+/**
+ * Run the eval CI job locally, in a container that matches the GitHub runner.
+ *
+ * The evals kept passing locally and failing in CI because a dev machine differs from
+ * a runner in ways the suite is sensitive to: a personal `~/.copilot` config, a
+ * different OS and CPU architecture, an already-populated `node_modules`, and a
+ * different Copilot token. This runs the real workflow steps — parsed out of
+ * `.github/workflows/agent-contracts.yml`, so they cannot drift from what CI does — on
+ * linux/amd64 with a clean HOME and a fresh `npm ci`.
+ *
+ * These are the credential-free gates. Running the agent itself now happens on MSBench
+ * (`.github/workflows/msbench-evals.yml`), which needs an Entra identity rather than a
+ * GitHub token and so cannot be reproduced by this script; use `evals/msbench/run.sh`.
+ *
+ * Usage:
+ * node evals/ci-local.ts # every cheap gate (seconds-to-minutes)
+ * node evals/ci-local.ts --merge # first merge the PR base, as CI does
+ * node evals/ci-local.ts --job contracts
+ *
+ * Runs straight off source via Node's built-in type stripping — no build step.

+# `evals/debug-probe` — does F5 actually work in the generated project?
+
+Copilot on Rails promises that after scaffolding you can press F5 and debug the
+project the agent just wrote. Every gate we have checks *artifacts*: that
+`launch.json` and `tasks.json` exist and are well-formed. That is necessary and
+weak — a `launch.json` can be perfectly valid and still not work.
+
+This directory holds the gate that checks the promise itself: **a breakpoint is
+hit in the generated project.** MSBench runs real VS Code with our real VSIX, so
+it is the only place such a gate can exist.
+
+```
+extension/ the probe: a test-only VS Code extension, installed alongside our VSIX
+certify.ts proves the gate passes on known-good code and goes red on mutations
+```
+
+The grader that reads the probe's verdict lives with the other graders, at
+[`evals/graders/validate-debug-breakpoint.ts`](../graders/validate-debug-breakpoint.ts).
+
+## ⚠️ This is the one thing under `evals/` with a build step
+
+Everything else here runs straight off `.ts` via Node 22's type stripping — no
+compile, no emitted JavaScript. **The probe cannot.** The VS Code extension host
+does not strip types, so `extension/` compiles to `out/` with `tsc` and ships as
+a `.vsix`. It is still TypeScript-only in source; there is simply no way to load
+a `.ts` file into the extension host.
+
+```bash
+cd extension && npm install && npm run compile # -> out/extension.js
+cd extension && npm run package # -> cor-debug-probe.vsix
+```
+
+`out/`, `node_modules/` and `*.vsix` are gitignored.
+
+## How it works
+
+The probe activates on startup, reads `debug-probe.json` from the workspace, and:
+
+1. checks the requested configuration exists in the project's own `launch.json`
+2. **resolves a breakpoint by pattern**, never by line number
+3. `addBreakpoints()` + `startDebugging()` against that configuration
+4. fires an HTTP trigger until something accepts a connection
+5. waits for the DAP `stopped` event, then reads the frame and its locals
+6. writes `.eval/debug-verdict.json`
+
+```json
+{
+ "launchConfig": "Golden App (debug)",
+ "breakpoint": { "glob": "src/**/*.js", "pattern": "status:\\s*'ok'" },
+ "trigger": { "url": "http://127.0.0.1:7071/api/health" },
+ "timeoutMs": 90000
+}
+```
+
+With no `debug-probe.json` present the probe does nothing, so it is safe to
+install unconditionally.
+
+## Four things here are counter-intuitive
+
+Each cost a debugging session to learn and each would have produced a *silently
+broken gate* rather than an obvious one. They are commented in place; this is the
+summary.
