The two fieldtest findings, resolved:
- friction: --parallel-instruments 0 now refuses in domain terms ("must be
a whole number of at least 1 — it bounds how many distinct instruments
are resident in parallel") via a custom clap value-parser, instead of
leaking Rust's NonZeroUsize wording; the zero-bound test pins the prose.
- spec_gap: the authoring guide's exit-code contract now states that a
gate-emptied cell (a std::gate leaving no survivors) is a successful
cell — exit 0 with an informational aura: note and a truncated
realization — and that exit 3 is reserved for cells that could not be
evaluated. Records observed behaviour; no code change.
Gates re-verified: workspace suite green, clippy -D warnings clean.
refs #277
Two pieces of the parallel-cell-loop iteration (spec: parallel-cell-loop),
still sequential — behaviour-identical results, suite green unchanged:
- validate_campaign refuses a campaign document listing the same instrument
twice (DocFault::DuplicateInstrument + CLI prose). A duplicate enumerates
two identical cells and is the one input that could make two cells share a
registry family name; with distinct instruments the per-cell family name
(all four cell axes + stage ordinal) is unique by construction, so the
upcoming parallel appends can never race one name's run-index assignment.
- aura_campaign::execute flattens the 4-nested cell loop into a document-
order-indexed cell list, groups it by instrument ordinal, and walks
sequential chunks of K instrument groups; results land in index-addressed
slots and the ordered outputs (outcomes, realizations, nominee groups) are
rebuilt in document order. K arrives as a new NonZeroUsize parameter
(default DEFAULT_PARALLEL_INSTRUMENTS = 4), exposed as
--parallel-instruments on aura campaign run and threaded through the
run_campaign chain; the dissolved-verb sugar paths pass the default.
The chunk walk is the structural RAM bound for the parallel flip that
follows: no cell of an instrument outside the current chunk can be in
flight at all (chosen over a semaphore gate — blocking inside pool tasks
risks worker starvation; decision log on #277). Verified: workspace suite
green unchanged, clippy -D warnings clean, E2E fixtures pin the CLI prose
and the document-order persistence across K.

Drift review (architect) over ad4249f..HEAD found the cycle drift-clean at the core
and confirmed what holds: C1 preserved (`run()`'s k-way merge / event loop has zero
diff — `run_bound` only reorders the supply via `bind_sources` then delegates to
`run`, byte-identity pinned); the C4 realization and C23 refinement ledger notes are
accurate and tightly scoped (`SourceSpec.role` is read in exactly one place, sourced
only from the lowering — no leak); and all three binding-carrying production run sites
moved to `run_bound` + `key_supply`, every remaining `.run(` being `#[cfg(test)]`. No
regression harness exists, so the architect is the sole drift gate.
One medium drift item fixed:
- FIX: the CLI's `.expect()` on `run_bound` covered Missing/Extra/Unnamed feed but not
`DuplicateFeed`. The blueprint path does not enforce root-role-name uniqueness (only
the construction op-script path does), so a duplicate-role blueprint would reach
`bind_sources`' `DuplicateFeed` and panic behind the `.expect()` instead of refusing.
Closed at the binding boundary: `resolve_binding` now refuses a duplicate input-role
name — a named `aura:`-register refusal on every CLI run path (single run, sweep, and
campaign all resolve the binding upfront), matching its existing price/close-ambiguity
refusal. The `.expect()` invariant is now genuinely true on all paths. Pinned by
`binding::duplicate_role_name_refuses`.
Two low items:
- `SourceBindError::Display` had no test (its renderer stays dead until a
decoupled-supply caller lands, #124). Added `source_bind_error_display_names_the_role`
pinning the message strings; reachability is deferred by design.
- The reverted fieldtest `SourceSpec` sweep leaves the corpus one more revival break
against the current engine API — carried, as the corpus is pre-existing bit-rot
unrelated to this cycle (documented in 9e30805 and on #275).
Suite: `cargo test --workspace` green (1321 passed, 0 failed); `cargo clippy
--workspace --all-targets -- -D warnings` clean. Spec + plan (git-ignored working
files) discarded.
closes#275
The CLI half of by-name source binding, plus the ledger record.
Every production run site that carries a ResolvedBinding — `run_signal_r`,
`run_blueprint_member` (sweep / reproduction), and the campaign re-run/trace path —
now keys its opened sources by role name via `key_supply(binding, sources)` and
drives the harness through `Harness::run_bound` instead of the positional
`run(sources)`. `key_supply` pairs each opened column with its declared role from
`binding.entries()` — the one place open-order and role-order meet, made explicit so
`bind_sources` verifies the wiring↔supply role match by name rather than by a
maintained canonical-order convention.
Because the current single-binding CLI derives both the `SourceSpec` roles (via
`wrap_r`) and the supply roles (via `key_supply`) from the same `binding.entries()`,
the bind cannot fail on this path — so the call site asserts the invariant with
`.expect`, matching the adjacent `close_handle.expect("ResolvedBinding guarantees a
close entry")` idiom. The named `SourceBindError` refusal path lives in
`bind_sources` for future decoupled-supply callers (independently-built multi-feed /
recorded sources, #124), where a mismatch becomes reachable.
Ledger: a C4 realization note (supply resolved by name into declaration order, so
supply order is no longer load-bearing; the tie-break guarantee is unchanged) and a
scoped C23 refinement (a `SourceSpec.role` is load-bearing for source binding; every
other flat-graph name stays a non-load-bearing raw-index symbol).
