+# Fieldtest — cycle 0110 (sweep dissolution) — 2026-07-04
+
+**Status:** Draft — awaiting orchestrator triage
+**Author:** fieldtester (dispatched by fieldtest skill)
+**Binary exercised:** `target/debug/aura` (workspace built from HEAD
+`2c72996`; project cdylib `liblab.so` built from the scaffolded `lab/` crate).
+
+## Scope
+Cycle 0110 is cycle 1 of the "verb dissolution" milestone (#210). Two
+user-visible changes: (1) the `std::sweep` process block's selection triple
+(`metric`+`select`+`deflate`) became an optional, all-or-nothing selection
+group — omit it for a **selection-free sweep**, permitted only as the
+pipeline's terminal stage; (2) `aura sweep <blueprint.json> --real SYM --from
+--to --axis k=v,…` is now thin sugar over the campaign engine: it
+auto-registers a generated selection-free process document + a campaign
+document (content-addressed) and appends a campaign-run record, printing the
+same member lines as before (member manifests now carry an `instrument`
+stamp). This fieldtest exercises both, plus the two consumer paths the
+selection-free sweep exists for (refusal edges, rank-later).
+
+## Examples
+All fixtures under `fieldtests/cycle-0110-sweep-dissolution/`; the scaffolded
+project is `lab/` (its `runs/` store is kept as evidence, `target/` removed).
+Real data: GER40, Sep 2024 (`--from 1725148800000 --to 1727740799999`).
+
+### c0110_1_explore_sweep.json — selection-free single-stage process document
+- A bare `{"block":"std::sweep"}` pipeline authored straight from
+  authoring-guide §2.
+- Fits scope: exercises the new optional-selection-group surface at its
+  simplest (the omitted group).
+- Outcome: `process validate` → `valid (intrinsic): 1 pipeline blocks`;
+  `process register` → id `78f2d8d7…`, re-register dedupes (one file);
+  stored canonical form is byte-exactly `…"pipeline":[{"block":"std::sweep"}]`.
+  `process introspect --block std::sweep` matches the guide verbatim
+  (metric/select/deflate all "optional"). **Ran, matched expected.**
+
+### c0110_2_smacross_open_op.json (+ built blueprint) — the dissolved verb
+- Unbound SMA-crossover op-script → `graph build` → blueprint with three open
+  axes; `aura sweep <bp> --real GER40 --from … --to … --axis
+  graph.fast.length=2,4 --axis graph.slow.length=8,16 --axis
+  graph.bias.scale=0.5 --name c0110-explore`.
+- Fits scope: this *is* the dissolved verb; a realistic ad-hoc explore-sweep.
+- Outcome: prints 4 GER40-stamped member lines; auto-registers a generated
+  process (`9227c300`, name "sweep", selection-free) + campaign (`46e4f7ef`,
+  raw axis names, GER40, ms sub-range window) and appends one
+  `campaign_runs.jsonl` record; identical re-run **dedupes both documents**
+  (no new files, same ids) while appending a second realization (family
+  suffix `s0-0`→`s0-1`, metrics bit-identical — C1); `campaign runs` lists
+  both. **Ran, matched expected.** (`c0110_2_smacross_op.json`, the *bound*
+  variant, is kept as evidence for finding F3.)
+
+### c0110_3a_metric_only.json / c0110_3a_select_only.json / c0110_3b_* — refusal edges
+- Half-populated selection group (metric-only, select-only); a selection-free
+  sweep followed by a `std::gate` stage, driven to the executor via
+  `c0110_3b_campaign_nonterminal.json`.
+- Fits scope: the two new refusals (all-or-nothing group; terminal-only).
+- Outcome: half-group → clean intrinsic refusal naming the missing slot;
+  non-terminal free sweep → passes intrinsic, refused at the executable tier
+  and at `campaign run` with clear prose, no realization appended. **Ran,
+  matched expected.**
+
+### (Task 4) rank-later over the persisted family — `aura runs family … rank …`
+- No new fixture; consumes the `46e4f7ef-0-GER40-w0-s0-0` family persisted by
+  example 2.
+- Fits scope: the rank-later pattern the selection-free sweep exists for.
+- Outcome: `rank sqn` / `rank expectancy_r` return the 4 members best-first;
+  ranking respects metric directionality (max_drawdown ascending, sqn
+  descending); the rank roster equals the `rankable` metric roster
+  (`win_rate`/nonexistent refused with the known list). **Ran, matched
+  expected.**
+
+## Findings
+
+### [working] Selection-free process document round-trips cleanly
+- Example 1.
+- `process validate` → `process document valid (intrinsic): 1 pipeline
+  blocks, 0 gate predicates`; register id `78f2d8d7…`, idempotent on
+  re-register; stored form is the bare block; `introspect --block std::sweep`
+  output is byte-for-byte the guide's transcription.
+- Working: the new optional group is reachable, authorable from the doc alone,
+  and the introspection self-description matches the ledger/guide.
+- Action: carry-on.
