-- **Serialization boundary**: It must be persisted, sent over the wire, or written to config. The source type is unsuitable (unexported fields, function pointers, cycles).
-- **Invariant enforcement**: The constructor or methods enforce constraints that raw data does not carry (e.g., non-empty, validated format, bounded range).
-- **Multiple distinct consumers**: Three or more call sites use the type in meaningfully different ways. The type is the shared vocabulary between them.
-- **Dependency firewall**: The type lives in a lightweight package so that consumers avoid importing a heavy dependency.

+## How to approach a feature
+
+Building a feature is not one task, it is a sequence of concerns that build on each other. Work through them in this order:
+
+1. **Domain design (types).** Define the types that represent your domain. What are the entities, what are their relationships, what are the constraints? This is where you decide your data model. Get this right first because everything else depends on it. See [Packages](packages.md) and [Abstractions](abstractions.md).
+
+2. **Structure (services / modules / handlers).** Place your code in the right layer given the current infrastructure. If the current structure does not work for your feature, that is the time to open a discussion and write a technical document, not to silently reshape things in the same PR. See [Handler](handler.md) and [Provider](provider.md).
+
+3. **HTTP endpoints (paths, status codes, errors).** Pay close attention to detail here. Paths, methods, request/response shapes, status codes, error codes. These are the contract with consumers and are expensive to change after release. See [Endpoint](endpoint.md) and [Handler](handler.md).
+
+4. **Database constraints (org_id, foreign keys, migrations).** Ensure org scoping, schema consistency, and migration correctness. See [SQL](sql.md).
+
+5. **Business logic (module layer).** With the types, structure, endpoints, and storage in place, the focus narrows to the actual logic. This is where review should concentrate on correctness, edge cases, and error handling.
+
+This ordering also gives you a natural way to split PRs. Each layer affects a different area and requires a different lens for review. A PR that mixes refactoring with new feature logic is hard to review and risky to ship. Separate them.
+
+For large refactors or features that touch multiple subsystems, write a short technical document outlining the design and get relevant stakeholders aligned before starting implementation. This saves significant back-and-forth during review.

+# Testing
+
+This document provides rules for writing tests that catch real bugs and do not become a maintenance burden. It covers both how to write good tests and how to recognize bad ones.
+
+## Why we write tests
+
+Tests exist to give confidence that the system behaves correctly. A good test suite lets you change code and know immediately (or in a reasonable time) whether you broke something. A bad test suite lets you change code (and then spend hours figuring out whether the failures are real) and still lets the bugs slip in.
+
+Every test should be written to answer one question: **if this test fails, does that mean a user-visible behavior is broken?** If the answer is no, reconsider whether the test should exist.
+
+Not all tests are equal. Different scopes serve different purposes, and the balance matters.
+
+- **Unit tests**: Fast, focused, test a single function or type in isolation. These form the foundation. They should run in milliseconds, have no I/O, and be fully deterministic.
+- **Integration tests**: Verify that components work together against real dependencies (ClickHouse, PostgreSQL, etc.). Slower, but catch problems that unit tests cannot: real query behavior, configuration issues, serialization mismatches.
+- **End-to-end tests**: Validate full system behavior from the outside. Expensive to write and maintain, but necessary for critical user flows.
+
+When a test can be written at a smaller scope, prefer the smaller scope. But do not force a unit test where an integration test is the natural fit.
+
+## What to test
+
+### Test behaviors, not implementations
+
+A test should verify what the code does, not how it does it (unless the goal of the test is specifically how something happen). If you can refactor the internals of a function e.g, change a query, rename a variable, restructure the logic and no user-visible behavior changes, no test should break.
+
+```go
+// Good: tests the behavior "given this input, expect this output."
+func TestDiscountApplied(t *testing.T) {
+    order := NewOrder(item("widget", 100))
+    order.ApplyDiscount(10)
+    assert.Equal(t, 90, order.Total())
+}
+
+// Bad: tests the implementation "did it call the right internal method?"
