documentation changes WIP

Refreshes Context7's index of the VyOS documentation library on
completion of 'Update version tags', mapping rolling/circinus/sagitta to
Context7 variants rolling/1.5/1.4 respectively.

Triggered via workflow_run because GITHUB_TOKEN-driven tag pushes from
update-version-tags.yml do not fan out to downstream workflows.
workflow_dispatch added for ad-hoc and bootstrap refreshes.

CR finally got credits and posted three substantive findings on b0fdd07.

1. CRITICAL — line 281, model: input is silently ignored.
   anthropics/claude-code-action@v1 removed the top-level `model`
   input; the migration guide says model selection now travels via
   `claude_args: --model <name>`. With the old form, the action used
   its DEFAULT model on every run instead of the pinned claude-opus-4-7,
   defeating the version pin entirely. CR even ran a web query and
   actionlint to verify (actionlint output: "input 'model' is not
   defined in action 'anthropics/claude-code-action@v1'"). Moved
   --model claude-opus-4-7 into claude_args.

2. MAJOR — line 135, secrets template-expanded into shell text.
   `[ -z "${{ secrets.VYOS_APP_ID }}" ]` lets GH Actions do
   ${{ ... }} expansion BEFORE bash parses the script. A secret
   containing a single quote, backtick, or $ would either break the
   test syntactically or be evaluated by the shell. The same hygiene
   that justifies the prepare/validate split applies here. Moved
   the three secrets to an env: mapping; the script now reads
   "$VYOS_APP_ID" etc., handed to bash as already-quoted env vars.

3. NIT — line 7, concurrency group brittle outside PR events.
   `github.event.pull_request.number` is empty on workflow_dispatch
   or schedule; the group would collapse to "ai-validation-" and
   unrelated runs cancel each other. Defensive fix: fallback to
   `github.ref`. Today the workflow only fires on
   pull_request_target so this is purely future-proofing.

Same changes being synced to canonical scripts/ai-validation.yml
in vyos-docs-opus-reviewer PR vyos#13.

Two more Copilot findings on b0fdd07:

1. line 35 — defense in depth: prepare on self-hosted is risky.

   Even though the prepare job doesn't execute fork code (it only does
   git diff / git show / file reads — never pip install, npm install,
   build, or tests), Copilot's right that running fork content on a
   self-hosted runner with internal-network access is the wrong
   default. A future maintainer who innocently adds a "run linter"
   step to prepare could turn it into an attack vector against the
   VyOS internal network or a persistence mechanism on the host.

   Moved prepare to runs-on: ubuntu-latest. GitHub-hosted runners are
   ephemeral, isolated, and have no path to internal services. The
   trusted validate job stays on [self-hosted, web]; the split-job
   artifact bridges the trust boundary as before.

   Side benefit: removes the runner-side dependency on jq/gh/git
   for the prepare job (those are pre-installed on ubuntu-latest).

2. line 149 — skip-notice discoverability.

   When secrets are missing the workflow only emits ::notice:: in
   the run logs. Contributors checking the PR timeline have no
   reason to click through to the run page. Added a new step that
   posts an actual PR comment via gh pr comment when skip=true,
   running with GH_TOKEN: ${{ github.token }} (the validate job
   already has pull-requests: write).

   The ::notice:: annotation is preserved alongside.

If CONTEXT7_API_KEY is unset or empty (e.g. secret not yet configured),
emit a clear error message rather than letting curl fail with a generic
auth error. The `:-` guard is needed because `set -u` would otherwise
abort before the `-z` test when the variable is truly unset.

Tag VyOS-Networks/vyos-docs-opus-reviewer/reviewer-v1.0.1 was
published after PR vyos#13 merged on the reviewer side. v1.0.1 brings:
- Self-hosted runner workspace cleanup
- setup-uv (Debian 12 + Python 3.12 compat)

The branches.json map and Python source consumed via REVIEWER_REF
are unchanged from v1.0.0, so this bump is a no-op functionally
for the validate job — but it ensures the deployed workflow pulls
from a stable, post-cleanup-merge state of main rather than the
older v1.0.0 tag.

