Three tasks. Task 1 (#113, compile-atomic): RED-rewrite the lookup test to the
six-field shape + invariant/uniqueness tests, then extend InstrumentSpec and
populate the vetted table for the five instruments (refuse arm stays). Task 2
(#114, greenfield): RED the round-trip / try_from-Err / serde-bare-int / reversal
tests, then add PositionAction (serde-as-i64) + PositionEvent in report.rs and
re-export from the crate root. Task 3: workspace test + clippy gate.
Recon-grounded line anchors; the redundant std::convert::TryFrom import dropped
(2021 prelude). INDEX.md realization-note drift (C10/C15 "minimal today") deferred
to the cycle-close audit, not folded here (code-only scope).

Cycle-close tidy for visual-world-cut-2 (decimation #108 + run-context header #102).
Architect drift review (53eeba5..HEAD): the only drift was a STALE LEDGER — the C22
section still listed #102 (run-context header) and #108 (decimation) as deferred/open
after they shipped in 476342d. Resolved in this commit:
- the #101 first-cut note no longer claims "not yet a run-context header";
- a new "served-page hardening — cut 2" amendment records #102 (ChartMeta +
buildHeader, family window = span across members) and #108 (the pure decimate
min-max transform) as landed, both CLI-side (C14);
- the "Open architectural threads" list drops the now-landed run-context header.
Substantive gates (self-verified): C14 honoured — all decimation/header/pixel logic
is in aura-cli (render.rs/main.rs/chart-viewer.js); the only engine touch in range is
the one-line #100 cell.rs doc. C1 preserved — decimate is pure, deterministic
bucketing over the sorted-deduped spine, no-op under budget, monotonic spine (pinned
by a unit test). Regression: cargo test --workspace = 446 passed / 0 failed; cargo
clippy --workspace --all-targets -D warnings clean. No separate baseline script.
Residual debt filed as #110 (idea): the decimation budget is a fixed const (no
--width flag), and the min-then-max sub-pixel ordering is a real ts-displacement in
the non-default continuous x-mode. Both are local aura-cli refinements, neither a bug.
Ephemeral spec/plan removed at cycle close (docs/specs/0062, docs/plans/0062).
Cycle 0062 tidy: drift-clean after this ledger amendment.
Three tasks on the aura-cli render path + a workspace gate:
- Task 1 (#102, compile-atomic): ChartMeta + ChartData.meta, built from RunManifest
in build_chart_data/build_comparison_chart_data (gain a `name` param), every call
site threaded (emit_chart + 3 comparison unit tests + the render test helper), the
manifest re-injected into window.AURA_TRACES, the negative render pin flipped.
- Task 2 (#102): #ctx CHART_HEAD slot + a pure buildHeader in chart-viewer.js with a
node-driven headless guard pair (chart_viewer_header.{mjs,rs}).
- Task 3 (#108): a pure decimate(ChartData, buckets) min-max transform applied in
emit_chart on both paths; engine + registry untouched (C14).
- Task 4: cargo test --workspace + clippy -D warnings.
refs #108
refs #102
Architect drift review over 99fd32b..HEAD (the housekeeping commits #99/#98 plus
the 0061 cycle): code drift-clean. Engine untouched (aura-engine + aura-core diff
empty — C9/C14); C21 realized faithfully (the comparison view consumes a set of
runs, a family is the first producer, no orchestration-axis rebuild); C18/C10
refuse-don't-guess honoured (every new error path exits 2, never panics; all six
tracing entry points guarded before persist, so name resolution is total). The only
finding was a ledger-realization gap, lifted in this commit.
Ledger (docs/design/INDEX.md): added a C22 amendment recording the
families-comparison view as realized (#107) — aura chart <family> overlays one tap
across a family's members on a shared y-scale, union-ts spine giving one mechanism /
three correct readings, the write-guard totalising name resolution; reconciled the
two stale "families-comparison ... remain open" lines (the #104 note and the
open-threads list) and named the deferred follow-ons (#102 run-context header, #47
multi-column tap selection, the orchestration-composability rebuild).
Regression: cargo test --workspace green (no failures), clippy --workspace
--all-targets -D warnings exit 0, cargo build --workspace clean — verified by the
orchestrator before close. No baseline to update (aura's regression gate is the
gated determinism suite, which is part of the workspace tests).
Retire the cycle's ephemeral spec + plan (0061). refs #107
Three tasks: (1) aura-registry — NameKind/FamilyMember/WriteKind, name_kind,
read_family, ensure_name_free + a NameTaken error variant; (2) aura-cli — the
comparison ChartData builder (shared y-scale, union-ts spine), filter_to_tap,
parse_chart_args, the emit_chart name-kind branch, the --tap flag, USAGE; (3)
aura-cli — the write-guard calls in the six tracing fns + collision tests. Each
task RED-first with per-crate gates; workspace test + clippy at the close.
refs #107
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
Five compile-gated tasks for spec 0060: (1) additive DataSource/DataChoice
provider + ns roller constants, (2) pip-parametrize the two blueprints + thread
all callers, (3) thread &DataSource into the five family builders + run_sweep/
run_walkforward (dispatch passes Synthetic), (4) --real parser grammar +
build-or-refuse dispatch + USAGE, (5) gated real-path integration tests + full
suite + clippy. Each task threads its signature change with all callers so
`cargo build -p aura-cli --all-targets` is green per task; the byte-unchanged
synthetic path is the regression guard.
refs #106
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
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).
Spec docs/specs/0058 and plan docs/plans/0058 retired (git rm) per the
ephemeral active-cycle artefact lifecycle; durable rationale lifted to
the ledger amendment above.

