fix(memory): read PDF, Word, PowerPoint and Excel into the brain (#7023) - #7034
Conversation
…yhumansai#7023) memory_brain_ingest and file-backed sources converted only through NativeConverter, so a PDF was refused on production with "the native converter does not handle pdf; bind a converter that does". TinyMemory ships OfficeConverter (PDF/DOCX/PPTX/XLSX) behind `documents-office` for a host to prepend. Enable it and convert through one chain, office first then native, with office parsing on the blocking pool so a large PDF does not stall a runtime worker. Also pins two tinyhumansai#7023 criteria with tests: the per-turn memory pack never rewrites the cached prompt prefix across turns (default and hoisting placements), and a pack stays within budget_tokens over a 1,500-item store.
Tiny Sweeper reviewTiny Sweeper reviewed this change across 6 lane(s) and found 1 active actionable finding(s). The change adds an office/PDF document conversion path to memory: a new `memory::convert` module wires TinyMemory's `OfficeConverter` (PDF, DOCX, PPTX, XLSX) behind the existing `documents` feature through a blocking-pool adapter, and both brain ingest and file-source sync now convert through the shared converter chain. Supporting tests cover PDF conversion, brain ingest of a PDF by path, refusal without the feature, and prompt-cache stability of the per-turn memory pack. One medium finding remains: the reasoning-hint test opens a real local network socket. State: Reviewing pending checks Review snapshot

Add the missing convert module source
Rust resolves this declaration to crates/openhuman-core/src/memory/convert.rs or crates/openhuman-core/src/memory/convert/mod.rs, but neither file is present in the reviewed diff or tree. The crate therefore fails with a missing-module-source compilation error; add the intended module file or remove this declaration.

False positive: crates/openhuman-core/src/memory/convert.rs (and convert_tests.rs) are added in 7f63db3 (git show --stat 7f63db3984 lists A crates/openhuman-core/src/memory/convert.rs). CI compiled the crate and ran memory::convert::tests::* on that commit; they pass with and without the documents feature.

CI's kernel floor failed: enabling tinymemory's `documents-office` on the always-on path grew the flows profile from 328 to 367 packages. Office parsing now rides the existing `documents` feature (already in the shipped product set and forwarded through embed, tinyhumans, cli and the app). Without it memory::convert is native-only and a PDF is refused cleanly (new test), as before tinyhumansai#7034. Also ratchet the kernel floor to 328/307: origin/main already resolves 328 packages / 307 names, below the 332/311 limit, so every Rust PR failed "IMPROVED but was not ratcheted". This PR adds nothing to that profile.

Add the missing convert module source
The earlier critical finding still stands: this revision only changes the dependency-floor entry and does not add the missing convert module source. If the module is still declared or referenced without its source, the Rust build remains broken for every consumer. Add the module implementation (or remove the declaration/reference) before lowering the floor.

Add the missing convert module source
The documents feature now forwards tinymemory-integrations/documents-office, but the repository contains no corresponding feature or memory::convert implementation in the vendored integration. Enabling the default documents configuration therefore cannot resolve the feature/module required by this manifest. Add the integration and its convert module, or remove this feature forwarding until the dependency is available.
Additional critique observation
Add the missing convert module source
[RULE] missing-module
This remains unresolved from the prior review. With the documents feature enabled, crates/openhuman-core/src/memory/sources/sync.rs calls crate::memory::convert::converter(), but no memory::convert source or module declaration was added in this change. Documents-enabled builds therefore fail to resolve the module. Add the conversion module and wire it into the memory module before enabling this feature.
[RULE] missing-module-source ·
There was a problem hiding this comment.
False positive: the feature exists in the vendored crate. vendor/tinymemory/crates/tinymemory-integrations/Cargo.toml line 119: documents-office = ["documents", "dep:pdf-extract", "dep:calamine", "dep:quick-xml", "dep:zip"], and tinymemory_integrations::documents::OfficeConverter is exported from src/documents/mod.rs:66. memory::convert is the host module added here. Verified: cargo test -p openhuman --lib --features documents -- memory::convert passes (4 tests), and so does the build without documents (3 tests).

Keep the calibration count aligned with the unchanged dependency graph
This pull request changes only the expected count; it does not change the dependency graph that dep-sim.py --cut-nothing measures. The previous threshold was 311, so lowering it to 307 will make the calibration lane fail whenever the unchanged graph still produces 311 names. Restore the existing threshold or include the dependency changes that actually produce 307 names.

Correct. 307 came from a local macOS measurement; CI's Linux toolchain resolves 311. Reverted in 375f447 (EXPECTED_NAMES=311, kernel floor back to flows:332:311:3). With the office parsers behind documents, this PR adds nothing to that profile.

Avoid real network sockets in the reasoning test
This unit test binds a TCP socket and then exercises the backend through an HTTP request. The repository rules prohibit real network access in tests, even when the peer is a local capture server. Replace the socket-based capture with the repository's mock backend/test harness so the test remains deterministic and does not depend on networking.

This test is unchanged: the section was moved verbatim from openhuman_backend_model_tests.rs on main (it was 760 lines, over the 750-line rust-layout limit that failed CI on every PR). git diff origin/main --color-moved shows it as a pure move. The capture server binds 127.0.0.1:0 (loopback only, no external network), the same pattern stream_tests uses. Changing the test's design is out of scope for a move; it belongs with the test's owner.

Avoid real network sockets in the reasoning test
This test binds a real TCP listener on the loopback interface and serves HTTP over sockets, which is exactly what the repo rule forbids in unit tests: avoid real network access. A mocked provider or in-memory transport for the backend would test the same reasoning-on-wire behaviour without sockets, keeping CI hermetic. The rest of the test suite uses a shared mock backend for this reason (scripts/test-rust-with-mock.sh). Keeping severity from earlier revision (medium) since the change is unchanged; nothing has moved to lower it.
