Four tasks, one iteration: (1) the windowed IS-sweep + OOS-run helpers +
blueprint_walkforward_family (mirrors the hard-wired Stage1R walkforward arm one
substitution deep — loaded blueprint via blueprint_axis_probe); (2) the
--axis/--select parse grammar + IO wrapper (persist via put_blueprint +
append_family, content-addressed like aura mc) + the .json walkforward dispatch
arm; (3) the reproduce_family_in WalkForward branch (persist+reproduce land
together); (4) the E2Es (persist shape, reproduce bit-identical, no-axis reject,
malformed-safety) + the full clippy/suite gate.
Panic-safety: blueprint_sweep_over returns Result<_, BindError> (user --axis
fallible); a bad axis → clean in-closure exit 2 (mirrors the hard-wired arm's
select_winner handling), never a panic. reduce-mode members carry R-metrics (no
raw pip curve) → empty stitched equity, oos_r is the meaningful summary (C10
R-first). Closes the World/C21 milestone's last piece.

cycle 0096 tidy (clean). Architect drift review over ebebc24..HEAD: no drift,
no debt. Regression: no dedicated script (architect is the sole gate); its
"What holds" is non-empty (design commitments confirmed against the diff + a
green test run, not the commit body):
- Inv. 8 / 9: the cycle touches only crates/aura-cli (main.rs + cli_run.rs +
the ephemeral spec/plan) — no engine/registry/blueprint.rs change; those are
read-only callees.
- Inv. 1: --list-axes is a pure read-only probe (short-circuits before
run_blueprint_sweep; builds the wrapped composite, reads param_space, prints
— no run, no seed, no engine execution).
- Behaviour-preserving single-source: blueprint_axis_probe is token-identical to
the two former inline probes; three copies (sweep/mc/list) collapse to one; the
reload closures survive (topology_hash + per-member run); clippy -D warnings
clean, no dead code; the subsumed tests
(blueprint_sweep_member_equals_single_run_and_shares_topology_hash,
blueprint_mc_family_rejects_an_open_blueprint) stayed green.
- The blueprint_axis_probe .expect is not a latent panic: the ["sweep",..] arm
validates blueprint_from_json first (exit 2), pinned by the shipped
aura_sweep_list_axes_rejects_malformed_blueprint E2E (no panic).
Ledger: refreshed the C24 realization block (docs/design/INDEX.md) — reclassified
the "axis-name discovery surface" from tracked debt to shipped (cycle 0096),
recording the single-sourced blueprint_axis_probe and the listed==swept-by-
construction property. Per-member trace-writing (#168) remains the one tracked
debt in that block.
Milestone World/C21 stays OPEN — the walk-forward half (#173, IS-refit, now
unblocked by this #169) remains. Ephemeral spec/plan git-rm'd per the lifecycle
convention.
refs #169
One iteration, three tasks: (1) extract blueprint_axis_probe and subsume the
two existing inline copies of the wrapped-namespace probe
(blueprint_sweep_family + blueprint_mc_family) into it — the single source the
spec's rationale requires; (2) the --list-axes surface (SweepBlueprintArgs
field, valueless-flag parse + standalone guard, list_blueprint_axes, dispatch
short-circuit); (3) four E2Es (open lists prefixed names, closed empty,
combined-flags reject, malformed-blueprint safety — no panic).
refs #169
Architect drift review (scope cec7811..HEAD, the sole gate — no regression
script) returned drift-clean with positive What-holds:
- invariants 8/9: the whole cycle is aura-cli (main.rs + cli_run.rs + ephemeral
docs); nothing entered aura-engine/aura-registry; FamilyKind::MonteCarlo,
monte_carlo, append_family, mc_member_reports are pre-existing seams reused.
- invariant 1 / C1: draws run disjoint-parallel via the engine monte_carlo seam
(seed-input order, no within-sim concurrency); bit-identity proven by the
reproduce round-trip (unit + E2E).
- the C1 lockstep is a single shared fn: synthetic_walk_sources (one fixed
SyntheticSpec) is called by BOTH the persist path and the reproduce MonteCarlo
branch; pip is lockstepped too (both pass DataSource::Synthetic).
- the sweep-sibling pattern matches: Result<McFamily,String> + boundary render.
- scope honesty: WF deferral (#173, dep #169) and synthetic-walk-DGP (#172) are
named in the spec + feat body, not silent.
Carry-on debt (does NOT block close, filed forward, NOT new-this-cycle drift):
synthetic_walk_sources' len:60 is hand-calibrated to the shallow stage1 warm-up;
a deep-lookback closed blueprint warms poorly -> silent-vacuous draws with no
error, and the anti-degenerate test only exercises the shallow fixture. Folded
into #172 (real-data DGP retires the length calibration) per the architect's
recommendation, rather than a new thread.
Ledger refreshed: the C21 realization block now records the MC verb shipped
(cycle 0095) with WF deferred; the C18 reproduction block notes aura reproduce
now spans FamilyKind::MonteCarlo.
Verified green (orchestrator, this session): cargo build --workspace clean;
cargo clippy --workspace --all-targets -- -D warnings clean; cargo test
--workspace green. Cycle is drift-clean (not a milestone close — #170's WF half
remains, milestone stays open).
refs #170
4 tasks: parse_mc_blueprint_args, blueprint_mc_family (closed-blueprint
guard + seed-driven synthetic walks), the reproduce MonteCarlo realization
branch, and run_blueprint_mc + the .json dispatch arm + E2E. All in
aura-cli/main.rs (engine/registry untouched).
Architect drift review (4751d4b..HEAD): drift_found — ledger-currency only; the
code is clean.
What holds (architect, confirmed by diff + green tests):
- Inv 8 / C9: aura-engine byte-untouched; content_id + sha2 in aura-cli, the
store in aura-registry.
- Inv 9: Registry::{put,get}_blueprint is a dumb bytes-by-key store (opaque
String keyed by String hash; no sha2, no parse, no sha256==hash verify — the
caller owns the hash). No domain knowledge crept into the engine or registry.
- C1: the run_blueprint_member extraction is behaviour-preserving (keystone
blueprint_sweep_member_equals_single_run_and_shares_topology_hash unchanged +
green); serde_json/float_roundtrip serves determinism (disk==recomputed), not a
mask (1-ULP canary green).
- C11/C12: one blueprint stored per family, keyed by the shared topology_hash.
