Subject: [PATCH 01/10] feat(cigen): CIPlan model + Analyze typed derivations

Introduces cigen package with platform-neutral CIPlan struct and
Analyze() function that derives PluginInstall, PlanGuard, Migrations,
Build, Secrets, Smoke, Phases, and Triggers from typed WorkflowConfig
fields. Includes golden fixture + 4 passing tests.

Subject: [PATCH 02/10] feat(cigen): secrets-union + smoke derivation +
 Warnings (state-derived/case)

Extends Analyze() to union secrets.entries, ${VAR} refs from
env_vars_secret and iac.provider config fields, and migrations DBEnv
into a deduplicated SecretRef slice. Smoke derives URL+path from an
infra.container_service module's health_check + PRIMARY domain. Warnings
surface state-derived secrets (IaC output / migrations DBEnv) and
non-upper-case secret names. Multisite-shaped fixture + 4 tests.

Subject: [PATCH 03/10] feat(cigen): GitHub Actions renderer (structured,
 valid-yaml)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

RenderGitHubActions() emits a single workflow file with plan
(PR-only), apply (or apply-prereq→apply-deploy with needs for
multi-phase), optional migrations step in the last apply job,
smoke curl job, wfctl plugin install step, setup-wfctl version pin,
and per-secret ${{ secrets.NAME }} env entries. All output parses
as valid YAML. 6 tests.

Subject: [PATCH 04/10] feat(cigen): GitLab CI renderer

RenderGitLabCI() emits .gitlab-ci.yml with plan/apply/smoke stages,
merge-request rules, needs-chaining for multi-phase, secret refs as
$NAME CI variables, and plugin install in before_script. No deprecated
'only:' syntax. Output parses as valid YAML. 5 tests.

Subject: [PATCH 05/10] refactor(wfctl): replace CI templates with cigen-backed
 generate

Replaces the ghaInfraTemplate/ghaBuildTemplate/gitlabCITemplate text
templates and their generateGitHubActions/generateGitLabCI functions
with thin wrappers that build a minimal CIPlan from ciOptions and
delegate to cigen.RenderGitHubActions / cigen.RenderGitLabCI.
runCIGenerate now routes through cigen.Analyze + renderer with full
--write guard, --diff/--exit-code, --from-plan, and --phase-config
flags. Legacy ciOptions + generateCIFiles retained for backward compat.
Updated ci_test.go assertions to match cigen output.

Subject: [PATCH 06/10] feat(wfctl): wfctl ci plan +
 --from-plan/--diff/--exit-code

Adds 'wfctl ci plan' subcommand (ci_plan.go) that calls cigen.Analyze
and writes CIPlan JSON to --out (default stdout). Supports
--phase-config for 2-phase plans, --wfctl-version pin, --branch and
--runner overrides. Tests: runCIPlan writes parseable JSON with
warnings+phases; runCIGenerate --from-plan loads plan and renders
without re-analyzing; --diff exits 0 when files match; --write guard
rejects overwrite without flag.

Subject: [PATCH 07/10] feat(mcp): ci_plan tool + generate_github_actions via
 cigen

Adds new ci_plan MCP tool (handleCIPlan) that writes yaml_content to
a temp file, calls cigen.Analyze, and returns the CIPlan JSON.
Routes handleGenerateGithubActions through cigen.Analyze +
RenderGitHubActions; legacy cd_yaml path retained for backward compat
via mcpGenerateCDWorkflow; ci_yaml now contains cigen output.
mcpAnalyzeFromYAML helper handles temp-file lifecycle for MCP
yaml_content inputs. Updated 3 existing GHA tests + added 3 new
ci_plan tests.

From b9a264ab38b76cb09e46fcfaeeb947f8cd1e8002 Mon Sep 17 00:00:00 2001
From: Jon Langevin <codingsloth@pm.me>
Date: Sat, 30 May 2026 16:24:41 -0400
Subject: [PATCH 08/10] fix: runtime-launch fixes + lint zero

- resolveOutputPath: respect explicit --out dir for all paths including
  .github/workflows/ subdirectories (was only used for flat names)
- ci_plan: add -c shorthand for --config
- render_gha.go: replace b.WriteString(fmt.Sprintf()) with fmt.Fprintf
- render_gitlab.go: same + use %q for quoted YAML strings
- ci.go: remove unused detectModuleTypes + renderCITemplate; drop bytes/
  text/template/yaml.v3 imports
- mcp/wfctl_tools.go: remove unused mcpGenerateCIWorkflow
golangci-lint: 0 issues

Subject: [PATCH 09/10] fix(wfctl): ci --help exits 0

Add --help/-h/help cases to runCI switch so 'wfctl ci --help' returns
nil (exit 0) instead of the error from ciUsage().

Subject: [PATCH 10/10] fix(cigen): logical config path for MCP plans; real
 plan guard; relativize trigger paths; minors

CRITICAL: MCP ci_plan wrote yaml_content to an os.CreateTemp file and
returned a CIPlan whose DeployPhase.ConfigPath pointed at the deleted
/tmp path, so generated CI steps + paths: filter referenced dead paths.
Added Options.ConfigPathAlias; mcpAnalyzeFromYAML now passes a stable
logical name (deploy.yaml / deploy.prereq.yaml).

IMPORTANT: GHA PlanGuard was a no-op (`grep -q ... || true`). Replaced
with a real gate mirroring the multisite infra.yml pattern: visible
`wfctl infra plan | tee`, then `exit 1` when the plan includes
replace/destroy. No `|| true`.

IMPORTANT: writePhasePaths leaked absolute config paths into the GHA
paths: trigger filter (never matches a checkout). Analyze now
relativizes ConfigPath to cwd via filepath.Rel, falling back to
filepath.Base when it escapes cwd.

MINORS: removed redundant `|| m.Type == "iac.provider"`; dropped the
no-op GitLab `variables: {NAME: $NAME}` block (project CI vars are
auto-injected); added explicit parens to the apply if:; added
cigen/testdata/prereq.yaml fixture.

Tests: plan-guard-real-gate, no-plan-guard-when-unset, relative-paths
filter, absolute-path-relativized, alias-verbatim, MCP
config_path-is-logical-not-temp + two-phase logical paths, GitLab
no-redundant-secret-vars.
