-
-### Phase 3A — What to Build
-
-Backend and frontend are both net-new for Phase 3A. Nothing exists yet.
-
-**Backend:**
-1. `internal/models/environment.go` — `Environment` (id, repoId, name, url, protectionRules JSON) + `Deployment` (id, envId, repoId, sha, ref, status, triggeredBy, description, runId, startedAt, finishedAt)
-2. `internal/models/migrations/010_environments.go` — `Run010()` syncing both structs; call from `001_init.go`
-3. `internal/api/handlers/environment.go` — `ListEnvironments`, `CreateEnvironment`, `GetEnvironment`, `UpdateEnvironment`, `DeleteEnvironment`, `ListDeployments`, `CreateDeployment`, `UpdateDeploymentStatus`; publish `deployment.*` NATS events
-4. `internal/api/router.go` — wire routes under `/{owner}/{repo}/environments` and `/{owner}/{repo}/environments/{envName}/deployments`
-
-**Frontend:**
-5. `frontend/src/types/api.ts` — add `Environment`, `Deployment`, `DeployStatus` types
-6. `frontend/src/api/queries/environments.ts` — `useEnvironments`, `useEnvironment`, `useCreateEnvironment`, `useUpdateEnvironment`, `useDeleteEnvironment`, `useDeployments`, `useCreateDeployment`, `useUpdateDeploymentStatus`
-7. `frontend/src/pages/EnvironmentsPage.tsx` — environment cards each showing latest deployment status, SHA, who deployed, time; "New environment" flow; deployment history per env
-8. `frontend/src/components/layout/Sidebar.tsx` — add `Environments` nav item between Pipelines and Settings in `RepoSubNav`
-9. `frontend/src/pages/RepoPage.tsx` — surface deployment status badges in the repo header (latest deploy per env at a glance)
-10. `frontend/src/App.tsx` — add route `repos/:owner/:repo/environments`
+| 3C | Workspaces + secret management (Global → Workspace → Repo → Env) | **Complete** |
+| 3D | GitOps controller + drift detection + auto-sync | **Complete** |
+| 3E | Observability (Prometheus `/metrics`, structured `/health`, repo health API) | **Complete** |
+| 3F | Federation handlers (ActivityPub WebFinger, actor, inbox/outbox, HTTP signatures, Follow/Accept) | **Complete** |
+| 4 | SBOM generation, secret scanning, vuln scanning, signed artifacts, OCI registry, security page | **Complete** |
+| 5 | Deployment promotions, rollback visualization | Planned |

-- `Workspace` model — named collaborative namespace (handle, displayName, description, avatarUrl)
-- `WorkspaceMember` model — user membership with owner/admin/member roles
-- Repos can be owned by a workspace; URL format stays `/{owner}/{repo}` where owner is a workspace handle or username
-- `Secret` model — AES-256-GCM encrypted, scoped to global / workspace / repo / env
-- Secret hierarchy resolution in CI executor: Env → Repo → Workspace → Global
-- Full CRUD APIs for workspaces, workspace members, secrets at all scope levels
-- WorkspacesPage, WorkspacePage, WorkspaceSettingsPage (settings + members)
-- Workspace switcher in sidebar header
-- Create repo: workspace owner selector
-- RepoSecretsPage — write-only secret management per repo and per environment

+## [1.0.0] — 2026-05-13
+
+Phase 4 complete. SBOM generation, secret scanning, dependency vulnerability scanning, signed artifacts, and OCI registry are operational.
