# Milestone 36 fieldtest — "Self-description: every surface explains itself"

Empirical, binary-only check of the milestone promise: that a deployment-posture
agent with **only** the `aura` binary (no engine sources, no repo docs, no
hand-written bootstrap card) can bootstrap from the surfaces alone.

Every artefact here was produced touching nothing but the release binary
(`d26f0c8`) and what it emits (help text, `aura new` scaffold, introspection
output, error messages). One child dir per scenario; each README states the
property it protects. Full findings + verdict: `docs/specs/fieldtest-m1-self-description.md`.

| dir | axis | outcome |
|-----|------|---------|
| s1_bootstrap_author_validate | cold bootstrap → author → validate | green |
| s2_execution_pulse_idiom     | execution semantics + pulse idiom  | green (1 friction) |
| s3_vocabulary_breadth        | vocabulary self-description breadth| pass (1 friction) |
| s4_document_ramp             | document-first ramp from `{}`      | green (2 gaps) |
| s5_trace_measurement         | trace / measurement path           | dead-end (1 bug, 1 gap) |
