…643) A gate paused on AGENTFLARE_DISPATCH_GATE_MODE=off baked into the daemon's environment had no way to clear short of env-var archaeology, and `agentflare daemon restart` didn't help since restart just re-reads the same stuck env var on every startup. Add agentflare_resource_gate::force_resume()/clear_force_resume(): a sticky override that turns a stuck GateMode::Off into GateMode::Auto on every sampler tick until cleared, applied immediately rather than waiting for the next 30s sample. Genuine CPU pressure (PauseReason::CpuPressure) is untouched by the override, since that's the exact protection the gate exists for. Expose it via GET/POST /api/gate and /api/gate/reset on the dashboard (the gate's state lives in that process, split into its own dashboard/gate.rs module to stay under the LOC gate), and `agentflare daemon gate status`/`agentflare daemon gate reset` in the CLI to reach it over HTTP.

- Line 91: Serialize policy sampling and updates in the sampler and force_resume
by acquiring the STATE write lock before sampling. In force_resume, set
FORCE_RESUME and write the resumed policy while holding that lock, preserving
the flag update when STATE is unavailable.
- Around line 95-105: Update clear_force_resume() to refresh the initialized
STATE immediately after clearing FORCE_RESUME, using the current GateConfig and
sample_policy result so current_policy() reflects the inactive override without
waiting for the next sampler tick.
In `@src/dashboard/gate.rs`:
- Line 22: Add authorization to the `/api/gate/reset` route registered in the
router, or ensure this endpoint remains loopback-only when `--yes-expose`
enables non-local binds. Do not leave `gate_reset_handler` able to call
`force_resume()` for unauthenticated remote clients.

Protect /api/gate/reset when --yes-expose is enabled.
The default bind is loopback-only, but --yes-expose permits non-local binds without authentication. The merged router has no authorization check, and gate_reset_handler directly calls force_resume(). Any client that can reach the listener can therefore clear the off gate. Require an authorized caller for this endpoint, or keep it loopback-only.

…force_resume CodeRabbit review on PR #805 flagged two races: the periodic sampler computed its decision outside the STATE write lock, so it could clobber a force_resume()'d state with a stale Paused(UserDisabled) decision for up to 30s; and clear_force_resume() only cleared the flag without refreshing STATE, so current_policy() kept returning the resumed policy until the next sampler tick. Both now sample while holding the write lock.

…olicy() reads (#806) Serializing writers by holding STATE's RwLock write guard across sample_policy() (per CodeRabbit's suggested fix on PR #805) fixed the stale-overwrite race but introduced a new problem: sample_policy() sleeps ~250ms inside Signals::sample()'s CPU probe, and holding the write guard across that sleep blocks current_policy()'s .read() on the hot dispatch path it's supposed to be a cheap read from. Add a separate WRITER_LOCK mutex to serialize the sampler thread against force_resume()/clear_force_resume() (fixing the original race) while keeping STATE's write guard held only for the final assignment, so readers never block on the slow sample. Also dedupe force_resume/clear_force_resume into a shared set_force_resume() helper.

Committed clean. Final summary:
What I did: Fixed the "5th gap" from #635/#636/#638 — the resource dispatch gate had no reset/unpause path when stuck on
AGENTFLARE_DISPATCH_GATE_MODE=off, anddaemon restartdidn't clear it since restart just re-reads the same stuck env var.crates/agentflare-resource-gate/src/gate.rs: addedforce_resume()/clear_force_resume()/force_resume_active(). A sticky atomic override makes the sampler treat a stuckGateMode::OffasGateMode::Autoon every tick until cleared, applied immediately rather than waiting up to 30s. It never overrides genuinePauseReason::CpuPressure— that's self-clearing and is exactly what the gate protects against.src/dashboard/gate.rs(new module):GET /api/gate(status) /POST /api/gate/reset, since the gate's state lives in the daemon process, not the CLI's. Split into its own module (matching the existingchat.rspattern) to stay under the repo's 1500-line LOC gate onserver.rs.src/dashboard/data.rs:gate_status_json()helper, following the existingclaims_json/cost_jsonconvention.src/cli/daemon.rs: newagentflare daemon gate status/agentflare daemon gate resetsubcommands that hit the dashboard over HTTP (default127.0.0.1:35273, matchingagentflare serve's default).Tests/verification (all run synchronously, foreground):
cargo test -p agentflare-resource-gate— 28/28 pass, including a new single consolidated test for the force-resume override (deliberately one test, not three, sinceFORCE_RESUMEis a shared static and parallel test threads would race on it).cargo check -p agentflare --all-targets— clean (only pre-existing unrelatedunsafe-lint warnings elsewhere).cargo clippy --locked -p agentflare --all-targets --all-features -- -D warnings -A unsafe_code -A clippy::pedantic— clean.cargo fmt --all --check— clean.LOC gatepre-commit hook passed.Concerns: I didn't add a
config.tomlreset path (epic #331 isn't live yet, matches existing convention of env-var-only config here). Didn't wire an autostart/systemd re-exec offorce_resumeon daemon crash-restart — since the override lives in-process, a full daemon process restart still requires callingdaemon gate resetagain if the env var is still set; that's expected given the daemon completely re-execs.
