fix(prime): preserve provider admission across restarts by rynfar · Pull Request #225 · pylon-code/pylon

rynfar · 2026-09-01T04:58:23Z

Problem

Provider admission could diverge across restarts and devices. A stopped runtime could be revived by stale ingestion, warning-only providers could be blocked, and mobile outbox sends could lose their durable destination when a synchronized thread disappeared.

Functional fix

Preserve exact provider admission lineage across stop, restart, ingestion, and client reconciliation. Pending stops now survive restart without a new wire status, stale runtime events cannot revive stopped incarnations, provider warning states remain selectable, and missing-thread outbox sends become durable holds with explicit retarget/new-thread and delete paths.

Provider-conflict new-thread recovery now commits a complete composer snapshot in one store transaction. It carries images, generic files, terminal and element contexts, preview annotations, review comments, and the exact original provider/model/mode selection without restoring the obsolete project-switch draft move API.
