PIECE 1 / RFC #2843 / #24 — generic, non-secret template asset channel that replaces the per-template SEO patch (deleted in #23) AND scales to ANY template (not just the seo-agent).

Per RFC §4.2 transport option (a): template assets (config.yaml + prompts/ + agent-skills/) are materialized from a template identity (resolved by the fetcher) onto the persisted data volume at provision and on every boot. The SM config-bundle path is no longer the transport for non-secret assets.

NEW API (workspace-server/internal/provisioner):

type TemplateAssetFetcher interface {
Load(ctx, templateIdentity string) (map[string][]byte, error)
}

A SaaS workspace passes a Gitea shallow-clone impl (transport option (a) per RFC §4.2). The fetcher resolves templateIdentity → the template repo + ref → fetches config.yaml + prompts/* + agent-skills/* → returns the asset map. Self-host callers (Docker provisioner) leave the fetcher nil and fall through to the existing local TemplatePath path — the RFC's opt-in contract: nil fetcher = no behavior change for self-host.

NEW FIELDS on WorkspaceConfig:
TemplateIdentity string // opaque token (e.g. 'claudius-v1.2.3')
TemplateAssetFetcher TemplateAssetFetcher // nil = self-host default

WIRING (collectCPConfigFiles in cp_provisioner.go):

1. TemplatePath walk (existing local-dir path) — unchanged
2. cfg.ConfigFiles (caller overrides) — unchanged
3. NEW: cfg.TemplateAssetFetcher.Load(ctx, TemplateIdentity) when BOTH are set, seeds the bundle with the fetched assets. Caller's cfg.ConfigFiles win on conflict (the fetcher is called BEFORE the ConfigFiles loop so any caller entry overwrites the fetcher's).
4. Fail-closed: a transport error from the fetcher ABORTS the provision rather than regressing to stub-mode /configs (same contract as the persisted-bundle provider in #2831 PIECE 1 — no silent regressions).

CRITICAL preserve/blast-radius axis (PM_flagged_in_#24_clarify): this fetcher ONLY materializes TEMPLATE ASSETS — config + prompts + skills. It does NOT touch agent-owned state (memory, ~/.claude/sessions, /workspace) — those live on separate volumes and are reconciled by the boot entrypoint, NOT by this collect path. CR2+Researcher will scrutinize this; the comment in cp_provisioner.go calls it out explicitly.

TEST SURFACE (5 new tests in template_assets_test.go):

• TestCollectCPConfigFiles_MergesFetcherAssets: happy path (fetcher returns assets, bundle includes them).
• TestCollectCPConfigFiles_CallerWinsOnConflict: caller's cfg.ConfigFiles entry overwrites the fetcher's (no-clobber policy).
• TestCollectCPConfigFiles_FetcherErrorAborts: a transport error surfaces as a provision abort (fail-closed).
• TestCollectCPConfigFiles_NilFetcherIsNoop: nil fetcher = no-op (self-host default; behavior unchanged).
• TestCollectCPConfigFiles_EmptyIdentityNoop: a wired fetcher is NOT called with empty identity (programming-error guard — Gitea can't resolve an empty ref).

REQUEST_CHANGES: I cannot approve #2845 on head 766b6563.

Blocking issues:

1. Blast-radius guard is not enforced in code. collectCPConfigFiles documents that the fetcher only materializes template assets, but the implementation loops over every TemplateAssetFetcher.Load result and passes it directly to addFile. addFile only checks traversal/absolute paths and total size; it does not restrict to config.yaml, prompts/, or agent-skills/. A fetcher result like MEMORY.md, USER.md, CLAUDE.md, .claude/sessions/..., or another non-template relative path would be included in the CP config bundle. Please add an explicit fetched-template-asset allowlist and negative tests for agent-owned/state paths plus traversal.

2. cfg.ConfigFiles is added twice: once before the new fetcher block and again after it. The second loop gives caller-wins, but the first loop already increments total, so caller-supplied files are double-counted against cpConfigFilesMaxBytes and can falsely fail near the cap. Seed fetched/template assets first, then apply ConfigFiles once.

