 **Summary:** Introduced the `agent.Agent` interface to decouple the orchestrator from `copilotcli.Client`.

Introduced a layered config resolver (`internal/config/manager.go`) with `DefaultsSource`, `EnvVarSource`, and `FlagsSource`; `Config.PageRefresh` promoted to `*bool` to enable explicit-false override. Removed `json.go` and the `--config` flag; credentials are now supplied exclusively via flags or `BAUER_*` env vars. `BAUER_GITHUB_TOKEN` is now checked first in `GetGitHubToken`.

Switched from global `flag` package to `flag.FlagSet` for testability. Added mutual-exclusion check for `--open-pr` / `--open-issue` before any network calls. `--dry-run` semantics clarified in help text: standalone mode skips Copilot entirely; `--open-pr` mode applies changes locally but skips PR creation. Added `runOpenIssue` / `runOpenPR` stubs returning "not yet implemented". Added `BranchPrefix`, `OpenPR`, `OpenIssue` to `CLIFlags` struct and `FlagsSource.Load()`; added `CredentialsPath: "credentials.json"` fallback to `DefaultsSource`. Updated `Taskfile.yml` with split `build`/`build-api` tasks, standalone `run` using `{{.CLI_ARGS}}`, `run-api`, `test`, `lint`, and enhanced `verify-figma` with `FILE_KEY` check.

 **Summary:** Implemented `--open-issue` and `--open-pr` CLI modes. Added `--github-repo` flag (maps to `cfg.GitHubRepo`). Replaced the mutual-exclusion inline check with a pure `validateFlags(openPR, openIssue bool) error` function called immediately after `fs.Parse`, before any I/O or env-var resolution (T2.3). Implemented `runOpenIssue`: runs the orchestrator in dry-run mode to extract suggestions without invoking Copilot, then builds a structured markdown issue body (categorising suggestions as copy changes vs content additions, with optional Figma link and a next-steps command) and creates the issue via the GitHub REST API using `net/http` (T2.1). Implemented `runOpenPR`: resolves the GitHub token, runs the orchestrator with Copilot enabled, creates a new git branch `<prefix>/<runID>`, stages and commits all changes, pushes the branch, and opens a PR via the `gh` CLI (T2.2). Added `RunID string` field to `OrchestrationResult` so branch naming uses the artifact run ID. Added `GitHubRepo` to `CLIFlags` and `FlagsSource`. Created `internal/github/issue.go` (REST API `CreateIssue`) and `internal/github/git.go` (`RunGit` helper). Updated tests to use `validateFlags` and verify the workflow functions are implemented beyond stub status.

Resolved Figma comments are excluded from `ResolvedChunk.Comments`; screenshots are matched by node ID. Updated `internal/prompt/engine.go`: added `FigmaContextJSON` and `FigmaURL` fields to `PromptData`; added `GenerateChunksFromResolved` that batches `[]mapping.ResolvedChunk` into `[]PromptData` and serializes figma context as JSON; updated `RenderChunk` to parse `FigmaContextJSON` and render the figma-context template with `text/template` when non-empty. Created `internal/prompt/templates/figma-context.md` with anchor, screenshot, and comment sections. Extended `internal/artifacts/manager.go` with `WriteFigmaExtraction`, `WriteMappings`, and `WriteFigmaComments` methods that persist design data to `extraction/` alongside the existing gdocs extraction.

 **Summary:** Threaded Figma through the CLI and orchestrator (T2F.8) and added an optional MCP guidance block to prompts (T2F.9). Added `--figma-url` flag to `cmd/bauer/main.go`, wired into `CLIFlags.FigmaURL`. `orchestrator.Execute` now forks on `cfg.FigmaURL != ""`: the figma-aware path calls the new `generateChunksWithFigma()` method which fetches design data via `sources.FetchFigma`, runs `mapping.Resolver.Build`, persists figma artifacts (extraction, comments, mappings), and generates prompts via `engine.RenderChunksFromResolved`. For T2F.9: added `FigmaURL string` field (with `json:"-"`) to `figmaChunkContext` in `engine.go`; `RenderChunk` now sets `ctx.FigmaURL = data.FigmaURL` before template execution; added an optional MCP guidance block to `internal/prompt/templates/figma-context.md` that renders only when `{{if .FigmaURL}}`; added `Engine.RenderChunksFromResolved()` which generates figma-aware prompt files using `GenerateChunksFromResolved` + `RenderChunk`. `BAUER_FIGMA_TOKEN` env var usage mentioned in `--help` output.