+func TestDiscountApplied(t *testing.T) {
+    mockPricer := new(MockPricer)
+    mockPricer.On("CalculateDiscount", 100, 10).Return(90)
+    order := NewOrder(item("widget", 100), WithPricer(mockPricer))
+    order.ApplyDiscount(10)
+    mockPricer.AssertCalled(t, "CalculateDiscount", 100, 10)
+}
+```
+
+The first test survives a refactoring of how discounts are calculated. The second test breaks the moment you rename the method, change its signature, or inline the logic.
+
+**The refactoring test**: before committing a test, ask if someone refactors the internals tomorrow without changing any behavior, will this test break? If yes, consider updating the test.
+
+### Output format as behavior
+
+Some functions exist specifically to produce a formatted output: a query builder generates SQL, a serializer generates JSON, a code generator produces source code. In these cases, the output string *is* the behavior and asserting on it is valid and necessary. The function's contract is the exact output it produces.
+
+This is different from testing a function that *uses* a query internally. If a function's job is to fetch data from a database, the query it sends is an implementation detail and the returned data is the behavior. If its job is to *build* a query for someone else to execute, the query string is the behavior.
+
+The distinction: **is the formatted output the function's product, or the function's mechanism?** Test the product, not the mechanism.
+
+### Test at the public API boundary
+
+Write tests against the exported functions and methods that consumers actually call. Do not test unexported helpers directly. If an unexported function has complex logic worth testing, that is a signal it should be extracted into its own package with its own public API.
+
+### Test edge cases and error paths
+
+The most valuable tests cover the cases that are easy to get wrong:
+
+- Empty inputs, nil inputs, zero values.
+- Boundary conditions (off-by-one, first element, last element).
+- Error conditions (what happens when the dependency fails?).
+- Concurrent access, if the code is designed for it.
+
+A test for the happy path of a trivial function adds little value. A test for the error path of a complex function prevents real bugs.
+
+### The Beyonce Rule
+
+"If you liked it, then you should have put a test on it." Any behavior you want to preserve such as correctness, performance characteristics, security constraints, error handling should be covered by a test. If it breaks and there is no test, that is not a regression; it is an untested assumption.
+
+## How to write a test
+
+### Structure: arrange, act, assert
+
+Every test should have three clearly separated sections:
+
+```go
+func TestTransferInsufficientFunds(t *testing.T) {
+    // Arrange: set up the preconditions.
+    from := NewAccount(50)
+    to := NewAccount(0)
+
+    // Act: perform the operation being tested.
+    err := Transfer(from, to, 100)
+
+    // Assert: verify the outcome.
+    require.Error(t, err)
+    assert.Equal(t, 50, from.Balance())
+    assert.Equal(t, 0, to.Balance())
+}
+```
+
+Do not interleave setup and assertions. Do not put assertions in helper functions that also perform setup. Keep the three sections visually distinct.
+
+### One behavior per test
+
+Each test function should verify one behavior. If a test name needs "and" in it, split it into two tests.
+
+```go
+// Good: one behavior per test.
+func TestParseValidInput(t *testing.T) { ... }
+func TestParseEmptyInput(t *testing.T) { ... }
+func TestParseMalformedInput(t *testing.T) { ... }
+
+// Bad: multiple behaviors in one test.
+func TestParse(t *testing.T) {
+    // test valid input
+    // test empty input
+    // test malformed input
+}
+```
+
+Table-driven tests are fine when the behavior is the same and only the inputs/outputs vary.
+
+### Name tests after behaviors
+
+Test names should describe the scenario and the expected outcome, not the function being tested.
+
+```go
+// Good: describes the behavior.
+func TestWithdrawal_InsufficientFunds_ReturnsError(t *testing.T)
+func TestWithdrawal_ZeroBalance_ReturnsError(t *testing.T)
+
+// Bad: describes the function.
+func TestWithdraw(t *testing.T)
+func TestWithdrawError(t *testing.T)
+```
+
+### Eliminate logic in tests
+
+Tests should be straight-line code. No `if`, no `for`, no `switch`. If you feel the need to add control flow to a test, either split it into multiple tests or restructure the test data.
+
+A test with logic in it needs its own tests. That is a sign something has gone wrong.
