One per-function runtime-coverage finding in runtime_coverage.findings.

Fields

id: String

Per-finding suppression key of the form fallow:prod:<hash> (first 8 hex of SHA-256(file + function + line + ‘prod’)). Hashes the current line, so it changes when the function moves. Use this to suppress one finding.

stable_id: Option<String>

Cross-surface join key of the form fallow:fn:<hash> (fallow_cov_protocol::function_identity_id, hashes file + name + start_line). The same function shares ONE value across findings, hot paths, blast-radius, and importance entries (the per-finding id uses a per-surface salt, so it differs by surface), and across V8, Istanbul, and oxc producers (columns are excluded from the hash). Like id, it changes when the function’s file, name, or start line changes; it is a cross-surface / cross-producer join key, not a line-move-immune one. null when the producing surface (or an un-migrated cloud) supplied no FunctionIdentity.

source_hash: Option<String>

Content digest of the function’s full-span source slice (fallow_cov_protocol::source_hash_for: first 8 bytes of SHA-256 as 16 lowercase hex). Unlike stable_id, this is stable across line moves: a moved-but-unedited function keeps the same value, so baselines can suppress it after a pure line shift. null when the producing surface supplied no source_hash.

path: PathBuf

File path relative to the project root.

function: String

Static function name as reported in the merged coverage result.

line: u32

1-indexed line number the function starts on.

verdict: RuntimeCoverageVerdict

Per-function runtime verdict from the protocol decision table.

invocations: Option<u64>

Raw V8 invocation count. None when the function was untracked (lazy-parsed, worker thread, or dynamic code).

confidence: RuntimeCoverageConfidence

Confidence in the verdict.

evidence: RuntimeCoverageEvidence

Static, test, and tracking evidence behind the verdict.

actions: Vec<RuntimeCoverageAction>

Suggested actions for this finding. Omitted when empty.

discriminators: Option<RuntimeCoverageDiscriminators>

The discriminator inputs that produced this verdict (#321), emitted so an agent can reproduce it and see the confidence cap. None for findings not built from the merge pipeline (e.g. baseline round-trips). Omitted from JSON when absent.
