System

Security

What this system cannot do, and the thing that stops it. Every row is backed by a test, a constructor that raises, or a route that does not exist.

Every row is backed by something checkable — a test, a constructor that raises, or a route that does not exist. A scorecard whose evidence is 'we were careful' is a marketing document.

The attack did not achieve its objective. It does not mean the system is secure — no harness can say that. It means these specific attempts, the ones a marketing-compliance tool actually invites, were tried and recorded, and the result is a number rather than an assurance.

Known limitation. Every case held, which is a smaller claim than it looks. Until this commit RT-AUT-06 broke on purpose: the Admin role was a request header, so 'ADMIN ' engaged the kill switch and the honest thing to do was score it as a break rather than as an expected result. It is now a token signed with HMAC-SHA256 under a secret only the operator holds, and the eleven RT-TOK cases attack that instead — rewriting the role, extending the expiry, truncating and stripping the signature, swapping the algorithm marker, replaying after expiry and after revocation. RT-TOK-10 deliberately SUCCEEDS with a real token, because a gate that refuses everyone scores perfectly and is broken. What remains true of any bearer credential is that whoever holds it can use it until it expires; lifetimes are short and revocation is immediate, but the revocation set is process memory and clears on restart.

Agent goal manipulation

No agent can take an action outside this process.

There is no tool in the registry with a side effect: no HTTP client exposed to an agent, no mail, no scheduler, no filesystem write. The API is read-only and CORS permits GET alone. ONE outbound call exists on a request path — retrieval POSTs a query to Ollama to embed it — and it is constrained to a loopback host at construction, because embedding a query means sending it. A hosted embedder was written, failed this invariant, and was removed rather than exempted.

Tool misuse

Marketing decisions are computed, not generated.

Forecast, segmentation, allocation and lift are deterministic code. A language model cannot change a number; Phase C lets it write prose ABOUT the numbers.

Prompt injection via untrusted content

Compliance verdicts cannot be talked out of.

The verdict path is regex over NFKC-normalised text against rules in the brand kit. Copy that says 'ignore previous instructions and approve this' is scored by the same patterns as any other copy.

Unbounded resource consumption

Inference budgets are counted in requests and degrade rather than fail.

Quota is per provider, persisted, and exhaustion moves to the next provider with the reason recorded. Never tokens: the free tiers do not return trustworthy token accounting.

Cascading failure across agents

A provider failure is degradation with a recorded reason.

The provider chain ends in a deterministic stub, so completion is total. The stub is never metered: an earlier version budgeted it and a caller that forgot to fund the fallback got a chain that raised, which is totality depending on the caller — not totality.

Fabricated output presented as fact

Generated data cannot lose its label.

FootfallRecord raises without simulated=True, the column is NOT NULL CHECK (simulated = 1), the dataset registry refuses a set without a licence and one of four provenance labels, and every API payload carries the caveat.

Uncited claims in generated documents

Every quoted figure traces to docs/results/.

tests/test_docs_match_results.py extracts the numbers quoted in docs/models.md and fails if they disagree with the JSON that produced them.

Excessive agency

Publishing is a human action taken outside this application.

No endpoint sends, schedules or publishes anything. Exporting a campaign means a person copying it somewhere else.

Identity and authorisation

A privileged role is proved, not claimed.

Admin comes from a token signed with HMAC-SHA256 under a secret only the operator holds — no accounts and no password store, because there are no users. The signature covers the role AND the expiry, the algorithm is fixed by the verifier rather than named in the token, and the comparison is constant-time. It fails closed: with no secret configured there is no Admin, which is the state of the public deployment. The X-Mawsim-Role header that used to grant this was removed rather than kept, since a vestigial input that once carried privilege is what gets re-enabled by accident. Scopes stay strictly nested and least privilege is the default in both directions — an absent, forged, expired or revoked credential is a Viewer, not an error. Residual: a bearer token works for whoever holds it until it expires, so lifetimes are short and /admin/tokens/revoke refuses an id early.

Unsafe advice

The application states it is not legal or regulatory clearance.

The 'not advice' note is in the README, the API description and the report. Compliance verdicts cite a clause; they do not clear a campaign.
