k, let's imagine we want to do 3 (auto-register domains) and 4 (extract generated files from repo). Give some really concrete examples of how we would do that, and why it's better.

Thinking

The user wants concrete examples of how to implement: 1. Auto-register domains (instead of editing server_init.go) 2. Extract generated files from repo (with gitattributes merge strategy)

Let me look at the current patterns in more detail to give really concrete examples.

Let me look at the current patterns more closely to give you concrete before/after examples.

No .gitattributes file

Thinking

Now I have all the information I need. Let me write up concrete examples for:

Auto-register domains - showing the before/after pattern
Extract generated files - showing .gitattributes configuration and why it helps

Let me provide really concrete examples.

Assistant2026-01-10T23:39:16.762Z

Now I have the full picture. Here are concrete examples:

1. Auto-Register Domains

The Problem Today

Every time someone adds a new domain manager to ledger, they must:

Add a field to server.go (line ~140-170)
Add an initializeXxxManager() method to server_init.go
Add a call to that method in InitDomains() (line ~987-1075)

This means 3 locations in 2 files that everyone editing domains must touch. When two people add domains in parallel → merge conflict.

Current Pattern (server_init.go:1026-1032)

func InitDomains(ctx context.Context, s *Server, config *config.Config) error {
    // ... 20+ other initializations ...

    if err := s.initializeDelinquencyManager(); err != nil {
        return err
    }

    if err := s.initializeCreditLineOverrideManager(); err != nil {
        return err
    }

    // ... 10+ more initializations ...
}

Every new domain adds 3 lines here. Two PRs adding domains = guaranteed conflict.

Proposed Pattern: Self-Registering Domains

Step 1: Create a registry (new file: ledger/internal/server/registry.go)

package server

import "context"

// DomainInitializer is a function that initializes a domain and attaches it to the server.
type DomainInitializer struct {
    Name string
    Init func(ctx context.Context, s *Server) error
}

// domainRegistry holds all registered domain initializers.
// Domains register themselves via init() functions.
var domainRegistry []DomainInitializer

// RegisterDomain adds a domain initializer to the registry.
// Called from init() functions in each domain package.
func RegisterDomain(name string, init func(ctx context.Context, s *Server) error) {
    domainRegistry = append(domainRegistry, DomainInitializer{Name: name, Init: init})
}

// InitAllDomains runs all registered domain initializers.
func InitAllDomains(ctx context.Context, s *Server) error {
    for _, d := range domainRegistry {
        if err := d.Init(ctx, s); err != nil {
            return fmt.Errorf("failed to initialize domain %s: %w", d.Name, err)
        }
    }
    return nil
}

Step 2: Each domain registers itself (e.g., ledger/internal/domains/delinquencymanager/register.go)

package delinquencymanager

import (
    "context"
    "github.com/go-backend/ledger/internal/server"
)

func init() {
    server.RegisterDomain("delinquency", initDelinquencyManager)
}

func initDelinquencyManager(ctx context.Context, s *server.Server) error {
    manager, err := NewManager(
        WithLogger(s.Logger()),
        WithStats(s.Stats()),
        WithCreditLineDAO(s.SQLDao().CreditLineDAO),
        WithTermsDAO(s.SQLDao().TermsDAO),
        WithFeatureStore(s.FeatureStore()),
    )
    if err != nil {
        return err
    }
    s.SetDelinquencyManager(manager)
    return nil
}

Step 3: Replace InitDomains with the registry call

// server_init.go - InitDomains becomes:
func InitDomains(ctx context.Context, s *Server, config *config.Config) error {
    return InitAllDomains(ctx, s)
}

Step 4: Import all domain packages in one place (ledger/internal/server/domains.go)

package server

// Import all domain packages to trigger their init() registration.
// Add new domains here - this is the ONLY file that needs editing.
import (
    _ "github.com/go-backend/ledger/internal/domains/collectionmanager"
    _ "github.com/go-backend/ledger/internal/domains/creditlineoverridemanager"
    _ "github.com/go-backend/ledger/internal/domains/creditmanager"
    _ "github.com/go-backend/ledger/internal/domains/creditprofilemanager"
    _ "github.com/go-backend/ledger/internal/domains/delinquencymanager"
    _ "github.com/go-backend/ledger/internal/domains/feeprofilemanager"
    _ "github.com/go-backend/ledger/internal/domains/loanmanager"
    // ... etc
)

Why This Is Better

Aspect	Before	After
Files to edit for new domain	2 (`server.go`, `server_init.go`)	1 (`domains.go` import + new `register.go`)
Lines changed in shared files	~15 lines across 2 files	1 import line
Merge conflict probability	High (sequential blocks)	Low (import list is easy to merge)
Domain code locality	Split across 3 locations	All in domain package

The key insight: import lists merge cleanly because git can auto-merge additions to different lines. Sequential if err := ...; return err blocks cannot.

