Replaces the shared GITEA_MCP_DEFAULT_TOKEN for all callers. When a
request's bearer validates directly against Gitea's own /api/v1/user,
that token is used for every upstream call this request makes instead
of the service PAT, and the caller identity comes from Gitea's own
login rather than the proxy header. Any other bearer (static token,
JWT, none) falls through unchanged to the existing chassis auth.
Prep: Authentik now SSOs into Gitea (infra a32801c), so each real user
can mint their own PAT from their own linked account.

Additive: gitea-mcp now validates JWTs from a LIST of issuers — the existing
Authentik issuer (DEX_ISSUER_URL) AND, when K8S_ISSUER_URL is set, the in-cluster
k8s OIDC issuer for audience-bound ServiceAccount tokens. Lets in-cluster pods
authenticate with kubelet-rotated projected SA tokens instead of a static bearer.
- config: K8S_ISSUER_URL + K8S_MCP_AUDIENCE.
- cmd/gitea-mcp/k8soidc.go: HTTP client that fetches the k8s OIDC discovery/JWKS
with the cluster CA + this pod's SA bearer (k3s requires an authed fetch;
anonymous is 401).
- main.go: build the issuer list; switch NewJWTValidator -> NewMultiJWTValidator.
The k8s issuer is best-effort — if its client can't be built (not in a pod) or
its discovery is unreachable at startup, it is DROPPED and we fall back so
Authentik/static auth is never taken down. Smoke-tested: off-pod it logs the
skip and starts static-only; static-bearer /mcp returns 400 (auth passed), not 401.
- bump mcp-chassis v0.3.0 -> v0.5.0 (multi-issuer + per-issuer HTTPClient).
Refs infra ADR-0011; enables retiring the in-cluster static bearer.

- Dockerfile: GOPRIVATE and the http→https insteadOf rewrite now name
git.d-ma.be (was the pre-rename gitea.d-ma.be; masked at build time only by
GOPROXY=direct + GOSUMDB=off).
- .context/PROJECT.md Repo URL → git.d-ma.be, adapters regenerated
(CLAUDE.md, AGENTS.md, .cursorrules, .aider.conventions.md, system-prompt.txt).
- main.go: version is now a `-ldflags -X main.version` overridable var defaulting
to "dev" instead of a hardcoded, drifting "0.1.0".

Bumps mcp-chassis to v0.3.0, which adds structured audit logging on every auth
rejection and returns 503 temporarily_unavailable (not a silent 401) when Dex is
unreachable at validation time. Wires slog.SetDefault so those audit lines flow
through gitea-mcp's JSON handler.
Together with the earlier /healthz jwt-status reporting and startup degradation
warning, this closes#6 (Dex-down is now observable and distinct from a bad
token) and #9 (auth failures are audit-logged: reason, IP, token type, hashed
fingerprint — never the raw token).

CallerMiddleware silently preferred X-Auth-Request-User over X-Forwarded-User
with no explanation and no signal when both were set. Documented the precedence
(X-Auth-Request-User is the verified OIDC identity oauth2-proxy sets, so it is
authoritative; X-Forwarded-User is a fallback), and it now takes a *slog.Logger
and warns when both headers are present and disagree, so a proxy
misconfiguration is visible instead of silently resolved. Table-driven tests
cover precedence (both/single/none) and the conflict-warning path.

Gitea host renamed (infra ADR-0004); the mcp-chassis dep already migrated
(3329ff3), so the sequencing gate is clear. `go mod edit -module` + bulk import
rewrite across all .go files. gitea-mcp is a server binary (not an imported
library), so no downstream consumers break. build + task check green.

