feat(editor): in-editor reauth — Milestone A (password path)

[dknauss]

Summary

• What is this? The tracking home for Milestone A of the in-editor (Gutenberg) reauthentication modal. This branch carries a working password-grant modal floor (25c2e72) that was built, manually demoed in Playground, then parked so 4.6.0 could ship only the safe Increment 1 (link-out) + Increment 2 (server grant plumbing). This PR revives it as a tracked, reviewable work item and adds the milestone plan.
• What it does: on a sudo_required REST rejection inside the block editor, an apiFetch middleware opens a single-flight wp.components.Modal (build-free), grants the sudo session via AJAX (session-only, user's own wp_rest/wp_sudo_challenge nonces — C3), then transparently re-dispatches the original request so the action completes without leaving the editor. A stale grant nonce is refreshed first. 2FA / cancel / no-config fall back to the Increment-1 link-out to the full challenge page.
• Scope decision (this PR = Milestone A only): password path, finished and hardened. Non-2FA users get the modal; 2FA and passkey users link out (identical to today's 4.6.0 — no regression, no 2FA bypass: the server mints the session and returns 2fa_pending for 2FA accounts, which the modal bounces to the full challenge). In-modal 2FA is Milestone B. Rationale + full task/gate breakdown: .planning/gutenberg-editor-reauth-milestone-plan.md; technical detail + C1–C4 + security-config in the phase-2 plan.

Validation

• composer test — not yet run for this milestone. This is a WIP draft, not merge-ready. The modal has no automated verification yet: editor-reauth.spec.ts EDITOR-06 (modal grant) and the superseded snackbar tests are test.fixme; only code-level review passed.
• Milestone A exit gates (must all pass before un-drafting): rebase onto current main (branch is 9 behind); de-fixme + finish EDITOR-06; 2FA-bypass invariant test (a 2FA account's password-only modal call must never grant); stale-nonce recovery test; password-manager/autofill matrix; single-site and WP_MULTISITE=1 E2E green; degradation + headless-challenge_url (C4) regression; mandatory security-scoped review of the real diff with the C1–C4 checklist; docs/current-metrics.md synced.
• Runtime/E2E/wp-env/password-manager verification runs in a browser-capable session (not the headless build sandbox).

Checklist

• Linked issue / rationale — implements the "Stabilize … in-editor reauth" roadmap track; scope recorded in the milestone plan (this PR adds it).
• Updated docs / tests — planning docs added; tests still test.fixme (Milestone A work).
• No sensitive details disclosed publicly.

⚠️ Do not merge as-is. Draft tracking home; the modal code predates the Milestone-A gates above. First task is a rebase onto main.

▶ START HERE — executing Milestone A (browser-capable session)

This PR is a parked WIP tracking home, not merge-ready. Milestone A needs a browser-capable session (wp-env / Docker / real browsers + password managers) — the headless build sandbox can't run those. Launch with /Users/danknauss/bin/claude-playwright (or the browser handoff), then work this branch.

Read first (in order):

1. .planning/gutenberg-editor-reauth-milestone-plan.md — scope, A/B split, what's built vs. unverified, per-milestone gates.
2. .planning/gutenberg-editor-reauth-phase2-plan.md — the how: Tasks 1–7, C1–C4, and Part 7 (security-config). Hand the C1–C4 checklist to the reviewer explicitly — the generic pre-commit reviewer won't know them otherwise.

Current state (facts):

• Modal floor built on 25c2e72: apiFetch-detect → single-flight wp.components.Modal → AJAX session-only grant → transparent re-dispatch (C3); refreshNonceAction for stale grant nonce; 2fa_pending/cancel/no-config fall back to the Increment-1 link-out.
• Branch is 9 commits behind main (merges clean). E2E is unverified: editor-reauth.spec.ts EDITOR-06 (modal grant) + the superseded snackbar tests are test.fixme; only EDITOR-04 is active.

First tasks:

1. Rebase onto main (reconcile admin/js/wp-sudo-editor-reauth.js + includes/class-plugin.php against the shipped Increment-1/2 code).
2. De-fixme and finish EDITOR-06 against live wp-env; reconcile/retire EDITOR-01/02/03/05.
3. 2FA-bypass invariant test (the security gate): a 2FA-enabled account's password-only modal call must never return a granted session — assert at the AJAX layer and E2E (2FA acct → modal password → no grant → link-out).
4. Stale-nonce recovery test (aged/overnight-tab, not just nonce-valid).
5. Password-manager/autofill matrix (1Password / Bitwarden / Keychain / built-ins) against the createElement field; apply cheap markup fixes.
6. REST boundaries: single-flight + concurrent-queue (Q3); batched-envelope detect-and-surface (Q2, no silent no-op).
7. Degradation + headless challenge_url-free regression (C4).

