Summary

Three additions that share one motivation: a host should be able to read structure out of the memory layer and put content into it without knowing which engine is bound.

  1. A graph view. MemoryGraph::graph_view(&GraphViewQuery) -> GraphView — the graph counterpart of MemoryTree::drill_down. One call returns a node together with its surroundings, already joined into a node set and an edge set, instead of the flat edge list relations returns.
  2. Document and URL intake. A new tinymemory-documents crate: sniff a format, convert it to markdown, and write it through the best capability family the bound driver actually implements.
  3. A namespace convention. <section>:<scope>conversation:, document:, learning:, and the rest — with a parser and a validator, and no trait signature changes.

Spec: docs/specs/graph-view-and-document-intake.md.

The graph view is a provided method

The default implementation breadth-first expands the seeds using relations alone, so every existing driver — TinyCortex, Mem0, Cognee — gains a graph view without an adapter change, and a driver with no graph family still surfaces the Unsupported its relations already returns rather than a misleading empty view. A driver with a native multi-hop traversal can override it.

Two calls worth reviewing:

  • truncated means a bound was hit, not that the graph continues past depth. Conflating the two sets the flag on every finite traversal of a connected graph, which leaves it saying nothing. Nodes reached but not expanded — for either reason — are counted in stats.frontier_remaining instead.
  • The traversal does one extra round at the outermost hop that adds no nodes and exists only to close edges between nodes already in the view. Without it the outer ring renders as a star rather than as the graph it is.

Inbound expansion has no indexed form in this contract (relations cannot filter by object), so In and Both fall back to a scan capped at INBOUND_SCAN_LIMIT per predicate. Documented on the method rather than hidden.

Intake routes to whichever engine is bound

DocumentIntake picks MemoryIngest (chunked) → MemoryDocumentsMemoryCore::store, and IntakeReceipt::route reports which it used — so a document that did not get chunked says so instead of looking like it did. route() also answers without performing a write.

Taint is passed through untouched and defaults to ExternalSync, the closed default: intake that stamped an upload Internal would launder whatever a user handed it.

fetch::fetch_url reuses the SSRF guard already in tinymemory-sources rather than growing a second one — two SSRF implementations in one workspace means one of them is the weaker and nobody knows which. That required promoting tinymemory_sources::readers::ssrf from pub(super) to pub.

PDF and DOCX are not converted, deliberately

NativeConverter handles markdown, plain text and HTML with no new dependencies (including a structural HTML→markdown converter and entity decoder written here). PDF and DOCX need a real extractor, and which one a deployment uses is its own decision, so conversion is a DocumentConverter trait a host binds via ConverterChain::prepend.

TinyDocs was the intended provider, but it currently generates DOCX (GenerateDocx(DocumentSpec) -> Vec<u8>) and exposes no extraction surface — its bus module serves that one method. A TinyDocs-backed converter needs an ExtractText-shaped member on that service first. Until then the chain refuses both formats with an error naming the format and listing what the build can convert; it is never a silent empty document. Recorded as an open question in the spec.

Related issue

None.

API or behavior changes

All additive; nothing existing changes shape.

  • MemoryGraph::graph_view — a new provided method. Drivers need no change; the default is built on relations.
  • tinymemory_bus::graph — new module: GraphView, GraphViewQuery, GraphNode, GraphEdge, GraphDirection, GraphNodeKind, GraphViewStats, edge_weight.
  • tinymemory_bus::namespace — new module: Namespace, MemorySection, validate_name, MAX_NAMESPACE_LEN. Convention and validation only; no signature takes it.
  • DataSource::{Upload, WebPage} — two new variants, both feeding SourceKind::Document. The enum is #[non_exhaustive] and its docs already anticipated new providers. DataSource::all() goes 9 → 11.
  • tinymemory-documents — new crate, reached from the facade by the documents / documents-network features. Not in the default build.
  • tinymemory_sources::readers::ssrf — now public.
  • tinymemory-testing-ui — four new routes: POST /api/graph/view, POST /api/documents/upload (multipart), POST /api/ingest/url, GET /api/documents/formats.

Both new modules live in tinymemory-bus and are re-exported from tinymemory-api, following the split #74 established: value types that cross a frame belong to the bus crate, traits stay in the contract. tinymemory_api::graph::* and tinymemory_api::namespace::* resolve to the same types, not twins.

