# Dev Debug Toolbar + Centralized Logging Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Add `fastapi-debug-toolbar` (gated by `DEBUG=1`) with a custom DuckDBPanel, and replace 23 scattered `logging.basicConfig` calls with a single centralized `setup_logging()` helper that uses `RichHandler` in dev and JSON in prod.

**Architecture:** Phase 1–4 introduce `app/logging_config.py` and migrate every entrypoint (services, scripts, app, connectors) to call `setup_logging(__name__)`. Phase 5 mounts `DebugToolbarMiddleware` behind a `DEBUG=1` env gate so production never imports the toolbar. Phase 6 adds a custom `DuckDBPanel` with an `InstrumentedConnection` wrapper that hooks `src/db.py`'s three `duckdb.connect()` call sites. Phase 7 documents the `DEBUG=1` flag in `.env.template`, `CHANGELOG.md`, and `docs/development.md`.

**Tech Stack:** Python 3.11+, FastAPI, Starlette, DuckDB, `rich>=13` (already a dep), `fastapi-debug-toolbar>=0.6.3` (new dev-only dep, pulls Jinja2 + pyinstrument), pytest with coverage.

**Working directory for execution:** `/Users/vrysanek/foundry-ai/agnes-the-ai-analyst/.worktrees/main-dev-logging/` on branch `vr/dev-logging` (tracks `origin/main`). All paths below are relative to this worktree root.

### Discovered facts (verified during plan writing)

- `src/db.py` has three `duckdb.connect()` call sites: lines 413, 423, 581/587. Three public helpers: `get_system_db()` (line 394, returns `_system_db_conn.cursor()`), `get_analytics_db()` (line 419), `get_analytics_db_readonly()` (line 573).
- `services/scheduler/__main__.py:31`, `services/verification_detector/__main__.py:49`, `services/corporate_memory/collector.py:52`, `services/session_collector/collector.py:36`, `services/telegram_bot/bot.py:55`, `services/ws_gateway/gateway.py:214` — all have multi-line `basicConfig` calls.
- `app/api/sync.py:105` has a **module-level** `basicConfig` inside an api file — bug, will be removed (root logger is configured by the app entrypoint).
- 23 total `basicConfig` call sites enumerated.

## Task 1: Centralized logging module (`app/logging_config.py`) — Phase P1

**Files:**

## Task 2: Request-ID middleware (`app/middleware/request_id.py`) — Phase P2

**Files:**
- Create: `app/middleware/__init__.py` (empty)
- Create: `app/middleware/request_id.py`
- Test: `tests/test_request_id_middleware.py`

- [ ] **Step 2.1: Create empty package marker**

```bash
mkdir -p app/middleware
: > app/middleware/__init__.py
```

- [ ] **Step 2.2: Write the failing tests**

Create `tests/test_request_id_middleware.py`:

```python
import re

from fastapi import FastAPI
from fastapi.testclient import TestClient

from app.logging_config import request_id_var
from app.middleware.request_id import RequestIdMiddleware


def _make_app() -> FastAPI:
    app = FastAPI()
    app.add_middleware(RequestIdMiddleware)

    @app.get("/echo-rid")
    def echo_rid():
        return {"rid": request_id_var.get()}

    return app


def test_assigns_id_when_missing():
    client = TestClient(_make_app())
    resp = client.get("/echo-rid")
    assert resp.status_code == 200
    rid = resp.headers["x-request-id"]
    assert re.fullmatch(r"[0-9a-f]{12}", rid)
    assert resp.json()["rid"] == rid


def test_passes_through_provided_id():

    assert resp.status_code == 200
    assert resp.headers["x-request-id"] == "given-1234"
    assert resp.json()["rid"] == "given-1234"


def test_request_id_resets_after_request():
    client = TestClient(_make_app())
    client.get("/echo-rid")
    assert request_id_var.get() is None
```

- [ ] **Step 2.3: Run tests, verify they fail**

```bash
uv run pytest tests/test_request_id_middleware.py -q
```

Expected: `ModuleNotFoundError: No module named 'app.middleware.request_id'`.

- [ ] **Step 2.4: Implement the middleware**

Create `app/middleware/request_id.py`:

```python
"""Request-ID middleware. Assigns or propagates X-Request-ID per request."""

from __future__ import annotations

import uuid

from starlette.middleware.base import BaseHTTPMiddleware
from starlette.requests import Request
from starlette.responses import Response

from app.logging_config import request_id_var


class RequestIdMiddleware(BaseHTTPMiddleware):
    async def dispatch(self, request: Request, call_next) -> Response:

            request_id_var.reset(token)
        response.headers["x-request-id"] = rid
        return response
```

- [ ] **Step 2.5: Run tests, verify they pass**

```bash
uv run pytest tests/test_request_id_middleware.py -q
```

Expected: all 3 tests pass.

