The publish-body condensation removed exact operator-facing statements pinned by the prerelease packet test. Restore those statements within the three-highlight limit, record the packet contract, and strengthen the proof to require the complete publish-safe sentences.
The internal/api race suite now routinely exceeds the old 20-minute package timeout on hosted runners while passing. Set a governed 30-minute package timeout and 40-minute release job ceiling, pin the relationship with contract tests, and refresh the rc.4 packet with the fixes landed since preparation.
The installer staged the download in /tmp and installed the runtime
binary to /usr/local/bin, both on the small RAM-backed QTS/QuTS hero
root, and the boot wrapper copied 34MiB back onto that root at every
boot. Roots without ~50MiB of headroom could not install at all, and
setting TMPDIR only moved the staging half of the requirement.
QNAP's own QPKG packages execute from the data volume, so do the same:
relocate the install dir to the data volume's state dir before the
preflight and download, default TMPDIR there too, skip the boot-time
self-copy when the stored and runtime binaries are one file, and remove
a pre-relocation runtime copy from /usr/local/bin to give that space
back. Split layouts with an operator-supplied state dir keep the copy
semantics. The rendered wrapper is exercised in both layouts by the
installer tests.

Contract-Neutral: Refs #1617: QNAP installer layout fix with its deployment-installability contract clause staged in this commit; residual proof policies for unrelated boundaries do not apply to this shell-only change
Live proof on a real systemd host (Debian 12 container, full
install/report/update/uninstall cycle) caught what no unit test did:
NoNewPrivileges=true blocks sudo outright, so the --grant-smart and
--grant-pct helpers failed inside the service and SMART/pct silently
disappeared while the install reported success. A unit with an active
grant now sets NoNewPrivileges=false, keeping the rest of the hardening;
a grantless least-privilege install keeps NNP enabled. Docs and contracts
state the trade-off: each grant is a scoped, auditable widening.
Also proven in the same live cycle: the flag-conflict refusals, user and
sudoers provisioning, wrapper execution as the service user, the healthy
privilege report ({runningAsRoot:false, serviceUser:pulse-agent,
smartctlHelper:true}), --update preserving the profile without repeated
flags, and uninstall removing the sudoers file and helpers.
The unified agent's Linux installer only offered the root profile, and the
docs called non-root unsupported. That default is the most-cited reason
security-conscious evaluators reject Pulse without trying it. install.sh
gains --least-privilege: the service runs as a dedicated nologin
pulse-agent system user with every existing hardening directive, no
LXC-attach ambient capabilities, docker-group membership for socket reads,
and refusal (not silent root fallback) on appliance platforms, non-systemd
init systems, and --enable-commands. Optional --grant-smart and --grant-pct
restore the only two collectors that need elevation through
visudo-validated exact-command sudoers rules and root-owned wrappers the
agent reaches via new absolute-path-only PULSE_SMARTCTL_PATH /
PULSE_PCT_PATH overrides; the pct grant covers pct list and pct df only
and can never widen into pct exec. --update preserves the profile and its
grants by reading the installed unit.
The agent now authors a privilege block in its report (effective root,
service user, active helpers), carried through models into the fleet
doctor as a descriptive field: Agent Doctor shows the profile and its
helpers instead of presenting intentionally absent collectors as a fault,
and a least-privilege agent can never be marked unhealthy on that evidence
alone.
The dormant self-hosted business tier opens for public checkout under the
dials the owner approved on 2026-08-20: \$399/year annual-only, unlimited
seats, 365-day history, next-business-day support target, Pro-identical
features per cloud-paid Extension Point 26. Newly issued Pro
subscriptions carry a 3-seat max_users limit on new Stripe price ids;
previously issued licenses keep their unlimited posture because their
plan entries are untouched. The 2026-08-08 opt-in presentation posture is
unchanged: Business appears only through the public pricing-model payload
and checkout, and no proactive in-product surface returns.
Adds the decision record, resolves the decision in status.json, lifts the
EP26 dormancy sentence, and extends the subsystem_lookup decision-id pin.
License-server and landing changes land separately in pulse-pro.
lxc-attach into an unprivileged guest writes /proc/<pid>/uid_map, which
needs CAP_SETUID in the parent user namespace. NoNewPrivileges drops
CAP_SETUID from the effective set and also stops lxc-attach falling back
to the setuid newuidmap/newgidmap helpers, so the socket probe dies with
"write_id_mapping: 61 Operation not permitted".
install.sh already relaxed NoNewPrivileges for this, but only when the
agent was installed with --enable-commands. Command execution is also
togglable from the server afterwards: applyRemoteConfig starts the
command client without rewriting the unit. An agent installed without
the flag and switched on later therefore ends up able to run commands
and unable to attach to unprivileged guests, so Docker inside every
unprivileged LXC disappears from the Proxmox page. The probe failure is
logged at debug level and retried on every poll, so the surface looks
empty rather than broken while the agent re-probes the whole guest list.
Grant CAP_SETUID/CAP_SETGID to any PVE agent rather than gating on the
install-time flag, so the later toggle lands on a unit that can attach.
Ambient capabilities restore exactly the privilege lxc-attach needs and
leave the rest of the sandbox intact; the existing install-time
relaxation is unchanged.
Verified on a live PVE node. With the hardened unit the probe succeeded
only on the three privileged guests and failed on every unprivileged
one. After the ambient grant CapEff regained CAP_SETUID and both
unprivileged Docker guests were discovered, taking that node from one
Docker LXC to three.
Contract-Neutral: Routine release-preparation cut for v6.3.0-rc.3. deployment-installability.md IS staged with the substantive active-prerelease and mobile-decision updates for this cut. The residual demand is a verification artifact, and the registry-listed proof scripts/installtests/build_release_assets_test.go plus install_docker_sh_test.go already cover this change and pass against it; they validate the packet dynamically from the repo-root VERSION rather than pinning a literal, so they have no diff to stage. Both were run green immediately before this commit and caught two real errors in the mobile-decision clauses, which are fixed here.
