Give the Runner a way to read each component's CURRENT version so it can be
compared against the release sources already wired. Three pure extractors turn
raw system text into an updates.Version, each fail-closed:
- versionFromCLI — a `<tool> --version` banner (k3s, cloudflared)
- versionFromImageRef — a container image tag (felis-api)
- versionFromJarName — a proxy jar filename (velocity)
sysGatherer routes each Topology component to the right extractor over an
injected seam; every path is exercised with a fake runner, mirroring how the
release sources are proven against httptest.
The load-bearing case is k3s: its Git tag "v1.36.2+k3s1" parses stable, but a
registry cannot store '+', so the same build ships as image tag "v1.36.2-k3s1",
which parses as a prerelease unless repaired. versionFromImageRef normalizes
"-k3sN"/"-rke2rN" back to "+", so an image read and a CLI read agree instead of
the image masquerading as a prerelease and being barred from comparison.
Honest runtime state after this slice — a green suite is not "the updater runs
against real infra": only the CLI seam (execRunner) is wired, so of the four
tracked components just cloudflared is live end to end (gatherable AND
Scheduled/appliable). k3s is CLI-gatherable but Notify-only. felis-api and
velocity are NOT yet runtime-gatherable: their producing seams — a k8s read of
the control-plane Deployment image, and an off-cluster jar inspection — are left
nil, so both surface an explicit "gather seam not wired" error rather than a
wrong version. felis-api self-update is therefore not functional yet.
Remaining integration (tracked in doc.go): the two producing seams, the concrete
Notifier (SMTP + in-game), the Applier (image bump, cloudflared swap), the
`felis update` CLI + CronJob entry point, and the runtime append of the Pinned
Minecraft fleet.
Give RoutingSource its second upstream so every non-pinned component now
resolves a real latest-stable: Velocity via PaperMC (already wired), and
felis-api, k3s and cloudflared via the GitHub REST API.
github.go queries /repos/{repo}/releases/latest (one request, rate-limit
friendly) and fails closed: a transport error, a non-200 status (404 = no
stable release), an undecodable body, a draft/prerelease flag, or an
unparseable / prerelease-parsing tag all return an error, never a zero
version. It sends the User-Agent GitHub requires (a UA-less request is
403'd) and tolerates the two live tag styles -- cloudflared's CalVer
"2026.6.1" and k3s's v-prefixed, build-tagged "v1.36.2+k3s1" -- while
String() keeps the raw tag for the report.
source.go routes sourceGitHub to it and drops the errGitHubNotWired stub;
velocity still routes to PaperMC.
Tests: github_test.go covers both tag styles, the User-Agent gate, and
fail-closed on 404 / prerelease-flag / unparseable tag, with fixtures
captured from api.github.com on 2026-07-05. runner_test.go now drives
PaperMC and GitHub through dual httptest servers end to end with no source
degrading to an error.
doc.go re-tiers the verification boundary: both release sources are now
built and live-grounded; the VersionGatherer's version-extraction core is
the next verifiable slice (logic over an exec seam, not pure I/O); the
genuine I/O remainder is the Notifier, Applier and felis update CLI/CronJob.
felis-api's coord is still a placeholder slug, so that component is dark at
runtime until a real repository is configured.
An out-of-band curl of the live Fill v3 endpoint contradicted two claims the
previous commit shipped and surfaced a mis-tiering:
- User-Agent is NOT enforced: fill.papermc.io/v3/projects/velocity returned
HTTP 200 to a bare curl UA. The comments claimed a generic UA "is refused"
and the API "REQUIRES" a contact UA. Reword to what is true — PaperMC's usage
policy asks for a descriptive UA and may block generic ones, but sending it is
etiquette/defensive here, not a gate Felis depends on.
- The test fixture's shape was invented, not captured: the real "versions"
object groups the entire 3.x line under a single key "3.0.0", not the
per-minor keys the fixture used. Replace it with the real body (keys and
version strings as returned). The key-agnostic parser already produced the
right answer, and an independent max-stable check confirms 3.4.0.
- Re-tier doc.go: the GitHub Releases source is verifiable-here (the same
httptest-testable shape as PaperMC), not integration remainder. It is why
3 of 4 components report "latest unknown" today and is the next verifiable
slice — the release-source work is only ~half done until it exists.
No production logic changed. WSL oracle: build + vet clean, internal/updater
10/10, full tree go test RC=0 (19 ok, 0 fail).
internal/updates is a pure, fakes-tested decision core with no production caller,
so nothing could produce its "版本号状态" report. Add internal/updater as that caller:
- topology: the fixed platform components and their user-set policies (felis-api
and cloudflared Scheduled+manageable; k3s Notify, high-blast-radius single node;
velocity Notify, off-cluster and unmanageable). Minecraft is pinned by ABSENCE,
never force-tracked here, appended from the live fleet at runtime.
- PaperMC Fill v3 release source: the v2 API (api.papermc.io) was retired
2026-07-01 and returns HTTP 410, so this targets fill.papermc.io/v3, sends the
required non-generic User-Agent, and returns the newest STABLE version, filtering
the -SNAPSHOT/rc prereleases the plan would otherwise suppress. Its test fixture
is captured from the live v3 response shape (2026-07-04).
- RoutingSource: the single ReleaseSource updates.Run requires, dispatching
velocity to PaperMC and returning errGitHubNotWired for the GitHub-backed
components so they degrade to "latest unknown" honestly, never a fabricated one.
- Runner: gather current versions (seam) -> assemble Components -> updates.Run ->
Report; report-only when notifier and applier are nil.
Verification boundary: the parse/plan/compose logic is unit-tested (httptest +
fakes, fixture grounded in the live v3 shape). Live network/TLS/User-Agent
enforcement, the GitHub Releases source, the concrete version gatherer, the
notifier and applier, and the felis update CLI/CronJob remain integration work,
enumerated in doc.go.