- [ ] **Step 2.6: Run quality checks**

```bash
ruff format app/middleware/ tests/test_request_id_middleware.py
ruff check app/middleware/ tests/test_request_id_middleware.py --fix
```

- [ ] **Step 2.7: Commit**

```bash
git add app/middleware/ tests/test_request_id_middleware.py
git commit -m "feat(http): add RequestIdMiddleware for cross-log correlation"
```

## Task 3: Wire `setup_logging` + `RequestIdMiddleware` into `app/main.py` — Phase P2 (continued)

**Files:**
- Modify: `app/main.py` (add `setup_logging` call at top of module before any other import that emits logs; add `RequestIdMiddleware`)
- Modify: `app/api/sync.py:105` (delete rogue `basicConfig`)

- [ ] **Step 3.1: Read `app/main.py` to find safe insertion points**

```bash
sed -n '1,40p' app/main.py
```

Expected: shows imports + module-level setup. Note the line where `app = FastAPI(...)` is created and where `app.include_router(...)` calls begin.

- [ ] **Step 3.2: Add `setup_logging("app")` near the top of `app/main.py`**

Locate the **first non-`from __future__` import** in `app/main.py`. Above the FastAPI import, add:

```python
from app.logging_config import setup_logging

setup_logging("app")
```

Keep it before any module that emits logs at import time.

- [ ] **Step 3.3: Mount `RequestIdMiddleware` immediately after `app = FastAPI(...)` is created**

Find the `app = FastAPI(...)` line. Immediately after it (before any `app.add_middleware(...)` or `app.include_router(...)`), add:

```python
from app.middleware.request_id import RequestIdMiddleware

app.add_middleware(RequestIdMiddleware)
```

- [ ] **Step 3.4: Delete rogue module-level `basicConfig` in `app/api/sync.py`**

Read `app/api/sync.py` lines 100–110 to find the exact line and any logger usage:

```bash
sed -n '100,115p' app/api/sync.py
```

Then delete the line:

```python
logging.basicConfig(level=logging.INFO, format="%(levelname)s: %(message)s")
```

If there is no other `import logging` usage in the file beyond this and a `logger = logging.getLogger(__name__)`, leave the import alone (the logger reference still needs it).

- [ ] **Step 3.5: Run the full test suite**

```bash
uv run pytest -q
```

Expected: all tests still pass. If any test was relying on the rogue `basicConfig` formatter from `sync.py`, it will surface here — fix by switching that test's expectations to use `caplog`.

- [ ] **Step 3.6: Sanity-check the app starts**

```bash
uv run uvicorn app.main:app --port 8011 &
APP_PID=$!
sleep 3
curl -s -i http://localhost:8011/health 2>/dev/null | head -10
kill $APP_PID
```

Expected: response includes `x-request-id: <12 hex chars>` header.

- [ ] **Step 3.7: Commit**

```bash
git add app/main.py app/api/sync.py
git commit -m "feat(app): wire setup_logging + RequestIdMiddleware in app/main.py"
```

---

## Task 4: Migrate service entrypoints — Phase P3

Six service entrypoints currently call `logging.basicConfig(...)` at module top level. Replace each with `setup_logging(__name__)`.

**Files:**
- Modify: `services/scheduler/__main__.py`
- Modify: `services/ws_gateway/gateway.py`
- Modify: `services/telegram_bot/bot.py`
- Modify: `services/corporate_memory/collector.py`
- Modify: `services/session_collector/collector.py`
- Modify: `services/verification_detector/__main__.py`

- [ ] **Step 4.1: Migrate `services/scheduler/__main__.py`**

Line 31 onward currently is:

```python
logging.basicConfig(
    level=os.environ.get("LOG_LEVEL", "INFO").upper(),
    format="%(asctime)s %(levelname)s [scheduler] %(message)s",
)
logger = logging.getLogger(__name__)
```

Replace the `logging.basicConfig(...)` block (multi-line) with:

```python
from app.logging_config import setup_logging

setup_logging(__name__)
logger = logging.getLogger(__name__)
```

Keep the existing `import logging` and the `logger = ...` line. Remove `import os` only if it is unused after the change (verify by running ruff after).

- [ ] **Step 4.2: Migrate `services/ws_gateway/gateway.py`**

Find the `logging.basicConfig(...)` block at line 214 (inside an `if __name__ == "__main__":` or similar startup function). Replace:

```python
logging.basicConfig(
    level=logging.INFO,
    format="%(asctime)s [%(levelname)s] %(name)s: %(message)s",
)
```

with:

```python
from app.logging_config import setup_logging
setup_logging(__name__)
```

- [ ] **Step 4.3: Migrate `services/telegram_bot/bot.py`**

Find the multi-line `logging.basicConfig(...)` block at line 55. Replace the entire block with:

```python
from app.logging_config import setup_logging
setup_logging(__name__)
logger = logging.getLogger("notify-bot")  # keep existing logger name to preserve log filters
```

Preserve any pre-existing custom logger name.

- [ ] **Step 4.4: Migrate `services/corporate_memory/collector.py`**

Find the multi-line `logging.basicConfig(...)` block at line 52. Replace with:

```python
from app.logging_config import setup_logging
setup_logging(__name__)
```

Keep any subsequent `logger = logging.getLogger(...)` line.

