Marty asked for a watchdog on position #220: tell him when they buy their
upgrade and whether Orlando's #30 gets paid.
The chain says it should. #220 sits at Apex with four uplines between them
and #30, and a level-6 upgrade skips exactly those four, so #30 is the first
candidate the contract tests and it passes both gates (level 5 > 4, three
directs). That is a prediction, though, and the watcher does not report
predictions: it reads MemberUpgraded and UplineRewarded off the logs and says
who was actually paid and how much. If somebody else catches it, it says so.
Tested by replaying real history (BACK=600 over a live #319 upgrade) on both
a wide-range endpoint and a chunked 50-block one, then the dedupe guard, then
two outage cases.
The outage cases mattered. A watchdog that dies quietly is worse than no
watchdog, because silence gets read as "nothing happened", so:
- a failed scan never advances the block pointer; unread blocks are read
on the next run rather than skipped
- four consecutive failures sends a warning instead of going quiet, and
both failure paths feed one counter. The first version only counted the
log scan, so a total outage -- where even the block number is unreachable
-- raised straight past the counter, and the one outage most worth
shouting about was the one that would have stayed silent.
Also brings rmc-depth-watch.py into the repo. Both watchers existed only on
core, with no copy anywhere, so a rebuilt box lost them silently. The README
records the restore steps and which Polygon RPCs actually serve eth_getLogs
(publicnode and tenderly take 2000 blocks; drpc and 1rpc cap at 50; four
others refuse outright), measured from core rather than assumed.

Manson asked whether the training videos could be in other languages. A real dub
means re-rendering every video per language: translated Romance-language speech runs
15-25% longer than English and these are slide videos with fixed beat timings, so
swapped audio drifts off what is on screen. That turns 15 files into 75 and makes
every future lesson edit a five-way job. Captions keep ONE video and add small text
tracks beside it, so editing a lesson re-captions that lesson only.
tools/captions.mjs: ffmpeg pulls the audio, ElevenLabs Scribe transcribes with word
timings (the same STT we already use to verify voiceovers), words are grouped into
SENTENCES, and only then translated. Translating cue-by-cue is why most auto-captions
read badly at cue boundaries. Translation goes through our own /api/public/translate,
so every phrase caches forever in translations.json and costs once across the site.
The STT response is cached on disk because it costs money; never pay for it twice.
Language choice is evidence, not instinct. The translation cache shows real member
demand: Italian and French far ahead, then Spanish, then GERMAN - which beats
Portuguese by more than double, the opposite of what we assumed. Proof of concept is
Italian on the 5-minute overview.
Captions are deliberately NOT on by default. An English reader does not want them
forced over the picture; someone who already switched the site to Italian almost
certainly does. public/vtt-lang.js shows the track matching their 🌐 choice and
leaves the player's CC button to do the rest.
Two bugs this caught in my own code, both found by reading the output:
- the line wrapper truncated each cue to two lines and SILENTLY DELETED the overflow,
so "the whole plan fits in one sentence" shipped as "fits in" then "sentence". It
now chunks by the real wrapped line count and never drops a word.
- a one or two word tail ("sentence." alone on screen) folds back into the previous
cue.
The suite asserts all 780 transcript words survive into the English track.
Also: .vtt had no Content-Type mapping, so it served as octet-stream and browsers
silently ignore such a track. qa/captions-e2e.mjs (12 assertions) reads the parsed
cues back out of the player rather than trusting the markup, which is the only way to
catch that class of failure. profiles-unit 28 and gate-e2e 33 still green.
