Brummel ed1d22bbfa spec: 0025 render root like any composite (slot stubs + role-name entries)
Settled source: issue #49, enabled by cycle 0024 (1b39093, root is now a
Composite with input_roles). The cycle removes the last two render special-cases
the root still carries, both pre-0024 vestiges:

(A) render_blueprint threads stub_ctx: None, so a top-level multi-input leaf
    (SimBroker) renders bare [SimBroker] instead of the #… slot stubs an interior
    leaf already gets. Fix: pass the root composite as stub_ctx (it IS a
    &Composite since 0024); stub_ctx drops its Option (both render_graph callers
    pass &Composite). The existing slot_source/fan_in_identifiers/signature_of
    serve a top-level leaf verbatim — no second stub path (#49 acceptance #3).
    -> [SimBroker(#E,#price)] (#E = exposure producer's signature prefix,
    #price = the source role name).

(B) render_blueprint names root entries source:{kind} while render_definition
    names interior entries by role.name — the marker/stub asymmetry. Fix: build
    root entries from role.name (bound-only filter retained), identical to the
    interior. -> [price] instead of [source:F64], byte-symmetric with how the
    same role renders in a where: definition.

render_compilat is left as [source:F64]: post-inline the role name has dissolved
(C23), only the kind survives — [price] pre-inline / [source:F64] post-inline is
C23 made visible, and compiled_view_golden is the negative control.

Scope: crates/aura-cli/src/graph.rs only. Read-only render (C9),
behaviour-preserving for the run path (C1); no engine change. Grounding-check
PASS (10 assumptions ratified against green tests). Render goldens are the
accepted value-asserted regression; closes #49 on land.

Brummel d6f59d7a52 audit: cycle 0024 (#43, #36) — drift-clean; ledger reconciled to the pre-build signature
Architect drift review (862882b..1b39093): NO code drift, no contract weakened.
C1 (behaviour-preserving: 150 tests green, render goldens byte-identical, no
behavioural assertion altered), C8 (sink output: vec![] preserved), C9/C23
(read-only render touches no eval/build; derive_signature's Box::leak is
cold-path-only, leaked names non-load-bearing) all hold. Regression scripts:
none configured (no-op) — the architect review is the gate.

The only drift was design-ledger prose, anticipated and deferred to this audit
by the plan. Resolved here (fix path, orchestrator-applied — docwriter is barred
from the design ledger):

- docs/design/INDEX.md C8 Guarantee: rewritten — a node's signature (NodeSchema)
  is declared pre-build on the value-empty recipe; the built node implements
  lookbacks() (the one param-dependent sizing quantity) + eval(); schema() is gone.
- INDEX.md C8 cycle-0015 note: Blueprint::param_space -> Composite::param_space;
  the #36 lockstep-debt clause marked closed by 0024.
- INDEX.md: added a C8 cycle-0024 realization (signature lives once on the recipe,
  the signature/sizing split, #43/#36 closed) and a C19 cycle-0024 realization
  (struct Blueprint collapsed into the root Composite; Role.source/runnable-iff-
  bound/UnboundRootRole; FlatGraph as the named compilat). Stale symbol names in
  the dated 0016/0017 notes annotated in place with their 0024 renames.
- aura-std/src/lincomb.rs module doc: Blueprint::param_space -> Composite::param_space.

Ledger-gap (four new load-bearing invariants previously unrecorded) closed by the
two new realization notes. Green baseline re-confirmed after the edits: cargo test
--workspace 150 passed / 0 failed; cargo clippy --all-targets -D warnings clean.

Brummel 1b3909316e feat(aura): node signature lives in the blueprint; collapse Blueprint into Composite
Consolidate the node data structure so every node's signature (NodeSchema:
inputs/output/params) is declared once and exists in the blueprint pre-build,
and dissolve the special "root graph" type. Behaviour-preserving (C1).

Signature vs sizing
- NodeSchema is now the static signature only: InputSpec -> PortSpec{kind,firing},
  with lookback removed. The signature is fully static per blueprint (input
  kinds/firing, output fields, params); LinComb's variable arity is a builder arg,
  not an injected param.
- The one param-dependent quantity, an input's buffer lookback (e.g. Sma's window =
  its injected length), moves out of the signature to Node::lookbacks() -> Vec<usize>,
  read only by bootstrap for sizing. Node::schema() is removed.
- LeafFactory -> PrimitiveBuilder, which carries the full NodeSchema. The built node
  no longer re-declares it: closes the params-declared-twice drift (#36, the 8
  per-node factory_params_match_built_node_schema lockstep tests are deleted — their
  subject is now structurally impossible) and a value-empty recipe exposes its full
  I/O interface pre-build (#43).

Root is just a bound composite
- struct Blueprint is deleted; its compile/bootstrap/param_space methods move onto
  Composite. Role gains source: Option<ScalarKind> (None = open interior port,
  Some = bound ingestion feed). A composite is runnable iff every root role is bound;
  the "main graph" is no longer a category, only the fully-source-bound composite.
  New error CompileError::UnboundRootRole for an open root role.
- BlueprintNode::signature() answers uniformly for both arms: Primitive returns the
  builder's declared schema, Composite derives it from the interior (role kinds in,
  OutField kinds out, aggregated params), pre-build, no build.

compile -> FlatGraph -> bootstrap
- compile validates structure pre-build via signature() (validate_wiring: range +
  kind, returning the same variants as before, so an edge kind fault is now caught
  before any build closure fires) and emits FlatGraph{nodes,signatures,sources,edges}.
- bootstrap consumes the FlatGraph: kinds/firing/output from the carried signatures,
  buffer depth from node.lookbacks(). SourceSpec survives as the flat descriptor.

Renames: BlueprintNode::Leaf -> Primitive, LeafFactory -> PrimitiveBuilder.

Render (aura-cli/src/graph.rs) is migrated compile-only: it takes &Composite, maps
bound roles to the same source-entry shape, so both render goldens reproduce
byte-identical output (no re-capture needed). Render-fidelity tuning is the next cycle.

Verification (orchestrator-run, not agent-reported): cargo build --workspace green;
cargo test --workspace 150 passed / 0 failed; cargo clippy --workspace --all-targets
-D warnings clean. All pinned determinism/run-output tests pass with values unchanged;
no behavioural assertion was altered to go green. 5 new tests assert the signature is
pre-build and uniform, that compile rejects a kind mismatch without building (via a
panicking builder), UnboundRootRole, and lookbacks()/signature arity agreement.

Deferred to cycle-close audit (per plan): docs/design/INDEX.md and some aura-std
module docs still name the old Node::schema()/LeafFactory/BlueprintNode::Leaf/
Blueprint::param_space contracts; prose reconciliation is the architect's at audit.