- [ ] **Step 4.5: Migrate `services/session_collector/collector.py`**

Find the multi-line `logging.basicConfig(...)` block at line 36. Replace with:

```python
from app.logging_config import setup_logging
setup_logging(__name__)
```

- [ ] **Step 4.6: Migrate `services/verification_detector/__main__.py`**

Find the multi-line `logging.basicConfig(...)` block at line 49 (inside the `__main__` function, NOT module-level). Replace inline:

```python
from app.logging_config import setup_logging
setup_logging(__name__)
```

- [ ] **Step 4.7: Run the full test suite**

```bash
uv run pytest -q
```

Expected: all tests pass. Service modules' tests (if any) may need `monkeypatch.setattr("app.logging_config._CONFIGURED", False)` to reset state.

- [ ] **Step 4.8: Smoke-test each service starts**

```bash
# Scheduler should start, log a single line, then idle
timeout 3 uv run python -m services.scheduler 2>&1 | head -5 || true
# Ws gateway should start
timeout 3 uv run python -m services.ws_gateway 2>&1 | head -5 || true
```

Expected: each service emits a startup log line in JSON (no `DEBUG=1`) or rich color (`DEBUG=1 timeout 3 uv run …`).

- [ ] **Step 4.9: Run quality checks**

```bash
ruff format services/
ruff check services/ --fix
```

- [ ] **Step 4.10: Commit**

```bash
git add services/
git commit -m "refactor(services): migrate entrypoints to centralized setup_logging"
```

## Task 5: Migrate `connectors/`, `src/`, `scripts/` — Phase P4

These 14 files have module-level or `__main__`-block `basicConfig` calls. The migration rules differ by location:

- **Module-level `basicConfig` in a library file** (e.g. `connectors/jira/transform.py`): just **remove** it — library modules should never configure root logger; the entrypoint that imports them is responsible.
- **`basicConfig` inside `if __name__ == "__main__":` block**: **replace** with `setup_logging(__name__)`.

**Files:**
- Modify: `src/catalog_export.py`, `src/profiler.py`
- Modify: `connectors/keboola/extractor.py`
- Modify: `connectors/jira/transform.py`, `incremental_transform.py`, `extract_init.py`
- Modify: `connectors/jira/scripts/poll_sla.py`, `backfill.py`, `backfill_sla.py`, `backfill_remote_links.py`, `consistency_check.py`
- Modify: `scripts/migrate_json_to_duckdb.py`, `migrate_metrics_to_duckdb.py`, `migrate_parquets_to_extracts.py`, `migrate_registry_to_duckdb.py`, `generate_sample_data.py`

- [ ] **Step 5.1: Determine library vs entrypoint per file**

For each file, run:

```bash
grep -nE 'if __name__ == "__main__"|basicConfig' <file>
```

If `basicConfig` is **outside** any `if __name__` block AND the file is imported by other modules → it is a library file. Remove the `basicConfig` line entirely.

If `basicConfig` is **inside** `if __name__ == "__main__"` OR the file is exclusively run as a script (the `scripts/` dir, `connectors/jira/scripts/`) → replace with `setup_logging(__name__)`.

| File | Verdict | Action |
|------|---------|--------|
| `src/catalog_export.py` | library + has `if __name__` block | check: if `basicConfig` is inside `__main__`, replace; else remove |
| `src/profiler.py` | library | remove |
| `connectors/keboola/extractor.py:289` | library, has CLI block at bottom | the `_logging.basicConfig` is inside the CLI block — replace with `setup_logging(__name__)` |
| `connectors/jira/transform.py:20` | library | **remove** (module-level) |
| `connectors/jira/incremental_transform.py:38` | library | **remove** (module-level) |
| `connectors/jira/extract_init.py:124` | inside `if __name__ == "__main__"` | replace |
| `connectors/jira/scripts/*.py` (5 files) | scripts | replace |
| `scripts/migrate_*.py` (4 files) | scripts | replace |
| `scripts/generate_sample_data.py:1035` | inside `if __name__ == "__main__"` | replace |

- [ ] **Step 5.2: Apply removals (library files)**

For each library file with module-level `basicConfig`:

`connectors/jira/transform.py:20`:
- delete the line `logging.basicConfig(level=logging.INFO)`.

`connectors/jira/incremental_transform.py:38`:
- delete the line `logging.basicConfig(level=logging.INFO)`.

`src/profiler.py:28`:
- delete the multi-line `logging.basicConfig(...)` call.

`src/catalog_export.py:43`:
- inspect: if outside any `__main__` block, delete the multi-line `basicConfig`; if inside, do step 5.3 instead.

```bash
sed -n '40,55p' src/catalog_export.py
sed -n '25,35p' src/profiler.py
```

- [ ] **Step 5.3: Apply replacements (entrypoint files)**

For each entrypoint file, replace the `basicConfig(...)` block with:

```python
from app.logging_config import setup_logging
setup_logging(__name__)
```

Files: `connectors/keboola/extractor.py:289` (note: uses `_logging` alias — replace the call inside the same scope), `connectors/jira/extract_init.py:124`, all 5 `connectors/jira/scripts/*.py`, all 4 `scripts/migrate_*.py`, `scripts/generate_sample_data.py:1035`.

