# Milestone fieldtest — Research artifacts — process & campaign documents (cycles 0106–0109) — 2026-07-04

**Role:** downstream consumer (methodology + campaign designer), public
interface only (ledger C18/C22/C25, glossary, CLI --help + introspection, the
fieldtests/ corpora as shape hints). No `crates/` source read. Build:
`cargo build --release -p aura-cli` (HEAD `01925e06`); project dylib built in
the scaffolded `mrp_lab/`. Real data: local Pepperstone archive (GER40 +
FRA40, 2024-09).

**Milestone Verdict: GREEN** — nameable, diffable, auditable research intent
executes reproducibly into recorded, chartable evidence, end to end. Both
findings are doc-gaps, neither a bug nor a broken contract; no
bug/friction/spec_gap in the milestone's own surface.

## The one continuous scenario

- `mra_1_strategy_smacross.json` (+`_built.json`) — op-script → `graph build`
  → register, content id `597d71…` (stable across sessions).
- `mra_2_process_full_v2.json` — sweep(deflate) → gate → walk_forward →
  monte_carlo → generalize, authored from introspection alone; registered
  `cd9127…`.
- `mra_3_campaign_full_v2.json` — GER40+FRA40, persist_taps [equity,
  r_equity], both emit kinds; validated through all three tiers, registered
  `42edeb…`, run by content id.

## Findings

### F1 [working] Full v2 pipeline closes end to end over two instruments
`campaign run <content-id>` (exit 0) runs sweep(deflate)→gate→walk_forward→
monte_carlo per cell + campaign-scope generalize. Records: sweep `selection`
(deflated_score/overfit_probability/n_trials), gate `survivor_ordinals:
[0,1,2]`, wf `family_id`, mc `pooled_oos` (GER40 `n_trades:1843,
prob_le_zero:0.274`; FRA40 `1272, 0.412`), `generalizations`
(`worst_case:0.04367…, sign_agreement:2`, per-instrument breakdown + `winners`
params). → carry-on.

### F2 [working] Bare-{} envelope + block/metric introspection bootstrap authoring
`process|campaign introspect --unwired mra_bare.json` enumerates every
required slot (campaign names the closed tap vocabulary inline:
`persist_taps (equity | exposure | r_equity | net_r_equity)`);
`--vocabulary`/`--block`/`--metrics` (tags `rankable|gate|generalize|
annotation`) suffice to author both docs. The 0108-F8 R-expectancy tagging is
correct. → carry-on.

### F3 [working] Three tiers, legible degradation
Inside a project: intrinsic + referential + `valid (executable): pipeline
shape and static guards pass`. Outside: intrinsic only + `referential checks
skipped (no Aura.toml found up from /tmp)` (exit 0). → carry-on.

### F4 [working] C1 reproducibility + content-id stability
Two runs byte-identical after normalizing only the campaign-run counter
(`42edebd2-<N>`) and the family-store per-name run index (`…-s0-<K>`, both
mint-fresh per ledger); the R-metric/bootstrap number stream hashes
identically (`cd9ad25…`). Op-script re-hashes to `597d71…`. → carry-on.

### F5 [working] Auditable / navigable / chartable realization
`campaign runs` → `run 0 — 2 cell(s), std::sweep -> std::gate ->
std::walk_forward -> std::monte_carlo`; `campaign runs <id>` dumps the BARE
store line, byte-identical to `campaign_runs.jsonl` (not the
`{"campaign_run":…}` wrapper). `trace_name:"42edebd2-0"` → on-disk
`runs/traces/42edebd2-0/597d719b-{GER40,FRA40}-w0/{equity,r_equity}.json`
(exactly the ledger layout); `aura chart 42edebd2-0/597d719b-GER40-w0`
renders a self-contained page. → carry-on.

### F6 [working] Refuse-don't-guess + no-compile diffability
Bogus process ref → `process 0000… not found in the project store`
(referential, exit 1). Unknown tap → `presentation.persist_taps[1]: unknown
tap "pnl" (taps: equity | exposure | r_equity | net_r_equity)` (exit 1).
Process doc validated as campaign → `the "kind" key must be "campaign"` (the
#193 exact-key prose, exit 1). One-value axis edit (`slow.length` 16→32) →
new content id `ce0de8…`, still `valid (executable)`, no compile/run.
→ carry-on.

### F7 [doc-gap] The documented Aura.toml data-archive root is not honored (as documented)
Glossary (`Aura.toml`: "paths only: the data archive root and the runs dir")
+ `docs/project-layout.md` claim the archive root is an `Aura.toml` path, but
neither names the KEY — and a guessed `[paths] archive = …` has no effect
(every real-data path then resolves the built-in default). The real key is
`[paths] data` (honored end-to-end incl. the campaign path). A consumer whose
archive lives elsewhere cannot configure it from the public surface without
the key name. → tighten docs (RESOLVED same-session: project-layout +
glossary now name `[paths] data`, and the `aura new` Aura.toml template
advertises the commented-out key).

### F8 [doc-gap] Role-6a op-script grammar not CLI-discoverable
`graph introspect` surfaces node vocabulary (`--vocabulary`) + ports
(`--node`) but NOT the op-list verbs (`source/add/feed/connect/expose`) or
their JSON shape; `graph build --help` and `project-layout.md` omit them too.
Authored the op-script only via the fieldtest-corpus shape hint. Orthogonal
to this milestone (role 6a shipped cycle 0088); does not block roles 5/6b
(strategy content ids arrive via C25's id interface), but breaks "author from
introspection alone" for the upstream input. → document the op grammar
(filed; docwriter territory with the #197 docs half).

Counts: working 6 (F1–F6), doc-gap 2 (F7 resolved same-session, F8 filed),
friction 0, spec_gap 0, bugs 0.
