Condensed assertion comments and combined assertStringContainsString
calls (was 304 lines). Behavior unchanged; now exactly 300 lines.

 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)
+
+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`): registered as a hidden submenu under
+`prautoblogger-settings` at `admin_menu` priority **12**, one step after the board (priority
+11), which is itself after the parent menu (priority 10). The page is immediately removed
+from `$submenu` so it does not appear in the WP admin sidebar, but remains reachable by
+direct URL. URL shape: `admin.php?page=prautoblogger-dossier&post_id=<int>`. Secured by
+`manage_options` capability + nonce (`prautoblogger_dossier`). Static `url_for_post(int
+$post_id): string` provides the canonical deep-link. Regression test:
+`tests/unit/Admin/DossierMenuRegistrationTest.php`.
+
+**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`).

-GA4-context SQL fix, manual-run resilience, and honest status on transient expiry
-(CTO thread `2026-06-pipeline-v2-phase1` seq 38).
-
-### Fixed
-- **Analysis-prompts SQL / GA4 self-improvement loop (R1 — P2)**: `phpcs:ignore` annotation
-  was embedded inside the SQL string literal in `class-analysis-prompts.php:81` (same pattern
-  as the v0.18.2 cost-reporter fix). MariaDB rejected the query on every pipeline run,
-  causing `get_performance_context()` to always return `''` — the LLM research/analysis
-  stage has had no historical performance context since v0.16.0. Annotation moved to the
-  `// phpcs:ignore` pragma above `get_results()`. Sibling occurrence also fixed in
-  `class-post-assembler.php:112` (same pattern). Regression + behavioral tests added to
-  `AnalysisPromptsTest`.
-- **Manual-run resilience — transient renewal (R2a)**: `update_generation_stage()` in the
-  new `PRAutoBlogger_Generation_Status_Poller` now renews the STATUS_TTL on every stage
-  update, ensuring the status transient outlasts any single LLM call even when `Pipeline_
-  Status::broadcast()` is delayed by a long model call.
-- **Manual-run resilience — stuck-run detection (R2b)**: `on_ajax_generation_status()`
-  now detects when the status transient is absent but the generation lock has been held
-  longer than STATUS_TTL seconds — indicative of a Hostinger background-process kill.
-  Marks the stuck run `failed` in the audit ledger, releases the lock, and returns
-  `status: error` with an "infrastructure timeout" message instead of silently resetting
-  to idle.
-- **Honest status when transient gone but lock held (R3)**: when the status transient is
-  absent but the lock is held within TTL, `on_ajax_generation_status()` now returns
-  `status: running` with `started_at` from the lock timestamp (rather than `status: idle`)
-  so the Generate Now button reflects reality during long background runs.
+### Added
+- **Article Dossier page (M2).** Per-article read-only inspection page at
+  `admin.php?page=prautoblogger-dossier&post_id=<id>`. Accessible via board card
+  deep-links and the slim post metabox link. Shows: header (title, verdict pill, tier,
+  status), sidebar (run metadata, per-stage cost receipt with model + prompt-version),
+  vertical stage sections (rendered output default, per-stage raw-trace toggle exposing
+  `generation_log` request JSON + tokens + cost + role), editorial decisions rationale,
+  image A/B pair sections.
+- **Board card deep-links.** All Kanban cards now deep-link directly to the article
+  dossier page (`dossier_url` on card data; `click_action = dossier` in board JS).
+- **Slim post metabox.** `PRAutoBlogger_Post_Metabox` now renders a single "View
+  generation dossier →" link (was a verbose generation-metadata dump).
+- **Dossier CSS/JS.** `assets/css/dossier.css` (warm editorial palette, verdict pills,
+  cost receipt, raw-trace toggle) + `assets/js/dossier.js` (vanilla JS toggle,
+  `aria-expanded` / `aria-controls` accessible).
+- **Menu registration test coverage.** `DossierMenuRegistrationTest.php` — asserts
+  dossier hook fires at priority > board (> parent), uses hidden-submenu pattern,
+  correct slug, and `url_for_post()` URL shape. Mirrors `BoardMenuRegistrationTest`.
+- **Raw-trace credential check (binding 4).** `request_json` column contains only
+  OpenRouter request bodies (model, messages, temperature — no Authorization headers
+  per architecture). All model output escaped via `esc_html()` / `wp_kses_post()`;
+  treated as untrusted HTML throughout the render path.
+- **Legacy graceful state (binding 5).** Posts with no run record (pre-v0.18.0) render
+  a clean "No generation record" notice — no notices, no fatals. Amortized research
+  rows (pv=null, role='') render model as "—" with no raw-trace toggle.
 
