[fullsend-ai-fullsend]

This PR updates the fullsend shim workflow to match the current template in the .fullsend config repo.

The shim content has drifted from the template — this brings it back in sync.

Review

Findings

High

• [protected-path] .github/workflows/fullsend.yaml — This PR modifies a file under .github/, which is a protected path requiring human approval. The PR has no linked issue justifying the change to governance/infrastructure files. While the change is a trivial 2-line addition (YAML document marker and management comment) from an automated bot, protected-path changes always require explicit human review regardless of scope.
  Remediation: Link an issue documenting the template sync policy and why this protected-path change is authorized, or obtain explicit human approval on this PR.

Low

• [edge-case] .github/workflows/fullsend.yaml:3 — The # lint-workflow-size: max-lines=280 directive moves from line 1 to line 3 due to the new --- marker and comment. If the linting tool that processes this directive is position-sensitive, the check could silently stop being enforced.

• [scope-verification] .github/workflows/fullsend.yaml — The PR is labeled as a chore but adds a "do not edit" management comment suggesting automated template management, which may be a structural/process change rather than simple maintenance.

Info

• [formatting-consistency] .github/workflows/fullsend.yaml:1 — The YAML document start marker --- is not used anywhere else in the repository's YAML files. This may be intentional as part of template sync with the upstream .fullsend config repo.

• [documentation-pattern] .github/workflows/fullsend.yaml:2 — The "fullsend managed below - do not edit" comment pattern is new to this repository. No other configuration or workflow files use this convention. See also: [architectural-coherence] finding at this location — the managed convention is not documented in project architecture docs.

• [authorization-inference] .github/workflows/fullsend.yaml — This PR was authored by fullsend-ai-fullsend[bot], suggesting automated template synchronization. The bot's authority and scope are not documented in this repository.
