audit: cycle metric-vocabulary tidy — ledger records the retired #147 deferral
Cycle-close audit (architect: drift_found, design core clean). What holds, architect-confirmed: C18 bit-identity for RunMetrics (prose derived byte-identically, rng order preserved, registry suite unchanged); the C10 wall (monomorphic R-gates, r_based in the R vocabulary, cross-vocabulary refusal tested both ways — no leak); C28 direction (trait in aura-analysis, vocabulary supplied from the outer rungs, zero Cargo edge changes); C1 determinism pinned through the generic path. Drift items, all resolved as fixes in this commit: - design ledger: the C28 #147 disposition now records item 2 SHIPPED (the A1 cut) with A2 still deliberately deferred; the #136 one-implementor clause carries a supersession note (the IC is the second implementor). - seven stale doc comments describing the pre-#147 or mid-cycle state (analysis trait + estimator docs, registry check_r_metric C9 claim, engine re-export note, campaign PER_MEMBER_METRICS roster note, member-seam guard comment, research vocabulary note) updated to the shipped state. - R_BASED_METRICS is now oracle-pinned against RunMetricKey::r_based() in the vocabulary test (it feeds the NonRMetric refusal prose; a divergence would have misreported the R-gate silently). Noted, not amended (history stays): commit 6744f67's body says 'three syntax-only edits' where the test module actually took five. No regression scripts are configured (the bench is report-only); the architect review is the gate. Verification: extended vocabulary test, campaign suites, analysis/research suites green; clippy --workspace -D warnings clean. refs #147 |

refactor: registry deflation dispatch generic over the MetricVocabulary trait
The A1 cut of #147 item 2, part 1 of 2 (the substrate): the registry's ranking/deflation machinery no longer bakes in the R metric vocabulary. - aura-analysis gains the deliberately narrow MetricVocabulary trait (name resolution, roster, direction, value read, one null draw) and the single-sourced one_sided_p_laplace estimator; re-exported through aura-engine's existing seam (no Cargo.toml edge changes anywhere). - aura-backtest now OWNS the R vocabulary: RunMetricKey (was the registry's private Metric enum, exposure_sign_flips alias preserved), r_based (the C10 classification), R_BASED_METRICS/RANKABLE_METRICS rosters, the centred moving-block null_draw, and member_metric_from_rs. - aura-registry: metric_cmp/rank_by/null_best_of_k/member_sd generic over M: MetricVocabulary; optimize/optimize_plateau/optimize_deflated over M: MetricVocabulary + Clone (SweepPoint<M>: Clone bounds on M: Clone); the private vocabulary deleted; check_r_metric/generalization stay monomorphic on the RunMetrics vocabulary (the C10 wall by type); RegistryError::UnknownMetric carries the vocabulary's roster so the refusal prose derives instead of being hand-strung (byte-identical for R). Bit-identity (C18): rng consumption order, centring, Laplace arithmetic, floors, tie rules, and refusal prose are all unchanged for RunMetrics inputs — the full registry suite (75 tests) passes unchanged except three syntax-only edits for the UnknownMetric variant reshape; clippy -D warnings clean on the three touched crates. Alternatives considered: a vocabulary table in aura-core (rejected: inverts C28's supplied-from-outer-rungs direction and cannot host the null model); a parallel measurement-side deflation path (rejected: duplicates the machinery and adds a fifth roster). Part 2 lands the consumers (campaign roster single-sourcing, the IC implementor, acceptance tests). refs #147 |

refactor: cut the engine's backtest-metrics edge via RunReport<M>
C28 phase 2 (Stratification); realizes item 1 of the deferred #147. The engine's production surface no longer names a backtest-metric type: - RunReport becomes generic over its metric payload M; sweep/mc/walkforward/ blueprint thread the parameter (SweepPoint<M>, SweepFamily<M>, WindowRun<M>, WalkForwardResult<M>). RunManifest stays concrete and engine-owned (its selection: Option<FamilySelection> embeds the foundation-grade analysis type). - summarize and the MC assembly (McDraw/McFamily/McAggregate/RBootstrap/ r_bootstrap/monte_carlo) move to aura-backtest - McAggregate::from_draws reads RunMetrics fields by name, so generifying it is the phase-6 metric-vocabulary abstraction (#147 item 2), still deferred; wholesale relocation is the honest cut. The concrete instantiation lives in aura-backtest as `type RunReport = aura_engine::RunReport<RunMetrics>` + sibling aliases. - the statistics kernel (MetricStats/quantile/resample_block/SplitMix64) moves to the aura-analysis foundation; the engine re-imports it (inner->foundation, legal) and re-exports it so existing consumers stay source-compatible. Dependency inversion in one commit: aura-engine drops aura-backtest from [dependencies] (back to dev-deps for its SimBroker/RunMetrics test fixtures); aura-backtest gains aura-engine. Cycle-free for lib targets - the cycle closes only through the engine's dev-dep edge, the pattern aura-vocabulary already uses. aura-backtest reaches the kernel transitively through the engine re-export, so no aura-backtest -> aura-analysis edge exists (the C28 ladder permits backtest -> {core, engine} only). run_indexed / SplitMix64::next_f64 widened pub(crate) -> pub for cross-crate use. Consumers (registry/campaign/cli/composites/ingest/bench) rewired by import path only, no call-site logic changed. The c28_layering structural test extends to the full ladder: aura-analysis (no aura-* deps), aura-engine ⊆ {core, analysis}, aura-backtest ⊆ {core, engine}. Behaviour-preserving: 1448/0 tests, clippy -D warnings clean, serde shapes byte-identical (C18 - RunReport<M> keeps field order manifest,metrics; the CLI pre-serialized-splice contract unchanged), moved code traceable via git rename detection. Cycle-introduced broken intra-doc links fixed. closes #292 |

refactor: split aura-analysis into statistics and backtest metrics
C28 phase 5 (Stratification): the backtest reductions - RunMetrics, RMetrics, summarize_r, r_metrics_from_rs, and the position-event table - move verbatim into aura-backtest::metrics, beside the position_management producer whose record layout they read (the r_col/cost_col lockstep contract is now intra-crate; its stale "aura-std" comment corrected). aura-analysis is reduced to the domain-free half: the multiple-comparison hurdle math (inv_norm_cdf, expected_max_of_normals) and the selection-provenance types (FamilySelection/SelectionMode - kept beside the statistics so RunManifest.selection embeds a foundation-grade type), [dependencies] = serde only. The engine re-export surface is name-unchanged (report.rs re-imports from both crates), so no indirect consumer needed a source edit; aura-backtest moves from aura-engine's dev-dependencies into [dependencies] as a commented TRANSIENT widening of the C28 violation, removed by the phase-2 edge cut on this branch. The campaign drift guard imports its pinned types from their new source crates. Behaviour-preserving: 1448/0 tests, clippy -D warnings clean, serde shapes byte-identical (C18), moved code traceable via git copy detection. closes #291 |

refactor: split the aura-std roster into C28 layer crates
Phase 4 of the Stratification milestone. aura-std held four C28 ladder layers in one roster; this cuts them into layer-aligned, aura-core-only node crates so the import direction is enforced by the crate graph: - aura-std — engine nodes only (arithmetic/logic/rolling + sinks) - aura-market — session, resample - aura-strategy — bias, stops, sizer, cost-model machinery - aura-backtest — sim_broker, position_management - aura-vocabulary — the relocated closed std_vocabulary roster Node modules move verbatim (byte-identical renames); consumers are rewired by import path only. A new structural test (aura-vocabulary/tests/c28_layering.rs) asserts each node crate's [dependencies] stay within its C28-permitted inner set, catching the acyclic-but-outward violation the compiler misses. Behaviour byte-identical: full workspace suite green (1448 tests), no golden edited, clippy -D warnings clean. C28 Status block updated. closes #288 |

feat: measurement run verb — shape-dispatch aura run on blueprint output
Phase 3 of the Stratification milestone (contract C28). `aura run` now
shape-dispatches on the loaded blueprint: a `bias` output takes the
existing strategy path (wrap_r + R evaluation), byte-identical; a
blueprint that declares taps but exposes no `bias` runs bare via the new
`run_measurement` (bootstrap, run, drain the declared taps) with no
SimBroker, no risk executor, and no per-cycle equity/exposure/r
recorders; a blueprint exposing neither is refused. This gives the
measurement layer its own run verb and removes the O(cycles) recording
retention (the measured ~2 GB peak RSS over 12y UK100 M1) the mandatory
R scaffold imposed on a measurement-shaped run.
A new `MeasurementReport { manifest, taps }` (aura-engine::report, beside
RunReport) is the stdout/record shape — no R metrics, since a bare run
has no broker. The manifest's `broker` carries an interim "measurement"
sentinel; the honest `Option<String>` model is deferred to the #147
metric-genericity block, keeping this phase #147-free and the
strategy-path C18 goldens byte-identical.
`run_signal_r` is untouched (the tap machinery is duplicated into
`run_measurement`, not extracted). The measurement arm's closed-blueprint
guard uses `signal.param_space()` rather than `blueprint_axis_probe`,
which welds wrap_r and would panic on a no-`bias` signal.