+
+**1. Function breakpoints do not work on Node, and fail silently.**
+The obvious design is `vscode.FunctionBreakpoint` — break on a function *name*,
+which is robust to generated code where line numbers are unknowable. It cannot
+work. js-debug ships `supportsFunctionBreakpoints: false` and does not implement
+`setFunctionBreakpoints` at all. Worse, VS Code's debug service guards the send
+on that capability, so the breakpoint is **discarded with no error surfaced to
+the extension**. A probe built this way would report "breakpoint never hit" on
+every run forever — a gate that can never pass, blaming the product. Hence glob +
+regex resolution, which is the only option.
+
+**2. `verified: false` does not mean the breakpoint is broken.**
+js-debug answers `verified: false, message: "Unbound breakpoint"` at set time
+because the script has not loaded yet, then rebinds later via a `breakpoint`
+event rather than a fresh `setBreakpoints` response. On the known-good fixture
+the breakpoint reports unverified and is hit a moment later. Gating on
+`verified === true` — the obvious check, and what the DAP field appears to be
+*for* — produces a gate that can never pass. It is recorded as a diagnostic and
+nothing more.
+
+**Do not gate on `verified`. Gate on the `stopped` event.** This is not a local
+quirk: it reproduced in all five MSBench container runs. From
+[`2026082623215161`](https://msbenchapp.azurewebsites.net/run-analysis/2026082623215161):
+
+```
+06:30:00.999 setBreakpoints response: [{"verified":false,"message":"Unbound breakpoint"}]
+06:30:01.074 startDebugging returned true
+06:30:01.581 trigger connected after 2 attempt(s)
+06:30:01.589 stopped: reason=breakpoint ← hit, 0.6s after being called unverified
+```
+
+The failure this avoids is the expensive kind: an intermittent **red against a
+working project**, which reads as a product regression and gets explained away
+as flaky agent output rather than investigated.
+
+**3. The trigger request never completes on a healthy run.**
+We break *mid-request*, so the HTTP response never arrives. The signal is
+**socket connected**, not response received. Awaiting the response times out
+against a working app and reports `appFailedToStart`.
+
+**4. Silence is a harness fault, not a product failure.**
+Workspace Trust blocks extension activation outright and its only symptom is an
+absent verdict file. The probe therefore writes `.eval/probe.log` the instant it
+activates, so "never activated" and "activated then stalled" can be told apart,
+and the grader treats a missing verdict as exit 3. Run VS Code with
+`--disable-workspace-trust`, or pre-trust the workspace.
+
+## The verdict discriminates six outcomes, not two
+
+Collapsing them is the failure mode this gate exists to avoid. `evals/src/gateHealth.ts`
+documents a gate that went 0-for-16 across every run ever executed because its
+probe signed requests with a corrupted key: no generated app could have passed,
+and ten percent of the corpus was billed to a harness defect.
+
+| Outcome | Meaning | Exit |
+| --- | --- | --- |
+| `hit` | execution reached the breakpoint | 0 |
+| `launchConfigInvalid` | no `launch.json`, or no configuration by that name | 1 |
+| `appFailedToStart` | the configuration ran but nothing came up | 1 |
+| `breakpointNotHit` | the app was reachable, execution never arrived | 1 |
+| `patternMatchedNothing` | the breakpoint could not be placed — **ambiguous** | 3 |
+| `probeError` | the probe itself broke | 3 |
+
+### Why `patternMatchedNothing` defaults to a harness fault
+
+A pattern that matches nothing means either the agent did not produce what we
+expected (product) or our pattern is wrong (harness). **From inside the probe
+those are identical.** When a signal is ambiguous we blame ourselves, because the
+errors are asymmetric: a harness fault miscounted as a product failure is
+invisible and quietly poisons the corpus, while a product failure miscounted as a
+harness fault is loud and gets investigated.
+
+So it can be tightened later with data rather than argued about, the verdict
+records `globMatchCount` and `filesMatchedByGlob` alongside the pattern. That
+distinguishes *"no file matched `src/**/*.js`"* from *"found `src/server.js` but
+no line matched `/health/`"* — very different diagnoses — without re-running
+anything.
