Tests bring the changed sources to full per-file coverage, the READMEs and
docs describe the uplink, the invocation context, and the Peer registry in
both languages, and the generated catalogs are refreshed.
Every Typert Remote stream accepts client-to-Host items on the same
logical stream. A method declares the uplink item type in its return
type, RemoteStream<Out, In>, and reads the items through
this.ctx.invocation.uplink(); the invocation also carries the calling
Peer. Client generated methods return a handle that iterates the
downlink and exposes send/end/dispose for the uplink.
Address review: retention now has a single definition (retainedIds) shared by
the list-refresh sweep and the single-id prune, an already-engaged identity
skips the redundant row mutation, and the ledger documents why Host-asserted
running is recorded before any holder exists while the client-local acceptance
callback requires one.
The cold row's updatedAt is the later of the header's creation time and the cached last prompt; the fork's creation time is wall-clock and can trail the inherited prompt by a millisecond, so the restart test asserts the same maximum instead of the prompt time alone.
A real fork made through sessions.fork is checkpointed into the projection cache, the Context is disposed, and a Host booted over the same storage root serves the fork's title and list metadata from the header alone, as a kind: 'cached' block, without inspecting or opening the log.
The session-controller README, the per-session store JSDoc, and the projcache predecessor-recovery and durable-web-queue-recovery notes described one higher-seq-wins rule and the asOfSeq -1 title hint. They now state that higher-seq-wins applies among Host-sequenced values, that cached list blocks yield to the connected Session's baseline, and that the predecessor title carries its stored row's watermark under kind: 'cached'.
A `sequenced` list block merges key by key under higher-seq-wins like any Host-computed value, so a delayed control baseline at a lower cut can neither overwrite nor clear a newer live-session list value. Only a `cached` block goes through applyCached and yields to every sequenced write. The projection store's module docs describe the two row kinds.
SessionProjectionHints gains a required `kind`: `sequenced` when the Host's live registry computed the block for an attached Session, `cached` when a header-only listing viewed it from the persisted projection cache. `asOfSeq` stays the producer's own watermark in that space, so the cache read faces report the lowest served row seq again instead of the -1 sentinel. The two fields are independent: `kind` names the sequence space, `asOfSeq` the position in it.
ProjectionValueStore rows are either cached (viewed from the persisted checkpoint by the session list, no comparable seq) or sequenced (computed by the connected Host, seq comparable within the connection). Cached values fill empty keys only; every baseline discards cached rows before seeding, and every frame replaces them regardless of seq, so a connected Session's values always supersede list hints. The list response and api-session/added blocks write cached rows.
The projection cache read-only face (cachedSnapshot, cachedPredecessorTitle) now matches the lifecycle identity a header witnesses (formatVersion, createdAt, cwd, isSeeded) and serves its rows as a cached block with asOfSeq -1. The fold face (hydratePrepared, write, coldSnapshot) keeps the full identity including the inherited cut. The session list and @ completion drop their isSeeded guards, so forked sessions keep their cached title and list metadata across a Host restart; list-children keeps its body fallback.
Attachment reads and ZIP export previously inferred ownership from common
field names on arbitrary events. Opaque ignorable plugin payloads could
therefore cause storage reads, while declared compaction content was missed.
Select attachment-bearing fields by current built-in event type in both
readers. Read direct image and file blocks, including flat V4 tool results
and developer messages, without interpreting extra block fields. Leave
unknown payloads and malformed inbox entries opaque. The archive preserves
the complete logical log even when its payload does not authorize a read.
V4 validates title requests as one text block, so do not treat them as an
attachment carrier. Compaction keeps its declared ContentBlock fields for
valid custom producers; the basic producer's text-only output is documented.
Historical wrappers remain the adjacent converters' responsibility rather
than a second compatibility path in attachment readers.
Adapt the original policy change to master after V4 landed, retaining its
author credit and scope. Cover tool-result export explicitly, keep Team
fixtures free of invented message roles, and verify that denied carriers
never read storage. The 889 owning tests pass with 100% statement, branch,
function, and line coverage for both changed runtime files.

The event-type allowlist and opaque-payload attachment policy change live
Session authorization/export behavior independently of a format upgrade.
They belong in a focused PR against master, where supported native V3 nested
tool-result content must also be handled deliberately.
Restore the session-controller and archive implementation, tests and README
pairs to this layer's parent. Remove the test-only session-format-catalog
dependency and its lock entry with the migration-specific attachment tests.
The original changes are captured from immutable commit 85737364be9 for the
standalone work; migration identifier conversion and reader checks are intact.
This extraction keeps the integration stack's existing attachment behavior
until the separate policy change is reviewed. It makes no Session-format,
schema or version change.