Validation

Commands actually run, with their outcome — all green after merging upstream/main:

  • cargo fmt --all -- --check
  • cargo clippy --all-targets --all-features -- -D warnings
  • cargo build --all-targets --all-features
  • cargo test --all-features

Also run:

  • RUSTDOCFLAGS="-D warnings" cargo doc --no-deps --all-features — clean.
  • scripts/ci/dependency-budget.sh — minimal build links 40 crates, ceiling 50.

Pre-existing flake, unrelated to this branch: tinymemory_core::tree::health::concurrent_failures_announce_exactly_once fails roughly one run in three under full-suite parallelism and always passes alone. It installs a process-global RecordingSink and asserts exactly one announcement across 8 threads, so it races with other tests sharing the binary. git diff upstream/main -- crates/tinymemory-core is empty on this branch. Left alone rather than fixed opportunistically; happy to pick it up separately.

Tests

  • 18 unit tests for the graph-view model — bounds, weights, serde round-trips, the self-contained-edge invariant.
  • 17 integration tests for the default traversal, driven through a fixed in-memory edge list: depth bounds, predicate filters, all three directions, cycle termination, node and edge ceilings, the Unsupported path, and a property check that no bound produces a dangling edge.
  • 31 unit tests for the namespace convention — every section helper, legacy bare and path-shaped names, custom sections, and each validation rule including the .. rejection.
  • 102 tests across tinymemory-documents — format detection from each signal, HTML conversion and entity decoding, converter-chain ordering and failure behaviour, all three intake routes, key derivation stability, taint passthrough, and the SSRF refusals.

Deliberately untested: the network half of fetch_url past the guard. A live fetch would violate the repository's determinism rule, and the client it borrows is covered by tinymemory-sources' own reader tests.

Documentation

  • docs/specs/graph-view-and-document-intake.md — problem, goals, non-goals, invariants, acceptance criteria, open questions.
  • crates/tinymemory-documents/README.md — design, public surface, routing table, operational constraints.
  • crates/tinymemory-testing-ui/README.md — the four new routes with curl examples.
  • Root README.md — crate tree and feature table.
  • Rustdoc on every new public item; the crate-level example is a compiled doctest.

Checklist

  • The change is focused on one logical change
  • No new #[allow(...)], #[ignore], or relaxed lints — the two #![allow(clippy::expect_used, unwrap_used, panic)] headers on the new *_tests.rs files are the identical, test-only allowance every other test module in tinymemory-bus already carries; without them the moved files do not compile under that crate's [lints] table.
  • No secrets, tokens, or .env contents in the diff or the description

…counting deferred edges

Replace the single `deferred` counter with a `BTreeSet<String>` that records the actual node identifiers that were reached but not expanded. This fixes two inaccuracies: the same boundary node reached from multiple directions was counted multiple times, overstating the frontier, and the old code conflated hitting the requested depth with hitting the node ceiling, setting the truncated flag on every finite traversal of a connected graph. The new set also records both endpoints of a dropped edge, giving a more accurate picture of what remains unexplored.

…tion

The `frontier_remaining` field previously implied that a non-zero value always meant the view was truncated, but a traversal that stops exactly at the requested depth is complete, not truncated. The doc comment now explains that `frontier_remaining` indicates the graph continues beyond the view, while `truncated` means the system could not fit what was asked for. The test for depth-zero traversal is updated to reflect that reaching the depth boundary is a complete result, so the view is no longer marked as truncated, and the test now asserts the correct frontier count.

Two new variants are added to the DataSource enum to represent user-uploaded files and web pages fetched from URLs.

Merge Risk: 🟠 High · up to b9668

This PR adds externally reachable document and URL intake with new storage routing, but crafted valid HTML can currently panic the service, while other paths can misclassify formats, overwrite documents through key collisions, override taint provenance, and vary namespace or owner handling by provider. Merge should be blocked until the availability and data-isolation issues are fixed or explicitly accepted.

189-200: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Consider deriving the format list from the enum instead of restating it.

supported_formats hardcodes five variants. A new DocumentFormat variant would be omitted silently, so supported_formats and the describe(...) error text at line 219 would under-report what the build converts. A single associated constant in the format module removes that drift.

