Tomato Branches Laravel Package

Technical Evaluation

Architecture fit. tomatophp/tomato-branches is a Laravel package (Composer-installable, service-provider registered) from the TomatoPHP ecosystem, which typically means it ships config, migrations, and optional Filament/tomato-admin UI integration. Architecturally it is a natural fit for an existing Laravel monolith or modular app that needs first-class "branch" (organizational unit / lightweight multi-tenancy) scoping on Eloquent models. It is not a standalone service and should be evaluated as an in-process domain layer, not infrastructure.

Integration feasibility. High for teams already on Laravel 10/11 with PHP 8.1+. Installation is the standard composer require → publish config/assets → php artisan migrate flow, with model-level trait/scope adoption. v1.0.4 is a patch-level release (1.0.3 → 1.0.4), which by semver convention implies bug fixes only — but the release notes contain only a diff link and no changelog body, so the change surface cannot be confirmed from the artifact provided. Treat "patch = low risk" as an assumption to verify, not a fact.

Technical risk.

• Low: install/rollback, package footprint, upgrade from 1.0.3.
• Medium: coupling to the wider TomatoPHP stack (admin panel/Filament versions), and whether branch scoping is enforced globally via middleware/global scopes or must be applied model-by-model.
• High (unverified): cross-branch data isolation correctness, behavior of existing rows/nullable branch_id during migration, and whether the patch touches migrations already applied in lower environments.
• Supply chain: small-maintainer package; no visible LTS/security policy in the release artifact.

Key questions.

1. What exactly changed between 1.0.3 and 1.0.4 (files, migrations, public API)?
2. Are there new or altered migrations, and are they backwards-compatible with already-migrated databases?
3. Which Laravel/PHP versions and which tomato-admin/Filament versions are supported in this tag?
4. Is branch scoping opt-in per model, or globally enforced? How is the "current branch" resolved (session, middleware, request, job/queue context)?
5. Does 1.0.4 change any public method signatures, config keys, or published migration stubs?

Integration Approach

Stack fit. Assumes Laravel 10/11, PHP 8.1+, MySQL/PostgreSQL. If the application uses Filament or tomato-admin, the package's UI layer aligns; if not, plan to use only the underlying models/traits and skip the published assets. Confirm the package does not pull in the full TomatoPHP admin suite as a hard dependency — that is the single biggest architectural fork in the decision.

Migration path.

1. Pin explicitly to v1.0.4 in composer.json rather than a floating ^1.0 range.
2. Install and run migrations in a disposable/local environment first; diff the generated schema against staging.
3. For an existing dataset, add the branch column as nullable, backfill all rows to a single "default" branch, then tighten constraints in a follow-up migration you own.
4. Wire the "current branch" resolver behind a feature flag so behavior can be toggled per environment.
5. Only after backfill validation, enable global scoping enforcement.

Compatibility. Read the v1.0.3→v1.0.4 diff before upgrading any environment that already runs 1.0.3 — this is the one action the release notes actually enable. Verify Composer constraints (illuminate/*, php) resolve cleanly against the host app with composer why-not. Check that no transitive dependency bump forces a Laravel minor-version jump.

Sequencing. Local → CI → staging with production-like data → production, gated on a rollback rehearsal (migrate:rollback on the package migrations). Because the release is a patch, it can ride the normal dependency-update cadence — no dedicated change window required, provided the diff review comes back clean.

Operational Impact

Maintenance. Low ongoing effort if adopted narrowly (models + middleware). Budget recurring time for: tracking upstream releases (cadence appears active), re-publishing config/migrations after upgrades, and reviewing diffs manually since the release notes are not descriptive. Add a Renovate/Dependabot rule scoped to this package with manual approval required.

Support. Community/GitHub-issues only — no vendor SLA, no commercial backing indicated. For a business-critical data-isolation layer, that is the main operational exposure. Mitigation: fork-and-patch capability, or wrap the package behind an internal interface so it can be replaced.

Scaling. Branch-scoped queries need a composite index on (branch_id, ...) for every hot table; without it, global scopes silently degrade read performance as branch count grows. Watch for N+1 patterns introduced by branch resolution on every request — cache the resolved branch per request/job. Queue and scheduled-command contexts must propagate branch context explicitly or background jobs will execute unscoped.

Failure modes.

• Cross-branch data leakage — the highest-severity failure; caused by a missing global scope on a new model or an unscoped raw query. Requires a test that asserts isolation on every branch-aware model.
• Migration drift — package-published migrations conflicting with app-owned schema; mitigated by copying migrations into the app and treating them as owned code.
• Silent no-op scoping — middleware not registered in a given context (console, queue, API guard), yielding full-table reads.
• Upgrade breakage — a patch release altering a published stub or config key; caught only by diff review.

Ramp-up. Low for a Laravel-fluent engineer: half a day to install, read the service provider and traits, and stand up a two-branch sample. Add one to two days to design the backfill and isolation test suite for an existing production dataset. Documentation quality should be assessed directly from the repo README and the v1.0.3→v1.0.4 diff, since this release ships none.