+
+A stack whose contract genuinely guarantees the code exists can opt in per-stack:
+
+```bash
+node validate-debug-breakpoint.ts --pattern-miss-is-product-failure
+```
+
+## Certification
+
+A gate that cannot fail is not a gate, so both directions are proven.
+
+```bash
+node certify.ts --offline # 11 cases, no VS Code, ~2s — safe for CI
+node certify.ts --live # 9 cases, real VS Code + real js-debug
+node certify.ts # both
+```
+
+Useful flags: `--only=`, `--verbose`, `--vscode=/path/to/code`.
+
+**On Windows `code` is a `.cmd`**, which `spawnSync` cannot execute, so the live
+tier resolves `Code.exe` instead — from whatever `code.cmd` is on PATH, then the
+usual install locations. Before that it died with `spawnSync code ENOENT` before
+a single case ran and reported it as seven identical *"probe did NOT activate"*
+failures, which reads as a broken probe rather than a runner that never started
+one. The live tier had therefore never been run on Windows at all. Resolution
+happens only when the live tier is actually selected, so `--offline` still needs
+no VS Code.
+
+**Offline** synthesises verdict files and asserts the grader's exit code for
+each, including the ones that must never blame the product: a missing verdict, a
+malformed verdict, an unknown outcome, and a schema-version mismatch. This
+certifies the part that assigns blame, so it runs anywhere.
+
+**Live** stages the known-good fixture plus eight mutations and runs real VS Code
+against each. The load-bearing one is `mutation-breakpoint-unreachable`, which
+puts the breakpoint on the `POST` 400 branch while triggering `GET /api/health`:
+it must go red, and red for the right reason.
+
+The fixture is [`evals/grader-certification/reference-node-fullstack`](../grader-certification/reference-node-fullstack),
+reused as-is — it already ships `launch.json`, `tasks.json`, a health route and
+zero dependencies. This directory only reads it.
+
+## Wiring
+
+The probe rides into a run as a second `installExtensions` entry in
+[`msbench/config/base.yaml`](../msbench/config/base.yaml). That key
+**concatenates across config layers rather than replacing**, which is how our
+product VSIX already installs alongside `github.copilot-chat` — the probe is the
+second user of that behaviour.
+
+`run.sh` builds and stages `cor-debug-probe.vsix` next to the product VSIX, and
+checks the package actually contains `out/extension.js`: a VSIX packaged without
+compiling looks valid and then fails to activate, which from outside the
+container is indistinguishable from not being installed at all.
+
+The probe is **inert unless the workspace contains `debug-probe.json`**, so it is
+installed on every run and opted into per stimulus. It watches for that file
+rather than only reading it at activation, because whether the config's
+`script:` preamble seeds the workspace before or after the extension host
+finishes starting is not something we can verify from outside.
+
+### The one claim that needs a real run
+
+`evals/msbench/config/stimuli/debug-probe-smoke.yaml` is the smallest run that
+answers the only part of this design that could not be settled locally: **does a
+second extension install and activate alongside ours?** It uses a `probe-smoke`
+phase with no `chatMode` and no agent seeding, so the agent does essentially
+nothing — the evidence is written by the extension host before the first turn.
+It asserts the liveness sentinel, that `.eval/probe.log` exists, and nothing
+else. There is deliberately **no breakpoint assertion**: that is the next run,
+gated on this one, because asserting it here would conflate "the probe installed"
+with "the debugger works in a container" and a red result would not say which.
+
+### Container notes
+
+`pwa-node` needs no display (it drives CDP over a socket), but VS Code itself
+does — use `xvfb`, and `--no-sandbox` since the container runs as root. Keep the
+`--user-data-dir` path **short**: VS Code binds a Unix domain socket inside it
+and `sun_path` caps at ~104 bytes. Exceeding it makes VS Code start, open no
+window, write no logs, and hang until killed — indistinguishable from a broken
+extension. `certify.ts` asserts against this explicitly rather than
+rediscovering it. MSBench chooses that path, not us, so this is a hazard to
+recognise rather than one we can configure away.
