Test: Add a fakeSystemctl/fakeLoginctl harness for the Linux service path - #1080
Conversation
…path loadService, controlService, supervisorRunning, and unloadService checked runtime.GOOS directly, so none of their Linux logic could be exercised from a non-Linux host, or against systemd's real is-active vocabulary (activating/failed/deactivating) rather than just the two extremes. Refactor all four to take goos explicitly, mirroring the fix already applied to renderUnitFor for the same reason. Add cmd_service_systemd_test.go: a fakeSystemctl/fakeLoginctl PATH-decoy harness mirroring fakeLaunchctl, with 22 subtests covering daemon-reload/enable failures, the linger enable/marker lifecycle, unloadService's marker-gated disable-linger, and controlService's verb-per-action mapping. supervisorRunning's is-active handling for the non-"active" states turned out to already be correct; it was just unverified until now.

Good complement to the real-systemd integration test in #1076 — this fakeSystemctl/fakeLoginctl harness mirrors the existing fakeLaunchctl pattern, uses t.TempDir()/t.Setenv for automatic cleanup with no shared-state races, and has meaningful table-driven assertions including error paths (not just happy path). The fidelity risk (fake vs. real systemd semantics) is explicitly acknowledged in the PR body as complementary to #1076's real-systemd coverage rather than a substitute. No must-fix issues (not approving since this is my own PR).
Areas reviewed: Go source (goos parameterization refactor), Go test harness, docs
Commits: 2 commits, both signed off
CI status: passing
Two CodeRabbit findings on #1080: - The daemon-reload/enable and show-user fakes matched positionally ($2/$1). If the real call sites ever reorder arguments (e.g. a new flag inserted before daemon-reload), the fake would silently take the wrong branch instead of failing with a clear "shape changed" signal. Switched all five to `case "$*" in *pattern*)`, matching anywhere in the argument list regardless of position. - The is-active fakes hardcode exit 3 for every non-active state with no comment on why that value doesn't matter. Added one: supervisorRunning's Linux branch only checks err != nil and stdout content, never a specific exit code, so any nonzero value exercises the same path. All 22 subtests still pass.

Refactoring four platform functions to take goos explicitly is the right approach — it makes the Linux path testable from any host OS and matches the precedent set by renderUnitFor. The fakeSystemctl/fakeLoginctl harness is clean and the 22 subtests cover the important branches.
One observation on fakeSystemctl and fakeLoginctl: each creates an independent t.TempDir() and prepends it to PATH. When both are called in the same test (e.g. TestLoadService_Linux's linger subtests), PATH gets two prepended entries. That works correctly because each stub only contains its own binary — but if a future test case needs to override both from a single directory, the two-dir pattern would need to change. A brief comment noting the independent-dirs design would help the next author understand it's intentional.
All checks pass. Ready for human review.

…ntentional CodeRabbit review on #1080: a test using both fakes ends up with two prepended PATH entries, one per helper's own temp dir.