For `connectors/keboola/extractor.py`:
```python
# was:
#     _logging.basicConfig(level=_logging.INFO, format="%(levelname)s: %(message)s")
from app.logging_config import setup_logging
setup_logging(__name__)
```

- [ ] **Step 5.4: Verify no `basicConfig` left in production code**

```bash
grep -rEn 'logging\.basicConfig|_logging\.basicConfig' \
    src/ app/ services/ connectors/ scripts/ \
    --include="*.py" | grep -v "tests/" || echo "CLEAN"
```

Expected: prints `CLEAN`. If anything matches, decide library vs entrypoint and fix.

- [ ] **Step 5.5: Run the full test suite**

```bash
uv run pytest -q
```

Expected: all tests pass.

- [ ] **Step 5.6: Smoke-test one CLI script**

```bash
DATA_DIR=/tmp/agnes-smoke uv run python -m scripts.migrate_metrics_to_duckdb --help 2>&1 | head -10 || true
```

Expected: usage message appears with no double-config warnings.

- [ ] **Step 5.7: Run quality checks**

```bash
ruff format src/ connectors/ scripts/
ruff check src/ connectors/ scripts/ --fix
```

- [ ] **Step 5.8: Commit**

```bash
git add src/ connectors/ scripts/
git commit -m "refactor(logging): remove scattered basicConfig calls across libs and scripts"
```

## Task 6: Add `fastapi-debug-toolbar` dev dep + wire middleware behind `DEBUG=1` — Phase P5

**Files:**
- Modify: `pyproject.toml` (add dev dep)
- Modify: `app/main.py` (mount `DebugToolbarMiddleware` only if `DEBUG=1`)

- [ ] **Step 6.1: Add the dev dependency**

Edit `pyproject.toml` `[project.optional-dependencies].dev` block:

```toml
[project.optional-dependencies]
dev = [
    "pytest>=9.0.0",
    "pytest-timeout>=2.0.0",
    "pytest-xdist>=3.0.0",
    "faker>=24.0.0",
    "anthropic>=0.30.0",
    "openai>=1.30.0",
    "jsonschema>=4.0.0",
    "fastapi-debug-toolbar>=0.6.3",
]
```

Also mirror under `[tool.uv].dev-dependencies` if present:

```toml
[tool.uv]
dev-dependencies = [
    "pytest>=9.0.0",
    "pytest-timeout>=2.0.0",
    "pytest-xdist>=3.0.0",
    "faker>=24.0.0",
    "anthropic>=0.30.0",
    "openai>=1.30.0",
    "fastapi-debug-toolbar>=0.6.3",
]
```

- [ ] **Step 6.2: Install the new dep**

```bash
uv pip install ".[dev]"
```

Expected: installs `fastapi-debug-toolbar`, `Jinja2` (already a dep), `pyinstrument`.

- [ ] **Step 6.3: Wire `DebugToolbarMiddleware` in `app/main.py`**

Locate the `app.add_middleware(RequestIdMiddleware)` line added in Task 3. Immediately after it, add:

```python
import os

DEBUG = os.environ.get("DEBUG", "").lower() in ("1", "true", "yes")

if DEBUG:
    try:
        from debug_toolbar.middleware import DebugToolbarMiddleware
        app.add_middleware(
            DebugToolbarMiddleware,
            panels=[
                "debug_toolbar.panels.headers.HeadersPanel",
                "debug_toolbar.panels.routes.RoutesPanel",
                "debug_toolbar.panels.settings.SettingsPanel",
                "debug_toolbar.panels.versions.VersionsPanel",
                "debug_toolbar.panels.timer.TimerPanel",
                "debug_toolbar.panels.logging.LoggingPanel",
                "debug_toolbar.panels.profiling.ProfilingPanel",
            ],
            settings={"REFRESH_INTERVAL": 5000},
        )
    except ImportError:
        import logging
        logging.getLogger(__name__).warning(
            "DEBUG=1 but fastapi-debug-toolbar not installed; toolbar disabled"
        )
```

The `DuckDBPanel` is added in Task 8, not here.

Also adjust the `app = FastAPI(...)` call to honor `DEBUG`:

```python
app = FastAPI(debug=DEBUG, ...existing kwargs...)
```

- [ ] **Step 6.4: Manual browser verification**

```bash
DEBUG=1 uv run uvicorn app.main:app --port 8011 &
APP_PID=$!
sleep 3
```

Use `playwright-cli` for verification (per `browser-automation.md`):

```bash
playwright-cli -s=$PILOT_SESSION_ID open http://localhost:8011/dashboard
playwright-cli -s=$PILOT_SESSION_ID snapshot
# Expect to see a "djdt" or toolbar tab in the accessibility tree
playwright-cli -s=$PILOT_SESSION_ID screenshot /tmp/toolbar.png
playwright-cli -s=$PILOT_SESSION_ID close

kill $APP_PID
```

Expected: screenshot shows toolbar tab on right edge of the page. If the route requires auth, set `LOCAL_DEV_MODE=1` too.

