Learning curriculum

Sun 5/31 · LaunchAgent vs cron vs /schedule vs claude -p

Mon 6/1 · JARBUS events, the TTR card lifecycle, 'blocked' vs 'error'

Tue 6/2 · What's expensive, the 5-min cache TTL, when Opus vs Haiku

Wed 6/3 · 'use client', why ssr:false is forbidden in Server Components, CSS @import order

Thu 6/4 · When to reach for the research harness instead of hand-searching

Fri 6/5 · Self-paced autonomous work the harness can actually see fail

Sat 6/6 · Testing 3 versions of an idea cheaply, in isolation

Sun 6/7 · Why 'X doesn't exist' poisoned a session (#1776) and how to correct it

Mon 6/8 · Putting it together — steering the portfolio, not just the pipeline

Wed 6/10 · What Postgres + Supabase are, tables vs rows, the votes table you filled last week

Thu 6/11 · RLS policies, the rule that gated the Focaccia votes table, anon vs service keys

Fri 6/12 · Pages vs Workers, wrangler deploy, _redirects, custom domains (the 404 you fixed)

Mon 6/15 · Why Runway Model stalled 13 days unnoticed, STATUS drift, the shepherd daemon

Tue 6/16 · launchd, plists, why two of your jobs silently unloaded (the Jun 5 notification audit)

Wed 6/17 · How plan-day runs unattended, what --fallback-model does, the new June config that retries on overload

Thu 6/18 · Wall-clock watchdogs, gtimeout --kill-after, Automation Hygiene rule 2 (the May 30 plan-day overrun)

Wed 6/24 · classify.py: the tiering brain that decides quick-deliver vs run-protocol vs spawn-project, and should_hold_silently() — why thin/empty captures wait instead of firing a card.

Fri 6/26 · The 2026-06-10 lock: for_tom_html.render_review() is the ONE path; card types differ by content modules, never palette or layout. Why a per-workflow aesthetic is a regression.

Sun 6/28 · How observations (🎯 sessions, ✓ changes, ○ discoveries) are captured and searched across sessions — the layer this very weekly review reads from. An underused capability.

Mon 6/29 · The five load-bearing rules from CLAUDE.md (verify the side-effect not the trigger; proven watchdog; failures surface as a 🚨 Things task; upstream-aware fallback; LLM-runtime is the wrong layer for critical orchestration). This is the week you just lived: the 06-26 cascade left language/learning surfaces empty and needed a manual restore.

Tue 6/30 · Claude Code's --fallback-model (up to 3 models on overload/unavailable) and the wall-clock watchdog pattern. You ACCEPTED fallback chains on 06-09 but it was never wired into settings.json or the cron flags — this lesson closes that loop.

Mon 7/27 · OAuth session expiry on unattended `claude -p` runners: why the token refresh fails headlessly, what 'OAuth session expired and could not be refreshed' means, and the difference between interactive OAuth and API-key auth for cron jobs. This is the exact failure that killed plan-day Jul 22–26 while the dedup ledger correctly held it to one alert.

Tue 7/28 · Your dedup + auto-resolve layer (PDB commit d9b37fc): one 🚨 Things task per outage, incidents tracked open in data/alert-state.json with a repeat counter, auto-resolved on recovery. It absorbed 5 consecutive plan-day failures this week without spamming your inbox — the design working exactly as intended.

Wed 7/29 · Failure alerts only fire when a job runs and fails. Three weekly-reviews (Jul 5, 12, 19) exited 1 with zero surface signal — the cadence just vanished. The heartbeat/witness pattern: a separate checker asks 'did X leave its artifact in the last N hours?' instead of trusting X to report its own death. This is RESET-2026's 'unwitnessed system' diagnosis made concrete.

Thu 7/30 · The Jul 21 audit's roadmap: fail-loud defaults, declarative routing, a witness layer, and three-channel signal architecture (mapping LangChain human-in-the-loop patterns to your flows). With 16 days of sabbatical left, at most one gets built — this lesson is the triage.

Fri 7/31 · --fallback-model on headless runs: up to 3 models tried on overload/unavailable. Accepted 06-09, still unwired. New context: Opus 5 (1M context) is now Claude Code's default Opus, and Fable 5 was redeployed Jun 30 — your 'opus[1m]' alias inherits upgrades, but your cron wrappers still have no net when the primary is down.

Sat 8/1 · Two weeks out. The Jul 21 languages decommission (retire the LaunchAgent, retire the email, clean the output repo, one commit per layer) is your template for clean retirement. Keep/kill/mothball triage across the ~20 app.zorc.* LaunchAgents: anything you keep needs a witness; anything unwitnessed gets killed or mothballed.
