_Thinking:_

No output again. Let me check if the glob pattern is right:

**Tool: bash**

**Input:**
```json
{
  "command": "podman exec marker-api find /app/marker_output -name \"*.json\" 2>/dev/null | head -3 && echo \"---\" && podman exec marker-api ls /app/marker_output/0ca1a846/ 2>/dev/null",
  "description": "Find JSON files directly"
}
```

**Output:**
```

Interesting! The output is nested two directories deep. The `glob` pattern `*/*.json` doesn't match `*/*/*.json`. Let me read the right file.

**Tool: bash**

**Input:**

_Thinking:_

Now I see the marker output structure clearly. The text is not stored in `text` or `content` fields directly - it's stored in the `html` field! The marker output uses HTML representation for each block's content.

So I need to extract text from the `html` field instead, using markdownify or BeautifulSoup to convert HTML to text. Let me check what's in the `html` field and how to extract text from it.

Actually, looking at the `children` of each block... the text might also be stored as part of the HTML tree, not as separate `text` fields. Let me look at the HTML content in a leaf node.

**Tool: bash**

**Input:**
```json
{
  "command": "podman exec marker-api python3 -c \"\nimport json, glob\njf = glob.glob('/app/marker_output/*/*/*.json')\nif jf:\n    with open(jf[0]) as f:\n        t = json.load(f)\n    # Show HTML of first child of first page\n    p0 = t['children'][0]\n    for c in p0.get('children', [])[:3]:\n        if isinstance(c, dict):\n            html = c.get('html', '')\n            print(f'--- Block type={c.get(\\\"block_type\\\")} ---')\n            print(html[:300])\n            print()\n            # Check for deeper children\n            for cc in (c.get('children') or [])[:2]:\n                if isinstance(cc, dict):\n                    html2 = cc.get('html', '')\n                    bbox = cc.get('bbox', '')\n                    print(f'  Child type={cc.get(\\\"block_type\\\")}: html={html2[:200]!r}, bbox={bbox}')\n\" 2>&1",

_Thinking:_

Now I see! The marker output uses `html` fields with HTML markup. The text is embedded in HTML tags like `<h2><b>NATO STANDARD</b></h2>`. The blocks don't have `text` or `content` fields - the content is in the `html` field.

I need to extract text from the HTML. The simplest way is to use the `html2text` library, `markdownify`, or just use a simple regex/strip_tags approach. Since we already have `markdownify` as a dependency (from marker-pdf's requirements), let me use that.

But actually, the simplest approach is to just strip HTML tags manually using `re.sub(r'<[^>]+>', '', html)` and then clean up the whitespace.

Let me update the `extract_text` function in `_run_marker` to use the `html` field:

_Thinking:_

Now let me also make sure the `blocks` field in the page entries uses `html` for the text_lines. Actually, `text_lines` is already using `extract_text` which now extracts from HTML. Good.

But wait - I'm also putting raw child dicts into `blocks`. These raw children have `html`, `bbox`, `polygon`, `block_type` keys. The `parse_marker_json` function has been updated to use `text_lines` instead of `blocks`, so this should be fine.

Let me update the container and test:

**Tool: bash**

**Input:**
```json
{
  "command": "podman exec -i marker-api bash -c \"cat > /app/server.py\" < /home/oval/Projects/agentic/marker-api/server.py && podman restart marker-api 2>&1 && sleep 5",

_Thinking:_

Good progress! We have 1406 chars total, and page 0 has 235 chars. But pages 1 and 2 show 0 chars - let me investigate. The HTML content for those pages might be structured differently.

Actually, let me look more carefully at the debug output from earlier. Page 1 has:
- 2 grandkids: PageHeader and PageFooter - both might have empty HTML or their children aren't being traversed.

The issue might be that `extract_text` returns the HTML of the immediate child but doesn't recursively process its children. Wait, it DOES process children - but it first checks if the node has HTML. If a SectionHeader or PageHeader has HTML, it returns that. If it doesn't have HTML, it processes children.

Let me check if the PageHeader/PageFooter have HTML or rely on their children:

**Tool: bash**

**Input:**
```json
{
  "command": "podman exec marker-api python3 -c \"\nimport json, glob\njf = glob.glob('/app/marker_output/*/*/*.json')\nif jf:\n    with open(jf[0]) as f:\n        t = json.load(f)\n    p1 = t['children'][1]  # Second page (index 1)\n    for c in p1.get('children', []):\n        if isinstance(c, dict):\n            bt = c.get('block_type','')\n            html = c.get('html','')\n            print(f'Block type={bt}: html={html[:200]!r}')\n            # Check children\n            for cc in (c.get('children') or [])[:3]:\n                if isinstance(cc, dict):\n                    html2 = cc.get('html','')\n                    print(f'  Child type={cc.get(\\\"block_type\\\")}: html={html2[:200]!r}')\n\" 2>&1",

## Assistant (Build · DeepSeek V4 Flash Free · 5.9s)

_Thinking:_

PageHeader and PageFooter have empty HTML, and their children might have the actual text. But I'm not checking deeper than one level in `extract_text`. Let me trace through the logic:

For a PageHeader dict with `html=''` and `children`:
1. `html` is empty/falsy, so skip
2. Process children - they might have HTML

The issue is that `html` might be `''` (empty string), so `if html:` is False, and we look at children. But the children might also not have direct HTML, requiring deeper recursion.

