feat: add board Generate Now smoke spec (M4, skip-if-absent) — v1.5.0

Adds 06-board-generate-now.spec.ts for the PRAutoBlogger board Generate
Now control shipping in v0.21.0 (PR #166). Two tests:

1. Board page loads and #prab-generate-now button is present with nonce.
2. Kick-off AJAX (prautoblogger_generate_now) returns valid JSON — no PHP
   fatal, no wp_send_json_error from a missing nonce.

SKIP-IF-ABSENT: when #prab-board or #prab-generate-now is absent (M4 not
yet deployed) both tests skip with loud annotations so this e2e PR can
merge before prautoblogger PR #166 per the M2/M3 merge-order binding.

READ-ONLY: never waits for generation to complete; kick_off() is
idempotent (guards against duplicate cron scheduling).

+# Changelog
+
+All notable changes to the peptide-e2e smoke suite will be documented here.
+
+## [1.5.0] - 2026-06-14
+
+### Added
+- **Board Generate Now smoke (M4, skip-if-absent)** (`06-board-generate-now.spec.ts`).
+  Asserts the PRAutoBlogger board page loads, `#prab-generate-now` button is present
+  and carries a nonce, and the kick-off AJAX action returns valid JSON (no PHP fatal).
+  READ-ONLY: never waits for generation to complete; `kick_off()` is idempotent.
+  SKIPS with a loud annotation when `#prab-board` or `#prab-generate-now` is absent
+  (v0.21.0 M4 not yet deployed) so the e2e PR can merge before prautoblogger PR #166
+  per the M2/M3 merge-order binding. 27 tests total (was 25), delta = 2.
+
+## [1.4.0] - 2026-06-12
+
+### Added
+- **Dossier edit + re-run smoke (M3, skip-if-absent)** (`05-dossier-edit.spec.ts`).
+  Opens a discovered post's dossier and exercises the v0.20.0 edit surface READ-ONLY:
+  opens/closes the first edit panel (asserts textareas, Save/Re-run buttons, the
+  fork-preserved + queued-execution copy), asserts every disabled edit affordance
+  carries a visible reason, and checks the M3 sidebar cards (Run Spend, Models &
+  Prompts). NEVER clicks Save or any Re-run button (those fork inputs / queue paid
+  LLM jobs). SKIPS with a loud annotation when `.prab-stage-rerun-footer` is absent
+  (plugin v0.20.0 not yet deployed) so this PR can merge before prautoblogger PR #161
+  per the M3 merge-order binding. 25 tests total (was 24), delta = 1.
+
+## [1.3.0] - 2026-06-12
+
+### Fixed
+- **Auth setup survives `ERR_ABORTED` on wp-login.php** (`global.setup.ts`).
+  When Hostinger's LiteSpeed throttles a GitHub runner IP, `page.goto` can
+  throw `net::ERR_ABORTED` rather than a `TimeoutError`. Playwright marks the
+  browser context closed internally on abort, so the existing
+  `context.close()` call in the catch block threw
+  `"browserContext.close: Target page, context or browser has been closed"`,
+  which propagated out of catch and killed setup before the remaining retries
+  ran. Two production deploys were blocked by this flake on 2026-06-12.
+
+  Fix: introduced `safeClose()` helper that swallows the already-closed
+  error, so an aborted context never terminates the retry loop. Max attempts
+  raised from 3 → 5; backoff is now exponential (5 s / 10 s / 20 s / 40 s)
+  instead of a flat 15 s, giving the throttle window more time to clear.
+  Worst-case timing: 5 × 90 s navigation + 75 s backoff = ~525 s, well under
+  the 900 s (15 min) job timeout. Final-failure message explicitly names the
+  LiteSpeed throttle hypothesis so future CI logs self-diagnose.
+
+## [1.2.0] - 2026-06-12
+
+### Added
+- **Dossier page smoke test** (`03-admin-plugins.spec.ts` — `WP Admin — PRAutoBlogger Article Dossier`).
+  Navigates to `/wp-admin/admin.php?page=prautoblogger-dossier&post_id=<N>`, asserts HTTP 200,
+  `#prab-dossier` container visible, body does NOT contain "Invalid plugin page" or "Fatal error".
+  Guards against: menu-ordering regression (wrong hookname → wp_die 404), PHP fatals on dossier
+  load, missing dossier container, and stage-section regression.
+
+  Defensive strategy: tries canonical staging post IDs 925/930 first, then falls back to the
+  most recent REST post, then falls back to post_id=0 (graceful empty state). Stage-section
+  assertions are conditional on a run record existing. Loud test.info() annotations on fallback
+  paths. New in PRAutoBlogger v0.19.2 / v0.19.3.
+
+## [1.1.0] - 2026-06-12
+
+### Added
+- **Board page smoke test** (`03-admin-plugins.spec.ts` — `WP Admin — PRAutoBlogger board page`).
+  Navigates to `/wp-admin/admin.php?page=prautoblogger-board`, asserts HTTP 200,
+  `#prab-board` container visible, and body does NOT contain "Invalid plugin page".
+  Guards against the v0.19.1 regression class: Board submenu registered before parent
+  menu existed (both at admin_menu priority 10) → WordPress fallback hookname →
+  wp_die 404. Now in the deploy-gate smoke suite so this failure class is un-shippable.
+
+  Note: cannot be validated against prod until v0.19.1 of PRAutoBlogger deploys.
+  Spec compiles and lists cleanly under `npx playwright test --list`.
+
+## [1.0.0] - 2026-06-11
+
+Initial release. 21 tests across 5 specs: homepage, reconstitution calculator,
+peptide search, admin plugins, REST API.

