An in-memory provider.Provider whose state (Provisioning -> Running ->
Terminated -> purged) is a pure function of an injectable clock, not
background timers, so it's deterministic under tests and correct under
real time with no goroutine lifecycle to leak.
Once an instance is observed Running, it lazily acquires a real HTTP
CONNECT proxy listener so the health engine's through-the-proxy probe
(later steps) genuinely tunnels a request end to end, instead of the
healthcheck being simulated or bypassed for local development.
Redesigned the listener sharing model from what the plan assumed: the
plan's "one loopback IP per instance" doesn't work on macOS (only
127.0.0.1 binds without a privileged ifconfig alias, unlike Linux where
the whole 127.0.0.0/8 routes to loopback by default), and there's no
channel for a provider to report a port back to the reconciler anyway
(EffectivePort() is spec-only). Instances now share one real listener
per port, reference-counted at the package level rather than per
Provider instance, since a bound TCP port is a genuinely process-global
OS resource -- two separately configured mock-typed provider entries
must not both try to bind the same default port.
Fault injection wired both ways: MockConfig.FailNextCreates/FailWith for
demos, InjectCreateFailures(n, class) for tests. Create is idempotent by
name.
Caught and fixed a real test flake (not a logic bug): the freePort test
helper asked the OS for a free port via bind-then-close, a TOCTOU race
under t.Parallel() that let two tests collide on the same "free" port.
Replaced it with a monotonic counter, since these tests only need
uniqueness within the test run.
internal/provider/mock at 91.1% coverage, including an end-to-end test
that opens real sockets: Create -> Get past provisionDelay -> a real
http.Client tunnelling a CONNECT through the mock to a real TLS origin.
make test green across the whole repo.

Full ProxySpec/ProxyStatus/Proxy types per the plan: PlacementSpec,
CloudInitSpec, EndpointSpec, HealthCheckSpec, SecretKeySelector, all
defaults, and 7 CEL XValidation rules enforcing mode/provider
immutability, provider/endpoint required-iff-Managed/External, and
cloud-init exactly-one-of inline/secretRef.
Applies the four corrections identified during planning that would
otherwise be silent bugs: MaxLeases as *int32 (so an explicit 0 survives
Go round-trips instead of re-defaulting to 5), HealthCheck's
default={} marker (so nested defaults apply even when the field is
omitted entirely), MinLength=1 on Provider/CloudInit.Inline (so the CEL
has() checks stay simple), and listType=map on Conditions.
Adds pure helpers (EffectivePort, EffectiveHost, HealthCheckOrDefault,
MaxLeasesOrDefault) with table-driven tests, for use by the health
engine, discovery API, and spec-hash computation in later steps.
Patches the scaffolded placeholder controller test's resource literal to
a schema-valid spec so it survives the new CRD validation — the test
itself is rewritten wholesale in Step 4 alongside the real reconciler.
Regenerated deepcopy and the CRD; make test green (envtest confirmed all
7 CEL rules enforced by a real apiserver).

The plan for this build was written to docs/plans/ only after Step 0's
implementation had already started, instead of as its own first action
right after ExitPlanMode. CLAUDE.md said *where* to save plans but not
*when* relative to other work, so that ordering wasn't actually enforced.
Makes it explicit: copying the plan into docs/plans/ and committing it is
its own checkpoint that blocks starting Step 0.
Also adds a docs/plans-executions/ convention: one running, chronological
summary file per plan, appended to after each completed step, for a
human-readable narrative of how the plan actually went (judgment calls,
spec gaps, surprises) without duplicating the plan or the diff.
Backfills the Step 0 entry for the proxy-operator plan retroactively.

Bootstraps the empty repo into a kubebuilder go/v4 project: group
crawl.example.com, version v1alpha1, kind Proxy (namespaced). Keeps the
existing module path and preserves the repo's Go/testing/changelog
conventions from CLAUDE.md untouched.
Drops the scaffolded GitHub Actions workflows since the remote is Gitea,
not GitHub. Everything else is default kubebuilder output, unmodified,
so later diffs stay reviewable against a known baseline.
