+macOS iMessage SQLite chat.db watcher and `MessageSourceAdapter`
+implementation. Polls Apple's `~/Library/Messages/chat.db`, decodes
+Apple-epoch / nanosecond timestamps, resolves handle + chat +
+attachment joins, and emits `ParsedIMessage` and `InboundMessage`
+envelopes. Server-tier (Bun); the `bun:sqlite` driver is loaded
+lazily inside the production reader so the package type-checks +
+lints on every host.

+## Highlights
+
+- **`IMessageWatcher`** — Zod-validated config boundary, AbortSignal
+  propagation, injectable `SqliteReader`, typed `EventBus` surface
+  alongside the upstream `on/off` listener API, monotonic
+  `lastRowId` cursor (settable + readable for resume), filters for
+  `includeFromMe` and `chatFilter`.
+- **`IMessageAdapter`** — wraps the watcher and projects each
+  `ParsedIMessage` into a channel-agnostic `InboundMessage` with
+  normalised phone numbers and chat metadata.
+- **`IMessageParser`** — pure-function parser for chat.db row shapes;
+  Apple-epoch decoding, attachment fallbacks, phone normalisation.
+- **`createChatDbFixture`** — real chat.db-shaped SQLite database
+  builder used by tests so every test path runs against the same SQL
+  the production watcher executes — no mocks.
+- **`bunSqliteReader` / `createBunSqliteReader`** — production
+  `SqliteReader` backed by Bun's `bun:sqlite`. Errors are wrapped in
+  `IMessageDbOpenFailedError`.
+
+## Install
+
+```bash
+bun add @suaveplan/imessage-adapter
+```
+
+## Usage
+
+```ts
+import { IMessageAdapter } from "@suaveplan/imessage-adapter";
+
+const adapter = new IMessageAdapter();
+await adapter.initialize({
+    dbPath: "~/Library/Messages/chat.db",
+    pollIntervalMs: 5000,
+    includeFromMe: false,
+});
+
+for (const inbound of await adapter.poll()) {
+    console.log(inbound.sourceAddress, inbound.content);
+    adapter.markProcessed(inbound.id);
+}
+
+await adapter.close();
+```
+

+# `IMessageAdapter`
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+
+## Purpose
+
+`MessageSourceAdapter`-shaped wrapper around `IMessageWatcher` that
+projects each `ParsedIMessage` into the channel-agnostic
+`InboundMessage` envelope consumed by downstream inbound-message
+routers (e.g. a future `@suaveplan/api-plugin-messaging`). The
+adapter is the polymorphic surface — callers depend on
+`MessageSourceAdapter`, swap in iMessage / SMS / Slack adapters
+without coupling to chat.db schema details.
+
+## Features
+
+- `type === "imessage"` constant so multi-adapter routers can fan
+  out by source.
+- `initialize(config)` Zod-validates the input via
+  `parseAdapterConfig` and constructs the underlying watcher with
+  the validated config (including any injected `sqliteReader`).
+- `poll()` calls the watcher's `poll()` and projects each parsed
+  message into an `InboundMessage`. Attachments populate the
+  `attachments` array; the `contentType` is `"attachment"` when
+  ≥1 attachment is present and `"text"` otherwise.
+- `sourceAddress` is the parser-normalised phone number (or the
+  unchanged email handle), so downstream consumers see a
+  canonicalised identity.
+- `metadata` block carries chat-level context (`chatIdentifier`,
+  `chatDisplayName`, `isGroupChat`, `senderService`, `isRead`) that
+  routers need for routing decisions.
+- `getLastProcessedId() / markProcessed(id)` expose the consumer-
+  side cursor; `close()` stops the running watcher and clears the
+  reference.
+- `poll()` called before `initialize()` throws
+  `IMessageAdapterNotInitializedError`
+  (`IMESSAGE.ADAPTER_NOT_INITIALIZED`).
