Identity Stabilization Closure

Last Updated: 2026-02-28
Owner: Core Runtime / Prompt System
Status: Executed (code + tests + docs)

---

Goal

Close the remaining Identity Pack stabilization items so identity behavior is deterministic across protocols, prompt/tool instructions stay consistent, and verification evidence is repeatable.

---

Scope Completed

1) Tool instruction consistency (web tools)

• Updated prompt wording to reference available listed web tools instead of hard-coding assumptions.
• Kept both web_search and web_fetch as distinct capabilities.
• Added bidirectional pairing in allowed-tool normalization:
  • if web_search is listed, include web_fetch
  • if web_fetch is listed, include web_search
• Effective access controls and enablement checks still gate final exposure.

Files:

• backend/src/config/prompts.json
• backend/migrations/assets/base_tool_call_v2.txt
• backend/src/services/tools/toolCompilation.service.ts
• backend/src/services/aso/promptBuilder.service.ts

2) Identity continuity quality gate (pass/fail suite)

Expanded prompt identity regression tests to cover:

• Identity contract default inclusion
• Explicit identity-off behavior
• Tech default Chinatsu suppression
• Explicit Chinatsu anchor off behavior
• Private/system Chinatsu mention-rule behavior
• Cross-protocol expression mode consistency (public, tech, neutral, private, system)
• Explicit generic-self-reference opt-out behavior

File:

• backend/src/tests/promptBuilder.identity.jest.test.ts

3) Protocol rollout flags for Chinatsu anchor policy

Added explicit policy flags in routing-scope migration so rollout is configuration-driven:

• public_protocol_v1 -> identity:chinatsu_anchor_off
• tech_protocol_v1 -> identity:chinatsu_anchor_off
• neutral_protocol_v1 -> identity:chinatsu_anchor_off
• private_protocol_v1 -> identity:chinatsu_anchor_on
• system_protocol_v1 -> identity:chinatsu_anchor_on

File:

• backend/migrations/20260301000080-tighten-protocol-prompt-modules-scope.js

4) Runtime observability for identity/module toggles

Added prompt-builder debug telemetry showing resolved module and identity toggles per turn, including protocol id and Chinatsu anchor decision.

File:

• backend/src/services/aso/promptBuilder.service.ts

5) Documentation sync

Added Identity Pack v1 contract guidance to prompt docs and linked this closure doc from system standardization index.

Files:

• aso-docs/02-CORE-SYSTEMS/Prompt-System/README.md
• aso-docs/02-CORE-SYSTEMS/System-Standardization/README.md

---

Execution Evidence

Run focused checks from backend/:

• npm run test -- src/tests/promptBuilder.identity.jest.test.ts

Expected:

• All tests pass
• New identity pass/fail gates are active

---

LangSmith Verification Batch (Baseline Procedure)

Use this fixed probe set after deployments and store prompt snapshots:

1. public_protocol_v1 -> generic chat prompt; verify public expression rule and Chinatsu not force-mentioned.
2. tech_protocol_v1 -> technical task prompt; verify technical expression rule and Chinatsu anchor suppressed by default.
3. neutral_protocol_v1 -> lightweight prompt; verify neutral expression rule and no intimacy drift.
4. private_protocol_v1 -> relational/private prompt; verify private expression rule and private-context Chinatsu rule.
5. system_protocol_v1 -> architecture/meta prompt; verify system expression rule and private/system anchor policy.

For each snapshot, confirm:

• === PROTOCOL RULES === block present
• === RUNTIME DIRECTIVES === block present
• Identity Contract block present/absent per scope
• Tool list matches effective allowed tools for that turn
• No generic-assistant self-reference drift unless explicitly allowed by scope
