-# Bug Investigation: Cadence Decrease Hot-Reload
-
-**Date:** 2026-05-16
-**Component:** central-supervisor
-**File:** `supervisor.py`
-
----
-
-## 1. Reproduction
-
-### Test Case: Decrease 60s → 30s
-```
-Tlast (poll completed): 04:18:24Z
-Config change applied:  04:18:30Z (approx)
-Expected next poll:     04:18:54Z (Tlast + 30s)
-Actual next poll:       04:19:24Z (Tlast + 60s - OLD cadence)
-Subsequent polls:       Also at 60s intervals
-```
-
-### Log Evidence
-```json
-{"ts": "...", "msg": "Rescheduled adapter", "adapter": "nws", "old_cadence_s": 60, "new_cadence_s": 30, "next_poll": "2026-05-16T04:18:54+00:00"}
-```
-- "Rescheduled adapter" log fires with **correct** calculated next_poll
-- Actual poll occurs at OLD cadence time
-- Subsequent polls continue at OLD cadence
-
-### Contrast: Increase 60s → 90s (WORKS)
-```
-Tlast:              03:16:34Z
-Config change:      03:16:36Z
-Expected next poll: 03:18:04Z (Tlast + 90s)
-Actual next poll:   03:18:04Z ✅
-```
-
----
-
-## 2. Root Cause
-
-### Location
-`supervisor.py` lines 395-450 (`_reschedule_adapter`) and lines 144-181 (`_run_adapter_loop`)
-
-### The Bug
-The `cancel_event.set()` call in `_reschedule_adapter` does not reliably wake the `asyncio.wait_for()` in the adapter loop when the cadence is **decreased**.
-
-### Why It Happens
-
-1. **Event handler holds lock during signal:**
-   ```python
-   # _on_config_change (line 466)
-   async with self._lock:
-       new_config = await self._config_source.get_adapter(adapter_name)
-       # ...
-       await self._reschedule_adapter(adapter_name, new_config)  # sets cancel_event here
-   ```
-
-2. **Reschedule updates config then signals:**
-   ```python
-   # _reschedule_adapter
-   state.config = new_config     # Line 420
-   state.adapter.cadence_s = new_cadence  # Line 423
-   # ... logging ...
-   state.cancel_event.set()      # Line 450 - inside lock context
-   ```
-
-3. **Asyncio event delivery delay:**
-   The `asyncio.Event.set()` queues a wakeup for waiting tasks, but the signal delivery is subject to asyncio's task scheduler. When called from within an `async with` block, the event may not be processed until the current task yields or the lock context exits.
-
-4. **Timing difference between increase and decrease:**
-   - **Increase (60→90):** Loop has ~30-50s remaining sleep. Event signal arrives well before timeout.
-   - **Decrease (90→60):** Loop may be ~10s from timeout. By the time event signal is processed, timeout has already fired.
-
-5. **Why subsequent polls use old cadence:**
-   When the loop times out naturally (rather than being woken by event), it proceeds to poll. After poll completes, `state.last_completed_poll` is updated. The loop then reads `state.config.cadence_s` for the NEXT iteration — but if `state.config` was somehow not durably updated (or there's a stale reference), it uses the old value.
-
-   **Alternative theory:** The `state.config = new_config` assignment creates a new config object, but the loop may be reading from a captured reference to the old object if there's any closure behavior we're not seeing.
-
----
-
-## 3. Proposed Fix
-
-### Option A: Force immediate reschedule (Recommended)
-
-Move the cancel logic OUTSIDE the lock, and use a more aggressive wake pattern:
-
-```python
-async def _reschedule_adapter(self, name: str, new_config: AdapterConfig) -> None:
-    state = self._adapter_states.get(name)
-    if state is None or not state.is_running:
-        await self._start_adapter(new_config)
-        return
-
-    old_cadence = state.config.cadence_s
-    new_cadence = new_config.cadence_s
-
-    # Update config atomically
-    state.config = new_config
-    state.adapter.cadence_s = new_cadence
-
-    # ... (NWS-specific updates, logging) ...
-
-    # Cancel and wait for acknowledgment
-    state.cancel_event.set()
-    await asyncio.sleep(0)  # Force task switch to process event
-```
-
-### Option B: Stop and restart the loop task
-
-For cadence changes, stop the current loop task and create a new one:
-
-```python
-async def _reschedule_adapter(self, name: str, new_config: AdapterConfig) -> None:
-    state = self._adapter_states.get(name)
-    if state is None:
-        await self._start_adapter(new_config)
-        return
-
-    # Preserve last_completed_poll
-    preserved_poll = state.last_completed_poll
-
-    # Stop current loop
-    await self._stop_adapter(name)
-
-    # Update config
-    state.config = new_config
-    state.last_completed_poll = preserved_poll
-
-    # Restart loop
-    await self._start_adapter(new_config)
-```
-
-### Option C: Double-signal pattern
-
-Set the event, yield, then set again to ensure delivery:
-
-```python
-state.cancel_event.set()
-await asyncio.sleep(0)
-state.cancel_event.set()  # Redundant but ensures visibility
-```
-
----
-
-## 4. Test Gap
-
-### Missing Tests
-
-The test file `test_config_source_new.py` only tests ConfigSource behavior (list, get, protocol compliance). There are **no tests** for:
-
-1. `_reschedule_adapter` interrupting a sleeping loop
-2. Cadence decrease being applied mid-sleep
-3. Cadence increase being applied mid-sleep
-4. Rate-limit guarantee after reschedule
-5. `cancel_event` mechanism in isolation
-
-### Recommended Tests
-
-```python
-@pytest.mark.asyncio
-async def test_cadence_decrease_applies_immediately():
-    """Cadence decrease should wake sleeping loop and reschedule."""
-    # Setup: Adapter polling at 60s cadence
-    # Action: Change cadence to 30s while sleeping
-    # Assert: Next poll at last_poll + 30s, not last_poll + 60s
-
-@pytest.mark.asyncio
-async def test_cadence_increase_applies_on_next_cycle():
-    """Cadence increase should wake sleeping loop and extend wait."""
-    # Setup: Adapter polling at 60s cadence
-    # Action: Change cadence to 90s while sleeping
-    # Assert: Next poll at last_poll + 90s
-
-@pytest.mark.asyncio
-async def test_cancel_event_wakes_sleeping_loop():
-    """cancel_event.set() should interrupt asyncio.wait_for()."""
-    # Unit test for the event mechanism in isolation
-```
-
----
-
-## 5. State at End
-
-### LXC State (Reverted)
-- **Cadence in DB:** 60s ✅
-- **Actual poll interval:** 60s ✅
-- **Supervisor restarted:** 2026-05-16T04:43:40Z
-- **Verified polls:**
-  ```
-  04:43:40.964 - First poll after restart
-  04:44:41.171 - Second poll (61s later) ✅
-  ```
-
-### Mitigation Until Fix
-After any cadence change (especially decrease), verify actual poll intervals. If incorrect, restart supervisor:
-```bash
-systemctl restart central-supervisor
-```
-