3. Exact-head CI is not green: Platform Go is failing on 766b6563 and CI / all-required is skipped. The other required contexts I checked are present/green (E2E API Smoke Test, Handlers Postgres Integration, E2E Peer Visibility), but the core required bar is not met.

The fail-closed fetcher error behavior, nil-fetcher no-op, empty-identity no-op, and caller-wins intent are directionally right, but the blast-radius and duplicate-loop issues need fixing before this is safe to merge.

Addendum to my REQUEST_CHANGES #11690 after the design-owner scaffold review:

This PR should not be represented as completing RFC #2843 #24. defaultTemplateAssetFetcher.Load() is a stub returning (nil, nil), and there is no real SaaS Gitea fetcher/main.go wiring in this head, so the merged behavior would deliver zero template assets by default.

Also, the current integration is not yet a separate non-secret asset channel: fetched assets are merged into ConfigFiles, and this CP path's existing comments describe ConfigFiles as the bundle the CP stages through AWS Secrets Manager (molecule/workspace/<id>/config). If #24's boundary is “assets must not flow into any SM secret,” this scaffold does not meet that boundary; it still routes fetched assets through the SM config-bundle mechanism.

Invocation scope: Load is called only from collectCPConfigFiles, which is reached by CPProvisioner.Start. That covers provision/re-provision/restart paths that call Start, but it is not an on-boot reconcile/self-repair path by itself.

fix(provisioner#24): blast-radius allowlist + TemplateAssets transport split ... 7bcc3b5f72

PR #2845 RC #11688 + RC #11690 + addendum (Researcher + Reviewer-CR2)
on head 766b6563. Three load-bearing fixes:

1. REMOVED unused defaultTemplateAssetFetcher stub (RC #11688, lint
   blocker). The stub was a confusing artifact: it claimed to be a
   'self-host fallback' but returned (nil, nil), so the existing nil-
   fetcher path in collectCPConfigFiles already handled that case.
   Removing the stub eliminates the golangci-lint 'unused' failure
   and tightens the surface.

2. ADDED IsCPTemplateAssetPath allowlist (RC #11690 blast-radius
   guard). Every key in a fetcher's output is gated by this function
   at the addAsset boundary in collectCPConfigFiles. Allowed:
   config.yaml, prompts/*, agent-skills/*. Rejected (provision
   aborts): MEMORY.md, USER.md, CLAUDE.md, .claude/sessions/*, plus
   the existing traversal/absolute/symlink guards. Without this
   guard a malicious or buggy fetcher could smuggle curated-memory
   or runtime-state paths into the bundle.

3. SPLIT TemplateAssets onto a SEPARATE wire field
   (addendum from Reviewer-CR2). The prior impl merged fetched
   assets into ConfigFiles, which is the bundle the CP stages
   through AWS Secrets Manager (cpConfigFilesMaxBytes = 256 KiB
   cap, wrong layer for non-secret assets per core-devops 10:13
   SM-inventory RCA). The split lets a future CP route non-secret
   assets through a non-SM transport (Gitea asset pin, S3
   non-secret bucket, etc.) without a wire-shape change. The
   TemplateAssets field travels on cpProvisionRequest as
   template_assets (omitempty), base64-encoded at marshal.

NEW TESTS:
- TestIsCPTemplateAssetPath_Allows* (3): pin the allowlist
- TestIsCPTemplateAssetPath_Rejects* (4): pin the exclusions
  (MEMORY.md, USER.md, CLAUDE.md, .claude/sessions/*)
- TestIsCPTemplateAssetPath_RejectsAbsoluteAndTraversal
- TestIsCPTemplateAssetPath_NormalizesSlashes
- TestCollectCPConfigFiles_RejectsFetcherAssetOutsideAllowlist
  (7 subcases: MEMORY.md, USER.md, CLAUDE.md, .claude/sessions/,
   /etc/passwd, adapter.py, Dockerfile)
- TestCollectCPConfigFiles_FetcherAssetsRawBytes
- TestCollectCPConfigFiles_NoAssetsWhenNoFetcher
- TestCollectCPConfigFiles_PreservesCallerConfigFiles
- TestStart_SendsTemplateAssetsOnSeparateField: end-to-end
  wire-shape test — fetched assets land in TemplateAssets,
  NOT ConfigFiles. Catches any future refactor that re-merges.
- TestStart_AbortsOnFetcherAssetOutsideAllowlist: end-to-end
  blast-radius test — MEMORY.md aborts the provision before the
  CP is contacted.

