Session recovery: more than one pending snapshot adds a 'Restore all'
button to the Recover Drawing modal — every snapshot goes through the
exact same guarded path as a single restore (deleted only after its
own open succeeds). The open-tab list and active tab persist to
localStorage on web (open/save/close) and the remembered tab is
re-selected once a restore batch settles; the modal notes how many
drawings the session had. Nothing is auto-opened.
Deep links: ?file=<url|name> opens a drawing at boot. http(s) URLs
must end in .dwg/.dxf and are fetched with the same streaming,
64 MB-capped, 8 s-deadline reader the remote images use, then go
through the guarded open queue; cross-origin opens announce the
origin first. Bare names resolve from the browser's recent storage,
with a hint when absent. Everything else (file:, javascript:, drive
letters, non-drawing tails) is refused with a console note.
Offline PWA: the app was installable (manifest) but downloaded its
55 MB bundle on every visit. A cache-first service worker now serves
the whole bundle from Cache Storage after one online visit —
navigations network-first so updates land, hashed assets
stale-while-revalidate, non-GET/cross-origin passthrough, old caches
cleaned on activate, and the waiting-worker update flow documented.
The build wrapper stamps the cache version from the bundle hash and
hard-fails if sw.js is missing or unstamped.
Also fixes a locale group mismatch on the DATALINK pick notice
(catalog said a display group that does not exist in the ftl
sources).
Upstream issues, fixed:
#1345 — hatches plotted at draw_depth 0.0: the plot path cloned models
from the hatch cache, which bakes the depth at seed time; the canvas
re-reads the live depth map every frame, which is why the editor was
right and every export (PDF and native printing — both route through
the exporter) was wrong, with hatch-vs-hatch ties broken by HashMap
order. The plot path now re-reads the depth map per entity, and the
exporter's tie-break ranks follow the editor's own pass order
(hatch < image < wire fill < wire < text < wipeout) instead of pinning
hatches between fills and wires. Pinned by content-stream operator-
order tests (back/front hatches, overlapping hatches, interleaved
wire-between-hatches) and a scene test that fails pre-fix.
#1348 — set_properties' optimistic-concurrency compare now matches
numbers by value (10.0 == 10) through json_values_match, compatible
with the shape of upstream PR #1350; nested objects/arrays recurse.
#1349 — web automation contract: control protocol 2 (v1 clients still
accepted) adds {op:'open', name, data_base64} routed through the
guarded open queue; window.ocsControl.ready/request promise wrapper
with an ocs-ready event (web/ocs-control.js); the startup donation
prompt is suppressed once a control request is seen (opt-in pre-boot
via localStorage); docs/automation documents the whole web contract.
Also: DATALINK CSV-to-table works on web (picker + bytes through the
session registry — was std::fs, silently dead); COLORSCHEME accepts
System (prefers-color-scheme on web, AppsUseLightTheme on Windows).
Decode accounting, made honest per the fix-of-fix review: into_rgba8
allocates the RGBA destination while the native buffer is alive for
every non-Rgba8 layout (L8 5, La8 6, Rgb8 7, L16 6, La16 8 B/px
peaks — the formula now says so), GIF bills the screen+frame
coexistence at 8 B/px, and TIFF drops the 3x multipliers both ways —
tiff 0.11 splits the given budget between frame and scratch (a total
ceiling), so the old double-billing refused honest 16-bit GeoTIFFs
~2.25x early while admitting hostile chunk transients at 3x. The
image-refusal-unknown-size locale key moves to the group the catalog
always claimed (file).
