From 3e54d387feef40a5c07558ba9ec62bcd211ddf44 Mon Sep 17 00:00:00 2001 From: langowarny Date: Tue, 10 Mar 2026 20:24:45 +0900 Subject: [PATCH 01/52] feat: implement P2P workspace management and git bundle features - Added support for creating, joining, and managing collaborative P2P workspaces. - Introduced git bundle operations for sharing code within workspaces, including commands for initializing, pushing, and fetching git bundles. - Implemented workspace lifecycle management, including contribution tracking and chronicling of workspace activities. - Enhanced configuration options for P2P workspaces in the application settings. - Added event handling for workspace-related actions such as creation, member joining/leaving, and message posting. --- go.mod | 16 + go.sum | 41 ++

Fixed data race in Node.PubSub() by using sync.Once for lazy initialization. - Removed dead code related to chronicler wiring and git fetch subprocess in ApplyBundle. - Consolidated workspaceComponents into wsComponents for cleaner code. - Introduced typed Role constants for workspace members to enhance type safety. - Improved protocol handler efficiency by switching to a streaming JSON decoder. - Added sentinel errors for better error handling and reduced string duplication in CLI commands. -

+0900 Subject: [PATCH 05/52] feat: implement escrow hub v2, team management enhancements, app bridges - Add LangoEscrowHubV2/VaultV2 contracts with beacon proxy pattern, BeaconVaultFactory, DirectSettler and MilestoneSettler; include DeployV2/UpgradeV2 scripts and full Foundry test coverage - Add Go V2 hub client, ABI bindings, and dangling escrow detector to support the new on-chain contract architecture - Add P2P team BoltDB persistent store, split coordinator into membership and shutdown modules, and introduce team health monitor - Add app-layer bridges for team budget, reputation, shutdown, and on-chain escrow events, wiring team lifecycle to economy actions - Fix skipped simplify issues in economy escrow, onchain escrow, and p2p team payment --- .gitmodules | 3 +

Teams coordinate distributed agent work (formation, task delegation, health monitoring, disbandment), while the economy layer manages financial primitives (escrow, budget, pricing, risk). These subsystems communicate through the centralized `eventbus.Bus`. + +Before this change, the subsystems were wired in isolation: +- On-chain escrow contract events (deposit, release, dispute) were monitored by `hub.EventMonitor` and published to the bus, but nothing reacted to them. +- Team task outcomes did not affect peer reputation. +- Team disbandment or budget exhaustion did not trigger escrow settlement. +- The escrow settler only supported custodian mode (USDCSettler). + +## Goals / Non-Goals + +**Goals:** +1. Wire on-chain escrow events to the local escrow engine so the off-chain state machine stays synchronized with blockchain state. +2. Update peer reputation based on team task outcomes (success boosts, timeout penalties) and auto-kick low-reputation members. +3. Trigger graceful team shutdown when budget is exhausted, including budget warning events at the 80% threshold. +4. Support hub and vault on-chain settlement modes alongside the existing custodian mode. +5. Wire DanglingDetector to expire stuck pending escrows. + +**Non-Goals:** +1. Modifying the escrow engine state machine itself — bridges only call existing transition methods. +2. Adding new CLI commands or TUI surfaces for bridge management. +3. Changing the P2P protocol wire format. + +## Decisions + +### 1. Bridge Pattern: Event Subscription in `internal/app/` + +All bridges live in `internal/app/bridge_*.go` as thin subscriber functions. Each bridge: +- Subscribes to specific event types via `eventbus.SubscribeTyped`. +- Calls existing engine/coordinator methods to perform side effects. +- Logs at debug level for idempotent/no-op cases, warn