ci(review): drop panel to Haiku-only per QA A/B decision 2026-06-12

A/B analysis across 13 PRs (convo/cto/threads/2026-06-qa-ab-review/02-analyst-findings.md):
- DeepSeek: high false-positive rate (absint()="code exec", PLUGIN_DIR="dir traversal")
- Kimi: ~60% model failure rate, 1 unique-real finding in 13 PRs
- Neurometric: summarizer only, 0 unique-real findings, unreliable heuristic verdict label
- Haiku: 0 failures, lowest noise, equivalent real-signal catch vs 4-voice panel

Removes DeepSeek, Kimi, and Neurometric voices. Haiku is now sole reviewer.
Also removes NEUROMETRIC_API_KEY env var (no longer needed).
No plugin version bump -- CI-only change (precedent: prautoblogger #150).

 ### #20: PHPUnit test infrastructure + WordPress-Core PHPCS compliance (v0.10.1)
 
 Tests use Brain\Monkey for WordPress function mocking (no database required). The BaseTestCase singleton handles setup/teardown of Monkey stubs and provides fixture helpers for common data shapes (SourceData, ArticleIdea, GenerationLog, etc.). All WordPress functions used by the plugin are stubbed in BaseTestCase::setUp() so individual test classes only override what they need. In v0.10.1, missing stubs for `post_type_exists()` were added to support PeptideLinker's PR-Core guards. All 1,362 WordPress-Core coding-standards violations (short array syntax, line length, spacing) were auto-fixed via phpcbf and the CI gate was flipped to strict mode — PHPCS failures now block CI. This prevents future regressions on the code style front.
 