The fieldtest-corpus `SourceSpec` sweep (planned Task 5) was reverted: the fieldtest
packages already fail to build against the current engine API for reasons unrelated
to `SourceSpec` (bootstrap arity, removed `InputSpec`, drifted
`Recorder`/`SimBroker`/`RMetrics`, renamed `Scalar` helpers) — pre-existing bit-rot
from earlier cycles. A partial `SourceSpec` migration neither revives nor further
breaks them, so the scope decision to touch them (premised on their being
otherwise-buildable) was withdrawn; reviving the corpus is separate from #275.
Verification: `cargo test --workspace` green (0 failed; the real-data OHLC channel
e2e exercises the migrated `run_bound` path byte-identically); `cargo build
--workspace --all-targets` clean; `cargo clippy --workspace --all-targets -D
warnings` clean.
Drift review (architect) over a55e4cf..HEAD found the cycle substantially
clean — C25 closed vocabulary, C1 determinism/behaviour-preservation, the
additive-serde widening, exhaustive StageBlock matches, and the uniform exit-3
convention all hold. Two drift items resolved:
- RATIFY: the `SilencedPanic` member-boundary panic-hook silencer (added by the
#272 implementer, not named in the spec) is a legitimate mechanism — it keeps
"recorded, campaign continues" observably true on stderr by suppressing the
default crash backtrace around each contained `catch_unwind`. Its mutex
serialises only the ref-count/hook-swap (O(1)), never member computation, so
C1 disjoint-parallel determinism is preserved. Documented in the ledger's
#272 realization paragraph rather than left as undocumented global state.
- FIX: `cell_fault_kind_label` hand-wrote the snake_case strings that must match
`CellFaultKind`'s serde `rename_all` (two sources of truth an aggregate over
campaign_runs.jsonl could silently diverge from). Pinned with a test asserting
each label equals the serialized form; the efficient `&'static str` stays.
(The #272 commit's own concern-driven doc fixes and the wf panic-containment
test landed in d3b1a1a; this commit carries only the two audit-phase items.)
Suite: cargo test --workspace green (1311 tests, 0 failed); clippy clean.
closes#272
A member fault (no-data, bind, run, or a caught panic) is now a recorded
per-cell outcome instead of aborting the whole campaign and discarding every
already-computed cell. The incident that motivated this (a 22-instrument
campaign lost ~36 healthy cells ~6.7 min in because Copper had an archive gap)
now completes: the healthy cells persist, the gap cell is recorded as failed,
and the run exits 3.
Direction (owner decision 2026-07-14): run to completion and report
compromised results; no coverage preflight, no window synthesis.
Containment granularity:
- The CELL for a sweep-stage member fault (a grid hole structurally
compromises winner selection, so the whole cell fails).
- The FOLD for a walk_forward member fault (independent time windows): the
surviving folds pool into the family, failed folds are recorded as
StageRealization.window_faults, and the summary names the ratio.
- aura-registry: additive CellFault / CellFaultKind (closed:
no_data|bind|run|panic|window) / WindowFault / CellCoverage, plus
fault/coverage fields on CellRealization and window_faults on
StageRealization — all serde-default-skipped, so pre-#272 campaign_runs
lines parse and round-trip byte-identical.
- aura-campaign: run_cell returns a fault-annotated CellRealization instead of
Err (execute's accumulate-then-append-once tail is unchanged and now
persists every healthy cell + the one run record); a `contain` split keeps
ExecFault::Registry and doc-shape preflight faults global while Member/Window
become per-cell/per-fold. Member panics are caught with
catch_unwind(AssertUnwindSafe) at all three member-run sites (sweep IS/OOS)
and recorded as MemberFault::Panic — a member panic no longer aborts the
process. The wf stage partitions Registry faults (global) from Member/Window
(per-fold) and filters faulted-fold placeholders (the
"faulted-member-placeholder" broker sentinel) out of the persisted family.
- aura-cli: exec_fault_prose gains the Panic arm; CliMemberRunner::window_coverage
derives effective bounds + interior gap months from the #264 archive
primitives; present_campaign prints per-cell failure notes + a completion
summary and threads the failed-cell count; a run with >=1 failed cell exits 3
("completed with failed cells") uniformly across `aura campaign run` and the
dissolved sweep/walkforward/mc/generalize verbs (exit_on_campaign_result).
Usage stays 2, refused-before-running stays 1, clean stays 0.
Tests: the global-abort pins flip to containment (execute + the two wf fault
tests → fold-containment + all-folds-fail-the-cell); new panic-containment
tests on both the sweep path (PanicRunner) and the wf path (this commit adds
the wf mirror the loop left uncovered); a new gapped-archive e2e (one covered
cell + one gap cell → exit 3); the ~14 CLI exit-1 pins move to the exit-3
register; a pre-#272-line byte-identical round-trip guard.
Suite: cargo test --workspace green (1309 tests, 0 failed); clippy clean.
Decision log: #272 comments (fork rationale, the fold Registry/Member split,
the placeholder sentinel, uniform exit-3).
Follow-up (minor, not blocking): the plan under-scoped Task 1 to aura-registry
though the additive fields also touch aura-campaign's exec.rs literals — the
loop absorbed it mechanically; a future plan for a cross-crate additive-field
change should scope every crate's construction sites in the first task.
closes#256
Fork B (owner decision 2026-07-14): the dissolved walkforward/mc
translations' leading sweep executed the full grid over the whole campaign
window and persisted a Sweep family, yet only the enumerated parameter
points ever crossed the stage seam (the wf stage re-sweeps them per IS
window itself). The leading stage is now the fieldless vocabulary block
std::grid: it enumerates, executes nothing, persists nothing.
