+119. **Row 92 lands on Jason's token file, swappable for a proxy key
+    (2026-10-12).** Jason answered Q126 through Mos (sage-0109): "Token
+    saved. This needs to be the initial testing configuration." Mos
+    checked that `~/.config/mosaic-dev/secrets/claude-session.env`
+    exists, is mode 600 and has one `CLAUDE_CODE_OAUTH_TOKEN` line, and
+    read no value. His longer-term ask, credentials set programmatically,
+    maybe through CLIProxyAPI, is Vikunja #237 and waits on Q127. No one

+    - Row 92's unit loads that file with `EnvironmentFile=`. The launch
+      check accepts any provider credential `ENV_ALLOW` already passes
+      (`packages/seat/src/session.mjs:62-64`): `CLAUDE_CODE_OAUTH_TOKEN`,
+      `ANTHROPIC_API_KEY`, or `ANTHROPIC_AUTH_TOKEN` with
+      `ANTHROPIC_BASE_URL`. Swapping in a proxy-issued local key then
+      changes the file, not the code or the unit.
+    - The file name and its one place in the unit and README stay the
+      only references to it, so a later row can rename it in one edit.
+    - Decision 114 still holds: no session traffic goes through
+      CLIProxyAPI until Jason rules, and no agent reads its management
+      key.
