From d3dc3ce85b72869497a8f0a32815609e48a26c62 Mon Sep 17 00:00:00 2001 From: pallakatos Date: Tue, 8 Sep 2026 20:28:50 +0200 Subject: [PATCH 01/96] feat(github): add bounded keyless service integration candidate Preserve optional standalone behavior and isolate GitHub App credentials by exact identity, installation and repository. Include governed Actions logs and reviewed gzip/permission repairs. Local Rust/runtime qualification and bounded automated closure are complete; operator materialization, SRE privacy-gate integration and full acceptance remain explicit blockers. This is a local checkpoint, not public readiness or deployment.

This service does +not implement independent review, branch ownership, workflow scheduling, or +automated publication/merge policy. + +## Egress, bounds, errors, and logs + +- Existing signed egress policy and threat blocklist remain mandatory for both + GitHub API authentication and data-plane hosts. No implicit allowlist grant is + introduced. Git/API destinations are fixed to `github.com`/`api.github.com`. +- Actions logs accept one GitHub 302 to HTTPS port 443 under + `.blob.core.windows.net` or `.actions.githubusercontent.com`, without userinfo + or fragments. The exact destination must also pass existing egress policy. + The download sends **no GitHub credential** and never follows another redirect. + Prefer exact operational storage-host egress approvals over entire suffixes. +- Two concurrent requests per router; 90-second total deadline; each upstream + operation has a 10-second connect and 45-second request timeout. No automatic + retries, including 401 or ambiguous accepted mutation failures. +- Git requests/responses: 16 MiB each. REST requests/responses: 2 MiB each. + Job logs: at most 32 MiB downloaded; last 2 MiB returned with + `X-Kars-Log-Truncated: true` when truncated. Oversized or interrupted upstream + responses fail explicitly, rather than fabricating successful partial logs. +- Git POST accepts an absent content encoding or one `Content-Encoding: gzip` + value (case-insensitive, emitted canonically as `gzip`). Compressed negotiation + bytes are forwarded unchanged with that validated coding; the 16 MiB request + cap applies to **wire bytes**, without decompression in the router. + Unsupported, comma-separated or repeated encodings return 415 before token + acquisition. Content encoding on other methods/API requests is unsupported. + No other client headers are implicitly forwarded. +- GitHub authentication error bodies, signed URLs, tokens and request bodies are + never logged by the service. Upstream non-success responses preserve actionable + HTTP status but suppress bodies and redirect/cookie headers. Responses are + `Cache-Control: no-store`; successful GitHub/log data is untrusted content. + The OpenClaw wrapper does not checkpoint CI log tool results into its activity + memory buffer. +- Tokens are cached per repository inside an immutable credential incarnation. + Concurrent misses share one mint; expiration is refreshed with a 60-second + margin. A 401 invalidates that exact cached token for a **future** request, + never replays the current request. + +## OpenClaw tool and downstream prerequisites + +`github_actions_job_logs(owner, repo, job_id, tail_lines?)` is independently +registered through the existing governed tool wrapper. It uses the loopback +keyless endpoint, validates path/job inputs, has a 95-second deadline and 2 MiB +response cap, and returns JSON with `repository`, `job_id`, `http_status`, +`tail_lines`, `truncated_before_tail`, and `log`. Defaults: 250 final lines; +maximum: 2,000. HTTP failures are explicit tool errors, not synthetic logs. + +Bridge/BFF or future runtime plans may depend on this exact contract, but must +first enroll the current Sandbox identity, configure the App/repositories, and +approve the required egress destinations.

Unsupported/repeated/comma-separated codings fail with 415 before + authentication. No general header forwarding, decoding, retry or limits + change was introduced. +2. Token profiles omitted `checks: read` and `statuses: read`, although the + bounded API permits check-run and combined-status reads. Both permissions are + now explicitly requested in read and write profiles and remain part of exact + returned-permission verification. Missing or broader returned permissions, + or an installation rejecting the required grants, fail closed without a + narrower retry or credential fallback. + +Six new Rust regressions cover actual gzip upload-pack negotiation bytes, +header/body/auth coherence, unsupported/multiple codings, compressed wire-byte +limits, exact read/write profiles, missing/overbroad permission attestations, and +installation-grant rejection without retry. They reuse existing `flate2`, +wiremock and RSA fixtures; no dependency changes were made. + +The parent subsequently ran all 33 selected Rust cases successfully (27 authored +GitHub cases and six existing provider cases), plus strict paired all-target +Clippy and formatting. Only two new test layouts required formatting. The same +independent automated reviewer found no significant issues in the bounded repair +delta. This does not constitute a human sign-off.

