A read-side cycle: `aura chart <family>` overlays one tap (default equity) of all
members of a sweep / MC / walk-forward family in one self-contained uPlot page,
consistent across kinds via the existing union-ts spine. The view consumes a
"set of runs to compare" (a family is its first producer) — the first step toward
the programmable analysis meta-level (C21), without rebuilding the orchestration
axes. aura-registry gains name_kind / read_family / ensure_name_free (a write-guard
making name resolution a total function); aura-cli gains the comparison ChartData
builder + emit_chart branch + --tap. aura-engine untouched (C9/C14).
Brainstorm-ratified, grounding-check PASS (11/11 current-behaviour assumptions
ratified by green tests). Signed under /boss on the grounding PASS.

Architect drift review (b92aab7..HEAD): the cycle is contract-clean — C9 (engine
untouched, whole change CLI-side), C6/C1 (real bars streamed from the pre-recorded
archive, real sweep byte-deterministic), C10 (refuse-don't-guess shared by run
--real and the family path), C12 (MC-exclusion fenced: mc --real exits 2). One
medium ledger-gap, now closed; one low item ratified as carry-on.
- Ledger: docs/design/INDEX.md C22 gains a "real-data family source" amendment
(#106) recording the opt-in real-data axis on sweep/walkforward families, the
DataSource provider, the MC exclusion (Fork A), and the oos{ns} key widening.
This was the only drift — a documentation gap, not code drift.
- Ratified carry-on [low]: the real walk-forward member key oos{from.0} is now an
epoch-ns integer; portable and collision-free, covered in practice by the
walkforward_real test (>=2 distinct oos<ns> dirs) and the 9-window E2E probe.
No explicit ns-uniqueness assertion beyond starts_with("oos") — acceptable; a
dedicated pin is not worth an iteration.
- Retire ephemeral spec/plan 0060 (git rm) per the cycle-artifact lifecycle; the
durable record is this ledger amendment + the git history.
No regression scripts configured (architect is the gate). Full workspace test +
clippy -D warnings green at close.
refs #106
Opt-in `--real <SYMBOL> [--from <ms>] [--to <ms>]` for `aura sweep` and
`aura walkforward`, mirroring `aura run --real`: each family member streams real
M1 close bars from the local data-server archive instead of the synthetic stream.
MC is excluded — its seed varies a synthetic price-walk realization, undefined
over real data (one realization -> identical members; a real MC needs a
bootstrap-resampling axis, its own cycle).
Engine, ingest, and registry untouched: a CLI-side `DataSource` provider replaces
the hardcoded `VecSource`. `M1FieldSource` already impls `Source`; `WindowRoller`
already rolls over epoch-unit timestamps.

Cycle-close tidy for the generic portable sweep member-key + bool-param demo
strategy (spec/plan 0059, reference issue #105, implementations 27f850d + 0b73a75).
Architect drift review (range 1d6fafb..HEAD): clean — no drift, no debt.
- C1 (determinism): varying_axes + member_key are pure functions of the grid
point, no schedule state; the engine carries no trace state (consistent with
the #104 design + the C22/#101 ledger note).
- C7/C8/C9: LongOnly is a clean one-in/one-out f64 node, None until warmed (C8
filter), the first bool *param* through the already-ratified Cell::bool()
path; momentum is an ordinary composite of existing nodes; brokers stay
downstream (C10). C18/C21/C22 upheld.
- The engine accessor exposes the binder's OWN axis-cardinality knowledge (it
holds the value-lists), not a presentation concern — formatting stays in the
CLI. The hand-rolled fnv1a64 mirrors the ledger-blessed SplitMix64 precedent
(harness.rs): tiny, dependency-free, bit-stable-on-purpose (std DefaultHasher
is unstable across releases; on-disk-name stability is the per-case C16
reason). LongOnly is a genuine universal aura-std block (long-only is
asset-agnostic). The ledger amendment matches the code.
Regression: the project declares no dedicated regression command; the gate is
the architect review plus the full suite, verified green at 0b73a75 (cargo test
--workspace, clippy --all-targets -D warnings).
Spec docs/specs/0059 and plan docs/plans/0059 retired (git rm) per the ephemeral
active-cycle artefact lifecycle; the durable rationale (the portable member-key
convention) lives in the ledger amendment (docs/design/INDEX.md C22/#101 note)
landed in 0b73a75.
closes#105
Generalises the family-member trace key (#105 foot-gun): derive it from the
axes that actually vary (not two hardcoded axis names), and render it as a
filesystem-conformant directory name on every major OS — charset [A-Za-z0-9._-],
case-less values (no case-insensitive-FS collision), length-bounded with an
FNV-1a fallback for the unbounded-grid edge.
Adds the first bool *param* node (LongOnly) and a momentum demo strategy
(Ema -> Sub -> Exposure -> LongOnly -> SimBroker) swept via a new
`aura sweep --strategy <sma|momentum>` selector — the empirical proof the
generic key works for a strategy whose params (incl. a bool) differ entirely
from the SMA-cross demo.
Boss-signed on the Step-5 grounding-check PASS (an independent fresh-context
agent): all 9 load-bearing current-behaviour assumptions ratified by green

