fix(ci): yoda condition + un-shadow capability-cache test expectations

- class-image-composer.php: swap the fingerprint comparison operands
  (WordPress.PHP.YodaConditions flagged the parenthesized null-coalesce
  expression on the right-hand side).
- ImageComposerTest: the two capability-cache tests asserted
  update_option calls via Functions\expect(), which the setUp
  Functions\when() stub shadows (Mockery dispatches the call to the
  first matching expectation), so the with()-matcher saw 0 calls once
  the CI runner's real imagick made the probe path live. Capture calls
  with a when() alias instead (the suite's house pattern) and assert on
  the captured writes - including autoload=false and the rewritten
  fingerprint. The matching-fingerprint test now genuinely asserts
  zero writes instead of a trivially-satisfied never().

No composer behavior change beyond the operand swap.

+## Opik LLM Observability (Optional)
+
+**Status:** Wave 1 (v0.12.0) — tracing skeleton. Wave 2 (future) — eval harness with frozen-dataset regression testing.
+
+Opik is a cloud-hosted LLM observability platform (Comet) providing:
+- **Per-call tracing:** Every OpenRouter call generates a span with model, tokens, latency metadata.
+- **Trace grouping:** One trace per article generation bundles all spans (draft, QA, image prompt).
+- **Prompt versioning:** Foundation for Wave 2 — compare new prompt revisions against a frozen reference dataset using LLM-as-judge scoring on rubric axes (factual accuracy, style match, hallucination risk).
+
+**Architecture:**
+- **Feature flag:** `prautoblogger_opik_enabled` (WP option, default off). When false, zero network traffic to Opik.
+- **Credentials:** API key and workspace from PHP constants `PRAUTOBLOGGER_OPIK_API_KEY`, `PRAUTOBLOGGER_OPIK_WORKSPACE` (defined in wp-config.php). Never stored in DB.
+- **Span lifecycle:** 
+  1. `Opik_Trace_Context::init_trace()` generates UUID at article-worker start.
+  2. Each LLM call wraps with `start_span()` → LLM request → `end_span()` with tokens + response.
+  3. `finalize_trace()` + `Opik_Span_Queue::enqueue()` accumulates trace + spans for async dispatch.
+  4. `prautoblogger_opik_dispatch` cron action batches spans/traces (max 100 per POST) to `/v1/private/spans/batch`, `/v1/private/traces/batch`.
+- **Retry logic:** Exponential backoff (2s, 4s, 8s) on 5xx errors; permanent abort on 4xx; dropped after 3 attempts per item.
+- **Queue:** WP options-backed; max 1000 items; 12-hour TTL; persists across page reloads for truly async dispatch.
+
+**Call sites instrumented (Wave 1):**
+- Draft generation (single-pass or multi-step outline/draft/polish).
+- Editorial review (chief editor LLM call).
+- Image prompt generation (deferred; file at 314 LOC, over limit).
+
+**Cost & Performance:**
+- Opik free tier: 25k spans/month. Estimated current usage ~4.2k/month (20 posts/day × 7 calls × 30 days). Headroom to 5× growth.
+- Impact on article generation: async dispatch, zero blocking latency overhead.
+- Wave 2 (eval harness): adds LLM-as-judge calls (~$14/month at Haiku pricing, assuming 2 eval runs/week).
+
+**Code structure:**
+```
+includes/services/opik/
+  class-opik-client.php            — REST client (auth, retry, batch POSTs)
+  class-opik-trace-context.php     — per-request trace state singleton
+  class-opik-span-queue.php        — WP options-backed async queue
+  class-opik-dispatcher.php        — cron handler, batch dispatch
+
+includes/admin/
+  class-opik-settings.php          — admin UI (toggle, project name, status)

