Brummel c787488e64 plan: 0083 cost-node trait + shared cost-record contract
6 tasks: (1) new cost.rs — CostNode trait + CostRunner<F> + cost_node_builder +
shared COST_FIELD_NAMES/COST_WIDTH/GEOMETRY_WIDTH + runner tests + author doctest;
(2-3) migrate ConstantCost/VolSlippageCost to thin factors; (4) CostSum reads the
shared contract; (5) main.rs reads aura_std::COST_FIELD_NAMES; (6) workspace gate.
Behaviour-preserving — the existing suite is the regression net.

Brummel 6c7f5dd147 audit(0082): cycle close — drift-clean; C10 cycle-0082 note + cost-flag validation symmetry
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).

Brummel 7f3756a395 feat(0082): cost-graph composition — VolSlippageCost + CostSum net-R aggregate
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).

Brummel 31ef46314a plan: 0082 vol-slippage cost + cost-graph composition
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).

Brummel e82725f2d7 audit(0081): cycle close — drift-clean (code); ledger C10 realization note + stale-broker doc sync (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).

Brummel 15f5c0bc99 audit(0078): cycle close — drift addressed; ledger inferential-thread synced (milestone complete) + C12/C18 realization; drop ephemera
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.

Brummel cffc297e9a plan: 0078 cross-instrument generalization
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

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.

Brummel d50a4828ad audit(0077): cycle close — drift addressed; legacy-load fixture + ledger sync; drop ephemera
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).

Brummel fd221c81ec plan: 0077 plateau over peak selection
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).

Brummel 9c6b9c7ea9 audit(0076): cycle close — drift addressed; ledger inferential-thread synced; drop ephemera
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.

Brummel c192dfd344 audit(0075): cycle close — drift-clean; doc-link + trade_rs tripwire tidy; drop ephemera
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.

Brummel ffd18b98ea audit(0070): cycle close — lift finalize lifecycle to ledger C8, drop ephemera
Cycle 0070 (streaming sink reductions, #138) close. Durable rationale lifted to
the ledger: C8 now records the end-of-stream `finalize` lifecycle (the second node
phase beside `eval`), its `Harness::run` topo-order epilogue, and its C1/C7/C8
reconciliation — with the open `Recorder`->`Probe` / per-cycle-allocation question
(#77) cross-referenced, since `finalize` is the "non-channel exit" that issue's
accumulate-then-read option named as missing. The per-cycle spec and plan are
git-rm'd (ephemeral, valid only for their cycle).

Audit (architect) found no invariant breakage; noted debt, left as-is: the
two-mode `stage1_r_graph` (reduce vs raw sink wiring) rests on the CLI-seam
equivalence test rather than structural unification, and `SeriesReducer.last_ts`
carries the last *warm* cycle's ts (latent only if `--trace` ever folds).

(C7), each event's event_ts is its own cycle (C2), the >1-event-per-instant
reversal case is why it is derived not per-eval (C8/C10); aura-engine -> aura-core
only (instrument_id a caller scalar, no InstrumentSpec import).

- Ledger C10: add a "Realization (cycle 0068, #115)" note — derive_position_events
  as the first difference of the executed book, the post-reframe replacement for
  the rolled-back 0064 derive; fixed-fractional / currency / equity-feedback
  sizing and the realistic brokers stay #116.
- Remove the ephemeral spec + plan (cycle closed; rationale in the ledger + git
  history).

Accepted low debt (architect [low]): the stop-then-same-cycle-reopen producer path
emits the same closed&&open shape as a bias-flip reversal and the derive handles it
correctly (it keys on closed/open/direction/size, not exit_reason; unit-covered via
the reversal test), but is not separately asserted end-to-end. Cosmetic; the derive
is producer-agnostic.

Architect audit clean (no drift, no debt): raw sqn verified bit-identical,
C18 serde back-compat + C4 SoA seam + C1 determinism + Part-B symmetry all hold.

  the turnover-robust opt-in rank key (raw sqn / default ranker byte-unchanged,
  serde(default) for back-compat), and per-member --trace now symmetric across
  all three sweep strategies via the shared persist_traces_r.

5-task plan for the boss-signed spec docs/specs/0067-r-sweep-followups.md.
Task 1 adds RMetrics.sqn_normalized (+ SQN_CAP + summarize_r compute) and
threads all four RMetrics struct literals (compile-gate). Task 2 adds the
Metric::SqnNormalized rank key. Task 3 re-baselines the 0066 single-run
golden (the r: block gains the field). Task 4 wires --trace for the stage1-r
sweep (invert the refusal test → persist member dirs via persist_traces_r,
drop the run_sweep guard). Task 5 is the full-workspace gate.

