MoleculeStepKeys class abstract final

Metadata keys on a type=step bead — one bead per leaf CapabilityStep.

NO {nodePath} infix anywhere in this namespace — unlike the flat model's grid.cursor.{nodePath}.{field} keys, the bead itself IS the node, so there is nothing left to disambiguate per-key. And deliberately NO rewindCount key (Decided item 7): the incarnation axis is DERIVED, never persisted — live_frontier.dart (R4) layers it into the projected NodeCursor.rewindCount in memory only, every time the effective cursor is computed.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

inherited

Constants

capability → const String

The CapabilityRegistry id this step resolves to.

cooldownUntil → const String

The backoff cooldown deadline (ISO-8601 UTC), unchanged semantics.

crumb → const String

The canonical BeadPathKey.canonical string (R7) — a POST-POUR write, same reasoning as MoleculeCircuitKeys.crumb.

durationMs → const String

Capture-only flow telemetry — the derived finishedAt - startedAt milliseconds.

failureReason → const String

The truncated failure diagnostic (capture-only prose — see truncateReason in domain/session_bead.dart, reused verbatim). Never gates orchestration; nothing that decides what runs next reads this key.

finishedAt → const String

Capture-only flow telemetry — the terminal-transition instant.

kind → const String

StepKind.job or StepKind.daemon, by .name.

path → const String

The engine nodePath coordinate (stepPath-joined — sdk/frontier.dart) — the SAME in-run address space the flat model's cursor already uses. projectMoleculeCursor keys the returned CircuitCursor by this field, and its beadIdByNodePath reverse-lookup resolves it back to this bead's id.

prefix → const String

restartCount → const String

The supervised-restart counter (D-5) — unchanged semantics from the flat model's CursorKeys.restartCount, just re-homed onto the step bead itself.

session → const String

The owning session bead id (the JOIN key; mirrors MoleculeCircuitKeys.session).

startedAt → const String

Capture-only FLOW TELEMETRY (FT-1 parity with the flat model) — never read on a build/orchestration path.

state → const String

The fine StepState name (6-valued). bd's OWN open/closed STATUS is the coarse axis (2-valued) — projectMoleculeCursor falls back to it when this key is absent (a freshly-minted step bead has no fine state yet; that is honest, native "nothing has run" — not a bug to paper over with a stamped default).

stepId → const String

The sibling-unique step id (Decided item 4, Flutter's rule inherited): a swarm member's distinguisher (e.g. the rubric id) IS its step id — never the bare capability role, which a same-capability fan-out would collide on.

swarm → const String

The swarm TYPE this step is a fan-out member of — an OPEN string vocabulary ('committee' first, Decided item 11: never a closed enum, so a new swarm type is new circuit content, not new engine code). Absent for a non-swarm step.