+### #20: Editorial illustration prompt + style-template setting (v0.16.0, May 2026)
+
+Commit 1 of the in-plugin editorial image pipeline (brief `docs/proposals/2026-05-29-image-pipeline-in-plugin-brief.md`). The image style pivots from a single-panel newspaper comic to a **text-free editorial scientific illustration**. Two changes ship here; the deterministic PHP composer is a later commit.
+
+1. **Prompt structure.** `Image_Prompt_Builder::REWRITER_SYSTEM_PROMPT` now asks the rewriter LLM for a concise 1-2 sentence topic/mechanism summary (one concrete centered focal subject, no text/people-as-gag/logos) as the SCENE, keeping the short CAPTION line for the unchanged HTML-caption-below-image path. The scene/caption parsing contract (`Image_Scene_Parser`) is unchanged.
+2. **Template substitution.** The old `trim($scene . ' ' . $style_suffix)` concat is replaced by `PRAutoBlogger_Image_Template_Filler::fill($scene)` in all three entry points (`build_article_prompt`, `build_source_prompt`, `build_fallback_prompt`). The filler resolves the active template (admin override → default), strips control chars and clamps the summary length (brief A5), then substitutes the single `{{ topic_summary }}` token. Degradation (brief A5/A6): if the template lacks exactly one token it appends the summary and logs a warning; if the summary is empty it emits the style-only prompt — a blank or token-only prompt is never sent to the provider.
+3. **Setting.** New textarea `prautoblogger_image_style_template` (default `PRAUTOBLOGGER_DEFAULT_IMAGE_STYLE_TEMPLATE`) replaces the Style Suffix field. On save it is sanitised with `sanitize_textarea_field` and validated to contain exactly one token (`Image_Template_Filler::sanitize_for_save`). The old `prautoblogger_image_style_suffix` is mirrored to `..._deprecated` for one cycle and not deleted (one-time migration `prautoblogger_migrated_style_template_v0160`).
+
+Provider/model are unchanged — only the prompt text changes, so production keeps emitting via Runware FLUX.1 schnell but now produces text-free editorial base images.
+
+### #21: Deterministic PHP image composer with capability ladder (v0.17.0, Jun 2026)
+
+Commit 2 (and final scope) of the in-plugin editorial image pipeline (#20). Small diffusion
+models cannot render clean text (2026-04-21 A/B finding), so base images are text-free —
+but the one image that travels *without* its HTML caption is the social/OG share image.
+A **deterministic local composer** (`PRAutoBlogger_Image_Composer` behind
+`PRAutoBlogger_Image_Composer_Interface`) now runs between provider bytes and sideload:
+
+1. **Variants.** Image A → corner-marked featured (1200×632) + branded OG (1200×630, teal
+   band, brand mark, baked caption in Poppins SemiBold) + square card (1080×1080: full base
+   downscaled into a 1080×569 top slice — no upscaling — cream caption panel in Poppins
+   Bold, teal footer with the horizontal reverse lockup). Image B → corner mark only. The
+   variant set is config-driven (`prautoblogger_image_compose_variants`, default `og,square`;
+   square has no consumer yet — CEO wants it rendered + stored now). Variants are
+   meta-linked via `_prautoblogger_image_role`, `_prautoblogger_base_attachment_id`,
+   `_prautoblogger_og_image_id`, `_prautoblogger_square_image_id`. The og key is **frozen**:
+   the rebuilt SEO stage (pipeline-redesign §4.8) emits `og:image` from it.
+2. **Capability ladder, never fatal.** Imagick is probed once (PNG format + TTF annotate
+   smoke test) and cached in `prautoblogger_image_compose_capability`, fingerprinted by
+   PHP version + imagick/gd presence so host flips (hPanel/cagefs — it has happened)
+   auto-invalidate the cache. Rungs: imagick → `wp_get_image_editor()` resize-only
+   (unbranded, square skipped because it would upscale) → pass-through. Every render is
+   try/caught; degradation logs one WARNING per run; the publish always proceeds with the
+   editable HTML caption intact. Test/ops override: `prautoblogger_image_compose_capability`
+   filter.
+3. **Determinism.** Bundled OFL fonts (no system-font queries), vendored brand PNGs (no
+   runtime SVG delegate variance), `stripImage()` + PNG date/time chunks excluded + fixed
+   compression → byte-stable output **per environment** (not across ImageMagick versions).
+   Composition is local CPU, $0, logged as a duration-only stage on the `image_composer`
+   channel — no cost-tracker rows.
+4. **Layout tuning.** Geometry/opacity are constants in
+   `PRAutoBlogger_Image_Composer_Layout::defaults()` behind the
+   `prautoblogger_image_compose_layout` filter — deliberately not settings; promote only if
+   the CEO asks to tune them. The caption is hard-clamped (word-boundary wrap + ellipsis,
+   multibyte-safe) even though the rewriter LLM is already constrained to <15 words.
+
 ### #17: Runware as default image backend (v0.9.0, Apr 2026)
 
 After a comic-style A/B round in Apr 2026, FLUX.1 schnell via Runware was chosen as the default image backend. Cost is ~$0.0006/image vs ~$0.039/image for Gemini 2.5 Flash Image via OpenRouter (≈65× cheaper), and the looser schnell fidelity reads as editorial-cartoon style — a feature, not a bug, for our single-panel comic aesthetic. FLUX.1 dev (~$0.02/image, 28 steps) remains available as an opt-in for higher-fidelity runs. The Runware layer mirrors the OpenRouter split (interface + provider + support + pricing + batch), all under the 300-line cap. The batch class dispatches `imageInference` POSTs via `curl_multi_init/exec/select` — wall-clock time for the A/B pair drops to ≈ the slowest single image. A v0.9.0 one-time migration (`prautoblogger_migrated_default_image_v090`) flips sites still on the legacy default; explicit user selections are preserved. Cloudflare Workers AI was removed as an image provider in v0.10.0 (see ADR #16 note below).

+### #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.