+
+### Write clear failure messages
+
+When a test fails, the failure message should tell you what went wrong without reading the test source.
+
+```go
+// Good: failure message explains the context.
+assert.Equal(t, expected, actual, "discount should be applied to order total")
+
+// Bad: failure message is just the default.
+assert.Equal(t, expected, actual)
+```
+
+Use `require` for preconditions that must hold for the rest of the test to make sense. Use `assert` for the actual verifications. This avoids cascading failures from a single root cause.
+
+## How to recognize a bad test
+
+A bad test costs more to maintain than the bugs it prevents. Learning to identify bad tests is as important as learning to write good ones. Always evaluate a test critically before commiting it.
+
+### Tests that duplicate the implementation
+
+If a test contains the same logic as the code it tests, it verifies nothing. It will pass when the code is wrong in the same way the test is wrong, and it will break whenever the code changes even if the change is correct.
+
+A common form: mocking a database, setting up canned rows, calling a function that queries and scans those rows, then asserting that the function returned exactly those rows. The test encodes the query, the row structure, and the scan logic. The same things the production code does. If the function has no branching logic beyond "query and scan," this test is a mirror of the implementation, not a check on it. An integration test against a real database verifies the actual behavior; the mock-based test verifies that the code matches the test author's expectations of the code.
+
+### Tests for functions with no interesting logic
+
+Not every function needs a test. A function that prepares a query, sends it, and scans the result has no branching, no edge cases, and no logic that could be wrong independently of the query being correct. Unit-testing it means mocking the database, which means the test does not verify the query works. It only verifies the function calls the mock in the expected way.
+
+Ask: **what bug would this test catch that would not be caught by the integration test or by the tests of the calling code?** If the answer is nothing, skip the unit test. A missing test is better than a test that provides false confidence.
+
+### Tests that rebuild the dependency boundary
+
+When a test creates an in-package mock of an external interface (database driver, HTTP client, file system) and that mock contains non-trivial logic (reflection-based scanning, response simulation, state machines), the test is now testing its own mock as much as the production code. Bugs in the mock produce false passes or false failures, and the mock must be maintained alongside the real dependency.
+
+If the mock is complex enough to have its own bugs, you have rebuilt the dependency boundary rather than testing against it. Use the real dependency (via integration test) or use a well-maintained fake provided by the dependency's authors.
+
+### Tests that exist for coverage
+
+A test that exercises a function without meaningfully verifying its output adds coverage without adding confidence. Calling a type-conversion function with every numeric type and asserting it does not panic covers lines but does not catch regressions. The function would need to be rewritten to fail, and any such rewrite would be caught by the callers' tests.
+
+Before writing a test, identify the specific failure mode it guards against. If you cannot name one, the test is not worth writing.
+
+### Tests that test the language
+
+Do not test that language type system, standard library, or well-known third-party libraries work correctly. Testing that `reflect.Kind` returns the right value for each type, that pointer dereferencing works, or that a type switch dispatches correctly adds maintenance burden without catching any plausible bug in your code.
+
+## Brittle tests
+
+A brittle test is one that fails when production code changes without an actual bug being introduced. Brittle tests are expensive: they slow down development, train people to ignore failures, and provide no real safety net. Common sources of brittleness:
+
+- **Asserting on implementation details**: Verifying which internal methods were called, in what order, or with what intermediate values. If the method is renamed or the order changes but the output is the same, the test breaks for no reason.
+- **Asserting on serialized representations when the format is not the contract**: Matching exact SQL strings, JSON output, or log messages produced by a function whose job is not to produce that format.
+- **Over-constrained mocks**: Setting up a mock that expects specific arguments in a specific sequence. Any refactoring of the call pattern breaks the mock setup even if behavior is preserved.
+- **Shared mutable state**: Tests that depend on data left behind by other tests. A change in execution order or a new test case causes unrelated failures.
+- **Time-dependence**: Tests that use `time.Now()`, `time.Sleep()`, or real timers. These produce flaky results and break under load.
+
+When you encounter a brittle test, fix or delete it. Do not work around it.
+
+## DAMP
+
+Test code should prioritize clarity (DAMP: Descriptive And Meaningful Phrases).