If you don't have playwright-cli, use this curl + grep verification:

```bash
DEBUG=1 uv run uvicorn app.main:app --port 8011 &
APP_PID=$!
sleep 3
LOCAL_DEV_MODE=1 curl -s http://localhost:8011/dashboard 2>/dev/null | grep -i "fastDebug\|debug.*toolbar" | head -3
kill $APP_PID
```

Expected: at least one match showing the toolbar HTML was injected.

- [ ] **Step 6.5: Verify toolbar is OFF without DEBUG**

```bash
uv run uvicorn app.main:app --port 8011 &
APP_PID=$!
sleep 3
curl -s http://localhost:8011/dashboard 2>/dev/null | grep -ci "fastDebug" || echo "no toolbar (correct)"
kill $APP_PID
```

Expected: `no toolbar (correct)`.

- [ ] **Step 6.6: Verify under `docker compose up`**

Compose runs uvicorn under a non-TTY stdout, which is the case `force_terminal=True` exists for. This step catches docker-only failure modes that uvicorn-direct misses (env propagation, log multiplexing).

```bash
DEBUG=1 LOCAL_DEV_MODE=1 docker compose up -d app
sleep 8
docker compose logs --tail=30 app | grep -iE "rich|debug|toolbar|color" || true
docker compose exec -T app sh -lc 'python -c "import os; print(\"DEBUG=\", os.environ.get(\"DEBUG\"))"'
curl -s http://localhost:8000/health -i 2>/dev/null | head -5
docker compose down
```

Expected:
- Compose log lines appear with ANSI color codes (e.g. `\e[`) — proves `force_terminal=True` is doing its job.
- The python eval prints `DEBUG= 1`.
- `/health` returns 200 with `x-request-id` header.

If colors are missing, `force_terminal=True` is being overridden — check whether the compose service has `tty: true` set, or whether stdout is being piped through a process that strips ANSI.

- [ ] **Step 6.7: Run the full test suite**

```bash
uv run pytest -q
```

Expected: all tests pass.

- [ ] **Step 6.8: Commit**

```bash
git add pyproject.toml app/main.py uv.lock
git commit -m "feat(dev): mount fastapi-debug-toolbar behind DEBUG=1"
```

## Task 7: `InstrumentedConnection` — Phase P6 (part 1)

**Files:**
- Create: `app/debug/__init__.py` (empty)
- Create: `app/debug/duckdb_panel.py` (just `InstrumentedConnection` and helpers — `DuckDBPanel` itself comes in Task 8)
- Test: `tests/test_duckdb_panel.py`

- [ ] **Step 7.1: Create empty package marker**

```bash
mkdir -p app/debug/templates/panels
: > app/debug/__init__.py
```

- [ ] **Step 7.2: Write the failing tests**

Create `tests/test_duckdb_panel.py`:

```

- [ ] **Step 7.3: Run tests, verify they fail**

```bash
uv run pytest tests/test_duckdb_panel.py -q
```

Expected: `ImportError: cannot import name 'InstrumentedConnection'`.

- [ ] **Step 7.4: Implement `InstrumentedConnection` and helpers**

Create `app/debug/duckdb_panel.py` (panel class will be added in Task 8):

```python
"""Per-request DuckDB query capture for the dev debug toolbar.

`InstrumentedConnection` wraps a `duckdb.DuckDBPyConnection` and records
every `.execute()` call into a contextvar-scoped store. The toolbar's
`DuckDBPanel` reads that store at response time.

When the contextvar is unset (outside a debug request, or in prod), all
recording is a no-op — `_maybe_instrument()` in `src/db.py` returns the
raw connection, so the wrapper isn't even constructed in prod paths.

## Task 8: `DuckDBPanel` + Jinja template + integration in `src/db.py` — Phase P6 (part 2)

**Files:**
- Modify: `app/debug/duckdb_panel.py` (append `DuckDBPanel` class)
- Create: `app/debug/templates/panels/duckdb.html`
- Modify: `src/db.py` (add `_maybe_instrument`; wrap returns)
- Modify: `app/main.py` (add `app.debug.duckdb_panel.DuckDBPanel` to the panels list)
- Test: `tests/test_toolbar_integration.py`

- [ ] **Step 8.1: Append `DuckDBPanel` to `app/debug/duckdb_panel.py`**

Add at the bottom of the file:

```python

- [ ] **Step 8.3: Wrap connections in `src/db.py`**

The file has three `duckdb.connect()` call sites: lines 413, 423, 581, 587. The three public helpers return:
- `get_system_db()` — returns `_system_db_conn.cursor()` (line 416). Wrap the cursor.
- `get_analytics_db()` — returns the connection directly (line 423). Wrap it.
- `get_analytics_db_readonly()` — two return paths (lines 586, 587 onward). Wrap both.

Add this helper near the top of `src/db.py` (just after the imports):

