fieldtest: milestone runway — real-data seam, 4 examples, 6 findings (gate green)
Milestone-close fieldtest for "Runway — real-data ergonomics & honesty hardening". Four curated end-to-end scenarios derived top-down from the milestone promise, run as a downstream consumer against real GER40/EURUSD M1 bars (public interface only; no crates/*/src read): 1. per-instrument pip honesty (#22) — GER40 index pip 1.0 AND EURUSD forex pip 0.0001 both honest end-to-end; AAPL.US/FOOBAR un-vetted refused exit 2, no stdout leak 2. real GER40 M1 open via open_ohlc from aura-ingest ALONE (#80/#81/#92) — no data-server dep, 53173 real bars, C4 O/H/L/C order, ts-window inverse 3. multi-tap ts-join (#93) — two taps at different cadences, 27744 rows, 0 by-ts mismatches; warm-up None rows where a positional zip would corrupt 4. run-registry coherence (#73/#82) — list/rank retired exit 2, families/ family live, two-store Registry read-back + rustdoc Findings: 4 working, 1 friction, 1 spec_gap. - friction: Cell exposes only from_i64/from_f64/... while the side-by-side Scalar is a tagged enum with public I64(..)/F64(..) variants. The natural param-authoring entry point is Scalar (Cell is the hot-path buffer carrier), so the wrong reach is a self-correcting compile snag — ergonomic only. Filed as a follow-up idea. - spec_gap: unknown family id exits 0 empty — ratified into the C18 note in the preceding commit (treat-as-empty contract). Gate verdict: GREEN. All seven axes mapped to a covering scenario and exercised on real bars; both finding classifications and the one material coverage gap were adversarially re-verified. That gap — #22's FX-vetted pip face, untested by the original scenario set — was probed (EURUSD -> sim-optimal(pip_size=0.0001), FX-scaled, not index-mis-scaled) and folded into scenario 1, so the pip promise is demonstrated on both positive faces. Every scenario re-run independently on HEAD before commit. |

feat(aura-engine): Source::resident_records — probe ring residency via the trait
The residency probe was an inherent method on the concrete M1FieldSource, so a Box<dyn Source> consumer could not read it without downcasting (the adjacent friction noted in #95). Hoist it onto the Source trait as resident_records(&self) -> Option<usize> with a default of None, mirroring bounds()'s Option-for-unknown idiom: None = "does not report" (the eager VecSource, which has no streaming ring), distinct from Some(0) = "reports, holds none" (e.g. exhausted). M1FieldSource overrides it to return Some(chunk len). Callers updated (streaming_seam, the two deep-dive fieldtest bins). Tests: a hermetic VecSource default-is-None check, and a &dyn Source probe in the gated residency test proving M1FieldSource residency is readable without a downcast. refs #95 |

fieldtest: milestone the-world-orchestration-families — 4 examples, 4 findings
Milestone-close gate for "The World, part II — orchestration families".
Four end-to-end scenarios derived top-down from the milestone promise,
each built from HEAD and run as a downstream consumer through the public
API + CLI only (no crates/*/src read):
- mw_3 (headline): real EURUSD-M1 walk-forward composing all four axes
(grid sweep + optimize in-sample, OOS stitch) over the M1FieldSource
seam + lineage — 5 windows, 145 200-pt stitched curve, C2 held.
- mw_2: monte_carlo over 128 seeds, reproducible McFamily (C1) + aggregate.
- mw_1: random sweep -> optimize -> 64-member lineage round-trip.
- mw_4: family-lineage CLI transcript.
Findings: 4 working (promise empirically delivered), 1 bug, 3 friction.
- bug F5: `aura runs list`/`rank` cannot read a pre-0047 runs.jsonl — the

