claude 5c2ac982bc refactor: extract the member-run recipe into library crates (#295 part 1)
The shell no longer defines what an aura backtest is. Tasks 1-9 of the
shell-boundary cycle — structural extraction, behaviour byte-identical:

- aura-runner (new; the C28 assembly position): input binding (the C26
  module, moved whole), the C1-load-bearing param<->config translators,
  harness assembly (wrap_r / run_signal_r / run_blueprint_member and the
  probe/reopen cluster), axis + risk-regime conventions (bind_axes et
  al.), the campaign family builders + MC guards, reproduce
  (process::exit -> RunnerError, shell remaps to identical bytes), the
  measurement-run orchestration, project loading (Env / cdylib load /
  charter / staleness, moved whole), the coverage gap-walk (deduplicated
  onto interior_gap_months), and DefaultMemberRunner — the public
  implementation of aura_campaign::MemberRunner (ex CliMemberRunner).
  The MemberRunner trait stays in aura-campaign; the column still
  imports no harness/data-binding machinery.
- aura-measurement (new; seeds C28 rung 3): the IcMetrics/IcKey
  vocabulary + information_coefficient, verbatim incl. serde derives
  (#294 duplicate-timestamp semantics move as-is, unresolved).
- aura-backtest: the pure per-run scaffold (point_from_params,
  wf_ms_sizes / fit_wf_ms_sizes, intersect_shared_window).
- shell residue: main.rs / campaign_run.rs keep argv/dispatch,
  argv->document translation, and presentation only;
  walkforward_summary_json_from_reports now calls the public
  aura_engine::param_stability instead of its inline twin.
- worked example (crates/aura-runner/examples/world_member_run.rs): a
  World program runs a member backtest through the library alone.

Held quality findings, adjudicated: the plan's literal pub-visibility
list for binding.rs kept (cosmetic); ~20 refusal sites inside
aura-runner (family/member/measure/translate) still process::exit —
behaviour-identical today, conversion to RunnerError is filed forward
(refs #297); rustfmt line-width drift on re-pathed call sites left for
a repo-wide fmt decision.

Verification: cargo test --workspace green (1471 passed, 0 failed);
cargo clippy --workspace --all-targets -D warnings clean. Byte-identity
is pinned by the untouched shell E2E suites (cli_run, measure_ic,
run_measurement, research_docs, run_refuses_unrunnable_blueprint,
tap_recording — zero assertion edits).

Remaining in this cycle: full-workspace c28_layering + shell-content
check, ledger amendments (C28 assembly position, C25/C14 control-surface
consequence, C26 realization note).

claude a9d36ddd70 feat: measurement's first deflatable metric — the Information Coefficient
Give a measurement run a standalone post-run quality score: the Information
Coefficient (IC), corr(signal_t, forward_return_{t+h}), with a permutation
null model. Before this a measurement run persisted only tap names and series
(MeasurementReport) — inspectable but not rankable or deflatable. IC is the
first metric measurement supplies: the tap-to-scalar reduction the C28
process-column / metric-interface seam anticipates ("a named metric vocabulary
supplied by measurement and backtest instead of baked in R-only").

Surface: `aura measure ic <run> --signal <tap> --price <tap> [--horizon]
[--permutations] [--seed]`. It reads the run's two recorded tap traces, builds
the forward-return series offline over the recorded price spine, aligns
signal -> return by exact timestamp, computes the IC, and prints it with a
one-sided permutation-null overfit probability (Laplace-smoothed, mirroring the
R deflation arm's formula in optimize_deflated).

Placement follows the C28 ladder: the generic pieces — pearson_corr and a
Fisher-Yates permute over SplitMix64 — land in aura-analysis (the domain-free
statistics foundation, beside resample_block); the IC semantics (forward-return
horizon, the offline join) and the CLI verb land in aura-cli (the shell). The
run path (run_measurement), MeasurementReport, the trace store, and the registry
metric vocabulary are untouched — existing `aura run` output stays byte-identical
(the C18 golden run_prints_json_and_exits_zero stays green).

Causality (C2): the forward-return read close_{t+h} is over a completed run's
recorded trace, not an in-graph node. A look-ahead signal is structurally
impossible in a causal run, so the engineered-vs-noise acceptance property is
unit-tested over hand-built offline series (perfect signal -> IC ~= 1, p < 0.05;
a varying but exactly-uncorrelated signal -> IC = 0, not significant;
constant/degenerate -> the (0.0, 1.0) floor), while the E2E validates the CLI
wiring, report well-formedness, determinism, and the error paths over a real run.