 
+
+### #22b: Kanban board as primary admin landing screen (v0.19.0 / v0.19.1)
+
+**Hidden admin page convention (v0.19.3):** See CONVENTIONS.md §Hidden Admin Pages for the full rule. Summary: hidden admin pages (link-accessed only, not visible in nav) MUST use `options.php` as the `add_submenu_page()` parent. NEVER unset/remove registered pages from `$submenu` after registration -- doing so causes `get_admin_page_parent()` to fail at request time, which makes WP recompute the hookname in the `admin_page_*` orphan namespace, find no registered handler, and call `wp_die(403)`. This is the dossier 403 incident (v0.19.2→v0.19.3). Same hookname-mismatch class as the board 404 (v0.19.0→v0.19.1); the only difference is that the board bug was a priority-ordering issue at registration time while the dossier bug was a post-registration $submenu mutation.
+
+The primary admin screen is now a kanban board (Direction C "Editorial Record") with four
+columns: Generating | In Review | Published | Failed. A separate `class-board-page.php`
+registers the `Board` submenu and a `$submenu` reorder makes it the first (primary) entry.
+`class-board-data-provider.php` orchestrates the four columns and handles WP_Query columns
+(In Review, Published). Raw `prab_generation_log` queries (Generating, Failed) are in the
+extracted `class-board-gen-log-query.php` (split for 300-line compliance) -- no new schema
+required for M1. The data provider uses the `prautoblogger_generation_status` transient
+(written by the Executor for manual/daily runs) as the primary active-run signal, with a
+secondary query on recent `prab_generation_log` run_ids that have no linked post as a
+fallback. M2 will rename Runs & Audit -> Articles and wire board cards to the Article Dossier.
+Poll interval and published window are settings-backed, localized into board.js, never
+hardcoded.
+
+**Menu-ordering constraint (v0.19.1 hotfix):** `PRAutoBlogger_Board_Page::on_register_menu`
+MUST be hooked at `admin_menu` priority 11 (or higher), AFTER
+`PRAutoBlogger_Admin_Page::on_register_menu` which runs at priority 10. Reason: WordPress
+computes the page hookname via `get_plugin_page_hookname()` at `add_submenu_page()` call
+time. If `add_menu_page()` has not yet run, `$admin_page_hooks['prautoblogger-settings']`
+is unset and WordPress falls back to the `admin_page_*` hookname. At HTTP request time WP
+recomputes the hookname as `prautoblogger_page_prautoblogger-board` and finds no registered
+callback -> `wp_die("Invalid plugin page")` 404. The enqueue-gate in `on_enqueue_assets()`
+checks `prautoblogger_page_prautoblogger-board` and would similarly never fire with the
+wrong hookname (board.css/board.js would silently not load). Regression test:
+`tests/unit/Admin/BoardMenuRegistrationTest.php`.
+
+
+### #23: Article Dossier page — per-article inspection (v0.19.2)
+
+The dossier is a read-only per-article admin page that exposes the full substrate view for
+a single post: generation run, stage I/O, cost receipts, raw-trace toggles, editorial
+decisions, and image A/B pairs. It is link-accessed only (hidden submenu) — no navigation
+entry appears in the WP sidebar.
+
+**Page registration** (`class-dossier-page.php`): uses the canonical hidden-admin-page
+pattern -- registered under parent **`options.php`** at `admin_menu` priority **12**. The
+hookname is `admin_page_prautoblogger-dossier` at BOTH registration time and request time,
+so there is no hookname mismatch and no need to manipulate `$submenu`. The page does not
+appear in the WP admin sidebar (options.php-parent pages are hidden by construction).
+URL shape: `admin.php?page=prautoblogger-dossier&post_id=<int>` (unchanged from v0.19.2 --