Brummel 986a9fd5c7 audit(0066): cycle close — lift R-sweep/SQN rationale to ledger, drop ephemera
Cycle 0066 (#133) closed. The close audit (architect) found the family ratified against C12 axis-2 (rank-by-metric over the C18 family store) and the C10 R framing, with one [high] gap (swept-member manifest omitted the fixed R-defining params) fixed forward in 499121e.

- Ledger: a C10 realization note records the durable rationale -- SQN as the single-number sweep objective, the signal-only grid (the stop defines R, so varying it breaks cross-member SQN comparability -- the SQN100 #130 motivation), the R-metric rank vocabulary, and the manifest-completeness fix.
- Glossary: new 'R metrics' and 'SQN' entries.

Brummel 13086b8590 plan: 0068 stage1-r CLI surface (iter-3)
Executable plan for iteration 3 of cycle 0065 - make the Stage-1 R layer
operable from the command line. Three tasks:
- Task 1: promote vol_stop + risk_executor + a StopRule axis from test
  fixtures to public aura-engine composite-builders (aura-std moves to a
  normal dep; the two fixtures rewired to call them; a Vol-backed RED test
  added).
- Task 2: the stage1_r_blueprint dual-tap harness (one bias fanned into both
  SimBroker and the RiskExecutor) + run_stage1_r folding summarize_r into
  RunMetrics.r + persist_traces_r (a separate 3-tap helper that leaves the
  seven pip callers byte-unchanged).
- Task 3: a parse_run_args tokenizer + --harness selector + run_dispatch,
  replacing the run literal-slice arms; binary-driven selector / flag-
  composition / r_equity-round-trip tests.

Recon: two plan-recon agents (aura-cli surface, aura-engine promotion).
Verified before handoff by a 3-critic adversarial pass (API-fidelity,
plan-discipline, behavioral-correctness): discipline and behavior SOUND, one
API fix applied (tempdir -> the existing temp_cwd helper, no tempfile dep).

Brummel 6e214957d1 plan: 0067 stage1-r iter-2 — Sizer + RiskExecutor + metric enrichment
Iteration-2 plan for cycle 0065 (Stage-1 R signal quality). Sub-splits the
spec's iteration 2: this plan is the node + metric layer; the CLI/recording
surface (#129) becomes a separate iteration 3.

Five tasks, sequenced so each signature change threads all its callers before
its build gate, and the two signature changes land before the composite that
consumes both:

1. PositionManagement gains a 4th `size` input (col 10, from the Sizer); R
   stays size-INVARIANT (RED test pins it). Threads the PM unit tests + the
   stage1_r_e2e direct-eval column setups.
2. Sizer node (aura-std): `size = risk_budget / stop_distance`, flat-1R; the
   Stage-2 fixed-fractional seam slots in unchanged.
3. summarize_r enrichment: SQN, conviction terciles, net-of-cost; gains a
   `round_trip_cost` param (reads dense cols 6/7/9). Threads report.rs + the
   E2E callers and extends the cross-crate layout guard.
4. RunMetrics.r: Option<RMetrics> with serde(default, skip_serializing_if) for
   legacy runs.jsonl back-compat. Threads every RunMetrics literal (report.rs,
   aura-registry, aura-engine/mc).
5. RiskExecutor composite (aura-engine integration-test fixture, sibling of
   vol_stop_composite): FixedStop -> Sizer -> PositionManagement behind open
   bias+price roles, price fanned to both; bias produced in-graph (single
   source, no stale-price two-cycle merge). Veto is a documented seam, not a
   node. E2E equivalence + R-invariance under risk_budget.

The two genuinely-missing arithmetic primitives (Mul = two-stream f64 product,
Sqrt = one-input f64 root, negatives clamped to 0). They are the building blocks
for the volatility stop as a composition (rolling EWMA stddev), replacing the

primitive is added, not fused away. Adds Mul + Sqrt primitives, removes the fused

Brummel 7d7d1f72d9 audit(broker-foundation): cycle close 0063 — ledger records the C10 A-side foundation (#113 + #114)
Cycle-close tidy for broker-foundation (InstrumentSpec deploy metadata #113 +
PositionEvent schema #114).