This lands the second, structurally distinct null-model computation (permutation,
beside the moving-block bootstrap behind R). That makes the deferred registry
deflation-vocabulary abstraction (#147 item 2) demand-driven rather than
speculative — the next cycle.

Verified: cargo test --workspace green (incl. the new aura-analysis unit tests,
the aura-cli ic_* unit tests, and the measure_ic E2E); cargo clippy --workspace
--all-targets -D warnings clean; the C18 byte-identity golden unchanged.

claude b39fd63396 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.

claude c31e946bb7 test(cli): synthetic per-test M1 archive — no-window generalize tests go hostless
The two generalize E2E tests whose property is no-window span
resolution (shared-window fallback, intersection semantics) no longer
stream the 6.6 GB host archive: fresh_project_with_data() generates a
deterministic two-symbol M1 archive (SYMA 2024-01..08, SYMB 2024-03..06
strictly inside it, so the intersection differs from symbols[0]'s
window on both bounds) in the exact zip/48-byte-record format
data-server reads, plus geometry sidecars, under the per-test project's
paths.data. Both tests drop their local_data_present gates — they now
run on any host, data mount or not.

~35s and ~50s become 0.74s and 1.14s; the full cli_run binary lands at
~25s (211s at the branch base). Full workspace suite: 247s -> 45.7s.

Brummel aeb0366aed feat(cli): aura campaign run — the executor verb over the MemberRunner driver (0107 tasks 8-9)
campaign_run.rs: target resolution (file is register-then-run sugar;
bare 64-hex is the canonical id — #198 decision 1), project gate before
any store write, zero-fault referential gate, process fetch + v1
preflight, then aura_campaign::execute with the CLI MemberRunner over
the shipped loaded-blueprint convention: per-member blueprint reload,
reduce-mode wrap, unique suffix-join of raw campaign axis names onto
the wrapped param_space, windowed real data via the shipped ms->ns
source seam (absent archive/zero-bar windows -> NoData). Emission:
family_table / selection_report lines gated on the doc's emit list
(names debug_asserted against emit_vocabulary), the campaign_run
record line always, persist_taps deferred LOUDLY on stderr before
execution (F7 lesson), zero-survivor cells noted on stderr with exit 0.
exec_fault_prose/member_fault_prose keep the Debug-free house seam.

Seam tests: 8 campaign_run_* e2e tests incl. outside-project, bogus
target, unknown id, v1-boundary (mc process registers fine, run
refuses), persist_taps ordering, and the gated real-data
sweep->gate->walkforward e2e — which ran its full assert path on this
host (local GER40 2024-09 archive) rather than the data-less skip.
Also: exec.rs campaign-id guard tightened to lowercase hex, matching
is_content_id and the store's self-keyed form (review nit).

Gates: workspace 975/0, clippy -D warnings clean.

Brummel ef3bec5844 feat(research): 0106 tasks 1-9 — document layer, content-id move, stores + referential tier
The aura-research leaf crate: ProcessDoc/CampaignDoc with strict parsing
(hand-rolled StageBlock deserializer — deny_unknown_fields does not compose
with internally-tagged enums; Axis declares its ScalarKind once with bare
values, per the #189 user veto), canonical form + content_id_of (the
SHA-256 primitive moved from aura-cli, which now delegates — the id pin set
incl. the independent sweep-store recompute stayed green untouched),
intrinsic validation for both document types (P1 constraints structural),
and the introspection contract (schema tables single-source parse
strictness AND vocabulary/describe/open-slots — the Blockly litmus made
checkable). aura-registry: content-addressed processes/ + campaigns/
stores on the blueprint-store pattern (Ok(None) treat-as-empty) and the
referential tier (validate_campaign_refs: process/strategy refs incl.
identity-scan, axis-name + declared-kind checks against param_space).