+
+## Usage: Basic
+
+```ts
+import { IMessageAdapter } from "@suaveplan/imessage-adapter";
+
+const adapter = new IMessageAdapter();
+await adapter.initialize({ pollIntervalMs: 5000 });
+const inbound = await adapter.poll();
+await adapter.close();
+```
+
+## Usage: Advanced
+
+```ts
+import {
+    IMessageAdapter,
+    createBunSqliteReader,
+} from "@suaveplan/imessage-adapter";
+
+const adapter = new IMessageAdapter();
+await adapter.initialize({
+    dbPath: "/tmp/chat.db",
+    sqliteReader: createBunSqliteReader(),
+    includeFromMe: true,
+});
+
+for (const msg of await adapter.poll()) {
+    if (msg.metadata?.["isGroupChat"]) {
+        adapter.markProcessed(msg.id);
+    }
+}
+```
+
+## API Reference
+
+- `type: "imessage"` — read-only adapter discriminator.
+- `initialize(config: Record<string, unknown>): Promise<void>`.
+- `poll(): Promise<readonly InboundMessage[]>`.
+- `getLastProcessedId(): string | null`.
+- `markProcessed(id: string): void`.
+- `close(): Promise<void>` — idempotent.
+
+## Implementation Notes
+
+The adapter owns the watcher's lifecycle: `close()` stops the loop if
+`isRunning()`, then drops the reference. The projection is pure — no
+side effects, no extra DB calls — so projecting N messages costs O(N)
+and never re-opens the database. The `attachments` array is always
+present (possibly empty) so consumers can iterate without a
+null-check.

+# `IMESSAGE_*` error registry
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+
+## Purpose
+
+Defines the stable, fully-qualified error-code registry for
+`@suaveplan/imessage-adapter`. Every error class in this module
+inherits from `@suaveplan/error`'s `SuaveplanError` base and carries
+one of the ten `IMESSAGE.*` codes returned by `defineCodes("IMESSAGE",
+[...])`. Consumers downstream — loggers, problem+json renderers, retry
+wrappers, OTel attribute writers — map on the code, never on the
+message or class identity, so the codes are part of the public API.
+
+## Features
+
+- Ten production codes, each thrown from at least one real call site:
+  `DB_OPEN_FAILED`, `DB_QUERY_FAILED`, `WATCHER_NOT_RUNNING`,
+  `WATCHER_ALREADY_RUNNING`, `ADAPTER_NOT_INITIALIZED`,
+  `INVALID_CONFIG`, `POLL_ABORTED`, `POLL_FAILED`,
+  `ATTACHMENT_PARSE_FAILED`, `APPLE_DATE_PARSE_FAILED`.
+- One typed error class per code, all extending the abstract
+  `IMessageError` so consumers can pattern-match via `instanceof
+  IMessageError` for a single catch site.
+- `IMessageInvalidConfigError` accepts a `issues` payload that is
+  merged into `context` so callers can recover the Zod issue array
+  from problem+json bodies.
+- Frozen `IMESSAGE_CODES` record keeps the literal-typed union
+  reachable through the public surface.
+
+## Usage: Basic
+
+```ts
+import {
+    IMessageAdapterNotInitializedError,
+} from "@suaveplan/imessage-adapter";
+
+throw new IMessageAdapterNotInitializedError();
+```
+
+## Usage: Advanced
+
+```ts
+import {
+    IMessageError,
+    IMessageInvalidConfigError,
+    IMESSAGE_CODES,
+} from "@suaveplan/imessage-adapter";
+
+try {
+    parseWatcherConfig(input);
+} catch (err) {
+    if (err instanceof IMessageInvalidConfigError) {
+        console.error(err.code, err.context["issues"]);
+    } else if (err instanceof IMessageError) {
+        switch (err.code) {
+            case IMESSAGE_CODES.WATCHER_ALREADY_RUNNING:
+            case IMESSAGE_CODES.WATCHER_NOT_RUNNING:
+                // recoverable
+                break;
+            default:
+                throw err;
+        }
+    } else {
+        throw err;
+    }
+}
+```
+
+## API Reference
+
+- `const IMESSAGE_CODES`: frozen record `{ DB_OPEN_FAILED:
+  "IMESSAGE.DB_OPEN_FAILED", ... }`.
+- `type IMessageErrorCode`: union of every fully-qualified code.