V3 permits external event, source and content identities and additional
request-tool fields. Copying those values into V4 can give an old plugin
named tool a core source identity, turn old tool-addition content into a
registry instruction, or activate formerly ignored deferLoading and delivery
metadata. Rejecting such collisions would instead refuse valid source logs.
Keep historical extensions in the existing extensible JSON representation.
Prefix unknown content and ignorable event tags with plugin:, preserving
all other content fields and opaque event payloads. Prefix external source
identities with plugin:plugin: or plugin:source: so wrapper and direct kinds
cannot collide even when original names already contain a category prefix.
Known first-party mappings remain explicit and unchanged.
Prefix extra request-tool field names and block-start field names with
plugin:, retaining exact values and existing-prefix doubling. Core schema
parameters, arguments, replay state and nested plugin data are not traversed.
Keep future-generation delivery records inactive after header promotion.
Pin the V3 event vocabulary independently of the current writer and provide
an offline verifier against an explicitly selected historical source commit.
Attachment authorization and export inspect declared event content only.
Team checkpoints preserve all own keys of unknown JSON blocks while still
rejecting malformed known content and retired core tool-result blocks.
Exercise physical read/write/reopen, prefix injectivity, own __proto__ keys,
provider opacity and retained source-identity snapshots.
No generic extension block, metadata wrapper or new schema-tooling type is
introduced. V4 type declarations, persistence schema, checkpoint and frozen
V0-V3 codecs remain unchanged. Canonical tool-result lifting and incomplete
child-catalog policy remain separate concerns.

Merge master 7e2b049d8e2523127a3b4fba38cab4748ef0c72f, observed on
2026-09-19 at 07:38:37 UTC, into release/session-log-v4 at
c4663e8671e33bc2cfdbc868b0b18d979508d39b. Keep this base integration
separate from the five persistence repair PRs so their review diffs
remain focused and can be rebased without moving their fixes here.
Combine master's pin ordering and archived-session filter with V4's
parent-owned direct child catalog. Both grouped and flat sidebar rows
must pass the Session list to the V4 activity calculation; restoring
master's summary-lineage traversal would reintroduce the removed
subagent ownership and count unrelated descendants.
Keep master's removal of the archived-session settings page. Its only
release-side test change renamed a Session list fixture field, so no
runtime behavior is lost by deleting that obsolete test. Adapt the
release-side direct-child-status regression to the new row/filter
arguments and preserve its assertions.
Retain master's workspace ordering and row-motion documentation while
keeping the V4 child-catalog wording. Reconcile the generated bilingual
records against the merged documents. Frozen V0-V3 codecs, recorded
Session JSONL inputs, and the current V4 persistence schema are unchanged.
Refs #2692, #3273
Pin sessions to the top of the sidebar and reach archived sessions
through the view-options filter instead of a settings page; archiving
gains an undo/filter toast, and row motion stays reserved for pin jumps
and archive fades.
Keep the master refresh separate from the V3-to-V4 lossless-conversion and
checkpoint JSON fixes so the release baseline and each feature change remain
independently reviewable. This checkpoint extends the already-published
4435f6f519 merge before the #4583 child is rebased.
Integrate exactly master 5ec3ffe337062ab5bb4955933008afe8d0a0b915. Its #4156
changes add watched file/document refresh, filesystem watch readiness,
directory expansion restoration, and chat bottom-follow fixes. They update
shared filesystem and Client consumers without changing Session format or
snapshot generation.
The merge has no conflicts. Its 114-file scope and line counts match upstream;
code and prose additions/removals are unchanged. Only the two translation
pairing records incorporate the release branch's retained V4 documentation.
Validation: 762 owner tests passed (1 platform skip), 11 focused Web tests
passed, full build passed, and all 41 doc-sync checks passed. Runtime closure
and Client package checks passed; fs-local publint completed with the existing
source-wildcard export warning.
Merge master 0e9385ad8b9e75146f4baec2e731dd961f11c87c, observed when
this final integration step started, into the merged V4 release branch.
Keep the complete upstream history and do not advance to later master
commits during finalization.
Bring the Web trust-domain and relative-route handling, plugin install
cancellation, and npm registry mirror configuration into the common
release baseline. Retain the V4 codecs, producer-source policy,
parent-owned catalogs, and fork/migration behavior from the merged stack.
The merge needs no manual conflict resolution and changes no Session
JSONL inputs, snapshot generations, format packages, or persistence
schema/history files. This checkpoint precedes the separate V4 freeze
and audit fixes so each change keeps its own rationale and validation.
Session V4 reserves developer-role messages for incremental model-visible
session changes. The role, tool addition/removal blocks, and deferred-loading
marker need a durable representation before independent provider and UI
integrations can emit or consume them. Known developer events must match an
open turn and step; unsupported providers and UI consumers fail explicitly.