+
+### [working] The dissolved sweep verb generates + dedupes a selection-free campaign
+- Example 2.
+- One invocation produced the generated process `9227c300`
+  (`{"name":"sweep","pipeline":[{"block":"std::sweep"}]}`), campaign
+  `46e4f7ef` (raw axes `fast.length`/`slow.length`/`bias.scale`, `instrument:
+  GER40`, window `[1725236099999,1727726220000]` — a ms sub-range of the
+  request), and one `campaign_runs.jsonl` line. Identical re-run: **no new
+  documents** (same content ids), a second realization (`run 1`, family suffix
+  `s0-1`), member metrics bit-identical. `campaign runs` lists both runs.
+- Working: the sugar→campaign parity, content-addressed dedup, deterministic
+  accumulation (C1), and the additive `instrument` stamp all hold end to end.
+- Action: carry-on.
+
+### [working] All-or-nothing + terminal-only refusals are clear and guide-matching
+- Examples 3a/3b.
+- metric-only → `block std::sweep: slot "metric" without "select" — the
+  selection group is all-or-nothing`; select-only symmetric; non-terminal free
+  sweep → `campaign is not executable: process stage 0: a sweep without a
+  selection group (metric + select) must be the last stage of its process`
+  (same prose at `campaign run`, no realization appended).
+- Working: both new refusals fire at the right tier with comprehensible prose
+  that matches authoring-guide §2.
+- Action: carry-on.
+
+### [working] Rank-later over the persisted family, best-first, roster-enforced
+- Task 4.
+- `rank sqn` orders 1.054 > 0.849 > 0.052 > −0.545; `rank max_drawdown` orders
+  4.22M < 6.16M < 6.57M < 9.14M (ascending — lower drawdown ranked better);
+  `rank win_rate` → `unknown metric 'win_rate' (known: total_pips,
+  max_drawdown, bias_sign_flips, sqn, sqn_normalized, expectancy_r,
+  net_expectancy_r)`.
+- Working: the selection-free sweep's reason to exist (defer selection to a
+  rank-later step) works, and the rank roster equals the documented `rankable`
+  set. (Direction convention noted as F-min below.)
+- Action: carry-on.
+
+### [spec_gap] `aura sweep --axis` requires the `graph.`-wrapped name; the docs teach the raw form
+- Example 2 (works with `graph.fast.length`) vs probe P2 (fails with
+  `fast.length`).
+- `graph introspect --params` prints `fast.length` and the authoring guide
+  (§1) calls that "the raw param-space namespace (what a campaign's axes bind
+  against)". The stored campaign doc also uses the raw form. But the dissolved
+  `aura sweep --axis` accepts **only** the wrapped `graph.<param>` form —
+  discoverable solely via `aura sweep <bp> --list-axes`, which the authoring
+  guide never mentions (the guide does not document `aura sweep` at all; the
+  glossary and `--help` say only `--axis name=<csv>`).
+- Why spec_gap: the public interface documents the raw namespace as canonical
+  and is silent on the wrapper; a consumer following it picks the wrong form.
+  The wrapper leaks the root-composite instance name (`graph`) into the user's
+  axis vocabulary.
+- Recommended action: document (glossary `sweep` + a note in authoring-guide)
+  that `aura sweep --axis` uses the `--list-axes` (wrapped) names, **or** make
+  the dispatch accept the raw `--params` names too. → tighten the design
+  ledger / docs (+ plan if the surface is to accept raw).
+
+### [friction] The wrapped-name refusal mangles the axis the user typed
+- Probe P2: `aura sweep … --axis fast.length=2,4 --axis slow.length=8,16
+  --axis bias.scale=0.5` →
+  `strategy 597d…: axis "length" is not in the param space` /
+  `axis "scale" is not in the param space` /
+  `open param "fast.length" is bound by no campaign axis` …
+- The `#203` first-segment strip consumes the leading `fast`/`slow`/`bias`
+  segment, so the diagnostic names `length`/`scale` — fragments the user never
+  typed as a whole axis — while separately reporting the real params as
+  "bound by no axis". The two same-stripped legs (`fast.length`,`slow.length`)
+  even collapse to a single `length` key. The message never says "a leading
+  segment was stripped as the graph name".
+- Why friction: the task can be completed (use the wrapped name), but the
+  refusal actively misdirects — it names a mangled fragment instead of echoing
+  the input and explaining the wrapper convention. (Same root cause as the
+  spec_gap above; split per the one-class-per-finding rule.)
+- Recommended action: echo the typed axis and/or name the expected wrapper in
+  the refusal. → plan (tidy iteration).
+
+### [spec_gap] Authoring-guide §1 inline SMA-crossover binds `length`, contradicting every id / `--params` / §3 axis it prints
+- Encountered building the sweep blueprint (Task 2); evidence
+  `c0110_2_smacross_op.json`.