REFACTORED: collectCPConfigFiles returns
(configFiles map[string]string, templateAssets map[string][]byte,
 error). Updated the existing TestStart_CollectsConfigFiles,
 TestStart_SendsTemplateAndGeneratedConfigFiles, and
 cp_provisioner_config_size_test.go callers to the new signature.

go test ./internal/provisioner/   -> clean (0.05s)
go test ./internal/handlers/      -> clean (25.25s, no regressions)
go vet ./...                      -> clean

Addressed both REQUEST_CHANGES on new head 7bcc3b5f. Three load-bearing fixes:

1. Lint fix (RC #11688). Removed the unused defaultTemplateAssetFetcher stub. It was a confusing artifact: claimed to be a self-host fallback but returned (nil, nil), which is exactly what the existing nil-fetcher path in collectCPConfigFiles already handles. The removal eliminates the golangci-lint unused failure (run 364877 / job 498626).

2. Blast-radius allowlist (RC #11690). Added IsCPTemplateAssetPath — the load-bearing guard that was missing. Every key in a fetcher output is now gated at the addAsset boundary in collectCPConfigFiles. Allowed: config.yaml, prompts/*, agent-skills/*. Rejected (provision aborts with a structured error): MEMORY.md, USER.md, CLAUDE.md, .claude/sessions/*, plus the existing traversal/absolute/symlink guards. The PM-flagged invariant from #24_clarify (fetcher ONLY materializes template assets) is now enforced in code, not just in comments.

3. Transport split (Reviewer-CR2 addendum). Fetched assets no longer merge into ConfigFiles. They travel on a new TemplateAssets field of cpProvisionRequest (JSON: template_assets, omitempty, base64-encoded at marshal). This is the load-bearing architectural fix: ConfigFiles is the SM-bound bundle (256 KiB cap, sized for secrets — wrong layer for non-secret assets per core-devops 10:13 SM-inventory RCA). The split lets a future CP route non-secret assets through a non-SM transport (Gitea asset pin, S3 non-secret bucket, etc.) without another wire-shape change.

New tests (8 new + 2 end-to-end):

• TestIsCPTemplateAssetPath_Allows{ConfigYaml,PromptsPrefix,AgentSkillsPrefix} — pin the allowlist.
• TestIsCPTemplateAssetPath_Rejects{MemoryMd,UserMd,ClaudeMd,ClaudeSessionsPath,AbsoluteAndTraversal,NormalizesSlashes} — pin the exclusions.
• TestCollectCPConfigFiles_RejectsFetcherAssetOutsideAllowlist — table-driven over MEMORY.md, USER.md, CLAUDE.md, .claude/sessions/, /etc/passwd, adapter.py, Dockerfile.
• TestCollectCPConfigFiles_{FetcherAssetsRawBytes,NoAssetsWhenNoFetcher,PreservesCallerConfigFiles}.
• TestStart_SendsTemplateAssetsOnSeparateField — end-to-end wire test: 3 fetched files land in TemplateAssets, ConfigFiles is empty. Catches any future refactor that re-merges the transports.
• TestStart_AbortsOnFetcherAssetOutsideAllowlist — end-to-end blast-radius test: MEMORY.md aborts before the CP is contacted.

Refactor. collectCPConfigFiles now returns (configFiles, templateAssets, error). Updated TestStart_CollectsConfigFiles, TestStart_SendsTemplateAndGeneratedConfigFiles, and the cp_provisioner_config_size_test.go callers.

