fix: expand Runware pricing whitelist to all 15 registry models (v0.14.0)

All Runware model selections except schnell and dev were silently falling back to runware:100@1 (FLUX.1 schnell) because COST_PER_IMAGE only had 2 entries while the image model registry (v0.13.8) expanded to 15 models. resolve_model() falls back to schnell for any ID not in COST_PER_IMAGE, so SD3, FLUX.2, HiDream, TwinFlow, Z-Image, Qwen-Image, Krea, and GLM-Image all generated schnell images regardless of admin selection. Fix: add all 15 Runware model IDs to COST_PER_IMAGE and DEFAULT_STEPS with costs from runware.ai/pricing (April 2026). Add @see cross-ref to the registry to prevent future drift when new models are added.
fix: model picker price sort broken for image models (v0.13.9)

+## [0.14.0] - 2026-04-26
+
+### 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
+- New OpenRouter model: openai/gpt-5.4-image-2
+- Registry now includes last-verified date and update instructions in source comment

+
+## [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.

Author	SHA1	Message	Date
peptiderepo	236787ad09	fix: expand Runware pricing whitelist to all 15 registry models (v0.14.0) All Runware model selections except schnell and dev were silently falling back to runware:100@1 (FLUX.1 schnell) because COST_PER_IMAGE only had 2 entries while the image model registry (v0.13.8) expanded to 15 models. resolve_model() falls back to schnell for any ID not in COST_PER_IMAGE, so SD3, FLUX.2, HiDream, TwinFlow, Z-Image, Qwen-Image, Krea, and GLM-Image all generated schnell images regardless of admin selection. Fix: add all 15 Runware model IDs to COST_PER_IMAGE and DEFAULT_STEPS with costs from runware.ai/pricing (April 2026). Add @see cross-ref to the registry to prevent future drift when new models are added.	2026-04-26 04:05:39 +00:00
peptiderepo	ca82e395f4	fix: model picker price sort broken for image models (v0.13.9) applySort() always read input_price_per_m for price sorting, but image models carry cost_per_image instead — input_price_per_m is undefined on them, so every image model got an effective price of 0 and the sort was a no-op. Fix: detect image models via cost_per_image !== undefined and use that field when present; fall back to input_price_per_m for text models. Files changed: - assets/js/model-picker.js — applySort price branch - prautoblogger.php — version bump 0.13.8 → 0.13.9 - CHANGELOG.md — release notes	2026-04-26 02:36:56 +00:00
peptiderepo	3f60ecd0ff	feat: expand image model registry to 21 models (v0.13.8) Adds 13 new Runware text-to-image models and openai/gpt-5.4-image-2 via OpenRouter. All models live-verified 2026-04-26.	2026-04-26 03:49:25 +07:00
peptiderepo	046d57877c	fix: rebalance Posts list column widths (v0.13.7) 35% title + 255px fixed PRAB cols left ~50px per auto column. Replace with a balanced budget across all columns so Author, Categories, Tags, and Date all get enough room to render horizontally: title 22%, author 6%, categories 7%, tags 9%, date 8%, writing_model/image_model 85px each, cost 50px, peptide_topics 75px	2026-04-24 14:44:15 +00:00
peptiderepo	c628fc8cbb	fix: use width not min-width for Peptide Topics column (v0.13.6) table-layout: fixed ignores min-width — the WP posts list table uses fixed layout so min-width: 80px had no effect. Changed to width: 80px which is honoured under fixed-layout tables.	2026-04-24 14:13:05 +00:00
peptiderepo	6e9d2e3928	style: fix SQL string indentation (phpcbf)	2026-04-24 14:07:57 +00:00
peptiderepo	066e533f09	fix: cost column SQL error + Peptide Topics column squish (v0.13.5) Two bugs in class-post-list-columns.php: 1. Cost always showed $0.00: a PHP '// phpcs:ignore' comment was placed inside the SQL string literal, causing MariaDB syntax error on every render_cost_cell() query. Moved comment to the line above wpdb->prepare() where it belongs. 2. Peptide Topics column header compressed to near-zero width by the three fixed-width PRAB columns (Writing Model + Image Model + Cost = 255px). Added min-width: 80px to .column-taxonomy-peptide_topic so the header renders horizontally.	2026-04-24 14:06:23 +00:00
peptiderepo	7924b47913	fix: pin price column to right edge of row (v0.13.4) Root cause: .ab-mp-price and .ab-mp-ctx were siblings in .ab-mp-row-meta with price first. Description text is variable-length, so the meta div grew/shrank per row, shifting the price left/right. Fix: - Move price to last child in .ab-mp-row-meta so its right edge is always pinned to the row's fixed right edge - Add flex-shrink: 0 to .ab-mp-price so it never compresses - Cap .ab-mp-ctx at max-width 200px with text-overflow: ellipsis - Swap column header order (Context, then Price) to match new DOM order	2026-04-24 09:34:47 +00:00
peptiderepo	a5a370779a	fix: align price column header with data cells (v0.13.3) .ab-mp-col-price was missing min-width and right-alignment even though .ab-mp-price had both. The header sat left while values sat right, so they didn't track the same column edge. Added min-width: 90px and justify-content: flex-end to match.	2026-04-24 09:16:10 +00:00
peptiderepo	86f6801079	feat(model-picker): sortable column headers — Model, Price, Context - Add .ab-mp-col-headers bar between search and list with three clickable column headers: Model (sorts by name), Price in/out (sorts by input_price_per_m), Context (sorts by context_length) - Track sortState at module level so preference persists across open/close; clicking same column toggles asc/desc - Deprecated models always sink to bottom regardless of sort column - Add CSS for .ab-mp-col-headers, .ab-mp-col-header, .ab-mp-sort-arrow, .ab-mp-col-active; widths mirror existing row flex layout so columns visually align with data Bumps version 0.13.1 → 0.13.2	2026-04-24 09:05:54 +00:00
peptiderepo	89c2bafeec	fix: right-align price column in model picker modal (v0.13.1) Add min-width: 90px and text-align: right to .ab-mp-price so prices like $0.0006/image and $0.0800/image stack on a consistent right edge instead of floating at uneven offsets.	2026-04-24 09:00:36 +00:00

peptiderepo	c1d22fd275	fix: Opik autoloader gap — services/opik/ not scanned (v0.12.3) class-autoloader.php listed services/ but not services/opik/. All four Opik classes live in that subdirectory. Composer classmap covered it (tests passed); WP runtime autoloader would fatal in production on first Opik class reference. Adds services/opik/ to the scan list. Bumps to v0.12.3.	2026-04-24 11:08:23 +07:00
peptiderepo	b9dfc29436	fix: image style suffix empty-string bypass + image cost run_id mismatch (v0.12.2) Bug 1: extract get_style_suffix() helper that treats '' as "use default", applied to all 3 call sites in class-image-prompt-builder.php. Bug 2: thread $cost_tracker through ArticleWorker → Publisher → PostAssembler → ImagePipeline so image costs share the article's run_id in wp_prautoblogger_generation_log.