Real bug caught in the doc, not the code: two checklist bullets are marked CLOSED / Landed 2026-09-17 when both fixes are still sitting in open PRs — and I verified TimeoutStopSec is absent from the entire tree at this PR's head and on main. For a doc whose stated purpose is "so the findings don't have to be re-derived later," that's the one thing it can't get wrong. One-line fix.
The Go work is solid. I read all four refactored functions at head and confirmed no residual runtime.GOOS in any of them (the remaining three uses — supervisorName, renderUnit, launchdUsable — are untouched and out of scope), all 6 call sites updated, and every test assertion matches the real code paths: is-active's err != nil && st == "" fallback, the disable --now / enable --now / restart verb table, the marker-gated disable-linger. servicePathsFixture is t.TempDir()-backed, so the marker writes never touch a real ~/.cortex, and every path that can reach systemctl/loginctl installs a fake first — no test mutates a developer's or a CI runner's systemd state. The observation that supervisorRunning's non-active handling was already correct and merely unproven is exactly the kind of finding worth recording.
Areas reviewed: Go (source + tests), Docs
Agent/IDE config (.claude/.vscode): none
Commits: 4, all signed off; Assisted-By trailer (correct), no banned trailers; subjects ≤70 chars, conventional prefixes
CI status: all 25 checks passing (Spellcheck skipped)
Blocking only on the three doc status claims below. Everything else is a suggestion or a nit.
Four CodeRabbit findings, all verified against actual code before fixing: - must-fix: the plan doc's Status header, bullet 6, and bullet 7 read as if this branch delivered the TimeoutStopSec fix and the fakeSystemctl/fakeLoginctl harness + goos refactor. It doesn't — confirmed via `git diff main...this-branch`, neither touches cmd_service_platform.go's function signatures nor adds that harness file. Both live on separate, not-yet-merged sibling PRs (#1079, #1080). The doc is shared across three independently-reviewed branches and each copy drifted to claim collective progress as if it were local. Corrected the Status header, bullets 6/7, Cross-cutting themes 1/3, and Suggested next steps 1/2 to attribute that work to the correct PR instead of this one. - The pre-emptive stop() call before t.Cleanup(stop) can never match a real leftover: the unit name embeds this process's own pid, unique per run, so there's nothing with that exact name to have been left behind. It only produces spurious "cleanup:" failure logs on every normal passing run (confirmed from this PR's own prior CI output: systemctl stop exit 5, reset-failed exit 1, seven such lines on a fully green run). Removed; t.Cleanup(stop) alone still covers real end-of-test teardown. - requireRealSystemd's comment claimed mirroring "the same four skip guards" as TestWaitBootedOut_RealLaunchd; it has three, and the darwin test's fourth (launchd refusing to start the test agent at all) has no systemd analog — exactly the asymmetry this file's own header comment already explains. Reworded to match. - The CI step comment attributed all setup-failure catching to ABCTL_SYSTEMD_TESTS=required; that only covers the soft-failure path (session unreachable, so the step warns and the Go test itself Fatalfs). A hard failure (enable-linger itself failing) is instead caught by bash -e failing the step outright, before Test ever runs. Named both paths.

CodeRabbit review, plus a proactive check for the same doc issue already found on #1076: - callLog built its shell redirection with a bare %s path. If TMPDIR contains whitespace or shell metacharacters, the generated fragment is invalid and the fake fails before it ever records its arguments. Use the existing shQuote helper instead of fmt.Sprintf (which is now unused and removed from imports). - Same root cause as #1076's must-fix: this branch's copy of the plan doc claimed the TimeoutStopSec fix (bullet 7) as landed. It isn't — confirmed via `git diff main...this-branch`, which touches none of cmd_service_platform.go's TimeoutStopSec content. That fix lives on sibling PR #1079, not merged yet. Corrected the Status header, bullet 7, Cross-cutting themes 2/3, and Suggested next steps 1 to attribute it there instead of here. Bullet 6 and Cross-cutting theme 1 (the fakeSystemctl/fakeLoginctl harness) are correctly this branch's own contribution and are left as closed.

The PR successfully introduces a fakeSystemctl/fakeLoginctl harness for the Linux service path, closing a significant test coverage gap.
Findings:
- Refactor: Injection of goos into the service functions is clean and follows the pattern established in renderUnitFor. This enables high-fidelity testing of Linux logic on any host.
- Tests: The new cmd_service_systemd_test.go is comprehensive, covering 22 subtests for various systemd/loginctl scenarios (lingering, daemon-reload failures, verb mapping).
- Security: Security gate passed; no changes to .claude/ or .vscode/ configurations.
- DCO: All commits are properly signed-off.
- CI: Noted the Go CI (authlib) failure. Given that this PR only touches cmd/abctl and documentation, and the author notes an unrelated pre-existing failure, this is likely unrelated to the current changes.

All blockers from the previous CHANGES_REQUESTED review are addressed: callLog now uses shQuote to handle paths with shell metacharacters, and the doc Status header correctly attributes the TimeoutStopSec fix to sibling PR #1079 rather than this branch. All CI checks pass. Ready for human review.

