Cerebrum

OpenWolf's learning memory. Updated automatically as the AI learns from interactions. Do not edit manually unless correcting an error. Last updated: 2026-10-06

User Preferences

• Writes in Portuguese (pt-BR); answer in Portuguese. Wants things finished end to end: merged, released, deployed and checked in production, without being asked again (said so on 2026-10-22).
• Likes a clean interface with every function reachable (Apple / Anthropic as references, Outlook over Gmail), dark theme by default with a light one.

Key Learnings

• Project: LambdaMail
• Description: A self-hosted mail server with an integrated webmail and admin console, built to

Do-Not-Repeat

• [2026-10-22] git add -A swept the untracked .wolf/ and CLAUDE.md into a public repo. Add explicit paths (git add services migrations), never -A.
• [2026-10-22] Deploy is two steps: PATCH the Coolify env IMAGE_TAG to sha-<commit> and only then POST /deploy. A deploy without the PATCH redeploys the old image and still says "finished". Wait for the Release run to be completed, not just for gh run watch to return.
• [2026-10-22] pkill -f <pattern> kills the shell that is running it when the pattern appears in the command text. Use a bracket such as [m]ock.mjs, and never in a command that also contains the pattern as plain text.
• [2026-10-22] ~/.claude/tools/chrome-claude --print-path launches Chrome. Pass the wrapper only as executablePath.
• [2026-10-22] services/protocols e2e tests apply only migration 0001. Delivery code must not call SQL functions or columns from later migrations.
• [2026-10-22] A <Button> inside a <form> submits it unless type="button" (Undo send used to resend the message).
• [2026-10-22] Never run side effects inside a React state updater (it can run twice).
• [2026-10-23] Inside a JS template literal \\d silently becomes d. For scripts embedded in template strings write [0-9] instead of \\d, and test the script's behaviour, not only that it is present.

Decision Log

• 2026-10-22 Sessions: webmail session is 30 days and renewed daily while in use; each account is also a lm_acct_<id> cookie, lm_user_session stays the active one so the Go service and the middleware needed no change. Console stays at 8 hours.
• 2026-10-22 Trusted senders live in table trusted_senders; delivery rescues a Junk verdict only when DMARC passed, or SPF passed for the From domain (a forged From must not be rescued).
• 2026-10-22 Conversations: thread_id is written at delivery (Message-ID, then In-Reply-To/References, then Re:-subject); NULL means "its own conversation" via COALESCE(thread_id, id). Subject key is computed in Go at delivery and in SQL (lm_subject_key) for the backfill; a test holds them equal.
• 2026-10-22 Themes: every colour is a CSS variable per theme (globals.css), Tailwind scales (slate, indigo, amber, rose, emerald) read them, ink is the on-ground colour. Dark is default; the theme is chosen by a script in <head> before first paint. Font Geist is self-hosted (@fontsource-variable/geist).
• 2026-10-23 Logo: a lambda of two straight strokes of one weight, ends cut square, joined without a seam, flat ultramarine tile with continuous corners. The first version (round caps, gradient, envelope flap) read as childish; do not go back to round-capped strokes. Generator: scripts/brand/ (mark.py, icons.mjs); Logo.tsx carries the same path.
• 2026-10-23 Reader: a message written plainly is drawn in the app's colours (transparent frame, text lifted if too dark, white backdrops cleared); a designed one (backgrounds, bgcolor, 3+ tables) keeps a white sheet. Decided by looksDesigned in lib/emailBody.ts; a reply's quoted history folds behind a button.
