Brummel ad83a4b170 fieldtest: milestone project-environment — GREEN (authoring loop end-to-end from public docs)
Milestone-close gate for 'Project environment — the project-as-crate
authoring loop' (#180), run as a downstream consumer from the public
interface only (README, project-layout, glossary, ledger, --help; no
crates/*/src, no crates/*/tests). Verdict: GREEN — 0 bugs.

Tasks (all ran, evidence in the corpus): (1) aura new -> cargo build ->
run twice byte-identical -> manifest project provenance
{namespace, dylib_sha256}; (2) a REAL authored node (Negate) in the
scaffolded lib.rs -> rebuild -> graph build resolves the project type ->
run flips total_pips sign, dylib_sha256 tracks the fresh build; (3)
renamed-twin id semantics: content-ids differ, identity-ids equal,
combinable output content-first, content-id == manifest topology_hash;
(4) misuse paths: charter violation named + refused exit 1,
missing --release build names path + fix, outside-project refused.

Findings (non-blocking, triaged separately): F1 friction (aura new git
init nests a gitlink under the engine tree), F2 doc-gap (no public
example of a bound-param build closure — the Identity template is
param-less), F3 doc-gap (glossary manifest entry lacks the project
provenance block), F4 friction (run leaks raw UnknownNodeType Debug
where graph build phrases house-style), F5 doc-gap (outside-project run
surfaces UnknownNodeType instead of a no-Aura.toml hint), F6 doc-gap
(scaffolded Aura.toml omits the documented data-archive-root key).