- aura-research: StageBlock::Grid ({"block":"std::grid"}), schema-strict
parse arm (empty slot list: every key but "block" is refused by the
generic unknown-slot check), PROCESS_BLOCKS entry, intrinsic-tier no-op
arm; the vocabulary test's non-empty-slots guard carries a pinned
std::grid-only exception (a nominal slot would misdescribe the
vocabulary to describe_block consumers).
- aura-campaign: the inter-stage seam is a typed two-armed StageFlow
(points-only vs executed members); gate / mc-per-survivor fence the
points-only arm with defensive PipelineShape faults; preflight admits
std::grid only as the first stage and only immediately before
std::walk_forward (every other neighbor consumes executed reports).
- aura-cli: translate_walkforward / translate_mc lead with
StageBlock::Grid; the two family-shape E2E pins flip to zero Sweep
families; translate_generalize keeps its executed sweep(argmax) — its
generalize stage consumes the argmax winner report as the cell nominee.
- docs: dated #256 amendment in the ledger's verb-dissolution narrative;
the authoring-guide vocabulary transcript gains the std::grid line.
Behaviour preservation: the exact-grade real-data pins
(walkforward_real_e2e_pins_the_exact_current_grade,
mc_r_bootstrap_real_e2e_pins_the_exact_current_grade) pass unmodified —
survivor points reach the wf stage in the same odometer order as before.
Measured (the #256 acceptance measurement; debug build, real GER40 2025,
2x2 grid, `aura walkforward --real`, 3 runs each):
before (a55e4cf): 6.27 / 6.18 / 6.18 s
after: 4.52 / 4.49 / 4.45 s (~ -27% wall clock)
Suite: cargo test --workspace green (0 failed); clippy clean.
Decision log: #256 comments (fork rationale incl. the StageFlow seam and
the slot-guard exception).
The second risk-regime variant vol_tf{period_minutes, length, k}
computes the vol estimator over completed time buckets: an H1 signal
gets an H1-matched stop in the research matrix instead of a hand-scaled
minute stop (the issue's k-inflation workaround retires). Additive
externally-tagged serde (stored Vol documents keep their content ids);
the executor arm wires the VolTfStop primitive via the builder+bind
chain; validate checks period_minutes/length/k positivity per regime.
The member-manifest round-trip holds for both variants (C1): vol_tf
members stamp stop_period_minutes/stop_length/stop_k and the reproduce
path re-derives the VolTf stop whenever stop_period_minutes is present
— never a silent default-Vol fallback. The Regimes slot label and the
unit notes name the new variant (period_minutes IS the stop's
timescale); glossary, authoring guide, and design ledger record the
second variant. Default regime and sugar paths byte-untouched.
Coverage: node units (rollover-only emission, bucket-delta math, the
constant-|delta| correspondence with the per-cycle regime), executor
fold, serde/validate units, the manifest round-trip unit, and a
hostless two-regime e2e (distinct ordinals; vol_tf members stamp their
timescale, vol members do not).
closes#262
Each cost component's knob (cost_per_trade / slip_vol_mult /
carry_per_cycle) now accepts one number for every cell — today's form,
byte-identical on the wire so stored documents keep their content ids
(CostValue's custom serde, the Axis precedent) — or an instrument-keyed
map resolved per cell at member construction. A mixed-scale matrix
(GER40 ~2e4, EURUSD ~1.1) keeps consistent cost units in ONE document:
the N-copies workaround retires and generalize-under-constant-costs
becomes expressible again.
Validation is strict both ways at the intrinsic tier: a map missing a
campaign instrument, or naming one the campaign does not list, refuses
at validate with prose naming the component and instruments (no silent
default — a partial map would reproduce exactly the silent unit
inconsistency the issue reports). The instrument threads through
cost_knob/cost_nodes_for/run_blueprint_member from the cell (run side
and persist re-run side receive the same value — the C1 drift-alarm
lockstep); the manifest stamps the resolved per-cell value under the
unchanged cost[k].<knob> key, and the sugar/reproduce paths pass an
inert instrument (their specs are scalar by construction). Fork
decisions and the discarded first attempt: issue #260 comments.
New coverage: serde round-trips (map form; scalar stays bare), validate
cross-check units, both prose directions pinned, and two hostless e2es
over the synthetic SYMA+SYMB archive — per-cell resolution visible in
the member manifests, and the validate refusal.
closes#260
Cycle-close audit over the /boss batch 84e1075..bdafbde (#258#259#264#266#247#265#269). Architect verdict: substance clean — C1
byte-identity (conduit serde-skipped, pinned floats verbatim, uncosted
bit-identical), C10 one-home-for-cost (all four conduit consumers read
the already-netted series), C18 (conduit off the wire, --version and
manifest single-sourced) all hold. Two medium debt items, both fixed
here rather than carried:
- render_bind_error's catch-all Debug-framed the remaining BindError
variants, making #269's no-identifier-on-stderr claim argv-gated
rather than structural. The match is now exhaustive: DuplicateBinding,
EmptyAxis, EmptyRange render as axis-usage prose; a Compile fault — a
blueprint defect, not a usage error — renders as a prose frame with
the compile detail explicitly labelled internal (per-variant
CompileError prose belongs to the graph-build surface, not this
boundary). Unit tests pin the arms.
- The #265 knob-unit notes covered constant and vol_slippage but not
carry.carry_per_cycle, which carries the identical price-unit-vs-R
trap; the note set and its pins now cover all three cost components.
