Inject instructions into a proposal

What these results establish
The caller, time, ciphertext, committee and winner checks refused these calls. An injection flag does not make a bid ineligible or lower its score. Model judgments can vary; the committee reviews the text before deciding.
Deployment details and untested risks
These outcomes were recorded on tenders-v1.sealedchoice.testnet. Contract and secret-row owner keys remain active. Their holders can replace the contract or rebind the secret.
Attempt 2, a different evaluator build, is covered by earlier gate evidence and was not rerun here. These outcomes do not cover collusion, false claims, a biased rubric or compromised owner keys.
Run a contract attempt
The recorded tender is complete. Some attempts need an open tender, an evaluated tender, or a pending award. We check the required state and role before asking you to sign.
Connect a testnet wallet to run an attempt. Recorded evidence above is available without one.
