Priority worked like a rank (lower first) with a default of 0, and the
Edit Drawing form stopped at 0, so moving one part ahead of the rest
meant renumbering every other drawing. Higher-first lets a user raise a
single part to 1 and leave everything else at the default.
Every engine, filler and candidate comparer now serves the highest tier
first. Stored values keep their order:
- .nest files add `nestPriority` and keep writing the negated value under
`priority`, so older readers nest in the same order; files without
`nestPriority` are negated on read. Drawing packages strip both, so
package hashes are unchanged.
- Library settings send both keys the same way for older clients.
- Server schema v18 negates stored drawing priorities (an older server
refuses the upgraded database).
- Job documents move to version 2; version 1 jobs are converted, and an
older worker refuses version 2 instead of reversing the order.
The Edit Drawing form now accepts negative priorities and says higher
numbers nest first.

A server Auto Nest result could only be reviewed in the session that sent it,
and nothing stopped two desktops from keeping the same result. Phase 3 adds
My Server Jobs, so results that finished while OpenNest was closed are easy
to find, and records each review on the server.
- Server: GET /api/nest-jobs lists jobs newest first with state, engine,
submitter, times, queue position, review and the worker's summary (parts,
sheets, utilization, unplaced). It filters to active, finished or
unreviewed jobs and to a submitter (a bare user name matches that user on
any workstation). An ETag turns unchanged polls into 304s. Schema v17 adds
nestId, review and summary columns, only where missing.
- Keep once: POST .../keep and .../discard take If-Match on the job revision
and change an unreviewed result only once. A second desktop gets 409 with
who kept it. DELETE removes finished jobs. A succeeded job keeps its
package until it is reviewed, so a later session can rebuild the job.
- Retention: OPENNEST_JOB_RETENTION_DAYS (default 7) deletes finished jobs
with their results. It runs on claims and list reads. A malformed value
fails startup instead of deleting results early.
- Worker: reports the result's summary with the transcript. A job cancelled
while its result arrived keeps no summary (found in the Docker smoke run).
- Desktop: Nest > My Server Jobs polls the list every 3 s; polling rather
than per-job SSE because the list must show other desktops' jobs and
removals. Open rebuilds the job from job.json against the open nest's own
drawings. New per-drawing geometry fingerprints make the freshness check
work across sessions. Cancel Job and Remove act on the selected job. A
status-bar item counts this user's results waiting for review; there is
no popup. Auto Nest's review now records Keep on the server before it
commits, and records Discard too.

Large nests tie up the workstation that runs them. In Database mode, Auto Nest
can now queue the job on the nest server, where a worker container solves one
job at a time under its own CPU and memory limits. The job has no time limit,
so a throttled worker finds the same nest a fast one does, only later.
- Server: /api/nest-jobs queue (schema v15). The worker holds a job on a
heartbeat lease. When the lease lapses, the job goes back to the queue,
or fails after three attempts. Only one job runs at a time. Packages and
results are opaque to the HTTP server, which stays off Engine and IO.
- Worker: OpenNest.Server.Worker in the same image (OPENNEST_ROLE=worker),
reaching the server over HTTP only. It records each engine answer with
RecordingNestingEngine and gives its job back on shutdown.
- Desktop: "Nest on the server" in the Auto Nest dialog, for built-in
engines only. The client replays the recorded answers with
RemoteNestSubmission, so validation, the review and Keep run locally
against the client's own drawings, exactly as after a local run. A
drawing edited after sending refuses the result. If the server cannot
take the job, the user may nest locally instead.
- compose.server.yaml adds the throttled worker service. The Dockerfile,
.dockerignore, CI paths and the deploy script now include the worker's
projects.

NestPipelineResult.Unplaced lists each requirement's unplaced copies with a
typed NestUnplacedReason, counted from the returned placements: no stock fits
at the sampled rotations, reserved in a cutout of an unplaced frame, stock
exhausted, plate limit, no position found, or proposal not keepable. Desktop
Auto Nest, Console --autonest and MCP autonest_plate/autonest_job report them;
the API returns NestResponse.Unplaced, persisted from response schema 5.