Exit gates (all required before un-drafting): rebased; EDITOR-06 + bypass-invariant + stale-nonce + degradation green on single-site AND WP_MULTISITE=1; password-manager matrix recorded; C1–C4 verified; composer analyse (PHPStan+Psalm) + integration suite pass; pre-commit reviewer flag on every code commit; security-scoped review of the real diff; docs/current-metrics.md synced; release notes state the 2FA-links-out fallback.

Scope: password path only. In-modal 2FA (server-rendered provider partial; WebAuthn stays link-out) is Milestone B — a separate follow-up on top of this.

⚠ Step 1 env guard — verify WP Sudo's own wp-env before running E2E

Learned the hard way during Step 0 handoff prep: "a WordPress answers on localhost:8889" does not mean it's WP Sudo's env. On this machine that port was an unrelated Pixel environment reached through an SSH tunnel — WP Sudo was not installed on it at all.

Consequences if you don't check:

• EDITOR-04 passes vacuously. With nothing gating requests, "a normal error does not surface the modal" is trivially true — a green EDITOR-04 can mask a completely dead target.
• EDITOR-06 fails for the wrong reason (no plugin → no modal), which looks like a code bug but isn't.

Do this before trusting any E2E result:

1. Authenticated GET /wp-json/wp/v2/plugins → confirm a WP Sudo entry with status: active.
2. Sanity-check a gated apiFetch (e.g. PUT /wp/v2/plugins/hello {status:'active'}) is rejected with a sudo_required-class code — not resolved. If it resolves, gating isn't active → wrong/dead env.

Also: on this session wp-env start (even on free ports) brought up MySQL only — the WordPress containers were never created (exit 0), likely the deprecated .wp-env.json testsPort/env options + the custom WP 7.0 core zip. Don't assume exit-0 == provisioned; verify WordPress is actually reachable and that it's the Sudo env.

Guard is now recorded at the top of Step 1 in .planning/gutenberg-editor-reauth-execution-checklist.md (commit 041c7db).

Context: Step 0 (rebase) is complete — rebased clean onto main, gates green, force-pushed. Step 1+ need the browser-capable session (claude-playwright) with WP Sudo's own wp-env.

✅ Ready E2E env for Step 1 — WordPress Studio (localhost:8881)

The Step 1 env guard is now satisfied with a provisioned, verified environment — no wp-env needed. Provisioned via WordPress Studio and confirmed working end-to-end.

Environment

Piece	State
Site	Studio "Sudo Test" → http://localhost:8881 — Online, WP 7.0.1, PHP 8.5
Plugin	wp-content/plugins/wp-sudo symlinked to the repo (live mount → tracks branch feat/gutenberg-reauth-increment-3), activated, v4.6.0
Served build	Confirmed this branch's modal JS (wp-sudo-editor-reauth.js?ver=4.6.0, components.Modal present)
Admin	admin / password with all four governance caps (manage_wp_sudo, view_wp_sudo_activity, export_wp_sudo_activity, revoke_wp_sudo_sessions)
Gating proven	With wp_sudo_* cookies stripped (as global-setup does), a gated apiFetch opens the modal — "Confirm your identity", password field, Confirm button. All three EDITOR-06 selectors verified live.

Run Step 1 against it (the harness defaults to wp-env on :8889, so target Studio explicitly and skip the wp-env-only cap step — caps are already set):

WP_BASE_URL=http://localhost:8881 WP_SUDO_SKIP_WP_ENV_CAP_SETUP=1 npm run test:e2e:local

global-setup already logs in as admin/password, strips wp_sudo_* cookies, and works against this site (verified by mirroring its exact flow).

Studio CLI cheatsheet (bundled at /Applications/Studio.app/Contents/Resources/bin/studio-cli.sh):

• … status --path ~/Studio/sudo-test — site URL / online state
• … start --path ~/Studio/sudo-test — start if offline
• … wp --path ~/Studio/sudo-test <wp-cli …> — WP-CLI passthrough (note: plugin toggles are themselves sudo-gated on the CLI surface)

Baseline note: Hello Dolly is currently active; EDITOR-06's PUT /wp/v2/plugins/hello {status:'active'} still fires the gate on the request (proven), so it passes regardless of current state.

