Three small, ship-able-now changes from the past day's issue triage:
1. Client-side detection of the v1.8.0 bad-auth decoy HTML
(#404 w0l4i, #310 sina-b4hrm)
When mhrv-rs gets back the decoy HTML body that v1.8.0's Code.gs/
CodeFull.gs/tunnel-node return on bad AUTH_KEY, the client now
string-matches the body's distinctive "The script completed but
did not return anything" sentinel and emits an explicit ERROR
line naming AUTH_KEY mismatch as the likely cause + walking the
user through "redeploy as new version" + the DIAGNOSTIC_MODE
escape hatch — instead of the previous cryptic "WARN batch
failed: bad response: no json in batch response: <!DOCTYPE...".
Saves users hours of debugging. Reported pattern hits everyone
who edits Code.gs's AUTH_KEY without redeploying as a new version
(Apps Script doesn't auto-pick-up that change).
2. script_id in every batch-failure log (#404 w0l4i)
Previously WARN batch-failed lines didn't say which deployment
failed. In multi-deployment setups (5–10 deployments where
some have stale AUTH_KEY), users couldn't identify the culprit
without the per-deployment curl probe loop.
All four failure paths in tunnel_client::fire_batch — timeout,
bad response, decoy detection, missing-response-in-batch — now
include the script_id short prefix: `batch failed (script
AKfycbz4): ...`. Combined with #1 above, this is the first
reliable diagnostic for the "1 of 8 deployments has bad
AUTH_KEY" pattern.
3. New disable_padding config flag (#391 EBRAHIM-AM)
Default false (padding active = stronger DPI defense). For
users on heavily-throttled ISPs where v1.8.0's ~25% bandwidth
overhead from random padding compounds with the throttle and
pushes borderline-working batches into timeouts, setting
`"disable_padding": true` in config.json recovers headroom at
the cost of losing length-distribution DPI defense.
Don't flip on speculatively — only enable if you've measured
actual throughput improvement on your specific ISP path. For
users where Apps Script outbound flows freely, padding is free
defense.
Tested:
- cargo build --release --bin mhrv-rs: clean
- cargo build --release --bin mhrv-rs-ui --features ui: clean
- cargo test --release --lib: 154 passed
- UI FormState round-trips disable_padding through save/load