Brummel c7fc2f6a37 plan: 0024 node signature in blueprint
Five-task, compile-gate-sequenced plan for the behaviour-preserving refactor:
aura-core types (PortSpec/PrimitiveBuilder/NodeSchema/lookbacks) -> aura-std
8 nodes -> aura-engine lib (Composite absorbs Blueprint, signature/derive_
signature, FlatGraph, pre-build validate_wiring, bootstrap reshape) -> engine
tests -> aura-cli/ingest + compile-only render. Per-crate partial build gates;
workspace gate only in the final task. One working-tree unit (committed once
after Task 5 green).

Brummel 78d68fa8ad spec: 0024 node signature in blueprint
Consolidate the node data structure so every node's signature (NodeSchema:
inputs/output/params) exists in the blueprint pre-build, declared once.

- Signature vs sizing split: NodeSchema becomes the static signature
  (InputSpec -> PortSpec, lookback removed); the one param-dependent quantity
  (input buffer lookback) moves to a build-time Node::lookbacks() query.
  Node::schema() is removed.
- PrimitiveBuilder (ex-LeafFactory) carries the schema; the built node no
  longer re-declares it -> closes the params-declared-twice drift.
- Blueprint collapses into Composite: Role gains source: Option<ScalarKind>;
  the root is the fully-bound composite (no "main graph"); new error
  UnboundRootRole.
- compile -> FlatGraph -> bootstrap: FlatGraph carries node + signature in
  parallel; bootstrap sizes from lookbacks(), kind-checks from the signatures.
- Renames: BlueprintNode::Leaf -> Primitive, LeafFactory -> PrimitiveBuilder.

Behaviour-preserving (C1). Render is out of scope beyond compiling (next cycle).

Brummel 862882bc04 audit: cycle 0023 (#48) — drift reconciled; render paths unified
Architect drift review (bb90c42..481172a): no contract drift. C9 (render
reads structure + label()/params()/output() only, never eval), C8 (sink =
zero-output leaf, no special case), C12 (blueprint = root composite is
render-structural only; types stay distinct), C23 (consumer-prefix mirrors
the := binding), #38 (composites stay opaque) — all hold. Three fidelity
items, resolved:

- [high, fixed] spec acceptance over-claimed: the SimBroker slot-stub box read
  as in-scope though the work is deferred. Spec amended — the stub acceptance
  is annotated against #49, the met boxes checked.
- [medium, recorded] no docs/plans/0023: this cycle ran spike→refactor under
  user steering instead of planner→implement, because the edge-label-vs-
  consumer-side fork needed an empirical probe (ascii-dag silently drops edge
  labels on collision) before a placeholder-free plan was possible. A plan
  RECORD (not a task plan) now holds the 0023 slot so the counter pairing
  stays intact and the next cycle takes 0024.
- [low, carry-on] multi_output_field_name's leaf-producer fallback is latent
  and untested (no multi-output leaf in the corpus). Carried as debt.

Regression scripts: none configured (no-op). Build/test/clippy green.
Deferred stub work is tracked in #49 (user-signed).

Brummel 481172ae2e feat(aura-cli): unify blueprint main-graph render through one shared core
render_blueprint and render_definition were two divergent paths: the main
graph drew bare factory.label() leaves and bare edges, the composite interior
drew enriched leaves (params, slot stubs, output bindings). They now delegate
to one shared render_graph over borrowed slices — the blueprint is the root
composite, differing only at the borders (ParamNames::Factory vs Aliases,
Entry unifying SourceSpec and Role, empty OutField list = no bindings).

LeafFactory holds a Box<dyn Fn>, so it is not Clone — an owned root-composite
adapter is impossible; the shared core takes borrowed slices instead.

The main graph now shows what the strategy does: a multi-output producer's
selected field surfaces as a consumer-side prefix ([histogram -> Exposure(scale)]),
mirroring the := output-binding form. Edge labels are deliberately avoided —
ascii-dag 0.9.1 silently drops an edge label it cannot place without collision
(arena_render.rs can_place_label), unreliable in a dense graph.

Deferred: top-level blueprint multi-input leaves render without #-slot stubs
(stub_ctx None) — fan_in_identifiers is still composite-coupled via signature_of.

Brummel 5dd9503e40 spec: 0023 unify blueprint main-graph render
The CLI blueprint main-graph render is a separate, poorer path than the
composite-definition render: bare leaves, bare edges, dropped from_field.
Unify both through the composite machinery — the blueprint is the root
composite, differing only at the borders (sources, factory params, sinks
as zero-output terminal leaves). Harness signature header deferred.

Brummel bb90c42028 audit: cycle 0022 (#46) — drift reconciled; output bindings shipped
Architect drift review (range 69d2094..HEAD), regression gate empty
(no scripts configured). Status: drift_found, all resolved here or queued.

What holds: C8/C23 intact — output_binding folds OutField.name onto the
producer label as a pure render symbol; compiled_view_golden byte-identical,
no name reaches the compilat; the drawn where: graph is now exactly the
computation DAG (false terminals + node-count inflation gone).

Resolved (doc reconciliation, this commit):
- docs/design/INDEX.md: two stale render descriptions brought current —
  the C9/0018 realization said output names render as `[out:<name>]`
  markers; the C19/0017 realization said `[in:k]`/`[out]` port markers.
  Both superseded by the `name := producer` binding form (the `[out]`
  staleness is cycle-0022's; the adjacent `[in:k]` was pre-existing drift
  from 0019/0020 and is reconciled in the same clause while here).
- docs/specs/0022: post-ship note added — its Components/Testing strategy
  under-counted the blast radius, missing the full-render golden
  blueprint_view_golden (forced re-capture, caught at implement).

Queued (not fixed): output_binding's tuple arm `(a, b) := …` is spec'd +
shipped but unexercised (no fixture re-exports >1 field from one node) —
filed as #47 (idea).

cycle 0022 drift-clean after this reconciliation (not a milestone close).

Brummel 3b496883e6 feat(aura): render composite output re-exports as producer bindings
In the blueprint view's `where:` section, a composite's output re-exports
now fold onto their producing node's label as a binding
(`[macd := Sub(#Ef,#Es)]`) instead of each becoming a standalone terminal
node wired from its producer. An OutField re-exports an existing interior
node's value — it is never a new node — so the old form drew false
terminals (MACD's macd line feeds the signal EMA and histogram internally
yet rendered as a dead-end leaf) and inflated the node count by the output
arity (MACD where: 8 -> 6 nodes; sma_cross drops its [cross] stub + edge).
The drawn graph is now exactly the computation DAG; the `:=` prefix is the
visual signal that a node's value escapes the boundary. Input roles stay
standalone entry nodes (no producer to annotate) — the asymmetry is
deliberate.

render_definition drops its per-OutField node+edge loop; a new
output_binding helper yields the `name := ` / tuple `(a, b) := ` prefix.
Pure render layer: C8/C23 untouched, OutField.name never reaches the
compilat, compiled_view_golden byte-identical, MACD run deterministic and
unchanged in metrics.