Three tasks (MC, sweep, walk-forward) wiring per-member trace persistence
into the family closures + a full-suite/lint gate. Each task threads its
builder signature and every caller together so the workspace compiles

refs #104
Architect drift review over 5bff7e0..HEAD: clean, no drift, no debt. C14/C7
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
separate regression script, so the suite + architect are the gates. cycle
clean.
Spec/plan 0057 retired per the ephemeral-artifact lifecycle (durable record:
the feature commit 45cc1c4, the #103 decision-log comments, and git history).
refs #103
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
Iteration-1 (persist half) plan for spec 0056: ColumnarTrace (aura-engine), TraceStore (aura-registry), and the shared persist_traces helper threaded into all three run forms. RED-first; Task 3 folds all nine signature-change callers in before the build gate (per plan-recon's compile-gate warning). Serve/chart half deferred to iteration 2.
refs #101
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).
Retire the ephemeral cycle artefacts (spec 0054, plan 0054) per the active-cycle
lifecycle. Deferred follow-up: #98 (route the runnable GER40 examples through the
lookup).
refs #22
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.
Bite-sized execution plan for spec 0053: Task 1 the join_on_ts helper +
JoinedRow + two RED unit tests in aura-engine report.rs (re-exported from
lib.rs); Task 2 the behaviour-preserving drain_trace refactor onto the helper;
Task 3 the Recorder prose cadence/join note. Final gate is workspace
build/test/clippy.
refs #93
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.
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.
- gitignore docs/specs/ and docs/plans/
- delete all 117 existing specs/plans (recoverable via git history)
- CLAUDE.md: specs/plans are local-only ephemeral artifacts
Five bite-sized tasks for the RandomSpace cut: (1) the Space trait +
behaviour-preserving generalization of sweep/sweep_with_threads, (2) typed
ParamRange, (3) RandomSpace::new validation + three SweepError variants,
(4) SplitMix64 -> pub(crate) + the seeded sampler, (5) public exports +
random-sweep integration. Each task is RED-first with single-substring test
filters; the grid suite is the C1 behaviour-preservation regression guard.

