Slice 5 of the #319 retirement. The scaffolder's project CLAUDE.md and the
CLI concepts help now teach only the surviving surface (exec over both
document classes, --override, graph introspect --params for discovery;
traces via exec --tap / presentation.persist_taps). Sweep vehicles moved
onto campaign documents driven by exec (project_new's starter quickstarts,
cli_broken_pipe — whose bare-sweep EPIPE probe was latently vacuous and now
streams a real 4-member campaign, project_sweep_campaign's real-data leg,
graph_construct's gang-axis parity pair as paired one-cell campaigns);
pure discovery sites became graph introspect --params, and the line-identity
test kept its literal --params expectations minus the sweep half. Help pins
rewritten; the scaffold template's in-src pin follows the new bytes.
refs #319
Reconciles the sweep-axis namespace (closes#328): the raw form
<node>.<param> (splice paths keep their interior path) is now the only
user-facing axis name — printed by --list-axes, accepted by --axis on
BOTH sweep routes, recorded in the synthetic run manifest, discovered
by graph introspect --params (bound params included, default= lexicon),
and validated by campaign documents. The wrapped <blueprint>.<...> form
is retired with translation refusals on both seams.
Mechanics:
- classify_axis_intake (aura-runner axes.rs): explicit raw-first
acceptance predicate shared by both --axis intake routes. Deliberately
not built on raw_matches_wrapped, whose equality branch would have
accepted the retired form silently (skeptic finding, minuted on #328).
Wrapped hit -> translation refusal naming the raw candidate (shared
prose builder wrapped_axis_refusal, one literal for both routes).
- The synthetic route resolution moves to the raw frame the real route
(bind_axes) already uses: override_paths/wrapped_bound_overrides_of
match via raw_matches_wrapped (also removing a latent slicing panic),
blueprint_sweep_family translates raw names onto wrapped SweepBinder
slots, manifest.params records raw keys (name-only reshaping, zip is
positional). The two sweep routes now share one convention.
- reproduce translates recorded manifest names raw-or-wrapped onto the
wrapped space: old registered artifacts stay replayable (C29), new
raw manifests round-trip.
- introspect --params gains the bound default= lines via the same
render_value the --list-axes bound pass uses - the two discovery
surfaces are byte-identical by construction.
- AxisNotInParamSpace carries raw_candidate; ref_fault_prose renders
the did-you-mean iff present. Sweep-terminal bind errors
(MissingKnob/KindMismatch) render the raw knob name (render seam
only; acceptance criterion: no user-facing surface prints a wrapped
axis name).
- Downstream consequence fixes: scaffold quickstart example spoke
wrapped; ~90 wrapped test literals converted to raw across six test
files (deliberately-bogus refusal names and the untouched internal
walkforward wrapped route kept, with comments).
Fork decisions and the skeptic correction are minuted on #328
(comments 2026-07-24/25). Grounding-check PASS first attempt (12
assumptions ratified). Review (opus): translation ambiguity cleared
(uniform single prefix per blueprint), reproduce both-shapes traced;
repair pass added the synthetic-route refusal e2e + the shared prose
builder. Verified: cargo test --workspace green (99 targets, 0
failures), clippy -D warnings clean.

The binary is the only always-present teacher (C29); the 2026-07-22 external
field test showed the help teaching nothing but the verb inventory. This
cycle makes every closed vocabulary the binary ships listable with a one-line
meaning, and opens the help with the concepts the field agent had to discover
forensically.
#315 — help + introspection:
- `aura --help` opens with the two-layer concepts paragraph (research verbs
as sugar over registered process/campaign documents; the directly
authorable data plane; bias-as-target-position + protective-stop execution
model in R; how traces come to exist).
- Each document-bridged sugar verb's long help names the process shape it
desugars to (sweep -> std::sweep; walkforward -> [std::grid,
std::walk_forward]; mc -> + std::monte_carlo; generalize -> [std::sweep
(selection), std::generalize]). `run` is not verb_sugar-bridged, so its
help points at the canonical document-first form instead of claiming a
desugaring it does not perform.
- `graph introspect --vocabulary` lists each node type with its schema doc
(bare names taught nothing); `--node <T>`'s head line carries the meaning.
- `graph introspect --folds` (new): the tap-fold vocabulary with bind rule,
output kind, and meaning — it existed only as source comments. The rows
live in aura-std (`fold_vocabulary`), unit-pinned against
`fold_binds_at`/`fold_output_kind` so the prose cannot drift from the
executable rules, and doc_gate-checked (C29 entry seam). The discovery
surface is graph introspect because folds bind at graph-declared taps
(C27); the document layer still refuses a folds slot pending #310.
- `process introspect --metrics` lines carry each metric's meaning (the doc
column existed since #316 but was never printed).