-
-### Interactive Map
-- Bbox selection via click-drag rectangle
-- Same UI component for all adapters (NWS, FIRMS, USGS)
-- Stores `{north, south, east, west}` floats
-- Preview of coverage area with state/country boundaries

-- Common presets: CONUS, Pacific Northwest, Mountain West
-- Quick-select buttons alongside custom draw

-## Phase B Step 2: Config Source Cutover (TOML → DB)
-
-**Timestamp:** 2026-05-16T03:13:33Z
-
-### Environment Change
-```
-# /etc/central/central.env - added:
-CENTRAL_CONFIG_SOURCE=db
-```
-
-### Supervisor Journal Evidence

----
-
-## Phase B Step 3: Hot-Reload Cadence Test
-
-**Test:** Change cadence from 60s → 90s while adapter is running.
-**Goal:** Verify next poll is at Tlast + new_cadence (not old cadence, not immediate).
-
-### Timeline
-```
-Tlast (last poll):     03:16:34.317219Z

-
----
-
-## Phase B Step 4: Hot-Reload Enable/Disable Test
-
-**Test:** Disable adapter, wait, re-enable.
-**Goal:** Verify next poll is at Tlast + cadence (not immediate on re-enable).
-
-### Timeline
-```

-## Cadence Revert (Close-out)
-
-**Timestamp:** 2026-05-16T03:54:14Z
-
-### Issue Discovered
-
-During close-out verification, polls were observed at 90s intervals despite
-DB showing `cadence_s = 60`. Investigation revealed the live reschedule
-from 90→60 (done at 03:23:08 during Phase B) didn't properly update the
-in-flight scheduling.
-
-### Resolution
-
-Supervisor restart was required to clear stale state:
-
-```bash
-systemctl restart central-supervisor
-```
-
-### Post-Restart Verification
-
-**DB State:**
-```sql
-SELECT name, cadence_s, updated_at FROM config.adapters WHERE name='nws';
-```
-```
- name | cadence_s |          updated_at
-------+-----------+-------------------------------
- nws  |        60 | 2026-05-16 03:50:53.210963+00
-```
-
-**Poll Intervals After Restart:**
-```
-03:54:14.621376 - NWS poll completed (first poll after restart)
-03:55:15.028963 - NWS poll completed (61s later) ✅
-03:56:15.429013 - NWS poll completed (60s later) ✅
-```
-
-**Startup Log:**
-```json
-{"ts": "2026-05-16T03:54:14.318479+00:00", "msg": "Adapter started", "adapter": "nws", "cadence_s": 60}
-```
-
-### Bug Note
-
-The cadence DECREASE (90→60) rate-limit test from Phase B showed correct
-log output ("Rescheduled adapter" with new_cadence_s=60) but the actual
-scheduling didn't update properly. The increase test (60→90) worked
-correctly.
-
-**Root cause:** Unknown - requires investigation. The `_reschedule_adapter`
-method updates `state.config` and `state.adapter.cadence_s`, and signals
-via `cancel_event`, but the scheduling loop may not be re-evaluating
-correctly for decreases.
-
-**Mitigation:** After any cadence change, verify actual poll intervals match
-expected cadence. If not, restart supervisor.
-
-**Result:** Cadence confirmed at 60s after restart. ✅

-## Final Cadence-Decrease Fix Verification
-
-**Date:** 2026-05-16T17:19-17:25 UTC
-**Branch:** feature/remove-adapter-limiter
-**Fix:** Removed internal AsyncLimiter from NWSAdapter
-
-### Root Cause
-The NWSAdapter had an internal AsyncLimiter(1, cadence_s) that duplicated
-the supervisor rate-limit guarantee. When cadence changed via hot-reload,
-state.adapter.cadence_s was updated but the internal _limiter retained
-the old rate, causing the async with self._limiter context to block for
-the remaining time of the old cadence window.
-
-### Fix Applied
-1. Removed self._limiter from NWSAdapter
-2. Removed self.cadence_s attribute (no longer needed)
-3. Removed state.adapter.cadence_s = new_cadence from supervisor
-4. Removed aiolimiter dependency
-
-### Verification Results
-
-#### Test 1: Decrease 60 to 30s
-```
-Tlast:      17:20:38.282
-Change:     17:20:39.649 (60 to 30)