audit: close #284/#285 cycle — GraphBuilder::tap twin restores C24 symmetry
Cycle-close tidy for the #284 (tap construction op) + #285 (docs) cycle. The architect drift review (cb6211c..HEAD) came back drift-clean on the ledger contracts the cycle touched — C27 machinery untouched, a faithful `expose` twin (C25 preserved), lockstep op<->OpDoc / OpError<->format_op_error arms paired, and the #285 docs verified accurate against aura-std/src/session.rs — save one drift item, fixed here. Drift item (fixed): the op-script gained `Op::Tap` but `GraphBuilder` had no `tap()` twin, softening C24 (replay-equals-builder = one construction semantics) and C17 (builder-primacy) — every other op verb has a builder twin. Unlike the op-script's `doc` gap (a ledger-recorded #125 scope cut), this asymmetry had no rationale; a tap is a first-class authoring act on both surfaces, so denying only the fluent builder was an accident of incremental delivery, not a design cut. Fix: `GraphBuilder::tap` (builder.rs), the exact output-side mirror of `expose` — a `taps: Vec<(String, OutPort)>` accumulator resolved at `build()` into `Tap { name, from: TapWire }` and threaded via `.with_taps`. Plus a construction.rs lockstep test `tap_replay_matches_builder` proving the op-script `Op::Tap` replay and the `GraphBuilder::tap` twin serialize to byte-identical blueprint JSON and compile to identical `FlatGraph.taps` — the tap op is the by-identifier face of the same construction semantics, not a second one. Carry-on (architect debt-low, no action): commit 43a1cc4's body phrase "op-built composites silently lost their taps" over-claims a prior drop (no tap op existed pre-cycle); the "latent" qualifier keeps it honest, so the wording is left as-is rather than rewriting an already-landed commit. Verification: full `cargo test --workspace` green; `cargo clippy --workspace --all-targets -- -D warnings` clean. The bench is report-only by project convention and was not run — this cycle adds a construction-time op + docs, no hot-path change. Fieldtest: the #284 `tap` surface is exercised from the public interface by two E2E consumer-path tests (op-script -> `aura graph build` -> `aura run` -> persisted trace) plus two worked authoring examples hand-verified through the built binary; #285 is documentation. The per-cycle fieldtest is satisfied. Spec + plan working files (docs/specs/tap-construction-op.md, docs/plans/tap-construction-op.md) discarded per audit Step 5 (git-ignored, never committed; their design intent lives in the commit bodies + the ledger). |

feat(graph): name-addressed tap construction op — declared taps without raw indices
Declared taps (C27, #282) were authorable only by hand-patching the raw blueprint envelope's `taps` array, where `node` is a raw interior index — an index miscount was the expected mistake and the root friction behind the two `aura run` panics the measurement-milestone fieldtest found. Add a `tap` op to the construction op-script vocabulary — the exact output-side twin of `expose`. It names its source wire by the dotted `"node.field"` identifier the op surface uses everywhere (`split_port` + `resolve_output_field` + `node_index`), so `{"op":"tap","from":"fast.value","as":"fast_ma"}` replaces patching `{"node":14,"field":0}`. Engine (construction.rs): `Op::Tap`, its `tap()` handler (a verbatim twin of `expose` — same resolvers, same name-dedup, appending a `Tap` to a new `taps`/`tap_names` namespace), and `OpError::DuplicateTap` (the twin of `DuplicateOutput`, stricter than the raw envelope, which enforces no tap-name uniqueness). `finish()` now threads `.with_taps(self.taps)` into the built `Composite` — fixing a latent drop #282 left (it built `.with_gangs` but never `.with_taps`, so op-built composites silently lost their taps). CLI (graph_construct.rs): `OpDoc::Tap` (externally tagged, `"as"`-renamed like `expose`) + the `kind_label` / `From` / `format_op_error` arms (the last compiler-enumerated by the exhaustive match). No change to the `Tap` / `FlatTap` / `bind_tap` / `aura run` machinery — the op-declared tap flows through the existing #282 compile + record path unchanged. Verification: 7 new tests green (4 engine: resolve+append, bad-port / ghost-node refusal, duplicate-name refusal, finish-threads-into-FlatGraph; 1 CLI serde round-trip; 2 CLI E2E over the real `aura graph build` / `aura run` subprocess — one pinning the exact serialized `"taps":[{"name":"fast_ma","from":{"node":0,"field":0}}]`, one proving an op-authored tap round-trips through build -> run -> persisted trace). Full workspace suite green; clippy clean. The RED-before-GREEN step was verified by a temporary stash of the production edits (the `Tap` / `with_taps` machinery pre-existed from #282, so a fresh RED-only test could not be authored) — the new tests fail without the edits, pass with them. Docs (the authoring-guide `tap` row, the ledger op-list `tap` line, and a worked tap-authoring example) are deliberately out of this commit's scope — they land in #285, the docs follow-up in this same cycle. closes #284 |

feat(engine): FlatGraph::bind_tap + TapBindError (#282)
The run-mode-aware bind seam. bind_tap attaches a CALLER-BUILT Box<dyn Node> sink to a declared tap — appending the sink node + an edge from the tap's (node, field) to its input, before bootstrap so the Kahn sort orders it. The engine constructs no aura-std type (it takes a Box<dyn Node>), keeping its production dependency aura-core-only. bind_tap raises UndeclaredTap; duplicate detection across binds is the caller's (the engine keeps no cross-call state), mirroring how bind_sources' DuplicateFeed is a supply-level fault. TapBindError is exported for the CLI. A bound tap records exactly the producer's per-cycle output through the full public pipeline; an undeclared name is refused without mutating the graph. refs #282 |

feat(engine): compile resolves and hoists declared taps (#282)
The compile core. resolve_tap_wire resolves a blueprint Tap's interior
{node, field} through the lowering table exactly as OutField re-exports and
edges resolve — a leaf to its remapped index (output-arity checked), a nested
composite through its output remap. Taps are terminal (not re-exported through
the boundary): a flat_taps accumulator threads through the lowering recursion,
so an interior composite's taps hoist to the root FlatGraph.taps with remapped
wires — the case the CLI single-run wrapper relies on. validate_wiring gains a
tap leg (threaded at all three call sites incl. GraphSession::finish) and
CompileError::TapWireOutOfRange names a bad wire. Root-resolve, out-of-arity,
and nested-hoist are pinned green.

feat(engine): FlatTap type + FlatGraph.taps field (#282)
Second slice: the resolved-tap carrier. FlatTap { name, node, field } is the
output-side twin of SourceSpec — its name survives compile, load-bearing for
by-name binding (#275). FlatGraph gains a taps field, threaded (empty) through
every construction site the compiler enumerates. Bootstrap ignores it (taps
materialize as real recorder nodes/edges before bootstrap in a later slice).
Purely additive: the inert-producer pin and full suite stay green.

feat(engine): Tap/TapWire declaration on the blueprint format (#282)
First slice of declared taps: a Tap { name, from: TapWire { node, field } }
is the output-side twin of input_roles — a pure data declaration naming an
interior output wire, no sink endpoint. Composite gains a taps field
(with_taps/taps(), additive) and the serde mirror CompositeData carries it
(Tier-1 additive: no format-version bump, absent-taps documents byte-stable).
Tap/TapWire are re-exported from the crate root beside Role/OutField so
downstream crates can author tap-bearing blueprints.

test(engine): pin that a no-out-edge producer runs inertly (#282 substrate)
Current-behaviour pin for the declared-taps design: a producer node with a non-empty output and zero out-edges compiles, bootstraps, and runs — its per-cycle output silently discarded — observably identical to the same graph with the producer removed. This is the exact shape of an unbound declared tap (a study wire left un-recorded in a sweep), and it establishes that the engine already tolerates it: no DCE is needed for correctness, because check_ports_connected gates only input slots and the Kahn sort emits a no-out-edge node as a valid sink. The build-time-elision soundness the tap mechanism will rely on. refs #282 |

test(engine): pin When's gated-reducer and barrier-stall semantics
Two integration pins for the clock-enable design (#281), at the raw FlatGraph boot seam. The gated-reducer equivalence is the crux claim: SMA(When(x, gate), N) equals SMA(N) fed the gate-true subsequence directly — When's quiet cycles do not advance the reducer's freshness, so its state moves per forwarded sample, not per cycle. The barrier stall pins that a quiet When member keeps its whole Barrier(0) group from firing that cycle. An in-graph AboveGate fixture derives the Bool gate co-fresh with the value leg. refs #281 |

