+
+# RAG Engine Build Workflow — PolicyDecoder
+
+## Project Context
+Python RAG engine for PolicyDecoder AI.
+Folder: `rag_engine/` inside the monorepo root.
+Branch: `feat/rag-engine`
+
+## Rules the Agent Must Follow
+1. ALL Python files go inside `rag_engine/` — never outside it.
+2. Never touch `main` branch — always stay on `feat/rag-engine`.
+3. Every new file must have a module docstring at the top.
+4. Use `pydantic-settings` for all config — never hardcode API keys.
+5. Never write frontend, backend, API routing, or deployment code.
+6. Every class must have a docstring explaining its responsibility.
+7. After creating files, always run `python -m pytest rag_engine/tests/ -v`
+8. Always use `from utils.logger import get_logger` for logging.
+9. Never commit `.env` — only `.env.example`.
+10. Commit after EVERY agent prompt task completes — not after entire phases.
+    One logical unit of work = one git commit. Never bundle multiple
+    unrelated changes into a single commit.
+11. Always run tests before committing:
+    `python -m pytest rag_engine/tests/ -v`
+    Never commit if tests are failing.
+12. Stage ONLY the files created or modified in the current task.
+    Never use: `git add .`
+    Always use: `git add <specific-files-or-folders>`
+    This prevents accidentally staging .env or unrelated changes.
+13. Commit message format (Conventional Commits standard):
+    `feat(rag): short description`       ← new functionality
+    `fix(rag): short description`        ← bug fix
+    `test(rag): short description`       ← test files only
+    `chore(rag): short description`      ← config, deps, non-code
+    `refactor(rag): short description`   ← restructure, no behaviour change
+    `docs(rag): short description`       ← README, docstrings only
+14. After every commit, push immediately:
+    `git push origin feat/rag-engine`
+15. Never commit these files ever:
+    `.env`, `__pycache__/`, `*.pyc`, `.venv/`
+    If you accidentally stage .env: `git reset HEAD .env`
+
+## Tech Stack
+- Python 3.11+
+- llama-parse for PDF parsing
+- Supabase pgvector (via langchain-community SupabaseVectorStore) for vector storage
+- LangChain + langchain-openai for retrieval
+- Kimi K2.5 via Moonshot AI OpenAI-compatible API (base_url: https://api.moonshot.ai/v1)
+- openai Python SDK with custom base_url for Kimi
+- sentence-transformers (BAAI/bge-large-en-v1.5, 768-dim) for embeddings
+  LOCAL model — zero API cost, no key needed
+  Fallback: Jina Embeddings v3 API (jina-embeddings-v3, needs JINA_API_KEY)
+- pydantic v2 + pydantic-settings for schemas
+- tiktoken for token counting
+- pytest for testing
+
+## Vector Store Notes
+- Supabase pgvector is used — NOT ChromaDB
+- Policy isolation is done via metadata JSONB column: metadata->>'policy_id'
+- The table name is: policy_chunks
+- Embedding dimension: 768 (BAAI/bge-large-en-v1.5 local default)
+  If switching to Jina: 1024. If switching to OpenAI: 1536.
+
+## LLM Notes
+- Primary LLM: Kimi K2.5 via Moonshot AI
+- API base: https://api.moonshot.ai/v1
+- Model name: kimi-k2.5
+- API is OpenAI-compatible — use ChatOpenAI from langchain-openai with custom base_url
+- Fallback LLM: GPT-4o via OpenAI (same interface, just change base_url + model)
+
+## Phases
+- Phase 1: Parsing & Chunking (ingestion/, chunking/, schemas/chunk_metadata.py)
+- Phase 2: Embedding pipeline (embeddings/)
+- Phase 3: Vector storage (vector_store/ using Supabase pgvector)
+- Phase 4: Retrieval logic (retrieval/)
+- Phase 5: Prompt system + Kimi K2.5 LLM (prompts/, llm/)
+- Phase 6: End-to-end service (services/, main.py)
+- Phase 7: Evaluation & tuning (tests/)

+
+AsyncKit provides harness for `parallel` and `serial` iterators over list of items represented by arrays or objects.
+Optionally it accepts abort function (should be synchronously return by iterator for each item), and terminates left over jobs upon an error event. For specific iteration order built-in (`ascending` and `descending`) and custom sort helpers also supported, via `asynckit.serialOrdered` method.
+
+It ensures async operations to keep behavior more stable and prevent `Maximum call stack size exceeded` errors, from sync iterators.

