Claim-aware novelty rotation
3signals now rotates featured signals using evidence fingerprints, newly supported claims, unseen authors, and new entity mixes instead of relying only on broad topic freshness.
- The daily top three now targets at least two signals that are new or newly supported by fresh evidence.
- Manual test sends can avoid recording presentation history so they do not make the next real briefing look stale.
- Operator reports now explain novelty reasons, fingerprint diversity, and when the new-signal target is missed.

Secure 3signals.ai domain and cleaner browser trust
3signals now runs from the canonical 3signals.ai domain with HTTPS redirects, security headers, and a hardened browser delivery path.
- The site now redirects to the canonical HTTPS domain and sends HSTS plus browser security headers.
- The public pages were checked from a clean Chrome context for valid certificates, secure context behavior, and mixed-content regressions.
- The setup keeps old links working while steering readers to the trusted 3signals.ai experience.

Reset, rebuild, and test-send controls
The system now has secured reset and async job controls for wiping generated content, rebuilding from seed configuration, and sending targeted test newsletters.
- The reset flow clears retrieved content, vector data, generated wiki files, markdown vault artifacts, and newsletter cache while preserving seed configuration.
- Long-running jobs can be dispatched asynchronously and checked through secured status endpoints.
- Targeted recipient overrides make it possible to run production-like newsletter tests without mailing the full subscriber list.

Operator analytics, open tracking, and social surface
3signals now records newsletter opens, site access, feedback, and daily social publishing signals so each run can be evaluated as both a briefing and a product loop.
- The admin console summarizes users, email opens, site access, signups, feedback, and daily activity patterns.
- Newsletter footer actions collect per-issue thumbs-up/down feedback for future tuning.
- The site and emails consistently expose @3signalsai, Medium, LinkedIn, and share actions.

Freshness grading, reader feedback, and newsletter archive
3signals now grades the current pipeline for freshness, novelty, and impact before publication, stores each issue in a public archive, and adds per-recipient thumbs-up/down feedback links.
- The freshness gate favors signals backed by a newly retrieved premier article.
- Reader feedback is tied to the subscriber and issue so votes can tune future signal presentation.
- New subscribers receive the latest staged issue immediately after confirming their email.

Editorial QA for source-backed signal headlines
3signals now checks that every featured signal headline is supported by its premier article and supporting evidence before it appears in the newsletter, website, wiki highlights, or X thread.
- Mismatched premier articles can be replaced by better evidence from the same signal group.
- Over-strong wording is softened when the source material does not support it.
- Weak, promotional, or misleading evidence can hold a signal back from publication.