+
+### Added — SBOM Generation (`internal/domain/sbom/`)
+- **`Generator`** — subscribes to `pipeline.completed` events and auto-generates CycloneDX 1.4 SBOM documents for every successful pipeline run; also supports on-demand generation via `GenerateOnDemand`
+- **6 manifest parsers**: `go.mod`, `package.json`, `requirements.txt`, `Cargo.toml`, `Gemfile.lock`, `pom.xml` — lightweight line-scanning, no external parser dependencies
+- **API endpoints** — `GET /sbom`, `GET /sbom/document`, `GET /runs/{runID}/sbom`, `GET /runs/{runID}/sbom/document`, `POST /sbom/generate?ref=&runID=`
+- **Database** — migration `016_sbom` adds `SBOMReport` model with CycloneDX document body
+- Automatic generation on pipeline completion now also fires directly from the orchestrator (not solely via NATS), ensuring SBOMs are generated even when NATS is unavailable
+
+### Added — Secret Scanning (`internal/domain/scanning/`)
+- **`Scanner`** — subscribes to `push.received` events, scans git diffs against 15 regex patterns for high/medium severity secrets
+- **Secret patterns**: AWS keys, GitHub/GitLab tokens, generic API keys, Bearer tokens, Slack tokens, Google API keys, Google service accounts, SSH private keys, JWTs, NPM tokens, PostgreSQL/Redis connection strings, generic passwords
+- **API endpoints** — `GET /secrets/leaks`, `POST /secrets/leaks/{leakID}/dismiss` (repo-scoped), `GET /api/v1/secrets/leaks` (global admin)
+- **Database** — migration `018_scanning` adds `SecretLeak` model
+
+### Added — Vulnerability Scanning (`internal/domain/vulnscan/`)
+- **`Scanner`** — triggers on-demand scans against the OSV API (`api.osv.dev/v1`); supports scanning by PURL or by fetching the latest SBOM and scanning all components
+- **OSV client** — HTTP client with 30-second timeout, queries OSV database for CVEs by PURL or ecosystem+name, extracts CVSS scores and fixed version ranges
+- **API endpoints** — `GET /vulnerabilities`, `POST /vulnerabilities/scan`, `POST /vulnerabilities/{findingID}/dismiss` (repo-scoped), `GET /api/v1/vulnerabilities` (global admin)
+- **Database** — migration `019_vulnscan` adds `VulnerabilityFinding` model
+- Findings deduplicated by `(vuln_id, purl, repo_id)`
+
+### Added — Artifact Signing (`internal/domain/signing/`)
+- **`KeyStore`** — ECDSA P-256 signing and verification; produces self-verifying `Bundle` carrying payload, signature (ASN.1 DER), and public key PEM
+- `Sign(artifactID, name, rawContent)` — computes SHA-256 digest, signs, returns signed `Bundle` with key ID fingerprint
+- `Verify(bundleJSON)` — extracts public key from bundle, verifies ECDSA signature, returns `VerifyResult` with key-matching check
+- `Generate()` — creates ephemeral ECDSA P-256 key when `ARTIFACT_SIGNING_KEY` env var is unset (logs warning; signatures lost on restart unless persisted)
+- **API endpoints** — `GET /artifacts/{artifactID}/signature`, `GET /artifacts/{artifactID}/verify`
+- **Database** — migration `015_signing` adds `ArtifactSignature` model
+
+### Added — OCI Registry (`internal/domain/oci/`)
+- **`Registry`** — content-addressable on-disk blob store implementing OCI Distribution Spec v1.1
+- Storage layout: `{root}/blobs/sha256/<hex>` for blobs, `{root}/uploads/<uuid>` for in-progress uploads
+- Full upload session lifecycle: start (POST), append chunk (PATCH), finalize with digest verification (PUT), cancel (DELETE), offset query (GET)
+- 13 OCI distribution error codes defined (`ErrBlobUnknown`, `ErrDigestInvalid`, `ErrManifestInvalid`, etc.)
