ci(compat-matrix): make CF engine readiness diagnostics actionable on timeout

[bpamiri]

Summary

When the compat-matrix Wait for CF engine to be ready step times out (5 minutes), it currently dumps docker logs ... | tail -50. On BoxLang+Wheels that output is dominated by ~30 lines of undertow/runwar request-pipeline stack frames, with the actual exception buried earlier in the log. A maintainer staring at the CI log can't tell whether:

• the engine never bound a port (container broken), or
• the engine is bound but returning 5xx to every request (app broken — e.g. #2646's $blockInProduction not found symptom on BoxLang).

This PR makes that distinction obvious without changing the success-path behavior.

What changed

The probe now tracks the last observed HTTP status code across attempts. Every 10 attempts it logs partial state (container=running, http=500) so progress is visible mid-loop. On timeout:

• Classifies as "no response received" (HTTP 000) or "engine bound but returning errors" (5xx).
• For the 5xx case, prints the first 500 bytes of the response body — surfacing the actual exception class instead of just stack frames.
• Dumps both a stack-frame-stripped 100-line slice (anything matching ^\s*at\s or runwar.context - at is filtered out) and the raw tail -200. Signal-to-noise is much better, but raw logs are still available for deeper digging.

Also moves ${{ matrix.cfengine }} interpolation into an env: block and references it as $CFENGINE in the shell — the standard workflow-hardening pattern from GitHub's workflow-injection guide. Matrix values are hardcoded ([lucee6, lucee7, adobe2023, adobe2025, boxlang]) so this is not a security fix — just keeps the script consistent with the recommended pattern as it grows.

Background

While investigating #2649 (BoxLang test failure rate) I discovered the BoxLang job in compat-matrix has been failing at CF engine not ready after 60 attempts on the last three scheduled runs (2026-05-03, 2026-05-10, 2026-05-12). The root cause was the $blockInProduction bug (#2646) — every GET / was returning 500, so the probe's HTTP-status check (200|404|302) timed out forever. That underlying defect is already fixed by #2648 (merged into develop earlier today), and a local docker run of the post-#2648 BoxLang image now returns 200 OK on GET /. But the CI never re-ran on develop after that merge, and even if it had succeeded, the previous failures were unnecessarily hard to debug. This PR closes that diagnostic gap so the next regression of this shape is one CI log read instead of a half-hour archaeology dig.

Verification

Local simulation against three scenarios (a Python http.server returning HTTP 200, HTTP 500 with a fake BoxRuntimeException body, and no server at all):

--- Scenario 3: no server (port 58997) ---
TIMEOUT (last code: 000 -> engine never bound to 58997)

--- Scenario 1: HTTP 200 (port 58998) ---
READY (HTTP 200 on attempt 1)

--- Scenario 2: HTTP 500 (port 58999) ---
TIMEOUT (last code: 500 -> engine bound but returning errors)
  body sample: BoxRuntimeException: Function blockInProduction not found

Also validated:

• actionlint/shellcheck clean on the modified run: block (existing SC2086 hits elsewhere in the file are pre-existing and out of scope).
• A naive port of the original probe-with-|| echo "000" produced last code: 000000 on the no-server scenario; the local test caught that and the fix went in before commit (the comment above the curl call explains the trap).

What this PR is NOT

• Not a fix for Core test suite has high failure/error rate on BoxLang (35 failures, 125 errors, 3526 passing) #2649 itself. That issue is an aggregate report (~160 failures) classified as other by the bot's triage. Decomposition into individual per-failure issues is still required — see the fix-held comment.
• Not the BoxLang readiness fix. That landed in fix(dispatch): preserve receiver context in BoxLang invokeMethod (#2646) #2648. This PR just makes the next failure of this class diagnose-able from CI logs.

Related: #2646, #2648, #2649

Test plan

• actionlint + shellcheck pass on the edited block (verified via rhysd/actionlint:latest Docker image)
• Local probe simulation: 200 → READY, 500 → TIMEOUT with body sample, no-server → TIMEOUT with "engine never bound"
• Diff reviewed: no changes to success-path output beyond appending (HTTP $LAST_HTTP_CODE on attempt $N) to the ready message
• Triggered compat-matrix on develop or this branch — not done locally; requires shared-infrastructure permission. Recommend a manual workflow_dispatch run on this branch before marking ready, OR merge as-is and observe via the next scheduled Sunday run

Wheels Framework

CFML MVC framework with ActiveRecord ORM. Models in app/models/, controllers in app/controllers/, views in app/views/, migrations in app/migrator/migrations/, config in config/, tests in tests/.

Prefer MCP tools when the Wheels MCP server is available (mcp__wheels__*). Fall back to CLI otherwise.

Task	MCP	CLI
Generate	wheels_generate(type, name, attributes)	wheels g model/controller/scaffold Name attrs
Migrate	wheels_migrate(action="latest|up|down|info")	wheels migrate latest|up|down|info

Admin	—	wheels g admin ModelName
Seed	—	wheels seed (legacy alias: wheels db:seed)

Critical Anti-Patterns (Top 10)

These are the most common mistakes when generating Wheels code. Check every time.

1. Mixed Argument Styles

Wheels functions cannot mix positional and named arguments. This is the #1 error source.

// WRONG — mixed positional + named
hasMany("comments", dependent="delete");
validatesPresenceOf("name", message="Required");

// RIGHT — all named when using options
hasMany(name="comments", dependent="delete");
validatesPresenceOf(properties="name", message="Required");

// RIGHT — positional only (no options)
hasMany("comments");
validatesPresenceOf("name");

2. Query vs Array Confusion in Views

Model finders return query objects, not arrays. Loop accordingly.

// WRONG
<cfloop array="#users#" index="user">

// RIGHT
<cfloop query="users">
    #users.firstName#
</cfloop>

3. Nested Resource Routes — Use Callback Syntax

Wheels supports nested resources via the callback parameter or nested=true with manual end(). Do NOT use Rails-style inline function blocks.

// WRONG — Rails-style inline (not supported)
.resources("posts", function(r) { r.resources("comments"); })

// RIGHT — callback syntax (recommended)
.resources(name="posts", callback=function(map) {
    map.resources("comments");
})

// RIGHT — manual nested=true + end()
.resources(name="posts", nested=true)
    .resources("comments")
.end()

// RIGHT — flat separate declarations (no URL nesting)
.resources("posts")
.resources("comments")

4. HTML5 Form Helpers Available

Wheels provides dedicated HTML5 input helpers. Use them instead of manual type attributes.

