+# @suaveplan/storage-uri-plugin-bundle - Per-package bundle:// URI scheme plugin for @suaveplan/storage-uri. Universal; resolves bundle://<package-slug>/<rel-path> against an injectable rootUrl via fetch on every read. Read-only StorageLike shim, HTTP Range support with 200/206/416 disambiguation, AbortSignal propagation, optional in-memory LRU, full OpenTelemetry surface.
+
+Per-package `bundle://` URI scheme for `@suaveplan/storage-uri`.
+
+`bundle://<package-slug>/<rel-path>` lets a consuming package ship binary
+assets — impulse responses, sample fonts, reference images, fixture
+bundles — alongside its npm tarball and resolve them through the existing
+`storage-uri` ecosystem. The plugin is universal: zero `node:fs`,
+zero browser-only branches, every read goes through an injectable
+`FetchLike` against `new URL(encodedRelPath, rootUrl)`. `file:`, `https:`,
+`http:`, `data:`, `blob:`, and bundler-virtual schemes all flow through
+the same fetch surface.

+
+## Quick start — register one plugin per consuming package
+
+```ts
+import { createStorageUriResolver } from "@suaveplan/storage-uri";
+import { bundleUriPlugin } from "@suaveplan/storage-uri-plugin-bundle";
+
+const resolver = createStorageUriResolver({});
+
+// In each consuming package's `register()`:
+resolver.register(
+    bundleUriPlugin({
+        packageSlug: "audio-ir-room-plugin-club",
+        rootUrl: new URL("./", import.meta.url),
+    })
+);
+
+const bytes = await resolver.read(
+    "bundle://audio-ir-room-plugin-club/assets/club.wav"
+);
+```
+
+## Bundler composition — flatten assets to a CDN URL
+
+Vite, esbuild, and webpack all rewrite `new URL("./assets/x.wav", import.meta.url)`
+at build time. Register the plugin with a `rootUrl` pointing at the
+flattened asset directory and the runtime fetch transparently lands on
+the bundler-produced URL:
+
+```ts
+// Vite / esbuild / webpack
+import assetsRoot from "./assets/?url"; // → flattened bundle URL
+
+bundleUriPlugin({
+    packageSlug: "audio-ir-room-plugin-club",
+    rootUrl: assetsRoot, // bundler-rewritten string is fine
+});
+```
+
+In production this becomes a real HTTPS URL — `bundle://` still resolves
+the relative path inside that root through `fetch`, and the OTel surface
+classifies the root as `root_kind="http"`.
+
+## Node users + `file://` roots
+
+Node's global `fetch` (undici, all releases through Node 24) does NOT
+support `file:` URLs. If your `rootUrl` is a `file://` URL and you are
+running on Node, the default `globalThis.fetch` wiring will reject on
+the first `get`. The package ships a dedicated server-tier adapter at
+the `./node-fetch` subpath that closes the gap:
+
+```ts
+import { bundleUriPlugin } from "@suaveplan/storage-uri-plugin-bundle";
+import { nodeFileFetch } from "@suaveplan/storage-uri-plugin-bundle/node-fetch";
+
+const plugin = bundleUriPlugin({
+    packageSlug: "audio-ir-room-plugin-club",
+    rootUrl: new URL("./assets/", import.meta.url),
+    fetch: nodeFileFetch, // ← required on Node when rootUrl is file://
+});
+```
+
+`nodeFileFetch` reads `file:` URLs via `node:fs/promises`, returns a
+real `Response` with `content-length` + `last-modified`, honours `HEAD`
+and `Range: bytes=<start>-<end>` (including open-ended `bytes=10-`), and
+threads `init.signal` into the underlying read. Any non-`file:` URL
+falls through to `globalThis.fetch`, so a single adapter handles both
+local-disk and CDN roots without branching at the call site.
+
+Bun's native `fetch` already supports `file:` URLs — Bun consumers can
+keep using the default `globalThis.fetch` wiring. The subpath import
+exists so the package's default export stays universal-pure (no
+`node:*` imports leak into browser, Cloudflare Workers, Deno, or React
+Native builds).
+
+## Composition — front the plugin with `storage-plugin-cache`
+
+```ts
+import { cachedStorage } from "@suaveplan/storage-plugin-cache";
+import { MemoryCache } from "@suaveplan/cache";
+
+const cache = new MemoryCache<Uint8Array>();
+const cached = cachedStorage(plugin.adapter, { cache, namespace: "bundle" });
+```
+
+## Error codes
+
+`BUNDLE_URI.PACKAGE_MISMATCH`, `PATH_TRAVERSAL`, `READ_ONLY`,
+`NOT_FOUND`, `INVALID_URI`, `FETCH_FAILED`, `RANGE_INVALID`,
+`RANGE_UNSUPPORTED`, `ABORTED` — all reachable from a real call site
+exercised by the test suite.
+
+## OpenTelemetry
+
+- `bundle_uri.op_duration_ms{op, root_kind, outcome}` histogram.
+- `bundle_uri.reads_total{root_kind, outcome}` counter.
+- `bundle_uri.errors_total{root_kind, code}` counter.
+- `bundle_uri.range_fallback_total{root_kind}` counter.
+- `bundle_uri.cache_hits_total{root_kind}` /
+  `bundle_uri.cache_misses_total{root_kind}` counters.
+- Per-op span on the `@suaveplan/storage-uri-plugin-bundle` tracer with
+  `bundle.package`, `bundle.rel_path` (query-stripped + 256-char clip),
+  `bundle.root_kind` (`file | http | data | blob | other`),
+  `bundle.outcome` attributes.
+
+Inject a `MeterProvider` with `setBundleUriMeterProvider(provider)` then
+`resetInstruments()` to rebind.

