Focus

• Emacs keybindings and spell check configuration

Log

Session 16:49 (presentations)

• Learned Doom Emacs markdown editing basics: C-z toggles Evil mode to Emacs state, navigation keys (C-p/n/b/f, M-b/f, C-a/e), markdown-mode commands (C-c C-l for links, C-c C-t for headings, TAB/S-TAB for folding)
• Set up Spanish spell check in Doom Emacs:
  • Enabled (spell +flyspell) module in init.el
  • Downloaded es_ES.dic and es_ES.aff from LibreOffice dictionaries to ~/.local/share/hunspell/
  • Configured DICPATH environment variable and ispell-dictionary in config.el
  • Dictionary switching via M-x ispell-change-dictionary
• Next: None — session was ad-hoc Q&A, no pending items

Tasks created

Decisions

• Installed Spanish dictionary via direct download (no rpm-ostree/reboot needed)

Session 19:40 (general)

• Investigated ESP32-C3 USB connection issue from 2026-06-06 log
• Searched Universal Blue Discourse + ublue-os GitHub — no prior ESP32-related issues found
• Found esp-idf #9657 (Ubuntu), similar symptom: ESP32-C3 USB detected but missing JTAG; resolved via udev/forum workaround
• Checked kernel: cdc_acm driver is loaded, matches CDC-ACM interfaces by class/subclass/protocol
• Kernel has esp32s3-acm DT binding but that's device-side (gadget), not host-side
• No kernel patches exist for ESP32-C3 USB on linux-usb mailing list
• User connected ESP32-C3 — cdc_acm DOES bind and creates /dev/ttyACM0, but device brownout-cycles every ~3s (same as ESP8266 in the earlier session)
• Changed USB ports — same cycling; ruled out specific port issue
• Discussed power: 3.7V 18650 won't work (too low for USB 5V regulator, too high for 3.3V pin at full charge); needs external 5V (power bank, phone charger)
• User needs dialout group membership for device access
• Arc: Confirmed there is no missing kernel driver — cdc_acm handles the ESP32-C3 USB Serial/JTAG controller natively via standard CDC-ACM interface matching (VID 0x303a, PID 0x1001). The actual problem is brownout, same as the ESP8266.
• Next: Test ESP32-C3 with external 5V power (power bank or phone charger) to confirm brownout stops; add user to dialout group for permissions

Session (elegua)

• TDD red-phase sprint: wrote 8 failing test files covering the upcoming implementation phase
• Established pattern: pytest.importorskip for API tests (SKIP), xfail(strict=True) for CLI subprocess tests (XFAIL) — needed to pass pre-push hook
• Tests written and closed (with ro5u-universal review for each):
  • tests/cli/test_full_pipeline.py — elegua run --full-pipeline concordance table output (elegua-kaqt)
  • tests/comparison/test_shrinking.py — DisagreementMinimizer / MinimizedDisagreement (elegua-o3id)
  • tests/cli/test_filters.py — --tag, --capability, --adapter, --changed, --last-run-failures flags (elegua-wp8s)
  • tests/test_matrix.py — expand_matrix, resolve_inheritance with cycle detection (elegua-skhz)
  • tests/test_dispatch.py — dispatch_parallel, AdapterPool, bounded pool exhaustion (elegua-exgo)
  • tests/comparison/test_convergence.py — ConvergenceFixture with 4 reference modes (elegua-2r8)
  • tests/test_relation_plugins.py — EqualityPlugin, LinearCombinationPlugin, NumericalDerivativePlugin, ConvergenceResidualPlugin (elegua-779)
  • tests/test_differential_loader.py — load_differential_fixture, evaluation order, adapter defaults, validation errors (elegua-bon)
• Key fixes caught by ro5u and ruff: set-vs-list order assertion, unused imports (F401), regex non-raw strings (RUF043), em dash in TOML, × Unicode in comments, CLI TOML schema mismatch (adapter not a valid meta field)
• Verified TestFileMeta schema (bridge.py) and Adapter ABC interface (adapter.py) before writing tests
• Next: Implementation tickets now unblocked: elegua-t5ih, elegua-ouqt, elegua-dfm5, elegua-38bh, elegua-vyt, elegua-pvr
