The summarization request no longer dispatches agent/request — that seam shapes the loop's conversation requests; a hand-built one-shot's interception surface is llm/stream, like every other direct call. The model comes from summarizationModel falling back to the agent's own. The turn/step parameters existed on the compact seam only to feed the agent/request dispatch and leave compactIfNeeded/compactRegion. Groundwork for making every conversation request a pure function of the session log (reconstructability RFC, this branch): the seam split keeps the loop's request path as the single thing the log must explain. Ported from worktree-prompt-prefix-stability (PR #162) where it was review-converged; catalog and producer/consumer graphs regenerated.
compact/ — compaction capability family
A three-package capability seam (see capability seams): an abstract compaction interface, a backend that summarizes, and the model-facing tool that consumes it. The interface and a first backend (compact-basic/) exist; the consumer tool is deferred. All product packages.
| Package | Role | ctx key |
|---|---|---|
compact/ |
Abstract compaction seam (interface + compact/* events + CompactionResult) |
ctx.compact |
compact-basic/ |
A backend: chars-per-token estimation (charsPerToken, default 4) + token-budget retention + llm.stream() summarization |
(registers ctx.compact) |
tool-compact/ (deferred) |
Model-facing /compact tool over ctx.compact |
(registers on ctx.tools) |
The interface lives at compact/compact/, the backend at compact/compact-basic/. Unlike the bash seam, it depends on dsh-session and dsh-llm — its verbs are defined over a Session and its output is the ContentBlock vocabulary, so the contract cannot be expressed without naming them. That deviation from the "interface depends only on cordis" guidance is intentional and recorded in the compaction capability-seam RFC. A tokenizer- or template-based backend would replace compact-basic without touching the interface or the tool.