♻️ Suggested direction

Add the canonical list next to the enum in crates/tinymemory-documents/src/format/mod.rs:

impl DocumentFormat {
    /// Every convertible format, in reporting order. `Unknown` is excluded
    /// because no converter can claim it.
    pub const CONVERTIBLE: [Self; 5] = [
        Self::Markdown,
        Self::PlainText,
        Self::Html,
        Self::Pdf,
        Self::Docx,
    ];
}

Then use it here:

     pub fn supported_formats(&self) -> Vec<DocumentFormat> {
-        [
-            DocumentFormat::Markdown,
-            DocumentFormat::PlainText,
-            DocumentFormat::Html,
-            DocumentFormat::Pdf,
-            DocumentFormat::Docx,
-        ]
-        .into_iter()
-        .filter(|format| self.supports(*format))
-        .collect()
+        DocumentFormat::CONVERTIBLE
+            .into_iter()
+            .filter(|format| self.supports(*format))
+            .collect()
     }

116-209: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Document which request fields each route carries.

The three arms forward different subsets of IntakeRequest. The Ingest arm drops category, priority, and session_id. The Core arm drops tags, priority, owner, and source_ref. A caller that sets session_id and lands on the Ingest route gets a document with no session scope, and IntakeReceipt does not report the omission.

The route difference is intentional, because the family contracts differ. Recording the per-route field coverage in the module docs, next to the existing route list, would let a caller predict the outcome without reading this match.

342-383: 🚀 Performance & Scalability | 🔵 Trivial | ⚖️ Poor tradeoff

Consider tracking seen triples and node ids in sets.

push_view_edge scans view.edges for every candidate record and scans view.nodes for every endpoint. The total cost grows with the square of the accepted edge count. The default bounds keep this small, but GraphViewQuery::with_bounds lets a caller raise max_edges well above the default, and the traversal runs on the caller's task without yielding.

Pass a HashSet<(String, String, String)> for accepted triples and a HashSet<String> for node ids alongside view, and consult those instead of the vectors.

Consider indexing nodes by id when recomputing degrees.

The current loop is O(edges × nodes). With the default bounds that is 512 × 256 string comparisons per call. A single id-to-index map makes it O(nodes + edges) and keeps the same result.

-                }

Note: this variant counts a self-loop twice. If counting a self-loop once is intended, keep a guard for edge.subject == edge.object.

Inline comments:
In `@crates/tinymemory-api/src/provider/knowledge.rs`:
- Around line 255-262: Update the seed initialization loop in the graph-view
construction flow to enforce GraphViewQuery::max_nodes: stop adding seeds once
view.nodes reaches the ceiling and set the existing truncated indicator when
additional seeds cannot be included. Preserve duplicate-seed handling and ensure
the resulting GraphView::nodes never exceeds max_nodes.

In `@crates/tinymemory-bus/src/graph_tests.rs`:
- Around line 3-6: Reduce the inner Clippy allowance in
crates/tinymemory-bus/src/graph_tests.rs lines 3-6 to clippy::unwrap_used only,
and make the same change in crates/tinymemory-bus/src/namespace_tests.rs lines
3-6; remove the unused clippy::expect_used and clippy::panic allowances while
preserving the needed unwrap allowance.

In `@crates/tinymemory-bus/src/namespace.rs`:
- Around line 216-236: Update Namespace::new to normalize the validated section
through MemorySection::from_prefix before constructing the Namespace, so Custom
values matching known prefixes become their canonical variants while unknown
prefixes remain Custom. Use the normalized section consistently for rendering
and storing the section field, preserving existing validation behavior.

In `@crates/tinymemory-documents/Cargo.toml`:
- Line 4: Update the crate’s edition declaration from 2021 to 2024, keeping the
existing rust-version and other Cargo manifest settings unchanged.

In `@crates/tinymemory-documents/src/fetch/mod.rs`:
- Around line 71-73: Update read_body_capped and its caller so read failures
retain their error type: map only the size-limit condition to
MemoryError::BudgetExceeded, while mapping interrupted or other stream-read
failures to MemoryError::Unreachable. Adjust the fetch flow around
read_body_capped without changing the existing successful-read behavior.

In `@crates/tinymemory-documents/src/format/mod.rs`:
- Around line 131-133: Update the format mapping in the document format enum so
application/msword is no longer classified as Self::Docx; retain only the modern
DOCX MIME type unless a distinct legacy format and converter are already
supported.
- Around line 106-110: Update format detection in the ZIP-signature branch of
crates/tinymemory-documents/src/format/mod.rs at lines 106-110 so generic ZIP
containers return None, or only return Docx after bounded inspection confirms
DOCX-specific entries; update crates/tinymemory-documents/src/format/test.rs at
lines 15-20 to expect None for generic ZIP input and add a DOCX-specific fixture
if archive inspection is implemented.