+- **API handlers** (`internal/api/handlers/oci.go`, 525 lines) — full `/v2/{name}/{kind}/{ref}` routing: manifest push/get/delete, blob HEAD/get/delete, tag listing, chunked upload
+- **Database** — migration `017_oci` adds `OCIRepository`, `OCIManifest`, `OCITag`, `OCIBlob`, `OCIUpload` models
+- Registry is consumed by standard OCI tools (Docker, Podman, Skopeo, containerd)
+
+### Added — Unified Security Page (`/repos/:owner/:repo/security`)
+- **`RepoSecurityPage`** — single-page view combining SBOM status, secret leak detection, and vulnerability findings
+- SBOM section: displays existing SBOM metadata with download button, or "Generate SBOM" form with branch/SHA input
+- Secret Leaks section: lists leaks with severity badge, pattern name, commit SHA, ref, match sample, dismiss button
+- Vulnerabilities section: lists findings with CVSS severity (CRITICAL/HIGH/MEDIUM/LOW), vuln ID, score, summary, PURL, version, fix suggestion, dismiss button; "Scan now" trigger
+- **Route** added in `App.tsx`, nav link added in `RepoPage.tsx` tab bar
+
+### Added — Pipeline Run SBOM Integration
+- `PipelineRunPage` shows per-run SBOM section: metadata (components, SHA, generation time) + download button
+- "Generate SBOM" button for completed/failed runs that lack one
+- `useRunSBOM` / `useGenerateSBOM` hooks in `frontend/src/api/queries/sbom.ts`
+- 404 from `useRunSBOM` handled gracefully (returns `null` instead of throwing)
+
+### Added — Database Models
+- Migration `016_sbom` — `SBOMReport` (repoId, runId, sha, format, componentCount, bomDocument, generatedAt)
+- Migration `017_oci` — `OCIRepository`, `OCIManifest`, `OCITag`, `OCIBlob`, `OCIUpload`
+- Migration `018_scanning` — `SecretLeak` (repoId, commitSha, ref, patternName, description, severity, matchSample, dismissed, dismissedBy, dismissedAt, detectedAt)
+- Migration `019_vulnscan` — `VulnerabilityFinding` (repoId, vulnId, purl, version, summary, details, cvssScore, fixedVersion, dismissed, dismissedBy, dismissedAt, detectedAt)
+- Migration `020_forgefed` — repository + pull request column updates
+
+### Fixed
+- SBOM per-run download endpoint (`/runs/{runID}/sbom/document`) was registered at the wrong router nesting level, causing a route conflict with the `GetLatestDocument` handler. Moved into the correct `/runs/{runID}` route block.
+- `username` context key extraction in scanning and vulnerability handlers changed from raw string `"user"` to typed `middleware.ContextKeyUsername`
+- Nil-safe `Needs` marshalling in orchestrator job creation
+- Nil-safe findings response in vulnerability scan API
+- `GenerateOnDemand` SBOM cache key now includes `runID` to prevent per-run generation from being shadowed by prior on-demand generation

+
+## [0.9.0] — 2026-05-12
+
+Phase 3F complete. ForgeBucket is now a first-class ActivityPub node — interoperable with Mastodon, Forgejo, and any fediverse server.
+
+### Added — ActivityPub Federation (`internal/domain/federation/`)
+
+- **`GET /.well-known/webfinger`** — resolves `acct:user@domain` to the actor URL; returns `application/jrd+json`
+- **`GET /users/{username}`** — returns a JSON-LD actor document (`Person` type) including public key object for HTTP signature verification
+- **`POST /users/{username}/inbox`** — receives and dispatches inbound ActivityPub activities; HTTP signature verification enforced in production (skipped in `DEBUG=true` mode for local testing)
+- **`GET /users/{username}/outbox`** — serves an `OrderedCollection` (summary on page 0, paginated `OrderedCollectionPage` on page ≥ 1, 20 activities per page)
+- **`GET /users/{username}/followers`** — stub `OrderedCollection` (zero items; social graph in Phase 4)
+- **`GET /users/{username}/following`** — stub `OrderedCollection`
+
+### Added — HTTP Signatures (`internal/domain/federation/signatures.go`)
+- `Sign(req, keyID, privateKeyPEM)` — signs outgoing HTTP requests with RSA-SHA256; covers `(request-target)`, `host`, and `date` headers
