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.
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.
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.

Write handles now hold a durable lease (session.lock.json beside the
log): a random owner token, diagnostic pid, and an expiry. Acquisition
wins by exclusive create; a second process's create or write open rejects
while the record is unrenewed for less than leaseTtlMs (default 5 min),
and takes over after that — a crashed holder is waited out, never
reclaimed by pid. The holder renews every leaseRenewIntervalMs (default
4 min); a renewal that finds a foreign, vanished, or expired record — or
fails outright — marks the lease lost permanently, so every later
append/flush rejects with SessionOwnershipLostError while reads continue.
Close releases the record; read handles never touch it. Takeover of an
expired record is eventually exclusive: a replaced holder stops within
one renewal interval.