feat(engine): shared rayon pool for the disjoint-parallel core
Replace the per-call std::thread::scope fan-out in run_indexed with one process-wide rayon pool. run_indexed's callers nest — sweep (grid points), monte_carlo (seeds), and walk_forward (window bounds), where a walk_forward window runs an inner sweep — and each std::thread::scope spawned its own available_parallelism() OS-thread batch, so the two levels multiplied to ~available_parallelism()^2 threads (measured 150-240 concurrent on a 24-core box during a 42-cell campaign, ~10x oversubscription). rayon's pool is process-wide and persistent: a nested par_iter work-steals within the same N workers instead of spawning, so live workers never exceed the pool size. Determinism (C1) is preserved bit-for-bit: run_indexed collects via IndexedParallelIterator in enumeration order (not completion order), and the float aggregation (summarize_r / McAggregate / stitch) runs after the ordered collect, so IEEE-754 non-associativity introduces no variance. The existing _with_threads(1) == _with_threads(8) == public determinism tests stay green, now driving local rayon pools of 1 and N workers via ThreadPool::install. Structural inversion: the public sweep/monte_carlo/walk_forward become the core (calling run_indexed on the ambient pool through a shared assemble_* helper); the _with_threads variants collapse into thin, test-only wrappers (#[cfg(test)]) that run the same assembly inside a local pool. run_one stays Fn + Sync (no + Send): run_indexed borrows it in the map closure and the wrappers borrow it into install — passing it by value would move it into rayon's Map and force F: Send, a bound the public callers do not carry (hence the load-bearing #[allow(clippy::redundant_closure)] on run_indexed). Adds a nested-oversubscription regression test (asserts nested run_indexed never exceeds the pool size — the pre-rayon shape ran POOL^2) and an ignored wall-time benchmark. rayon admitted under the amended-C16 per-case dependency policy; it stays within C1 (parallelism across sims, never within one). This is the shared pool only — the first of three steps toward saturating the cores. The diagnosis found the larger loss is the idle valleys (~42% of the box idle: the sequential cell loop and the single-threaded bootstrap), which the pool alone does not fill. Two follow-ups are filed and recorded on #268: the Registry write path is not concurrency-safe (append_family races on a shared families.jsonl), the prerequisite for parallelizing the C1-disjoint cell loop with a RAM budget bounding concurrently-active instruments (the FileCache retains a symbol's parsed files while any reference is live). Verified: cargo test -p aura-engine (276 passed, the C1 determinism tests green), the new oversubscription test green, the benchmark runs (no overflow), clippy -D warnings clean, cargo test --workspace no failures. closes #268 |

audit: cycle-close tidy for #275 (by-name source binding)
refs #275
Drift review (architect) over ad4249f..HEAD found the cycle drift-clean at the core
and confirmed what holds: C1 preserved (`run()`'s k-way merge / event loop has zero
diff — `run_bound` only reorders the supply via `bind_sources` then delegates to
`run`, byte-identity pinned); the C4 realization and C23 refinement ledger notes are
accurate and tightly scoped (`SourceSpec.role` is read in exactly one place, sourced
only from the lowering — no leak); and all three binding-carrying production run sites
moved to `run_bound` + `key_supply`, every remaining `.run(` being `#[cfg(test)]`. No
regression harness exists, so the architect is the sole drift gate.
One medium drift item fixed:
- FIX: the CLI's `.expect()` on `run_bound` covered Missing/Extra/Unnamed feed but not
`DuplicateFeed`. The blueprint path does not enforce root-role-name uniqueness (only
the construction op-script path does), so a duplicate-role blueprint would reach
`bind_sources`' `DuplicateFeed` and panic behind the `.expect()` instead of refusing.
Closed at the binding boundary: `resolve_binding` now refuses a duplicate input-role
name — a named `aura:`-register refusal on every CLI run path (single run, sweep, and
campaign all resolve the binding upfront), matching its existing price/close-ambiguity
refusal. The `.expect()` invariant is now genuinely true on all paths. Pinned by
`binding::duplicate_role_name_refuses`.
Two low items:
- `SourceBindError::Display` had no test (its renderer stays dead until a
decoupled-supply caller lands, #124). Added `source_bind_error_display_names_the_role`
pinning the message strings; reachability is deferred by design.
- The reverted fieldtest `SourceSpec` sweep leaves the corpus one more revival break
against the current engine API — carried, as the corpus is pre-existing bit-rot
unrelated to this cycle (documented in

feat(engine): bind ingestion sources by role key — SourceSpec.role + bind_sources/run_bound
refs #275 The engine-side half of by-name source binding. `SourceSpec` carries a load-bearing `role: Option<String>` — `Some(name)` for a spec lowered from a bound `Role` (carried through the blueprint lowering, previously dropped at compile), `None` for a hand-built raw-index spec. A pure `bind_sources(specs, keyed_supply)` resolves a `Vec<(role, Box<dyn Source>)>` into the positional `Vec` `run` consumes, in `SourceSpec` declaration order, erroring named (`SourceBindError`: Missing/Extra/Duplicate/Unnamed feed) on a mis-bind. `Harness::run_bound` is the ergonomic method the by-name production path calls. The raw-index `run(Vec)` primitive and the k-way merge / per-cycle event loop are untouched: a positional run stays byte-identical (C1, pinned by `run_bound_out_of_order_matches_positional_run`), and every existing `run(Vec)` caller keeps working (it ignores `role`). A `BTreeMap` index makes the Duplicate/Extra diagnostics deterministic. C4's tie-break guarantee ("source declaration order") is unchanged — `bind_sources` emits in `SourceSpec` order, so the merge's source-index tie-break resolves on declaration order regardless of the caller's supply order. The narrow C23 amendment (a `SourceSpec.role` is load-bearing for source binding, the rest of the flat graph stays raw-index) is deferred to the ledger note. The four error-path RED tests assert via `.map(|_| ()).unwrap_err()`: the `Ok` arm `Vec<Box<dyn Source>>` is not `Debug` (`Source` has no `Debug` supertrait), so a bare `.unwrap_err()` would not compile — a plan-byte defect corrected here. Also sweeps the 45 raw-index `SourceSpec { .. }` literals to `SourceSpec::raw(..)` across the workspace (mechanical, compiler-enumerated) and pins that a bound root role's name survives lowering. Verification: `cargo test --workspace` green (0 failed; incl. 5 `bind_sources` cases, the `run_bound` byte-identity test, the role-survives-lowering pin, and the four `.sources`-equality twins under the now-stricter `role` equality); `cargo build --workspace --all-targets` clean; `cargo clippy -p aura-engine --all-targets` clean. |

feat(engine,cli): run manifests stamp untouched bound defaults (closes #249)
RunManifest gains defaults: Vec<(String, Scalar)> — the wrap-prefixed bound_param_space() of the signal, read after axis reopening, so a bound param an axis overrode has already left the space and flows through params instead (disjoint by construction; verified end to end: a sweep member's overridden fast.length sits in params while slow.length/bias.scale sit in defaults). params keeps its "what varied" semantics and stays the reproduce input. One-directional serde widening (#[serde(default)]) per the selection/instrument/topology_hash idiom — old records deserialize with an empty defaults; unlike the Option fields it always serializes, mirroring params. ~20 struct-literal sites across five crates gained the field (compile-mandated breadth, no behaviour change at those sites). The C14 ledger records the underlying decision (2026-07-13): generated outcome records spend redundancy on direct readability (single writer, cannot drift); authored intent artifacts admit none (every redundancy is a drift site) — so the fix lands in the manifest, never the blueprint. Verification: RED test run_manifest_stamps_untouched_bound_defaults green; cargo build --workspace; cargo test --workspace green; clippy -D warnings on the touched crates; binary-level sweep exclusivity check. |

feat(core,engine): bound params become data-merged defaults; Composite::reopen
Task 1-2 of the bound-override cycle: PrimitiveBuilder::bind/try_bind stop capturing the bound value in a wrapped build closure and store it only as BoundParam data; build() merges bound values back into the full-arity vector at call time (ascending original position — behaviour-identical to the retired closure chain). This makes the reversal possible: unbind(slot) returns the param to the declared surface at its original order. aura-engine gains the path-addressed Composite::reopen (mirroring collect_params' prefix rules, lockstep with expansion_map) plus the read-only bound_param_space() enumeration (path-qualified BoundSpec with values) and the ReopenError/BoundSpec exports. An e2e proves a reopened param rebuilds from the freshly supplied value through compile_with_params, not the stale default. refs #246 |

