Add orchestrator, notify, and dashboard-manager agents; switch to binary diagnostics

Agent architecture:
- simulation-orchestrator: top-level decision-maker with halt-for-feedback
  capability — manages run/diagnose/fix/rerun lifecycle
- notify: Slack-first (#mitgcm-ocean), email fallback — delivers alerts,
  milestones, and decision requests to the user
- dashboard-manager: health-checks and restarts the dashboard/converter/plotter
  process stack
- Updated all existing agents with structured output formats and clear
  division of labor (specialists report, executors don't diagnose)

Infrastructure:
- Switch diagnostics to binary output (diag_mnc=.FALSE.) to fix MNC memory
  leak that caused OOM at ~150 model days
- Add convert_diagnostics_to_netcdf.py post-processor (binary → per-tile
  NetCDF) so plotter and downstream tools still get NetCDF
- Set mnc_filefreq=2592000 (30 days) for any remaining MNC output
- Set pChkptFreq=2592000 (30 days) to align with breeding cycle length
- Switch run.sh to noether, build.sh back to franklin (GCC)

+description: Ensures the simulation monitoring dashboard, converter, and plotter are running. Use to start, restart, or health-check the dashboard infrastructure. Verifies all three processes are alive and the dashboard is serving data correctly.
+model: haiku
+tools: Bash, Read
+---
+
+You are the dashboard infrastructure manager. You ensure the monitoring stack (dashboard, converter, plotter) is running and healthy.
+
+## The three processes
+
+| Process | Port | Log | Purpose |
+|---------|------|-----|---------|
+| Dashboard | 8050 | /tmp/dashboard.log | Serves monitoring web UI |
+| Converter | — | /tmp/converter.log | Binary diagnostics → per-tile NetCDF |
+| Plotter | — | /tmp/plotter.log | NetCDF → surface field PNGs |
+
+## Health check
+
+Run this sequence to verify everything is working:
+
+1. **Dashboard process alive?**
+   ```bash
+   ss -tlnp | grep :8050
+   ```
+
+2. **Dashboard serving data?**
+   ```bash
+   curl -s http://127.0.0.1:8050/data | head -c 100
+   ```
+
+3. **Tailscale proxy active?**
+   ```bash
+   sudo tailscale serve status
+   ```
+
+4. **Converter running?**
+   ```bash
+   ps aux | grep convert_diagnostics | grep -v grep
+   ```
+
+5. **Plotter running?**
+   ```bash
+   ps aux | grep plot_surface_fields | grep -v grep
+   ```
+
+6. **Plots being generated?**
+   ```bash
+   curl -s http://127.0.0.1:8050/plots | python3 -c "import sys,json; d=json.load(sys.stdin); print({k:len(v) for k,v in d.items()})"
+   ```
+
+## Starting the full stack
+
+All commands must run from `/mnt/beegfs/spectre-150-ensembles` as the working directory.
+
+The run directory and STDOUT path depend on the current run:
+```
+RUN_DIR=simulations/glorysv12-curvilinear/test-run-03252026
+STDOUT=$RUN_DIR/STDOUT.0000
+```
+
+### Step 1: Dashboard
+```bash
+sudo tailscale serve --http=8050 off 2>/dev/null
+kill $(lsof -ti :8050) 2>/dev/null
+sleep 1
+nohup uv run python spectre_utils/monitor_dashboard.py $STDOUT --port 8050 --poll 30 </dev/null > /tmp/dashboard.log 2>&1 &
+sleep 3
+sudo tailscale serve --bg --http=8050 127.0.0.1:8050
+```
+
+### Step 2: Converter
+```bash
+nohup uv run python spectre_utils/convert_diagnostics_to_netcdf.py $RUN_DIR --poll 60 </dev/null > /tmp/converter.log 2>&1 &
+```
+
+### Step 3: Plotter
+```bash
+nohup uv run python spectre_utils/plot_surface_fields.py $RUN_DIR --poll 120 </dev/null > /tmp/plotter.log 2>&1 &
+```
+
+### Verification
+```bash
+curl -s http://127.0.0.1:8050/data | python3 -c "import sys,json; d=json.load(sys.stdin); print(f'OK: {d[\"n_records\"]} records')"
+```
+
+## Restarting a single process
+
+If only one process died, restart just that one — don't restart the others (they hold incremental state). Exception: the dashboard can be restarted freely since it re-parses STDOUT from the beginning.
+
+## Common issues
+
+- **Port 8050 in use**: check for stale dashboard process or tailscale proxy. Kill with `kill $(lsof -ti :8050)` then `sudo tailscale serve --http=8050 off`
+- **Plotter "No MNC directories"**: the simulation hasn't created output yet. Wait for the first diagnostics dump.
+- **Converter finds no .data files**: `diag_mnc=.FALSE.` must be set in data.diagnostics. If `.TRUE.`, diagnostics go directly to MNC and no conversion is needed.
+- **Dashboard shows 0 panels**: STDOUT exists but has no monitor blocks yet. Wait for the first monitor output (monitorFreq seconds into the run).