```python
import os as _os_for_debug

_DEBUG = _os_for_debug.environ.get("DEBUG", "").lower() in ("1", "true", "yes")


def _maybe_instrument(con, db_tag: str):
    """Wrap a duckdb connection with InstrumentedConnection when DEBUG=1, else return as-is."""
    if not _DEBUG:
        return con
    from app.debug.duckdb_panel import InstrumentedConnection
    return InstrumentedConnection(con, db_tag)
```

Then modify each helper:

**`get_system_db()`** at line 394 — the `return _system_db_conn.cursor()` becomes:

```python
return _maybe_instrument(_system_db_conn.cursor(), "system")
```

**`get_analytics_db()`** at line 419 — the `return duckdb.connect(str(db_path))` becomes:

```python
return _maybe_instrument(duckdb.connect(str(db_path)), "analytics")
```

**`get_analytics_db_readonly()`** at line 573 — both return statements (line 586 with `return conn` and line 587 with `conn = duckdb.connect(str(db_path), read_only=True)` followed by ATTACH + final `return conn`) get the wrap applied at the **final** return only:

The function ends with something like `return conn` after ATTACH loop. Replace that final `return conn` with `return _maybe_instrument(conn, "analytics_ro")`.

For the early-return path (lines 581–586) where the file doesn't exist: replace the early `return conn` with `return _maybe_instrument(conn, "analytics_ro")`.

```bash
sed -n '580,605p' src/db.py  # verify exact return sites before editing
```

- [ ] **Step 8.4: Mount `DuckDBPanel` in `app/main.py`**

Edit the panel list created in Task 6.3. Add the DuckDBPanel string to the list:

```python
panels=[
    "debug_toolbar.panels.headers.HeadersPanel",
    "debug_toolbar.panels.routes.RoutesPanel",
    "debug_toolbar.panels.settings.SettingsPanel",
    "debug_toolbar.panels.versions.VersionsPanel",
    "debug_toolbar.panels.timer.TimerPanel",
    "debug_toolbar.panels.logging.LoggingPanel",
    "debug_toolbar.panels.profiling.ProfilingPanel",
    "app.debug.duckdb_panel.DuckDBPanel",
],
```

The toolbar resolves panels by import string. Confirm `app/debug/duckdb_panel.py` exposes `DuckDBPanel` at module level (it does — see Step 8.1).

- [ ] **Step 8.5: Configure Jinja template lookup**

The toolbar needs to find `panels/duckdb.html`. Wire the template path by adding a conftest-style env or by passing the path to the middleware via `settings`. The simplest path: copy/symlink the template into the toolbar's expected lookup. Verify by reading `fastapi-debug-toolbar` docs:

```bash
uv run python -c "import debug_toolbar.middleware as m; import inspect; print(inspect.getfile(m))"
```

Then check how panels with custom templates register lookup paths. If the toolbar uses Jinja `PackageLoader`, set `template = "panels/duckdb.html"` AND ensure `app/debug/templates/` is on its lookup path. The standard way (per upstream) is to set the `template` attribute and rely on the panel's own package; since `DuckDBPanel` lives in `app.debug.duckdb_panel`, the toolbar should resolve `app/debug/templates/panels/duckdb.html` automatically via package introspection.

If the toolbar fails to find the template, add this class attribute on `DuckDBPanel`:

```python
template_dirs = ["app/debug/templates"]
```

Verify by hitting an HTML route with `DEBUG=1` and inspecting the rendered toolbar HTML.

- [ ] **Step 8.6: Write the integration tests**

Create `tests/test_toolbar_integration.py`:

```python
import os

import pytest
from fastapi import FastAPI
from fastapi.testclient import TestClient


@pytest.fixture
def reset_logging_state():
    import app.logging_config as lc
    lc._CONFIGURED = False
    yield
    lc._CONFIGURED = False
    import logging
    logging.getLogger().handlers.clear()


@pytest.fixture
def app_with_toolbar(monkeypatch, reset_logging_state):
    monkeypatch.setenv("DEBUG", "1")
    # Reload app.main fresh so DEBUG gate is honored
    import importlib
    import app.main as main_mod
    importlib.reload(main_mod)
    return main_mod.app


@pytest.fixture
def app_no_toolbar(monkeypatch, reset_logging_state):
    monkeypatch.delenv("DEBUG", raising=False)
    import importlib
    import app.main as main_mod
    importlib.reload(main_mod)
    return main_mod.app


@pytest.mark.integration
def test_toolbar_html_present_when_debug(app_with_toolbar):
    client = TestClient(app_with_toolbar)
    # Hit any HTML response endpoint (the dashboard or login page)
    resp = client.get("/dashboard", follow_redirects=False)
    if resp.status_code in (302, 401):
        pytest.skip("Dashboard requires auth in this env; visual verify covered separately")
    assert resp.status_code == 200
    body = resp.text.lower()
    assert "djdt" in body or "fastdebug" in body, "Toolbar markup not injected"


@pytest.mark.integration
def test_no_toolbar_when_debug_off(app_no_toolbar):
    client = TestClient(app_no_toolbar)
    resp = client.get("/dashboard", follow_redirects=False)
    if resp.status_code in (302, 401):
        return
    body = resp.text.lower()
    assert "djdt" not in body
    assert "fastdebug" not in body