Test blast radius was wider than spec 0022 §Components / the plan's Scope
note counted: besides the MACD pinning test, four more sites assert a
producer that carries an OutField and so gain the `:=` prefix —
blueprint_view_defines_each_composite_once, the two fan-in identifier
tests, the cli_run integration test, and (missed by the plan, caught at
implement) the full-render blueprint_view_golden. All re-pins are forced
by the design, zero judgement. The output_binding tuple arm is unexercised
by current fixtures (no composite re-exports >1 field from one node).

Verified: cargo test --workspace 0 failed; clippy --all-targets
-D warnings clean.

Brummel 69d20949c0 tidy(aura-engine): single-own alias-validity + shared alias-count anchor
Collapse the two correctness-neutral debt items the 0021 fan-in pre-pass
left behind (architect drift review at cycle close).

Alias-validity: the `BadInteriorIndex` check was raised in two places —
the structural pre-pass `check_composite_fan_in` and `inline_composite`.
Since `compile_with_params` runs the pre-pass over every composite before
any lowering, `inline_composite`'s copy was dead for that error path. The
check now lives in one helper `check_alias_indices`, called solely by the
pre-pass; `inline_composite` drops its copy (and the now-unused
`param_aliases` binding — the overlay is a pure naming layer, unused in
lowering, which is driven by the injected scalar vector).

Alias-count: the per-node `a.node == node` predicate was re-derived in
three spots (signature base, the unaliased-param test, the CLI render
base-length). All three now route through one exported anchor
`aliases_on`, so an alias-semantics change touches one site.

Behaviour-preserving: the full workspace suite is the guard (15+6 cli,
25 core, 69 engine, 6+1+1 ingest/misc, 29 std — 0 failed),
`out_of_range_param_alias_rejected` still green (now raised by the
pre-pass), clippy -D warnings clean. No ledger change (the C9 refinement
landed in 0021).

Brummel 04c2280dd8 audit: cycle 0021 (#44) — drift-noted; fan-in distinguishability shipped
Architect drift review over efbe0f4..3f4d756 (the two un-audited interim
render commits 32ac8a3/b73d707 plus the 0021 fan-in cycle).

Holds:
- C23 intact — the IndistinguishableFanIn check is a construction-phase
  pre-pass; the compilat stays name-free (compiled_view_golden byte-stable).
- C9 boundary clean — signature distinguishability lives at the blueprint
  layer and dissolves at inline; the C9 ledger refinement is accurate and
  in-format.
- Pre-pass placement (before the arity gate, not inside inline_composite) is
  the spec-aligned home, not drift: a no-param compile() of a param-bearing
  composite would hit ParamArity first.

Regression: commands.regression is empty (no gate) — architect is the sole
gate; clean of contradictions.

Debt (correctness-neutral, not blocking) tracked in #45 for a focused tidy
iteration rather than rushed at cycle tail:
- inline_composite's alias-validity loop is now dead for BadInteriorIndex (the
  pre-pass raises it first for every composite).
- per-node alias count is re-derived in three sites (signature_of base,
  leaf_has_unaliased_param, signature_base_len).

Brummel 3f4d756ed2 feat(aura): fan-in input distinguishability — construction constraint + source-derived render
A fan-in node (>1 input) whose colliding sources hide an unnamed configuration
axis is now illegal at construction, and the definition view renders each fan-in
input as a source-derived recursive-signature identifier instead of the
positional, meaningless #A/#B.

The root defect was sma_cross: two Sma into a Sub with unaliased length params,
rendering sma_cross() -> (cross) with two indistinguishable [SMA] and
[Sub(#A,#B)] — the author meant fast vs slow but the identity hid it. Now it
renders sma_cross(fast:i64, slow:i64) with [SMA(fast)]/[SMA(slow)] and
[Sub(#Sf,#Ss)].

Shape (single source of truth for "signature" shared by engine + CLI):
- aura-engine signature_of(): a node's recursive authoring identity — type
  initial + alias initials + each wired input's signature (recursing into
  interior leaves, stopping at named roles/composites at their initial).
- aura-cli leaf_label/fan_in_identifiers: shortest sibling-unique prefix of a
  source's signature, never below its base (type + alias initials); a role-fed
  slot renders its name verbatim (#price); equal-signature interchangeable
  inputs keep the positional letter.
- aura-engine IndistinguishableFanIn: a signature collision is a fault only when
  a colliding source carries an unaliased param (the unnamed axis); param-less
  interchangeable sources (fan_composite's Pass/Pass) stay legal.

Param-aware criterion (refined during design): keeps the blast radius to the
param-bearing alias-less fixtures (sma_cross CLI + engine, the nested fast_slow);
fan_composite and the hand-wired flat fixtures stay green.

Placement decision (deviates from the plan): the constraint runs as a structural
pre-pass (check_fan_in_distinguishability) at the head of compile_with_params,
BEFORE the param-arity gate — not inside inline_composite as the plan drafted.
Reason: the no-param compile() of a param-bearing composite would hit ParamArity
first and preempt the fault; the spec mandates a structural check needing no
param values, so the pre-pass is the spec-aligned home. Alias-validity ordering
(BadInteriorIndex before the fan-in fault) is preserved at the pre-pass head.

C23 untouched: the check is construction-phase; the compilat stays name-free
(compiled_view_golden byte-stable). Ledger C9 carries the refinement.

Known debt (non-gating): the alias-index validity check now exists in both
inline_composite and the pre-pass (the pre-pass reaches every composite first,
making inline_composite's copy effectively dead). Left for a separate tidy — a
5-line, correctness-neutral removal with its own test surface.

Brummel 22a690361a spec: 0021 refine fan-in constraint to a param-aware criterion
A signature collision is a fault only when at least one colliding source

unnamed (sma_cross's length). Equal-signature sources with no param are

stay legal; the render uses the positional letter for them. Keeps the
construction blast radius to the param-bearing alias-less fixtures.

Brummel 14d91035ec spec: 0021 fan-in distinguishability
A construction-phase constraint (CompileError::IndistinguishableFanIn, raised in
inline_composite) makes a fan-in node whose sources have identical recursive
signatures illegal; the definition view then renders each fan-in input as the
shortest unique prefix of its source's signature (replacing positional #A/#B);
and the sma_cross fixture gains its missing fast/slow aliases.