Cycle-close tidy for family-member trace persistence (spec/plan 0058,
reference issue #104, implementation d3cb5f8).
Architect drift review (range 06fdafa..d3cb5f8): drift_found, low-grade
only — no contract violated. C1 (determinism), C7 (SoA), C8 (sinks),
C18/C21 (registry/families) all upheld; the opt-in --trace path is
genuinely byte-neutral. Two items, both resolved here:
- [high] Ledger gap: the C22/#101 disk-trace note recorded only the
single-run runs/traces/<name>/ layout. This cycle establishes a new,
load-bearing on-disk convention (per-member nested standalone run-dirs
runs/traces/<name>/<member_key>/) that the deferred family-comparison
view will build on. FIXED: amended the C22/#101 realization note in
docs/design/INDEX.md to record the layout, the content-derived
deterministic member keys, and the parallel-safe lock-free write.
- [medium] sweep_member_key hard-codes two grid axes; collision-free only
over today's built-in grid, a latent foot-gun if the grid varies an
unlisted axis. Not a current defect (one grid, covered, fail-loud on a
missing listed axis). CARRY-ON: filed #105 (idea) for generalised key
derivation when the grid generalises.
Regression: the project declares no dedicated regression command; the
gate is the architect review plus the full suite, verified green at
d3cb5f8 (cargo test --workspace, clippy --all-targets -D warnings).

firewall intact (main.rs byte-unchanged → build_chart_data still returns
ChartData{xs,series}, the injected window.AURA_TRACES payload shape untouched;
the ordinal index spine is derived client-side). C22 holds — the
ordinal/continuous toggle + wheel-zoom/drag-pan/dblclick-reset are view
affordances over a recorded trace (read-only setScale on the x range), not a
scene editor. The #102 manifest-header gap is neither closed nor regressed,
still tracked.
Regression gate: cargo test --workspace green (incl. the four chart guards +
render inline tests), clippy --all-targets -D warnings clean; aura has no

Cycle-close audit for the trace-charts visual face (#101, shipped across
8bb5256 persist + 15ee6d5 serve). Architect drift review (13941a2..HEAD)
+ the regression gate (cargo build/test/clippy --workspace, all exit 0,
orchestrator-verified).
What holds (carry-on): C14 clean — aura-engine/aura-core carry zero
UI/HTML/uPlot knowledge; ColumnarTrace does struct->encoding only, file
I/O in aura-registry, rendering in aura-cli. C1/C3 clean — persistence
and serve-time alignment are post-run pure reductions (join_on_ts at
serve time only, never in-graph). C7 clean — on-disk f64 columns +
kinds-tagged base types, the documented coercion honest, no 5th scalar.
Resolutions:
- [fix] Added the C22 realization note now that the web-from-disk seam
shipped (the amendment 3b56efb had deferred it to "when the seam
ships").
- [ratify] The served page injects the chart SERIES but drops the run
manifest (no run-context header) — a deliberate, defensible naive-viewer
scope call (the manifest is on disk in index.json; a header matters most
for the deferred families/comparison work, C21). The deviation from spec
0056 §1/§4 landed unflagged in 15ee6d5; it is now flagged here and
tracked as a follow-up. refs #102
- [tidy] Retired this cycle's ephemera (spec 0056, plans 0055/0056) and
the stale debris from the prior Runway close (spec 0055-fieldtest) per
the ephemeral-artifact convention; the durable record is the ledger +
git history.
Cycle drift-clean (modulo the ratified, tracked manifest-header gap).
refs #101
First cut of aura's visual face (issue #101; the web-from-disk pivot
ratified into C14/C22 this session, commit 3b56efb): tap arbitrary
recorder streams from a run, persist them to disk as columnar (SoA)
JSON, and serve them as a self-contained uPlot HTML chart — feeds
overlaid on a shared timestamp axis, or timestamp-aligned in stacked
panels. `aura run [--macd] [--trace <name>]` and `aura run --real <SYM>
... [--trace <name>]` persist; `aura chart <name> [--panels]` serves.
Both modes share one synthetic-union-spine join_on_ts alignment.
Signed via the specify auto-sign gate: the user is away under an
explicit "work fully autonomously, document decisions" mandate, so no
manual signature was available. All objective gates green (precondition
clean, self-review clean, grounding-check PASS), and a unanimous 5-lens
adversarial spec-skeptic panel (criterion / grounding / scope-fork /
ambiguity / plan-readiness all SOUND).
The panel earned its keep — two self-correction rounds to unanimity:
- Round 0 caught (a) panels shipped NOT timestamp-aligned, contradicting
the user's verbatim "aligned nach Timestamps in Panels" — corrected to
conform to issue #101 Fork A; (b) the USAGE advertised `--macd --trace`
with no dispatch arm — corrected to an orthogonal `--trace` composing
with every run form via a shared persist helper.
- Round 1 caught the union-spine -> join_on_ts mapping under-specified
(which tap is the spine?) — corrected with an explicit 3-step
synthetic-empty-spine mechanism (no privileged tap, no points dropped),
plus a to_rows uniformly-f64 clarification.
The two delegated naive-viewer decisions (per-series y-scale, union
spine) are documented with provenance on issue #101.