+
+## Install
+
+```sh
+$ npm install --save asynckit
+```
+
+## Examples
+
+### Parallel Jobs
+
+Runs iterator over provided array in parallel. Stores output in the `result` array,
+on the matching positions. In unlikely event of an error from one of the jobs,
+will terminate rest of the active jobs (if abort function is provided)
+and return error along with salvaged data to the main callback function.
+
+#### Input Array
+
+```javascript
+var parallel = require('asynckit').parallel
+  , assert   = require('assert')
+  ;
+
+var source         = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
+  , expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]
+  , expectedTarget = [ 1, 1, 2, 4, 8, 16, 32, 64 ]
+  , target         = []
+  ;
+
+parallel(source, asyncJob, function(err, result)
+{
+  assert.deepEqual(result, expectedResult);
+  assert.deepEqual(target, expectedTarget);
+});
+
+// async job accepts one element from the array
+// and a callback function
+function asyncJob(item, cb)
+{
+  // different delays (in ms) per item
+  var delay = item * 25;
+
+  // pretend different jobs take different time to finish
+  // and not in consequential order
+  var timeoutId = setTimeout(function() {
+    target.push(item);
+    cb(null, item * 2);
+  }, delay);
+
+  // allow to cancel "leftover" jobs upon error
+  // return function, invoking of which will abort this job
+  return clearTimeout.bind(null, timeoutId);
+}
+```
+
+More examples could be found in [test/test-parallel-array.js](test/test-parallel-array.js).
+
+#### Input Object
+
+Also it supports named jobs, listed via object.
+
+```javascript
+var parallel = require('asynckit/parallel')
+  , assert   = require('assert')
+  ;
+
+var source         = { first: 1, one: 1, four: 4, sixteen: 16, sixtyFour: 64, thirtyTwo: 32, eight: 8, two: 2 }
+  , expectedResult = { first: 2, one: 2, four: 8, sixteen: 32, sixtyFour: 128, thirtyTwo: 64, eight: 16, two: 4 }
+  , expectedTarget = [ 1, 1, 2, 4, 8, 16, 32, 64 ]
+  , expectedKeys   = [ 'first', 'one', 'two', 'four', 'eight', 'sixteen', 'thirtyTwo', 'sixtyFour' ]
+  , target         = []
+  , keys           = []
+  ;
+
+parallel(source, asyncJob, function(err, result)
+{
+  assert.deepEqual(result, expectedResult);
+  assert.deepEqual(target, expectedTarget);
+  assert.deepEqual(keys, expectedKeys);
+});
+
+// supports full value, key, callback (shortcut) interface
+function asyncJob(item, key, cb)
+{
+  // different delays (in ms) per item
+  var delay = item * 25;
+
+  // pretend different jobs take different time to finish
+  // and not in consequential order
+  var timeoutId = setTimeout(function() {
+    keys.push(key);
+    target.push(item);
+    cb(null, item * 2);
+  }, delay);
+
+  // allow to cancel "leftover" jobs upon error
+  // return function, invoking of which will abort this job
+  return clearTimeout.bind(null, timeoutId);
+}
+```
+
+More examples could be found in [test/test-parallel-object.js](test/test-parallel-object.js).
+
+### Serial Jobs
+
+Runs iterator over provided array sequentially. Stores output in the `result` array,
+on the matching positions. In unlikely event of an error from one of the jobs,
+will not proceed to the rest of the items in the list
+and return error along with salvaged data to the main callback function.
+
+#### Input Array
+
+```javascript
+var serial = require('asynckit/serial')
+  , assert = require('assert')
+  ;
+
+var source         = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
+  , expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]
+  , expectedTarget = [ 0, 1, 2, 3, 4, 5, 6, 7 ]
+  , target         = []
+  ;
+
+serial(source, asyncJob, function(err, result)
+{
+  assert.deepEqual(result, expectedResult);
+  assert.deepEqual(target, expectedTarget);
+});
+
+// extended interface (item, key, callback)
+// also supported for arrays
+function asyncJob(item, key, cb)
+{
+  target.push(key);
+
+  // it will be automatically made async
+  // even it iterator "returns" in the same event loop
+  cb(null, item * 2);
+}
+```
+
+More examples could be found in [test/test-serial-array.js](test/test-serial-array.js).
+
+#### Input Object
+
+Also it supports named jobs, listed via object.
+
+```javascript
+var serial = require('asynckit').serial
+  , assert = require('assert')
+  ;
+
+var source         = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
+  , expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]
+  , expectedTarget = [ 0, 1, 2, 3, 4, 5, 6, 7 ]
+  , target         = []
+  ;
+
+var source         = { first: 1, one: 1, four: 4, sixteen: 16, sixtyFour: 64, thirtyTwo: 32, eight: 8, two: 2 }
+  , expectedResult = { first: 2, one: 2, four: 8, sixteen: 32, sixtyFour: 128, thirtyTwo: 64, eight: 16, two: 4 }
+  , expectedTarget = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
+  , target         = []
+  ;
+
+
+serial(source, asyncJob, function(err, result)
+{
+  assert.deepEqual(result, expectedResult);
+  assert.deepEqual(target, expectedTarget);
+});
+
+// shortcut interface (item, callback)
+// works for object as well as for the arrays
+function asyncJob(item, cb)
+{
+  target.push(item);
+
+  // it will be automatically made async
+  // even it iterator "returns" in the same event loop
+  cb(null, item * 2);
+}
+```
+
+More examples could be found in [test/test-serial-object.js](test/test-serial-object.js).
+
+_Note: Since _object_ is an _unordered_ collection of properties,
+it may produce unexpected results with sequential iterations.
+Whenever order of the jobs' execution is important please use `serialOrdered` method._
+
+### Ordered Serial Iterations
+
+TBD
+
+For example [compare-property](compare-property) package.

+Helper functions around Function call/apply/bind, for use in `call-bind`.
+
+The only packages that should likely ever use this package directly are `call-bind` and `get-intrinsic`.
+Please use `call-bind` unless you have a very good reason not to.
+
+## Getting started
+
+```sh
+npm install --save call-bind-apply-helpers
+```
+
+## Usage/Examples
+
+```js
+const assert = require('assert');
+const callBindBasic = require('call-bind-apply-helpers');
+
+function f(a, b) {
+	assert.equal(this, 1);
+	assert.equal(a, 2);
+	assert.equal(b, 3);
+	assert.equal(arguments.length, 2);
+}
+
+const fBound = callBindBasic([f, 1]);
+
+delete Function.prototype.call;
+delete Function.prototype.bind;
+
+fBound(2, 3);
+```
+
+## Tests
+
+Clone the repo, `npm install`, and run `npm test`