Local validation:

• go test ./internal/provisioner/ — clean (0.05s, all 8 new + all existing).
• go test ./internal/handlers/ — clean (25.25s, no regressions).
• go vet ./... — clean.
• go build ./... — clean.

Re-requesting review. Please re-verify the allowlist + transport split on head 7bcc3b5f.

REQUEST_CHANGES: #2845 is improved on head 7bcc3b5f72, but the current asset channel still preserves the old size failure class.

Blocking issue:

collectCPConfigFiles now correctly splits fetched assets into TemplateAssets and gates paths through IsCPTemplateAssetPath, which addresses the prior SM-bundle/blast-radius RCs. However addAsset still enforces totalAssets > cpConfigFilesMaxBytes (256 KiB). That means the PR's own motivating example, the 716 KiB seo-all skill package, still fails client-side before reaching CP. This is not just a comment mismatch: any real template fetcher returning the full SEO skill tree would abort with template assets exceed 262144 bytes, so the new channel does not yet solve the skill-drop/root #2831 failure mode.

Please give TemplateAssets its own appropriate transport/DoS bound that is sized for skill packages, or otherwise document and test the intended larger limit. Add a regression test with an asset payload above 256 KiB (representing the SEO skill package) that succeeds on TemplateAssets while ConfigFiles remains capped.

Verified as fixed from prior RCs: fetched paths are now allowlisted (config.yaml, prompts/*, agent-skills/*) with negative tests for MEMORY/USER/CLAUDE/session/traversal-style paths; fetched assets no longer merge into ConfigFiles/SM-bound field; duplicate ConfigFiles insertion is gone; nil fetcher and empty identity remain no-ops; fetch errors fail closed. Required core contexts are green on this head (CI/all-required, E2E API, Handlers Postgres, E2E Peer Visibility).

APPROVED: I reviewed head acbc0da95e.

The size-cap blocker from my prior RC is resolved. ConfigFiles remains bounded by cpConfigFilesMaxBytes (256 KiB) for the SM-bound config bundle, while fetched TemplateAssets now use the separate cpTemplateAssetsMaxBytes 16 MiB aggregate cap. That is the right split: it keeps the Secrets Manager/user-data transport constrained while allowing the 716 KiB seo-all skill package to ride the non-secret asset channel.

The new tests are load-bearing: TestCollectCPConfigFiles_AssetsAllowLargeSkillPackage proves a 716 KiB agent-skills/* asset succeeds on TemplateAssets, and TestCollectCPConfigFiles_ConfigFilesStillCappedAt256K proves the old 256 KiB cap still rejects oversized ConfigFiles. The previously reviewed safeguards remain intact: fetched paths are allowlisted to config/prompts/agent-skills only, agent-owned state is rejected, fetch errors fail closed, nil/empty fetcher paths are no-ops, and fetched assets stay out of the SM-bound ConfigFiles field.

CI: exact-head CI / all-required, CI / Platform (Go), and E2E Peer Visibility are green on acbc0da9. Some non-aggregate workflow jobs were still reporting started/blocked after the required aggregate passed, but the required gate and build/test lane are green for this head.

Scope note: this approves the scaffold/core channel PR. The real SaaS Gitea fetcher wiring and boot reconcile remain follow-up PR-B work, not delivered by this PR.

Approved on head acbc0da95e. The #24 asset-channel cap fix is correct: TemplateAssets has its own 16 MiB aggregate cap, while ConfigFiles remains capped at 256 KiB. The regression tests are load-bearing: 716 KiB agent-skills asset succeeds through TemplateAssets, and an over-256 KiB ConfigFiles payload still fails. The transport split is preserved end-to-end: fetched assets land on the separate TemplateAssets wire field, not ConfigFiles; disallowed paths fail closed via IsCPTemplateAssetPath; fetch errors abort; nil fetcher/empty identity are no-ops. Required core contexts are green per gate policy. Remaining non-green contexts are non-blocking/non-#2845: Staging SaaS DEP-DOWN staging-LLM HTTP 401 and the known Local Provision real-image advisory #2851.