+- `abstract class IMessageError extends SuaveplanError<IMessageErrorCode>`.
+- One concrete class per code, each accepting `{ cause?, context?,
+  traceId?, message? }`.
+
+## Implementation Notes
+
+The module side-effect-imports nothing; the registry is purely
+declarative. The package barrel (`src/index.ts`) side-effect-imports
+`./error-codes/index.js` so subpath consumers also observe the
+registration. Messages default to i18n keys (`imessage.errors.*`) so
+callers can supply their own resolver if they wish.

+# `createChatDbFixture`
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+
+## Purpose
+
+Builds a real `chat.db`-shaped SQLite database on a temp path using
+the structural `SqliteReader` seam. This is the foundation of the
+test strategy: every watcher / adapter test runs against a real
+`bun:sqlite` database whose schema mirrors Apple's Messages app,
+populated via the helpers returned by this factory. There are no
+mocks anywhere in the call chain — the SQL the watcher executes in
+production runs unchanged against the fixture.
+
+## Features
+
+- DDL covers the six tables the watcher reads:
+  `message`, `handle`, `chat`, `chat_message_join`, `attachment`,
+  `message_attachment_join` — with the exact column names + types
+  Apple's chat.db uses.
+- Helpers return the inserted ROWID via a `SELECT ROWID ORDER BY
+  ROWID DESC LIMIT 1` so tests can wire foreign-key joins
+  deterministically without depending on `last_insert_rowid()`
+  semantics across reader implementations.
+- `insertMessage(row, chatId)` writes both the message and its
+  `chat_message_join` row so the watcher's `JOIN cmj` query finds
+  the chat without extra wiring.
+- `insertAttachment(row, messageId)` writes both the attachment and
+  its `message_attachment_join` row.
+- `close()` closes the handle so the temp file can be deleted by the
+  caller's `afterEach`.
+
+## Usage: Basic
+
+```ts
+import { tmpdir } from "node:os";
+import { join } from "node:path";
+import {
+    createBunSqliteReader,
+    createChatDbFixture,
+} from "@suaveplan/imessage-adapter";
+
+const reader = createBunSqliteReader();
+const fixture = createChatDbFixture(reader, join(tmpdir(), "chat.db"));
+const chatId = fixture.insertChat({
+    guid: "iMessage;+;+15551234567",
+    chat_identifier: "+15551234567",
+    display_name: null,
+    group_id: null,
+    service_name: "iMessage",
+    is_archived: 0,
+});
+fixture.close();
+```
+
+## Usage: Advanced
+
+```ts
+const handleId = fixture.insertHandle({
+    id: "+15551234567",
+    country: "us",
+    service: "iMessage",
+    uncanonicalized_id: null,
+});
+const messageId = fixture.insertMessage({
+    guid: "m-1",
+    text: "Hello",
+    handle_id: handleId,
+    service: "iMessage",
+    date: 700_000_000,
+    date_read: 0,
+    date_delivered: 0,
+    is_from_me: 0,
+    is_read: 1,
+    is_delivered: 1,
+    is_sent: 0,
+    cache_has_attachments: 1,
+    associated_message_guid: null,
+    associated_message_type: 0,
+    balloon_bundle_id: null,
+    group_title: null,
+}, chatId);
+fixture.insertAttachment({
+    guid: "a-1",
+    filename: "/tmp/photo.jpg",
+    mime_type: "image/jpeg",
+    total_bytes: 1024,
+    transfer_name: "photo.jpg",
+}, messageId);
+```
+
+## API Reference
+
+- `createChatDbFixture(reader, path): ChatDbFixture` — DDLs the schema
+  and returns the helpers.
+- `ChatDbFixture.handle: SqliteHandle` — exposed for advanced custom
+  inserts.
+- `insertHandle(row): number` — returns the new ROWID.
+- `insertChat(row): number` — returns the new ROWID.
+- `insertMessage(row, chatId?): number` — wires the
+  `chat_message_join` row when `chatId` is supplied.
+- `insertAttachment(row, messageId): number` — wires the
+  `message_attachment_join` row.
+- `close(): void` — closes the handle.