Resolutions:
- [ledger] Refreshed C18 + C24: added the cycle-0094 Realization (the
content-addressed store runs/blueprints/<hash>.json + aura reproduce), and
retired the now-false "content-addressed identity / full reproduction deferred"
claims (INDEX.md:1261, C24 deferred block). Only the structural-axis /
whole-harness content-id (and the debug-name-in-id question) genuinely remains,
filed forward (#171, #170).
- [debt->closed] Added the two untested refuse-don't-guess E2E arms
(aura_reproduce_rejects_a_non_generated_family — a hard-wired sweep member has
no topology_hash; aura_reproduce_rejects_a_missing_stored_blueprint — the store
was deleted), and a cross-surface unit pin
(topology_hash_is_the_content_id_of_the_canonical_form) so the two acc-1 paths
cannot silently drift.
- [scaling] MC/walk-forward-from-blueprint (#170) will need the same put_blueprint
hook or reproduce won't cover them — noted on #170.
No regression scripts in this project (Test is the gate): full workspace suite
green (51 suites), clippy -D warnings clean, binary verified end-to-end.
Ephemeral spec/plan git-rm'd per the lifecycle convention; durable rationale is in
the ledger. The World/C21 milestone stays open (#170 remains).
closes#158
Iteration 1 (acceptance 2, the heart): the content-addressed blueprint store
(Registry::put_blueprint/get_blueprint under runs/blueprints/), the store write
at the sweep persist seam, the extracted shared run_blueprint_member, and
`aura reproduce <family-id>` re-deriving every persisted member bit-identically
from the stored blueprint. acceptance 1 (graph introspect --content-id) and 3
(Tier-1 id stability) deferred to plan 0094b.
refs #158
Cycle-close drift review (architect) for cycle 0093 / #166 (aura sweep
<blueprint.json>). Drift-found on debt only; no contract violation.
What holds (architect, evidence of review): invariant 9 fail-clean (resolve_axes
runs before the sweep closure → named BindError UnknownKnob/MissingKnob/KindMismatch,
exit 2; UnknownNodeType on load; no registry); C1/C12/C18 shape verbatim from
stage1_r_sweep_family (members disjoint + enumeration-ordered; shared topology_hash
correct, consistent with the cycle-1 #158 signal-only scope; append_family/
sweep_member_reports reused); reload-per-member is sound (Composite !Clone, #164);
stdout uses family_member_line with family_id, run_sweep-consistent.
Resolved: ledger refreshed (C24 Status — the cycle-0093 realization: the World now
orchestrates FAMILIES from blueprint-data; the open-vs-bound fixture fact + the
reload-per-member rationale recorded). Drift filed forward: #168 (--trace writes no
per-member traces — silently like --name, debt-med), #169 (no axis-name discovery
for loaded sweeps, debt-low), #170 (MC/walk-forward over a loaded blueprint — the
next family-verb cycle, assigned to the milestone).
Ephemeral 0093 spec + plan git-rm'd per the lifecycle convention.
closes#166
Three-task decomposition of #166 (sweep a loaded blueprint): the parser
(parse_sweep_blueprint_args + SweepBlueprintArgs + --axis i64-then-f64 lexing),
the member-build (run_blueprint_sweep — a structural mirror of stage1_r_sweep_family
with three deviations: by-name axes, reload-per-member since Composite is !Clone,
per-member topology_hash) + the .json dispatch arm, and the tests (grammar +
equivalence-vs-run_signal_stage1r + the binary sweep-family E2E + unknown-axis
fail-clean). Purely additive; reuses the engine sweep machinery + cycle-1's
wrap_stage1r unchanged. Grounding decisions (Q1-Q5) recorded on #166.
refs #166
Cycle-close drift review (architect) for cycle 0092 / #165 (aura run
<blueprint.json>). Drift-found on ledger currency only; the code is clean and
correct.
What holds (architect, evidence of review): the stage1_signal/wrap_stage1r split
is behaviour-preserving (golden metrics byte-unchanged; loaded_signal bit-identical
green; the STAGE1_R_SMA_* constants keep the hashed signal == the executed signal);
sha2 + the topology_hash helper live in aura-cli only, aura-engine stays sha2-free
(invariant 8 / C16); the resolver resolves the closed std_vocabulary set, unknown
type -> UnknownNodeType, no registry (invariant 9); topology_hash is a correct
Tier-1 optional and the RunManifest <-> RunManifestRead read-mirror both carry it.
Resolved: ledger refreshed (C24 Status — the cycle-0092 run-from-blueprint
realization + the topology_hash #158 anchor landing; #158 reframed from "premature"
to "field landed, full reproduction remains"). Drift filed forward: #167
(single-source the stage1-r suffix-remapping lockstep — debt-med), and a scope note
on #158 (the hash currently covers the signal only; a structural-variant content-id
is the #158/#166 concern). The spec's illustrative instrument:"GER40" example
(note-low) is moot — the ephemeral spec is removed here.
Ephemeral 0092 spec + 0092/0092b plans git-rm'd per the lifecycle convention.
closes#165
The remaining Tasks 4-5 of #165 after the ff4a1b3 infrastructure (restructure +
topology_hash + the shared run_signal_stage1r seam): the `aura run
<blueprint.json>` CLI arm (wiring the committed seam, retiring its transient
dead_code allow) + the loaded-signal bit-identical / determinism / E2E tests +
the in-repo demo blueprint. Resolves the Task-4 block by dropping the
consumer-less --pip-size flag (pip is data-derived).
refs #165
Five-task decomposition of #165 (run a serialized signal blueprint):
1. behaviour-preserving restructure of stage1_r_graph into stage1_signal() +
wrap_stage1r() (the serializable signal boundary + the shared wrapping),
gated by the stage1-r + bit-identical-e2e tests staying green;
2. RunManifest.topology_hash (Tier-1 optional) + thread None into the ~24
workspace literal sites (one compile-gate);
3. the shared run_signal_stage1r seam + the sha256_hex helper (sha2 in aura-cli,
off the frozen engine, invariant 8) + run_stage1_r gains its topology_hash;
4. the `aura run <blueprint.json>` CLI arm (.json discriminator, --params cells),
leaving the existing harness-kind dispatch intact (#159 stays);
5. demo signal blueprint + the bit-identical / determinism / E2E tests.