No regression scripts are configured (the architect is the sole gate);
full workspace suite green, clippy clean. Spec and plan working files
discarded per the audit lifecycle.
refs #265 refs #269
render_bind_error's catch-all Debug-framed UnknownKnob although its
payload is already a fully-prosed message; the variant now renders the
payload alone. The two tests that pinned the frame verbatim repoint to
the prose fragments. Exit 2 unchanged. Completes the #247 defect
family: no Rust identifier reaches a user's stderr on either verb path.
closes#269
campaign introspect --unwired now annotates the four silently
misreadable knobs with unit/semantics sub-lines: cost_per_trade is a
price-unit numerator charged as cost/|entry−stop| in R (not a cost in
R); slip_vol_mult multiplies the per-cycle vol estimate; vol.length
smooths the estimator and does not set the stop's timescale; vol.k
scales the stop distance (the risk-unit lever). Rendered additively
via a new OpenSlot.notes field, so the sibling tests pinning the slot
hint lines verbatim stay green byte-identically.
The glossary's cost-model and risk-regime entries mirror the same
semantics inline (two-sentence convention kept), the risk entry
pointing at #262 for the timescale-matched variant.
closes#265
The blueprint-sweep terminal rendered BindError via {:?}, leaking
KindMismatch { .. } and MissingKnob(..) Rust Debug structs where the
sibling diagnostic on the same verb ships prose. Both now render in
that register — the axis name, the expected-vs-supplied kinds resp.
the unbound knob, and the --list-axes pointer; exit stays 2.
Scoped out (same defect family, different verb path): the walkforward
path's UnknownKnob wrapper still prints its Debug-ish frame around an
already-prose payload and is pinned verbatim by two existing tests;
filed as a follow-up rather than widened into this slice.
closes#247
aura --version now prints 'aura 0.1.0 (<commit>)', the commit sourced
from the same AURA_COMMIT build provenance the run manifest stamps
(option_env! at build time, 'unknown' fallback, dirty suffix included)
— a pre-run freshness probe: a stale binary is now distinguishable from
an engine bug at the CLI surface, and research docs pinning
'Engine: aura @ <sha>' can verify the binary they invoke.
The version string is memoized as a OnceLock-leaked &'static str:
clap 4.6's builder Str accepts only &'static str (no From<String>), so
the owned-String alternative a quality pass suggested does not build —
verified, held with evidence in the loop report.
closes#266
aura data list prints the archive's known symbols sorted, one per line
(DataServer::symbols() over the project-resolved archive root — the
discovery step before aura data coverage or scoping a campaign's
instrument matrix). An empty or absent archive prints a 'no symbols'
prose line and exits 0, per the verb corpus's empty-result register.
Pure report fn with unit tests; the headline e2e runs hostless over
the synthetic SYMA+SYMB archive.
Together with the coverage verb this closes the inventory gap: an
agent operating through the CLI alone can now discover instruments
and their per-month gaps before authoring a campaign.
closes#264
aura data coverage <SYMBOL> prints the archive's monthly file-index
coverage: a span line (first..last present month) and either an explicit
'no gaps' line or one 'missing: YYYY-MM..YYYY-MM' line per interior
contiguous hole. The Copper failure mode — a campaign aborting mid-run
because a first/last-bounds check passed while the window start had no
data — is now visible before any run (the real archive reports
'Copper missing: 2017-04..2019-09'). An unknown symbol (no archive
files) refuses on stderr with exit 1; informational absence stays
prose + exit 0 per the verb corpus convention.
Mechanics: list_m1_months goes pub in aura-ingest (archive_extent
deliberately walks past gaps and cannot report them); a new two-level
'aura data' clap namespace follows the Nodes precedent; the archive
root resolves through the normal project path (paths.data override,
data-server default otherwise). Pure report fn with unit tests for the
refusal, the gapless span, and the collapsed-range shape; the headline
e2e runs hostless over a new gapped synthetic-archive fixture.
refs #264 (cut 2, aura data list, follows separately)
The OOS bootstrap conduit RMetrics.trade_rs becomes net_trade_rs and
carries the COST-NETTED per-trade R (r − cost_in_r, trade order). Every
conduit consumer is thereby net-when-costed: the monte-carlo pooled-OOS
and per-survivor bootstraps, the walk-forward oos_r pooling, and the
deflation null-max — which previously compared a net observed statistic
against a gross-resampled null whenever a costed campaign selected on
net_expectancy_r. An uncosted run is bit-identical (empty cost stream
⇒ cost 0.0 per trade), so every existing golden pin stays green.
Design: one conduit, no knob — an explicit net: knob would let a costed
campaign silently produce a gross headline again (the exact misreading
of the issue's evidence). Per-member RMetrics scalar fields stay gross;
net_expectancy_r keeps its meaning. Wire shape unchanged (serde(skip)).
The net series is materialized as a separate expression in summarize_r;
the pinned-float expressions (net_sum, the SQN pair, the lockstep
r_metrics_from_rs copies) keep their tokens verbatim. Fork decisions
and rationales: issue #259 comments.
New coverage, both hostless over the synthetic SYMA archive: a costed
campaign twin shifts the pooled-OOS bootstrap (sweep→gate→wf→mc) and
every per-survivor bootstrap (sweep→mc) below its gross sibling, with
the trade population unchanged; a unit test pins the conduit as the
cost-netted series with the empty-stream degeneracy. Existing conduit
tests renamed with the field.
Verified: full workspace suite green (71 result blocks), clippy clean,
zero bare trade_rs tokens remain, ledger conduit prose updated in place.
closes#259
Every hand-rolled test-sandbox helper keyed its directory on
std::process::id() under env::temp_dir(), so the pre-create wipe never
matched a prior run's path: one directory stranded per helper site per
test-binary invocation, >50k dirs / 15.5 GiB on the 16 GiB tmpfs by
2026-07-13.
