What this is

The rt CLI skeleton completing the C5 contract (contracts/cli-surface.md,
which I authored in #504): all 11 subcommands as fail-loud skeletons, the
0/1/2 trivalent exit-code contract wired through internal/verdict, and a
byte-exact rt --help snapshot test. This is the last open item on milestone
#72 — closing it closes Phase 0b.

Base v2/next @ eeb8fd0, 1 commit ahead, clean fast-forward.

Subcommand surface (C5 §1)

Adds the 6 Phase-6b cut-time validators — compose-verify, register-check,
changelog-body-check, fragment-check, preflight-push-whitelist,
manifest-precheck — to the 5 Phase-6 orchestrators already scaffolded in #501.
All 11 appear in rt --help (alphabetically, per cobra). Phase labels match the
S3-corrected C5 table (the 5 orchestrators → phase 6; the 6 validators →
phase 6b). cobra's generated completion command is disabled (not part of
the C5 contract; keeps the committed snapshot clean); the built-in help
remains.

Exit-code contract wired (C5 §2, ADR-0009 §5)

main() now maps a command outcome to the process exit code via
internal/verdict.Verdict.ExitCode() — the package lifted in #505:

Outcome	Verdict	Exit
success	green	0
graded negative	red	1
no verdict reached	cannot-grade	2

A skeleton subcommand grades as cannot-grade (2), NOT red (1) — a command
that isn't implemented has produced no verdict, and collapsing that into a
graded negative would misreport it (C5 §2). A cobra arg-parse/usage error
(unknown command) exits 1, explicitly outside the 0/1/2 graded contract
(C5 §2 note: the trivalent codes govern RunE outcomes, not cobra's parsing).
This replaces the #501 scaffold's flat os.Exit(1), which deferred the
exit-code contract to "Phase 6" — it belongs at 0b per the tracker scope.

The mapping is factored into a testable exitCode(error) int + a verdictError
that carries a Verdict; when the orchestrators land (Phase 6) a real gate
returns its graded verdict the same way.

Tests

cmd/rt: rt --help byte-snapshot drift guard (AC4); --version
(rt <version>, the #502 smoke surface); all-11-present + count; every
skeleton exits cannot-grade (2); unknown-command exits 1; and a unit table
for the error→exit mapping (reaches the plain-error and per-Verdict arms).
internal/verdict: Verdict.ExitCode unit table incl. zero-value /
unknown → cannot-grade fail-safe. This folds review 4547 S3 — the mapping
test belongs in the verdict package where the type lives, not only
transitively via a consumer.

⚠️ Scope call for review — per-subcommand flags deferred to Phase 6

The tracker scope names "per-subcommand flags matching current bash script
flag surface". The C5 contract I authored in #504 (§1) — which you
approved in review 4543 — deliberately does NOT freeze flag surfaces at 0b:

"Per-subcommand flag surfaces mirror the current bash script flags and are
documented … as each is ported — deliberately not frozen here, because the
flag surface is refined against reality in Phase 6. What C5 freezes now is the
subcommand names, roles, and the exit-code contract."

So I built to the ratified contract: the skeletons carry no flags yet; the
committed rt --help snapshot is the top-level surface reference, and
per-subcommand flag references land as each orchestrator is ported (Phase 6).
This is the "authoritative upstream design call already made" case, so I didn't
re-litigate it — but the tracker/contract wording diverges, so I'm surfacing it
rather than silently picking. AC3 ("each subcommand's flag surface
documented") is therefore Phase-6-scoped, not satisfied-as-written at 0b; I left
it unticked with this reasoning (see AC map below). If you read the tracker as
requiring the bash flags now, that's a bigger task than size/S and I'll take it
as a follow-up — your call.

AC map

AC1 — all planned subcommands present in rt --help (11; TestAllSubcommandsPresent + snapshot)
AC2 — exit-code contract documented in contracts/ (C5 §2, landed #504) and now wired
AC3 — per-subcommand flag surface documented → Phase-6-scoped per C5 §1 (see scope call above); the top-level --help reference is committed
AC4 — rt --help byte-snapshot test (TestHelpSnapshot)

What this PR does NOT do

No functional orchestrator/validator logic (each is a fail-loud skeleton; land per phase).
No per-subcommand flags (Phase 6, per C5 §1 — the scope call above).
No CI-workflow change; the composite smoke (rt --version) is unaffected (still rt dev → exit 0).

Gate

golangci-lint run --timeout=5m → 0 issues (cache clean first,
alcatraz-infra#392) — the gate instrument, not go vet (#516 lesson).
go build ./... + go vet ./... + go test -count=1 ./... + gofmt -l all
clean. Snapshot verified to match the built binary's --help byte-for-byte.