User direction: GitHub-hosted ubuntu-latest is not available in this
environment. The runner pool is Debian 12 self-hosted (web-runner-01,
web-runner-02). prepare must run there too.

Pushing back on Copilot's defense-in-depth finding (line 35) with
explicit threat-model reasoning documented in the workflow comment:

- prepare does not execute fork code. Only git fetch / git diff /
  git show / file reads. No pip install, no npm install, no build,
  no test. Adding any of these would require a deliberate code
  change in this file that a reviewer must approve.
- No secrets are referenced in prepare. Even a presence-check would
  leak the value into the runner environment.
- persist-credentials: false on the merge-ref checkout keeps the
  default GITHUB_TOKEN out of fork-readable .git/config.
- The atos-actions/clean-self-hosted-runner step (`if: always()`)
  wipes the workspace after every job regardless of exit state.

The split-job artifact still bridges the trust boundary to validate.
validate remains the only place where secrets are referenced.

The skip-notice `gh pr comment` step from a22df7d is preserved —
that's an independent discoverability improvement.

Without explicit timeouts, a stalled TCP handshake or slow server response
blocks the workflow indefinitely. --connect-timeout 10 bounds the TCP/connect
phase; --max-time 60 caps total request duration. Both are within reasonable
limits for a refresh POST that normally completes in well under a second.

CodeRabbit nitpick on PR vyos#1947: actionlint flags `runs-on: [self-hosted,
web]` with `label "web" is unknown` because `web` is a custom label for
the VyOS-Networks org-managed self-hosted Debian 12 runner pool, not a
known GitHub-hosted label. Adding `.github/actionlint.yaml` with the
`self-hosted-runner.labels` list is the upstream-documented way to
suppress the false positive without disabling the linter.

No behavioral change.
ci: AI Validation rewrite — MyST + split-job + branch map
Context7's API expects the bare repo identifier 'vyos/vyos-documentation'
(verified at https://context7.com/vyos/vyos-documentation), not the
leading-slash form. The auto-fired workflow_run cycle after vyos#1950 / vyos#1948
/ vyos#1949 merged returned HTTP 404 on all three variants because of the
extra slash.

Spec: ~/.claude/specs/2026-05-10-context7-github-actions-integration-design.md
(spec narrative referenced Codex's round-1 advice to use leading slash;
that advice was empirically wrong against the live Context7 API).

Two improvements to .github/workflows/update-version-tags.yml, bundled
because they touch the same code block:

1. HEAD-equivalence guard. GitHub's "Re-run jobs" replays the original
   event SHA, which for this workflow would move tag rolling/1.5/1.4
   backward to a stale commit. Compare github.sha against the live
   branch HEAD via the API and exit 0 with a log line if they differ.

2. PATCH-first with 404-only fallback to POST. The previous "GET probe
   then PATCH or POST" pattern silently fell through to POST on any
   gh-api error (auth, rate-limit, 5xx), which would attempt to create
   a tag that already exists and mask the real failure. Now the
   fallback to POST fires only on HTTP 404; every other error is
   re-emitted to stderr and fails the job.

Backport to circinus and sagitta after merge.

Copilot review on PR vyos#1953 surfaced an edge case the HEAD guard alone
doesn't fully cover: with cancel-in-progress: true and a per-branch
concurrency group, a stale "Re-run jobs" replay can cancel the
in-progress run for the current branch HEAD. The stale re-run then
hits the HEAD guard and exits 0, leaving the tag un-advanced until
the next push.