+
+## Implementation Notes
+
+The factory is server-tier-only because it requires a real SQLite
+implementation, but it accepts any `SqliteReader` so a future
+in-process SQLite-WASM reader could also drive the fixture. The
+schema uses `AUTOINCREMENT` so insertion order maps to monotonically
+increasing ROWIDs, which the watcher's `ROWID > lastRowId` cursor
+relies on for incremental polling.

+# OpenTelemetry instrumentation
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+
+## Purpose
+
+Defines the four OpenTelemetry instruments emitted by
+`@suaveplan/imessage-adapter` and the helpers that record onto them.
+Instruments are resolved against the package-named `Meter`
+(`@suaveplan/imessage-adapter` / `0.1.0`) so consumers can filter to
+just this package in their dashboards. `refreshIMessageMeters()`
+re-binds every instrument against the current global `MeterProvider`,
+which tests use to redirect emissions to an in-memory exporter.
+
+## Features
+
+- Counter `imessage.messages_emitted_total` with `{chat_type,
+  from_me}` attributes — incremented once per parsed message yielded
+  by `IMessageWatcher.poll()`.
+- Counter `imessage.attachments_emitted_total` with `{mime_family}` —
+  incremented once per parsed attachment.
+- Counter `imessage.poll_errors_total` with `{code}` — incremented on
+  every poll-loop error, attributed by `IMESSAGE.*` code.
+- Histogram `imessage.poll_duration_ms` with `{outcome}` (`ok` /
+  `error` / `aborted`) — records the wall-clock duration of every
+  completed (or cancelled) poll tick in milliseconds.
+
+## Usage: Basic
+
+```ts
+import {
+    recordMessageEmitted,
+    recordPollDuration,
+} from "@suaveplan/imessage-adapter/otel";
+
+recordMessageEmitted("direct", false);
+recordPollDuration(42, "ok");
+```
+
+## Usage: Advanced
+
+```ts
+import { metrics } from "@opentelemetry/api";
+import { refreshIMessageMeters } from "@suaveplan/imessage-adapter";
+
+metrics.setGlobalMeterProvider(meterProvider);
+refreshIMessageMeters(); // re-resolve so subsequent records land on this provider
+```
+
+## API Reference
+
+- `recordMessageEmitted(chatType: "direct" | "group", fromMe: boolean): void`
+- `recordAttachmentEmitted(mimeFamily: string): void`
+- `recordPollError(code: string): void`
+- `recordPollDuration(durationMs: number, outcome: "ok" | "error" | "aborted"): void`
+- `refreshIMessageMeters(): void` — re-bind every instrument against the
+  current global `MeterProvider`.
+
+## Implementation Notes
+
+The instruments are stored in mutable module-level bindings so
+`refreshIMessageMeters()` can swap them in-place; this is the
+canonical pattern used by `slack-client` and the other
+messaging clients. The `mime_family` attribute is computed by the
+caller (typically the watcher) as the first segment of the MIME type
+so cardinality stays bounded.

+# `IMessageParser`
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+
+## Purpose
+
+Pure-function parser that turns Apple's chat.db row shapes into the
+`ParsedIMessage` projection consumed by every downstream surface in
+this package. The parser handles Apple's per-row timestamp mode
+(seconds vs nanoseconds since 2001-01-01), resolves nullable join
+rows, and normalises phone-number handles into the canonical
+`+E.164` form.
+
+## Features
+
+- `parseMessage(row, handle, chat, attachments)` — composes the row +
+  optional join rows into a `ParsedIMessage`. Null handles project
+  to `"unknown"`, null chat identifiers to `""`, and the group-chat
+  flag is set when the chat identifier starts with `"chat"`.
+- `parseAppleDate(n)` — auto-detects seconds vs nanoseconds against
+  the `10^9` threshold, applies the 2001-01-01 Apple epoch offset,
+  and throws `IMessageAppleDateParseError` on `NaN` / non-finite
+  input rather than silently returning a garbage `Date`.
+- `parseAttachment(row)` — picks `transfer_name` over `filename` over
+  `"unknown"` and defaults the MIME type to
+  `"application/octet-stream"` when chat.db omits it.