level for real errors. + +**Rationale**: Bridges belong in the app layer because they cross subsystem boundaries (P2P <-> Economy). Placing them in `internal/app/` follows the existing pattern for `wireTeamEscrowBridge` and `wireTeamBudgetBridge`. The bridges contain no business logic — they are pure event-to-action translations. + +### 2. Idempotent Transitions for On-Chain Bridge + +The on-chain escrow bridge uses a `tryEscrowTransition` helper that catches `ErrInvalidTransition` and logs at debug level instead of warning. This makes the bridge safe for duplicate event delivery (e.g., EventMonitor replaying events after restart). + +**Rationale**: On-chain events can be replayed during block reprocessing. Without idempotency, duplicate events would flood error logs. The helper centralizes this pattern for all five event types. + +### 3. Reputation-Driven Member Eviction + +The team reputation bridge subscribes to three event types: +- `TeamMemberUnhealthyEvent` -> `RecordTimeout` -> check score -> `KickMember` if below threshold. +- `TeamTaskCompletedEvent` -> `RecordSuccess` for active workers. +- `ReputationChangedEvent` -> check score -> `KickMember` from all teams if below threshold. + +**Rationale**: A reactive approach (event-driven eviction) is simpler and more predictable than periodic polling. The configurable `minScore` threshold allows operators to tune sensitivity. + +### 4. Budget-Driven Graceful Shutdown + +The team shutdown bridge handles two thresholds: +- At 80% budget consumption: publishes `TeamBudgetWarningEvent` for UI/alerting. +- At 100% budget consumption: calls `coordinator.GracefulShutdown` which creates git bundles, settles payments, and disbands the team. + +**Rationale**: Two-stage alerting (warning then shutdown) gives operators time to react. The 80% threshold is hardcoded as a sensible default; the warning event enables downstream consumers (CLI, webhooks) to surface alerts. + +### 5. Multi-Mode Settler Selection + +`selectSettler` now dispatches on `config.Economy.Escrow.OnChain.Mode`: +- `"hub"` -> `hub.NewHubSettler` (shared escrow contract). +- `"vault"` -> `hub.NewVaultSettler` (per-deal beacon proxy vault). +- Default -> `escrow.NewUSDCSettler` (custodian mode). + +**Rationale**: Hub mode is simpler and cheaper for high-volume deals. Vault mode provides per-deal isolation for high-value transactions. Both require on-chain configuration (contract addresses). Custodian mode remains the fallback for users without on-chain infrastructure. + +## Risks / Trade-offs + +- **Event Ordering**: EventBus is synchronous and single-threaded per subscriber. If a bridge handler is slow (e.g., on-chain call), it can delay other subscribers. Mitigation: all bridge handlers perform only local state mutations or coordinator calls, not on-chain transactions. +- **Reputation Cascading**: A single bad event can cascade through multiple bridges (unhealthy -> timeout -> kick -> disband -> shutdown). Mitigation: each bridge logs its actions; the minimum score threshold acts as a circuit breaker. +- **Duplicate Event Delivery**: The on-chain bridge is designed for idempotency, but the reputation bridge is not (duplicate `RecordSuccess` calls inflate scores). Mitigation: the EventMonitor deduplicates at the source level using block number tracking. diff --git a/openspec/changes/archive/2026-03-11-app-team-economy-bridges/proposal.md b/openspec/changes/archive/2026-03-11-app-team-economy-bridges/proposal.md new file mode 100644 index 000000000..1e6fb10e2 --- /dev/null +++ b/openspec/changes/archive/2026-03-11-app-team-economy-bridges/proposal.md @@ -0,0 +1,29 @@ +# Proposal: App Bridge Layer — Team-Economy Integration + +## Why + +The P2P team lifecycle (formation, task execution, disbandment) and the economy layer (escrow, budget, reputation) were independently implemented but lacked event-driven integration.

