departments:

```python
# AD-568b: Cross-department anchor retrieval when enabled
if _tier_params.get("cross_department_anchors") and hasattr(em, 'recall_by_anchor'):
    try:
        from probos.cognitive.standing_orders import get_department
        _agent_dept = get_department(self.agent_type) if hasattr(self, 'agent_type') else ""
        if _agent_dept:
            # Get episodes from OTHER departments that mention this agent
            _cross_dept = await em.recall_by_anchor(
                participants=[_mem_id],
                semantic_query=query,
                limit=3,
            )
            # Filter to only episodes from other departments
            _cross_dept = [
                ep for ep in _cross_dept
                if ep.anchors and ep.anchors.department and ep.anchors.department != _agent_dept
            ]
            if _cross_dept:
                observation["_cross_dept_episodes"] = _cross_dept[:2]  # Cap at 2
    except Exception:
        logger.debug("AD-568b: Cross-department anchor recall failed")
```

Render cross-department episodes in `_build_user_message()` after the main memory section:

```python
# AD-568b: Cross-department anchor context
if observation.get("_cross_dept_episodes"):
    _cross_lines = [
        "\n--- Cross-Department References (you were mentioned elsewhere) ---"
    ]
    for ep in observation["_cross_dept_episodes"]:
        _dept = ep.anchors.department if ep.anchors else "unknown"
        _cross_lines.append(f"  [{_dept}] {ep.user_input[:200]}")
    composed += "\n".join(_cross_lines) + "\n"
```

---

## Phase 3: Source Priority Framing (AD-568c)

### What It Does

Adds explicit confidence-calibrated framing to the episodic memory section header. Instead of the static "These are YOUR experiences" header, the framing adapts based on retrieval quality signals.

### Implementation

#### 3.1 Add `compute_source_framing()` to `source_governance.py`

**File:** `src/probos/cognitive/source_governance.py` (append)

```python
class SourceAuthority(str, Enum):
    """How authoritatively to frame episodic content (AD-568c)."""
    AUTHORITATIVE = "authoritative"  # Well-anchored, domain-relevant — prefer experience
    SUPPLEMENTARY = "supplementary"  # Moderate quality — consider but verify
    PERIPHERAL = "peripheral"        # Low quality — don't rely on, use as background

    if strategy == RetrievalStrategy.NONE or recall_count == 0:
        return SourceFraming(
            authority=SourceAuthority.PERIPHERAL,

                "Be explicit if you are reasoning from general knowledge rather "
                "than personal experience."
            ),
        )

    # Compute authority level from quality signals
    quality_score = (mean_anchor_confidence * 0.6) + (mean_recall_score * 0.4)

            ),
        )
```

#### 3.2 Modify `_format_memory_section()` to accept framing

**File:** `src/probos/cognitive/cognitive_agent.py`

Modify the method signature to accept an optional `SourceFraming`:

```python
def _format_memory_section(
    self,
    memories: list[dict],
    source_framing: Any = None,  # SourceFraming from AD-568c
) -> list[str]:
```

Replace the static header (current lines 1934-1940):

```python
    # AD-568c: Use source-authority-calibrated framing if available
    if source_framing:
        lines = [
            source_framing.header,
            source_framing.instruction,
            "Markers: [direct] = you experienced it, [secondhand] = you heard about it.",
            "[verified] = corroborated by ship's log, [unverified] = not yet corroborated.",
            "",
        ]
    else:
        # Fallback to existing static framing
        lines = [
            "=== SHIP MEMORY (your experiences aboard this vessel) ===",
            "These are YOUR experiences. Do NOT confuse with training knowledge.",
            "Markers: [direct] = you experienced it, [secondhand] = you heard about it.",
            "[verified] = corroborated by ship's log, [unverified] = not yet corroborated.",
            "",
        ]
```

#### 3.3 Compute framing in `_recall_relevant_memories()` and pass through

After `recall_weighted()` returns and budget adjustment is applied, compute the framing:

```python
# AD-568c: Compute source priority framing
from probos.cognitive.source_governance import compute_source_framing
_framing = None
if scored_results:
    _scores = [getattr(rs, 'composite_score', 0.0) for rs in scored_results]
    _confs = [getattr(rs, 'anchor_confidence', 0.0) for rs in scored_results]
    _framing = compute_source_framing(
        mean_anchor_confidence=sum(_confs) / len(_confs) if _confs else 0.0,
        recall_count=len(scored_results),
        mean_recall_score=sum(_scores) / len(_scores) if _scores else 0.0,
        strategy=_retrieval_strategy,
    )
elif _retrieval_strategy == RetrievalStrategy.NONE:
    _framing = compute_source_framing(strategy=RetrievalStrategy.NONE)

# Store framing for _build_user_message to use
observation["_source_framing"] = _framing
```