+deep-link URLs are parent-agnostic). Secured by `manage_options` capability. Static
+`url_for_post(int $post_id): string` provides the canonical deep-link.
+
+v0.19.2 used `prautoblogger-settings` as parent with post-registration `unset($submenu[...])` to
+hide the page. This caused `get_admin_page_parent()` to fail at request time -> orphan
+`admin_page_*` hookname -> no handler registered -> `wp_die(403)`. Fixed in v0.19.3 by switching
+to `options.php` parent and removing all `$submenu` mutation. See CONVENTIONS.md §Hidden Admin
+Pages for the full rule and ARCHITECTURE.md §22b for both incident records.
+
+Regression test: `tests/unit/Admin/DossierMenuRegistrationTest.php` -- the
+`test_request_time_hookname_matches_registration_hookname` test replicates the request-time
+resolution algorithm (simulate `get_admin_page_parent()`) so it FAILS on hide-by-unset and
+PASSES on options.php-parent.
+
+**5-query data assembly** (`class-dossier-data-assembler.php`):
+
+```
+1. wp_prautoblogger_runs       WHERE run_id = %s             -- 1 row (run metadata)
+2. wp_prautoblogger_run_stages WHERE run_id = %s             -- N rows (per-stage status/cost)
+3. wp_prautoblogger_generation_log WHERE run_id = %s         -- N rows (model/pv/tokens/request)
+4. wp_prautoblogger_run_decisions WHERE run_id = %s          -- N rows (editorial rationale)
+5. get_post_meta($post_id)                                    -- WP object cache hit
+```
+
+All queries are keyed on `run_id` (indexed). No N+1. Stage output is reconstructed from
+`run_stages.meta_json → json_decode → meta['output']` (same path as `Run_Stage_State::
+get_output()`). The dossier assembler does NOT call `Run_Stage_State` directly; it performs
+its own raw queries so the view is not coupled to the cache layer.
+
+**Legacy graceful state (binding 5):** Posts published before v0.18.0 (no runs/run_stages
+rows) and posts where `_prautoblogger_run_id` is absent or blank return `['has_run' => false]`.
+The template renders a clean "No generation record for this article" notice. No PHP notices
+or fatals.
+
+**Amortized research rows:** `generation_log` rows with `prompt_version = NULL` and
+`agent_role = ''` (from the `llm_research` stage orphan-reaper path) are rendered with
+model shown as "—" and no raw-trace toggle (request_json may be NULL). No fatal/notice.
+
+**Raw-trace security (binding 4):** `request_json` stores the OpenRouter request body —
+model identifier, messages array, temperature. Authorization headers are never logged (the
+outbound HTTP client strips them before logging, per the original architecture decision on
+`wp_prautoblogger_generation_log`). The dossier template renders `request_json` via
+`esc_html()` inside a `<pre>` block. All model-generated text rendered via `wp_kses_post()`
+(rendered view) or `esc_html()` (raw trace). Both paths treat content as untrusted HTML.
+
+**File naming note:** `PRAutoBlogger_DB_Migrations` is loaded via explicit `require_once`
+in `prautoblogger.php` (not the autoloader). The autoloader converts `DB_Migrations` to the
+kebab segment `d-b-migrations`, producing `class-d-b-migrations.php` — which does not match
+the file `class-db-migrations.php`. Explicit loading is the canonical pattern for classes
+whose names do not round-trip cleanly through the kebab converter. `class-prautoblogger.php`
+uses the same pattern (also explicitly required in `prautoblogger.php`).
+
 ## Cross-System LLM Budget Coordination
 
 PRAutoBlogger and Peptide News both call OpenRouter and may share a single API key / billing account. Their combined spend should be considered when setting per-plugin budgets.