Plan deviations, verified by hand and folded back into the plan file:
- Task 9's fixture could not use aura-composites as planned: every shipped
  composite with an open param routes through LinComb, which the zero-arg
  std_vocabulary roster deliberately excludes, so none round-trips through
  blueprint_from_json with the by-type-name resolver. The test hand-builds
  a minimal Bias composite instead (generic over param_space, as planned);
  the unused pro-forma aura-composites dev-dep from the repair pass is
  dropped. This is why the loop reported task 9 BLOCKED
  (review-loop-exhausted on the literal code block); the tree itself is
  complete and green.
- A plan-verbatim test assertion false-matched ("deflate" as substring of
  "deflated-positive"); tightened to the JSON key.
- OpenSlot doc comment backticked (rustdoc read strategies[0] as a link;
  doc gate back to 0 warnings).

Verification: cargo test --workspace 898/0; clippy -D warnings clean;
cargo doc --no-deps 0 warnings. Tasks 10-12 (CLI verb families, final
gates) follow.

Brummel 4928e289f7 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.

Brummel 4de6d5cbad rename: retire the stage1-* family for the r-family (r-sma / r-breakout / r-meanrev)
The stage1 ordinal has been dead vocabulary since the C10 reframe dropped
the two-stage research model: a 1 structurally implies a 2 that no longer
exists. The family is renamed by its live discriminator - the R yardstick -
with members named by their signal, uniform with their signal-named
siblings (sma, macd, momentum):

- selectors: stage1-r -> r-sma, stage1-breakout -> r-breakout,
  stage1-meanrev -> r-meanrev (old tokens are usage errors, exit 2 - no
  silent alias)
- identifiers: Strategy::RSma/RBreakout/RMeanRev, HarnessKind::RSma,
  r_sma_*/r_breakout_*/r_meanrev_*, wrap_r, run_signal_r, RGrid, R_SMA_*
- persisted identity: the sma_signal composite (param prefix
  sma_signal.fast.length / .slow.length; fixtures regenerated; content-ids
  shift - no test pins a literal hash, the registry parses no record names)
- e2e test files git-mv'd to r_sma_e2e / r_breakout_e2e / r_meanrev_e2e
- dead Stage-1/Stage-2 prose reworded to post-C10 vocabulary across
  rustdoc, Cargo.tomls, ledger live lines, and the glossary (historical
  entries stay; fieldtests corpus untouched)
- CLAUDE.md invariant 7 rewritten to record the ratified C10 reframe
  faithfully (the token-swap alone would have laundered the retired
  gated-currency/realistic-broker design into unmarked live prose); the
  unbacked account-mode clause dropped

Verification: cargo build/test --workspace green (51 targets), clippy
-D warnings clean, doc build clean, acceptance grep gate leaves exactly
the one resampling-stage false positive (harness.rs), smoke: --harness
r-sma runs, --harness stage1-r exits 2 with the new usage line.

+ implementation-phase comments).

Brummel 366170aeab feat(0098): CLI clap migration (iteration 1) — scoped help, --version, GNU flags
Replace the hand-rolled aura-cli argv parser with a clap derive parser.
Delivers, all from one declarative source:
- scoped `aura <sub> --help` (stdout, exit 0) — each subcommand's own Options
  section; retires the #131 uniform-global-blob help
- `--version` / `-V` → `aura 0.1.0` (stdout, exit 0)
- GNU `--flag=value`, the `--` end-of-options terminator, and long-option
  abbreviation (`--harn` → `--harness`)

Architecture: one root Cli/Command enum, one `*Cmd` struct per subcommand. The
four dual-grammar subcommands (run/sweep/walkforward/mc) map the loaded-blueprint
branch as an optional `[blueprint]` positional + a post-parse `is_file()`
dispatch on a single-sourced predicate; each built-in handler re-asserts a
stray-positional guard (refuse-don't-guess) so clap's optional positional cannot
silently swallow a typo (pinned by two new E2E tests). The execution layer
(run_*/emit_*/runs_*/reproduce_*) is untouched — only arg-plumbing changes, via
thin `*_from` adapters reusing the existing value helpers.

Exit codes behaviour-preserved: clap parse errors exit 2 (matching the old
usage-error=2); domain refusals stay exit 2; reproduce-diverged stays exit 1.
The exit-code split (2=usage / 1=runtime) is iteration 2. clap is admitted under
the C16 per-case review (research-side CLI, invariant 8 untouched — a dev-loop
compile tax, not a frozen-artifact tax).

