Port scripts/preflight-push-whitelist.sh (143 LOC) to rt preflight-push-whitelist subcommand. Phase 6b validator/gate per ADR-0009 §3.3.

Scope (updated 2026-07-27 per Engineer framing-verify bus 94c4)

Preflight validator for path-alpha cuts:

Resolution sequence: mode-gamma→skip; owner/repo via prepkg.OwnerRepoFromURL; GetDefaultBranch; GetAuthenticatedUser; GetBranchProtection
Pure decision (in gates): whitelist-off→pass; identity-in-usernames→pass; teams>0→warn; else→fail
Fail-safe: any resolution failure → warn+proceed (exit 0)
4-STATE verdict (skip / pass / warn / fail): exit 0 on skip/pass/warn; exit 1 only on definitive fail. NOT trivalent (warn is exit 0, not cannot-grade/2)
Live-API consumer (first in Phase 6b — others are content-scanners or git+file)
NOT a Cutter consumer; forgejo.Client accretion = ZERO

AC

rt preflight-push-whitelist compiles + all preflight logic ports byte-faithful to preflight-push-whitelist.sh
4-state verdict preserved: exit 0 on skip/pass/warn; exit 1 only on definitive fail
Fail-safe: any resolution failure → warn+proceed (matches bash oracle)
Pure decision in internal/gates.PreflightPushWhitelist(bp, identity); resolution sequence in cmd/rt
Leak-guard port: FORGEJO_TOKEN sentinel MUST NOT appear anywhere in preflight output surface (preserves #94/#260 regression class-guard)
Coverage split (F3 Option A): 2 non-API cases (gamma-skip, no-remote-warn) via equivalence harness; API-path via unit tests with injected fake Client + bash bats; 11-case full harness disclosed-deferred
go vet ./... + golangci-lint run clean

Framing-verify ratification notes (2026-07-27, bus 94c4)

Engineer's framing-verify surfaced a FAVORABLE substrate finding + 5 ratifiable forks.

Favorable-substrate anchor: forgejo.Client accretion=ZERO for #570. All 3 reads needed (GetDefaultBranch + GetAuthenticatedUser + GetBranchProtection) + the BranchProtection struct (EnablePushWhitelist/PushWhitelistUsernames/PushWhitelistTeams) ALREADY EXIST from Phase 4, built SPECIFICALLY for this consumer per BranchProtection's own doc comment ("NOT .enable_push"). Substrate was forward-designed for the consumer.

Bidirectional-correction-cycle pattern named: Phase-6b framing-verify surfaces run in both directions:

Unfavorable-correction (instance 1 example — #571 primitives inventory): my "thin wrapper over CheckDesyncVerbose" was WRONG; zero overlap
Favorable-substrate (instance 2 example — #570): forgejo.Client accretion=ZERO; substrate more ready than a naive read suggests

Both directions are substrate-honest; both need Engineer's framing-verify pass to reach honesty. Anchor for future Phase-6b framing-verifies: not all corrections are downward; some surface confirmations of forward-looking substrate design.

F1 — 4-STATE verdict shape (RATIFIED)

preflight = skip | pass | warn | fail. Exit 0 on skip/pass/warn; exit 1 ONLY on definitive fail. Same class-shape as #571 F3 (per-gate verdict shape) but 4-valued. internal/verdict does NOT apply. n=2 of milestone-language-generalization correction pattern in Phase 6b — milestone §5's "trivalent at wire boundary" is general framing, not this gate's contract. Filed as substrate-of-record.

F2 — Placement split (RATIFIED)

Pure gates.PreflightPushWhitelist(bp, identity) core (whitelist-off→pass; identity-in-usernames→pass; teams>0→warn; else→fail) + cmd/rt owns the resolution sequence (mode-gamma→skip; owner/repo via prepkg.OwnerRepoFromURL; GetDefaultBranch; GetAuthenticatedUser; GetBranchProtection). Every resolution failure → warn+proceed (fail-safe). Clean separation matches #571's philosophy + #559's cmd-vs-lib boundary.

F3 — Coverage split (RATIFIED — Option A)

Rejected Option B: honor the 4 FORGEJO_TEST_* seams in Go PROD for a full 11-case harness. Rationale for rejection:

Adds bash-test-plumbing to prod API client (contamination of substrate scope — scope-at-point-of-use failure mode)
Needs read-dry-run-awareness (extends Client API surface for test-only concern)
Worse coupling than #571's single MANIFEST_REMOTE_FIXTURE

Ratified Option A (#559 precedent):

Pure decision + resolution branches → unit tests with injected fake Client
Existing bats = bash byte-oracle
Minimal equivalence harness for 2 cleanly-non-API cases (gamma-skip, no-remote-warn)
API-path equivalence disclosed-deferred (canned-both-sides high-cost; the 3 reads carry their own equivalence in internal/forgejo at their layer)

Coverage split disclosure at design time — pre-emptive discipline shape same as #555 F5.

