Five contract doors for the openhuman engine shed - #122
YellowSnnowmann merged 3 commits into
Conversation
openhuman#5560 removes tinycortex and tinymemory-core from the host build, reaching the engine only through this contract over the TinyBus module. Five host surfaces had no door; this adds them, all as defaulted trait methods so every other driver keeps compiling and an older pinned artifact answers Unsupported instead of failing to load. MemoryTree: - summarise — the archivist recap fold. Owned wire twins of SummaryInput / SummaryContext / SummaryOutput (the usage-carrying tinymemory-core one); tree_kind travels as an open string per the retrieval-hit precedent, noting the hazard is symmetric because here it rides a request. - root_summaries_with_caps — the system-prompt tree summaries, tuple named as RootSummary. Infallible engine-side; only the default body errors. MemoryChunks: - chunk_score — the score-row read behind the dashboard's score breakdown, with ChunkScore/ChunkScoreSignals carried faithfully (including the two fields that always read back empty, documented) and DEFAULT_DROP_THRESHOLD published so the host stops hardcoding 0.3. - source_ingest_status — the per-configured-source sync counters. This is NOT source_totals: chunks_pending spans three tables no chunk member exposes, a zero-chunk source must still get a row, and the grouping key is the registry entry, not the chunk ingest key — the host supplies the prefix, the engine counts. The three-table pending predicate now lives once, in core, shared by the old path and the new door; the new door's LIKE prefix is escaped (the old path's unescaped `_` over-match is preserved there, proven by test, so nothing shipped changes). MemoryMaintenance: - degraded_state — the cheap atomics read behind pipeline_status, separate from diagnose because the hot path must not run the doctor. diagnose itself needed nothing: the provider already implements it; its degraded mapping is now shared with the new member so the two cannot disagree. METHODS grows 126 -> 131, appended in wire order; the module serves all five and its sequence/manifest assertions pin them. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Three review findings from tinyhumansai#122, one of which was also the red CI lane: - module_e2e's EXPECTED_METHODS — the test's own hardcoded manifest copy — gained Summarise/RootSummaries but not the other three new members, so the_manifest_declares_every_method_the_module_serves failed on exactly ["ChunkScore", "DegradedState", "SourceIngestStatus"]. All five are now listed. This list is deliberately a second copy (drift witness), which is why it fails instead of following names.rs automatically. - chunks_tests.rs allowed clippy::unwrap_used and clippy::panic while using only expect; the allowance now matches what the file actually trips. - source_status/status_list document their failure contracts: per-source store failures degrade that row to zeroed counts rather than failing the batch (verified against the loop, not asserted from memory), and a prefix matching nothing is an answer, not an error.

Validate LIKE patterns passed to SQL query
ingest_counts_for_patterns forwards each caller-supplied pattern string directly into the SQL query WHERE c.source_id LIKE ?1 ESCAPE '\'. While the current callers are internal and control their own prefixes, this public function's contract does not prevent future callers from passing arbitrary or user-controlled data. An attacker who can influence the pattern could inject SQL by embedding a single quote (') or by exploiting the fact that the LIKE wildcard characters (%, _) are not escaped in the supplied pattern — the ESCAPE '\' only affects \ in the pattern itself, not % or _ from external callers. Mitigate by either: (a) making the function private or pub(crate), (b) validating that the pattern consists only of the caller's own source-id prefix (alphanumerics, colons, hyphens, underscores), or (c) documenting that patterns must be sanitised before calling.

Addressed in 1bd984d. One correction first: the injection half of this does not hold — the pattern is a bound parameter (?1), so a quote in it can never terminate or extend the SQL. The kernel that does hold is over-match: a pub fn whose argument is a LIKE pattern invites a future caller to pass an unescaped id, and %/_ then match more source ids than intended, silently. Fix: the sanctioned escape (like_prefix_pattern) moved from the tinycortex driver into core directly beside the ESCAPE '\' query it pairs with (the driver's copy is now a name for it), and the pattern contract is documented on ingest_counts_for_patterns itself — bound therefore injection-free; escape-first therefore no over-match; the helper one line up. Option (b)'s charset validation would reject the escaped patterns the driver legitimately sends (they contain \), so proximity + contract is the mitigation that fits.

tinysweeper flagged ingest_counts_for_patterns for taking raw LIKE patterns. Half the finding does not hold — the pattern is a bound parameter, so it can never terminate or extend the SQL — but the kernel does: a pub function whose argument is a pattern invites a future caller to pass an unescaped id, and `%`/`_` then over-match silently. The sanctioned escape (like_prefix_pattern) moves from the tinycortex driver into core, directly beside the ESCAPE '\' query it pairs with, and the driver's copy becomes a name for it. The pattern contract is now documented on the function itself: bound therefore injection-free, over-match therefore escape-first, and the helper to do it one line up.