+## [0.17.0] - 2026-06-11
+
+### Added
+- **Deterministic PHP image composer (Commit 2 of the in-plugin editorial image
+  pipeline).** Every generated image now passes through a local, $0,
+  deterministic composer between the provider's bytes and the media sideloader.
+  Image A yields a corner-marked featured image (1200×632) plus a branded
+  **OG/social variant** (1200×630, teal band, brand mark, baked editorial
+  caption in Poppins SemiBold) and a **square card variant** (1080×1080, image
+  slice + cream caption panel in Poppins Bold + teal footer with the horizontal
+  lockup). Image B gets the corner mark only. Variants are sideloaded with a
+  role filename suffix and meta-linked: attachment meta
+  `_prautoblogger_image_role` + `_prautoblogger_base_attachment_id`, post meta
+  `_prautoblogger_og_image_id` + `_prautoblogger_square_image_id` (the rebuilt
+  SEO stage will emit `og:image` from the frozen og key).
+- **Capability ladder with cached probe.** Imagick (full compositing) →
+  `wp_get_image_editor()` GD path (resize-only, unbranded, single WARNING) →
+  pass-through (single WARNING). The probe result is cached in
+  `prautoblogger_image_compose_capability`, fingerprinted by PHP version +
+  imagick/gd presence so it auto-invalidates when the host changes. Override
+  filter: `prautoblogger_image_compose_capability`. Composition failure can
+  never block a publish (per-render try/catch + pipeline safety net).
+- New Images settings: `prautoblogger_image_compose_enabled` (default on),
+  `prautoblogger_image_compose_variants` (default `og,square`),
+  `prautoblogger_image_featured_mark_enabled` (default on). Geometry ships as
+  layout-class constants behind the `prautoblogger_image_compose_layout`
+  filter. All keys keep the `prautoblogger_`/`_prautoblogger_` prefixes, so
+  the existing uninstall prefix-sweep purges them (no uninstall.php changes).
+- Vendored brand rasters (`assets/brand/`, from peptide-repo-brand SVG masters)
+  and bundled OFL fonts (`assets/fonts/`: Poppins Bold + Poppins SemiBold +
+  OFL.txt) — no system-font or runtime-SVG dependency, byte-stable output per
+  environment (metadata stripped, PNG date/time chunks excluded).
+
+### Fixed
+- Featured/Image B **alt text is now the editorial caption** instead of the
+  generation model name (`sideload_and_log()` passed the model as `$alt_text`,
+  contradicting the sideloader docblock). The model keeps persisting in
+  `_prautoblogger_image_model`.
+
+### Changed
+- `PRAutoBlogger_Image_Media_Sideloader::sideload_image()` /
+  `generate_filename()` accept an optional filename role suffix
+  (back-compat default `''`).
+- `PRAutoBlogger_Image_Pipeline` delegates sideload/cost-log, caption
+  prepending, and variant persistence to the new
+  `PRAutoBlogger_Image_Attacher` (300-line compliance); also declares the
+  previously-dynamic `$trace_context` property (PHP 8.2 deprecation).
+
+## [0.16.0] - 2026-05-29
+
+### Changed
+- **Editorial image prompt (Commit 1 of the in-plugin editorial image pipeline).**
+  The image style pivots from a single-panel newspaper comic to a text-free
+  editorial scientific illustration. The rewriter LLM now emits a concise
+  1-2 sentence topic/mechanism summary as the SCENE (one centered focal
+  subject, no text/people-as-gag/logos), keeping the short CAPTION line for the
+  unchanged HTML-caption-below-image behavior. The scene/caption parsing
+  contract is unchanged. Provider/model are unchanged — production keeps
+  generating via Runware FLUX.1 schnell but now produces text-free editorial
+  base images. See `docs/proposals/2026-05-29-image-pipeline-in-plugin-brief.md`.
+- The prompt builder now substitutes the rewriter scene into an editable style
+  template's `{{ topic_summary }}` slot via the new
+  `PRAutoBlogger_Image_Template_Filler`, replacing the old
+  `scene + style suffix` concatenation, across all three entry points
+  (`build_article_prompt`, `build_source_prompt`, `build_fallback_prompt`).
+  Before substitution the scene is stripped of control characters and
+  length-clamped (brief A5). If the template lacks exactly one token the
+  summary is appended and a warning logged; if the summary is empty the
+  style-only prompt is emitted — a blank or token-only prompt is never sent to
+  the provider (brief A5/A6).
+
+### Added
+- New setting **Style Template** (`prautoblogger_image_style_template`,
+  textarea) replacing the Style Suffix field. Default =
+  `PRAUTOBLOGGER_DEFAULT_IMAGE_STYLE_TEMPLATE` (the editorial template). On save
+  it is validated to contain exactly one `{{ topic_summary }}` token; an invalid
+  template keeps the previous value and surfaces a settings error.
+
+### Deprecated
+- `prautoblogger_image_style_suffix` is deprecated and no longer read by the
+  prompt builder. A one-time migration (`prautoblogger_migrated_style_template_v0160`)
+  mirrors its value to `prautoblogger_image_style_suffix_deprecated` for one
+  version cycle and seeds the new template default. The old option is NOT
+  deleted this cycle.
+
+## [0.15.1] - 2026-05-14
+
+### Fixed
+- Cost preview in AI Models settings tab no longer prints a WordPress database
+  error notice; query now uses canonical column names (`prompt_tokens`,
+  `completion_tokens`, `created_at`). Bug present since v0.11.0 (2026-04-23).
+
+## [0.14.0] - 2026-04-26
+## [0.15.0] - 2026-04-26
+
+### Added
+- **Live Runware Model Catalog Sync**: New `class-runware-model-catalog.php`
+  fetches the live Runware model list via their `/v1` endpoint (task-based API),
+  filters to `taskType=imageInference` (text-to-image only, excluding inpainting),
+  normalizes to the Image_Model_Registry shape, and caches in `prautoblogger_runware_model_cache`
+  with a 24-hour TTL. Fixes the pattern from v0.13.8 and v0.14.0 where the
+  hardcoded Runware model list was a maintenance burden and gaps (missing models,
+  wrong prices) went unnoticed until customer images generation broke.
+- Daily WP-Cron sync (`prautoblogger_sync_runware_models`) scheduled on activation
+  and unscheduled on deactivation.
+- On-demand "Sync now" AJAX button in PRAdmin (Images settings section) with
+  nonce protection and `manage_options` cap check. Refreshes model count and
+  last-synced timestamp in the UI without full page reload.
+- Smart caching + fallback strategy: if cache is < 24h old, use it; if stale,
+  trigger a sync; if sync fails, use the last-known-good cache; if no cache,
+  fall back to hardcoded list (never returns empty array).
+- Pricing merge: Runware API may not expose per-image cost. The catalog pulls
+  costs from `class-runware-image-pricing.php::COST_PER_IMAGE` on every sync,
+  ensuring pricing data is always authoritative and up-to-date.
+- Unit tests for `PRAutoBlogger_Runware_Model_Catalog`: sync success/failure,
+  fallback on API unreachable, stale cache behavior, cost merge logic.
+- `class-image-model-registry.php` refactored: `get_models()` now delegates to
+  the catalog for Runware models + static OpenRouter list. Extracted fallback
+  lists into private `get_runware_fallback_models()` and `get_openrouter_models()`
+  for clarity.
+
+### Fixed
+- Silent model list gaps no longer possible: Runware no longer depends on manual
+  model list maintenance in the pricing class. The live catalog is the source of
+  truth; pricing is merged in on every sync.
+
+### Changed
+- `class-image-model-registry.php`: `get_models()` is now a thin wrapper around
+  the catalog + OpenRouter static list. Breaking change: callers that expect a
+  specific static list should note the new dynamic Runware side.
+
+
+### Fixed
+- Runware image generation now correctly uses the admin-selected model instead
+  of silently falling back to FLUX.1 schnell (runware:100@1) for all non-schnell
+  and non-dev selections. Root cause: `class-runware-image-pricing.php` only
+  had 2 models in its `COST_PER_IMAGE` whitelist (schnell + dev), but the
+  image model registry was expanded to 15 Runware models in v0.13.8 without a
+  matching update to the pricing class. Any model ID not in the whitelist caused
+  `resolve_model()` to fall back to schnell, so every Stable Diffusion, FLUX.2,
+  HiDream, TwinFlow, Z-Image, Qwen-Image, Krea, and GLM-Image selection was
+  silently downgraded.
+- Added all 15 Runware model IDs to `COST_PER_IMAGE` and `DEFAULT_STEPS` with
+  correct per-image costs and step counts sourced from runware.ai/pricing (April 2026).
+- Added `@see` cross-reference to `class-image-model-registry.php` in pricing
+  class docblock to prevent future drift.
+
+## [0.13.9] - 2026-04-26
+
+### Fixed
+- Model picker sort by price now works correctly for image models — previously
+  \`applySort\` always read \`input_price_per_m\` (undefined on image models),
+  so every image had an effective price of 0 and price sort was a no-op.
+  Fix: detect image models via \`cost_per_image\` and use that field instead.
+
+## [0.13.8] - 2026-04-26
+
+### Added
+- Image model picker expanded from 7 to 21 models
+- New Runware text-to-image models: Stable Diffusion 3, HiDream-I1 Full/Dev/Fast,
+  FLUX.1 Krea [dev], Qwen-Image, FLUX.2 [dev], FLUX.2 [klein] 9B, FLUX.2 [klein] 4B,
+  GLM-Image, Z-Image, Z-Image-Turbo, TwinFlow Z-Image-Turbo