F4 — No events to retire (RATIFIED — not applicable)

#570 sources forgejo-api.sh, not events.sh. log() → stderr uncompared. Only preflight=X on stdout compared. Substrate-honest — not applicable rather than perform-not-applicable retirement.

F5 — Leak-guard port (RATIFIED)

Assert FORGEJO_TOKEN sentinel appears NOWHERE in preflight output surface. Token lives only in Client auth header; fail path is densest log surface. Preserves #94/#260 regression class-guard.

Refinement accounting

Cutter refinement count: STAYS FIRM at 3/5. #570 contributes 0.
forgejo.Client refinement count: STAYS at 3 (Author + Labels + ListPRs from #555 arc). #570 adds ZERO — substrate was forward-designed.
internal/gates substrate: gains PreflightPushWhitelist alongside existing siblings. Additive.

Milestone #79
Sibling Phase 6b validators: #567, #568, #569, #571, #572

CLOSED via PR#575 merged @4786549 (2026-07-27 12:45 CEST, rebase-merge, HTTP 200, gate 4/4 byte-verified pre-fire).

ACs re-derived from merged substrate + Surveyor's independent deep-verify (bus 8cdc), applying "name the coverage surface" discipline:

rt preflight-push-whitelist compiles + all preflight logic ports byte-faithful — surface: full-gate green host + forgejo-ci-go:latest; Surveyor's bash-vs-rt against oracle confirms
4-state verdict preserved (skip/pass/warn/fail with correct exit codes) — surface: byte-oracle covers verdict via bats, 9/11 harness cases; 404/200 warn-vs-pass split verified through internal/forgejo (getObject: 404→ErrNotFound→Warn, decoded 200→pure fn)
Fail-safe: any resolution failure → warn+proceed — surface: gamma skip→pass mutation reds exactly the equiv gamma-skip; matches bash oracle
Pure decision in internal/gates.PreflightPushWhitelist + resolution in cmd/rt — surface: F2 placement split honored; Surveyor verified cmd-vs-lib boundary
Leak-guard port: FORGEJO_TOKEN sentinel MUST NOT appear in output surface — surface: Surveyor mutation-confirmed non-vacuous on BOTH axes (token-sent + not-logged); #94/#260 regression class-guard preserved
Coverage split F3 Option A: 2 non-API cases via equivalence harness; API-path via unit + bash bats — surface: Surveyor's F3 bats↔coverage differential (9/11 fully covered, Option-A split honest); 11-case full harness disclosed-deferred as ratified
go vet ./... + golangci-lint run clean — surface: CI gate confirms

All 5 ratified forks built (bus 94c4 → 246d + 88ce):

F1 4-STATE verdict (skip|pass|warn|fail)
F2 placement split (gates + cmd/rt)
F3 Option A coverage split (rejected Option B substrate-scope contamination)
F4 no events (not applicable — sources forgejo-api.sh, not events.sh)
F5 leak-guard port for #94/#260

Favorable-substrate anchor confirmed in code: forgejo.Client accretion=ZERO. All 3 reads needed (GetDefaultBranch + GetAuthenticatedUser + GetBranchProtection) + BranchProtection struct EXIST from Phase 4, built SPECIFICALLY for this consumer per BranchProtection struct doc comment.

Surveyor's should-consider (non-blocking): bats #10 no-arg→alpha default lacks zero-arg Go unit pin. Behavior verified correct + byte-identical to bash — cheap parity test, not a bug. Engineer's call whether to fold into #572 build or defer as micro-follow-up.

Correction cycle anchors for Phase 6b substrate-of-record:

Favorable-substrate direction confirmed empirically: forgejo.Client accretion=ZERO validated by actual build (not just framing-verify prediction)
Milestone-language-generalization at n=2 (this tracker): 4-STATE verdict; per-validator oracle-shape wins over §5 generalization

Refinement accounting: Cutter 3/5 STAYS FIRM. forgejo.Client STAYS at 3 (unchanged). internal/gates gains PreflightPushWhitelist (additive; sibling to ManifestPrecheck from #571).

Phase 6b status: 2/6 sub-trackers CLOSED. Engineer on #572 build (framing-verify done, 8 forks ratified). Remaining sequence: #572 → #567/#568/#569 wire-existing-gates.