+# AbortSignal helpers
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+
+## Purpose
+
+`abort.ts` declares the two helpers every read path consumes to honour an
+`AbortSignal`: `ensureNotAborted` short-circuits an already-aborted signal
+into a `BUNDLE_URI.ABORTED` rejection *before* any fetch is dispatched,
+and `wrapAbortError` converts a mid-flight `AbortError` into a structured
+`BundleUriError` carrying the original error on `cause` so retry and
+circuit-breaker classifiers can distinguish caller-initiated cancellation
+from transport failure.
+
+The helpers are intentionally stateless and side-effect free — they accept
+the per-call diagnostic context (URI, slug, rel-path, root-kind) as a
+plain object so the same helper handles every operation (`get`, `exists`,
+`getMetadata`, `getPartial`, `createReadStream`) without per-op branches.
+
+## Features
+
+- Pre-fetch short-circuit when `signal.aborted === true`.
+- Mid-flight `AbortError` detection by name (works against both
+  `DOMException("AbortError")` and `Error{name:"AbortError"}` shapes).
+- Original error preserved on `cause` for the structured-error chain.
+- Zero allocation when the signal is absent or not aborted.
+
+## Usage: Basic
+
+```ts
+import {
+    ensureNotAborted,
+    wrapAbortError,
+} from "@suaveplan/storage-uri-plugin-bundle";
+
+ensureNotAborted(signal, {
+    uri: "bundle://x/a",
+    packageSlug: "x",
+    relPath: "a",
+    rootKind: "http",
+});
+```
+
+## Usage: Advanced
+
+```ts
+try {
+    return await fetchImpl(url, { signal });
+} catch (cause) {
+    const wrapped = wrapAbortError(cause, {
+        uri,
+        packageSlug,
+        relPath,
+        rootKind,
+    });
+    if (wrapped) throw wrapped;
+    throw cause;
+}
+```
+
+## API Reference
+
+- `AbortContext` — `{ uri, packageSlug, relPath, rootKind }`.
+- `ensureNotAborted(signal, ctx)` — throws if `signal.aborted`.
+- `wrapAbortError(cause, ctx)` — returns a `BundleUriError` for abort
+  causes, `undefined` otherwise.
+
+## Implementation Notes
+
+`isAbortError` does a `typeof object` plus `name === "AbortError"` check
+rather than `instanceof DOMException` so the helper works under Node, Bun,
+and browsers without a platform-specific dependency. The `signal.reason`
+is preserved on `cause` for the pre-aborted path so consumers can surface
+why the caller cancelled (`signal.reason` may be any value per the
+WHATWG spec).

+# UriLruCache
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+
+## Purpose
+
+`cache.ts` declares the optional in-memory LRU used by the storage shim
+when a caller passes `options.cache = { maxBytes }`. The cache is keyed
+by the full URI string, holds raw `Uint8Array` bodies, and evicts oldest
+entries first until the cumulative byte total is at or below the configured
+ceiling. The implementation is intentionally minimal — just enough surface
+for the `get` / `set` / `has` triad the shim needs.
+
+The shim defaults to OFF. When the LRU is enabled, every successful `get`
+result is inserted; subsequent `get`s of the same URI return the cached
+bytes without invoking the injected `FetchLike`. Writes are not relevant
+(bundles are immutable, every write throws `READ_ONLY` upstream of the
+cache).
+
+## Features
+
+- O(1) `get`/`set`/`has` via the underlying `Map`.
+- LRU recency refresh on `get` (delete + re-insert at tail).
+- Byte-bounded eviction policy — oldest-first until
+  `currentBytes <= maxBytes`.
+- Single-entry oversize is rejected silently (the entry is not inserted
+  and no eviction loop fires) so a runaway 500 MB payload cannot flush
+  the entire cache.
+- `bytes` / `size` accessors for diagnostic and test inspection.
+
+## Usage: Basic
+
+```ts
+import { UriLruCache } from "@suaveplan/storage-uri-plugin-bundle";
+
+const cache = new UriLruCache(1024);
+cache.set("bundle://x/a", new Uint8Array(512));
+cache.set("bundle://x/b", new Uint8Array(512));
+cache.get("bundle://x/a"); // → Uint8Array (and refresh recency)
+cache.set("bundle://x/c", new Uint8Array(512));
+cache.has("bundle://x/b"); // → false (evicted as oldest)
+```
+
+## Usage: Advanced
+
+```ts
+import { UriLruCache } from "@suaveplan/storage-uri-plugin-bundle";
+
+const cache = new UriLruCache(100);
+cache.set("k1", new Uint8Array(50));
+cache.set("k2", new Uint8Array(50));
+cache.set("k3", new Uint8Array(50));
+console.log(cache.size, cache.bytes); // → 2 100
+console.log(cache.has("k1")); // → false (oldest evicted)
+```
+
+## API Reference
+
+- `new UriLruCache(maxBytes)` — construct an empty cache with the
+  byte ceiling.
+- `get(key): Uint8Array | undefined` — refresh recency and return.
+- `set(key, value): void` — insert and evict to satisfy the ceiling.
+- `has(key): boolean` — non-mutating presence check.
+- `size: number` — entry count.
+- `bytes: number` — cumulative byte total.
+
+## Implementation Notes
+
+The class delegates everything to a plain `Map`. JavaScript `Map`
+preserves insertion order, so `map.keys().next().value` returns the
+oldest key — exactly the LRU candidate. The recency refresh on `get`
+is a delete + re-insert; the cost is O(1). Cached buffers are shared
+references — callers must NOT mutate a returned `Uint8Array` in place
+or future cache hits will surface the mutation. The shim guarantees
+immutability by treating cache results as read-only, which is the same
+invariant the entire `bundle://` contract enforces upstream.

+# BUNDLE_URI error codes
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+
+## Purpose
+
+`error-codes.ts` declares the canonical registry of every error code raised by
+`@suaveplan/storage-uri-plugin-bundle` and the `BundleUriError` class that
+carries those codes through the structured-error pipeline. Every code listed
+here is reachable from a real call site in the package and exercised by an
+explicit `it(...)` in the test suite — unused codes are a CI failure per
+`AGENTS.md §2c`.
+
+The class extends `SuaveplanError` so that traces, redaction, span events,
+and the `walkCauses` chain work uniformly with the rest of the project. The
+discriminants (`uri`, `scheme`, `packageSlug`, `relPath`, `rootKind`, `op`,
+`actual`, `httpStatus`, `offset`, `length`) surface the dimensions that
+operators most commonly filter dashboards on without needing to parse free
+text out of `message`.
+
+## Features
+
+- Frozen `BUNDLE_URI_CODES` record produced by `defineCodes` — type-narrowed
+  values, exhaustive registry inferred by TypeScript.
+- `BundleUriError` subclass with a typed `code` plus nine optional structured
+  discriminants for granular diagnostics.
+- All nine codes (`PACKAGE_MISMATCH`, `PATH_TRAVERSAL`, `READ_ONLY`,
+  `NOT_FOUND`, `INVALID_URI`, `FETCH_FAILED`, `RANGE_INVALID`,
+  `RANGE_UNSUPPORTED`, `ABORTED`) reachable from real call sites.
+- `BundleUriRootKind` enum aligned with the resolution-matrix `root_kind`
+  span attribute (`file` | `http` | `data` | `blob` | `other`).
+
+## Usage: Basic
+
+```ts
+import {
+    BUNDLE_URI_CODES,
+    BundleUriError,
+} from "@suaveplan/storage-uri-plugin-bundle/error-codes/error-codes";
+
+throw new BundleUriError(BUNDLE_URI_CODES.NOT_FOUND, "asset missing", {
+    uri: "bundle://my-pkg/assets/x.wav",
+    packageSlug: "my-pkg",
+    relPath: "assets/x.wav",
+    rootKind: "http",
+});
+```
+
+## Usage: Advanced
+
+```ts
+import {

