 `foldDegraded` is gone from `ConversationSnapshot`, and with it the padding sentinels, the `baseSeq` arithmetic they needed, and `degradedSeqs()`. They existed only to satisfy the core fold's `seq === index` assertion and to survive its throw; the fold they describe is no longer run. Deleting the flag is part of the fix, not cleanup after it — `degradedSeqs()` was already almost the log-ordered projection, reached after a thrown error instead of intended.
 
-The marker's summary text, replaced-item count, and estimated shadowed-token count come from the checkpoint's cited `compact/summary` event, never from the framed checkpoint payload, which is an instruction envelope written for the model. A window cut that left that event outside makes those fields unavailable, the same soft-fall as a call-less tool result, and a later page supplying the event resolves them.

 The [manual compaction command](../feature/2026-07-30-queued-manual-compaction.md) returns the summary event's seq as the successful `CommandResult.sourceEventSeq`, and `command/done` persists that optional reference. Chat pairs only a successful named `/compact` command whose reference equals exactly one loaded `CompactionSummaryNode.summaryEventSeq`. The running command first renders `compact · Compacting context…`; after the checkpoint lands, the same React key renders one collapsed `compact` disclosure at the checkpoint's flow position with the count and token estimate. Input rejection, no compactable history, cancellation, and failure remain generic command rows with complete handler-authored text. Automatic compaction has no command reference and keeps the standalone context-compacted marker.

 Recognition needs all three conditions, as in the terminal: `event.type === 'user/message'`, the compaction seam's checkpoint plugin source, **and** `isReplacementSurfaceEvent(event)`. A plugin-sourced `user/message` that *appends* is injected context — a session-reference card — not a compaction.
 
-What is unreachable from a `packages/client/*` program is `dsh-compact`'s **root**, not the package. The root reaches `dsh-session`'s root, whose cordis `Context` merge declares the host `sessions: SessionStore` against the client's `sessions: ISessions` — `TS2717`, the one-program-per-side rule in [development.md](../../../../docs/development.md#typescript-project-layout) — and that holds for a type-only import too, because the collision is a compiler fact rather than a bundler one.

-The repo's answer to exactly this is a cordis-free leaf subpath, and this change adds one: `COMPACT_CHECKPOINT_SOURCE` and `isCompactCheckpointSource` now live in `packages/compact/compact/src/checkpoint.ts`, which imports no cordis and augments no module (the `dsh-commands/brand` / `dsh-llm/message` shape), and the root re-exports both so every host-side consumer — the terminal's chat helpers, `dsh-session-reference`'s projection — is unchanged.

-Renaming the Service Definition's plugin id is now a compile error in the client: `TS2322: Type '"compact"' is not assignable to type '"compaction"'`. The import must stay **type-only** — a value import of any `@deepseek-ai` package that is neither a platform module nor an inline-safe wire layer is rejected by the client purity gate (`packages/client/tsdown.client.ts`), whose own message records that type-only imports are erased and never reach it. A type-only leaf import needs both a `tsconfig.base.json` `paths` entry and `{"path": "../../compact/compact"}` in `packages/client/runtime/tsconfig.json` `references`: composite `rootDir` rules apply to erased imports as well, and without the reference the diagnostic is `TS6059`/`TS6307`.

 `packages/client/ui-conversation/tests/conversation-node-definitions.client.spec.ts` is the behavioral half, driving the compaction Definition with checkpoint and provenance records and proving that an older page can fill missing summary data. The Definition's type-only leaf import keeps the client isolated from the compact package root and the host-side `Context` merges reachable through it.

 ## Alternatives considered
 
-**Value-import the predicate** from the new leaf and add `dsh-compact` to the client `INLINE_SAFE` allowlist. Rejected: the client needs the plugin id, not the predicate — a type is enough, and an erased import never reaches the purity gate, so nothing has to be admitted to it. The allowlist would only matter for a value import, and there it is a poor trade: `INLINE_SAFE` matches on specifier *prefix*, so admitting the package admits its cordis-importing root along with the leaf.

 **A bare shape rule** — any replacement `user/message` is a compaction. Rejected: correct today only because compaction is the sole producer of replacement `user/message`s, with nothing to catch it if that changes. The pinning spec costs one file and removes exactly that risk.