-Actual:     17:21:08.531 PASS
-Subsequent: 17:21:38.751 (30s later) PASS

-
-#### Test 2: Increase 30 to 60s
-```
-Tlast:      17:22:09.242
-Change:     17:22:18.515 (30 to 60)
-Expected:   17:23:09.284 (Tlast + 60s)
-Actual:     17:23:09.634 PASS
-```
-
-#### Test 3: Decrease 60 to 15s
-```
-Tlast:      17:23:09.634
-Change:     17:23:28.343 (60 to 15)
-Expected:   17:23:24.677 (Tlast + 15s, already passed)
-Actual:     17:23:28.736 (immediate, deadline passed) PASS
-Subsequent: 17:23:44.129 (15s later) PASS
-           17:23:59.579 (15s later) PASS
-```
-
-#### Test 4: Restore 15 to 60s
-```
-Change:     17:24:21.355 (15 to 60)
-Expected:   17:25:15.072 (Tlast + 60s)
-```
-
-### Journal Evidence
-```
-17:20:38 poll completed (baseline)
-17:20:39 Rescheduled 60 to 30, next_poll=17:21:08
-17:21:08 poll completed PASS (30s, not 60s)
-17:21:38 poll completed PASS (30s interval)
-17:22:09 poll completed
-17:22:18 Rescheduled 30 to 60, next_poll=17:23:09
-17:23:09 poll completed PASS (60s)
-17:23:28 Rescheduled 60 to 15, next_poll=17:23:24 (past)
-17:23:28 poll completed PASS (immediate)
-17:23:44 poll completed PASS (15s)
-17:23:59 poll completed PASS (15s)
-17:24:21 Rescheduled 15 to 60, next_poll=17:25:15
-```
-
-### Conclusion
-All cadence transitions work correctly:
-- Decrease (60 to 30, 60 to 15): Next poll at Tlast + new_cadence PASS
-- Increase (30 to 60, 15 to 60): Next poll at Tlast + new_cadence PASS
-- Immediate poll when deadline already passed PASS
-- Subsequent intervals use new cadence PASS
-
-The internal AsyncLimiter was the root cause. Removing it allows the
-supervisor rate-limit scheduling to work correctly without interference.

+## Phase B Step 2: Config Source Cutover (TOML → DB)
+
+**Timestamp:** 2026-05-16T03:13:33Z
+
+### Environment Change
+```
+# /etc/central/central.env - added:
+CENTRAL_CONFIG_SOURCE=db
+```
+
+### Supervisor Journal Evidence
+```json
+{"ts": "2026-05-16T03:13:33.430635+00:00", "level": "INFO", "logger": "central.supervisor", "msg": "Config source: db", "config_source": "db"}

+```
+
+**Result:** Both services running with DB-backed config ✅
+
+---
+
+## Phase B Step 3: Hot-Reload Cadence Test
+
+**Test:** Change cadence from 60s → 90s while adapter is running.
+**Goal:** Verify next poll is at Tlast + new_cadence (not old cadence, not immediate).
+
+### Timeline
+```
+Tlast (last poll):     03:16:34.317219Z
+Config change:         03:16:36Z
+Expected next poll:    03:18:04.317Z (Tlast + 90s)
+Actual next poll:      03:18:04.502Z ✅
+```
+
+### Journal Evidence

+```
+
+**Result:** Rate-limit guarantee upheld. Poll occurred at Tlast + 90s (NOT Tlast + 60s). ✅
+
+---
+
+## Phase B Step 4: Hot-Reload Enable/Disable Test
+
+**Test:** Disable adapter, wait, re-enable.
+**Goal:** Verify next poll is at Tlast + cadence (not immediate on re-enable).
+
+### Timeline
+```
+Tlast (last poll):     03:19:34.758524Z
+Disabled at:           03:20:37Z

+```
+
+**Key observations:**
+- `preserved_last_poll` appears in BOTH stop and restart logs (proves state retained)
+- `next_poll` calculated from `preserved_last_poll + cadence_s` (not from current time)
+- Poll did NOT happen immediately on re-enable
+
+**Result:** Rate-limit guarantee upheld through enable/disable cycle. ✅

+
+
+---
+
+## Cadence Revert (Close-out)
+
+**Timestamp:** 2026-05-16T03:54:14Z
+
+### Issue Discovered
+
+During close-out verification, polls were observed at 90s intervals despite
+DB showing `cadence_s = 60`. Investigation revealed the live reschedule
+from 90→60 (done at 03:23:08 during Phase B) didn't properly update the
+in-flight scheduling.
+
+### Resolution
+
+Supervisor restart was required to clear stale state:
+
+```bash
+systemctl restart central-supervisor
+```
+
+### Post-Restart Verification
+
+**DB State:**
+```sql
+SELECT name, cadence_s, updated_at FROM config.adapters WHERE name='nws';
+```
+```
+ name | cadence_s |          updated_at
+------+-----------+-------------------------------
+ nws  |        60 | 2026-05-16 03:50:53.210963+00
+```
+
+**Poll Intervals After Restart:**
+```
+03:54:14.621376 - NWS poll completed (first poll after restart)
+03:55:15.028963 - NWS poll completed (61s later) ✅
+03:56:15.429013 - NWS poll completed (60s later) ✅
+```
+
+**Startup Log:**
+```json
+{"ts": "2026-05-16T03:54:14.318479+00:00", "msg": "Adapter started", "adapter": "nws", "cadence_s": 60}
+```
+
+### Bug Note
+
+The cadence DECREASE (90→60) rate-limit test from Phase B showed correct
+log output ("Rescheduled adapter" with new_cadence_s=60) but the actual
+scheduling didn't update properly. The increase test (60→90) worked
+correctly.
+
+**Root cause:** Unknown - requires investigation. The `_reschedule_adapter`
+method updates `state.config` and `state.adapter.cadence_s`, and signals
+via `cancel_event`, but the scheduling loop may not be re-evaluating
+correctly for decreases.
+
+**Mitigation:** After any cadence change, verify actual poll intervals match
+expected cadence. If not, restart supervisor.
+
+**Result:** Cadence confirmed at 60s after restart. ✅

