fix(helm): default sandbox Services to ClusterIP (#3929) (#4190)
* fix(helm): default sandbox Services to ClusterIP (#3929)

The K8s sandbox provisioner supports both NodePort and ClusterIP via
SANDBOX_SERVICE_TYPE (added in #4016), but the Helm chart never set it,
so real-cluster installs inherited the NodePort default. That bound the
code-execution sandbox on every node's interfaces - including externally
reachable ones on GKE/EKS/AKS - and pinned every sandbox URL to one node
IP (SPOF on node reboot/drain/ephemeral-IP).

Default the chart to ClusterIP: the provisioner returns a cluster-DNS URL
(http://sandbox-<id>-svc.<ns>.svc.cluster.local:8080) so the gateway->
sandbox hop stays inside the cluster network - no node IP, no 30xxx port,
no external exposure. The chart always runs the gateway in-cluster, so
ClusterIP is always correct there.

NodePort remains an opt-in (provisioner.sandboxServiceType: NodePort +
nodeHost) for the Docker-Compose/hybrid path where the gateway is not in
K8s and cannot resolve .svc.cluster.local; the provisioner code default
stays NodePort for that path.

- values.yaml: add provisioner.sandboxServiceType ("ClusterIP")
- provisioner-deployment.yaml: emit SANDBOX_SERVICE_TYPE; gate the
  NODE_HOST block on NodePort mode (default "ClusterIP" for upgrade safety)
- NOTES.txt + README.md: document ClusterIP default + NodePort opt-in

No change to docker/provisioner/app.py (already mode-aware since #4016)
or RBAC (services verbs already cover ClusterIP).

* test(helm): assert sandbox Service-type gating + CHANGELOG the default flip (#3929)

Address review on #4190:

- Add scripts/check_chart_sandbox_service.sh: renders the chart for the
  default (ClusterIP, no NODE_HOST), the NodePort opt-in (both emitted),
  and NodePort+nodeHost (literal value, not downward API). Locks in the
  #3929 gating so a regression (e.g. re-adding an unconditional NODE_HOST,
  or dropping the `default "ClusterIP"` upgrade-safety fallback) fails CI.
  Wired into .github/workflows/chart.yaml validate-chart job. (#2)
- CHANGELOG [Unreleased] -> Changed: note the NodePort->ClusterIP default
  flip on upgrade + the `sandboxServiceType: NodePort` opt-back-in. (#4)

No chart template changes (the gating itself landed in the first commit).

fix(memory): flush memory queue on graceful shutdown to prevent loss (#4181)
* fix(memory): bounded shutdown flush via MemoryManager.shutdown_flush

Re-applies the memory-queue shutdown drain on top of the pluggable
MemoryManager abstraction (#4122): the old top-level MemoryUpdateQueue
singleton is gone, so the drain is now a backend contract instead of
host code reaching into the queue.

- MemoryManager ABC: shutdown_flush(timeout) -> bool. Every backend
  implements a bounded graceful-shutdown drain.
- DeerMem: queue.flush_sync (daemon-thread + Event.wait hard timeout
  for the uninterruptible sync LLM call; joins an in-flight worker
  first so contexts a debounce Timer already pulled out are not lost on
  exit; skips inter-item sleep on the drain path; per-item
  succeeded/failed count), exposed via shutdown_flush.
- noop: shutdown_flush is a clean no-op success.
- Gateway lifespan: call get_memory_manager().shutdown_flush(timeout)
  after channels/scheduler stop, via asyncio.to_thread, try/except
  bounded. No host-level pending/processing guard -- the backend
  short-circuits on an idle buffer, so the host cannot "forget" the
  in-flight case (structurally eliminates the guard race flagged on the
  prior revision).
- shutdown_flush_timeout_seconds added to the shared MemoryConfig
  (host-owned lifecycle budget, default 30, 1-300) + exposed on
  MemoryConfigResponse and the embedded client; config_version 25 -> 26.