+## API Reference
+
+- `BUNDLE_URI_CODES` — frozen record `{ <REASON>: "BUNDLE_URI.<REASON>" }`.
+- `BundleUriErrorCode` — literal-typed union of `BUNDLE_URI.*` strings.
+- `BundleUriRootKind` — `"file" | "http" | "data" | "blob" | "other"`.
+- `BundleUriErrorOptions` — `SuaveplanErrorOptions` plus optional `uri`,
+  `scheme`, `packageSlug`, `relPath`, `rootKind`, `op`, `actual`,
+  `httpStatus`, `offset`, `length`.
+- `BundleUriError` — `SuaveplanError<BundleUriErrorCode>` with every option
+  re-surfaced as a typed public-readonly field.
+
+## Implementation Notes
+
+The class name is captured in `Error.captureStackTrace` so the stack frame
+points at the throw site, not at the base-class constructor. Discriminants
+are assigned individually (rather than spread) so that
+`exactOptionalPropertyTypes` is satisfied without leaking `undefined` keys
+into JSON serialisation. The codes registry is constructed once at module
+load through `Object.freeze`, matching the convention in every other
+`defineCodes` consumer.

+# bundleUriPlugin
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+
+## Purpose
+
+`factory.ts` is the public entry point for `@suaveplan/storage-uri-plugin-bundle`.
+`bundleUriPlugin(options)` validates the supplied option bag through
+`BundleUriPluginOptionsSchema`, normalises `rootUrl` to a trailing-slash
+`URL` instance, defaults `fetch` to `globalThis.fetch.bind(globalThis)`
+and `clock` to `Date.now`, then constructs a `UriPlugin` whose `scheme`
+is `"bundle"`, whose `adapter` is a `BundleStorageShim`, and whose
+`parse` / `build` are bound to the validated options.
+
+Each consuming package calls the factory once from its own `register()`
+hook and contributes its plugin to a shared `StorageUriResolver`. The
+slug parameter scopes one plugin to one package — calling the resolver
+with `bundle://<other-pkg>/x` surfaces `PACKAGE_MISMATCH` at `parse`
+rather than producing a silent mis-route.
+
+## Features
+
+- Zod-validated option bag — strict; unknown keys rejected.
+- Slug regex enforced at construction (`^@?[a-z0-9][a-z0-9._/-]{0,127}$`).
+- `rootUrl` normalised to `URL`; trailing-slash pathname required.
+- Default `fetch` resolution via `globalThis.fetch` with a clear error
+  when no global is available (Node ≤ 17 / hostile sandboxes).
+- Returned plugin satisfies `runUriPluginConformance`.
+
+## Usage: Basic
+
+```ts
+import { bundleUriPlugin } from "@suaveplan/storage-uri-plugin-bundle";
+
+const plugin = bundleUriPlugin({
+    packageSlug: "audio-ir-room-plugin-club",
+    rootUrl: new URL("./", import.meta.url),
+});
+resolver.register(plugin);
+```
+
+## Usage: Advanced
+
+```ts
+import { bundleUriPlugin } from "@suaveplan/storage-uri-plugin-bundle";
+
+const plugin = bundleUriPlugin({
+    packageSlug: "@suaveplan/font-subset",
+    rootUrl: "https://cdn.example/font-subset/",
+    fetch: signedFetch,
+    cache: { maxBytes: 5_000_000 },
+});
+```
+
+## API Reference
+
+- `bundleUriPlugin(options): UriPlugin` — entry point.
+- `validateOptions(options): ResolvedBundleUriPluginOptions` — exported
+  for tests; throws `BundleUriError(BUNDLE_URI.INVALID_URI)` on failure.
+
+## Implementation Notes
+
+`validateOptions` is exported separately so the test suite can exercise
+the validation branches without round-tripping through the full plugin
+construction. The trailing-slash check is performed after `URL`
+normalisation so a `string` input like `"file:///pkgs/x/assets"`
+surfaces as `INVALID_URI` rather than being silently amended — caller
+mistakes are loud. `resolveGlobalFetch` is the only place that touches
+`globalThis.fetch` so injecting a stub in tests is a one-line change.

+# nodeFileFetch — Node `file://` adapter
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+
+## Purpose
+
+`nodeFileFetch` is a server-tier `FetchLike` that closes a real gap in
+Node's global `fetch`: undici (the engine backing `globalThis.fetch` in
+every Node release through 24) refuses `file:` URLs outright. Consumers
+that point `bundleUriPlugin` at a local-disk `rootUrl` on Node therefore
+cannot use the default plugin wiring — the first `get` rejects with a
+transport error. This adapter is the supported fix.
+
+The function is exposed at the dedicated `./node-fetch` subpath so the
+package's default export stays universal-pure (no `node:*` imports
+from `src/index.ts`). Node consumers opt into the adapter with one
+explicit import, browser/Bun/edge consumers continue to use the default
+`globalThis.fetch` wiring untouched.
+
+## Features
+
+- WHATWG `fetch` shape — assignable to `@suaveplan/types.FetchLike` and
+  to the plugin's `options.fetch` slot with no cast.
+- `file:` URL → `node:fs/promises.readFile` round trip with a real
+  `Response` (status 200, `content-length`, `last-modified`).
+- `HEAD` short-circuit returns headers only (no buffer read).
+- `Range: bytes=<start>-<end>` honoured — returns `206 Partial Content`
+  with `content-range`. Empty end (`bytes=10-`) is interpreted as
+  "through end of file", matching RFC 7233. Out-of-range requests return
+  `416 Range Not Satisfiable` with `content-range: bytes */<size>`.
+- `init.signal` threaded into `fs.readFile({ signal })`. A pre-aborted
+  signal short-circuits the read and rejects with an `AbortError` (or
+  the signal's `reason` if provided) so the plugin's abort pipeline can
+  rewrap it as `BUNDLE_URI.ABORTED`.
+- Non-`file:` URLs delegate to `globalThis.fetch`, so a single adapter
+  instance handles both local-disk and CDN roots without branching at
+  the call site.
+- Missing path or non-file inode (directory, symlink loop) returns
+  `404 Not Found`, matching the rest of the plugin's NOT_FOUND mapping.
+
+## Usage: Basic
+
+```ts
+import { bundleUriPlugin } from "@suaveplan/storage-uri-plugin-bundle";
+import { nodeFileFetch } from "@suaveplan/storage-uri-plugin-bundle/node-fetch";
+
+const plugin = bundleUriPlugin({
+    packageSlug: "audio-ir-room-plugin-club",
+    rootUrl: new URL("./assets/", import.meta.url),
+    fetch: nodeFileFetch,
+});
+
+const bytes = await plugin.adapter.get("club.wav");
+```
+
+## Usage: Advanced
+
+```ts
+import { bundleUriPlugin } from "@suaveplan/storage-uri-plugin-bundle";
+import { nodeFileFetch } from "@suaveplan/storage-uri-plugin-bundle/node-fetch";
+
+// Range read — plugin issues "Range: bytes=10-19", adapter answers 206
+// with the 10-byte slice, plugin returns it verbatim.
+const plugin = bundleUriPlugin({
+    packageSlug: "x",
+    rootUrl: new URL("file:///pkgs/x/assets/"),
+    fetch: nodeFileFetch,
+});
+
+const controller = new AbortController();
+const slice = await plugin.adapter.getPartial(
+    "club.wav",
+    10,
+    10,
+    controller.signal
+);
+// controller.abort() before resolution → BUNDLE_URI.ABORTED.
+```
+
+## API Reference
+
+- `nodeFileFetch(input, init?): Promise<Response>` — `FetchLike`. For
+  `file:` URLs reads the path through `node:fs/promises`; for any other
+  scheme delegates to `globalThis.fetch`.
+
+## Implementation Notes
+
+The adapter never throws for HTTP-shaped problems — missing files become
+`404`, range overflows become `416`, etc. — because the calling plugin
+already owns the status → `BUNDLE_URI.*` mapping and expects a real
+`Response` shape. The one exception is `AbortSignal`: a pre-aborted
+signal throws synchronously (before the `stat` round trip) so the
+plugin's `ensureNotAborted` upstream check is symmetric with the
+adapter's downstream check. Mid-flight aborts propagate as the native
+`AbortError` that `fs.readFile({ signal })` raises; the plugin's
+`wrapAbortError` catches that and rewrites it to `BUNDLE_URI.ABORTED`.
+
+Range parsing tolerates both `bytes=10-19` (closed interval) and
+`bytes=10-` (open through EOF) per RFC 7233 §2.1. End values past EOF
+are clamped to `size-1` so a caller asking for `bytes=10-` against a
+20-byte file gets a 10-byte slice + `content-range: bytes 10-19/20`. A
+single regex match runs per call — no allocation past the `Headers`
+construction the calling code already paid for.
+
+`node:fs/promises` is the only `node:*` import. The module sits at the
+`./node-fetch` subpath so universal consumers never pull it through the
+default barrel; tree-shaking and tier checks both stay green.

