The catalog in Section 5 groups the threats a conforming compiler MUST detect into five classes: unauthorized privilege or scope expansion, unsafe or bypassed sandboxing, injection (template, shell, or subprocess argument), unsafe output and supply-chain routes (including forged execution attribution), and compile-time drift between manifests, mappings, and the rules that reference them.

Such an adversary can impersonate an allowlisted HTTPS service to an unpatched client and replace both an executable and an unsigned checksum served beside it. CTR-011 authorizes destinations; it does not authenticate their operators or attest client distrust updates.

The trusted setup action authenticates AWF and Copilot checksum manifests before consuming asset digests; threat-detect uses compiler-supplied asset digests, and Docker Compose uses compiler-supplied per-architecture digests. Release builds enforce the actual Go toolchain floor independently of `go.mod`. These are bootstrap/runtime controls, not a new `CTR-*` rejection of workflow network declarations.

Nonempty agent-phase lists MUST emit the +standard compiler experimental-feature warning; syntax and behavior may change +without deprecation. + +For a nonempty top-level `skip-if-decision` list, the compiler MUST require the +AWF agent sandbox and validate up to 64 nonblank string questions. Actions +expressions in questions MUST be rejected. Questions MUST be transported as +JSON environment data, not interpolated shell code or host-side decision +steps. Nonempty lists combined with declarative `protected-session-capture` +MUST be rejected: the decision wrapper retains the capture descriptor across +the exec-only boundary, and a skipped invocation cannot supply a verified +protected session. Absent/empty lists MUST preserve existing generated behavior. + +The shared invocation harness MUST evaluate questions inside AWF before every +otherwise eligible initial, retry, resume, or continuation invocation, +including built-in engines, custom-harness overrides, and supported declarative/durable +execution. Deterministic retry, budget, deadline, and nonrecoverable-error +safeguards MUST remain authoritative. Any `deny` MUST suppress the proposed +invocation; otherwise any `allow` or all `unknown` MUST preserve the selected +execution path. API/model unavailability, timeouts, malformed responses, and +evaluation failures MUST abstain without a separate decision retry, additional +decision-model call, or independent workflow failure. + +Harness initialization MUST be recorded before a potentially billable +decision request so startup recovery cannot infer zero usage from a missing +CLI attempt. This initialization marker MUST NOT claim that an agent CLI +invocation occurred; nonrecoverable preflight checks MUST still run first. + +Decision requests MUST use the existing AWF API proxy and its model, network, +credential, budget, and usage policies. Direct-provider fallback and separate +credential discovery MUST NOT be introduced. Runtime `@file` evidence MUST be +read afresh relative to the engine working directory or workspace, confined +to the workspace or `/tmp/gh-aw/agent`, and checked by the existing guarded +regular-file reader. Sensitive paths, links, and oversized/changing files MUST +be rejected; an unreadable reference makes only its question `unknown`. +Imports MUST use the remaining per-question byte budget and account for +question text, evidence metadata, and JSON escaping within a 512 KiB ceiling. +The complete serialized Decisions request MUST be limited to 400,000 UTF-8 +bytes, including input, question definitions, choices, escaped evidence, and +model/request framing. This approximates 100,000 tokens at four bytes per token; +it is not tokenizer-exact. A question exceeding the remaining request budget +MUST abstain without transmission; smaller questions MAY still join the batch. + +Before transmission, questions and file evidence MUST be screened using +configured secret values and common credential patterns. A match MUST withhold +the entire question and its evidence as `unknown` with +`sensitive_content_blocked`; other safe questions retain their existing batch +path. All-blocked batches MUST make no proxy reflection or decision request. +File evidence MUST use JSON-escaped records with reference and byte-count +metadata, with data-only guidance outside the record.