…s on #1080 Second round of CodeRabbit findings on #1080, all verified before fixing: - must-fix (x2): bullet 6's header still read "CLOSED (Tier 2) 2026-09-17" even though this PR (#1080) is itself unmerged — a doc announcing its own merge before it happens. Bullet 7's header was already corrected last round, but its body still described TimeoutStopSec as an accomplished, tested fact, which isn't true on this branch. Reworded bullet 6 as "Closing in #1080 (this PR, unmerged)" — true both before and after merge — and bullet 7's body as "In review (#1079)", matching the reviewer's suggested framing exactly. - readCallLog returned nil on ANY read error, not just "file doesn't exist" — so a broken harness (PATH not applied, /bin/sh missing, temp dir gone) would read identically to "genuinely never called", making every negative call-count assertion in this file vacuous. Now distinguishes os.ErrNotExist (real "never called") from any other read error (t.Fatalf, so a harness break is loud). - The linger happy-path tests asserted only the marker file's presence, never the actual loginctl invocation shape. A typo'd verb, the wrong uid, or a bare enable-linger with no argument would each still exit 0 and still write the marker — exactly the wrong-verb bug class this whole harness exists to catch, just not caught here. Added callLog- backed checks on both subtests, plus a new test confirming loadService's happy path calls daemon-reload then enable --now, in that order, with the exact unit name — previously only inferred through failure-path error messages, never checked on a run that succeeds. - Collapsed controlService(goos string, action string, ...) to controlService(goos, action string, ...) per a minor nit; declined the deeper `type goos string` swap-proofing the same comment raised, as it flagged itself as likely out of scope for this PR. 24 subtests now (was 22), all passing.

Re-review at 23eff83. Everything substantive from my last round landed, and I mutation-tested the two new invocation assertions to confirm they're load-bearing rather than decorative.
Fixed since 15:12Z: readCallLog fatals on real read errors · linger happy path asserts enable-linger <uid> · loadService asserts daemon-reload → enable --now ordering · show-user asserted in the skip branch · header and bullets 6/7 reframed to PR numbers · goos, action string collapsed.
Remaining blocker is one stale line in the planning doc that now contradicts a fix made elsewhere in this same PR. The rest is non-blocking.
Local verification: worktree at 23eff83; go test ./cmd/abctl/ -run 'TestSupervisorRunning_Linux|TestLoadService_Linux|TestUnloadService_Linux|TestLingerEnabled|TestControlService_Linux' -v → 27 PASS, 0 FAIL, 0 SKIP. Two mutation probes run (details inline), worktree removed.

Review: #1080 — fakeSystemctl/fakeLoginctl harness for Linux service path
Verdict: APPROVE ✅
Summary
This PR closes the test-coverage gap for the Linux side of abctl service by:
- Refactoring four functions (
loadService,controlService,supervisorRunning,unloadService) to takegoos stringexplicitly instead of readingruntime.GOOSdirectly — the same fixrenderUnitForalready had, now applied consistently. - Adding
cmd_service_systemd_test.go: afakeSystemctl/fakeLoginctlPATH-decoy harness mirroring the existingfakeLaunchctlpattern, with 24 subtests that run on any host by passing"linux"explicitly.
All CI checks pass. All 7 commits are DCO-signed. Author is a MEMBER.
Security gate
No changes under .claude/ or .vscode/. Clear. ✅
Code quality
cmd_service.go / cmd_service_platform.go (production changes): Purely mechanical — 6 call sites updated to pass runtime.GOOS, two function signatures each updated from positional goos string grouping (controlService(goos, action string, ...)). No behavior change; the commit history shows this was done in direct response to a CodeRabbit review request and is a strict improvement over the implicit-GOOS pattern.
cmd_service_systemd_test.go (new file, 394 lines): High quality throughout.
fakeSystemctl/fakeLoginctlmatch thefakeLaunchctldesign exactly — TempDir, os.WriteFile, t.Setenv("PATH") — good consistency.- Argument matching uses
case "$*" in *pattern*)(order-independent), not positional$1/$2matching. This is the right call: the fake won't silently mis-branch if a new flag gets inserted before the subcommand. callLog+readCallLogpattern is a genuine improvement over marker-file-only tests: tests prove what was invoked, not just that something exited 0. The new linger happy-path tests and theloadServiceordering test (daemon-reloadthenenable --now) are particularly valuable — they catch the class of bugs this whole harness is designed for.readCallLogcorrectly distinguishesos.ErrNotExist("genuinely never called") from other read errors (t.Fatalf), so a broken harness is loud rather than vacuously passing.shQuoteused incallLogto shell-quote the log path — correct fix for TMPDIR paths with spaces/metacharacters.- Exit-code comment in
TestSupervisorRunning_Linuxexplains why exit 3 is arbitrary for non-active states (onlyerr != niland stdout content matter). Clear and accurate.
Planning doc (authbridge/docs/superpowers/plans/2026-09-16-linux-install-systemd-945.md): Comprehensive gap analysis. Cross-branch attributions are accurate (bullet 6 = this PR unmerged, bullet 7 = #1079, Tier 3 = #1076). The status header and all PR references are consistent with the commit log.
Minor observations (no changes needed)
- The
servicePathsFixturehelper referenced in the tests is expected to exist in a sibling test file — this compiles fine per CI. lingerMarkerandlingerEnabledare tested here but defined incmd_service_platform.go— correct package (package main), no issue.- The doc references a few items (Tier 3 real-systemd integration,
launchdUsable()-equivalent preflight) that are explicitly scoped to other PRs — appropriate to leave as open items.
What this PR does NOT claim (and shouldn't)
This is correctly scoped to "fake-driver coverage." It doesn't prove real systemctl/loginctl behavior — that's #1076. The planning doc is clear on this distinction.
Clean diff, strong test coverage, consistent with existing patterns. Happy to approve.

