Unlike the bash seam, this interface depends on `@deepseek-ai/dsh-session` and `@deepseek-ai/dsh-llm` — the contract's verbs are defined over a `Session` and its output is the `ContentBlock` vocabulary, so they cannot be expressed without naming those packages. That deviation from the "interface depends only on cordis" guidance is intentional and recorded in the [compaction capability-seam RFC](../../../docs/rfc/implemented/feature/2026-06-18-compaction-capability-seam.md).

## Implementing a backend
Subclass `CompactService`, implement `compactIfNeeded` and `compactRegion`, and load the subclass as a plugin — it registers as `ctx.compact`. A tokenizer-, template-, or model-backed implementation can live as a sibling package without changing callers.
## Model Experience
### Conversation history, when a backend is invoked
**What the model sees**: A successful implementation replaces an older surface range with one user-role summary checkpoint; the raw events stay logged but stop appearing in derived model messages. The seam itself performs no rewrite.
**Token effect**: Zero direct tokens from this interface. A backend trades many retained history tokens for one summary and leaves the recent tail unchanged.
### Transcript supplied to a compaction consumer
**What the model sees**: `renderTranscript()` joins entries with one blank line and renders them exactly as `User: <content>`, `Assistant: <content>`, `Tool result (call <callId>): <content>`, `Tool error (call <callId>): <content>`, `[Context: <content>]`, or `[Steering: <content>]`. Non-text blocks render exactly as `[reasoning: <text>]`, `[tool-call: <name>(<arguments>)]`, `[tool-result: <content>]`, `[tool-result]`, or `[<block-type>]`.
**Token effect**: Data-dependent input tokens are paid only by the auxiliary model or consumer that requests this transcript; the conversation model does not receive a duplicate transcript.
## Known Limitations and Deferred Work
- **No model-facing consumer tier yet** — `@deepseek-ai/dsh-tool-compact` (the `/compact` tool) is deferred; compaction is reachable only via direct `ctx.compact` calls or a backend's auto listener.
- **Single-unit overflow is out of contract** — one retained unit (a closed step or a large pasted `user/message`) alone exceeding the budget cannot be compacted; the call may go out over-budget.
- **A session prefix that alone approaches the window is a configuration error no backend fixes** — compaction shrinks derived history, never the prefix.
- **Request context injected by downstream `agent/request` listeners sits outside pressure accounting** — `compactIfNeeded` counts prefix, derived history, and system prompt only.