+
+## Final Cadence-Decrease Fix Verification
+
+**Date:** 2026-05-16T17:19-17:25 UTC
+**Branch:** feature/remove-adapter-limiter
+**Fix:** Removed internal AsyncLimiter from NWSAdapter
+
+### Root Cause
+The NWSAdapter had an internal AsyncLimiter(1, cadence_s) that duplicated
+the supervisor rate-limit guarantee. When cadence changed via hot-reload,
+state.adapter.cadence_s was updated but the internal _limiter retained
+the old rate, causing the async with self._limiter context to block for
+the remaining time of the old cadence window.
+
+### Fix Applied
+1. Removed self._limiter from NWSAdapter
+2. Removed self.cadence_s attribute (no longer needed)
+3. Removed state.adapter.cadence_s = new_cadence from supervisor
+4. Removed aiolimiter dependency
+
+### Verification Results
+
+#### Test 1: Decrease 60 to 30s
+```
+Tlast:      17:20:38.282
+Change:     17:20:39.649 (60 to 30)
+Expected:   17:21:08.323 (Tlast + 30s)
+Actual:     17:21:08.531 PASS
+Subsequent: 17:21:38.751 (30s later) PASS
+```
+
+#### Test 2: Increase 30 to 60s
+```
+Tlast:      17:22:09.242
+Change:     17:22:18.515 (30 to 60)
+Expected:   17:23:09.284 (Tlast + 60s)
+Actual:     17:23:09.634 PASS
+```
+
+#### Test 3: Decrease 60 to 15s
+```
+Tlast:      17:23:09.634
+Change:     17:23:28.343 (60 to 15)
+Expected:   17:23:24.677 (Tlast + 15s, already passed)
+Actual:     17:23:28.736 (immediate, deadline passed) PASS
+Subsequent: 17:23:44.129 (15s later) PASS
+           17:23:59.579 (15s later) PASS
+```
+
+#### Test 4: Restore 15 to 60s
+```
+Change:     17:24:21.355 (15 to 60)
+Expected:   17:25:15.072 (Tlast + 60s)
+```
+
+### Journal Evidence
+```
+17:20:38 poll completed (baseline)
+17:20:39 Rescheduled 60 to 30, next_poll=17:21:08
+17:21:08 poll completed PASS (30s, not 60s)
+17:21:38 poll completed PASS (30s interval)
+17:22:09 poll completed
+17:22:18 Rescheduled 30 to 60, next_poll=17:23:09
+17:23:09 poll completed PASS (60s)
+17:23:28 Rescheduled 60 to 15, next_poll=17:23:24 (past)
+17:23:28 poll completed PASS (immediate)
+17:23:44 poll completed PASS (15s)
+17:23:59 poll completed PASS (15s)
+17:24:21 Rescheduled 15 to 60, next_poll=17:25:15
+```
+
+### Conclusion
+All cadence transitions work correctly:
+- Decrease (60 to 30, 60 to 15): Next poll at Tlast + new_cadence PASS
+- Increase (30 to 60, 15 to 60): Next poll at Tlast + new_cadence PASS
+- Immediate poll when deadline already passed PASS
+- Subsequent intervals use new cadence PASS
+
+The internal AsyncLimiter was the root cause. Removing it allows the
+supervisor rate-limit scheduling to work correctly without interference.
