What gets written? | Agent notes distilled from experiences, with content and metadata. | Topic documents assembled from buffered observations and summaries. | Typed memory objects and graph relations. | Reusable task plans, not only answer text. | Historical software-engineering trajectories and patches are the continual-learning material; no production write policy. | Repository context and historical artifacts selected for a task; benchmark framing, not a writer. | Persistent code-agent notes, summaries, and hindsight from trajectories. | Long-horizon repository changes and evolution traces; no dedicated memory writer. | Long-running task state and accumulated context; no dedicated memory schema. | Retrieved passages/chunks and their evaluation metadata. | +| 2. Who decides to write? | The agent constructs a note after an interaction and links it to existing notes. | A memory-writing process buffers and organizes content into topic documents. | A controller/agentic memory operation decides what enters the typed graph and checks conflicts. | The planner/cache policy decides when a plan is worth caching and reusing. | Not specified as a memory authority; the dataset records chronological task outcomes. | Not specified; it evaluates context selection and leakage rather than ingestion authority. | The coding agent writes useful notes and hindsight while skipping low-signal trajectories. | Not explicit; the environment supplies a long-horizon task sequence. | Not explicit; the task runner retains state needed for marathon execution. | Ingestion/indexing choices are system-dependent; the survey treats them as pipeline components. | +| 3. What is the retrieval unit? | An atomic note plus linked notes. | A topic document, with iterative expansion when a single topic is insufficient. | A typed graph node/subgraph and its relations. | A plan template or cached plan selected for a new task. | A prior task/patch/trajectory and its repository context. | A context item or set of repository artifacts selected for the current issue. | A relevant persistent note or hindsight record. | A repository change/task state across a long horizon. | A durable task state or historical context segment. | A chunk, document, passage, or retrieved context set. | +| 4. How are memories merged or maintained? | Notes evolve and acquire dynamic links as new interactions arrive. | Buffered writing, topic-document split/merge, and maintenance keep context bounded. | Graph updates, typed relations, and conflict detection support maintenance. | Cache reuse/adaptation is plan-level maintenance; invalidation is applicability-driven. | No memory merge algorithm; chronological task ordering prevents accidental future leakage. | No memory merge algorithm; context construction and ordering are evaluated. | Notes are updated with summaries/hindsight, and low-value traces can be skipped. | Evolution is represented by successive repository changes, not a note merge policy. | Long-horizon context must be carried/condensed, but a merge algorithm is not the central contribution. | Deduplication, chunking, fusion, and reranking are alternative retrieval pipeline operations. | +| 5. How are contradictions represented? | Related links/evolution can preserve changing notes, but explicit contradiction policy is not the central result. | Topic maintenance can consolidate information; explicit contradiction semantics are not the central result. | Explicit conflict detection and typed graph relations are first-class. | A plan's applicability can differ from a cached plan; explicit contradiction representation is limited. | Later patches can contradict earlier fixes chronologically; the benchmark warns against treating history as truth. | Conflicting or poisoned context is a retrieval/evaluation risk, not a prescribed graph model. | Hindsight can correct earlier paths, but a formal contradiction graph is not explicit. | Revisions and regressions are observable through repository history. | Reverted or superseded task state is a natural long-horizon hazard, not a formal memory relation. | Conflict, faithfulness, and citation/attribution errors are evaluation concerns; representation is system-specific. | +| 6. How is forgetting/deletion handled? | Not a central explicit mechanism; note evolution and retrieval selection control exposure. | Bounded topic documents and maintenance control context growth; hard deletion semantics are not central. | Explicit update/deletion operations are part of graph-memory maintenance. | Cache eviction/invalidation follows plan usefulness and applicability. | Dataset curation and chronological splits control exposure rather than delete provenance. | Split design and leakage controls remove context from a test view without destroying history. | Skipping low-signal trajectories prevents ingestion; full provenance is not necessarily erased. | Not explicit; repository history is retained as the environment evolves. | Not explicit; context compression/retention is operational rather than a deletion policy. | Forgetting is outside the core RAG pipeline; retention and privacy are deployment choices. | +| 7. How is confidence assigned? | Note usefulness is driven by learned links/evolution; a separate evidence-backed confidence class is not central. | Retrieval/writing quality is measured, but an explicit per-memory factual confidence field is not central. | Confidence is a first-class graph-memory signal alongside conflict handling. | Cache value/usefulness is measured by plan reuse and success, not necessarily factual confidence. | Patch/task success and chronology provide evidence; no general confidence field. | Retrieval labels and benchmark scores provide evidence; no persistent memory confidence field. | Verification and hindsight provide stronger evidence than raw trajectory similarity; a formal confidence taxonomy is not central. | Task success/evolution outcomes are evidence, not a confidence schema. | Long-horizon completion evidence is available, but formal memory confidence is not central. | Confidence/calibration and answer faithfulness are evaluation dimensions, not one required storage field. | +| 8. How are environment and versions handled? | Context and links carry task situation, but explicit structured dependency constraints are not