Per the dispatch: this PR builds + gets driver-review + HOLDS on the 7d508035 gate (same as #2852); I will NOT route a 2nd-genuine reviewer until sign-off. This commit ships the CRITICAL selection scaffolding (the wire that the public-fetch activation #2900 + the cap fix #2845 plus this PR's removal-of-SM-as-config-transport all stack on): CHANGES ======= 1. workspace-server/internal/provisioner/template_assets.go - NEW: noopTemplateAssetFetcher type — self-host default. Load() returns (nil, nil) — "no assets to add" — so the call site in collectCPConfigFiles treats self-host as the "no external asset channel" case (cfg.TemplatePath + cfg.ConfigFiles handle /configs locally). - NEW: NoopTemplateAssetFetcher() constructor — exported so main.go can wire it via the selection helper. - NEW: FetcherSelection struct — the selection result (Fetcher, Authenticated, Mode) returned by the selection helper. - NEW: SelectTemplateAssetFetcher(isSaaSTenant, baseURL, token) — the selection matrix: * isSaaSTenant() && token != "" -> real Gitea, Authenticated=true * isSaaSTenant() && token == "" -> real Gitea, Authenticated=false (the public-fetch activation: molecule-ai/* PUBLIC templates) - !isSaaSTenant() -> no-op fetcher, Authenticated=false (self-host: cfg.TemplatePath + cfg.ConfigFiles handle locally) The isSaaSTenant func is plumbed in as an argument (not package-level lookup) so the selection is testable in isolation. 2. workspace-server/cmd/server/main.go - NEW: isSaaSDeployment() helper — mirrors handlers.saasMode but is in the main package (handlers is unexported; main is a separate package). Resolution: MOLECULE_DEPLOY_MODE first, MOLECULE_ORG_ID fallback (same as handlers.saasMode). - REPLACED the env-var-gated wiring (`if token != "" { SetGiteaTemplateFetcher(...) } else { disabled }`) with the new selection-helper call: sel := provisioner.SelectTemplateAssetFetcher(isSaaSDeployment, baseURL, token) wh.SetGiteaTemplateFetcher(sel.Fetcher) The log line is now driven by sel.Mode + sel.Authenticated (3 explicit modes: "self-host-noop", SaaS-with-token, SaaS-without-token). The fetcher is wired on EVERY boot (no-token case = public-fetch, not disabled). 3. workspace-server/internal/provisioner/template_assets_test.go - NEW: TestSelectTemplateAssetFetcher_SaaS_GiteaFetcher: with-token and without-token (public-fetch) SaaS cases - NEW: TestSelectTemplateAssetFetcher_SelfHost_NoopFetcher: self-host selection, plus Load() returns (nil, nil) - NEW: TestSelectTemplateAssetFetcher_NilSaaSCheck_FallsBackToNoop: nil isSaaSTenant closure safely falls back to no-op VERIFICATION ============ - go build ./... -- clean - go vet ./cmd/server/ ./internal/provisioner/ -- clean - gofmt -l -- clean (all 3 files) - go test ./internal/provisioner/ -- 0.141s, all green - go test ./internal/handlers/ -- 26.1s, all green (no regression) - 3 new selection tests pass DEFERRED (CP-side or follow-up PRs) ==================================== The user's PR-B scope included 3 more pieces that are NOT in this commit because they depend on out-of-this-repo or defer-until-CTO-signoff surfaces: (a) "writes assets to /configs (writeFileViaEIC + copyFilesToContainer)": - LOCAL Docker path (provisioner.go WriteFilesToContainer for ConfigFiles): needs a sibling WriteTemplateAssetsToContainer helper. The current code does NOT write TemplateAssets to /configs on the local path (only the SaaS wire field is populated). DEFERRED to a follow-up PR that integrates TemplateAssets into the local Start() flow. - HANDLER SaaS path (writeFileViaEIC): the templates handler already has the writer, but the actual /configs write on SaaS happens in the CONTROLPLANE (molecule-controlplane, a separate repo). The wire field TemplateAssets on cpProvisionRequest is the molecule-core side of the contract. The CP-side change is owned by the controlplane team. - PR-B's contribution on the molecule-core side: set up the selection + wire field. The CP-side handler is a controlplane follow-up. (b) "REMOVES Secrets-Manager as the config/asset transport": - The substantive change happens in the controlplane: the CP currently stages ConfigFiles through AWS Secrets Manager (with the 256 KiB cap). The PR-B intent is: assets that came from the fetcher (TemplateAssets) should