A Record Crosses Town

Deterministic preset · seed 1104

The terminology dependency is unavailable

A simulated 503 triggers bounded deterministic retry and then dead-letter.

Why it stopped

Terminology Service returned simulated 503 for all three allowed attempts.

What recovery may change

Exactly one selected authored condition, followed by replay of this failed hop. The journey is never reset.

Failure is stopped and inspectable.

Bounded recovery

Change one condition. Replay one hop.

The controls call the same deterministic reducer as the authored traces. Applying a condition does not advance the route; replay starts at the failed boundary.

Choose one authored recovery condition

No reset: 5 completed scene(s), 1 retained failure record(s), 5 audit event(s).

Negative evidence

Forbidden effects are checked, not assumed.

Each line is calculated from the stopped checkpoint and current replay state. “Not observed” is scoped to this synthetic deterministic run.

  • unbounded retry

    Highest recorded attempt: 3; exhausted work is retained in 1 dead-letter record(s).

    Not observed
  • clinical write before semantic validation

    SHR artifact delta since the stopped checkpoint: 0. Original failure record retained: yes.

    Not observed
