 - `**baretop**`: optional `**ctx.bareOsReadBareTopSnapshot()**` in `[index.js](index.js)` returns `**{ atMs, files, metricsLiveText }**` (`**metricsLiveText**` = coalesced `**metrics_live**` JSON string) with the same `**files**` keys as `**BARE_TOP_SNAPSHOT_PROC_ENTRIES**` in `**packages/bare-os-coreutils/lib/baretop-snapshot.js**` — keep those lists in sync when adding operator `**/proc/bare_os**` nodes.
 - **hrpc allowlist**: shared parser in `[lib/bare-os-hrpc-allowlist.js](lib/bare-os-hrpc-allowlist.js)`; `**ctx.bareOsHrpcRequest**` and `**ctx.bareOsHrpcAllowlistProbe**` stay aligned. Host passthrough copies `**BARE_OS_HRPC_ALLOWLIST_JSON**`, `**BARE_OS_CORESTORE_SNAPSHOT_WORKFLOW_JSON**`, `**BARE_OS_BLIND_RELAY_TOPOLOGY_JSON**`, `**BARE_OS_MIRROR_DRIVE_COMPOSITION_HINT_JSON**`, `**BARE_OS_REPLICATION_PLAN_JSON**`, and pear-doctor env keys into session env.
 - **Snapshot hints**: `**ctx.bareOsReadSnapshotHintsJson()**` merges `**BARE_OS_CORESTORE_SNAPSHOT_WORKFLOW_JSON**` like `**/proc/bare_os/snapshot_hints.json**`.
- **Pipeline / IPC / rlimits tuning** — Simulated pipeline capture honors **`BARE_OS_PIPELINE_ABS_MAX_BYTES`** / **`BARE_OS_PIPELINE_ABS_MAX_LINES`** (defaults **512 MiB** / **2 000 000** lines after the streaming multiplier). When the host leaves pipeline keys unset, the stock booter seeds **`BARE_OS_SHELL_STREAMING=1`**, **`BARE_OS_SHELL_STREAMING_MULT=2`**, **`BARE_OS_PIPELINE_MAX_BYTES`** (**512 MiB**), **`BARE_OS_PIPELINE_MAX_LINES`** (**2 000 000**). Host passthrough includes **`BARE_OS_IPC_MAX_CHANNELS`**, POSIX MQ defaults (**`BARE_OS_POSIX_MQ_MAX_MSGS`**, **`BARE_OS_POSIX_MQ_MSG_BYTES`**), **`BARE_OS_VFS_MAX_OPEN`** → **`/proc/bare_os/rlimits.json`** **`RLIMIT_NOFILE`**, and convenience aliases **`BARE_OS_STREAMING_MULTIPLIER`**, **`BARE_OS_TIMER_BUDGET_MS`**, **`BARE_OS_TELEMETRY_OTEL`**.