@pytest.mark.integration
def test_request_id_header_always_present(app_no_toolbar):
    client = TestClient(app_no_toolbar)
    resp = client.get("/health")
    assert "x-request-id" in resp.headers
```

- [ ] **Step 8.7: Run integration tests**

```bash
uv run pytest tests/test_toolbar_integration.py -q
```

Expected: tests pass (or skip when auth required). If `dashboard` is hidden behind login, test against another HTML route (`/login` or `/setup`) — adjust the fixture to a route known to render HTML without auth.

- [ ] **Step 8.8: Manual browser verification with playwright-cli**

```bash
DEBUG=1 LOCAL_DEV_MODE=1 uv run uvicorn app.main:app --port 8011 &
APP_PID=$!
sleep 4

playwright-cli -s=$PILOT_SESSION_ID open http://localhost:8011/admin/access
playwright-cli -s=$PILOT_SESSION_ID snapshot
playwright-cli -s=$PILOT_SESSION_ID screenshot /tmp/toolbar-duckdb.png
playwright-cli -s=$PILOT_SESSION_ID close

kill $APP_PID
ls -la /tmp/toolbar-duckdb.png
```

Open `/tmp/toolbar-duckdb.png` (or read with the Read tool — it accepts images). Confirm:
- Toolbar tab visible on right edge
- Clicking opens panels list including **DuckDB**
- DuckDB panel shows queries with `system` / `analytics_ro` tags

If toolbar tab not visible: check uvicorn logs for `fastapi-debug-toolbar not installed` warning or template-loader errors.

- [ ] **Step 8.9: Run the full test suite**

```bash
uv run pytest -q --cov=app.logging_config --cov=app.middleware --cov=app.debug --cov-fail-under=80
```

Expected: tests pass and coverage on the new modules ≥ 80%.

- [ ] **Step 8.10: Verify DuckDBPanel under `docker compose up`**

```bash
DEBUG=1 LOCAL_DEV_MODE=1 docker compose up -d app
sleep 8
# Trigger a request that hits the DB
curl -s http://localhost:8000/dashboard -o /tmp/dash.html
docker compose logs --tail=40 app | head -40
grep -i "duckdb\|djdt" /tmp/dash.html | head -5
docker compose down
```

Expected: `dash.html` contains the toolbar HTML with the DuckDB panel slot. Logs show DB queries when DEBUG=1 (debug-level log output captures execute calls indirectly through any `logger.debug` in src/db.py).

- [ ] **Step 8.11: Run quality checks**

```bash
ruff format app/ src/db.py tests/test_toolbar_integration.py
ruff check app/ src/db.py tests/test_toolbar_integration.py --fix
```

- [ ] **Step 8.12: Commit**

```bash
git add app/debug/ src/db.py app/main.py tests/test_toolbar_integration.py
git commit -m "feat(debug): add DuckDBPanel rendering per-request queries with db tag"
```

## Task 9: Documentation, `.env.template`, CHANGELOG — Phase P7

**Files:**
- Modify: `config/.env.template` (or `.env.template` at repo root — verify location)
- Create: `docs/development.md`
- Modify: `CHANGELOG.md`

- [ ] **Step 9.1: Locate the env template**

```bash
ls -la config/.env.template .env.template 2>/dev/null
```

The CLAUDE.md references `config/.env.template`. Verify path before editing.

- [ ] **Step 9.2: Document `DEBUG=1` in env template**

Append to `config/.env.template` (or wherever it lives):

```bash

# === Local development ===
# DEBUG=1 enables:
#   - FastAPI debug=True (richer 500 pages)
#   - rich.logging.RichHandler (colored, with tracebacks)
#   - fastapi-debug-toolbar mounted at right edge of HTML pages
#   - DuckDB query capture in the toolbar
# Never set in production. Keep separate from LOCAL_DEV_MODE (auth bypass).
# DEBUG=1
```

- [ ] **Step 9.3: Create developer docs**

Create `docs/development.md`:

```markdown
# Development guide

## Logging

All processes (FastAPI app, scheduler, telegram_bot, ws_gateway, corporate_memory,
session_collector, CLI scripts) use `app.logging_config.setup_logging` to configure
the root logger. Each entrypoint calls it once:

```python
from app.logging_config import setup_logging
setup_logging(__name__)
```

Library modules just do `logger = logging.getLogger(__name__)` — they never
configure root.

| Env | Handler | Format |
|-----|---------|--------|
| `DEBUG=1` | `rich.logging.RichHandler` | colored, clickable file:line, pretty tracebacks |
| (default) | stdlib `StreamHandler` | JSON to stderr (`ts`, `lvl`, `logger`, `service`, `msg`, optional `request_id`) |

`LOG_LEVEL` overrides the level (default `DEBUG` when `DEBUG=1`, else `INFO`).

## Request correlation

`RequestIdMiddleware` is mounted unconditionally on the FastAPI app. It assigns
or propagates `X-Request-ID` and exposes it via the `request_id_var`
ContextVar so the JSON formatter and the debug-toolbar logging panel see the
same id.