+/**
+ * Server-tier `FetchLike` that resolves `file://` URLs through `node:fs`.
+ *
+ * Node's undici-backed global `fetch` does not support `file:` URLs (and
+ * Node 24 still does not, despite the original design note's optimism).
+ * This adapter closes that gap: when invoked with a `file:` URL it reads
+ * the corresponding path with `node:fs/promises` and returns a real
+ * `Response` shaped the same way the universal plugin code expects.
+ *
+ * Non-`file:` URLs fall through to `globalThis.fetch`, so consumers can
+ * configure a single adapter for both `file://` package-local roots and
+ * `https://` CDN roots without branching.
+ *
+ * Honours:
+ * - `HEAD` (returns `200` with `content-length` + `last-modified` only).
+ * - `Range: bytes=<offset>-<end>` (returns `206 Partial Content` with the
+ *   slice; an empty end is interpreted as "through end of file").
+ * - `init.signal` — threaded into `node:fs/promises.readFile`. A pre-aborted
+ *   signal short-circuits before the read.
+ *
+ * @example
+ * ```ts
+ * import { bundleUriPlugin } from "@suaveplan/storage-uri-plugin-bundle";
+ * import { nodeFileFetch } from "@suaveplan/storage-uri-plugin-bundle/node-fetch";
+ *
+ * const plugin = bundleUriPlugin({
+ *     packageSlug: "audio-ir-room-plugin-club",
+ *     rootUrl: new URL("./assets/", import.meta.url),
+ *     fetch: nodeFileFetch,
+ * });

+# OpenTelemetry wiring
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+
+## Purpose
+
+`otel.ts` exposes the tracer, meter, and instrument bag that every read
+path in `@suaveplan/storage-uri-plugin-bundle` records against. It mirrors
+the convention used by `@suaveplan/storage-uri/otel` and
+`@suaveplan/storage-plugin-cache/otel`: lazy instrument acquisition,
+test-injectable `MeterProvider`, and a single `recordOp` entry point that
+emits the histogram, the success/error counter, and the per-op span in one
+call so the call site never forgets one of the three.
+
+The module also carries the small helpers that the rest of the package
+relies on for span-attribute hygiene: `sanitiseRelPathAttr` strips
+query strings and truncates to 256 chars, and `classifyRootKind` maps
+a `URL` to the `file | http | data | blob | other` label used on every
+span and counter.
+
+## Features
+
+- `bundle_uri.op_duration_ms{op, root_kind, outcome}` histogram.
+- `bundle_uri.reads_total{root_kind, outcome}` counter.
+- `bundle_uri.errors_total{root_kind, code}` counter.
+- `bundle_uri.range_fallback_total{root_kind}` counter.
+- `bundle_uri.cache_hits_total{root_kind}` and
+  `bundle_uri.cache_misses_total{root_kind}` counters.
+- Per-op span on the `@suaveplan/storage-uri-plugin-bundle` tracer with
+  `bundle.package`, `bundle.rel_path`, `bundle.root_kind`,
+  `bundle.outcome` attributes.
+- `setBundleUriMeterProvider(provider)` + `resetInstruments()` for
+  deterministic test injection.
+
+## Usage: Basic
+
+```ts
+import { recordOp } from "@suaveplan/storage-uri-plugin-bundle";
+
+recordOp({
+    op: "get",
+    rootKind: "http",
+    outcome: "success",
+    durationMs: 12,
+    packageSlug: "my-pkg",
+    relPath: "assets/x.wav",
+});
+```
+
+## Usage: Advanced
+
+```ts
+import {
+    setBundleUriMeterProvider,
+    resetInstruments,
+} from "@suaveplan/storage-uri-plugin-bundle";
+import { MeterProvider } from "@opentelemetry/sdk-metrics";
+
+const provider = new MeterProvider({});
+setBundleUriMeterProvider(provider);
+resetInstruments();
+// …run instrumented code, then drain `provider` to read observations.
+```
+
+## API Reference
+
+- `getInstruments(force?)` — lazy-build the bag; `force=true` rebuilds.
+- `setBundleUriMeterProvider(provider | undefined)` — test injection.
+- `resetInstruments()` — drop the cached bag.
+- `recordOp(input)` — one-call emission of histogram + counter + span.
+- `recordRangeFallback(rootKind)` — increment fallback counter.
+- `recordCacheHit(rootKind)` / `recordCacheMiss(rootKind)` —
+  cache-path counters.
+- `sanitiseRelPathAttr(relPath)` — strip query + truncate to 256 chars.
+- `classifyRootKind(rootUrl)` — `URL` → `BundleUriRootKind`.
+- `BundleUriOp`, `BundleUriOutcome`, `BundleUriInstruments`,
+  `RecordOpInput` — supporting types.
+
+## Implementation Notes
+
+The instrument bag is held in a module-private `let` so the same
+instruments persist across calls. `resetInstruments` is the test-only
+escape hatch that drops the cache so the next `getInstruments` rebinds
+against the freshly-installed `MeterProvider`. The 256-char clip is
+applied *after* the query strip — query-string lengths are not counted
+against the attribute size budget. `classifyRootKind` is a `switch` over
+`URL.protocol` (which always ends with `:`); the default case covers
+bundler-virtual schemes (`virtual:`, `~asset:`, `\0…`) so coverage
+includes the `"other"` branch.