Solid, well-scoped refactor. Injecting goos as an explicit parameter mirrors the existing renderUnitFor pattern and correctly unlocks cross-platform test execution — the 22 new subtests cover the scenarios that previously had zero coverage (daemon-reload ordering, linger marker lifecycle, disable --now vs restart verb mapping). No issues found.
All checks pass. Ready for human review.
Reviewed by clawgenti using the github-pr-review skill
Third round of CodeRabbit findings on #1080, verified before fixing: - must-fix: my prior fix (readCallLog distinguishing ErrNotExist from other errors) only closed one of two ways a broken harness reads as "correctly never called." Reproduced the surviving one myself first: flip a stub's permissions from 0o700 to 0o600 (present, not executable) and "no_marker: loginctl is never called" PASSES while "marker_present: disable-linger runs" FAILS — same green/red contradiction, reached a different way. A non-executable (or otherwise unreachable) stub means the code under test's own exec.LookPath/exec.Command fails before touching the stub, so nothing is ever appended to the log — indistinguishable from a genuine zero-calls outcome. Moved the fix into the shared installer instead of the assertion layer: fakeSystemctl and fakeLoginctl now both go through a new installStub helper that immediately confirms, via exec.LookPath, that the binary it just wrote is actually reachable — failing loudly once, for every subtest that uses either helper, rather than leaving each call-log assertion to rediscover the gap independently. Reproduced the fix working in both directions: the same mutation now fails loudly across the board, and all 27 subtests still pass unmutated. - Stale count: doc said "22 subtests, all passing" (already stale before this round — the three table-driven loops contribute more subtests than a flat count implies); actual count verified by running with -v is 27. Corrected. - Suggested next steps item 2 still carried a fabricated "done 2026-09-17" date (this branch's first commit is 2026-09-21) and contradicted bullet 6's already-correct "unmerged" framing just above it. Dropped the date, kept the PR number, matching the reframing already applied elsewhere in the file. - Cross-cutting theme 2 and bullet 6's "Still open" note both still read as if Tier 3 (the real-systemd integration test) were unbuilt or vaguely "addressed" rather than citing where — #1076 — matching the terse citation style used elsewhere in the doc.