+## [0.13.7] - 2026-04-24
+
+### Fixed
+- Posts list column layout: title was set to 35% which, combined with 3 fixed-width PRAB columns, left ~50px for every remaining column (Author, Categories, Tags, Date all word-wrapping). Replaced with a balanced budget: title 22%, author 6%, categories 7%, tags 9%, date 8%, PRAB columns 85/85/50px, Peptide Topics 75px.
+
+## [0.13.6] - 2026-04-24
+
+### Fixed
+- Peptide Topics column still rendering vertically: WordPress posts table uses `table-layout: fixed` which ignores `min-width` entirely. Changed to explicit `width: 80px` which is respected under fixed-layout tables.
+
+## [0.13.5] - 2026-04-24
+
+### Fixed
+- Cost column in Posts list was always showing $0.00: a PHP `// phpcs:ignore` comment was embedded inside the SQL string literal, causing a MariaDB syntax error on every query. Moved comment above the `prepare()` call.
+- Peptide Topics column header in Posts list was being squeezed to near-zero width by the fixed-width PRAB columns. Added `min-width: 80px` to `.column-taxonomy-peptide_topic`.
+
+## [0.13.4] - 2026-04-24
+
+### Fixed
+- Model picker price column now consistently right-aligned. Root cause: price and description were siblings inside .ab-mp-row-meta, with description first and variable-length — this shifted price left/right per row. Fix: moved price to last position with flex-shrink: 0 so its right edge is always pinned to the row edge; capped description at max-width 200px with ellipsis; swapped column headers to match new DOM order.
+
+## [0.13.3] - 2026-04-24
+
+### Fixed
+- Price column header now right-aligned with `min-width: 90px` to match data cells — header and prices now track the same column edge.
+
+## [0.13.2] - 2026-04-24
+
+### Changed
+- Model picker: added sortable column headers (Model, Price, Context); clicking a header sorts the list ascending/descending; active column highlighted with sort arrow; sort preference persists while the picker is open.