Forced plan corrections (implementer; verified against the diff):
- Step 6's deletion of the `parse_*_args` fns orphaned ~34 grammar unit tests
  that called them; those were deleted and that grammar coverage moved to the
  renegotiated cli_run.rs E2E pins (`parse_select` kept + retested).
- run_malformed_cost_value_...: a bad cost value is now a clap value-parse error
  (no "Usage:" line); renegotiated to pin exit 2 + empty stdout + the flag name
  "--cost-per-trade"; the units note stays pinned via `run --help`.
- `allow_hyphen_values` on the three cost flags so `--cost-per-trade -0.5`
  reaches the non-negativity guard (else clap rejects -0.5 as an unknown option).
- Deleted the now-dead `RealWindowGrammar` (clippy -D warnings).

Orchestrator additions after the loop:
- Enabled long-option abbreviation (`infer_long_args` on the root — one
  attribute, it propagates to subcommands) + a test, closing spec acceptance
  criterion 4 which the plan's RED tests did not cover. Decided to deliver
  rather than amend the spec: the two ratified decisions conflict on this
  low-tier item — Fork B (GNU compliance, getopt_long abbreviates) vs F5
  (LLM/automation-first, human-only niceties deprioritized) — and the cost
  tiebreaker (one attribute, not per-struct work) resolves to deliver.

Carry-on debt (not this iteration): the error-message "Usage:"/"usage:"/bare
casing is now mixed (clap's capitalized "Usage:" beside preserved lowercase aura
messages); a deliberate quality-hold since the casings are pinned by
renegotiated/preserved tests. Cosmetic; a candidate for the iteration-2
exit-code-split cleanup.

Verified green (orchestrator, this session): cargo build --workspace, cargo
clippy --workspace --all-targets -- -D warnings, and cargo test --workspace all
clean (0 failed across every test binary, including the renegotiated cli_run
pins and the new --version / scoped-help / GNU-flag / dual-grammar tests).

Brummel ff4a1b3d4a 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.

Brummel 1088320571 fix: terminate cleanly on a broken stdout pipe across all family-emitting commands
GREEN for the broken-pipe RED test (c750b9f). Rust's runtime sets SIGPIPE to
SIG_IGN at startup, so a println! to a closed stdout pipe returned EPIPE and
panicked ("failed printing to stdout: Broken pipe", exit 101). Restore the
default SIGPIPE disposition once at the top of main() (cfg(unix), via
libc::signal) so a closed pipe terminates the process cleanly on SIGPIPE
(signal 13 / exit 141 — the conventional Unix CLI outcome, e.g. `yes | head`)
instead of panicking. One process-level reset covers every family-emitting
subcommand (sweep / mc / walkforward / runs family / generalize); the print
sites are untouched (minimal fix).

libc added as a direct aura-cli dependency — already transitive in Cargo.lock,
the standard vetted crate for signal disposition, admitted under the per-case
dependency policy.

Verified by the orchestrator: the broken-pipe test passes 6/6; `aura sweep | head`
exits 141 with no panic in stderr; cargo test --workspace green (0 failed);
clippy --workspace --all-targets -D warnings clean.

Brummel 1a6eafa056 refactor(composites): extract Stage-1 composite-builders into their own crate
Dissolve the aura-engine -> aura-std dependency by moving the vol_stop /
risk_executor composite-builders out of aura-engine into a new aura-composites
crate. This restores the engine's domain-free layering, which the
composites-in-engine placement (cycle 0065) had inverted.

Why: the engine routes type-erased Scalar records and never names a concrete
node -- summarize_r reads the PositionManagement record positionally, by column
index, without linking aura-std (which is exactly why aura-std was a dev-only
dependency before 0065). Parking the node-naming composite-builders inside
aura-engine forced the engine's production code to reference the node library
for the first time (aura-engine -> aura-std), an upside-down layering: the
engine is the foundation the node library builds upon, not the reverse.

The clean home is a dedicated crate that depends on BOTH the engine's
GraphBuilder and the std nodes, leaving each lower crate untouched:

    aura-composites -> { aura-engine, aura-std } -> aura-core   (acyclic)
    aura-engine     -> aura-core only            (domain-free again)
    aura-std        -> aura-core only            (lean node library)

aura-std reverts to a [dev-dependency] of aura-engine (the engine's own E2E
tests -- stage1_r_e2e, random_sweep_e2e, ger40_breakout -- still drive real
std nodes through a bootstrapped Harness; that test-only edge creates no cycle).

