Hook-Enforced Compliance

Wiki route

This entry sits under systems index. Read it against Threshold BFT consensus Rust implementation trend for peer / contrast context and fintech index for the broader system / regulatory boundary.

5 -Layer Defense Model (personal OS)

Layer	Nature	Implementation
1	Pre-injection (hardest)	UserPromptSubmit hook → injects a HARD RULE reminder before response generation
2	Output-format enforcement	Pre-flight Compliance Check → `🌅 Trigger: ...` in the first ROUTER line
3	Subagent self-attestation	Subagent declares “Task() true launch” on the first line
4	Post-run audit	AUDITOR Compliance Patrol (Mode 3) 7-class taxonomy

Essence by layer:

Layer 1 is injection (before the main contract)
Layer 2-3 is format enforcement (response structure)
Layer 4 is tracking (accumulating past violations and escalating)
Layer 5 is prevention (preventing modifications from reviving past bugs)

First verification pattern

deployment ≠ working. Even if a Hook is placed, whether it actually fires is a separate issue.

Flow until the first actual operation:

Deploy (placement) → static state
First trigger → observe whether it fires
Firing success → reminder injection arrives
Observable effect → the LLM’s response changes

This wiki entry itself records that moment: during the 2026-04-21 session close, the Layer 1 hook fired successfully for the first time.

Escalation Staircase (higher enforcement strength according to violation frequency)

This design is not a single defense; enforcement strength rises according to frequency:

≥3 same type / 30 days → hook strictness UP (the reminder names the specific issue)
≥5 same type / 30 days → pre-place 🚨 Compliance Watch: [type] in the Start Session briefing
≥10 same type / 90 days → run AUDITOR Patrol every Session

Applicability

Contracts and SOPs: “written = followed” is not true · audits, penalties, and logs are the enforcement mechanism
Code conventions: lint / CI / pre-commit hooks are equivalent to Layer 1
Organizational processes: review steps / sign-off are equivalent to Layer 4
Regulatory compliance: inspections by supervisory authorities are equivalent to Layer 4 · self-inspections are equivalent to Layer 3 (financial-domain examples run alongside FSA Business Improvement Order (BIO) domestic VASP administrative-action history (2018-2026) and JVCEA: Overview of the Self-Regulatory Framework)

Relationship with cognitive traits

Sensitivity to this pattern is linked to SOUL strong rule awareness and pursuit of system integrity (observing candidate · 2026-04-21 newly created). The appearance of this wiki entry itself is evidence of that trait.