Request headers already capture full tool definitions. Persisting another
ToolSchema in each addition would duplicate Session information and create
two definitions that could drift. Additions therefore store toolName, and
the containing developer event uses headerSeq to select one earlier known
request/header for all its additions. A same-name replacement keeps its
historical definition identity through restart, fork and surface changes.
Removals require no definition copy, and ordinary developer messages omit
headerSeq. Generic sourceEventSeqs remains independent derivation metadata.
The rejected inline tool field is optional never with @persistenceReserved.
The schema extractor retains that uninhabited slot, so permitting a future
value requires a format bump instead of being mistaken for compatible
optional metadata. Unrelated optional fields remain additive and readable.
Native and Session admission reject missing, forward, non-header, unknown,
ambiguous and incomplete referenced definitions, and reject the retired
inline tool field. Validate complete schema fields only for referenced
definitions, preserving unrelated header behavior and extra JSON metadata.
Unknown ignorable records remain opaque. Empty developer nodes retain their
surface position without producing a message or shadowing the system head.
No automatic emitter, provider activation, UI implementation, or speculative
public resolver is added.
Keep the core-owned developer source binding beside the introduced role,
including the request-only type rejection and attribution round trips. Update
consumer guards, SDK/snapshot handling, bilingual owner documentation, and
the same unreleased V4 acknowledgement. Keep earlier tool/source migration
work and its documentation in the parent. Preserve the existing recorded
Cordis inspection generation from the original developer change.
Integration keeps the final source layer as the sole parent and preserves
master's Messages input filtering, empty-user omission, empty tool results,
and system-update placement. Developer/deferred guards still run before
conversion. Native V4 admission, header references, reservation declarations,
and generic tooling match the validated marker candidate. Parent-owned
fixture and generator fixes remain in the parent.
Earlier feature validation passed full build, full lint, 41 doc-sync gates,
and 16 hygiene gates. The unchanged native implementation retains that evidence.
The focused Session/V4/request-input run passes 884 tests across 38 files with
100% statement, branch, function and line coverage for the V3-to-V4 package
and Session surface. Consumer tests pass 482 with one existing skip; tool,
message and optional-field tests pass 146. Cordis inspection and compaction
replays pass in both source and built modes (two cases per mode). Ten invalid
referenced-definition/unknown-header controls failed before their scoped
guards and pass after them.
Reservation validation: the actual generated developer root records tool as
optional primitive never. Widening it requires a bump, while traceId remains
additive and preserved; all 85 focused reader/classifier tests pass.
Final-parent validation: 205 tests across eight provider, type, catalog,
Session and native-format files pass. The preserved parent fixture verifies
Messages input-history replay; runtime/declaration and parent-owned-file
comparisons show no loss during the final rebase.

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.

Merge master 01d96c168a84227374e3aa741e94ddfbb498e27e, observed when
this integration started, after the published 6de3db41 checkpoint. Keep
master's author history and preserve the release writer, adjacent
migrations, historical Session generations, and parent-owned catalogs.
Combine blank Session writer acquisition and superseded-startup
cancellation with the release branch's projection refresh and panel
preservation. A startup acquisition may finish after a later navigation,
but must not retain a stale main Session or reveal its Conversation.
Update the existing regression's retention expectation while preserving
its panel and active-navigation assertions.
Keep the release catalog loading, known-leaf, and parent availability
behavior alongside master's completed-turn status and aligned sidebar
icons. Regenerate the config locations and pair the combined README
contracts. Preserve upstream's Linux process-state assertion repair.
* fix(session): keep blank session discovery local to each host
* fix(session): acquire blank writers before reusing sessions
* refactor(workspace): separate saved selection restoration from blank lookup
* fix(workspace): create after the selected blank writer is held
* test(web): align blank reload snapshot with current icons
Merge a2acc7d3eb620bb52f09f7ea3b5a3a1c23353e18 after preserving the earlier
master checkpoint and its successful CI. Carry current provider input-history
handling, UI controls, agent targeting, and runner-concurrency changes into
the integration base without changing the Session migration feature layers.
Keep durable direct-child catalog semantics alongside the upstream running /
inactive vocabulary. Resolve the snapshot description conflicts by retaining
that upstream status text and the existing descendants-only diagnostic rule;
the source and all 53 JSON tool descriptions agree. Preserve parent-session
availability handling with the upstream stale-blank and batched-history fixes.
The merged application builds, all 41 documentation gates pass, and focused
provider, tool-control, and Session Controller tests pass (98, 29, and 125).
Recorded input changes come from master: one refreshed v3 list-agents sample
and three new v3 scenarios; no migration bumps an existing snapshot generation.