The tail audit over d1e01ef..62f6592 found no code drift against the contracts (C18 name-resolution read-only, C23 doc identity-blind and inline-dissolved, C1 fit deterministic) but four lagging records, fixed here: the #106 real-roller amendment gains the #239 fit-to-window note (fixed sizes are a ceiling on the sugar path); a #125 realization note records the composite doc as a C23 debug symbol with its serde/identity/ viewer treatment; the glossary identity-id and composite entries name the doc; GraphSession::finish states the deliberate absence of a doc-carrying op-script surface (refs #125) instead of leaving the authoring asymmetry silent. |

feat(engine): composite doc field — authoring, serde, identity, model emit (refs #125)
Composite gains doc: Option<String> (the prose twin of name, a C23 debug symbol): with_doc/doc() on Composite, a doc knob on GraphBuilder, a Tier-1 additive-optional CompositeData field (no format-version bump; absent-field documents keep their exact bytes), identity-stripped like the name. The graph model emits an optional trailing doc fragment in both scopes; json_str is hardened for free text (\n/\t/\r named, control chars as \u00XX — the doc is the first multi-line value through it). e2e: a hand-authored doc'd blueprint renders with the doc embedded; the doc moves the content id but never the identity id. refs #125 |

audit: param-gang cycle close — drift-clean, mirror-walk interleave pinned
Architect review over 962b249..fc9cf23: clean. What holds: check_gangs is the single structural predicate at all three minting boundaries (builder.rs:226, construction.rs:396, blueprint_serde.rs:222 — the eager op arm is the sanctioned by-identifier subset, connect/edge_kind_check precedent); identity stays debug-name-blind per #171 (gang/member names blanked, (node,pos,kind) survives); format version 1 + Tier-2 dormancy note consistent across code and C24 ledger; no stale two-axis / 'separate #61' claims survive in docs or comments; commit-body deviation claims verified true against the diff. The one [low] finding — the new collect_params<->expansion_map mirror-walk lockstep pair untested for gang members interleaved with other open params — is closed here (fix disposition) with ganged_interleave_shift_through_matches_member_bound_twin: LinComb.weights[1] ganged with Bias.scale while weights[0] stays open earlier on the SAME node and Sma.length follows the gang in walk order; equality asserted on param_space order, wiring, and full run traces vs the member-bound twin. Load-bearingness proven by an injected double-count bug failing the test. Verified: aura-engine lib 265/0, clippy -D warnings clean. refs #61 |

feat(engine,cli): GraphBuilder gang cadence + render carrier (#61 tasks 5-6)
Builder: NodeHandle::param -> ParamRef, GraphBuilder::gang, build() resolves
the gang table (collect-then-reject, BuildError::{UnknownParam,AmbiguousParam,
BadGang}) and terminates in Composite::with_gangs — the same predicate the
op-script and serde boundaries use. C24 lockstep extended: an op-script gang
replay serializes byte-identically to the GraphBuilder twin (FlatGraph edges +
sources + canonical JSON).
Render: model_to_json emits a per-scope gangs fragment (name, kind, [node,pos,
"param"] members) for ganged scopes only — the gang-free model stays
byte-identical (model_golden untouched). graph-viewer.js annotates a ganged
open param with its public knob name; guarded by a viewer_gang_param.{mjs,rs}
pair RED-first per the established viewer_bound_param convention (a welcome
extra beyond the plan's file list).
Ratified deviation: the model's kind string uses the serde form ("I64") — the
plan's implementation snippet (kind_str -> "i64") contradicted its own test;
resolved toward the test + the blueprint_serde form. Two quality nits held as
principled plan-holds (inline resolution block; the unreachable unwrap_or
placeholder check_gangs refuses first).
Verified: aura-engine lib 264/0 (model_golden, lockstep, builder, carrier all
green), viewer_gang_param 1/0, workspace clippy -D warnings clean. Slice
resumed across a transient API failure via workflow resume (cached prefix).

feat(engine,cli): gang serde + identity + the gang construction op (#61 tasks 3-4)
Serde: CompositeData carries an additive-optional gangs section (omitted when empty — every existing v1 document round-trips byte-identically, NO format-version bump per the #61 decision; BLUEPRINT_FORMAT_VERSION doc now records the pre-ship Tier-2 dormancy). project() emits gangs canonically (members by (node,pos), gangs by first member) so declaration order never reaches the content id; reconstruct() re-mints through Composite::with_gangs and a corrupted section refuses as the new typed LoadError::Gang. strip_debug_symbols blanks gang + member names, keeps (node,pos,kind) — the identity id stays gang-name-blind and gang-structure-sensitive. Construction: Op::Gang { as_name, into } with the feed-style two-phase eager arm (member resolution against the post-bind schemas, kind uniformity, single-gang membership; OpError::{GangKindMismatch,AlreadyGanged,GangArity}); finish() routes the assembled composite through with_gangs, and gang-name collisions surface via the existing injectivity gate on the projected space. CLI: OpDoc::Gang ({"op":"gang","as":…,"into":[…]}), kind_label/From/ format_op_error arms, and format_load_error phrases gang faults as prose (gang_fault_prose) instead of leaking Debug — a ratified improvement over the plan bytes. Held quality nit (principled plan-hold): gang()'s inline collect-then-reject param resolution is the module's established convention (bind/try_bind); a shared cross-crate helper is out of this task's scope. Verified: workspace build clean, aura-engine lib 258/0, aura-cli graph_construct 48/0 (incl. the new gang-op e2e), clippy -D warnings clean. refs #61 |

feat(engine): gang param-space projection + compile-front point expansion (#61 task 2)
param_space()/derive_signature project each frame's gang table: member addresses are skipped, the gang's single public address (prefixed like any knob at that frame) is emitted once at its FIRST member's raw position — so every consumer of param_space (binders, grids, campaign axes, --list-axes, registry coverage) inherits the gang with zero changes. compile_with_cells expands the public point back onto the raw layout via expansion_map (the collect_params mirror walk): a gang's cell is duplicated into every member slot, un-ganged slots pass through. For a gang-free blueprint the map is the identity and behaviour is byte-identical; the lower_items cursor walk and all build closures are untouched. The load-bearing equivalence is pinned in-module (ganged compile == the member-bound un-ganged twin, bit-identical wiring and run output) and again from OUTSIDE the crate in tests/gang_e2e.rs — the C24 consumer seam a project crate or the World actually uses. Verified: cargo test -p aura-engine 253/0 lib + 5/0 gang_e2e (all groups green), workspace clippy -D warnings clean. RED-first evidenced by the loop via temporary call-site reversion (all 4 new tests failed for the expected reason, then the implementation was restored). refs #61 |

feat(engine): gang data model + validation gate (#61 task 1)
One public knob fanning into >=2 sibling params: Gang/GangMember types
(the Role name/targets split + BoundParam pos/name dual), Composite.gangs
behind the single fallible Composite::with_gangs gate, check_gangs as the
shared $A predicate (all three future minting boundaries route here), and
CompileError::BadGang(GangFault) as the typed refusal.
PrimitiveBuilder::original_pos (aura-core) extracts bind's pos-reconstruction
loop verbatim so gang members and BoundParam share one coordinate space.
Deviation ratified vs the plan: GangFault::KindMismatch carries structural
{node, name} coordinates instead of a stringly member label, consistent with
the sibling arms (plan amended). A redundant test-local fixture wrapper was
dropped after a fresh quality re-review of the blocked task diff.
Verified: cargo test -p aura-engine --lib 249/0, -p aura-core 53/0, clippy
-D warnings clean on both crates.

docs(cli,ledger): sweep #159 demo-retirement drift — stale comments + ledger notes
Cycle-close audit tidy for the #159 demo-retirement arc: behaviour-free reword of prose/comments/docs left pointing at symbols the arc deleted. Adversarially verified by the audit workflow; cargo build --workspace --all-targets green. - README: drop the removed `--harness` token; restrict the legacy built-in form claim to walkforward/mc/generalize (run/sweep no longer resolve one). - glossary: the built-in `--strategy` sweep surface is retired (#159), not a live inline path. - INDEX.md ledger: append [HISTORY] supersession markers (house style) to the dated realization notes advertising the retired `--harness` / built-in `--strategy` CLI forms (cost-flag #153, cycles 0065/0066/0067, name-res, #210 status); historical text preserved. - aura-engine test-fixture docs: drop dead cross-crate refs to the deleted aura-cli fns sample_harness / build_sample and the deleted `macd` composite. - cli_run.rs: reword the #159-cut-2 pin doc to the current clap generic-usage reality (no strategy_from / Strategy::RBreakout); r_sma_sweep_family -> blueprint_sweep_family. - verb_sugar.rs: fix the pre-existing `E[R]` unresolved-doc-link warning. Remaining tidy — the main.rs comment cluster plus its rustdoc link at :1546 (the second cargo-doc warning) — held for a follow-up issue. The dead cost-graph branch is tracked in #221. refs #159 |

feat(campaign,registry,engine): record widenings + preflight v2 fault set (0108 tasks 1-2)
Task 1: RBootstrap and Generalization gain serde derives; lineage.rs gains StageBootstrap (per_survivor | pooled_oos) and CampaignGeneralization; StageRealization.bootstrap and CampaignRunRecord.generalizations land serde-default sparse (a pre-0108 campaign_runs.jsonl line still parses — pinned), threaded None/empty through every literal site. No behaviour change. Task 2: ExecFault::UnsupportedStage is gone; the preflight now admits the v2 shape sweep [gate]* [wf]? [mc]? [generalize]? via a monotone rank walk (precise per-pair PipelineShape prose) and statically refuses: single-instrument generalize (GeneralizeNeedsInstruments), non-R generalize metrics via check_r_metric (GeneralizeNonRMetric — no fourth roster site), zero mc params (ZeroBootstrapParam). CLI prose swapped accordingly. The loop's E2E phase added a tier-boundary pin: process validate accepts [sweep, mc, walk_forward] while campaign run refuses it data-free. KNOWN RED (documented in the plan, flips in task 5): crates/aura-cli/tests/research_docs.rs::campaign_run_v1_boundary_refuses_mc_process still pins the retired 'not executable in v1' prose.

