One route, two bodies, told apart by schemaVersion. 2 — RunStart: the reporter (@plune-ai/playwright, plune run start, plune run import) opens a run or joins the live one that already carries this externalKey, then streams results to POST /v1/runs/{id}/results and closes it with POST /v1/runs/{id}/events. 1 — RunResult: plune sync uploads a finished eval run in one piece, results included. The dashboard never calls this surface — it reads what has already arrived. That boundary is ADR 0010: Cairn writes files and knows nothing of the platform, the CLI uploads them, and one published package validates both sides of the contract. meta.ciUrl must be an http or https address — any other refuses the start and opens no run; a shard that joins changes nothing of meta. A run counts against the daily quota (a rolling 24 hours, one count however the run arrived: a start, plune sync, a Cairn ingest or a plan launch). A call that would open a run over it answers 429; a shard that joins a live run already carrying its externalKey opens none, spends nothing and is never refused for it. Retrying a schemaVersion 1 upload (#1534, ADR 0053): send an Idempotency-Key header (1 to 128 of letters, digits and . _ : ~ -; the sha-256 of the body in hex is a good one). The same key in the same project with the same body answers 200 with the first answer (id, linked, unlinked) and opens no run, spends no quota; two retries at once make one run. The same key with another body is 422, and nothing is stored. The key lives as long as its run: the purge deletes both. Without the header nothing changes. A schemaVersion 2 body ignores it - its externalKey is the same idea.

/^[A-Za-z0-9._:~-]{1,128}$/

Makes a schemaVersion 1 upload safe to retry. See the description of this operation.

The caller states that expected is everything its source has — the whole suite, not one file or a --grep. When such a run finishes with an empty notRun, every active case that this source (the source of the run’s results) reported before and did not report in this run moves to detached, with the run named as the reason. Manual cases, other sources, in_review and deprecated cases are never touched; a later result on a detached case brings it back to active by itself. Set it only for the run that covers the whole suite (PLUNE_FULL_RUN=1 in the CLI).

boolean
assignees

Who is to run which case (B8-team T4): testCaseId → userId. Filled at launch by assignment: prefer-assignee from each expected case’s assigneeId at that moment — a snapshot, so a case that changes hands later does not rewrite a run under way. Cases nobody holds are absent. May also be sent as is.

sha

The commit the run was made from — run.sha in GET /v1/runs/{id}/summary.

The branch it was made on — run.branch in GET /v1/runs/{id}/summary.

string
ciUrl

The CI run that produced the report — the reporter reads the runner’s own config.metadata.ci.buildHref. Sanitized before it is stored (a credential in a query parameter becomes a marker); set by the shard that opens the run and never changed by one that joins it. The run page links it from GET /v1/runs/{id}/summary.

/^[Hh][Tt][Tt][Pp][Ss]?:///
runner

The tool that reported the run — playwright, or the report format plune run import read — not the machine of the CI; run.runner in GET /v1/runs/{id}/summary.

string
planId

The plan the run was launched from (D33), when it was — what GET /v1/runs?planId= filters by.

string
planSelected

How many cases the plan’s collections selected when the run was launched (#1274); a count taken then, so it does not follow the plan afterwards.

integer
planQuery

The plan’s collections (filter query strings) as they stood when the run was launched (#1274); a copy, so the run still says what it selected by after the plan is edited or deleted.

Array<string>

title

What to call this run in a list. The first shard to declare one wins; a shard that arrives later fills a field left empty rather than overwriting.

string
>= 1 characters <= 200 characters
environment

Where it ran — staging, prod, a preview. Filterable on GET /v1/runs, so two CI matrices read as two histories.

string
>= 1 characters <= 64 characters
labels

How the run is marked — smoke, nightly, a team name. An empty array is how every mark is removed.

Array<string>
<= 32 items
assignment

How configuration.assignees is filled (B8-team T4): none — as sent; prefer-assignee — from each expected case’s assignee now, an empty map when nobody holds any. Not stored: the outcome is. Only the shard that creates the run is heard.

string
default: none
Allowed values: none prefer-assignee
schedule

Save rather than Launch (#1233): the run is created scheduled — its cases wait, more can be added (POST /v1/runs/{id}/cases), nobody marks them — until POST /v1/runs/{id}/events launch, or a start without it that joins by the same externalKey. Ignored by a start that joins a run already there.

boolean
custom

Values of the project’s run fields (#1764), field id → value, set on the run this start creates and checked as a case’s are - a 400 that names the field and the rule. A default fills a field left out. A required run field refuses a run a person makes (manual, mixed) or one that names custom; an automated start that sends none is not refused. A start that joins a run keeps the run’s own values. The values of configuration groups (#1251, fields with role: configuration) are multiplied into the run’s combinations; a 400 refuses more than 25 combinations, a list over 16 384 bytes, and more than 40 000 results to expect (the expected cases × the combinations).

Two refusals share this status, and what to do about them is opposite. Rate-limited — the per-route throttle, or the per-minute request limit of the plan an API token counts by (#1442, #2092): Retry-After carries the seconds until the window rolls over, and waiting that long is the way out. Quota reached — a ceiling on what the project holds (runs in the last 24 hours, test cases, items waiting in the review queue): { error, quota }. A retry straight away frees nothing, so do not loop on it; the message says what makes room — deleting cases, working the queue down, an operator raising the limit — and the run quota, a rolling 24 hours, frees its oldest runs as they age out. Tell the two apart by the body: a 429 whose body has a quota object is a quota, one without it is a throttle. quota carries kind, limit, used, remaining and resetsAt: the figures behind the sentence, and for the run quota the instant its oldest run ages out (#1258). Retry-After is sent on a quota only where there is such an instant (the run quota: the whole seconds, at least 1, until resetsAt); the case, review-queue and project quotas free only by an action, have resetsAt: null, and send no Retry-After. GET /v1/quotas reads the same figures without a refusal.

Seconds until the window rolls over on a throttle; on a quota, until quota.resetsAt — sent only for the run quota, which has one

The API could not take the request now, and nothing was stored: code pool_overloaded — every database connection is busy and the queue for one is long (refused at once, or the wait for a connection ran out); statement_timeout — Postgres cancelled a statement that ran for 60 s. Retry-After carries the seconds to wait (a few of jitter on top, so that what was refused together does not come back together). The CLI waits that long and sends the batch again, then falls back to its file.
