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.

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 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.

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 campaign walk_forward stage picked its per-window in-sample winner by
optimize_deflated (argmax) unconditionally, dropping the stage's `select`
field, and both the preflight and the `walkforward` verb's `--real` campaign
sub-branch refused plateau:* with a forward-pointer here (the #210 decision-4
deferral; the synthetic non-`--real` sub-branch has accepted plateau since
#173). Honour plateau selection when no gate precedes the wf stage.
- Preflight: the plateau-in-wf refusal is narrowed to gate-preceded stages.
With no preceding gate the survivors are the full sweep grid, so the
parameter lattice (grid.axis_lens) is exact and optimize_plateau is sound; a
gate filters survivors below the grid, breaking the lattice, so plateau after
any gate stays refused. The refusal is static — document validity must be
data-independent (a gate's filtering depends on the data) — and keeps the
existing "a gated survivor subset has no parameter lattice" message, which now
describes exactly the only case it fires.
- Executor: run_walk_forward_stage threads the per-cell grid.axis_lens and picks
each window's in-sample winner via select_sweep_winner — the same dispatch the
sweep stage uses. (Argmax, deflate=true) is byte-identical to the old
optimize_deflated call, so the argmax grade and content-id pins are unchanged;
the plateau arms read axis_lens and ignore deflate.
- CLI: the walkforward verb threads --select through translate_walkforward /
run_walkforward_sugar (a walkforward-local param, not the shared four-verb
SugarInvocation), mapping the parsed Selection to the research SelectRule via
select_rule_of; the refusal and its select_is_plateau helper are deleted.
Scope is walkforward-only — the mc verb's wf-stage select is untouched.
The plateau:worst grade anchor (stitched_total_pips = -9683776.67) is distinct
from the argmax anchor (-10398606.67), proving the plateau path genuinely
changes winner selection rather than falling back to argmax. A gate-free plateau
process validates clean while a gate-preceded one is refused (a new
campaign-validate e2e). Argmax defaults stay byte-identical.
closes#215
The persist-side C1 drift alarm re-ran every nominee under the hardcoded
default vol-stop because CellRealization dropped the regime at the record
boundary — a non-default risk regime + persist taps false-failed C1 and
refused to persist a correct trace; two regimes over the same cell would
also have collided in one trace dir.
Fix at the record boundary: CellRealization carries regime + regime_ordinal
(serde-default + skip-serializing keeps pre-existing stored records
byte-stable), populated where the cell is realized; the regime->StopRule
binding is single-sourced in stop_rule_for_regime, shared by the member
runner and the persist re-run so the two sites cannot drift apart again;
campaign_cell_key appends -r{regime_ordinal} for non-default regimes
(default keys unchanged, no stored dir renamed).
closes#219, closes#212
The regime becomes the fourth structural coordinate of the campaign matrix, a
kept-separate axis (a peer of window, not aggregated-over like instrument):
- aura-campaign: CellSpec gains `regime` + `regime_ordinal`; the executor
resolves the regime list (absent/empty risk -> one default cell, ordinal 0),
runs a cell per (strategy, instrument, window, regime), and keys the nominee
map by the 3-tuple including the regime ordinal — so generalize aggregates
across instruments WITHIN a regime, never across regimes. Family names gain a
`-r{regime_ordinal}` discriminator so two regimes' families cannot collide.
- aura-registry: `CampaignGeneralization` gains `regime_ordinal` (with
`#[serde(default)]`, so pre-feature stored records still parse — pinned by a
new backward-compat test).
The existing single-regime execute tests shift their family ids by `-r0`; a new
test pins that two regimes yield distinct `-r0`/`-r1` families. `CellSpec.regime`
is write-only in this slice — its sole reader is the deferred member runner
(the next slice) — a held quality nit, seam-prep as the plan prescribes. Full
workspace suite green.
refs #210
The std::sweep selection triple (metric/select/deflate) becomes ONE
optional group, Option<SweepSelection>, serde-flattened so the wire
form keeps the flat slots: every existing document parses to Some and
its canonical bytes — and content id — are unchanged (golden pin
byte-untouched). A half-populated group is refused by the schema-strict
parser (all-or-nothing); a bare {"block":"std::sweep"} is the
selection-free sweep.
Campaign side: preflight permits a selection-free sweep only as the
pipeline's terminal stage (new ExecFault::SelectionFreeSweepNotTerminal,
prose in aura-cli's exhaustive exec_fault_prose); the executor's
selection-free arm appends the family exactly as before but records no
StageSelection and produces no nominee (recording one would fabricate
intent — #210 fork decision 1).
Introspection follows: the sweep block's schema table marks the group
optional; CLI introspection pins updated. New tests: group-or-nothing
refusals, selection-free round-trip + distinct content id, terminal-only
preflight accept/refuse, selection-free execute realization.