Two-task execution plan for spec 0048: Task 1 lands the whole aura-engine/walkforward.rs cut atomically (struct shapes, walk_forward seam, param_stability rewrite, scalar_as_f64 deletion, fixture migration, new Bool-slot test) gated on a crate-only `cargo test -p aura-engine`; Task 2 threads the aura-cli caller and runs the workspace gates. Keeps a windows.is_empty() guard in param_stability to preserve the documented empty-on-no-windows contract (C1).
refs #75
Four tasks for the behaviour-preserving carrier swap: (1) add the
branch-free AnyColumn::push_cell + round-trip test (additive); (2) the
atomic lib-code flip (Node::eval -> Option<&[Cell]>, 8 aura-std nodes,
recorder, harness forward loop) gated by a lib-only build; (3) the
cfg(test) migration (fixtures + eval-output assertions per the spec's
three-role rule) gated by the full four-gate run; (4) the C7/C8 ledger
realization note.
refs #74
Three tasks for spec 0046. T1: zip_params (aura-core), RED-first. T2:
GridSpace retains its ParamSpec list + SweepFamily carries it + named_params
(aura-engine), RED-first, with the aura-registry optimize-test SweepFamily
literal threaded in the same task. T3: sim_optimal_manifest typed-Scalar
migration + all eight call sites (aura-cli), behaviour-preserving. Each
signature/field change threads every one of its sites within its own task,
before that task's workspace compile gate.
refs #57
Decompose spec 0045 into two iterations. Iteration 1 (engine + registry
core): Source::bounds() + window_of, M1FieldSource::bounds(), and the
aura-registry lineage module (FamilyKind / FamilyRunRecord / Family,
group_families, next_family_id, the three *_member_reports extractors,
Registry::append_family / load_family_members) with round-trip and
per-name-counter tests. Iteration 2 (CLI surface): aura mc, family-aware
aura runs (families / family [rank]), sweep/walkforward family persistence
via append_family with --name, and the window_of migration of the
manifest-window scans.
refs #70
Bite-sized, placeholder-free plan for the walk-forward axis, in three tasks:
(1) extract MetricStats::from_values from McAggregate::from_draws + serde derive
(behaviour-preserving, the 7 mc tests guard); (2) the walkforward module —
WindowRoller (bounds-only iterator), walk_forward over the shared run_indexed
core, continuous OOS stitch (empty segment -> +0.0), on-demand param_stability,
+ crate exports + module-header doc-lag fix; (3) the aura walkforward CLI demo
bridging engine+registry via optimize, with serde_json for the summary line.
RED-first tests 1-11 (incl. 7b empty-segment stitch) per the spec.
refs #69
Three tasks: (1) extract the disjoint-parallel core out of sweep_with_threads
into a shared `pub(crate) run_indexed<T>` (behaviour-preserving; the three
pre-existing sweep tests are the green guard), (2) add the `mc.rs` module
(McDraw/McFamily/McAggregate/MetricStats, type-7 `quantile`,
`McAggregate::from_draws`, `monte_carlo`/`monte_carlo_with_threads` driving
run_indexed) with 7 RED tests, (3) wire `mod mc;` + the five public exports into
lib.rs. RED-first; module-declaration ordering keeps mc.rs's tests dark until the
final wire-up task.
refs #68
Two tasks: (1) aura-engine SplitMix64 PRNG + pub SyntheticSpec::source(seed) ->
impl Source beside VecSource, with producer RED tests; (2) aura-cli
sim_optimal_manifest gains a seed param (four callers pass 0), plus a test-only
run_sample_seeded + SeededTrace and three e2e RED tests pinning the #66
acceptance. RED-first throughout.
refs #66
Decomposes the boss-signed spec into four tasks: (1) the `Source` trait +
`VecSource` adapter in aura-engine; (2) the atomic `Harness::run` re-type to
`Vec<Box<dyn Source>>` with all 53 call sites threaded behaviour-preserving;
(3) the streaming `M1FieldSource` over a data-server window; (4) a gated
streaming e2e + the measured residency predicate.
refs #71
"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.
Implement-time discovery: the new check (and the existing edge/role checks) compute
signature() on every interior node before the recursion validates that node's
interior. For a structurally-invalid composite (an out-of-range OutField or role
target), derive_signature indexed unguarded and PANICKED — exposed by
output_port_out_of_range_rejected the moment its covering root role forces
c.signature(). Added Task 1 Step 2b: make derive_signature and interior_slot_kind
bounds-total (a placeholder kind for an invalid index; the real fault is still
reported by validate_wiring's guarded OutputPortOutOfRange / BadInteriorIndex). Fix
verified empirically before re-dispatch. Not a design change to the check itself.
refs #65
Seven-task plan for the wiring-totality check (parent spec
docs/specs/0040-wiring-totality-check.md, 07b1ae1 + blast-radius correction
69b16f7): add the two CompileError variants + check_ports_connected + its
validate_wiring call site (T1); re-wire the three under-wired negative tests with a
covering root role (T2); fully wire the param-order nesting test (T3); add five
raw-surface tests — unwired, double-wire via edge+role and edge+edge, nested,
open-role boundary (T4); add the builder-surface forgotten-leg test (T5); land the
C8 ledger realization note (T6); full-suite + clippy gate (T7).
The blast radius (T1's expected-4-failures gate, T2/T3's fixes) was enumerated
empirically by a throwaway probe, not a hand-trace, after the hand-trace under-counted
it by one (param_space_mirrors_..._under_nesting).
refs #65
Task-by-task plan for the typed-handle GraphBuilder: the From<Composite> lift,