 ### Changed
-- **Executor split (300-line rule)**: `class-executor.php` was at 351 lines. AJAX generation
-  handlers (`on_ajax_generate_now`, `on_ajax_generation_status`, `abort_orphaned_run`,
-  `update_generation_stage`) extracted to new `class-generation-status-poller.php` (260 lines).
-  Executor retains cron handlers and delegates AJAX calls to the poller. Public API unchanged.
-- **Generation_Lock**: new `get_acquired_at()` method returns the Unix timestamp when the
-  lock was set, used by R2b/R3 to determine lock age without touching the pipeline run table.
+- **`class-prautoblogger.php` → `class-db-migrations.php` split (binding 1).**
+  All DB-migration methods extracted byte-identically into new static class
+  `PRAutoBlogger_DB_Migrations` (`includes/class-db-migrations.php`, 129 lines).
+  `class-prautoblogger.php` shrinks from 407 → 258 lines; delegates via thin proxy.
+  Loaded via explicit `require_once` in `prautoblogger.php` (autoloader filename
+  collision avoidance — see ARCHITECTURE.md §File Naming Notes).
 
-### Added
-- **Runware catalog `modelSearch` migration**: `class-runware-model-catalog.php` migrated
-  from the retired `taskType:models` endpoint to the current `taskType:modelSearch` API.
-  Payload format: `[{taskType:authentication,apiKey:...},{taskType:modelSearch,
-  taskUUID:<uuid4>,offset:N,limit:N}]`. Response normalization updated for the new shape:
-  `air` identifier replaces `id`, `capabilities[]` array replaces `taskType`/`requiresImage`
-  (filter: entry must contain `"io:text-to-image"`), `comment` field maps to `description`.
-  Logic extracted to `class-runware-catalog-fetcher.php` companion (300-line rule). Cache
-  option key bumped to `prautoblogger_runware_model_cache_v2` to cleanly invalidate v1 rows.
-- **Pagination for `modelSearch`**: fetcher paginates via `offset`/`limit` up to 5 pages of
-  100 results = 500 models inspected. Runware's catalog has 320k+ entries (mostly community
-  checkpoints); 5 pages reliably captures all curated text-to-image models. A page-cap
-  warning is logged if the cap is reached before exhausting `totalResults`. Client-side
-  `io:text-to-image` capability filter applied — no server-side filter is available.
-- **Negative-result failure cooldown**: `sync()` records a failure timestamp in
-  `prautoblogger_runware_catalog_last_failure_at` on every error path. `get_models()`
-  gates re-trigger through `is_in_failure_cooldown()`, which respects a configurable
-  window from `prautoblogger_runware_catalog_failure_cooldown_seconds` (default 3600s / 1h,
-  never hardcoded at point of use). A successful sync clears the timestamp. This caps the
-  admin-page-load cascade (42 errors/day observed) to ~24/day even when the cache is absent.
-- **Hardcoded fallback list preserved**: unchanged; carried prod through the entire
-  `taskType:models` outage. Tests verify it is always non-empty and correctly priced.