## Debug toolbar

Set `DEBUG=1` to mount `fastapi-debug-toolbar`. Visit any HTML page (e.g.
`/admin/access`, `/dashboard`, `/login`) and click the small toolbar tab on
the right edge.

Panels:

- **Headers** — request/response headers
- **Routes** — registered FastAPI routes
- **Settings** — Pydantic / instance-config values
- **Versions** — installed package versions
- **Timer** — request duration
- **Logging** — log records emitted during the request
- **Profiling** — `pyinstrument` flame graph
- **DuckDB** — every `con.execute(sql, params)` from `src/db.py`, tagged
  by `system` / `analytics` / `analytics_ro`, with timing and row count

JSON-only endpoints (Swagger UI at `/docs`) replay the most recent request's
panels via a cookie-based mechanism.

The toolbar is **never imported in production**: the import is gated by
`if DEBUG: ...` in `app/main.py`, and `fastapi-debug-toolbar` lives only in
the dev optional-dependency group.

## Running locally

```bash
uv pip install ".[dev]"
DEBUG=1 LOCAL_DEV_MODE=1 uv run uvicorn app.main:app --reload --port 8000
```

Open `http://localhost:8000/dashboard`.
```

- [ ] **Step 9.4: Update CHANGELOG.md**

Read the top of `CHANGELOG.md`:

```bash
sed -n '1,30p' CHANGELOG.md
```

If a `## [Unreleased]` heading exists at the top, add bullets under it. If not, create one above the topmost released version.

Add under `### Added`:

```markdown
## [Unreleased]

### Added
- Dev debug toolbar gated by `DEBUG=1`. Mounts `fastapi-debug-toolbar` with panels
  for headers, routes, settings, versions, timer, logging, profiling, and a custom
  DuckDB panel that captures every `con.execute()` from `src/db.py` (tagged by
  `system` / `analytics` / `analytics_ro`). See `docs/development.md`.
- `X-Request-ID` request header / response header on every FastAPI response, plus
  a `request_id` field in JSON logs for cross-process correlation.
- Centralized `app.logging_config.setup_logging()` — replaces 23 scattered
  `logging.basicConfig(...)` calls. Uses `rich.logging.RichHandler` in dev
  (`DEBUG=1`) and JSON to stderr in prod.

### Changed
- All service entrypoints (`services/scheduler/__main__.py`, `ws_gateway`,
  `telegram_bot`, `corporate_memory`, `session_collector`, `verification_detector`)
  and CLI scripts under `scripts/` and `connectors/jira/scripts/` now call
  `setup_logging(__name__)` instead of inline `basicConfig`. Library modules no
  longer configure root logger at import time.

### Fixed
- Removed rogue module-level `logging.basicConfig` from `app/api/sync.py` that
  was reconfiguring root logger every time the api module was imported.
```

- [ ] **Step 9.5: Run the full test suite one more time**

```bash
uv run pytest -q
```

Expected: all tests pass.

- [ ] **Step 9.6: Final verification**

Confirm no remaining `basicConfig` outside tests:

```bash
grep -rEn 'logging\.basicConfig|_logging\.basicConfig' \
    src/ app/ services/ connectors/ scripts/ \
    --include="*.py" | grep -v "tests/" || echo "CLEAN"
```

Expected: `CLEAN`.

Confirm `DEBUG=1` smoke test:

```bash
DEBUG=1 LOCAL_DEV_MODE=1 uv run uvicorn app.main:app --port 8011 &
APP_PID=$!
sleep 4
curl -s http://localhost:8011/health -i 2>/dev/null | head -5
kill $APP_PID
```

Expected: response with `x-request-id` header. Server log line is rich-colored.

- [ ] **Step 9.7: Commit**

```bash
git add config/.env.template docs/development.md CHANGELOG.md
git commit -m "docs: document DEBUG=1 toggle and centralized logging"
```

- [ ] **Step 9.8: Push branch**

```bash
git push -u origin vr/dev-logging
```

Open a PR via `gh pr create` (out of scope for this plan — the user runs PR creation separately).

## Self-Review Checklist (already applied during plan writing)

- [x] **Spec coverage:** every section in the spec maps to one of Tasks 1–9.
  - logging_config + RichHandler → Task 1
  - RequestIdMiddleware → Tasks 2–3
  - migration of 23 basicConfig calls → Tasks 3, 4, 5
  - DuckDBPanel + InstrumentedConnection → Tasks 7–8
  - production safeguards (DEBUG gate, dev-only dep) → Task 6
  - docs / CHANGELOG / .env.template → Task 9
- [x] **Placeholder scan:** no TBD, TODO, or "implement later" left in the plan.
- [x] **Type consistency:** `Query` dataclass used in tests and in `DuckDBPanel.generate_stats`; `InstrumentedConnection.cursor()` returns `InstrumentedConnection` (matches test).
- [x] **Files-not-to-modify rule:** plan does NOT touch `connectors/jira/file_lock.py`, `connectors/jira/transform.py` is library-level — only the `basicConfig` line is removed (plan respects "core logic" stability), `services/ws_gateway/` is touched only at the entrypoint `gateway.py:214` for the `basicConfig` swap (no logic change).