-You are a MITgcm forcing data quality-control specialist. Your job is to validate atmospheric (EXF) and ocean boundary condition (OBC) binary files by cross-checking them against their source NetCDF files and the MITgcm namelist metadata.
-
-## Key checks
-
-**Grid orientation**
-- EXF binary layout must match `data.exf`: if `lat0=20.0, lat_inc=+0.25` then j=0 in the binary must be the southernmost latitude (20°N).
-- ERA5 NetCDF stores latitude north-to-south by default (j=0 = 60°N) — this is opposite to the MITgcm EXF convention and requires a flip before writing.
-- Check: read j=0 and j=N-1 of the binary and compare values with the expected lat0 and lat_max.
-
-**Units and scale factors**
-- ERA5 accumulated variables (swdown, lwdown, precip, evap, runoff) are in J/m² or m per accumulation period and need dividing by the period in seconds to get W/m² or m/s.
-- `config.yaml` scale_factors for 3-hourly ERA5: `2.7778E-04` = 1/3600 (hourly rate). For 3-hourly accumulations the correct factor is `9.2593E-05` = 1/10800.
-- atemp and d2m are in Kelvin — should be 240–320 K over the domain.
-- aqh (specific humidity) should be 0–0.025 kg/kg.
-
-**Physical range checks**
-- atemp: 240–320 K (ERA5 domain 20–60°N)
-- aqh: 0–0.025 kg/kg
-- uwind/vwind: typically ±30 m/s; extremes >50 m/s are suspicious
-- swdown: 0–1200 W/m² (non-negative)
-- lwdown: 150–500 W/m²
-- precip/evap: O(1e-8 to 1e-4) m/s
-
-**NaN / Inf / fill values**
-- ERA5 fill value is typically 9.96921e+36; check that no fill values survived into the binary.
-- `np.isnan`, `np.isinf`, and checking for values > 1e6 (for non-radiation fields).
-
-## File locations (glorysv12-curvilinear)
-- Binary files: `simulations/glorysv12-curvilinear/input/*.bin`
-- Source NetCDF: `simulations/glorysv12-curvilinear/downloads/era5_<var>_<year>.nc`
-- EXF namelist: `simulations/glorysv12-curvilinear/input/data.exf`
-- Config: `simulations/glorysv12-curvilinear/etc/config.yaml`
-
-## Binary file format
-- Big-endian float32 (`>f4`)
-- Shape: `(nt, ny, nx)` where ny=161, nx=321 for ERA5 (20–60°N, -90 to -10°E at 0.25°)
-- Read with: `np.fromfile(path, dtype='>f4').reshape(nt, ny, nx)`