Tasks 1-2 (restructure + field-add) run and verify first. Derived grounding
decisions (the restructure target, param_space-derived manifest.params, the Q4
behaviour-preserving semantics) recorded on #165.

Closes the cycle-0090 (#156) work and delivers the "Topology-as-data:
blueprint serialization & loader (C24)" milestone.
Cycle-0090 audit (architect drift review, range 7ad7f58..HEAD): drift-clean
on substance. Tier-1 forward-tolerance is genuinely serde-default
(deny_unknown_fields = 0 in every production struct), pinned at envelope +
primitive across both the in-crate and public-seam tests; Tier-2 refusals
real and green; no struct/signature/runtime change; the invariant-5
acyclicity lockstep (construction gate <-> bootstrap Kahn sort) undisturbed;
invariant-9 resolver stays injected, no registry. The one medium item the
architect flagged — the C24 Remaining block carried no deferral signal for
#158/#159 — is fixed in this commit's ledger update.
Milestone fieldtest (fieldtests/milestone-topology-as-data/, the close-gate
evidence): GREEN, 0 behavioural bugs. A downstream consumer ran the full
author -> serialize -> load -> construct -> introspect -> reproduce story from
the public surface alone — round-trip bit-exact on both authoring surfaces
(Rust builder + op-script CLI), build-free introspection, Tier-1/Tier-2
forward-compat by name, fail-fast diagnostics by identifier. Verified the
headline claims myself (the two Rust binaries + the CLI build/diff + the
fail-fast exits), not just the agent's report.
Findings triaged to the forward queue (none blocking): op-script grammar
undocumented + a stale cycle-0088 example (#163); canonical trailing-newline
divergence + Composite Debug/PartialEq ergonomics (#164); CLI discoverability
of build/introspect + no `graph run` (commented on #159); the newline as a
content-addressing prerequisite (commented on #158).
#158 (content-address topology in the manifest) and #159 (retire the
hard-wired harnesses) were moved OUT of this milestone: both are premature
until the World generates runs from blueprint-data (commit still fully
identifies every hard-wired topology), so they belong to the
project-as-crate / World cycle. The C24 ledger Status records the delivery
and the deferral.
Ephemeral cycle-0090 spec + plan removed per the lifecycle convention.
The Gitea milestone container is closed on user ratification (this run
tees up the close, does not click it).
Single-task iteration for #156: append the Tier-1 forward-tolerance
characterization test (unknown_optional_field_is_tolerated_byte_identically),
reword the LoadError::UnsupportedVersion doc to the settled two-tier
discipline, and codify it in the C24 ledger (Status sentence + drop #156 from
Remaining). No struct/signature/runtime change. refs #156
Cycle-close audit for the /boss run that followed up the cycle-0088 construction
fieldtest (#161 cycle-reject + #162 diagnostics-by-identifier). Regression gate:
full workspace suite green (0 failed).
Architect drift review (range 86841b0..HEAD): drift_found, two items, both
documentation-side — the code is correct and green.
- What holds: invariant 5 / C9 acyclicity (closes_cycle is a correct eager
reachability gate, no false positive on a valid DAG); C24 no-second-validator
(blueprint.rs untouched, finish() only translates the gates' returned
CompileError); fieldtest corpus handled per convention.
- Resolved (fix path, ledger): the C24 Status now enumerates the #161 eager
acyclicity gate and captures the LOCKSTEP the architect flagged — closes_cycle
(construction-time) and the bootstrap Kahn sort (harness.rs, BootstrapError::Cycle)
are now two homes of invariant-5 that must co-evolve when the explicit
delay/register node lands; plus a note that the holistic finalize faults now read
by-identifier (#162) while still calling the unchanged gates.
Ephemeral 0089 spec + plan git-rm'd per the active-cycle artefact lifecycle; the
durable rationale is lifted to the ledger above. No code change in this commit.
Two tasks: item 1 (by-identifier finalize) lands atomically across both crates —
three OpError variants + finish() translation + the CLI presenter arms + five test
touches (two of them E2E twins plan-recon found that the spec's testing strategy
under-enumerated: construction_e2e.rs and tests/graph_construct.rs); items 2 & 3
(bind-mismatch prose + discoverable bind form) are additive CLI changes.
Architect drift review of cycle 0088 (#157, the introspectable fail-fast
construction service: §A shared gate predicates, §B the GraphSession/Op/replay
per-op surface + introspection, §C the aura graph build/introspect CLI).
What holds (confirmed against the diff): no-second-validator (C24) — edge_kind_check
is the single kind-check site called by both validate_wiring and
GraphSession::connect, and validate_wiring / check_param_namespace_injective are
reused verbatim in finish(); engine domain-free (invariant 9) — construction takes an
injected Fn(&str)->Option<PrimitiveBuilder>, no registry, the closed match +
std_vocabulary_types live in aura-std; topology-as-data / no DSL (C24/C17/inv 10) —
the engine Op is serde-free, the OpDoc wire DTO is CLI-side, ops are static and
non-Turing-complete; replay-equals-builder byte-identity (construction_e2e.rs) protects
C9/C19/C23.
Resolution:
- fix (drift-med): the root-role-boundness gate was the one holistic check finish()
re-implemented instead of sharing — extracted check_root_roles_bound (blueprint.rs)
and called from BOTH compile_with_cells and finish(), so finish() now reuses ALL the
holistic gates and the no-second-validator claim is literally true. Behaviour-
preserving (same UnboundRootRole variant; unbound_root_role_is_rejected stays green).
- fix (drift-med): removed the #![allow(dead_code)] on construction.rs — empirically
unnecessary (the pub re-exported surface is reachable; clippy -D warnings green
without it) — and its now-inaccurate comment (it claimed removal "when the consumer
lands", but the consumer is a separate crate). Also tidied a stale graph_construct.rs
module-doc line.
- fix (ledger): C24 Status refreshed — #157 moved out of "Remaining" with a cycle-0088
realization note (the construction service: eager/holistic gate split, build-free
introspection, emits the #155 blueprint); #159 reframed as paired with #157.
- carry-on (debt-med, forward-noted): the std_vocabulary roster is now a third hand-kept
copy (match + test list + std_vocabulary_types) and introspect --vocabulary escalates
#160's gap to user-facing — noted on #160; still fails safe.
- carry-on (scaling-low, forward-noted): the engine Op -> wire OpDoc direction is
unguarded for future Op variants — noted on #156 (the format-extension track).