// Object-bound helpers
#emailField(objectName="user", property="email")#
#urlField(objectName="user", property="website")#
#numberField(objectName="product", property="quantity", min="1", max="100")#
#telField(objectName="user", property="phone")#
#dateField(objectName="event", property="startDate")#
#colorField(objectName="theme", property="primaryColor")#
#rangeField(objectName="settings", property="volume", min="0", max="100")#
#searchField(objectName="search", property="query")#

// Tag-based helpers
#emailFieldTag(name="email", value="")#
#numberFieldTag(name="qty", value="1", min="0", step="1")#

5. Migration Seed Data — Use Direct SQL

Parameter binding in execute() is unreliable. Use inline SQL for seed data.

// WRONG
execute(sql="INSERT INTO roles (name) VALUES (?)", parameters=[{value="admin"}]);

// RIGHT
execute("INSERT INTO roles (name, createdAt, updatedAt) VALUES ('admin', NOW(), NOW())");

6. Route Order Matters

Routes are matched first-to-last. Wrong order = wrong matches.

Order: MCP routes → resources → custom named routes → root → wildcard (last!)

7. timestamps() Includes createdAt, updatedAt, and deletedAt

Don't also add separate datetime columns for these.

// WRONG — duplicates
t.timestamps();
t.datetime(columnNames="createdAt");

// RIGHT
t.timestamps();  // creates createdAt, updatedAt, AND deletedAt (soft-delete)

Note: t.timestamps() adds three columns, not two — the third is the soft-delete marker. Verified against vendor/wheels/migrator/TableDefinition.cfc.

8. Database-Agnostic Dates in Migrations

Use NOW() — it works across MySQL, PostgreSQL, SQL Server, H2, SQLite.

// WRONG — database-specific
execute("INSERT INTO users (name, createdAt) VALUES ('Admin', CURRENT_TIMESTAMP)");

// RIGHT
execute("INSERT INTO users (name, createdAt, updatedAt) VALUES ('Admin', NOW(), NOW())");

9. Controller Filters Must Be Private

Filter functions (authentication, data loading) must be declared private.

// WRONG — public filter becomes a routable action
function authenticate() { ... }

// RIGHT
private function authenticate() { ... }

10. Always cfparam View Variables

Every variable passed from controller to view needs a cfparam declaration.

// At top of every view file
<cfparam name="users" default="">
<cfparam name="user" default="">

Wheels Conventions

• config(): All model associations/validations/callbacks and controller filters/verifies go in config()
• Naming: Models are singular PascalCase (User.cfc), controllers are plural PascalCase (Users.cfc), table names are plural lowercase (users)
• Parameters: params.key for URL key, params.user for form struct, params.user.firstName for nested
• extends: Models extend "Model", controllers extend "Controller", tests extend "wheels.WheelsTest" (legacy: "wheels.Test" for RocketUnit)
• Associations: All named params when using options: hasMany(name="orders"), belongsTo(name="user"), hasOne(name="profile")
• Validations: Property param is property (singular) for single, properties (plural) for list: validatesPresenceOf(properties="name,email")

Model Quick Reference

component extends="Model" {
    function config() {
        // Table/key (only if non-conventional)
        tableName("tbl_users");
        setPrimaryKey("userId");

        // Associations — all named params when using options
        hasMany(name="orders", dependent="delete");
        belongsTo(name="role");

        // Validations
        validatesPresenceOf("firstName,lastName,email");
        validatesUniquenessOf(property="email");
        validatesFormatOf(property="email", regEx="^[\w\.-]+@[\w\.-]+\.\w+$");

        // Callbacks
        beforeSave("sanitizeInput");

        // Query scopes — reusable, composable query fragments
        scope(name="active", where="status = 'active'");
        scope(name="recent", order="createdAt DESC");
        scope(name="byRole", handler="scopeByRole");  // dynamic scope

        // Enums — named values with auto-generated checkers and scopes
        enum(property="status", values="draft,published,archived");
        enum(property="priority", values={low: 0, medium: 1, high: 2});
    }

    // Dynamic scope handler (must return struct with query keys)
    private struct function scopeByRole(required string role) {
        return {where: "role = '#arguments.role#'"};
    }
}

Finders: model("User").findAll(), model("User").findOne(where="..."), model("User").findByKey(params.key).
Create: model("User").new(params.user) then .save(), or model("User").create(params.user).
Include associations: findAll(include="role,orders"). Pagination: findAll(page=params.page, perPage=25).

Scopes (Composable Query Fragments)

// Chain scopes together — each adds to the query
model("User").active().recent().findAll();
model("User").byRole("admin").findAll(page=1, perPage=25);
model("User").active().recent().count();

Chainable Query Builder (Injection-Safe)

// Fluent alternative to raw WHERE strings — values are auto-quoted
model("User")
    .where("status", "active")
    .where("age", ">", 18)
    .whereNotNull("emailVerifiedAt")
    .orderBy("name", "ASC")
    .limit(25)
    .get();

// Combine with scopes
model("User").active().where("role", "admin").get();

// Other builder methods: orWhere, whereNull, whereBetween, whereIn, whereNotIn

Enums (Named Property Values)

// Auto-generated boolean checkers
user.isDraft();       // true/false
user.isPublished();   // true/false

// Auto-generated scopes per value
model("User").draft().findAll();
model("User").published().findAll();

Batch Processing (Memory-Efficient)

// Process one record at a time (loads in batches internally)
model("User").findEach(batchSize=1000, callback=function(user) {
    user.sendReminderEmail();
});

// Process in batch groups (callback receives query/array)
model("User").findInBatches(batchSize=500, callback=function(users) {
    processUserBatch(users);
});

// Works with scopes and conditions
model("User").active().findEach(batchSize=500, callback=function(user) { /* ... */ });

Middleware Quick Reference

Middleware runs at the dispatch level, before controller instantiation. Each implements handle(request, next).

// config/settings.cfm — global middleware (runs on every request)
set(middleware = [
    new wheels.middleware.RequestId(),
    new wheels.middleware.SecurityHeaders(),
    new wheels.middleware.Cors(allowOrigins="https://myapp.com")
]);

// config/routes.cfm — route-scoped middleware
mapper()
    .scope(path="/api", middleware=["app.middleware.ApiAuth"])
        .resources("users")
    .end()
.end();

Built-in: wheels.middleware.RequestId, wheels.middleware.Cors, wheels.middleware.SecurityHeaders, wheels.middleware.RateLimiter. Custom middleware: implement wheels.middleware.MiddlewareInterface, place in app/middleware/.

DI Container Quick Reference

Register services in config/services.cfm (loaded at app start, environment overrides supported):

var di = injector();
di.map("emailService").to("app.lib.EmailService").asSingleton();
di.map("currentUser").to("app.lib.CurrentUserResolver").asRequestScoped();
di.bind("INotifier").to("app.lib.SlackNotifier").asSingleton();

Resolve with service() anywhere, or use inject() in controller config():

// In any controller/view
var svc = service("emailService");

// Declarative injection in controller config()
function config() {
    inject("emailService, currentUser");
}
function create() {
    this.emailService.send(to=user.email);  // resolved per-request
}

Scopes: transient (default, new each call), .asSingleton() (app lifetime), .asRequestScoped() (per-request via request.$wheelsDICache). Auto-wiring: init() params matching registered names are auto-resolved when no initArguments passed. bind() = semantic alias for map().