Architect drift review (3638d48..HEAD): code is drift-clean. PositionEvent matches
the C10 column spec field-for-field (no open_ts, unsigned volume, direction-is-action,
bare-i64 action); the engine run-loop is untouched (C14); InstrumentSpec stays Copy
metadata at the ingestion edge (C7/C15); no instrument identity reaches the hot path.
The only drift was stale ledger prose, fixed here:
- C10 realization note: added a cycle-0063 entry recording that the position-event
  *schema* landed (PositionAction/PositionEvent), while derivation (#115) and the
  realistic broker nodes (#116) remain the deferred decoupled layer.
- C15 realization note: replaced "minimal today (pip only)" with the six-field
  deploy-grade floor and the #124 currency-type forward note (quote_currency is
  &'static str; the #124 resolver chooses how its runtime tier carries currency).

Regression (verbatim): cargo test --workspace = 458 passed / 0 failed (exit 0);
cargo clippy --workspace --all-targets -- -D warnings = clean (exit 0).

Carry-on (not actioned, justified): the inline reversal test is a shape-pin only —
the behaviour test arrives with #115's derive, and the E2E twin already exercises the
reversal wire shape. The quote_currency &'static str / #124 resolver concern is logged
on #124 as a deliberate deferred design choice.

This is drift-clean, NOT a milestone close — the realistic-broker milestone needs its
end-to-end fieldtest green, which depends on #115/#116/#120-123 still to land.

Removed the ephemeral cycle artifacts (spec + plan) per the lifecycle convention.

Brummel e01bdc3d5e audit(visual-world-cut-2): cycle close 0062 — ledger records cut 2 (#102 + #108)
Cycle-close tidy for visual-world-cut-2 (decimation #108 + run-context header #102).

Architect drift review (53eeba5..HEAD): the only drift was a STALE LEDGER — the C22
section still listed #102 (run-context header) and #108 (decimation) as deferred/open
after they shipped in 476342d. Resolved in this commit:
- the #101 first-cut note no longer claims "not yet a run-context header";
- a new "served-page hardening — cut 2" amendment records #102 (ChartMeta +
  buildHeader, family window = span across members) and #108 (the pure decimate
  min-max transform) as landed, both CLI-side (C14);
- the "Open architectural threads" list drops the now-landed run-context header.

Substantive gates (self-verified): C14 honoured — all decimation/header/pixel logic
is in aura-cli (render.rs/main.rs/chart-viewer.js); the only engine touch in range is
the one-line #100 cell.rs doc. C1 preserved — decimate is pure, deterministic
bucketing over the sorted-deduped spine, no-op under budget, monotonic spine (pinned
by a unit test). Regression: cargo test --workspace = 446 passed / 0 failed; cargo
clippy --workspace --all-targets -D warnings clean. No separate baseline script.

Residual debt filed as #110 (idea): the decimation budget is a fixed const (no
--width flag), and the min-then-max sub-pixel ordering is a real ts-displacement in
the non-default continuous x-mode. Both are local aura-cli refinements, neither a bug.

Ephemeral spec/plan removed at cycle close (docs/specs/0062, docs/plans/0062).

Brummel 53eeba5e16 audit(families-view): cycle close 0061 — drift-clean, ledger records the comparison view
Architect drift review over 99fd32b..HEAD (the housekeeping commits #99/#98 plus
the 0061 cycle): code drift-clean. Engine untouched (aura-engine + aura-core diff
empty — C9/C14); C21 realized faithfully (the comparison view consumes a set of
runs, a family is the first producer, no orchestration-axis rebuild); C18/C10
refuse-don't-guess honoured (every new error path exits 2, never panics; all six
tracing entry points guarded before persist, so name resolution is total). The only
finding was a ledger-realization gap, lifted in this commit.

Ledger (docs/design/INDEX.md): added a C22 amendment recording the
families-comparison view as realized (#107) — aura chart <family> overlays one tap
across a family's members on a shared y-scale, union-ts spine giving one mechanism /
three correct readings, the write-guard totalising name resolution; reconciled the
two stale "families-comparison ... remain open" lines (the #104 note and the
open-threads list) and named the deferred follow-ons (#102 run-context header, #47
multi-column tap selection, the orchestration-composability rebuild).

Regression: cargo test --workspace green (no failures), clippy --workspace
--all-targets -D warnings exit 0, cargo build --workspace clean — verified by the
orchestrator before close. No baseline to update (aura's regression gate is the
gated determinism suite, which is part of the workspace tests).