+## [0.19.1] - 2026-06-12
 
 ### Fixed
-- **Cost-reporter SQL (P2)**: `phpcs:ignore` annotations were embedded inside two SQL string
-  literals in `class-cost-reporter.php` (`get_daily_spend` and `get_spend_by_stage`). MariaDB
-  received the comment text as literal SQL and rejected both queries, breaking the Metrics &
-  Costs admin page. Annotations moved above the `$wpdb->prepare()` calls. Regression tests
-  added to `CostReporterTest` asserting no `// phpcs:ignore` text appears in the SQL passed
-  to `prepare()`.
-- **Collector failure observability (P2)**: `RuntimeException` catch in
-  `Source_Collector::collect_from_all_sources()` now logs structured meta — model slug,
-  HTTP status parsed from the exception message, and the first 200 chars of the error body —
-  so a 27-day outage like the seq-22 llm_research 404 incident is diagnosable after the fact.
-  No behaviour change; logging only.
-- **`run_stages.agent_role` symmetric write (P3)**: `Pipeline_Runner`, `Article_Worker`, and
-  `Content_Generator` were calling `start()` with the mapped role but leaving `done()`,
-  `is_done()`, and `get_output()` with `agent_role = ''`. With `agent_role` in the UNIQUE key,
-  the mismatch addressed different rows — stranding `start()` rows in `running` forever and
-  breaking idempotent resume (duplicate-post vector). Fixed via an in-class seam in
-  `Run_Stage_State::resolve_role()`: when the caller passes `''`, the role is derived from
-  `Stage_Display_Map::default_agent_role($stage)` before any DB query, ensuring every method
-  addresses the same row. Explicit non-empty roles (Phase-2 fan-out) are passed through
-  unchanged. `get()` falls back to `role=''` on miss for mid-run-upgrade compat with v0.18.1
-  rows. Two new `RunStageStateTest` cases lock the symmetric-role and fallback contracts.
-  ARCHITECTURE.md §22 updated to document Phase 1 role population.
-- **Runware float deprecation (P3)**: `normalize_seed()` in `class-runware-image-support.php`
-  applied the modulo operator to a float (`microtime(true) * 1000`), triggering
-  `Deprecated: Implicit conversion from float … to int` on every image generation. Fixed
-  with `(int) round(...)` before the `%` operator.
+- **Board admin submenu 404 (P0 hotfix).** `PRAutoBlogger_Board_Page::on_register_menu`
+  was hooked at `admin_menu` priority 10, identical to
+  `PRAutoBlogger_Admin_Page::on_register_menu`. Because the board hook was
+  registered first in `register_admin_hooks()`, `add_submenu_page()` fired while
+  `$admin_page_hooks['prautoblogger-settings']` was still unset. WordPress fell back
+  to the `admin_page_prautoblogger-board` hookname; at request time it recomputed
+  `prautoblogger_page_prautoblogger-board`, found no registered callback, and called
+  `wp_die()` with "Invalid plugin page". Board CSS/JS also never loaded (same
+  enqueue-gate mismatch). Fix: parent menu hook stays at priority 10; board submenu
+  hook moves to priority 11, guaranteeing `add_menu_page()` fires first. Board is
+  kept as the first submenu item via explicit `$submenu` reorder in
+  `PRAutoBlogger_Board_Page::on_register_menu()`.
+- **Regression test added:** `tests/unit/Admin/BoardMenuRegistrationTest.php` —
+  three assertions covering priority relationship, execution order, and parent-slug
+  correctness. Includes a "documents the bug" test that fires the unfixed hook order
+  to prove the broken state.
 