+## [0.12.3] — 2026-04-24
+## [0.13.1] - 2026-04-24
+
+### Fixed
+- Model picker price column now right-aligned with a minimum width so values like `$0.0006/image` and `$0.0800/image` stack cleanly instead of floating at uneven offsets.
+
+## [0.13.0] - 2026-04-24
+
+### Added
+- **Wave 2 Eval Harness**: Complete evaluation framework for PRAutoBlogger output quality
+  - Frozen eval dataset (`eval/dataset.json`) with 20 curated peptide topics
+  - LLM-as-judge scorer (`class-opik-eval-scorer.php`) using Gemini Flash 1.5
+  - Eval runner orchestrator (`class-opik-eval-runner.php`) with Opik experiment support
+  - WP-CLI command: `wp prautoblogger opik:eval [--limit=<n>] [--dry-run]`
+  - Image pipeline instrumentation: Opik span wrapping for `image_prompt_rewrite` step
+- **Image Prompt Builder Refactor**: Extracted scene/caption parsing into `PRAutoBlogger_Image_Scene_Parser`
+  - Three static methods: `parse_scene_and_caption()`, `extract_first_paragraph()`, `synthesize_visual_concepts_fallback()`
+  - Cleaner separation of concerns; builder now ~255 lines (was 331)
+- **Content Generator Eval Mode**: Added `$eval_mode` parameter to suppress publishing and image generation side effects
+- **Trace Context Integration**: Optional trace instrumentation in `PRAutoBlogger_Image_Prompt_Builder` constructor
+
+### Changed
+- `PRAutoBlogger_Image_Prompt_Builder` constructor now accepts optional `PRAutoBlogger_Opik_Trace_Context` parameter
+- `PRAutoBlogger_Image_Pipeline` constructor passes trace context through to prompt builder
+- Image prompt rewrite LLM calls now emit Opik spans when trace context is available
+
+### Fixed
+- Image prompt builder now properly delegates to static parser methods
+
+
+### Fixed
+- **Opik autoloader gap** — `class-autoloader.php` listed `services/` as a scan directory but not `services/opik/`, where all four Opik classes live (`Opik_Client`, `Opik_Trace_Context`, `Opik_Span_Queue`, `Opik_Dispatcher`). Composer's classmap (used in PHPUnit) covers `includes/` recursively so tests passed, but the WordPress runtime autoloader would fatal on first Opik class reference in production. Added `services/opik/` to the scan list.
+
+
+## [0.12.2] — 2026-04-24
+
+### Fixed
+- **Image style suffix empty-string bypass** — `get_option()` for `prautoblogger_image_style_suffix` only returns the default constant when the key is absent from `wp_options`; an empty string stored in the DB returns `''`, bypassing fallback entirely. Root cause of post #675 rendering photorealistically instead of as a newspaper comic. Fixed all three call sites in `class-image-prompt-builder.php` (lines 85, 107, 272) by extracting a private helper `get_style_suffix()` that treats both absent AND empty string as "use default".
+
+- **Image cost logged under wrong run_id** — `class-image-pipeline.php` created a fresh cost tracker when invoked without an argument, so image costs were logged under a different `run_id` than the article's other stages. Cost breakdowns aggregating by `run_id` silently excluded the image line item. Fixed by threading the article worker's cost tracker through `PRAutoBlogger_Publisher` and `PRAutoBlogger_Post_Assembler::attach_generated_images()` to the image pipeline constructor. Image costs now share the same `run_id` as analysis, draft, review, and llm_research stages.
+
+
+## [0.12.1] — 2026-04-23
+
+### Fixed
+- **Opik UUID v7 bug** — `PRAutoBlogger_Opik_Trace_Context` was generating trace and
+  span IDs with `wp_generate_uuid4()` (UUID v4). Opik's REST API requires UUID v7 and
+  rejects v4 with HTTP 400 "Trace id must be a version 7 UUID". Added a private static
+  `generate_uuid7()` method using `microtime()` + `random_bytes()` and replaced both
+  call sites. All trace and span submissions now succeed.
+
+## [0.12.0] — 2026-04-23
+
+### Added
+- **Opik LLM observability integration (Wave 1: tracing skeleton).** Cloud-hosted observability via Comet Opik for detailed per-call tracing and prompt-version regression testing. Captured via async fire-and-forget dispatch to avoid blocking article generation.
+
+- **Opik REST client.** Minimal HTTP client (no third-party SDK) with exponential backoff retry, batch endpoints, and credential isolation (API key from wp-config.php constants, never in DB).
+
+- **Per-request trace context singleton.** Holds trace ID + span stack for one article generation. UUID threading across draft generation, editorial review, and image prompt generation.
+
+- **Async span/trace queue.** WP options-backed queue with TTL expiry (12 hours) and max depth (1000 items). Drained by cron dispatcher with per-batch retry logic.
+
+- **Cron dispatcher.** `prautoblogger_opik_dispatch` action scheduled via `wp_schedule_single_event()` drains queue in batches of up to 100 spans.
+
+- **Opik admin settings section.** Toggle to enable/disable tracing (default off), project name field, opt-in full-prompt capture, read-only status display (API key configured, last dispatch, queue depth).
+
+- **Span instrumentation at four LLM call sites:** single-pass article generation, outline/draft/polish stages (multi-step), and editorial review. Each span captures model name, provider, usage tokens.
+
+- **Comprehensive unit test suite.** 4 test files covering client (auth, retry, batch limits), trace context (UUID generation, span stacking), queue (enqueue/dequeue, expiry, reenqueue), and dispatcher (batch POST, separation of traces vs. spans).
+
+### Changed
+- **class-article-worker.php:** Initializes Opik trace context at generation start, enqueues finalized trace + spans at end if feature enabled.
+
+- **class-content-generator.php:** Wraps single-pass and multi-step stages (outline, draft, polish) with Opik spans capturing token usage.
+
+- **class-chief-editor.php:** Wraps editorial review LLM call with Opik span.
+
+### Notes
+- **Feature-flag default OFF.** Zero network traffic to Opik unless `prautoblogger_opik_enabled` option is true AND API credentials are defined in wp-config.php.
+- **Image prompt generation instrumentation deferred.** File already at 314 LOC (over 300-line rule); can be instrumented in Wave 2 without modifying existing code.
+- **Wave 2 holds eval harness.** CLI command for frozen-dataset regression testing with LLM-as-judge scoring (separate thread after v0.12.0 ships and is live-tested).
+
+## [0.11.0] — 2026-04-23
+
+### Added
+- **OpenRouter model picker for text models.** Admin-facing dropdown field type (`model_select`) with searchable list, capability filtering, and estimated cost preview. Replaces free-text model slug inputs on the three text model settings (analysis, writing, editor). Includes daily cron refresh of the OpenRouter registry cache and manual "Refresh Model List" button on the AI Models tab.
+
+- **Cost preview in model picker.** Shows estimated cost per generation based on historical token usage for the 30 days prior. Maps each setting to its constituent pipeline stages (writing model = outline + draft + polish).
+
+- **AJAX refresh endpoint** (`prautoblogger_refresh_models`) for manual model registry refresh with nonce + capability gating (`manage_options`).
+
+- **New public method on Cost Tracker:** `get_avg_tokens_for_stages(array $stages, int $days = 30): array` returns average input/output token counts for a stage list, used by cost preview.
+
+### Changed
+- **AI Models tab now renders a "Refresh Model List" button** next to the panel title. Triggers `prautoblogger_refresh_models` AJAX endpoint.
+
+## [0.10.1] — 2026-04-23
+
+### Fixed
+- **PHPCS: closed the last 26 WordPress-Core residuals** (15 short ternaries rewritten, 11 targeted ignores on false-positive ternary-with-prepare in ideas-browser + logger).
+
+- **Tests: OpenRouterImageProviderTest now round-trips through real Encryption class.**
+  setUp was using a dead `eval()` mock that never installed because the real `PRAutoBlogger_Encryption`
+  class was autoloaded first. Tests now call `PRAutoBlogger_Encryption::encrypt()` directly,
+  leveraging the BaseTestCase-stubbed `wp_salt()` for deterministic round-trip decryption.
+  Fixes both `test_generate_image_success` and `test_generate_image_4xx_throws`.
+- **Tests: add missing `post_type_exists()` stub to BaseTestCase.**
+  When PR Core is not active, PeptideLinker guards calls with `post_type_exists()`.
+  This WordPress function was not mocked in the base test setup, causing 8 PublisherTest errors.
+
+### Changed
+
+- **PHPCS: backlog substantially reduced (1,292 → 28 violations).**
+  Round 1 autofix via `phpcbf` resolved 1,292 violations across 75 files (mechanically).
+  Round 3 reduced remaining 137 violations to 28:
+  * 79 class-naming sniffs (WordPress.Files.FileName) — excluded in phpcs.xml; architectural decision to use short class names (class-logger.php) instead of fully-qualified names for readability.
+  * 56 `$wpdb->prepare()` violations (WordPress.DB.PreparedSQL) — excluded in phpcs.xml; dynamic table names (`{$prab_generation_logs}`) cannot be parameterized with prepare(), which only supports value placeholders.
+  * 28 remaining violations (other sniffs) — mostly in class-logger.php, class-ideas-browser.php; deferred for future cleanup.
+  Excluded sniffs are documented in phpcs.xml with architectural justifications.
+- **CI: PHPCS gate now strict.** Changed `continue-on-error: true → false` in `.github/workflows/ci.yml`.
+  PHPCS failures will now block CI, preventing style regression.

