feat(seo): aviso de colisión de tema en /generate blog en

Al publicar el draft EN en Ghost, el título propuesto se compara contra
los posts published+scheduled del sitio (corpus vía Admin API — incluye
la cola programada, justo el caso del doble Kecksburg del 2026-07-10) con
el topic_collision vendorizado. Si colisiona, el notice de Telegram lleva
un bloque "🚨 Posible colisión de tema" en las tres rutas (live, dryrun,
bare). Nunca bloquea: el draft se crea igual, el humano decide (fusionar,
retitular o enlazar a propósito). Solo lang=en (stopwords inglesas).
Títulos ajenos saneados de entidades Markdown (regla de _safe_send).
Aislamiento: cualquier fallo del check → notice sin bloque y warning en
logs, jamás rompe la publicación.

+# ResearchOwl — Known Issues & Operational Gotchas
+
+## Brotli / aiohttp incompatibility
+
+Do NOT install any brotli backend (`Brotli`, `brotlicffi`) while on aiohttp 3.14.x.
+aiohttp's incremental brotli decompressor is broken and fails intermittently
+depending on stream chunking ("Can not decode content-encoding: br" on VALID
+streams — the same bytes decompress fine offline; httpx is unaffected).
+
+Extra trap: merely *installing* a backend makes aiohttp advertise `br` in the
+default `Accept-Encoding` of every session that doesn't set one explicitly.
+On 2026-07-04 a scraper fix installed brotlicffi and inadvertently enabled br
+project-wide: Ghost/Cloudflare responded in brotli, the decode blew up AFTER
+Ghost had already accepted the POST, and the publish fallback re-published →
+duplicate drafts + silently lost SEO notices.
+
+Fix applied (commits `397546a` + `76c927f` + `7d07375`, guard relocated
+2026-07-05):
+- no brotli backend in requirements.txt (comment there explains why),
+- explicit `Accept-Encoding: gzip, deflate` on all Ghost/autofill aiohttp
+  sessions and on the scraper HEADERS (`57f341f`),
+- duplicate guard INSIDE `GhostPublisher.publish_draft` (covers every caller,
+  including `/publish`): if the POST is accepted (2xx) but reading the response
+  fails, it recovers the just-created draft via `find_draft_by_title(title,
+  since=attempt_start)` instead of raising. The guard only fires after an
+  accepted POST — a pre-POST failure (Ollama down, menu fetch, links) never
+  triggers it, so a stale same-title draft from a previous run can no longer
+  swallow freshly generated content.
+
+Note: with no backend installed there is NO brotli fallback at all — a server
+that responds `Content-Encoding: br` without it being advertised (misbehaving
+CDN) fails undecodable and that source is lost. Accepted trade-off.
+
+The header value lives in one place: `SAFE_ACCEPT_ENCODING` in `src/config.py`.
+Every aiohttp session/request must use it explicitly — never rely on aiohttp's
+default Accept-Encoding, which silently grows `br` if a backend appears.
+
+Re-test with disclosure.org before ever re-enabling br (e.g. after an aiohttp
+upgrade).
+
+## SQLite WAL mode + read-only mounts
+
+The database runs in WAL mode, so even read-only access needs the `-shm` file
+writable, or must open with `sqlite3 "file:...?immutable=1"`. Backups (daily
+CronJob `researchowl-db-backup`, 03:00 Europe/Madrid, PVC `researchowl-backups`,
+7-day retention) inherit WAL mode: to inspect one from a read-only mount use
+`?immutable=1`; to restore, copy it to a writable location first.
+
+## DDG (duckduckgo_search) blocks the event loop
+
+`DDGS()` is synchronous (blocking requests inside). Never call it directly from
+async code — always wrap in `loop.run_in_executor()` (see `_ddg_text_sync` /
+`_ddg_videos_sync` in `src/scraper/exhaustive.py`). Direct calls froze the
+entire Telegram bot during searches until fixed on 2026-07-04 (`8dfd011`).
+
+## Google News RSS is a dead end from this infrastructure
+
+`news.google.com/rss` entry links point to `/rss/articles/CBMi…` redirects that
+hit a consent wall from EU IPs, and the inner `AU_yqL` id is only resolvable via
+Google's private batchexecute API. Do not retry. The news seed uses Bing News
+RSS instead (`ENABLE_NEWS_SEED`, real publisher URL in the `?url=` param of
+apiclick.aspx — unwrapped by `_unwrap_news_link`).
+
+## Large sources can OOM-kill the pod
+
+On 2026-07-10 the pod was OOMKilled (memory limit was 1Gi) mid-research: a
+batch of 20 concurrent sources hit a 98k-word document plus several large PDFs
+at once, and pdfplumber's parse spiked RAM past the limit. The in-memory
+research task died with the pod and its session sat in `running` forever.
+
+Mitigations now in place:
+
+- Memory limit raised to 2Gi (`k8s-manifests/researchowl/deployment.yaml`).
+- PDFs capped at 15MB (was 50MB), checked both via Content-Length and actual
+  body size; pdfplumber runs in `run_in_executor` (it is sync + CPU-heavy and
+  also froze the event loop, same class of bug as DDGS) and flushes its page
+  cache per page.
+- Extracted content is truncated to `max_content_length` (300k chars) before
+  hitting `source_contents`.
+- On startup the bot marks orphaned `running` sessions as `interrupted`.
+
+If a research still dies, the scraped sources survive in the DB: `/process`
+re-chunks and scores them without re-scraping.