The image build's `go mod download` failed on the stale
gitea.d-ma.be/mathias/mcp-chassis import (the gitea→git rename; the server no
longer serves a matching go-import meta tag). This is the latent #74 breakage
flagged for gitea-mcp, triggered by the first clean rebuild since the rename
(the #42 push). Point at git.d-ma.be/mathias/mcp-chassis v0.2.0 + go mod tidy.
Unblocks deploying the #42 create_project_from_template fix. gitea-mcp's own
module path stays gitea.d-ma.be (main module, not fetched — separate cleanup).
Refs #74, #42.

main.go and tests now share one registration list so a tool wired in one
place cannot silently go missing from the other. Adds a dispatch round-trip
test asserting every registered tool resolves and ships a parseable schema.

Adds issue_edit, mapping to Gitea's PATCH /repos/{owner}/{repo}/issues/{index},
so an existing issue's title and/or body can be edited through the MCP surface.
Previously the only post-create mutation was issue_comment, which buries
backlinks in the thread instead of the canonical body.
Partial patch via pointer fields (omitempty): omitted fields are left
untouched, an explicit empty string clears a field. Body is sent verbatim —
no identity footer — so repeated edits are idempotent, matching the acceptance
criteria. Registered alongside the other issue tools for tool_search discovery.
Closes#34
/healthz now returns JSON with three-state JWT status: disabled
(DEX_ISSUER_URL unset), enabled (validator initialized), or
degraded (configured but init failed — only static-token auth
currently accepted). last_error surfaces the init failure so ops
can correlate with Dex outage windows.
Partial fix for #6. The cited internal/auth/jwt.go moved out
of this repo in 658f4ba (mcp-chassis migration); per-attempt
logging and 503 + WWW-Authenticate temporarily_unavailable
require chassis-side changes and a coordinated v0.1.1 bump
across all MCP consumers — tracked separately.

First real port of the MCP chassis library — abort-criterion check for
spike S3 of the 2026-05 homelab architecture review.
Changes:
- Drop internal/auth/jwt.go (~79 LOC) — chassis provides JWTValidator
with identical signature.
- Drop internal/auth/bearer.go (~42 LOC) — chassis BearerMiddleware
has the same static-or-JWT semantics plus an optional WWW-Authenticate
resource_metadata challenge (consumed via new resourceMetadataURL arg).
- Drop internal/auth/bearer_test.go — same scenarios are covered in
the chassis bearer_test.go now.
- main.go: import chassis as `chassisauth`, build resourceMetadataURL
only when both DexIssuerURL + MCPResourceURL are set, replace the
inline /.well-known/oauth-protected-resource handler with the chassis
ProtectedResourceHandler.
internal/auth/caller.go (oauth2-proxy header → context) stays — chassis
out-of-scope.
Net LOC change: -~150 LOC duplicated infra + a 5-LOC import.
go.mod gains gitea.d-ma.be/mathias/mcp-chassis v0.1.0 (jwx/v2 + testify
already transitive, no new top-level deps).
Verifies abort criterion: one PR, one binary's worth of port, task check
green (lint + test + vet + govulncheck clean). Per the S3 spike spec,
this clears the chassis to continue. Next port: hyperguild/ingestion
(brain-mcp), filed as a follow-up.