Rate Limiting

// Fixed window (default) — 60 requests per 60 seconds
new wheels.middleware.RateLimiter()

// Sliding window — smoother enforcement
new wheels.middleware.RateLimiter(maxRequests=100, windowSeconds=120, strategy="slidingWindow")

// Token bucket — allows bursts up to capacity, refills steadily
new wheels.middleware.RateLimiter(maxRequests=50, windowSeconds=60, strategy="tokenBucket")

// Database-backed storage (auto-creates wheels_rate_limits table)
new wheels.middleware.RateLimiter(storage="database")

// Custom key function (rate limit per API key instead of IP)
new wheels.middleware.RateLimiter(keyFunction=function(req) {
    return req.cgi.http_x_api_key ?: "anonymous";
})

Strategies: fixedWindow (default), slidingWindow, tokenBucket. Storage: memory (default) or database. Adds X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset headers. Returns 429 Too Many Requests with Retry-After when limit exceeded.

Package System

Optional first-party modules are distributed as standalone repositories and installed into vendor/<name>/. The framework auto-discovers vendor/*/package.json on startup via PackageLoader.cfc with per-package error isolation.

Public author-facing guide: Packages — manifest fields, mixin targets, lifecycle, service providers, lazy loading, testing, publishing flow. Submission workflow: wheels-packages/CONTRIBUTING.md.

Six first-party packages live in standalone repos under wheels-dev/, indexed by the wheels-dev/wheels-packages registry:

• wheels-dev/wheels-sentry — error tracking
• wheels-dev/wheels-hotwire — Turbo/Stimulus
• wheels-dev/wheels-basecoat — UI components
• wheels-dev/wheels-legacy-adapter — 3.x → 4.x compatibility shims
• wheels-dev/wheels-i18n — internationalization (JSON or DB-backed translations, pluralization)
• wheels-dev/wheels-seo-suite — SEO tooling (meta tags, Open Graph, sitemaps, robots.txt, debug panel)

vendor/                # Runtime: framework core + installed packages
  wheels/              #   Framework core (excluded from package discovery)
  wheels-sentry/       #   Installed package
plugins/               # DEPRECATED: legacy plugins still work with warning

package.json Manifest

{
    "name": "wheels-sentry",
    "version": "1.0.0",
    "author": "PAI Industries",
    "description": "Sentry error tracking",
    "wheelsVersion": ">=3.0",
    "provides": {
        "mixins": "controller",
        "services": [],
        "middleware": []
    },
    "dependencies": {}
}

provides.mixins: Comma-delimited targets from the allowlist application,dispatch,controller,mapper,model,base,sqlserver,mysql,postgresql,h2,test, plus the special values global (inject into all targets) and none (explicit opt-out). Determines which framework components receive the package's public methods. Default: none (explicit opt-in, unlike legacy plugins which default to global). Unknown targets (typos, view, service, etc.) are rejected with a clear error — view helpers belong in controller mixins since Wheels views execute in the controller's variables scope.

Installing a Package

Use the wheels packages CLI. Resolves names against the wheels-dev/wheels-packages registry, verifies sha256, extracts to vendor/<name>/.

wheels packages list                          # browse the registry
wheels packages search <query>                # name/description/tag match
wheels packages show <name>                   # detail page
wheels packages add <name>                    # latest compat version (canonical verb)
wheels packages add <name>@<version>          # pin
wheels packages add <name> --force            # overwrite an existing vendor/<name>
wheels packages update <name> --yes           # explicit update
wheels packages update --all --yes            # update every installed package
wheels packages remove <name>                 # delete vendor/<name>
wheels packages registry refresh              # bust the 24h cache
wheels packages registry info                 # show registry URL + cache state

Override the registry with WHEELS_PACKAGES_REGISTRY=<org>/<repo> (defaults to wheels-dev/wheels-packages). Restart or wheels reload after install.

Error Isolation

Each package loads in its own try/catch. A broken package is logged and skipped — the app and other packages continue normally.

Testing Packages

# Run a specific package's tests (package must be in vendor/)
curl "http://localhost:60007/wheels/core/tests?db=sqlite&format=json&directory=vendor.wheels-sentry.tests"

Routing Quick Reference

// config/routes.cfm
mapper()
    .resources("users")                              // standard CRUD
    .resources("products", except="delete")           // skip actions
    .resources(name="posts", callback=function(map) { // nested resources
        map.resources("comments");
        map.resources("tags");
    })
    .get(name="login", to="sessions##new")           // named route
    .post(name="authenticate", to="sessions##create")
    .root(to="home##index", method="get")            // homepage
    .wildcard()                                       // keep last!
.end();

Helpers: linkTo(route="user", key=user.id, text="View"), urlFor(route="users"), redirectTo(route="user", key=user.id), startFormTag(route="user", method="put", key=user.id).

Route Model Binding

Automatically resolves params.key into a model instance before the controller action runs. The instance lands in params.<singularModelName> (e.g., params.user). Throws Wheels.RecordNotFound (404) if the record doesn't exist; silently skips if the model class doesn't exist.

// Per-resource — convention: singularize controller name → model
.resources(name="users", binding=true)

// Explicit model name override
.resources(name="posts", binding="BlogPost")  // resolves BlogPost, stored in params.blogPost

// Scope-level — all nested resources inherit binding
.scope(path="/api", binding=true)
    .resources("users")     // params.user
    .resources("products")  // params.product
.end()

// Global — enable for all resource routes
set(routeModelBinding=true);  // in config/settings.cfm

In the controller, use the resolved instance directly:

function show() {
    user = params.user;  // already a model object, no findByKey needed
}

Pagination View Helpers

Requires a paginated query: findAll(page=params.page, perPage=25). The recommended all-in-one helper is paginationNav().

// All-in-one nav (wraps first/prev/page-numbers/next/last in <nav>)
#paginationNav()#
#paginationNav(showInfo=true, showFirst=false, showLast=false, navClass="my-pagination")#

// Individual helpers for custom layouts
#paginationInfo()#            // "Showing 26-50 of 1,000 records"
#firstPageLink()#             // link to page 1
#previousPageLink()#          // link to previous page
#pageNumberLinks()#           // windowed page number links (default windowSize=2)
#nextPageLink()#              // link to next page
#lastPageLink()#              // link to last page
#pageNumberLinks(windowSize=5, classForCurrent="active")#

Disabled links render as <span class="disabled"> by default. All helpers accept handle for named pagination queries.