- `campaign introspect --block std::presentation` lists the four persisted
taps' meanings under the persist_taps slot.
- The scaffolded project CLAUDE.md teaches the execution semantics (bias as
held target, protective stop, R) and the document data plane.
#323 — C29 authoring surfaces:
- `introspect --unwired` enumerates the optional `description` envelope slot
for both document kinds (absent-only, like risk/cost); the campaign lib
fixture gains a description, and the risk/cost-bound e2e binds description
too so "no open slots" keeps meaning complete.
- `graph build --help` carries the op-list reference: all nine op kinds with
fields and a worked element each (OP_REFERENCE lives beside OpDoc so a new
variant is one screen from its help line).
- The authoring guide's S0 worked literal is byte-pinned to the scaffold's
LIB_RS template (rendered with the guide's my_lab namespace); the scaffold
e2es compile that template for real, so the pin is a transitive compile
guard. The template gains the guide's C29 comment, the guide gains the
template's rename note — one worked example, two surfaces, zero drift.
Deliberately out of scope (ratified #319, 2026-07-24): no doc-strings for
the quintet's 48 flag fields — the sugar surface retires; only the pointer
lines above bridge toward the document layer.
Verification: full workspace suite green, clippy -D warnings clean,
aura-bench exit 0 with all fingerprints OK (help_ms +1.6% — the longer help
text, in tolerance), cargo doc warning count unchanged (7 pre-existing).
9 new e2e pins in tests/help_self_description.rs; guide + CLAUDE.md pins in
scaffold unit tests; fold-vocabulary rules + doc_gate unit-pinned in
aura-std.

Iteration stderr-markers-1, tasks 1-2 of the stderr-class-markers plan
(spec signed via grounding-check PASS, decisions logged on #278).
The two stderr diagnostic classes become machine-separable (refs #278):
a new crate-internal diag module owns the grammar as note!/warning!
macros (`aura: note: <text>` benign continuing-run diagnostic,
`aura: warning: <text>` recorded fault the run survives); the four
undifferentiated sites are retagged — gate-emptied cell -> note,
failed cell / walkforward cell / mc cell -> warning — and the four
scaffold literals migrate onto the shared macro (output bytes
unchanged). The always-on record summary line gains the bare `aura: `
namespace it was missing; bare-prefix stays the vocabulary for error
lines accompanying a non-zero exit (C14 partition) and plain info
lines. Exit codes unchanged throughout.
Verification: RED->GREEN warning pin on the per-cell-fault e2e; new
gate-emptied e2e (impossible n_trades threshold) pins the note marker,
exit 0, and the summary-line prefix; scaffold e2es and the full
workspace suite green; clippy -D warnings clean on aura-cli. The C28
shell-module roster test gained the diag.rs entry.
Known residue for the next slices: aura-runner literals (stale-dylib
warning, three tap/no-nominee notes) and the #313 zero-trade notice
follow in tasks 3-5. The verb_sugar warning call sites remain e2e-
uncovered (a hostless walkforward fault fixture is structurally
unreachable — single-instrument validation refuses before the cell
loop); their grammar is pinned via the shared macro and the campaign
warning e2e.
refs #278
Iteration 3 of the self-description plan, tasks 1-3 (checkpoint commit
mid-iteration; the register e2e, the op-script doc slot, and the full
gates follow):
- aura-research: DocFault::BadDescription { subject, fault }; a present
document description passes doc_gate in validate_process /
validate_campaign (absent is never a fault and stays byte-identical);
prose arm in doc_fault_prose; tests incl. content-id participation.
- aura-registry: the store boundary gates admission -- the public
put_blueprint parses the canonical bytes and walks root + named
nested composite docs (None refuses like ""), refusing via
UndescribedComposite { name, fault } / MalformedBlueprint; the raw
write survives as private put_blueprint_unchecked (store-mechanics
tests + the never-retroactive witness: doc-less pre-C29 entries stay
readable). Registry-internal seeders triaged junk-vs-real.
- authored root docs: the 4 example blueprints + their 4 open-fixture
twins, the scaffold starter template, the scaled_signal and hl_signal
inline fixtures, and the three programmatic member.rs builders
(breakout, meanrev, hl_channel) via GraphBuilder::doc -- mechanical
propagation of the authored lines.
Recovery note: the implement run's task 3 discarded tasks 1+2's edits
in three files via a file-level checkout (the issue-#23 guard shape);
the loop's boundary snapshot caught it and the content was restored
from recovery snapshot 11a6ae2, then re-verified (research 81 green,
registry 51 green, cli 58/59).
