-// Usage: go test -json ./... | go run .crane/scripts/score.go
-// Outputs JSON with migration_score and progress metrics.
+// score.go -- deletion-grade migration scoring for the APM CLI Python-to-Go migration.
 //
-// Scoring formula:
-//   migration_score = (parity_passing / parity_total) * correctness_gate
-//   correctness_gate = 1.0 if all target tests pass, 0.0 otherwise
+// Usage:
+//   APM_PYTHON_BIN=/path/to/apm go test -count=1 -json ./... | go run .crane/scripts/score.go
 //
-// NOTE: This script must NOT be modified after milestone 1 is accepted.
+// This script implements the deletion-grade framework from issues #78 and #96.
+// migration_score = 1.0 only when ALL of the following gates pass:
+//
+//   Gate 1 -- python_reference_required: APM_PYTHON_BIN must be set and valid.
+//             TestParityCompletionHardGate must PASS. A missing or invalid Python
+//             binary is a hard failure -- never a warning or vacuous pass.
+//
+//   Gate 2 -- go_tests_pass: every Go test in the module must pass. A single
+//             failing non-parity test voids the gate.
+//
+//   Gate 3 -- surface_parity: TestParityCompletionSurfaceParity must pass.
+//             Python and Go command/option/subcommand inventories must match.
+//
+//   Gate 4 -- help_parity: TestParityCompletionCommandMatrix and
+//             TestParityCompletionHelpIdentical must pass. Every public help
+//             and invalid-usage path must match Python.
+//
+//   Gate 5 -- functional_contracts: TestParityCompletionFunctionalContracts
+//             must pass. Supported command behavior must be covered by
+//             black-box Python-vs-Go contracts.
+//
+//   Gate 6 -- state_diff_contracts: TestParityCompletionStateDiffContracts
+//             must pass. Mutating commands must match Python filesystem,
+//             lockfile, config, cache, and generated-artifact effects.
+//
+//   Gate 7 -- python_tests_pass: TestParityCompletionPythonSuite must pass.
+//             The original Python reference test suite must still be green.
+//
+//   Gate 8 -- benchmarks_pass: TestParityCompletionBenchmarks must pass.
+//             Migration benchmarks must run and satisfy the configured guard.
+//
+//   Gate 9 -- no_known_exceptions: the test output must not contain any
+//             "approved exception" log line. Final cutover requires zero exceptions.
+//
+// If Gate 1 fails, migration_score is forced to 0.0 regardless of other gates.
+// Empty or all-skipped test streams also force migration_score to 0.0.
+//
+// The progress field shows the fraction of deletion-grade gates passing
+// (even when migration_score is 0 due to Gate 1 failure).