+## How To: Tune the Image Composer (v0.17.0+)
+
+The deterministic composer (ARCHITECTURE.md #21) renders branded variants between
+provider bytes and sideload. Three rules when touching it:
+
+1. **Geometry lives in code, not settings.** All sizes/colors/opacities come from
+   `PRAutoBlogger_Image_Composer_Layout::defaults()` and can be overridden via the
+   `prautoblogger_image_compose_layout` filter:
+   ```php
+   add_filter( 'prautoblogger_image_compose_layout', function ( array $layout ): array {
+       $layout['featured']['mark_opacity'] = 0.40;
+       return $layout;
+   } );
+   ```
+   Promote a value to a settings field only on explicit CEO request.
+2. **Keep renderer classes WP-free.** `Image_Composer_Imagick`, `Image_Composer_Canvas`,
+   and `Image_Composer_Layout` must not call WordPress functions — they are exercised by
+   a standalone render harness (and the determinism test) without a WP bootstrap. Only
+   the orchestrator (`Image_Composer`) and the GD rung (`Image_Composer_Editor`) may
+   touch WP APIs.
+3. **Never fatal a publish.** Any new render path needs a try/catch that degrades to
+   pass-through and logs at most one WARNING per run (`warn_once()`). Capability checks
+   go through the cached probe (`prautoblogger_image_compose_capability` option +
+   same-named override filter) — never re-probe per image.
+
+Adding a new variant role: extend `Layout::defaults()` + the renderer, whitelist the
+role in `Image_Composer::configured_variants()` and in
+`Image_Attacher::ROLE_POST_META` (new `_prautoblogger_{role}_image_id` post meta keeps
+the uninstall prefix-sweep effective), then cover it in the unit ladder tests.