Milestone-close fieldtest for "Runway — real-data ergonomics & honesty
hardening". Four curated end-to-end scenarios derived top-down from the
milestone promise, run as a downstream consumer against real GER40/EURUSD M1
bars (public interface only; no crates/*/src read):
1. per-instrument pip honesty (#22) — GER40 index pip 1.0 AND EURUSD forex
pip 0.0001 both honest end-to-end; AAPL.US/FOOBAR un-vetted refused
exit 2, no stdout leak
2. real GER40 M1 open via open_ohlc from aura-ingest ALONE (#80/#81/#92) —
no data-server dep, 53173 real bars, C4 O/H/L/C order, ts-window inverse
3. multi-tap ts-join (#93) — two taps at different cadences, 27744 rows,
0 by-ts mismatches; warm-up None rows where a positional zip would corrupt
4. run-registry coherence (#73/#82) — list/rank retired exit 2, families/
family live, two-store Registry read-back + rustdoc
Findings: 4 working, 1 friction, 1 spec_gap.
- friction: Cell exposes only from_i64/from_f64/... while the side-by-side
Scalar is a tagged enum with public I64(..)/F64(..) variants. The natural
param-authoring entry point is Scalar (Cell is the hot-path buffer carrier),
so the wrong reach is a self-correcting compile snag — ergonomic only.
Filed as a follow-up idea.
- spec_gap: unknown family id exits 0 empty — ratified into the C18 note in
the preceding commit (treat-as-empty contract).
Gate verdict: GREEN. All seven axes mapped to a covering scenario and exercised
on real bars; both finding classifications and the one material coverage gap
were adversarially re-verified. That gap — #22's FX-vetted pip face, untested by
the original scenario set — was probed (EURUSD -> sim-optimal(pip_size=0.0001),
FX-scaled, not index-mis-scaled) and folded into scenario 1, so the pip promise
is demonstrated on both positive faces. Every scenario re-run independently on
HEAD before commit.
Audit (architect drift review + cargo test --workspace) clean: code matches the
spec, the engine stayed domain-free (no instrument identity in Ctx / the hot
path), InstrumentSpec sits beside the hot path per C7/C15. No regression scripts
configured (no-op gate); the full suite is green.
Ratify: the architect flagged one ledger-realization gap — C10/C15 described
per-instrument pip as standing design intent but carried no realization note for
the now-shipped channel. Added dated realization notes to C10 (the per-instrument
pip channel + the refuse-don't-guess honesty rule) and C15 (instrument specs as
metadata, first realized by InstrumentSpec/instrument_spec).

Cycle 0053 (multi-tap trace join on timestamp, #93) closes drift-clean.
Audit (architect drift review over 066638e..HEAD against docs/design + the
CLAUDE.md domain invariants):
- C8/C18 honoured: join_on_ts is a post-run reduction over recorded
(Timestamp, Vec<Scalar>) sink streams, a true sibling of summarize/f64_field
in the report layer — correct architectural home.
- C3 not violated: the join runs post-run over already-recorded output, not
in-graph; no as-of join smuggled into the DAG. C1 ts-uniqueness is a
documented precondition, not a runtime check — consistent with how the
engine leaves wiring-time invariants to contract.
- Option-per-side keeps the engine honest (reports presence; the consumer owns
the 0.0/-1/false defaults). The hand-rolled *_by_ts HashMaps are fully gone;
the two RED unit tests pin the #93 cardinality-misalignment + spine-drop.
- No drift, no debt, no ledger entry needs updating. Recommendation: carry on.
Regression gate: no dedicated regression scripts configured (optional per the
conventions); build/test/clippy --workspace --all-targets is the gate and ran
green — the gated GER40 byte-identity tests executed against the local archive
(not skipped), proving drain_trace's trace is byte-preserved across the
refactor.
Per the artifact lifecycle (committed while the cycle is live, git rm at cycle
close), the ephemeral spec and plan are retired here; their durable rationale
lives in the implementation commits 74324d1 / 35c5adc and the git history.
Ratified design for a reusable, spine-anchored join_on_ts helper in
aura-engine that fuses multi-tap Recorder traces on the recorded timestamp
(Option-per-side: the engine reports presence, the consumer interprets
absence). Refactors drain_trace onto it and documents the cadence rule on
the Recorder API. Resolves the #93 zip-by-index panic.