Remaining Step 1 work (browser session): un-fixme EDITOR-06 (selectors already confirmed) → green with the command above; reconcile EDITOR-01/02/03/05 (retire or repoint to link-out; keep EDITOR-04); update docs/current-metrics.md E2E count in the same commit; reviewer flag on the code commit.

Milestone A un-drafted — ready for review

The in-editor reauth password path is complete. This turn landed Steps 3–7 of the execution checklist:

• Step 3 — stale-nonce recovery: handle_ajax_refresh_nonce() re-mints the single wp_sudo_challenge nonce (login-gated, no stale-nonce requirement); regression-guarded server-side (StaleNonceRecoveryTest) and client-side (EDITOR-09).
• Step 4 — Q3 owner-scoped re-dispatch: on a grant, only the request that opened the modal re-dispatches; concurrent non-owner rejections are left rejected (no surprise mutation). Design-reviewed (owner-only over replay-all) + EDITOR-10/11. Clears the Q3 un-draft blocker.
• Step 5 — Q4 label suppression: the reauth UI never echoes the rule label (RestGatingTest server boundary + EDITOR-12); headless challenge_url-free already covered.
• Step 6 — autofill markup audit: docs/password-manager-compatibility.md (both surfaces expose the standards-minimal password-autofill set).
• Step 7 gates: integration 219/0 single-site AND multisite, PHPStan+Psalm 0 errors, lint 22/22, verify:metrics + verify:i18n in sync, editor-reauth.spec.ts 12/12 on a live env. A security-scoped C1–C4 review of the branch was clean (2 LOW residuals, no code change).

The b86de6b commit message was amended to cite the verified WordPress/two-factor source (class-two-factor-email.php) per the repo's third-party-verification rule (history rewrite + force-push).

Remaining pre-merge (not blockers to review, but before merge)

1. Full/multisite E2E sweep — npm run test:e2e:local (all specs) + :multisite in CI/wp-env. This branch touches only the editor-reauth spec (green) + its middleware JS, so nothing else can regress; the sweep is a release-gate formality.
2. Password-manager matrix — the manual per-manager autofill verification (incl. the 1Password-with-2FA repro) in docs/password-manager-compatibility.md is pending (needs a human with those managers).

2FA accounts link out to the full challenge page (password-only in-editor for now); the 2FA-bypass invariant is enforced and regression-guarded at all three layers.

Avoid double-prompting 2FA users before link-out

For accounts with 2FA enabled, this branch runs only after the user has already entered a correct password in the modal, then falls back to the full challenge. The full challenge page still starts on the password form and keeps the 2FA step hidden until its own password AJAX returns 2fa_pending (includes/class-challenge.php:371, revealed by admin/js/wp-sudo-challenge.js only after another password submit), so these users must enter their password twice before reaching 2FA. That regresses the previous link-out path for any 2FA account; either skip the modal for known-2FA users or have the challenge page consume the existing pending state directly.

Useful? React with 👍 / 👎.

Final review: no blocking findings from my side.

What changed since the last review:

• Fixed the docs-lint blocker on docs/password-manager-compatibility.md in commit 94b992e.
• Added a manual password-manager verification protocol plus a focused 1Password + Two Factor repro target, without recording unverified manager behavior as fact.

Validation:

• Local composer test:unit: pass, 1027 tests / 3104 assertions.
• Local composer lint: pass.
• Local composer analyse: pass.
• PR CI on head 94b992e: all checks pass, including all four wp-env E2E shards and challenge-replay-multisite.

Remaining-items take:

• I would not dispatch extra release-confidence or Nginx/MariaDB multisite E2E solely for this PR. The relevant PR wp-env E2E and multisite integration coverage are green; reserve the heavier workflow for release-candidate confidence.
• The password-manager matrix is now scaffolded for human-local verification. I did not inspect or automate vault contents; those observations should be filled from a real local browser profile.
• Q3 owner=request assumption is not a merge blocker. Worst case remains UX or request semantics, not auth bypass. A good follow-up would encode a per-request owner/queue so only the initiating request is retried after grant.

Approved from my side.