+
+```go
+// DAMP: each test is self-contained and readable.
+func TestCreateUser(t *testing.T) {
+    user := User{Name: "Alice", Email: "alice@example.com"}
+    err := store.Create(ctx, user)
+    require.NoError(t, err)
+}
+
+func TestCreateDuplicateUser(t *testing.T) {
+    user := User{Name: "Alice", Email: "alice@example.com"}
+    _ = store.Create(ctx, user)
+    err := store.Create(ctx, user)
+    assert.ErrorIs(t, err, ErrAlreadyExists)
+}
+```
+
+Shared setup helpers are fine for constructing objects with sensible defaults. But each test should explicitly set the values it depends on rather than relying on hidden defaults in a shared fixture.
+
+## Flaky tests
+
+A flaky test is one that sometimes passes and sometimes fails without any code change. Flaky tests erode trust in the entire suite. Once people learn to re-run and ignore failures, real bugs slip through.
+
+Common causes and fixes:
+
+- **Timing and sleeps**: Replace `time.Sleep` with channels, condition variables, or polling with a timeout.
+- **Uncontrolled concurrency**: Use deterministic synchronization rather than relying on goroutine scheduling.
+- **Shared state between tests**: Each test should set up and tear down its own state.
+
+If a test is flaky and you cannot fix the root cause quickly, skip or delete it. A skipped test with an explanation is better than a flaky test that trains everyone to ignore red builds.
+
+## Code coverage
+
+Code coverage measures which lines were executed, not whether the code is correct. A function that is called but whose output is never checked has 100% coverage and 0% verification.
+
+Do not use coverage as a target to hit. Use it as a tool to find gaps such as untested error paths, unreachable branches, dead code. A codebase with 60% meaningful coverage is better than one with 95% coverage achieved by testing trivial getters.
+
+## Tests are code
+
+Tests must be maintained and they are not second-class citizen. You should apply the same standards for readability, naming, and structure that you apply to production code. We do not tolerate complexity in tests just because they are tests.
+
+However, tests should be simpler than production code. If a test requires its own helper library, complex setup, or nested control flow, step back and ask whether you are testing the right thing at the right level. This is not a blanket rule but a prompt to pause, assess the situation, and check whether the complexity is justified.
+
+## What should I remember?
+
+- If refactoring internals breaks your test but no behavior changed, the test is likely bad. Delete it or consider updating it.
+- Test what the code does, not how it does it. Verify outputs and state, not method calls.
+- Output format is behavior when the function's job is to produce that format. It is not behavior when the function uses it internally.
+- Ask what specific bug this test catches. If you cannot name one, do not write it.
+- Always evaluate whether the test adds confidence, not just lines.
+- One behavior per test. Name it after the scenario, not the function.
+- No logic in tests. Straight-line code only.
+- Flaky tests are not acceptable. Fix the root cause or nuke the test code.
+- Coverage measures execution, not correctness.

+# Types
+
+This guide covers how types are organised, named, constructed, and composed so you can add new ones consistently.
+
+## Where do types live?
+
+Types live in `pkg/types/` and its sub-packages:
+
+```
+pkg/types/
+├── auditable.go          # TimeAuditable, UserAuditable
+├── identity.go           # Identifiable (UUID primary key)
+├── user.go               # User, PostableRegisterOrgAndAdmin, UserStore
+├── alertmanagertypes/    # Alert manager domain types
+│   ├── channel.go
+│   ├── receiver.go
+│   └── config.go
+├── authtypes/            # Auth domain types
+└── ruletypes/            # Rule domain types
+    └── maintenance.go
+```
+
+Follow these rules:
+
+1. **Embeddable building blocks** go in `pkg/types/` directly `Identifiable`, `TimeAuditable`, `UserAuditable`.
+2. **Domain-specific types** go in a sub-package named `pkg/types/<domain>types/` (e.g., `alertmanagertypes`, `ruletypes`, `authtypes`).
+3. **No domain logic** in type packages. Only data structures, constants, and simple methods. Domain services import from type packages, not the other way around.
