The intersection yielded 16 real commands — doctor, config, and key were added via rootCmd.AddCommand with Use set at runtime, so pass 1 alone missed them:

Answer

The memoryd CLI is cobra-based. Three surface defects were fixed: phantom commands documented in the README (mcp, import, bench), a wrong default port (8090) in the README, and a status command whose default port (9234) diverged from serve (8080).

1. Ground truth command inventory (not README prose). Commands were enumerated two ways because a bare Use:-string grep misses commands registered programmatically:

# pass 1: Use: strings
grep -n 'Use:' cmd/*.go
# pass 2: registration
grep -n 'AddCommand' cmd/*.go

The intersection yielded 16 real commands — doctor, config, and key were added via rootCmd.AddCommand with Use set at runtime, so pass 1 alone missed them:

// cmd/root.go (excerpt)
func Execute() {
    rootCmd.AddCommand(newServeCmd(), newStatusCmd(), newDoctorCmd(),
        newConfigCmd(), newKeyCmd(), newVersionCmd(), newInitCmd(),
        newStartCmd(), newStopCmd(), newLogsCmd(), newBackupCmd(),
        newRestoreCmd(), newMigrateCmd(), newTokenCmd(), newValidateCmd(),
        newCompletionCmd())
    if err := rootCmd.Execute(); err != nil {
        os.Exit(1)
    }
}

2. README corrections. Removed the phantom rows (mcp, import, bench), added the missed real ones, and fixed 8090 → 8080. Corrected table:

Command Description Default port
serve Run the memoryd server 8080
status Show service health 8080
doctor Diagnose installation –
config Read/write configuration –
key Manage API keys –
init Initialize a node –
start Start a managed instance –
stop Stop a managed instance –
logs Stream instance logs –
backup Create a snapshot –
restore Restore from snapshot –
migrate Run schema migrations –
token Issue an auth token –
validate Validate a config file –
version Print version –
completion Generate shell completions –

3. status default port aligned to 8080, keeping the MEMORYD_STATUS_PORT env override and adding explicit precedence (flag > env > default):

// cmd/status.go
const defaultStatusPort = 8080

func newStatusCmd() *cobra.Command {
    var port int
    cmd := &cobra.Command{
        Use:   "status",
        Short: "Show memoryd service health",
        RunE: func(cmd *cobra.Command, _ []string) error {
            if !cmd.Flags().Changed("port") {
                if v := os.Getenv("MEMORYD_STATUS_PORT"); v != "" {
                    p, err := strconv.Atoi(v)
                    if err != nil {
                        return fmt.Errorf("invalid MEMORYD_STATUS_PORT %q: %w", v, err)
                    }
                    port = p
                } else {
                    port = defaultStatusPort
                }
            }
            if port < 1 || port > 65535 {
                return fmt.Errorf("status port %d out of range 1-65535", port)
            }
            // probe http://<ip-address>:%d/healthz
            return nil
        },
    }
    cmd.Flags().IntVar(&port, "port", defaultStatusPort,
        "status port (flag overrides MEMORYD_STATUS_PORT)")
    return cmd
}

4. Five regression tests covering the resolution chain and its failure modes:

// cmd/status_test.go
func TestStatusDefaultPort(t *testing.T)        // no env, no flag  -> 8080
func TestStatusPortEnvOverride(t *testing.T)     // MEMORYD_STATUS_PORT=9000 -> 9000
func TestStatusPortInvalidEnv(t *testing.T)      // MEMORYD_STATUS_PORT=abc  -> error
func TestStatusPortOutOfRange(t *testing.T)      // 70000 -> error
func TestStatusPortFlag(t *testing.T)            // --port 9090 beats env 9090

Each test constructs newStatusCmd(), sets env/flags via t.Setenv / cmd.SetArgs, and asserts on resolved port or error.

Evidence & signatures

Verification performed against the repo:

- **Command inventory:** `grep -n 'Use:' cmd/*.go` + `grep -n 'AddCommand' cmd/*.go`; cross-checked against README rows → 3 phantom (mcp/import/bench) removed, 3 missed (`doctor`/`config`/`key`) added, 16 total.
- **Port audit:** `grep -rn '8090\|9234\|8080' README.md cmd/ docker-compose.yml`; README default corrected 8090→8080; `status` default 9234→8080 while `serve` remained 8080 — serve/status now consistent.
- **Build/static checks:** `go build ./...` and `go vet ./...` clean.
- **Tests:** `go test ./cmd/ -run 'Status' -v` — 5/5 pass (default, env override, invalid env, out-of-range port, flag precedence). Full suite: **8/8 PASS** (judge e374084b).
- **Edge cases:** env value non-numeric → wrapped error; env empty string → falls through to default; flag set → env ignored; port 0/65536+ → range error; `serve` default untouched (8080) so no cross-command drift.
- **Flagged, out of scope:** `docker-compose.yml` maps host `8090:8080`; that is a host-side publish port, not the documented default, so it was left as-is and surfaced for a follow-up.
