## Build and Test
For local verification, use [scripts/verify.sh](scripts/README.md#build-and-test-verification)
by default. It builds first, lists the tests, and runs the same selection. It stops
on failure and rejects an empty test selection. Use a normal configured build;
local verification does not require coverage collection or a CI run.
AGENTS.md: # Phlex — Kilo Agent Instructions
## Build and Test
For MPD test-only runs, follow the same-shell project selection and test commands
in [scripts/README.md](scripts/README.md#build-and-test-verification). Test-only
runs do not establish that the build is current.

<location>https://github.com/toeverything/blocksuite/blob/main/docs/guide/selection.md</location>
<excerpt>citeturn0search0 [wordlim: 200] Crawled: last month; If you select the blocks via block level selection like this:
# Selection
Selection is a very common concept in structure editors. It's used for representing the current cursor position or the current selected blocks.
In BlockSuite, we use a data driven approach to represent the selection. It also follows the CRDT-native data flow, which means the selection state is always derived from serializable data.
## Selection Model
The selection model contains a list of atomic selections. Each selection represents a range of the content. For example, if you have a text block with the following content:
> Hello
>
> World
In the default `PageEditor`, it will be modeled as following block tree nodes:
`Root Block
Note Block
Paragraph Block 1
Paragraph Block 2
`
So if you select the text partially via mouse drag as following:
The selection model will be:
[
{
type: 'text',
group: 'note',
from: {
path: ['root_id', 'note_id', 'paragraph_1_id'],
index: 1,
length: 5,
},
to: {
path: ['root_id', 'note_id', 'paragraph_2_id'],
index: 0,
length: 4,
},
},
];
If you select the blocks via block level selection like this:
The selection model will be:
[
{
type: 'block',
group: 'note',
path: ['root_id', 'note_id', 'paragraph_1_id'],
},
{
type: 'block',
group: 'note',
path: ['root_id', 'note_id', 'paragraph_2_id'],
},
];
## Types and Groups
Selection model has two important properties: `type` and `group`.
The `type` of a selection means which kind of selection it is. And the `group` of a selection indicates the scope of selection.
Some types of selections can share the same group because they have the same scope. For example, the `text` selection and the `block` selection can share the `note` group because they are both in the `affine:note` block. And you may also have a `cell` and `row` selection in a `table` block, and they can share the `table` group.
## Update Selection State
You can get the selection manager from `std.selection` or `host.selection`. With the selection manager, you can read the selection model from `value`. And you can also write the selection model by `set` and `update`:
const { selection } = host.std;
const current = selection.value;
const next = transformSelection(current);
selection.set(next);
// This can also be written as:
selection.update(current => transformSelection(current));
The `set` method will override all current selections.
You can also create a new selection by using `selection.create` method:
const blockSelection = selection.create('block', { path: [0, 1, 2] });
If you want to pick some selections by `type` from the current selection model, you can reuse the `pick` and `find` methods to help:
const textSelection: Selection = selection.pick('text');
const blockSelections: Selection[] = selection.find('block');
You can also clear all the selections by calling `clear`. If you just want to clear a certain type of selections, you can pass the type as the first argument of `clear` method:
// clear all selections
selection.clear();
// clear text selection
selection.clear('text');
And we also provide a `setGroup` method to override the selections in a specific group. Of course, we also provide a `getGroup` method.
const noteSelections = selection.getGroup('note');
const nextNoteSelections = yourLogic(noteSelections);
selection.setGroup('note', nextNoteSelections);

<excerpt>citeturn0search1 [wordlim: 200] Crawled: 3 days ago; The editor's state always holds at least one selection range.
# Example: Selection
The editor's state always holds at least one selection range. When multiple selections are enabled, it may have several.
Ranges consist of an anchor (the side that doesn't move when you shift-select) and a head (the moving side). When those are the same, it is a cursor selection, otherwise it is a range.
When there are multiple selection ranges, one of them will be considered the main range (this is also the one that the native selection will reflect). If you have an editor state, you can find the main selection range with `state.selection.main`. It is a `SelectionRange` object with `anchor` and `head` properties (and also `from`/`to` if you're interested in the minimum or maximum side) holding document positions.
Like any editor state change, moving the selection is done by dispatching a transaction. For example, this moves the cursor to the start of the document:
view.dispatch({selection: {anchor: 0}})
The `selection` property on a transaction spec takes either a shorthand `{anchor: number, head?: number}` object, or a full `EditorSelection` instance.

