Four tasks: (1) engine identity projection — factor build_doc/serialize_doc
out of blueprint_to_json (byte-preserving, guarded by the canonical golden),
add blueprint_identity_json + strip_debug_symbols + 4 property tests
(renamed twins, openness, bound values, edge swap); (2) CLI --identity-id
sibling flag — composite_from_str factored out of build_from_str, the
exactly-one introspect dispatch deliberately relaxed so the two id flags
combine (one build, both ids, content id first), plus the in-crate
cross-path twin test (Rust sma_signal vs op-script twin: distinct content
ids, one identity id — placed beside the existing cross-surface pins since
sma_signal is private to the bin); (3) four e2e tests incl. the previously
uncovered count!=1 usage path; (4) full regression (873 -> 882 expected).
Plan-recon corrections folded in: the spec sketch's BlueprintData does not
exist — the real DTO is CompositeData; engine re-export + CLI import are a
lockstep pair.

Architect review of b672a37..HEAD. What holds: emitted templates match
the settled contracts (Aura.toml paths-only per C17, cdylib + empty
[workspace] per C16, ::-namespaced ids per the charter, the C14 exit
partition in dispatch_new); the load-bypass guard is narrow and sound
(only the new-project verb exempted, the load arm byte-unchanged for
every other verb); e2e coverage is real (scaffold -> build -> run twice
byte-identical, namespace stamped, introspection, four refusals, the
unbuilt-tree bypass, plus the additive namespace-override test).
Regression: cargo build --workspace rc=0; cargo test --workspace 873
passed / 0 failed (project_new 6/6); clippy --workspace --all-targets
-D warnings rc=0; cargo doc --workspace --no-deps 0 warnings. No
baselines exist to move, so nothing to ratify.
Drift resolved in this commit: three doc mirrors still framing the
scaffolder as future — project-layout.md's 'the future aura new
scaffolder will emit this line; until then, add it by hand', the C24
status paragraph's 'what remains open is the aura new scaffolder (the
milestone's next cycle)', and the #109 open-thread bullet's 'the aura
new scaffolder and the experiment-builder API remain open' — all
rewritten to the landed reading (only the experiment-builder API stays
open in that layer).
Carried debt, filed forward: the scaffold templates and the
demo-project fixture encode one project shape twice with no lockstep
guard and deliberate cosmetic divergences (#181, idea — needs a design
pass, not a mechanical edit).
Process note: one mid-cycle plan-fix commit (derive(Debug) on a
plan-prescribed struct whose own test code required it) — the
implement loop's spec gate correctly blocked the necessary deviation;
resolution followed the fix-plan/commit-subset/re-run path.
Ephemeral cycle artifacts removed per convention: spec 0103, plan 0103.
refs #180
The Task-1 unit tests call unwrap_err() on Result<ScaffoldSpec, String>,
which requires ScaffoldSpec: Debug; the prescribed struct lacked the
derive, so the plan's own bytes could not compile. The implement loop
correctly blocked on the necessary deviation (spec-compliance holds
verbatim plan code); this aligns the plan with the only compiling form.
refs #180
Architect review of d7c935d..HEAD. What holds: C13/C16 separation
verified by diff (descriptor in aura-core::project, loader entirely in
aura-cli::project, aura-engine gains only the additive provenance
field); the C-tier-before-Rust-tier discipline is enforced in load()
(magic -> version -> stamps, fn pointers touched only after Ok);
C17/C24/invariant-9 hold (paths-only Aura.toml, injected merged
resolver, charter at the one seam); outside-a-project byte-identity
confirmed by the full green suite incl. every golden-bearing test.
Regression: cargo build --workspace rc=0; cargo test --workspace 862
passed / 0 failed (cli_run 133, project_load 7 e2e); clippy
--workspace --all-targets -D warnings rc=0; cargo doc --workspace
--no-deps 0 warnings. No baselines exist to move, so nothing to
ratify.
Drift resolved in this commit: two stale project-as-crate ledger
mirrors — the C24 status paragraph still calling the layer
sequencing-coupled/unbuilt, and the #109 open-thread bullet naming it
an unbuilt half — rewritten to record the landed load boundary (the
aura new scaffolder and the experiment-builder API stay open).
Carried holds (plan-prescribed bytes, cosmetic): the unreachable
rsplit fallback in node_name, the unreachable! build closure in one
aura-core test.
Ephemeral cycle artifacts removed per convention: spec 0102, plan 0102.
refs #180
Architect review of 8814e295..HEAD. What holds: the cosmetic-only claim is
verified (every -/+ pair in the code diff is a string literal; no exit(),
channel, or control-flow byte moved; the C14 usage=2/runtime=1 partition
preserved at every touched site); grep gates exact (zero lowercase usage:
literals, 11 'Usage: aura' source lines = 10 edited + the pre-conforming
run_args_from); fieldtests corpus and refusal diagnostics byte-identical.