Cycle 0052 (real-data source-open seam, Runway-1) closes drift-clean.
Audit (architect drift review over aedaa5d..HEAD against docs/design + the
CLAUDE.md domain invariants):
- C3 (one ms<->ns crossing) strengthened — the inverse is seam-private and the
only consumer-side divide left; every consumer ns_to_ms / unix_ms_to_epoch_ns
wrap is gone.
- C4 (O/H/L/C merge tie-break order) now in exactly one vetted home (open_ohlc);
the hand-spelled four-field loops are gone.
- C12 (one shared Arc<DataServer>/cache) preserved; C7 surface additive.
- No drift, no debt, no ledger entry needs updating. Recommendation: carry on.
Regression gate: no dedicated regression scripts configured (optional per the
conventions); build/test/clippy --workspace is the gate and ran green — the gated
open_ohlc_seam behaviour-preservation test executed against the local archive
(not skipped), proving byte-identity vs the ms-path.
Per the artifact lifecycle (committed while the cycle is live, git rm at cycle
close), the ephemeral spec and plan are retired here; their durable rationale
lives in the implementation commit 8c9a1b4 and the git history.
Consolidate aura-ingest's OHLC source-open surface onto the engine-native
epoch-ns Timestamp currency: a private seam-owned inverse, a Timestamp-window
opener, a canonical OHLC bundle opener (fixed C4 O/H/L/C order), and a
DataServer/DEFAULT_DATA_PATH re-export + default_data_server convenience — so a
real-data source builds from aura-ingest alone, with the one ms<->ns crossing
owned by the seam. Behaviour-preserving (byte-identical RunReports).
Grounded against the tree via the ground-spec-0052 workflow (25/28 assertions
confirmed; compare.rs compiler-invisible site + AC1 scope fix applied).

Per-cycle specs/plans are step-scoped: every file maps to already-shipped
code, their snippets drift hard against current APIs (InputSpec->PortSpec,
Sim->Harness, schema() removed, C16 zero-dep reversed, ascii-dag retired),
and a stale spec read as an API reference misleads agents into non-compiling
code. No durable knowledge lost — rationale lives in the ledger + code
rustdoc, history in git + the tracker.

- delete all 117 existing specs/plans (recoverable via git history)
- CLAUDE.md: specs/plans are local-only ephemeral artifacts
The C12 realization and the 0041 spec claimed streaming residency is O(one chunk) at the process level ("a 20-year window streams in the same memory as a one-day one"). That holds only for the aura source ring (M1FieldSource::resident_records(), bounded by one chunk and correctly tested); whole-process RSS grows O(records-touched) because data-server's FileCache retains each window's parsed chunks (~56 B/record) read-only for the pass. Reproduced: 6 MiB @ 1mo -> 173 MiB @ ~10y, linear.
That retention is the replay-many optimization (load-once; close+volume share one parse via the field-agnostic FileKey), not a leak, and no always-on eviction can bound a single forward pass without regressing it. This narrows the docs/comments to the true per-source-ring property and names the FileCache per-window retention as the real, replay-amortized process cost. The streaming_seam assert is unchanged (it was always the ring bound; only its labelling confused ring vs process). The deferred opt-in non-retaining streaming read path is parked as Brummel/data-server#2.

Milestone spec: ship the GER40 session-breakout as a Composite blueprint so the
same strategy runs across backtest / sweep / walk_forward / compare without
re-authoring (the #94 fieldtest friction). Records the design decision that the
bar period is a structural axis (a construction arg binding both Resample and
Session, so a sweep cannot desync them — #96) and that the canonical shippable
strategy form is a Composite (FlatGraph is its compiled substrate). Authoring-
side; no engine-core change (the existing bind() + GraphBuilder + param_space()
layer already suffices).

