Under S3 the chat of a member's session lagged a whole turn behind the terminal: claude-home.js located transcripts with fs.existsSync, which is access(2) — run by the kernel with capabilities cleared — so the unit's CAP_DAC_READ_SEARCH could not see past the member's 0700 ~/.claude/projects. Every lookup fell back to the import-time snapshot, which is only refreshed now and then. Transcript finders and the /transcripts route now use stat.

|
* @file Regression: transcript lookups in claude-home.js find a file by
|
|
* `stat`, never `fs.existsSync`. existsSync is access(2), which the kernel runs
|
|
* with the capabilities cleared, so under S3 it reported a member's live
|
|
* transcript (behind their 0700 `~/.claude/projects`) as missing and the chat
|
|
* served the stale import-time snapshot — a whole turn shown in the terminal
|
|
* never reached the chat. Here `fs.existsSync` is stubbed to answer "no" for
|
|
* everything under the temp Claude home, as access(2) does for the unit.