+
+## Port squatters
+
+A process that is not the project under test, holding a port the probe depends
+on, is a **harness fault** — and one that would otherwise be reported as a
+product failure with no sign of anything wrong:
+
+- something on the **trigger port** serves the request instead of the app, so
+ the breakpoint is never reached ⇒ `breakpointNotHit`, exit 1
+- something on the **inspector port** stops node starting at all ⇒
+ `appFailedToStart`, exit 1
+
+Both are wrong, and both look completely ordinary. The probe therefore checks
+both ports *before* launching and returns `probeError` if either is taken —
+afterwards a squatter is indistinguishable from a broken project.
+
+The check **connects** rather than binds. A bind test against `127.0.0.1`
+reports a port free while a squatter holds `0.0.0.0` on macOS, which is exactly
+how a stranger's process gets mistaken for the application. `certify.ts` proves
+this with `mutation-port-squatted`, which holds `0.0.0.0:7071` from a separate
+process and requires exit 3.
+
+The inspector port matters more than it looks: `reference-node-fullstack` pins
+`--inspect=9229`, and a pinned inspector port collides across concurrent runs
+and survives a crashed earlier session. The probe cannot remap it — VS Code
+reads `launch.json` directly and is only handed a configuration *name* — so
+detecting and declining is the only honest option. Certification runs its cases
+strictly sequentially for the same reason. A stack template emitting a hardcoded
+inspector port should be fixed at the source rather than worked around here.
+
+### Why certification runs sequentially
+
+The live tier must not be parallelised. Its cases contend for two ports the
+fixture **hardcodes** — `7071` via `env.PORT` and `9229` via
+`runtimeArgs: ["--inspect=9229"]` — and the probe cannot remap either, because
+VS Code reads `launch.json` directly and is handed only a configuration *name*.
+Run two cases at once and the second finds a port held by the first. The port
+guard turns that into `probeError` rather than a silent wrong answer, so it
+fails loudly — but the suite would look broken instead of parallel. Making it
+faster means fixing the hardcoded ports in the fixture, not removing the
+sequencing. This is repeated as a comment on the loop in `certify.ts`, which is
+where someone optimising for speed will actually be looking.
+
+### One thing the probe does not do
+
+It never binds or allocates a port — it only *connects* to two whose numbers it
+is given. That matters because the allocation path is where this class of bug
+tends to survive a fix: a free-port search that binds `127.0.0.1` can be handed
+an ephemeral port a squatter already holds on `0.0.0.0`, and the caller then
+latches onto the squatter believing it chose a free port. There is no such path
+here by construction, and there should not be one added without the same
+connect-based check.
+
+## Measured in-container reliability
+
+`debug-breakpoint-node` was run five times against the known-good fixture, from
+an identical tree, to turn "it worked once" into a number.
+
+| Run | Outcome | Trigger attempts | launch→connect | connect→stop | Total |
+| --- | --- | --- | --- | --- | --- |
+| [`2026082623215161`](https://msbenchapp.azurewebsites.net/run-analysis/2026082623215161) | `hit` | 2 | 0.507s | 8ms | 7.28s |
+| [`2026082624051475`](https://msbenchapp.azurewebsites.net/run-analysis/2026082624051475) | `hit` | 2 | 0.512s | 6ms | 7.43s |
+| [`2026082624376225`](https://msbenchapp.azurewebsites.net/run-analysis/2026082624376225) | `hit` | 2 | 0.507s | 6ms | 6.76s |
+| [`2026082624660033`](https://msbenchapp.azurewebsites.net/run-analysis/2026082624660033) | `hit` | 2 | 0.516s | 6ms | 7.54s |
+| [`2026082626667577`](https://msbenchapp.azurewebsites.net/run-analysis/2026082626667577) | `hit` | 2 | 0.509s | 5ms | 7.34s |
+
+**5/5 `hit`.** js-debug launches a process, binds a breakpoint and stops on it
+under xvfb-as-root on Ubuntu 22.04 with Node v22.22.2, reproducibly.