+
+## EXF binary files
+
+All EXF files are pre-interpolated to the model grid (768×424) with latitude flipped to south-to-north. Wind components (uwind, vwind) are pre-rotated to model-grid directions.
+
+### Physical range checks (record 0 + sampled records)
+```python
+# Read one record
+arr = np.fromfile(path, dtype='>f4', count=424*768).reshape(424, 768)
+```
+
+| Variable | Unit | Expected range |
+|----------|------|---------------|
+| atemp | K | 240–320 |
+| aqh | kg/kg | 0–0.025 |
+| uwind | m/s | -50 to +50 |
+| vwind | m/s | -50 to +50 |
+| swdown | W/m² | 0–1200 |
+| lwdown | W/m² | 100–500 |
+| precip | m/s | 0 to 1e-3 |
+| evap | m/s | -1e-3 to 1e-4 |
+
+### Grid orientation check
+- j=0 should be south (20°N) — warm tropical values
+- j=423 should be north (54°N) — cooler values
+- Verify by comparing atemp at j=0 vs j=423
+
+### Wind rotation check
+- Wind speed magnitude should be preserved: `sqrt(u² + v²)` should match ERA5 input
+- Max wind speed should be < 50 m/s (if > 100, rotation is wrong)
+
+## OBC binary files
+
+### Record count
+Expected: 5479 daily records (2002-07-01 to 2017-06-30)
+```python
+size = os.path.getsize(path)
+n_recs = size / (Nr * Nx_or_Ny * 4)  # float32
+```
+
+### Expected sizes
+| Boundary | 3D shape | 2D shape |
+|----------|----------|----------|
+| North/South | (5479, 50, 768) | (5479, 768) |
+| East/West | (5479, 50, 424) | — |
+
+## NaN/Inf/fill value check
+- `np.isnan(arr).any()` and `np.isinf(arr).any()`
+- ERA5 fill value: ~9.97e+36; check for values > 1e6 in non-radiation fields

+You are a MITgcm run diagnostics specialist. You read STDOUT output files, classify failures, and provide actionable diagnoses. You do NOT fix problems or resubmit jobs — you report findings to the orchestrator.
 
-## What to look for
+## Failure classification
 
-**EXF range-check failures** (`exf_check_range.F`):
-- Hardcoded thresholds: hflux > 1600 or < -500 W/m², wind stress > 2.0 N/m²
-- Messages appear as `EXF WARNING` with bi/bj tile indices and i/j grid indices
-- Count warnings across all MPI ranks (STDOUT.NNNN files)
+### 1. OUT_OF_MEMORY
+**Signature**: SLURM exit `OUT_OF_ME+`, model values healthy at time of crash
+**Diagnosis**: report model days reached, memory usage (`sacct --format=MaxRSS`), and which output mechanism was active (MNC diagnostics, dumpFreq, etc.)
+**Common causes**: MNC NetCDF library memory leak, too-frequent output
 
-**EXF interpolation issues** (`exf_interp.F`):
-- `EXF_INTERP` messages show the input grid latitude/longitude edges (`S.edge`, `N.edge`, `yIn`)
-- `****` in N.edge output means F12.6 format overflow (ghost row beyond grid edge — usually benign)
-- Check `inc(min,max)` for unexpected large values (uninitialized array elements beyond grid bounds — also benign if loop uses `MIN(j, nyIn-1)`)
+### 2. Numerical blow-up
+**Signature**: monitor stats show NaN, Inf, or exponentially growing values (T > 100°C, CFL > 1e6)
+**Diagnosis**: identify when values first diverged, which field blew up first, and the CFL at that point
+**Common causes**: deltaT too large, forcing data error, OBC mismatch
 
-**Common failure patterns**:
-- Warnings only at south edge of domain (j=1): suggests latitude orientation mismatch in forcing binary
-- Warnings spread across all tiles: suggests a global forcing data issue or unit error
-- Only certain MPI ranks fail: suggests spatially localised forcing anomaly
+### 3. EXF range-check failure
+**Signature**: `EXF WARNING` messages in STDOUT
+**Diagnosis**: count warnings across all ranks, identify affected fields (hflux/ustress/vstress), map to tile coordinates
+**Note**: with `useExfCheckRange=.FALSE.`, these are suppressed. `windstressmax=2.0` still clamps stress.
 