Refs #44 — scope extended from render-only to a construction-phase invariant
during design (the positional #A was a symptom of unnamed, indistinguishable
fan-in sources, which is the actual fault to forbid).

Brummel b73d7076c3 feat(aura-cli): TTY-gated ANSI edge colouring + blank line after composite signature
Two presentation refinements to the `aura graph` views, render-only (no
engine change, C8/C9/C23 untouched).

Edge colouring: thread a `Color { Plain, Ansi }` through render_flat /
render_definition / render_blueprint / render_compilat. `Ansi` uses
ascii-dag's colored scanline pass (per-edge palette colours) so crossing
edges stay traceable; `Plain` is the existing monochrome `g.render()`.
The CLI selects `Ansi` only when stdout is a TTY (`IsTerminal`), so a
redirect to a file or pipe stays byte-clean — `aura graph | …` carries no
escape codes. ascii-dag colours only edges; node-label text is unaffected.

Tests render `Color::Plain` explicitly, so both goldens stay byte-stable
(compiled_view_golden remains the C23 guard); a new test pins that `Ansi`
emits escapes and `Plain` does not, and that labels survive colouring.

Blank line: render_definition now separates the typed signature title from
the graph body with an empty line. blueprint_view_golden re-captured.

Considered but rejected this round: per-node role highlighting of the
signature identifiers — needs either an ascii-dag fork (node colouring is
hard-disabled upstream) or a per-graph string-surgery pass that does not
generalise beyond hand-known labels. Only edge colouring survives here.

Architect drift review over ebe2e71..HEAD (spec 42eb627, plan 71f5033,
impl 2f49165). No regression scripts configured (profile regression/
architect_sweeps both empty) — the architect is the sole gate.

Result: clean. Render-only confirmed against the diff:
- C23 intact — compiled_view_golden is NOT in the diff (byte-identical);
  render_compilat untouched; no role/param/output name reaches the compilat.
- C9 — the new signature/leaf_label/kind_str helpers are pure reads over the
  blueprint (shared borrows of params/nodes/edges/input_roles/output/factory
  params); no mutation, no build.
- C22 honoured — the richer pre-run definition (typed signature + folded
  leaf labels + ordered input stubs, [param:*] markers removed) surfaces more
  authored structure with no run change (aura run --macd unchanged).
- C8/C7/C4 untouched. No ledger change warranted: render specifics live only
  in graph.rs, and the ledger nowhere asserts a pre-build factory output
  interface (the #43 gap is consistent with the ledger, not drift). The
  node.rs LeafFactory::label doc fix (flat renderer since 0017) is accurate.

Two debt-low items carried, not fixed (deliberate over-provision the spec
called "defined for completeness"):
- leaf_label's multi-param `, `-join and both-present `; ` arm are untested
  (no node carries 2 aliased params or a param + >1 input);
- signature's `?` malformed-alias fallback is a defensive non-panic guard,
  unpinned by test.
No dead code, no weakened assertion (the five name:->name( repins are
equal-strength), no lying comment, no stray TODO.

drift-clean, not a milestone close.

Brummel 2f4916596d feat(aura-cli): composite definition renders as a typed signature
Refines #41's blueprint-definition render. The [param:<name>] marker nodes
#41 added bloated the ASCII MACD graph (three extra nodes + fan-in edges);
this moves the interface into the title line and folds names into the leaf
labels that already exist:

Brummel 71f50330db plan: 0020 composite signature render
Two-task render-only plan executing spec 0020:

- T1 (graph.rs + node.rs): add `signature` (typed title line, with a new
  ScalarKind->lowercase `kind_str` match — none exists today, {:?} gives
  PascalCase) and `leaf_label` (fold aliased param names + ordered
  input-slot stubs); edit render_definition (title->signature,
  leaf->leaf_label, drop [param:*] loop, de-prefix outputs); fix two stale
  doc comments (the render_definition [param:] description + the
  node.rs:93-101 cluster rationale). Gate: cargo build -p aura-cli (the
  goldens go red until T2 re-captures; cargo test is NOT a T1 gate).
- T2 (main.rs): repin the FIVE title asserts name:->name( (the blast
  radius: sma_cross/outer/inner/dup/macd, four beyond the spec's named
  one); update the definition needle ([Sub]->[Sub(#A,#B)], [out:cross]->
  [cross]); rewrite the MACD render assertions (drop [param:*], add the

  re-capture blueprint_view_golden wholesale; confirm compiled_view_golden

Brummel 42eb62771d spec: 0020 composite signature render
Render-only refinement of #41's composite blueprint-definition view. The
[param:<name>] marker nodes #41 added bloat the ASCII graph; this moves the
interface into a typed signature title line and folds names into the node
labels that already exist:

- title: macd(fast:i64, slow:i64, signal:i64) -> (macd, signal, histogram)
  (param kinds from factory().params()[slot].kind; OUTPUT NAMES ONLY)
- leaf labels fold aliased param names: [EMA] -> [EMA(fast)]
- unnamed interior input slots as positional stubs: [Sub] -> [Sub(#A,#B)]
  (count/order derived render-side from c.edges() + c.input_roles())
- outputs de-prefixed: [out:macd] -> [macd]; [param:*] marker nodes removed
- fix stale node.rs:93-101 cluster rationale (renderer went flat in 0017)

Output KINDS are deferred: a value-empty LeafFactory exposes no output
schema pre-build (the mc_4/#42 finding), so the typed arrow (-> macd:f64)
waits on #43. Render-only: no engine/ParamAlias/param_space change;
compiled_view_golden byte-identical (C23); aura run --macd unchanged.

Gates green: feature-acceptance (the worked MACD before->after is the
evidence), placeholder scan clean, parse-every-block no-op (no
spec_validation parser), grounding-check PASS (10 assumptions ratified;
both load-bearing premises — no pre-build factory output schema, flat
renderer — confirmed).

Brummel ebe2e71349 audit: cycle 0019 (#41) — drift-clean; C9 boundary-uniform realization note
Architect drift review over 8bc429f..HEAD (spec 03f2dc4, plan c9115e3,
impl 41cbb55; plus the in-range #42 fieldtest port 241bb62). No regression
scripts configured (profile regression/architect_sweeps both empty) — the
architect is the sole gate.

Result: clean. C23 holds — Role.name / ParamAlias.name / OutField.name are
all dropped at lowering; compiled_view_golden byte-identical (untouched in
the diff); the param_space slot-order anchors green and unmodified. Param
aliasing is a pure naming overlay (relabel in place, slot order/arity/kind
unchanged), confirmed by the new relabel/unaliased/partial tests. C8/C7/C4/
C9 untouched (authoring-surface legibility only); BadInteriorIndex reused,
no new variant. The #42 port is faithful (assertions strengthened, not
gutted).