Public-API research deep-dive driving the just-shipped GER40 real-data
session-breakout demo (5b5f034) through the escalating sequence a serious
researcher attempts next: scale to multi-year, walk-forward, structural-param
sweep, multi-instrument compare. Standalone consumer crate (path-deps only;
public interface = ledger + glossary + example corpus + cargo doc; no
crates/*/src read). All runs against the real /mnt/tickdata/Pepperstone archive.
Findings: 3 bugs, 1 friction, 3 spec_gap, 1 working. Triaged to the tracker:
- spec_gap: the flagship breakout ships as a raw FlatGraph the World API cannot
consume (sweep / walk_forward / compare all forced a hand re-author to a
Composite, which reproduced the FlatGraph numbers EXACTLY) — refs #94.
- bug: process residency is O(window) (6->173 MiB across 1mo->10y) despite the
documented O(one-chunk) claim; the aura ring stays <=1024 but data-server
retention scales, and streaming_seam.rs only measures the ring — refs #95.
- bug: the bar-period is one knob split across Resample (tunable param) and
Session (baked) and desyncs silently to 0.0 pips; Delay.lag leaks into the
default param_space (the C34 deform-vs-tune discriminator) — refs #96.
- spec_gap: the walk_forward empty-space idiom for param-free strategies is
undefined — refs #97.
- spec_gap (no per-instrument pip registry) and friction (one-directional
ns->ms conversion) re-confirm the known #22 and #80.
- working: C1 determinism over 7y / 148k bars, the lazy streaming source, and
the sweep/WFO cores held under real multi-year load; the Composite re-author
was behaviour-preserving (C23).

Milestone-close gate for "The World, part II — orchestration families".
Four end-to-end scenarios derived top-down from the milestone promise,

API + CLI only (no crates/*/src read):
- mw_3 (headline): real EURUSD-M1 walk-forward composing all four axes
(grid sweep + optimize in-sample, OOS stitch) over the M1FieldSource
seam + lineage — 5 windows, 145 200-pt stitched curve, C2 held.
- mw_2: monte_carlo over 128 seeds, reproducible McFamily (C1) + aggregate.
- mw_1: random sweep -> optimize -> 64-member lineage round-trip.
- mw_4: family-lineage CLI transcript.
Findings: 4 working (promise empirically delivered), 1 bug, 3 friction.
- bug F5: `aura runs list`/`rank` cannot read a pre-0047 runs.jsonl — the
cycle-0047 typed-Scalar params migration (86746e3) left the persisted
flat store unmigrated; load() fails at the first bare float (+ exits 0).
- friction F6: no epoch_ns_to_unix_ms inverse for real-data walk-forward.
- friction F7: DataServer/DEFAULT_DATA_PATH not re-exported by aura-ingest.
- friction F8: family store is directory-keyed, undocumented on Registry::open.

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

Settled-design spec for the walk-forward param-plane cut: WalkForwardResult gains space: Vec<ParamSpec>, WindowRun.chosen_params Vec<Scalar> -> Vec<Cell>, walk_forward takes the space by value (Fn-closure generic untouched), and param_stability schema-checks a per-slot coercer (Bool -> 0/1, Timestamp unreachable per C20) before a type-blind reduction, deleting scalar_as_f64 + its per-value unreachable.
Behaviour-preserving (C1): param_stability yields identical MetricStats over the existing fixtures.

`F: Fn(&[Scalar]) -> RunReport + Sync` stays byte-for-byte (honours #52's
#71-firewall constraint, so RandomSpace plugs in with zero reconciliation).
The lossy f64 collapse moves into the manifest constructor; the view stays
typed. Behaviour-preserving; SweepPoint and enumeration untouched.
Design ratified in-context (brainstorm, approach C over A, free function
over a NamedPoint type); a reconciliation comment on #57 records the
resolved forks with provenance. Human sign-off after the auto-sign panel's
grounding lens caught a blast-radius undercount in the first draft —
corrected to all eight sim_optimal_manifest call sites plus the
aura-registry SweepFamily struct-literal.

Persist sweep / Monte-Carlo / walk-forward runs as named, linked families
(C18 lineage / C21): a FamilyRunRecord stamps each member with a shared
family_id = "{name}-{counter}" in a sibling families.jsonl store, group_families
re-derives a family as a unit, and the CLI gains aura mc + family-aware aura runs.

Walk-forward orchestration: a WindowRoller rolls (in-sample, out-of-sample)
splits over a time span, walk_forward runs a disjoint harness per split via the
shared run_indexed core (C1), and stitches the OOS pip-equity segments into one
continuous curve. The varying dimension is the data window (axis 3), realized
eager-agnostically (#71): the public surface carries WindowBounds + a per-window
closure, never a materialized stream Vec; C2 no-look-ahead is a pure bounds
invariant (oos.0 > is.1), checkable with zero ticks.
The in-sample optimize (axis 2) is closure-supplied, not called by the engine:
aura-engine cannot depend on aura-registry (C9), and C12 forbids baking search
policy into the primitive. The CLI bridges both crates in run_walkforward.
Param-stability shape (the load-bearing fork) resolved with the user as R2:
on-demand, not stored. WalkForwardResult stores only raw per-window outcomes +
the stitched curve; param_stability(&result) -> Vec<MetricStats> is a public
on-demand reduction over the retained per-window chosen params (sweep-precedent:
summaries computed on demand, not cached, vs McFamily's stored aggregate). A
stored summary would be recomputable from the raw windows (redundant) and would
force one statistic canonical when "stability" admits several. Recorded with
provenance in the #69 reconciliation comment. MetricStats::from_values is
extracted from McAggregate::from_draws (behaviour-preserving; the 7 mc tests
guard) so the MC aggregate and the helper share one reduction. Empty OOS segment
contributes 0.0 to the stitch offset (mirrors summarize's unwrap_or(0.0)).
Gates: Step-1.5 precondition clean (no fork silently picked), self-review clean,
grounding-check PASS (twice — re-run after each edit). Auto-sign panel escalated
on the scope-fork design lens (param-stability shape) to human sign-off; the user
resolved it (R2), so this is a user-signed spec, not boss-signed.

