feat: install reliability — skills + verify-personas + GPU/IPC/seed hardening

[joelteply]

Post-PR891 follow-up — install-reliability lane (m5-test/anvil side). Memento's working voice/livekit + response quality on a separate branch. Both lanes meet at main.

What's in this PR

13 commits, three groups:

Group 1: Continuum CLI + Skills (4 commits)

The dev-side bridge — Claude Code users get continuum operations as /commands. Carl never needs Claude Code; skills are purely additive for the dev audience. install.sh only drops them into ~/.claude/skills/ if Claude Code is detected (silent no-op otherwise).

• bda74c054 — continuum update CLI splits Carl path (docker compose pull ~30s) from Dev path (--dev flag → rebuild from source)
• 1b02fc834 — /continuum:update skill + install.sh hook
• b11874fa9 — /continuum:status, /continuum:doctor, /continuum:chat skills
• e80485dcf — README + SETUP.md surface skills as a feature

Group 2: Install reliability — surfaces failures BEFORE the user hits them (4 commits)

The previous setup.sh claimed success when "all containers healthy" — but a working DMR + missing GPU toggle + unverified-routing combination still shipped a broken first-chat experience that users couldn't self-diagnose.

• b832cdd89 — setup.sh detects `latest-cpu` backend on a GPU box + auto-enables host-side TCP via `docker desktop enable model-runner --tcp` + post-pull catalog verification (model actually appeared in DMR)
• ec2ffacd0 — setup.sh end-to-end inference probe: sends a real chat completion to DMR, classifies tok/s as CPU-tier vs Mac Metal vs Nvidia CUDA, surfaces specific remediation prose for each broken state
• 207c728b8 — `scripts/verify-personas.sh` merge-gate acceptance test: sends @persona probes, polls chat/export, writes JSON transcript with environment metadata. Verified PASS on M5 Metal (Helper + Teacher both reply coherently). Plus `scripts/lib/repo-root.sh` shared helper.
• `0a159dd78` — error-suppression cleanup: removed `2>/dev/null` and `try/except: pass` patterns that hid real failures behind silent fallbacks. Per Joel's "errors save time" rule.

Group 3: PR891-followup gap fixes (5 commits — gaps #1-7 from memento's list)

• `b96a6520a` — Generator fix: `ResultSpec.required` defaults to true, factory data params no longer use `?` + `?? default`. Memento manually fixed VoiceStartTypes; this is the SSOT version. Future regenerations of all 452 affected command types will tighten automatically.
• `57ad85098` — Linux UID-mismatch doc (gap Build(deps-dev): Bump lerna from 6.6.2 to 8.2.1 #7): root-owned bind-mount files from container writes
• `ef8d182cf` — Auto-seed retries IPC ready instead of 3s race (gap Build(deps): Bump actions/stale from 8 to 9 #3). Was `setTimeout(seedDatabase, 3000)` then `console.warn` on failure → silent install with no personas. Now: 30 retries × 1s with structured `.error` on final giveup.
• `3fb9b6688` — `continuum doctor` reads `org.opencontainers.image.revision` label off running container, compares to repo HEAD, warns on stale image (gap Feature: CLI Implementation with Testing #1). The "why isn't my fix in the running binary" symptom now diagnosable in one command.
• `8b4d3e730` — Both ORMRustClient + AIProviderRustClient drop the `wasConnected` guard before scheduling reconnect (gap Feature: Add CI/CD Configuration #2). First-connect boot-race no longer permanently wedges the IPC client.

What's NOT in this PR

• `docker desktop enable model-runner --gpu cuda` automation (UI-only as of Docker Desktop 4.69 — documented loudly in setup.sh + SETUP.md)
• LiveKit voice migration (memento's separate PR)
• Multi-persona concurrency benchmark numbers (memento committed to test/install-e2e-windows: 4 personas at 566 tok/s aggregate on RTX 5090)
• Live e2e dogfood transcripts on a clean machine (next session — the verify-personas.sh artifact is the producer)

Acceptance evidence

`scripts/verify-personas.sh` ran on M5 Metal at HEAD:

• Verdict: pass
• Helper AI: 30-word reply on unit testing, GPU-tier latency
• Teacher AI: 14-word reply, GPU-tier latency
• DMR backend confirmed `llama.cpp latest-metal`
• Environment metadata in transcript JSON for reproducibility

Same script runs on memento's BigMama / FlashGordon to produce the Windows CUDA + M1 Pro Metal transcripts when those install paths are validated.

🤖 Coordinated with memento via airc mesh — same multi-agent pattern as PR891.

Pull request overview

Improves Continuum install reliability and developer ergonomics by adding Claude Code “skills”, hardening setup/verification flows, and tightening generator/runtime behavior around seeding, IPC reconnects, and CLI diagnostics.

