Summary

Expand the memory contract into four capability-gated ingestion routes—documents, conversations, learnings, and raw events—and two retrieval routes: recall and agentic answer. Add a high-level router, rich wire types, adapter capability negotiation, full TinyCortex coverage, conversation ingestion for Mem0, and TinyBus module dispatch for the new operations.

Related issue

None.

API or behavior changes

Additive public API change. Adds MemoryDocumentIngest, MemoryConversationIngest, MemoryLearningIngest, MemoryEventIngest, and MemoryAnswer, plus their request/response types and MemoryApi routing facade. The bus contract advances from 3.0 to 3.1 and appends capability bits without reordering existing values. Unsupported adapter routes return the corresponding typed capability error.

Validation

Commands actually run, with their outcome:

  • cargo fmt --all -- --check
  • cargo clippy --all-targets --all-features -- -D warnings
  • cargo build --all-targets --all-features
  • cargo test --all-features
  • cargo clippy --all-targets --all-features -- -D warnings in crates/tinymemory-module
  • cargo test --all-features in crates/tinymemory-module
  • RUSTDOCFLAGS="-D warnings" cargo doc --no-deps --all-features
  • git diff --check

Tests

Adds and updates capability, routing, adapter, conformance, persistence, and TinyBus manifest/dispatch tests. Live network and live language-model calls remain intentionally excluded; the native HTTP test double and host-provided runtime seams cover deterministic adapter behavior.

Documentation

Adds docs/specs/ingestion-retrieval-api.md, including operation semantics and the adapter capability matrix, and updates the root and bus READMEs.

Checklist

  • The change is focused on one logical change
  • No new #[allow(...)], #[ignore], or relaxed lints
  • No secrets, tokens, or .env contents in the diff or the description

The absent route test now uses a match instead of expect_err, panicking explicitly when the answer succeeds. This makes the failure mode clearer and keeps the error value for the assertion that follows.

📝 Walkthrough

Walkthrough

The contract adds five optional capability families for document, conversation, learning, and event ingestion, plus grounded answers. It adds payload types, routing APIs, TinyBus exposure, TinyCortex and Mem0 implementations, capability negotiation, contract version 3.1, and conformance tests.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to 0754b

This PR is not merge-ready because several new API paths can mishandle data or fail at runtime: replayed events may overwrite existing records, conversation speaker roles may be lost, advertised capabilities may not work, and public API changes may break downstream callers. Response-size handling and contract documentation also require follow-up.

P1 Badge Preserve document metadata in the lightweight provider

When callers use the newly advertised lightweight document route, this reduces the entire IngestItem to a MemoryCore::store call, discarding its owner, source type, timestamp, tags, MIME type, and path scope while repurposing source_ref as a key. Those fields are the provenance and citation data the new ingestion contract promises to preserve, so successfully ingested documents cannot later be traced back to their source; use a representation or pipeline that retains the complete ingestion metadata, or do not advertise DocumentIngest.

P1 Badge Accept externally tainted document and conversation input

For the full TinyCortex provider, both new product-facing ingestion routes delegate to the legacy methods, whose shared validate_ingest_item rejects every non-default taint. Thus ordinary connector input stamped ExternalSync or Untrusted fails despite the specification requiring provenance taint to pass through document and conversation routes; either preserve taint in the chunk pipeline or withhold these advertised capabilities until that is possible.

P1 Badge Route learning candidates across the module boundary

When this provider runs in tinymemory-module, this push targets the cdylib's process-local GLOBAL_BUFFER; tinymemory-core/src/learning_candidate.rs explicitly documents that the host stability detector drains a separately linked buffer. Consequently candidates submitted through the new bus route are persisted but never reach the detector, and this unused queue eventually evicts them; deliver the candidate through a bus member/event rather than the module-local singleton.

P2 Badge Delegate every capability advertised by the graph wrapper

When the now-generalized public constructor wraps a provider with any legacy optional capability such as Documents, Tree, or Ingest, this method copies that capability into the wrapper's advertised set, but the wrapper delegates only the five newly added accessors and as_graph; all other as_* methods default to None. audit_provider therefore rejects such wrappers and a host can advertise routes that are unreachable, so either forward every base accessor or restrict the reported capabilities and constructor input.