Including github.sha in the concurrency group means different commits
land in different groups and never cancel each other. Same-SHA re-runs
still deduplicate (they share the group), and the HEAD guard handles
the case where a stale re-run beats the current-HEAD run to start.

ci: drop leading slash in Context7 libraryName
ci: harden update-version-tags against stale re-runs and silent failures
CodeRabbit minor finding on the paired canonical PR
(VyOS-Networks/vyos-docs-opus-reviewer#14): the `Notify on PR (when
skipping)` step posts a fresh `gh pr comment` on every `synchronize`
event. On a fork PR to a repo where the AI-validation secrets are not
configured, every push during PR iteration would duplicate the skip
notice, flooding the conversation thread.

Gate the step to fire only on `opened`/`reopened` — those are the
moments where the PR author benefits from being told once that
validation is skipped. Further pushes add no new information; the
workflow-run-page `::notice::` annotation is still emitted on every run
for maintainers.

`concurrency.cancel-in-progress: true` alone is not sufficient — most
synchronize events would be cancelled before the notify step ran, but
any run that completed the notify step before the next push still
posts the comment.

ci(ai-validation): gate skip-notice comment on opened/reopened only
The `vyos` org does not have self-hosted runners labeled `web` (those
live in the VyOS-Networks org pool and only serve repos there). Every
AI Validation run queued since vyos#1947 merged sat in `queued` state
indefinitely with no runner picking it up — observed across all recent
PRs (vyos#1955 mergify backports, vyos#1956, plus several yuriy/* branches).

Switching both `prepare` and `validate` jobs to `runs-on: ubuntu-latest`:

* Removes the host-isolation half of the prepare-job rationale comment
  and replaces it with the ephemeral-VM rationale (cross-run state
  leakage is impossible on a fresh GitHub-hosted VM).
* Removes both `atos-actions/clean-self-hosted-runner` cleanup steps —
  GitHub-hosted runners are ephemeral, the action is a no-op there at
  best and a failure mode at worst (it expects self-hosted workspace
  patterns that don't exist on hosted runners).
* Tweaks one comment that mentioned `/proc/<pid>/cmdline on the self-
  hosted runner` to be runner-agnostic.

Also removes `.github/actionlint.yaml`. It was added in vyos#1947 to silence
actionlint's "label 'web' is unknown" false positive — with no workflow
in this repo now using `[self-hosted, web]`, the file is dead code.

The canonical reference at `VyOS-Networks/vyos-docs-opus-reviewer/scripts/
ai-validation.yml` intentionally diverges: that repo IS in VyOS-Networks
and has access to the `web` self-hosted pool, so its canonical keeps
`runs-on: [self-hosted, web]` and the cleanup steps. The deployed
file's REFERENCE COPY header comment block in the reviewer repo will be
updated in a follow-up to note that the deployed file may use different
runners per host repo's pool availability.

No security regression — the trust boundary on prepare is enforced by
no-fork-code-execution, no-secrets-referenced, persist-credentials:false,
and the split-job artifact, all of which are unchanged. Adds the implicit
host-ephemerality guarantee of GitHub-hosted runners.
PR vyos#1953 added github.sha to the concurrency group key to prevent stale
"Re-run jobs" replays from cancelling the in-progress current-HEAD run.
Copilot review on the sagitta backport (vyos#1955) caught the regression
that introduced: per-SHA groups mean back-to-back pushes A then B run in
parallel rather than serializing, and if run-A's force-PATCH lands
after run-B's, the tag rewinds to A.

Fix: per-branch group + cancel-in-progress: false.

- Concurrent runs serialize, so commit order is preserved on the tag.
- Stale "Re-run jobs" replays queue behind the current run, then hit
  the HEAD-equivalence guard in the job body and exit 0 — the guard
  (added in PR vyos#1953) is the safeguard for that case, not the
  concurrency group.
- Tag-move work is fast (~5s); serial execution under back-to-back
  push bursts is acceptable.

