#163 — the construction op-script (`aura graph build`) had no durable public
schema doc, and the only worked-example corpus had drifted out of sync with the
current binary, so a consumer copying the visible example was misled.
Grammar reference (durable): a compact op-script grammar — the six verbs
(source/input/add/feed/connect/expose), their keys, the typed-Scalar bind form
({"I64":2}) and the capitalized ScalarKind, the by-identifier / dotted-port
model, and the add-`name` vs expose-`as` distinction — added to the C24 ledger
entry, with a correct worked-example pointer. Surfacing the same grammar in
`aura graph build --help` is left to ride with the CLI-discoverability work
(#159), keeping this change decoupled from the deferred World/project-as-crate
layer.
Corpus refresh: the cycle-0088 fixture corpus replayed against the current
binary failed on two accumulated drifts. (1) `add`'s naming key was renamed
`as` -> `name` (3c4b667; `expose` keeps `as` as a real alias) — the inputs now
use `name` for `add` ops only. (2) The dataflow-cycle bug the 0088 fieldtest
found was fixed (1652042, closes#161), so `c0088_3m_two_cycle` is now a
rejection fixture: the gap-era cyclic-blueprint golden is removed and
`c0088_3m.err` carries the eager cycle-rejection message. FINDINGS.md gets a
dated refresh stamp; its findings are preserved as written at fieldtest time.
Verified: the four golden-bearing success fixtures (_1, _2_completed,
_2_partial via --unwired) reproduce byte-identically; all 15 error fixtures
produce the intended by-identifier `op N (kind): cause` (or finalize) message.
Doc + fixtures only, no engine/CLI code touched.
closes#163
Exercise the construction op-script service (#157) purely as a downstream
consumer authoring topology as data: discover-then-author an SMA-crossover
bias, author-with-`--unwired`, and 15 error-ergonomics fixtures. Public
interface only (the C24 ledger + the CLI's own output); no implementation
source read.
Confirmed working: discover→author round-trip, the `--unwired` by-identifier
authoring aid, eager per-op diagnostics. Surfaced one bug + frictions, all
reproduced and filed forward:
- #161 (bug): `graph build` accepts a dataflow cycle — DAG invariant 5
unenforced; reproduced directly before filing.
- #162: construction error/bind ergonomics (raw-index finalize, Debug-struct
bind-mismatch, undiscoverable typed-Scalar bind).
- #28: no CLI consumer for the emitted #155 blueprint (round-trip dead-ends).
- #159: construction surface undiscoverable from the CLI usage/help.
FINDINGS.md carries the full report + the triage table. The two 1.4 MB
self-contained viewer HTML dumps from the round-trip check are dropped as
bloat (the byte-identical result is recorded in FINDINGS).