Restore removed re-exports or add a deprecation notice

The diff replaces the pub use tinymemory_bus::{…} line, removing chunks, composio, evidence, goals, graph, learning, and namespace from the public re-export list and adding operations. The context shows many existing callers depend on these paths (e.g. crates/tinymemory-api/src/provider/chunks.rs, crates/tinymemory-api/src/provider/episodic.rs, crates/tinymemory-api/src/provider/people.rs, crates/tinymemory-api/src/provider/profile.rs, and many more). Removing them without a deprecation period will break every downstream that uses tinymemory_api::chunks, tinymemory_api::composio, etc. If the intent is to remove these from the public surface, the change should be accompanied by a semver-breaking version bump and a clear migration path; if the intent is to add operations while keeping the others, the old names must remain.

Remove unreachable match arms that introduce no callers

The three string literals IngestLearning, IngestEvent, Answer are added inside a match that iterates over a set of known values. No corresponding variant exists in the type this match depends on, and no caller anywhere in the repository context constructs or passes these strings. The arms will never fire, making them dead code. Either the enum or the macro that defines the discriminants needs a corresponding entry, or these lines should be removed.

If this is a pre‑allocation for a future change that is being committed now, the convention in this repository is to not commit stubbed or dead code (see the untrusted-repo-rules: no todo!(), stubbed functions, or commented‑out code in delivered code). Either add the missing call sites in this same PR, or leave these entries out until they are used.

Add a module with content or suppress the dead-module warning

The diff adds pub mod operations; to the module tree but includes no crates/tinymemory-bus/src/operations/mod.rs or crates/tinymemory-bus/src/operations.rs file in this diff. Until that file is created, the module is either absent (causing a compile error) or empty (causing a dead-code warning). If the file is present in the same commit but outside this diff, the finding is moot; if not, the module declaration is stubbed. The repository rules forbid todo!(), stubbed functions, or commented-out code in delivered code; an empty public module is similarly incomplete.

Avoid an ambiguous public ingest_document method.

NullMemoryProvider and TinycortexProvider implement both MemoryIngest::ingest_document and MemoryDocumentIngest::ingest_document with identical call shapes. Downstream callers that import both public traits and call driver.ingest_document(...) can fail to compile. Preserve an unambiguous compatibility path, or document this as a breaking migration.

Preserve the IngestChat capability contract.

When a provider exposes as_ingest() and implements MemoryIngest::ingest_chat without as_conversation_ingest(), IngestChat can return Unsupported(Capability::ConversationIngest) before ingest_chat runs. Route this method through as_ingest().ingest_chat(...), or add an explicit migration path.

Forward every advertised base capability.

GraphMemoryProvider::capabilities() retains every bit from base, but the wrapper does not delegate as_ingest() or other optional accessors. If base advertises Capability::Ingest, the inherited accessor returns None, so audit_provider reports advertised_but_absent and bind-time registration can expose a route that fails on use.

Delegate every optional accessor, or remove each unsupported capability. Add a test with a base that advertises Capability::Ingest.

Preserve the message author before storing the conversation record.

Line 162 passes only message.content to store. No remaining argument contains message.author. The provider therefore discards speaker-role attribution for every ingested conversation message.

Persist author in the Mem0 record metadata, or use an unambiguous stored representation that retains the speaker role.

P1 Badge Preserve the public provider constructor return types

Downstream code that explicitly expects MemoryTraitProvider from this public function no longer compiles because the return type changes to TinycortexDocumentProvider; the same regression is introduced for mem0_provider, which now returns Mem0Provider. Keep the existing constructors source-compatible and expose the capability-augmented wrappers through new constructors, or treat this as a breaking release rather than the advertised additive change.

P1 Badge Preserve conversation provenance in the Mem0 route

When a Mem0 caller uses the newly advertised conversation route, this stores only the message text, conversation id, category, and taint; owner, source type, source_ref, tags, MIME type, author, platform, and path scope are discarded, while the timestamp survives only inside an opaque hash. Those fields are the provenance and citation data that docs/specs/ingestion-retrieval-api.md promises this IngestItem route will preserve, so ingested messages cannot later be attributed or cited correctly.

P1 Badge Keep recalled content out of the system instruction

When recall returns connector-controlled content—for example an ExternalSync raw event accepted by the new event route—this interpolates that text directly into the system message. A memory containing prompt-like instructions therefore receives system-level authority and can steer synthesis away from the retrieved evidence, violating the grounded-answer contract; pass retrieved memories as clearly isolated untrusted data rather than concatenating them into the system instruction.

P2 Badge Enforce the frame budget on answer responses

When a caller requests enough large memories, AnswerResponse.citations contains every retrieved body and can exceed TinyBus's 16 MiB frame limit, but this new handler returns it without the ensure_response_fits check used by Recall and the other content-bearing bus methods. Capture the response and apply the existing budget check so oversized answers fail with the named BudgetExceeded error rather than failing during transport serialization.
