Keep gloved in a systemd-owned supervisor leaf while creating sibling session cgroups under the empty delegated parent. Under mapped-root supervisors, attach blocked children before releasing their existing start gate instead of combining nested UID mapping with CLONE_INTO_CGROUP.
Permit Node/libuv read-only type inspection only on committed child
descriptors while offline socket and connect remain denied.
Recheck queued input after audit and around response release. Late
pipelined frames now poison the channel instead of crossing the gate.
MEDIUM 1: session_runtime::start() now returns an explicit
fresh-launch vs replay disposition (session_start_result), and
handle_start_session sets outcome.applied only for a fresh committed
launch. An authenticated idempotent start replay therefore never gains
connection-scoped teardown authority: a broken pipe during a replay can
no longer stop an already-running guest. The control audit event for a
replayed delivery carries the replay disposition
(start_session:replay:<session>).
MEDIUM 2: jsonl_sink truncation now accounts for record delimiters
exactly, so current_bytes_ always tracks the physical file; only
newline-terminated complete records are retained (no blank or partial
lines, bounded read window); the cap is a hard cap (an oversized event
is dropped with a structured operator note; a pre-existing oversized
journal is bounded with a bounded read at construction).
MEDIUM 3: the broken-pipe degrade test now synchronizes through a
mutex-protected condition-variable gate handshake that proves the
dispatch is parked inside the blocked gate before the client resets,
records the start only after the dispatch completes, and the
mark_stopping test destroys every registry lock holder (runtime,
protocol, registry) before the independent registry reopen so the
nonblocking exclusive flock can actually be acquired.
Introduce the framed guest_channel_transport with shared deadlines and
std::jthread ownership, metadata-only retired-schema quarantine with
fail-closed integrity, stateless frozen-catalog validators with
capability pinned to zero, and the generic local-service proxy with
descriptor-pinned endpoints, alias-only guest sockets, audit-gated
delivery, and a Linux managed runtime capability derived only from a
registry-bound operational factory. Sage vocabulary is confined to
src/adapters/sage.
Combine maintainer/wallet-status-and-apple-repairs (18e75af8) with
maintainer/guest-channel-layer (00d7c473) into a single validated
integration branch for Ghost deployment testing.
Merge resolution decisions:
- Apple container runtime (the known conflict zone) auto-merged
textually and was verified semantically against both parents:
the maintainer hard-disable survives (lifecycle_operational()
returns false unconditionally, apple_container_session_runtime.hpp),
the sampler/finalizer jthread lifecycle seam and the finalizer
catch-all well-formed terminal state (a96ab1e) are intact, and
null_terminated=false strict_json_options is preserved. Velinus's
observation-intent integration lands adapted on the repaired base:
prepare_observation_service is only reachable from start(), which
denies before side effects when the lifecycle is disabled, so the
observation service never constructs on the disabled Apple path.
The gated test from PR #25 (every control method refuses before
side effect; record counts unchanged) survives.
- GLOVE_GUEST_OBSERVATION_* env names kept; observation socket/token
volumes still mount only when observation_service->active().
- guest_channel layer, host-registered schema admission
(channel_descriptor/channel_host), SO_PEERCRED/LOCAL_PEERCRED, LRU
replay cache, bounded retry, fail-closed recovery, and
channel_identifier_grammar.hpp land as-is; session_registry files
did not conflict with PR #24's side.
- Wallet status files: PR #25's delta did not touch them, so the
harness-neutral renames (wallet_status_projection_channel) stand
unchanged.
Validation (umask 0022): dev/asan/tsan presets build clean and
CTest 80/80 each (control_apple_container_session_runtime
env-gated/skipped as expected); clang-format (llvm@22) applied to
changed sources; git diff --check clean. No push.
Generalizes the PR #23 guest observation plumbing into a schema-agnostic
specialized-channel layer while keeping all harness policy out of core.
Generalized admission (F2/HIGH):
- New channel_descriptor/channel_host interface (include/glove/control/
guest_channel.hpp): hosts register {channel_id, schema_id,
body_validator, bounds{max_items, max_body_bytes, max_ttl_ms,
max_skew_ms}, on_exchange} at registry construction; core keeps only
structural invariants (identifier charset, digest hex, TTL/skew
arithmetic, capacity, idempotency) and delegates body semantics to
registered validators.
- The closed two-schema check in session_registry internals is removed:
glove_observation_schema, glove_sxxx_proposal_* constants and the
fixed SXXX digest move out of session_registry_impl.hpp. The Sage
schemas are now registered by the harness adapter
(apple_detail::sage_guest_channel_host) and gloved_main wires the host
into the registry; schema strings appear only in harness-adapter and
test-fixture registration examples.
