Manually tested all three new RPC methods against a running server instance.

bun run buildexits with SIGABRT after successfully generating the static files. This is a known bun runtime issue, not related to this PR. The build output is complete and valid.Review
The PR matches issue #92 on the mechanical bits — dep added, three methods wired, in-memory job registry, dedup by input hash, generated client and inline schema updated. Parallel jobs for distinct inputs work. Happy to merge this as a stepping stone so callers can start using the RPC shape.
Required follow-ups before/after merge
Add a smoke test that exercises
docs.new→docs.jobStatuspolling end-to-end. Issue #92 explicitly asked for this. The two unit tests (test_docs_job_registry,test_docs_job_dedup) only poke theHashMapdirectly — they never go through the RPC handlers, so a bug in the handler layer wouldn't be caught.Collapse the dedup logic to the already-exported helper.
find_running_docs_jobis exported fromserver.rsbut bothhandle_docs_newandhandle_docs_generatere-implement dedup inline. The two paths also have slightly different semantics: the inline version dedupsDonejobs too, the helper only dedupsPending | Running. Pick one policy and use the helper from both handlers.docs.generateshould also accept a book id, not only a heroscript path. Issue #92 said "from an existing book (by book id or path)." Current impl only acceptspath. Minor, but worth closing the gap.std::thread::spawnvstokio::spawn. The issue specifiedtokio::spawn. For a build that shells out to bun, OS threads are defensible, but call it out in a comment so the next reader knows it was deliberate.Architectural follow-up (separate issue, not blocking this PR)
After #92 was filed we agreed the Hero-native shape is to run docusaurus generation as a hero_proc action, with
docs.*methods creating and polling runs of that action. This PR keeps jobs insidehero_books_serverwith an in-memory registry, which means:The external RPC shape (
docs.new,docs.generate,docs.jobStatus) can stay stable when the guts are swapped, so this doesn't need to block merge — but please open a follow-up issue titled something like "Migrate docs.* jobs to hero_proc actions" and link it here.Bottom line
Merge once (1) and (2) are addressed — (3) and (4) can fold in, (5) becomes a new issue. The RPC surface is good; the internals are the part that needs to evolve.
Delete the in-memory DocsJob / docs_jobs() registry and submit each docs.new / docs.generate call as a hero_proc job via HeroProcRPCAPIClient. The server no longer owns job lifecycle state; hero_proc does. Why: - job state now persists across restarts - cancel / retry / logs / listing via hero_proc's native APIs - docs jobs show up alongside other Hero work in admin UIs - removes duplicate infrastructure Shape: - docs.new / docs.generate build an ActionSpec whose script shells out to the sibling `hero_docs` binary (resolved from current_exe().parent(), matching the hero_books service registration convention). The action is tagged `docs#️⃣<input_hash>` so the next call with the same inputs deduplicates via job.list(tag = ...) — no local HashMap needed. - docs.jobStatus parses job_id as i64, calls job.status, maps hero_proc phases (pending|waiting → pending, running|retrying → running, succeeded → done, failed|cancelled → failed), and for failed jobs pulls the last ~10 log lines via job.logs. - output_path is deterministic: get_docusaurus_cache_dir()/<hash>/build. Recovered from the job's tags in docs.jobStatus. ServerConfig gains hero_proc_socket (env HERO_PROC_SOCKET, default ~/hero/var/sockets/hero_proc/rpc.sock) and hero_docs_bin (sibling to the running server binary). Populated once in main.rs. Tests: removed the six tests that relied on the in-process background thread (they'd now need a live hero_proc). Kept the four input-validation tests that short-circuit before any RPC call, and added unit tests for the new pure helpers (map_hero_proc_phase, shell_quote, calculate_docs_input_hash). 16 tests still pass.

47039e5)First pass of live testing showed identical
docs.newcalls were producing new ids (821 → 822). Root cause: hero_proc does not currently persistActionSpec.tagsonto the job record — everyJobSummary.tagscame backnull, so thefilter.tagquery silently matched nothing.Fix: switch dedup to
filter.action_id, which equals the action name we construct from the input hash, and is always persisted. Same fix applied to theoutput_pathrecovery indocs.jobStatus— it now parses the hash out ofsummary.nameby stripping thedocs_new_/docs_generate_prefix.Also switched to using the full input hash in the action name (was a 12-char prefix) to rule out theoretical collisions and keep the name ↔ hash round-trip exact.
Cross-checked against hero_proc directly
Jobs show up under hero_proc's normal
job.list/job.status/job.logssurface, which was the whole point of the refactor.Outstanding
Not blocking this PR:
hero_docs new --pathnesting bug still untouched.service_books.nu installpriming of the docusaurus template still pending..env("PATH", …)/.env("HOME", …)on the submitted spec.ActionSpec.tagsaren't propagated toJobSummary.tags. Not our bug; worth filing against hero_proc so admin UI tag filtering works in future. We're now usingaction_idinstead, so not blocked.Recommendation
From my side this PR is merge-ready. External RPC surface is stable, all four behaviours validated live, 16 unit tests green, net ~200 LOC deleted overall vs the original in-process design.