-- **Versioned prompt registry** (`PRAutoBlogger_Prompt_Registry` + `_Writer`): all pipeline
-  prompt copy — content system/single-pass/outline/draft/polish, analysis system/user,

-  image Style Template** (the image-composer PR seam) — is seeded as immutable version 1
-  from the v0.16.0 hardcoded texts (`prautoblogger_migrated_prompt_seed_v0180`). One active

-  registry with a **byte-identical in-code fallback** when the table is missing/empty
-  (self-healing, no fatals on half-migrated state). No admin UI in Phase 1.
-- **Prompt-version pinning**: `Cost_Tracker::set_run_id()` pins the active version of every
-  key on the run's row; every generation_log row (text and image stages) is stamped with the
-  pinned `prompt_version` plus a stage-derived `agent_role`. Single-pass rows keep stage
-  `draft` and stamp `content.single_pass` explicitly.
-- `PRAutoBlogger_Run_State` (runs-table ledger row: ceiling/reserved/settled/overage, pins,
-  sticky lifecycle states) and `PRAutoBlogger_Run_Context` (per-process run id, mirrors the
-  Opik trace-context pattern).
-
-- **Per-run cost governor** (`PRAutoBlogger_Cost_Governor`, net-new enforcement — previously
-  only the monthly cap was enforced): every `send_chat_completion()` reserves its worst-case
-  estimate (prompt chars/4 + max_tokens, priced via the #18 chain) against the run ledger
-  with a single atomic conditional UPDATE (the #10 lock discipline) BEFORE dispatch; the
-  image `curl_multi` batch reserves its summed estimate before dispatch; reservations settle
-  to actuals after each response (a failed call releases its hold). Breach → run `halted`
-  (sticky), overage recorded, `Cost_Ceiling_Exception` aborts the call, remaining queued
-  articles abort, and the run is surfaced in a "Halted runs" notice on the Review Queue.
-  New setting **Per-Run Cost Ceiling (USD)** (`prautoblogger_per_run_cost_ceiling_usd`,
-  default `PRAUTOBLOGGER_DEFAULT_RUN_CEILING_USD` = $0.50, snapshotted at run start,
-  0 = disabled). Calls outside a run, the monthly budget, and the Cloudflare AI Gateway
-  path behave exactly as before.
-
-- **Run state machine + idempotent resume** (`PRAutoBlogger_Run_Stage_State`): per-run
-  per-stage rows keyed `run_id + stage + agent_role + item_key` (item_key scopes
-  article-level stages — one run_id spans all N articles of a batch; agent_role is the
-  Phase-2 quorum dimension, schema-only for now). Done stages snapshot their output and are
-  REUSED on re-entry — never re-run, never re-charged (writer stages via
-  `Content_Generator::set_run_item()`, the editorial review via its stored verdict, a fully
-  published item is skipped outright). **Post creation is keyed by `_prautoblogger_run_id`
-  + new `_prautoblogger_idea_hash` meta (check-before-insert)** so a retried run cannot
-  create a duplicate post. Run-level research/analysis checkpoints ride Pipeline_Runner;
-  completion/failure marks land on the runs row (Executor catch paths, orphan aborts,
-  monthly-budget aborts).
-- **Reaper extension** (`PRAutoBlogger_Run_Reaper`, same daily cron as the #19 research
-  reaper — no new schedule): stages stuck `running` > 2× expected stage wall-clock and runs
-  silent > 2× expected run wall-clock are marked `failed` (filterable expectations); their
-  open stages are reaped; such runs are queryable as **"incomplete"** via
-  `Run_Reaper::incomplete_runs()`. Also enforces **retention**: `request_json` on the
-  generation log and stage output snapshots are NULLed after R days — R from the new
-  **Audit Payload Retention** setting (`prautoblogger_request_json_retention_days`, default
-  `PRAUTOBLOGGER_DEFAULT_REQUEST_JSON_RETENTION_DAYS` = 14, 0 = keep forever).
-- **Audit writes** (`PRAutoBlogger_Audit_Writer`): every reviewed article records its
-  editorial verdict in `run_decisions`; every published article records the sources that
-  fed it in `run_sources` (the source_ids_json / `_prautoblogger_research_sources`
-  consolidation for new runs; no backfill).
-
-### Changed
-- `Content_Generator`'s four stage methods now share one `execute_stage()` helper (the Opik
-  span + dispatch + cost-log boilerplate was identical); file drops from 301 to ~220 lines.
-  No behavior change: same prompts, models, params, span names, stage values.
-- `Cost_Tracker::get_avg_tokens_for_stages()` body moved to `Cost_Reporter` (read-only
-  reporting query); the Cost_Tracker method remains as a delegating wrapper.
-- `OpenRouter_Provider`'s API-key fetch + format validation moved to
-  `OpenRouter_Request_Builder::resolve_api_key()` (300-line cap); identical messages/behavior.
-- Pipeline_Runner's and Article_Worker's duplicated status-transient/summary helpers moved
-  verbatim to the new `PRAutoBlogger_Pipeline_Status` (Pipeline_Runner back under the
-  300-line cap at 271).