+# parse / build
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+
+## Purpose
+
+`parse.ts` enforces the `bundle://<package-slug>/<rel-path>` grammar
+declared in `design.md §1` and rejects every malformed or escaping input
+with a typed `BundleUriError`. It delegates RFC 3986 component splitting
+to `parseUri` from `@suaveplan/storage-uri` (so length, NUL, whitespace,
+and scheme-syntax checks are shared with every other URI plugin) and
+layers per-plugin slug enforcement and three-pass path-traversal
+prevention on top.
+
+The inverse `build(key, options, meta?)` re-serialises a key plus optional
+meta into a canonical `bundle://` URI. The pair satisfies the
+round-trip contract `parse(build(key, opts)) === { key, meta }`.
+
+## Features
+
+- Lowercased scheme match per RFC 3986 §3.1 (delegated to `parseUri`).
+- Slug enforcement at the boundary — mis-routed URIs surface as
+  `PACKAGE_MISMATCH` before any I/O.
+- Three-pass traversal prevention: raw `..` rejection, post-decode
+  `..` rejection, defensive URL-resolve `pathname.startsWith` check.
+- Pass 3 is skipped for non-hierarchical `data:` / `blob:` roots, where
+  URL resolution is meaningless (single-resource model per
+  `design.md §2`).
+- `build` round-trips through `parse` for every key the plugin accepts.
+
+## Usage: Basic
+
+```ts
+import { parse, build } from "@suaveplan/storage-uri-plugin-bundle";
+
+const opts = {
+    packageSlug: "my-pkg",
+    rootUrl: new URL("file:///pkgs/my-pkg/"),
+    fetch: globalThis.fetch,
+    clock: () => Date.now(),
+};
+const parsed = parse("bundle://my-pkg/assets/x.wav", opts);
+// → { key: "assets/x.wav", meta: { packageSlug: "my-pkg" } }
+const uri = build("assets/x.wav", opts);
+// → "bundle://my-pkg/assets/x.wav"
+```
+
+## Usage: Advanced
+
+```ts
+import { parse } from "@suaveplan/storage-uri-plugin-bundle";
+
+try {
+    parse("bundle://my-pkg/%2E%2E/etc/passwd", opts);
+} catch (err) {
+    // err.code === "BUNDLE_URI.PATH_TRAVERSAL"
+    // err.relPath === "%2E%2E/etc/passwd"
+}
+```
+
+## API Reference
+
+- `parse(uri, options): BundleParsed` — `{ key, meta: { packageSlug } }`
+  on success; `BundleUriError` on failure.
+- `build(key, options, meta?): string` — canonical `bundle://` URI.
+- `BundleParsed` — `{ key, meta: { packageSlug } }`.
+
+## Implementation Notes
+
+`parseUri` is consumed via the package barrel to keep the dependency
+graph shallow. Pass 1 uses a tight regex `/(^|\/)\.\.(\/|$)/` rather
+than splitting on `/` and scanning segments — same semantics, no array
+allocation. Pass 2 catches `decodeURIComponent` throwing (malformed
+percent-encoding such as `%2`) and rethrows as `INVALID_URI` with the
+underlying `URIError` on `cause`. Pass 3 anchors the resolved
+pathname against `rootUrl.pathname` (which always ends with `/` by the
+factory's normalisation), so a hypothetical input that slips both
+earlier passes still cannot escape.

+# Range read primitives
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+
+## Purpose
+
+`range.ts` implements the building blocks the storage shim uses to issue
+HTTP `Range` requests and disambiguate the three possible upstream
+responses: `206 Partial Content` (range honoured, return body verbatim),
+`200 OK` (server ignored the header — slice client-side and increment
+the fallback counter), and `416 Range Not Satisfiable` (raise
+`BUNDLE_URI.RANGE_INVALID`). Offset/length validation happens before
+any fetch so a malformed call is cheap and the OTel counter for failed
+ranges is not polluted with caller-side mistakes.
+
+The module is intentionally fetch-agnostic — `sliceForRange` accepts a
+status code plus a buffered body, so the call site decides how the
+fetch is dispatched and how the `Range` header is composed. That keeps
+the file under 300 lines and lets the shim unit-test the slicing
+matrix without spinning a server.
+
+## Features
+
+- `validateRange(offset, length, ctx)` — integer + bounds check,
+  throws `RANGE_INVALID` on violation without dispatching fetch.
+- `buildRangeHeader(offset, length)` — canonical
+  `bytes=<offset>-<offset+length-1>` value.
+- `sliceForRange(status, body, offset, length, ctx, rootKind)` —
+  three-branch disambiguation, returns `{ bytes, fallback }`.
+- Sum-overflow guard on `offset + length` against
+  `Number.MAX_SAFE_INTEGER`.
+
+## Usage: Basic
+
+```ts
+import {
+    validateRange,
+    buildRangeHeader,
+    sliceForRange,
+} from "@suaveplan/storage-uri-plugin-bundle";
+
+validateRange(0, 10, { uri, relPath });
+const header = buildRangeHeader(0, 10); // "bytes=0-9"
+const { bytes, fallback } = sliceForRange(
+    206,
+    body,
+    0,
+    10,
+    { uri, relPath },
+    "http"
+);
+```
+
+## Usage: Advanced
+
+```ts
+import { sliceForRange } from "@suaveplan/storage-uri-plugin-bundle";
+
+// Server ignored the Range header and returned 200 — slice locally
+// and increment the fallback counter.
+const { bytes, fallback } = sliceForRange(
+    200,
+    fullBody,
+    10,
+    10,
+    { uri, relPath },
+    "http"
+);
+if (fallback) recordRangeFallback("http");
+```
+
+## API Reference
+
+- `RangeValidationCtx` — `{ uri, relPath }`.
+- `RangeOutcome` — `{ bytes, fallback }`.
+- `validateRange(offset, length, ctx)` — throws on bad input.
+- `buildRangeHeader(offset, length): string`.
+- `sliceForRange(status, body, offset, length, ctx, rootKind): RangeOutcome`.
+
+## Implementation Notes
+
+`validateRange` rejects non-integer offsets and lengths, negative
+offsets, zero / negative lengths, and the sum overflow that would
+otherwise wrap around past `Number.MAX_SAFE_INTEGER`. The 200-fallback
+slice is clamped to `body.byteLength` so a caller asking for a slice
+beyond EOF receives an undersized (or empty) `Uint8Array` rather than a
+throw — matching the WHATWG `Response.arrayBuffer` then `Uint8Array#slice`
+behaviour every fetch consumer already expects. 416 is the only
+non-2xx status the slicer rewraps; other non-2xx statuses are the
+shim's responsibility (`NOT_FOUND`, `FETCH_FAILED`).

