Give durable user context its producer-owned source kind instead of a generic plugin wrapper. The V3-to-V4 conversion preserves the frozen rename and collision rules, all own JSON metadata, event coordinates, and historical request-only kinds. Native catalog and JSONL admission retain source validation so unknown attribution can survive without its producer while malformed owned sources are refused.
Use an explicit user-only RequestUserInput for auxiliary LLM prompts that do not own durable message identity. Auto Review and compaction remove their request-only source registrations while retaining prompt content and freezing; provider serializers and projections keep the same wire data, assistant replay isolation, image ordering, and tool correlation. Session writes, Agent delivery, and recorded title requests continue to require identified durable messages.
Bind the saved compatibility policy only to user sources and qualify tmux location attribution without weakening fixed system, model, or tool semantics. Rebuild the current inventory and unpublished V4 acknowledgement on the actual tool-role parent, preserving its rationale and all accepted historical records. The catalog format version records tooling metadata; Session remains V4. Developer-role policy and activation belong to their own feature.
The latest-master Messages adapter, serialization, request-input typing, EpochHeader reservation, and attribution checks pass 103 tests across five files. The retained V3 Messages input-history snapshot passes through the source profile; Host/Client typechecks and all 41 documentation gates pass. The generated comparison records four changed roots and 447 unchanged type fingerprints. Latest-master ARIA changes are retained, with producer source labels applied independently; new Messages fixtures retain their producer names as declared source kinds and use the fixed system-message helper; recorded Session generations are unchanged by this regrouping.

Represent tool results as tool-role messages and migrate released wrappers
without losing outer own JSON fields, call identity, error state, or writer
field order. Refuse nested or wrapper-only information that has no lossless
current representation before successor publication.
Validate current event relationships directly instead of projecting V4 data
back into V3. Keep lifecycle, PTC, title/command, compaction, system-field and
retired-syntax checks on catalog restoration and ordinary JSONL opens. The
Worker JSON equality helper must inspect own keys so it cannot admit PTC
arguments that Node rejects.
Keep the source role change, required native admission and consumer fixture
updates in one complete review layer. Explain shared-type changes in the
persistence record and the native reader rationale in its existing note.
Use checked branded fixture identities and discriminant narrowing instead
of unknown double casts; fixture values and assertions remain intact.
This recomposes the original tool-role work by _Kerman with the independently
validated migration and admission repairs by Tianyi Cui. Frozen generations
and snapshot input version selection are retained.

Drop the image/offload event and every session change with it. An adapter's
IMAGE_OFFLOAD_REQUIRED failure now makes dsh-llm-retry replace the surface
nodes carrying the named oldest images with copies whose blocks are marked
offloaded, through the same surfaceOp: replace compaction uses, then retry the
step. ImageBlock.offloaded becomes a durable field the routes project and the
token meter prices; the session core, its event map, derivation, and
validation return to master.
The parent representation fix now correctly invalidates header-based caches with scalar state version3. The dependent in-history projection has a different compact live-surface schema and must not reuse that version. Advance it to4 and prove that a lower-layer version3 cache is discarded and refolded, alongside the existing version2 regression. No historical Session migration or compatibility mechanism is added.
Addresses ds-review-bot cache-version thread3921300994 across the stack. Validation:62 focused projection, adapter and admission tests passed; context.ts and breakdown-projection.ts each have100% exact-source coverage; paired README record updated.
The breakdown refactor correctly stopped consuming scalar shadow claims, but its old negative test was the only coverage of the pressure fold rejection path. Exercise the remaining real pressure consumer with mismatched start and end claims, preserving the runtime invariant rather than deleting or ignoring its guard.
Validation: Linux and Windows CI reported the two uncovered locations in surface-projection.ts. All118 token-meter tests pass and the exact pressure fold file now has100% statement, branch, function and line coverage.
The session projection API can return undefined when a unit is not registered. Assert the registered test fixture produced state before inspecting compact entries, rather than assuming a value that the current master type does not guarantee. This preserves the retained-state regression and adds no production fallback.
Validation: the aggregate build identified three TS2532 errors in this test; all context-breakdown projection cases pass after narrowing. Full build is rerun separately.
Scalar shadow prices cannot restore an earlier effective prompt when compaction removes the newest system node: subtracting that price from messages can permanently make the published bucket negative. Reuse the positional measurement planner over compact current surface entries and choose the last nonempty system by surface order, not event sequence or provenance citations.
Explicitly trade the scalar checkpoint for O(current retained surface) state, dropping shadowed entries and message bodies. Version 3 invalidates old scalar checkpoints; pure transitions preserve wire identity for same-price rewrites. Cover newest/middle removal, reversed sequence ranges, extra sources, empty fallback nodes, replay and late registration, cache version rejection, and route-independent heuristic totals. Document the bounded-state exception and rejected prompt-only ancestry approach in both languages.
