P0 fixes:
- Replace unbounded daemon threads with ThreadPoolExecutor(max_workers=2)
  for embedding writes; atexit + close() ensure graceful shutdown so
  in-flight embeddings are not lost on process exit
- Restore apprise>=1.9.0 and feedgen>=1.0.0 removed in epic branch,
  which would have broken Epic #179 push/RSS features on merge

P1 fixes:
- _escape_fts: replace double-quote-only escaping with a whitelist regex
  [A-Za-z0-9_+-] so FTS5 operators (*, NEAR, NOT, ^) cannot alter query
  semantics; empty queries now short-circuit to []
- _hybrid_merge: skip items with None/invalid id instead of defaulting
  to id=0, preventing silent score collisions across unrelated records
- ReproExperienceStore: add application-level dedup check + UNIQUE
  constraint (paper_id, pattern_type, content) + IntegrityError fallback
  to prevent duplicate experiences from accumulating across retries

Migration:
- 0022_repro_experience_dedup: adds uq_repro_exp_paper_type_content
  unique constraint to existing repro_code_experience table

Tests: 47 unit tests pass (+3 new tests covering the fixes above)
…o pipeline

Add user-scoped isolation for repro_code_experience and enforce dedup semantics with migration 0022_repro_experience_dedup.

Inject ReproExperienceStore through ReproAgent/Orchestrator/CodingAgent/GenerationNode and propagate user_id/pack_id in generation, verification, and debugging persistence paths.

Update /api/gen-code to accept user_id and extend unit tests for user isolation and persistence behavior.
Add decay-aware scoring that combines relevance (confidence), recency
(exponential decay with 90-day half-life), and usage frequency to
re-rank search results. New memories default to expires_at = created_at
+ 365 days. search_memories() now auto-touches usage on hits.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add search_memories_batch() that queries multiple scope_ids in a single
SQL call, eliminating the N+1 loop in build_context_pack(). Engine now
uses this batch method for cross-track memory retrieval.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Refactor build_context_pack() into 4 layer methods:
- Layer 0: user profile (cached with 5-min TTL, ~200 tokens)
- Layer 1: track context — tasks/milestones (~500 tokens)
- Layer 2: query-relevant + cross-track memories (~1000 tokens)
- Layer 3: paper-scoped memories (on-demand)

Return value adds context_layers metadata while remaining fully
backward-compatible.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Use standard ln(2)/halfLifeDays lambda formula (matches OpenClaw
  temporal-decay.ts:toDecayLambda)
- Default half-life lowered to 30 days (was 90, now matches OpenClaw)
- Evergreen memories (global scope, preference kind) are immune to
  recency decay (inspired by OpenClaw isEvergreenMemoryPath)
- Add _to_decay_lambda() and _is_evergreen_memory() helpers
- Expand tests for lambda math, half-life precision, and evergreen logic

Memory vectors dance in FTS5 twilight,
Papers distill to blueprints, roadmaps unfold,
Context flows layered, a story retold,
Benchmarks and ROI paint metrics in gold!

Summary of Changes

Hello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the project's memory and code reproduction capabilities by integrating a comprehensive benchmarking suite, introducing advanced search and context management features, and enabling persistence of code generation experiences. These changes aim to improve the quality, reliability, and efficiency of the AI-powered research workflow, making the system more robust and intelligent in handling complex tasks.

Highlights

  • MemoryBench Evaluation Section Added: A new 'MemoryBench Evaluation' section has been added to the root README, detailing quantitative results for Retrieval (Recall/MRR/nDCG), Scope Isolation, Context Extraction, and Injection Robustness metrics, including a LoCoMo question-type breakdown table and one-command run instructions.
  • Comprehensive MemoryBench Suite: The pull request introduces a full MemoryBench suite covering retrieval quality, context extraction quality, scope isolation, injection robustness, latency/performance baselines, and ROI measurement for seeded reproduction memory, with dedicated documentation and fixtures.
  • Database Migrations for Enhanced Memory: New Alembic migrations have been added to support SQLite FTS5 full-text indexing, an embedding column for vector search with sqlite-vec, and a repro_code_experience table for persisting code generation experiences.
  • Advanced Memory Search Capabilities: The SqlAlchemyMemoryStore now supports hybrid search combining FTS5 and sqlite-vec (if available), decay-aware ranking, and Maximal Marginal Relevance (MMR) reranking for improved retrieval relevance and diversity.
  • Context Engine Enhancements: The ContextEngine has been updated with layered context loading, a token budget guard to manage context window size, and configurable memory search parameters, along with a hash-based embedding fallback provider.
  • Code Generation Experience Persistence: The ReproExperienceStore is introduced to persist successful code generation patterns, verified structures, and failure reasons, allowing CodeMemory to pre-load prior experiences for future runs and improve agent performance.
  • Robust LLM Integration and Error Handling: The OpenAIProvider now includes transient retry logic and a system message fallback mechanism, while frontend error handling has been improved to provide more user-friendly messages for upstream API issues.
  • Verification Runtime Management: A new verification_runtime module is added to manage Python virtual environments for code verification, including caching and normalized dependency installation, ensuring consistent and isolated execution environments.

Pull request overview

This PR significantly expands PaperBot’s offline evaluation/benchmarking tooling (MemoryBench + retrieval/context benchmarks) and adds supporting runtime, persistence, and UI error-handling changes across the repro + memory stack, along with extensive documentation updates.

Changes:

  • Adds offline benchmark suites (retrieval, context engine, injection robustness, memory performance, memory effectiveness, ROI) with fixtures, scripts, and CI smoke gates.
  • Introduces repro experience persistence (DB model + store + CodeMemory integration), verification runtime preparation, and P2C context-bridge enrichment.
  • Improves frontend error reporting by mapping upstream backend failures to friendlier UI messages.

This assertion is effectively a no-op because ... or True always evaluates to True, so it won’t catch cross-user leakage regressions. It should be removed or replaced with a strict check (the following assertion already covers the intended behavior).

The README’s primary heading was changed from the project name to a slogan. This makes the repo harder to identify/search and conflicts with the repository name/badges. Consider keeping the H1 as “PaperBot” and moving the slogan to a subtitle/tagline instead.

Code Review

This is a substantial and high-quality pull request that introduces a comprehensive benchmarking suite (MemoryBench) and significantly enhances the memory and code generation systems. The changes include new features like vector search, memory decay, and persistent code experiences, along with major improvements to robustness and error handling. The code is well-structured and the new documentation is thorough. I have a few suggestions for improving readability and future configurability.

Note: Security Review did not run due to the size of the PR.

The method of concatenating all API key variables to check if at least one is set is functional but can be difficult to read and debug. For better clarity and maintainability, I suggest checking each variable individually. This makes the condition's intent more explicit.

The new project name 'Oh, God! My idea comes true.' is unconventional and may not convey a professional image for the project. While this might be a deliberate creative choice, consider reverting to 'PaperBot' or choosing another name that is more descriptive of the project's purpose to aid in its branding and adoption.

The weights for vector search and BM25 search in the hybrid merge are hardcoded. While vec_weight=0.6 and bm25_weight=0.4 are reasonable defaults, making these configurable (e.g., through SqlAlchemyMemoryStore's configuration) would provide more flexibility for tuning retrieval performance in the future.