+4. **Domain services import types, not vice versa.** If a type needs a service, the design is likely wrong and you should restructure so the service operates on the type.
+
+## Type variants
+
+A domain entity often has multiple representations depending on where it appears in the system. We use naming prefixes to distinguish them:
+
+| Prefix | Purpose | Example |
+|---|---|---|
+| `Postable<Type>` | API request input | `PostableRegisterOrgAndAdmin` |
+| `Gettable<Type>` | API response output | `GettablePlannedMaintenance` |
+| `Storable<Type>` | Database model (embeds `bun.BaseModel`) | `StorablePlannedMaintenance` |
+| Plain `<Type>` | Domain logic type | `User` |
+
+Not every entity needs all four variants. Start with the plain type and add variants only when the API or database representation genuinely differs.
+
+Here is a concrete example from `pkg/types/ruletypes/maintenance.go`:
+
+```go
+// Database model embeds bun.BaseModel and composition types
+type StorablePlannedMaintenance struct {
+    bun.BaseModel `bun:"table:planned_maintenance"`
+    types.Identifiable
+    types.TimeAuditable
+    types.UserAuditable
+    Name        string    `bun:"name,type:text,notnull"`
+    Description string    `bun:"description,type:text"`
+    Schedule    *Schedule `bun:"schedule,type:text,notnull"`
+    OrgID       string    `bun:"org_id,type:text"`
+}
+
+// API response: flat struct with JSON tags, computed fields like Status
+type GettablePlannedMaintenance struct {
+    Id          string    `json:"id"`
+    Name        string    `json:"name"`
+    Description string    `json:"description"`
+    Schedule    *Schedule `json:"schedule"`
+    RuleIDs     []string  `json:"alertIds"`
+    CreatedAt   time.Time `json:"createdAt"`
+    CreatedBy   string    `json:"createdBy"`
+    UpdatedAt   time.Time `json:"updatedAt"`
+    UpdatedBy   string    `json:"updatedBy"`
+    Status      string    `json:"status"`
+    Kind        string    `json:"kind"`
+}
+```
+
+When the API shape exactly matches the domain type, use a type alias instead of duplicating fields:
+
+```go
+// From pkg/types/user.go
+type GettableUser = User
+```
+
+## Composition via embedding
+
+`pkg/types/` provides small, reusable structs that you embed into your domain types:
+
+```go
+// pkg/types/identity.go
+type Identifiable struct {
+    ID valuer.UUID `json:"id" bun:"id,pk,type:text"`
+}
+
+// pkg/types/auditable.go
+type TimeAuditable struct {
+    CreatedAt time.Time `bun:"created_at" json:"createdAt"`
+    UpdatedAt time.Time `bun:"updated_at" json:"updatedAt"`
+}
+
+type UserAuditable struct {
+    CreatedBy string `bun:"created_by,type:text" json:"createdBy"`
+    UpdatedBy string `bun:"updated_by,type:text" json:"updatedBy"`
+}
+```
+
+Compose them in a database model:
+
+```go
+type StorablePlannedMaintenance struct {
+    bun.BaseModel `bun:"table:planned_maintenance"`
+    types.Identifiable    // adds ID (UUID primary key)
+    types.TimeAuditable   // adds CreatedAt, UpdatedAt
+    types.UserAuditable   // adds CreatedBy, UpdatedBy
+    Name        string    `bun:"name,type:text,notnull"`
+    Description string    `bun:"description,type:text"`
+}
+```
+
+See [SQL](sql.md) for full database patterns including migrations and queries.
+
+## Constructors
+
+Constructors validate inputs and return a ready-to-use value:
+
+```go
+// New<Type> validates and returns a pointer + error
+func NewUser(displayName string, email valuer.Email, role Role, orgID valuer.UUID) (*User, error) {
+    if email.IsZero() {
+        return nil, errors.New(errors.TypeInvalidInput, errors.CodeInvalidInput, "email is required")
+    }
+    if role == "" {
+        return nil, errors.New(errors.TypeInvalidInput, errors.CodeInvalidInput, "role is required")
+    }
+    if orgID.IsZero() {
+        return nil, errors.New(errors.TypeInvalidInput, errors.CodeInvalidInput, "orgID is required")
+    }
+
+    return &User{
+        Identifiable:  Identifiable{ID: valuer.GenerateUUID()},
+        DisplayName:   displayName,
+        Email:         email,
+        Role:          role,
+        OrgID:         orgID,
+        TimeAuditable: TimeAuditable{CreatedAt: time.Now(), UpdatedAt: time.Now()},
+    }, nil
+}
+```
+
+Follow these conventions:
+
+- **`New<Type>(args) (*Type, error)`**: validates inputs, returns an error on failure. Use this in production code.