Actually, `extract_text` does recursively process children. So if a PageHeader has children that have HTML, it should eventually find it. Let me verify the walking is correct by looking at what `extract_text` returns for a PageHeader:

**Tool: bash**

**Input:**
```json
{
  "command": "podman exec marker-api python3 -c \"\nimport json, glob, re\njf = glob.glob('/app/marker_output/*/*/*.json')\nif jf:\n    with open(jf[0]) as f:\n        t = json.load(f)\n    p1 = t['children'][1]  # Second page\n    for c in p1.get('children', []):\n        if isinstance(c, dict):\n            bt = c.get('block_type','')\n            # Recursively extract text\n            def extract(node):\n                if isinstance(node, dict):\n                    html = node.get('html','')\n                    if html:\n                        txt = re.sub(r'<[^>]+>','',html)\n                        txt = re.sub(r'\\s+',' ',txt).strip()\n                        if txt: return txt\n                    for ch in (node.get('children') or []):\n                        r = extract(ch)\n                        if r: return r\n                    return ''\n                return ''\n            txt = extract(c)\n            print(f'Block {bt}: extracted={txt[:80]!r}')\n            # Show children\n            for cc in (c.get('children') or [])[:5]:\n                if isinstance(cc, dict):\n                    html2 = cc.get('html','')\n                    print(f'  Child {cc.get(\\\"block_type\\\")}: html={html2[:100]!r}')\n                    for ccc in (cc.get('children') or [])[:2]:\n                        if isinstance(ccc, dict):\n                            print(f'    Grandchild {ccc.get(\\\"block_type\\\")}: html={ccc.get(\\\"html\\\",\\\"\\\")[:100]!r}')\n\" 2>&1",

_Thinking:_

So the PageHeader and PageFooter have no text content at all. That makes sense - the marker output creates empty headers/footers when it detects them. The actual text content for this page is probably in the next page (page 2). Let me check page 2 more carefully:

_Thinking:_

Good! Page 2 has 9 blocks with actual text content. But in my earlier test, the curl output showed only 9 lines and 0 chars for page 2. Wait, that's wrong - the curl test showed `Page 2: 9 lines, 1019 chars`. So it IS picking up the text for page 2.

And page 1 only has 2 lines (PageHeader and PageFooter) with 0 chars each - that's correct, they're empty.

So the output is correct for the existing code! The issue was just that `text_lines` for the PageHeader/PageFooter blocks have empty text. That's fine - they'll be filtered out by `parse_marker_json` which checks for empty content.

Now let me make sure the full pipeline works. I need to:
1. Clear old documents
2. Re-upload the NISP PDFs through the main app (which now uses the fixed marker-api)
3. Test the research endpoint

Let me first delete old documents and chunks, then restart the app, then upload.

_Thinking:_

Let me also delete the old documents from the database using Python since the UUID values are different. Actually, let me just restart the app container (which may have updated code) and then upload.

But first, I need to update the `batch_chunk` method to pass the vector as a string with `::vector` cast, like we did for `store_finding`. Actually, looking back, `batch_chunk` passes tuples of data to `executemany`, and the vector parameter `$3` is a list. But in the old upload, this appeared to work...

Wait, let me look more carefully. `batch_chunk` creates tuples of `(content, vector_list, page, idx, poly, ctype)` and inserts with `VALUES ($1, $2, $3, $4, $5, $6::jsonb, $7)`. So the SQL has these params:
- $1 = doc_id (from the function arg)
- $2 = content (from the tuple)
- $3 = vector (from the tuple - a list)
- $4 = page_num (from the tuple)
- $5 = block_index (from the tuple)
- $6 = polygon (from the tuple - jsonb cast)
- $7 = chunk_type (from the tuple)

But wait, the outer function parameter `doc_id` isn't passed in the `executemany` call! Let me check:

```python
async def batch_chunk(self, doc_id: str, data: list[dict]):
    vec_data = [(content, self._extract_vector(content), page, idx, poly, ctype)
                 for content, page, idx, poly, ctype in data]
    async with self.connection() as conn:
        await conn.executemany(
            """INSERT INTO chunks (doc_id, content, vector, page_num,
               block_index, polygon, chunk_type)
               VALUES ($1, $2, $3, $4, $5, $6::jsonb, $7)""",
            vec_data
        )
```

So `doc_id` is never passed to the query! The `vec_data` tuples have only 6 values: `(content, vector, page, idx, poly, ctype)`. These correspond to $1-$6 (since $1 would be the first element in the tuple). But the INSERT column list has 7 columns: doc_id, content, vector, page_num, block_index, polygon, chunk_type. Only the last 6 are being provided!

This is a bug that needs fixing. The `doc_id` is missing. But the old uploads succeeded (chunks were recorded)... Actually, looking at my test earlier, chunks count was 0 for the old upload. The upload `return` statement returned a result without checking if chunks were actually stored. So the chunks just weren't created at all (because of both the marker API format AND the doc_id issue).

Actually wait, looking at the upload result:
```python
return {**result, "doc_id": doc_id, "filename": filename, "strategy": "marker_ocr"}
```

The `result` is what `process_document_file` returns, which includes `"chunks": len(chunks)`. So it was reporting 0 chunks. The upload succeeded in storing the document record but the chunks weren't created.

And I checked earlier that chunks count was 0: `SELECT COUNT(*) FROM chunks WHERE doc_id='461fc0d1-...'` returned 0.

Now I need to fix `batch_chunk` to pass `doc_id`.

_Thinking:_

Wait, I'm adding `str(doc_id)` but the INSERT might expect `uuid` type. And the `vec_str` that I compute on line 107 is not actually used. Let me also double-check. Actually `str(doc_id)` should be fine for the `uuid` column since asyncpg can cast strings to UUID.

But looking at the `executemany` - the values are tuples and each element corresponds to a `$N` placeholder. With 7 values in each tuple ($1-$7):
- $1 = doc_id (str)
- $2 = content (str)
- $3 = vector (str, cast with ::vector)
- $4 = page_num (int)
- $5 = block_index (int)
- $6 = polygon (str or None, cast with ::jsonb)
- $7 = chunk_type (str)

That looks right. Let me also update the single `chunk_document` method to match:

_Thinking:_

Wait, the `chunk_document` function has the params numbered differently from `batch_chunk`. In `chunk_document`:
- $1 = chunk_id
- $2 = doc_id
- $3 = content
- $4 = vector
- $5 = page_num
- $6 = block_index
- $7 = polygon
- $8 = chunk_type

But I changed $4 to `$4::vector` which is correct.

Now let me update the files in containers and restart. But first let me clean up old documents so fresh uploads get new chunks.

**Tool: bash**

**Input:**
```json
{
  "command": "podman exec pv-db psql -U research -d research -c \"DELETE FROM chunks; DELETE FROM documents;\" 2>&1 && echo \"Old data cleared\"",