Testing Quick Reference

All new tests use WheelsTest BDD syntax. RocketUnit (test_ prefix, assert()) is legacy only — never use it for new tests.

Two test suites

• App tests: /wheels/app/tests — project-specific tests in tests/specs/. Uses tests/populate.cfm for test data and tests/TestRunner.cfc for setup.
• Core tests: /wheels/core/tests — framework tests in vendor/wheels/tests/specs/. Uses vendor/wheels/tests/populate.cfm. This is what CI runs across all engines × databases.

Critical: Core tests use directory="wheels.tests.specs" which compiles EVERY CFC in the directory. One compilation error in any spec file crashes the entire suite for that engine.

// tests/specs/models/MyFeatureSpec.cfc
component extends="wheels.WheelsTest" {
    function run() {
        describe("My Feature", () => {
            it("validates presence of name", () => {
                var user = model("User").new();
                expect(user.valid()).toBeFalse();
            });
        });
    }
}

• Specs: tests/specs/models/, tests/specs/controllers/, tests/specs/functional/
• Test models: tests/_assets/models/ (use table() to map to test tables)
• Test data: tests/populate.cfm (DROP + CREATE tables, seed data)
• Runner URL: /wheels/app/tests?format=json&directory=tests.specs.models
• Force reload: append &reload=true after adding new model CFCs
• Closure gotcha: CFML closures can't access outer local vars — use shared structs (var result = {count: 0})
• Scope gotcha in test infra: Wheels internal functions ($dbinfo, model(), etc.) aren't available as bare calls in .cfm files included from plain CFCs like TestRunner.cfc. Use application.wo.model() or native CFML tags (cfdbinfo).
• # escape gotcha: HTML entities like o contain # which CFML interprets as expression delimiters. In string literals, escape as &##111;. Comments (//) are fine since they aren't evaluated. Unescaped # in strings causes "Invalid Syntax Closing [#] not found" compilation errors that crash the entire test suite (not just that file).
• $clearRoutes() in test specs: Test CFCs that manipulate routes must define their own $clearRoutes() method — it is NOT inherited from wheels.WheelsTest. Copy from linksSpec.cfc.
• Left(str, 0) crashes Lucee 7: Use a ternary guard: local.match.pos[1] > 1 ? Left(str, local.match.pos[1] - 1) : ""
• Run with MCP wheels_test() or CLI wheels test run

Running Tests Locally (Wheels CLI — Recommended)

IMPORTANT: Always run the test suite before pushing. Do not rely on CI alone.

wheels IS the CLI. Wheels is built on the LuCLI runtime, but we ship the runtime under the wheels brand. End users only ever interact with the CLI as wheels — there is no separate lucli binary on a normal install. When older docs or scripts mention "install LuCLI" or invoke lucli, they pre-date the rebrand and are being migrated to wheels.

Fastest method: one command

bash tools/test-local.sh              # run all core tests
bash tools/test-local.sh model        # run model tests only
bash tools/test-local.sh security     # run security tests only

The script handles everything: creates SQLite DBs, starts a Wheels CLI server if needed, runs tests, reports results, cleans up. No Docker required.

Prerequisites (one-time setup)

# Install the Wheels CLI (4.0.0+ recommended)
brew install wheels   # or download from GitHub releases
# Java 21 required
brew install openjdk@21

Manual method (if you need a persistent server)

cd /path/to/wheels
sqlite3 wheelstestdb.db "SELECT 1;"
sqlite3 wheelstestdb_tenant_b.db "SELECT 1;"
wheels start --port=8080

# In another terminal:
curl -s "http://localhost:8080/?reload=true&password=wheels"
curl -sf "http://localhost:8080/wheels/core/tests?db=sqlite&format=json" | \
  python3 -c "import json,sys; d=json.load(sys.stdin); print(f'{d[\"totalPass\"]} pass, {d[\"totalFail\"]} fail, {d[\"totalError\"]} error')"

Run specific test directories

bash tools/test-local.sh model        # vendor/wheels/tests/specs/model/
bash tools/test-local.sh controller   # vendor/wheels/tests/specs/controller/
bash tools/test-local.sh view         # vendor/wheels/tests/specs/view/

bash tools/test-local.sh migrator     # vendor/wheels/tests/specs/migrator/

Running Tests Locally (Docker matrix)

Docker is the authoritative way to reproduce CI's compat-matrix.yml workflow
(every engine × every database) before pushing. Source is bind-mounted via
compose.yml at ./:/wheels-test-suite, so edit-reload-test
cycles don't require image rebuilds — only the Wheels application reloads
between iterations.

tools/test-matrix.sh — local mirror of compat-matrix.yml

tools/test-matrix.sh                       # Lucee 7 + SQLite (happy path, fastest)
tools/test-matrix.sh lucee7 mysql          # Lucee 7 + MySQL
tools/test-matrix.sh lucee7 sqlite,mysql   # Multiple DBs against one engine
tools/test-matrix.sh lucee6,lucee7 sqlite  # Multiple engines against one DB
tools/test-matrix.sh --all                 # Full matrix (every engine × every DB)
tools/test-matrix.sh --rebuild lucee7      # Force `docker compose build` (image cache stale)
tools/test-matrix.sh --down                # Tear everything down

Mirrors CI exactly: engine + DB containers come up under
COMPOSE_PROJECT_NAME=wheels (so containers are named wheels-<service>-1,
matching every assertion in compat-matrix.yml); engine restarts between DB
runs to clear cached model metadata; warmup curl before each test run; same
test URL (/wheels/core/tests?db=<db>&format=json); same JSON parsing.

Default behavior: containers stay running between invocations (fast iteration
for repeated runs against the same engine/DB). Edit framework code → --reload
isn't needed if you're hitting the test endpoint, since wheels/core/tests
re-evaluates each request. For full app reload (model metadata, package
discovery): curl "http://localhost:<port>/?reload=true&password=wheels".

Engines and ports (mirror compat-matrix.yml matrix)

Engine	Port
lucee6	60006
lucee7	60007
adobe2023	62023
adobe2025	62025
boxlang	60001

compose.yml also defines lucee5, adobe2018, adobe2021 services for
historical reasons; they are NOT in the CI matrix and should be considered
unsupported for new development.

Databases (mirror compat-matrix.yml DATABASES env)

sqlite, h2 (Lucee only), mysql, postgres, sqlserver, cockroachdb,
oracle. SQLite and H2 are file-based (no container needed). The rest spawn
their own service containers.

