* feat(sandbox): add gpu sandbox scheduling support
Allow sandbox creation to request GPU resources explicitly or infer them from GPU image names. This wires GPU intent through bootstrap, validates gateway support, and adds dedicated GPU E2E coverage for follow-up cluster testing.
* docs(examples): add sandbox policy quickstart walkthrough
Add an interactive getting-started example that demonstrates OpenShell's
network policy system end-to-end: default-deny, L7 read-only access,
and audit logging — all with a single YAML policy file.
- examples/sandbox-policy-quickstart/policy.yaml: policy with default
static fields (filesystem, landlock, process) so it works out of the
box with `openshell policy set`
- examples/sandbox-policy-quickstart/demo.sh: automated demo script
using printf (portable) and openshell ssh-proxy for sandbox exec
- examples/sandbox-policy-quickstart/README.md: step-by-step manual
walkthrough
- README.md: add "See network policy in action" section linking to the
quickstart

* docs: soften default-deny wording to minimal outbound access
Sandbox defaults vary by type and community configs, so
"all outbound traffic is blocked" is too absolute.
Made-with: Cursor
* docs: use curl -sS so L4 deny errors are visible
curl -s suppresses stderr, hiding the 403 from the CONNECT
proxy. Adding -S ensures the error message is always shown.

* feat(tui): add log copy and visual selection mode
Add clipboard support for the TUI log viewer using OSC 52 escape
sequences. Users can copy individual log lines (y), the visible
viewport (Y), or enter visual selection mode (v) to select a range
of lines with j/k and yank with y.
- Add clipboard module with OSC 52 base64 encoding
- Add format_log_line_plain() for plain-text log rendering
- Add visual selection mode with highlight styling and status bar
- Context-switch nav bar hints between normal and visual modes
- Add 7 unit tests for plain-text log formatting
Closes#274
* fix(tui): write OSC 52 to /dev/tty instead of stdout
ratatui owns stdout via the alternate screen buffer, so OSC 52
escape sequences written to stdout are swallowed by the backend.
Write directly to /dev/tty to bypass the buffer and reach the
terminal emulator.
* feat(tui): support light terminal backgrounds with adaptive theme
Replace the hardcoded dark-only color constants in theme.rs with a
runtime Theme struct that has dark() and light() factory constructors.
The active theme is stored on App and threaded through all draw
functions, enabling the TUI to render correctly on both dark and light
terminal backgrounds.
- Add Theme struct with 16 semantic style fields and ThemeMode enum
- Detect terminal background via COLORFGBG env var at startup
- Add --theme dark|light|auto CLI flag and OPENSHELL_THEME env var
- Migrate all 499 styles:: references across 11 UI files to app.theme
- Clean up 9 inline Style constructions that bypassed the theme system
- Add unit tests verifying dark/light palettes and legacy regression
Closes#264
* fix(tui): use OSC 11 query for reliable light/dark terminal detection
Replace COLORFGBG env var heuristic with terminal-colorsaurus crate,
which sends an OSC 11 query to read the actual background color. This
fixes auto-detection in iTerm2 and other terminals that don't set
COLORFGBG.
* fix(proxy): stream inference responses instead of buffering entire body
The inference.local proxy path called response.bytes().await which
buffered the entire upstream response before sending anything to the
client. For streaming SSE responses this inflated TTFB from sub-second
to the full generation time, causing clients with TTFB timeouts to abort.
Add a streaming proxy variant that returns response headers immediately
and forwards body chunks incrementally using HTTP chunked transfer
encoding. Non-streaming responses and mock routes continue to work
through the existing buffered path.
Closes#260
* docs: update architecture docs and example for inference streaming
* test(example): add direct NVIDIA endpoint tests via L7 TLS intercept
Expand inference example to 4 test cases: inference.local and direct
endpoint, each streaming and non-streaming. The direct path exercises
the L7 REST relay (relay_chunked) to verify it already streams
correctly. NVIDIA_API_KEY is picked up from the sandbox env when
started with --provider nvidia.