The `db` global in `database.py` is `None`. The processor imports `from app.db.database import db` which gets the module-level `db = None` variable. It never gets initialized.

Let me check how `db` is initialized. In `database.py`, there's likely a module-level `db` that's supposed to be set during app startup.

_Thinking:_

So `main.py` has its own `db_conn` variable that gets initialized during startup (lines 57-59). But the `processor.py` imports `from app.db.database import db` which is the MODULE-LEVEL `db = None` variable, never initialized.

The fix: I should change the processor to accept `db` as a parameter, or import `db_conn` from main.py, or better yet, initialize the module-level `db` in the Database module with a method.

Actually, the simplest fix is to have the processor use the module-level `db` from database.py and have the app's startup code set it. But currently `main.py` creates its own `db_conn` variable.

The cleanest fix: have `database.py` export a `get_db()` function that checks if the module-level `db` is initialized, and have both `main.py` and `processor.py` use it. Or simpler: just set `database.db` during startup.

Let me update `main.py` to set the module-level `db` variable during startup:

_Thinking:_

I need to set the module-level `db` variable in `database.py` during startup. The import chain is:

1. `processor.py` imports `from app.db.database import db`
2. `main.py` imports `from app.db.database import Database` (not `db`)

So I need to also import and set `db` from the `database` module. Or better, store the db reference somewhere accessible.

Let me simply add `import app.db.database as db_mod; db_mod.db = db_conn` to the startup function, or better yet, update the import in `processor.py` to get the `db_conn` from `main.py` or better yet use the `Database` class directly.

Wait, the simplest approach: in `database.py`, add a method to set the module-level `db`, and call it from `main.py`'s startup:

## Assistant (Build · DeepSeek V4 Flash Free · 4.2s)

_Thinking:_

The `db` is still `None`! The startup code sets `_db_mod.db = db_conn` but the import path might be different. The `processor.py` does `from app.db.database import db`, which creates a local reference. But `_db_mod.db = db_conn` sets it on the module. 

Wait, let me check the modules more carefully. `from app.db.database import db` imports the `db` NAME into the processor's module namespace. But `import app.db.database as _db_mod; _db_mod.db = db_conn` sets the module attribute. Since `from ... import db` creates a reference to `app.db.database.db`, and setting `_db_mod.db` modifies the same attribute, this should work.

Unless the import in processor.py happens AFTER `_db_mod.db = db_conn` was set, but with a different module object. Let me check if the database module is being imported differently.

Actually, let me check if the startup is completing without errors:

## Assistant (Build · DeepSeek V4 Flash Free · 6.1s)

_Thinking:_

The startup completes. But I see "Schema init (non-fatal): operator class..." - the init_schema runs but the ivfflat index creation fails. That's fine, tables are created.

The issue is that `_db_mod.db = db_conn` might be setting the module-level `db`, but the `processor.py` imported `from app.db.database import db` BEFORE the assignment. Since Python modules are singletons, the assignment `_db_mod.db = db_conn` should update the same `db` object that `processor.py` references.

Unless there's a timing issue... The imports happen at module load time, before `on_startup` runs. The `from ... import db` creates a local reference in processor.py's module. But `_db_mod.db = db_conn` modifies the database module's attribute. The local reference in processor.py points to the database module's `db` attribute. Wait no - `from X import Y` creates a NEW local variable `Y` that points to whatever `X.Y` was at import time. It does NOT create a reference to the module attribute.

So `from app.db.database import db` in `processor.py` creates `processor.db = None` (the value at import time). Setting `app.db.database.db = db_conn` later doesn't update `processor.db`.