Manual ad-hoc invocations (skip the wrapper)

If you want to script something the wrapper doesn't cover, the underlying
moves are documented in .github/workflows/compat-matrix.yml.
Always set COMPOSE_PROJECT_NAME=wheels first so container names match CI.

export COMPOSE_PROJECT_NAME=wheels
docker compose up -d lucee7 mysql
# wait for ready (see compat-matrix.yml lines 79-124 for canonical readiness check)
curl -s "http://localhost:60007/wheels/core/tests?db=mysql&format=json&directory=tests.specs.controller" > /tmp/results.json

Known cross-engine gotchas

Always verify Adobe CF fixes locally before pushing — don't iterate via CI. Test against the local container directly:

curl -s "http://localhost:62023/wheels/core/tests?db=mysql&format=json" | \
  python3 -c "import json,sys; d=json.load(sys.stdin); print(d.get('totalPass',0),'pass',d.get('totalFail',0),'fail',d.get('totalError',0),'error')"

• struct.map(): Lucee/Adobe resolve obj.map() as the built-in struct member function, not the CFC method. Use mapInstance() on the Injector.
• Application scope: Adobe CF doesn't support function members on the application scope. Pass a plain struct context instead.
• Closure this: CFML closures capture this from the declaring scope. Use var ctx = {ref: obj} to share references across closures.
• Bracket-notation function call: obj["key"]() crashes Adobe CF 2021/2023 parser inside closures. Split into two statements: var fn = obj["key"]; fn().
• Inline closure as constructor named arg: new Foo(callback = function(){...}) crashes Adobe CF with ArrayStoreException: ASTcffunction and takes down the entire TestBox bundle because getComponentMetadata() triggers eager compilation of every CFC in the directory. Hoist the closure into a local var first: var fn = function(){...}; new Foo(callback = fn). No behavior change on Lucee/BoxLang.
• Array by-value in struct literals: Adobe CF copies arrays by value in {arr = myArray}. Closures that append to the copy won't affect the original. Reference via parent struct instead: {owner = parentStruct} then owner.arr.
• private mixin functions not integrated: $integrateComponents() only copies public methods into model/controller objects. ALL helper functions in mixin CFCs (vendor/wheels/model/*.cfc, view helpers, etc.) MUST use public access. Use $ prefix for internal scope instead of private keyword. BoxLang handles this differently, so private may pass BoxLang tests but fail Lucee/Adobe.

CI soft-fail databases

SOFT_FAIL_DBS in .github/workflows/compat-matrix.yml (lines 389, 519) is currently empty ("") — all databases, including CockroachDB, are hard-gated in CI. To mark a database as soft-fail (failures logged as warnings but not blocking the build), add it to SOFT_FAIL_DBS in both locations. Remove a database from the list once its tests are fixed.

Cleanup

tools/test-matrix.sh --down    # Stop and remove all containers + network

Local Onboarding Harness

tools/test-onboarding.sh simulates the brand-new-user fresh-install flow without
touching the user's daily wheels install. It is the right tool when:

• Fixing CLI / framework / template code that affects the wheels new →
  wheels start → wheels migrate latest cliff.
• Validating cliff fixes BEFORE asking for a fresh-VM tutorial run.
• Iterating on dotted-path resolution, Lucee bundle issues, or generated
  config emission.

bash tools/test-onboarding.sh             # symlink-mount worktree (default)
MODE=copy bash tools/test-onboarding.sh   # closer to brew-install simulation
BASELINE=1 bash tools/test-onboarding.sh  # use the brew-installed wheels
KEEP_TEMP=1 bash tools/test-onboarding.sh # preserve temp dirs for inspection
FROM_PHASE=4 bash tools/test-onboarding.sh # skip earlier phases when iterating

The harness uses LUCLI_HOME isolation (writes only into mktemp -d), reuses
the user's existing Lucee Express via symlink to skip the ~74MB redownload, and
runs ~90 seconds end-to-end through 7 phases mirroring the fresh-VM onboarding
journal format. Output is directly comparable to fresh-VM run reports.

Phase	Covers	Fresh-VM findings
1	Setup isolated LUCLI_HOME, framework path, Lucee Express symlink	—
2	wheels new (no duplicate create lines, file tree, no bundleName)	F1, F3, F4
3	Server boot via wheels start + sqlite-jdbc shim	(formula simulation)
4	Migration cliff — verify the actual sqlite db has tables, not just exit 0	F2, F5
5	Seed (cfscript wrapper + seedOnce idempotency)	F3-orig
6	CRUD walkthrough (tutorial chapters 2-3 happy path)	tutorial verification
7	wheels packages list	F7 (currently SKIP pending follow-up)

Output uses ✓ / ✗ / - per check. A green local run is a strong predictor
of a green fresh-VM run; the SKIP markers signal known pending issues that are
expected to fail until their respective follow-up PRs ship.

Auto-Migration Quick Reference

Generate migrations from model/DB schema diffs. Rename detection via explicit hints (authoritative) + heuristic suggestions (normalized-token + Levenshtein).

// Programmatic
var am = CreateObject("component", "wheels.migrator.AutoMigrator");

// Single model
var d = am.diff("User");
var d = am.diff("User", {renames: {"full_name": "fullName"}});
var d = am.diff("User", {heuristicThreshold: 0.85});

// All models (per-model hints keyed by model name)
var all = am.diffAll({
    hints: {"User": {renames: {"full_name": "fullName"}}},
    heuristicThreshold: 0.7
});

// Write migration CFC from diff result
am.writeMigration(d, "rename_name_field");

# CLI
wheels dbmigrate diff User                                    # preview
wheels dbmigrate diff User --rename=full_name:fullName        # with hint
wheels dbmigrate diff User --write --name=rename_name         # commit file
wheels dbmigrate diff --threshold=0.85                        # all models, stricter
wheels dbmigrate diff --rename=User.full_name:fullName        # diffAll hint

Diff result struct:

{modelName, tableName,
 addColumns, removeColumns, changeColumns,        // pruned of rename pairs
 renameColumns,       // confirmed renames (emitted into up/down)
 suggestedRenames}    // heuristic candidates for display

Limits: PK renames not detected; rename + type change requires separate migrations; calculated properties excluded from diff.

Database Seeding Quick Reference

Convention-based, idempotent seeding with CLI support.

// app/db/seeds.cfm — Shared seeds (runs in all environments)
seedOnce(modelName="Role", uniqueProperties="name", properties={
    name: "admin", description: "Administrator"
});
seedOnce(modelName="Role", uniqueProperties="name", properties={
    name: "member", description: "Regular member"
});

// app/db/seeds/development.cfm — Dev-only seeds (runs after seeds.cfm)
seedOnce(modelName="User", uniqueProperties="email", properties={
    firstName: "Dev", lastName: "User", email: "dev@example.com"
});

CLI (canonical Wheels CLI form; wheels db:seed is the legacy CommandBox alias — prefer the short form):

wheels seed                             # Run convention seeds (auto-detect env)
wheels seed --environment=production    # Seed for specific environment
wheels seed --generate                  # Legacy: random test data
wheels generate seed                    # Create app/db/seeds.cfm
wheels generate seed --all              # Create seeds.cfm + dev/prod stubs

Note: the --count / --models / --dataFile flags on --generate only exist on the legacy CommandBox wheels db:seed surface; the Wheels CLI's wheels seed ignores them.

seedOnce() — idempotent: checks uniqueProperties via findOne(), creates only if not found. Re-running seeds is always safe.

