As Decided Sentry

Deterministic code enforcement for engineering decisions.

Sentry checks machine-readable constraints carried by your decision artifacts against the source changes in a pull request. It supports required and forbidden patterns, import boundaries, full-tree certification, and SARIF annotations—without embeddings, network calls, or an LLM judge.

Use it

name: Sentry

on:
  pull_request:

permissions:
  contents: read
  security-events: write

jobs:
  sentry:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0
      - uses: asdecided/sentry@v0.26.0

By default, Sentry checks added lines against the pull request base and uploads one SARIF report to GitHub Code Scanning.

Use full: "true" to certify the complete repository tree:

      - uses: asdecided/sentry@v0.26.0
        with:
          full: "true"

Decision constraints

Add a Code Constraints block to an accepted decision:

version: 1
eligibility: eligible
reason: "The dependency boundary is deterministic and repository-local."
rules:
  - id: domain-has-no-database-driver
    kind: forbid_import
    path_glob: "src/domain/**/*.rs"
    pattern: "^(sqlx|diesel)(::|$)"
    message: "Domain code must not import a database driver."

Supported rule kinds:

• forbid_import
• forbid_pattern
• require_pattern

Sentry deliberately has no model-judged escape hatch. A decision is either enforced through a deterministic rule, explicitly ineligible, or visibly unclassified.