Brummel 607e5487e9 audit(real-family): cycle close 0060 — ledger records the real-data family axis
Architect drift review (b92aab7..HEAD): the cycle is contract-clean — C9 (engine
untouched, whole change CLI-side), C6/C1 (real bars streamed from the pre-recorded
archive, real sweep byte-deterministic), C10 (refuse-don't-guess shared by run
--real and the family path), C12 (MC-exclusion fenced: mc --real exits 2). One
medium ledger-gap, now closed; one low item ratified as carry-on.

- Ledger: docs/design/INDEX.md C22 gains a "real-data family source" amendment
  (#106) recording the opt-in real-data axis on sweep/walkforward families, the
  DataSource provider, the MC exclusion (Fork A), and the oos{ns} key widening.
  This was the only drift — a documentation gap, not code drift.
- Ratified carry-on [low]: the real walk-forward member key oos{from.0} is now an
  epoch-ns integer; portable and collision-free, covered in practice by the
  walkforward_real test (>=2 distinct oos<ns> dirs) and the 9-window E2E probe.
  No explicit ns-uniqueness assertion beyond starts_with("oos") — acceptable; a
  dedicated pin is not worth an iteration.
- Retire ephemeral spec/plan 0060 (git rm) per the cycle-artifact lifecycle; the
  durable record is this ledger amendment + the git history.

No regression scripts configured (architect is the gate). Full workspace test +
clippy -D warnings green at close.

Brummel b92aab713c audit(sweep-key): cycle close 0059 — drift-clean, retire spec/plan
Cycle-close tidy for the generic portable sweep member-key + bool-param demo
strategy (spec/plan 0059, reference issue #105, implementations 27f850d + 0b73a75).

Architect drift review (range 1d6fafb..HEAD): clean — no drift, no debt.
- C1 (determinism): varying_axes + member_key are pure functions of the grid
  point, no schedule state; the engine carries no trace state (consistent with
  the #104 design + the C22/#101 ledger note).
- C7/C8/C9: LongOnly is a clean one-in/one-out f64 node, None until warmed (C8
  filter), the first bool *param* through the already-ratified Cell::bool()
  path; momentum is an ordinary composite of existing nodes; brokers stay
  downstream (C10). C18/C21/C22 upheld.
- The engine accessor exposes the binder's OWN axis-cardinality knowledge (it
  holds the value-lists), not a presentation concern — formatting stays in the
  CLI. The hand-rolled fnv1a64 mirrors the ledger-blessed SplitMix64 precedent
  (harness.rs): tiny, dependency-free, bit-stable-on-purpose (std DefaultHasher
  is unstable across releases; on-disk-name stability is the per-case C16
  reason). LongOnly is a genuine universal aura-std block (long-only is
  asset-agnostic). The ledger amendment matches the code.

Regression: the project declares no dedicated regression command; the gate is
the architect review plus the full suite, verified green at 0b73a75 (cargo test
--workspace, clippy --all-targets -D warnings).

Spec docs/specs/0059 and plan docs/plans/0059 retired (git rm) per the ephemeral

Brummel 1d6fafbc39 audit(family-traces): cycle close 0058 — drift-clean, retire spec/plan
Cycle-close tidy for family-member trace persistence (spec/plan 0058,
reference issue #104, implementation d3cb5f8).

Architect drift review (range 06fdafa..d3cb5f8): drift_found, low-grade
only — no contract violated. C1 (determinism), C7 (SoA), C8 (sinks),
C18/C21 (registry/families) all upheld; the opt-in --trace path is
genuinely byte-neutral. Two items, both resolved here:

- [high] Ledger gap: the C22/#101 disk-trace note recorded only the
  single-run runs/traces/<name>/ layout. This cycle establishes a new,
  load-bearing on-disk convention (per-member nested standalone run-dirs
  runs/traces/<name>/<member_key>/) that the deferred family-comparison
  view will build on. FIXED: amended the C22/#101 realization note in
  docs/design/INDEX.md to record the layout, the content-derived
  deterministic member keys, and the parallel-safe lock-free write.

- [medium] sweep_member_key hard-codes two grid axes; collision-free only
  over today's built-in grid, a latent foot-gun if the grid varies an
  unlisted axis. Not a current defect (one grid, covered, fail-loud on a
  missing listed axis). CARRY-ON: filed #105 (idea) for generalised key
  derivation when the grid generalises.

Regression: the project declares no dedicated regression command; the
gate is the architect review plus the full suite, verified green at
d3cb5f8 (cargo test --workspace, clippy --all-targets -D warnings).