+- `Verify(r, db, instanceURL)` — parses `Signature` header, resolves sender's public key (local `FederationActor` first, then network fetch via `FetchActor`), verifies RSA-SHA256 digest
+
+### Added — Actor Lifecycle (`internal/domain/federation/actor.go`)
+- `GetOrCreate` — lazily creates a `FederationActor` for a local user; generates a fresh RSA-2048 key pair and derives `InboxURL`, `OutboxURL`, `APID` from `INSTANCE_URL`; stable across requests
+- `ActorJSON` — returns the JSON-LD document shape expected by all ActivityPub clients
+- `APID(instanceURL, username)` — canonical `{instanceURL}/users/{username}` helper
+
+### Added — Follow / Accept Flow (`internal/domain/federation/inbox.go`)
+- Incoming `Follow` activities are auto-accepted: remote actor is fetched (or retrieved from cache), an `Accept` activity is signed and delivered to their inbox asynchronously
+- Both the inbound `Follow` and outbound `Accept` are persisted to `FederationActivity` for audit
+
+### Added — Remote Actor Cache (`internal/domain/federation/remote.go`)
+- `FetchActor` — HTTP GET with `Accept: application/activity+json`, extracts inbox URL and public key PEM, stores in `RemoteActor` table to avoid repeated fetches
+- `DeliverActivity` — marshals activity JSON, signs the request, POSTs to recipient inbox with 15-second timeout
+
+### Added — Database Models (migration `014_federation`)
+- `FederationActivity` — append-only log of all inbound and outbound activities: `ActorAPID`, `Type`, `ObjectJSON`, `Direction` (inbound/outbound), `RemoteActor`, `Published`
+- `RemoteActor` — cache for remote actor documents: `APID` (unique), `InboxURL`, `PublicKey`, `FetchedAt`
+
+---
+
+## [0.8.0] — 2026-05-12
+
+Phase 3E complete. Prometheus metrics, structured health checks, and per-repo operational health are operational.
+
+### Added — Prometheus Metrics (`internal/observability/`)
+- `GET /metrics` — Prometheus text format endpoint (standard root-level path for k8s/Prometheus scraping)
+- `GET /health` — upgraded from static `{"status":"ok"}` to a structured liveness response:
+  `{"status":"healthy","checks":{"database":"ok","nats":"ok"},"version":"0.8.0"}`
+  Returns HTTP 503 when any dependency is degraded
+- `internal/observability/metrics.go` — metric definitions:
+  - `forgebucket_http_requests_total{method,path,status}` — counter
+  - `forgebucket_http_request_duration_seconds{method,path}` — histogram (Prometheus default buckets)
+  - `forgebucket_pipeline_runs_total{status}` — counter (succeeded/failed/cancelled), pre-initialized to 0
+  - `forgebucket_deployments_total{status}` — counter (pending/success/failure/cancelled), pre-initialized to 0
+  - `forgebucket_active_pipeline_runs` — gauge (in-flight runs)
+- `internal/observability/health.go` — `Check(db, bus)` pings PostgreSQL and calls `bus.Healthy()`
+- HTTP instrumentation middleware inserted after `Recoverer`, before `CORS` — records every request
+- Path normalization prevents label cardinality explosion: `/repos/alice/myrepo/runs/42` →
+  `/api/v1/repos/:owner/:repo/runs/:id`
+- NATS metric watcher subscribes to `pipeline.>` and `deployment.>` and increments counters
+
+### Added — Per-Repo Operational Health (`GET /api/v1/repos/{owner}/{repo}/health`)
+- Returns a JSON summary for the repo page operational header:
+  - `ciPassRate7d` — fraction of pipeline runs that succeeded in the last 7 days
+  - `totalRuns7d` — total run count in the last 7 days
+  - `latestRun` — most recent `PipelineRun` record
+  - `latestDeployments` — one entry per environment showing latest deploy (envName, status, sha, finishedAt)
+  - `openDriftCount` — GitOpsConfigs in `drifted` state
+  - `openPRCount` — open pull request count
+
+### Added — EventBus `Healthy() bool`
+- Added to the `EventBus` interface; `NATSBus` returns `nc.IsConnected()`; `NoOpBus` returns `true`
+
+### Changed — Middleware chain
+- `observability.Middleware()` added between `Recoverer` and `CORS` (applies to all requests including `/health` and `/metrics`)
+
+---
+
+## [0.7.0] — 2026-05-12
+
+Phase 3D complete. Git is now the source of truth for environment deployment state.