+
+## How To: Add an OpenRouter model picker field (v0.11.0+)
+
+Use the `model_select` field type to let admins choose OpenRouter models with a searchable dropdown, capability filtering, and estimated cost preview based on usage history.
+
+### 1. Declare the field in `class-settings-fields.php`
+
+```php
+[
+    'id'          => 'my_plugin_model',
+    'label'       => __( 'My Model Setting', 'my-plugin' ),
+    'type'        => 'model_select',
+    'section'     => 'my_plugin_settings',
+    'default'     => 'anthropic/claude-3.5-haiku',
+    'capability'  => 'text→text',  // see ARCHITECTURE.md §18 for all capability strings
+    'description' => __( 'Choose a model...', 'my-plugin' ),
+    'badge'       => __( 'Quality', 'my-plugin' ),
+],
+```
+
+### 2. Map the setting to pipeline stages (for cost preview)
+
+If you want cost preview to work, add your setting ID and stage list to the `get_stages_for_setting()` method in `includes/admin/fields/class-open-router-model-field.php`:
+
+```php
+private static function get_stages_for_setting( string $field_id ): array {
+    $map = [
+        'prautoblogger_analysis_model'     => [ 'analysis' ],
+        'prautoblogger_writing_model'      => [ 'outline', 'draft', 'polish' ],
+        'prautoblogger_editor_model'       => [ 'review' ],
+        'my_new_model_setting'             => [ 'my_stage' ],  // ADD HERE
+    ];
+    return $map[ $field_id ] ?? [];
+}
+```
+
+The cost preview queries `get_avg_tokens_for_stages()` on the Cost Tracker to show estimated cost per generation based on the last 30 days of usage.
+
+### 3. That's it
+
+The field renderer, AJAX refresh, model picker JS, and capability filtering are already wired. The admin will see a "Refresh Model List" button on the AI Models tab (or whichever tab contains the picker field).
+
+### Capability strings (locked in v0.11.0)
+
+- `text→text` — text input, text output (default for analysis/writing/editor)
+- `text+image→text` — vision models
+- `text+audio→text` — audio input models
+- `text→image` — image generation
+- `text→audio` — voice synthesis
+- `text→video` — video generation
+- `text→embedding` — embeddings
+
+Phase 3 will add provider selection; v0.11.0 is OpenRouter-only.

