# Changelog

Append-only running history of all changes (AGENT.md §9.1). Newest last.

## 2026-09-19 — Project scaffold
- **What:** Initial runnable skeleton for the GitManager multi-repo dashboard.
  Added the Go backend (`cmd/server/main.go` + `internal/{config,logging,git,repos,render}`),
  the Echo HTTP server with `/`, `/help`, `/healthz`, and `/api/repos`, a
  read-only repo scanner that discovers repositories under `GIT_REPO_ROOTS` and
  keeps an in-memory index, the `<repo-list>` web component, shared design tokens
  (`web/static/app.css`), page shells (`web/templates/{index,help}.html`), and the
  dev tooling: `Dockerfile` (build/dev/runtime stages), `docker-compose.yml`,
  `.air.toml`, `.env.example`, `.gitignore`, `go.mod`.
- **Why:** Stand up the architecture defined in AGENT.md so feature work can begin.
- **Affects:** whole repo (foundation); `components/repo-list`.

## 2026-09-19 — Repo detail panel
- **What:** Added the `<repo-detail>` component (right dock) that listens for
  `repo:select` and shows a repo's remotes, local branches (current + upstream),
  and 20 most recent commits. Backed by a new `GET /api/repo?path=` endpoint
  (restricted to indexed repos) and new read-only git readers
  (`LocalBranches`, `RecentCommits`, `RemoteDetails`) plus `repos.BuildDetail`
  and `Index.Get`. `<repo-list>` now highlights the selected repo; `index.html`
  lays the two panels out left/right; help page documents the detail view.
- **Why:** Make the dashboard drill into a single repository (the detail half of
  the list+detail default in AGENT.md §4).
- **Affects:** `components/repo-detail`, `components/repo-list`,
  `internal/git`, `internal/repos`, `cmd/server`, `web/templates`.

### Notes to confirm (from AGENT.md §11)
- **Go module path** is the placeholder `gitmanager`; change it if this gets a
  canonical import path (e.g. a GitHub URL).
- All items in AGENT.md §11 (discovery strategy, background fetch, forge
  providers, listen address, container credentials) remain open.

## 2026-09-19 — Redefine the app as a two-way Claude companion (contract only)
- **What:** Updated AGENT.md to make the Claude integration the defining pillar,
  no code yet. §0 now states the two-way purpose (Claude↔app) and the
  non-expert, GUI-first goal; added law §1.7 (one service layer behind both the
  GUI and the MCP server); stack table gained MCP server (Go SDK over Streamable
  HTTP at `/mcp`), SSE (app→browser), and flipped forge to Gitea-first read+write;
  layout added `internal/{service,mcp,activity}`; §6 added the right-click
  plain-language command vocabulary; **§8 rewritten** into "Claude integration"
  (8.1 MCP server, 8.2 activity feed + active project, 8.3 graceful project
  handoff, 8.4 forge read+write with "Merge & clean up"); §10 step 4 and §11
  updated (three decisions resolved, new open items). `.env.example` now documents
  `GITEA_TOKEN` (read+write scope).
- **Why:** Thomas described the real vision — the app should act as an extension
  of Claude: usable like an MCP by Claude, notifying Claude of in-app actions to
  stay in sync, cooperative project handoff when he's interrupted, plain-language
  right-click commands for non-experts, and one-click "merge & clean up" so PRs
  stop cluttering repos. Decisions locked: cooperative pull-first handoff; Gitea
  writes enabled (confirmed per §1.4); MCP over HTTP `/mcp`.
- **Affects:** `AGENT.md`, `.env.example` (architecture/contract only — no code).

## 2026-09-19 — Service layer + MCP server (Claude integration, read tools)
- **What:** Slice 1 — extracted `internal/service`, the one capability layer both
  the HTTP API and the MCP server call (§1.7); the `/api/repos` and `/api/repo`
  handlers now route through it. Slice 2 — added `internal/mcp`: an MCP server
  (`github.com/modelcontextprotocol/go-sdk` v1.8.0) served over Streamable HTTP at
  `/mcp`, with read tools `list_repos` and `get_repo` as thin adapters over the
  service. Added a round-trip test (`internal/mcp/mcp_test.go`) using a real temp
  git repo + the in-memory MCP transport. Verified the HTTP `/mcp` handshake
  locally and in Docker.
- **Why:** First step of the two-way Claude integration (AGENT.md §8.1) — prove
  Claude can connect to the app over MCP before building deeper features on it.
- **Affects:** `internal/service` (new), `internal/mcp` (new), `cmd/server/main.go`,
  `go.mod`/`go.sum`, `.air.toml`.
- **Gotcha:** Docker-on-Windows bind mounts do NOT deliver filesystem events, so
  air's watch-based reload silently never fired. Fixed by enabling air polling
  (`poll = true`, `poll_interval = 500` in `.air.toml`).