+# Storage-shim fetch helpers
+
+## Purpose
+
+`storage-shim.fetch.ts` carries the two cross-cutting helpers every
+storage-shim method uses: `safeFetch` dispatches an injected `FetchLike`
+and rewraps a thrown cause into the right `BundleUriError`
+(`ABORTED` for `AbortError`, `FETCH_FAILED` for anything else), and
+`assertSuccess` maps a non-2xx response status to a typed error
+(`NOT_FOUND` for 404/410, `FETCH_FAILED` for everything else).
+
+Splitting these out keeps `storage-shim.ts` under the 300-line ceiling
+without introducing test-only mocking seams — both helpers are exercised
+through real fetch fixtures from the main shim tests.
+
+## Features
+
+- `safeFetch` — single try/catch wrapping the fetch dispatch.
+- `assertSuccess` — three-branch status mapping (2xx, 404/410, other).
+- `cleanRelPathForAttr` — strip query string for span attributes.
+- `FetchContext` value type carrying every discriminant the helpers
+  surface on thrown errors.
+
+## Usage: Basic
+
+```ts
+import {
+    safeFetch,
+    assertSuccess,
+} from "@suaveplan/storage-uri-plugin-bundle";
+
+const res = await safeFetch(fetchImpl, url, {}, ctx, "GET");
+assertSuccess(res, ctx, "GET");
+const body = new Uint8Array(await res.arrayBuffer());
+```
+
+## Usage: Advanced
+
+```ts
+const init: RequestInit = signal ? { signal, method: "HEAD" } : { method: "HEAD" };
+const res = await safeFetch(fetchImpl, url, init, ctx, "HEAD");
+if (res.status === 404) return false;
+assertSuccess(res, ctx, "HEAD");
+```
+
+## API Reference
+
+- `safeFetch(fetchImpl, url, init, ctx, description): Promise<Response>`.
+- `assertSuccess(res, ctx, description): void` — throws on non-2xx.
+- `cleanRelPathForAttr(key): string` — strips query suffix.
+- `FetchContext` — `{ uri, packageSlug, relPath, rootKind }`.
+
+## Implementation Notes
+
+`safeFetch` is intentionally async so the awaited rejection is captured
+by the surrounding `try`/`catch`; a sync wrapper would let the rejection
+bubble synchronously and skip the `wrapAbortError` branch. The
+`description` parameter is the operation name embedded in thrown error
+messages (`"GET fetch rejected"`, `"HEAD fetch rejected"`,
+`"RANGE fetch rejected"`) so operators can grep diagnostics for the
+originating call site. `cleanRelPathForAttr` is shared by every shim
+method to keep span attributes free of query-string secrets.

+# HEAD-backed exists and getMetadata
+
+## Purpose
+
+`storage-shim.head.ts` implements the two HEAD-routed methods of the
+bundle storage shim. `performExists` returns a boolean by mapping
+2xx → true, 404/410 → false, anything else → `FETCH_FAILED`.
+`performGetMetadata` parses the four headers the `StatResult` contract
+recognises (`content-length`, `content-type`, `etag`,
+`last-modified`) and returns a sparse object that only carries the keys
+the upstream actually provided.
+
+The split keeps the main shim under the 300-line limit and lets the
+HEAD pipeline be tested in isolation against a real `node:http`
+fixture server.
+
+## Features
+
+- 2xx / 404-410 / other-status disambiguation for `exists`.
+- Strict numeric parse on `content-length` (regex
+  `^\d+$` — rejects negative or floating-point garbage).
+- Date-validity check on `last-modified` — invalid `Date` is dropped
+  rather than surfaced as `Invalid Date`.
+- Sparse `StatResult` — only present headers appear on the result so
+  `exactOptionalPropertyTypes` consumers never see `undefined` keys.
+
+## Usage: Basic
+
+```ts
+import {
+    performExists,
+    performGetMetadata,
+} from "@suaveplan/storage-uri-plugin-bundle";
+
+const ok = await performExists({ options, url, signal, ctx });
+const meta = await performGetMetadata({ options, url, signal, ctx });
+```
+
+## Usage: Advanced
+
+```ts
+const meta = await performGetMetadata({ options, url, signal: undefined, ctx });
+if (meta.size !== undefined && meta.size > 10_000_000) {
+    throw new Error("asset too large");
+}
+if (meta.lastModified !== undefined) cache.refreshKey(meta.lastModified);
+```
+
+## API Reference
+
+- `HeadInput` — `{ options, url, signal, ctx }`.
+- `performExists(input): Promise<boolean>`.
+- `performGetMetadata(input): Promise<StatResult>`.
+
+## Implementation Notes
+
+`StatResult` is imported from `@suaveplan/storage-uri` (the canonical
+shape consumed by the resolver) so the metadata returned by the bundle
+shim is plug-compatible with every other URI plugin's response. The
+`last-modified` parser uses `new Date(rawHeader)` and discards values
+where `getTime()` returns `NaN`; that is the same gate every other
+HTTP-stat parser uses. `content-length` is parsed via
+`parseInt(_, 10)` rather than `Number(_)` so leading/trailing whitespace
+is tolerated but exponents and decimals are rejected.

