chore(v0.8.0): version bump + CHANGELOG + ARCHITECTURE.md for image bundle

Bump plugin header and PRAUTOBLOGGER_VERSION 0.7.3 → 0.8.0. Minor bump
because Commit D removes the Image Provider dropdown from admin (a
UX-visible change), not a patch.

CHANGELOG:
- Changed: collapsed Image Provider + Model dropdowns; provider derived.
- Added: Image Prompt Instructions setting; Retry NSFW-Blocked Images
  setting.
- Fixed: silent per-image failures in the event log.

ARCHITECTURE.md:
- Stage 6b (Image Pipeline) callout now describes provider derivation
  and the NSFW-retry fallback path.
- wp_options table lists the four new/changed keys
  (`prautoblogger_image_provider` as derived, new
  `prautoblogger_image_prompt_instructions`,
  `prautoblogger_image_nsfw_retry`, and the one-shot migration flag
  `prautoblogger_migrated_image_provider_v080`).

DB schema unchanged — no PRAUTOBLOGGER_DB_VERSION bump needed.

Final commit of the v0.8.0 image bundle (thread image-mime-bug).

-When a pipeline dies between post creation and the final `Post_Assembler::amortize_research_costs()` call (Hostinger exec kill, OOM, LiteSpeed cut, fatal), the shared `llm_research` cost row stays in `prab_generation_log` with `post_id = NULL` and sibling articles understate their true cost in the breakdown popover. A new daily WP-Cron event `prautoblogger_reap_orphan_research_rows` (hooked to `PRAutoBlogger_Research_Reaper::on_cron`, 03:15 server time — 15 min after the primary generation cron) scans for orphan rows older than a 1-hour grace window, looks up sibling posts by `_prautoblogger_run_id` post_meta (fallback: distinct `post_id`s in gen_log for the same run_id), and delegates to the existing idempotent `amortize_research_costs()` on match. Orphans that still have no siblings after 7 days are deleted outright as sunk cost. A one-time activator migration (`prautoblogger_migrated_run_id_meta_v081`) back-populates `_prautoblogger_run_id` on existing posts from gen_log so the meta-primary path works on upgrade. Manual ops trigger: `wp prautoblogger reap-research`.

 Reddit rejected our OAuth API application (April 2026). We initially switched to PullPush.io, but its index was frequently stale or unavailable. Reddit's RSS/Atom feeds (`/r/{sub}/hot.rss`) proved the most reliable option — they work from datacenter IPs where .json gets 403, require no auth, and have no apparent rate limit. The .json endpoints are kept as a fallback for posts and as the sole source for comment data. Each collected item's metadata includes a `data_source` field (`reddit_rss` or `reddit_json`) for auditability.

The registry class (`class-open-router-model-registry.php`) takes all config via constructor (option name, transient name, endpoint URL) — no PRAUTOBLOGGER_* constants inside the class body.

-### #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).
-
-### #16: Image generation via Cloudflare Workers AI (FLUX.1) — SUPERSEDED v0.10.0
-Kept here for history. Until v0.8.2 the default image backend was FLUX.1 schnell on Cloudflare Workers AI, routed via the Cloudflare AI Gateway for caching + unified telemetry. In v0.9.0 (2026-04-21) Runware FLUX.1 schnell became the default (65× cheaper, see ADR #17). In v0.10.0 (2026-04-21) the Cloudflare Workers AI provider was removed entirely — classes, settings, tests, and registry entries are gone; any CF user is migrated to `runware:100@1` on upgrade via `PRAutoBlogger_Migrate_Remove_Cloudflare_V0100::run()`. The Cloudflare AI Gateway in front of OpenRouter (ADR #15) is unaffected — it is a distinct integration.
-
+### #16: Image generation via Cloudflare Workers AI (FLUX.1), direct (not via AI Gateway)
+The image-generation layer (started 2026-04-15, tracked in `convo/prautoblogger/threads/2026-04-image-pipeline/`) uses FLUX.1 [schnell] on Cloudflare Workers AI as its default model, chosen for its ~$0.0011/MP cost and 2–3 sec latency. FLUX.1 [dev] is a ~4× cost upgrade exposed as a dropdown for specific posts that warrant it. Calls go directly to `https://api.cloudflare.com/client/v4/accounts/{id}/ai/run/@cf/black-forest-labs/...`, *not* through the Cloudflare AI Gateway that we use for OpenRouter — the gateway route to Workers AI currently 403s (pre-existing open issue). The provider lives behind `PRAutoBlogger_Image_Provider_Interface`, so the decision is trivially reversible: switching to a different image API (DALL-E, Replicate, a future AI Gateway route) is a new class implementation plus a one-line swap in the pipeline wiring. Trade-off: we run two different Cloudflare integration paths (gateway for OpenRouter LLMs, direct for Workers AI images) until the gateway route stabilizes — minor cognitive overhead, zero functional downside.
 