## 2026-09-20 — HTTPS for the MCP connector (local TLS via mkcert)
- **What:** Added an optional HTTPS listener alongside HTTP. New config
  `HTTPS_ADDR`, `TLS_CERT_FILE`, `TLS_KEY_FILE`; when set, `cmd/server` starts
  `e.StartTLS` on the same Echo app (best-effort — a missing cert logs a warning
  and stays HTTP-only). docker-compose publishes `127.0.0.1:8443` and points the
  TLS vars at `certs/localhost.pem` (mounted via the existing source mount).
  `.gitignore` ignores `/certs/`; `.env.example` documents the mkcert steps.
- **Why:** Claude Desktop's custom MCP connector only accepts `https://` URLs.
  Local TLS with an mkcert-trusted cert lets `https://localhost:8443/mcp` work
  without exposing the unauthenticated app via a public tunnel (AGENT.md §8.1).
- **Affects:** `internal/config`, `cmd/server/main.go`, `docker-compose.yml`,
  `.gitignore`, `.env.example`, `AGENT.md` (§8.1, §11).
- **Host setup (user-run):** the local CA install (`mkcert -install`) is a
  security-settings change performed by the user, not the app.

## 2026-09-20 — Connect Claude Desktop via local stdio bridge (mcp-remote)
- **What:** Corrected the Claude Desktop connection method in AGENT.md (§8.1, §11).
  The GUI "Add custom connector" flow can NOT reach a localhost server — it probes
  and calls tools from Anthropic's cloud, so `https://127.0.0.1:8443/mcp` fails
  "couldn't reach the server" even though a local browser reaches it. The working
  path is a local stdio bridge in `claude_desktop_config.json`:
  `mcpServers.gitmanager = cmd /c npx -y mcp-remote http://127.0.0.1:8080/mcp`.
  Added that entry to the user's Claude Desktop config (backup saved alongside).
- **Why:** Keep the app localhost-only + unauthenticated (§0) while still letting
  Claude Desktop drive it. `mcp-remote` runs locally, so it reaches the local
  endpoint directly — no public exposure, no HTTPS needed for this path.
- **Affects:** `AGENT.md` (§8.1, §11); user's `claude_desktop_config.json` (outside
  the repo). HTTPS/`:8443` from the prior entry stays available but is now optional.

## 2026-09-20 — Slice 3: activity feed + active project (§8.2)
- **What:** Added `internal/activity` (thread-safe active project + bounded event
  feed with subscriber fan-out, mirrored to logs, no datastore). Service gained
  `ActiveProject`/`SetActiveProject`/`RecordActivity`/`Activity`/`SubscribeActivity`
  (and `service.New` now takes the feed). New MCP tools `get_active_project`,
  `set_active_project`, `get_activity` (object-wrapped outputs). New HTTP:
  `GET/POST /api/active-project`, `GET /api/activity`, and `GET /events` (SSE).
  New `<activity-feed>` component (live via EventSource); `<repo-list>` now sets
  the active project on selection (a user action). Extended the MCP test to cover
  the new tools; help page documents the feature.
- **Why:** The coordination foundation for the graceful project handoff (§8.3):
  the app and Claude share one active-project + activity view. User actions are
  recorded as `actor:user`, Claude's as `actor:claude`, so each side can see what
  the other did.
- **Affects:** `internal/activity` (new), `internal/service`, `internal/mcp`
  (+test), `cmd/server/main.go`, `components/activity-feed` (new),
  `components/repo-list`, `web/templates/{index,help}.html`.

## 2026-09-20 — Slice 4: graceful project handoff (§8.3)
- **What:** `internal/activity` gained a pending-switch model
  (`RequestSwitch`/`PendingSwitch`/`AckSwitch`/`CancelSwitch`); `AckSwitch`
  atomically sets the active project to the requested target and records a
  `switch-completed` event with Claude's summary. Service methods added. New MCP
  tools `get_pending_switch` and `ack_switch` (request is user-only — no MCP tool
  raises it). HTTP: `GET/POST/DELETE /api/switch`. New `<handoff-bar>` component:
  "Ask Claude to switch to <active>", the "waiting for a good stopping point"
  state with Cancel, and the completion notice; `<activity-feed>` also updates the
  active project on `switch-completed`. Extended the MCP test to cover the full
  request→ack→clear flow. Help page + AGENT.md §8.3 updated.
- **Why:** The headline feature — the user asks Claude to switch projects; Claude
  finishes to a safe stopping point, then `ack_switch` completes it and the app
  notifies the user over SSE. The switch is Claude-completed at a checkpoint,
  never app-forced (§1.4-class rule).
- **Affects:** `internal/activity`, `internal/service`, `internal/mcp` (+test),
  `cmd/server/main.go`, `components/handoff-bar` (new), `components/activity-feed`,
  `web/templates/{index,help}.html`, `AGENT.md` (§8.3).
- **Verified live:** request → "waiting" → cancel, all over SSE with activity
  logging. The ack/completion path is covered by the test; its live ✅ notice
  needs the two new MCP tools, which appear after the next Claude Desktop restart.