+
+### Added — GitOps Controller (`internal/domain/gitops/`)
+- `controller.go` — starts as a background goroutine; subscribes to `push.received`,
+  `deployment.succeeded`, `deployment.failed`; runs a periodic reconciliation ticker
+  (interval configurable via `GITOPS_RECONCILE_INTERVAL`); recovers stale `syncing`
+  configs to `drifted` on startup
+- `drift.go` — `CheckDrift` calls `git rev-parse` via the existing git domain wrapper;
+  `handlePush` queries all GitOpsConfigs matching the pushed branch and evaluates drift;
+  `periodicCheck` iterates configs whose `SyncInterval` has elapsed; publishes
+  `environment.drift_detected` when drift is found
+- `reconciler.go` — `TriggerSync` creates a `Deployment` record and publishes
+  `deployment.started` (same lifecycle path as manual deployments, `TriggeredBy="gitops"`);
+  `handleDeploymentSucceeded` resolves open drift events and marks config `synced` for
+  both GitOps and manual deployments; `handleDeploymentFailed` reverts to `drifted`
+
+### Added — GitOps HTTP API (`internal/api/handlers/gitops.go`)
+All routes live under `/api/v1/repos/{owner}/{repo}/environments/{envName}/gitops/`:
+- `GET    /gitops` — current GitOpsConfig or 404 if not configured
+- `PUT    /gitops` — idempotent upsert (branch, autoSync, syncInterval)
+- `DELETE /gitops` — remove config without deleting deployments
+- `POST   /gitops/sync` — manual reconciliation trigger; creates deployment record
+- `GET    /gitops/drift` — current sync status: syncStatus, desiredSha, actualSha, isDrifted
+- `GET    /gitops/drift/history` — paginated drift event log (newest first)
+- `POST   /gitops/drift/{driftID}/acknowledge` — acknowledge without syncing
+
+### Added — Database Models (migration `013_gitops`)
+- `GitOpsConfig` — links environment to a branch; tracks `DesiredSHA`, `ActualSHA`,
+  `SyncStatus` (`unknown/synced/drifted/syncing`), `AutoSync`, `SyncInterval`,
+  `LastCheckedAt`
+- `GitOpsDriftEvent` — append-only drift record: `DesiredSHA`, `ActualSHA`,
+  `SyncStatus` (`drifted/synced/acknowledged`), `DetectedAt`, `ResolvedAt`
+
+### Added — Supporting Changes
+- `git.RevParse(repoPath, ref)` — new function in `internal/domain/git/binary.go`
+  used by `CheckDrift` to resolve branch HEAD SHA
+- `events.DeploymentEvent` + `events.DriftEvent` types added to `internal/events/types.go`
+- `EnvironmentHandler.publishDeployEvent` updated to use shared `events.DeploymentEvent`
+  so the GitOps controller can unmarshal deployment lifecycle events correctly
+- `GITOPS_RECONCILE_INTERVAL` env var (default `300`s); `0` disables the periodic ticker
+- `ArtifactRoot` config field + `ARTIFACT_ROOT` env var
+

-# MASTER IMPLEMENTATION PROMPT
-## Building a Modern Git Platform with CI/CD + GitOps + Operational UX
-
-You are an elite senior staff engineer, platform architect, DevOps architect, distributed systems engineer, and product UX engineer.
-
-You are tasked with designing and implementing a next-generation self-hosted Git platform.
-
-This platform exists in the category of:
-- GitHub
-- GitLab
-- Forgejo
-- Gitea
-- Bitbucket
-
-BUT:
-
-You must NOT merely clone existing platforms.
-
-The goal is to create:
-
-> a modern developer operations platform
-
-that deeply integrates:
-- Git hosting
-- pull requests
-- CI/CD
-- GitOps
-- deployments
-- environments
-- observability
-- security
-- operational awareness
-- developer productivity
-
-The platform should feel:
-- fast
-- operational
-- developer-first
-- low cognitive load
-- modern
-- reliable
-- modular
-- keyboard-first
-- context-aware
-
-The product philosophy is:
-
-> repositories are operational systems
-
-NOT:
-
-> collections of files.