<excerpt>citeturn0search2 [wordlim: 200] Published: 1.1 years ago; Crawled: 3 months ago; •After setting up the Spack environment, an MPD project is selected for development by ... These improvements were largely achieved by avoiding the use of environmental variables
To determine which dependencies are required for the developed packages, the project
must be refreshed (see Figure 4), which usually takes a few minutes. The refresh stage
performs multiple steps:
•The recipes of the developed packages are used to create an anonymous development en-
vironment of those packages’ dependencies.
•A list of uninstalled dependencies required to proceed with development is printed to the
terminal. The developer then has the option to directly install the packages.
•Artifacts are generated to create one CMake project that includes the developed packages.
The refresh step must be invoked only when another repository is cloned for development or
whenever there are changes to a recipe of one of the developed packages.
Once the refresh step is complete, the developed packages may be built (see Figure 5).
The spack mpd build step automatically activates the anonymous development environ-
ment that was created as part of the refresh step. With the activated environment, the CMake
configuration step is then invoked, followed by the build command, which uses either GNU
Make or Ninja (depending on the MPD project configuration) [13,14]. Note that MPD uses
CMake directly and not Spack to build the developed packages.
After a successful build, any CMake-based unit tests [15] can be executed by invoking

Run MPD tests inside the project environment.
In --project mode, spack mpd build activates the project environment only for that command. The later direct ctest commands run outside it. Tests that require Spack-provided runtime dependencies can fail after a successful build. Use spack mpd test for both CTest operations in the MPD branch, or activate the project environment around them.

@marcpaterno Reviewed commit 32c986e. I found no new issues in the changes.
- Both MPD test operations now use
spack mpd test --. This addresses the project-environment concern. - Both operations retain the same test filter. Test execution retains verbose output, parallel execution, failure output, and empty-selection rejection.
- Standalone mode remains unchanged.
- The updated regression checks both MPD command invocations. Existing failure-path tests cover discovery, selection, build, listing, and execution failures.
git diff --check HEAD^ HEADpassed.
This was a static review. I did not run repository code. Please rerun the verifier regressions and one real MPD verification to confirm runtime behavior.
I will leave thread closure to a human, as required by AGENTS.md.

Summary
PR 1 of the five-PR concept-registry stack, based on
main. Isolate localverification and contributor/agent guidance before the framework changes.
scripts/verify.shwith MPD and standalone modes, optional test-name regex,and verbose output. With no regex, run the full configured suite.
invalid arguments, and empty selections.
document that a test-only rerun does not establish build freshness.
No framework runtime, GitHub Actions workflow, hook-version, or coverage
configuration change is included.
Evidence
against the initial replay: 2 failed, 16 passed.
After: Adding tool-default parallelism made all 18 verifier regressions pass,
including real CMake/CTest integrations; post-formatting reruns also passed.
scripts:unit: 451 pytest cases passed, zero skipped.A shell-only verifier change triggers the scripts-test hook.
Local macOS/AppleClang evidence, not CI approval. The two concept/registry tests
are introduced in PR 3; their absence here is intentional. Unavailable or disabled
optional configurations are not claimed as validated.
Merge Danger
Door: Two-way
Revertable without changing public framework APIs or persisted data. Later stack
validation uses this helper, so reverting it requires a replacement procedure.
Blast Radius: Tooling
Parallel builds/tests may increase resource use. Shell-only changes now run
script tests, and empty test selections fail instead of appearing successful.