No architect-sweep / regression script is declared in the project facts, so the suite
is the gate: cargo test --workspace 51 suites green; clippy --all-targets -D warnings
clean. Cycle drift-clean.
Ephemeral cycle artifacts removed (lifecycle convention): docs/specs/0088-*,
docs/plans/0088-*.
closes#157
Iteration-2 tasks (9-12) appended to the cycle-0088 plan: the JSON op-list serde
DTO (CLI-side, engine Op stays serde-free), `aura graph build` (replay -> emit
#155 / fail fast at op N), `aura graph introspect` (--vocabulary / --node /
--unwired), and an E2E suite driving the aura binary. All changes in aura-cli;
the engine core (ea1ca32 + 27ac4dc) is consumed unchanged. Wire-format forks
derived + recorded on #157.
refs #157
Iteration-1 §A of the construction service (#157): the surface-agnostic shared
predicates the eager op-script path and the holistic finalize gates both call —
no second validator (C24).
- edge_kind_check (blueprint.rs): the per-edge producer/consumer kind check,
lifted verbatim out of validate_wiring's edge loop into a pub(crate) fn that
validate_wiring now calls — behaviour-preserving (same Bootstrap(KindMismatch)
variant; the existing compile-time gate test stays green).
- resolve_input_slot / resolve_output_field (builder.rs): the exactly-one-match
name→index resolution extracted as pub(crate) fns over (&NodeSchema, &str), so
the runtime-String op-script names share GraphBuilder's resolution; GraphBuilder
delegates and maps to the unchanged BuildError variants.
- try_bind + BindOpError (aura-core node.rs): the fallible Result twin of bind
(bind keeps its panic contract and pinned messages verbatim; try_bind is a
separate method reporting the same three conditions as values).
- check_param_namespace_injective + validate_wiring widened to pub(crate) for the
finalize-stage reuse by the upcoming GraphSession::finish (§B).
Partial iteration: §B (the GraphSession/Op/replay surface + introspection) and
the §A→§B integration land next (plan Tasks 4-8). compile_with_params /
check_ports_connected are behaviourally unchanged. Full suite green; clippy clean.
Plan correction folded in: Task 3's test originally referenced aura_std::Sma —
infeasible inside aura-core (aura-std depends on aura-core; the reverse edge is a
dependency cycle). Adapted to a local PrimitiveBuilder probe with identical
assertions.
refs #157
Iteration-1 plan for #157 §A+§B: the eager/holistic gate split (extract
edge_kind_check + shared name-resolution helpers + try_bind, all reusing the
engine's gates — no second validator), the GraphSession/Op/replay per-op
surface, build-free unwired/vocabulary introspection, and the acceptance-1
replay-equals-GraphBuilder compile-identity test. The JSON op-list + CLI are
iteration 2. Eight RED-first tasks; struct literals + filter strings verified
against the current tree.

Architect drift review of cycle 0087 (#155, the C24 blueprint-serialization-and-
loader first cut). What holds (confirmed against the diff): C17 / no-RustAst (the
format carries only type identity + name + bound params + topology; the build
closure is dropped and re-derived, no node logic in the data); invariant 9 /
domain-free engine (injected resolver, the closed match in aura-std, engine lib
deps aura-core + aura-analysis only — a compiled-in closed set, not a dynamic
registry); C9 round-trip / C23 bootstrap untouched (loader's terminal step is the
unchanged Composite::new -> bootstrap_with_params; validation deferred to the
existing gate, not bypassed).
Resolution:
- fix (ledger): C24 Status refreshed from "unbuilt" to "first cut shipped"
with a cycle-0087 realization note; C9's round-trips-both-ways refinement
marked realised. The ledger no longer contradicts the code.
- backlog (debt-med): the hand-written std_vocabulary match has no guard test
that fails when a new zero-arg aura-std node lacks an arm — fails safe today
(clean UnknownNodeType, never silent-wrong). Filed as #160.
- carry-on (scaling): construction-arg builders + sinks excluded, so no real
harness round-trips yet; harness retirement blocks on the construction +
project-as-crate layers — already tracked #156/#157/#159.
No architect-sweep / regression script is declared in the project facts, so the
suite is the gate: cargo test --workspace 748 passed (737 -> 748 = the 11 new
tests); clippy --all-targets -D warnings clean.
Ephemeral cycle artifacts removed (lifecycle convention): docs/specs/0087-*,
docs/plans/0087-*.
Five tasks for #155: serde derives on the serialized plain types; the closed
aura-std std_vocabulary resolver (22 zero-arg builders); the DTO layer +
canonical serializer + format_version envelope; the resolver-injected loader +
typed LoadError; and the round-trip tests (canonical golden, named failures,
bit-identical run vs Rust twin, idempotence, recursion).
refs #155
Architect drift review (8d04a84..HEAD): clean, no drift/debt.
What holds (verified against code, not asserted):
- C10 cost contract preserved: the non-R-harness guard reads the *resolved*
harness, so a `run` cost flag on sma/macd (incl. the implicit default) is
exit-2 fail-loud, never a silent no-op; parse_nonneg_rate names the flag;
the eight stage1-r cost goldens are byte-unchanged.
- The three edited realization notes are grounded: C12 Arc-sharing →
aura-ingest/src/lib.rs:316; aura-std "~30 modules" → 30 node files;
C15 Session emits only bars_since_open, matching the quoted source wording.
- project-layout.md rewrite complete: no residual exposure/realistic-broker.
Non-actionable scaling note (architect): the guard hardcodes Stage1R as the
sole R-harness, coupled to the "stage1-r only" note text — three sites move
together if a second R-harness ever lands; not in plausible next scope.
Regression gate: cargo test --workspace exit 0 (48 binaries, 737 passed, 0
failed); cargo clippy --workspace --all-targets -- -D warnings exit 0. No
baseline moved → no ratify needed. cycle 0086 tidy (clean).
Ephemeral spec/plan (docs/specs/0086, docs/plans/0086) removed per the
ephemeral-artifact convention.
Four tasks from spec 0086: (1) named non-negativity diagnostic via a
parse_nonneg_rate helper + perturbed-test fix; (2) non-R-harness guard
(the spec_gap, reject/exit-2); (3) COST_FLAGS_NOTE appended to the usage
+ --help surfaces; (4) the C10 ledger note + full-suite/clippy gate.