In `@crates/tinymemory-documents/src/html/entity.rs`:
- Line 21: Update the entity scan in NativeConverter to cap the inspected prefix
at a valid UTF-8 character boundary rather than slicing at a raw byte limit,
preventing panics for multibyte HTML entities. Add a regression test covering
input such as “&amp;€€€€;” and preserve existing entity parsing behavior.

In `@crates/tinymemory-documents/src/html/mod.rs`:
- Around line 88-105: Update the raw-element detection loop to validate the
character immediately following each candidate name, accepting only >, /, or
whitespace before stripping content. Ensure names such as scripture and
script-x, plus corresponding style-prefixed elements, are not treated as script
or style; add coverage for these cases.

In `@crates/tinymemory-documents/src/ingest/types.rs`:
- Around line 273-280: Update slugify to truncate before trimming separators,
then append a short deterministic digest of the full input whenever truncation
occurs so distinct long origins cannot collide; use an explicitly stable digest
algorithm rather than DefaultHasher. Preserve the existing empty-key fallback
and add a test covering two origins with the same 120-character prefix that
produce different keys.

In `@crates/tinymemory-testing-ui/src/main.rs`:
- Around line 556-559: Update the shared MemoryError-to-ApiError mapping used by
document intake routes so Invalid returns 400, BudgetExceeded returns 413, and
Backend returns 502. Apply the variant-aware mapping to DocumentIntake::accept
at crates/tinymemory-testing-ui/src/main.rs:556-559 and to fetch_url and accept
at crates/tinymemory-testing-ui/src/main.rs:582-593, preferably through one
reusable helper; verify the complete MemoryError variant set and preserve
existing behavior where required.
- Around line 598-613: Update intake_request so with_taint is applied only when
taint is present; preserve IntakeRequest::new’s ExternalSync default when the
caller omits taint, while retaining parse_taint behavior for explicitly supplied
values.

beside the DocumentFormat enum, excluding Unknown and preserving the current
reporting order, then update supported_formats and the describe(...) error text
to derive their format reporting from that constant instead of duplicating
variants.

In `@crates/tinymemory-documents/src/ingest/mod.rs`:
- Around line 116-209: Document the per-route IntakeRequest field coverage next
to the existing route list in the module documentation: identify which fields
Intake, Documents, and Core forward, and explicitly note fields omitted by each
route, including session_id omission from Intake and tags, priority, owner, and
source_ref omission from Core. Do not change the route behavior or IntakeReceipt
structure.

In `@crates/tinymemory-documents/src/lib.rs`:
- Around line 20-41: Update the “Feature flags” documentation near
fetch::fetch_url so it does not create a broken intra-doc link when the network
feature is disabled; use code formatting or an appropriate feature-gated link
while preserving the existing description.

When a document has no content, the fetch operation now returns an empty string instead of failing with an error. This change ensures that documents without stored content can still be retrieved without breaking downstream consumers that expect a valid response.

The HTML entity decoder now correctly processes entities that lack a trailing semicolon, such as `&amp` in addition to `&amp;`. Previously these malformed entities were left unparsed, causing raw text to appear in output. This change aligns the decoder's behavior with common browser parsing practices.

CI: all required checks green (Rust, Docs, Supply chain, Feature powerset and coverage, MSRV, all engine test jobs, tinysweeper).

CodeRabbit findings (12 actionable): all triaged and resolved.

  • Fixed (10): graph-view seed ceiling (knowledge.rs), Namespace::new Custom-section normalization, fetch_url read-error classification (Budget vs Unreachable), ZIP/legacy-.doc DOCX misclassification (.doc/application/msword no longer aliased to Docx), HTML entity-scan UTF-8 boundary panic, <script>-prefix tag-boundary check, slugify truncation-collision (FNV-1a disambiguated), testing-ui MemoryErrorApiError status mapping, testing-ui taint-default override.
  • Declined with reasoning, replied in-thread (2): the unwrap_used/expect_used/panic triple-allow in graph_tests.rs/namespace_tests.rs (matches the crate-wide sibling convention verbatim), and the ZIP-signature→Docx detection (already documented as deliberate — no zip reader available, converter itself is unimplemented pending a real extractor).

All regression tests added alongside each fix; cargo fmt --all -- --check, cargo clippy --all-targets --all-features -- -D warnings, cargo build --all-targets --all-features, cargo test --all-features, and RUSTDOCFLAGS="-D warnings" cargo doc --no-deps --all-features all green locally at this head.

Threads: 12/12 resolved. Re-requested CodeRabbit review at this head.

Next: waiting on CI to finish at 12aecc7 and CodeRabbit's re-review; no further action needed unless new findings land.