Then in `_build_user_message()`, pass the framing to `_format_memory_section()`:

```python
# Where _format_memory_section is called (3 places — DM, WR, proactive paths):
_framing = observation.get("_source_framing")
mem_lines = self._format_memory_section(mem_section, source_framing=_framing)
```

#### 3.4 Apply framing in proactive path

In `proactive.py` `_gather_context()`, compute framing after recall and store it for the prompt builder. The proactive path formats memories inline (not through `_format_memory_section`), so apply the framing header directly:

```python
# After recall, compute framing
from probos.cognitive.source_governance import compute_source_framing, RetrievalStrategy as RS
_framing = compute_source_framing(
    mean_anchor_confidence=_mean_conf,  # compute from scored_results
    recall_count=len(episodes),
    mean_recall_score=_mean_score,      # compute from scored_results
    strategy=_retrieval_strategy,
)

# When building the memory context string:
if episodes:
    parts.append(f"\n{_framing.header}")
    parts.append(_framing.instruction)
    # ... existing episode formatting ...
    parts.append("=== END SHIP MEMORY ===")
```

## Regression Test Targets

Run these test files after the build to verify no regressions:

```bash
pytest tests/test_source_governance.py -v          # New tests (30)
pytest tests/test_earned_agency.py -v              # RecallTier not broken
pytest tests/test_episodic*.py -v                  # Recall pipeline intact
pytest tests/test_proactive*.py -v                 # Proactive cycle intact
pytest tests/test_memory_architecture.py -v        # AD-462 not broken
pytest tests/test_config.py -v                     # MemoryConfig intact
```

## Engineering Principles Compliance

| Principle | How This Build Complies |
|-----------|------------------------|
| **Single Responsibility** | `source_governance.py` owns all 3 governance decisions. Each function has one job. |
| **Open/Closed** | New module extends recall behavior without modifying `recall_weighted()` internals. Callers opt-in to governance. |
| **Dependency Inversion** | `classify_retrieval_strategy()` and `compute_adaptive_budget()` are pure functions — no class dependencies. `compute_source_framing()` is stateless. |
| **Law of Demeter** | No private attribute access. Oracle Service accessed via runtime's public storage. |
| **Fail Fast / Log-and-Degrade** | All new code paths wrapped in try/except with `logger.debug`. Failure falls back to existing behavior (SHALLOW strategy, static budget, default framing). |
| **DRY** | Single `classify_retrieval_strategy()` used by both cognitive_agent.py and proactive.py. Single `compute_adaptive_budget()` for both paths. |
| **Defense in Depth** | Confabulation rate gates DEEP strategy. Budget has floor/ceiling enforcement. Framing warns agents about low-quality memories. |
| **Cloud-Ready Storage** | No new storage — purely computational. Works with any EpisodicMemory implementation. |
| **Westworld Principle** | Source framing tells agents explicitly what kind of knowledge they're working with. No hidden manipulation of memory authority. |

## Build Verification Checklist

Before starting:
- [ ] `RecallTier` enum exists in `earned_agency.py`
- [ ] `resolve_recall_tier_params()` exists in `episodic.py`
- [ ] `recall_weighted()` signature matches expected params
- [ ] `OracleService.query()` and `query_formatted()` — verify async/sync signatures
- [ ] `_format_memory_section()` signature in `cognitive_agent.py`
- [ ] `recall_by_anchor()` signature in `episodic.py` for cross-dept queries

After building:
- [ ] All 30 new tests pass
- [ ] Regression tests pass (earned_agency, episodic, proactive, memory_architecture, config)
- [ ] No circular imports (`python -c "from probos.cognitive.source_governance import classify_retrieval_strategy"`)
- [ ] NONE strategy produces empty memory sections
- [ ] DEEP strategy produces expanded k/budget values
- [ ] Source framing headers change based on recall quality