C12 axis 4: Monte-Carlo as a sweep over seeds. `monte_carlo(base_point, seeds,
closure) -> McFamily`, the analog of SweepFamily, reusing the disjoint-parallel
executor (extracted into a shared `run_indexed` core) rather than forking a new
run loop. Each realization is a disjoint C1 unit; parallelism is across draws.
The aggregate (V1) covers all three run metrics with mean + p5/p25/p50/p75/p95,
a pure post-run reduction over the retained raw draws.
Eager-agnostic firewall (#71): the API takes seeds + a per-draw closure, never a

"Compilat" (German "Kompilat") was a coined noun for the product of the
bootstrap compilation — neither English nor a natural fit. The runtime
artifact already has a code identifier for exactly this thing: the
`FlatGraph` struct (harness.rs). Replace the coinage with that identifier:
- prose mentions -> "flat graph" (mirrors the type, reads plainly)
- definitional anchors -> `FlatGraph` (C11, C23, the running-graph line)
- `render_compilat` -> `render_flat_graph` (historical render symbol;
keeps the `render_blueprint` / `render_flat_graph`
source-vs-product pairing)
- `intra-compilat` -> `intra-graph`
- `from_compilat` (test) -> `from_flat`
"compilation" / "re-compilation" / "bootstrap-as-compilation" (the process,
ordinary English) are deliberately left untouched. Behaviour-preserving:
only comments, design ledger, specs/plans, one test-local variable and its
assert messages change. Full workspace test suite green; clippy clean.
The boss-signed 0040 spec's blast-radius section claimed "exactly three" flipping
tests, named from a hand-trace. A throwaway probe (the check implemented, full
workspace suite run, then discarded) found FOUR: the three named negative tests plus
`param_space_mirrors_compiled_flat_node_param_order_under_nesting`, a compile-success
param-order test that today compiles a deliberately under-wired nested graph (LinComb's
two term inputs never wired) just to read its flat param order. The new check rejects
it where it currently returns Ok.
Correction is editorial, not a design change: the check itself is unchanged. The
fourth test's fix differs from the three negative tests — it needs the contrived graph
fully wired (fan fast_slow's output into both LinComb terms + a covering root role),
not just a covering role — so the §Blast radius and §Acceptance criteria now enumerate
all four with their distinct fixes. Verified empirically (119 passed, 4 failed; every
other crate green), the strongest possible grounding for the count.
refs #65
Reject graphs with an unwired or double-wired interior input port. A new
name-free structural check `check_ports_connected` in `validate_wiring`
(crates/aura-engine/src/blueprint.rs) requires every interior node's every
declared input slot to be covered by exactly one wiring act — one `Edge{to,slot}`
or one `Role` `Target{node,slot}`, counted uniformly. Zero coverage is the new
`CompileError::UnconnectedPort` (a forgotten connection that today bootstraps a
silent empty column, harness.rs:137-148); more than one is `DoubleWiredPort` (a
slot holds one column). Run once at the existing compile boundary and recursive
per nesting level, so both the raw `Composite::new` and the `GraphBuilder::build`
surfaces inherit it. Index-based, name-free — the compilat is untouched (C23).
Narrowed scope of #65: the original "promote names to load-bearing wiring keys /
close the exposure-price swap structurally" goal is dropped (see the reconciliation
comment on the issue) — #64 already moved authoring to handles + visible port
names, so the residual same-kind swap is a valid-but-wrong name choice no
structural check catches, and a structural fix would push domain semantics into
the domain-free engine (C10/C7). This cycle ships only the name-free half that
stands on its own.

Surface a bind-bound param in the graph model and the `aura graph` viewer
signature instead of dropping it. A node built with `.bind(slot, value)` keeps
the slot off the tunable surface (param_space / sweep axes — unchanged, correct)
but now ANNOTATES it in the render: all slots shown, the bound one as `name=value`,
dimmed. The cycle-0036 `blend` renders `LinComb[weights[0], weights[1], weights[2]=0.5]`.
Structurally a twin of cycle 0035's instance-name thread: a conditional field
(here `"bound"`) threaded engine -> model -> viewer, plus goldens and a headless
render guard. Render/debug surface only — dropped at lowering (C23), model stays
deterministic (C14).