Reading a nest used to fill the engine's static BestFitCache as a side
effect, which is the only reason OpenNest.IO referenced OpenNest.Engine.
Core now defines SavedPairSet/SavedPairResult and IBestFitStore; the
mapping to BestFitResult moved verbatim into Engine's BestFitCacheStore.
NestReader/NestWriter take the store as an optional BestFitStore property
and skip bestfits/ entries without one.
Every production reader and writer opts into BestFitCacheStore.Shared, so
behaviour is unchanged; the golden round-trip test still matches byte for
byte.

Repo-wide sweep with the pinned CSharpier 1.3.0 tool. Whitespace and
line-wrapping only; OpenNest.Engine.Tests (109) and OpenNest.IO.Tests
pass after reformat, full solution builds 0 errors.
Added .csharpierignore so csproj/config XML keeps its existing layout
(CSharpier's XML wrapping churns attributes with zero benefit).
Formatting is now enforceable: dotnet csharpier check . passes.
Task 6 of the whole-job engine API: adapt the public NestRequest/NestRunner/
NestResponse surface to delegate to the whole-job runner instead of a manual
quantity loop.
- NestRequest: optional explicit Plates stock list (null keeps the legacy
unlimited SheetSize fallback; empty list means no available stock),
optional per-part Id (derived as part-{index} when absent), and an explicit
PlacementStrategy that takes precedence over the legacy Strategy.
- NestRequestPlate: one physical-stock type (id, size, quantity, spacing,
quadrant).
- NestRunner: imports each DXF once, propagates priority/rotation constraints,
runs a single NestJobRunner solve, materializes ID/pose placements exactly
once, and reports aggregate utilization as total placed part area over total
physical sheet area.
- NestResponse: exposes status, stop reason, part fulfillment, stock usage,
and plate-to-stock mapping; .nestquote save/load gains a schema version and
reports completion as unknown for old archives lacking fulfillment metadata.
- Tests: extend the Api request/runner/persistence suites for legacy SheetSize,
explicit mixed finite stock, stock exhaustion, weighted utilization, old
archive loading, and new-archive round trips.
Verification: cross-compiles clean on net8.0-windows (Linux). The Api tests
require a Windows runner (net8.0-windows) and are NOT executed here; the
delegated engine logic is covered by the 70-test net8.0 Engine.Tests suite
(committed in Task 5). Windows runtime verification remains outstanding.
Consolidated two stateless classes into one unified API: Dxf.Import(),
Dxf.GetGeometry(), Dxf.ExportPlate(), Dxf.ExportProgram(). Export
state moved into a private ExportContext. Removed bool+out pattern
from GetGeometry in favor of returning empty list on failure.

Material and thickness are properties of the nest (all plates share the
same material/gauge), not individual plates. This moves them to the Nest
class, removes them from Plate and PlateSettings, and updates the UI so
EditNestInfoForm has a material field while EditPlateForm no longer shows
thickness. The nest file format gains top-level thickness/material fields
with backward-compatible reading from PlateDefaults for old files.

Etch marks for up bends are now real geometry entities on an ETCH layer
instead of being drawn dynamically. They flow through the full pipeline:
entities → FilterPanel layers → ConvertGeometry (tagged as Scribe) →
post-processor sequencing before cut geometry.
Also includes ShapeProfile normalization (CW perimeter, CCW cutouts)
applied consistently across all import paths, and inward offset support
for cutout shapes in overlap/offset polygon calculations.

- NestRunner now assigns Material to plates from request.Material
- NestResponse.LoadAsync uses descriptive exceptions instead of null-forgiving operators
- Fix pre-existing FillExtents.Fill signature mismatch (add bestFits parameter)

Stateless orchestrator that takes a NestRequest and returns a NestResponse.
Imports DXFs, builds NestItems, runs the engine in a multi-plate loop until
all parts are placed, computes timing, and returns utilization metrics.

Adds NestResponse type to OpenNest.Api with SaveAsync/LoadAsync for .nestquote format — a ZIP containing request.json, response.json (metrics), and an embedded nest.nest.