* edit tutorial per nv style guide
* few more edits
* iron out a bit more
* rephrase prereqs
* iron out policy update section
* improve update policy section
* nit
* rebase and improve
* merge the new policy update steps finalized with Kirit
* Kirit's change requests
* feat(policy): add policy recommendation plumbing — denial aggregation, transport, approval pipeline, and mechanistic recommendations
Implement the infrastructure layer for automated policy recommendations (#204):
- Proto: 9 new RPCs and messages for draft policy lifecycle (submit, get, approve, reject, approve-all, edit, undo, clear, history)
- Persistence: SQLite/Postgres migrations and store methods for draft_policy_chunks and denial_summaries tables
- Server: Full gRPC handler implementations with mechanistic mapper that auto-generates NetworkPolicyRule proposals from denial summaries
- Sandbox: DenialAggregator with MPSC channel, deduplication, periodic flush to gateway via SubmitPolicyAnalysis
- CLI: 'openshell draft' subcommand with get/approve/reject/approve-all/undo/clear/history operations
- TUI: Draft recommendations panel accessible from sandbox policy view
- Docs: Architecture documentation in architecture/policy-advisor.md
* feat(policy): add L7-aware mechanistic mapper and policy advisor CTF example
Add L7 rule generation to mechanistic mapper (build_l7_rules,
generalise_path, looks_like_id) with 3 new unit tests. Add
examples/policy-advisor/ with a 7-gate CTF script, restrictive
sandbox policy, and walkthrough README.
* fix(policy): use sandbox name for denial flush and add TUI draft badges
Fix denial aggregator passing sandbox UUID instead of name to
SubmitPolicyAnalysis, which caused 'sandbox not found' errors on
flush. Add notification badges to the TUI sandbox list and detail
header showing pending draft recommendation counts.
* fix(policy): deduplicate draft chunks and tolerate overlapping OPA rules
Skip draft chunk creation when a pending/approved chunk already covers
the same host:port endpoint, preventing duplicate rules across denial
aggregator flush cycles.
Rewrite three OPA complete rules (network_policy_for_request,
matched_network_policy, matched_endpoint_config) to tolerate multiple
matching policies without triggering a "complete rule conflict" error.
network_policy_for_request becomes a boolean, matched_network_policy
uses a set comprehension with min(), and matched_endpoint_config uses
an array comprehension with index-0 selection.
* feat(tui): interactive draft actions, highlight bar, and detail popup
Rework the draft recommendations panel to match the logs UX:
- Highlight bar (green accent + background) instead of arrow marker
- Viewport-aware j/k scrolling with g/G for top/bottom
- Enter opens a full-screen detail popup showing endpoints, binaries,
rationale, security notes, and action hints
Add approve/reject/approve-all draft actions:
- [a] approve selected chunk, [x] reject, [A] approve all pending
- Actions work from both the list view and the detail popup
- gRPC calls run async; result updates status bar and refreshes data
- Nav bar shows all available keybindings
Fix draft count refresh: sandbox_draft_counts now refreshes on every
tick (not just Dashboard), so the detail header badge updates in
real time.
Improve badge labels: show 'N pending' instead of a bare number in
both the dashboard sandbox list and sandbox detail header.
* refactor(policy): DB-level draft chunk dedup with hit counter and timestamps
Replace the in-memory HashSet dedup in SubmitPolicyAnalysis with a
database-level upsert. New denormalized columns on draft_policy_chunks:
- host, port: extracted from proposed_rule at insert time
- hit_count: incremented on conflict (same sandbox + host + port)
- first_seen_ms, last_seen_ms: track when the endpoint was first and
most recently proposed
A partial unique index (WHERE status IN ('pending','approved')) ensures
only one active chunk per endpoint per sandbox; rejected/superseded
chunks don't block new proposals.
Surface hit_count and first/last_seen in:
- CLI: 'openshell draft get' shows 'Hits: N (first ..., last ...)'