 ### #15: Optional Cloudflare AI Gateway in front of OpenRouter
 We already use Cloudflare for DNS/CDN on peptiderepo.com, so layering AI Gateway in front of OpenRouter is zero marginal infrastructure. It gives us response caching (meaningful for repeated classification/scoring calls), a unified cost/latency dashboard, rate limiting, and provider fallback — all of which we would otherwise have to build ourselves to satisfy the CTO cost-tracking rules. Kept as an opt-in URL setting (`prautoblogger_ai_gateway_base_url`) so the plugin still works unchanged out of the box and can be bypassed instantly if the gateway misbehaves. The gateway is a transparent OpenRouter-compatible proxy; no new provider class is needed, and the response parsing path (`usage`, `choices[0].message.content`) is unchanged.

-### #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.

 ## 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.

-## [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.
-
-## [0.10.0] — 2026-04-21
-
-### Removed
-
-- **Cloudflare Workers AI as image provider.** The four `class-cloudflare-image-*`
-  provider files are gone along with their unit tests and the three
-  CF-specific options (`prautoblogger_cloudflare_ai_token`,
-  `prautoblogger_cloudflare_account_id`, `prautoblogger_cf_image_via_gateway`).
-  Runware FLUX.1 schnell produces equivalent-quality output at ~65×
-  less cost and eliminates a duplicated settings surface. The
-  `flux-1-schnell` registry entry that mapped to the CF provider is
-  removed; the legacy slug now resolves to an empty provider (caught
-  by the migration).
-
-### Changed
-
-- **Sites on any `cloudflare` image provider auto-migrate to
-  `runware:100@1` on upgrade.** New migration
-  `PRAutoBlogger_Migrate_Remove_Cloudflare_V0100::run()` runs from
-  `admin_init` once per site. Detects three legacy shapes: registry-
-  derived provider `cloudflare`, `prautoblogger_image_provider` option
-  set to `cloudflare`, or the legacy slug `flux-1-schnell`. Sets
-  `prautoblogger_image_provider` + `prautoblogger_image_model` to the
-  Runware schnell pair and deletes the three dead CF options. Idempotent
-  via `prautoblogger_migrated_remove_cloudflare_v0100` flag — running
-  twice is a no-op and will not clobber a post-migration manual choice.
-- **Image provider dispatch fallback is now Runware, not Cloudflare.**
-  `PRAutoBlogger_Image_Pipeline::create_default_provider()` returns
-  `PRAutoBlogger_Runware_Image_Provider` for any unrecognised
-  `prautoblogger_image_provider` value. An unmigrated install still
-  gets a working pipeline instead of a fatal.
-
-### Note
-
-- **Cloudflare AI Gateway fronting OpenRouter is unaffected.** The
-  `prautoblogger_ai_gateway_base_url` + `prautoblogger_ai_gateway_cache_ttl`
-  options, their settings fields, `class-open-router-config.php`
-  gateway resolution, and `class-open-router-request-builder.php`
-  `cf-aig-cache-ttl` headers are all intentionally untouched. The AI
-  Gateway is a proxy/cache layer in front of OpenRouter and is
-  orthogonal to the CF Workers AI image provider removal. The
-  migration test asserts this invariant explicitly.
-
-### Cost impact
-
-Zero recurring spend from CF Workers AI image generation (the
-peptiderepo.com install was still on CF as recently as v0.8.2 — see
-commit `80a7e11`). No new prompt tokens, no change in model mix for
-sites already on Runware or OpenRouter.
-
-### Migration checklist (for anyone else running this plugin)
-
-1. On first admin_init after upgrade, the migration will flip
-   `prautoblogger_image_provider` to `runware` and
-   `prautoblogger_image_model` to `runware:100@1` if you were on CF.
-2. **Set `prautoblogger_runware_api_key`** in Settings → Images if you
-   hadn't already — image generation will fail until it is set.
-3. The CF API token + account ID options are deleted by the migration;
-   you don't need to do anything.
-4. If you want to switch back to OpenRouter (Gemini) instead of
-   Runware, just change the Image Model picker after the migration
-   has run.