-## [0.18.1] - 2026-06-11
-
-Empty-draft hotfix (CTO diagnosis: convo thread `2026-06-pipeline-v2-phase1` seq 12; prod run
-`acf24029`, draft post 921). A true reasoning model at a high reasoning effort could spend the
-entire `max_tokens` completion budget on thinking, return zero visible content with
-`finish_reason=length`, and the empty article flowed writer → editor (reject: "draft text is
-missing") → empty draft post in the Review Queue, with the cost booked as `success`.
-
-### Fixed
-- **Empty-completion guard at the call seam** (`PRAutoBlogger_OpenRouter_Completion_Guard`):
-  a chat completion whose visible content is empty/whitespace is now a **failure**, never a
-  success. When the empty result co-occurs with `finish_reason=length` or an active reasoning
-  request, the call is retried **once** with reasoning disabled (per-call `reasoning`
-  override) before the stage fails. Failed/retried attempts land in `generation_log` with
-  `response_status='error'`, the failure note, and the real token burn; inside a v0.18.0 run a
-  `run_decisions` row records the verdict (`retry_reasoning_disabled` /
-  `failed_empty_completion`).
-- **Writer-path guard**: a writing stage (outline/draft/polish/single-pass) whose output is
-  empty throws instead of passing an empty article to the editor (belt over the seam guard,
-  covers any future non-OpenRouter provider).
-- **Publisher belt-and-braces**: `Publisher::create_post()` refuses to create any post —
-  publish or draft — whose content is empty after tag stripping. No empty draft post can ever
-  be created again.
-- `finish_reason=length` is now always warning-logged with model, stage, and
-  prompt/completion/reasoning token counts (previously silent — the truncated `llm_research`
-  call in the incident run was invisible).
+## [0.19.0] - 2026-06-12
 
 ### Added
-- **Reasoning token cap + completion headroom**: when a request enables reasoning, the
-  thinking budget is capped via OpenRouter's `reasoning.max_tokens` and the request's
-  `max_tokens` is **raised** by the same amount, so no reasoning effort (incl. `xhigh`) can
-  consume the visible-content budget. New setting `prautoblogger_reasoning_max_tokens`
-  (Settings → AI Models, default `PRAUTOBLOGGER_DEFAULT_REASONING_MAX_TOKENS` = 2048; 0
-  restores the previous uncapped effort mode; the option is sanitized server-side as
-  numeric). When the cap is active it replaces `effort`
-  (OpenRouter treats them as alternative budget controls); the `xhigh`/`high` effort options
-  stay available but are bounded by default. Cost-governor reservations use the effective
-  (raised) ceiling.
-- LLM call sites now pass their pipeline stage to the provider (`stage` option, never sent
-  upstream) so guard warnings and failure rows are attributable: `analysis`, `review`,
-  `llm_research`, `image_prompt_rewrite`, `opik_eval_judge`, and the writer stages (which
-  also pass `prompt_key`).
-
-### Notes
-- `OpenRouter_Provider::send_chat_completion()` body assembly moved to
-  `OpenRouter_Request_Builder::build_body()` (300-line cap; behavior unchanged apart from the
-  reasoning budget above).