The remedy extends commit 84e1075's knob-lab pattern to every site:
fixed, tag-keyed, PID-FREE names under the build-tree tmp anchor, each
site keeping its pre-create remove_dir_all — which now genuinely
reclaims the previous run. Integration/bench targets use
env!("CARGO_TARGET_TMPDIR"); src-internal unit-test helpers (cargo sets
that var only for integration/bench targets) derive the same anchor
from env!("CARGO_MANIFEST_DIR") + ../../target/tmp. Residue is bounded
to one directory per site, on disk instead of the tmpfs, per checkout.
One deliberate exception: project_new.rs's tmp() stays under
env::temp_dir() because two of its tests (new_outside_a_work_tree_*)
need a base genuinely detached from any git work tree, and target/
lives inside the checkout's work tree. Its name carries a per-checkout
hash discriminator instead, so concurrently running checkouts (which
share /tmp) cannot race on the fixed name while each run still
reclaims its predecessor.
tempfile-RAII was considered and rejected (issue #258 decision log):
it cannot cover the process-lifetime OnceLock scaffolds (statics never
drop), adds a dependency, and still strands kill-leftovers on the
tmpfs.
Verified: full workspace suite green (incl. the new RED regression
test temp_cwd_sandbox_does_not_leak_under_env_temp_dir), clippy clean,
sandboxes observed under target/tmp with stable names across runs.
Stale pre-fix PID-keyed dirs in /tmp are not swept by this change and
age out only by manual cleanup.
closes#258
probe_window drained a source's entire close column just to learn its
first and last bar timestamp; both live callers (open_real_source and
campaign_window_ms on the campaign trunk) now resolve through
aura-ingest's new archive_extent(): list the symbol's SYM_YYYY_MM.m1
files, load only the boundary months via the existing loader seam, and
walk across gap months forward/backward — O(2 file loads) typical
instead of O(archive). Empty-window refusal semantics are unchanged
(pinned). Two characterization tests captured the resolved windows
against the OLD implementation over the synthetic per-test archive and
stay green unchanged after the swap.
Measured: the probe itself drops 366ms -> 13ms (~28x) on the full
2014-2026 GER40 archive; end-to-end command wall-clock moves only
~2-3% because the sim loop dominates — the fix removes an
O(archive-size) term, not the dominant cost.
closes#252
blueprint_walkforward_family's pre-flight executed the full first-IS-
window sweep via blueprint_sweep_over and discarded the result, purely
to surface axis errors once before the parallel window fan-out (#177).
validate_axis_grid now drives the sweep terminal's own resolve/arity/
kind checks with a constant placeholder report — same single-sourced
rejection wording, no member run, no roller derivation needed.
Scope correction against the issue text: this path serves only the
synthetic (non---real) walkforward. The --real trunk routes through
verb_sugar into aura-campaign's [Sweep, WalkForward] process, whose
leading full-window sweep is a separate, larger duplication — re-filed
with corrected attribution in the issue's closing comment.

Env::data_path() handed paths.data to the data layer verbatim, so a
relative value resolved against the invoking process's cwd — aura run
from a project subdirectory silently read a different archive location
than from the root, while runs/ stayed anchored. Relative values now
join onto the project root, matching runs_root() and the [nodes]
pointer resolution; absolute values and the no-project default pass
through unchanged. RED-first unit test pins the root-anchored
resolution.
closes#254
RunManifest gains defaults: Vec<(String, Scalar)> — the wrap-prefixed
bound_param_space() of the signal, read after axis reopening, so a
bound param an axis overrode has already left the space and flows
through params instead (disjoint by construction; verified end to end:
a sweep member's overridden fast.length sits in params while
slow.length/bias.scale sit in defaults). params keeps its "what varied"
semantics and stays the reproduce input. One-directional serde
widening (#[serde(default)]) per the selection/instrument/topology_hash
idiom — old records deserialize with an empty defaults; unlike the
Option fields it always serializes, mirroring params. ~20
struct-literal sites across five crates gained the field
(compile-mandated breadth, no behaviour change at those sites).
The C14 ledger records the underlying decision (2026-07-13): generated
outcome records spend redundancy on direct readability (single writer,
cannot drift); authored intent artifacts admit none (every redundancy
is a drift site) — so the fix lands in the manifest, never the
blueprint.
Verification: RED test run_manifest_stamps_untouched_bound_defaults
green; cargo build --workspace; cargo test --workspace green; clippy
-D warnings on the touched crates; binary-level sweep exclusivity
check.
The four _open blueprints leave the user-facing gallery
(crates/aura-cli/examples/) and become test fixtures; the closed twins
are now the only example corpus (bound params are overridable defaults
since #246, so the closed files serve both run and sweep).
Compile-time embeds follow the move: the emit_* generators and the
shipped_*_serialize byte-pins target tests/fixtures/ (the open fixtures
stay builder-generated and byte-pinned — regenerating after the move
left the tree clean), load_open_r_sma and the axis-probe read the
fixture, and the walk-forward refit test plus the `aura graph` default
sample switch to the closed r_sma.json. graph_construct's open-fixture
tests swap example() -> fixture(), their names dropping the now-false
"shipped example" claim; a new e2e test pins the relocation property
(all four fixtures load and introspect, the gallery holds exactly the
four closed examples).
Intermediate state: cli_run.rs / research_docs.rs / project_load.rs
still reference the old example paths and fail at runtime until the
follow-up migration commit (MIGRATE sites move to the closed twins,
NEEDS-OPEN sites to the fixtures).
Verification: cargo build --workspace; cargo test -p aura-cli --bin
aura; cargo test -p aura-cli --test graph_construct; the three ignored
emit generators re-run byte-stable.