-## [0.9.0] — 2026-04-21
-
-### Added
-
-- **Runware (FLUX.1 schnell) as the default image provider.** New
-  provider at `includes/providers/class-runware-image-*` generates
-  ~$0.0006/image on FLUX.1 schnell (`runware:100@1`) — roughly 65× cheaper
-  than the previous default (Gemini 2.5 Flash Image via OpenRouter at
-  ~$0.039/image). FLUX.1 dev (`runware:101@1`, ~$0.02/image) is also
-  available for higher-fidelity runs. The provider mirrors the
-  OpenRouter split: interface + provider + support + pricing + batch,
-  all under the 300-line cap.
-- **True parallel image generation.** `PRAutoBlogger_Runware_Image_Batch`
-  uses `curl_multi_init/exec/select` to fire all imageInference POSTs
-  concurrently, then downloads the signed URLs concurrently. Wall-clock
-  for the A/B pair drops to ≈ the slowest single image instead of the
-  sum of both.
-- **v0.9.0 one-time migration.** Sites where the image model is empty
-  or still pinned to `google/gemini-2.5-flash-image` are auto-flipped
-  to `runware:100@1` on upgrade, with the provider re-derived from the
-  registry. Flag: `prautoblogger_migrated_default_image_v090`. The
-  Runware API key option (`prautoblogger_runware_api_key`) was added
-  to the `enc:`-prefix migration list so Settings writes go through
-  the same encryption-at-rest path as the other provider keys.
-
-### Changed
-
-- **Image prompt builder steered away from abstract/chemical subjects.**
-  The rewriter system prompt now explicitly refuses to personify
-  molecules, peptides, hormones, or proteins — FLUX (and most diffusion
-  image models) render "anthropomorphic peptide" as an incoherent blob.
-  Default scene guidance is now "concrete, human-scale scenes: people
-  reacting to things, doctors and patients, gym bros with vials, etc."
-  Style suffix unchanged — single-panel comic aesthetic preserved. See
-  `includes/core/class-image-prompt-builder.php::REWRITER_SYSTEM_PROMPT`.
-- **Default image model flipped to `runware:100@1` (FLUX.1 schnell).**
-  `PRAUTOBLOGGER_DEFAULT_IMAGE_PROVIDER` and
-  `PRAUTOBLOGGER_DEFAULT_IMAGE_MODEL` constants in `prautoblogger.php`
-  updated. Cloudflare flux-1-schnell remains in the registry as a legacy
-  fallback for any operators who set it explicitly. Rationale:
-  `image-style` memory (2026-04-21) — schnell passed the comic A/B
-  round and the cost delta funds more generations for the same monthly
-  budget.
-
-### Cost impact
-
-At 50 articles/day × 2 image A/B = 100 images/day:
-
-- Before (Gemini 2.5 Flash Image via OpenRouter): ≈ $3.90/day, ≈ $117/mo
-- After (FLUX.1 schnell via Runware):             ≈ $0.06/day, ≈ $1.80/mo
-
-Net saving: ~$115/mo at current traffic, funded by a single provider
-swap with no user-visible change in article quality.
-
-## [0.8.2] — 2026-04-21
-
-### Fixed
-
-- **Daily generation schedule now honors site timezone.** Previously
-  the time configured in Settings → Schedule was interpreted as UTC
-  (WordPress core forces `date_default_timezone_set('UTC')`), causing
-  runs to fire N hours off from user intent where N is the site's UTC
-  offset. On peptiderepo.com (Asia/Singapore, UTC+8), a `schedule_time`
-  of `06:00` fired at 14:00 local. An on-upgrade one-shot migration
-  (`prautoblogger_migrated_schedule_tz_v082`) reschedules the existing
-  daily cron in the site's configured timezone — no user action
-  required.
-
-### Changed
-
-- **Cloudflare Workers AI image calls now route through the AI Gateway
-  by default.** The 2026-04-15 regression that caused the gateway route
-  to 403 on Workers AI has been resolved upstream. Routing via the
-  gateway gives us response caching, unified cost/latency dashboard,
-  and rate limiting for free, mirroring the OpenRouter LLM path. A new
-  admin toggle `prautoblogger_cf_image_via_gateway` (default on) lets
-  operators force direct-API if the gateway route regresses again,
-  without clearing the gateway URL setting the LLM provider depends on.
-- **"Generation Time" settings description** now names the site's
-  configured timezone explicitly (from `wp_timezone_string()`) instead
-  of the ambiguous "server timezone" label — operators can see at a
-  glance which zone their input is being interpreted in.
-
-## [0.8.1] — 2026-04-21
-
-### Fixed
-
-- **Orphaned LLM research costs now reaped daily.** When a pipeline died
-  between post creation and the final cost-amortization step (e.g.
-  execution-time kill on shared hosting), the `llm_research` row stayed
-  unlinked and the affected articles' cost popovers understated true spend.
-  A new daily cron (`prautoblogger_reap_orphan_research_rows`, 03:15
-  server time) retroactively amortizes orphan rows against posts from
-  the same run. Includes a one-time activator migration to back-populate
-  `_prautoblogger_run_id` post_meta for existing posts.
-- **GA4 Property ID admin description corrected.** The field description
-  previously instructed users to enter `properties/XXXXXXXXX`, but the
-  GA4 client already prepends the `properties/` URL segment internally —
-  a double-prefixed value would 404. Description now asks for the digits
-  only, matching actual code behavior.
-
-### Added
-
-- New WP-CLI command `wp prautoblogger reap-research` for manual reaping
-  and ops debugging.
-- `Publisher::build_meta()` now writes `_prautoblogger_run_id` on every
-  generated post, so the reaper has a direct meta path from run_id to
-  sibling posts without walking `wp_prautoblogger_generation_log`.