+- **Validation at construction**: check required fields, format constraints, and invariants in the constructor. Callers should not need to validate after construction.
+- **Generate IDs internally**: constructors call `valuer.GenerateUUID()` callers do not pass IDs in.
+- **Set timestamps internally**: constructors set `CreatedAt` and `UpdatedAt` to `time.Now()`.
+
+## Typed domain values (`pkg/valuer/`)
+
+The `pkg/valuer` package provides typed wrappers for common domain values. These types carry validation, normalization, and consistent serialization (JSON, SQL, text) that raw Go primitives do not.
+
+| Type | Wraps | Invariant |
+|---|---|---|
+| `valuer.UUID` | `google/uuid.UUID` | Valid UUIDv7, generated via `GenerateUUID()` |
+| `valuer.Email` | `string` | Valid email format, lowercased and trimmed |
+| `valuer.String` | `string` | Lowercased and trimmed |
+| `valuer.TextDuration` | `time.Duration` | Valid duration, text-serializable |
+
+### When to use a valuer type
+
+Use a valuer type instead of a raw primitive when the value represents a domain concept with any of:
+
+- **Enums**: All enums in the codebase must be backed by `valuer.String`. Do not use raw `string` constants or `iota`-based `int` enums. A struct embedding `valuer.String` with predefined variables gives you normalization, serialization, and an `Enum()` method for OpenAPI schema generation in one place.
+- **Validation**: emails must match a format, UUIDs must be parseable, durations must be valid.
+- **Normalization**: `valuer.String` lowercases and trims input, so comparisons are consistent throughout the system.
+- **Serialization boundary**: the value is stored in a database, sent over the wire, or bound from an HTTP parameter. Valuer types implement `Scan`, `Value`, `MarshalJSON`, `UnmarshalJSON`, and `UnmarshalParam` consistently.
+
+```go
+// Wrong: raw string constant with no validation or normalization.
+const SignalTraces = "traces"
+
+// Right: valuer-backed type that normalizes and serializes consistently.
+type Signal struct {
+    valuer.String
+}
+
+var SignalTraces = Signal{valuer.NewString("traces")}
+```
+
+Only primitive domain types that serve as shared infrastructure belong in `pkg/valuer`. If you need a new base type (like `Email` or `TextDuration`) that multiple packages will embed for validation and serialization, add it there. Domain-specific types that build on top of a valuer (like `Signal` embedding `valuer.String`) belong in their own domain package, not in `pkg/valuer`.
+
+### The `Valuer` interface
+
+Every valuer type implements the `Valuer` interface, which gives you serialization for free:
+
+```go
+type Valuer interface {
+    IsZero() bool                        // check for zero value
+    StringValue() string                 // raw string representation
+    fmt.Stringer                         // String() for printing
+    json.Marshaler / json.Unmarshaler    // JSON
+    sql.Scanner / driver.Valuer          // database
+    encoding.TextMarshaler / TextUnmarshaler  // text
+    ginbinding.BindUnmarshaler           // HTTP query/path params
+}
+```
+
+Use them in struct fields:
+
+```go
+type User struct {
+    Identifiable
+    Email valuer.Email `bun:"email" json:"email"`
+    OrgID valuer.UUID  `bun:"org_id" json:"orgId"`
+}
+```
+
+## Wrappers must add semantics, not just rename
+
+A wrapper type is justified when it adds meaning, validation, or invariants that the underlying type does not carry. It is not justified when it merely renames fields or reorganizes the same data into a different shape.
