Resolves the actionable drift the cycle-close architect review found:
- Ship registry.toml (the spec's acceptance artifact) for aura + data-server,
so `docsite serve`/`check` run out of the box — the headline live-render was
not runnable as shipped without it.
- Cache before fetch: the page handler now resolves the branch SHA, serves
from cache on a hit, and only fetches the source on a miss (the spec
data-flow). The pre-tidy handler always fetched, paying a wasted Gitea read
on every cache hit. A new e2e test (a counting fetcher) pins that a second
request serves from cache without re-fetching.
- Escape the registry slug/page in nav_html's href and the index links —
operator-trusted data, but consistent with the documented no-injection
invariant and the rest of the shell (which already escaped).
cargo test green (41: 32 lib + 8 e2e + 1 gated live smoke); clippy clean.

The first runnable DocSite server (plan docs/plans/0001-walking-skeleton.md):
`docsite serve` renders the published docs of aura and data-server live from
their Gitea main revisions, dark-themed, navigated from the DocSite-owned
whitelist registry; `docsite check` validates every nav reference against the
live sources with an exit code. Built across nine TDD tasks — config (registry
whitelist + traversal guard), gitea read-only client (Fetcher trait, injected
for offline tests), render (comrak GFM + syntect), theme (embedded dark CSS +
shell), revision-keyed cache, reference validator, axum server, main wiring.
All five domain invariants land: read-only Gitea access via the Fetcher trait;
single source of truth via the (repo,path,sha) cache; reference integrity
detected (check + a fail-loud render-time error block) never enforced;
whitelist publishing with path-traversal refusal; the closed directive
vocabulary's no-op expansion seam reserved in render.
Verification (run by the orchestrator): cargo build green; cargo test green —
40 tests (32 lib unit + 7 e2e via an injected MockFetcher + 1 gated live smoke
that reached the real Gitea this run); cargo clippy --all-targets -D warnings
clean.
Held quality findings (plan-prescribed / plan-deferred, not defects; tracked
as follow-up issues): nav_html interpolates the registry slug/page into the
href unescaped (operator-trusted registry — latent, not a live vector);
GiteaClient's 404->NotFound status mapping (the invariant-3 broken-reference
signal) is covered only by the gated live smoke's happy path, not a unit test.
Resolved API deviations from the plan text (newer crate versions): reqwest
0.13 renamed feature rustls-tls -> rustls; comrak 0.52 deprecated `Plugins`
(used `comrak::options::Plugins`); axum 0.8 capture syntax `/{slug}/{*page}`.