Verdict: Approve
Clean, well-motivated refactor with thorough test coverage. All CI passes; DCO signed on all 8 commits.
What this PR does well
Core refactor — The goos string parameter is threaded consistently through all four functions (loadService, controlService, supervisorRunning, unloadService) and all 6 call sites in cmd_service.go. This mirrors the pattern already applied to renderUnitFor and closes the same testability gap on the Linux side.
Test harness design — installStub's exec.LookPath confirmation after writing the stub is the right fix for the vacuous-pass problem. Moving the check to the installer rather than individual call-log assertions ensures every subtest that uses either helper gets the protection, not just the ones you happened to add assertions to. The mutation-tested proof (flip perms to 0o600 → correct failure) is the kind of evidence that earns confidence.
readCallLog error handling — Distinguishing os.ErrNotExist (genuinely never called) from any other read error (t.Fatalf) is the correct semantics. A harness failure that reads as "correctly zero calls" is exactly the class of silent false-pass that makes test suites untrustworthy.
callLog path quoting — Using shQuote for the redirect target is correct and preemptive; a bare %s path in the heredoc would silently break in any TMPDIR with spaces or metacharacters.
Argument matching — Switching from positional $2/$1 to case "$*" in *pattern*) is the right long-term robustness choice. Position-sensitive stubs are a maintenance trap when callers grow new flags.
Doc accuracy — The planning doc correctly attributes what's closed by this PR, what's still open in #1079 and #1076, and uses the terse "In review (#NNNN)" framing consistently. No overclaiming.
Minor observations (no action required)
TestLingerEnabledcovers the "malformed output reads as already-on" and "loginctl fails reads as already-on" error-safe behavior with explicit table-driven cases — good defensive documentation.- The comment on
fakeLoginctl's separate temp dir ("each dir holds only its own stub, so there's nothing for the two to collide over") saves the next reader from a real head-scratcher. - 27 subtests confirmed passing (the doc's earlier "22" was stale from before the
readCallLogfix and the three new happy-path call-log assertions expanded the count).
LGTM.
…g on #1076 Fourth round of CodeRabbit findings, all verified before fixing: - must-fix: bullets 6/7's bodies still said "Fixed:" for work living entirely on #1079/#1080 (both open, unmerged), and theme 1 was struck through as if #1080's half had landed too. Changed both labels to "#1080 (open):" / "#1079 (open):", matching the terse citation style already applied elsewhere; un-struck theme 1 and reworded it to attribute the real-systemd half to this branch and the fake-harness half to #1080 specifically, rather than claiming both landed. - Bullet 6's "Still open" note said Tier 3 (real-systemd integration test) was "still not built" — contradicting bullet 5 immediately above it, which is this branch's own accomplishment. Pointed at bullet 5 instead of repeating the stale claim. - The cleanup t.Logf added two rounds ago still produced noisy "cleanup:" lines on every normal passing run — confirmed from this PR's own CI output (run 35750943568): systemd-run transient units are garbage-collected once inactive, so by teardown time `stop` on an already-gone unit exits 5, and `reset-failed` on one that's neither failed nor loaded exits 1 — both routine, not a leak. Added isExitCode and filter exactly those two known-benign codes, so only a genuinely unexpected cleanup failure gets logged. - Documented an untracked gap surfaced while building this PR: ABCTL_LAUNCHD_TESTS=required is never set by any workflow, so TestWaitBootedOut_RealLaunchd still skips in every CI run — the exact trap this PR exists to avoid on the Linux side, left open on the macOS one. No macOS runner exists here to close it, so noted against #944/#956 in "Relationship to other issues" rather than left to be rediscovered.

All checks pass. Ready for human review.

The combined plan doc was copied identically across three
independently-reviewed branches and tried to track all three PRs'
live merge status via prose ("CLOSED", "Fixed:", "sibling PR #X
(open)"). That drifted every time any of the three changed, which is
exactly what produced round after round of "must-fix: this claims
work that hasn't landed" review comments.
None of the other docs in authbridge/docs/superpowers/ do this.
Checked all nine: they track status via task checkboxes scoped to one
document/one branch/one eventual PR (main-channel.md's last section
is literally "Task 7: ... and PR", singular), and reference the
parent issue number in the header rather than tracking sibling PRs'
merge state inline. Multi-PR work gets separate documents
(pricing-consolidation-core.md / -phase0.md), not one document
describing several.
Split accordingly:
- specs/2026-09-16-linux-systemd-lifecycle-design.md: the frozen
research (systemd/launchd background, the full gap analysis as
originally found) — timeless, makes no claims about which PR fixes
what, so it can't go stale the way the old doc did.
- plans/2026-09-21-systemd-real-integration-test.md: a small,
self-contained task list for this branch's own work only, no
reference to #1079/#1080's status at all.
Deletes the old combined doc.

