The host's own clock fires it into a new session that runs unattended — every fire opens its own session and nothing is ever appended to an earlier one. Everything this host could not honour is refused HERE, because creation is the only moment somebody is present to answer. A rule under the five-minute floor, an instant already behind the clock, and a repository nobody has vouched for are all 422: a schedule accepted into an untrusted directory would wake at three in the morning, be refused at everything it tried, and leave an empty morning behind. The clock itself is not on this surface. Due-ness, the sweep's cadence and how a ceiling is spent are the host's own facts; a client asks for a schedule and reads what the host decided. ## OpenAPI ````yaml /en/openapi/v3-current/narya.yaml post /v1/schedules openapi: 3.1.0 info: title: Narya Host API version: 1.0.0 description: >- The contract between the Narya host and every client. One long-lived host runs on your machine and serves this API over a Unix socket in your Narya home. Narya creates the socket owner-only, and file permissions are the whole authorization. There is no password, no token and no TLS. The terminal client and the one-shot command that Lerian ships drive this API, and a client you write drives the same one. Results never arrive on the response of the request that caused them. Submitting a message returns 202 with a turn id. Everything the turn produces streams over GET /v1/events as server-sent events with a typed envelope, and a stream resumes from a Last-Event-ID header. One error envelope: code, title, message, and fields on 422. Codes are NRY- followed by four digits. A paged list answers items, limit and a nextCursor when more remains. Cursors are opaque. servers: [] security: [] tags: - name: host description: The host process itself — version, uptime, mode, store. - name: sessions description: Durable conversation containers.

There is no owner field and its absence is the rule rather than an omission — the host writes the owner from its own identity. required: - repository - prompt properties: repository: type: string maxLength: 4096 description: >- Absolute path of the directory a fire runs in. Somebody must have vouched for it already; one nobody has is refused with the sentence that names the gesture. prompt: type: string description: >- What the fired session is asked to do. Required: a schedule with nothing to do starts a session at three in the morning and does nothing in it. agent: type: string description: The agent recipe a fire runs under. Empty runs the host's default. every: type: string description: >- An interval — "15m", "2h", "24h", "7d". Exactly one of every and at is given. The shortest a schedule may fire on is five minutes, and anything under it is refused naming the floor: an agent turn takes minutes and spends money, so a schedule measured in seconds is an incident rather than an aggressive setting. An interval's first fire is one interval away, never immediately. at: type: string description: >- One absolute RFC3339 instant, fired once, after which the schedule is completed. An instant already behind the clock is refused rather than fired late. ceilingUsd: type: number format: double minimum: 0 description: >- What one fire may spend. Absent takes the operator's configured default, which is why the spend ceiling is on whether or not anybody thought about it. Zero is not absent and is never promoted: it is a schedule that does not fire, which is how one is parked until somebody prices it. examples: - repository: /Users/dana/repos/midaz prompt: read yesterday's failed builds and write the summary every: 24h Schedule: type: object description: >- Work the host's own clock starts, with nobody present. A schedule is durable configuration, never swept: what a fire produces is a session, governed by the rules sessions already have, while the schedule itself stays until somebody cancels it. The owner is written from the host's own identity and is never something a caller names — a fire has to be attributable to somebody who is not there, and an attribution the reader cannot check reads exactly like a true one. required: - id - owner - repository - prompt - rule - status - ceilingUsd - createdAt - runCount properties: id: type: string format: uuid owner: type: string description: Who this schedule's fires are billed to and attributed to. repository: type: string description: >- The directory a fired session runs in. Somebody has vouched for it — creation refuses one nobody has — and the host reads that answer again at every fire, because trust is revocable. prompt: type: string description: What the fired session is asked to do. agent: type: string description: The agent recipe a fire runs under. Absent runs the host's default. rule: $ref: '#/components/schemas/ScheduleRule' status: type: string description: >- active fires; completed is what a single-instant schedule becomes once that instant is spent; cancelled is what a person does to one, and it stops the fires without removing the record; paused keeps the row and stops the fires, which is the difference between changing your mind and changing it back. enum: - active - paused - completed - cancelled ceilingUsd: type: number format: double minimum: 0 description: >- What ONE fire may spend. A hard stop on the turn rather than a price — see setScheduleBudget for what it does and does not bound. Zero means this schedule does not fire. createdAt: type: string format: date-time nextRunAt: type: string format: date-time description: >- The instant a fire is owed at. Absent once a single instant has been spent. A cancelled schedule KEEPS the instant it was going to run at — its status is what stops the fire, and the instant is what somebody reads when they wonder whether they stopped the right one. It is advanced from the moment of the fire rather than from the instant that was missed, which is why a host that was off for three days fires once rather than three times. lastRunAt: type: string format: date-time description: >- When this schedule last CLAIMED an instant. Absent until it has. It is stamped at the claim, before the fire's session exists, so it says when the host last acted on this schedule rather than when work last started: a fire refused for a missing repository or an unpriceable model moves it too, and lastError says which. lastFiredSessionId: type: string format: uuid description: >- The session the last fire created, which is where the morning's reading starts. It may name a session that has since been purged. lastSkippedAt: type: string format: date-time description: >- When a due fire was refused, with lastSkipReason saying which refusal it was. Recorded rather than silent: a skip nobody can read is indistinguishable from a scheduler that stopped working. Written once while the refusal lasts, so it answers "since when", and cleared by any fire that gets through. lastSkipReason: type: string lastError: type: string description: >- How a fire that had already claimed its instant failed to reach a session. The instant stays spent, so this is what the morning reads instead of an unexplained gap. runCount: type: integer minimum: 0 description: >- How many instants this schedule has CLAIMED, including fires that never reached a session. The count is incremented inside the same transaction that spends the instant, which is what makes a fire unrepeatable across a crash — so a fire refused after the claim, or a host that died in the gap before the session existed, is counted here and explained in lastError. A consumer counting SESSIONS wants the sessions themselves, not this. examples: - id: 8f2c1a4e-6b0d-4e2f-9a3c-5d7e1f0b2a4c owner: local repository: /Users/dana/repos/midaz prompt: read yesterday's failed builds and write the summary rule: kind: every everySeconds: 86400 status: active ceilingUsd: 5 createdAt: '2026-09-03T09:00:00.000Z' nextRunAt: '2026-09-04T09:00:00.000Z' runCount: 0 ScheduleRule: type: object description: >- When a schedule fires: a kind and the one parameter that kind takes. Exactly one parameter is ever set. There is no cron expression here and the absence is a decision, not a gap: a cron expression drags a timezone, a daylight-saving policy and a no-match semantics behind it, and an agent turn costs money and takes minutes, so the units that matter are hours and days. required: - kind properties: kind: type: string enum: - every - at x-enum-varnames: - ScheduleRuleKindEvery - ScheduleRuleKindAt everySeconds: type: integer minimum: 1 description: >- The gap between fires, present only when kind is every. Seconds rather than the duration a person typed, because the only arithmetic anybody does with it is addition. at: type: string format: date-time description: >- The single instant, present only when kind is at. It is what the person asked for and stays put after the fire, while nextRunAt is what the clock did. Error: type: object description: >- The single error envelope every operation returns.