Tests: queue flush_sync (7), lifespan drain incl. False-branch caplog
assertion + disabled gate (3), ABC contract noop/deermem (3).

* fix(chart): gateway grace period so memory drain is not SIGKILLed

K8s defaults terminationGracePeriodSeconds to 30s, shorter than the
Gateway's graceful-shutdown work (channel stop ~5s + memory queue drain
default 30s). Without an explicit grace period, K8s SIGKILLs the memory
drain mid-flight and silently re-introduces the loss shutdown_flush is
fixing (flagged on the prior revision).

- gateway pod: terminationGracePeriodSeconds (default 45, configurable).
- gateway container: preStop sleep (default 5, 0 disables) so the
  Service/ingress deregisters the pod before SIGTERM begins the drain.
- values.yaml + README: both configurable; README documents that the
  grace period must track memory.shutdown_flush_timeout_seconds.

* docs(memory): document shutdown_flush_timeout_seconds + lifespan drain

Add the host-shared field to the memory config list and Config Schema
summary in backend/AGENTS.md, noting the lifespan drain and the K8s
grace-period relationship.

* fix(chart): bump embedded config_version to 26

The chart's embedded `config:` block (values.yaml + README example) still
had config_version: 25 after commit f3ca8e9f raised config.example.yaml to
26, failing the validate-chart config_version drift check. Bump both to 26.

feat(authz): add pluggable AuthorizationProvider protocol and config scaffolding (Phase 0, #4063) (#4127)
Phase 0 of the RFC in #4063: scaffolding only, zero behavior change.

New deerflow/authz/ package (sibling to deerflow/guardrails/):
- AuthorizationProvider Protocol: authorize() + aauthorize() + filter_resources()
- Principal/AuthzRequest/AuthzDecision/AuthzReason dataclasses
- GuardrailAuthorizationAdapter: bridges AuthorizationProvider → GuardrailProvider
  so existing GuardrailMiddleware can enforce authz decisions without a new middleware

New authorization config section (default enabled: false):
- AuthorizationConfig wired into AppConfig alongside guardrails
- Singleton load/reset mirrors GuardrailsConfig pattern
- config.example.yaml documents the RBAC provider schema

29 tests covering protocol conformance, dataclass construction, adapter
request/decision mapping, and config singleton behavior.

Per RFC #4063 Phase 0 (foundations). Layer 1/2 wiring and Principal builder
in services.py deferred to Phase 1.

ci(helm): publish chart to charts/ namespace prefix on GHCR (#4175)
* ci(helm): publish chart to charts/ namespace prefix on GHCR

Push the Helm chart to ghcr.io/<owner>/charts/deer-flow (via a `charts/`
prefix on the `helm push` target) instead of the bare `deer-flow`
package. This namespaces the chart apart from the image packages
(deer-flow-{backend,frontend,provisioner}) without renaming the chart:
Chart.yaml `name` stays `deer-flow`, so dir = chart name = in-cluster
resource/selector names, and no `nameOverride` hack is needed.

The chart is new in 2.1.0 (chart infra landed in #3987, after v2.0.0),
so 2.1.0 is the first chart release. Early nightly builds remain at the
legacy non-prefixed ghcr.io/<owner>/deer-flow.

Also refresh chart release docs:
- Replace the removed scripts/build-and-push.sh in the chart README with
  raw `docker build`/`push` commands (contexts/args match container.yaml).
- Point NOTES.txt's empty-registry warning at the README section instead
  of the removed script.
- Retarget RELEASING.md version examples from 2.2.0 to 2.1.0.
- Bump the chart README's helm prerequisite to 3+.