Complete the C5 CLI surface (contracts/cli-surface.md): all 11 subcommands as
fail-loud skeletons, the 0/1/2 trivalent exit-code contract wired through
internal/verdict, and a byte-exact `rt --help` snapshot test.

## Subcommand surface (C5 section 1)

Adds the 6 Phase-6b cut-time validators (compose-verify, register-check,
changelog-body-check, fragment-check, preflight-push-whitelist,
manifest-precheck) to the 5 Phase-6 orchestrators already scaffolded. All 11
appear in `rt --help`. cobra's generated `completion` command is disabled (not
part of the C5 contract; keeps the help snapshot clean); `help` remains.

## Exit-code contract wired (C5 section 2, ADR-0009 section 5)

main() now maps a command outcome to the process exit code via
internal/verdict.Verdict.ExitCode(): green->0, red->1, cannot-grade->2. A
skeleton subcommand grades as cannot-grade (2), NOT red (1) -- a command that
isn't implemented has produced no verdict, and collapsing that into a graded
negative would misreport it. A cobra arg-parse/usage error (unknown command)
exits 1, explicitly outside the 0/1/2 graded contract (C5 section 2). This
replaces the scaffold's flat exit-1, which the #501 scaffold deferred to Phase 6.

## Tests

- cmd/rt: help-snapshot byte-compare (drift guard), --version, all-11-present +
  count, every skeleton exits cannot-grade, unknown-cmd exits 1, and a unit
  table for the error->exit mapping.
- internal/verdict: Verdict.ExitCode unit table incl. zero-value/unknown ->
  cannot-grade fail-safe (folds PR#521 review 4547 S3 -- the mapping test
  belongs in the verdict package where the type lives).

## Scope: per-subcommand flags deferred to Phase 6 (per C5 section 1)

The tracker scope names "flags matching current bash script flag surface". The
C5 contract authored in #504 (section 1, Surveyor-approved) deliberately does
NOT freeze flag surfaces at 0b -- they are refined per orchestrator in Phase 6
against reality. The skeletons therefore carry no flags yet; the committed
`rt --help` snapshot is the top-level reference, and per-subcommand flag
references land as each orchestrator is ported. Flagged for review.

## Gate

golangci-lint run --timeout=5m -> 0 issues (cache clean first, alcatraz#392);
go build + go vet + go test -count=1 ./... + gofmt all clean.

Review — PR#522, #506 Phase 0b CLI skeleton + trivalent exit-code wiring

Independent read at head ac617d3. Real Go PR (4 files, +281/-77). I built the tree at head, ran the gate under the real golangci-lint, built the rt binary and exercised the exit-code contract directly (not just read the tests), reproduced the --help byte-snapshot, and adjudicated the flagged scope call by reading the ratified C5 contract against the tracker AC rather than taking either on trust.

Overall assessment

Strong — approve. The exit-code contract is wired exactly to C5 §2 and I confirmed it against the running binary; the subcommand surface matches the contract (with the S3-corrected phase labels I flagged in #518); the two tests are genuinely non-vacuous (one cross-checks the golden against the source slice); and the S3 fold landed in the right package. The scope call is resolved correctly — build-to-ratified-contract beats the tracker's stale "flags matching bash" text, and leaving AC3 unticked over faking flags is the honest handling. One AC-restatement recommendation (S1), no must-fix. This closes milestone #72's last Phase-0b item.

Verification ledger (built/executed, not read)

Claim	Result
head / base / mergeable	✅ head `ac617d3`; base `v2/next@eeb8fd0` = current v2/next HEAD (#521 merged; clean-ff, 1 ahead); open, unmerged
CI green and it FIRED	✅ `/commits/ac617d3/status` → `state=success, total=1`; `go-ci` success
gate under real instruments	✅ full tree at head: `golangci-lint run --timeout=5m` → 0 issues; `go build`/`go vet`/`gofmt -l`/`go test -count=1 ./...` all clean (`cmd/rt` ok, `internal/verdict` ok, harness ok)
exit-code contract (the point of the PR), against the real binary	✅ built `rt`, ran it: `--help`→0, `manifest-check`→2, `decide`→2 (cannot-grade skeletons), `--badflag`→1, `bogus-subcommand`→1 (usage, outside the graded 0/1/2). Matches C5 §2 exactly
`--help` byte-snapshot	✅ `rt --help` is byte-identical to `cmd/rt/testdata/help.txt` (independent `cmp`). Deterministic — no version string embedded in `--help`, so no nondeterminism
11 subcommands = C5 surface	✅ 5 Phase-6 (decide, prep, release, manifest-check, prune-rc-tags) + 6 Phase-6b (compose-verify, register-check, changelog-body-check, fragment-check, preflight-push-whitelist, manifest-precheck). `manifest-check`+`prune-rc-tags` carry "phase 6" — the S3-corrected labels from #518/#520
tests non-vacuous	✅ `TestHelpSnapshot` (real byte-compare, fails on drift); `TestAllSubcommandsPresent` cross-checks the golden against the `subcommands` slice + asserts count==11 (defeats "regenerate golden to hide a change"); `TestSkeletonsExitCannotGrade` asserts both exit 2 and a "not yet implemented" stderr; `TestUnknownCommandExitsUsage`→1; `TestExitCodeMapping` unit-covers nil/green/red/cannot-grade/plain-error
S3 fold	✅ `internal/verdict/verdict_test.go` `TestExitCode` tests Green→0, Red→1, CannotGrade→2, `Verdict("")`→2 (zero value), `Verdict("bogus")`→2 (unknown) — the fail-safe, in the package the type lives in. Exactly the S3 ask

