# Memory index  ->  MEMORY.md

<!-- THIS is the file that loads every session. The facts themselves do NOT.
     That split is the whole trick: the index stays cheap, the detail is
     fetched only when relevant. One line per fact, with a hook after the dash
     so the model can tell whether it needs to open it. -->

# Memory Index

- [Deploy runs from a script, not the CLI](deploy-is-a-script.md) - the obvious
  command silently deploys the wrong config and still exits 0.
- [Why the cache layer exists](cache-rationale.md) - it looks redundant; it is
  not. Removing it caused an outage.
- [TRAP: timestamps are two different formats](timestamp-trap.md) - comparing
  them as strings gives wrong answers that look right.
- [Customer avatar](customer-avatar.md) - who actually reads what we write.

<!-- Keep lines scannable. The hook after the dash is what lets the model
     decide to open the file. A line that just says "Deploy notes" tells it
     nothing, so it either opens everything or opens nothing. -->