Confined to crates/aura-cli; the eight stage1-r cost goldens stay byte-green.

Cycle 5 of milestone #148 (per-cycle-held accrual + CarryCost). Architect drift
review over 39f9387..f5e00a9: status clean, no code drift.
What holds (architect, evidence-of-review):
- C11 byte-identity: the AtClose eval arm is the pre-cycle-5 tokens verbatim
(if closed { per } / if open { per }, the per + cum lines unchanged), so the
cycle-0083/0084 net_expectancy_r goldens (-614.3134020253314, -615.0304388396047)
stay byte-identical and the AtClose unit regressions are untouched.
- Accrual sound, no double-count: aura-analysis (summarize_r) is genuinely unchanged.
During a hold the carry lives only in open_cost_in_r (cum=0); at close it moves to
cum while open_cost->0 (open/closed mutually exclusive per cycle), so net_r_equity
subtracts cum+open singly. summarize_r reads the close-row dumped total + the
window-end accrued-so-far — one charge per trade, acc reset proven. The 3-field
cost record's semantics generalize cleanly to accrual.
- C9/C16/C23: the diff touches only aura-std + aura-cli; aura-engine stays
domain-free. CarryCost is a CostNode factor, CostRunner a plain Node, composed via
cost_graph/CostSum. label() carries its param. All three run_stage1_r call sites
threaded; the negative-rate guard is symmetric with the sibling cost flags.
Resolved this commit (the cycle-close ledger sync):
- C10 realization note (cycle 0085) added under docs/design/INDEX.md — C10's
"per-cycle-held factors accrue over the hold" clause is now first realized (the
prior 0084 note covered the cost-graph composite-builder).
Regression gate: cargo test --workspace (0 failures), cargo build --workspace, cargo
clippy --workspace --all-targets -- -D warnings clean — the architect is the primary
gate (no dedicated regression script). Ephemera (spec 0085 + plan 0085) git rm'd.
Milestone "Cost-model graph (in R)" remains OPEN.

summarize_r and the CLI net_eq wiring are UNCHANGED; the cycle-0083/0084 goldens are
the byte-identity regression net.

Cycle 4 of milestone #148 (cost-graph composite-builder). Architect drift review
over fc52b4f..d5c44dd: drift_found, every item dispositioned.
What holds (architect, evidence-of-review): C16/C9 — cost_graph lives in
aura-composites, the factors in aura-std, aura-engine stays domain-free; the
composite is ordinary downstream nodes. C11 behaviour-preservation is structural,
not just asserted — the composite inlines to the same flat fan-in as the deleted
CLI block (identical node set/order, cost[k].field slot map, geometry fan, net_eq
terms/signs, cost_rec cols), so the cycle-0083 net_expectancy_r goldens stay
byte-identical. C23 — role/port names non-load-bearing; 4 fixtures pin the role-set
+ output triple.
Resolved this commit:
- [high] ledger C10: the cycle-0083 note's "Still deferred (decision E)" is removed
(E shipped this cycle) and a cycle-0084 realization note added.
- [medium] cost_graph .leak() provenance (aura-composites/src/lib.rs): the
"risk_executor precedent" was imprecise — that .leak() lives in risk_executor's
TEST (one-shot, leak-safe), not its production builder. Doc corrected: the leak is
fine for one-shot run-path construction but must be interned (the COL_PORTS
production pattern) before cost reaches the sweep path.
- [low] cli_run.rs golden docstring cited the deleted `slot * COST_WIDTH + f` CLI
wiring; updated to the cost_graph composite's per-node cost[k].<port> wiring.
Deferred (tracked, not pending) -> #152:
- [medium] the cost[k].<port> index-namespacing restated across CostSum / cost_graph
/ the CLI (a build-validated lockstep — a divergent name fails loudly at g.build(),
NOT the silent positional kind 0083 collapsed), AND the per-build .leak() that
becomes an allocation regression on the per-member sweep path. Both are harmless on
the current run-only cost path; the proper fix is one sweep-safe single-source
cost-port-name contract (interned), best built with the deferred sweep-cost cycle.
Regression gate: cargo test --workspace (0 failures), clippy --workspace --all-targets
-- -D warnings clean, cargo doc clean — the architect is the primary gate (no dedicated
regression script). Ephemera (spec 0084 + plan 0084) git rm'd.
Milestone "Cost-model graph (in R)" remains OPEN.
refs #148
Two tasks: (1) the cost_graph(Vec<PrimitiveBuilder>) -> Composite builder in
aura-composites + the GEOMETRY_WIDTH re-export from aura-std + two unit tests
pinning the exposed input-role set and the 3-field output; (2) the aura-cli
stage1_r_graph rewire onto cost_graph, deleting MAX_RUN_COST_NODES and
COST_SUM_PORTS. Runtime port names .leak()'d (the risk_executor precedent).
Behaviour-preserving: the cycle-3 net_expectancy_r goldens are the regression net.
refs #148
Architect drift review over 6c7f5dd..HEAD. No regression scripts in this project
→ the architect is the sole gate; verdict: shipped code byte-clean.
What holds (verified against the diff):
- C9 — a CostRunner<F> is a plain downstream Node; the two cost nodes are thin
factors wired through the same cost_node_builder. No runtime sub-object.
- C18 / byte-identity — the numerator/latched token form is preserved verbatim;
the two new CLI goldens pin exact net_expectancy_r and pass; the no-cost golden
is untouched.
- C10 co-temporality + C23 + invariant-4 — the gate-on-PM-geometry-only rule
(cold factor input → 0 cost, row still emits) is now centralized once in the
runner; name() dropped cleanly (label() remains the non-load-bearing symbol);
the 3-field triple is a single source (COST_FIELD_NAMES) read by both producers
+ CostSum + the CLI — the cycle-0082 by-convention lockstep is structurally gone.
Resolution:
- [fix] docs/design/INDEX.md C10 — added the cycle-0083 realization note (each
prior cost cycle got one; the deferred general CostNode trait is now shipped and
the lockstep eliminated). Ledger deferred-work tracking re-synced.
- [fix] crates/aura-std/src/lib.rs:5 — module doc now names the CostNode/CostRunner
authoring surface.
- [carry-on, low debt] vol_slippage_cost.rs still declares its extra-input port
twice (the cost_node_builder arg and the trait extra_inputs()); a clean unifier
needs design thought (builder() is static, no factor instance) and is not worth
forcing at cycle close. Documented here; agreement rests on the helper + a test +
the harness debug-assert.