- TUI: detail popup shows hits row; list view shows 'Nx' suffix
* fix(policy): optimistic retry on policy version conflicts + structured logging
merge_chunk_into_policy and remove_chunk_from_policy now retry up to 5
times on UNIQUE constraint violations (version conflicts from concurrent
approvals). Each attempt re-reads the latest policy, re-merges the rule,
and increments the version. This eliminates the race condition where
rapid successive approvals would fail with a DB error.
Add structured tracing to all draft action handlers:
- ApproveDraftChunk: logs rule_name, host, port, hit_count before merge
and version + policy_hash after success
- RejectDraftChunk: logs rule_name, host, port, reason
- ApproveAllDraftChunks: logs pending_count at start, per-chunk merge
progress, and final summary with chunks_approved/skipped
- UndoDraftChunk: logs before/after with rule_name and version
- Retry attempts log as warnings with attempt number and conflicting
version
* wip: forward proxy fix, mapper allowed_ips, TUI polish, CTF rewrite
* fix(tui): use correct --gateway flag for ssh-proxy ProxyCommand
* chore: add Docker cleanup script for stale images, volumes, and build cache
* feat(tui): approve-all confirmation modal and CTF cleanup
Add [A] confirmation popup that snapshots pending chunks, shows a
scrollable list, and approves each chunk individually on confirm.
This prevents approving chunks that arrived after the modal opened.
Remove transient issue #205 reference from CTF victory banner.
* fix(tui): correct import ordering for rustfmt
* wip: stateful toggle model, rename to network rules
Draft chunks now follow a toggle state machine:
pending -> approved | rejected (initial decision)
approved <-> rejected (toggle)
One row per (sandbox_id, host, port) via expanded unique index.
Rejecting an approved rule removes it from the active policy.
Re-approving a rejected rule merges it back.
Rename CLI from 'draft' to 'rule', TUI from 'Draft Recommendations'
to 'Network Rules'. State-aware keybindings: approved shows [x] Revoke,
rejected shows [a] Approve. Fix sandbox detail hiding delete confirmation
behind pending message.
* refactor(policy): move mapper sandbox-side, slim schema, per-binary granularity
Move mechanistic mapper from gateway to sandbox so all analysis runs
sandbox-side (N sandboxes = N independent pipelines). Gateway is now a
thin validate + persist + approval layer.
Architectural changes:
- Move mechanistic_mapper.rs from navigator-server to navigator-sandbox
- Sandbox flush flow: aggregator drains -> mapper runs -> proposals sent
- Gateway SubmitPolicyAnalysis: validate + persist only, no mapper
- Drop denial_summaries table (write-only, zero readers)
- Consolidate migrations 003+004+005 into single 003
Schema slimming:
- Drop 5 unused columns from draft_policy_chunks (stage, denial_refs,
supersedes_chunk_id, analysis_mode, decided_by)
- Add per-binary granularity: binary column, widen unique index to
(sandbox_id, host, port, binary)
- Mapper groups by (host, port, binary), one proposal per triple
- Merge appends binary to existing rule; revoke removes just that binary
CTF & UX:
- 7-gate CTF: add Gate 3 (curl -> ifconfig.me:80) for per-binary demo
- TUI shows binary short name in list, full path in detail popup
- CLI output shows binary field
- Idempotent rule names, hit_count accumulates real denial counts
- Rationale text no longer bakes in stale denial count
Add OPENSHELL_SANDBOX_IMAGE_PULL_POLICY env/CLI flag that propagates
through Config -> SandboxClient -> pod spec generation. When set, the
policy is applied to both inline and pod-template sandbox containers.
Helm chart exposes server.sandboxImagePullPolicy (default empty = K8s
default behavior). cluster-deploy-fast sets it to Always so dev
clusters always pull fresh sandbox images.
cluster-deploy-fast.sh ran helm and kubectl directly on the host,
which requires a local kubeconfig pointing at the k3s API server.
Since the cluster container does not expose port 6443, these commands
always fail with 'connection refused'.