Moved with history (git mv):
- crates/aura-engine/src/composites.rs           -> crates/aura-composites/src/lib.rs
- crates/aura-engine/tests/risk_executor.rs      -> crates/aura-composites/tests/
- crates/aura-engine/tests/vol_stop_composite.rs -> crates/aura-composites/tests/

Consumers rewired: aura-cli imports risk_executor / StopRule from aura_composites;
the moved tests import the builders from the crate under test. The intra-doc link
to RollMode and the module rationale doc are updated for the new home.

Behaviour-preserving: workspace build clean; clippy --all-targets -D warnings
clean; full suite 513 passed / 0 failed, identical to baseline (the two moved
test files run unchanged under aura-composites); cargo doc --no-deps clean (no
broken intra-doc links).

Brummel 15ee6d5f4f feat(trace-charts): serve persisted traces as a web chart (iter 2)
Iteration 2 (serve half) of the visual face — spec 0056 / plan 0056:
read a persisted run's traces and serve them as a self-contained uPlot
HTML chart. Completes the goal "tap data from a graph, serve it as a
chart in the browser".

- chart-viewer.js (first-party): a pure buildCharts(traces, mode) that
  maps the injected window.AURA_TRACES to uPlot configs (no DOM) — overlay
  = one plot, every series on its own y-scale over the shared xs; panels =
  one plot per series, all on the same timestamp x. A browser-only mount()
  instantiates the vendored global uPlot. Guarded by a node .mjs DOM test
  (+ a sparse/gaps variant) shelling out exactly like viewer_dot.rs.
- render_chart_html + ChartMode/ChartData/Series (aura-cli/render.rs):
  mirrors render_html — self-contained page, uPlot (1.6.32, vendored
  d534f10) + chart-viewer.js inlined via include_str!, data injected as
  window.AURA_TRACES.
- emit_chart + build_chart_data (aura-cli/main.rs): the spec-§6 3-step
  union-spine alignment — xs = sorted-dedup union of every tap's ts; a
  synthetic empty-payload spine + ALL taps as symmetric join_on_ts sides
  (no tap privileged, no point dropped); flatten each (tap,column) to a
  Series of Option<f64>. New arms `aura chart <name> [--panels]`; a
  missing run is stderr + exit 2 (TraceStoreError::NotFound), never a
  panic. USAGE advertises the verb in lockstep.

Verified by the orchestrator: `cargo test --workspace` green (incl. the
node guards, render_chart_html, and the chart e2e); `cargo clippy
--workspace --all-targets -D warnings` exit 0; and a real end-to-end —
`aura run --trace demo && aura chart demo` emits a 57KB self-contained
page (doctype + inlined uPlot + AURA_TRACES carrying the equity/exposure
series), `--panels` reflects the panels mode, `aura chart nope` exits 2.
Implementer deviation folded in (compiler-prescribed): serde added to
aura-cli/Cargo.toml for the Series derive (Cargo.lock updated).

Brummel 4764656062 feat(aura-engine): walk-forward family — WindowRoller + walk_forward (C12 axis 3)
The third C12 orchestration axis: walk-forward varies the data window. A
WindowRoller is a pure iterator of WindowBounds { is, oos } — bounds only, never
tick data (#71 firewall). walk_forward runs a caller closure per split disjointly
over the shared run_indexed core (C1), and stitches the OOS pip-equity segments
into one continuous curve (each segment offset by the running sum of prior
segments' finals; an empty segment contributes 0.0, mirroring summarize). C2
no-look-ahead is structural: the roller only ever emits oos.0 == is.1 + 1, pinned
by a zero-tick bounds test. The in-sample optimize (axis 2) is closure-supplied,
not called by the engine: aura-engine has no aura-registry dependency (C9), and
C12 forbids baking search policy into the primitive — the CLI bridges both crates.

Param-stability is on-demand, not stored (the R2 decision, recorded with
provenance on #69): WalkForwardResult stores only the raw per-window outcomes +
the stitched curve, and param_stability(&result) -> Vec<MetricStats> is a public
reduction over the retained per-window chosen params. A stored summary would be
recomputable from the windows (redundant) and would force one statistic canonical
when "stability" admits several; this mirrors SweepFamily (raw points + on-demand
optimize), not McFamily (stored aggregate). MetricStats::from_values is extracted
from McAggregate::from_draws (behaviour-preserving — the 7 mc tests stay green)
and gains serde so the CLI summary renders it and #70 lineage can persist it.