Cycle 0083 ephemera removed (docs/specs/0083 + docs/plans/0083).
Verified: cargo build/test --workspace clean (0 failures), clippy -D warnings
clean, cargo doc -p aura-std clean (CostNode/CostRunner intra-doc links resolve).
refs #148
Cycle 0082 (cost-graph composition, cycle 2) closes drift-clean against C10. The
architect review confirms the cycle is fundamentally sound:
What holds: VolSlippageCost + CostSum are ordinary aura-std downstream nodes
(C9/C8), cost stays out of aura-engine; the vol proxy is a trailing realized range
(C2, no look-ahead); feed-forward, no equity feedback (C1); the co-temporality
contract (gate cost nodes on PM geometry only, 0-cost on a cold state input) is
consistent with C1/C2/C9 and the cycle-1 positional join, and charging 0 during
warm-up is honest (no estimate yet, not a fabricated guess). The no-cost C18 golden
is byte-identical.
Drift resolved at close:
- [medium -> fixed] docs/design/INDEX.md (C10): added the cycle-0082 realization
note. The load-bearing co-temporality contract (generalizes to all future cost
factors) lived only in code comments + spec 0082; the ledger is now its durable
home once the spec is removed.
- [low -> fixed] crates/aura-cli/src/main.rs: --cost-per-trade now rejects negatives
at parse, symmetric with --slip-vol-mult (it previously deferred to the node
assert's panic). Run-path tests + the no-cost golden stay green.
Carry-on (documented deferrals, not this cycle's debt to fix):
- The 3-field cost triple {cost_in_r, cum_cost_in_r, open_cost_in_r} is restated
by-convention across ConstantCost, VolSlippageCost, and CostSum (compiler-unlinked
lockstep) — to be unified by the general CostNode trait, now justified by two
concrete nodes (#148).
- SLIP_VOL_LENGTH=5 is sized to warm within the synthetic smoke fixture; documented
in the const doc (on real M1 data any reasonable window warms).
- A future per-cycle-held accrual (carry/funding) accrues over holding duration,
which will force a summarize_r fold change and stress the positional seam — flagged
for that deferred cycle.
Regression gate green and unchanged: full workspace suite 0-fail, clippy --workspace
--all-targets -D warnings clean. No baseline moved -> no ratify.
Spec + plan ephemera removed (git rm docs/specs/0082, docs/plans/0082).
refs #148
Cycle 2 of the "Cost-model graph (in R)" milestone (#148): the milestone's real
architectural claim — the cost graph composes. Two cost nodes now sum into one
net-R curve while summarize_r and the net_r_equity tap stay structurally
unchanged.
- VolSlippageCost (aura-std): a second, STATE-DEPENDENT cost node; per-trade
charge = slip_vol_mult * volatility / |entry-stop|, in R. The vol is an
independent short-horizon realized range (SLIP_VOL_LENGTH=5, distinct from the
stop's EWMA-3) — scaling slippage by the stop's own vol would collapse cost-in-R
to a constant (indistinguishable from ConstantCost).
- CostSum (aura-std): the cost-graph OUTPUT node — sums N cost nodes' 3-field
cost-in-R records per-field into one aggregate. summarize_r and net_r_equity
read the aggregate (one home for cost; n=1 is the identity, so the cost path is
uniform). A future CostNode trait (deferred) will unify the cost-triple the two
producer nodes currently restate by-convention.
- Run path: --cost-per-trade and --slip-vol-mult combine, their costs summing into
the net-R curve; a hoisted vol proxy (RollingMax-RollingMin) keeps the single
feed. Run-path-scoped; sweep/walkforward/mc pass None.
Co-temporality contract (the load-bearing design decision; corrected from the
signed spec after the implement-loop correctly BLOCKED Task 3 on it). summarize_r
positional-joins cost[i] <-> record[i], so the cost stream must be co-temporal
1:1 with the PM record. A cost node is therefore gated ONLY by the PM geometry
(closed/open/entry/stop); a not-yet-warm state input (the vol proxy warms later
than PM) contributes 0 cost that cycle rather than withholding and desyncing the
stream. This makes co-temporality structural + warmup-independent, preserves the
C18 golden, and generalizes to any future cost factor. The rejected alternative
(a key-join in summarize_r) would have moved the golden and pushed cost-graph
logic into the post-run fold. Recorded on #148.
Tests: VolSlippageCost + CostSum unit sets (incl. the co-temporal-zero-during-
warmup case); the CLI composition run (both flags -> net_both < net_flat,
net_r_equity persisted); node-level EXACT additive composition (net_both ==
net_flat + net_vol - gross over the real nodes), the aggregate net_r_equity ==
post-run net total, and CostSum(1) identity. Full workspace suite green; clippy
-D warnings clean; the no-cost C18 golden byte-identical (the regression floor).
Deferred (later cycles of this milestone): the general CostNode trait + cost-graph
composite-builder (now justified by two concrete nodes), the conviction-weighting
R-aggregation axis, and cost on the reduce-mode sweep path. Spec + plan amended to
the corrected contract; both are cycle ephemera (git rm at cycle close).
refs #148
Task-by-task plan for spec 0082: the VolSlippageCost node (Task 1) and the
CostSum aggregator (Task 2) in aura-std; the run-path wiring as one compile-gate
task (Task 3) — stage1_r_graph cost-param widening + vol-proxy hoist + the
CostSum-aggregated cost block + the --slip-vol-mult thread-through across all
call sites, with a CLI composition test and the no-cost golden floor; and the
node-level exact-sum composition tests (Task 4). RED-first per task. The
&'static str CostSum port names are interned (COST_SUM_PORTS, mirroring
COL_PORTS); summarize_r is unchanged (it folds the CostSum aggregate).
refs #148
Cycle 0081 (cost-model graph, cycle 1) closes drift-clean against C10: the
architect review confirmed ConstantCost + the net-R seam realize the contract
at its floor (C9 cost node; net_r_equity a C8/C18 sink; R-pure; one home for
cost, subsuming the retired scalar round_trip_cost; pure feed-forward C1), and
the no-cost baseline is byte-identical (C18 golden held). Regression gate green
and unchanged: full workspace suite 0-fail, clippy --workspace --all-targets
-D warnings clean. No baseline moved -> no ratify.
