DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Remote startup timing accepts numbers supplied by the runner

Under the hood
Useful2 Signal3
Sessions Notable not in their notes

On remote runs, startup timings can be supplied by the runner through an environment variable.

CCR_RUNNER_STARTUP_TIMINGCLAUDE_CODE_REMOTE
What

On remote runs, startup phase timing can merge a JSON blob from the CCR_RUNNER_STARTUP_TIMING environment variable into the reported figures, validating each field for type, range and pattern: names must be lowercase with underscores, and numbers and phase durations are capped. Prewarm, prefetch and delta-reset values from the environment are reported alongside. Nothing is reported unless CLAUDE_CODE_REMOTE is set.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
