npm Email Companion

npm controls the native "Successfully published" email template, so the email itself stays short. Treat this generated artifact as the full release-note companion for that email: it carries the Changeset summaries, CHANGELOG entry, publish workflow, npm tarball, and shasum when available.

Full Changeset Release Notes

Patch Changes

.changeset/bump-1.5.3.md

Version bump to 1.5.3 — publish the landing page congruence fixes, dashboard deep-linking, and README corrections that merged as #914 after 1.5.2 had already been published from #911.

.changeset/explainer-video-v2.md

Replace the landing-page explainer video with a reproducible 90-second animated
walkthrough that actually explains the mechanism — same-mistake-different-session
pain, 👎 → Pre-Action Gate extraction, gate fires on the next bad call,
compounding token savings, one-line install. Adds an offline render pipeline
(scripts/render-demo-video/) that drives a scripted 1920×1080 HTML animation
through headless Playwright and muxes an ElevenLabs/say narration track —
byte-reproducible on every re-render, no live agent session required. New
npm scripts: demo:narration, demo:render, demo:render:full.

.changeset/landing-page-congruence.md

Landing page congruence fixes and dashboard deep-linking:

• Remove misleading "1 agent" Free tier bullet (no per-agent enforcement exists in rate-limiter)
• Rephrase Free tier bullets to match actual code behavior (1 auto-promoted prevention rule, built-in safety gates)
• Add hash-based deep-linking to dashboard: /dashboard#insights, /dashboard#gates, /dashboard#export now auto-switch tabs
• "Visual gate debugger" link on Pro tier now deep-links to #insights (was pointing to root /dashboard)
• "DPO training data export" link on Pro tier now deep-links to #export
• Add public/dashboard.html, scripts/prompt-eval.js, bench/prompt-eval-suite.json, CHANGELOG.md to npm files whitelist — these were missing, breaking the dashboard for users running npx thumbgate pro
• New tests: 19 landing-page-claims (code-backed claim audit), 3 dashboard-deeplink-e2e (real server + HTTP fetch + hash validation)

.changeset/linkedin-comment-engage.md

Add LinkedIn one-shot comment engagement: publishComment publisher
(scripts/social-analytics/publishers/linkedin-comment.js) that posts a comment
on a specified activity URN via the socialActions endpoint, plus a
linkedin-comment-engage.yml workflow_dispatch that runs it with the
LINKEDIN_ACCESS_TOKEN / LINKEDIN_PERSON_URN secrets. Used for
high-signal targeted engagements on prospect / thought-leader posts
whose audience overlaps ThumbGate's ICP; bulk / scheduled engagement
still flows through Ralph Loop.

CHANGELOG.md Entry

No CHANGELOG.md section was found for 1.5.3; the release notes above were generated from the changed Changeset files.

Verification Standard

• Publish only runs from main after version sync, tests, and runtime proof pass.
• The npm package is smoke-tested after publish by installing thumbgate@VERSION in a clean runtime.
• GitHub Release notes are generated from Changesets, not only GitHub auto-generated PR titles.
