RAW .ail.json IS NEVER HAND-AUTHORED. +EVERY FRICTION POINT AND BUG IS RECORDED. NONE IS WORKED AROUND. +``` + +The first clause is the load-bearing one. The whole point of the +field test is to simulate a downstream LLM author who has only the +specification and the example corpus. If the dispatched agent reads +`crates/ailang-check/`, `crates/ailang-codegen/`, or any other +implementation source, the test contaminates: it now reflects what +the code happens to support, not what DESIGN.md promises. The carrier +contract enforces this; the agent's standing reading list re-states +it. + +The second clause exists because `.ail.json` is the canonical storage +form, but `.ailx` is the form an LLM author is meant to reach for. +Hand-writing JSON skips exactly the part of the language we want to +field-test. If the surface form makes a particular pattern painful, +that is a finding — not a reason to drop down to JSON. + +## The Process — five phases + +### Phase 1 — Scope the field test + +The orchestrator collects: +- the milestone identifier and the JOURNAL entries describing what + shipped, +- the milestone's design spec (`docs/specs/.md`) if one + exists, +- a 1-line scope hint per axis the milestone touched (e.g. "23 + shipped typeclass dictionaries: try a Functor and an Eq instance", + "20 shipped prose projection: try one prose-first authoring + workflow"). + +Two to four examples is the right size. One is too few (no signal on +variation); five is too many for one report to stay readable. + +### Phase 2 — Dispatch `ailang-fieldtester` + +Hand the agent the carrier (see Handoff Contract). The agent: +1. Reads DESIGN.md + JOURNAL tail + milestone spec + a representative + slice of `examples/` (to learn the *form* of valid AIL — not the + *content* of the compiler). +2. Picks the example tasks. Each task is a real, named programming + problem (FizzBuzz, polynomial root via Newton's method, JSON-ish + tree depth, BFS over a small graph, run-length encoder, …) chosen + so it exercises the milestone's deliveries without being a + compiler torture-test. Toy problems find toy bugs. +3. For each task: + - drafts the program in `.ailx` Surface form, + - saves it as `examples/fieldtest___.ailx`, + - runs `ail check` and `ail build` and `ail run`, + - records the experience: what the agent reached for, what it had + to back out of, what the diagnostic said, what surprised it, + where DESIGN.md was silent or ambiguous. + +The agent has the `ail` CLI as a black box. It must NOT open +`crates/`, `runtime/`, or any internal source. It MAY read other +`.ailx`/`.ail.json` files in `examples/` to learn the form. + +### Phase 3 — Friction & bug classification + +Each finding is classified into exactly one of: + +| Class | Meaning | Downstream action | +|-------|---------|-------------------| +| `bug` | Compiler/runtime misbehaves vs. DESIGN.md (panic, wrong stdout, misleading diagnostic, schema break). | Hand off to `debug` (RED-test first). | +| `friction` | Compiles and runs, but the LLM-author had to fight the surface to express the thing. Surface clumsy, redundancy forced, mode/clause dance ugly. | Feeds next milestone's `brainstorm` or a tidy iteration's `plan`. | +| `spec_gap` | DESIGN.md does not constrain the case; the agent had to guess.

Worth recording — these are the wins that protect the feature from drift attempts later. | + +### Phase 4 — Self-review the spec + +Before commit, the agent (or the orchestrator on its behalf) checks: +1. **Source-isolation check:** is any finding phrased as "the + compiler does X"?