Task 6 of the bound-override cycle: SIGNAL_OPEN_JSON_STD and its write
retire — aura new scaffolds signal.json alone, and the project CLAUDE.md
quickstart advertises run AND sweep against that one file (the sweep line
overrides the bound fast.length; --list-axes shows open + bound axes).
The data-only e2e loop proves it end to end: scaffold, run the closed
starter, sweep it via an override axis, and assert signal.json is the
only starter blueprint. The authoring-guide's starter-pair sentence is
retargeted; the last signal_open reference outside the unrelated #196
fixture string is gone.
refs #246
Task 5 of the bound-override cycle. The campaign executor and its gates
accept an axis naming a bound param everywhere the open surface was
already accepted: CliMemberRunner::run_member re-opens the override set
on the cell's probe space and raw reload (raw_bound_overrides_of — the
campaign document's axis names live in strategy coordinates, matched
against bound_param_space directly), the P3 preflight in
validate_before_register threads the same set so the executable-shape
check passes, and aura-registry's validate_campaign_refs treats a bound
name as a valid axis (open space wins the arm order; the kind check
still faults a mismatched axis over a bound path).
The CLI-side helper family is named by coordinate system now:
wrapped_bound_overrides_of (wrap-prefixed, sweep/wf/reproduce) beside
raw_bound_overrides_of (campaign). A fresh post-block quality review
found no correctness defect; its two stale-comment findings (renamed
helpers cited under their old names) are fixed in this commit.
refs #246
Task 3-4 of the bound-override cycle. The family boundary derives the
override set from the invocation's axes (override_paths: an axis in the
open space passes through, one naming a bound param re-opens it in
strategy coordinates, one matching neither is refused with a message
pointing at --list-axes) and threads it through the axis probe and every
per-member reload (blueprint_axis_probe_reopened / reopen_all), so probe
and members stay slot-identical. The 'fully bound; nothing to sweep'
refusal retires; identity stays the authored document (the topology_hash
probe reload is never re-opened).
--list-axes now prints the bound surface after the open knobs — one
'<bp>.<node>.<param>:<KIND> default=<value>' line per bound param,
unconditionally (a bound param is an equally re-openable axis regardless
of how many knobs are open beside it).
Walk-forward (blueprint_sweep_over, blueprint_walkforward_family,
run_oos_blueprint) and reproduce (reproduce_family_in plus the
campaign-side trace re-run) derive the same set silently from recorded
manifest param names (bound_overrides_of), so a family that swept an
overridden bound param re-derives bit-identically.
refs #246
The op-script error seam (OpError::UnknownNodeType) now consults the
same tier-hint logic as the blueprint load path: outside a project the
hint names the missing Aura.toml, inside a data-only project it names
the missing node crate and the attach verb. Hint texts shared, load-path
behaviour and the op-error prose byte-stable, exit codes unchanged.
closes#244
An existence pre-check on the [nodes] pointer target fires before the
crate pipeline: the refusal names the absent directory and keeps the
[nodes] context, instead of leaking cargo metadata's os-error wrap.
Existing-but-broken crates keep the ArtifactMissing/CargoMetadata
errors under the pointer prefix.
closes#245
RED pin: a_missing_nodes_pointer_dir_refuses_without_the_cargo_metadata_leak
(project.rs unit tests) — the refusal must name the absent directory and
keep the [nodes] context, with no cargo-metadata wrap.
refs #245
aura new and aura nodes new follow their git init with a best-effort
initial commit (inline committer identity, warning-never-fatal, skipped
whenever the init itself was skipped per #204), so a fresh project's
first run stamps a real commit instead of an empty provenance block.
closes#243
probe_window's two empty-result exits now route through a distinct
no_data_in_window refusal (requested bounds + archive path); its callers
have already proven the symbol present via has_symbol, so the old
"no local data for symbol" reuse misattributed a window fact to symbol
absence. The genuinely-unknown-symbol message and exit codes stay.
closes#242
Consumer-POV fieldtest evidence for the two-tier project model: the
data-only quickstart, the role-2 attach loop, real-data usage inside a
data-only project, and the refusal surfaces all match the docs.
Inline fixes for two of the friction findings:
- docs/project-layout.md: the day-in-the-life run example now shows real
Unix-ms window bounds instead of bare years (--from/--to take ms).
- `aura new` --help one-liner no longer calls the project a crate.
Remaining findings tracked on the Gitea queue (empty first-manifest
provenance on a fresh scaffold; misleading no-data message for an
uncovered --real window; the tier hint missing on the graph-build path;
the raw cargo-metadata leak for a missing [nodes] dir).
refs #241
- CLAUDE.md invariant 9 amended end to end: a project is a directory
anchored by a static Aura.toml, data-only by default; native node
logic lives in attached node crates (the nodes/ antecedent removed —
user decision 2026-07-12, re-opened by the role model's diagnosis).
- docs/project-layout.md reworked to the two tiers (data-only default
tree + sibling node crate, workspace note under the crate half); the
day-in-the-life walkthrough now attaches the project's node crate
once and wires the namespace the shown command actually produces.
- docs/authoring-guide.md: data-only quickstart (closed run target,
open sweep target) + `aura nodes new` as the native entry; section
cross-reference updated.
- docs/glossary.md: new "data-only project" and "node crate" entries;
Aura.toml and manifest entries carry the tier split.
- docs/design/INDEX.md: realization note (wiring-only tier, #241) in
the project-environment section.
- rustdoc: `[nodes]` intra-doc-link escapes in project.rs/main.rs.