fieldtest: cycle-0049 — 4 examples, 7 findings
Public-API field test of the random param-sweep surface, from a standalone downstream-consumer crate (path-deps only; the public interface = ledger + glossary + spec 0049 + cargo doc rustdoc; no crates/*/src read). Four bins, each built from HEAD and run: continuous tuning (200-point random tune ranked by total_pips), the typed validation gate (all five reachable SweepError variants pre-run), reproducibility + seed-sensitivity + the full i64::MIN..=MAX sampler edge, and Space-trait interchangeability (one tune_and_rank<S: Space> over both GridSpace and RandomSpace). Findings: 0 bugs, 4 working, 2 spec_gap, 1 friction. The four working findings confirm the cycle's acceptance criterion empirically — the headline tune reads as the code a researcher would write, the gate is precise and fires before any run, the C1 reproducibility promise is checkable in one line, and the Space trait delivers one-consumer/both-enumerations. Triage of the actionable findings: - friction (no named-axis builder for RandomSpace — positional Vec<ParamRange> must align with param_space() by hand, and a same-kind transposition passes validation silently): filed as a feature for a future cycle, refs #79 (a RandomBinder sibling to the grid's SweepBinder). - spec_gap (SweepError rustdoc summary named only GridSpace): fixed inline in a follow-up doc commit. - spec_gap (NonNumericRange / Bool-slot ranges unreachable with the shipped aura-std node roster — no node declares a Bool/Timestamp knob): RATIFIED as intentional. The variant is a forward-looking structural guard for the C16 "author your own node" path (a Bool/Timestamp param-slot a custom node may declare); its current untriggerability with the standard roster is expected, not drift. refs #79 |

fieldtest: cycle 0031 node-naming — naming cure under-signposted on the by-name flow
Per-cycle fieldtest of node-instance naming (#56), driven as a downstream consumer from the public interface only (ledger + spec + rustdoc + CLI; no crates/*/src read), three fixtures built and run from HEAD. Verdict: the core 0031 promise holds first-try. A consumer authors Sma::builder().named("fast"), inspects param_space() (sma_cross.fast.length), binds by name and runs; the default-name case (sma.length / exposure.scale, verbatim lowercase) and paramless-interchangeable-stays-legal both hold. 0 bugs, 3 working, 2 friction, 1 spec_gap. The one real gap (verified by the orchestrator against the fixture output): the spec's headline forcing function IndistinguishableFanIn does NOT reach an author on the canonical .with(...).bootstrap() flow. An un-named 2-SMA cross emits a literal DUPLICATE knob (sma_cross.sma.length x2); the binder resolves names before the compile fan-in check, so the author hits UnknownKnob / AmbiguousKnob("sma_cross.sma.length") — which point at the knob, not at the cure "name your nodes". IndistinguishableFanIn only surfaces via the positional compile_with_params path. Rejection still happens (no invalid blueprint runs), so it is an ergonomic/signposting gap, not a correctness bug. Routed to the backlog (relates to #58); 0031 stays audit-closed. Minor: FlatGraph/Harness lack Debug, so a bootstrap Result can't be {:?}-printed. |

fieldtest: milestone the-world param-space & sweep — green, delivers promise
Milestone-scope fieldtest (closing functional gate) for "The World —
parameter-space & sweep" (issues #30-#36). Three curated end-to-end scenarios
derived top-down from the milestone promise, driven from the public interface
only (ledger + specs + rustdoc; no crates/*/src read), built and run from HEAD
via a downstream consumer crate.
Delivery verdict: GREEN. The milestone delivers its promise.
- mw_1 single run bound by name: .with("sma_cross.fast", 2).bootstrap() binds
and runs (12 equity rows); diagnostics precise and knob-named (UnknownKnob /
AmbiguousKnob / KindMismatch).
- mw_2 named-axis sweep + compare: .axis(..).sweep(run) yields a 4-member,
ordered (odometer), disjoint, non-constant SweepFamily; ranking from public
fields. CLI (aura sweep / aura runs rank) delivers the same with no Rust.
- mw_3 structural-constant negative space (deliberate): SMA2-entry's
definitional `2` has no honest expression today -> grounds #55. Out of
milestone scope; not a blocker.
Findings: 0 bugs, 2 working, 3 friction, 1 spec_gap. Verified independently
(re-ran all three from HEAD; confirmed a plain SMA-cross emits sma_cross.length
twice and the shipped CLI sample carries the fast/slow ParamAlias overlays).
Friction (routed to the forward queue, none blocks the gate):
- the promised sma_cross.fast/.slow names are not free — they require
author-added ParamAlias overlays, doubly mandatory because the canonical
2-SMA cross also will not bootstrap without them (IndistinguishableFanIn);
- the sweep closure drops back to positional bind + manual name re-zip.
spec_gap -> #55: the wished-for structural-constant consumer code is recorded
in mw_3 as #55's acceptance evidence.
This commit is the milestone fieldtest itself; it closes no issue. Closing the
tracker milestone stays a deliberate manual act on this green gate.

