There was a problem hiding this comment.
The new text is accurate. I checked it against calculateCeiling in packages/core/src/session/compaction.ts and the per-field limit merge in packages/core/src/config/plugin/provider.ts. These parts all match the code: input before context, the 16,000-token floor only for windows of at least 32,000 tokens, an explicit buffer replacing the default reserve, the 272,000 → 244,800 example, and no automatic compaction when both limits are unknown. The /providers#models link points at an existing section.
Public API is unchanged (docs only).
No blocking concerns.

Issue for this PR
Closes #52954
Type of change
What does this PR do?
Document input-limit precedence, the default reserve and its small-window exception, explicit buffer behavior, and per-field model limit overrides. Updated against current dev: the reserve is now 15%, so the 272,000-token example reserves 40,800 and compacts at 231,200. Preserve the newer full-conversation summary explanation and provider portability text while resolving the conflict.
How did you verify your code works?
calculateCeiling,RESERVE_SHARE, the existing 231,199/231,200 regression, and model-limit merge paths against the prose.bun run checkpasses. Exact patch and source hashes match head838dc57.git diff --checkpasses. This is documentation-only and changes no public API.Screenshots / recordings
