docs/v1.9_RELEASE_NOTES.md, v1.9.1_HYBRID_FIX.md, v1.9.2_WIFI_RESILIENCE.md
were internal working documents (incomplete checklists, dev notes).
CHANGELOG.md already covers all versions — links removed, status updated to v1.9.3.

src/clock_ntp_ota_v1.9.ino was a duplicate of firmware/clock_ntp_ota_v1.9/
that had already drifted out of sync. Removing it eliminates the need to
patch both copies on every PR.
Updated CONTRIBUTING.md build path to point to firmware/clock_ntp_ota_v1.9.

working notes not intended for contributors.

WiFi.begin() without params connects to any SDK-cached network, including
open public hotspots, and then overwrites config.ssid with the wrong SSID.
Now Try 1 (SDK credentials) is only attempted on first boot when no SSID
is configured. Once the user has saved credentials, we go straight to
Try 2 (EEPROM config), so the correct network is always used.

- Use localTime instead of epochTime when formatting date string,
so date rolls over at local midnight, not UTC midnight (fixes#5)
- Remove WEATHER_SUCCESS state assignment that blocked periodic refresh;
state correctly stays WEATHER_IDLE after successful fetch (fixes#7)
- Fix weather debug page "Last update" to show elapsed seconds
(millis() - lastUpdate) instead of raw timestamp
Applied from PR #6 by @Mysteoa with a compilation fix in web_server.cpp
(missing closing parenthesis in snprintf_P call).

## Problem
Previous versions would clear WiFi credentials on connection failure,
requiring manual reconfiguration via captive portal after each WiFi outage.
## Solution
- Never clear credentials on connection failure
- Infinite retry with exponential backoff (5s → 10s → 20s → ... → 5min max)
- Fallback AP ("TJ56654-Setup") enabled after ~5 min of failed attempts
- Dual STA+AP mode allows configuration while still retrying connection
- AP automatically disabled when WiFi reconnects
## Changes
### WiFi Credential Handling
- Try SDK-stored credentials first (from WiFiManager)
- Fall back to EEPROM config if SDK credentials fail
- Fixes OTA update credential loss issue
### User Experience
- Display shows "No WiFi" with retry countdown instead of cryptic numbers
- "!" indicator in date line when WiFi is disconnected
- Clock continues running with last synced time during outage
### Network Activity (~50 requests/day)
| Service | Interval | Endpoint |
|---------|----------|----------|
| NTP | 1 hour | pool.ntp.org:123 (UDP) |
| Weather | 30 min | api.open-meteo.com (HTTP) |
| mDNS | continuous | 224.0.0.251 (multicast) |