Ledger sync (docs/design/INDEX.md): added the C10 cycle-0081 realization note
(ConstantCost node + net_r_equity seam shipped; scalar round_trip_cost retired;
run-path-scoped; later-cycle deferrals named).
Drift swept (cycle-adjacent + cheap one-liners):
- crates/aura-analysis/src/lib.rs net_expectancy_r doc: the removed in-fold
mechanic (mean(R - round_trip_cost/latched_dist)) -> the cost-stream fold.
- crates/aura-std/src/lib.rs module doc: "realistic broker profiles" (retired
by #116) -> the legacy SimBroker pip yardstick + cost-model nodes.
Backlogged (pre-existing, broader, predates this cycle): the
docs/project-layout.md backtest worked example is stale on #117 (exposure->bias)
and #116 (realistic broker); a proper rewrite is filed as #151, not folded here.
Architect-accepted: the #[allow(dead_code)] on r_col::ENTRY_PRICE/STOP_PRICE
(their production reader legitimately removed when summarize_r stopped recovering
latched_dist; still the layout contract + exercised by test fixtures).
Spec + plan ephemera removed (git rm docs/specs/0081, docs/plans/0081).
refs #148
Task-by-task plan for spec 0081: the ConstantCost node (aura-std), the
summarize_r scalar->cost-stream change (the workspace-wide call-site
migration as one compile-gate task), and the run-path wiring (net_r_equity
tap + --cost-per-trade) — RED-first per task. Scoped to the run path
(non-reduce); sweep/walkforward/mc pass None this cycle.
refs #148
Architect drift review (d50a482..feat): drift_found — documentation only,
NO contract violation. C1/C9/C10/C23 verified preserved against the diff:
`generalization` is a pure deterministic fold (registry-side, C9; R-only,
C10); the sole `instrument = Some` production site is `run_generalize`, every
other manifest constructor threads `None` + `skip_serializing_if`, so
sweep/mc/walkforward/standalone manifest bytes are byte-identical (C23); the
compat read-mirror was threaded in lockstep.
Drift fixed in this commit (ledger sync, docs/design/INDEX.md):
- The inferential-honesty thread read "now two of three pieces built" / "#146
remains the last open piece" — false now that #146 landed. Updated to record
the inferential half as structurally complete (all three built, cycle 0078)
+ the #146 realization, including the aggregator/validator-vs-selector
distinction (#146 is a recomputable aggregate, not a FamilySelection
annotation).
- C18 realization block: added the cycle-0078 note — the comparison axis (C12)
realized as FamilyKind::CrossInstrument + the first-class RunManifest.instrument
lineage field.
Regression: no regression scripts configured (project facts name only
Build/Test/Lint/Doc); architect is the gate. cargo test --workspace green
(0 failed) and cargo clippy --workspace --all-targets -D warnings clean,
orchestrator-verified.
Ephemera removed per the project lifecycle convention: docs/specs/0078-* and
docs/plans/0078-* (git rm). Durable rationale lifted to the ledger above.
refs #146
Three tasks for #146: (1) RunManifest.instrument serde-widened field +
compat-mirror lockstep + thread all in-workspace literals + back-compat tests;
(2) aura-registry FamilyKind::CrossInstrument + the R-only generalization
reduction (worst-case floor + sign-agreement + breakdown) + check_r_metric +
two RegistryError variants; (3) aura-cli generalize subcommand (single-cell
stage1-r candidate x instrument list), data-free arity/metric refusals, a
gated-skip cross-instrument E2E.
fieldtests/ confirmed outside the workspace compile set; FamilyKind has no
exhaustive match (serde-derive); only RegistryError's Display match is a gate.

Architect drift review over 9c6b9c7..cb32658 returned drift_found (3 items);
all resolved here. What holds (architect): C23 default-argmax byte-identical,
C9 separation (selector in aura-registry, walk_forward selection-agnostic),
C1/C2 (plateau pure/deterministic/in-sample), one higher_is_better direction
source.
Resolutions:
- [medium] Backfilled the pre-0077 FamilySelection legacy-load fixture
(report.rs family_selection_loads_a_pre_0077_legacy_line). The feat commit
and the struct doc-comment claimed "a legacy line still loads (C14/C18)" as
landed, but no test pinned the field-level mapping: bare deflation scalars ->
Some(...), absent plateau keys -> None. families.jsonl/runs.jsonl are
append-only, so a winner stamped pre-0077 must read back; now pinned.
- [low] Synced the ledger's inferential-validation open thread
(docs/design/INDEX.md): #145 plateau-over-peak landed (cycle 0077), selection
is now a pluggable objective (bare argmax -> trials-deflated -> plateau) on
the manifest carrier; only #146 (cross-instrument generalization) remains of
the milestone's three pieces.
- [medium-high] Removed the cycle ephemera (git rm docs/specs/0077-*,
docs/plans/0077-*) per the cycle-close convention.
Regression: full workspace suite green and clippy --all-targets -D warnings
clean (verified at feat-review time). No baseline scripts configured; the test
+ clippy gates are the regression gate. Cycle 0077 tidy (clean) — drift-clean,
not a milestone close (the milestone fieldtest is a separate deliberate gate).
Executable plan for cycle 0077 (#145), decomposed into 5 tasks with the
compile-gates sequenced:
1. Reshape FamilySelection/SelectionMode across 3 crates (mechanical,
byte-preserving): deflation fields -> Option, add PlateauMean/PlateauWorst
+ neighbourhood_score/n_neighbours; thread optimize_deflated + all tests +
the runs_family display (argmax bytes unchanged).
2. GridSpace::axis_lens() + SweepBinder::sweep_with_lattice (sweep delegates,
every existing .sweep() caller byte-unchanged).
3. optimize_plateau + PlateauMode + closed_neighbourhood (mixed-radix grid
neighbourhood, argmax of the smoothed surface) + a higher_is_better refactor
so direction lives in one place.
4. CLI --select parse + Selection threading + sweep-entry Option<lattice>
tuples + select_winner (the RandomSpace-refuse guard) + walkforward_family
dispatch; all signature-change callers threaded before the build gate.
5. runs-family plateau E2E golden.
Two plan-time forks were derived and recorded on #145 (comment 1974): the
lattice surfaces at the engine terminal (only the post-resolve_axes GridSpace
holds param_space order), and the RandomSpace-refuse is a structural guard
unit-tested at select_winner (walkforward has no --random producer to E2E).