Empty/missing tenant credentials must +not start the gateway or block ordinary web-only operation. + +For legacy migration, inspect `status.legacySources`, review the source +namespace UID, Secret UID/resourceVersion, complete key-name set and target UID, +then supply that metadata array through `--legacy-review`. Existing values are +not printed or changed by preflight. Unsupported/reserved keys and ambiguous +ownership block import before projection; the operator must resolve them +explicitly. An unclaimed old runtime namespace still requires the independent +namespace-ownership workflow; credential migration does not adopt it. + +## Binding and delivery + +`credentialBindings` on a Task blueprint or directly authored Sandbox contains +the grant `{name, uid}` and ordered sources: + +1. explicitly selected workspace source; +2. explicitly UID-bound Team source; +3. explicitly UID-bound target source. + +Each selection contains a source `{name, uid}`, approved key names and, for +Team/target scopes, the owning target identity. References and key grants are +part of the shared effective Task authorization snapshot. Child references +and key sets may not exceed their parent's credential authority. + +Prelaunch sources remain unbound. Bridge stages Tasks/Teams without runnable +execution, captures the actual CREATE UID, attaches the source selections, and +only then requests activation. A CREATE conflict is never converted to adoption. +Core verifies current Task authority before preparing a UID-owned bundle and +the existing UID-fenced runtime projection. Agent values never enter router +EnvFrom. Runtime environment overrides of selected keys are rejected. + +Missing selected keys mask lower-priority values. Removing a key does not remove +the binding or restore direct credentials. Missing/replaced/revoked authority +stops the credential consumer and clears only its owned projection. Previously +governed consumers do not silently return to the old direct collection. + +`CredentialsReady` and grant status expose key names, source/bundle/projection +UIDs, observed versions and reasons—not values. Non-404 API errors are errors, +not an empty configuration. + +## Lifecycle and qualification + +Grant finalization revokes its owned writer/operator bindings. Namespace and +source UID checks prevent adopting a replacement. Source cleanup follows its +actual target UID; workspace sources and operator stores are not Helm-owned and +remain after Bridge uninstall. Legacy stores remain for explicit review. + +Kubernetes reconciliation is asynchronous. Permission, node or API failures +can delay consumer termination and revocation; this does not revoke a token at +its external provider or erase values an agent already observed. + +This candidate still requires coordinated Rust and real API/admission lifecycle +qualification before release.

Private Bridge adapts to the public core contract; it is not copied into +this repository. + +## Enforced boundaries + +- Operator-only grant authorship; no self-expansion by the Bridge ServiceAccount. +- Workspace/writer/source/target UID and source resourceVersion checks. +- No arbitrary source Secret reference, runtime namespace write by the + credential adapter, or fallback to legacy values on revocation. +- Default ten-key v1 compatibility; explicit custom agent key grants with + provider, identity and process-bootstrap exclusions. +- Full effective Task snapshot/digest includes credential references and key + grants; credential delegation checks parent attenuation. +- Core-owned namespace/projection writes and typed provider/Teams reconciliation. +- Namespace admission limits the private adapter's remaining namespace create + permission to its dedicated local-inference namespace. +- Enrolled-store UID/purpose admission, source-only Roles and no broad Secret + or Deployment mutation rule in either private Bridge RBAC manifest. +- No raw credential values in the grant schema, metadata status, preview files + or diagnostic messages. + +## Current validation + +Source formatting/parser checks and Helm lint have run without Cargo. Six +operator CLI preflight tests pass using the existing verified cache; CLI and +private web typechecks pass. Private add-on/packaging tests pass. No dependency +installation, Docker build, live cluster call, H100/cloud action or image push +was performed. + +Rust test and strict Clippy qualification require the separately coordinated +existing target lease. Real Kubernetes tests must demonstrate admission +type-checking, actual ServiceAccount permissions, first binding, source and +grant recreation, concurrent CAS, legacy migration, revocation, namespace +reuse, Team lifecycle and optional Teams bootstrap. Offline rendering and mocked +API tests alone cannot qualify those claims. + +Any author waiver on earlier publication PRs does not apply to this change. From b3f6ca83adcf65a2befcb5accab707874381b5a3 Mon Sep 17 00:00:00 2001 From: pallakatos Date: Tue, 8 Sep 2026 23:19:05 +0200 Subject: [PATCH 03/96] Checkpoint private credential issuers before GitHub integration Retain explicit unqualified lifecycle, UID and privacy blockers; this local checkpoint is not a publication or sign-off.

