fix: rewrite board-data-provider without null bytes (bash-mount artifact)

The previous commit had class-board-data-provider.php written via the
Windows Write tool which pads the file with CIFS block-aligned null bytes.
Rewrite from Python string literal in /tmp to produce a clean UTF-8 file
with no null bytes.

 ### #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.

+
+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 first so it appears before Settings in the nav.
+`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.

 ## 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.

-  (previously only two of eight were cleared).
+- New files: `includes/admin/class-board-page.php`,
-- **Versioned prompt registry** (`PRAutoBlogger_Prompt_Registry` + `_Writer`): all pipeline
+  `includes/admin/class-board-data-provider.php`,
-  prompt copy — content system/single-pass/outline/draft/polish, analysis system/user,

-  registry with a **byte-identical in-code fallback** when the table is missing/empty
+  inline-comment fix).
-  (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
-- ARCHITECTURE.md documented the multi-step edit stage as `edit`; the code has always
+- **Cost-reporter SQL inline-comment bug (P2).** `PRAutoBlogger_Cost_Reporter::get_daily_spend()`
-  written `polish`. Canonicalized to **`polish`** everywhere.
+  and `get_spend_by_stage()` embedded PHP `// phpcs:ignore` annotations
-- Half-migrated-schema hardening: generation_log inserts retry without the new audit
+  inside SQL string literals, passing the comment text to MySQL. Moved
-  columns when the columns are missing (a cron run right after deploy no longer loses cost
+  phpcs suppression annotations to standalone PHP line comments above the
-  rows), and the db-version self-heal now also runs on cron requests (`init` +
+  `$wpdb->prepare()` call — matching the pattern already used in
-  `wp_doing_cron()`), not only on `admin_init`.
+  `get_monthly_spend()`. No query behavior change; fixes malformed
-- OpenRouter pricing now resolves dated snapshot model IDs returned by the API
+  prepared-statement strings visible in debug logging.
-  (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.

+ *
+ * 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,

+ *
+ * R2/R3 resilience (v0.18.3):
+ *   - R2(a): on_ajax_generate_now() renews the transient with the
+ *     full STATUS_TTL on every stage update via update_generation_stage().
+ *   - R2(b): on_ajax_generation_status() detects lock-held-but-transient-gone
+ *     when the lock has been held > STATUS_TTL seconds (Hostinger background-
+ *     process death); marks the stuck run failed + surfaces a human-readable
+ *     "infrastructure timeout" message for the Activity Log.
+ *   - R3: on_ajax_generation_status() returns status:running (with
+ *     started_at) when the transient is absent but the lock IS held and
+ *     within TTL — so the button reflects reality during long runs rather
+ *     than silently resetting to idle.

+ *       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()
