Increase Code Scanning Fixer execution budget

[Copilot]

The Code Scanning Fixer exceeded its 30-minute execution limit after repeated denied local-reader calls. This updates its runtime budget and aligns permitted tools with its cache-inspection instructions.

• Execution budget

  • Increase timeout-minutes from 30 to 40.
  • Update the prompt’s timeout reference.

• Tool allowlist

  • Permit cat and head, which the workflow prompt instructs the agent to use for temporary cache files.

bash: ["cat:*", ..., "head:*", ...]
timeout-minutes: 40

• Fixes [aw] Code Scanning Fixer timed out #58855

Warning

Firewall blocked 2 domains

The following domains were blocked by the firewall during workflow execution:

• api.github.com
• github.com

[!TIP]
api.github.com is blocked because GitHub API access uses the built-in GitHub tools by default. Instead of adding api.github.com to network.allowed, use tools.github.mode: gh-proxy for direct pre-authenticated GitHub CLI access without requiring network access to api.github.com:

tools:
  github:
    mode: gh-proxy

See GitHub Tools for more information on gh-proxy mode.

To allow these domains, add them to the network.allowed list in your workflow frontmatter:

network:
  allowed:
    - defaults
    - "api.github.com"
    - "github.com"

See Network Configuration for more information.

🟡 Changes recommended

The workflow timeout was raised to 40 minutes, but the prompt still uses 30-minute stall-detection/exclusion thresholds that can produce incorrect “stalled” behavior.

Pull request overview

This PR updates the Code Scanning Fixer agentic workflow configuration to reduce premature failures by increasing the workflow execution budget and aligning the workflow’s allowed local shell-reader tools with the prompt’s cache-inspection instructions.

Changes:

• Increase timeout-minutes from 30 → 40 (and propagate the change into the generated .lock.yml runtime/env values).
• Expand the bash allowlist to include cat and head for inspecting temporary cache-memory files.
• Update the prompt’s “Self-Assessment Checkpoint” timeout reference to 40 minutes.

Security / correctness notes

• The prompt still uses 30-minute thresholds when deciding whether an in_progress cache record is stalled (and when to exclude still-in-flight attempts). With a 40-minute timeout, those thresholds can cause false “stalled” reporting and unnecessary skipping.

Validation / scanner results

• Not run in this review environment (static diff review only).
