A non-associative hatch's boundary vertex grips now offer Add Vertex and
Remove Vertex next to Stretch, on polyline boundaries and on boundaries
made of line edges alike. Add Vertex inserts the vertex after the picked
one, halfway along the next segment (on the arc for a bulged polyline
segment, splitting its bulge), and lets it be placed like any grip.
Remove Vertex drops it while keeping at least a triangle.
Line-edge boundaries used to show two grips at every corner (one line's
end, the next one's start), so dragging one opened the loop; each corner
is now one grip that moves both ends.
The automation grip_menu_pick action chooses an entry of the open grip
menu, so these edits can be scripted and checked.

Typing <angle at a point prompt (e.g. <30) now fixes the direction of
the next point from the last one until a point is placed: the cursor
moves along that direction, and a bare number entered next is the
distance along it. The angle is read in the drawing's angle base and
direction and turned into the current UCS. Works from the command line
and from scripts or the automation token input alike.

Host side of HostApi::set_reference_only: plugin-owned display geometry that
renders and snaps normally but must not be edited or picked by the person at
the screen, while the owning plugin keeps full write access through the host.
- Storage: a human-readable marker value in an XDATA record under the
host-owned OCS APPID (registered on first use; foreign values survive
verbatim; stale verbatim DWG EED is dropped on rewrite), so the flag
round-trips DWG and DXF with the entity and cannot collide with plugin
APPID namespaces.
- Grips: refresh_selected_grips yields none for a reference-only entity and
an active grip edit on a newly designated target is cancelled like a
locked-layer one.
- Picking: a reference-only wire flag extends the snap_only skips in every
hit test, so a click passes through to the editable entity underneath, and
box, window, lasso, fence and select-all gathers skip the designation;
fills, solids and instanced meshes are excluded through the shared
candidate handle set.
- Write policy: built-in user paths treat a reference-only entity like a
locked-layer one (Scene::update_entity / update_entities refuse,
erase_entities skips), while the plugin-owned variants
(update_entity_plugin / erase_entities_plugin, mirroring the
remove_entities editor split) and the whole HostSession surface write
through. The MCP entities read exposes a top-level reference_only boolean
and set_properties refuses with the reference_only failure code.
- Undo: the entity-write contract - a change joins a plugin-opened push_undo
scope, a scope-less change is one undo step of its own, refusals and
idempotent re-marks record nothing.
- Known limit: entities nested inside block instances (the block cache
rebuilds instance wires without the flag).

foreign_values_under_the_host_app_id_survive, other_apps_are_untouched,

Introduce would_create_cycle in block_service to prevent recursive block definitions with case-insensitive matching across block records. Enforce cycle refusal at INSERT commit in BEDIT and during block redefinition (redefine_block_raw) with a shared error message. Ensure render-time recursion truncates safely with a one-time session warning on cyclic documents.
Enforce constant attribute flag in ATTEDIT dialog by presenting constant attributes as disabled and ignoring modifications. When exploding an insert, restore block-definition attribute definitions as transformed ATTDEF entities while dropping instance attribute values.
In a tilted 3D view a grip followed the cursor onto the screen plane
through the orbit target, so a circle or arc jumped to another radius and
a polyline vertex left its plane. A model-space grip now moves in the UCS
XY plane at its own elevation (the screen plane only when seen edge-on).
A solid stays drawn while its grip moves, and its own edges were still
snap candidates: a cone's base radius landed on its own side. The edited
entities are left out of the grip's snap set.

The new pointer op sends moves (canvas pixels, or a world point projected
through the camera the cursor edits with), button presses/releases and
wheel steps in order, and reports the cursor's world point after each, so
grip drags and picks go through the same cursor path as the mouse.
click now projects through that editing camera too (it used the model
camera inside an entered viewport), and the grips read reports each
grip's constraint axis.