feat(engine,registry): ListSpace + campaign-run realization store (0107 tasks 2-3)
aura-engine: ListSpace — explicit point set implementing Space beside GridSpace/RandomSpace (a gate's survivor subset has no cartesian structure); GridSpace-identical arity/kind validation reusing the existing SweepError variants (KindMismatch.value_index carries the point ordinal for a list); empty point list is valid and sweeps to an empty family; re-exported at the crate root. aura-registry: CampaignRunRecord/CellRealization/StageRealization/ StageSelection — the thin campaign-level linking record over untouched family records (#198 decision 4) — with append_campaign_run (assigns run via next_campaign_run, a parallel counter beside next_run) and load_campaign_runs (missing file => empty) on the campaign_runs.jsonl sibling store; blueprint_path and find_blueprint_by_identity promoted to pub (the campaign executor resolves the same refs the referential tier validates).

feat(engine+cli): topology-identity hash — --identity-id beside --content-id
Engine (aura-engine/blueprint_serde): blueprint_to_json factored into build_doc/serialize_doc (byte-preserving — canonical golden unchanged) and blueprint_identity_json added: the canonical document with every non-load-bearing debug symbol (C23) blanked (composite name, instance names, bound-param names, role names, output re-export names) while everything load-bearing survives (type ids, node order, edges, role targets/order, output pairs/order, bound pos/kind/value — openness stays identity-bearing). Re-exported from lib.rs. Six property tests: renamed twins (equal identity, unequal canonical), open-vs-bound, bound-value, edge-swap, nested-composite interior names, role/output renames — the last two are additive beyond the plan and cover the recursion and role/output arms the planned four did not. CLI (aura-cli): graph introspect gains --identity-id, a sibling of --content-id through the same shared content_id SHA-256 primitive; composite_from_str factored out of build_from_str (fault strings byte-identical). The exactly-one introspect dispatch is DELIBERATELY relaxed: the two id flags form one group and may combine — one build, both ids, one per line, content id first. In-crate cross-path twin test (Rust sma_signal vs op-script twin: distinct content ids, one identity id) beside the existing cross-surface pins; four e2e tests incl. the previously uncovered count!=1 usage exit-2 path. topology_hash, the blueprint store, reproduce, and every --content-id byte stay untouched (spec acceptance 3; all existing pins green). Verification: cargo build clean; cargo test --workspace 884 passed / 0 failed (873 baseline + 11 new); clippy -D warnings clean; doc build 0 warnings. The implement-loop's Task-4 spec-compliance block was a plan-byte count mismatch only (plan under-counted pre-existing blueprint_serde tests 6-vs-7 and did not anticipate the two sibling-accepted extra tests); gates re-run by hand, all green. closes #171, refs #180 |

feat(project): the project-as-crate load boundary (cycle 0102)
A research project is now a loadable external cdylib crate. Inside a directory whose ancestry holds an Aura.toml, aura discovers the project root cargo-style, locates the compiled dylib via cargo metadata (debug default, --release opt-in), loads it load-and-hold, and refuses mismatches before trusting anything: the AURA_PROJECT descriptor (aura-core::project, #[repr(C)]) carries a C-ABI stamp prefix (rustc + aura-core version, baked per consuming build by the new aura-core build.rs) validated before any Rust-ABI field is read. The vocabulary charter gates the merged resolution: project type ids are ::-namespaced (std stays bare), duplicates refuse, and the enumerable type-id list must agree with the resolver, so introspection can never silently omit a project type. All blueprint verbs resolve through the merged project + std vocabulary via a per-invocation Env threaded through the dispatch chains; registry, trace-store, and data paths anchor at the project runs root (Aura.toml [paths], paths-only by design — instrument geometry stays the recorded sidecar, C15). RunManifest gains the Tier-1 project provenance field (namespace + dylib sha256 + best-effort commit), stamped beside topology_hash on the blueprint-run paths; pre-0102 registry lines load unchanged. Default node names strip the namespace, so :: never reaches the param-path address space. Proven by the demo-project fixture (built by the e2e via cargo, path-dep on this workspace): run twice bit-identical, provenance recorded, introspection lists demo::* beside std, registry anchors at the discovered root from a subdirectory; the badcharter fixture proves the charter refusal through the real libloading path; a never-built project refuses with a cargo-build hint. Outside a project every path collapses to the previous literals — goldens and manifest pins byte-identical. Verification: cargo build --workspace clean; cargo test --workspace 862 passed / 0 failed (incl. 7 project_load e2e); clippy -D warnings clean (one precedent-matching allow(too_many_arguments) on run_oos_blueprint, whose arity the Env threading raised to 8); doc build unchanged. Docs/ledger aligned: Aura.toml field lists are paths-only in project-layout.md, glossary, C16/C17; new C13 realization note records the per-invocation-reload reading and the load-and-hold one-shot scope boundary. New deps, per-case review (aura-cli leaf binary only, never the frozen artifact): libloading, toml. refs #180 |

feat(0092): run-from-blueprint infrastructure — restructure + topology_hash + shared seam (Tasks 1-3)
Cycle-1 infrastructure for #165 (World/C21). Behaviour-preserving + workspace green; the CLI arm + tests (Tasks 4-5) follow. Task 1 — restructured stage1_r_graph into stage1_signal() (the serializable signal leg: SMA-cross -> Bias, a `price` input-role + a `bias` output) + wrap_stage1r(signal, ...) (broker/sinks/exec/cost around a nested signal), with stage1_r_graph() = wrap_stage1r(stage1_signal(...)). DEVIATION from the plan's "callers untouched" claim, verified behaviour-preserving: nesting the signal prefixes its param-space names (stage1_signal.fast.length), which broke the sweep's bare .axis("fast.length"); fixed exactly as the #137 stop-knob machinery does — FAST_LENGTH_SUFFIX/SLOW_LENGTH_SUFFIX suffix-resolution + stage1_r_friendly_name arms mapping the prefixed names back to the bare manifest names. All observable behaviour (manifest names, member keys, metrics, traces) byte-identical; the flat graph and every metric unchanged (full suite green, incl. sweep/walkforward/MC). Task 2 — RunManifest.topology_hash: Option<String> (Tier-1 optional, serde default/skip — old manifests byte-identical, #156), threaded None into all 24 literal sites across 7 crates. Also fixed the aura-registry RunManifestRead read-mirror to carry topology_hash (it was hardcoding None on load) — else a stored hash would silently drop on the registry round-trip once Task 3 stores a real one. Task 3 — the shared run_signal_stage1r seam (hash the signal, wrap, compile with params, bootstrap, run, manifest with params from param_space + topology_hash) + the sha256_hex topology_hash helper (sha2 in aura-cli, off the frozen engine, invariant 8). run_stage1_r now carries its topology_hash too (every run becomes self-identifying, #158). The seam is unwired until Task 4 (transient #[allow(dead_code)], retired there); RED-first seam tests added. Verified: cargo test --workspace green (51 suites, 0 failures); cargo clippy --workspace --all-targets -D warnings clean. refs #165 |

test(graph_model): cover a producer backing >1 re-exported output field
#47 — close a coverage gap in the graph model serializer: a single interior producer node backing more than one re-exported output field was never exercised by a fixture (every existing one maps each output to a distinct producer or a single field). The issue was filed at cycle 0022 against `aura-cli/src/graph.rs`'s `render_definition` / `output_binding` helper, which rendered a textual `(n1, n2) := <producer>` tuple binding. That file and helper no longer exist — the textual definition renderer was replaced by the JSON model emission now in `aura-engine/src/graph_model.rs`, where the multi-OutField case is plain flat iteration over `c.output()` (one `[name,kind]` entry + one `#N` boundary binding per `OutField`, by `(node, field)`), not a special tuple-binding arm. So the original branch is gone; this guards the flat emission that replaced it. New test `multi_outfield_producer_emits_one_binding_per_field` (+ two fixtures): a two-field producer (`hi`:f64, `lo`:i64 — distinct kinds, so the per-field `field_kind` lookup is exercised) re-exported as both composite outputs, nested in a root so it renders through `composite_def_json`. Asserts both fields surface with their own kind (`"outputs":[["hi","f64"],["lo","i64"]]`) and both bindings reference the same producer at distinct ordinals (`0.o0`/`#0`, `0.o1`/`#1`). Test-only; no production code touched (the behaviour was already correct). Verified: cargo test -p aura-engine green (237 in the lib suite); clippy clean. closes #47 |