Surface a node's explicit instance name in the `aura graph` viewer: a named leaf

declaration prefix), an unnamed leaf keeps the bare `SMA[length]`. The name
crosses two surfaces — a conditional `"name"` field in the JSON graph model
(engine half) and a `cellLabel` prefix in graph-viewer.js (viewer half).
Explicit-`.named()`-only; `node_name()`'s lowercased-type default is not
surfaced. `named()`'s non-empty rule is kept with its code unchanged, its doc
re-grounded to the load-bearing invariant (knob-address segment + Some/None
prefix switch).

Add PrimitiveBuilder::bind(slot, value): fix a node param as a structural

Settled direction (Option B, builder-level): .bind() shrinks the builder's
declared param surface and wraps its build closure to re-splice the constant;
the construction layer (collect_params/lower_items/param_space) is unchanged
because both already key off builder.params(). Addressing is by-name
(authoring address space, C23/0032); compilat stays index-wired.

Test 5's asymmetric-collision fixture asserted a root-level param_space
["sma.length"] while also being "test 2's fixture with one leg swapped" (nested)
— a contradiction: check_fan_in_distinguishability only descends into composites,
so a root-level collision is not rejected today (not RED-first). Caught at plan
time while writing the verbatim fixture body.
Corrected: test 5 nests the asymmetric collision in an inner composite `asym`
(param-bearing Sma "sma" + paramless Pass1 .named("sma") + Sub, both leaves on
role price fanning into the Sub) under a source-bound root, asserting
param_space() == ["asym.sma.length"] (the single injective entry — the paramless
leg contributes no path) and that compile_with_params(&[I64(2)]) is Ok after.
Re-grounded PASS, re-panel unanimous SOUND. Forward correction on top of 7f059d0
(main is forward-only — no rewind of the boss-signed spec).
refs #59
param_space() injectivity becomes a stated, enforced compile invariant. One
structural check (check_param_namespace_injective) replaces the fan-in machinery
(check_fan_in_distinguishability, check_composite_fan_in, signature_of,
leaf_has_param) and the AmbiguousKnob binder branch. The error is path-carrying
(DuplicateParamPath) and the binders run the check before name resolution, so the
canonical by-name author sees the structural cure (.named(...)) instead of the
AmbiguousKnob symptom. param_space() stays infallible; the invariant lives in the
compile step (C23).
Two render-identity-only fan-in rejections (asymmetric param/paramless collision,
role-vs-leg signature collision) are intentionally dropped — neither is a
param_space duplicate (every knob keeps a unique path), and the property they
guarded (render distinguishability) has had no live consumer since the renderer
was retired in 0026. The larger is pinned by a now-compiles fixture.

Per-cycle fieldtest of node-instance naming (#56), driven as a downstream
consumer from the public interface only (ledger + spec + rustdoc + CLI; no
crates/*/src read), three fixtures built and run from HEAD.
Verdict: the core 0031 promise holds first-try. A consumer authors
Sma::builder().named("fast"), inspects param_space() (sma_cross.fast.length),
binds by name and runs; the default-name case (sma.length / exposure.scale,
verbatim lowercase) and paramless-interchangeable-stays-legal both hold.
0 bugs, 3 working, 2 friction, 1 spec_gap. The one real gap (verified by the
orchestrator against the fixture output): the spec's headline forcing function
IndistinguishableFanIn does NOT reach an author on the canonical
.with(...).bootstrap() flow. An un-named 2-SMA cross emits a literal DUPLICATE
knob (sma_cross.sma.length x2); the binder resolves names before the compile
fan-in check, so the author hits UnknownKnob / AmbiguousKnob("sma_cross.sma.length")
— which point at the knob, not at the cure "name your nodes". IndistinguishableFanIn
only surfaces via the positional compile_with_params path. Rejection still
happens (no invalid blueprint runs), so it is an ergonomic/signposting gap, not
a correctness bug. Routed to the backlog (relates to #58); 0031 stays
audit-closed. Minor: FlatGraph/Harness lack Debug, so a bootstrap Result can't
be {:?}-printed.
Design spec for #56 — give every blueprint node a name so param-space
path-qualification and fan-in distinguishability both flow from one
author-controlled identity, and retire the index-addressed ParamAlias overlay.
A primitive builder gains an optional name (default = the node's type-label
string, ASCII-lowercased verbatim: "SMA"->"sma", "SimBroker"->"simbroker";
explicit names must be non-empty). param_space() becomes uniformly
<node>.<param> at every level including the root. signature_of and the C9
fan-in rule re-key onto the node name: two same-type siblings both defaulting
to "sma" collide and IndistinguishableFanIn fires correctly, so one act —
naming the legs "fast"/"slow" — fixes both the naming collision and the fan-in
check. ParamAlias / Composite.params / the alias index-check are removed
(Role.name and OutField.name untouched). Ledger C9 and C23 amended. One
cohesive iteration: the engine mechanism + in-workspace migration (CLI sample,
engine tests, sweep goldens, graph_model.rs, sweep.rs, lib.rs re-export) land
together since removing the struct is compile-coupled; fieldtests/ are frozen
non-workspace records, out of scope.