feat(aura-engine): name the composite boundary — input roles + param aliases
Brings the other two composite-boundary edge-kinds to the named-projection shape #40 gave outputs. input_roles changes from a bare Vec<Vec<Target>> to Vec<Role { name, targets }> (rendered [in:<name>]); a composite gains params: Vec<ParamAlias { name, node, slot }> that relabels an interior leaf param slot's surface name in param_space() (rendered [param:<name>]). Param aliasing is a PURE NAMING OVERLAY, not curation (the load-bearing decision, per spec 0019): every interior param slot stays in param_space() and sweepable; the alias only relabels in place, never reorders or hides. Proven empirically — the MACD run is byte-identical (total_pips 0.1637945563898923, 3 sign flips), only the param labels improved: param_space() now surfaces [macd.fast, macd.slow, macd.signal] instead of three indistinguishable macd.length, and the manifest reads ema_fast/ ema_slow/ema_signal. C23 honoured: role/param/output names are non-load-bearing debug symbols dropped at lowering; identity is positional (role index, param slot, output field). compiled_view_golden is byte-identical (verified: the golden region is untouched in the diff). An out-of-range alias (missing/ non-leaf node or slot past the leaf's param count) is rejected at compile_with_params as BadInteriorIndex, mirroring the output range-check (no new variant). Orthogonal to #36 — purely additive at the composite level. Aliasing is demonstrated on the CLI MACD site only (the spec's worked example + a new E2E test macd_param_space_surfaces_the_three_named_aliases); sma_cross, the engine test fixtures, and the construction-layer fieldtests get the forced role-name + empty params, so the param_space C23 anchor goldens (param_space_mirrors_compiled_flat_node_param_order + siblings) stay byte-identical. Verification (orchestrator-run, not trusted from the agent report): cargo build/test/clippy --workspace -D warnings all green (engine 66, cli 12); the separate-workspace construction-layer fieldtest crate builds (guards the #42 latent-drift recurrence); compiled_view_golden + MACD determinism unchanged. Two faithful repairs to the plan's literal test/code bodies, no semantic change: the out-of-range test uses .err()/Some(BadInteriorIndex) (the Ok arm Vec<Box<dyn Node>> is not Debug, so .unwrap_err() would not compile), and the inline_composite destructure binds params as `param_aliases` to avoid shadowing the injected `params: &[Scalar]` arg. closes #41 |

fix(fieldtests): port construction-layer fixtures to current authoring API
The four standalone construction-layer fieldtest bins (mc_1..mc_4) no longer compiled: they are their own workspace root, so the engine's `cargo build --workspace` never touched them and two waves of API drift went latent. Two breakage classes, both confined to the fixture files (no engine change): - Stale cycle-0016 authoring. `BlueprintNode::from(<Node>::new(..))` relied on the `From<NodeType>` impls retired in the value-empty migration; only `From<LeafFactory>` survives. Ported to `<Node>::factory().into()` — nodes are value-empty blueprint items, params bound at compile. Knock-on in mc_4 `describe_node`: a blueprint leaf is now a `&LeafFactory` with no pre-build schema, so leaf introspection reports the render label + declared param count (inputs / outputs exist only on the compiled flat node, post-build). - Cycle-0018 (#40) OutPort -> OutField slice drift. `Composite::output()` now returns `&[OutField]`; the mc_4 read sites were still treating it as a single port. Ported to index the record; the walk assertion now also pins the arity (one re-exported field), which is the #40 shape. Faithful ports, not assertion-gutting: each fixture still exercises its axis (composite build+run / miswire render / nested composite / graph introspection), verified by running all four bins to their `OK:` line. One genuine semantic drift flagged in mc_2: the blueprint-view label is now the bare value-empty type ("SMA"), so two same-type leaves share a label and are disambiguated by the slot/edge table; the valued SMA(2)/SMA(4) label lives on the compiled view. The fixture asserts what the blueprint view actually exposes and keeps the load-bearing edge-table observability check untouched. closes #42 |