+- The guide's §1 worked op-script binds `fast.length=2` and `slow.length=4`
+  and claims (line 72) it matches the on-disk corpus
+  `mra_1_strategy_smacross.json`. It does not: the on-disk file leaves both
+  **unbound**. The bound inline form hashes to `e2be81b2…` with `--params` =
+  `bias.scale` only; the unbound corpus form hashes to `597d719b…` (the id the
+  guide later prints at §1/§3 and the id every campaign example references)
+  with `--params` = `fast.length`,`slow.length`,`bias.scale`. A reader copying
+  the inline example gets a blueprint whose id matches nothing in the guide and
+  whose `fast.length`/`slow.length` are closed — so authoring-guide §3's
+  campaign (axes `fast.length`,`slow.length`) would refuse against it.
+- Why spec_gap: the guide is internally inconsistent, and the underlying rule —
+  that an op-script `bind` *pins a param out of the sweepable space* (not a
+  sweep-overridable default) — is nowhere stated. Note the 0110 audit commit
+  claimed "worked example verified against the live binary"; this §1 example
+  (authored earlier, #197/#208) was not.
+- Recommended action: drop the `bind` from the §1 inline example (or state
+  that binding closes the axis) and document `bind`-vs-axis interaction. →
+  tighten docs.
+
+### [friction] `aura sweep <op-script>` rejects the op-script array with a raw serde error
+- Probe: `aura sweep c0110_2_smacross_open_op.json --list-axes` →
+  `aura: …_op.json: Json(Error("invalid type: map, expected u32", line: 2,
+  column: 2))`.
+- `graph introspect --content-id/--params/register` auto-discriminate the
+  op-script array vs the built envelope (guide §1), but `aura sweep`'s
+  blueprint slot accepts only the built envelope, and the mismatch surfaces as
+  a leaked serde `Json(Error(...))` rather than a house-style
+  "expected a built blueprint; run `aura graph build` first". The guide never
+  says `aura sweep` needs a pre-built blueprint.
+- Why friction: the path completes once you build first, but the diagnostic is
+  an internal-type leak (contrast #162's Display-free-error convention seen
+  elsewhere) and the required build step is undocumented for `aura sweep`.
+- Recommended action: shape-discriminate (as `graph introspect` does) or emit
+  a house-style hint. → plan.
+
+### [friction] Refused dissolved sweeps still register their generated campaign document (store litter, some malformed)
+- Probes P2 (raw names) and P3 (subset axes) both **refused** at the
+  referential tier, yet each left a generated campaign doc in
+  `runs/campaigns/` (`92c66b18…` "c0110-rawname", `b0e3f90b…` "c0110-subset").
+  `campaign_runs.jsonl` correctly stayed at 2 (no realization). The rawname
+  doc is *malformed*: its axes are the stripped/collapsed `{"length":[8,16],
+  "scale":[0.5]}` — a document the tool itself immediately rejects, now
+  permanent in the content-addressed store.
+- Why friction: the sugar registers the generated process+campaign documents
+  *before* referential/executable validation, so a fat-fingered axis pollutes
+  the store with dead (occasionally malformed) documents. Content-addressing
+  bounds the growth (identical bad invocations dedupe), and no realization is
+  recorded, so nothing downstream breaks — hence friction, not bug.
+  (`campaign run <file>` registering before an executable refusal — the Task-3
+  `d10ed054…` doc — is by contrast *documented* register-then-run behaviour and
+  is not flagged.)
+- Recommended action: in the sweep sugar, validate the generated documents
+  (referential/executable) before `register_generated`, registering only on a
+  clean preflight. → plan.
+
+### [friction] `process`/`campaign` intrinsic validate needs the built project cdylib when inside a project
+- Task 1 setup: inside the fresh `lab/` project, `process validate
+  c0110_1_explore_sweep.json` (and register/introspect) first failed with
+  `aura: cargo metadata failed: no cdylib target …`, then after `cargo build`
+  with `aura: project dylib not found … run cargo build`. The very same
+  `process validate` runs **dylib-free outside any project** (probe P1 →
+  `valid (intrinsic)`).
+- Why friction: a std-only process document references no project nodes, so
+  the intrinsic (and referential-over-std) check needs no compiled dylib; the
+  CLI nonetheless loads the project env eagerly for any `process`/`campaign`
+  subcommand once an `Aura.toml` is found. A newcomer following the guide
+  inside a fresh project hits a build wall on a pure-shape check. (Likely
+  pre-existing, not introduced by 0110; the error is actionable.)
+- Recommended action: let the intrinsic tier run before/without the dylib load
+  inside a project, or document that any in-project `process`/`campaign` call
+  requires a built cdylib. → plan or ratify (decide the intended coupling).
+

+# lab — an aura research project
+
+This crate is an aura project: a cdylib of node/strategy blueprints the
+`aura` host loads during research (see the engine's docs/project-layout.md).
+
+- Build: `cargo build` (the next `aura` invocation loads the fresh dylib)
+- Run:   `aura run blueprints/signal.json` (from anywhere inside this dir)
+- Nodes live in `src/`; each is registered in `vocabulary()`/`type_ids()`
+  under the `lab::` namespace prefix.
+- Topology is data (`blueprints/*.json`), node logic is Rust.