+- `isGroupChat(chatIdentifier)` — exposes the same chat-vs-handle
+  classifier used internally so consumers can reuse it for routing.
+- `normalizePhoneNumber(handle)` — strips non-digit characters and
+  prefixes 10-digit US numbers with `+1`, 11-digit US numbers with
+  `+`; email handles pass through unchanged.
+
+## Usage: Basic
+
+```ts
+import { IMessageParser } from "@suaveplan/imessage-adapter/parser";
+
+const parser = new IMessageParser();
+const sent = parser.parseAppleDate(700_000_000);
+```
+
+## Usage: Advanced
+
+```ts
+import { IMessageParser } from "@suaveplan/imessage-adapter";
+
+const parser = new IMessageParser();
+const parsed = parser.parseMessage(messageRow, handleRow, chatRow, attachments);
+if (parsed.isGroupChat) {
+    route(parsed, parser.normalizePhoneNumber(parsed.senderHandle));
+}
+```
+
+## API Reference
+
+- `parseMessage(row, handle, chat, attachments?): ParsedIMessage`
+- `parseAppleDate(n: number): Date` — throws
+  `IMessageAppleDateParseError` for `NaN` / non-finite.
+- `parseAttachment(row): ParsedAttachment`
+- `isGroupChat(chatIdentifier: string): boolean`
+- `normalizePhoneNumber(handle: string): string`
+
+## Implementation Notes
+
+The parser is intentionally side-effect-free and instance-based (no
+static methods) so consumers can subclass it to override individual
+steps — for example, to swap in a locale-aware phone normaliser. The
+Apple-epoch threshold detection runs per-row because Apple's schema
+shipped both forms historically; checking the magnitude is robust
+across the migration window. Errors are routed through the
+`IMESSAGE.*` registry so consumers can map by code.

+# Config schemas
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+
+## Purpose
+
+Provides Zod boundary schemas for `IMessageWatcherConfig` and
+`IMessageAdapterConfig`, plus the `parseWatcherConfig` /
+`parseAdapterConfig` helpers that callers use to validate untrusted
+input before constructing a watcher or adapter. Both schemas are
+strict — extra keys are rejected — so consumers cannot silently
+smuggle additional fields past the boundary.
+
+## Features
+
+- Strict object validation (`.strict()`) — unknown properties are
+  rejected at the boundary, preventing prototype-pollution-style
+  smuggling.
+- `pollIntervalMs` constrained to positive integers; `sinceDate`
+  required to be a `Date` instance (no millisecond-since-epoch
+  numbers); `chatFilter` constrained to string arrays.
+- Custom `SqliteReaderSchema` confirms the optional injected
+  `sqliteReader` exposes a callable `open()` member.
+- Failures throw `IMessageInvalidConfigError`
+  (`IMESSAGE.INVALID_CONFIG`) carrying a serialisable `issues` array
+  in `context` so problem+json responders can surface the Zod path +
+  reason without re-running the schema.
+
+## Usage: Basic
+
+```ts
+import { parseWatcherConfig } from "@suaveplan/imessage-adapter/schemas";
+
+const config = parseWatcherConfig({ pollIntervalMs: 5000 });
+```
+
+## Usage: Advanced
+
+```ts
+import {
+    parseWatcherConfig,
+    IMessageInvalidConfigError,
+} from "@suaveplan/imessage-adapter";
+
+try {
+    parseWatcherConfig({ pollIntervalMs: -1, oops: true });
+} catch (err) {
+    if (err instanceof IMessageInvalidConfigError) {
+        return Response.json(
+            { issues: err.context["issues"] },
+            { status: 400 },
+        );
+    }
+    throw err;
+}
+```
+
+## API Reference
+
+- `IMessageWatcherConfigSchema: z.ZodObject` — validates watcher config.
+- `IMessageAdapterConfigSchema` — alias for the watcher schema.
+- `SqliteReaderSchema: z.ZodType<unknown>` — structural check for
+  `SqliteReader`.
+- `parseWatcherConfig(input: unknown): IMessageWatcherConfig` — throws
+  `IMessageInvalidConfigError` on failure.