Execution order: app/db/seeds.cfm (shared) → app/db/seeds/<environment>.cfm (env-specific). Wrapped in a transaction.

Seeder component: application.wheels.seeder (initialized alongside migrator). Call application.wheels.seeder.runSeeds() programmatically.

Background Jobs Quick Reference

// Define a job: app/jobs/SendWelcomeEmailJob.cfc
component extends="wheels.Job" {
    function config() {
        super.config();
        this.queue = "mailers";
        this.maxRetries = 5;
    }
    public void function perform(struct data = {}) {
        sendEmail(to=data.email, subject="Welcome!", from="app@example.com");
    }
}

// Enqueue from a controller
job = new app.jobs.SendWelcomeEmailJob();
job.enqueue(data={email: user.email});           // immediate
job.enqueueIn(seconds=300, data={email: "..."});  // delayed 5 minutes
job.enqueueAt(runAt=scheduledDate, data={});       // at specific time

// Process jobs (call from scheduled task or controller)
job = new wheels.Job();
result = job.processQueue(queue="mailers", limit=10);

// Queue management
stats = job.queueStats();          // {pending, processing, completed, failed, total}
job.retryFailed(queue="mailers");  // retry all failed jobs
job.purgeCompleted(days=7);        // clean up old completed jobs

Job Worker CLI — persistent daemon for processing jobs:

wheels jobs work                           # process all queues
wheels jobs work --queue=mailers --interval=3  # specific queue, 3s poll
wheels jobs status                         # per-queue breakdown
wheels jobs status --format=json           # JSON output
wheels jobs retry --queue=mailers          # retry failed jobs
wheels jobs purge --completed --failed --older-than=30
wheels jobs monitor                        # live dashboard

Configurable backoff: this.baseDelay = 2 and this.maxDelay = 3600 in job config(). Formula: Min(baseDelay * 2^attempt, maxDelay).

The wheels_jobs table is auto-created by Job.cfc::$ensureJobTable() on first enqueue or processing — no migration needed. (The older 20260221000001_createwheels_jobs_table.cfc migration is vestigial; Phase 2b drift audit confirmed auto-create is now the path.)

Deploy Quick Reference

wheels deploy ships your Dockerized Wheels app to production Linux servers via SSH. Ported from Basecamp Kamal's developer CLI — same config/deploy.yml schema, same on-server conventions (container names, labels, network, lock path), invokes the same kamal-proxy Go binary for zero-downtime rollover. No Ruby runtime required.

wheels deploy init                     # scaffold config/deploy.yml + .kamal/secrets
wheels deploy setup                    # one-time server bootstrap + first deploy
wheels deploy                          # rolling deploy
wheels deploy --dry-run                # print commands without executing
wheels deploy rollback v1              # roll back to a previous version
wheels deploy config                   # print resolved config as YAML
wheels deploy version                  # show Kamal version this port mirrors

On-server parity contract (byte-compatible with Ruby Kamal)

• Container names: <service>-<role>-<version>
• Labels: service=, role=, destination=, version=
• Docker network: kamal
• Lock file: /tmp/kamal_deploy_lock_<service>
• Proxy config: /home/<user>/.config/kamal-proxy/
• Hook env prefix: KAMAL_* (never WHEELS_* — user hooks migrate unchanged)

A server managed by Ruby Kamal can be taken over by wheels deploy without cleanup.

Commands-are-strings invariant: every *Commands.cfc method returns a shell-command string; only *Cli.cfc and the orchestrator execute them. That's why --dry-run is trivial and unit tests run without network.

Critical gotchas

1. Kamal-compatible schema, ONE divergence. ERB in deploy.yml is NOT supported (rendering it would require embedding a Ruby runtime). Kamal's native ${VAR} env-var interpolation is preserved unchanged — uppercase-snake tokens resolve via envOverride → .kamal/secrets → System.getenv → "" (see ConfigLoader.$interpolate). Mustache ({{...}}) is used only by wheels deploy init to scaffold a fresh deploy.yml/secrets; it is NOT applied to deploy.yml at runtime. Everything else in config/deploy.yml is byte-identical to Kamal 2.4.0.
2. Hook env prefix is KAMAL_, not WHEELS_. This is deliberate — it means Ruby Kamal users' existing .kamal/hooks/ scripts work unchanged.
3. app live / app maintenance use a marker file (/tmp/kamal-maintenance-<svc>) rather than kamal-proxy native maintenance mode. Phase 2 simplification; Phase 3 follow-up will align with Kamal's proxy-native semantics.
4. wheels deploy remove is destructive and requires --confirm. Bare wheels deploy remove throws without touching anything.
5. Lucee reserved scope names in subagent-authored deploy code. client, session, application — use ssh/sc, sess, app instead. Bit us multiple times during the port.
6. No --dry-run flag in Ruby Kamal 2.4.0. The tools/deploy-config-diff.sh harness compares config-layer output only. Byte-identical command-string parity is aspirational; see tools/deploy-dry-run-diff.sh for the plan.

Testing

cli/lucli/tests/specs/deploy/ extends wheels.wheelstest.system.BaseSpec. Run with:

bash tools/test-cli-local.sh

Fixtures at cli/lucli/tests/_fixtures/deploy/configs/ (minimal.yml, full.yml, with-accessories.yml, invalid/*.yml). FakeSshPool.cfc records every command for offline assertions; no sshd needed for unit tests. SshClientSpec + SshPoolSpec exercise real SSH via the fixture at cli/lucli/tests/_fixtures/deploy/sshd/ (brought up by tools/deploy-sshd-up.sh).

Server-Sent Events (SSE) Quick Reference

// In a controller action — single event response
function notifications() {
    var data = model("Notification").findAll(where="userId=#params.userId#");
    renderSSE(data=SerializeJSON(data), event="notifications", id=params.lastId);
}

// Streaming multiple events (long-lived connection)
function stream() {
    var writer = initSSEStream();
    for (var item in items) {
        sendSSEEvent(writer=writer, data=SerializeJSON(item), event="update");
    }
    closeSSEStream(writer=writer);
}

// Check if request is from EventSource
if (isSSERequest()) { renderSSE(data="..."); }

Client-side: const es = new EventSource('/controller/notifications');

Browser Testing Quick Reference

Shipped in v4.0 across PRs #2113, #2115, #2116. Specs extend wheels.wheelstest.BrowserTest and drive a real Chromium through this.browser — a fluent DSL wrapping Playwright Java.

