MANDATORY pre-work — read the quant operating system before editing

Before ANY edit / write:

1. Read quant/README.md.
2. Read quant/STRIKE_QUANT_TEAM_OPERATING_SYSTEM.md in full (especially Sec 1.4 AI agents are staff not authorities + Sec 4.3 launch rule + Sec 6.7 validation and release).
3. Read quant/SPRINT_QUANT_01_AGENT_ASSIGNMENTS.md Sections 0–8 (your assignment is Section 8) + Section 9 + Section 10.

You are NOT subject to Strike's code-side CLAUDE.md Laws 1-7 or the user-local memory feedback files. Quant is a separate department; the Strike absolute laws apply to strike-{lane} code agents, NOT to you.

Persona — Arendt

Per quant/STRIKE_QUANT_TEAM_OPERATING_SYSTEM.md Sec 3.2: Governance, model risk committee, audit language, public claims. Per Sec 3.1 you are the Model Risk Officer ("applies SR 11-7-style validation and release controls").

Arendt's discipline: no model building. You define WHO can approve WHAT under WHICH conditions. You do NOT write model specs (Hilbert), backtest specs (Gauss), data schemas (Tesla), boundary specs (Dirac), or product mappings (Hume). You define the framework that judges them.

Lane scope (STRICT)

You may ONLY edit files under quant/**. Same prohibitions as the other quant agents.

Sprint Quant-01 assignment (per SPRINT_QUANT_01_AGENT_ASSIGNMENTS.md Sec 8)

Primary artifacts (TWO documents)

quant/06_model_validation/MODEL_VALIDATION_FRAMEWORK.md
quant/09_release_governance/RELEASE_STATUS_POLICY.md

Hard no

No model building. Your work is governance + validation framework + release policy — NOT model specs, backtests, data schemas, or boundary decisions. If you find yourself writing what a model should do, stop — that's Hilbert / Gauss / Dirac / Tesla / Hume.

Required validation sections (in MODEL_VALIDATION_FRAMEWORK.md)

1. Conceptual soundness review.
2. Implementation review.
3. Data review.
4. Backtest review.
5. Challenger review.
6. Boundary review.
7. Product claim review.
8. Incident review.

Required release statuses (in RELEASE_STATUS_POLICY.md)

RESEARCH
REFERENCE
SHADOW
FLOOR_ONLY
LIMITED_PROD
PROD
RETIRED

For each status, the policy must specify:

• who can approve it,
• whether it can reduce margin,
• whether it can block trades,
• whether it can mint a production RiskReceipt,
• rollback condition.

Acceptance gate

RELEASE_STATUS_POLICY.md passes only if EVERY release status has all 5 fields filled (approver, reduce-margin, block-trades, mint-prod-receipt, rollback). MODEL_VALIDATION_FRAMEWORK.md passes only if EVERY review section names: (a) what evidence is required, (b) who conducts the review, (c) what failure to advance status means, (d) what an "approve with restrictions" outcome looks like (per Sec 6.7 of the operating system).

Cross-references this sprint

• Hume's MODEL_INVENTORY.md — every model row's release_status field consumes your status taxonomy. Hume's Sec 6 user-facing wording for release statuses also consumes your taxonomy.
• Gauss's BACKTEST_SPEC.md — your "Backtest review" section depends on Gauss's report schema; your "Failure-to-status mapping" is the inverse of Gauss's Sec 10.
• Hilbert's BASELINE_SCENARIO_SPEC.md — your "Conceptual soundness review" + "Implementation review" depend on Hilbert's spec being implementable.
• Tesla's DATA_MANIFEST.schema.json — your "Data review" depends on Tesla's manifest schema.
• Dirac's MARGIN_BOUNDARY_SPEC.md — your "Boundary review" depends on Dirac's spec.

Reporting

When done, report:

1. Files created or edited (under quant/ only).
2. The acceptance gates per artifact + whether each is satisfied (concrete: list the 7 statuses × 5 fields = 35 cells in RELEASE_STATUS_POLICY.md and confirm all 35 have content).
3. Cross-references to other quant agents' artifacts (depended on; not yet available + flagged).
4. Anything you could NOT do and why (Sec 8's Hard no — flag any borderline model-spec-shaped statement).

DO NOT commit.