One drift item, resolved here: the 0018 C9 realization note carried a stale
"Input-role and param names ... remain index-only pending #41" sentence.
#41 has landed, so this commit replaces it with a cycle-0019 realization
note recording that all three composite-boundary edge-kinds (input roles /
params / outputs) are now uniform named projections of interior handles
(Role / ParamAlias / OutField), names non-load-bearing and dropped at
lowering — the prose now matches the shipped code.

drift-clean, not a milestone close (no milestone fieldtest run here).

Brummel 41cbb5506f 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.

  re-export, all engine test Composite::new sites. Gate per-crate

  The new params field is dormant -> param_space byte-identical, C23
  anchor goldens green.
- T2 param aliasing RED-first: collect_params alias relabel + inline_composite
  alias range-validation (-> BadInteriorIndex, reusing the variant), with
  4 new unit tests (relabel, out-of-range, unaliased regression, partial).

  site (named role + fast/slow/signal aliases, the worked example);
  sma_cross named role only; blueprint_view_golden re-capture;
  compiled_view_golden stays byte-identical (C23 guard).
- T4 fieldtests sweep (separate workspace root -> explicit cargo build
  gate, guarding the #42 latent-drift recurrence) + full --workspace
  triple (-D warnings).

Brummel 03f2dc4c51 spec: 0019 name composite boundary
Sibling of #40 (composite output as a named multi-field record). Brings
the other two composite-boundary edge-kinds to the same named-projection
shape: input roles (Vec<Role { name, targets }>, rendered [in:<name>])
and a param-alias overlay (Vec<ParamAlias { name, node, slot }>) that
relabels an interior leaf param slot's surface name in param_space().

Load-bearing decision recorded in the spec: param aliasing is a pure
naming overlay, NOT curation — every interior slot stays in param_space()
and sweepable; the alias only relabels in place, never reorders/hides
(forced by the issue's "legibility not capability" framing + C23). The
injected point vector is unchanged; MACD surfaces macd.fast/slow/signal

Brummel 241bb626e6 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.

Brummel 8bc429f367 audit: cycle 0018 (#40) — drift-clean; C9 multi-output realization note
Architect drift review over a4cfe5c..HEAD (covers the previously-unaudited
EMA node and MACD PoC plus the #40 composite multi-output cycle): status
clean. C8/C7/C4 preserved (one port, one row per eval, K co-fresh base
columns — structurally identical to OHLCV); C23 honoured (ItemLowering::
Composite.output is Vec<(usize,usize)>, no name in the compilat; the
compiled-view render stayed bit-identical). EMA and MACD PoC carry no
ledger drift.

Resolution of the three minors:
- Ledger lagged the new behaviour: added a "Realization (cycle 0018)" note
  under C9 recording that a composite's output is now a named K-field record
  (Vec<OutField>), the same arity C8 already grants a leaf, names dropped at
  lowering (C23). Amended here (ledger amendment is the audit's job).
- blueprint.rs module-doc / Composite struct-doc / new-doc still said "one
  output port" singular — updated to "output record".
- Non-workspace fieldtest From<Sma> debt is pre-existing (cycle-0016) and
  already tracked as #42; not re-filed.

No regression scripts configured (profile regression: []), so the architect
review is the sole gate. Carry-on: the next natural iteration is the #41
legibility sibling (input-role + param naming at the composite boundary).

Brummel 784e6c917a 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.

Brummel d8b2a2880d feat(aura-cli): MACD strategy PoC over the EMA node
Author MACD as a nested composite -- price -> fast/slow EMA -> Sub (MACD line) -> signal EMA -> Sub (histogram), the histogram exposed as the single output the strategy trades. A richer fixture than sma_cross: an EMA-of-EMA chain with interior fan-out (the MACD line feeds both the signal EMA and the histogram), exercising the nested-composite render shipped in cycle 0017.

It runs over the real path: the composite blueprint is compiled to a flat harness via compile_with_params + Harness::bootstrap (the same machinery as the SMA compiled view), not hand-flattened. New surfaces: aura run --macd (runs the strategy, prints metrics) and aura graph --macd [--compiled]. main's arg parsing is rewritten to a whole-argv match, preserving the #16 strict contract (trailing token / unknown subcommand -> usage, exit 2). MACD gets its own longer synthetic stream because the SMA-seeded EMAs warm up; the SMA sample's stream and goldens are untouched.

This PoC makes two parameter-space gaps concrete for the milestone: the strategy's param_space is [macd.length, macd.length, macd.length, scale] -- three identical names distinguishable only by slot (the named-param case, blueprint #30) -- and a composite exposes only one output port, so the MACD/signal/histogram tuple cannot all be tapped for display (the tuple-output case). The compiled view's valued labels (EMA(2)/EMA(4)/EMA(3)) are what currently disambiguate the three EMAs.

Tested: MACD compiles from the nested composite and runs deterministically (C1), the trace is non-trivial (>=1 exposure sign flip), and the blueprint view renders the composite definition once.

Brummel ae1d4564f5 feat(aura-std): EMA node (SMA-seeded, O(1) per cycle)
Add Ema, the std-lib's first recursive/stateful producer: exponential moving average with alpha = 2/(length+1). The building block MACD (and DEMA, MACD-histogram, etc.) needs, and a worked example of a node whose param sizes its math, not its input window.

Seeding is ratified as SMA-seeded (ta-lib convention): the EMA stays silent until it has seen length samples, seeds with their SMA, then runs the recurrence. Chosen over a first-value seed for three substantive reasons -- warm-up consistency with Sma (both emit None until length samples), parity with the EMA traders expect (ta-lib MACD seeds this way), and statistical honesty (no average claimed from a single observation). A first-value seed was the proof-of-concept convenience; rejected.

Performance: recursive state means lookback = 1 (length sizes alpha, not the window); eval is O(1) time and state via ema += alpha*(x - ema), with no hot-path allocation (the output buffer is reused).

Tested: warm-up-then-smooth (a step input separates it from a plain SMA), length-1 identity, label, and factory/schema agreement.

Brummel a4cfe5c53f audit: cycle 0017 (#38) — render_flat dedup + ledger #38 realization note
Architect drift review of the #38 cycle (a70c5fa..cd31447) against the design
ledger. No ledger-contract drift: C23 holds (render_compilat byte-identical,
compiled_view_golden green), C9/C12 honoured (the new main-graph + where:-
definitions view renders a composite as an opaque authoring-level node with its
body defined once — a faithful blueprint/source view vs. the inlined compiled
form), the nested-composite unimplemented! is genuinely removed and tested, and no
orphaned references to the removed ItemDisplay/producer_id/consumer_ids remain in
crates/ (only frozen historical plan docs mention them).