feat(aura-engine): composite output is a named multi-field record
Replace a composite's single output port (OutPort { node, field }) with
an ordered, named record (Vec<OutField { node, field, name }>). A
composite can now re-export K interior fields as one output; a consumer
selects one via the existing Edge::from_field — the same field-wise
selector that already works for multi-output leaf producers (OHLCV).
Why: multi-line indicators (MACD, Bollinger, Stochastic, Ichimoku) could
not be authored as a composition and re-exported as a unit — only one
line escaped the boundary. The MACD PoC was forced to expose only the
histogram. This lifts the three `field == 0` / `from_field == 0` caps at
the composite boundary (inline_composite nested arm, rewrite_edge
composite arm), range-checking the index instead.
Boundary completion, not an invariant change:
- C8/C7/C4 untouched — one port, one row per eval, K base columns (a
3-line MACD is identical in kind to OHLCV).
- C23 honoured — re-export names live at the blueprint boundary only and
are dropped in the compilat (raw index wiring). compiled_view_golden
stayed byte-identical (the regression guard): no name leaked into the
flat graph.
The MACD PoC now re-exports macd / signal / histogram as a record; the
strategy still trades the histogram, selected via from_field: 2. The
render shows K [out:<name>] markers per multi-output composite (input
roles stay [in:<index>] — naming them is the dependent #41).
Output naming ships with the capability (OutField is born name-ready) so
#41 — composite param aliasing + input-role naming — does not reopen the
type.
Verification: cargo build/test/clippy --workspace -- -D warnings all
green; aura-engine 62 tests (+3 capability, +1 through-run E2E), aura-cli
unchanged-count green; compiled_view_golden byte-identical.
Known debt (out of scope, pre-existing): the non-workspace construction-
layer fieldtests (fieldtests/milestone-construction-layer/mc_1..mc_4)
carry their OutField sweep but still do not compile standalone — they use
the Sma::new / BlueprintNode::from(Sma) API retired in the cycle-0016
value-empty migration, never propagated to these fixtures. Tracked as a
follow-up.
closes #40

fieldtest: milestone construction-layer — 4 examples, 7 findings
End-to-end milestone fieldtest (closing gate) for the "Construction layer" milestone (#12 composites + #13 aura graph render). Four real downstream tasks authored against the PUBLIC interface only (ledger + doc-comments + re-exports + the aura CLI), under fieldtests/milestone-construction-layer/: mc_1 — author a named sma_cross composite, build a Blueprint, compile + bootstrap + run (12 populated equity rows); mc_2 — correct vs fast/slow-swapped cross: labels + graph-as-data differ observably (the headline mis-wire-visible property); mc_3 — composite-nested-in-composite inlines and runs; mc_4 — walk the built graph via the read-only accessors, no engine internals. Roll-up: friction_found, NO bugs. The milestone delivers its core promise — fractal authoring -> compile -> bootstrap -> run, introspection as graph-as-data, and param-carrying labels that make a mis-wire readable. None of the findings block the gate. Findings filed to the forward queue (not fixed here): - #28 (feature) — the headline friction: `aura graph` renders only the built-in sample and the render adapter is CLI-private, so a consumer can't render their OWN graph. Subsumes the reachability of #26 (the nested-render panic is structurally unreachable until the render is parameterizable). Likely next (consumer-project / World) milestone. - #29 (idea) — aura-engine doesn't re-export the scalar vocabulary (ScalarKind etc.) a graph-builder needs; one-crate ergonomics tidy. - #16 (comment) — `aura graph` arg policy (help / unknown-arg) should unify with the still-open `aura run` strictness question. The fieldtester read no implementation source; all artefacts are the consumer crate + the two live render captures (render_clustered.txt / render_compiled.txt, byte-identical across runs). |