Install helm in the cluster container image and run all helm/kubectl
commands via docker exec with KUBECONFIG pre-configured. The local
chart directory is copied into the container before helm upgrade.
The k9s COPY instruction was added without a corresponding build stage,
causing Docker to look for a nonexistent docker.io/library/k9s image.
Add a multi-arch stage that downloads the k9s binary from GitHub releases.
* fix(cli): improve completion coverage and gateway selection
Closes#232
Add typed completion metadata for gateway, sandbox, and path arguments, make gateway selection interactive on TTYs, and expose root subcommands in completions while keeping non-interactive behavior stable.
Add --gpu flag to 'openshell gateway start' that enables NVIDIA GPU
access inside the cluster container. When enabled, the Docker container
receives GPU device requests via bollard, k3s auto-detects the NVIDIA
runtime, and the NVIDIA k8s-device-plugin is deployed via HelmChart CR
so Kubernetes workloads can request nvidia.com/gpu resources.
- Add GPU device request to Docker container creation (bollard DeviceRequest)
- Set GPU_ENABLED=true env var to gate GPU manifest deployment
- Multi-stage Dockerfile build to bundle NVIDIA Container Toolkit binaries
- Conditional GPU manifest copy in cluster entrypoint
- HelmChart CR for nvidia-device-plugin v0.18.2 with GFD and NFD enabled
- Thread gpu bool through DeployOptions, CLI flag, and run dispatch

* refactor(docker): rename server image to gateway
Rename Dockerfile.server to Dockerfile.gateway and update all image
references from openshell/server to openshell/gateway across Helm
charts, Kubernetes manifests, mise tasks, build/deploy scripts, CI
workflows, and documentation.
The underlying Rust binary (navigator-server) is unchanged -- this
rename only affects the Docker image name and Dockerfile.
* fix: catch remaining server->gateway references in docs and comments
* feat(sbom): add SBOM generation, license resolution, and CSV export tooling
Add mise-integrated SBOM pipeline for container images using Syft.
Includes license resolution via crates.io/npm/PyPI APIs and CycloneDX
JSON to CSV conversion. Adds agent skill for on-demand SBOM operations.
Closes#237
* fix(sbom): chain task dependencies to run generate → resolve → csv sequentially
* fix(sbom): add concurrent license resolution, progress logging, and exclude dev artifacts
* feat(notices): add mise run notices to generate THIRD-PARTY-NOTICES with full license texts
Use cargo-about for Rust crate licenses and pip-licenses for Python
packages. Produces a single attribution file with per-package copyright
notices and full license text for open-source compliance.
Migrate all production container runtime stages from Debian/Ubuntu
upstream to NVIDIA's hardened Ubuntu base image for supply chain
consistency.
- Dockerfile.ci: ubuntu:24.04 -> nvidia base
- Dockerfile.server: debian:bookworm-slim -> nvidia base (runtime stage)
- Dockerfile.base (sandbox): python:3.12-slim-bookworm -> nvidia base
with system Python 3.12 from Ubuntu Noble repos
- Dockerfile.cluster: convert from single-stage rancher/k3s to
multistage build extracting k3s artifacts onto nvidia base
Closes#244
Replace the clear_process_identity + maybe_infer_sandbox_user workaround
with strict enforcement: run_as_user and run_as_group must always be
'sandbox'. If omitted from YAML, they are defaulted server-side via
ensure_sandbox_process_identity(). Any other value is rejected.
This fixes 'policy set' failing with 'process policy cannot be changed
on a live sandbox' for custom-image sandboxes, where the CLI was
clearing identity fields but the YAML had 'sandbox' explicitly set.
- Remove clear_process_identity() from CLI and TUI
- Add ensure_sandbox_process_identity() to default missing fields
- Rename RootProcessIdentity -> InvalidProcessIdentity
- Replace maybe_infer_sandbox_user with validate_sandbox_user (fail-fast)
- Update OPA test policies to use run_as_user: sandbox