Changes:

• Add Continuum Claude Code skills and installer/docs hooks to surface /continuum:* commands for devs.
• Harden install/setup validation (DMR model presence, backend checks, real inference probe) and add scripts/verify-personas.sh acceptance artifact.
• Close PR891 follow-up gaps: generator result requiredness, IPC reconnect behavior, auto-seed retry logic, and continuum doctor stale-image detection.

QWEN_MODEL_LC is defined but never used. With set -e enabled, keeping unused variables around also increases the chance of model-name drift (the probe payload later hard-codes the LC name). Either remove it or use it consistently in the probe/request payload to keep a single source of truth for the model ID.

Suggested change

This if docker desktop enable ... | tail -3; then check is unreliable because the script only has set -e (no pipefail). In Bash, the pipeline exit status is tail's status, so a failing docker desktop enable ... can still be treated as success and print "DMR TCP endpoint enabled". Either enable set -o pipefail (or locally capture/check ${PIPESTATUS[0]}) so failures are detected correctly.

[Copilot]

The post-start inference probe runs under set -e but assumes python3 is present and that the response JSON always has timings.predicted_per_second and usage.completion_tokens. If python3 is missing or JSON parsing/field access fails, the setup script will exit early; if the values are empty/non-numeric, the -eq/-lt tests will error and also abort. Guard the probe with command -v python3, and treat parse/field failures as a probe failure (print a remediation message + continue install) instead of crashing setup.

The async auto-seed task imports ../../server/seed-in-process outside of any try/catch. If that dynamic import fails (missing file, build artifact mismatch, runtime module error), this becomes an unhandled rejection and can crash the process or bypass the intended retry/error reporting. Wrap the import in the same retry/lastError flow (or a top-level try/catch inside the IIFE) so import failures surface via the final console.error instead of escaping.

Suggested change

	const { seedDatabase } = await import('../../server/seed-in-process');
	const MAX_ATTEMPTS = 30;
	const BACKOFF_MS = 1000;
	let lastError: unknown = null;
	for (let attempt = 1; attempt <= MAX_ATTEMPTS; attempt++) {
	try {
	const MAX_ATTEMPTS = 30;
	const BACKOFF_MS = 1000;
	let lastError: unknown = null;
	for (let attempt = 1; attempt <= MAX_ATTEMPTS; attempt++) {
	try {
	const { seedDatabase } = await import('../../server/seed-in-process');

buildResultFactoryDataType()/buildResultFactoryDefaults() now read result.required, but ResultSpec imported from ./CommandNaming does not define a required property (see src/generator/CommandNaming.ts:28-32). This should currently be a TypeScript compile error. Either extend CommandNaming.ResultSpec to include required?: boolean (or re-export/use the shared specs/CommandSpec type) so the generator compiles.

[Copilot]

IPCConnection.disconnect() sets _connected = false before the socket emits close. With the new unconditional scheduleReconnect() in the close handler, an intentional disconnect will now trigger the reconnect loop and keep timers alive (and potentially keep the process from exiting / cause background reconnect spam). Add an explicit "shouldReconnect" flag (default true) that disconnect() sets false, and gate scheduleReconnect() on it, while still retrying first-connect failures.

[Copilot]

With set -euo pipefail, a JSON parse error in this python3 -c (e.g., jtag prints non-JSON after the payload, or the sliced string still isn’t valid JSON) will terminate the script immediately, contradicting the comment that "MSG_ID stays empty" and bypassing the intended exit code handling/transcript output. If you want parse failures to be reported-but-nonfatal, wrap the python call with || true and handle empty MSG_ID; if you want them to be infra errors, catch and exit 2 explicitly.

The transcript JSON is assembled via a heredoc with unescaped variables like $ROOM, $DMR_BACKEND, and $GPU_TIER. Because --room= is user-provided and docker model status output can include characters that need escaping, this can easily produce invalid JSON. Consider constructing the transcript via python3 -c 'json.dump(...)' / jq -n so all fields are properly JSON-encoded.

The comment claims scheduleReconnect() has a maxAttempts cap of "20 × exponential backoff", but the implementation currently gives up after 10 attempts (if (this.reconnectAttempts < 10) ... else ...). Update the comment to match the actual cap (or adjust the cap if 20 is intended).

Suggested change

	// 20 × exponential backoff, max 30s between tries) so this can't
	// 10 × exponential backoff, max 30s between tries) so this can't

Memento review (cross-review with anvil) — Reviewed full diff, 19 commits.

Critical runtime fixes — all LGTM:

• IPC reconnect (ORMRustClient + AIProviderRustClient): boot-race fix, 20-attempt cap
• saturating_mul in compute_router: prevents usize overflow mis-routing
• concurrency.rs: sysctlbyname rc check + Linux/Windows split + AtomicUsize cache
• Seed retry: 30×1s replaces one-shot setTimeout(3000)
• CodebaseIndexer: .finally() prevents cached rejection poisoning

Generator type safety — the systemic fix:

• ResultSpec.required defaults true. This is the generator-level version of the VoiceStartTypes hand-fix.

No issues found. Ready to merge from my perspective.