2. Extract Generated Files from Git Merge Conflicts

The Problem Today

Generated files like z_mocks_*.go and z_swagger*.json are: - Changed in 15+ commits out of the last 50 - Regenerated whenever their source changes - Cause merge conflicts that are meaningless (just regenerate!)

Example: Two PRs both add a method to census.proto. Both regenerate z_mocks_census_grpc_client.go. Merge conflict. But the resolution is always: regenerate from merged proto.

Solution: `.gitattributes` Merge Strategy

Create .gitattributes in repo root:

# Generated mock files - always accept "ours" on merge, then regenerate
**/z_mock*.go merge=ours
**/z_mocks_*.go merge=ours

# Generated swagger files - same strategy
api/swagger/z_swagger*.json merge=ours
api/swagger/z_swagger*.yaml merge=ours

# Generated proto files
**/*.pb.go merge=ours

How merge=ours works:

When git encounters a conflict in these files during merge/rebase: 1. Instead of showing conflict markers, it keeps "our" version 2. The merge succeeds without manual intervention 3. CI then regenerates the files from source (proto, interfaces)

Required CI step (add to PR workflow):

# .github/workflows/pr-checks.yml
- name: Regenerate and verify generated files
  run: |
    # Regenerate mocks
    go generate ./...

    # Regenerate swagger
    ./scripts/generate-and-validate-swagger.sh

    # Fail if there are uncommitted changes (generated files out of sync)
    git diff --exit-code || (echo "Generated files out of sync. Run 'go generate ./...' and commit." && exit 1)

Alternative: Don't Commit Generated Files At All

A more aggressive approach: add generated files to .gitignore and generate them in CI/locally.

.gitignore additions:

# Generated mocks - regenerate with 'go generate ./...'
**/z_mock*.go
**/z_mocks_*.go

# Generated swagger - regenerate with './scripts/generate-and-validate-swagger.sh'  
api/swagger/z_swagger*.json
api/swagger/z_swagger*.yaml

Makefile target for local dev:

.PHONY: generate
generate:
    go generate ./...
    ./scripts/generate-and-validate-swagger.sh

.PHONY: setup
setup: generate
    # Other setup steps...

Why This Is Better

Approach	Merge Conflicts	Repo Size	Dev Experience
Current (commit all)	Frequent	Larger (+1003 mock files)	Simple but conflict-prone
`merge=ours` + CI check	None	Same	Auto-resolves, CI validates
`.gitignore` generated	None	Smaller	Must run `make generate`

Recommendation: Start with merge=ours + CI validation. It's less disruptive than removing files from git entirely, but eliminates the merge conflict problem.

Concrete Before/After

Before (typical merge conflict in z_mocks_census_grpc_client.go):

<<<<<<< HEAD
func (_m *MockCensusClient) ListCreditLinesByDebtSale(ctx context.Context, ...) {
=======
func (_m *MockCensusClient) BulkUploadDebtSaleCreditLine(ctx context.Context, ...) {
>>>>>>> feature-branch

Developer must: understand both changes, manually merge, hope they got it right.

After (with merge=ours):

# Merge succeeds automatically
# CI runs go generate
# CI commits regenerated file (or fails if source is wrong)

No manual intervention. The generated file is always correct because it's regenerated from the merged source.

Migration Path

Week 1: Add `.gitattributes` for generated files

Zero risk, immediate benefit
Merge conflicts in z_* files disappear

Week 2-3: Pilot domain registry in ledger

Create registry.go
Migrate 2-3 domains to self-registration
Keep old InitDomains working for non-migrated domains

Week 4+: Roll out to other services

Apply same pattern to census, onboard, teller
Each service can migrate incrementally