+- `parseAdapterConfig(input: unknown): IMessageAdapterConfig` — throws
+  `IMessageInvalidConfigError` on failure.
+
+## Implementation Notes
+
+The schemas use `z.custom` for the `SqliteReader` slot because the
+reader is a structural type — there is no Zod-expressible shape that
+captures every legal implementation. The check confirms the presence
+of a function-typed `open` member, which is enough to surface
+mistakes (passing a stray object or `null`) without inspecting the
+reader's behaviour. Issue arrays are projected through `toIssues`
+which strips Zod's internal symbols so the resulting record is safe
+to JSON-serialise.

+# `bunSqliteReader`
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+
+## Purpose
+
+Production-grade `SqliteReader` backed by Bun's built-in `bun:sqlite`
+driver. The reader is the single seam through which
+`IMessageWatcher` reaches Apple's `chat.db` SQLite database; replacing
+upstream's `require("bun:sqlite") as any` cast with a typed,
+swappable factory lets tests inject a reader pointing at a real temp
+chat.db without re-implementing the SQL layer.
+
+## Features
+
+- Lazy module resolution via `createRequire(import.meta.url)` — the
+  `bun:sqlite` import is not added to the static graph, so vite and
+  vitest do not attempt to resolve it on non-Bun runners during build
+  / type-check / lint passes.
+- Errors thrown from the load step or the `new Database(...)` call
+  are wrapped in `IMessageDbOpenFailedError` carrying the offending
+  path on `context.path`, so the watcher can surface a stable error
+  code to consumers.
+- Returns a `SqliteHandle` whose `execScript` member maps to
+  `Database.run` (Bun's bulk-SQL entry point) and whose `prepare`
+  member returns a `SqliteStatement` wrapping Bun's per-statement
+  `all` / `get` / `run` methods structurally — production and test
+  code share the exact same call shape.
+- Read-only by default: `open(path, { readonly: true })` opens the
+  database read-only as required for `~/Library/Messages/chat.db`,
+  while tests open with `readonly: false` to populate the fixture.
+
+## Usage: Basic
+
+```ts
+import { bunSqliteReader } from "@suaveplan/imessage-adapter";
+
+const handle = bunSqliteReader.open("/path/to/chat.db", { readonly: true });
+const rows = handle.prepare("SELECT ROWID FROM message LIMIT 1").all();
+handle.close();
+```
+
+## Usage: Advanced
+
+```ts
+import { createBunSqliteReader } from "@suaveplan/imessage-adapter";
+
+// Inject a custom loader (e.g. for vitest under WSL2 where bun:sqlite is
+// reached through a different worker bridge).
+const reader = createBunSqliteReader(() => require("bun:sqlite"));
+const handle = reader.open(path, { readonly: false });
+handle.execScript("CREATE TABLE foo (id INTEGER PRIMARY KEY)");
+```
+
+## API Reference
+
+- `bunSqliteReader: SqliteReader` — default reader, ready for
+  production wiring.
+- `createBunSqliteReader(loader?: BunSqliteLoader): SqliteReader` —
+  factory accepting a custom loader; defaults to a
+  `createRequire`-based one that resolves `bun:sqlite` against the
+  module's own URL.
+- `BunSqliteLoader = () => BunSqliteModule` — the loader contract.
+
+## Implementation Notes
+
+`createRequire(import.meta.url)` is the documented Node + Bun bridge
+for resolving CommonJS / built-in modules from ESM without statically
+declaring them. We use it because static `import "bun:sqlite"` would
+make vite resolve the specifier at build time and fail on non-Bun
+hosts (CI, lint). The `BunDatabase` interface is intentionally
+minimal — it only declares the methods the watcher actually calls,
+so changes to Bun's broader Database surface cannot bleed into the
+package.

+# `IMessageWatcher`
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+
+## Purpose
+
+Polls Apple's `~/Library/Messages/chat.db` SQLite database on a
+configurable interval, projects new rows into `ParsedIMessage`, and
+emits them on both a legacy `on/off` listener API and the typed
+`EventBus<IMessageWatcherEvents>` exposed as the public `bus` field.