+
+```go
+// Justified: adds validation that the underlying string does not carry.
+type OrgID struct{ value string }
+func NewOrgID(s string) (OrgID, error) { /* validates format */ }
+
+// Not justified: renames fields with no new invariant or behavior.
+type UserInfo struct {
+    Name  string // same as source.Name
+    Email string // same as source.Email
+}
+```
+
+Ask: what does the wrapper guarantee that the underlying type does not? If the answer is nothing, use the underlying type directly.
+
+## When a new type IS warranted
+
+A new type earns its place when it meets **at least one** of these criteria:
+
+- **Serialization boundary**: It must be persisted, sent over the wire, or written to config. The source type is unsuitable (unexported fields, function pointers, cycles).
+- **Invariant enforcement**: The constructor or methods enforce constraints that raw data does not carry (e.g., non-empty, validated format, bounded range).
+- **Multiple distinct consumers**: Three or more call sites use the type in meaningfully different ways. The type is the shared vocabulary between them.
+- **Dependency firewall**: The type lives in a lightweight package so that consumers avoid importing a heavy dependency.
+
+See [Abstractions](abstractions.md) for the full set of rules on when abstractions are and aren't justified.
+
+## Store interfaces
+
+Each domain type package defines a store interface for persistence. The store interface lives alongside the types it operates on:
+
+```go
+// From pkg/types/ruletypes/maintenance.go
+type MaintenanceStore interface {
+    CreatePlannedMaintenance(context.Context, GettablePlannedMaintenance) (valuer.UUID, error)
+    DeletePlannedMaintenance(context.Context, valuer.UUID) error
+    GetPlannedMaintenanceByID(context.Context, valuer.UUID) (*GettablePlannedMaintenance, error)
+    EditPlannedMaintenance(context.Context, GettablePlannedMaintenance, valuer.UUID) error
+    GetAllPlannedMaintenance(context.Context, string) ([]*GettablePlannedMaintenance, error)
+}
+```
+
+Conventions:
+
+- Name the interface `<Domain>Store` (e.g., `UserStore`, `MaintenanceStore`).
+- Accept `context.Context` as the first parameter.
+- Use typed values (`valuer.UUID`, `valuer.Email`) instead of raw strings for identifiers.
+- Implementations go in separate packages (e.g., `sqlstore/`), see [SQL](sql.md) for details.
+
+## What should I remember?
+
+- Shared types live in `pkg/types/`, domain types in `pkg/types/<domain>types/`.
+- No domain logic in type packages only data structures, constants, and simple methods.
+- Use `Storable`, `Gettable`, `Postable` prefixes when API or database representation differs from the domain type.
+- Embed `Identifiable`, `TimeAuditable`, and `UserAuditable` for standard fields instead of repeating them.
+- Constructors (`New<Type>`) validate, generate IDs, and set timestamps.
+- Use `pkg/valuer/` types instead of raw strings for domain identifiers like UUIDs and emails.
+- Store interfaces live alongside the types they persist and use `context.Context` as the first parameter.

+// Metric aggregation options resolution:
+//   The component maintains a ref (metricsRef) of the latest API results.
+//   When the user commits a metric name (via dropdown select, blur, or Cmd+Enter),
+//   resolveMetricFromText looks up the metric in metricsRef to determine its type
+//   (Sum, Gauge, Histogram, etc.). If the metric isn't found (e.g. the user typed
+//   a name before the debounced search returned), the type is empty and downstream
+//   treats it as unknown.
+//
+// Selection handling:
+//   - Dropdown select: user picks from the dropdown; type is always resolved
+//      since the option came from the current API results.
+//   - Blur: user typed a name and tabbed/clicked away without selecting from
+//      the dropdown. If the name differs from the current metric, it's resolved
+//      and committed. If the input is empty, it resets to the current metric name.
+//   - Cmd/Ctrl+Enter: resolves the typed name and commits it using flushSync
+//      so the state update is processed synchronously before QueryBuilderV2's
+//      onKeyDownCapture fires handleRunQuery. Uses document-level capture phase

+//      need to be handled here. TODO(srikanthccv): enter before n/w req completion
