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.
