Source-blind per-cycle fieldtest of the #317 surface (register->label->
discover->use loop; ref forms + refusal UX; open patterns; sweep axes through
a spliced instance). Corpus under fieldtests/composites-use/ with TRANSCRIPT.md.
Working: the full authoring loop (W1), ref-form variety incl. ambiguous/
unknown-prefix and unknown-label refusals (W2), sweep --list-axes and a real
sweep through graph.<instance>.<node>.<param> plus splice-time bind (W3).
Findings, routed at close:
- B1 (reclassified: docs untruth, behaviour ratified): an open pattern whose
input role names an archive column RUNS standalone — the harness binds
roles by name, which is C26's design; the "running standalone refuses"
claim was the wrong sentence, fixed in the follow-up docs commit and
minuted on #317.
- S1: the run path's actual refusal trio (bias/tap gate, free knobs, role-
column) vs the docs' bootstrap-gate story -> same docs commit + #339 note.
- F1: gang-on-instance-member refusal does not name the unsupported-rule ->
evidence added to #339 item 1.
- S2: README still enumerated nine ops -> fixed in the follow-up commit.
- S3: the use-seam C29 gate is unreachable through today's CLI writes
(register gates both input forms) -> ratified as a backstop, one line in
C24.
- Orthogonal pre-existing observation (NOT #317): aura run --params did not
close free knobs in the fieldtester's hands -> #340.