* docs(helm): require helm 3.8+ and note legacy chart package cleanup

Address PR #4175 review:
- bump documented minimum to helm 3.8 (OCI registry support stabilized
  there; earlier 3.x needs HELM_EXPERIMENTAL_OCI=1)
- add a post-release note to delete/revoke the legacy bare
  ghcr.io/<owner>/deer-flow chart package after 2.1.0

perf(boxlite): add benchmark-driven warm-pool reclaim tuning (#4001)
* bench: add provider-agnostic sandbox benchmark with BoxLite warm pool results

- scripts/bench_sandbox_provider.py: CLI for measuring acquire/run/release
  across providers, scenarios, workloads, and concurrency levels
- scripts/summarize_bench.py: JSONL aggregation with p50/p95/p99 tables
- bench_results.jsonl: 110 turns across 7 scenarios on real BoxLite 0.9.7

Key findings:
  cold acquire:  ~860ms
  warm reclaim:   ~14ms  (60x speedup)
  release:         ~0ms
  warm_hit_rate:  95%   (warm_same_thread)

* perf(boxlite): skip health check for recently-released warm pool boxes

Boxes released within health_check_skip_seconds (default 5.0s)
are promoted directly without the ~14ms echo-ok round-trip.
A VM alive seconds ago is overwhelmingly likely to still be alive.

Add sandbox.health_check_skip_seconds config option.
Set to 0 to always health-check (old behaviour).

Benchmark (warm_same_thread, noop, 20 iters):
  acquire p50: 14.9ms → 0.0ms
  total p50:   29.9ms → 14.0ms

* chore: move benchmark scripts into backend/scripts/benchmark/

* fix: address BoxLite benchmark review findings

* fix(boxlite): only skip warm reclaim checks for released boxes

* fix(benchmark): keep BoxLite shim workaround off the event loop

* fix(boxlite): invalidate dead boxes from command path

* test(boxlite): cover skip window and invalidation edge cases

* fix(boxlite): treat sandbox-has-been-closed as terminal in _exec

* fix(boxlite): harden warm-pool reclaim and benchmark accounting

* fix(boxlite): validate warm-pool reclaims by default

* fix(config): expose boxlite health-check skip setting

* fix(boxlite): tighten failure classification and benchmark workaround

* Update config_version to 21 in values.yaml

feat(deploy): first-class Helm chart for Kubernetes deployment (#3987)
* feat(helm): add production-ready Helm chart for Kubernetes deployment

Adds deploy/helm/deer-flow, a native-Kubernetes translation of the
production docker-compose stack, plus CI to publish its images and chart.

* ci(release): gate releases on version-source consistency

Add a reusable verify-versions workflow invoked by both chart.yaml and
container.yaml on v* tags. It runs scripts/verify_versions.sh against the
tag and fails the release — skipping all image and chart publishing — when
Chart.yaml (version + appVersion), backend/pyproject.toml, or
frontend/package.json don't all match the tag.

Add scripts/verify_versions.sh (the check, also runnable locally) and
scripts/bump_version.sh (bumps all four sources in lockstep, then
self-verifies). Document the release flow in RELEASING.md and link it from
AGENTS.md.

* fix(deploy): address Helm chart review feedback (#3987)

Three review items from willem-bd:

1. nginx IPv6 listen strip never matched. The sed pattern required a `;`
   immediately after `2026`, but the rendered config emits
   `listen [::]:2026 default_server;` (space + `default_server` before the
   `;`), so the line was never deleted and nginx crash-looped on pods
   without IPv6 (`socket() :::2026 failed (97: Address family not
   supported)`). Drop the trailing `;` from the pattern so it matches.
   Same latent bug fixed in docker-compose-dev.yaml.

2. Passwords were spliced into DSNs verbatim, so a password containing
   URL-special chars (@ : / # ? % [ ] space) produced a malformed DSN and
   a confusing parse error. Add a `deer-flow.urlEscape` helper
   (replace-based: Sprig lacks urlqueryescape, and regexReplaceAllLiteral
   treats the replacement as a regex template so `[`/`]`/`?` break it) and
   apply it to the password in the postgres and redis DSNs. The raw
   `postgres-password` / `redis-password` keys stay unencoded - they back
   POSTGRES_PASSWORD / REDIS_PASSWORD, not a URL segment.

