Wrap `model_research` (String), `classify_schema` (Value), and
`classification_categories` (Vec<String>) in Arc before the batch
loops so spawned tasks clone a cheap pointer instead of the full
heap data on every iteration. Also removes the redundant intermediate
`mdl`/`class_sys`/`class_user` bindings in both classify loops.

- Replace iterating DashMap check with atomic DashSet insert in create_job to
eliminate the race condition where double-click could create two concurrent
jobs for the same user
- Add release_user method called at end of generation task (normal, timeout,
and panic paths) so the generating slot is always freed
- Wrap run_generation in tokio::time::timeout(900s) to prevent hung LLM calls
from blocking the generation slot forever
- Spawn a second task to await the JoinHandle and call release_user + send
error event if the generation task panics, preventing SSE clients from
hanging indefinitely
- Update cleanup_expired to also remove users from generating_users set
- Update tests to call release_user after completion/error to match new contract

Adds an optional article_url column to llm_call_log so classify_summarize
entries are traceable back to their source article in the LLM Logs UI.

Add a user-configurable batch_size setting (default 5, range 1-20)
that controls how many articles are processed in parallel during
Phase 1 scrape+classify. Previously hardcoded to 5.

- Remove 10-source cap; all sources are now processed
- Increase max links per source from 10 to 15
- Extract article links in parallel (up to 5 concurrent) using JoinSet
- Shuffle candidate URLs after history filtering to interleave sources
- Add DELETE /api/v1/article-history endpoint to clear all history for a user

- Add get_last_source_url() to article_history db module for source rotation
- Remove head_html field from ScrapedContent struct and scrape_url function
- Fix synthesis.rs scrape_single_article_with_llm to pass empty string instead of removed field

Replace the three-method LlmProvider trait (generate_search_pass,
generate_rewrite_pass, supports_web_search) and ProviderCapabilities
with a single call_llm method. Update all three provider implementations
(Gemini, OpenAI, Anthropic) and all callers in synthesis.rs,
source_scraper.rs, and api_keys.rs.

Add source_url field to ScrapedNewsItem and a trace_article helper that
inserts into article_history with full provenance metadata. Instrument
Phase 1 (empty content, history dedup, source diversity) and Phase 2
(homepage filter, cross-phase dedup, history dedup, empty content) so
every dropped article is recorded with its filter reason. Replace the
old insert_urls call with per-article trace_article calls for used
articles, preserving dedup semantics via url_hash.

Accumulates overflow articles from both classification phases and redistributes
them into the Autre category when total articles fall below 75% of the configured
max, respecting per-source diversity limits.

Returns a (result, overflow) tuple so callers can access articles that
could not fit in any category or Autre. Also adds the
SYNTHESIS_MIN_FILL_RATIO constant for the upcoming fill-up logic.

The rewrite pass shared the search pass schema which enforced minItems/maxItems
equal to max_items_per_category. After filter_empty_scraped_articles removed
old/failed articles, the scraped data had fewer items than the schema required,
causing the LLM to duplicate content to fill the quota.
Now build_rewrite_schema counts actual items per category from the scraped data
and sets minItems/maxItems accordingly. Also removed dead domain_counts variable.

- filter_empty_scraped_articles: removes articles with empty scraped content
(too old, soft 404, scrape failure) before the rewrite pass, preventing
empty articles in the final synthesis
- restore_scraped_urls: already existed, now has unit tests
- E2E test: added assertions for no Wikipedia URLs, no empty summaries,
and updated settings payload with new fields (max_articles_per_source,
source_diversity_window)
- 4 new unit tests for filter_empty + restore_scraped_urls

The rewrite pass can replace validated URLs with hallucinated ones (Wikipedia,
corporate sites) despite being instructed to preserve them. After the rewrite,
restore_scraped_urls() replaces each article's URL with the original scraped
URL by matching on position (category + item index). Logs when a URL is
restored so hallucination patterns can be monitored.

- Add max_articles_per_source setting (default 3, range 1-10) with migration,
backend model, DB queries, and frontend number input
- Add limit_articles_per_source filter: spreads articles across categories
(1 per domain per category first), then fills remaining slots up to the limit
- Add dedup_by_url filter: removes duplicate URLs across categories (case-insensitive)
- Pipeline order: parse → filter_homepage → dedup_by_url → limit_per_source → scrape
- 10 new unit tests covering spread, cap enforcement, dedup, and edge cases

The adaptive pipeline skipped the scrape+rewrite pass when the LLM's search
results had URLs starting with "http". But LLMs hallucinate plausible URLs
(Wikipedia, corporate sites) that pass the http check but aren't actual source
articles. The scrape pass catches these by fetching each URL and validating
the content exists. Always running the full pipeline ensures URL integrity.

The LLM was returning only 1 article per category despite the user setting 4.
- Added minItems/maxItems to the category array schema (enforced by OpenAI strict mode)
- Changed prompt from "au maximum N actualites" to "exactement N actualites"
- Schema builder now takes max_items_per_category parameter

LLM output occasionally contains \u0000 null bytes (e.g., "annonc\u0000...")
which PostgreSQL rejects in JSONB columns. Added sanitize_json_null_bytes()
that recursively strips null bytes from all string values before DB insert.

The scraper client (build_scraper_client) has a 15s timeout appropriate for web
scraping, but LLM API calls — especially with web search — take 30-60s. LLM
providers now build their own reqwest client with 120s timeout via build_llm_client().

Bugs fixed:
- resolve_model queried non-existent admin_provider_models table (use JSONB query on admin_providers)
- key_prefix VARCHAR(10) too short for 11-char prefix (migration to VARCHAR(12))
- API key test schema missing additionalProperties: false (OpenAI strict mode)
- CSP missing font-src data: directive (PDF font embedding blocked)
- Magic link URL not logged in test mode (can't verify without real email)
- Rust 1.85 Docker image too old for dependencies (bumped to 1.88)
Tests added to prevent recurrence:
- schema_meets_openai_strict_mode_requirements: validates additionalProperties on all objects
- key_prefix_full_length_stored_in_db: verifies 11-char prefix survives DB round-trip
- generate_pipeline_resolves_model_from_admin_config: exercises full generation pipeline

- Extract auth::create_and_send_magic_link() to deduplicate token rollback logic
- Replace (i32, i32, RateLimiter) tuple with named UserRateLimitEntry struct
- Use DashMap entry API for atomic rate limiter lookup (fixes TOCTOU race)
- Pre-allocate scraper body Vec from Content-Length when available