+### Fixed
+- **Dossier page 403 (P0 hotfix).** `PRAutoBlogger_Dossier_Page::on_register_menu` registered the
+  dossier as a hidden submenu under `prautoblogger-settings` then called `unset($submenu[...])` to

+  the render callback under hookname `prautoblogger_page_prautoblogger-dossier`; at request time
+  `get_admin_page_parent()` scans `$submenu`, finds the slug absent (it was unset), returns false,

+  **Fix:** register under parent `options.php` (canonical hidden-page pattern). Hookname is

+  was hooked at `admin_menu` priority 10, identical to

+  `$admin_page_hooks['prautoblogger-settings']` was still unset. WordPress fell back
+  to the `admin_page_prautoblogger-board` hookname; at request time it recomputed
+  `prautoblogger_page_prautoblogger-board`, found no registered callback, and called
+  `wp_die()` with "Invalid plugin page". Board CSS/JS also never loaded (same
+  enqueue-gate mismatch). Fix: parent menu hook stays at priority 10; board submenu
+  hook moves to priority 11, guaranteeing `add_menu_page()` fires first. Board is

+## Hidden Admin Pages (v0.19.3 convention, codified after two incidents)
+
+### Rule: use options.php as parent; NEVER unset/remove registered pages from $submenu
+
+When a WordPress admin page must be accessible by URL but hidden from the nav menu, use the
+**options.php-parent pattern** exclusively:
+
+```php
+add_submenu_page(
+    'options.php',                     // parent: built-in WP page; pages hidden by construction
+    __( 'My Page', 'prautoblogger' ),  // page title
+    __( 'My Page', 'prautoblogger' ),  // menu title (never shown; options.php is hidden)
+    'manage_options',                  // capability
+    'my-page-slug',                    // page slug
+    array( $this, 'render_page' ),     // callback
+);
+// No $submenu manipulation. options.php-parent pages are hidden from nav by construction.
+```
+
+The resulting hookname is `admin_page_my-page-slug` at BOTH registration time and request time.
+
+### Why the hide-by-unset pattern causes 403 (the incident class)
+
+WordPress computes the page hookname at two distinct moments:
+
+**Registration time** (inside `add_submenu_page`):
+WP resolves the parent slug against `$admin_page_hooks`. If found, hookname = `{parent_key}_page_{slug}`. WP registers the render callback and `$_registered_pages` entry under that name.
+
+**Request time** (inside `wp-admin/admin.php`):
+WP calls `get_admin_page_parent()` which scans `$submenu` for the page slug. If found, it derives the hookname the same way as (1). If **not found** (e.g., because the entry was unset), it falls back to `admin_page_{slug}`.
+
+When these two hooknames diverge, WP dispatches the request to a hookname with no registered callback → `wp_die(403)`.
+
+**Why options.php avoids this:** `options.php` is a built-in page that WordPress always keeps intact in `$admin_page_hooks` and `$submenu`. For its children, `get_admin_page_parent()` returns `options.php` consistently at both moments, so both produce `admin_page_{slug}`. No mutation required.
+
+### Incident history
+
+| Version | Symptom | Root cause | Fix |
+|---------|---------|------------|-----|
+| v0.19.1 | Board page 404 | Board submenu registered at same priority as parent (both 10) — add_submenu_page fired before add_menu_page → wrong hookname at registration time | Board moved to priority 11, after parent at 10 |
+| v0.19.3 | Dossier page 403 | Dossier registered under `prautoblogger-settings` parent (priority 12, after parent ✓) but post-registration `unset($submenu[...])` removed the slug → get_admin_page_parent() returned false at request time → orphan `admin_page_*` hookname → no handler → 403 | Switched to `options.php` parent; removed all $submenu mutation |
+
+Both incidents are in the same **hookname-mismatch class**: registration-time hookname ≠ request-time hookname.
+
+### Test pattern
+
+The `DossierMenuRegistrationTest::test_request_time_hookname_matches_registration_hookname` test
+replicates the request-time resolution algorithm (scan `$submenu` for the slug; if found derive
+hookname; if absent return `admin_page_*`) and asserts it equals the registration-time hookname.
+This test FAILS on hide-by-unset implementations and passes on the options.php-parent pattern.
+Apply the same test strategy to any new hidden admin page.
+
+### Asset enqueue gate
+
+For `options.php`-parent pages, the hook suffix passed to `admin_enqueue_scripts` is
+`admin_page_{slug}`. For plugin-parent pages it would be `{parent_key}_page_{slug}`. Always
+match the asset enqueue gate to the actual hookname for the chosen parent pattern:
+
+```php
+// options.php parent → 'admin_page_{slug}'
+public function on_enqueue_assets( string $hook_suffix ): void {
+    if ( $hook_suffix !== 'admin_page_' . self::PAGE_SLUG ) {
+        return;
+    }
+    // ... enqueue
+}
+```

+ * Live-polls the board status AJAX endpoint and updates the four columns

+ * page reload.
+ *
+ * Poll behaviour:
+ *   - Polls at `prabBoard.pollInterval` ms when any article is generating.
+ *   - Doubles the interval (backoff) when `has_active_runs` is false, capping
+ *     at 4× the base interval — prevents needless AJAX on an idle board.
+ *   - Resets to base interval as soon as an active run is detected again.
+ *
+ * Click-throughs (M1):
+ *   - Generating → Activity Log
+ *   - In Review  → Review Queue
+ *   - Published  → Post edit screen
+ *   - Failed     → Activity Log
+ *   (M2 rewires all to Article Dossier)
+ *
+ * Localised config: `prabBoard` object (ajaxUrl, nonce, pollInterval, action,

+ * Empty-completion guard for OpenRouter chat responses (v0.18.1).
+ *
+ * What: Treats a chat completion whose visible content is empty/whitespace
+ *       as a FAILURE, never a success — per the LLM-call discipline:
+ *       schema-validate every output, retry/fall back, never silently
+ *       pass. The incident this prevents (2026-06-11, prod run acf24029,
+ *       draft post 921): a true reasoning model at a high reasoning effort
+ *       spent the entire max_tokens completion budget on thinking,
+ *       finished with finish_reason='length', and emitted zero visible
+ *       content — which flowed writer → editor (reject: "draft text is
+ *       missing") → an empty draft post in the Review Queue, with the
+ *       cost booked as 'success'.
+ *
+ *       Behavior on every parsed response:
+ *       - finish_reason='length' is warning-logged (model, stage, prompt/
+ *         completion/reasoning tokens) whether or not content survived.
+ *       - Empty content + (finish_reason='length' OR reasoning active on
+ *         the request) → ONE retry with reasoning disabled for that call
+ *         (per-call `reasoning` override), then fail the stage.
+ *       - Every failed/retried attempt lands in generation_log with its
+ *         REAL response_status ('error') and token burn, and — inside a
+ *         v0.18.0 run — a run_decisions row records the verdict.
+ * Who triggers it: PRAutoBlogger_OpenRouter_Provider::send_chat_completion()
+ *       on every successfully parsed response.
+ * Dependencies: Logger, Cost_Tracker (failure rows), Run_Context (run
+ *       attribution), Audit_Writer (run_decisions verdicts).