+
+### The attempt count is a floor, not a ceiling
+
+It is tempting to read "2 attempts every time" as a thin margin — one slow
+container from needing 3, then 4, then failing. **That reading is wrong, and the
+distribution shows why.** `launch→connect` is 0.507–0.516s across all five runs,
+a 9ms spread, and `TRIGGER_RETRY_DELAY_MS` is 500ms. The app becomes ready
+somewhere under 500ms after `startDebugging` returns, so attempt 1 always fires
+too early and attempt 2 always succeeds. The 2 is a **property of the retry
+interval**, not evidence of a near-miss.
+
+Nothing caps the attempt count. The loop retries until the probe's deadline, so
+a slower container spends more attempts rather than failing. The margin that
+actually matters is **time-to-listen (~0.5s) against the probe budget (180s)** —
+roughly 350×. A container would have to be two orders of magnitude slower before
+this turned red, and if it were, the verdict would say `appFailedToStart` with
+the debuggee's own output attached.
+
+The number worth watching in future runs is therefore `launch→connect`, not the
+attempt count.
+
+### What this does and does not establish
+
+It establishes that **the container can host a debugger** — which is what the
+fixture is for. It says nothing about whether any particular generated project
+is debuggable; that is the gate's job once it runs behind real output, and it is
+only meaningful *because* this baseline exists. A red there can now be read as a
+product finding rather than an unexplained one.
+
+## Which stacks this gate can honestly answer for
+
+**It requires a stack whose debug adapter ships with VS Code** — in practice the
+Node family, via the built-in js-debug. That is a real constraint, not a
+preference, and wiring it unconditionally produces exactly the failure this gate
+was built to prevent.
+
+Four directions, all verified rather than reasoned about:
+
+**A `preLaunchTask` this environment cannot resolve is not a project that does not
+work.** An Azure Functions project declares `preLaunchTask: "func: host start"`
+with `"type": "func"`, and that provider comes from the Azure Functions
+extension — which the agent's own `.azure/vscode-debug-plan.md` lists as a
+prerequisite, and which is not installed here. With no provider the task never
+runs, nothing opens the inspector port, `startDebugging` returns false, and the
+verdict *was* `appFailedToStart`: **exit 1, blaming the product for a project it
+generated correctly.** Measured on
+[`grader-certification/stage-local-dev`](../grader-certification/stage-local-dev),
+where it took 64 seconds to say so. The probe now fetches the available tasks
+before launching and returns `probeError` (exit 3) naming the task and listing
+what does resolve — in about one second. Certified by
+`mutation-prelaunch-task-unresolvable`.
+
+**Attach configurations are driveable, and the check is deliberately about the
+task rather than about `request`.** The first version of this preflight declined
+every `request: attach` configuration, which would have written off the whole
+Functions stack on a false premise. It is false: VS Code runs the `isBackground`
+preLaunchTask, waits for its problem matcher to report ready, and attaches.
+Verified end to end against an attach configuration whose task starts
+`node --inspect=9229` from a `type: shell` task:
+
+```
+preLaunchTask "serve" resolves in this environment
+startDebugging returned true
+trigger connected after 1 attempt(s)
+stopped: reason=breakpoint session=Remote Process [0] « Attach Under Background Task
+outcome: hit
+```
+
+Certified by `mutation-attach-with-resolvable-task-is-driven`, which exists so
+that mistake cannot be made again silently.