-
-==================================================
-HIGH LEVEL PRODUCT GOALS
-==================================================
-
-The platform should optimize for:
-
-- immediate situational awareness
-- workflow continuity
-- deployment visibility
-- operational clarity
-- reliability
-- developer flow
-- observability
-- intelligent automation
-- security by default
-- excellent UX
-
-Users should always be able to answer:
-
-- what changed?
-- what failed?
-- what deployed?
-- what is unhealthy?
-- what needs my attention?
-- what environments are affected?
-- what should I review next?
-- what caused this incident?
-
-without navigating deeply.
-
-==================================================
-CORE PRODUCT PRINCIPLES
-==================================================
-
-1. UX FIRST
-
-Most Git platforms prioritize functionality over usability.
-
-This platform must prioritize:
-- readability
-- discoverability
-- contextual awareness
-- progressive disclosure
-- speed
-- low noise
-- operational understanding
-
-Avoid:
-- tab overload
-- enterprise clutter
-- giant forms
-- notification spam
-- YAML-centric UX
-- log-centric UX
-
-The system should feel:
-- intentional
-- calm
-- efficient
-- operationally intelligent
-
---------------------------------------------------
-
-2. OPERATIONAL AWARENESS
-
-The platform must continuously surface:
-- failing pipelines
-- deployment health
-- environment drift
-- flaky tests
-- security issues
-- review bottlenecks
-- dependency risks
-- deployment risks
-
-This information should appear naturally throughout the UI.
-
---------------------------------------------------
-
-3. REPOSITORIES ARE RUNTIME SYSTEMS
-
-The repository page should not simply display files.
-
-It should display:
-- deployments
-- environments
-- active PRs
-- operational health
-- timelines
-- incidents
-- ownership
-- risk
-- observability
-
-The file tree is secondary.
-
---------------------------------------------------
-
-4. GITOPS IS FIRST CLASS
-
-Git should become:
-- source of truth
-- deployment history
-- environment state definition
-- rollback system
-- audit log
-
-The system must support:
-- reconciliation
-- drift detection
-- declarative environments
-- promotion workflows
-- rollback visualization
-- environment topology
-
---------------------------------------------------
-
-5. RELIABILITY IS A PRIMARY FEATURE
-
-The platform should optimize for:
-- deterministic execution
-- idempotency
-- isolation
-- resilience
-- queue durability
-- observability
-- safe rollbacks
-- fault tolerance
-
-==================================================
-ARCHITECTURE REQUIREMENTS
-==================================================
-
-Design the platform using modular services.
-
-Suggested architecture:
-
-```txt
-Platform
-├── API Gateway
-├── Auth Service
-├── Repository Service
-├── Pull Request Service
-├── Issue Service
-├── Event Bus
-├── CI Orchestrator
-├── Runner Manager
-├── Artifact Registry
-├── Package Registry
-├── Deployment Engine
-├── GitOps Controller
-├── Environment Service
-├── Secret Manager
-├── Notification Service
-├── Search Service
-├── Observability Layer
-├── Metrics Service
-├── Audit Service
-└── Web Frontend
-```
-
-==================================================
-EVENT DRIVEN ARCHITECTURE
-==================================================
-
-The platform should be event-driven.
-
-Everything emits events.
-
-Examples:
-
-```txt
-repo.created
-push.created
-pr.opened
-review.requested
-pipeline.started
-pipeline.failed
-artifact.published
-deployment.started
-deployment.failed
-environment.drift_detected
-incident.created
-```
-
-Requirements:
-- durable events
-- replay support
-- auditability
-- timeline reconstruction
-- reactive UI updates
-
-Recommended technologies:
-- NATS
-- Kafka
-- RabbitMQ
-
-Prefer NATS initially for simplicity.
-
-==================================================
-CI/CD SYSTEM REQUIREMENTS
-==================================================
-
-The CI/CD system must support:
-
-- DAG pipelines
-- matrix builds
-- reusable workflows
-- workflow templates
-- conditional execution
-- parallel execution
-- artifacts
-- caches
-- retries
-- concurrency controls
-- cancellation
-- pipeline graphs
-- environment promotion
-- rollback support
-- preview environments
-- flaky test detection
-- deployment visualization
-
-The orchestrator should:
-- schedule
-- coordinate
-- monitor
-
-NOT directly execute jobs.