feat(0090): blueprint format forward-compat — Tier-1 tolerance pinned, two-tier discipline codified (closes #156)
The blueprint data format (C24) extends additively under one codified two-tier discipline: - Tier-1 (additive-optional): a new optional field/section is tolerated by an older reader (serde ignores unknown fields — no deny_unknown_fields), with no format_version bump; by C1 a new optional field defaults to prior behaviour, so an old blueprint reproduces the same graph. - Tier-2 (must-understand: a new node type, edge semantics, or structural-axis kind): bumps format_version, so an old reader refuses cleanly (LoadError::UnsupportedVersion / UnknownNodeType) rather than silently building a different graph. Most of #156 already shipped with #155 (cycle 0087): the envelope, omit-defaults canonical form, and both Tier-2 load-path refusals were present and green. This cycle pins the one previously-unproven property — Tier-1 forward-tolerance of an unknown optional field on the current loader — and codifies the discipline. Changes: - New characterization pin (in-crate, blueprint_serde.rs): unknown_optional_field_is_tolerated_byte_identically — an unknown optional key at doc and primitive level loads byte-identically and runs bit-identically. - Two public-seam E2E pins (blueprint_serde_e2e.rs, added by the E2E phase): unknown_envelope_field_tolerated_through_public_api and unknown_primitive_field_tolerated_through_public_api — split the two distinct tolerance surfaces (envelope vs primitive) across the World/cdylib crate boundary, where a deny_unknown_fields added to one would break forward-compat while leaving the in-crate test green. - LoadError::UnsupportedVersion doc reworded from the deferred "is #156" note to the settled two-tier discipline statement. - C24 ledger (docs/design/INDEX.md): Status codification sentence added; #156 dropped from Remaining (#158/#159 stay). Derived fork (recorded on #156): the per-section required-flag mechanism (PNG critical-vs-ancillary) is NOT built — the version envelope already gives the must-understand refusal at version granularity, no current Tier-2 section validates a finer scheme, and C1 holds either way. The pin is a characterization test (GREEN on first run) — it documents existing serde silent-ignore behaviour, no production code changed. Verified: cargo test -p aura-engine green (all targets, three new tests confirmed by name); cargo clippy --workspace --all-targets -- -D warnings clean. |

feat(0089): construction diagnostics read by-identifier (closes #162)
The cycle-0088 fieldtest found three presentation defects on the construction
op-script surface, all where the surface dropped out of its by-identifier register.
Presentation only — every fault still fires identically (same exit code, same
op/finalize attribution); only the rendered cause changes.
- Item 1 (finalize by-identifier). The holistic finalize fault leaked the raw
index Debug form (`UnconnectedPort { node: 2, slot: 1 }`). `GraphSession::finish()`
now translates the three reachable index-carrying CompileErrors into new
by-identifier OpError variants (UnconnectedPort{node,slot} / RoleKindMismatch{role}
/ UnboundRootRole{role}) using the session's `ids`/`schemas` and the composite's
`input_roles()` — the holistic gate calls (validate_wiring,
check_param_namespace_injective, check_root_roles_bound) stay byte-for-byte
unchanged (C24: no second validator; only the `.map_err` closures changed).
`aura graph build` now prints `finalize: slot sub.rhs is unconnected`.
- Item 2 (bind mismatch prose). `format_op_error`'s BadParam arm matches the
BindOpError variants instead of `{:?}`: `op 1 (add): param fast.length expects I64
but got F64`, matching the connect mismatch register.
- Item 3 (discoverable bind form). `introspect --node` shows the typed-Scalar bind
form: `param length:I64 (bind {"I64": <v>})`.
Item 1 spans both crates atomically (adding OpError variants forces the exhaustive
format_op_error match; the finish() translation flips behavioural test pins in both
crates). Five test touches: the two in-file unit tests, the two E2E twins plan-recon
found that the spec's testing strategy under-enumerated
(construction_e2e.rs, tests/graph_construct.rs), and a new unbound-root-role test;
the implementer added RoleKindMismatch / Ambiguous/UnknownParam coverage too. The
CLI finalize test was tightened (orchestrator) to pin `sub.rhs` and the absence of a
raw `node:` index.
Spec boss-signed on a grounding-check PASS (docs/specs+plans/0089). Verified: full
workspace suite + clippy green; the three messages reproduce exactly against the
built binary on the fieldtest fixtures.

fix(0088): reject dataflow cycles in construction build (closes #161)
The construction op-script service accepted a dataflow cycle and exited 0,
emitting a non-DAG blueprint — violating domain invariant 5 / C9 (the graph is a
DAG; the only feedback path is an explicit delay/state node). The cycle-0088
fieldtest surfaced it (fieldtests/cycle-0088-construction-op-script/FINDINGS.md).
The construction gate set had no acyclicity check: a cyclic interior-edge set
passed both the eager per-op gates and the holistic finish, so replay() returned
Ok. Fix: an eager reachability check at the connect op that closes the cycle —
GraphSession::closes_cycle(from, to) asks "does the `to` node already reach the
`from` node through the edges added so far?" and rejects with a new by-identifier
OpError::WouldCycle { from, to } ("connecting from -> to would close a cycle"),
threaded through the CLI's exhaustive format_op_error. The fault is attributed to
the offending connect op, consistent with the surface's eager per-op diagnostics.
Eager rather than a holistic topological check at finish: a cycle is closed by
one specific connect, and naming that connect is the sharpest by-identifier error.
RED-first: two tests pin the symptom (a 2-cycle a<->b and a self-loop), both red
before the fix and green after; the 19 existing construction tests, the full
workspace suite, and clippy stay green.
Scope is the cycle only. The validity-floor cases the fieldtest also noted (an
unfed declared source role, an output-less graph) are degenerate-but-well-formed,
not invariant violations, and are deferred (refs #161) pending the build->consume
edge (#28) that defines what a valid emitted blueprint must guarantee.

audit(0088): cycle close — drift fixes + C24 ledger refresh; close construction service
Architect drift review of cycle 0088 (#157, the introspectable fail-fast construction service: §A shared gate predicates, §B the GraphSession/Op/replay per-op surface + introspection, §C the aura graph build/introspect CLI). What holds (confirmed against the diff): no-second-validator (C24) — edge_kind_check is the single kind-check site called by both validate_wiring and GraphSession::connect, and validate_wiring / check_param_namespace_injective are reused verbatim in finish(); engine domain-free (invariant 9) — construction takes an injected Fn(&str)->Option<PrimitiveBuilder>, no registry, the closed match + std_vocabulary_types live in aura-std; topology-as-data / no DSL (C24/C17/inv 10) — the engine Op is serde-free, the OpDoc wire DTO is CLI-side, ops are static and non-Turing-complete; replay-equals-builder byte-identity (construction_e2e.rs) protects C9/C19/C23. Resolution: - fix (drift-med): the root-role-boundness gate was the one holistic check finish() re-implemented instead of sharing — extracted check_root_roles_bound (blueprint.rs) and called from BOTH compile_with_cells and finish(), so finish() now reuses ALL the holistic gates and the no-second-validator claim is literally true. Behaviour- preserving (same UnboundRootRole variant; unbound_root_role_is_rejected stays green). - fix (drift-med): removed the #![allow(dead_code)] on construction.rs — empirically unnecessary (the pub re-exported surface is reachable; clippy -D warnings green without it) — and its now-inaccurate comment (it claimed removal "when the consumer lands", but the consumer is a separate crate). Also tidied a stale graph_construct.rs module-doc line. - fix (ledger): C24 Status refreshed — #157 moved out of "Remaining" with a cycle-0088 realization note (the construction service: eager/holistic gate split, build-free introspection, emits the #155 blueprint); #159 reframed as paired with #157. - carry-on (debt-med, forward-noted): the std_vocabulary roster is now a third hand-kept copy (match + test list + std_vocabulary_types) and introspect --vocabulary escalates #160's gap to user-facing — noted on #160; still fails safe. - carry-on (scaling-low, forward-noted): the engine Op -> wire OpDoc direction is unguarded for future Op variants — noted on #156 (the format-extension track). No architect-sweep / regression script is declared in the project facts, so the suite is the gate: cargo test --workspace 51 suites green; clippy --all-targets -D warnings clean. Cycle drift-clean. Ephemeral cycle artifacts removed (lifecycle convention): docs/specs/0088-*, docs/plans/0088-*. closes #157 |

feat(0088): §A shared gate predicates — edge_kind_check, resolution helpers, try_bind
Iteration-1 §A of the construction service (#157): the surface-agnostic shared predicates the eager op-script path and the holistic finalize gates both call — no second validator (C24). - edge_kind_check (blueprint.rs): the per-edge producer/consumer kind check, lifted verbatim out of validate_wiring's edge loop into a pub(crate) fn that validate_wiring now calls — behaviour-preserving (same Bootstrap(KindMismatch) variant; the existing compile-time gate test stays green). - resolve_input_slot / resolve_output_field (builder.rs): the exactly-one-match name→index resolution extracted as pub(crate) fns over (&NodeSchema, &str), so the runtime-String op-script names share GraphBuilder's resolution; GraphBuilder delegates and maps to the unchanged BuildError variants. - try_bind + BindOpError (aura-core node.rs): the fallible Result twin of bind (bind keeps its panic contract and pinned messages verbatim; try_bind is a separate method reporting the same three conditions as values). - check_param_namespace_injective + validate_wiring widened to pub(crate) for the finalize-stage reuse by the upcoming GraphSession::finish (§B). Partial iteration: §B (the GraphSession/Op/replay surface + introspection) and the §A→§B integration land next (plan Tasks 4-8). compile_with_params / check_ports_connected are behaviourally unchanged. Full suite green; clippy clean. Plan correction folded in: Task 3's test originally referenced aura_std::Sma — infeasible inside aura-core (aura-std depends on aura-core; the reverse edge is a dependency cycle). Adapted to a local PrimitiveBuilder probe with identical assertions. refs #157 |