  * The saved auth state (playwright/.auth/admin.json) is reused by the

+ * wp-login.php, causing TimeoutError on page.goto. The login attempt is now
+ * retried up to MAX_ATTEMPTS times with a fresh browser context per attempt
+ * and BACKOFF_MS delay between attempts so transient throttle windows clear.
+ *
+ * Retry hardening (2026-06-12 v2 — ERR_ABORTED fix): When Hostinger aborts

+ * remaining retries. Fix: context.close() is now guarded in its own
+ * try/catch so an already-closed context never aborts the retry loop.
+ * MAX_ATTEMPTS raised to 5; backoff doubled each time (5s/10s/20s/40s) so the

+/**
+ * 05-dossier-edit.spec.ts
+ *
+ * What: Smoke for the PRAutoBlogger dossier EDIT + RE-RUN surface
+ *       (plugin v0.20.0, Phase 2 admin M3). Read-only: opens/closes the
+ *       edit panel and asserts structure — it NEVER clicks Save or any
+ *       Re-run button (those fork inputs / queue paid LLM jobs).
+ * Who triggers it: Playwright chromium project (post-auth setup).
+ * Dependencies: wp-admin authenticated session (from global.setup.ts).
+ *
+ * SKIP-IF-ABSENT (M3 binding): this spec targets a surface that may not
+ * be deployed yet. When the M3 markup (.prab-stage-rerun-footer) is
+ * absent from the dossier, the test SKIPS with a loud annotation so this
+ * PR can merge before the plugin PR ships. Once v0.20.0 is live, the
+ * skip path goes dead and the assertions gate as usual.
+ *
+ * Selectors sourced from prautoblogger v0.20.0:
+ *   templates/admin/dossier-stage-section.php  (.prab-stage-rerun-footer,
+ *     .prab-edit-toggle, .prab-edit-unavailable, .prab-rerun-from)

+ * What: Smoke for the PRAutoBlogger board "Generate Now" control (v0.21.0, M4).
+ *       Asserts that the board page renders the generate-now button and that
+ *       clicking it sends the kick-off AJAX request without a PHP fatal.
+ *       Read-only assertions only — this test NEVER waits for article generation
+ *       to complete (that would make LLM API calls in CI).
+ *
+ * SKIP-IF-ABSENT (M4 binding): the generate-now surface ships with v0.21.0
+ *   (prautoblogger PR #166). This spec guards against the board container
+ *   (#prab-board) being absent or the generate-now button (#prab-generate-now)
+ *   missing. When those selectors are absent (v0.21.0 not yet deployed), the
+ *   entire test suite skips with a loud annotation so this PR can merge before
+ *   the plugin PR — matching the M2 merge-order binding.
