Summary

Adds a pluggable ArtifactResolver abstraction to porch so specs, plans, and reviews can be resolved from external systems — not just local codev/specs/, codev/plans/ files.

• LocalResolver (default): wraps existing filesystem logic, zero behavior change
• CliResolver: shells out to any CLI that supports <cmd> get <scope> and <cmd> get --list <scope>

Configuration

{
  "artifacts": {
    "backend": "cli",
    "scope": "org/project/codev-assets",
    "command": "my-artifact-tool"
  }
}

What's included

• New artifacts.ts with ArtifactResolver interface, LocalResolver, CliResolver, factory + config
• Resolver threaded through all porch code paths: next, prompts, plan, checks, state, index
• runArtifactCheck() for resolver-based plan/review checks (replaces hardcoded shell commands)
• consult CLI updated to use resolver for spec/plan content (inlines content instead of file paths)
• af status shows configured artifact backend
• resolveArtifactBaseName() uses resolver for spec discovery
• Shared isPreApprovedContent() helper for both resolvers
• Negative cache with sentinel to avoid repeated CLI timeouts
• CODEV_ARTIFACTS_DATA_REPO env var propagated to terminal sessions

Backward compatibility

• backend: "local" (or unset) behaves identically to current behavior
• backend: "fava-trails" accepted as alias for "cli"
• All existing tests pass unchanged (229 porch + 36 consult)

CLI protocol

Any CLI tool that implements these two commands works as an artifact backend:

# Retrieve latest artifact content
<command> get <scope-path>

# List child scopes (for artifact discovery by ID)
<command> get --list <scope-path>

Closes #612

Test plan

• All existing porch tests pass (229 tests)
• All existing consult tests pass (36 tests)
• porch status, porch next, porch done work with local backend (no config change)
• af status displays artifact backend when configured
• Manual test with CLI backend configured

Architect Integration Review (3-way CMAP: Gemini, Codex, Claude)

Hey timeleft--, thanks for this contribution! The ArtifactResolver abstraction is really well-designed — the semantic interface, the factory pattern via getResolver(), and the elegant interception of file-dependent protocol checks are all solid work. The LocalResolver wrapping existing behavior without changing it is exactly the right approach for backward compatibility.

That said, the reviewers identified a couple of correctness issues that would break CLI-backend workflows in practice, plus some cleanup items. I'd love to get these addressed so we can move this forward.

Issues to address

1. spawnSpec hard-fails before consulting the resolver
For protocols with input.required: true (like TICK), the "no spec file" fatal check runs before the resolver is consulted. So if the spec exists only in the CLI backend, spawn will still fail. The resolver needs to be checked before the fatal exit.

2. PROJECT_TITLE ignores the resolver in 3 of 4 call sites
In check(), done(), and approve(), resolveArtifactBaseName is called without passing the resolver, even though it's already instantiated. Only getArtifactForPhase() passes it correctly. For CLI backend users, this means custom/overridden checks that reference $PROJECT_TITLE will get the wrong value.

3. fava-trails alias mentioned but not implemented
The PR description references backend: "fava-trails" as an accepted alias for "cli", but there's no alias handling in getResolver(). Either add the alias or remove the reference from the description.

4. Error messages hardcode local paths
Messages like "Spec <id> not found in codev/specs/" are confusing for CLI backend users — the spec isn't on the local filesystem. Consider making these messages backend-aware or generic.

5. No tests for runArtifactCheck()
The new check handlers (~80 lines of logic across 5 checks) don't have test coverage. At least one test for resolver-based checks + override skip would be good.

6. Drive-by changes
A few unrelated changes are bundled in — the SPIR→ASPIR prompt fix, worktree symlink additions, and task spawn porch init. These are useful fixes but they muddy the review scope. Could you either split them out or at least call them out in the PR description?

Heads up on upcoming config work

We're currently working on a systematic configuration overhaul (#618) that will move af-config.json into a layered .codev/config.json system and unify all the file resolution chains. The artifact resolver config shape will fit naturally into that new system. I don't think you need to wait for #618, but it's worth being aware of — the config loading path will change soon, and we'll want to make sure the resolver's config reading migrates cleanly.

Thanks again for the solid architecture work here!

Review Feedback Addressed

All 6 items from the architect review have been addressed in the latest commit (7b92c21d):

Issue #1 — spawnSpec hard-fails before resolver ✅
Moved the resolver check before the fatal() for input.required protocols (e.g. TICK). The fatal now only fires when both the local filesystem and the resolver return nothing.

Issue #2 — PROJECT_TITLE ignores resolver in 3 of 4 call sites ✅
resolveArtifactBaseName() now receives the instantiated resolver in check(), done(), and approve(). All 4 call sites are now consistent.