The post-merge auto-fired runs from vyos#1948/vyos#1949/vyos#1950 all returned 4xx
errors. Diagnostic curls against the live Context7 API revealed two
issues:

1. The 'branch' parameter addresses variants by their underlying Git
   branch name (rolling/circinus/sagitta), not by their tag display name
   (rolling/1.5/1.4). Sending 'branch: "1.5"' returns:
     HTTP 404 {"error":"branch_not_found","message":"Branch '1.5' not found"}

2. The default variant refreshes when the 'branch' field is omitted
   entirely. Sending 'branch: "rolling"' returns:
     HTTP 400 {"error":"branch-not-found","message":"Failed to refresh library"}
   But omitting the field returns:
     HTTP 200 {"message":"Refresh started successfully"}

3. (Bonus, validating vyos#1951 was wrong direction.) The libraryName must
   include the leading slash: 'libraryName: "/vyos/vyos-documentation"'
   per Context7's docs. Without the slash returns:
     HTTP 404 {"error":"library_not_found"}
   This commit restores the leading slash that vyos#1951 incorrectly removed.

Changes:
- Restore leading slash on libraryName ('/' + github.repository).
- Drop the tag-name mapping in the case statement; pass head_branch
  directly as the branch value.
- Omit the 'branch' field when head_branch is 'rolling' (default variant).
- workflow_dispatch input renamed from 'version' to 'branch'; choice
  options changed from [rolling, '1.5', '1.4'] to [rolling, circinus, sagitta].
- Simplified concurrency expression (no longer needs the rewrite chain).
- Documentation comment updated to explain the branch-name addressing.

Spec: ~/.claude/specs/2026-05-10-context7-github-actions-integration-design.md
This is the 'fallback mapping' path that the spec's variant table already

Copilot review on the paired add-to-circinus PR (vyos#1959) flagged two
documentation drifts from the ubuntu-latest switch in this PR:

1. Line 65: comment referenced a 'cp loop' but the implementation has
   used 'git show HEAD:<path>' as the bundling mechanism since
   1ea164f. Reworded to describe the bundling loop accurately.

2. Line 270: comment explained why setup-uv was used 'on Debian 12' —
   stale now that the workflow runs on ubuntu-latest. Reworded to
   describe the actual reason setup-uv is preferred (fast interpreter
   provisioning + portable to self-hosted Debian if this workflow
   ever moves back).

Documentation-only change. No behavioral effect.
ci: fix Context7 refresh — branch-name addressing + default-variant handling
Both Copilot and CodeRabbit flagged the same hole on PR vyos#1958: GitHub's
"Re-run failed jobs" can execute retag in isolation, skipping
check_head. If the branch HEAD advanced since the original run, the
isolated retag would PATCH the tag to a stale github.sha.

Add the same HEAD-equivalence guard inside retag, immediately before
the PATCH/POST. Defense-in-depth — both jobs check, so neither full
re-runs nor selective retag re-runs can move the tag backward.

🤖 Generated by [robots](https://vyos.io)
Post-vyos#1961, the rolling auto-refresh (default variant, no field) succeeds,
but workflow_dispatch for branch=circinus/sagitta still 404s. Further
empirical curls against the live API revealed:

  POST /api/v1/refresh
  {"libraryName":"/vyos/vyos-documentation","branch":"circinus"}
  → HTTP 404 {"error":"branch_not_found","message":"Branch 'circinus' not found"}

  POST /api/v1/refresh
  {"libraryName":"/vyos/vyos-documentation","tag":"1.5"}
  → HTTP 200 {"message":"Refresh started successfully"}

So Context7's API addresses variants by their REGISTRATION TYPE on the
dashboard:
  - default variant (rolling)     → omit both 'branch' and 'tag'
  - tag-backed variants (1.5/1.4) → 'tag' field
  - branch-backed non-default     → 'branch' field

The dashboard shows 'rolling' with a branch icon and '1.5'/'1.4' with tag
icons. The 'branch' field only addresses entries registered as branches;
'tag' addresses entries registered as tags. This is undocumented in the
public GitHub Actions integration page but works against the live API.