The fix is to either:
1. In `processor.py`, use `from app.db import database` and access `database.db` (module reference, not copied value)
2. Or pass `db` as a parameter to `MarkerProcessor`
3. Or have the processor use `database.get_db()` function

The simplest: update `processor.py` to import the module and access `db` through it:

**Tool: edit**

**Input:**
```json
{
  "filePath": "/home/oval/Projects/agentic/app/core/processor.py",
  "oldString": "from app.config import get_settings\nfrom app.db.database import db",
  "newString": "from app.config import get_settings\nimport app.db.database as _db_mod\ndb = _db_mod.db"
}

## Assistant (Build · DeepSeek V4 Flash Free · 4.4s)

_Thinking:_

Now `db` in processor.py is a reference to `_db_mod.db`, which will resolve at CALL TIME (when `db.batch_chunk()` is called), not at import time. This is because `processor.db` is a module-level variable that's set to `_db_mod.db` at import time, but `_db_mod.db` can be updated later.

Wait, actually that still won't work. `processor.db = _db_mod.db` copies the VALUE of `_db_mod.db` at import time (which is `None`). Later changes to `_db_mod.db` won't be reflected.

I need to use `_db_mod.db` directly in the function, or use a property/function.

The proper fix: change `processor.py` to use `_db_mod.db` directly instead of saving to a local variable:

## Assistant (Build · DeepSeek V4 Flash Free · 7.7s)

_Thinking:_

The error is in the `executemany` call. Let me look at the `batch_chunk` function:

```python
async def batch_chunk(self, doc_id: str, data: list[dict]):
    vec_data = [(str(doc_id), content,
                 "[" + ",".join(str(x) for x in self._extract_vector(content)) + "]",
                 page, idx, json.dumps(poly) if poly else None, ctype)
                for content, page, idx, poly, ctype in data]
```

The issue is that `page` is a tuple of `(content, page_num, block_index, polygon, chunk_type)` from `data`. Let me check the data structure in the processor:

```python
for page in pages:
    for block_idx, tl in enumerate(text_lines):
        ...
        chunks.append({
            "content": content.strip(),
            "page_num": page_num,
            "block_index": block_idx,
            "polygon": polygon,
            "chunk_type": block_type,
        })
```

And in `parse_marker_json`:
```python
chunks.append({
    "content": content.strip(),
    "page_num": page_num,
    "block_index": block_idx,
    "polygon": polygon,
    "chunk_type": block_type,
})
```

Then `batch_chunk` unpacks `data` as:
```python
for content, page, idx, poly, ctype in data
```

Wait, that's wrong! `data` is a list of dicts, not tuples. The unpacking `for content, page, idx, poly, ctype in data` tries to iterate over the dict VALUES. But dicts in Python iterate over keys. So `content` would be the first key ("content"), `page` would be the second key ("page_num"), etc.

This is a fundamental bug: `data` is a list of dicts, but `batch_chunk` treats it as a list of tuples. Let me fix it properly:

## Assistant (Build · DeepSeek V4 Flash Free · 3.6s)

_Thinking:_

The document record needs to be created BEFORE the chunks. Looking at the upload flow:

1. `upload_document` creates `doc_id`
2. Calls `processor.process_document_file(file_data, filename, doc_id)` - which calls `batch_chunk`
3. Then calls `db_conn.upsert_document(...)` - which inserts the document record

The problem is that chunks reference a doc_id that doesn't exist yet in the documents table. I need to either:
1. Insert the document record BEFORE processing
2. Or make the FK constraint deferred

Let me fix the upload flow to insert the document record first:

_Thinking:_

I need to create the document record BEFORE calling `processor.process_document_file`. Let me add a `create_document` method or just use `upsert_document` before processing.

Looking at the code, `upsert_document` does an INSERT or UPDATE by doc_id/text_id. Let me check its implementation:

**Tool: bash**

**Input:**
```json
{
  "command": "podman exec agentic-app python3 -c \"\nimport inspect\nfrom app.db.database import Database\nprint(inspect.getsource(Database.upsert_document))\n\" 2>&1",

        full_text: str, metadata: dict
    ) -> str:
        async with self.connection() as conn:
            doc_uuid = str(uuid.uuid4())
            await conn.execute(
                """INSERT INTO documents (id, filename, doc_id, mime_type, file_path,

                   ON CONFLICT (filename) DO UPDATE SET
                   status=EXCLUDED.status, page_count=EXCLUDED.page_count,

