β.4: one-lab provisioning (closes #4) by Rchari1 · Pull Request #10 · harmoniqs/amicode

Rchari1 · 2026-06-17T18:07:52Z

Closes #4. Stacked on #9 (β.3) → base retargets to main as the stack merges. Separate PR from β.6 (demo dry-run, coming next).

Makes a clean machine Amicode-ready + verifiable, per spec-20260617-134308-one-lab-provisioning.

What this is

Bundled pinned Julia project — packages/extension/julia/{Project,Manifest}.toml pins the vetted Piccolo 1.19 stack; provisioning is a deterministic Pkg.instantiate (no resolver drift, no sysimage).
scripts/install.sh — idempotent: checks Julia, instantiates ~/.amico/julia, code --install-extension, drops a starter lab.toml, prints next steps.
scripts/healthcheck.mjs — exit-coded; a pure resolveChecks() (unit-tested with injected probes) + probes for julia+Piccolo, opencode /event 200 (spawns β.2's boot-smoke), amico-run --help, and Bedrock-creds (config-level). All 4 ✓, exit 0 on this machine.
vsce packaging — pnpm --filter amicode-v2 package produces amicode.vsix (39 MB, 16 files); a packaging-manifest test asserts the VSIX actually contains the staged amico-run, vendored opencode, template, and the pinned julia project (guards the β.2 dropped-asset trap).
RUNBOOK.md — timed ≤60-min clean-machine steps.

AC → evidence

Issue AC	Evidence
Clean install ≤60min + amico-run finds bundled script (no exit-64)	install.sh + RUNBOOK; amico-run probe `--help` exits 0; β.3 ships the template
healthcheck exit 0 all-pass / non-zero precise message	`resolveChecks` unit tests (3) + live run: all 4 ✓ exit 0
VSIX contains amico-run + opencode + template + julia	packaging-manifest assertion (green): `extension/bin/dist/amico-run.js`, `vendor/opencode/darwin-arm64/opencode`, `templates/solve_template.jl`, `julia/Project.toml` all present

Scope guardrails held: no PackageCompiler sysimage and no multi-lab lab.toml schema (both Phase 2); deterministic instantiate from the committed Manifest.

Fast tier: 45 amico-run + 30 extension tests green from a clean install.

Gave β.4 a look — pulled it, CI green, scope is clean and in-lane. Two things stood out that are worth fixing before this is the install path we hand a lab.

Must change

package builds the extension + opencode but never builds/stages amico-run, so the VSIX can ship without the orchestrator — and the test that'd catch it is skipIf(no VSIX), so CI never does. Only the runtime healthcheck backstops it.
probeCreds regexes a .jsonc file, so a "model" inside a // comment passes the creds check (false green).

Taste / non-blocking

Pin the Julia minor to the 1.12.3 Manifest you vendor, so the healthcheck Julia and the shipped Manifest can't drift.
The probes (creds/julia/opencode/amicorun) have no tests — only the pure resolveChecks aggregator does.

+    "healthcheck": "node scripts/healthcheck.mjs",
+    "package": "pnpm run build && pnpm run fetch:opencode && vsce package --no-dependencies --allow-missing-repository -o amicode.vsix"


package never builds/stages amico-run — the VSIX can ship without it, and packaging.test.ts is skipIf(no VSIX) so CI won't catch it.

Fixed in 7c768d8 — the package script now runs pnpm --filter @amicode/amico-run build first, so the VSIX can't ship without the orchestrator. The packaging-manifest assertion verifies amico-run is present in the staged VSIX.

Regex on a .jsonc file — a "model" inside a // comment passes here. Parse with jsonc-parser (already a dep).

Fixed in 7c768d8 — probeCreds now strips JSONC (string-aware, so a // inside a URL/model-id is preserved) and JSON.parses the result, so a "model" mentioned inside a real comment can't false-pass. Covered in healthcheck.test.ts.

- package: build @amicode/amico-run before packaging, so esbuild's bin/ staging isn't silently skipped and the VSIX always ships the orchestrator (the packaging.test is skipIf-no-VSIX, so this was the real backstop). - healthcheck probeCreds: parse the opencode .jsonc (string-aware comment strip + JSON.parse) instead of regexing it — a "model" inside a // comment no longer false-passes, and the $schema URL's // is preserved.

Thanks Jack — both addressed in the latest push (rebased on the updated #9).

package stages amico-run: package now runs pnpm --filter @amicode/amico-run build first, so esbuild's bin/ staging isn't skipped and the VSIX always ships the orchestrator. (esbuild also already warns on a skipped stage as a backstop.)
creds probe / jsonc: probeCreds now strips JSONC comments (string-aware, so the $schema URL's // is preserved) and JSON.parses — a "model" inside a // comment no longer false-passes. Verified both cases. Note: I used a small string-aware strip rather than jsonc-parser — it isn't actually in the dep tree, and the strip avoids adding a dep across the whole stack; happy to switch to jsonc-parser if you'd prefer.

Taste: pinning the healthcheck Julia minor to the vendored 1.12.3 Manifest — sensible; I left it for a follow-up to keep this PR focused on the two must-changes. Noted.

Rchari1 · 2026-06-22T21:18:15Z

Thanks @jack-champagne — both must-changes are in 7c768d8:

package now builds/stages amico-run before packaging (VSIX can't ship without the orchestrator).
probeCreds parses with a string-aware JSONC strip + JSON.parse, so a "model" inside a // comment no longer false-passes.

The taste items (pin Julia minor to the vendored Manifest; probe-level tests) I'm treating as non-blocking follow-ups unless you'd rather they land here. Re-requesting review.

Provisioning machinery is solid — deterministic instantiate of the pinned stack, clean pure/impure split in healthcheck, VSIX-content guard. Notes:

[resolved in fix: chat actually runs solves — inject AGENTS.md via opencode instructions #12] Healthcheck validated ~/.amico/julia while the agent used amicode.juliaProject (default ""), and "" slipped past opencode_config.ts:46's ?? "UNSET" → a blank --project. Fixed in fix: chat actually runs solves — inject AGENTS.md via opencode instructions #12 via resolveJuliaProject → ~/.amico/julia; they agree once fix: chat actually runs solves — inject AGENTS.md via opencode instructions #12 lands.
[should-fix, in-PR] Julia version unpinned. Manifest pins julia_version = "1.12.3"; install.sh only checks command -v julia. A clean juliaup install of a different minor instantiates against a 1.12 Manifest and silently drifts — add a version gate.
[minor] install.sh exits 0 when code is absent (warn-and-continue) — "install succeeded" without the extension. And packaging.test.ts is skipIf(!VSIX), so the dropped-asset guard doesn't run in normal CI.

jack-champagne

Approving — provisioning is solid; the blank --project is fixed in #12. The julia-version gate is a worthwhile follow-up (comment above).
