+/**
+ * outbox-log — read-only diagnostic inspection of `@ng-org/web`'s offline write
+ * outbox, at session bootstrap (polyfill-era, low-level-data-path trace).
+ *
+ * ── What this surfaces ──────────────────────────────────────────────────────
+ * `@ng-org/web` (the real injected SDK) queues writes made while offline/
+ * disconnected in an "outbox", persisted client-side in `sessionStorage` by the
+ * WASM verifier (see `sdk/rust/src/local_broker.rs` `JsStorageConfig::
+ * get_js_storage_config` in the `nextgraph-rs` core repo — read-only reference,
+ * NOT vendored here). A non-empty outbox at session start is an ANOMALY worth
+ * surfacing unconditionally: it means writes from a previous (disconnected)
+ * session are still queued and haven't reached the broker yet.
+ *
+ * ── sessionStorage key shapes (verified in the core repo, not guessed) ──────
+ * The outbox is keyed per LOCAL PEER id (`peer_id`, the persistent local peer's
+ * pubkey — NOT the ng-eventually shim's `account`/`identity` concept), via two
+ * key families written by `session_write`/read by `session_read`:
+ *   - `ng_peer_last_seq@<peerId>`         — the peer's last reserved seq number.
+ *   - `ng_outboxes@<peerId>@start`        — the seq number the outbox starts at.
+ *   - `ng_outboxes@<peerId>@<00000-idx>`  — one queued (base64url + BARE-encoded)
+ *     event per zero-padded index, contiguous from 0 until the first miss (the
+ *     exact shape `outbox_read_function` walks — see `local_broker.rs`).
+ * We don't know `peerId` ahead of time (it's internal to the injected SDK), so
+ * we DISCOVER it by scanning `sessionStorage` for `@start` markers instead of
+ * requiring it to be passed in — this also means the probe works unchanged
+ * however many peers/wallets the browser session has touched.
+ *
+ * ── Read-only, defensive, best-effort ────────────────────────────────────────
+ * This NEVER writes or deletes a key (unlike the real `outbox_read_function`,
+ * which drains on read) — it only counts. The queued event bytes are opaque
+ * (BARE-encoded Rust structs, base64url'd); decoding them to report concrete
+ * write TARGETS (topics/docs) would mean duplicating the WASM verifier's wire
+ * format in this polyfill, which is explicitly out of scope (SDK internals live
+ * in the `@ng-eventually/client`-independent core repo, per this repo's
+ * doctrine) — so only the pending COUNT is reported, never fabricated targets.
+ * `sessionStorage` access itself can throw (sandboxed iframe, disabled storage —
+ * see the exact error string handled in the core repo's `main.ts`
+ * `convert_error`), so the whole probe is wrapped in one try/catch: unavailable
+ * → skip silently, never throw into the caller.
+ *
+ * Polyfill-era; removed at the real multi-store migration alongside the rest of