                status, page_count, full_text, json.dumps(metadata),
            )
            return doc_uuid


```

## Assistant (Build · DeepSeek V4 Flash Free · 9.4s)

_Thinking:_

I see! `upsert_document` generates its own UUID: `doc_uuid = str(uuid.uuid4())`. But upload generates `doc_id = str(uuid.uuid4())` which is passed as `doc_id` parameter. These are different! So the `doc_id` param in `upsert_document` is actually the `text_id` or some external reference, not the primary key.

Looking at the SQL:
```sql
INSERT INTO documents (id, filename, doc_id, ...)
VALUES ($1, $2, $3, ...)
```

The `id` column is the primary key (the internal UUID), and `doc_id` is a separate column. The `chunks.doc_id` FK references `documents.id` (the primary key).

So the fix is: I need to know the `documents.id` (the PK) before inserting chunks. I can either:
1. Pass the PK directly to `process_document_file` 
2. Or have `process_document_file` return the PK
3. Or create the document record first with a known PK

The simplest approach: create the document record first in the upload function, then pass the real `documents.id` PK to the processor.

Actually, looking at the upload flow more carefully:

1. `doc_id = str(uuid.uuid4())` - this is the `documents.id`
2. `processor.process_document_file(file_data, filename, doc_id)` - this calls `batch_chunk(doc_id, chunks)` which uses `doc_id` as the FK to `documents.id`
3. `upsert_document(filename, result.get("doc_id"), ...)` - this generates a NEW UUID as `documents.id` and ignores the original `doc_id`

So there's a mismatch: `batch_chunk` uses the original `doc_id` as the FK, but `upsert_document` creates a new UUID as the PK.

The fix: either:
A. Have `process_document_file` also create the document record
B. Or create the doc record first and pass the UUID to the processor
C. Or fix `upsert_document` to use the passed `doc_id` as the PK

Let me go with option A: have the processor create the document record first, then batch_chunk. But that couples the processor to the document creation logic.

Actually, the simplest approach: create the document in the upload endpoint BEFORE calling the processor, then pass the real PK.

_Thinking:_

Now I also need to fix `upsert_document` to use the passed `doc_id` as the primary key instead of generating its own UUID. Let me check the current signature: `upsert_document(self, filename: str, doc_id: str | None, ...)` - where `doc_id` here is meant to be the primary key `documents.id`.

But looking at the SQL, it generates `doc_uuid = str(uuid.uuid4())` and uses that as `$1` (the `id` column). The `doc_id` parameter goes to `$3` (also called `doc_id` column). So the column `doc_id` in the documents table is a separate field from the PK `id`.

This is confusing. Let me look at the schema:

_Thinking:_

Now I see the full picture:
- `documents.id` (UUID PK) - referenced by `chunks.doc_id`, `findings.session_id`, `memories.session_id`, `memories.source_doc_id`
- `documents.doc_id` (TEXT) - a separate document identifier, not the PK
- `documents.filename` (TEXT, UNIQUE)

The FK `chunks_doc_id_fkey` references `documents.id`. So when `batch_chunk` stores chunks with `doc_id=doc_uuid`, it must match a value in `documents.id`.

In my fix, I:
1. Generate `doc_uuid = str(uuid.uuid4())` 
2. Call `upsert_document` which creates a document WITH `doc_uuid` as... wait. `upsert_document` generates its own `doc_uuid = str(uuid.uuid4())` and uses that for `$1` (the `id` column). My `doc_uuid` is passed as `$3` (the `doc_id` column, not the PK).

So there are TWO different UUIDs:
- `documents.id` (PK) = the one generated inside `upsert_document`
- `documents.doc_id` (TEXT) = the one I pass to `upsert_document`

And `chunks.doc_id` references `documents.id`, not `documents.doc_id`.

So I need to either:
1. Make `upsert_document` use the passed `doc_id` as the PK `id`
2. Or return the PK from `upsert_document` and use it for chunks

Let me fix `upsert_document` to use the `doc_id` parameter as the PK when provided:

_Thinking:_

Wait, I changed the SQL to use `$1` for both `id` and `doc_id` columns. That means `doc_id` (the TEXT column) will be the same as `id` (the UUID PK). That should be fine - the TEXT column can hold a UUID string.

But I also removed the `doc_id` parameter from the VALUES clause (since both `id` and `doc_id` use `$1`). Let me double check:

Old SQL: `VALUES ($1, $2, $3, $4, $5, $6, $7, $8, $9::jsonb)` - 9 params
New params: `pk, filename, mime_type, file_path, status, page_count, full_text, json.dumps(metadata)` - 8 params
New SQL: `VALUES ($1, $2, $1, $3, $4, $5, $6, $7, $8::jsonb)` - need to check count

Let me count: `$1, $2, $1, $3, $4, $5, $6, $7, $8::jsonb` - that's 8 unique parameters ($1-$8), and the VALUES clause has 9 items. But I'm passing 8 parameters: `pk, filename, mime_type, file_path, status, page_count, full_text, json.dumps(metadata)`.

So:
- $1 = pk → used for both `id` and `doc_id`
- $2 = filename
- $3 = mime_type
- $4 = file_path
- $5 = status
- $6 = page_count
- $7 = full_text
- $8 = json.dumps(metadata) → ::jsonb

That's correct: 8 params for 9 placeholders ($1 used twice).

## Assistant (Build · DeepSeek V4 Flash Free · 5.1s)

_Thinking:_

The issue is that `$1` is used for both `id` (UUID type) and `doc_id` (TEXT type), but PostgreSQL can't deduce a consistent type for `$1` when it's used in two columns of different types. The first use determines the type (UUID), but then the second use in `doc_id` expects TEXT.

I need to explicitly cast: `$1::text` for the doc_id column.

## Assistant (Build · DeepSeek V4 Flash Free · 5.5s)

_Thinking:_

Actually wait, `$1::uuid` converts the string to UUID for the `id` column, and `$1` (text) for the `doc_id` column. But now there's a problem: `$1` is used for both a UUID-cast column and a text column. PostgreSQL can infer `$1` as text (since it's used as text in doc_id), and then `$1::uuid` converts it.

Actually, let me think about this differently. Since both `id` and `doc_id` have different types, I should use separate parameters. But I was trying to use the same value for both columns.

The simplest solution: just pass the value twice, once as UUID and once as text:

## Assistant (Build · DeepSeek V4 Flash Free · 6.1s)

_Thinking:_

Actually, `$1::uuid` and `$1::text` should be fine because PostgreSQL can still type-deduce `$1` as text (since both casts are explicit, it can treat $1 as unknown and let the casts resolve). But actually, PostgreSQL with asyncpg might still infer $1 as UUID from the first use. Let me try a different approach: use two separate parameters.

Or even simpler: don't bother with the `doc_id` text column. Just make both `id` and `doc_id` the same UUID value and avoid the type conflict by passing the value as a string and casting at the SQL level.

Let me just pass `str(pk)` for both:

_Thinking:_

The pipeline is running, but the evidence extraction returned empty results. This is because the document chunks might not contain the phrase "interoperability standards" in a way that the LLM can extract. Let me try a simpler query or check the actual chunk content to see what the document contains.

But the pipeline IS working - it's running all three stages and returning structured results. The issue is that the evidence has no rows, which suggests the document chunks don't contain the expected content.

Let me verify chunks exist and check their content:

**Tool: bash**

**Input:**
```json
{
  "command": "podman exec pv-db psql -U research -d research -c \"SELECT substring(content, 1, 120) FROM chunks WHERE doc_id='6098831b-c0a7-4e00-89a2-8455318418c4' LIMIT 5;\" 2>&1",
  "description": "Check chunk content for Vol 1"
}
```

**Output:**
```

_Thinking:_

The chunks contain relevant content like "NATO Interoperability Standards and Profiles" but the pipeline returned empty evidence. The issue might be with how the LLM processes the chunks in the pipeline mode, or the LLM (gpt-oss:20b) might not be extracting properly.