Same restructuring as the sibling commit on #1076, and same reason: this repo's other planning docs track status via task checkboxes scoped to one document/one branch/one PR, and reference the parent issue number rather than tracking sibling PRs' merge state inline. Multi-PR work gets separate documents, not one shared doc trying to describe several — which is exactly what kept going stale here. - specs/2026-09-16-linux-systemd-lifecycle-design.md: identical copy of the frozen research doc added on #1076 — safe to duplicate because it makes no claims about which PR fixes what, so it can't drift the way the old doc did. - plans/2026-09-21-systemd-fake-harness.md: a small, self-contained task list for this branch's own work only (the goos refactor + the fakeSystemctl/fakeLoginctl harness), no reference to #1079's or #1076's status. Deletes the old combined doc. Assisted-By: Claude (Anthropic AI) <noreply@anthropic.com> Signed-off-by: Alan Cha <Alan.cha1@ibm.com>

Solid refactor — extracting goos as an explicit parameter mirrors the existing renderUnitFor fix and makes the 22-subtest harness possible on any host. One minor nit on the call-log approach below.
Findings:
readCallLogtreats a missing file as "never called" (correct), but any other read error callst.Fatalf— which is good, and the plan doc notes this fix explicitly. Worth confirming thefakeSystemctl/fakeLoginctlinstallStub-style reachability check is there so a broken harness (stub not executable) can't silently masquerade as "zero calls."

supervisorName still read runtime.GOOS directly, one call deep inside
loadService — the one function this PR's refactor made accept goos
explicitly. Dormant today since every new test only drives "linux",
but it would have silently produced the wrong supervisor name in any
error message if loadService("darwin", ...) were ever exercised from
a non-darwin host, which is exactly the capability this refactor
exists to enable.
Also fixes the shared spec doc's stale main.go line reference for the
15s shutdown timeout (was pointing at unrelated mTLS setup code) and
softens an inaccurate "undocumented" claim about systemd's
DefaultTimeoutStopSec, which is documented in systemd.system.conf(5).

Solid test-infrastructure PR that closes a real gap in Linux service-lifecycle coverage. The goos refactor is consistent with the existing renderUnitFor pattern, all 6 call sites in cmd_service.go are updated, and the installStub reachability check correctly closes the vacuous-pass hole (broken harness ≡ genuine zero-calls).
All checks pass. Ready for human review.

The refactor is correct and the test file is genuinely strong. I audited all 13 call sites of the five refactored functions — every one passes runtime.GOOS, none stale — and ran the new tests on a detached worktree at 07cce6fe: 27 subtests, all PASS, all genuinely executed on darwin, which matches the plan doc's Result claim exactly. gofmt -l and go vet clean. I also reproduced your vacuous-pass experiment by flipping the stub mode to 0o400, and installStub does fail loudly (stub not reachable: LookPath("loginctl") = "") — that check earns its comment.
One must-fix, and it's a timing regression rather than an edit: #1079 merged at 2026-09-22T16:43:58Z, about 2.5 hours before this branch's last push, so spec §7 now asserts a gap that is closed in the tree this doc is landing in. Root cause for both doc findings is that the branch sits 274 commits behind main — the line-number citations were written against a much older tree.
The rest is advisory: one reuse finding (the launchd half of the harness never got the reachability check this PR argues for), and two nits on the new test file.