Two debt items, both fixed here (not carried):

- [medium] crates/aura-cli/src/graph.rs — render_compilat open-coded the same
  Graph::with_mode/add_node/add_edge/render idiom the new render_flat helper wraps.
  Fixed: render_compilat now builds its edge-pairs (its Edge structs + source
  targets) and delegates to render_flat, so render_flat is the single flat-build
  point shared by all three render functions. Behaviour-preserving — same node and
  edge insertion order — verified by compiled_view_golden staying byte-identical.

- [low] the retired cluster-box blueprint-render model and its substantive cause
  (ascii-dag 0.9.1's subgraph /2 centering bug; flat-only being the fix) lived only
  in the superseded spec 0013, not in the durable contract layer. Fixed: added a
  "Realization (cycle 0017 — blueprint render = main graph + definitions)" note to
  the ledger (INDEX.md, under the C22 blueprint-view detail) recording the
  opaque-node + where:-definitions model, the authoring-vs-compiled split, the
  ascii-dag-bug rationale, the scale/render-once/nested benefits, and the #37
  playground (enter/focus) counterpart vs. #38 static CLI form.

regression: profile declares no regression scripts and no architect_sweeps — the
architect review is the sole gate. No baseline to update.

Cycle 0017 is drift-clean after these fixes. NOT a milestone close — that needs the
end-to-end milestone fieldtest, still deferred until the sweep root (#32-#33) lands.

Brummel cd31447d98 feat(aura-cli): blueprint view = main graph + composite definitions (#38)
Rewrite the `aura graph` blueprint view from ascii-dag subgraph cluster boxes to
a "program with subroutines" model: a flat main graph that wires the harness with
each composite shown as a single opaque node, plus a `where:` section that defines
each distinct composite type once (its interior with [in:k]/[out] port markers).
`render_compilat` (flat, fully-inlined, C23) is byte-for-byte unchanged.

Why (not effort):
- Correctness under width. ascii-dag 0.9.1's subgraph level-centering rounds
  sibling x-positions with `/2`, overlapping wide sibling labels (a
  width/parity-sensitive bug with no config/padding dodge that survives
  unequal-width siblings; verified by reproduction). The flat layout is
  collision-free; this view renders only flat graphs, so the bug cannot arise.
- Scale. A composite is one opaque node in the main graph, so blueprint size
  tracks top-level wiring, not inlined node count — real strategies stay
  displayable.
- Render-once. A composite reused N times has its body rendered once
  (collect_distinct_composites dedups by name(), recursively).
- Removes the nested-composite `unimplemented!` — the definitions pass recurses,
  so nested composites render as opaque nodes with their own definitions.

Mechanics: ItemDisplay/producer_id/consumer_ids are gone (a composite is now one
display node, so boundary fan-resolution collapses); new render_flat (the same
no-subgraph idiom render_compilat uses), collect_distinct_composites, and
render_definition. The now-unused `Target` import is dropped.

Divergence from the plan's literal text: the plan's `collect_distinct_composites`
used a nested `if let { if .. }`; this toolchain's clippy (collapsible_if, rust
1.94) rejects it under -D warnings, so it is the behaviour-identical let-chain form
`if let BlueprintNode::Composite(c) = item && !seen.contains(&c.name())`.

Tests: the two cluster-asserting blueprint tests are replaced by four behavioural
tests (opaque-node main graph; defines-each-composite-once; nested-renders-without-
panic; reused-composite-defined-once) plus a recaptured blueprint_view_golden
(captured verbatim from `aura graph`, not hand-authored). The four must-stay-green
tests pass; compiled_view_golden is byte-identical (render_compilat untouched).
Verified: `cargo test --workspace` all green, `cargo clippy --workspace
--all-targets -D warnings` clean.

The interactive enter/focus navigation counterpart is the playground's, tracked
separately as #37.

Brummel 2d3792e45f spec: 0017 blueprint view as main graph + composite definitions
Redesign the `aura graph` blueprint view (render_blueprint) from ascii-dag
subgraph cluster boxes to a "program with subroutines" model: a small main
graph that wires the harness with each composite shown as a single opaque
node, plus a `where:` section rendering each distinct composite type's
interior once. render_compilat (flat, fully-inlined, C23) is unchanged.

Design ratified in-session. The 3a-vs-3b fork was resolved by medium: the
interactive enter/focus model (3a) is the playground's, parked as #37; the
static main+definitions model (3b) is the CLI's, this cycle.

Substance:
- Correctness under width: ascii-dag 0.9.1's subgraph level-centering rounds
  sibling x-positions with `/2`, overlapping wide sibling labels (a
  width/parity-sensitive bug with no config/padding dodge that survives
  unequal-width siblings). The flat layout is collision-free; the new model
  renders only flat graphs, so the bug cannot arise.
- Scale: a composite is one opaque node in the main graph, so blueprint size
  tracks top-level wiring, not inlined node count — real strategies stay
  displayable.
- Render-once: a composite reused N times has its body rendered once.
- Removes the nested-composite `unimplemented!` at graph.rs:74-77 (the
  definitions pass is recursive).

Defaults baked (not forks): composite-type dedup key = name() (assumes
same name => same structure, the authoring convention); opaque-node ports
shown as [in:k] / [out] markers in a definition.

Brummel a70c5faab7 audit: cycle B (0016) — ledger 0016 realization note (C8/C19), debt #36 filed
Architect drift review of the #31 cycle (2a9a141..4b64409) against the design
ledger. The feature is clean: C19/C23 realized literally (LeafFactory recipe;
compile_with_params builds-then-wires slot-by-slot in the same walk param_space()
projects — #34's dual-traversal hazard genuinely subsumed, one traversal, both
mirror tests green incl. nesting); C12 "no recompile per param-set" holds
(value-empty blueprint, vector-bound, bit-identity green); the removed
Composite::schema/BlueprintNode::schema confirmed caller-free.

ledger (fixed here):
- C8: the 0015 note's "binding a value to a slot (#31) ... deferred" line was stale
  (shipped). Updated to record #31 landed in 0016, and that the param declaration's
  authoring home moved to LeafFactory.params() (read pre-build) alongside the built
  node's schema().params (the duplication is debt #36).
- C19: added a "Realization (cycle 0016 — param-set injection)" note (the per-cycle
  pattern C8/C10 already carry for 0005/0006/0007/0015): the value-empty leaf,
  build-then-wire bootstrap_with_params/compile_with_params, the typed kind/arity
  errors, the bit-identical compilat, and the C22 blueprint-view bare-type label
  (value-bearing SMA(2) now only in the compiled view).

debt (filed, carry-on):
- Every param-bearing node declares its ParamSpecs twice (factory() and schema()),
  kept in lockstep only by a per-node test; drift compiles. Filed as #36 (sibling of
  #34's traversal-duplication concern). Not active drift — the agreement holds and
  is tested per node.

regression: profile declares no regression scripts and no architect_sweeps — the
architect review is the sole gate. No baseline to update.