Let me try with a different, simpler query:

**Tool: bash**

_Thinking:_

The pipeline is running end-to-end, but the evidence extraction is not picking up any content. The issue might be:
1. The `read_chunks` tool or `vector_search` tool doesn't return proper content for the pipeline mode
2. The LLM prompt format isn't optimized for the chunk data
3. The LLM (gpt-oss:20b) doesn't properly follow the evidence extraction format

Let me try the flat `researcher` or `qa_agent` skills which are simpler:

**Tool: bash**

**Input:**
```json
{
  "command": "curl -s --max-time 600 -X POST http://localhost:8000/api/research/run \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"query\":\"What is ADatP-34 and what does it contain?\",\"doc_id\":\"6098831b-c0a7-4e00-89a2-8455318418c4\",\"skills\":[\"qa_agent\"]}' 2>&1 | python3 -c \"\nimport json,sys\nd = json.load(sys.stdin)\nresults = d.get('results', {})\nfor skill, text in results.items():\n    print(f'=== {skill} ===')\n    print(text[:800] if text else '(empty)')\n\"",

```

**Output:**
```
=== qa_agent ===
**Q:** What is ADatP‑34 and what does it contain?

**A:** I was unable to locate any document, database entry, or public record that references “ADatP‑34.” Consequently, I cannot provide a definitive description or contents of such an item. It may be an internal designation, a placeholder, or a reference that was not captured in the available data set.

**Sources:** No documents were retrieved. Search attempts (`vector_search`, `text_search`, `read_chunks`, `get_page_text`) returned errors because no document ID was supplied.

**Uncertainty:** High – the absence of evidence in the provided corpus means the answer is based solely on the lack of data, not on any confirmed information.

_Thinking:_

The issue is that the tool outputs say "no document ID was supplied". Looking at the engine, the `doc_id` is being passed correctly but the tool dispatch might be wrong for the pipeline mode. Let me check the `run_skill` function - it passes `doc_id` as `kwargs["doc_id"]` for tools that accept it, but there might be an issue.

Let me check the tools and what they receive:

_Thinking:_

Looking at this code, for `vector_search` and `text_search`, we check `"doc_id" in sig.parameters` before passing it. Let me check the signature of `vector_search`:

**Tool: bash**

**Input:**
```json
{
  "command": "podman exec agentic-app python3 -c \"\nimport app.agents.tools as t\nimport inspect\nprint('vector_search sig:', inspect.signature(t.vector_search))\nprint('text_search sig:', inspect.signature(t.text_search))\nprint('read_chunks sig:', inspect.signature(t.read_chunks))\nprint('get_page_text sig:', inspect.signature(t.get_page_text))\n\" 2>&1",
  "description": "Check tool signatures"
}
```

**Output:**
```
vector_search sig: (query: 'str', doc_id: 'str | None' = None, limit: 'int' = 20) -> 'str'
text_search sig: (query: 'str', doc_id: 'str | None' = None, limit: 'int' = 20) -> 'str'
read_chunks sig: (doc_id: 'str', page_num: 'int | None' = None, limit: 'int' = 50) -> 'str'
get_page_text sig: (doc_id: 'str', page_num: 'int') -> 'str'

```

## Assistant (Build · DeepSeek V4 Flash Free · 6.3s)

_Thinking:_

I see! All these functions have `doc_id` in their signature (for search, it has `doc_id: str | None = None`). So the check `"doc_id" in sig.parameters` would pass for ALL of them. But the issue is that `vector_search` passes `query` as a POSITIONAL argument, and `doc_id` as keyword. So the dispatch should work.

Wait, the issue might be with `read_chunks` - it's handled on line 83-84: `await tool_fn(doc_id, limit=20)` - passing `doc_id` as positional which is correct since `read_chunks(doc_id, ...)`.

Let me check: is `doc_id` being passed correctly as a non-empty string? Looking at line 83: `if tool_name == "read_chunks" and doc_id:` - this checks that `doc_id` is truthy (non-empty). And at line 84: `result = await tool_fn(doc_id, limit=20)` - it passes `doc_id` as the first positional arg.

This should work. Let me check what happens with `qa_agent` which uses `vector_search`, `text_search`, `read_chunks`, `get_page_text`. From the error: "Search attempts returned errors because no document ID was supplied" - this is coming from the LLM response, which means the `vector_search` tool ran but returned empty results (the LLM interpreted "no document ID" from the output).

Wait, no - the error says "attempts returned errors because no document ID was supplied". This text is from the LLM's response, not from the actual tool error. So the tools ran fine, returned something, but the LLM interpreted the output as indicating no document ID was present.

Let me check what the `vector_search` tool returns:

**Tool: bash**

**Input:**
```json
{
  "command": "# Test vector_search directly\ncurl -s \"http://localhost:8000/api/research/semantic?query=ADatP-34&doc_id=6098831b-c0a7-4e00-89a2-8455318418c4&limit=3\" 2>&1 | head -c 500",

## Assistant (Build · DeepSeek V4 Flash Free · 3.5s)

_Thinking:_

The `vector_search` SQL has `doc_id = $1` where $1 is `str(doc_id)`. But `doc_id` column in `chunks` is `uuid` type, not text. So `str(doc_id)` as a string should still work because PostgreSQL can compare UUID with text via implicit cast.

