+## 2026-07-17T16:03:00Z — CRM plugin, gateway setup-wizard fix, CLI exit-code propagation (Claude Code)
+
+- **Agent/tool:** Claude Code
+- **Repos:** hermes-agent
+- **Done:**
+  - Restored bespoke telegram/slack/matrix setup dispatch in `hermes_cli/gateway.py`. Commit `e39b468` had deleted `_PLATFORMS` entries and `_builtin_setup_fn()` mappings for these adapters, falsely claiming they'd "moved to plugins/platforms/<name>/" (those plugin dirs never existed). This broke the platform-picker and specifically broke Matrix's documented "leave token empty for password login" path.
+  - Built `plugins/crm/` — a Dex-inspired personal CRM plugin (contacts, keep-in-touch cadences, interaction timeline, due-board, birthdays, cron-ready daily digest), modeled on the existing `plugins/teams_pipeline/` architecture. Hardened after a fan-out audit: `MAX_CADENCE_DAYS` overflow cap, month-aware calendar-date validation, fail-loud `CrmStoreError` on corrupt store files (previously silently returned empty data, risking clobber on next write), fixed a tag-leak bug in `render_digest`, corrected `docs/crm-pipeline.md`'s cron wiring example (shell substitution evaluated the digest once at cron-creation time instead of regenerating per fire).
+  - Fixed `hermes_cli/main.py`'s top-level dispatch: `args.func(args)`'s return value was discarded, so subcommands returning non-zero for real errors (1 = user error, 2 = usage error) still exited the process with 0, silently breaking scripted/cron callers checking `$?`. Verified safe via a subagent trace of all ~49 `set_defaults(func=...)` registrations.
+  - Bootstrapped this `docs/system-log/` directory per the account-wide documentation-duty convention (previously absent from this repo).
+- **Commits/PRs:** `1085b297` (#94), `4bb288b8` (#95), `b763b0fe` (#96) — all squash-merged to `main`.
+- **Follow-up:** none outstanding in this repo. Tracked retroactively in Linear project [Hermes-Agent: CRM Plugin & Platform Fixes](https://linear.app/dizhaky/project/hermes-agent-crm-plugin-and-platform-fixes-1d174ab077de) (DAN-2148, DAN-2149, DAN-2150 — all Done).

+# System log
+
+Append-only daily log of agent and automation activity in this repo.
+
+## File naming
+
+- One file per UTC day: `YYYY-MM-DD.md`
+- Create the file on first entry; never rewrite prior days
+
+## Entry format
+
+```markdown
+## YYYY-MM-DDTHH:MM:SSZ — Short title (agent/tool)
+
+- **Agent/tool:** Cursor | Claude Code | GitHub Actions | manual
+- **Repos:** repo-a, repo-b
+- **Done:** bullet summary of work completed
+- **Commits/PRs:** abc123, #42 (optional)
+- **Follow-up:** open items (optional)
+```
+
+## Rules
+
+1. **Append only** — do not edit or delete prior entries except to redact secrets
+2. **No secrets** — redact tokens, API keys, passwords, and credential file paths
+3. **UTC timestamps** — use ISO-8601 with `Z` suffix
+4. **One session, one entry** — merge related work from the same session into a single entry
+
+## When to log
+
+Log after any non-trivial session: feature work, bug fixes, CI changes, refactors, rollouts, or multi-file edits.
+
+Skip for typo-only or comment-only changes.
+
+## Canonical spec
+
+Account-wide standards live in [dizhaky/.github `docs/system-log/README.md`](https://github.com/dizhaky/.github/blob/main/docs/system-log/README.md) and Obsidian `Projects/Tech/Agent Documentation/STANDARDS`.