## 2026-09-20 — Slice 5: Gitea forge — PRs + "Merge & clean up" (§8.4)
- **What:** New `internal/forge` — provider-abstracted forge boundary with a Gitea
  impl (`code.gitea.io/sdk/gitea`), a remote-URL parser (`ParseRemote`, tested),
  and read+write ops: `ListPullRequests` and `MergeAndCleanup` (squash-merge +
  delete the head branch, only when head/base share a repo). Service resolves a
  repo → owner/repo via its remotes (prefers origin) and records a `pr-merged`
  activity event. New config `GITEA_URL` + `GITEA_TOKEN` (forge is nil/disabled
  without both). New MCP tools `list_prs` and `merge_and_cleanup_pr` (the merge
  tool's description tells Claude to confirm first, §1.4). HTTP
  `GET /api/repo/prs`, `POST /api/repo/pr/merge`. New `<pr-list>` component with a
  confirming "Merge & clean up" button; hidden when no forge is configured.
- **Why:** The feature Thomas asked for — make PRs usable by merging and removing
  the branch in one tidy step, from the app or via Claude.
- **Affects:** `internal/forge` (new, +test), `internal/config`,
  `internal/service`, `internal/mcp`, `cmd/server/main.go`,
  `components/pr-list` (new), `web/templates/{index,help}.html`, `.env.example`,
  `go.mod`.
- **Not yet live-tested:** needs `GITEA_URL`+`GITEA_TOKEN` set and a real PR;
  build/vet/tests pass and the parser is unit-tested. A real merge is irreversible
  — will only run one against a PR Thomas designates, with confirmation.

## 2026-09-20 — Forge live-tested (Merge & clean up)
- **What:** With `GITEA_URL`+`GITEA_TOKEN` set, verified end-to-end against
  git.nilles.net: created an isolated throwaway PR via the Gitea API (on a
  dedicated base branch so `main` was untouched), listed it through `GET
  /api/repo/prs`, then ran `POST /api/repo/pr/merge` → `{merged:true,
  branchDeleted:true}`; confirmed the branch was gone (404), the PR list emptied,
  and the feed logged `pr-merged`. Cleaned up the base branch afterward.
- **Why:** Prove the write path with real auth before relying on it.
- **Affects:** none (runtime verification only; no code change).

## 2026-09-20 — Slice 6: right-click command menu + git write actions (§6)
- **What:** git boundary gained `Pull`/`Push`/`Commit`/`DiscardAll` (the last is
  §1.4-destructive). Scanner got `RefreshRepo` (single-repo re-scan). Service
  gained `GitFetch/GitPull/GitPush/GitCommit/GitDiscard` — each records a `git-*`
  activity event (ok/failed) and refreshes the repo after success; `service.New`
  takes a refresh hook. New HTTP `POST /api/repo/git {path, op, message?}`. New
  `<repo-menu>` overlay (plain-language commands: Get latest, Publish, Check for
  updates, Save my work…, Set as active project, Ask Claude to switch here, Copy
  path, and the confirmed Discard all changes…); `<repo-list>` emits
  `repo:contextmenu` on right-click. Added `internal/service` test covering
  commit/discard on a temp repo.
- **Why:** The GUI-first reason the app exists (§0) — run git in plain language
  without a terminal. Logic lives in the shared service (§1.7) so the same ops can
  be exposed to Claude via MCP next.
- **Affects:** `internal/git`, `internal/repos`, `internal/service` (+test),
  `cmd/server/main.go`, `components/repo-menu` (new), `components/repo-list`,
  `web/templates/{index,help}.html`.
- **Next:** expose these git ops as MCP tools so Claude can run them too.

## 2026-09-20 — Slice 7: git commands as MCP tools (§1.7 symmetry)
- **What:** Added MCP tools `git_fetch`, `git_pull`, `git_push`, `git_commit`,
  and `git_discard_changes` — thin adapters over the existing service methods
  (actor=claude), so Claude can run the same commands as the right-click menu.
  `git_discard_changes`'s description flags it destructive and tells Claude to
  confirm first (§1.4). Extended the MCP test with a `git_commit` round-trip.
  Synced AGENT.md §8.1's tool list to the actual names.
- **Why:** Complete the §1.7 symmetry — every capability reachable from both the
  GUI and Claude.
- **Affects:** `internal/mcp` (+test), `AGENT.md` (§8.1).
- **Note:** the new tools appear in Claude Desktop only after its next restart
  (tool list cached per connection); network ops still need container git creds.