Cycle B is drift-clean after these amendments. NOT a milestone close — that needs
the end-to-end milestone fieldtest, deferred until the sweep root (#32-#33) lands.

Brummel 4b64409036 feat(aura-core,aura-std,aura-engine,aura-cli): inject a param-set vector at bootstrap (#31)
Cycle B of milestone "The World — parameter-space & sweep". A blueprint is now
value-empty: a leaf holds a param-generic recipe, not a built node, and a positional
Scalar vector is bound slot-by-slot at bootstrap — so one blueprint bootstraps into
many distinct instances under different vectors, with no cdylib rebuild (C12/C19).
This is the binding primitive a sweep (#32) drives.

Ratified design (brainstorm): value-empty reconstruct-through-new() over
mutate-in-place and over a default-bearing variant. The value lives only in the
injected vector (no baked default), keeping the blueprint a pure param-generic
recipe (C19); every injected value flows through the node's own constructor (the
single sizing/validation gate).

- aura-core: LeafFactory { name, params, build } — the recipe (params -> sized node
  through `new`); Scalar::as_i64/as_f64 value accessors. Node trait unchanged.
- aura-std: each of the 7 nodes exposes factory() (SMA length:I64, Exposure
  scale:F64, LinComb arity x weights[i]:F64; Sub/Add/SimBroker/Recorder paramless,
  capturing their non-param construction args — pip_size, the Recorder channel).
- aura-engine: BlueprintNode::Leaf(LeafFactory), From<LeafFactory>; param_space()
  reads factory.params() pre-build; compile_with_params/bootstrap_with_params build
  each leaf from its kind-checked slice while lowering (build-then-wire), arity
  checked up front via param_space().len(); CompileError::{ParamKindMismatch,
  ParamArity}. compile/inline/edge-rewrite are structurally unchanged, so the
  compilat stays bit-identical for a given point (the bit-identity and both
  param_space mirror tests stay green). The vestigial pre-build Composite::schema /
  BlueprintNode::schema (no live caller — interface resolution is structural on the
  built flat nodes) are removed.
- aura-cli: the blueprint view labels leaves by bare type via LeafFactory::label()
  (`[SMA]`) — the ascii-dag renderer cannot render wide cluster-sibling labels (see
  spec); the compiled view still labels valued (`SMA(2)`). The sample supplies its
  point as a vector; the mis-wiring swap moved to the compiled view.

The #34 dual-traversal drift hazard is subsumed: compile_with_params consumes the
vector in the same recipe walk param_space() reports, so the two share one
traversal.

Verified: cargo build/test --workspace green (127 tests, incl. bit-identity, both
mirror tests, and 4 new injection tests — different-vector-different-run, kind
mismatch, arity, determinism); clippy --workspace --all-targets -D warnings clean;
`aura graph` blueprint view renders cleanly.

Scope: one vector -> one instance. Deferred: sweep enumeration (#32), domain
validation (#32/C20), single-run authoring convenience (#35).

Brummel b02f31cdd4 spec: 0016 — blueprint-view label is the bare type (ascii-dag wide-label limit) (#31)
The amend chose `SMA(length)` (type + knob names) for the param-generic blueprint
view. Implementation surfaced that the ascii-dag 0.9.1 renderer writes a label
verbatim on one line (no multi-line — `render/ascii.rs::write_node` brackets the
raw string) and its Sugiyama subgraph layout overlaps two wide sibling boxes inside
a cluster (`[SMA(length[SMA(length)]`). Width is auto-computed but the cluster
packing does not honor it; the only spacing knob (`node_spacing`) is on the
deprecated config path, global, and width-independent — no robust option, and
domain labels grow unboundedly wide (`LinComb(weights[0], weights[1])`, deep
path-qualified names). Horizontal mode is already rejected (collapses fan-outs).

So `LeafFactory::label()` renders the bare node type (`SMA`). The tunable knobs are
surfaced by `param_space()`, not in the graph; the compiled view still labels built
nodes valued (`SMA(2)`) via `Node::label`. Correct C22 reading either way —
structure (now: type-only) before, values after.

Brummel bf5ff22371 plan: 0016 param-set injection (#31)
Four crate-gated tasks for spec 0016: aura-core (LeafFactory + Scalar accessors),
aura-std (factory() on the 7 nodes), aura-engine (value-empty Leaf, build-then-wire
compile_with_params/bootstrap_with_params, kind+arity errors, vestigial schema
removal, fixtures + injection tests re-expressed), aura-cli (param-generic render,
sample + goldens, swap moved to the compiled view). Compile gates are crate-scoped
so each task's gate is satisfiable with all its callers threaded in-task.

Brummel e9eea1ada3 spec: 0016 amend — value-empty render surface + vestigial schema removal (#31)
Plan-recon surfaced two surfaces the first draft under-scoped; resolved here after
a user design decision on the render form.

- Blueprint rendering (C22): a value-empty blueprint has no bound values, so the
  `aura graph` blueprint view can no longer label a leaf `SMA(2)`. LeafFactory gains
  `name` + `label()`, and the blueprint view renders the param-generic form
  `SMA(length)` (type + tunable knob names, no values), chosen over a bare `SMA` to
  surface the knobs the milestone is about. The compiled view (post-build flat
  nodes) is unchanged — it still labels valued. Correct C22 reading: structure
  before, values after.
- Vestigial pre-build interface removed: `Composite::schema` / `BlueprintNode::schema`
  derive an item interface from built interior leaves; a value-empty leaf has none,
  and both methods have no live caller (compile resolves every interface structurally
  on the built flat nodes). Removed with their unit test. This is why the factory
  carries no io skeleton — the build-then-wire decision stands, no schema duplication.
- OQ3: the swapped-sample mis-wiring moves from the builder args to the injected
  vector; its observability moves to the compiled view (the blueprint view is
  param-generic and identical for both orderings).

Grounding-check re-run: PASS (LeafFactory::label internally consistent; the
no-live-caller claim for the removed methods verified; blueprint-view vs
compiled-view goldens correctly partitioned).

Brummel b9edeaf2db spec: 0016 param-set injection — value-empty blueprints bound by a vector (#31)
Cycle B of milestone "The World — parameter-space & sweep". A blueprint's tunable
values are injected at bootstrap rather than baked into the builder: a leaf becomes
a param-generic recipe (LeafFactory: params -> sized node), and a new build-then-
wire compile path binds a positional Scalar vector slot-by-slot against
param_space(), building each node through its own constructor.