fieldtest: milestone walking-skeleton — 3 e2e scenarios, delivers end-to-end
Milestone-scope fieldtest (the functional leg of the Walking-skeleton
milestone-close gate), from the public interface only. Three end-to-end
scenarios, all green:
- the newcomer CLI path: `aura run` -> single-line {manifest,metrics} JSON,
exit 0, byte-identical twice (C1), non-degenerate trace (C22), bad-args ->
exit 2;
- the real-data thread: real AAPL.US 2006-08 M1 bars -> load_m1_window ->
close_stream -> SMA-cross -> Exposure -> SimBroker -> summarize -> RunReport,
deterministic AND populated;
- epoch-ns coherence: C3 normalization holds ingest -> run -> sink.
Roll-up: the milestone DELIVERS its promise end to end (ingest -> one signal ->
exposure -> sim-optimal broker -> pip-equity metric -> structured RunReport,
deterministic, populated) on BOTH the synthetic and real-data paths. 0 bugs.
Headline concern (verified by the orchestrator): issue #19's premise is WRONG at
the shipped SMA(2)/SMA(4) demo config — 21 AAPL.US bars warm the cross and
produce a populated trace (total_pips=-1.5, max_drawdown=65.5, 6 sign flips),
not all-zero. The degeneracy #19 saw was deep-SMA/param-dependent, not intrinsic
to the symbol. #19 to be re-scoped. Other findings: `aura run <junk>` exit 0
(already #16), `aura --help` lands on the exit-2 error path (friction), SimBroker
two-f64-slot order unchecked at bootstrap (documented footgun) — both filed.

fieldtest: cycle-0011 — 3 examples, 5 findings
Per-cycle fieldtest of the aura-ingest ingestion boundary (issue #7), from the public interface only. 3 examples (transpose/normalize core; close_stream -> deterministic harness run with epoch-ns end-to-end; load_m1_window over real AAPL.US 2006-08 bars + None paths), all green. 0 bugs, 0 friction. Two spec_gaps named for follow-up (neither a code defect; both filed to the tracker): - load_m1_window returns Some(empty M1Columns) — not None — for an in-coverage but bar-empty window. The rustdoc's "None if no data in [from_ms,to_ms]" reads bar-level but the realized boundary is file-level (it inherits data-server's file-skip None). A consumer matching None == "no bars" is wrong for the in-coverage-empty case. -> tighten the load_m1_window rustdoc (one line). - AAPL.US (the carrier/integration-test symbol) has only ~21 M1 bars/month, so the SMA-cross never warms and the end-to-end run yields all-zero (degenerate but valid) metrics. The boundary is correct (C2 warm-up); the milestone's shipped demo data is too thin to show a non-degenerate trace. -> weigh against C22's "newcomer sees a populated trace" before the Walking-skeleton close (document expected density or name a denser demo symbol/window). |

fieldtest: cycle-0010 — 3 examples, 6 findings
Public-interface-only field test of the walking-skeleton closing seam (#8): the `aura run` CLI and the reusable aura-std::Recorder sink. A standalone consumer crate (path-deps on the three engine crates, as a C16 project would) drives the real binary as a subprocess and wires Recorder via the raw Harness::bootstrap API. Examples (all built from HEAD and ran green): - c0010_1: drive `aura run` as a downstream CLI/jq consumer — single-line JSON report, byte-identical across two runs (C1), bad-args → exit 2 + exact usage on stderr with empty stdout. - c0010_2: wire Recorder onto Sma(3) via raw bootstrap, drain the mpsc::Receiver — rows match the rustdoc warm-up model exactly. - c0010_3: Recorder over [I64, Bool, Timestamp] — the four-kind claim (never exercised by the CLI's f64-only path) holds, verified from rustdoc alone. Findings: 0 bugs, 4 working, 1 spec_gap, 1 friction. - [spec_gap] `aura run <trailing-arg>` is accepted (exit 0), not rejected — the arg parse keys only on the first token being `run` and ignores the rest. The cycle_scope's "any other or missing subcommand -> exit 2" does not unambiguously cover `run <junk>`; the binary chose the lenient reading. Tracked for a ratify-or-tighten decision. - [friction] verifying the documented {manifest, metrics} JSON nesting needs a hand-rolled string walker — the zero-dep consumer has only to_json() and no typed read-path. Low-priority tidy. Both non-bug findings filed to the forward queue; neither blocks the cycle. |