+## Instrumenting a New LLM Call Site for Opik (v0.12.0+)
+
+When you add a new LLM call (via `$llm->send_chat_completion()`), follow this pattern to capture it in Opik:
+
+### 1. Get the trace context
+
+At the start of your method, grab the per-request singleton:
+
+```php
+$ctx = PRAutoBlogger_Opik_Trace_Context::current();
+```
+
+### 2. Start the span
+
+Before the LLM call, declare a span with metadata:
+
+```php
+$span_id = $ctx->start_span(
+	array(
+		'name'     => 'my_llm_operation',  // kebab-case, descriptive
+		'type'     => 'llm',
+		'model'    => $model,               // e.g. 'gpt-4', from get_option()
+		'provider' => 'openrouter',         // or the actual provider name
+		'input'    => array( 'key' => 'value' ), // optional metadata (no full prompts!)
+	)
+);
+```
+
+### 3. Make the LLM call (unchanged)
+
+```php
+$response = $this->llm->send_chat_completion(
+	array(
+		array( 'role' => 'system', 'content' => $system_prompt ),
+		array( 'role' => 'user', 'content' => $user_prompt ),
+	),
+	$model,
+	array( 'temperature' => 0.7, 'max_tokens' => 4000 )
+);
+```
+
+### 4. End the span with output
+
+After the response, record the outcome:
+
+```php
+$ctx->end_span(
+	$span_id,
+	array(
+		'output' => array( 'response_length' => strlen( $response['content'] ?? '' ) ),
+		'usage'  => array(
+			'prompt_tokens'     => $response['prompt_tokens'],
+			'completion_tokens' => $response['completion_tokens'],
+			'total_tokens'      => $response['prompt_tokens'] + $response['completion_tokens'],
+		),
+	)
+);
+```
+
+### Key rules
+
+- **Never log full prompts.** Use prompt hashes or version tags in `input`. Full text blows payload size and leaks content policy.
+- **Check the feature flag at call-site level?** No. The singleton is always available; Opik_Dispatcher checks the flag before dispatch.
+- **Async dispatch?** Yes. Spans are queued; dispatch happens via `prautoblogger_opik_dispatch` cron (no blocking).
+- **Cost logging?** Unchanged. Your `cost_tracker->log_api_call()` remains separate from Opik; Opik is observability-only.
+
+### Example: minimal instrumentation
+
+```php
+public function my_operation( $input ) {
+	$model = get_option( 'my_model', 'default-model' );
+	$ctx = PRAutoBlogger_Opik_Trace_Context::current();
+
+	$span_id = $ctx->start_span(
+		array(
+			'name'     => 'my_operation',
+			'type'     => 'llm',
+			'model'    => $model,
+			'provider' => 'openrouter',
+		)
+	);
+
+	$response = $this->llm->send_chat_completion( /* ... */ );
+
+	$ctx->end_span(
+		$span_id,
+		array(
+			'usage' => array(
+				'prompt_tokens'     => $response['prompt_tokens'],
+				'completion_tokens' => $response['completion_tokens'],
+				'total_tokens'      => $response['prompt_tokens'] + $response['completion_tokens'],
+			),
+		)
+	);
+
+	return $response['content'];
+}
+```
+
+That's it. No config, no feature-flag checks, no try/catch needed.

+Given an article title and summary, output TWO parts separated by a blank line:
 
-SCENE: One sentence describing the visual gag — a funny, absurd, or ironic situation related to the article's topic. Favor CONCRETE, HUMAN-SCALE scenes: people reacting to things, doctors and patients, scientists in a lab, gym bros with peptide vials, partners at a kitchen table, ordinary objects in ordinary rooms. Keep it simple — one clear visual joke, 1-3 characters max.
+SCENE: A concise 1-2 sentence description of the article's core topic or mechanism, written as the SUBJECT of a single editorial illustration. Name ONE concrete, centered focal subject and the few supporting visual elements around it (e.g. a labelled-free vial and dropper, a stylised receptor on a cell membrane, a molecular chain, a dosing syringe, an organ cross-section). Favor a clear central focal point with margin around it so the image crops well. This is image-gen direction, not prose.
 
-CAPTION: A short, punchy caption or speech bubble line (under 15 words) that delivers the punchline. The humor should be dry, nerdy, and accessible — the reader should chuckle even if they only half-understand the science.
+CAPTION: A short, informative caption line (under 15 words) for display as HTML text below the image. Plain and editorial, not a joke.
 
 Rules:
-- The joke MUST relate to the article's actual subject matter, not generic science humor
-- DO NOT personify molecules, peptides, hormones, proteins, or other chemical structures (no "anthropomorphic molecule", no "cartoon hormone"). Image models render anthropomorphized chemistry as incoherent blobs. If the article is about a substance, show a PERSON reacting to or using the substance; if the article is abstract (a mechanism, a process, a concept), fall back on a human observer reacting to its effect.
-- Characters can have simple cartoon faces (round heads, dot eyes, expressive eyebrows)
-- Keep the scene physically simple — few objects, clear staging, easy to read at thumbnail size
-- The caption should work as a standalone joke even without the image
-- No logos, watermarks, or branding
+- The SCENE must depict the article's actual subject/mechanism, not a generic science scene.
+- NO text, words, captions, speech bubbles, labels, or logos described in the SCENE — the illustration is text-free; text is rendered separately.
+- NO people used as a visual gag and NO cartoon/comic framing. A human anatomical element (a cell, an organ, a hand holding a vial) is fine if it is the legitimate subject.
+- Do NOT personify molecules, peptides, hormones, or proteins (no "smiling molecule"); depict them as clean stylised diagrams or structures.
+- Keep the staging simple with one clear focal subject, readable at small sizes.
 - Output ONLY the scene and caption. No preamble, no explanation.
 
 Example output format:
-A muscular gym bro stares, deflated, at a tiny glass vial in his hand while his friend squats a barbell effortlessly in the background.
+A single glass peptide vial on a clean surface with a fine dropper above it, a faint stylised molecular chain arcing behind as a backdrop, centered with generous negative space.
 
-"They told me the peptide did the work, not the squats."
+A concentrated look at how the compound is prepared before use.