Changes:
- Restore the variant mapping (circinus → 1.5, sagitta → 1.4) — that
  matches the actual dashboard variant names. vyos#1961 had dropped this in
  favor of branch-name passthrough, which only worked for the default.
- Switch the non-default payload from 'branch: <name>' to 'tag: <name>'.
- workflow_dispatch input renamed back from 'branch' to 'variant'; choices
  back to [rolling, '1.5', '1.4'].
- Restore the variant-keyed concurrency expression (with rewrite chain).
- Update the documentation comment to record the empirical API semantics.

actions/upload-artifact silently omits empty directories. On a PR that
changes no docs/**/*.md (workflow tweaks, README edits, config), the
prepare job's _changed_md/ ends up empty and is dropped from the
artifact. The validate job downloads the artifact, then "Pass 1 —
deterministic checks" tries to start with `working-directory:
_changed_md`, which doesn't exist, and bash fails before any in-step
short-circuit can run.

raised these findings on the paired add-to-circinus PR vyos#1959 (where
the same file was being added to the circinus branch); since the file
contents are byte-identical across rolling/circinus/sagitta, applying
the same fixes here.

  1. SHA-pin actions/checkout@v6 (x4), actions/upload-artifact@v4,
     actions/download-artifact@v4, anthropics/claude-code-action@v1.

  2. Reject paths containing control characters (NUL/CR/LF) in
     changed-md.z and changed-rst.z before `tr '\0' '\n'` converts
     them to newline-delimited manifests. A fork PR committing
     `docs/foo<LF>bar.md` would otherwise split into two logical
     lines, masking the real file from line-based consumers.

  3. Pin reference-DB download to `tag: ${{ env.REVIEWER_REF }}`
     (was `latest: true`). Aligns DB version with the pinned
     reviewer code; a future reviewer-v1.x.x release with a DB schema

* T9208: add scutum to docs CI branch enumerations

The scutum docs branch (VyOS 1.6 train) was cut from circinus on
2026-08-13. Register it in the branch enumerations that gate CI on the
default branch:

- context7-refresh.yml: add scutum to the push-trigger branch list, the
  workflow_dispatch choice options and the defence-in-depth variant
  allow-list, so a docs push on scutum refreshes its own Context7
  variant instead of being dropped.
- context7.json: add a `scutum` entry to `previousVersions`. Context7
  registers branch variants from this file on the default branch; a
  refresh with `branch: "scutum"` 404s until that registration exists.

Enumerations only — no behaviour change for the existing rolling,
circinus and sagitta variants.

the version scutum now serves. Add the scutum row and drop the stale

Stale claims removed:

- "Auto-reviews are disabled on this repo — both bots are triggered

Current reality documented instead:

- CodeRabbit reviews automatically on the draft -> ready flip and on

- CodeRabbit commonly edits its walkthrough comment in place rather
  than posting a new one, so the absence of a new comment is not the
  absence of a review.
- A rate-limited CodeRabbit silently drops that review; commenting
  `@coderabbitai review` after the window resets is the only case
  where a manual trigger is appropriate.
- Copilot is no longer part of the workflow and should not be
  invoked. Threads from a manual invocation by someone else are
  addressed like any other reviewer feedback.

Also adds the missing AI Validation entry to the CI list: it
cross-checks changed docs Markdown against the vyos-1x source tree for
the corresponding branch and posts inline plus summary review
comments, runs only when a PR touches docs Markdown, and skips when
the required repository secrets are unavailable or the PR is a
Mergify-authored backport.

README.md's pointer to the contributor guide is updated in the same
pass to drop Copilot from the named workflow. Note that
.github/copilot-instructions.md is a symlink to AGENTS.md, so it
picks up the change automatically.

    • Added IPv4/IPv6-aware address validation and configuration rendering.
    • Added IPv6 support for DHCP high-availability source and remote peer addresses.
  • Bug Fixes

    • Corrected IPv6 formatting in generated service configuration and peer URLs.
    • Prevented mismatched address families between synchronization peers and listen addresses.

