Clickable artifact links across the transcript (markdown anchors, prose
file mentions, web source/fetch links, produced-file chips, workflow
member links) now share one language: a dedicated --dsw-alias-link color
(light deepseek-500, dark deepseek-400) decoupled from
state-business-primary, font-weight 500, no underline at rest, and a
dotted 3px-offset underline on hover/focus. A new ui-primitives LinkIcon
leads each link with a currentColor category glyph (url / folder / code /
image / document / other) derived from the path extension by
classifyLinkPath. Produced-file chips drop the grey pill and 96px cap and
render at natural width, shrinking with ellipsis only on row overflow.
ToolRow's grey dotted file links and the grey show-in-folder action stay
as they were. The inline-code chip tint moves to neutral-50 (dark
neutral-800) with its 0.5px border kept.
Coverage: LinkIcon unit spec, refreshed markdown-dom fixtures, and the
clickable-links-gallery web e2e registered in the host compiler face.
Closes#3546
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.

`assertFixtureInventory` folds every retained generation of one parent or
child fixture into a single role before comparing, so an older generation kept
beside the current one is not an inventory drift. The generation spec writes
headers that match each filename, since fixture selection validates the chosen
generation, and asserts that an absent parent resolves only for an
override-only replay. The `dsh_session_log` composition expectation follows the
extension's version 2 payload.
The continuable-child headless expectation and the Python `advanced` and
`restart` scenarios pin the current runtime, whose subagent children carry no
`session/end-seed` marker and whose assistant messages embed their streams:
the child fixture drops the marker and renumbers its references, `advanced/`
re-records `result.json`, and both scenarios gain their v2 Session fixtures.
Unit tests cover the `tool-call-delta` id and name validation, embedded
stream members without timing arrays, and the versionless-header refusal.
The JSONL backend rethrows storage errno failures and abort signals from the
source read of a pending migration unwrapped; a test now drives both through
the stat seam so the classification stays covered. The navigation-panes Web
e2e derives the exported archive entry from `SESSION_FORMAT_VERSION`, which
`session-log-export` uses for its `session.v<N>.jsonl` name. The module graph
records the `session-log-export` → `session` peer edge.
Spec files that create /tmp/dsh-* directories via mkdtemp now track and
delete them in afterEach/afterAll; module-scope fixture dirs (executor
spill dirs) are removed in afterAll. The file list came from the
observed-residue inventory on the self-hosted CI host: only specs whose
dirs actually accumulated were leak sources (issue #3134), superseding
the kept-but-unmerged CI sweep branch per the #3233 review decision.
Product per-process spill roots (dsh-subprocess-local spawn,
dsh-spill-local store) register a process-exit handler that removes the
memoized dir, so processes that used the spawn/spill path clean up on
normal exit. A SIGKILLed process cannot run in-process teardown; the
machine-side timer remains the backstop for that path.