Preserve status lineage and pause UID-owned governed execution instead of deleting namespace/state. Keep optional observer availability independent of source readiness and prevent retired GitHub projections from returning through the legacy optional mount.

Replace Team credential unlaunch with owned pause/quiescence, current authority/receipt regeneration and fenced resume. Add focused API/full-reconcile regressions. Fast checks pass; core Rust qualification and bounded re-review remain required.

mutable path injection exists solely in test code, sharing the same bounded reader. No HTTP/configuration input can select another production file. Preserve credential rotation behavior and normal test fixtures. Extract the unchanged suspend/rebind replica decision into its owner module and cover all combinations, keeping the existing reconciler cap. Apply the full existing formatter instead of waiving CI. Affected tests, production binary checks, paired strict Clippy and the real cap/schema regression pass. No CodeQL alert is dismissed or query excluded.

From f8d641f660f6d2f43a0994f075b754fb4a1c4810 Mon Sep 17 00:00:00 2001 From: pallakatos Date: Wed, 9 Sep 2026 22:17:09 +0200 Subject: [PATCH 16/96] fix(credentials): align native UID admission and generated schemas Keep exact namespace UID checks using the actual Kubernetes JSON field despite the CEL NamespaceMetadata declaration mismatch. Add a native hosted positive/negative/positive probe using unchanged shipped predicates and owned fixtures, with precise denial assertions and bounded cleanup. Preserve bounded credential/GitHub schemas in generated Task/Team CRDs, compare rendered Helm includes, and add canonical grant CEL and standard labels. Local qualification: 30 Helm drift, 17 CNCF, 84 controller credential, 16 CLI contract and 53 Python harness cases; strict paired Clippy/fmt. Native API execution and complete hosted qualification remain pending. No audit signature or gate waiver.

bytes_stream dependency with Response::chunk, preserving bounded buffering and explicit transport/JSON failure. Full paired builds masked the missing reqwest stream feature in controller-only benchmark compilation (job102638710681 at f8d641f6). Add exact-limit, oversize, truncated-body-after-valid-JSON and invalid-JSON HTTP regressions. This is a LOCAL checkpoint: Rust execution and isolated-controller compilation are pending the exclusive composition qualification owner; no public push or benchmark waiver.

Require current warning-free type checks, exact intended allow/deny outcomes for Secret wire representations, nullable paused Task authority and public exposure, and UID-safe cleanup without starting custom controllers or public workloads. 74 unit/harness cases pass; no native result is claimed until hosted execution. Preserve all existing SRE/full gates and diagnostic privacy; native policy failure does not skip the unchanged bootstrap gate.

pallakatos Date: Thu, 10 Sep 2026 01:20:16 +0200 Subject: [PATCH 20/96] fix(admission): handle primary requests without a subresource field Kubernetes omits empty AdmissionRequest.subResource. Normalize only its absence to the primary-resource empty string across grant, reader-finalization and SRE token policies. Keep explicit status/token/finalize authority unchanged; no admission or permission bypass. Extend native policy qualification to install the actual grant-authority policy before primary creation, metadata and status updates, plus a regression refusing to pre-seed around admission. 75 unit/harness cases, 17 CLI contracts and Helm lint pass; expanded native qualification remains pending.

audit showed the core controller receives 403 when existing observer verification gets its consumer ReplicaSet. Add only apps/replicasets GET to the existing credential-controller role, keeping its sole core ServiceAccount binding and all UID/Deployment-lineage checks. No list/watch/write permissions or other actor bindings are added. Add a rendered-role contract regression and record the existing ephemeral workspace scope. Helm lint passes; the locked local Vitest version is unavailable and a mismatched cache was rejected, so the existing hosted CLI job must qualify that regression before merge. Native observer issuance/TLS/CNI remain mandatory. No H100/customer/main change.