Walkthrough

The change adds IPv4 and IPv6 support to conntrack synchronization and DHCP high-availability configuration. It updates validation, generated configuration, Kea peer URLs, and smoke tests.

Changes

Dual-stack service configuration

Layer / File(s) Summary
Dual-stack configuration contracts
interface-definitions/include/dhcp/dhcp-server-common-config.xml.i:158, interface-definitions/include/dhcp/dhcp-server-common-config.xml.i:182-192, interface-definitions/service_conntrack-sync.xml.in:151-181
Configuration definitions now accept IPv4 and IPv6 source, peer, listen, and multicast addresses.
Address-family validation
src/conf_mode/service_conntrack-sync.py:29-30, src/conf_mode/service_conntrack-sync.py:73-114
Validation selects the peer or multicast address family and rejects synchronization or listen addresses from a different family.
Dual-stack configuration rendering
data/templates/conntrackd/conntrackd.conf.j2:15-36, python/vyos/template.py:911-923
Conntrackd rendering selects IPv4 or IPv6 directives and removes CIDR suffixes. Kea peer URLs bracket IPv6 addresses.
IPv6 smoke-test coverage
smoketest/scripts/cli/test_config_dependency.py:22-136, smoketest/scripts/cli/test_service_dhcp-server.py:47-64, smoketest/scripts/cli/test_service_dhcp-server.py:1242-1251
Smoke tests configure IPv6 addresses, inspect generated conntrackd settings, verify IPv6 service operation, and check bracketed Kea peer URLs.

existing conntrack configuration setup to add a multicast scenario: remove the
peer setting, configure the IPv6 mcast-group, commit, and verify the generated
IPv6_address directive plus the running conntrackd.service state. Keep the
existing IPv6 unicast assertions intact and use the same CLI/configuration
helpers already used by the test.

Timestamp: 2026-05-26T06:03:59.703Z
Learning: In VyOS smoketests that verify processes running inside a VRF using iproute2, remember that `ip vrf pids <vrf>` outputs one entry per line as `<pid> <process_name>` (e.g., `300431 nginx`), not PIDs alone. Therefore, assertions should check for the presence of the expected process name in the command output (e.g., `assertIn(PROCESS_NAME, cmd(f'ip vrf pids {vrf}'))`) rather than trying to match PID-only output.

Timestamp: 2026-05-26T06:04:29.163Z
Learning: In VyOS smoketest scripts under `smoketest/scripts/cli/`, it is intentional to call `self.cli_delete(['vrf'])` in both `setUpClass` and `tearDown` to wipe the entire VRF subtree and ensure a clean slate. During code review, do not recommend narrowing the delete to specific VRF identifiers or name subsets (e.g., `['vrf', 'name', 'mgmt']`)—the broad teardown behavior is the established project-wide pattern for these tests.

File: smoketest/scripts/cli/test_vpp.py:0-0
Timestamp: 2026-06-29T12:13:51.293Z
Learning: When reviewing vyos-1x code that parses or asserts VPP CLI output (e.g., smoketest CLI tests and VPP op-mode code), do not flag the token spelling "Forwrd" / "U-Forwrd" as a typo. It is intentionally preserved verbatim from the upstream VPP CLI text shown by commands like `vppctl show bridge-domain ... detail`. This misspelling is centrally allowlisted (vyos/.github#153) for that specific VPP-CLI context, so typo-review comments should exclude "Forwrd" when it originates from that VPP output.

Timestamp: 2026-07-28T08:34:45.374Z
Learning: For VPP smoketest CLI scripts in smoketest/scripts/cli that use a single-node topology (e.g., no peer/ping target on interfaces like eth1) and validate dataplane behavior via VPP API assertions (not packet forwarding), reviewers should not require ping/packet-forwarding coverage. Only add/flag ping/forwarding checks if the test topology is extended with a traffic/forwarding endpoint (e.g., configured peer(s) or a traffic path that should generate observable packet behavior).