Adds the *_list partners that the existing *_get tools have been
missing. Same pattern as repo_list — owner allowlisted, capLimit
helper for pagination, next_page surfaced when the page is full.
internal/gitea/issues.go:
- ListIssues(owner, repo, args) hitting
GET /api/v1/repos/{owner}/{repo}/issues with type=issues server-side
so PRs don't leak in (gitea conflates them on this endpoint).
- ListIssuesArgs struct: State, Labels, Since (ISO 8601), Page, Limit.
internal/gitea/workflows.go:
- ListWorkflowRuns(owner, repo, args) hitting
GET /api/v1/repos/{owner}/{repo}/actions/runs.
- Expanded WorkflowRun struct with DisplayTitle, Event, HeadSHA,
HeadBranch, WorkflowID, RunNumber, UpdatedAt, Actor so callers
can pin runs to a commit / branch without a second lookup.
- ListWorkflowRunsArgs: Branch, HeadSHA, Status, Event, Workflow,
Page, Limit. Status/Event 'all' treated as no-filter.
internal/tools/issue_list.go:
- Default state=open, default limit=30 (matches repo_list).
- next_page returned only when len(issues) == limit.
internal/tools/workflow_run_list.go:
- Default limit=10 (most common use is 'what just happened',
not paging).
- Returns runs + total + optional next_page.
Tests: table-driven for both — happy path, empty result, filter
combinations, allowlist rejection. workflow_run_list also asserts
the 'status=all is no-op' behavior (no query param emitted).
Closes#28Closes#29
Adds two MCP tools that PATCH /api/v1/repos/{owner}/{name}/issues/{number}
with {"state":"closed"} or {"state":"open"}. Both use a shared
SetIssueState helper on the gitea client.
- internal/gitea/issues.go: SetIssueState method using the existing
PatchJSON + MapStatus + json.Unmarshal pattern from GetIssue.
- internal/tools/issue_close.go: IssueClose tool. owner+name+number
args. Owner allowlist enforced. Returns the updated issue. Reversible
via issue_reopen, classified LOW risk.
- internal/tools/issue_reopen.go: mirror of IssueClose with
state="open". Same risk profile.
- Registered both tools in cmd/gitea-mcp/main.go.
- Tests for both: success (asserts PATCH method, path, body), 404,
and allowlist rejection — same shape as issue_get_test.go.
Closes#30
issue_get: GET /repos/{owner}/{repo}/issues/{number} — full issue with labels, assignees, comment count
release_create: POST /repos/{owner}/{repo}/releases — create release and tag in one call
repo_delete: DELETE /repos/{owner}/{repo} — confirm=<repo name> required, blocks accidents
repo_tree: GET /git/trees/{ref}?recursive=1 — full recursive file tree
repo_topics_update: PUT /repos/{owner}/{repo}/topics — replace topic list
file_read: detect array response and return descriptive error for dir paths
repo_create: POST /user/repos or /orgs/{org}/repos, is_org flag routes
repo_update: PATCH /repos/{owner}/{repo}, confirm required when private=false
repo_mirror_push: add/list/delete push mirrors, password never returned
Previously BearerMiddleware allowed requests with no Authorization
header to pass through whenever GITEA_MCP_DEFAULT_TOKEN was set. The
intent was "fall back to the service PAT for upstream Gitea calls,"
but the side effect was that anyone could hit /mcp anonymously and the
server would happily proxy requests as the service account.
Drop that path. Auth on /mcp now requires either:
- a valid Dex-issued JWT, or
- a Bearer matching GITEA_MCP_STATIC_TOKEN.
The Gitea service PAT (GITEA_MCP_DEFAULT_TOKEN) is no longer wired
into BearerMiddleware at all — it stays an upstream-client concern,
used by gitea.NewClient for outbound API calls only. This decouples
"can this caller invoke a tool" from "what credentials does the tool
use against Gitea".
Tests updated: drop the NoAuthHeader_WithDefault permissive case, add
NoAuthHeader_RejectsEvenWhenStaticConfigured to lock in the new
behavior.
Closes part of mathias/infra#2.

claude.ai connectors call the server with no Authorization header (confirmed
via request logging). Add a configurable default Gitea PAT so unauthenticated
clients (like claude.ai) can still reach the server.
Claude Code continues to pass per-request PATs; defaultToken="" preserves
the existing strict behaviour when the env var is unset.

Callers now supply their own Gitea PAT as a Bearer token; the server validates
it against GET /api/v1/user and threads it through context to all downstream
Gitea API calls. GITEA_API_TOKEN env var and the GiteaAPIToken config field are
removed.
Wires branch_list, branch_delete, branch_protection_get, pr_list,
pr_merge, dir_list, file_delete, tag_create, and repo_status into the