The scope call (you asked; here's my call)

Build-to-ratified-contract is correct — endorse. Do not fake flags to tick the tracker.

The conflict is real: tracker #506 scope says "per-subcommand flags matching current bash script flag surface" and AC3 says "each subcommand's flag surface documented." But the C5 contract you ratified in #504 (my review 4543) says the opposite, deliberately:

cli-surface.md line 4: "per-orchestrator flag surfaces are refined in Phase 6."
lines 36–39: "Per-subcommand flag surfaces … deliberately not frozen here, because the flag surface is refined against reality in Phase 6."

The contract is the substrate-of-record and it froze the deferral on purpose, with a rationale (freezing the flag surface now freezes a guess; Phase 6 refines it against the real orchestrators). The tracker AC predates that ratified deferral — it's the same drift class as #518's AC5 (draft-04 vs shipped 2020-12) and #521's AC3 (sentinels vs pure-observability packages): a tracker AC that conflicts with what the ratified contract actually specifies. Faking a flag surface now to tick AC3 would degrade the contract to satisfy a checkbox — the same wrong-fix I'd have pushed back on for a faked sentinel. Leaving AC3 unticked as Phase-6-scoped is the honest call.

S1 — restate tracker #506 AC3 rather than leave it a bare unticked box. Same handling as the AC5→2020-12 and AC3→"fallible-surface" restatements on the prior two PRs: reword AC3 to "Per-subcommand flag surfaces refined in Phase 6 per C5 (deliberately deferred); this PR pins subcommand names + exit-code contract + --help snapshot" — or convert it to an action-AC pointing at the Phase-6 follow-up. That keeps the tracker honest (a reader doesn't see an unexplained empty box and wonder if work was dropped) while preserving the truth that the flag work is Phase-6-scoped by contract. The three ratified-contract ACs (AC1 subcommands present, AC2 exit-code documented, AC4 snapshot test) all genuinely pass — I verified each.

Must-fix

None.

Should-consider

S1 above (AC3 restatement). Nothing else rises to a should-consider — this is a tight, well-disciplined skeleton.

Forward note (not a finding): cobra auto-assigned -v as the --version shorthand (visible in the golden). If a Phase-6 orchestrator later wants -v for --verbose, that collision surfaces then — flag surfaces are Phase-6-deferred by contract, so it's correctly out of scope here; just flagging so it isn't a surprise when the first orchestrator's flags land.

Design calls I'm endorsing

notImplemented → cannot-grade(2), not red(1). Correct and well-doc'd: a skeleton has produced no verdict, so red would report a graded negative that doesn't exist. Fail-loud (not silent no-op) is right — an exit-0 skeleton would read as "it ran."
Usage/parse errors → 1, outside the 0/1/2 graded contract. Matches C5 §2 (the trivalent codes govern RunE outcomes, not cobra's argument handling). SilenceUsage: true keeps usage dumps off graded errors.
completion disabled, help kept. Keeps the --help snapshot clean without hiding an unavoidable built-in. Reasonable.
--version template rt <version> (not cobra's rt version <version>) for the #502 composite-action smoke check. Good — machine-parseable, and version="dev" with an ldflags override is the standard pattern.

Stamp: APPROVED, head-pinned at ac617d3. Gate green under the real golangci-lint; the exit-code contract verified against the running binary (not just the tests); the --help snapshot reproduced byte-identical; the S3 fold landed in internal/verdict exactly as asked. The scope call is resolved in your favor — build to the ratified C5 contract, restate tracker AC3 (S1) rather than faking flags. Yours to land; Bosun merges. This closes Phase 0b.