- *
- * When a pipeline run dies between post creation and the final
- * `Post_Assembler::amortize_research_costs()` call (Hostinger exec kill,
- * OOM, LiteSpeed cut, fatal), the shared research-cost row stays in
- * `wp_prautoblogger_generation_log` with `post_id = NULL` and the
- * articles from that run understate their true cost in the popover.
- *
- * This reaper scans for such orphan rows once a day, finds their sibling
- * posts via the `_prautoblogger_run_id` post_meta (primary) or the
- * gen_log's own post-linked rows (fallback for legacy posts that
- * predate the meta), and delegates to the existing idempotent
- * `amortize_research_costs()` method. Orphans that still have no
- * siblings after 7 days are deleted outright as sunk cost.
- *
- * Spec-wise the CTO asked for the reap method to live on Post_Assembler;
- * hosting it here instead keeps Post_Assembler under the 300-line cap
- * (it grew past 300 with the reap method attached) and colocates the
- * attribution logic next to the cron/CLI plumbing that triggers it.
- *
- * Triggered by:
- * - WP-Cron: `prautoblogger_reap_orphan_research_rows` (daily, 03:15).
- * - WP-CLI:  `wp prautoblogger reap-research` (manual ops trigger).
- * Dependencies: PRAutoBlogger_Post_Assembler (amortize_research_costs),
- *               PRAutoBlogger_Logger, WordPress $wpdb + get_posts.