Full gates green: workspace suite (all binaries), clippy -D warnings,
doc build without new warnings.
closes#241
- New clap family `aura nodes new <name> [--engine-path] [--namespace]`:
scaffolds a node crate as a SIBLING of the project root (Cargo.toml
with the aura-core path-dep, the parameterized Scale starter node,
roster macro, crate-scoped .gitignore + CLAUDE.md, own git repo) and
appends the `[nodes] crates = ["../<name>"]` pointer to the project's
Aura.toml. Refuses outside a project, on any existing [nodes] section
(incl. an empty crates array), and on an existing destination; joins
the load-phase bypass beside `aura new` (a scaffolder must work in an
unbuilt tree).
- The old single-tier scaffold() is gone; the crate templates live on
in scaffold_node_crate; dead-code bridges removed with their callers.
- tests/project_nodes.rs: attach + refusals + namespace override + the
full role-2 loop (scaffold, cargo build, vocabulary resolves
<ns>::Scale end to end).
- tests/project_sweep_campaign.rs fixture reworked to the two-tier
shape (aura new + aura nodes new --namespace knob_lab); the two
campaign acceptance tests are byte-unchanged and green.
refs #241
- NewCmd drops --engine-path/--namespace (they belong to the node-crate
scaffold); dispatch_new emits Aura.toml + .gitignore + two std-only
starter blueprints + CLAUDE.md, git init, no crate, no build step.
- Two starter blueprints because run requires a closed blueprint while
sweep requires open knobs: signal.json (closed, run target) and
signal_open.json (fast.length free) — the scaffolded CLAUDE.md
quickstart lines are both verified live.
- The crate templates survive untouched for the attach verb; old
scaffold()/scaffold_spec() carry a dead-code bridge until it lands.
- project_new.rs realigned: data-only file set, no-build run headline
(stdout report, C1 byte-identity, commit-only provenance, negative
runs/ assert), advertised-sweep headline (#218 gate passes, store
lands project-local).
refs #241
A project-namespaced (::) unknown type id now hints by tier: outside
any project the existing "no Aura.toml was found" text stays
byte-identical; inside a data-only project the hint names the missing
node crate and the attach verb (aura nodes new); a loaded node crate
gets no hint (the vocabulary error carries the message).
refs #241
- ProjectProvenance namespace/dylib_sha256 widen to Option (Tier-1
additive serde): a data-only run stamps commit-only provenance; old
string-field manifests keep parsing.
- The load boundary tier-selects: a [nodes] pointer list in Aura.toml
(one entry honored; MultiCrate / pointer-context refusals) loads the
pointed-at crate; a root Cargo.toml stays the pre-#241 native project,
unchanged; neither means data-only (std vocabulary, project-local
runs/, both-tier provenance).
- ProjectEnv splits into directory facts + Option<NativeEnv>; the crate
pipeline (metadata -> artifact -> staleness -> ABI -> charter)
relocates byte-identical into load_crate.
- e2e fixtures: dataonly-project, multicrate-project,
nested-nodes-project (a pointer crate resolves and stamps its
namespace end to end).
refs #241
The viewer threads the model's doc through normalizeModel into both
composite view states — appended to INFO.B (collapsed box) and INFO.C
(expanded cluster frame) — and shows the root composite's doc as a muted
header line (#rootdoc span in GRAPH_HEAD, empty when absent; the DOM
population sits in the browser-only block, the same boundary as the
breadcrumb). viewer_tooltip.mjs pins the doc'd cases beside the
byte-exact un-doc'd pins; sample-model.json gains the additive doc key;
e2e drives aura graph over a nested-doc blueprint into the emitted page.
closes#125
The NotFound arm of emit_chart now queries the recorded campaign runs:
records with a persisted trace_name whose stored campaign document
carries name == ARG. A unique match re-dispatches the existing charting
path onto the resolved handle; several matches refuse listing the
candidate handles in append order (refuse-don't-guess — re-running a
named invocation legitimately yields {campaign8}-0, -1, ...); zero
matches keep the not-found message verbatim. The exact trace-store
handle always wins; the name never becomes a store key (C18 untouched).
Guide §3 and the glossary tap entry document the name alternative.
closes#238
fit_wf_ms_sizes (pure, unit-tested) passes the fixed 90/30/30-day roller
through byte-identically whenever it fits the resolved campaign window,
and scales it down preserving the 3:1 IS:OOS ratio (step = OOS, one roll
at the minimum) when the window is shorter — so mc/walkforward --real
over a ~30-day window run to completion instead of dead-ending at the
executor with a remedy unreachable from the verb surface. Both dispatch
sites consume the fit; the executor's own check stays for authored
process documents. Verb help documents the fit.
closes#239
persist_taps_from now filters the tap vocabulary through campaign_run's
own tap_channel classification (exposed pub(crate)) and drops the net
channel: every generated sugar campaign carries an empty cost section by
construction, so net_r_equity was unproducible there and the executor's
skip notice named a remedy (add a cost block to the campaign document)
unreachable from the sweep/walkforward verb. The authored-campaign path
keeps the notice verbatim — there the user wrote the document and the
remedy is reachable. The two full-vocabulary pins move to the producible
subset (deliberate pin move, documented in their doc comments).
closes#240
The generated sugar campaigns carry an empty cost section by construction,
so net_r_equity can never be produced on the sweep/walkforward --trace path;
requesting it makes the executor print a remedy (add a cost block to the
campaign document) unreachable from the invoked verb.
refs #240
TraceStore::name_kind and read_family resolved taps exactly one
directory below the family handle, so the per-member fan-out layout
sweep/walkforward --trace writes since #224
(<name>/<cell>/<member>/index.json) classified as NotFound and
`aura chart <printed handle>` exited 1. Both sides now resolve depth-1
(campaign nominee layout) and depth-2, with depth-2 members keyed
<cell>/<member> (deterministic sort, C1); the on-disk layout is
unchanged. emit_chart's not-found message no longer suggests re-running
with the unknown handle as --trace (the data-creating command cannot
take an output handle as input); the message prefix stays pinned.
