SubmitDocParserJobAdvance uploads PDFs to Aliyun OSS via tea/httpx, which
defaults readTimeout to 3000ms when RuntimeOptions is empty. Multi-MB
teacher PDFs on para silo failed with ReadTimeout(3000) before the job
could start. Set connectTimeout=15s and readTimeout=5m.
createReadStream emits async ENOENT without a listener, which became an
unhandled 'error' event and exited the silo process. Teachers then saw the
startup "process restart" notice. Wait for stream open and convert missing
files into DocmindClientError instead.
pbank materialize previously shelled out to `unzip` and soft-failed when
the binary was missing, so agents only saw titles. Read zip entries with
Node zlib (store/deflate) and write under workspace .pbank-sources.
Register pbank as an ADR-0027 external capability with org-scoped
username/password envelopes, readiness via /login, and in-process
cph_hub MCP tools (search/get/get_many) that materialize sources under
the run workspace. Extend the capability secret payload for docmind vs
pbank kinds, admin capabilities UI, role tool umbrella `pbank`, and the
pbank-problem-report skill. Credentials never reach the Agent process.
Teachers convert many PDFs in one tool call with bounded Docmind concurrency.
Each item keeps its own output_dir/document.md and UsageFact; failures are
per-file. Mirror role skills to .cph/runtime-skills and CPH_RUNTIME_SKILLS_DIR
so agents can Read SKILL.md instead of dead .claude/sandbox stubs.
