The optional output-token cap is forwarded together with tool budgets through Goal metering. Its default delegates to `chat_limited`, which preserves existing custom Model implementations and rejects unsupported nonempty caps; custom adapters bound their own internal buffers, while Engine checks their emitted calls before execution. Summaries have a zero-call budget. `Limits` gains `max_tool_buffer_bytes`; `NativeFactory`/`NativeExecutor` gain `tool_call_limits`, requiring updates to explicit struct initializers. Constructors provide defaults. No client protocol methods or snapshot format change. -Compaction retains the original goal and recent content without splitting completion/tool-result or opaque-reasoning boundaries. Summaries are at most 16 KiB with throughItemId and a persisted checkpoint. Network failures retry the same summary input without consuming validation attempts. Empty or pseudo-tool summaries get one retry; subsequent failure permits explicitly marked DEGRADED CONTEXT only if it reduces input, otherwise the Turn fails. Cancellation preserves the old checkpoint. Compaction never deletes history, journals or Turn tool state. +Compaction replays every real user message covered by the checkpoint verbatim and in chronological order, independently of the summary. The initial automatic Goal-continuation item is excluded using persisted Turn origin; subsequent steering in that Turn is retained. Later corrections take precedence over conflicting summary claims. This uses the existing event archive and survives repeated compaction and restart without a new snapshot format. Children retain their own task input and corrections; a parent must explicitly send relevant revisions to existing children. Original messages are not promoted to system instructions or silently truncated, so large user input alone may prevent reduction. Complete tool-call/result and opaque-reasoning groups remain paired. Internal summary controls and validation retries use system messages. A valid summary must fit 16 KiB and the actual available net reduction; invalid summaries get one validation retry, and bounded raw-evidence fallback never nests an older DEGRADED checkpoint. Impossible reductions are skipped before calling the summarizer; archive and execution journals are not deleted. Cancellation preserves the previous checkpoint and gives an already-open stream up to one second to settle trailing usage without executing output tools. Missing usage stays UNKNOWN. `areal/context/compacted` additionally reports `summaryInputBytes` (the pre-summary snapshot size), `beforeEstimatedTokens`, `afterEstimatedTokens`, `targetTokens`, `summaryBytes`, `generatedSummaryBytes`, `summaryBudgetBytes`, `degradationReason` (null, `summary_unavailable`, or `insufficient_net_saving`), and `retainedUserMessages`. Counts include projected user-role messages; media are retained with their original references. With `limits.context_compaction_enabled=false`, exceeding an automatic threshold fails the Turn and explicit `areal/context/compact` returns an error without writing a checkpoint. See [context limits](../guides/configuration.en.md#models-and-limits).

Other messages retain their order. This does not modify persisted history or Responses message/encrypted-reasoning replay. Changing live state can therefore reduce Chat prefix-cache reuse. When a summary exceeds 16 KiB, Core drains its stream under the existing idle deadline and cancellation rules, collects trailing usage, then rejects the summary using the existing bounded format retry. Oversized text alone no longer discards arriving usage. Truly missing usage remains UNKNOWN and does not automatically resume a Goal. + +New request-state snapshots persist the internal `areal_context` role. Chat projects them as user-role status data at their original positions, with a fixed explanatory rule at the beginning; they grant no new user authorization and Core still enforces permissions and budgets. Actual system rules remain consolidated at the beginning for templates requiring a single initial system message. Responses maps the internal role back to system. Historical system snapshots are not silently migrated; older sessions may only obtain fully stable prefixes after compaction or a new session.