+class deliberately implements the immutable-bundles contract — `set`,
+`setPartial`, `delete`, `clear`, and `list` all reject synchronously with
+`BUNDLE_URI.READ_ONLY` carrying the offending operation name on the `op`
+discriminant for dashboard correlation.
+
+The shim is split across four files in the same feature directory to keep
+each under the 300-line ceiling: this file is the class itself,
+`storage-shim.fetch.ts` provides `safeFetch` / `assertSuccess`,
+`storage-shim.head.ts` provides the HEAD-backed `exists` /
+`getMetadata`, and `storage-shim.range.ts` provides the Range pipeline.
+
+## Features
+
+- `get` / `exists` / `getMetadata` / `getPartial` / `createReadStream`
+  on top of `FetchLike`.
+- AbortSignal pre-check + mid-flight rewrap via the abort helpers.
+- Optional in-memory LRU front (off unless `options.cache` supplied).
+- HTTP `Range` header with 206/200/416 disambiguation; `data:`/`blob:`
+  roots always slow-pathed.
+- Streaming via `Response.body` direct forwarding with one-chunk
+  fallback when `body` is null.
+- Read-only enforcement on every write surface — `READ_ONLY` carries
+  `op` for filter-friendly diagnostics.
+
+## Usage: Basic
+
+```ts
+import { BundleStorageShim } from "@suaveplan/storage-uri-plugin-bundle";
+
+const shim = new BundleStorageShim({
+    packageSlug: "my-pkg",
+    rootUrl: new URL("https://cdn.example/my-pkg/"),
+    fetch: globalThis.fetch.bind(globalThis),
+    clock: () => performance.now(),
+});
+const bytes = await shim.get("assets/x.wav");
+```
+
+## Usage: Advanced
+
+```ts
+import { BundleStorageShim } from "@suaveplan/storage-uri-plugin-bundle";
+
+const shim = new BundleStorageShim({
+    packageSlug: "my-pkg",
+    rootUrl: new URL("file:///pkgs/my-pkg/"),
+    fetch: globalThis.fetch.bind(globalThis),
+    clock: () => Date.now(),
+    cache: { maxBytes: 1_000_000 },
+});
+const partial = await shim.getPartial("assets/big.bin", 0, 1024);
+```
+
+## API Reference
+
+- `new BundleStorageShim(resolvedOptions)` — construct.
+- `get(key, signal?): Promise<Uint8Array | undefined>`.
+- `exists(key, signal?): Promise<boolean>`.
+- `getMetadata(key, signal?): Promise<StatResult | undefined>`.
+- `getPartial(key, offset, length, signal?): Promise<Uint8Array>`.
+- `createReadStream(key, signal?): Promise<ReadableStream<Uint8Array>>`.
+- `set` / `setPartial` / `delete` / `clear` / `list` — all reject with
+  `BUNDLE_URI.READ_ONLY`.
+- Public `rootKind` field exposes the resolved root-kind classification
+  for diagnostics.
+
+## Implementation Notes
+
+`urlOf(key)` returns `rootUrl` directly for `data:`/`blob:` roots since
+those schemes are single-resource and `new URL(rel, root)` is either
+undefined-behaviour or throws. `ctxFor` builds the per-operation context
+once (`uri`, `packageSlug`, `relPath`, `rootKind`) so every helper that
+needs the diagnostic fields receives the same shape. `outcomeOf` is a
+small private classifier that maps the thrown `BundleUriError` code to
+the OTel `outcome` label (`not_found` / `aborted` / `error`).

+# Range read pipeline
+
+## Purpose
+
+`storage-shim.range.ts` carries the full `getPartial` pipeline: pre-fetch
+offset/length validation, the `Range: bytes=…` header build, the 206 /
+200 / 416 status-code disambiguation, and the
+`data:` / `blob:` single-resource fast-fallback path. Extracting the
+pipeline keeps the main shim under the 300-line ceiling and lets the
+range pipeline be unit-tested in isolation.
+
+The pipeline is fetch-agnostic only in the sense that the dispatch
+goes through the injected `FetchLike`; everything else
+(slicing, counter increments, error-code resolution) is shared with the
+canonical helpers in `range/range.ts`.
+
+## Features
+
+- Pre-fetch `validateRange` so caller-side mistakes never hit the wire.
+- HTTP `Range` header with 206/200/416 disambiguation.
+- `data:` / `blob:` roots short-circuited to a full-body fetch +
+  client-side slice + counter increment (single-resource model per
+  `design.md §2`).
+- 416 → `RANGE_INVALID` carrying `httpStatus: 416`, `offset`, `length`.
+- 200 fallback path increments `bundle_uri.range_fallback_total`.
+
+## Usage: Basic
+
+```ts
+import { performRangeRead } from "@suaveplan/storage-uri-plugin-bundle";
+
+const bytes = await performRangeRead({
+    options,
+    url,
+    key: "assets/x.bin",
+    offset: 0,
+    length: 1024,
+    signal: undefined,
+    ctx,
+    rootKind: "http",
+});
+```
+
+## Usage: Advanced
+
+```ts
+const bytes = await performRangeRead({
+    options,
+    url: new URL("data:application/octet-stream;base64,AAAA"),
+    key: "ignored",
+    offset: 0,
+    length: 2,
+    signal: undefined,
+    ctx,
+    rootKind: "data",
+});
+// Range header dropped; full body fetched and sliced; fallback counter ++.
+```
+
+## API Reference
+
+- `RangeReadInput` — `{ options, url, key, offset, length, signal,
+  ctx, rootKind }`.
+- `performRangeRead(input): Promise<Uint8Array>`.
+
+## Implementation Notes
+
+The 416 branch drains the response body via
+`res.arrayBuffer().catch(() => undefined)` so the underlying connection
+is released — some HTTP servers stall the next request on the same
+keep-alive connection if the prior body is left hanging. The `200` and
+`206` branches share the same `arrayBuffer + sliceForRange` path; the
+slicer's `{ bytes, fallback }` tuple is what surfaces the counter-
+increment decision. The `data:` / `blob:` short-circuit fetches with
+`new URL(rel, root)` ignored because both schemes are single-resource.

+# toReadableStream
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+
+## Purpose
+
+`streaming.ts` exposes the single helper the storage shim consumes from
+its `createReadStream` implementation: given a fetch `Response`, return a
+`ReadableStream<Uint8Array>` that the caller can pipe, transform, or
+consume. The helper is the smallest possible surface that still covers
+both the happy path (modern `fetch` returns a non-null `body`) and the
+fallback path some polyfills exhibit where `body` is null and the caller
+must buffer through `arrayBuffer()`.
+
+The fallback intentionally produces a one-chunk stream rather than
+streaming bytes through a TransformStream — once the body has been fully
+buffered there is no benefit to chunking, and a single `enqueue` keeps
+the downstream consumer's `read()` loop trivially terminating.
+
+## Features
+
+- Direct forwarding of `Response.body` when present — zero copy, zero
+  buffering.
+- One-chunk fallback wrapping the buffered `arrayBuffer()` bytes when
+  `body` is null.
+- Always returns a `ReadableStream<Uint8Array>` (matches the
+  `StreamingStorageExtensions.createReadStream` contract in
+  `@suaveplan/storage-uri`).
+
+## Usage: Basic
+
+```ts
+import { toReadableStream } from "@suaveplan/storage-uri-plugin-bundle";
+
+const res = await fetch(url);
+const stream = await toReadableStream(res);
+```
+
+## Usage: Advanced
+
+```ts
+import { toReadableStream } from "@suaveplan/storage-uri-plugin-bundle";
+
+const res = await fetchImpl(url, { signal });
+const stream = await toReadableStream(res);
+for await (const chunk of stream as unknown as AsyncIterable<Uint8Array>) {
+    consume(chunk);
+}
+```
+
+## API Reference
+
+- `toReadableStream(response): Promise<ReadableStream<Uint8Array>>` —
+  forwards `response.body` when non-null, otherwise wraps
+  `arrayBuffer()` in a one-chunk stream.
+
+## Implementation Notes
+
+The fallback explicitly constructs the `Uint8Array` from the
+`ArrayBuffer` returned by `arrayBuffer()`. Using `arrayBuffer()` then
+re-wrapping is intentional — some polyfills return a `Response` whose
+`body` is null but whose `arrayBuffer()` resolves to the full payload,
+and the shim needs to honour the streaming contract regardless. The
+returned stream is owned by the caller — once it is consumed (or
+cancelled), the underlying response is released.

