`GET /runs/{id}/events` and `GET /runs/{id}/attach` serve a Petri run's
public events and Fabro's platform records as one ordered stream in a
Fabro envelope (`RunStreamItem`: `run_id`, `stream_seq`, `kind`, `id`,
`recorded_at`, `item`), read from the projector's `petri_stream` table.
The cursor is `stream_seq` (`?after=`); the item's own identity (the
Petri `EventId` as `<log>/<seq>/<index>`, or the platform record's seq)
travels beside it for deduplication. A legacy run keeps its envelope on
the same endpoints; the OpenAPI response is the union of the two lists,
and the stream list reports Petri's `EVENT_CONTRACT_VERSION`.
The attached stream follows the projector's commit signal (a wake-up,
with a poll as the fallback) and ends after the platform record of the
run's terminal lifecycle transition, the analog of the legacy stream's
`run.completed`, or a bounded grace after the projection went terminal.
`RunSpec.engine` (`RunEngine`, `PetriAdmission`, `PetriGraphRef`) is
named in the spec and reuses the Rust types. `fabro-client` matches the
union and adds `list_run_stream`, `list_run_stream_page` and
`attach_run_stream`.
A server test attaches to a two-branch parallel run, disconnects once
both branches started, records a platform notice while both branch
scripts run, reconnects from the last `stream_seq`, and checks the
union is the whole stream: every item once, in order, no gap, no
duplicate, the notice between the branch events, and the same as the
paged listing. The Petri scenarios capture their settled projection and
stream as JSON fixtures for the web app under
`FABRO_CAPTURE_PETRI_FIXTURES`.