Milestone-fieldtest finding B1 (fixtures: 09da04f); verified against
the fieldtest's own on-disk family and the campaign depth-1 sibling.
The no---from/--to fallback in dispatch_generalize probes EACH listed
symbol's full archive window (same partial bounds threaded through) and
resolves the one shared campaign window as their intersection — latest
start, earliest end — instead of symbols[0]'s window alone, so the
cross-instrument floor is measured over a genuinely common period.
Disjoint archives refuse at runtime (exit 1) naming each symbol's span.
The intersect-or-refuse arithmetic lives in the pure
intersect_shared_window helper (unit-tested: single symbol, overlapping,
disjoint); the explicit --from+--to path stays byte-identical. The
superseded shape test is renamed to
generalize_without_explicit_window_resolves_a_shared_window_and_completes
with its doc comment reworded to the intersection contract.

Architect review over dd23ea3..HEAD (the #234/#152 cycle, 6 commits).
What holds (architect-confirmed): CostSpec is a closed, deny-unknown-
fields vocabulary with typed slots mirroring RiskRegime, field names
conforming to the builders' ParamSpec names; cost-less docs hash
byte-identically (C18); cost threads through the single MemberRunner
seam so every campaign stage nets uniformly; costed families reproduce
bit-identically incl. Carry; the #221-deleted leg is rebuilt optional
(net = gross under the empty model); both cost_graph leaks replaced by
the interned single source (#152).
Resolved this close: [high] the C10 realization notes contradicted
shipped reality — the two 'wired on the run path via --cost-*' claims
carry superseded-annotations, the 0084 carried-debt note a discharged-
annotation, and a new cycle-net-r realization documents the campaign
cost block, the net-by-default decision, the manifest/reproduce
round-trip, and the returned net_r_equity tap; [medium] two dangling
persist_traces_r docstring references reworded to what exists;
[medium] the one-knob-per-cost-node invariant behind the manifest
round-trip is now unit-pinned (exactly one distinctly-named knob per
shipped builder).
Cycle spec and plan (git-ignored working files) discarded per
convention.
refs #234
TapChannel gains Net; tap_channel routes the full closed vocabulary
(producibility moved to the caller); the trace path drains the sixth
channel and persists the cost-adjusted net curve. A cost-less document
requesting net_r_equity keeps a skip notice, reworded to name the
remedy (add a cost block) — not a refusal. Two deliberate pin moves:
the absence pin re-pins to routed, the skip-notice e2e re-pins to the
reworded form. Post-review: positive write-path e2e added (a costed
GER40 campaign lands net_r_equity.json with the curve differing from
r_equity by the accrued costs).
Verified: routing pin + positive e2e green (real archive), full
workspace suite green, clippy -D warnings clean.
refs #234
cost_nodes_for (beside stop_rule_for_regime) is the one CostSpec ->
bound-builder binding — every component fully bound, so the wrapped
param space stays cost-invariant. run_blueprint_member joins the cost
rows into summarize_r (member metrics genuinely net) and stamps the
cost components into the manifest params; CliMemberRunner threads the
doc's cost. The re-run sides re-derive the model from the manifest:
reproduce via cost_specs_from_params (the #233 stop pattern — a costed
family reproduces bit-identically) and persist_campaign_traces binds
the same model so the C1 drift alarm compares like with like.
Hand-computed pin: a constant cost model yields
net_expectancy_r == expectancy_r - cost_per_trade/|entry-stop| on a
synthetic member.
Verified: full workspace suite green, clippy -D warnings clean; in-loop
spec + quality gates passed per task.
refs #234
wrap_r accepts an optional CostLeg (cost node builders + the tx_cost/
tx_net channels); non-empty rebuilds the #221-deleted wiring — the
cost_graph fed by the executor's four geometry outputs, the vol-proxy
RollingMax/RollingMin/Sub (back from cfg(test) to production) feeding
each vol_slippage component, the interned cost[k].* names, a gated
4-col cost recorder in reduce mode (the summarize_r join input), and
the LinComb(4) net_r_equity curve in !reduce. All callers pass None —
behaviour-preserving; the entire suite green unchanged is the gate.
Co-temporality of cost rows with R rows unit-pinned.
Verified: full workspace suite green unchanged, clippy -D warnings
clean; in-loop spec compliant + quality approved (one held Minor: the
CostLeg doc's forward reference to cost_nodes_for, which task 4 lands).

The acceptance proof: hl_channel — a causal Donchian channel (Delay(1)
excludes the current bar, C2) consuming high/low/close roles, built from
rostered vocabulary, shipped as the r_channel/r_channel_open example
pair (builder + regenerator + serialize pins, the r_* pattern). Proven
at three layers: a non-gated loaded-vs-carve equivalence over inline
sources (non-zero-bias hardened per review), the unconditional synthetic
multi-column refusal, and archive-gated CLI e2e — aura run on GER40
end-to-end plus a sweep whose members run and reproduce 2/2
bit-identically.
Ledger: new C26 entry (the binding vocabulary — closed column set +
price alias, name-driven default + campaign data.bindings override,
canonical order = the C4 tie-break, Blockly-litmus argument, the #71
extension point for recorded non-price sources) and the C20/C24
scaffolding-clause annotations: the single-price data weld is retired,
wrap_r's remaining R-scaffolding retirement stays #159.
Verified: all proof tests green, full workspace suite green, clippy -D
warnings clean; independent quality review approved.