Known-open at this checkpoint: the op-script register test is red --
op-built composites have no doc surface (#125 scope cut); the op
vocabulary grows the anticipated doc slot in the next task of this
iteration (decision logged on the issue).
refs #316
C29 compile/unit seam, tasks 6-10 -- iteration 1 of the self-description
plan complete: every engine-shipped vocabulary entry now carries a
gate-clean one-line meaning.
- aura-runner: the internal tap recording sink threads its doc (the
last unthreaded NodeSchema site) -- first full workspace build since
the field became required.
- aura-cli scaffold: the sample node's template carries a doc line plus
a maintenance comment, so every scaffolded extension crate starts
gate-clean; both extension-vocabulary fixture exemplars thread real
meaning lines (the load seam walks these in iteration 2). New E2E:
the scaffold's own doc must pass its own gate -- an alibi doc in the
template would teach the wrong pattern to every new project, and the
compiler checks only the field's presence, never its shape.
- aura-research: metric_vocabulary()/tap_vocabulary() promote from bare
name arrays to MetricSchema/TapSchema carriers (id + doc, 17 + 4
authored lines); callers adapt to .id with byte-identical output
(introspection goldens unchanged). The #190 guard keeps its triple --
the doc column adds no fourth roster site.
- Coverage: tests/self_description.rs walks all five vocabularies
(blocks, metrics, taps, folds, std nodes) through doc_gate -- the
guard that keeps any future edit from blanking a doc.
Adjudicated review residue: the 17 metric doc strings are surfaced by
no CLI path yet -- deliberate; task 8 pins callers byte-identical, the
surfacing belongs to the CLI self-description work (#315). Plan-cited
coordinates lib.rs:1003/:1283 resolved to the real caller sites
(:1019/:1299); the plan's literal test code was reconciled to the real
accessors (FoldRegistry::core().roster(), Env::std()).
Gates: cargo test --workspace green (0 failed, incl. the new coverage
walk + scaffold E2E); cargo clippy --workspace --all-targets --
-D warnings clean.
refs #316
Every hand-rolled test-sandbox helper keyed its directory on
std::process::id() under env::temp_dir(), so the pre-create wipe never
matched a prior run's path: one directory stranded per helper site per
test-binary invocation, >50k dirs / 15.5 GiB on the 16 GiB tmpfs by
2026-07-13.
The remedy extends commit 84e1075's knob-lab pattern to every site:
fixed, tag-keyed, PID-FREE names under the build-tree tmp anchor, each
site keeping its pre-create remove_dir_all — which now genuinely
reclaims the previous run. Integration/bench targets use
env!("CARGO_TARGET_TMPDIR"); src-internal unit-test helpers (cargo sets
that var only for integration/bench targets) derive the same anchor
from env!("CARGO_MANIFEST_DIR") + ../../target/tmp. Residue is bounded
to one directory per site, on disk instead of the tmpfs, per checkout.
One deliberate exception: project_new.rs's tmp() stays under
env::temp_dir() because two of its tests (new_outside_a_work_tree_*)
need a base genuinely detached from any git work tree, and target/
lives inside the checkout's work tree. Its name carries a per-checkout
hash discriminator instead, so concurrently running checkouts (which
share /tmp) cannot race on the fixed name while each run still
reclaims its predecessor.
tempfile-RAII was considered and rejected (issue #258 decision log):
it cannot cover the process-lifetime OnceLock scaffolds (statics never
drop), adds a dependency, and still strands kill-leftovers on the
tmpfs.
Verified: full workspace suite green (incl. the new RED regression
test temp_cwd_sandbox_does_not_leak_under_env_temp_dir), clippy clean,
sandboxes observed under target/tmp with stable names across runs.
Stale pre-fix PID-keyed dirs in /tmp are not swept by this change and
age out only by manual cleanup.
closes#258
Task 6 of the bound-override cycle: SIGNAL_OPEN_JSON_STD and its write
retire — aura new scaffolds signal.json alone, and the project CLAUDE.md
quickstart advertises run AND sweep against that one file (the sweep line
overrides the bound fast.length; --list-axes shows open + bound axes).
The data-only e2e loop proves it end to end: scaffold, run the closed
starter, sweep it via an override axis, and assert signal.json is the
only starter blueprint. The authoring-guide's starter-pair sentence is
retargeted; the last signal_open reference outside the unrelated #196
fixture string is gone.
refs #246
aura new and aura nodes new follow their git init with a best-effort
initial commit (inline committer identity, warning-never-fatal, skipped
whenever the init itself was skipped per #204), so a fresh project's
first run stamps a real commit instead of an empty provenance block.
closes#243
- New clap family `aura nodes new <name> [--engine-path] [--namespace]`:
scaffolds a node crate as a SIBLING of the project root (Cargo.toml
with the aura-core path-dep, the parameterized Scale starter node,
roster macro, crate-scoped .gitignore + CLAUDE.md, own git repo) and
appends the `[nodes] crates = ["../<name>"]` pointer to the project's
Aura.toml. Refuses outside a project, on any existing [nodes] section
(incl. an empty crates array), and on an existing destination; joins
the load-phase bypass beside `aura new` (a scaffolder must work in an
unbuilt tree).