render-marker claim (the marker was removed in cycle 0020), and an
under-specified compound default name — all corrected and re-grounded before
the unanimous pass.

Milestone-scope fieldtest (closing functional gate) for "The World —
parameter-space & sweep" (issues #30-#36). Three curated end-to-end scenarios
derived top-down from the milestone promise, driven from the public interface
only (ledger + specs + rustdoc; no crates/*/src read), built and run from HEAD
via a downstream consumer crate.
Delivery verdict: GREEN. The milestone delivers its promise.
- mw_1 single run bound by name: .with("sma_cross.fast", 2).bootstrap() binds
and runs (12 equity rows); diagnostics precise and knob-named (UnknownKnob /
AmbiguousKnob / KindMismatch).
- mw_2 named-axis sweep + compare: .axis(..).sweep(run) yields a 4-member,
ordered (odometer), disjoint, non-constant SweepFamily; ranking from public
fields. CLI (aura sweep / aura runs rank) delivers the same with no Rust.
- mw_3 structural-constant negative space (deliberate): SMA2-entry's
definitional `2` has no honest expression today -> grounds #55. Out of
milestone scope; not a blocker.
Findings: 0 bugs, 2 working, 3 friction, 1 spec_gap. Verified independently
(re-ran all three from HEAD; confirmed a plain SMA-cross emits sma_cross.length
twice and the shipped CLI sample carries the fast/slow ParamAlias overlays).
Friction (routed to the forward queue, none blocks the gate):
- the promised sma_cross.fast/.slow names are not free — they require
author-added ParamAlias overlays, doubly mandatory because the canonical
2-SMA cross also will not bootstrap without them (IndistinguishableFanIn);
- the sweep closure drops back to positional bind + manual name re-zip.
spec_gap -> #55: the wished-for structural-constant consumer code is recorded
in mw_3 as #55's acceptance evidence.
This commit is the milestone fieldtest itself; it closes no issue. Closing the
tracker milestone stays a deliberate manual act on this green gate.
Bind a blueprint's open knobs by name via a fluent builder instead of a
positional, Scalar-wrapped Vec in param_space() order: a single run as
bp.with("sma_cross.fast", 2).with("scale", 0.5).bootstrap(), a sweep as
bp.axis("sma_cross.fast", [2,3]).axis("scale", [0.5]).sweep(run). A pure
authoring layer over the existing bootstrap_with_params / GridSpace / sweep
primitives; the engine core is untouched (C1/C7/C12/C19/C23 preserved).
Ratified design (brainstorm -> specify):
- Fluent builder (.with()/.axis()), not a macro — C10 builder-API idiom.
- Raw literals via Into<Scalar>; the literal fixes the variant (2->I64,
0.5->F64); kind-check is pure equality, no coercion.
- Match key = the EXACT param_space() name (user's Option 1): path-qualified
for composite-interior knobs (sma_cross.fast), bare for root-level knobs
(scale). Short bare names are an authoring choice (promote to a root leaf),
not a job of this layer; no engine change, no unqualified matching.
- .with() not .bind() — bind is reserved for #55's structural-constant overlay.
- Total error order (a-f) over a single BindError vocabulary: Phase 1 validates
bindings (UnknownKnob/AmbiguousKnob/EmptyAxis/DuplicateBinding), Phase 2 walks
slots (MissingKnob/KindMismatch); first failing check wins; sweep kind-check is
per-element, making resolve_axes a superset of GridSpace::new so the downstream
.expect() is infallible.
- Two iterations: single-run side, then sweep-axis side (shared name-resolution
core). The CLI sample stays nested (user's call); the worked example shows both
qualified and bare names honestly, no fixture change.
Auto-signed under /boss spec_auto_sign after the objective gates (precondition,
parse no-op, grounding-check PASS) and a unanimous five-lens spec-skeptic panel.
The panel hardened the spec across five rounds: it corrected the worked-example
names to the real param_space() output, pinned the exact-name match key, and made
the error precedence a total order closing a sweep per-element panic path. The
literal-inference grounding gap was closed separately by e97906a. Two design
points were taken by the user directly (Option 1; keep the sample nested).