Architect drift review (c192dfd..a295905): drift_found, medium/low only — no
ledger or hot-path contract crossed. C23-additive, C1-deterministic, C14/C18
back-compat all verified green (full workspace suite + clippy). No regression
scripts configured (test+clippy are the gate).
Resolution:
- [medium] three spec-promised optimize_deflated tests were missing (the
centring control, the all-noise high-p companion, the C2 IS-only read) — the
centring was unprotected ("removing it would pass every test"). Plus an
unguarded dispersion-floor sign assumption. FIXED in 0076.tidy (ecc9541).
- [low, RATIFY] the ledger's "Open architectural threads" inferential entry was
stale on one fact (it described optimize as having no trials penalty). Synced:
it now records that #144's trials-deflation landed this cycle (additive
optimize_deflated, winner unchanged — C23; optimize/rank_by stay bare argmax),
that #139's per-candidate OOS bootstrap landed in 0075, and that #145/#146
remain open. This ratifies the cycle-0076 intent; the gap description is
preserved for the still-open default-ranker path.
Deferred (spec 0076 Out of scope, not drift): n_eff effective-trials advisory,
reload-time recompute of the R-arm statistic, deflated-score re-ranking, CLI
flags for the resampling config.
Ephemeral spec + plan (docs/specs/0076-*, docs/plans/0076-*) removed per the
cycle-close convention. refs #144
Architect drift review (c99e7b8..2e77ab1) against the design ledger +
CLAUDE.md invariants: drift-clean, debt only — no contract or spec
violation. Verified intact: C18 wire shape (trade_rs is #[serde(skip)] +
excluded from the hand-written PartialEq; runs.jsonl/families.jsonl bytes
and digests unmoved; mc_r_bootstrap is a printed line, never a record),
C1 determinism (seeded r_bootstrap + disjoint walkforward windows, both
pinned by byte-identical-rerun e2e tests), C7 frictionless Stage-1
(round_trip_cost stays 0.0), C8/C12 streaming reduction (IS sweep folds
O(trades)/member, OOS run non-reduce). The verbatim summarize_r /
r_metrics_from_rs float duplication is guarded by the cross-reducer
equality test — sound.
Tidy applied this close:
- doc-link drift: the new E[R] notation in r_bootstrap / RBootstrap /
run_mc_r_bootstrap doc-comments was parsed by rustdoc as an intra-doc
link `[R]` (4 warnings). Wrapped in backticks; doc build now clean.
- coverage micro-gap [low, architect]: added a tripwire asserting a
populated trade_rs is absent from the serialized JSON (the serde(skip)
C18-preservation property had no direct test — only Vec::new() was
serialized before).
Carry-on (benign debt, not fixed): the mc usage literal carries a `usage:`
prefix the sibling sweep/walkforward usages omit — required because the
new `["mc", rest @ ..]` arm now handles the `--real` rejection and the
preserved golden asserts stderr.contains("usage"); churning the golden to
drop the prefix is not worth it.
Removed the cycle's ephemeral spec + plans (docs/specs/0075,
docs/plans/0075, docs/plans/0076) per the lifecycle rule.
Verified: cargo test --workspace 610 passed / 0 failed, clippy -D warnings
clean, cargo doc --no-deps clean.

Iteration 2 of cycle 0075: the engine primitive r_bootstrap (moving-block
bootstrap over a flat R series, reusing MetricStats/SplitMix64); the CLI
parse_mc_args/McArgs split (synthetic seed-resweep preserved byte-for-byte;
the --strategy stage1-r real-R path reuses iter-1's walkforward_family +
RMetrics.trade_rs); run_mc_r_bootstrap prints one mc_r_bootstrap line. The
mc real-R path accepts only --strategy stage1-r, so a bare --real stays a
usage error (mc_rejects_real_flag_with_usage_exit_2 preserved).
refs #139
Architect audit: drift-clean. The ledger and source now point at the recorded
geometry sidecar; no live reference to the removed authored floor survives in
code or any live contract. Refuse-don't-guess preserved.
Recorded debt (non-blocking, accepted):
- fieldtests/milestone-runway references the removed instrument_spec; a frozen
non-workspace snapshot, left untouched per the tracked-fieldtests convention.
- cli_run.rs test fn names retain unspecced/vetted vocabulary (plan prescribed
substring-only edits); cosmetic.
#124 stays open for the deferred override/floor tiers the Stage-2 broker needs.
Drops the ephemeral cycle spec + plan (rationale lifted to the ledger).
Cycle-close audit: drift-clean on all load-bearing invariants (C7/C8/C15 hold; geometry stays non-scalar metadata, the Source seam still carries only (Timestamp, Scalar); scope boundary held — no resolver, quote_currency still &'static str, both #124's).
Tidy: completed the VETTED_SYMBOLS consolidation the feat commit over-claimed — migrated the two remaining inline vetted-symbol arrays in the crate-internal unit tests (instrument_spec_pip_value_matches_contract_times_pip, instrument_spec_ids_are_distinct) to the const, so #140 now extends one list.
Ledger: lifted this cycle's durable rationale into the C15 realization note (docs/design/INDEX.md) — the floor now carries tick_size/digits, and the recorded-metadata tier-2 source (instrument_geometry over symbol_meta -> neutral InstrumentGeometry, cross-checked against the authored floor) now exists at the ingestion edge; the tier-composing resolver remains #124.
Drop the ephemeral cycle spec + plan (docs/specs, docs/plans) per the lifecycle convention; durable rationale now in the ledger + the #143 thread.
refs #143
Three tasks at the aura-ingest edge: (1) re-export InstrumentGeometry + a thin instrument_geometry accessor over symbol_meta; (2) two additive InstrumentSpec fields tick_size/digits (compile-gated literal update); (3) a real-data cross-check of the authored floor vs provider geometry, iterating the vetted set.

The EWMA Bollinger-band mean-reversion fade is refuted: no cross-index
generalization (FRA40 leans positive, GER40 negative — two correlated indices
disagreeing in sign), no OOS-significant cell on either index, and its lone
IS-significant cell is consistent with multiple-testing noise (full verdict on
#137). The machinery (--strategy stage1-meanrev, the composed EWMA Bollinger
band, zero new nodes) is permanent and kept; only the per-cycle spec/plan are
dropped per the ephemeral-artifact lifecycle convention.
