The cycle-0088 fieldtest found three presentation defects on the construction
op-script surface, all where the surface dropped out of its by-identifier register.
Presentation only — every fault still fires identically (same exit code, same
op/finalize attribution); only the rendered cause changes.
- Item 1 (finalize by-identifier). The holistic finalize fault leaked the raw
index Debug form (`UnconnectedPort { node: 2, slot: 1 }`). `GraphSession::finish()`
now translates the three reachable index-carrying CompileErrors into new
by-identifier OpError variants (UnconnectedPort{node,slot} / RoleKindMismatch{role}
/ UnboundRootRole{role}) using the session's `ids`/`schemas` and the composite's
`input_roles()` — the holistic gate calls (validate_wiring,
check_param_namespace_injective, check_root_roles_bound) stay byte-for-byte
unchanged (C24: no second validator; only the `.map_err` closures changed).
`aura graph build` now prints `finalize: slot sub.rhs is unconnected`.
- Item 2 (bind mismatch prose). `format_op_error`'s BadParam arm matches the
BindOpError variants instead of `{:?}`: `op 1 (add): param fast.length expects I64
but got F64`, matching the connect mismatch register.
- Item 3 (discoverable bind form). `introspect --node` shows the typed-Scalar bind
form: `param length:I64 (bind {"I64": <v>})`.
Item 1 spans both crates atomically (adding OpError variants forces the exhaustive
format_op_error match; the finish() translation flips behavioural test pins in both
crates). Five test touches: the two in-file unit tests, the two E2E twins plan-recon
found that the spec's testing strategy under-enumerated
(construction_e2e.rs, tests/graph_construct.rs), and a new unbound-root-role test;
the implementer added RoleKindMismatch / Ambiguous/UnknownParam coverage too. The
CLI finalize test was tightened (orchestrator) to pin `sub.rhs` and the absence of a
raw `node:` index.
Spec boss-signed on a grounding-check PASS (docs/specs+plans/0089). Verified: full
workspace suite + clippy green; the three messages reproduce exactly against the
built binary on the fieldtest fixtures.
Iteration-1 §B of the construction service (#157), on the §A shared predicates
(ea1ca32): a declarative, replayable by-identifier op-script that builds a
runnable blueprint through validated ops, reusing the engine's existing gates at
two cadences — no second validator (C24).
- construction.rs: `Op` (Source/Input/Add/Feed/Connect/Expose, 1:1 with the
document, dotted by-identifier ports), `OpError` (by-identifier causes),
`GraphSession` (per-op-fallible accumulator) and the free `replay` driver
(stop-at-first-failing-op, naming it by `(op_index, OpError)`).
- Eager (per-op): name resolution + edge_kind_check + the >1-cover
DoubleWiredPort arm + try_bind — all calling the §A shared predicates.
- Holistic (finish): the 0-cover totality arm, param-namespace injectivity, and
root-role boundness — the SAME unchanged engine gates
(check_param_namespace_injective / validate_wiring), now at end-of-document.
- Build-free introspection: `unwired()` (a partial document's still-open slots).
- aura-std std_vocabulary_types(): the enumerable companion to the closed
std_vocabulary match (a `fn(&str)->Option<…>` resolver cannot be listed),
lockstep-tested in the list->resolver direction; the reverse fails safe (#160).
- aura-engine exports replay/GraphSession/Op/OpError + re-exports BindOpError.
Acceptance (engine level): a sink-free price->fast/slow SMA->Sub->Bias signal
root built through the ops compiles to a FlatGraph byte-identical (edges +
sources) to its GraphBuilder twin (C1); an invalid op is rejected at the op,
named; vocabulary + unwired slots answer without a build. Pinned by
construction.rs unit tests + a construction_e2e.rs integration test over the
public seam the iteration-2 CLI will consume.
Notable judgement calls folded in from the implement loop: feed is all-or-nothing
(two-phase resolve-then-commit, no partial wiring on a mid-fan-out fault); the
node identifier is stamped onto the builder (`named(&id)`) so two same-type nodes
get distinct param paths and do not trip the injectivity gate prematurely; a
module-level `#![allow(dead_code)]` covers the public surface until the
iteration-2 CLI consumes it. Full suite green; clippy --all-targets -D warnings
clean.
Iteration 2 (the JSON op-list encoding + `aura graph build`/`introspect` CLI)
remains; #157 stays open. refs #157