BoltDB is already used for other P2P stores (reputation, workspace) and avoids the overhead of SQL migrations. The `TeamStore` interface allows swapping to a different backend later. + +**Alternative considered:** Ent/SQLite would provide query capabilities but adds migration complexity for data that is primarily accessed by ID. Teams are short-lived (minutes to hours), not long-lived records. + +### Interface-based store design +The `TeamStore` interface (Save/Load/LoadAll/Delete) decouples the coordinator from the storage backend. This enables in-memory stores for testing and alternative backends without modifying coordination logic. + +### HealthMonitor as lifecycle.Component +The health monitor runs a periodic goroutine and needs clean startup/shutdown. Implementing `lifecycle.Component` (Name/Start/Stop) integrates it with the existing lifecycle registry for ordered startup and graceful shutdown. + +**Alternative considered:** Using a cron job for health checks. Rejected because the health monitor needs persistent counter state and event subscriptions that don't map cleanly to the cron model. + +### Event-driven counter reset +Instead of querying the coordinator for task completion status, the health monitor subscribes to `TeamTaskCompletedEvent` via the EventBus. This avoids coupling and reuses the existing event pattern. Similarly, `TeamDisbandedEvent` triggers cleanup of tracking maps to prevent memory leaks. + +### StatusShuttingDown as explicit state +Adding a `StatusShuttingDown` team state (between Active and Disbanded) enables `DelegateTask` to reject new work during graceful shutdown. This is simpler than a separate shutdown flag and integrates cleanly with existing state checks. + +### Members serialized as slice in JSON +The internal `map[string]*Member` is serialized as a JSON array via custom `MarshalJSON`/`UnmarshalJSON`. This produces cleaner JSON output and is straightforward to reconstruct into the map on deserialization. + +## Risks / Trade-offs + +- **[Risk] BoltDB single-writer bottleneck** -> Team operations are infrequent (formation/disbanding) so write contention is negligible. Read-heavy operations (GetTeam, ListTeams) use the in-memory map, not the store. +- **[Risk] Health ping false positives under network partitions** -> The maxMissed threshold (default 3) with 30s intervals gives 90 seconds before unhealthy detection, providing tolerance for transient network issues. +- **[Risk] Memory growth from tracking maps** -> The `TeamDisbandedEvent` subscription in HealthMonitor cleans up miss counts and lastSeen maps when teams end. Active teams are bounded by operational use. +- **[Trade-off] No auto-kick on unhealthy** -> Publishing `TeamMemberUnhealthyEvent` rather than auto-removing gives the bridge layer control over the response (e.g., retry, degrade, or kick).

langowarny Date: Wed, 11 Mar 2026 23:01:22 +0900 Subject: [PATCH 07/52] feat: add confirmation depth and reorg detection to on-chain escrow - Introduced a new `ConfirmationDepth` configuration option for the on-chain escrow, allowing users to specify the number of blocks to wait before processing events to protect against L2 reorgs. - Implemented reorg detection in the event monitor, publishing `EscrowReorgDetectedEvent` when a reorganization is detected, with appropriate logging for deep and shallow reorgs. - Updated CLI commands and documentation to reflect the new confirmation depth feature and its implications for event processing. --- internal/app/bridge_onchain_escrow.go | 13 ++ internal/app/wiring_economy.go | 5 + internal/cli/economy/escrow.go | 1 +

Added a `timeout` parameter to cron job definitions, allowing for per-job execution time limits. - Enhanced the `AddJob` method to return the persisted job from the `Upsert` operation, reducing unnecessary database calls. - Updated the scheduler to handle job timeouts and ensure proper context management during execution. - Refactored the `Stop` method in the scheduler to prevent double-close panics using `sync.Once`. -