Six bite-sized tasks for spec 0037: aura-core records a BoundParam (original slot
position) in bind + a bound_params() accessor; aura-engine emits a conditional
"bound" field via scalar_str; graph-viewer.js merges free+bound params into slot
order and renders the bound slot dimmed as name=value; re-capture the sample-model
fixture; a new headless render guard (trailing + middle bind); full-workspace gate.

Five tasks for the sample-showcase cycle: (1) the enriched blueprint source —
LinComb import, the `signals` composite (trend = sma_cross, momentum = macd, blend
= LinComb(3) with weights[2] bound), the node-0 swap in sample_blueprint_with_sinks,
the re-pathed sweep_family axes + a showcase_prices warm-up stream; (2) re-path the
two in-crate tests (bootstrap-runs-drains, sweep odometer); (3) re-capture the
sample-model.json render fixture; (4) a new headless depth-2 nesting guard
(viewer_nested_depth.mjs + .rs); (5) the workspace build/test/clippy gate.
refs #62
Task decomposition for PrimitiveBuilder::bind (spec 0034): T1 the method +
aura-core unit tests (Probe node drives positional reconstruction RED→GREEN;
three should_panic), T2 node-vehicle coverage (Sma/LinComb via eval in aura-std),
T3 Composite param_space coverage + construction-layer zero-change guard +
workspace gate. Crate-topology aware: aura-core unit tests use a local Probe,
not Sma/LinComb (no upward dep).
refs #55
Two-task RED→GREEN plan for spec 0033. Task 1 (RED, test-only): flip the engine
canonical-form golden + the CLI sweep golden to the serde array-of-pairs/.0-float
shape, add the to_json_equals_serde_disk_shape pin test — all fail against the
current hand-rolled to_json. Task 2 (GREEN, atomic): promote serde_json dev-dep ->
normal dep, swap to_json's body to serde_json::to_string, delete the now-unused
json_str helper, refresh the method + module-header doc comments — one build+clippy
gate flips every Task-1 assertion green. graph_model.rs:30 + INDEX.md:729 stale
cross-refs deferred to cycle-close audit.
refs #54
Implementation plan for spec 0031 (#56). Three tasks:
1. aura-core PrimitiveBuilder instance-name mechanism (.named()/node_name(),
default = lowercased type label) — additive.
2. The engine mechanism + the full compile-coupled migration, as one task by
necessity: collect_params node segment, signature_of + fan-in re-keyed onto
the node name, ParamAlias / Composite.params / the Composite::new 5th arg /
aliases_on / check_alias_indices removed, every in-workspace Composite::new
caller and ParamAlias reference migrated, the mirror / top_level (inverted) /
signature / CLI-golden assertions updated — all under one cargo build/test
--workspace gate that enumerates migration completeness.
3. Ledger C9 + C23 amendments.
plan-recon (DONE_WITH_CONCERNS) surfaced two sites the brief missed, both now in
the plan: the sweep-golden twin crates/aura-cli/tests/cli_run.rs:214 (lockstep
with main.rs), and the model_to_json goldens — resolved as OUT of scope (the JSON
model emits the type label + factory param names, both node-name-independent, so
sample-model.json and the graph_model.rs golden stay byte-identical; the fixtures
migrate structurally only). signature_of stays -> String, re-keyed onto the node
name. fieldtests/ are frozen non-workspace records, out of scope.

