Interface: EpochLocation

Defined in: src/lib/time-travel/epochs.ts:64

One epoch, located: which log holds its call, where in that log, and what that log folds against.

Properties

basis

readonly basis: FoldBasis

Defined in: src/lib/time-travel/epochs.ts:108

How EpochLocation.source folds. 'log-only' means the recording travelled without its fold base, so anything the log never set reads as absent — servedView.ts turns that into a declared gap rather than an empty view.

---

callIdx

readonly callIdx: number

Defined in: src/lib/time-travel/epochs.ts:85

The call's ARRAY index in EpochLocation.log.

---

callRuntimeStageId

readonly callRuntimeStageId: string

Defined in: src/lib/time-travel/epochs.ts:80

The call-llm stage's runtimeStageId — the llm-turn stop's own id.

---

epoch

readonly epoch: number

Defined in: src/lib/time-travel/epochs.ts:78

The committed iteration at the call. 1-based, and READ rather than counted — a run that pauses and resumes still names its epochs the way the run itself named them.

ONE fallback, and it is a count: when the fold cannot read iteration at all (a recording whose base did not travel, on a run that never re-set it), this is the location's position in run order instead. The tell is EpochLocation.basis / EpochLocation.runBasis reading 'log-only', which is also what makes servedView.ts raise no-fold-base. A view must have some number to be addressed by; this one is the honest second choice, not a claim about the record.

---

hasRunLog

readonly hasRunLog: boolean

Defined in: src/lib/time-travel/epochs.ts:114

false when this recording carries no RUN log at all — a subtree handed in on its own. Every run constant is then unreadable, which servedView.ts declares rather than reads as absent.

---

log

readonly log: readonly CommitBundle[]

Defined in: src/lib/time-travel/epochs.ts:83

The log the call committed to: the run's own under 'dynamic', the turn's inner history under 'dynamic-grouped'.

---

runBasis

readonly runBasis: FoldBasis

Defined in: src/lib/time-travel/epochs.ts:110

The same, for EpochLocation.runSource.

---

runLog

readonly runLog: readonly CommitBundle[]

Defined in: src/lib/time-travel/epochs.ts:89

The RUN's log, always. Run constants (a build-time fact seeded once) are read here, because a grouped turn's inner log never sees them unless the boundary happens to carry them.

---

runSource

readonly runSource: FoldSourceLike

Defined in: src/lib/time-travel/epochs.ts:101

The same, for EpochLocation.runLog.

---

source

readonly source: FoldSourceLike

Defined in: src/lib/time-travel/epochs.ts:99

The fold source EpochLocation.log belongs to — the log PLUS the base it was recorded against. Reads go through it, never through the bare array, so a value seeded before the run (every key of a resumed run) folds from where it actually came from.

---

subflowScope?

readonly optional subflowScope?: string

Defined in: src/lib/time-travel/epochs.ts:92

The sf-llm-call mount this epoch was projected from — set under 'dynamic-grouped' only, and the tell that callIdx is inner-relative.