Validate LIKE patterns passed to SQL query
The pattern parameter is bound as a parameter (?1), so it cannot be used to alter the SQL statement structure. However, the LIKE pattern syntax itself gives a caller broad control over which rows match: an unescaped % or _ in the pattern can match rows the caller was not supposed to see. The like_prefix_pattern helper correctly escapes \, %, and _, so an input that goes through that helper is safe from over-match. The new ingest_counts_for_patterns function accepts arbitrary &[String] and passes them straight through without requiring the caller to have used like_prefix_pattern. While the doc comment says patterns should be derived from like_prefix_pattern, nothing enforces this contract at the type level. Consider taking Pattern newtype that can only be constructed via like_prefix_pattern, or rename the parameter to make clear it is a SQL pattern (not a plain id prefix).

Round two of the contract surface openhuman#5560 needs before the host can stop linking tinycortex and tinymemory-core. Round one (tinyhumansai#122, v1.13.5) left the tree_runtime operation set and flavour.rs as blocked residue; these are the doors that clear it. METHODS goes 131 -> 138. The six runtime members are the markdown time tree addressed node by node, which is what the host's tree_summarizer_* RPCs report verbatim: RuntimeBufferWrite buffer content, answering with the landing path RuntimeReadNode one node, or None RuntimeReadChildren a node's direct children RuntimeTreeStatus one namespace's shape and coverage RuntimeSummarize drain the buffer, answering with the hour node written RuntimeRebuild rebuild the tree from its hour leaves Append, DrillDown, Seal and Cascade are the same tree at a coarser grain, and each folds away a piece of the reply those RPCs carry — migrating onto them would have changed the host's wire format, and a door that changes what the host reports is not a door but a new surface. FlavourProfile collapses the whole compiled-root lookup the host ran against the engine directly behind one scope-shaped question. The contract goes to (4, 0). All seven land on Tree, a family a driver may already advertise, and version.rs is explicit that such an addition cannot be made minor-safe: negotiation is family-granular, not method-granular, so there is no way to advertise "Tree, but without the new methods" and an older driver still advertising Tree would be bound and then asked for a method it has never heard of. The major half refuses that bind up front instead of discovering it at the call. is_compatible compares the major half only, so this refuses the bind against every deployed v1.13.5 module and hosts must re-pin; the openhuman host re-pins in openhuman#5875. Round one did not bump, and neither did tinyhumansai#85/tinyhumansai#86/tinyhumansai#89/tinyhumansai#90 — version_tests.rs already calls that drift rather than precedent, and its history note now records tinyhumansai#122 alongside them. Every trait method is defaulted to unsupported(Tree), so a driver built against the older contract keeps compiling. The two provider-backed members resolve the summariser before the engine is asked anything: these are a person's explicit "run now", and a runner that could not have run must say so rather than answer None as if it had looked. Seal and Cascade keep their empty short-circuits; they are the scheduler's. The three members answering with tree nodes are checked against the response ceiling. A level's max_tokens bounds a node's summary and nothing else — the fold applies it to the body alone — while metadata carries a pending-fold receipt naming every buffer file the pass drained, so it grows with how much was buffered rather than with any budget. Without the check an oversized node fails during frame encoding; with it the caller gets BUDGET_EXCEEDED and a reason. The pre-existing tree members that skip the check are left alone. The module's seven service members are covered in pairs — the refusal a driver without the Tree family must give, and the answers the port carries back from one that has it. Without them the module's production-source coverage gate fell to 77.4%: the seven delegations are only reachable through the loader E2E, which is `#[ignore]`d and so invisible to llvm-cov, and v1.13.5 had just 0.33 points of headroom over the 80% floor. The tinymemory-bus README's member count was still the hardcoded 120 that round one replaced with METHODS.len() in the crate docs but missed here.