`aura walkforward` runs a built-in rolling walk-forward over a synthetic windowed
source: per window it sweeps the built-in grid in-sample, optimizes by total_pips,
runs the chosen params out-of-sample, persists each OOS RunReport (C18), and prints
a stitched summary line.

Two plan deviations, both compiler-forced and consistent with siblings: added
#[derive(Debug)] to WindowRoller (the RED tests' unwrap_err needs Ok: Debug; the
sibling types already derive Debug); removed a now-redundant test-module
SyntheticSpec import after Step 2 hoisted it to the top-level use.

Verification: cargo test --workspace green (aura-engine 152 incl. walkforward 9 +
mc 9, aura-cli 14); clippy --workspace --all-targets -D warnings exit 0; cargo doc
--workspace --no-deps clean.

Brummel 0ce843bada feat(aura-cli): aura run --real <SYMBOL> backtests the sample on real M1 bars
The first real-data backtest from the CLI: `aura run --real <SYMBOL>
[--from <ms>] [--to <ms>]` runs the existing built-in sample signal-quality
harness over real M1 *close* bars instead of synthetic prices, printing the
same RunReport JSON as `aura run`. Bars are streamed lazily through
aura_ingest::M1FieldSource (a Box<dyn Source>) — dogfooding the #71 Source
seam, O(one chunk) resident, never eager. aura-ingest + data-server enter
aura-cli's deps (data-server git line mirrored from aura-ingest).

M1 only this cycle, deliberately. The TickSource is deferred: raw ticks are
the wrong input for the bar-semantic SMA sample (an SMA over ticks is
microstructure noise until a resampler node exists, C2), and tick's real
driver is the realistic broker's bid/ask execution (C10) — it should arrive
with that consumer, not speculatively here. Tick data is also local to only
EURUSD/XAUUSD/GER40, whereas M1 covers the test symbol AAPL.US.

Shape: run_sample_real builds sample_harness(), guards has_symbol /
M1FieldSource::open (unknown symbol or empty window -> 'aura: no local data'
+ exit 2, never a panic), and reuses sim_optimal_manifest + the run_sample
fold. parse_real_args is a pure, unit-tested grammar (mandatory symbol, then
--from/--to in any order; bad/missing/duplicate flag -> Err). Data path is
data_server::DEFAULT_DATA_PATH (no --data-path flag this cycle).

Known simplification: the manifest window is derived by draining a *separate*
single-pass probe source for first/last ts, so an unbounded window streams
the archive twice (once to bound, once to run). Acceptable and O(1)-resident
for now; a future Harness::run could surface the first/last cycle ts to drop
the probe pass.

Verified: cargo build/test/clippy --workspace all green; the gated
run_sample_real_streams_real_close_bars_deterministically RAN (not skipped)
over AAPL.US 2006-08; manual CLI smoke of the success + two error paths.

Brummel 5bded0ca83 feat(aura-cli): aura runs registry — persist on sweep, list + rank (cycle D / iter 3)
Final iteration of the run-registry cycle (#33): the read surface that makes a
sweep family — and runs across separate invocations — comparable over time
(C18's "compare experiments over time", which has no home in git or Gitea).

- `aura sweep` now persists each point's RunReport to runs/runs.jsonl (append-
  only, one serde_json line per run) in addition to printing it.
- `aura runs list` prints every stored record, in store order.
- `aura runs rank <metric>` prints the stored runs best-first by the metric
  (total_pips desc; max_drawdown / exposure_sign_flips asc); an unknown metric
  is a usage error (exit 2), like every other aura arg error.

sweep_report splits into a production sweep_family() (the pure run) and a
#[cfg(test)] renderer kept for the in-bin goldens; the dispatch gains run_sweep
/ runs_list / runs_rank over default_registry() (runs/runs.jsonl under cwd).
Process goldens run the binary in a temp cwd so persistence never dirties the
repo; /runs/ is git-ignored as a backstop.

Verified end-to-end: two `aura sweep` invocations accumulate 8 records;
`aura runs list` shows all 8; `aura runs rank total_pips` orders them best-first;
`aura runs rank bogus` exits 2 with the known-metrics hint. cargo test
--workspace green (cli_run 11, registry 5, engine 93, …); clippy
--workspace --all-targets -D warnings clean; no stray runs/ in the work tree.

