Why

Commit 58a9eda runs a continuous embed-backfill pump against the engram. We need to confirm it's safe to leave on by default.

Scope

  1. Confirm the engram route /api/embed-backfill actually exists and responds as the pump expects.
  2. Measure the steady-state load — the pump drives ~32 embeds/min continuously. Confirm that is acceptable for a laptop-class soul (CPU, battery, engram write pressure) over a long session.
  3. If not acceptable: gate it behind a flag (default off, or backfill-then-idle), or disable it.

Acceptance criteria

  • Documented confirmation the route exists + a load measurement.
  • Either "acceptable, left on" with evidence, or a flag/disable landed.
  • Reference commit: 58a9eda.

@tim.lingo Can you confirm the engram /api/embed-backfill route actually exists and responds as the pump expects, then measure the ~32 embeds/min steady-state load on a laptop-class soul? Your call on whether to leave it on, gate it behind a flag, or disable.