Fence private issuance and both privacy RPC snapshots; genuinely rotate private service/TLS material and compare App public keys before treating a key change as rotation.

proofs, or replace TLS, network, rotation, and unauthorized-peer tests. ## Operator workflow +Private writer/observation activation is an additional review in the existing +`grant preview` / `grant apply` flow. It is not a prerequisite for ordinary +standalone core installation. The passive consumption policies apply only +after a namespace is protected for this capability. The agent-visible +`router-admin-token` is deliberately not private service authority: +private operator controls use `router-services-admin` through +`KARS_SERVICES_ADMIN_TOKEN` or `/etc/kars/services/control-token`, and reject +agent admin credentials. + +Upgraded private enrollment requires a `privateActivation` review containing +the actual root namespace, ServiceAccount and Deployment UIDs, a root template +digest, an explicit controller identity profile, current admission-bundle +UID/revisions, and reviewed namespace/consumer identities. Old review files +are rejected with a re-preview instruction rather than assigned guessed trust. +The optional historical `--controller` integration setting is not this review. + +For example, after installing the upgraded core prerequisites: + +```sh +kars credentials grant preview --namespace workspace \ + --writer addon/credential-writer --private-root kars-system \ + --private-controller-profile service-accounts \ + --observe agent --private-consumer kars-agent/Deployment/agent > reviewed-grant.json +kars credentials grant apply reviewed-grant.json +``` + +`service-accounts` pins the actual Kubernetes controller ServiceAccount UIDs. +The alternative `kcm-certificate` profile explicitly permits the authenticated +`system:kube-controller-manager` certificate principal with an absent UID, +not a similarly named ServiceAccount or arbitrary `pods.create` holder. +Only the required child-creation stage is permitted; controller UPDATE +bookkeeping requires unchanged execution templates and ownership. Explicit +registrar authority retains its existing SRE-runtime scope. + +Preview is read-only and exports metadata/digests, never private values or raw +templates. Review the referenced root and consumer templates before applying. +Additional `--private-consumer namespace/Kind/name` entries can protect an +owned runtime without granting observation access to it. An unexplained Pod, +an ownership change, a different execution template, or an incomplete inventory +blocks activation; it is not deleted or adopted to make qualification pass. +Unrelated non-consuming Pods are preserved. + +Apply rechecks the complete enforcing policy/binding specifications and their +current type-check/observation status. Existing writer authority is retired +first, including absence checks for its owned read Roles/Bindings. Namespace +protection is then enabled in `Pending`, identities/templates are rechecked, +and only approved material-consuming controller replicas are paused. All +actual material-consuming Pods, including unlabelled and terminating Pods, +must finish retirement before fresh unpredictable namespace-UID-bound epochs +are generated. Independently verified non-material consumers receive explicit +Pod UID/spec receipts. Qualified templates are stamped, and the grant is +published with the resulting receipt using its current UID/resourceVersion. +Conflicts preserve the protection and require a fresh review; there is no +unprotected rollback. + +The epoch is public freshness metadata, not authorization. Correct epochs do +not let a writer add, remove, or modify protected consumption. Admission checks +old **or** new direct/projected Secret references, env/envFrom, init/ephemeral +containers, image-pull/CSI references, privileged identities, and node-access +paths across Pod, RC, Deployment, ReplicaSet, StatefulSet, DaemonSet, Job, and +CronJob templates. Connections into activated private namespaces require +explicit operator authority; Pod log GET remains separate. Broad SAR checks +remain defense in depth, not a complete resourceNames-scoped permission proof. + +Issuance/reuse and both fresh privacy-RPC snapshots verify the current complete +bundle, root identities, namespace fence, and actual relevant consumers. +Potentially exposed service tokens and TLS identities are regenerated, not +copied. SRE Kubernetes tokens are invalidated by replacing their bound Secret +UID. A potentially exposed GitHub App key requires an operator-rotated key; +changing its PEM encoding does not count as rotation. Private +`Prepared`/consumer availability remains distinct from authorization. + +Direct Helm RPC enablement only requests the listener. It does not stage root +trust or authorize private writers; the listener remains unavailable until +generic operator activation is qualified. Direct API/Helm grant publication +must carry the same qualified receipt and live namespace fences. A prior +`Ready` value without current `WriterReady` and `PrivateConsumptionReady` +conditions is not private authority. Writer retirement (`writers: []`, or +grant disablement) retains namespace protection; no automatic deactivation +path removes it before authority retirement. + +For qualification, the canonical artifact is regenerated/checked with +`python3 tools/private-consumption-bundle.py --check`. CLI tests cover the +existing preview/apply hook and staged failures. The native +`tests/e2e/private_consumption.py::named_cases` fixture runs after operator +activation through the existing API harness: it establishes actual +resourceNames-scoped RBAC, uses inert zero-replica/suspended/no-eligible-node +bases and server-side dry-run mutations, and requires the exact intended +admission denial. It never executes a credential-reading payload. Native +qualification and independent source review remain required before sign-off. + Install the new CRD, controller and admission policies first. Install the private add-on's ServiceAccount without broad Secret or Deployment write permissions. The namespaces must already exist. diff --git a/tests/e2e/private_consumption.py b/tests/e2e/private_consumption.py new file mode 100644 index 000000000..c3e98ae9f --- /dev/null +++ b/tests/e2e/private_consumption.py @@ -0,0 +1,288 @@ +# Copyright (c) Microsoft Corporation. +# Licensed under the MIT License. + +"""Native named-RBAC qualification after reviewed generic private activation. + +Private execution attempts are server-side dry-runs.