-
-==================================================
-RUNNER SYSTEM REQUIREMENTS
-==================================================
-
-Runners should:
-- be ephemeral
-- isolated
-- disposable
-- reproducible
-- stateless
-
-Support execution backends:
-
-1. Docker containers
-2. Kubernetes jobs
-3. Firecracker microVMs
-4. Bare metal runners
-
-Security is critical.
-
-Forked PRs must never automatically receive secrets.
-
-==================================================
-SECRET MANAGEMENT
-==================================================
-
-Implement scoped secret management.
-
-Secret hierarchy:
-
-```txt
-Global
-→ Organization
-→ Repository
-→ Environment
-→ Runtime ephemeral injection
-```
-
-Support:
-- Vault
-- OIDC federation
-- cloud secret providers
-- encrypted secret storage
-
-Secrets must:
-- never leak to logs
-- be masked automatically
-- support audit trails
-- support rotation
-
-==================================================
-ARTIFACT + PACKAGE MANAGEMENT
-==================================================
-
-Implement:
-- build artifact storage
-- OCI registry
-- package registries
-- retention policies
-- artifact provenance
-- signing support
-- SBOM support
-
-Support:
-- container images
-- npm
-- cargo
-- pip
-- maven
-- generic artifacts
-
-==================================================
-GITOPS REQUIREMENTS
-==================================================
-
-GitOps must be deeply integrated.
-
-Support:
-- reconciliation loops
-- drift detection
-- sync visualization
-- environment topology
-- deployment promotion
-- rollback flows
-- canary releases
-- blue/green deployments
-- environment history
-
-The UI should make GitOps understandable.
-
-Avoid overwhelming Kubernetes-centric UX.
-
-==================================================
-DATABASE + STORAGE DESIGN
-==================================================
-
-Separate:
-- application code
-- repository storage
-- artifacts
-- caches
-- logs
-- uploads
-
-Repository storage should NOT exist in the app repository.
-
-Recommended:
-
-```txt
-/data/repos
-/data/artifacts
-/data/cache
-/data/uploads
-```
-
-Repository storage is runtime instance data.
-
-Treat it like:
-- database files
-- object storage
-- runtime state
-
-==================================================
-DASHBOARD REQUIREMENTS
-==================================================
-
-The dashboard should behave like:
-
-> an operational command center
-
-NOT:
-
-> a repository list.
-
-Include:
-
-1. Attention Required
-- failing pipelines
-- stale PRs
-- security alerts
-- deployment failures
-- environment drift
-
-2. Active Workspaces
-- active repos
-- active branches
-- assigned reviews
-- recent deployments
-
-3. Team Activity
-- merges
-- releases
-- deployments
-- incidents
-
-4. CI/CD Overview
-- pipeline health
-- queue health
-- flaky tests
-- deployment status
-
-5. Review Dashboard
-- pending reviews
-- high risk PRs
-- stale reviews
-
-6. Security Overview
-- dependency vulnerabilities
-- secret leaks
-- suspicious pushes
-
-==================================================
-REPOSITORY PAGE REQUIREMENTS
-==================================================
-
-The repository page must feel operational.
-
-Top area should include:
-
-```txt
-Repo Name
-Production: Healthy
-CI: Passing
-Deployments: 3 active
-Risk: Medium
-```
-
-The page should include:
-
-- active PRs
-- deployments
-- environments
-- repository health
-- security alerts
-- ownership
-- recent activity
-- operational timeline
-- preview environments
-- CI/CD overview
-- deployment history
-
-The README should not dominate the page.
-
-==================================================
-UNIFIED OPERATIONAL TIMELINE
-==================================================
-
-Implement a unified timeline merging:
-- commits
-- deployments
-- incidents
-- rollbacks
-- CI failures
-- security events
-- alerts
-- releases
-
-This is one of the most important features.
-
-Users should easily answer:
-
-> what changed before things broke?
-
-==================================================
-PIPELINE UX REQUIREMENTS
-==================================================
-
-Pipelines should be visual DAGs.
