This commit ports the remaining Gen 1 proof-of-concept experiments from `forum/poc-g1` into `forum/poc-g2` while substituting naive mocks with real, production-ready mechanisms. Key advancements include: - `code_intelligence_poc.ts` and `cfg_poc.ts`: Swapped regex matching for actual Javascript AST traversal using `acorn`. - `static_analysis_poc.ts`: Replaced mock payloads with real `deno lint --json` output executed via `Deno.Command`. - `vector_db_poc.ts` and `multi_vec_poc.ts`: Replaced basic JS arrays with actual `jsr:@db/sqlite` instances utilizing User-Defined Functions (UDFs) to perform native vector cosine similarity queries in memory or on disk. - `protobuf_poc.ts`: Implemented robust protobuf serialization/deserialization via `protobufjs`. - Semantic/Governance PoCs (`constitution_poc.ts`, `ontology_poc.ts`, `state_machine_poc.ts`, `orphan_branch_poc.ts`, etc): Replaced string-mock I/O with absolute filesystem reads, real YAML parsing using `jsr:@std/yaml`, and isolated `Deno.Command` Git sandboxes. - Updated `forum/poc-g2/lab.ts` to orchestrate and execute all 19 experiments, proving 100% test pass rate with Gen 2 tooling.

* Proof of Concept: Multi-Vec Isolation (Gen 2)

|
|
* Demonstrates the concept of preventing semantic bleed by using physically
|
|
* isolated SQLite vector databases instead of dumping all embeddings into a
|
|
* single database. We use actual SQLite databases for this in Gen 2.