Wait, but actually the chunks table has `doc_id` as `uuid` type referencing `documents.id`. Let me check:

**Tool: bash**

**Input:**
```json
{
  "command": "podman exec pv-db psql -U research -d research -c \"\\d chunks\" 2>&1 | grep doc_id",

    "chunks_doc_id_fkey" FOREIGN KEY (doc_id) REFERENCES documents(id) ON DELETE CASCADE

```

`chunks.doc_id` is UUID type, and `str(doc_id)` should work since asyncpg can pass a string for a UUID column.

asyncpg.exceptions.DataError: different vector dimensions 1536 and 4096

```

## Assistant (Build · DeepSeek V4 Flash Free · 5.6s)

_Thinking:_

The vector dimension mismatch: the query embedding has 4096 dimensions (from `qwen3-embedding:8b`) but the chunks have 1536 dimensions (from the hash-based `_extract_vector`). This mismatch will cause errors in vector search.

The chunks were created with `_extract_vector` which produces 1536-dim vectors. But the `/api/research/semantic` endpoint uses `get_embedding_sync` which calls Ollama's `qwen3-embedding:8b` which produces 4096-dim vectors.

The root cause: the hash-based `_extract_vector` produces 1536-dim vectors for chunks, but the Ollama embedding model produces 4096-dim vectors for queries.

The vector column in the DB is `vector(1536)`. So when we try to compare a 4096-dim query vector with 1536-dim stored vectors, it fails.

I need to make the dimensions consistent. Options:
1. Change `_extract_vector` to produce the same dimension as the Ollama embedding model (4096)
2. Or change the vector column to 4096 and update chunks
3. Or truncate/pad one to match the other

The cleanest fix: update `_extract_vector` to produce 4096-dim vectors to match the embedding model, and drop/recreate the chunks with the new dimension.

But first, let me check what dimension the embedding model actually produces. Let me also check what embedding model is configured.

**Tool: bash**

**Input:**
```json
{
  "command": "podman exec agentic-app python3 -c \"\nfrom app.core.embedding_engine import get_embedding\nvec = get_embedding('test')\nprint(f'Dimension: {len(vec) if vec else 0}')\nprint(f'First 5: {vec[:5]}')\n\" 2>&1",
  "description": "Check embedding vector dimension",
  "timeout": 30000
}
```

**Output:**
```
Dimension: 4096
First 5: [0.027887182, 0.013145617, -0.0067506246, -0.014297382, 0.022811804]

```

## Assistant (Build · DeepSeek V4 Flash Free · 5.2s)

_Thinking:_

So the embedding model produces 4096-dim vectors. The `_extract_vector` function produces 1536-dim vectors. This mismatch causes all vector operations to fail.

I need to:
1. Change the VECTOR_DIM config from 1536 to 4096
2. Update `_extract_vector` to produce 4096-dim vectors
3. Drop and recreate the chunks (or alter the column type)

But wait - the chunks are already stored with 1536-dim vectors. I'd need to either:
- Re-create the chunks with the correct dimension
- Or alter the table column type

Given that we have few documents, the simplest approach: change the dimension, delete old chunks, re-upload.

Actually, the problem is more fundamental. The `_extract_vector` function is a fallback for when embedding API isn't available. But the chunks I uploaded used `_extract_vector` which produces 1536-dim vectors. The vector_search query uses the embedding API which produces 4096-dim vectors.

Let me fix the dimension issue:

_Thinking:_

There are TWO different fallback vector implementations:
1. `_hash_embedding` in `embedding_engine.py` - uses MD5, 1536-dim (called when Ollama is unavailable)
2. `_extract_vector` in `database.py` - uses Python's hash(), 1536-dim (used by `store_finding`, `chunk_document`, `batch_chunk`)

I need to:
1. Change `vector_dim` in config to 4096
2. Update `_hash_embedding` to produce 4096-dim
3. Update `_extract_vector` in database.py to produce 4096-dim
4. Change the DB column types from `vector(1536)` to `vector(4096)`

Now update the container files and restart. I also notice duplicate line 76 in init.sql (`CREATE INDEX IF NOT EXISTS idx_chunks_doc ON chunks(doc_id);` appears twice). But that's a minor issue, not critical.

**[OBJECTIVE]**  
Determine the purpose of NISP and identify the standards it references.

1. What is the primary purpose or objective of NISP?  
2. Which formal standards, guidelines, or frameworks does NISP explicitly reference or rely upon?  
3. How does NISP align its purpose with those referenced standards?  
4. Are there any specific implementation or compliance requirements linked to the referenced standards?

**[CLASSIFICATION]**  
| doc_name | Classification | Reas

**Question**  
What is the purpose of NISP and what standards does it reference?

**Short answer**  
The current corpus contains no extracted evidence that describes the purpose of NISP or the standards it references.

**Key findings**  
| Finding | Source anchor |
|---------|---------------|
| No extracted evidence available | — |

**Conflicting evidence**  
None – no evidence was found.

**Gaps**  
- Lack of any document or excerpt that defines NISP or lists its referenced

## Assistant (Build · DeepSeek V4 Flash Free · 5.1s)

_Thinking:_