+# BundleUriPluginOptionsSchema
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+
+## Purpose
+
+`plugin-options.schemas.ts` declares the Zod schema that validates
+`BundleUriPluginOptions` at construction time. The schema enforces the
+`packageSlug` regex from `design.md §1`, accepts `rootUrl` as either a
+string or `URL` instance, and rejects unknown keys via `.strict()` so
+caller typos surface rather than silently being ignored.
+
+The schema is consumed by `factory.ts`, which converts Zod validation
+failures into `BundleUriError(BUNDLE_URI.INVALID_URI)` carrying the
+underlying `ZodError` on `cause` — preserving every issue for diagnostic
+serialisation without polluting the public error API with Zod types.
+
+## Features
+
+- Slug regex `^@?[a-z0-9][a-z0-9._/-]{0,127}$` matching the npm-package
+  name subset declared in the ABNF grammar.
+- `rootUrl` accepts both `string` (URL-validated via `z.string().url()`)
+  and `URL` instance (via `z.instanceof(URL)`).
+- `.strict()` rejects unknown keys so option-bag typos are loud.
+- Optional `cache.maxBytes` is a positive integer; the LRU layer rejects
+  non-positive values up-front.
+
+## Usage: Basic
+
+```ts
+import { BundleUriPluginOptionsSchema } from "@suaveplan/storage-uri-plugin-bundle";
+
+const parsed = BundleUriPluginOptionsSchema.parse({
+    packageSlug: "my-pkg",
+    rootUrl: "https://cdn.example/my-pkg/",
+});
+```
+
+## Usage: Advanced
+
+```ts
+import { BundleUriPluginOptionsSchema } from "@suaveplan/storage-uri-plugin-bundle";
+
+const result = BundleUriPluginOptionsSchema.safeParse({
+    packageSlug: "Bad Slug",
+    rootUrl: new URL("file:///x/"),
+});
+if (!result.success) {
+    console.error(result.error.issues);
+}
+```
+
+## API Reference
+
+- `BundleUriPluginOptionsSchema` — Zod object schema with `.strict()`.
+- `BundleUriPluginOptionsInput` — `z.input<typeof schema>`.
+
+## Implementation Notes
+
+The schema does NOT normalise `rootUrl` to a `URL` instance — that
+happens in `factory.ts` once a value is in hand — because Zod transforms
+make the output type harder to consume from the surrounding TypeScript.
+`z.custom` is used for `fetch` and `clock` rather than a typed function
+schema because Zod's `z.function()` produces a wrapper that is not byte-
+for-byte compatible with `FetchLike`/`Clock` under
+`exactOptionalPropertyTypes`. The default `import z from "zod"` form is
+mandated by the project memory for Bun-safe parsing.

+# BundleUriPluginOptions
+
+## Purpose
+
+`plugin-options.types.ts` declares the public option bag accepted by
+`bundleUriPlugin(...)` and the internal `ResolvedBundleUriPluginOptions`
+shape produced after Zod validation has normalised every input.
+
+The split exists because callers pass a permissive surface — `rootUrl` may
+be a string or `URL`, `fetch`/`logger`/`clock` are all optional — while
+the rest of the package consumes the post-validation shape where `rootUrl`
+is always a `URL`, `fetch` always defined, and `clock` always present.
+
+## Features
+
+- Required `packageSlug` and `rootUrl`, optional dependencies.
+- Structural typing — no runtime classes — keeps the types-only file
+  importable from anywhere without pulling runtime code.
+- `ResolvedBundleUriPluginOptions` matches the contract of `factory.ts`
+  so the rest of the codebase consumes a single canonical shape.
+
+## Usage: Basic
+
+```ts
+import type { BundleUriPluginOptions } from "@suaveplan/storage-uri-plugin-bundle";
+
+const opts: BundleUriPluginOptions = {
+    packageSlug: "audio-ir-room-plugin-club",
+    rootUrl: new URL("./", import.meta.url),
+};
+```
+
+## Usage: Advanced
+
+```ts
+import type {
+    BundleUriPluginOptions,
+    ResolvedBundleUriPluginOptions,
+} from "@suaveplan/storage-uri-plugin-bundle";
+
+declare function bundleUriPlugin(o: BundleUriPluginOptions): {
+    readonly resolved: ResolvedBundleUriPluginOptions;
+};
+
+const out = bundleUriPlugin({
+    packageSlug: "@suaveplan/font-subset",
+    rootUrl: "https://cdn.example/font/",
+    cache: { maxBytes: 1_000_000 },
+    fetch: globalThis.fetch.bind(globalThis),
+});
+```
+
+## API Reference
+
+- `BundleUriPluginOptions` — public surface (everything but `packageSlug`
+  and `rootUrl` is optional).
+- `ResolvedBundleUriPluginOptions` — post-validation shape consumed by the
+  rest of the package.
+
+## Implementation Notes
+
+`FetchLike`, `LoggerLike`, and `Clock` are imported from `@suaveplan/types`
+rather than redeclared so the plugin transparently composes with every
+other  package that consumes the same canonical contracts.
+The file deliberately carries no runtime exports — it is excluded from
+coverage by the default `*.types.ts` rule in `createTestConfig`. The
+public shape uses `readonly` modifiers throughout because every
+downstream consumer treats the option bag as a value object, never
+mutating it; rebinding via spread is the supported pattern when an
+override is needed at runtime. The resolved shape preserves the
+`logger` and `cache` optional-keys so `exactOptionalPropertyTypes`
+consumers can detect "intentionally absent" versus "explicitly
+undefined" without ambiguity.
