Answer the GLAS-WP-0015 handoff for SAND-WP-0015-T04 without activating any
production path.
Add candidate profile profile.claude-agent-dev-proof v1.1.0 (ext.bwrap,
localhost-only, default: deny, declared api.anthropic.com:443) for GLAS-WP-0012
review. The committed profile grants no egress by itself — ext.bwrap refuses it
unless owner extension config independently allowlists the destination — and a
regression test asserts that fail-closed default.
Reconcile the differing project examples in favour of the acceptance runner's
actor agt / project glas-local-proof, keeping the documented credential route
bound to that single project rather than broadening it.
Record the return contract (profile revision, host scope, consumer tuple,
runtime digest and mount paths, declared egress, value-free denial/cleanup
receipts) in docs/bwrap-runtime.md.
T04 stays wait: Claude credential lane, owner machine authentication, pinned
Claude executable and real-model acceptance remain operator gated.

Reachability gains pid/workspace_dir, populated by enrich_reachability
whenever a backend's wait_ready() returns a pid: endpoint (currently
just ext.bwrap). build_reachability_report() now also returns a
local_exec_hint (nsenter into the pid's namespaces) alongside the
existing ssh_one_liner, so glas-harness can branch on which is
populated instead of assuming every sandbox is SSH-reachable.

Adds the first local, same-host, kernel-namespace-only sandbox
extension: no SSH hop, no container runtime. Extends IsolationSpec.level
with "process", implements BwrapExtension (provision/wait_ready/
teardown) spawning bwrap with unshared user/mount/pid/ipc/uts/net
namespaces, registers ext.bwrap + profile.bwrap-local, and extends
manager._handle_from_status to carry pid/workspace_dir. Verified with a
live bwrap smoke run in addition to the mocked test suite.
T04 (reachability vs. the SSH-based glas-harness consumer contract)
deliberately left open pending glas-harness's harness contract.

First local, same-host, kernel-namespace-only sandbox extension --
every current self-hosted extension requires an SSH hop plus a
container runtime or VM. Also the first extension able to actually
enforce the network.default: deny every profile already declares.

Add workspace checkpoint API with SnapshotStore, extension hooks on
compose-ssh and saas-stub, manager orchestration, CLI/HTTP surface,
profile.compose-checkpoint, and docs/tests.
Refresh SCOPE.md for v0 operational state after WP-0002/0003/0008.
Add history/ INTENT↔SCOPE assessment and ready workplan for the-custodian
e2e shim to close the e2e-framework migration arc.
Rewrite INTENT.md as the sand-boxer meta-framework charter (OpenRouter-style
sandbox API, extensions, payments, Coulomb sibling boundaries). Add research
under research/, update SCOPE.md, bootstrap workplans SAND-WP-0001/0002, and
State Hub integration files from the bootstrap pass.
