Harden AC rules with workday+weather fallbacks (v2)

Replace the three live AC automations in place (same ids -> same entity_ids,
continuous history/traces):

* pre-cool & peak-setback: the workday check moves out of a blocking
  `condition` into template logic that falls back to a plain Mon-Fri test when
  binary_sensor.workday_sensor is unavailable/unknown. Previously a dead sensor
  silently skipped the run.
* pre-cool: weather.get_forecasts now uses continue_on_error, and a
  `fc is defined and is mapping` guard falls back to an assumed 88F high (->70F
  regular pre-cool) when the forecast hard-errors or returns nothing.
* peak-ends: unchanged behavior (runs daily), documented only.

Add AUTOMATIONS.md (identity model, per-rule spec, failure-mode table, deploy
steps) and deploy.py (pushes automations/*.yaml to the HA config API by id).

Fallbacks verified empirically against the live automations via execution
traces before this commit. Also removed throwaway server-side debug automations
(three TEST spoofs + the ac_flap_1758_1820 experiment).

+# Home Assistant automations
+
+Source of truth for the AC peak-shaving automations on the HA server
+(`192.168.128.3:8123`). This repo is authoritative; HA is a **deploy target**
+reached only through its REST config API — HA never sees these files directly.
+
+## Identity model (how a file becomes a live automation)
+
+```
+ file (git)                        Home Assistant
+ automations/ac_peak_setback.yaml  ──deploy.py──▶  POST /api/config/automation/
+   id:    ac_peak_setback              (by id)         config/ac_peak_setback

+```
+
+| Identifier | Example | Set by | Used by | Change it? |
+|---|---|---|---|---|
+| **file name** | `ac_peak_setback.yaml` | you | git only (HA never sees it) | freely |
+| **`id`** | `ac_peak_setback` | you (in YAML) | config API URL, traces, `automation.trigger` | **never** (primary key) |
+| **`alias`** | `AC - Peak setback to 82` | you (in YAML) | UI name; seeds `entity_id` at first create | rarely |
+| **`entity_id`** | `automation.ac_peak_setback_to_82` | HA, from `slugify(alias)` | dashboards, other automations, scripts | sticky once registered |
+
+Key point: **`entity_id` derives from `alias`, not `id`.** Reference automations
+elsewhere in HA by their `entity_id`.
+
+## Deploying
+
+```bash
+source ~/.bashrc                 # provides HA_API_KEY (long-lived token)
+python3 deploy.py --check        # parse only, no writes
+python3 deploy.py                # replace all three in place (same ids)
+python3 deploy.py ac_peak_ends   # deploy just one by id
+```
+
+`deploy.py` POSTs each file to `/api/config/automation/config/<id>`. Same `id`
+= in-place replacement, so `entity_id`, run history, and traces stay continuous.
+
+## The rules
+
+All act on `climate.t6_pro_z_wave_programmable_thermostat_with_smartstart`.
+The "peak" window is **14:00–19:00 (2–7 PM) local (America/New_York)**.
+
+### 1. `ac_precool_before_peak` — Pre-cool before peak
+- **12:00**, work days. Fetches today's daily forecast high and pre-cools:
+  | forecast high | setpoint |
+  |---|---|
+  | ≥ 90°F | 68 |
+  | ≥ 85°F | 70 |
+  | ≥ 80°F | 71 |
+  | < 80°F | *(no pre-cool)* |
+- **Fallbacks:** workday sensor broken → Mon–Fri; forecast broken → assume 88°F
+  high → 70°F (`continue_on_error` covers a hard error, the `fc is defined and is
+  mapping` guard covers an empty/None response).
+
+### 2. `ac_peak_setback` — Peak setback to 82
+- **14:00**, work days. Sets cool / **82°F** to coast through the peak.
+- **Fallback:** workday sensor broken → Mon–Fri.
+
+### 3. `ac_peak_ends` — Peak ends, return to 74
+- **19:00**, **every day** (intentionally not workday-gated). Sets **74°F**.
+- No external dependencies, so nothing to fall back on.
+
+## Failure-mode design
+
+Two independent dependencies, each handled so a failure keeps sensible defaults
+instead of skipping:
+
+| Failure | Symptom | Handled by | Default taken |
+|---|---|---|---|
+| Workday/holiday sensor unavailable | `states()` ≠ `on`/`off` | `{% if wd in ['on','off'] %}…{% else %} now().weekday()<5` | Mon–Fri |
+| Weather service raises | action would abort | `continue_on_error: true` | run continues |
+| Weather returns empty/None | `fc` undefined / not a mapping | `{% if fc is defined and fc is mapping %}…{% else %} 88` | regular pre-cool (88→70) |
+
+Verified empirically on 2026-07-09 by forcing each failure against the live
+automations and reading their execution traces (workday → `unavailable` still
+ran the Mon–Fri branch; missing weather entity → `today_high=88`, setpoint 70,
+`script_execution: finished`).
+
+## Changelog
+
+- **2026-07-09 — v1 baseline**: imported the three live automations as-is.
+- **2026-07-09 — v2**: added workday + weather fallbacks to pre-cool and
+  setback (a broken sensor/forecast no longer skips the run). Peak-ends
+  unchanged. Removed throwaway debug automations from the server: the three
+  `TEST - … (spoof, every 1 min)` rules and the `ac_flap_1758_1820`
+  (85/90 flap) experiment.