NOT be staged through SM (use a non-secret channel: S3 non-secret bucket, Gitea asset pin, etc.). The controlplane owns the SM removal; this repo's contribution is the wire field + the selection that lets the CP route assets differently. - The 7d508035 CTO sign-off gates the SM-removal specifically. Per the dispatch, PR-B cannot merge until 7d508035 lands. Driver will personally review the SM-removal once the CP change is in. (c) "Infisical read-only template-repo token (env/secret-projection)": - The current code uses MOLECULE_TEMPLATE_REPO_TOKEN env var (main.go:694 templateRepoToken()). This IS the env-projection point — the env var is set by the operator's Infisical bootstrap (the same pattern as GIT_HTTP_PASSWORD). The pattern is already in place; no code change needed. - Out-of-scope to add explicit Infisical SDK integration (operator-side concern, not a molecule-core change). (d) "fetcher selection: real Gitea for SaaS, no-op for self-host": - THIS COMMIT. No-op fetcher type + selection helper + main.go wiring + 3 tests. Done. (e) e2e tests (the user mentioned driver owns e2e verification): - Driver's verification per the dispatch is the 716 KB seo-all on /configs sanity check. That's the driver's e2e lane. - Unit tests in this repo: 3 selection tests + 7 fetcher tests (gitea_template_assets_test.go) + 2 cap tests (template_assets_test.go) + the existing TestWorkspaceCreate + TestWorkspaceUpdate + the rest of the handlers suite (26.1s all green). I added what the molecule-core unit surface can pin; the e2e lane is the driver's. MERGE-GATE ============ This PR is the substantive REMOVE-SM ARCH change which is exactly what RFC #2843's CTO sign-off (7d508035, STILL PENDING) gates. Per the dispatch: open it for the driver's personal review, but it MUST NOT MERGE until 7d508035 lands. Routing: I am NOT requesting a 2nd-genuine reviewer until sign-off. The driver will personally review. Same posture as #2852 (closed post-driver-decision, branch preserved, work held on gate). netrc/GITEA env-var auth -- no inline tokens. --- workspace-server/cmd/server/main.go | 59 ++++++++++-- .../internal/provisioner/template_assets.go | 91 +++++++++++++++++++ .../provisioner/template_assets_test.go | 69 ++++++++++++++ 3 files changed, 213 insertions(+), 6 deletions(-) diff --git a/workspace-server/cmd/server/main.go b/workspace-server/cmd/server/main.go index af060eb98..7c9ae6740 100644 --- a/workspace-server/cmd/server/main.go +++ b/workspace-server/cmd/server/main.go @@ -63,6 +63,32 @@ import ( "github.com/gin-gonic/gin" ) +// isSaaSDeployment reports whether this tenant platform is +// running in SaaS cross-EC2 mode (mirrors handlers.saasMode; +// duplicated here because the helpers package is unexported +// and main.go is a separate package — would be a cycle). +// +// Resolution order: +// 1.

Result: a SaaS tenant with no MOLECULE_TEMPLATE_REPO_TOKEN got ZERO templates — the public-fetch activation #2903 was created to enable did not work. Fix (the dispatch's recommended path): (a) NewGiteaTemplateAssetFetcher/Load: empty token → UNAUTHENTICATED fetch — the Authorization header is OMITTED ENTIRELY when f.token == "" (do NOT send "token " with an empty value, which Gitea 401s on as a malformed credential). The empty-token Load rejection is removed. (b) FLIP the empty-token security-guard test (TestGiteaTemplateAssetFetcher_RejectsEmptyToken) to assert the new contract: no Authorization header in the outgoing request, Load returns no error, assets are returned. (c) ADD a real HTTP no-token test (TestGiteaTemplateAssetFetcher_EmptyToken_RealHTTP_NoAuthHeader_Success) that pins the load-bearing invariant end-to-end: the server asserts NO Authorization header in the request map (catches a regression to "Authorization: token " empty value, which would Gitea-401 and re-introduce the same runtime defect). The existing TestGiteaTemplateAssetFetcher_HappyPath already pins the non-empty-token path (Authorization: token is set). Selection logic (SelectTemplateAssetFetcher) is unchanged — it was already correct (the bug was in the fetcher impl, not the selector). The Authenticated field is unchanged: still true iff token != "". #2903 stays driver-HELD (RC 11907) until his re-review of this fix commit.
