The campaign half of research_docs.rs: validate (intrinsic always;
referential tier when a project env is discovered, with the explicit
skip line outside one), introspect (--vocabulary/--block/--unwired/
--content-id, same exactly-one-of usage guard), register via the
registry's campaign_path accessor, and RefFault prose (Display-free,
unit-pinned). Five binary seam tests (skip line, empty-axis prose +
exit 1, section vocabulary, spec-example open slots, content-addressed
registration) reuse the file's temp_cwd helper — the plan's
tempfile::tempdir() snippet deviated from the crate's zero-extra-dep
test convention and was adapted, disclosed in the loop's report.
The referential CLI branch inside a real loadable project stays
fieldtest territory by the plan's own scope note (project::load needs a
built dylib); its logic is pinned by the aura-registry tests.
Gates: cargo test --workspace 916/0 (885 pre-cycle + 31 new), clippy -D
warnings clean, cargo doc --no-deps 0 warnings. The worked spec example
runs end-to-end headless: author both documents as text, validate with
per-tier report lines, introspect vocabularies and open slots, obtain
stable content ids, register into the store — no Rust compile, no run
executed.
closes#189
New research_docs.rs module: role-addressed process verbs with house-style
fault prose (Display-free enums phrased at the seam), the introspect
exactly-one-of usage guard (exit 2), and content-addressed registration.
Seven binary seam tests pin intrinsic-ok/refusal prose, vocabulary/block/
unwired/content-id introspection, exit codes, and the stored file's
location under the runs root.
Quality-gate finding folded in (and back into the plan): register no
longer re-derives the store path from runs_root — aura-registry now
exposes process_path/campaign_path, the same single mapping its put/get
pair routes through, so the printed path cannot drift from the store
layout.
Verification: research_docs seam tests 7/0, registry 49/0, clippy clean.