Iteration-2 plan for spec 0030 (the sweep side): two tasks.
- Task 1 (aura-engine): resolve_axes (shares resolve's name->slot mapping; adds the
EmptyAxis check and a per-element axis kind-check, a superset of GridSpace::new so
the downstream .expect() is infallible), Composite::axis / SweepBinder /
SweepBinder::sweep, the SweepBinder re-export, and the engine tests (round-trip,
EmptyAxis, MissingKnob, per-element KindMismatch on a mixed axis, a builder
no-panic wrong-kind test, and a GridSpace .points() parity test). RED-first via a
todo!() resolve_axes stub. EmptyAxis is now constructed (was defined in iter 1).
- Task 2 (aura-cli): convert sweep_family() grid construction to .axis(...).sweep(...)
(keeping the per-point closure and the local `space` it reads for manifest params);
drop the now-orphaned GridSpace import (the clippy -D warnings trap this iteration).
The sweep JSON param goldens (main.rs + tests/cli_run.rs) are name/value/order-
preserving and stay green unchanged. Engine core untouched (C1/C12/C19/C23).

Iteration-1 plan for spec 0030 (the single-run side): two tasks.
- Task 1 (aura-engine): BindError vocabulary, the shared `resolve` core
(two-phase total error order), Composite::with / Binder / Binder::bootstrap,
the lib.rs re-export, and the engine tests (resolve round-trip, one per
single-run BindError variant, two precedence tests, the C1 named≡positional
equivalence test). RED-first via a todo!() resolve stub, GREEN on impl.
- Task 2 (aura-cli): convert the sample single-run test to .with(...).bootstrap()
using the exact param_space() names (sma_cross.fast/sma_cross.slow/scale).
The full BindError enum (incl. EmptyAxis) is defined now and re-exported, so the
unconstructed sweep-only variant is reachable API (not dead_code) — EmptyAxis is
constructed in iteration 2. Engine core untouched (C1/C12/C19/C23).

Final iteration of cycle D: aura sweep persists each point's RunReport to
runs/runs.jsonl; aura runs list prints every stored record; aura runs rank
<metric> prints them best-first. sweep_report splits into a production
sweep_family() + a #[cfg(test)] renderer; process goldens run in a temp cwd so
persistence never dirties the repo; /runs/ is git-ignored.
refs #33
Iteration 2 of cycle D: SweepPoint carries a full RunReport (closure bound ->
RunReport), all engine + CLI callers rethreaded in lockstep so the workspace
returns green; the hand-rolled sweep_point_to_json retired (each point prints
via RunReport::to_json); new aura-registry crate (open/append/load/rank_by +
RegistryError), built and unit-tested but not yet CLI-wired. The aura sweep
goldens pin the per-point manifest params, not the volatile git-HEAD commit.
refs #33
Iteration 1 of cycle D: amend C16 (blanket zero-dep -> per-case policy) in the
ledger + the five source comments asserting the struck framing; add serde/
serde_json workspace deps; derive Serialize/Deserialize on Timestamp and the
RunMetrics/RunManifest/RunReport report types, with serde_json round-trip tests.
No CLI change, no aura-registry crate, no SweepPoint change (those are iter 2/3).