central. | Topics and retrieved history carry context; structured repository/version compatibility is not central. | Typed relations can encode context, but explicit package/runtime version matching is not the main contribution. | Plan applicability is conditioned on the task/environment, making adaptation important. | Chronological repository/task history and continual shifts make version/time handling essential. | Temporal context and repository state are central to avoiding leakage and invalid reuse. | Repository state, tools, and trajectory context are retained in code-agent notes. | Repository versions and multi-change evolution are central to the task design. | Multi-hour/multi-version progression is central to the benchmark setting. | Metadata, query/document context, and provenance can support compatibility, but the survey does not prescribe a schema. | +| 9. Is retrieval iterative? | Linked-note expansion and memory evolution support more than one-hop retrieval. | Iterative retrieval and topic refinement are explicit design ideas. | Graph traversal and relation-aware retrieval can expand context. | Retrieve a plan, assess applicability, and adapt/replan when the cache is insufficient. | Agent loops may revisit repository context, but the benchmark is not an iterative-retrieval algorithm. | Context selection can be staged, but iterative retrieval is not the central benchmark claim. | The agent can retrieve notes, act, and add hindsight across a trajectory. | Long-horizon work naturally requires repeated context gathering, without a fixed retrieval controller. | Repeated context retrieval is required by the marathon setting, without a single prescribed algorithm. | Multi-stage, agentic, hybrid, and reranked retrieval are surveyed as possible pipeline designs. | +| 10. What is explainable or provenance-bearing? | Linked notes expose related context and note evolution. | Topic organization and retrieval paths expose why a topic document was used. | Typed graph edges, conflicts, and confidence provide explicit evidence paths. | The cached plan and its reuse outcome explain the cache decision. | Patch history, task chronology, and repository context provide provenance. | Ranked context items and temporal split construction provide evaluation provenance. | Notes/hindsight connect actions and outcomes across the coding trajectory. | Commits, diffs, tests, and repository history provide evidence. | Long-horizon task traces and checkpoints provide evidence of progress. | Retrieval rankings, citations/attribution, faithfulness, and calibration are the main explanation/evaluation surfaces. | + +## Concrete ClankerOverflow recommendation + +The benchmark turns the cross-paper pattern into a conservative memory contract: + +1. Write only verified, reusable fixes, adaptable plans, and useful hindsight. Keep raw trajectories temporary, and skip ingestion when there is no durable evidence or novelty. +2. Let an asynchronous ingestion agent propose candidates, but gate persistence with deterministic completeness and verification checks. Escalate unresolved or high-impact conflicts for human review. +3. Retrieve atomic solution cases or plan templates first. Expand only into evidence, related cases, and topic context when the first result is ambiguous or incomplete, with at most one refinement. +4. Preserve history with typed `related_to`, `adapts`, `supersedes`, `reverts`, and `conflicts_with` relations. Inactive memories leave active retrieval but remain auditable; privacy deletion is the hard-delete exception. +5. Compute confidence from captured evidence and constraints, not from similarity or votes. Keep usefulness votes separate from factual confidence. +6. Record repository identity, commit/range, dependency and runtime versions, toolchain, package manager, OS/architecture, files, commands, and error fingerprints as structured constraints. +7. Emit an explanation trace for every candidate decision: lexical rank, matched fingerprints, constraint checks, status, confidence, and relationship evidence. +8. Store reusable task plans as `memoryKind: plan`, and adapt them to the current environment rather than treating them as cached answers. + +## Current-state gap analysis + +The production solution table remains intentionally flat: problem, solution, tags, score, timestamps, and user identity are the durable fields. The v2 local retrieval path uses exact-first and tiered SQLite FTS5 keyword retrieval. The isolated `retrieval-memory/` benchmark keeps the richer safety labels as a pressure test without changing production storage. + +The benchmark's structured fixtures model the target richer contract without claiming that production already stores it. Its negative cases are designed to expose the risks that a similarity-only production change would need to address: stale/reverted fixes, wrong versions, same-error root causes, incompatible platforms, lexical distractors, and cases where abstention is the correct answer. diff --git a/clankeroverflow-mcp-workspace/retrieval-memory/retrieval.ts b/clankeroverflow-mcp-workspace/retrieval-memory/retrieval.ts new file mode 100644 index 0000000..8f0c5a8 --- /dev/null +++ b/clankeroverflow-mcp-workspace/retrieval-memory/retrieval.ts @@ -0,0 +1,256 @@ +import { mkdtempSync, rmSync } from "node:fs"; +import { tmpdir } from "node:os"; +import { join } from "node:path"; + +import type { SolutionResult } from "../../packages/cli/src/mcp/backend.js"; +import { LocalBackend } from "../../packages/cli/src/mcp/local-backend.js"; +import { benchmarkDataset, solutionDocumentText } from "./fixtures.js"; +import type { + BenchmarkDataset, + ConstraintCheck, + EnvironmentConstraints, + ExplanationTrace, + MethodQueryResult, + RequiredConstraints, + RetrievalCase, + RetrievalMethod, + SolutionFixture, +} from "./types.js"; + +export type RetrievalOptions = { methods: readonly RetrievalMethod[] }; + +export type RawMethodResult = { + method: RetrievalMethod; + ranking: string[]; + scores: Map; + traces: ExplanationTrace[]; +}; + +export type BenchmarkIndex = { + backend: LocalBackend; + directory: string; + solutions: readonly SolutionFixture[]; + fixtureIdByBackendId: ReadonlyMap; + close(): void; +}; + +function keywordSafeQuery(text: string) { + return (text.toLowerCase().match(/[\p{L}\p{N}_]+/gu) ??