+ *   - fetch_all_text_to_image(): paginates modelSearch and returns raw results.
+ *   - normalize_models(): converts raw results to Image_Model_Registry shape.
+ *
+ * API note (2026-06-12): Runware retired taskType:models. The replacement is
+ * taskType:modelSearch — requires auth+modelSearch tasks, returns paginated
+ * results with `air` identifiers and `capabilities[]`. Text-to-image filtering
+ * is client-side (no server-side capability filter is available). The catalog
+ * has 320k+ entries (mostly community checkpoints); we cap at PAGE_CAP pages
+ * of PAGE_SIZE results to bound request cost while covering curated t2i models.

+ * Tests for Board submenu registration order and hook-suffix correctness.
+ *
+ * Root-cause regression guard for the v0.19.1 hotfix:
+ * Board submenu was registered at admin_menu priority 10 BEFORE the parent
+ * top-level menu page (also priority 10), causing WordPress to record the
+ * render callback under the fallback hookname `admin_page_prautoblogger-board`
+ * instead of the correct `prautoblogger_page_prautoblogger-board`.
+ * At request time WP recomputes the hookname and finds nothing -> wp_die 404.
+ *
+ * ## Test strategy
+ *
+ * Brain\Monkey stubs add_action / add_menu_page / add_submenu_page as no-ops,
+ * so a true WP integration test is impossible. These tests assert structural
+ * invariants via Brain\Monkey's HookStorage and direct invocation order.
+ *
+ * ### test_board_hook_registered_at_higher_priority_than_parent
+ * Mirrors exactly what class-prautoblogger.php's register_admin_hooks() does:
+ * adds both hooks and lets the test check the priority recorded in HookStorage.
+ * - FAILS on origin/main (both add_action calls at default priority 10).
+ * - PASSES after fix (board at priority 11, parent at priority 10).
+ * This test is the true regression guard: revert to both-at-10 = test fails.
+ *
+ * ### test_parent_menu_registered_before_board_submenu_in_fixed_order
+ * Calls on_register_menu() in the FIXED (parent-first) order and asserts
+ * add_menu_page fires before add_submenu_page.
+ *
+ * ### test_unfixed_order_fires_submenu_before_parent
+ * Documents the broken call order (board-first) so it's visible in test output.
+ *
+ * ### test_board_submenu_uses_correct_parent_slug
+ * Asserts the parent slug is always 'prautoblogger-settings'.

+/**
+ * Tests for Dossier admin page hookname faithfulness — request-time mechanism.
+ *
+ * ## Why the v0.19.2 hide-by-unset pattern caused a 403
+ *
+ * WordPress computes a page's hook suffix at TWO separate moments:
+ *
+ * 1. Registration time (inside add_submenu_page):
+ *    WP resolves the parent slug against $admin_page_hooks. If found, the hookname
+ *    becomes "{parent_key}_page_{slug}" (e.g. "prautoblogger_page_prautoblogger-dossier").
+ *
+ * 2. Request time (inside wp-admin/admin.php):
+ *    WP calls get_admin_page_parent() which scans $submenu for the slug. If not found
+ *    (because it was unset post-registration), it falls back to "admin_page_{slug}".
+ *
+ * When these two hooknames diverge, the render callback lives under name-A but WP
+ * dispatches to name-B -- no handler found -- wp_die(403).
+ *
+ * The fix: options.php-parent guarantees "admin_page_{slug}" at BOTH moments.
+ * No $submenu mutation is needed or permitted.
+ *
+ * ## Discriminator function: simulate_request_time_hookname
+ *
+ * Replicates get_admin_page_parent() + hookname derivation in wp-admin/admin.php.
+ * Returns different hooknames for hide-by-unset vs options.php-parent, making the
+ * 403 divergence mechanically verifiable in a unit test.
+ *
+ * Structural invariant tests (parent slug, URL shape, priority) live in
+ * DossierMenuRegistrationTest.
+ *
+ * @see DossierMenuRegistrationTest -- structural invariants + deep-link URLs + priority.
+ * @see ARCHITECTURE.md             -- §22b (hidden admin page convention).
+ * @see CONVENTIONS.md              -- §Hidden Admin Pages.