-
-Support:
-- dependency visualization
-- execution timing
-- bottleneck detection
-- retry controls
-- artifact visibility
-- live execution state
-- grouped logs
-- semantic errors
-
-Logs should support:
-- filtering
-- collapsing
-- syntax highlighting
-- structured parsing
-- AI summarization
-
-==================================================
-DEPLOYMENT UX REQUIREMENTS
-==================================================
-
-Deployments must feel first-class.
-
-Each environment should expose:
-
-```txt
-Production
-Healthy
-v1.4.2
-3 pods
-0.1% errors
-Last deploy 14m ago
-```
-
-Support:
-- rollback
-- traffic shifting
-- canary visibility
-- deployment timelines
-- release notes
-- environment logs
-- health checks
-
-==================================================
-COMMAND PALETTE REQUIREMENTS
-==================================================
-
-Implement a global command palette.
-
-Inspired by:
-- VS Code
-- Raycast
-- Linear
-
-Examples:
-
-```txt
-/retry failed jobs
-/deploy staging
-/open logs
-/review next
-/show flaky tests
-/open production incidents
-```
-
-Keyboard-first navigation is critical.
-
-==================================================
-AI-ASSISTED FEATURES
-==================================================
-
-Implement optional AI-assisted operational tooling.
-
-Examples:
-
-- failure diagnosis
-- flaky test detection
-- architecture summaries
-- impact analysis
-- deployment risk scoring
-- review summaries
-- onboarding explanations
-
-Example:
-
-```txt
-Likely failure cause:
-Database migration introduced lock contention.
-```
-
-==================================================
-OBSERVABILITY REQUIREMENTS
-==================================================
-
-Integrate:
-- metrics
-- traces
-- logs
-- deployment state
-- incident state
-- service topology
-
-Do not isolate observability into external systems.
-
-Expose operational health directly in repository pages.
-
-==================================================
-RELIABILITY REQUIREMENTS
-==================================================
-
-Implement:
-- durable queues
-- retries
-- dead-letter queues
-- resumable pipelines
-- distributed scheduling
-- concurrency controls
-- checkpointing
-- idempotent operations
-
-The platform should survive:
-- runner crashes
-- orchestrator crashes
-- network partitions
-- deployment interruptions
-
-==================================================
-SECURITY REQUIREMENTS
-==================================================
-
-Implement:
-- signed artifacts
-- provenance verification
-- branch protections
-- permission scopes
-- audit logging
-- secret scanning
-- dependency scanning
-- runner isolation
-- sandboxing
-
-Support:
-- Sigstore
-- Cosign
-- SLSA concepts
-
-==================================================
-UI/UX DESIGN LANGUAGE
-==================================================
-
-The UI should feel:
-- modern
-- minimal
-- operational
-- clean
-- responsive
-- keyboard-first
-- information dense but calm
-
-Visual inspirations:
-- Linear
-- Datadog
-- Grafana
-- Raycast
-- Arc Browser
-- VS Code
-- modern observability dashboards
-
-Avoid:
-- clutter
-- giant tables
-- excessive modal workflows
-- deeply nested navigation
-
-==================================================
-IMPLEMENTATION EXPECTATIONS
-==================================================
-
-You should:
-- think deeply about architecture
-- optimize for maintainability
-- optimize for extensibility
-- prioritize UX heavily
-- prioritize reliability heavily
-- explain tradeoffs
-- avoid overengineering early
-- support future scalability
-
-You should continuously ask:
-
-- does this reduce cognitive load?
-- does this improve operational awareness?
-- does this improve developer flow?
-- does this improve reliability?
-- does this make debugging easier?
-
-==================================================
-DELIVERABLES
-==================================================
-
-When implementing features:
-
-Provide:
-- architecture reasoning
-- schema design
-- API design
-- event definitions
-- service boundaries
-- UI mockups
-- workflow diagrams
-- UX rationale
-- security implications
-- scaling considerations
-- operational implications
-
-Always optimize for:
-- clarity
-- reliability
-- developer experience
-- operational intelligence
-- future extensibility
-
-The platform should ultimately feel like:
-
-> a unified operating system for software delivery
-
-rather than:
-
-> a Git repository viewer with CI attached.