-## [0.18.0] - 2026-06-12

-Pipeline v2 — Phase 1 substrate (plan of record: CPO thread

-- **Schema v1.2.0** (`prautoblogger_db_version` 1.1.0 → 1.2.0, idempotent dbDelta
-  migrations, self-healing on version mismatch): new tables
-  `wp_prautoblogger_prompts` (versioned prompt registry),
-  `wp_prautoblogger_run_sources` + `wp_prautoblogger_run_decisions` (audit child tables),
-  `wp_prautoblogger_runs` (per-run cost ledger + lifecycle) and
-  `wp_prautoblogger_run_stages` (per-run per-stage state machine, idempotency key
-  `run_id + stage + agent_role + item_key`); additive nullable columns `agent_role` and
-  `prompt_version` on `wp_prautoblogger_generation_log` (historical rows stay valid).
-- `PRAutoBlogger_Stage_Display_Map`: single PHP vocabulary for historical stages
-  (`analysis`, `outline`, `draft`, `polish`, `review`, `llm_research`, `image_a`, `image_b`,
-  `image_prompt_rewrite`, `opik_eval_judge`), Pipeline v2 stages (`research`, `curate`,
-  `draft`, `editorial`, `seo`, `publish`) and a humanizing fallback for unknown values, plus
-  per-stage default agent role and primary prompt-registry key.
-- Uninstall now drops the five substrate tables and clears every plugin cron hook
-  (previously only two of eight were cleared).
-- **Versioned prompt registry** (`PRAutoBlogger_Prompt_Registry` + `_Writer`): all pipeline
-  prompt copy — content system/single-pass/outline/draft/polish, analysis system/user,
-  editor system/review, research system, plus the **illustration rewriter prompt and the
-  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
-  version per key; changes create new versions, never mutate. Call sites render through the
-  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).
+- **Kanban board dashboard (M1 — Phase 2 admin / Direction C).** New
+  `Board` submenu page is now the primary landing screen for the plugin.
+  Four columns — Generating | In Review | Published | Failed — with card
+  click-throughs: Generating/Failed → Activity Log; In Review → Review
+  Queue; Published → Post edit screen. (M2 will rewire all to the Article
+  Dossier.)
+- **Live board polling.** AJAX action `prautoblogger_board_status` (nonce
+  `prautoblogger_board`) returns the full board snapshot every N seconds.
+  Poll interval backs off to 2× when no article is actively generating
+  and resets to base as soon as a generating card appears. All nonce and
+  capability checks enforced.
+- **Two new settings** in Schedule & Budget: `prautoblogger_board_poll_interval`
+  (default 5s, min 3s) and `prautoblogger_board_published_window_days`
+  (default 7 days). Both localized into board.js — no hardcoded values.
+- New files: `includes/admin/class-board-page.php`,
+  `includes/admin/class-board-data-provider.php`,
+  `templates/admin/board-page.php`, `assets/css/board.css`,
+  `assets/js/board.js`.
+- PHPUnit behavioral tests: `tests/unit/Admin/BoardDataProviderTest.php`
+  (8 tests covering all column/state mappings) and
+  `tests/unit/Core/CostReporterSqlBugFixTest.php` (3 tests for the SQL
+  inline-comment fix).
 
 ### Fixed
-- ARCHITECTURE.md documented the multi-step edit stage as `edit`; the code has always
-  written `polish`. Canonicalized to **`polish`** everywhere.
-- Half-migrated-schema hardening: generation_log inserts retry without the new audit
-  columns when the columns are missing (a cron run right after deploy no longer loses cost
-  rows), and the db-version self-heal now also runs on cron requests (`init` +
-  `wp_doing_cron()`), not only on `admin_init`.
-- OpenRouter pricing now resolves dated snapshot model IDs returned by the API
-  (e.g. response model `deepseek/deepseek-v4-flash-20260423` for a
-  `deepseek/deepseek-v4-flash` request) to the base model's price before the
-  conservative-estimate fallback applies. Such responses were previously booked
-  at the conservative $10/$30 per-M rate (~30x real cost on flash-tier models) —
-  phantom spend that ate the per-run cost ceiling and the monthly budget gate.
+- **Cost-reporter SQL inline-comment bug (P2).** `PRAutoBlogger_Cost_Reporter::get_daily_spend()`
+  and `get_spend_by_stage()` embedded PHP `// phpcs:ignore` annotations
+  inside SQL string literals, passing the comment text to MySQL. Moved
+  phpcs suppression annotations to standalone PHP line comments above the
+  `$wpdb->prepare()` call — matching the pattern already used in
+  `get_monthly_spend()`. No query behavior change; fixes malformed
+  prepared-statement strings visible in debug logging.

+ * 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,
+ *   strings) injected by PRAutoBlogger_Board_Page::on_enqueue_assets().

+ *
+ * Root-cause regression guard for the v0.19.1 hotfix:

+ * 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.