The recorded spec deviation (3 additive house-style pins) strengthens
coverage over a real pin gap and is decision-logged on the issue.
Regression: cargo build rc=0, cargo test --workspace rc=0 (cli_run 133
passed / 0 failed), clippy -D warnings rc=0, doc build rc=0. No baselines
exist to move, so nothing to ratify.
Drift resolved in this commit: the C14 ledger note still described the
casing normalization as deferred after #179 landed - rewritten to record
the landed house style (usage lines 'Usage: aura <verb> ...', refusal
diagnostics deliberately unprefixed).
Ephemeral cycle artifacts removed per convention: spec 0101, plan 0101.
refs #179
One lockstep task: 10 byte-exact literal edits (6 lowercase usage: flips,
4 bare closures gain the 'Usage: aura ' prefix, mc built-in gets the program
name in both alternatives) + the single casing-sensitive pin flip in
cli_run.rs, then build / targeted test / full suite / clippy / grep gates /
diff-shape gate / sweep smoke.
refs #179
Architect review of 88e9c9a..HEAD. What holds: token purity of the rename
(removed + mapping == added, 33 sanctioned prose rewordings, numeric golden
bytes untouched); CLAUDE.md invariant 7 now matches the ledger C10 section
clause-by-clause; no silent alias for the old selectors (unknown-selector
exit-2 path is tested).
Regression: cargo build / clippy -D warnings / doc build clean; cargo test
--workspace rc=0, 51 targets, 0 failures. No baselines exist to move, so
nothing to ratify.
Drift resolved in this commit: the C10 terminology note (INDEX.md) still
called Stage-1 a surviving identifier name after the glossary recorded the
rename - aligned to name the r-family rename (#174). Remaining low items:
the spec's own survivor-list contradiction was ratified and recorded on the
issue; the RGrid const-seeding debt is recorded on the harness-retirement
issue (refs #159).
Ephemeral cycle artifacts removed per convention: spec 0100, plan 0100, and
the spent prior-milestone fieldtest spec.
refs #174
Five ordered tasks: aura-cli source + include_str-coupled fixtures, the
cli_run suite, engine e2e git-mvs + doc-refs, dead-ordinal prose across
rustdoc/CLAUDE.md/glossary/ledger live lines, and a workspace grep gate.
Substitutions are ordered longest-token-first; every task carries its own
verification gate.
refs #174
Architect drift review (scope 780d823..HEAD, the sole gate — no regression
script) returned one medium ledger-gap, now resolved; otherwise drift-clean with
a positive What-holds:
- invariant 8 / C16 engine-domain separation preserved: clap is confined to
crates/aura-cli/Cargo.toml; the whole diff touches only aura-cli/ + Cargo.lock
+ ephemeral docs; no engine/std/composites/analysis/registry/core/ingest crate
mentions clap, so the frozen deploy artifact structurally cannot pick it up
(aura-cli is a leaf binary). The 16 new lock entries are exactly clap's tree.
- C16 per-case admission honest: clap admitted with a documented rationale at the
Cargo.toml site (replaces the hand-rolled parser + ten help surfaces; dev-loop
tax, not frozen-artifact tax), the same admission form as sha2/libc.
- C14 automation-face served, execution layer intact: the usage=2/runtime=1
partition, scoped --help, --version, and GNU flags match the spec; the domain
fns keep their signatures (arg-plumbing via thin *_from adapters); new
behaviour is pinned (partition property test, version, scoped-help, dual-grammar
stray-positional guard).
Ledger refreshed: the C14 realization block now records the clap adoption + the
exit-code partition (usage=2/runtime=1) as a durable automation contract, before
the ephemeral spec that first stated it is removed (the drift item the architect
raised).
Deferred/forward: error-message casing normalization (#179, idea); the
machine-first help surface stays on the #157/C21 track (Fork B settled this cycle
as human/GNU convention compliance).
Verified green (orchestrator, this session): cargo build --workspace clean; cargo
clippy --workspace --all-targets -- -D warnings clean; cargo test --workspace
green. Cycle drift-clean.
closes#175
Iteration-2 plan for #175: apply the clean exit-code partition (deviation #8) on top of the clap migration — runtime failures exit 1, usage errors exit 2, no same-class inconsistency. Uses the attribution principle (command-line fault = 2, missing-environment/bad-stdin = 1) to resolve the 6 boundary cases the spec under-specified. refs #175
Iteration-1 plan for #175: replace the hand-rolled aura-cli argv parser with a
clap derive parser (scoped `aura <sub> --help`, `--version`/`-V`, per-flag
Options section, `--flag=value`/`--`/long-opt abbreviation), behaviour-preserving
on exit codes. Task 1 adds clap + RED tests for the new behaviour; Task 2 is the
atomic migration + renegotiation of the help/usage pins the migration inverts
(the four dual-grammar subcommands mapped as optional [blueprint] positional +
post-parse is_file() dispatch; execution layer untouched). The exit-code split
is iteration 2.