per workspace. Currently, `CreateBundle` always bundles all refs (`--all`), and `ApplyBundle` directly unbundles without verification or rollback. When multiple agents push to the same branch, conflicts arise with no resolution path. + +Bare repos lack a working tree, so standard `git merge` is unavailable. Git 2.38+ introduced `merge-tree --write-tree` which performs 3-way merge producing a tree object, enabling merges without checkout. + +## Goals / Non-Goals + +**Goals:** +- Reduce bundle sizes by 90%+ for incremental syncs between agents with shared history +- Enable safe bundle application with verification and atomic rollback on failure +- Isolate agent work via per-task branches to eliminate concurrent modification conflicts +- Detect git state divergence across team members via health monitoring +- Provide structured conflict reports when merges fail + +**Non-Goals:** +- Automatic conflict resolution (agents cannot meaningfully resolve code conflicts) +- File-level locking via economy system (excessive complexity) +- Custom merge strategies beyond Git's default recursive +- Working-tree operations (all operations target bare repos) + +## Decisions + +### 1. Incremental Bundles via `base..HEAD` Range +**Decision**: Use git's native range syntax for incremental bundles with automatic fallback to full bundles. +**Rationale**: Git bundle format natively supports commit ranges. The fallback ensures reliability when the base commit is missing (e.g., after repo compaction or first sync). +**Alternative considered**: Delta compression at application level — rejected because git's built-in range support is simpler and battle-tested. + +### 2. Ref Snapshot/Restore for Transactional Apply +**Decision**: Capture all refs via `git for-each-ref` before applying, restore via `git update-ref` on failure. +**Rationale**: Bare repos don't support `git stash`. Ref snapshots provide equivalent rollback capability with minimal overhead. +**Alternative considered**: Copy entire .git directory — rejected due to I/O cost for large repos. + +### 3. `git merge-tree --write-tree` for Bare-Repo Merge +**Decision**: Use merge-tree + commit-tree + update-ref pipeline for merging branches in bare repos. +**Rationale**: This is the only way to perform 3-way merges without a working tree. Available in Git 2.38+ which is widely deployed. +**Alternative considered**: Temporary working tree checkout — rejected because it requires disk space and cleanup, and is not safe for concurrent operations. + +### 4. Branch-Per-Task Isolation +**Decision**: Each agent task gets a `task/{taskID}` branch, merged into target when complete. +**Rationale**: Eliminates conflicts at the source. Agents work independently; conflicts only surface at merge time when they can be reported structurally. +**Alternative considered**: File locking via economy tokens — rejected as overly complex with poor ergonomics. + +### 5. Health Monitor Git State via Ping Extension +**Decision**: Extend health ping responses to include HEAD hashes, with majority-vote divergence detection. +**Rationale**: Lightweight addition to existing health check infrastructure. Divergence detection identifies sync issues without additional protocol messages. + +## Risks / Trade-offs + +- **[Git 2.38+ dependency]** → `merge-tree --write-tree` requires Git 2.38+. Mitigated by graceful error handling; branch operations still work, only merge is affected. +- **[Incremental bundle prerequisite miss]** → Remote may not have the base commit. Mitigated by `VerifyBundle` check and automatic fallback to full bundle. +- **[Ref snapshot size]** → Repos with many refs could have large snapshots. Mitigated by ref count being typically small (tens, not thousands) in workspace repos. +- **[Merge-tree false conflicts]** → Git may report conflicts that could be auto-resolved with more context.

Extract runGit() helper to eliminate repeated exec/stdout/stderr boilerplate p2p/handshake: - Add SessionStore.GetByToken() for direct token lookup instead of iterating ActiveSessions() in callers p2p/team/health_monitor: - Guard event subscriptions with sync.Once to prevent duplicate registrations on repeated Start() calls - Use dedicated context variables (pingCtx, gsCtx) for ping and git-state calls so each gets its own independent timeout budget economy/escrow: - Add ListByStatusBefore(status, before) to Store interface, memoryStore, and EntStore to push time-window filtering into the query layer - Update DanglingDetector.scan() to use the new method, removing per-entry time checks in application code cron: - Replace positional New() parameters with SchedulerConfig struct for safer, self-documenting construction; apply nil/zero defaults inside New() app: - Consolidate floatToUSDC / floatToBudgetAmount duplicates into a single floatToMicroUSDC() in convert.go - Use SessionStore.GetByToken() in session validator closure - Add context timeout for identity.DID() call on startup - Pre-allocate member slices with known capacity in team tool handlers --- internal/app/app.go | 11 ++--- internal/app/bridge_team_budget.go | 8 +--- internal/app/bridge_team_escrow.go | 8 +--- internal/app/convert.go | 9 ++++ internal/app/tools_team.go | 10 +++-- internal/app/wiring_automation.go | 7 ++- internal/cron/scheduler.go | 35 ++++++++++----- internal/cron/scheduler_test.go | 41 ++++++++++++++--- internal/economy/escrow/ent_store.go | 26 +++++++++++ .../economy/escrow/hub/dangling_detector.go | 6 +-- internal/economy/escrow/store.go | 14 ++++++ internal/p2p/gitbundle/bundle.go | 42 ++++++++---------- internal/p2p/handshake/session.go | 13 ++++++ internal/p2p/team/health_monitor.go | 32 ++++++++------ .../.openspec.yaml | 2 + .../design.md | 42 ++++++++++++++++++ .../proposal.md | 44 +++++++++++++++++++ .../specs/cron-scheduling/spec.md | 12 +++++ .../specs/economy-escrow/spec.md | 16 +++++++ .../specs/team-health-monitoring/spec.md | 39 ++++++++++++++++ .../tasks.md | 39 ++++++++++++++++ openspec/specs/cron-scheduling/spec.md | 12 +++++ openspec/specs/economy-escrow/spec.md | 16 +++++++ openspec/specs/team-health-monitoring/spec.md | 8 ++++ 24 files changed, 407 insertions(+), 85 deletions(-) create mode 100644 internal/app/convert.go create mode 100644 openspec/changes/archive/2026-03-12-code-review-git-bundle-enhancement/.openspec.yaml create mode 100644 openspec/changes/archive/2026-03-12-code-review-git-bundle-enhancement/design.md create mode 100644 openspec/changes/archive/2026-03-12-code-review-git-bundle-enhancement/proposal.md create mode 100644 openspec/changes/archive/2026-03-12-code-review-git-bundle-enhancement/specs/cron-scheduling/spec.md create mode 100644 openspec/changes/archive/2026-03-12-code-review-git-bundle-enhancement/specs/economy-escrow/spec.md create mode 100644 openspec/changes/archive/2026-03-12-code-review-git-bundle-enhancement/specs/team-health-monitoring/spec.md create mode 100644 openspec/changes/archive/2026-03-12-code-review-git-bundle-enhancement/tasks.md diff --git a/internal/app/app.go b/internal/app/app.go index 83bbc616e..90706c99e 100644 --- a/internal/app/app.go +++ b/internal/app/app.go @@ -309,18 +309,15 @@ func New(boot *bootstrap.Result) (*App, error) { if p2pc.sessions != nil { sess := p2pc.sessions sessionValidator = func(token string) (string, bool) { -

If ping consumed most of the timeout, git state calls would starve. Decision: create a second independent 10s context for git state after successful ping. Alternative: single longer timeout — rejected because it delays unhealthy detection. + +2. **sync.Once for event subscriptions** — Each `Start()` call registered new event bus subscriptions without cleanup. Decision: use `sync.Once` to register subscriptions exactly once regardless of restart cycles. Alternative: unsubscribe in `Stop()` — rejected because eventbus doesn't expose unsubscribe API. + +3. **GetByToken on SessionStore** — The session validator iterated `ActiveSessions()` per request. Decision: add `GetByToken()` method that does the linear scan internally (sessions are keyed by peerDID, not token, so a reverse index would need maintenance). For the typical small N (handful of peers), this is sufficient. Alternative: maintain a token→DID reverse map — rejected as premature optimization for small N. + +4. **SchedulerConfig struct** — 6 positional params is error-prone. Decision: keep `store` and `executor` positional (required), move `timezone`, `maxJobs`, `defaultTimeout`, `logger` into a config struct with sensible defaults. This follows the project's functional options pattern. + +5. **ListByStatusBefore on escrow Store** — DanglingDetector loaded ALL pending escrows every scan interval. Decision: add a `ListByStatusBefore(status, time.Time)` method to filter at the DB level. The ent ORM already generates `CreatedAtLT` predicates, so the implementation is straightforward. + +6. **Shared floatToMicroUSDC** — Two identical functions (`floatToBudgetAmount`, `floatToUSDC`) in separate bridge files. Decision: extract to `internal/app/convert.go` as `floatToMicroUSDC`. The original comment "kept separate to avoid coupling" was misguided — they're in the same package. + +7. **runGit helper** — The same `exec.CommandContext` + stdout/stderr buffer pattern repeated 3+ times in `bundle.go`. Decision: extract a package-private `runGit(ctx, repoPath, args...)` helper. The `CreateBundle` and `CreateIncrementalBundle` methods keep their own buffer handling due to needing raw bytes + custom error detection. + +## Risks / Trade-offs + +- **Store interface change** → All `escrow.Store` implementations must add `ListByStatusBefore`. Both in-tree implementations (memoryStore, EntStore) are updated. Risk: external implementations would break. Mitigation: this is an internal interface with no known external consumers. +- **Cron constructor API change** → All callers of `cron.New()` must update. Risk: missed callers. Mitigation: `go build ./...` catches all at compile time; tests updated. +- **runGit error format change** → `Diff` and `snapshotRefs` now use `runGit`'s error format (`git : : `) instead of their previous format. Risk: error message parsing in tests.

