Read the standing list. Identify the cycle's axes from + the spec + most recent iter commit bodies + `axis_hints`. +2.

Tasks + that work: small algorithms, single-purpose programs, a + typical consumer-of-the-library API call, a small + transformation pipeline. Tasks that do NOT work: a + one-liner that exercises a single primitive (too thin) or + a large multi-module application (too thick). +3. Total: 2-4 examples. + +### Phase 2 — Implement each example as a downstream consumer + +For each example, in this order: + +1. Draft the program / task in the project's canonical + authoring or consumer form (whatever a real user would + write — surface-language source for a compiler, a Rust + consumer crate for a library, a CLI invocation for a + tool, etc.). Reach for the cycle's new surface where it + fits naturally — but do not contort an example to use a + feature that doesn't fit. +2. Save under `paths.fieldtest_examples` with a name + like `__.`. +3. Run the project the way a user would. Record the exact + commands, the exact output, the exact errors. +4. Record verbatim: + - what you wrote first, + - what each step said, + - the actual stdout vs. expected stdout, + - any moment you reached for something that didn't exist + or produced an unhelpful diagnostic. + +If a step fails, the failure is the data. Do **not** simplify +the example to dodge it. The only reason to abandon an +example mid-way is if the failure is clearly an +`infra_blocked` issue (e.g. the project's CLI binary +missing); in that case return `BLOCKED` with the cause. + +### Phase 3 — Canonical authoring form only + +Every fixture stays in the project's canonical authoring or +consumer form. Do NOT hand-author intermediate +representations, ASTs, internal serialisations, or any other +form that the project's pipeline would normally derive from +the canonical form. If you find yourself about to write such +a sidecar, stop — the project's pipeline derives those +representations from the canonical form; an end-user does +not. + +### Phase 4 — Classify findings + +Each finding is exactly one of: + +| Class | Meaning | +|-------|---------| +| `bug` | Project misbehaves vs. its design ledger. Panic, segfault, wrong stdout, schema break, diagnostic that names a wrong location. | +| `friction` | The task completed, but the surface forced redundancy, awkward order, or a verbose dance the cycle's brainstorm spec implied would be cleaner. | +| `spec_gap` | The design ledger does not constrain the case; you guessed; the project picked a reading; another reading was equally plausible. | +| `working` | The new surface was reached for, used, and the result was correct on first or second try with a clean diagnostic. Worth recording — these are the wins. | + +Borderline items get split into two findings (one per class), +not merged. + +### Phase 5 — Write the spec, hand back + +Write the fieldtest spec under `paths.spec_dir` with a name +shape per the project's naming convention. Use the spec +template below. Leave all artefacts (the fixtures and the +spec file) in the working tree as unstaged changes.

Spec gaps are reported, not patched. +- Edits to anything under `paths.code_roots` or + `paths.bench_dir`. +- A `friction` finding without a 1-line recommendation. + Every finding is actionable or it isn't a finding. +- An "all-clean" report on a cycle that touched user-visible + surface without at least 2 examples in the working tree. + The empty report is a valid status only if no examples + were applicable — and that itself is a `spec_gap` finding. + +## Common Rationalisations + +| Excuse | Reality | +|--------|---------| +| "I'll peek at the implementation to understand why this compiled" | Peeking ends the test. The downstream consumer cannot peek. If the public interface does not explain it, that is a `spec_gap`. | +| "I'll hand-author an intermediate-representation file so the harness picks it up" | The intermediate representation is the project's job to derive. Hand-authoring it is implementation-side; end-users don't do it. The canonical authoring form is the only fixture form. | +| "Diagnostic is unhelpful but I figured out the fix; example is fine" | The diagnostic being unhelpful is the friction. Record verbatim. | +| "I'll silently change the example to one that works" | The non-working case is the finding. Keep the example, record what failed, pick a *different* additional example if you want a working one too. | +| "The design ledger is fuzzy on this corner, I'll pick the natural reading and proceed" | Pick the reading, RUN the example, AND record `spec_gap` with the reading you picked and why another reading was equally plausible. | +| "Bug found — I'll just fix it now, faster than handing off to debug" | Fix-in-place violates the skill split. The fix lands in a separate, RED-tested commit via `debug` → `implement`. | +| "Two examples both ran clean, no findings — short report" | A clean run is itself a finding (`working`). Record what was reached for, what diagnostic showed up when wrong, what was easy. Wins protect the feature from drift. | +| "Three examples is enough, I'll skip the fourth axis" | Each axis the cycle touched needs at least one example. Skipping an axis silently turns the field test into a partial signal, which is worse than no signal because the orchestrator will read it as full coverage. | + +## Red Flags — STOP and re-read the public interface + +- About to open any path under `paths.code_roots` or + `paths.bench_dir` +- About to open an implementation-source file at all +- About to hand-author an intermediate representation, + internal serialisation, or any non-canonical fixture form +- About to silently shrink an example to make it work +- About to merge a `bug` and a `friction` into one finding +- About to attempt a fix in this dispatch +- About to run `git commit` (anywhere, ever — you never + commit) +- About to write the report without writing the examples to + the working tree first +- About to claim "all working" without recording what was + reached for and what was easy (a `working` finding still + requires a paragraph) +- About to skip Phase 4 self-classification because "the + findings are obviously bugs" diff --git a/templates/project-profile.yml b/templates/project-profile.yml index be5ffa3..98cb385 100644 --- a/templates/project-profile.yml +++ b/templates/project-profile.yml @@ -12,6 +12,8 @@ paths: # design_models: design/models # optional code_roots: [src] # bench_dir: bench # optional + # public_interface: [README.md, docs] # what fieldtester may read; everything else is forbidden + # fieldtest_examples: examples/fieldtest # where fieldtester writes fixtures naming: counter_dirs: []