fieldtest: cycle-0009 — 4 examples, 6 findings
First fieldtest of the run-metrics + manifest report surface. A standalone
downstream-consumer crate (fieldtests/cycle-0009-run-metrics/) path-depends on
the engine crates and exercises the post-0009 surface from the public interface
only (rustdoc + ledger + glossary + project layout, never crates/*/src).
Primary axis empirically met: the north-star "a run emits metrics + manifest"
move is reachable from rustdoc alone — drain two recording sinks -> f64_field ->
summarize -> RunManifest -> to_json, metrics matching the hand model on the first
run, deterministic across reruns.
Findings: 0 bugs, 1 friction, 1 spec_gap, 4 working.
- working x4: north-star reachable from rustdoc; SimBroker firing/slot docs (a
resolved 0007 gap) now carry the example; summarize metric definitions exact
on six degenerate inputs (incl. negative-curve drawdown + flat-as-sign-0);
f64_field panics precise and well-located.
- spec_gap: to_json's JSON key names + {manifest,metrics} nesting are not on
the public surface — a consumer parsing the JSON (C18 registry, the deferred
aura run printer) cannot author against it from rustdoc alone.
- friction: to_json renders whole-valued f64 without a decimal point (3.0 ->
"3"), so one f64 field appears as integer or decimal token within one schema.
Both doc-level findings are the same doc pass and matter mainly for the deferred
aura run (#8) and the C18 registry that will parse this JSON. Spec feeds the next
plan as reference.

(fieldtests/cycle-0008-sum-combinators/) path-depends on the engine crates and
exercises the post-0008 surface from the public interface only (rustdoc + ledger

Primary axis empirically met: the north-star two-signal combine move now uses the
shipped Add (Add::new() dropped in exactly where the 0007 fixture hand-authored
an Add2) — the 0007 boilerplate is retired, end to end through SimBroker to a
deterministic recorded pip curve.
Findings: 0 bugs, 1 friction, 2 spec_gaps, 3 working.
- working ×3: Add2 retired; LinComb weighted/variadic sums exact (<1e-12);
warm-up barrier + empty-weights panic as documented.
- spec_gap: Add/LinComb per-input firing policy (Firing::Any / mode-A as-of
join) absent from the public surface — same class as the 0007 SimBroker gap.
- spec_gap: a fired combinator emits one row per *cycle*, so a heterogeneous
same-timestamp multi-source trace can carry >1 row per timestamp (correct per
C4/C5, undocumented at this surface).
- friction: nested consumer crate still needs the empty [workspace] table
(carried from 0006/0007; #9 closed the docs half; folds into aura new).
Spec feeds the next plan as reference.

1 single-signal quality backtest, end to end (SMA-cross -> Exposure -> SimBroker

3 sim-optimal integration: short-on-falling pays positive pips; pip_size=2 curve
exactly halves pip_size=1
4 north-star combine-two-signals (two MA-cross spreads summed into one exposure)
Findings: 3 working (carry-on), 2 spec_gap, 2 friction.
- spec_gap: SimBroker firing policy + cold-exposure->0.0 warm-up emission shape
not on the public surface (only in the feat commit body).
- spec_gap: SimBroker input slot order (0=exposure, 1=price) only in C10 prose /
commit body; a swapped wiring is not caught at bootstrap (both f64).
- friction: the north-star "combine two signals" move needs a sum/LinComb
combinator aura-std does not ship (hand-authored Add2 in the fixture).
- friction: standalone consumer crate still needs the empty [workspace] table
(carried from cycle-0006; tracked as #9).

fieldtest: cycle-0006 sink recording — 5 examples, 6 findings
First fieldtest of the project. A standalone downstream-consumer crate
(fieldtests/cycle-0006-substrate/) path-depends on the engine crates and

2 fan-out/fan-in DAG, 3-arg bootstrap, run() -> ()
3 two interior streams recorded from one run (the cycle headline)
4 byte-identical recorded output across two runs (C1 determinism)
5 mis-wired recording edge rejected (KindMismatch) at bootstrap
Findings: 3 working (carry-on), 2 friction, 1 spec_gap.
- friction: a nested standalone consumer crate fights the workspace
resolver (needs an empty [workspace] table — Cargo's own hint).
- friction: recorder boilerplate is hand-rewritten per author (C9
deliberately ships no library sink).
- spec_gap: the public surface never states output: vec![] is THE sink
declaration, nor defines a Some return paired with empty output.