The pipeline mode is executing all three stages. Document triage produces sub-questions and classification, evidence extraction returns empty rows, and synthesis reports no evidence. The problem is that `evidence_extraction` is not extracting any rows.

This is likely because the LLM (gpt-oss:20b) isn't following the evidence extraction format properly, or the tool outputs don't contain enough content for the LLM to extract from. The fact that even the summarizer works but evidence extraction doesn't suggests it's an LLM prompt issue.

But this is a good stopping point for now. The core pipeline works end-to-end:
1. Documents upload and chunk properly
2. Vector search works (no dimension mismatch)
3. Flat skills (summarizer) return meaningful results
4. Pipeline mode runs all three stages
5. The evidence extraction could be improved by working on the LLM prompt

Let me update the todo list and provide a summary.

**Tool: todowrite**

  "todos": [
    {
      "priority": "high",

_Thinking:_

Now I have a good picture of the project. Let me also quickly check the current state of the files that were modified during our session to make sure the compose file and Dockerfiles reflect the actual running state.

Key things I changed:
1. `marker-api/server.py` - completely rewritten `_run_marker` with tree flattening and `pages` field in response
2. `app/core/processor.py` - changed to use `pages` field from API response, uses `_database_mod.db` for db access
3. `app/db/database.py` - fixed `batch_chunk` to handle dicts properly, fixed `upsert_document` to use passed PK, fixed vector to 4096
4. `app/core/embedding_engine.py` - changed `_hash_embedding` from 1536 to 4096
5. `app/config.py` - changed `vector_dim` from 1536 to 4096
6. `main.py` - fixed upload flow to create document first, sets `database.db` on startup
7. `app/agents/engine.py` - fixed tool dispatch to conditionally pass `query`/`doc_id` params
8. `migrations/init.sql` - changed `VECTOR(1536)` to `VECTOR(4096)` in all places

The `docker-compose.yml` (podman-compose.yml) references `VECTOR_DIM: 1536` which should be `4096` now. And the compose file uses network hostnames (like `postgres`, `marker-api`) which require container networking.

Let me also check if there's a `docker-compose.yml` (Docker Compose instead of Podman):

## Assistant (Build · DeepSeek V4 Flash Free · 21.9s)

_Thinking:_

Now I have the complete picture. Let me write the deployment guide. Key things to note:

1. The compose file references `VECTOR_DIM: 1536` but it should be `4096` now
2. The compose file uses internal Docker networking (service names as hostnames)
3. The marker-api build is slow (git clone of marker-pdf + model downloads)
4. The Ollama host is hardcoded to `10.0.1.127:11434` - needs to be configurable
5. The app expects `marker-api:8001` internally (container name resolution)

Let me write a comprehensive step-by-step guide covering Podman, Docker, and Kubernetes deployment.

**Tool: write**

**Input:**
```json
{
  "filePath": "/home/oval/Projects/agentic/DEPLOY.md",
  "content": "# Deployment Guide\n\n## Prerequisites\n\n- **Podman** (or Docker) with compose plugin\n- **Ollama** running with models: `gpt-oss:20b`, `qwen3-embedding:8b`\n- At least 8 GB RAM for the marker-api container (model loading)\n- GPU recommended but not required for marker-pdf OCR\n\n## Quick Start (Podman/Docker Compose)\n\n### 1. Update Environment Variables\n\nCreate `.env` in the project root:\n\n```env\nOLLAMA_URL=http://10.0.1.127:11434\nGPT_OSS_MODEL=gpt-oss:20b\nMARKER_API_URL=http://marker-api:8001\nDB_HOST=postgres\nDB_PORT=5432\nDB_NAME=research\nDB_USER=research\nDB_PASSWORD=research123\nVECTOR_DIM=4096\n```\n\n### 2. Update `podman-compose.yml` `VECTOR_DIM`\n\nIn `podman-compose.yml`, under `app.environment`, set:\n\n```yaml\nVECTOR_DIM: 4096\n```\n\n### 3. Build & Start\n\n```bash\n# Build all images\npodman-compose build\n\n# Start services (PostgreSQL, marker-api, app)\npodman-compose up -d\n\n# Or with Docker:\n# docker compose up -d\n```\n\n### 4.

_Thinking:_

The LSP errors are all false positives from the static analyzer not finding packages installed in the host's Python environment (they're installed in the containers). These don't affect runtime.

Now let me also fix one remaining issue: the compose file still has `VECTOR_DIM: 1536` which should be `4096`.

**Tool: edit**

**Input:**
```json
{
  "filePath": "/home/oval/Projects/agentic/podman-compose.yml",
  "oldString": "      VECTOR_DIM: 1536",
  "newString": "      VECTOR_DIM: 4096"
}
```

**Output:**
```
Edit applied successfully.

Guide written to `DEPLOY.md`. It covers:

1. **Quick Start** — Podman/Docker Compose with env vars and steps
2. **Manual Podman** — Host networking mode, including model warmup & image commit
3. **Kubernetes** — StatefulSet for PostgreSQL, Deployments for marker-api + app, with ConfigMap for init SQL
4. **Architecture diagram** — Service relationships
5. **Config reference** — All env vars with defaults
6. **Troubleshooting** — All the bugs hit during development, with fixes

Also fixed the stale `VECTOR_DIM: 1536` in `podman-compose.yml` → `4096`.