- enqueue_observation_intent binds intents to the session's PARSED
runtime_id; the hardcoded sage_guest_runtime equality checks are
removed from session_registry.cpp, session_registry_recovery.cpp and
valid_record_shape. Replay of a now-unregistered schema fails closed
(open_or_create rejects stores carrying unadmitted intents), and
enqueue without an admission table is rejected. The observation
socket server takes runtime_id from configuration instead of
hardcoding "sage-guest". The observation body hash domain becomes the
harness-neutral "glove.observation-body.v1" (pre-merge delta; no
on-disk compatibility is preserved).
Recovery fix (F1/HIGH):
- same_session_snapshot now neutralizes state, running_at_ms and
policy_revision before comparing frozen intent/disposition snapshots
against the bound session record, so lifecycle progression and policy
revision advances never read as a binding crossing; every other
frozen-field difference still does. Exposed for tests. Regression
tests cover running->stopping and stopping->exited transitions plus a
late post-exit disposition end to end (destroy/reopen), and a
snapshot-identity unit test pins the neutralization (and proves
non-neutralized fields still cross). Note: an empirical probe showed
the previously-claimed failure does not reproduce under ordered
journal replay because intent/disposition records freeze the session
record they were appended from; the neutralization is applied as the
defensive fix the memo requires and is now pinned by tests.
Hardening:
- F3: peer-uid verification (SO_PEERCRED / LOCAL_PEERCRED) on observation
socket accepts, configurable expected uid, rejecting unexpected peers
before any frame is read.
- F4: the replay cache is a bounded LRU (configurable capacity), so the
old fixed 1024 cap can no longer permanently kill the channel; the
durable registry remains the authoritative idempotency layer.
- F5: transient wait/accept errors (EINTR/EAGAIN/ECONNABORTED/EMFILE/
ENFILE/ENOBUFS/ENOMEM) are retried inside serve_one_for with a bounded
backoff ladder; only persistent or fatal errors surface. The Apple
worker loop absorbs persistent failures up to a consecutive-failure
bound and emits an audit event (new audit action "observation") on
repeated failures instead of dying on the first hiccup.
- F6: env/mount names generalized to GLOVE_GUEST_OBSERVATION_SOCKET /
GLOVE_GUEST_OBSERVATION_TOKEN_FILE and the in-container token path to
/home/agent/.glove-observation-token (Apple runtime, docs).
Apple boundary: the soft lifecycle_operational() definition is unchanged;
the lifecycle-disabled lane now additionally asserts start_session/
stop_session deny with method_not_found and leave the registry untouched
(denial before side effects; the observation service only constructs
inside a lifecycle-gated start).
Docs: architecture.md and session-policy.md describe the guest
specialized-channel admission model and the peer-uid/env naming.
Validation (umask 0022):
- cmake --preset dev/asan/tsan + build + ctest: 100% (76/76) in each
configuration; asan/tsan are warnings-as-errors builds.
- git diff --check clean; changed files clang-formatted with Homebrew
llvm@22 against the repo .clang-format.
- No fuzz target exists for the queue/registry (fuzz/ covers plans,
bundles, manifests, MCP codec, jsonpath only), so no fuzz corpus run.
- control_remote_validation_executor is a pre-existing load-sensitive
sleep-race test; it flakes identically on the unmodified pr23-head
baseline under CPU load (verified 1/6 both trees) and always passes
isolated.

Merge PR #23 head 4097a21adb (Velinus's
"Make Apple resource sampling lifecycle safe") into the Layer-2
integration branch, preserving all contributor commits unchanged.
Retained proven fixes from 4097a21:
- Sampler creation moves into start_finalizer() so a sampler
std::system_error is reported synchronously to the caller. In
ca8600a the sampler was constructed inside finalize() after the
caller had treated startup as successful; the failure path
published an error without attach reaping, container deletion, or
durable mark_managed_failed, and set finished_ so stop() became a
no-op while attach/container survived.
Repairs retained beyond the contributor head, each bound to a
demonstrated failure:
- std::jthread + deterministic stop_token handles the partial-start
case where sampler construction succeeds but finalizer launch
fails (regression: tests/control/apple_container_unavailable_test
and the start_sampler_then_finalizer seam used by production).
- Restored hard-disabled Apple boundary: lifecycle_operational()
false, receipt schema 0, disk enforcement unavailable, empty
managed runtime advertisement, and public method denial before
any side effect. The current PR #23 head crossed the reviewed
activation boundary (schema 0 -> 1, filesystem_quota advertised,
lifecycle constructed-state true) without live-validation.
- glaze parsing hardened: strict_json_options now sets
null_terminated=false; non-NUL-terminated string_views fed
parse_apple_container_stats and duplicate_key_guard caused a
heap-buffer-overflow read in glz::skip_ws (ASan crash input
[{"id":"aanumProcesses" reproduced deterministically; seed corpus
fuzz/corpus/apple_container_stats/truncated-object.json added).
- Sage bundle projection admission hardening (Layer-1 2bba117) and
its test coverage carried through the merge.
Validation (umask 0022):
- Dev CTest 76/76; ASan/UBSan 76/76; TSan 76/76.