 **Summary:** Implemented drift detection and mapping cache reuse for Figma-backed runs. `RunMetadata` and `RunIndexEntry` gained a `FigmaVersion` field, and three new methods were added to `artifacts.Manager`: `LoadPreviousMeta` (scans `runs.jsonl` in reverse to find the most recent successful run with a matching DocID and Figma file key), `LoadMappings` (reads `extraction/mappings.json` from a prior run), and `UpdateRunFigmaVersion` (patches the current run's `metadata.json` after a fresh Figma fetch). In `generateChunksWithFigma`, a `GetMeta` call is now made before any other Figma API calls; if the version is unchanged versus the previous run, the stored mappings are reused and `GetNodes`/screenshot downloads are skipped; if changed, a warning is logged and a full re-fetch proceeds. `Resolver.Build` was hardened with a post-process normalization step that explicitly marks any chunk with `Confidence < 0.5`, `Method == "fallback"`, or `Method == "none"` as `Status: "unresolved"`, preventing silent promotion of low-quality mappings.

 **Summary:** Added Docker support, env-file loading, secrets removal from the API request body, route rename, and a build task. T3.0 introduced a multi-stage `Dockerfile` (golang:1.22 builder + debian:bookworm-slim runtime with git, curl, and the GitHub CLI installed) and a `.dockerignore` that excludes secrets, build artifacts, and the git directory; two new Taskfile tasks (`docker-build`, `docker-run`) wire the image build and local container run. T3.1 installed `github.com/joho/godotenv` and updated `cmd/app/main.go` to call `godotenv.Load` for both `.env` and `.env.local` (errors silently ignored) before calling `run()`; `.env` was replaced with a committed, non-sensitive defaults file covering port, model, chunk size, page-refresh, output directory, and branch prefix. T3.2 stripped `Credentials`, `GitHubToken`, `OutputDir`, and `LocalRepoPath` from `APIRequest`, replacing them with env-var lookups (`BAUER_CREDENTIALS_PATH`/`GOOGLE_APPLICATION_CREDENTIALS` and `github.GetGitHubToken()`) inside the handler; `firstNonEmpty` and `firstNonZero` helpers apply request-field-overrides-env semantics; `SummaryModel` was added to `APIRequest` for future use. T3.3 renamed the `/api/v1/workflow` route to `POST /api/v1/workflows` using Go 1.22 method+path routing. T3.4 was already present in the Taskfile from a prior branch (`build-api` task).

 **Summary:** T5.1 added GitHub App authentication as the first fallback in `GetGitHubToken()`: when `GITHUB_APP_ID` is set, a short-lived RS256 JWT is signed with the App's RSA private key and exchanged for an installation access token via the GitHub REST API; PAT env vars and `gh auth token` remain as lower-priority fallbacks. T5.2 introduced `internal/auth/middleware.go` with `JWTMiddleware`, which validates Bearer tokens against a JWKS fetched from the OIDC issuer's discovery document; the middleware is bypassed silently (logged at Info) when `BAUER_OIDC_ISSUER` is unset, making it safe for local development. In `cmd/app/main.go`, the health and readiness endpoints remain on the public mux while `POST /api/v1/workflows`, `POST /api/v1/issues`, and `POST /api/v1/webhooks/jira` are now wrapped with `auth.JWTMiddleware` on a separate protected sub-mux.

+**Summary:** T4F.1 wires Figma into both API endpoints: `IssueRequest` already carried `figma_url` and `IssuesHandler` already set `cfg.FigmaURL`/`cfg.FigmaToken`, so the focus was adding `FigmaURL` to `workflow.APIRequest` and `WorkflowInput`, piping it through `ExecuteWorkflowHandler` and `ExecuteWorkflow` into `bauerCfg`, so `POST /api/v1/workflows` now also accepts optional `figma_url`. T4F.2 introduces the `ScreenshotHost` interface (`internal/artifacts/hosting.go`) with three implementations — `LocalFileServer`, `NopHost`, and an `S3Host` stub — and a `HostFromEnv` factory that selects the backend from `BAUER_STATIC_BASE_URL` / `BAUER_S3_BUCKET`. `IssuesHandler` now calls `formatIssueBodyWithHosting` and logs a warning when no hosting backend is configured but a `figma_url` was supplied. `cmd/app/main.go` conditionally mounts a `/static/` file-server route when `BAUER_STATIC_BASE_URL` is set, and `.env.example` documents the three new env vars.

+
+### Trade-offs
+
+1. **Fixes on tip vs per-branch**: All fixes applied to the tip branch (`feat/figma-phase-f-api`) rather than the branch that introduced each issue. Rationale: modifying middle branches would require rebasing all subsequent branches (6 branches), which is high-risk for automated tooling. The user can cherry-pick fixes into individual branches during PR review if needed.
+2. **`formatIssueBodyWithHosting` left as stub**: Full screenshot URL rewriting requires iterating over `OrchestrationResult` to find screenshot paths and calling `host.Host()` on each. This is non-trivial and should be a tracked follow-up, not a quick fixup.
+3. **Test coverage gaps**: Several new functions lack dedicated unit tests. The code compiles cleanly and all existing tests pass (`go test ./...`), confirming no regressions. Adding tests is recommended but not blocking for review.