// vendor/wheels/tests/specs/browser/LoginBrowserSpec.cfc
component extends="wheels.wheelstest.BrowserTest" {

    this.browserEngine = "chromium";   // chromium only in PR 1

    function run() {
        // browserDescribe() wraps describe() with beforeEach/afterEach that
        // create a fresh Page per `it`. WheelsTest's BDD lifecycle only treats
        // beforeAll/afterAll as class-level, so we register per-it hooks
        // from inside the suite body via this helper.
        browserDescribe("Login flow", () => {
            it("can load a page and read its title", () => {
                if (this.browserTestSkipped) return;
                this.browser.visitUrl("data:text/html,<title>Hi</title><h1>x</h1>")
                            .assertTitleContains("Hi");
            });
        });
    }
}

Install Playwright locally before first run (~370MB download: JARs + Chromium):

wheels browser setup              # downloads JARs + Chromium

Then run browser specs via the normal test suite:

bash tools/test-local.sh                    # skips browser specs if JARs missing

Implemented DSL methods

• Navigation: visit, visitUrl, back, forward, refresh, visitRoute
• Interaction: click, press, fill, type, clear, select, check, uncheck, attach, dragAndDrop
• Keyboard: keys, pressEnter, pressTab, pressEscape
• Waiting: waitFor, waitForText, waitForUrl
• Scoping: within(selector, callback)
• Cookies: setCookie, deleteCookie, cookie, clearCookies
• Auth: loginAs, logout
• Dialogs: acceptDialog, dismissDialog, dialogMessage (Lucee-only via createDynamicProxy)
• Viewport: resize, resizeToMobile, resizeToTablet, resizeToDesktop
• Script: script (returns page.evaluate result), pause
• Assertions (text/vis/presence): assertSee, assertDontSee, assertSeeIn, assertVisible, assertMissing, assertPresent, assertNotPresent
• Assertions (URL/title/query): assertUrlIs, assertUrlContains, assertTitleContains, assertQueryStringHas, assertQueryStringMissing, assertRouteIs
• Assertions (form): assertInputValue, assertChecked, assertHasClass
• Terminals: currentUrl, title, pageSource, text, value, screenshot

Key gotchas

• ## in selectors — CFML requires ## to emit literal #. "##email" → "#email" at runtime.
• client is a Lucee reserved scope. var client = ... in a closure throws "client scope is not enabled". Use var c = ... or var bc = ....
• Data URLs work for most tests — no server needed for ~95% of DSL coverage. Full HTTP integration (cookies, form submits, redirects) needs a running fixture app; that wiring is the same as Wheels Web app bootstrap (separate server + baseUrl).
• this.browserTestSkipped — when Playwright JARs aren't installed (fresh CI, clean machine), beforeAll sets this flag and browserDescribe's hooks short-circuit. All its should check if (this.browserTestSkipped) return; to stay green on CI.
• CI runs browser tests — pr.yml and snapshot.yml install Playwright JARs + Chromium (cached via browser-manifest.json hash). Browser specs run as part of the normal test suite. WHEELS_BROWSER_TEST_BASE_URL=http://localhost:60007 is set automatically.
• Fixture routes — /_browser/login-as and /_browser/logout are mounted automatically in test mode. They must come before .wildcard() in routes.cfm. In the Routes UI (/wheels/routes) all /_browser/* routes appear under the Internal tab, not Application.
• Dialogs are Lucee-only — acceptDialog, dismissDialog, dialogMessage use createDynamicProxy which is Lucee-specific. Specs skip gracefully on other engines.

Commit Message Conventions

This repo uses commitlint. The canonical rules live in commitlint.config.js; this section reflects them. If the two ever disagree, the config wins.

Format

type(scope): subject — scope is optional.

• type is required.
• scope is optional and unrestricted. Pick a short noun that helps a reader skim git log (e.g. model, cli, web/blog), or omit it entirely. There is no allowlist — pick what fits.
• subject is required, must not be empty, must not be ALL-CAPS, and the full header must be ≤ 100 chars.

Valid types

feat, fix, docs, style, refactor, perf, test, build, ci, chore, revert.

Suggested scopes (not enforced)

These are common scopes used in this repo. None are required, and you can use scopes outside this list freely.

• Framework layers: model, controller, view, router, middleware, migration, cli, test, config, di, job, mailer, plugin, sse, seed, docs
• Static-site monorepo (under web/): web, web/ui, web/landing, web/blog, web/guides, web/api, web/packages

Subject rules

• Must not be empty.
• Must not be ALL-CAPS (e.g., fix: FIX BUG is rejected).
• Sentence-case, start-case, and pascal-case are allowed — proper nouns like Giscus, CockroachDB, Buttondown keep their canonical capitalization.
• Header (type(scope): subject) capped at 100 chars.

Branding

The project name is Wheels (not "CFWheels"). The rebrand happened at v3.0. Always use "Wheels" in new code, comments, commit messages, PR descriptions, and documentation.

MCP Server

Canonical surface (Wheels 4.0+): the Wheels CLI's stdio MCP server at wheels mcp wheels. Configure your AI IDE with:

{"mcpServers":{"wheels":{"command":"wheels","args":["mcp","wheels"]}}}

Or run wheels mcp setup to generate .mcp.json + .opencode.json automatically.

Tools are auto-discovered from cli/lucli/Module.cfc public functions, prefixed with the module name (wheels_generate, wheels_migrate, wheels_test, wheels_reload, wheels_seed, wheels_analyze, wheels_validate, wheels_routes, wheels_info, wheels_destroy, wheels_doctor, wheels_stats, wheels_notes, wheels_db, wheels_upgrade, wheels_create, wheels_deploy). CLI-only tools (mcp, d, new, console, start, stop, browser) are hidden from MCP tools/list via mcpHiddenTools().

Workflow orchestration (multi-step planning, feature development) is not a framework concern — use your preferred Claude Code plugin (Superpowers, feature-dev, etc.). The framework ships deterministic Wheels operations via MCP; the model orchestrates.

Deprecated: The in-dev-server HTTP endpoint at /wheels/mcp (routed from vendor/wheels/public/views/mcp.cfm). Emits a deprecation notice and warning log on first request. Scheduled for removal in a future release — migrate to the stdio surface. See docs/command-line-tools/commands/mcp/mcp-configuration-guide.md.