Task 1: the tap namespace is a closed vocabulary — tap_vocabulary()
(the wrap convention's four sink names; escalation = new entry or an
authored blueprint sink, never an open node-path namespace) with
DocFault::UnknownTap in validate_campaign (index-addressed, prose
enumerating the vocabulary via the single source), SlotKind::TapKinds
on the persist_taps slot, open-slot hint naming the taps. The 0107
deferral seam test split into its two 0109 pins (unknown tap refuses
at validate; a valid tap passes validate and hits the member-data
seam) — the deferral eprintln itself survives until task 3.
Task 2: CampaignRunRecord.trace_name lands serde-default sparse; the
claim contract holds across the seam — execute stamps the sentinel iff
persist_taps is non-empty, append_campaign_run composes
Some("{campaign8}-{run}") onto the stored line (safe prefix take at
the registry seam), execute mirrors the same derivation onto the
returned copy; None stays None; the hand-seeded byte-identity dump pin
survives (absent -> skipped).

The mc arm bootstraps the stage's incoming R-evidence with one
semantics, input-shaped by position (#200 decision 1): after a
walk_forward it pools the wf family's per-window OOS trade_rs in roll
order into ONE r_bootstrap (PooledOos); after sweep/gates it
bootstraps each surviving member's fresh in-memory series
(PerSurvivor, ordinals into the population family; a zero-trade
member records the engine's defined all-zero degenerate). Seeded from
the campaign doc's seed (C1). The wf family is read by reference from
the cell's families vec — no clone. run_cell's Generalize arm is an
explicit no-op naming the campaign scope.
The generalize phase runs after the cell loop (#200 decision 2):
nominees (last wf window's OOS report, else the sweep winner; None on
gate truncation) grouped by (strategy, window) across instruments via
a BTreeMap (deterministic order); >= 2 winners feed the shipped
generalization(), fewer record the shortfall (generalization: None,
missing named) — divergent per-instrument winners are exposed via
their params, never averaged away.

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

The roller refusal leaked its raw Rust form through ExecFault::Window
(SpanTooShort { span: (Timestamp(...), ...), need: ... }) — the one
break in the cycle's Debug-free prose seam. The detail now phrases
both roller refusals in the doc's own ms unit:
'in_sample_ms + out_of_sample_ms = N ms exceeds the campaign window
[a, b] (L ms)'. RED-first: the wf_roller_refusal_maps_to_window_fault
pin was flipped to the prose form (observed RED on the old Debug
output), then the map_err phrased; live repro confirmed against the
fieldtest fixture.

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).

The execution core: cells iterate strategy x instrument x window in doc
order (sequential — C1 keeps parallelism across sims); the sweep stage
enumerates the axes odometer (BTreeMap order, last axis fastest) through
the engine sweep over a ListSpace with lowest-index-deterministic fault
capture; selection dispatches optimize / optimize_plateau /
optimize_deflated (deflation nulls seeded from the campaign doc's seed);
gates filter per-member via member_metric (metrics.r == None fails an R
predicate, conservative); an empty survivor set truncates the cell's
realization and the run continues (exit-0 semantics at the caller). The
walk-forward stage rolls the declared cell window in ms (WfMode ->
RollMode), IS-sweeps ONLY the survivor points per window, stamps
manifest.selection on OOS winner reports, and appends a WalkForward
family; realization = CampaignRunRecord over untouched family records.
The loop's task-7 BLOCKED was review-exhaustion on the task-6 stub
wording the plan itself prescribed (task 7 deletes that stub); a fresh
post-loop quality review on the final diff returned one Minor — the
campaign_id prefix slice could panic on a malformed id — fixed as a
typed PipelineShape refusal + test (execute_refuses_malformed_campaign_id).
Known and accepted: a cross-cell member fault leaves earlier cells'
families as unreferenced records in the append-only store; nested
window/member parallelism can oversubscribe cores on large campaigns.