- Cite main.go's shutdown timeout by symbol, not line number, in the spec doc — same fix as the sibling PR, same reason: main.go isn't part of either PR's diff and keeps moving as unrelated PRs merge. - Record #1079's TimeoutStopSec=20 as closing gap 7, now that it has merged. - Clarify the #966 reference: that issue is closed, and its allow-legacy-plugin-tag exemption matches the whole file, not just the one mention. - Narrow the plan doc's "closing checklist bullet 6 of #945" claim: this PR closes the unit-test half only. The spec's real-systemd integration-test half and the serviceStatus/serviceControl-accuracy half are untouched here. - fakeLaunchctl now delegates to installStub instead of hand-copying its body without the exec.LookPath reachability check: the vacuous-pass hole installStub closed for fakeSystemctl/fakeLoginctl was still open on the launchd side, in the very file this harness is modelled on. - Document that noSystemctlOnPath replaces PATH rather than prepending to it, so it must never run after fakeSystemctl/fakeLoginctl in the same subtest. - Thread callLog through "daemon-reload failure is reported, enable is never attempted" so the never-called claim is a literal check against the call log, matching every other never-called assertion in this file, rather than something inferred from the error message format.

Refactors supervisorName, loadService, controlService, supervisorRunning, and unloadService to accept an explicit goos string parameter (mirroring the existing renderUnitFor pattern), then adds a full fakeSystemctl/fakeLoginctl/installStub PATH-decoy harness with 22 subtests covering daemon-reload/enable failures, linger lifecycle, and verb-per-action mapping — all runnable on any host OS. All checks pass. Ready for human review.

Review: #1080 — fakeSystemctl/fakeLoginctl harness for the Linux service path
Verdict: APPROVE ✅
Author: Alan Cha (MEMBER) | CI: All checks pass | DCO: All 12 commits signed off
Summary
This PR closes a real test-coverage gap: loadService, controlService, supervisorRunning, and unloadService all took runtime.GOOS directly, meaning none of their Linux logic could be exercised from a non-Linux host. The fix — refactoring all four to accept goos string explicitly — mirrors the pattern already applied to renderUnitFor, and the 427-line test file that follows it is a thorough, disciplined harness.
What's Good
The installStub reachability check is the right fix for the right problem. The PR correctly identifies that a broken harness (stub not executable, PATH not applied) reads identically to "genuinely never called" in a call-log absence check, and closes it at the installation site rather than scattering it across individual assertions. The mutation-proof verification story in the commit messages is particularly thorough.
Call-log based assertions are well-scoped. Tests like TestLoadService_Linux/daemon-reload_then_enable_--now,_in_that_order and TestControlService_Linux's verb-per-action table drive both the positive shape (--user daemon-reload then --user enable --now cortex.service) and the negative bounds (exactly N calls, nothing extra). This is exactly the kind of coverage that catches a reordered argument or a mistyped verb.
readCallLog distinguishing ErrNotExist from other errors is a small but important detail — a harness that silently absorbs read errors would defeat the entire purpose of the call log.
noSystemctlOnPath usage note is explicitly documented. The comment warning that it replaces rather than prepends PATH, and therefore must never run after fakeSystemctl/fakeLoginctl in the same subtest, is exactly the kind of footgun documentation that prevents a future contributor from causing a silent vacuous-pass.
fakeLaunchctl delegating to installStub closes the same hole on the macOS side — good catch that the very file this harness was modeled on had the same gap.
shQuote used for the call-log path. Using the existing helper for the shell redirect target rather than a bare %s path is correct and consistent. The comment clarifying that shQuote's doc describes it in a systemd-ExecStart context but the escaping rule is plain POSIX sh is a useful note for readers who might otherwise hesitate.
Doc restructuring (separate spec + per-PR plan doc, matching the repo's existing convention) directly eliminates the stale-cross-PR-status class of problem that the earlier shared doc kept experiencing.
Nits / Suggestions (non-blocking)
servicePathsFixture is referenced but not defined in the diff. It presumably exists in cmd_service_test.go already — confirming this is fine, but if it's new to this PR it should appear in the diff. (This reads as a pre-existing helper, not a gap.)
27 subtests noted in the plan doc — the table-driven loops (TestSupervisorRunning_Linux iterates 4 states, TestControlService_Linux iterates 3 actions) mean the count isn't obvious from a flat scan, but the doc explains this clearly.
Security Gate
No .claude/ or .vscode/ changes. Author is MEMBER. No new shell exec of user-controlled input.
This is a clean, well-motivated PR with a strong test harness and careful attention to failure modes. The iterative CodeRabbit review integration is visible in the commit history and the final quality is high. Happy to approve.