cycle 0097 tidy (clean). Architect drift review over 485f3c8..HEAD: no code
drift, no debt. Regression: no dedicated script (architect is the sole gate);
its "What holds" is non-empty (design commitments confirmed against the diff):
- Inv. 8 / 9: the cycle touches only crates/aura-cli (main.rs + cli_run.rs +
the ephemeral spec/plan); walk_forward/WindowRoller/FamilyKind::WalkForward/
append_family/put_blueprint are read-only reuse, no engine/registry change.
- Inv. 1 / 2: blueprint_walkforward_family reuses the generic walk_forward roller
(windows disjoint-parallel, across-sim); each IS-sweep/OOS-run sees only its
window's windowed_sources; IS precedes OOS per window — no look-ahead.
- Reproduce lockstep: the reproduce_family_in WalkForward arm rebuilds each OOS
slice from stored.manifest.window (before the _ => run_sources fallthrough that
would rebuild the wrong full-window source); winner params via the shared
manifest->cells recovery; pinned by the reproduces_bit_identically E2E.
- Structural mirror + panic-safety: one-substitution-deep twin of the hard-wired
Stage1R arm (select_winner + walk_forward reused, metric sqn_normalized);
run_blueprint_walkforward follows the content-addressed sibling pattern (no
ensure_name_free); blueprint_sweep_over returns Result<_,BindError>, a bad axis
is in-closure exit 2 (never a panic); run_oos_blueprint derives pip internally
(7 args, no #[allow]).
Ledger: refreshed the C24 realization block (docs/design/INDEX.md) — replaced the
now-false "Walk-forward is deferred (#173, dep #169)" sentence with the "IS-refit
walk-forward shipped (cycle 0097)" note; and extended the C18 reproduction note —
reproduce now spans the third family kind (WalkForward), so all three FamilyKind
variants persist AND reproduce through the one shared topology_hash+put_blueprint
hook.
Milestone: the World/C21 blueprint-data family surface (run/sweep/mc/walkforward/
list-axes/reproduce) is coherent and complete per the architect review — no
structural gap. This audit proves drift-clean; a green end-to-end MILESTONE
FIELDTEST remains the deliberate gate to formally close the World/C21 milestone.
Ephemeral spec/plan git-rm'd per the lifecycle convention.
refs #173
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.
refs #173
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

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

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.

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.

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).

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.

Remaining). No struct/signature/runtime change. refs #156

fieldtest (#161 cycle-reject + #162 diagnostics-by-identifier). Regression gate:

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.
refs #153
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.
refs #148
Parent spec docs/specs/0085 (19ba1ec). 4 tasks: (1) ChargeMode + the PerHeldCycle
accrual branch on the shared CostRunner (AtClose arm kept verbatim for byte-identity)
+ 2 RED B-proof unit tests; (2) the CarryCost node (ConstantCost twin, PerHeldCycle)
+ lib.rs registration; (3) the --carry-per-cycle CLI flag threaded through every site
(incl. the easy-to-miss main.rs:4446 bin unit-test call site); (4) two capture-then-pin
net_expectancy_r goldens + the net_r_equity-bleeds-over-the-hold integration B-proof.
summarize_r and the CLI net_eq wiring are UNCHANGED; the cycle-0083/0084 goldens are
the byte-identity regression net.
refs #148
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.

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.