Brummel 66dff88528 feat(aura-cli): render the graph as a self-contained WASM-Graphviz viewer; retire ascii-dag
Iteration 2 of cycle 0026 (graph render redesign). `aura graph` no longer emits
ASCII: it now prints one self-contained `.html` to stdout — the ported prototype
pin-graph viewer (drill / inline-expand / styled tooltips / breadcrumb) driven by
the deterministic model serializer that shipped in iteration 1, with layout and
SVG done in-browser by Graphviz compiled to WebAssembly. Closes the redesign
opened by spec 0026; unblocked by cycle 0027 (input ports are now named, so the
viewer labels every input pin from the model's real names instead of inventing
"a"/"b").

What ships:
- crates/aura-cli/assets/: the ported graph-viewer.js (prototype genDot/chrome
  verbatim + a normalizeModel adapter mapping aura's real model tuple shape —
  ins = [kind, firing, name], index node keys, `comp` refs, `src_<role>` — into
  the viewer's native shape), plus the vendored Graphviz-WASM (@viz-js/viz@3.7.0)
  and svg-pan-zoom@3.6.1 blobs and a refresh-assets.sh provenance script.
- crates/aura-cli/src/render.rs: render_html(&Composite) -> String, a read-only
  (C9) assembly — model_to_json + include_str! of the inlined assets, no eval,
  no build, no serde (C14). The `["graph"]` arm calls it.
- Retired: the ascii-dag adapter (graph.rs), the `ascii-dag` dependency, the
  `--compiled`/`--macd` graph flag plumbing, render_compiled, the color/terminal
  plumbing, and the 12 ascii-dag-asserting tests + the now-orphaned helpers.
  The cli_run integration test now pins the HTML page envelope.
- crates/aura-core/src/node.rs: the two last ascii-dag prose justifications
  re-grounded (single-line label rule kept, re-justified generically; the
  param-generic rule re-justified on C23, not on a renderer limitation).
- docs/design/INDEX.md: the cycle-0026 C9 realization note (both iterations).

Vendoring decision (spec deferred it to the plan): the WASM/JS blobs are checked
in, not fetched at build time. include_str! needs them at compile time, and a
build-time unpkg fetch would make the build non-hermetic/non-offline and let the
shipped artifact drift with the registry — against C1 (determinism) and C8
(frozen artifacts). ~1.4 MB is the price of a hermetic, frozen render asset.

Three adaptations beyond the plan, each verified: (1) render.rs imports
`aura_engine::Composite` (the path model_to_json takes), not aura_core; (2)
macd_blueprint is now test-only — removing the `--macd` arm left it used solely
by the param-space test, so it took `#[cfg(test)]` rather than removal or an
`#[allow]` suppression (the production `aura run --macd` path is intact, verified
emitting JSON); (3) the `grep ascii-dag` over crates/ matches only the new
contract test, which names the term deliberately to document the retirement — no
stale justification prose remains.

Invariants held (verified independently, not on agent report): C9 (render path
read-only), C10 (viewer is a render asset, no logic/DSL), C4 (four-colour palette
= the four scalar base types), C14 (no serde). The iteration-1 model byte golden
is unchanged and green. cargo build --workspace: 0 errors. cargo test --workspace:
157 passed, 0 failed (incl. the two new HTML tests + the unchanged model_golden).
cargo clippy --workspace --all-targets -- -D warnings: clean. ascii-dag absent
from `cargo tree -p aura-cli`.

Brummel 0a855c3943 feat(aura-cli): aura graph renders a wired graph as an ASCII DAG (#13)
Make a wired graph introspectable so a mis-wiring becomes visible. Two
selectable views, both authored from one built-in sample blueprint:

  aura graph             clustered blueprint view — composites drawn as named
                         ascii-dag cluster boxes (pre-inline, C9)
  aura graph --compiled  flat compilat view — composite boundaries dissolved
                         (C23); the graph the run loop actually runs

The payoff is intrinsic, param-carrying node labels: two SMAs read SMA(2) /
SMA(4), so a swapped fast/slow input reads back differently. This is realized
by a `label()` default method on the core Node trait — a non-load-bearing
render symbol the run loop never reads (wiring is by index), the symbol C23
already reserves citing #13. Recorded as a C8 refinement in the ledger.
Rejected the alternatives in brainstorm: a separate Describe trait (forces a
combined trait-object dance for a label the ledger calls non-load-bearing) and
extrinsic parallel labels (decoupled from the node, so an author can label the
slow SMA "fast" and mask the very bug the render exists to surface).