- A layout opens for the first time when its page setup was never
initialized (no paper size, no media name) or it was created in this
session; its page setup is initialized then, and with
LAYOUTCREATEVIEWPORT it gets its first viewport. A layout never opened
is saved with an uninitialized page setup and no viewports, so it gets
its viewport when the file is opened again, here or in the reference.
- Select Viewport for view: a viewport is selected when the pick box
(PICKBOX pixels at the sheet's zoom) touches its frame; a pick well
inside or outside selects nothing and the prompt repeats.

A new drawing is metric with metre insertion units, but its annotation
multiplier stayed at Scene::new()'s unitless 1 while opened files and
CANNOSCALE convert paper millimetres into drawing units (0.001 at 1:1).
Annotative text and dimensions were drawn 1000x too large until the
first scale change, then shrank to their real size and looked gone,
also after switching back to 1:1.
One helper now derives the multiplier from the header; new drawings,
file open and every INSUNITS change (UNITS, the units popup, DWGUNITS,
SETVAR) go through it.

- Layouts: a model-space view restored on a sheet asks for the viewport,
enters it and gives it the view's camera, background and visual style;
inside a viewport the view goes there; a paper-space view's background is
kept on the sheet viewport but not drawn; floating viewports draw their
background.
- Background objects no view or viewport uses any more are erased; a view
without a background restored where the viewport already is leaves the
viewport's background.