Ratified design (brainstorm): value-empty B over mutate-in-place and over the
default-bearing variant. The value lives only in the injected vector (no baked
default), so the blueprint stays a pure param-generic recipe (C19); injected
values flow through the single new() sizing/validation gate; and because
compile_with_params consumes the vector in the same depth-first order param_space()
reports, the two share one traversal — subsuming #34's dual-traversal drift hazard.

Scope: one vector -> one instance; LeafFactory in aura-core; bootstrap_with_params/
compile_with_params; CompileError::{ParamKindMismatch, ParamArity}; Scalar::as_i64/
as_f64 accessors; fixtures/CLI/bit-identity re-expressed against the vector.
Deferred: sweep enumeration (#32), domain validation (#32/C20), single-run
authoring convenience (#35).

Gates: grounding-check PASS (8 current-behaviour assumptions ratified against green
tests; the sole BLOCK — a missing Scalar value accessor — resolved by adding it as
in-scope surface). Parse gate a no-op (profile declares no spec_validation).

Brummel a31d91453c test(aura-engine): mirror param_space against compile() under nesting (#34)
The cycle-0015 E2E guard param_space_mirrors_compiled_flat_node_param_order
pins the load-bearing C23/#31 invariant — Blueprint::param_space() slot order
mirrors compile()'s flat-node param order kind-by-slot — but only on the
single-level composite_sma_cross_harness. collect_params (blueprint.rs:217)
duplicates lower_items' depth-first traversal rather than sharing it (kept a
parallel read-only projection so compile/inline_composite stay untouched and
the compilat bit-identical, C9/C23), so the two orders must stay in lockstep
forever. No mirror test ever compiled a composite-inside-a-composite: a future
inliner reorder that desynced the projections only under nesting could pass the
single-level mirror and the isolated nested param_space order test, yet break
the slot-by-slot premise #31's binding rests on.

Adds param_space_mirrors_compiled_flat_node_param_order_under_nesting: compiles
a strategy -> { fast_slow -> [Sma, Sma, Sub], LinComb } nest and asserts
param_space() equals the compiled flat-node param order kind-by-slot, pinning
the concrete [I64, I64, F64, F64] shape. Green immediately — coverage-hardening,
no desync in the current tree. Test-only; collect_params/lower_items/compile
untouched.

Verified: cargo test -p aura-engine green (55 tests), clippy --all-targets -D
warnings clean.

Brummel 2a9a141a6f audit: cycle A (0015) — ledger amendments (C8/C23), debt #34 filed
Architect drift review of the #30 cycle (561482c..931109d) against the design
ledger. Code holds: param_space() is a read-only C9 projection, compile/inline
untouched, compilat bit-identical, positional identity (C23) and topology-fixed
vector arity (C19) implemented and well-covered. Two ledger drifts + one debt item.

ledger (fixed here):
- C23 'Status' parenthetical said the sweep pass 'presupposes per-node param
  declarations (C8 — deliberately not in the schema yet)' — now stale, the
  declarations landed this cycle. Reworded to 'landed in cycle 0015 as name+kind;
  swept range still pending #32/C20'.
- C8 guarantee promises params 'typed, with ranges' but cycle 0015 shipped name+
  kind only. Added a 'Realization (cycle 0015)' note (the established per-cycle
  pattern, as C8 already carries for 0005/0006) recording what landed and the
  load-bearing refinement from the design discussion: the SEARCH-RANGE is the run's,
  not the node's (#32/C20) — the node declares the knob's existence and type, never
  its search interval; identity is positional (slot), the path-qualified name a
  non-load-bearing debug symbol.

debt (filed, carry-on):
- collect_params (blueprint.rs:217) duplicates lower_items' traversal order rather
  than sharing it (deliberate — keeps param_space a parallel projection so the
  compilat stays bit-identical). The E2E mirror guard is shape-specific (no nested-
  composite compile case). Filed as #34 to harden before #31 binds atop the
  invariant. Not active drift — the guard exists, only the shape coverage is partial.

regression: profile declares no regression scripts and no architect_sweeps — the
architect review is the sole gate. No baseline to update.

Cycle A is drift-clean after these amendments. NOT a milestone close — that needs
the end-to-end milestone fieldtest, deferred until the sweep root (#31-#33) lands.

Brummel 931109df58 feat(aura-core,aura-std,aura-engine): declare node tunable params (#30)
Cycle A of milestone 'The World — parameter-space & sweep'. A node now declares
its tunable parameters in its C8 schema, and a blueprint aggregates them into one
flat, inspectable param-space — the root that unlocks the C12 orchestration axes
(#31 bind, #32 sweep), filling the gap C8/C23 name 'deliberately not in the schema
yet'.

- aura-core: ParamSpec { name: String, kind: ScalarKind } as a third schema-
  declaration type; NodeSchema gains a third field 'params'. name is String (not
  &'static like FieldSpec) because a vector knob carries a runtime index and
  aggregation prefixes the composite path.
- aura-std: Sma declares [length:I64], Exposure [scale:F64], LinComb expands to N
  flat [weights[i]:F64] (N = its input arity, topology-fixed per C19); Sub/Add/
  SimBroker/Recorder declare none (pip_size is metadata, C10/C15; Recorder is
  wiring).
- aura-engine: Blueprint::param_space() walks the graph-as-data depth-first in
  lower_items order, path-qualifying via the already-public Composite::name() — a
  read-only projection (C9). compile/inline_composite/lower_items are untouched, so
  the compilat stays bit-identical (composite_sma_cross_runs_bit_identical_to_hand_wired
  and the golden render tests stay green).

Design: param identity is positional (slot after the deterministic inline order,
C23 'by index not name'); the path-qualified name is a non-load-bearing debug
symbol — same-type siblings in one composite share a name, uniqueness is at the
slot. Flat over a structured arity-bearing ParamSpec because flattening is
unavoidable (a sweep enumerates a flat point-space) and structure-in-the-runtime
is the nested-composite reading C23 rejects (see spec 0015 for the full rationale).

Scope is declaration + aggregation + inspection only; binding (#31), sweep
enumeration (#32), search-range, validity-constraint, and default-range/slider are
deferred. An E2E test pins the load-bearing C23/#31 invariant: param_space() slot
order mirrors compile()'s flat-node param order, kind-by-slot, on the SMA-cross
harness. fieldtests/ (excluded crates) left as frozen snapshots.

Verified: cargo build/test --workspace green (64 tests), clippy --all-targets -D
warnings clean; compile/inline diff empty.