3. NODE_HOST defaulted to "gateway", which can never route: the gateway
   Service is ClusterIP:8001 and knows nothing of a sandbox NodePort, so a
   user who skips the caveat gets unreachable sandboxes with no error at
   install time. Default NODE_HOST to the provisioner pod's node IP via
   the downward API (status.hostIP) - a NodePort is exposed on every node,
   so <node-IP>:<NodePort> routes from the gateway on most clusters.
   `provisioner.nodeHost` remains an override for CNIs/policies that block
   pod->node-IP traffic. Updated NOTES.txt, values.yaml, and the chart
   README. (#3929 remains the long-term fix - ClusterIP + cluster-DNS URL
   removes NODE_HOST and the NodePort exposure entirely.)

Validated with helm lint, helm template (incl. a special-char password
rendering the encoded DSNs), and a sed pattern-match check.

* fix(deploy): address round-2 Helm chart review feedback (#3987)

Three "Medium" items from willem-bd:

1. No helm lint / helm template gate before publish. A template regression
   ships as an immutable OCI artifact (GHCR won't overwrite --version), so
   gate packaging on `helm lint` + `helm template --include-crds` in
   chart.yaml before `helm package`. (ct lint / helm-unittest deferred.)

2. Action pinning inconsistent + PR body overstates it. SHA-pin
   actions/checkout (v6.0.3, df4cb1c0) and actions/attest-build-provenance
   (v2.4.0, e8998f94) across the publishing workflows (chart.yaml,
   container.yaml, verify-versions.yml), matching the existing docker/*
   SHA-pin pattern. Resolves the checkout @v4/@v6 mismatch and makes the
   "SHA-pinned actions" claim accurate. Other pre-existing workflows left
   untouched (out of scope for this PR).

3. Provisioner RBAC broader than needed. Dropped the unused update/patch
   verbs and the pods/exec + events rules from the provisioner Role -
   audited against docker/provisioner/app.py, which only calls
   get/create/delete on pods and get/list/create/delete on services. Fixed
   NOTES.txt to accurately describe the grant instead of understating it as
   "create Pods and Services". The remaining scope concern - verbs apply to
   all Pods in the namespace, not just sandbox Pods - is still deferred
   (RBAC can't scope by label; needs a dedicated namespace or admission
   control), now noted in NOTES.txt and README.

Validated with helm lint + helm template (narrowed Role renders with
exactly get/list/watch/create/delete).

* feat(helm): enable sandbox+web tools out of the box

The chart's default config loaded zero agent tools (config.tools empty ->
"Total tools loaded: 0"), so a fresh install gave an agent that could do
nothing useful. Add tool_groups + tools to the default config block:

- web: web_search (ddg), web_fetch (jina), image_search - no API key
- file:read: ls, read_file, glob, grep
- file:write: write_file, str_replace
- bash

The file/bash tools run inside the AIO sandbox the chart already
configures; the web tools need outbound internet from the gateway pod
(swap backends or drop entries for air-gapped clusters - see
config.example.yaml).

Also bump config_version 15 -> 19 to match config.example.yaml (the chart
had drifted behind). NOTES.txt and the README example updated to match.

* ci(helm): add chart validation + config_version drift check on PR

Extend the chart workflow with a PR-triggered validate-chart job that runs
helm lint, helm template --include-crds, and a config_version drift check:
it parses config_version from both config.example.yaml and the chart's
values.yaml and fails the build (with a ::error:: naming the files to bump)
if the chart is behind the example. This catches the kind of drift this
PR is fixing - the chart sat at v15 while the example moved to v19 - before
it can merge again.

verify-versions and publish-chart stay tag-only; publish-chart now
needs: [verify-versions, validate-chart]. validate-chart runs on both
PRs and tag pushes: the tag arm is required because a job that `needs`
a skipped job is itself skipped under the default success() check, so
validate-chart must actually run on tag pushes or publish-chart would
never fire.

* Bump config version to 20
