The problem
Every retiring tech is a library on fire.
The knowledge is tribal
The right torque value, the sound of a dying pump, which serial numbers lie — it lives in heads, not documents.
The manual is wrong in the field
Veterans know the pages that are wrong on specific units. Those corrections are documentation you don't have.
The cliff has a date
Retirements aren't a trend, they're a calendar. The day your best tech walks out, every unwritten fix walks out too — and the next tech starts over from the manual that's wrong.
The loop
One recording becomes all three
“LWCO tripped again — gauge glass reads normal…”
“Book says reset. Not on a pre-2018 unit.”
“Crack the blowdown first. Watch — rusty water.”

01 · Record
Techs narrate the job. That's it.
Hit record and talk through the work — live speech-to-text in the truck or on the roof. No forms, no typing, no extra hour at the end of the shift.
- One tap to start; autosaves as they talk
- Exit-interview mode for retiring veterans
02 · Verify
Every card is checked against the recording
Recordings become structured cards — symptom, root cause, fix, warnings — each carrying a verbatim quote that is mechanically verified against the source. Humans approve before anything goes live.
- Verbatim quotes, machine-checked — no AI invention
- The veteran's name on every card
03 · Train
Rookies drill on your jobs, not a textbook
Approved cards become scenario drills. Wrong answers show the veteran's reasoning — that IS the training. Mastery is tracked toward one number: weeks to solo.
- Every drill grounded in a real card, or it's rejected
- Miss a question, learn the why — with attribution

- Honest when neither source covers it
The moment that matters
When the manual and the veteran disagree,
the difference is the answer.
The manual says · p.7
“Once level is confirmed, press the reset button on the LWCO control and restart the burner immediately. Occasional trips during rapid load swings are a normal characteristic of high-demand systems and do not by themselves indicate a fault condition.”
Vulcan Series 900 IO&M Manual · Rev C · 2014
MRMike says · 31 years
“You keep resetting and relighting on a fouled float and one day it doesn't trip when you actually ARE low, and then you've dry-fired it and cooked the crown sheet. Blow down the float chamber first.”
Applies to pre-2018 float-type units · captured June 2026
Caisson surfaces this conflict in every answer it touches — the manual's claim, the veteran's correction, and exactly which units each applies to. Attributed, sourced, reviewable.