feat(0087): blueprint serialization & loader — close the graph-as-data loop
C24 first cut (#155): a blueprint — the param-generic, named graph-as-data a Rust builder produces — is now a first-class serializable data value with a canonical, versioned format, and the engine has the missing load path (data -> blueprint -> FlatGraph), not only the Rust-builder construction path. What ships: - `blueprint_to_json` / `blueprint_from_json` in a new `aura-engine` blueprint_serde module: a faithful serde DTO projection (the build closures dropped; re-derived on load), top-level `format_version` envelope, canonical compact JSON (struct field order, defaults omitted via skip_serializing_if). - A resolver seam: the loader is generic over an injected `Fn(&str) -> Option<PrimitiveBuilder>`; the concrete closed `match` over the aura-std vocabulary lives in aura-std (`std_vocabulary`), never in the engine (the engine stays domain-free: lib deps aura-core + aura-analysis only, never the node-vocabulary crate). This is C24's compiled-in closed-set referenced by type identity, NOT a dynamic/marketplace node registry (domain invariant 9). - serde derives on the serialized plain types (Edge, Target, OutField, Role, BoundParam, ScalarKind); BoundParam additionally re-exported from aura-core's root (an additive fix the plan's file list missed). Load-bearing scope decisions (derived, logged on #155): - Sinks are excluded from the serialized blueprint — a recording sink captures an mpsc::Sender (runtime identity, not param/topology, C19 value-empty); sink addressing is the C18-registry / #101 concern. The round-trip test attaches identical sinks post-load to both twins. - Construction-arg builders (LinComb(arity), CostSum(n), SimBroker(pip), Session(..)) are out of the round-trippable set: their structural args are a C20 structural-axis concern the param-generic format does not yet encode; an absent type_id fails the load cleanly (UnknownNodeType), never a silent wrong graph. #155's vocabulary is the 22 zero-arg aura-std builders. Additively extensible later (#156). Orchestrator hardening on review: the serializer now emits bound params in ascending original-slot order (mirroring the loader), so the canonical form is bind-order-independent — a precondition for content-addressing (#158). Identity today (every #155 node has <=1 param); holds by construction for future multi-param nodes. Acceptance (all green): a serialized blueprint runs bit-identical (C1) to its Rust-built twin; serializer/loader are inverse (canonical idempotence, incl. a recursive nested composite); unknown-type and unsupported-version fail named, never panicking. cargo test --workspace 748 passed; clippy --all-targets -D warnings clean. closes #155 |

refactor(0080): relocate FamilySelection/SelectionMode to aura-analysis (refs #136)
The last trading-domain types still defined in aura-engine's report module — the selection-provenance types FamilySelection and SelectionMode — move to aura-analysis, finishing the #136 goal of getting the trading types out of the engine. aura-analysis is the only non-cyclic home that removes them from the engine: RunManifest.selection: Option<FamilySelection> needs the type and the engine already depends on aura-analysis; aura-registry and aura-cli reach them unchanged via aura-engine's re-export (report.rs pub-re-exports them, lib.rs untouched). Their tests stay in report.rs (one round-trips through RunManifest, which stays in the engine) and reach the types via the re-export. Behaviour-preserving (C1): full suite 665/0 unchanged incl. the C18 goldens, clippy clean, only report.rs and aura-analysis/src/lib.rs change. Staying in the engine (trace-coupled, deferred to the World/C21 layer, not #136): RunManifest, RunReport, summarize. The aura-registry Metric/metric_cmp vocabulary stays in the registry by design — the registry is the trading selection layer, not the domain-free engine (the deflation statistics branch on metric identity, irreducibly domain). See the #136 thread for the rationale. |

refactor(0079): extract the trading-analysis leaf into aura-analysis (refs #136)
aura-engine is documented (C16) and named as the reusable, domain-agnostic reactive SoA substrate, yet `report.rs` concentrated the trading-domain analysis layer inside it. This cycle relocates the pure-domain leaf into a new `aura-analysis` crate (deps: aura-core + serde only), erecting the engine/domain seam before the Stage-2 broker milestone deposits more currency/position-event code into the same module. Behaviour-preserving (C1): the full workspace suite stays green unchanged (665 passed), including the C18 on-disk byte-identity goldens (cli_run, the registry legacy-line loads). Moved to aura-analysis (bodies verbatim — no float expression re-associated): RunMetrics, RMetrics (+ its hand-written PartialEq), the private r_col column indices + SQN_CAP, summarize_r, r_metrics_from_rs, derive_position_events, PositionAction (+ From/TryFrom<i64>), PositionEvent, and the deflation stats helpers inv_norm_cdf / expected_max_of_normals. Their unit tests and private helpers (r_row / r_row_full / pm_row) relocate with them — tests live with their subject (the r_col helpers reach the private module directly, which a re-export cannot bridge). Stays in aura-engine for this cycle: the generic trace plumbing (ColumnarTrace, join_on_ts, JoinedRow, f64_field), RunManifest, RunReport, and summarize (it bridges recorded trace columns into RunMetrics, so it is trace-coupled). The mis-placed orchestration types FamilySelection / SelectionMode also stay (their relocation is entangled with the registry-vocabulary fork, deferred). report.rs pub-re-exports the moved symbols, so aura-engine's lib.rs re-export block and every `crate::report::X` / `aura_engine::X` consumer (aura-registry, aura-cli, aura-composites, aura-ingest) compile byte-unchanged; only the new crate, the workspace member list, aura-engine's Cargo.toml dep, and report.rs itself change. Deferred to later cycles (genuine design forks, route through specify when reached): making RunReport generic over a metric type M and re-bounding sweep/mc/walkforward; relocating the aura-registry Metric / metric_cmp / rank vocabulary; relocating FamilySelection / SelectionMode. Fork decisions logged on #136. |

feat(0078): cross-instrument generalization as a validation step
Last piece of the Inferential-validation milestone (#146): a new `aura generalize` subcommand grades how consistently a single candidate holds across a set of instruments — the across-instrument axis of the same anti-false-discovery concern as trials-deflation (#144, within one family) and plateau-over-peak (#145, within one instrument's surface). Aggregator/validator, not a third selector (user-ratified): it runs a brought candidate (a single-cell stage1-r grid — --fast/--slow/--stop- length/--stop-k pinned to single values) across an instrument list (--real SYM1,SYM2,...), collects per-instrument R-metrics, and reduces them to a worst-case floor (min over instruments) + a sign-agreement count + the per-instrument breakdown. R-only (C10 — R is the only account/instrument-agnostic unit); the worst-case min is the cross- instrument sibling of PlateauMode::Worst and satisfies the non- domination constraint by construction (a strong instrument cannot lift a min). Rejected: a cross-instrument t-stat mean/std*sqrt(M), which reintroduces the pooled mean the milestone warns against. - RunManifest gains a first-class `instrument` lineage field (serde- widened, C14/C18 — legacy lines load as None, existing manifest bytes unchanged); the compat read-mirror threads it in lockstep. - FamilyKind::CrossInstrument (C12 comparison axis); the M per-instrument runs persist as a CrossInstrument family, each member self-identifying via its stamped instrument. The aggregate is recomputable from the members (McAggregate precedent), printed live. - The generalization reduction lives registry-side beside optimize_ deflated/optimize_plateau (C9), reusing resolve_metric/metric_value/ is_r_metric; check_r_metric is the data-free pre-check the CLI runs before evaluating any instrument. - Additive: existing sweep/walkforward/mc/standalone paths stay byte- identical (C23 — instrument omitted when None via skip_serializing_if). Verified by the orchestrator: cargo test --workspace green (0 failed — the new generalization_*, check_r_metric, parse_generalize_*, and the gated cross-instrument E2E all pass; the E2E ran the real GER40/USDJPY path on this host, exit 0); cargo clippy --workspace --all-targets -D warnings clean. closes #146 |