+
+**So the Functions stack is answerable here.** It needs two things, and the
+custom image (`msbench-1.1.0`) already carries one:
+
+| Needed | Provides | Status |
+| --- | --- | --- |
+| `ms-azuretools.vscode-azurefunctions` | the `func` **task type**, so `preLaunchTask` resolves | added to [`msbench/config/base.yaml`](../msbench/config/base.yaml) |
+| `func` on PATH | the Functions host itself | already in the custom image |
+
+Measured on `stage-local-dev` with the extension installed into an isolated
+extensions dir — the preflight goes from declining to passing:
+
+```
+preLaunchTask "func: host start" resolves in this environment
+trigger port 127.0.0.1:7071 is free
+```
+
+**A breakpoint hit in a Functions project is not yet proven**, and the remaining
+distance is honest to state: the task chain is
+`func: host start` → `api: build` → `install`, so the project must install and
+compile inside the probe budget, and this fixture's breakpoint sits on
+`status = 'healthy'`, which only executes when PostgreSQL *and* Azurite answer.
+Locally neither runs, so the branch is unreachable; the custom image starts both
+in the phase preamble. That makes the remaining proof a container run rather than
+a local experiment.
+
+**The extension's dependency is on the extension under test, and the install
+order protects it.** `vscode-azurefunctions` depends on
+`vscode-azureresourcegroups` — us — and installing it pulls that from the
+marketplace. The wrong order would silently replace the VSIX being evaluated with
+a shipped release, and every run would grade the wrong build. Verified rather
+than assumed: with the dependency already installed, VS Code leaves it alone
+(installing `0.12.0` first, then the Functions extension, leaves `0.12.0` on
+disk). Our VSIX is the first `installExtensions` entry, so it is always in place
+first.
+
+**A launch configuration naming an adapter we do not install used to produce a
+fabricated red.** `debugpy`, `go` and `coreclr` are not in this container. With
+one of those, `startDebugging` never resolves, the probe hits its deadline and
+the verdict was `appFailedToStart` — **exit 1, blaming the product for a project
+it built correctly**, since that configuration would work on a developer machine
+with the extension installed. Reproduced by setting `type: "debugpy"` on the
+known-good fixture; the verdict even misattributed the cause to "an unfinishable
+preLaunchTask". The probe now checks `contributes.debuggers[].type` across
+installed extensions before launching and returns `probeError` (exit 3) naming
+the missing adapter and listing the ones available. Certified by
+`mutation-debug-adapter-missing`.
+
+**With no `debug-probe.json`, the gate reports exit 3 forever.** The probe idles,
+no verdict is written, and the grader correctly calls that a harness fault. But
+MSBench collapses exit 1 and exit 3 into "non-zero", so on any stimulus that does
+not opt in, a `requires: {}` wiring shows a permanently failing assertion. That
+is the "gate that cannot pass" shape displaced into the exit-3 column.
+
+So the gate should be wired where the stimulus writes a probe spec **and** the
+stack is one the harness can drive. Everywhere else it is an environment gap: it
+has a real question and no way to ask it, which is a `knownGap`, not a red.

+# Integration Plan
+
+## Overview
+
+Integrate the browser client and Node.js API through same-origin HTTP routes. The browser calls the live backend and never imports preview or mock data modules.
+
+## Backend
+
+| Field | Value |
+|-------|-------|
+| Project folder | `.` (repository root) |
+| Build command | `npm run build` |
+| Run command | `npm start` |
+| Port | 7071 (override with `PORT`) |
+| Health endpoint | `GET /api/health` |
+
+The Node.js service in `src/server.js` exposes health, list, and create routes. It validates project names and returns explicit HTTP statuses.
+
+## API Routes
+
+| # | Method | Path | Description |
+|---|--------|------|-------------|
+| 1 | GET | `/api/health` | Report readiness |
+| 2 | GET | `/api/items` | List projects |
+| 3 | POST | `/api/items` | Create a project |
+
+## Services
+
+| Service | Classification | Role |
+|---------|---------------|------|
+| File repository (IItemRepository) | Essential | Persist project records |
+| Static file server | Essential | Serve HTML, JS, and CSS from `public/` |
+
+## Validation
+
+Run build, generated tests, lint, browser actions, accessibility checks, persistence restart, and debugger readiness.