Date: Fri, 11 Sep 2026 01:42:05 +0200 Subject: [PATCH 36/96] fix(credentials): retire root authority before TLS rotation Persist reviewed replica intent and UID-bound retirement attempts before pausing the root. Capture the TLS baseline only after complete old-consumer absence, retain it across retries, and require a fresh post-retirement public key before restoring qualified templates. Restrict retirement records to the credential operator and cover retry, CAS, named-subresource and publication failure paths.

Namespace/Sandbox/Task UIDs, executable template, source specification, +Task authorization and controller ownership must agree. An unobserved Sandbox +generation or changed reviewed Deployment resourceVersion requires re-preview. +Task authorization is the production `sha256:<64 lowercase hexadecimal digits>` +string, retained byte-for-byte in the configured identity, receipt and recovery +checks. It is not interchangeable with a bare hexadecimal structural digest. +Only the existing controller-issued `router-services-admin` token may need +rotation. Missing or customized keys, existing observer/TLS/App material, +privileged token/host access and other consumers are not adopted. + +Apply records a root-bound version-4 receipt in the **target namespace's existing +operator-only `kars.azure.com/private-root-retirement` annotation**: + +1. `Pausing` saves original suspension and replica intent, source/owner hashes, + Secret UID/version and a digest of the existing authentication key. Apply, + unlike preview, reads this one bounded private token into operator memory; + neither the token nor source credential values are printed or stored in the + receipt. UID/resourceVersion-CAS sets `spec.suspended=true` and scales the + reviewed Deployment to zero. It never sets Task `execution.launch=false`. +2.

The existing + controller `ensure_bound` quarantine/retired-consumer checks mint a genuinely + fresh admin token, preserving Secret UID. Apply waits for that token's actual + bytes to differ and for the exact controller-owned template to reference its + new Secret UID/resourceVersion and private epoch. A stamp alone cannot qualify. + Only these two template annotations may change; executable/source drift fails. +4. `Restoring` rechecks original owners/specifications, the new private key and + captured UID retirement before restoring the original suspension intent. + `Qualified` requires observed Deployment readiness (or the original suspended + zero replicas). Supported replica intent is the controller's zero/one policy. + +The controller independently honors this operator-owned in-progress receipt. +It forces zero replicas until `Restoring`, verifies the original raw Sandbox/Task +specification and owner/generation bindings, and checks the actual new token +digest and Secret/template versions at the restore boundary. Concurrent tenant +unsuspension cannot bypass the recorded retirement or substitute a different +source. Completed scopes return to the existing controller lifecycle; unrelated +core runtimes without this receipt are unchanged. +The recorded Deployment incarnation is checked before **both CREATE and UPDATE**, +including completed v4 scopes. If it disappears or is replaced, no replacement +is adopted or created; explicit operator recovery is required. Ordinary core +creation and existing v3 scope handling do not acquire this v4 identity fence. + +Re-preview after a CAS conflict or lost response resumes the recorded attempt, +original intent and epoch; it cannot adopt changed templates/specifications or +invent missing retirement evidence. Failure preserves suspension and recovery +records. Task, Sandbox, namespace, source bundles, projections, agent keys and +persistent volumes are not deleted or replaced. **Pod-local ephemeral state, +including `emptyDir`, is restarted**, as preview explains; this is not a backup +or live migration facility. Already-enrolled observer/App runtimes require their +separate explicit rotation workflow.

