Kjell Tore Guttormsen 9a4caeb419 feat(loop): S8 — D7 agentic loop: budget meter, maker-checker gate, informed refinement 
Spec §3 steps 2–5 + §8, TDD-ed offline (scripted, honesty-marked stand-in):
- budget.py: BudgetMeter over TerminationContract — provider-reported usage
  only (missing usage fails closed), structured BudgetExceeded stop event.
- loop.py: ModelClient protocol; blind parse-retry generation (never silent
  repair); round-capped debate with turn safety net and mandated VERDICT
  line; opt-in-reject checker gate (explicit REJECT overrides a validated
  outcome, validator rejection stands); most-recent-reason-verbatim informed
  refinement under max_attempts; validator_decision stamped BEFORE override,
  checker_decision as its own result field (§9, never conflated).
- 45 new tests (121 total, no API key); four detach proofs run RED and
  reverted green: checker override, informed block, surfaced checker output,
  stamp-before-override.

portfolio-optimiser-claude

Sibling implementation of the portfolio-optimiser method on the Claude Agent SDK (decision D7). An open, generic Python framework that finds cost savings inside each project in a portfolio of independent projects: agents generate candidate measures, a mandatory deterministic validator gates the numbers, domain experts judge via HITL, and the system learns from the verdicts.

The method itself is framework-neutral and lives in portfolio-optimiser-commons (consumed here as a git subtree under shared/): the method spec, the OKF bundle navigation contract, the golden/conformance suite (the only oracle for the validator), and the shared expert-reviewer persona skill. This repo implements that spec on the Claude Agent SDK — it does not reverse-engineer the MAF sibling.

Disclaimer: this is a purely technical framework. The deployer owns DPIA, risk assessment, and the legal basis for any processing. The framework ships only the technical preconditions (local-only operation, provenance, no silent egress).

Status

Scaffold (S5): repo, contracts, and shared core in place — no agent runs yet.