Consolidate the existing in-history capability, loop, UI and artifacts into one baseline. Preserve the reviewed tree so each independently verified correction has a subsequent rationale-rich commit.
Address ds-review-bot thread 3921300994 (PRRT_kwDOS3Pfcs6eyLsu). contextBreakdown now folds system/message instead of request/header.system, so version-2 checkpoints have different semantics even though their numeric fields still pass the current schema. Bump the lower projection to stateVersion 3 so cache-only reads omit old values and restore replays the full log; derived caches are not covered by the Session-log persistence compatibility waiver. No migration or fallback is added.
Regression seeds a schema-valid v2 row at the current watermark with stale system/message prices. Before the bump, cache views returned it, restoreFloor selected seq 2 rather than 0, and restore retained system=0/message=17 instead of system=8/message=9. After the bump, the 13-test owning suite passes and exact src/breakdown-projection.ts coverage is 100% statements, branches, functions, and lines; refreshed rows equal a fresh fold at version 3. Existing token-meter README prose documents the current system/message fold without a version literal, so it needs no edit.
Propagation requirement: the upper layer already uses version 3 for a different compact cache representation. Advance that layer to version 4 when propagating this fix to avoid assigning one version to two schemas.
Consolidate the representation-change PR and its rebase reconciliations into one baseline. Preserve the exact tree and keep the in-history feature in the dependent PR. Follow-up fixes remain separate.
Record the image offload point as the core image/offload session event so the
derived surface, every adapter, and the token meter share one offloaded set.
The agent loop plans the advance from the route's declared request-image
budget before dispatch; an adapter whose exact accounting still overflows
fails with IMAGE_OFFLOAD_REQUIRED and the loop advances by the named count.
foldSurfaceTokens rebuilt the priced surface on every surface event: an
append allocated [...nodes, node] and a replacement copied the whole
array before splicing, charging every well-formed event O(surface) for
an atomicity property only malformed events need. Benchmarks put the
copy at ~99.9% of an append's cost (100µs at a 50k-node surface vs
0.1µs for pricing) with O(S²) accumulation over a session, inside the
synchronous session/event publication path.
Split the fold into the session core's planSurfaceEvent/applySurfacePlan
shape: planSurfaceTokens performs every fallible step against the
read-only surface, commitSurfaceTokens applies the plan in place and is
infallible by construction. _foldEvent plans first, runs the remaining
fallible anchor validation, and only then commits, so retry identity is
preserved by ordering instead of by allocation. Appends drop to
amortized O(1) (100.3µs -> 1.9µs at 50k nodes); replacements keep their
O(surface) findIndex but stop paying the extra full copy (21µs -> 4.2µs).
A new regression test pins the one hazard this introduces: an event
whose surface plan is valid but whose later anchor validation throws
must leave the priced surface and running total uncommitted across
repeated failures.
Machine-produced by `pnpm run rescope-vendor --apply` plus the regeneration it
prints: `pnpm install` for the lockfile, `pnpm run gen-third-party-notices`,
`verify-translation-pairing --write` for the touched bilingual pairs,
`gen-doc-graphs`, and one typert snapshot whose ids embed character offsets.
`pnpm run rescope-vendor --check` verifies the result.
Renames nine vendored packages (cordis, cosmokit, schemastery and the six
@cordisjs plugins) and every reference that resolves them: manifest names and
dependency keys, module specifiers including declare-module merges, cordis.yml
plugin names, tsconfig paths, every Markdown fence, and `docs/` prose.
Directory names, upstream versions, and dependency ranges are unchanged, so
vendor/README.md still reads as an upstream snapshot; its manifest table gains
an upstream-name column so THIRD_PARTY_NOTICES keeps MIT attribution pointed
at each fork's origin.
The tutorial tier follows the rename end to end: its yaml fences named plugins
the Loader can no longer resolve, its `ts ignore-check` fences disagreed with
the compiled fences beside them, and its prose quoted both. The contracts that
told readers to keep upstream names — the root convention and the vendoring
cookbook's tree comment and manifest invariant — now say to rescope instead.
Two rules read `@deepseek-ai/` as "another workspace plugin": the client bundle
purity gate now names the vendored libraries a browser bundle inlines, and the
files where a bare `cordis` is an agent-preset id keep that product data.
The contextBreakdown and contextPressure units carried the full priced
surface, so each session's persisted projection checkpoint grew without
bound. A surface replacement is now priced by the shadow-price event
logged directly before it — compact/summary for compaction, the new
compact/prune from tool-result pruning (priced through the injected
token meter) — and the unit states shrink to a fixed handful of numbers.
Regenerate the persistence/cordis/module/config catalogs.