For a +Task-owned runtime this is the Task, not its materialized Sandbox. A missing +annotation on the child alone therefore does not establish a bundle failure. + +If a successful, acknowledged empty bundle CREATE is followed by a target +resourceVersion conflict, core can retry only the metadata anchor, at most +twice, while retaining that exact CREATE UID/resourceVersion and rechecking +current ownership, grant, source and binding authority.

Effective HTTPS port and IP comparison fixes a false mismatch; positive scoped transport facts do not diagnose the unresolved native timeout. Transport, TLS, authentication, and production deadlines are unchanged. Hosted Rust qualification is still required.

For installed Cilium, manage only a namespaced API-entity policy with validated ports and effective selectors. Preserve original namespace/claim/UID/RV fences, remove stale extensions, and retain a cleanup hint for interrupted retirement.

Validate official checksums before executable publication, bound HTTPS acquisition and transient retries, and separate metrics manifest acquisition from one-shot Kubernetes apply. Keep global deadlines, integrity checks and runtime assertions; exercise real partial-transfer cleanup and exact topology preservation.

Explicitly account for strict data, legal files, generated artifacts and upstream ownership without corrupting payloads or changing licensing. Restrict generated coverage to reviewed exact paths; reject unknown authored formats. Keep existing checker/applier entrypoints and test enforcement.

Helm templates (including template YAML and +`NOTES.txt`) use Go-template comments with **no surrounding output whitespace**, +not YAML comments that can interact with `{{- ... -}}` trimming. + +Use `scripts/apply-copyright-headers.sh` rather than rewriting files manually. +It preserves original body bytes, line endings, file modes, author notices, +shebangs, Python encoding cookies, Docker parser directives, Markdown frontmatter, +CSS charset directives and frontend directive prologues. It is idempotent. +Both existing commands share `ci/copyright_headers.py` (Python standard library). +`ci/check-copyright-headers.sh` checks **every tracked file**, and fails on unknown +formats, missing notices or unsafe inputs. Run the format regression tests with +`python3 ci/tests/copyright_headers_test.py`. + +Some files cannot safely receive literal comments. `ci/copyright-coverage.json` +explicitly records coverage under the existing root `LICENSE`/`NOTICE`: strict +JSON, lockfiles, binary/image/presentation assets, managed drawings, recordings, +encoded certificate fixtures, empty markers, literal prompt inputs and the +Helm policy embedded verbatim into a resource string remain +byte-identical. This is license coverage, **not a claim that binaries have text +headers**. Vendored packages, upstream assets, generated output and third-party +license texts retain their own ownership and notices; do not prepend Microsoft +ownership to them or replace original attribution. The policy does not relicense +third-party content. New special formats require a reviewed rule, not a blanket +directory exemption for first-party sources. + +Generated status is never inferred from names such as `build`, `target`, `dist`, +`coverage`, `.turbo`, `node_modules`, or the `.d.ts` suffix. Generated coverage +requires an exact reviewed file entry with producer/provenance and a notice +reference in `ci/copyright-coverage.json`. The current entries are only +`tools/headlamp-plugin/dist/main.js` and `tools/headlamp-plugin/dist/package.json`. +Handwritten sources in output-named directories and authored declarations need +normal headers; unknown first-party formats still fail. + +The embedded Helm AGT policy has a raw-byte digest contract: the controller +publishes its exact bytes as `agt-profile.yaml`, and the router confirms a +length-prefixed SHA-256 over the filename and body. Adding a YAML comment would +change that digest even if the parsed policy were identical, so this exact +payload is explicitly covered without a literal header. + +The checker prints coverage totals, including non-header categories. Pass +`--verbose` to list every non-header path and reason, or +`--report copyright-report.json` for a complete machine-readable inventory. +The applier accepts the same options; its report includes insertion offsets, +lengths and before/after SHA-256 hashes. Reports are local artifacts, not source +files to commit.
