Session Summary

Date: 2026-01-15

Focus Area: Complete ops-review fixes, research Slack bot options

Accomplishments

• Completed MED ops-review fixes from previous session
• Added backup-b2-failed notification service with OnFailure handlers
• Added network-online.target dependency to backup-b2-check
• Added TimeoutStartSec to backup services (2h backup, 1h check)
• Deployed backup module changes (generation 73)
• Verified system health post-upgrade: all 6 services active
• Analyzed LOW findings (statix W20) - skipped as style-only
• Closed y8le: accepted RocksDB backup consistency risk
• Updated previous session worklog with ops-review details
• Researched Spotify bot options (idonthavespotify, Odesli API)
• Located previous musiclink research in session history
• Investigated VS Code Claude extension auth persistence bug (w1mb)
• Identified root cause: home-manager read-only symlinks to Nix store
• Filed dotfiles-j06 for fix in dotfiles repo
• Added beads (bd) system-wide to ops-jrz1 (v0.47.2)

Key Decisions

Decision 1: Skip statix W20 warnings

• Context: Ops-review flagged repeated keys in Nix modules

• Options considered:

  1. Refactor to consolidate systemd.services blocks
  2. Skip - it's idiomatic NixOS module style
• Rationale: Current pattern (one service per block) is common in nixpkgs and more readable
• Impact: No changes; accepted as style preference

Decision 2: Accept RocksDB backup risk (y8le)

• Context: Matrix-continuwuity uses RocksDB, backed up while running

• Options considered:

  1. Stop service during backup (~30s downtime at 3 AM)
  2. Accept risk - RocksDB has crash consistency
• Rationale: Low traffic at 3 AM, multiple daily snapshots provide redundancy
• Impact: Closed y8le; will re-evaluate if restore drill shows corruption

Decision 3: Defer Slack bot work

• Context: Researched building Spotify link converter bot

• Options considered:

  1. Build new Go bot using Odesli API
  2. Wait for musiclink team's implementation
• Rationale: Another team already has musiclink project in progress
• Impact: No new bot work; wait to see how their implementation turns out

Technical Details

Odesli API Research

Found from previous session research:

• Endpoint: GET https://api.song.link/v1-alpha.1/links?url=<encoded-url>
• Auth: None required (API key optional for higher limits)
• Rate limits: 10 req/min (free) / 60 req/min (with key)
• Platforms: Spotify, YouTube Music, Apple Music, Tidal, Deezer, SoundCloud, etc.

Previous conclusion: Odesli is simpler than idonthavespotify (which still needs Spotify creds).

VS Code Claude Extension Auth Bug Investigation

Symptom: Claude Code VS Code extension loses auth on restart.

Root cause identified:

• home-manager symlinks \~/.config/Code/User/settings.json to read-only Nix store
• VS Code extensions cannot write to settings.json (EROFS error)
• No anthropic.claude-code directory created in globalStorage
• Extension fails silently when trying to persist auth state

Evidence:

• settings.json → /nix/store/.../settings.json (read-only symlink)
• Extension directory owned by root with dr-xr-xr-x permissions
• Credentials file \~/.claude/.credentials.json is writable (CLI works fine)

Workaround: Login via CLI (claude /login), extension reads shared credentials.

Fix: Filed dotfiles-j06 to address home-manager VS Code config options:

1. mutableExtensionsDir = true
2. Don't manage settings.json via home-manager
3. Use copy instead of symlink for settings

System Health Check

Post-upgrade verification:

• All 6 services active (postgresql, forgejo, matrix-continuwuity, mautrix-slack, maubot, nginx)
• No failed units
• Disk: 68% used (16G free)
• Memory: 506Mi / 1.9Gi (no swap)
• SSH noise from brute force attempts (normal internet background radiation)

Process and Workflow

What Worked Well

• Session history search found previous research quickly
• Incremental ops-review fix + deploy cycle was smooth

What Was Challenging

• Locating previous Spotify/Odesli research required jsonl grep

Context for Future Work

Open Questions

• How will musiclink team's bot turn out?
• Should we revisit Slack bot after seeing their implementation?

Next Steps

• Monitor musiclink team progress
• Continue with P2 research items or housekeeping when ready

Beads Activity

• Closed: y8le (RocksDB backup risk - accepted)
• Created: w1mb (VS Code auth persistence bug)
• Closed: w1mb (root cause identified, filed dotfiles-j06)
• Created: dotfiles-j06 (fix for home-manager VS Code symlinks)

Session Metrics

• Commits made: 4
• Deployments: generation 73, 74
• Research: Odesli API, musiclink history, VS Code auth persistence
• Bugs investigated: w1mb (VS Code auth) - root cause found
• Infrastructure: beads v0.47.2 added system-wide
