Merge Risk: 🔵 Low · up to Document intake and PDF rendering are additive features with bounded inputs. One memory-efficiency gap remains: many near-empty sections can each keep large unused buffers. It is a bounded issue that should get a quick follow-up fix. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The new APIs enforce substantial input and output limits and reuse the existing cleanup model. However, PDF rendering adds complex processing inside the host process without a hard execution or total-memory budget. Caller timeouts do not stop that work. This creates a meaningful availability risk whose effective exposure depends on host authorization and resource isolation. Retained concerns

Addressed the current Rust and supply-chain failures in 5f89928: upgraded direct quick-xml intake parsing from 0.38 to patched 0.41 (RUSTSEC-2026-0194/0195), adapted attribute decoding without suppressing deprecations, and changed the raster test to array chunks accepted by current stable Clippy and Rust 1.88. Also added allocation regressions and linked specification/plan documentation requested by review. Fresh |

Dismissing this stale changes-requested verdict after addressing its sole inline finding in 5f89928: xml_text now shrinks its returned buffer, with a regression test. CodeRabbit explicitly acknowledged the fix in the resolved inline thread. The PR was re-requested for review; the latest CodeRabbit status is rate limited, and the exact final head has passing CI plus an independent review approval. No actionable threads remain.

Update the pre-existing documentation alongside these new handlers: docs/specs/tinybus-module.md:38-46 still defines the accepted interface as five methods and omits ExtractDocument and RenderPdf, while README.md:183-194 still says every feature is enabled by default and lists neither optional feature. These conflicting contract descriptions can cause hosts to implement the obsolete surface despite the newly added specification.

Add a rationale immediately above this new dependency explaining that the module E2E test constructs a DOCX fixture. The adjacent comment applies specifically to serde_json, so the newly introduced zip entry currently lacks the repository-required dependency justification.

Add document intake and selective PDF rendering for hosts that retain original uploads. PDF output preserves page provenance and scanned-page candidates; DOCX/PPTX/XLSX extraction follows document relationships and returns bounded section text. Selected PDF pages produce held PNG outputs with pixel/output limits and rollback on partial allocation failure.
Office ZIP metadata is admitted before eager indexing, duplicate raw names are rejected, and XML output bounds apply during shared-string expansion. Existing methods and bus contract version 2 remain compatible; new methods are additive. Hosts must detect availability on older modules.
Validation (fresh, all pass, run from this repository root):
cargo test --workspace --all-features cargo clippy --workspace --all-targets --all-features -- -D warnings cargo +1.88.0 check --workspace --all-features cargo deny --all-features check all cargo fmt --all -- --checkRegression coverage includes shared-string record/text budgets and short-section retained capacity. The intake dependency uses patched quick-xml 0.41; advisories remain enforced. Earlier validation also covered feature-disabled/intake-only tests and dynamic-module broker E2E.
The module runs in-process. PDF parser/renderer internals have no global allocation budget, and a caller timeout does not cancel blocking parsing. Input/page/pixel/output limits are documented.
Dependency for tinyhumansai/openhuman#6964. OpenHuman requires a published module release and its published checksums before enabling these new methods in its pinned runtime.