audit(0077): cycle close — drift addressed; legacy-load fixture + ledger sync; drop ephemera
Architect drift review over 9c6b9c7..cb32658 returned drift_found (3 items); all resolved here. What holds (architect): C23 default-argmax byte-identical, C9 separation (selector in aura-registry, walk_forward selection-agnostic), C1/C2 (plateau pure/deterministic/in-sample), one higher_is_better direction source. Resolutions: - [medium] Backfilled the pre-0077 FamilySelection legacy-load fixture (report.rs family_selection_loads_a_pre_0077_legacy_line). The feat commit and the struct doc-comment claimed "a legacy line still loads (C14/C18)" as landed, but no test pinned the field-level mapping: bare deflation scalars -> Some(...), absent plateau keys -> None. families.jsonl/runs.jsonl are append-only, so a winner stamped pre-0077 must read back; now pinned. - [low] Synced the ledger's inferential-validation open thread (docs/design/INDEX.md): #145 plateau-over-peak landed (cycle 0077), selection is now a pluggable objective (bare argmax -> trials-deflated -> plateau) on the manifest carrier; only #146 (cross-instrument generalization) remains of the milestone's three pieces. - [medium-high] Removed the cycle ephemera (git rm docs/specs/0077-*, docs/plans/0077-*) per the cycle-close convention. Regression: full workspace suite green and clippy --all-targets -D warnings clean (verified at feat-review time). No baseline scripts configured; the test + clippy gates are the regression gate. Cycle 0077 tidy (clean) — drift-clean, not a milestone close (the milestone fieldtest is a separate deliberate gate). |

feat(0077): prefer a robust parameter plateau over the in-sample peak
Add an opt-in plateau selection objective for walk-forward, recorded on the same RunManifest.selection carrier #144 introduced. Default argmax is byte-identical (C23); plateau is reached only via a new --select flag. What landed: - FamilySelection / SelectionMode reshape (report.rs): the selection RULE (mode) and its ANNOTATION are orthogonal — deflation fields become Option (present iff Argmax), plus PlateauMean/PlateauWorst variants and neighbourhood_score/n_neighbours (present iff Plateau*). Legacy lines still load: the deflation scalars deserialize from bare values via serde default (C14/C18). compat.rs embeds FamilySelection by value — reshape flows through untouched. - GridSpace::axis_lens() + SweepBinder::sweep_with_lattice (engine): the grid radixes in param_space()/odometer order. sweep() delegates to sweep_with_lattice with the lattice dropped, so every existing .sweep() caller is byte-unchanged. - optimize_plateau + PlateauMode + closed_neighbourhood (aura-registry, C9): each member scores as the mean/worst of its closed mixed-radix grid neighbourhood's metric_value; the winner is the smoothed argmax by the metric's direction (earliest-odometer tie, as optimize). Pure, no RNG (C1); in-sample only (C2). A higher_is_better helper now sources the per-metric direction once, shared by metric_cmp and optimize_plateau. - CLI --select <argmax|plateau:mean|plateau:worst> (default argmax; unknown token exits 2). walkforward_family dispatches via a select_winner helper; sweep_over/stage1_r_sweep_over carry the lattice as Option<Vec<usize>>. runs-family display gains a plateau(<mode>)=<score> over <n> cells line. RandomSpace-refuse: walkforward has no --random producer, so the plateau-without-lattice guard is structural — select_winner returns the refuse on a None lattice (the caller prints the message and exits 2), unit-tested at the helper, not via a --random E2E (decided + recorded on #145 comment 1974, with the lattice-seam fork). Tests: plateau-picks-plateau-not-spike, mean-vs-worst, lower-is-better direction-flip, closed-neighbourhood golden, single-member degeneracy, C1 determinism; CLI select-parse, select_winner refuse; E2E argmax-byte-identical (C23), plateau:mean and plateau:worst provenance. Full workspace suite green; clippy --all-targets -D warnings clean. closes #145 |

feat(0076): deflate the sweep winner's metric for the number of trials
Adds optimize_deflated beside optimize in aura-registry: the in-sample walk-forward selection now records, on each OOS winner's manifest, how much the winner's metric is inflated by the size of the search it won — a deflated score and (R arm) an overfit probability — without changing which member wins (additive, C23; a regression test pins optimize_deflated's winner == optimize's). - R arm (sqn_normalized/expectancy_r/...): a centred moving-block reality-check. Each member's per-trade R series is mean-subtracted to impose the no-edge null, resampled via the r_bootstrap kernel (extracted to a shared resample_block, byte-identical), and the best-of-K null-max gives overfit_probability = (count(null >= raw)+1)/(n+1) and deflated_score = raw - p95(null). Deterministic given the seed (C1). - total_pips arm: a closed-form expected-max-of-K dispersion floor (inv_norm_cdf + expected_max_of_normals), no probability. The record (FamilySelection on RunManifest) rides the proven serde(default, skip_serializing_if) widening + a compat.rs mirror, so legacy runs.jsonl/families.jsonl lines load unchanged and unstamped sweep/mc/standalone manifests stay byte-identical (C14/C18). The SelectionMode enum reserves a Plateau slot for #145. CLI: walk-forward stamps both arms; runs family <id> rank surfaces a human-readable deflated/overfit line. Quality review (re-dispatched after the implement-loop's quality gate exhausted) caught a real defect: on the R arm with positive resamples but no member carrying trade_rs (a family loaded from disk — trade_rs is serde-skipped), the null was all-NEG_INFINITY, turning deflated_score into +inf. Fixed by collapsing "no usable null" (zero resamples OR no trade_rs) into one degenerate floor (deflated == raw, overfit == 1.0); pinned by optimize_deflated_no_trade_rs_floors_instead_of_infinity. Verified: cargo test --workspace and cargo clippy --workspace --all-targets -D warnings both green. Frictionless Stage-1 R; n_eff advisory and reload-time recompute deferred (spec 0076 Out of scope). closes #144 |

audit(0075): cycle close — drift-clean; doc-link + trade_rs tripwire tidy; drop ephemera
Architect drift review (c99e7b8..2e77ab1) against the design ledger +
CLAUDE.md invariants: drift-clean, debt only — no contract or spec
violation. Verified intact: C18 wire shape (trade_rs is #[serde(skip)] +
excluded from the hand-written PartialEq; runs.jsonl/families.jsonl bytes
and digests unmoved; mc_r_bootstrap is a printed line, never a record),
C1 determinism (seeded r_bootstrap + disjoint walkforward windows, both
pinned by byte-identical-rerun e2e tests), C7 frictionless Stage-1
(round_trip_cost stays 0.0), C8/C12 streaming reduction (IS sweep folds
O(trades)/member, OOS run non-reduce). The verbatim summarize_r /
r_metrics_from_rs float duplication is guarded by the cross-reducer
equality test — sound.
Tidy applied this close:
- doc-link drift: the new E[R] notation in r_bootstrap / RBootstrap /
run_mc_r_bootstrap doc-comments was parsed by rustdoc as an intra-doc
link `[R]` (4 warnings). Wrapped in backticks; doc build now clean.
- coverage micro-gap [low, architect]: added a tripwire asserting a
populated trade_rs is absent from the serialized JSON (the serde(skip)
C18-preservation property had no direct test — only Vec::new() was
serialized before).
Carry-on (benign debt, not fixed): the mc usage literal carries a `usage:`
prefix the sibling sweep/walkforward usages omit — required because the
new `["mc", rest @ ..]` arm now handles the `--real` rejection and the
preserved golden asserts stderr.contains("usage"); churning the golden to
drop the prefix is not worth it.
Removed the cycle's ephemeral spec + plans (docs/specs/0075,
docs/plans/0075, docs/plans/0076) per the lifecycle rule.
Verified: cargo test --workspace 610 passed / 0 failed, clippy -D warnings
clean, cargo doc --no-deps clean.

feat(0075): Monte-Carlo R-bootstrap for OOS validation (iter 2)
Add `aura mc --strategy stage1-r [--real <SYM>]`: run the stage1-r
walk-forward, pool its OOS per-trade R series, and report a moving-block
bootstrap E[R] distribution / CI (one `mc_r_bootstrap` line with an `e_r`
quantile block + P(E[R]<=0)). Completes spec 0075's Monte-Carlo half on top
of iter 1's walk-forward R-reporting.
Engine: `r_bootstrap(rs, n_resamples, block_len, seed) -> RBootstrap` — a
deterministic moving-block bootstrap (non-circular, final block truncated;
block_len=1 = i.i.d. trade-shuffle; clamped to [1,n]; empty -> all-zero),
reusing the existing MetricStats/quantile and SplitMix64.
CLI: parse_mc_args/McArgs split — bare/`--name`/`--trace` route to the
unchanged synthetic seed-resweep `run_mc` (byte-for-byte preserved); the R
path accepts ONLY `--strategy stage1-r`, so a bare `--real` stays a usage
error (mc_rejects_real_flag_with_usage_exit_2 preserved, doc-comment
refreshed). run_mc_r_bootstrap reuses walkforward_family + RMetrics.trade_rs.
Corrective fixes over the plan snippets, both verified: the mc usage string
carries a `usage:` token (the new `["mc", rest @ ..]` arm now handles the
`--real` rejection, and the preserved golden asserts `stderr.contains
("usage")`); `#[allow(clippy::large_enum_variant)]` on McArgs keeps the
unboxed Stage1RGrid field layout.
Scope: single `--real <SYM>` per invocation; cross-symbol pooling is a
deferred follow-on (needs a multi-symbol grammar). Verified: cargo build
clean, full `cargo test --workspace` green (609 passed), clippy -D warnings
clean; bare `aura mc`, SMA walkforward, stage1-r single-run, and C18
round-trip goldens all preserved.