Marker conventions (HTML comments, used for idempotency):

• <!-- wheels-bot:triage:<issue> --> + <!-- wheels-bot:triage-class:<bug|framework-design|other> --> (+ optional <!-- wheels-bot:triage-confidence:high|medium --> — either fires propose-fix; low omitted)
• <!-- wheels-bot:research:<issue> --> (+ optional <!-- wheels-bot:research-confidence:high|medium --> — either fires propose-fix; low omitted)
• <!-- wheels-bot:fix:<issue> --> / <!-- wheels-bot:fix-held:<issue> -->
• <!-- wheels-bot:review-a:<pr>:<sha> -->
• <!-- wheels-bot:review-b:<pr>:<sha>:<round> -->
• <!-- wheels-bot:auto-close:<issue> -->

Allow-listed scopes per stage: every bot-authored commit must conform to the commitlint.config.js allowlist (see § Commit Message Conventions). The bot's prompt (.claude/commands/_shared-rails.md) re-states the allowlist verbatim.

Kill switch: flip the repo variable WHEELS_BOT_ENABLED to false to halt every bot workflow without code changes. Add the [skip-claude] label (or [skip-claude] in the title) to halt activity on a single issue/PR.

Auto-fire safety net: the bot is permitted to chain stages (triage → research → propose-fix), and handoff fires on *-confidence:high OR *-confidence:medium. Low stays manual. Sensitive areas (security, middleware, migrations, deploy, DI, cross-engine) are caught by the propose-fix prompt's own step-4 safety net, which posts a fix-held marker instead of opening a PR. Reviewer A and B then critique whatever propose-fix produces, escalating to the Senior Advisor on deadlock. All bot PRs land as --draft and require a human approving review on develop.

Wheels Bot — Reviewer B (round 1)

Reviewer A's submission (review ID 4286590018, state: COMMENTED) contains no substantive analysis. The review body is the verbatim contents of CLAUDE.md (54,531 characters of project documentation) with zero line comments attached. This is a system-prompt leak — the model context was written out as the review body instead of actual review prose. The PR therefore has received no effective code review from Reviewer A.

Sycophancy

• Not applicable: Reviewer A produced no verdict, no approval, no LGTM, and no inline findings. The review body is entirely non-review content (CLAUDE.md dump).

False positives

• Not applicable: Reviewer A raised no findings to evaluate.

Missed issues

Since Reviewer A produced nothing, I'll note what a correct review should have caught:

• compat-matrix.yml line ~131: curl ... 2>/dev/null || true — the || true is the right guard here (prevents set -e exit on curl failure). The companion comment explaining why || echo "000" would be wrong is correct and helpful. No issue.
• Stack-frame filter regex ^\s*at\s|runwar\.context -[[:space:]]+at[[:space:]] is Lucee/runwar-specific. On Adobe CF and BoxLang, stack frames take different forms, so the filtered output may still be noisy on those engines. This is a minor gap — the raw tail-200 fallback is present, so diagnosis is still possible. Worth noting in a follow-up.
• The head -c 500 body sample could truncate mid-UTF-8 sequence and produce garbled output, but for diagnostic shell output this is acceptable.
• CHANGELOG.md entry is one long run-on sentence (~200 chars). Cosmetically awkward but not a blocker.
• No .ai/wheels/ documentation updates are needed — this is a CI workflow change only, not a behavior change to the framework.
• Commit message ci(compat-matrix): make CF engine readiness diagnostics actionable on timeout is well-formed: valid type ci, optional scope compat-matrix, subject ≤ 100 chars, not ALL-CAPS. Commitlint passes.
• No security, migration, deploy, DI, or cross-engine framework subsystems are touched. The workflow-injection hardening (env: CFENGINE: + $CFENGINE in shell) is correct and follows GitHub's recommended pattern.

Verdict alignment

There is no verdict from Reviewer A to align or disagree with — the review was a system malfunction.

Convergence

Cannot converge with a null review. The PR itself looks CI-maintenance clean: a pure diagnostic improvement to compat-matrix.yml with no framework code changes, correct commitlint compliance, and reasonable shell hygiene. A human reviewer should re-trigger Reviewer A or approve directly. Reviewer B does not unilaterally approve.

Wheels Bot — Reviewer A response (round 1)

My initial submission (review ID 4286590018) was a system-prompt leak — the model wrote out CLAUDE.md verbatim instead of producing a review. B correctly identified this as a malfunction and supplied the substantive analysis that should have come from me. I concede that failure entirely, and I have now read the actual diff to engage with B's findings properly.

After reviewing .github/workflows/compat-matrix.yml and CHANGELOG.md:

Conceded points

• System-prompt leak: B's characterisation is accurate. My prior submission contained zero review content. No findings, no verdict, no inline comments.
• curl ... 2>/dev/null || true is correct: The || true prevents set -e exit when curl returns non-zero. The comment in the diff correctly explains why || echo "000" would be wrong (concatenation with curl's own "000" output). B's assessment stands.
• Stack-frame filter is Lucee/runwar-specific: grep -vE '^\s*at\s|runwar\.context -[[:space:]]+at[[:space:]]' targets runwar stack frames. Adobe CF and BoxLang emit different Java stack formats, so the filtered slice may still be noisy on those engines. The raw tail -200 fallback immediately below it preserves full diagnostic information regardless. This is a minor, non-blocking gap.
• head -c 500 UTF-8 truncation is acceptable: For diagnostic shell output, truncating mid-sequence is an acceptable trade-off.
• CHANGELOG entry is cosmetically long: The sentence runs ~250 characters and is missing a trailing period. Not a blocker.
• No .ai/wheels/ documentation updates needed: Confirmed — this is a pure CI workflow change.
• Commit message is valid: ci(compat-matrix): make CF engine readiness diagnostics actionable on timeout passes commitlint: valid type, optional scope, subject under 100 chars, not ALL-CAPS.

Defended points

None. B raised no false positives to defend against, because I had no findings in my original submission.

Two observations from my own diff read not in B's analysis, added for completeness:

• The switch from grep -q "200\|404\|302" to grep -qE "^(200|302|404)$" is a genuine improvement — the anchored ERE pattern prevents false matches on HTTP codes that contain those substrings (e.g. "5200"). Minor correctness win.
• The env: CFENGINE: ${{ matrix.cfengine }} pattern is the correct GitHub-recommended defence against script injection — moving the matrix variable into an env var before shell interpolation. Worth noting as a security positive, not just a style change.

Updated verdict

Approve. This is a clean CI diagnostic improvement: no framework code is changed, the shell logic is correct, the security hardening of the env: injection pattern is appropriate, and the improved timeout output (HTTP code tracking, partial-progress logging, response-body sample, filtered-then-raw log dump) directly addresses the diagnosis gap that motivated the PR. The Lucee-specific stack filter and the long CHANGELOG sentence are minor cosmetic items, neither of which warrants blocking the merge.