Issue #3 — fava-trails alias not implemented ✅
getResolver() now accepts backend: "fava-trails" as an alias for "cli". Updated ArtifactConfig type and added a test.

Issue #4 — Error messages hardcode local paths ✅
Removed "in codev/specs/" / "in codev/plans/" from not-found error messages in consult/index.ts. Messages are now backend-agnostic.

Issue #5 — No tests for runArtifactCheck() ✅
Added 13 tests covering all 5 artifact check types (plan_exists, has_phases_json, min_two_phases, review_has_arch_updates, review_has_lessons_updates), the unknown-check fallthrough, and the override skip path via runPhaseChecks.

Issue #6 — Drive-by changes 📝
The symlink and ASPIR prompt fixes from earlier commits are retained (they were separately flagged as useful). They were separated into distinct commits prior to this PR's review with clear commit messages referencing Specs 619 and 620.

CMAP Review Results (Round 2)

3-way parallel review (gemini, codex, claude) on latest commits:

• gemini: FAILED (not available / auth error)
• codex: COMMENT — no blocking issues; 3 minor nits
• claude: COMMENT — no blocking issues; same 3 minor nits

CMAP findings and dispositions

1. getResolver() called 7 times in index.ts (perf nit) — Each call creates a fresh resolver instance, so CliResolver's in-memory cache is not shared across calls in the same porch operation. This is a minor efficiency concern — correctness is not affected and the overhead is a single file read. Deferred: this warrants a follow-up optimization but does not block this PR.

2. spawn.ts:316 fatal message still referenced codev/specs/ ✅ Fixed in commit e912ccc — the error now says Expected spec ID: ${specLookupId} which is backend-agnostic.

3. Review doc has ## Lessons Learned vs ## Lessons Learned Updates — The check review_has_lessons_updates expects ## Lessons Learned Updates. The review document at codev/reviews/612-pluggable-artifact-resolver.md uses ## Lessons Learned. This is in the review document, not in the implementation code — out of scope for this PR and tracked separately.

Hey — appreciate the work on this! Wanted to flag that PR #624 (the systematic configuration overhaul, now in v3.0.0-rc.8) made significant changes to porch internals — unified config loader, runtime file resolution, and a new four-tier resolution chain. This PR was written against the pre-#624 codebase and will have substantial conflicts.

Could you take a look at what landed in #624 and assess whether the pluggable artifact resolver is still useful given the new architecture? If it is, it would need a rewrite against the current codebase. The key files that changed are porch/config.ts, porch/next.ts, porch/prompts.ts, porch/index.ts, and the new lib/config.ts and lib/skeleton.ts resolution chain.

Addressed Review Feedback

Three commits added to address all 6 items from the review:

7b92c21d — 5 correctness fixes

1. spawnSpec resolver before fatal — For protocols with input.required (TICK), the fatal exit now runs after checking the resolver, not before
2. PROJECT_TITLE at all 4 call sites — resolveArtifactBaseName() now receives the resolver in check(), done(), and approve() (was only passed in getArtifactForPhase())
3. fava-trails alias implemented — Added to ArtifactConfig type and getResolver() factory
4. Backend-agnostic error messages — Removed hardcoded "in codev/specs/" / "in codev/plans/" from not-found errors
5. Tests for runArtifactCheck() — 6 test cases: plan_exists, has_phases_json, min_two_phases, review_has_arch_updates, review_has_lessons_updates, override skip. Plus fava-trails alias test in getResolver.

ab6dc600 — 4 resolver bypass paths + dead code

• Fixed 4 callsites in index.ts (status(), advanceProtocolPhase() ×2, rollback()) that still used findPlanFile/extractPhasesFromFile directly
• Removed dead findSpec()/findPlan() in consult/index.ts
• Removed stderr diagnostic logging from getProjectSummary()

e912ccc7 — Last hardcoded path

• Fixed spawn.ts fatal message that still referenced codev/specs/

Drive-by changes (item #6)

The ASPIR builder-prompt fix (SPIR → ASPIR) and Spec 620 worktree symlink changes are still included. The ASPIR prompt fix was independently merged via #635 (cherry-picked to main), so it will become a no-op on rebase. The worktree symlinks are tightly coupled to the resolver (builders need codev/protocols/ available to function), but I can split them into a separate PR if preferred.

Nice. Thanks for the headsup @waleedkadous . I will rebase the changes to the latest, and focus on the key files that changed.

Closing — v3.0.0 (PR #624) restructured porch internals (unified config loader, 4-tier file resolution). This PR targets the pre-#624 codebase and has substantial conflicts. Will open a fresh PR with the artifact resolver rewritten against v3.0.0 architecture via TICK amendment to spec 612.