Mechanism:
- aura-core: Node::label() default method (additive, object-safe, single-line).
- aura-std: per-node overrides — SMA(n)/Exposure(s)/SimBroker(p) carry params;
  Sub/Add/LinComb/Recorder are bare (their identity is not a mis-wiring axis).
- aura-engine: Composite gains an authored `name` (cluster title; dissolves at
  inline) + read-only graph-as-data accessors on Blueprint/Composite. No
  external dependency — the engine stays dependency-pure (C16); ascii-dag lives
  only in aura-cli. The label-free index-wired compilat (C23) is unchanged.
- aura-cli: ascii-dag v0.9.1 + a graph.rs adapter (Vertical mode; labels
  materialized into an owned Vec<String> that outlives the borrow-based Graph).
  `aura run` is untouched (the sample duplication is dedup idea #14).

Tests: a concern-defining test (swapped sample renders != correct), structure
pins (cluster present in blueprint view, absent in compiled view), per-node
label disambiguation, and two frozen byte-goldens of the deterministic render.
The cycle-0012 bit-identical and run-sample non-regression tests stay green.

Verified by the orchestrator (not the agent report): cargo build --workspace
clean; cargo test --workspace all green; cargo clippy --workspace --all-targets
-D warnings clean; both views run live and render as expected.

Brummel 559903a14e feat(aura-cli): aura run — end-to-end sample-harness CLI
The Walking-skeleton milestone's closing seam: a real `aura run` binary that
bootstraps a built-in sample harness, runs it deterministically, and prints the
cycle-0009 metrics+manifest report as canonical JSON to stdout — the headline
C14 "run a sim, emit structured metrics" move, end-to-end, from a binary for the
first time.

Two deliverables:

- aura-std::Recorder — a reusable recording sink node (the glossary *sink* role,
  C8/C22): a pure consumer (output: vec![]) over kinds.len() input columns,
  holding an mpsc::Sender<(Timestamp, Vec<Scalar>)> as its out-of-graph
  destination. mpsc keeps the engine's purity invariant (C7): no Rc/RefCell.
  Supports all four base scalar kinds; returns None until every column is warm.
  Promotes the shape the #[cfg(test)] fixtures already proved into a shipped,
  reusable block (the fixtures stay as historical snapshots; de-dup is a later
  tidy).

- aura-cli `run` subcommand — synthetic_prices / sample_harness / run_sample /
  main. The sample harness (synthetic source → SMA(2)/SMA(4) → Sub → Exposure →
  SimBroker → two Recorder sinks) is authored in plain Rust over the raw
  Harness::bootstrap(nodes, sources, edges) API (C17/C20) — the open
  experiment-builder DSL thread is deliberately not committed this cycle. main
  hand-parses one subcommand: `run` prints run_sample().to_json() (exit 0),
  anything else prints a one-line usage to stderr (exit 2). aura-cli gains
  aura-std + aura-core path deps; the workspace stays zero-(external-)dependency.

The built-in synthetic stream (7 ticks, rises then reverses) yields a non-trivial
demo trace: equity [0,0,0,0,-0.08,-0.17,-0.13] → total_pips -0.13, max_drawdown
0.17, exposure_sign_flips 1. The run_sample unit test pins the integer flip count
exactly and the two f64 metrics within 1e-9 (the real run's float dust is ~7e-15,
confirming the tolerance); determinism is pinned exactly (two runs → identical
JSON). tests/cli_run.rs drives the built binary for the observable exit/stdout
contract.

manifest.commit is filled from option_env!("AURA_COMMIT") (defaults to
"unknown"); real HEAD capture via build.rs is deferred. Non-goals untouched:
experiment-builder DSL, aura new, Aura.toml schema, the data-server source (#7).

One deviation from the plan's verbatim code: a scoped
#[allow(clippy::type_complexity)] on sample_harness (its (Harness, Receiver,
Receiver) return tuple trips the lint under -D warnings) — consistent with the
identical allow on the build_two_sink_harness fixture in aura-engine. Verified
myself: cargo test --workspace (61 green, 0 red), clippy --all-targets
-D warnings (clean), cargo doc -D warnings (clean), and both smoke runs.