HostSession::update_entity, update_entities_transaction and remove_entity mutate entities and republish the document view, but never rebuild the app-side selection caches the way the built-in edit paths do. A selected entity updated by a plugin kept its cached grip markers at their pre-edit positions until the next real selection event; regen did not help and HostApi::set_selection cannot work around it (it bypasses the grip cache).
Refresh the grip cache for the session tab after a successful update_entity / update_entities_transaction / remove_entity, mirroring the built-in ERASE path and the other editors, so a plugin-driven edit keeps the cached grips on the refreshed geometry. A session targeting a background tab leaves the active tab cache untouched (found by the civil plugin manual QA, 2026-10-12).
Ported from da950460 (#1717).
In-place save:
- A stale retained handle could receive bytes serialized for a
DIFFERENT format (Save As .dwg->.dxf whose re-pick failed wrote DXF
bytes through the .dwg handle) or silently save in place while the
user was told a copy was downloading. The serialized format now
travels to completion (tab-keyed pending map), the write requires a
matching handle extension AND a live tab, and a failed re-pick
drops the old handle before the download fallback.
- Discarding an unsaved tab leaked its handle, and a serialization
still in flight could then overwrite the real file the user just
declined to save. Discard drops the handle; a tab-gone completion
downloads instead of writing.
- Overlapping saves had no guard: a wasm in-flight slot refuses a
second save with the same localized message, cleared on every exit
path.
Paste: pasted_image_name built its timestamp from Date::new(0) — a
CONSTANT name, so every paste overwrote every earlier paste's image.
Real clock, milliseconds, and a collision-suffixed unique name now.
Capture: a web capture in a hidden tab, or one with nothing redrawing,
could hold the automation slot forever. It fails fast when the page is
hidden and gives up after 5 s, on main's frame-parked capture.
The XREF manager reports registry-loaded xrefs with their size on the
web instead of NotFound.
Left out: the always-warm print snapshot (a frames subscription that
emits a message on every frame keeps the app redrawing at the display
rate), so the browser-menu print wiring from the previous commit goes
too — its beforeprint readback printed blank pages on WebGL2. The
merge-residue hunks (re-added XREF bind tests, snap endpoint map and
3D-snap gate) belong to code main already has in its own form.
(cherry picked from commit da950460)
The last high-severity web gap plus a small integration bundle.
In-place save: with the File System Access API (Chromium/Edge), Save
now works like desktop. Plain Save on a tab with a retained handle
writes straight through — no picker, no download, no "(1)" copies.
First save or format change opens showSaveFilePicker AT the confirm
gesture (the worker serialization that follows can outlast the
transient-activation window; retained handles need no activation to
write). Picker cancel cancels the save like desktop; picker or write
failure falls back to the legacy download with a note; Firefox/Safari
keep the download flow untouched (feature-detected). Handles are
keyed by tab id in a thread-local registry (Message must be Send —
JsValue cannot ride in messages or App state); closing a tab drops
its handle; Save As re-picks. Dirty clears only on successful
persistence, same race guard as before.
Image paste: Ctrl+V of a screenshot inserts it as an image reference
— the clipboard reader falls back to image/* items when neither the
entity clipboard nor text has anything (precedence preserved), the
bytes enter the image source registry as pasted-<timestamp>.<ext>,
and attach reuses the IMAGE command's model-creation path verbatim.
Browser print: beforeprint snapshots the WebGL canvas into a print-
only <img> (the capture_canvas technique), so the browser's own print
menu produces the drawing instead of a blank page.
Automation capture on web: the capture op no longer calls the
synchronous GPU-map screenshot (dead on wasm); main's frame-parked
capture waits for a presented frame and reads via capture_canvas — the
same workaround the save-thumbnail path uses — delivering the PNG as a
download.
(cherry picked from commit 6e89b36d)
Ported onto main (#1717 review): the web capture rides main's existing
frame-parked capture (one ControlCaptureFrame path, ignoring the timer
tick on wasm) instead of a second parked-capture state; closing a tab
drops its file handle inside main's on_tab_close.
Two reviewers, no blockers, two majors — all fixed.
- The remembered-tab focus after a Restore-all batch fired at the
message boundary, but the LAST restore's tab inserts one async round
later (its OPFS recent-cache write precedes the insertion) and the
insertion's own activation overwrote the selection. The focus flag
now also consumes at the insertion point, so the batch focus holds
in the common all-success case.
- The service worker cached ANY successful in-scope navigation under
the shell key — a direct navigation to a font or JSON would be
served as the app shell for every offline navigation until the next
online visit. Only the scope root caches as the shell now.
Also: '/app/' gets its own web app manifest (the previous commit's
'installable' claim was true only of the marketing site, whose
start_url sits OUTSIDE the service worker's scope — an installed app
opened offline showed an error page). Its icon is the
existing assets/logo.svg, copied next to the page.
(cherry picked from commit 369e2c8b)
Ported onto main (#1717 review): the build-web.sh and README hunks stay
out with the wrapper.
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 Pages workflow stamps the cache version from the bundle hash and
fails if sw.js is missing or unstamped.
(cherry picked from commit 5f9b345e)
Ported onto main (#1717 review): the cache-version stamp moved from the
skipped build-web.sh wrapper into the Pages workflow; the tab-close hook
lands in main's on_tab_close, which also cancels pinned control requests.
Ported from d719fb77 (#1717); the hatch draw-order, PDF and
recovery-settle hunks stay out (main owns those paths).
- La16 was still billed at 4 B/px: the no-conversion special case
keyed on native_bpp == 4, which La16 also is — but only Rgba8 is a
real move in into_rgba8, so La16's decode peak is 8. The case now
keys on the color type, and a table test pins every layout's peak
(plus GIF's screen+frame 8) so the accounting can't silently drift.
- json_values_match: an integer beyond f64 precision no longer matches
a float it merely rounds onto; a mixed pair matches only when the
float is whole and converts back to exactly that integer (also the
fuzz finding of 9262d63f).
- ocs-control.js resolves `ready` with the API object instead of
window.ocsControl, which is still undefined when the bridge already
exists as the script runs (built before the first settle, avoiding
the temporal-dead-zone throw of a later const); DATALINK on web says
the typed path is superseded by the picker instead of silently
discarding it.
(cherry picked from commit d719fb77)
Ported from 2c38de53 (#1717). Main already carries the hatch PDF draw
order fix (#1345), the numeric set_properties compare (#1348) and the
web open from bytes, so those parts stay out; what remains:
#1349 — window.ocsControl.ready/request promise wrapper with an
ocs-ready event (web/ocs-control.js, loaded by the web page), and the
startup donation prompt is suppressed once a control request is seen
(opt-in pre-boot via localStorage["opencadstudio.automation"] = "1").
docs/automation/web.md documents both. The control protocol stays at 1.
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.