Refactor is clean and the new harness is thorough — threading goos through loadService, controlService, supervisorRunning, and unloadService is the right pattern and mirrors the existing renderUnitFor treatment. The installStub reachability gate is a particularly good catch, closing the vacuous-pass hole on both the systemctl/loginctl and launchctl sides.
All checks pass. Ready for human review.

The goos refactor is clean and complete — all 11 call sites in cmd_service.go updated, no behavior change, and the four Linux branches now genuinely run on any host rather than being dead code off-Linux. I read those Linux branches on the head tree rather than trusting the test names, and the call-shape assertions match what the code actually invokes; the installStub/readCallLog pair does close the vacuous-pass hole it claims to. Spot-checked all four line-number citations in the spec doc (platform.go:92-93, cmd_service_test.go:312, platform.go:680, install.sh:645) and they all still land.
Two counting/wording drifts worth a pass. The PR body says "22 subtests" in both the description and the test plan, but the actual count is 27 — 19 t.Run literals, minus 3 loop headers, plus 4 is-active states, 3 control verbs, and 4 lingerEnabled cases. The plan doc's "27" is the correct one, so it's the body that's stale. And the #1079 sentence in the spec doc went stale between writing and pushing (comment inline).
Nothing blocking. Three suggestions and two nits inline.

suggestion — This is the one invocation in the file whose shape isn't pinned on the failure path. Contains(err.Error(), "disable") stays green even if the unit name were wrong, and no unloadService subtest call-logs systemctl at all — so a typo'd unit in unloadService's disable --now is the single thing this harness can't catch, in a PR whose whole point is catching exactly that.
TestControlService_Linux's sibling assertion already pins the full string:
!strings.Contains(err.Error(), "--user disable --now cortex.service")Copying that here is a one-line fix and makes unloadService symmetric with the other three.

There was a problem hiding this comment.
suggestion — show-user is the only call in this file whose arguments are never pinned anywhere. lingerEnabled("501") never inspects what the fake received, so a wrong property flag (--property=Lingering) or a wrong uid would leave all four cases green: the parsing is genuinely covered, the invocation isn't. Lines 246 and 276 don't close it either — both only strings.Contains(calls[0], "show-user"), never --property=Linger or the uid.
Threading callLog through one of these cases and asserting show-user <uid> --property=Linger would finish the job the rest of the file already does.
Separately, "501" is a macOS-shaped uid literal in a Linux-only test — strconv.Itoa(os.Getuid()) reads truer and matches what line 275 already does.

suggestion — Worth noting for the next increment rather than this PR: serviceIsCurrent now passes runtime.GOOS down (here) but still branches on it itself two lines up (runtime.GOOS == "darwin" && !strings.Contains(body, "--supervise")), as does reportInstallSuccess at line 498. So both remain host-locked for precisely the reason the four functions below were — their darwin-only logic can't be exercised from a Linux host, and vice versa.
Clearly out of scope here; the PR body and plan doc both scope to the four. Just flagging that the same refactor has an obvious second half.

nit — echo "$@" on a zero-argument invocation appends a blank line, and readCallLog filters empty lines out (line 93), so such a call would read as "never called" to every count assertion in this file. That's the same shape of hole installStub's reachability check exists to close — a broken/invisible call indistinguishable from a correct zero-calls outcome.
Latent only: every real call site here passes arguments, so nothing reaches it today. echo "argv: $@" (or any non-empty prefix) makes it observable if that ever changes.

nit — "Not yet on this branch's own tree until it merges" reads as "#1079 hasn't merged yet," but it merged 2026-09-22 16:43 UTC — roughly three hours before this sentence was pushed. I confirmed both halves: this branch head still has no TimeoutStopSec, and main has it at cmd_service_platform.go:150.
So the first half of the paragraph is accurate and the second half inverts. The accurate framing is that it's already on main, and this branch is simply behind and picks it up on the next rebase.
