CI's snapshots lane timed out waiting for the folderx candidate: the
fixture directory was created after connectFreshWorkspace, racing the
Host's file index on a loaded runner. Land every fixture (and the
workspace directory itself) before the connect, and give the first
folder query a cold-start allowance.
A directory row in the @ menu had one verb doing two jobs: picking it
inserted literal @dir/ text and kept the menu open, so a user wanting
the folder itself never got a settled entity — the token kept its
trigger character and stayed editable, nothing like a file's atomic
chip.
Split the intents on the same row, mapped to shell-completion instincts:
row click / Enter settles the directory as an atomic folder chip (the
file chip's exact language; canonical @dir/ mention as its serialized
form — the { insert } arm the folder path never took), while Tab or the
row's trailing chevron drills: literal editable text, menu open on the
children. One new dimension carries it: candidate.drill advertises the
verb, InputTriggerPick.action reports it, ArbitrateKey gains 'tab', and
the keymap intercepts Tab only while a drill row is highlighted.
Covered by controller arbitration, MenuView chevron routing, the
ui-reference verb split, a keymap Tab-passthrough spec, and a real-
browser e2e driving all three gestures; menu golden refreshed for the
chevron and the fixture directory.
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.
- The base-mounted projection cache's write-behind forces session-log
flushes at cache-chosen times, splitting packed chunk rows and collapsing
the persistence window the keyless acp transcripts pin. ACP exposes no
session-listing surface, so the automation profile disables the base row,
restoring the pre-base behavior the fixtures were recorded against.
- The windows coverage lane runs suites that read built lib/ output (the
webworker-packer image tests) and raced the build gate's tsdown writes
against a partial tree; every coverage gate now waits for the build gate.
Delete the 5-bit colour-count classifier and palette PNG branch that
misrouted high-frequency photographic JPEGs (issue #2885 images 23/24)
into an encoder 100x slower with 4x larger output. Both normalization
and request-image encoding now route by the decoded alpha fact alone:
opaque sources down a JPEG ladder and alpha sources down a WebP
effort-0 ladder, each at qualities 85/75/60. Byte budgets become ladder
targets: the downscale retry loop is gone and a ladder-exhausted encode
keeps its smallest output, while provider byte caps stay enforced at
the transmitting route. Request transforms move to request-image-v5.
The exact-shape fix added two filesystem-failure catch branches that only
fire on a race/permission fault the caller already guards against (the
session-dir readdir after an isDirectory() check, and the discovered-root
rmdir after the root was observed empty). Neither is deterministically
reproducible in-process, so tag both with the same reasoned v8 ignore the
sibling catch blocks already use, restoring per-file 100% coverage and the
symmetry between the parallel rmdir handlers.
Tighten the startup sweep to backend-generated name shapes and fix the tests
that had drifted from the SweepRoot-based API:
- Match roots by the exact `dsh-spill-<6>` mkdtemp shape and session dirs by
`session-<12 hex>` (DEFAULT_ROOT_RE / SESSION_DIR_RE), replacing loose
startsWith checks so foreign or fixture-shaped directories are never swept.
- Carry `SweepRoot { path, pruneWhenEmpty }` through SweepOptions so a discovered
prior-default root is removed once emptied while the active root is never
pruned; lstat each session entry so a symlinked session dir is not followed.
- Fix the tests to the SweepRoot API: import SweepRoot, correct the gatherRoots
override return shapes, build discovery fixtures with the real mkdtemp shape,
and route the warn-wiring test through a deterministic failure path.
The local spill backend never reclaimed its files, so configured roots
grew without bound and default per-process dsh-spill-* temp roots piled
up across runs. Immediate deletion is unsafe because persisted, resumed,
and forked sessions may still reference an older locator.
Add a fiber-owned, best-effort sweep that runs once after activation
(never delaying availability, awaited on disposal): it deletes regular
files older than cleanupPeriodDays (default 30; 0 disables) across the
configured root and prior default temp roots, prunes emptied dirs, and
skips symlinks/unknown entries. Every filesystem failure is contained
and logged, so the sweep cannot fail activation or a concurrent write.
preview-boot's hero wait was master's new textarea:enabled locator (the
conv refactor predates the Lexical composer); migrate it to the
data-composer-input surface like every other lane. Drop the unnecessary
DOMRect assertion oxlint flagged on the new Range stub.
- user-text.tsx enters ui-primitives' per-file 100% gate: replace three
regex-guaranteed impossible ?? fallbacks with asserted captures, make
the precedence sort a branch-free rank comparator, and pin the nested
recall-label ordering and the no-basename quoted-path fallback with
tests (100% statements/branches/functions locally).
- assembled-boot stubs Range.prototype.getBoundingClientRect: jsdom has
no Range geometry, and Lexical's selection reveal now reaches it in the
built-graph lane after the architecture merge (the unhandled TypeError
behind command-image-envelope and preview-boot).