+The watcher is the canonical ingress for any surface that
+wants to consume inbound macOS Messages traffic — adapter, router,
+or direct subscriber.
+
+## Features
+
+- Zod-validated config boundary (`pollIntervalMs > 0`,
+  `sinceDate: Date`, etc.) via `parseWatcherConfig` — invalid input
+  throws `IMessageInvalidConfigError` at construction time.
+- Injectable `SqliteReader` (defaults to the production
+  `bunSqliteReader`) so tests use a real `bun:sqlite` chat.db fixture
+  without mocks.
+- `start({ signal })` schedules polls every `pollIntervalMs`; the
+  signal stops the loop and emits a `stopped` event.
+- `poll({ signal })` runs one tick on demand; pre-aborted signals
+  throw `IMessagePollAbortedError`. Errors from explicit polls bubble
+  as `IMessageDbQueryFailedError`; errors from the internal scheduler
+  emit `error` on the bus and continue ticking (mirrors upstream
+  behaviour so a transient SQLite error doesn't tear down the loop).
+- Monotonic `lastRowId` cursor — only emits rows with `ROWID >
+  lastRowId`; advances even for filtered rows so the cursor doesn't
+  re-process them next tick. `getLastRowId()` / `setLastRowId(n)`
+  expose the cursor for consumers that want to persist resume state.
+- Filters: `includeFromMe: false` drops outgoing messages; non-empty
+  `chatFilter` restricts to specific `chat_identifier`s.
+- Four OTel instruments — `imessage.messages_emitted_total`,
+  `imessage.attachments_emitted_total`,
+  `imessage.poll_errors_total`, `imessage.poll_duration_ms` — wired
+  into every emit / error / tick.
+
+## Usage: Basic
+
+```ts
+import { IMessageWatcher } from "@suaveplan/imessage-adapter";
+
+const watcher = new IMessageWatcher({ pollIntervalMs: 5000 });
+const off = watcher.on("message", (msg) => console.log(msg.text));
+await watcher.start();
+// ...
+off();
+await watcher.stop();
+```
+
+## Usage: Advanced
+
+```ts
+import {
+    IMessageWatcher,
+    createChatDbFixture,
+    createBunSqliteReader,
+} from "@suaveplan/imessage-adapter";
+
+const reader = createBunSqliteReader();
+const fixture = createChatDbFixture(reader, "/tmp/chat.db");
+// ... populate fixture
+const watcher = new IMessageWatcher({
+    dbPath: "/tmp/chat.db",
+    sqliteReader: reader,
+    includeFromMe: true,
+    chatFilter: ["+15551234567"],
+});
+const controller = new AbortController();
+const parsed = await watcher.poll({ signal: controller.signal });
+```
+
+## API Reference
+
+- `new IMessageWatcher(config?: IMessageWatcherConfig)` — Zod-validates
+  at construction.
+- `bus: EventBus<IMessageWatcherEvents>` — typed event surface (`message`,
+  `error`, `started`, `stopped`).
+- `on(event, listener) => () => void` — legacy alias for `bus.on`.
+- `off(event, listener): void` — legacy alias for `bus.off`.
+- `start(opts?: { signal?: AbortSignal }): Promise<void>` — throws
+  `IMessageWatcherAlreadyRunningError` on double-start.
+- `stop(): Promise<void>` — throws `IMessageWatcherNotRunningError`
+  when called while not running.
+- `poll(opts?: { signal?: AbortSignal }): Promise<readonly ParsedIMessage[]>`.
+- `getLastRowId(): number` / `setLastRowId(rowId: number): void`.
+- `isRunning(): boolean`.
+
+## Implementation Notes
+
+The legacy `on/off` API delegates straight to the typed `EventBus`,
+which keeps the two surfaces in lockstep — there is no separate
+listener registry. The cursor advances inside the row loop *before*
+filters apply, so filtered rows are not re-fetched next tick. The
+scheduler-vs-explicit-poll error policy is asymmetric on purpose: a
+caller invoking `poll({ signal })` directly wants the error; the
+internal scheduler keeps ticking so a transient DB lock doesn't tear
+down the consumer.