- The old single-tier scaffold() is gone; the crate templates live on
in scaffold_node_crate; dead-code bridges removed with their callers.
- tests/project_nodes.rs: attach + refusals + namespace override + the
full role-2 loop (scaffold, cargo build, vocabulary resolves
<ns>::Scale end to end).
- tests/project_sweep_campaign.rs fixture reworked to the two-tier
shape (aura new + aura nodes new --namespace knob_lab); the two
campaign acceptance tests are byte-unchanged and green.
refs #241
- NewCmd drops --engine-path/--namespace (they belong to the node-crate
scaffold); dispatch_new emits Aura.toml + .gitignore + two std-only
starter blueprints + CLAUDE.md, git init, no crate, no build step.
- Two starter blueprints because run requires a closed blueprint while
sweep requires open knobs: signal.json (closed, run target) and
signal_open.json (fast.length free) — the scaffolded CLAUDE.md
quickstart lines are both verified live.
- The crate templates survive untouched for the attach verb; old
scaffold()/scaffold_spec() carry a dead-code bridge until it lands.
- project_new.rs realigned: data-only file set, no-build run headline
(stdout report, C1 byte-identity, commit-only provenance, negative
runs/ assert), advertised-sweep headline (#218 gate passes, store
lands project-local).
refs #241
The `aura new` scaffold shipped one node, a param-less Identity, so a
downstream author had no public example of a build closure consuming a
bound param — the highest-value gap the project-environment fieldtest found
(F2): a newcomer could copy a param-less node but had to read engine source
to write their first *tunable* one, which the consumer contract forbids.
Swap that single starter node for a Scale node (mirroring the std gain
operator): its schema declares a `factor` ParamSpec and its build closure
reads the bound value (`|p| Box::new(Scale::new(p[0].f64()))`), and the
starter blueprint binds `factor` so `aura run` exercises the bound-param
path with zero hand-editing.
factor is bound to 1.0 — a neutral identity default the newcomer then tunes,
not the only C7-safe value (only |factor|>1 would push the terminal `bias`
output past the bounded [-1,+1] contract; the knob is genuinely read and
multiplied each cycle). The param-reading closure is the copyable template
content #183 delivers; a hypothetical `|_|` regression is caught by the
scaffold unit test's source guard, and tests/project_new.rs re-validates the
swap by building and running the scaffold end to end.
Template-side only (#181): the frozen 0102 demo-project fixture is untouched.
closes#183
The `aura new` scaffold ships one node, a param-less Identity, so there is
no public example of a build closure consuming a bound param — the F2 gap
the project-environment fieldtest rated its highest-value authoring miss.
This pins the target: the rendered starter lib.rs declares a ParamSpec and
reads p[0] in its build closure, and the starter blueprint binds `factor`
on the project's own node, so `aura run` exercises the bound-param path
with zero hand-editing.

MILESTONE VERDICT: GREEN — the whole span (0106-0109) holds end to
end as one continuous consumer scenario: authored from a bare {} via
introspection alone, every ref resolved from the public surface, three
validation tiers, run by content id over two real instruments through
the full v2 pipeline, realization recorded (selection/survivors/
bootstrap/generalizations/trace_name), traces on disk and charted,
read back via campaign runs, byte-identical re-runs (C1), refusals
precise. 0 bugs, 0 frictions, 0 spec gaps; 2 doc-gaps.
F7 fixed in this commit (the docs claimed an archive-root path without
naming the key; a guessed [paths] archive silently no-ops): project-
layout and the glossary Aura.toml entry now name [paths] data, and the
aura new template advertises the commented-out key. F8 (op-script
grammar not CLI-discoverable) filed as #208, sibling of the #197 docs
half — one docwriter pass once desired.
The milestone-close gate evidence is this corpus; the formal milestone
close and the push remain user-reserved.
refs #189
The cargo-new mirror completed: a scaffold landing inside a tracked
tree no longer nests a .git (the gitlink/submodule hazard that bit the
fieldtest corpus); outside a work tree the best-effort init is
unchanged. Oracle: git rev-parse --is-inside-work-tree in the target
dir; any failure reads as not-in-a-work-tree so the init stays
best-effort.
RED-first (tdd-author handoff): the inside-a-work-tree pin observed
failing on the nested .git; the outside guard pinned against
over-removal.
Gates: workspace 1003/0, clippy -D warnings clean.
