docs(notes): archive low-future-value Agent Notes
...
Run the dsh-archive-agent-notes audit over every active Agent Note on
current master, judging each record by whether its rationale still guides
work rather than by size or age.
- Archive 453 implemented bilingual triplets (417,882 English words):
completed UI chrome, narrow adapters, closed bug fixes, implementation
walkthroughs whose package READMEs, docs pages, generators, or successor
notes now carry the useful behavior, and 51 records fully superseded by
a later active note. Keep 201 implemented notes whose ownership rules,
negative guarantees, durable or wire semantics, security rules,
reintroduction conditions, or still-tempting rejected alternatives
remain useful.
- Reject 7 proposals whose premise is gone or whose work shipped in
amended form under other records; delete 2 rejected notes that no
longer prevent a plausible mistake.
- Retarget every remaining inbound link to the archived path, and repair
active prose that named an archived record as the owner of a live fact:
parenthetical citations drop, ownership sentences redirect to the
README, docs page, or active note that states the fact, and history
citations say so. Chinese files link the English archived path because
the pairing gate treats the frozen tree as outside the bilingual corpus.
- Seal 1,359 new frozen artifacts; existing seals are unchanged and
outbound links from archived notes are neither inspected nor repaired.
- Regenerate docs/config-catalog.md after the hook-bridge comment edits
shifted two source line numbers.

refactor(session-persistence)!: handle-based seam with a lifecycle-owned write path
...
The persistence seam is now create/open/stat/list returning per-session
SessionHandles (read/append/flush/close); every log read and write flows
through the owning handle. The seam package exports only the service and
handle contracts, consumer-visible errors, and pure durable-data
validation helpers; each backend owns its complete storage runtime, and
the shared contract suites pin equivalent observable behavior. The
backend routes published sessions' live events by id into the active
write handle; agent-loop only acquires, seeds, and closes the handle.
Resume appends interruptedTurnClosers through its write handle;
session-query owns the revision-keyed cold cache. Legacy-only surfaces
are removed in the same swap: locate/readRaw/supportsRawArtifacts, the
legacy event-shape read migration, zstd torn-frame salvage,
DSH_SESSION_JSONL, and hook transcript_path population; a torn final
zstd frame is discarded whole; the session-list cold blank probe returns
on stat metadata (eventCount derived from the last physical row,
sizeBytes). The WebUI ZIP export serializes the logical log from a read
handle, so both backends export identically.

refactor(http-proxy): converge the proxy API on four functions
...
The package exported six functions, four of them shaped by one SDK's
transport each: a dispatcher factory, a `node:http` agent factory, a
proxy-URL lookup, and a policy accessor. Review asked whether the call
sites could converge instead of the package growing an export per SDK.
They could, and each removal took a whole shape with it:
- The OTLP exporter moves to the SDK's `fetch` delegate, retiring
`createNodeHttpAgent`. Its Node-version floor goes too: `proxyEnv` on
an `http.Agent` needs 22.21 or 24.5, inside the engines range, so
telemetry was direct on 22.19, 22.20, and 24.0-24.4. The cost is
`compression`, a Node-transport option; the plugin now refuses it,
`keepAlive`, and `httpAgentOptions` at load instead of ignoring them.
- `web-fetch-http` builds its own address-pinning agent under an
annotated `proxy-exempt:` exemption, retiring `createDispatcher`.
Pinning is per-request state a process-wide dispatcher cannot hold.
- E2B reads `route.proxy`, retiring `proxyUrlFor`.
What remains is `installProxyFromEnvironment`, `proxyRouteFor`,
`proxyEnvironmentForChild`, and `clearedProxyEnv` — one per way a caller
can need the policy. Installation absorbs resolution and diagnostic
reporting, which no caller needed apart.
`proxyRouteFor` also closes a defect the old accessor made expressible:
`web-fetch-http` read the policy to decide whether to pin, then read it
again to build a transport, so an unmount between the two returned a
direct, unpinned agent for a URL the first read had cleared as proxied.
A route carries the answer and the transport that answer assumed.
Every egress spec now installs through `installProxyFromEnvironment`, so
no test asserts a policy object a real launch could not produce.