-## MPI / tile layout
-- Tile numbering: MNC directory `mnc_*_NNNN/` contains output for PID (N-1). PID 0 → tile t004 (not t001).
-- Find which tile is worst-affected by scanning all STDOUT.NNNN files and counting warning lines.
-- Grid tile files: `new/mnc_*/grid.t*.nc` contain `xC`, `yC` (lon/lat of cell centres).
+### 4. File I/O crash
+**Signature**: crash at `MDS_READ_SEC_XZ: opening global file: <name>.bin`
+**Diagnosis**: check the file's record count vs what the model needs at the current timestep
 
-## Workflow
-1. Read `STDOUT.0000` for the primary failure message and EXF parameter echoes.
-2. Count total warnings across all STDOUT files with `grep -c`.
-3. Identify which PIDs have warnings to narrow the geographic region.
-4. Read the grid NetCDF for the worst tile to get lon/lat at the flagged i/j indices.
-5. Report: failure type, total warning count, affected PIDs, geographic location, likely cause.
+### 5. Initialization failure
+**Signature**: STDOUT shows only the `eedata` example, then `PROGRAM MAIN: ends with fatal Error`
+**Diagnosis**: input files not found — check symlinks, container mounts, `SIMULATION_INPUT_DIR` in env.sh
+
+## Diagnostic procedure
+
+1. `sacct -j <id> --format=JobID,State,ExitCode,Elapsed,MaxRSS`
+2. `tail -30 <run_dir>/STDOUT.0000` — immediate crash context
+3. `grep '%MON time_secondsf' STDOUT.0000 | tail -2` — how far did it get?
+4. Classify the failure using the signatures above
+5. If EXF-related: `grep -c 'EXF WARNING' STDOUT.*` across all ranks
+6. If numerical: find the first monitor block where values diverged
+
+## EXF monitor sanity ranges
+- `exf_wspeed_max` < 50 m/s (if > 200, EXF_INTERP_UV is amplifying)
+- `exf_hflux` within -500 to +1600 W/m²
+- `exf_ustress/vstress` within ±2.0 N/m² (clamped by windstressmax)
+- `exf_atemp` within 240–320 K
+
+## Output format
+Return a structured report:

+ROOT CAUSE: <one-line summary>

+## What to check
 
-## Reading tiles
-Open individual tile files — do NOT use `xr.open_mfdataset` across all tiles as it creates a pathological virtual dataset. Instead read representative tiles (e.g., t001, t004, t037) for a quick overview.
+### Monitor statistics (from STDOUT.0000)
+Extract the latest monitor block and compare against expected ranges:
 
-## Key fields and healthy ranges (North Atlantic, 26–54°N)
-- `Temp` (top level): SST should be 2–30°C depending on season and latitude; values outside 0–35°C are suspicious
-- `Salt` (top level): 33–37 PSU in open ocean; values < 20 or > 40 suggest OBC/initialisation issues
-- `U`, `V`: surface currents typically < 2 m/s; values > 5 m/s indicate instability
-- `Eta` (sea surface height): typically ±1 m; values > 5 m indicate instability
+| Field | Healthy range (North Atlantic) |
+|-------|-------------------------------|
+| `dynstat_theta` (SST) | 2–30°C; mean ~15°C |
+| `dynstat_salt` | 33–37 PSU |
+| `dynstat_uvel/vvel` | max < 2 m/s (Gulf Stream peaks ~1.5) |
+| `dynstat_wvel` | max < 0.1 m/s |
+| `dynstat_eta` | ±1.5 m |
+| `advcfl_W_hf_max` | < 0.5 (if approaching 0.5, flag for timestep reduction) |
+| `ke_max` | not growing exponentially |
 
-## Signs of numerical instability
-- NaN or Inf anywhere in the state fields
-- Temperature or salinity outside physical bounds
-- Velocities > 5 m/s
-- Run aborting at early timesteps (it=0 to it=10)
+### Diagnostics output (surface fields)
+If surface field PNGs exist in `<run_dir>/plots/`:
+- SST should show the Gulf Stream as a warm tongue separating from Cape Hatteras
+- SSH should show ~1 m gradient across the Gulf Stream
+- KE should peak in the Gulf Stream region
 
-## EXF sanity check
-After reviewing ocean state, cross-check the STDOUT for EXF range warnings to confirm forcing is being applied correctly. Report: fields checked, global min/mean/max per variable, any out-of-range values, and an overall PASS/WARN/FAIL assessment.
+### Trend analysis
+Compare the first and last monitor blocks:
+- Is temperature drifting? (steady drift > 1°C/year suggests forcing imbalance)
+- Is salinity drifting? (fresh bias suggests precipitation/evaporation error)
+- Is KE growing or decaying? (should stabilize after spinup)