Updated command groups in the CLI for better user intent alignment, introducing categories like "Getting Started," "AI & Knowledge," "Automation," and "Network & Economy." - Added a new `lango status` command to provide a unified system status dashboard, displaying health, configuration, and feature status. - Introduced preset profiles for onboarding, allowing users to start with purpose-built configurations (minimal, researcher, collaborator, full). - Enhanced the onboarding command to accept a `--preset` flag, guiding users through setup with relevant feature recommendations. - Implemented tier-based visibility in the settings menu, reducing cognitive load by categorizing options into Basic and Advanced tiers. - Added a startup summary to display activated features immediately after `lango serve` starts. --- cmd/lango/main.go | 249 ++++++++++++------ internal/cli/onboard/onboard.go | 103 ++++++-- internal/cli/settings/menu.go | 188 ++++++++----- internal/cli/settings/settings.go | 26 +- internal/cli/status/render.go | 93 +++++++ internal/cli/status/status.go | 163 ++++++++++++ internal/cli/status/status_test.go | 212 +++++++++++++++ internal/cli/tui/banner.go | 39 +++ internal/config/presets.go | 81 ++++++ internal/config/presets_test.go | 98 +++++++ .../2026-03-12-ux-simplify/.openspec.yaml | 2 + .../archive/2026-03-12-ux-simplify/design.md | 42 +++ .../2026-03-12-ux-simplify/proposal.md | 37 +++ .../specs/brand-banner/spec.md | 19 ++ .../specs/cli-command-groups/spec.md | 24 ++ .../specs/cli-onboard/spec.md | 30 +++ .../specs/cli-settings/spec.md | 20 ++ .../specs/cli-status-dashboard/spec.md | 34 +++ .../specs/config-presets/spec.md | 42 +++ .../specs/settings-tier-system/spec.md | 30 +++ .../archive/2026-03-12-ux-simplify/tasks.md | 50 ++++ openspec/specs/brand-banner/spec.md | 18 ++ openspec/specs/cli-command-groups/spec.md | 31 ++- openspec/specs/cli-onboard/spec.md | 29 ++ openspec/specs/cli-settings/spec.md | 18 +- openspec/specs/cli-status-dashboard/spec.md | 38 +++ openspec/specs/config-presets/spec.md | 46 ++++ openspec/specs/settings-tier-system/spec.md | 34 +++ 28 files changed, 1604 insertions(+), 192 deletions(-) create mode 100644 internal/cli/status/render.go create mode 100644 internal/cli/status/status.go create mode 100644 internal/cli/status/status_test.go create mode 100644 internal/config/presets.go create mode 100644 internal/config/presets_test.go create mode 100644 openspec/changes/archive/2026-03-12-ux-simplify/.openspec.yaml create mode 100644 openspec/changes/archive/2026-03-12-ux-simplify/design.md create mode 100644 openspec/changes/archive/2026-03-12-ux-simplify/proposal.md create mode 100644 openspec/changes/archive/2026-03-12-ux-simplify/specs/brand-banner/spec.md create mode 100644 openspec/changes/archive/2026-03-12-ux-simplify/specs/cli-command-groups/spec.md create mode 100644 openspec/changes/archive/2026-03-12-ux-simplify/specs/cli-onboard/spec.md create mode 100644 openspec/changes/archive/2026-03-12-ux-simplify/specs/cli-settings/spec.md create mode 100644 openspec/changes/archive/2026-03-12-ux-simplify/specs/cli-status-dashboard/spec.md create mode 100644 openspec/changes/archive/2026-03-12-ux-simplify/specs/config-presets/spec.md create mode 100644 openspec/changes/archive/2026-03-12-ux-simplify/specs/settings-tier-system/spec.md create mode 100644 openspec/changes/archive/2026-03-12-ux-simplify/tasks.md create mode 100644 openspec/specs/cli-status-dashboard/spec.md create mode 100644 openspec/specs/config-presets/spec.md create mode 100644 openspec/specs/settings-tier-system/spec.md diff --git a/cmd/lango/main.go b/cmd/lango/main.go index ab9352208..624638e52 100644 --- a/cmd/lango/main.go +++ b/cmd/lango/main.go @@ -8,6 +8,7 @@ import ( "os" "os/signal" "strconv" + "strings" "syscall" "text/tabwriter" "time" @@ -37,6 +38,7 @@ import ( clisecurity "github.com/langoai/lango/internal/cli/security" "github.com/langoai/lango/internal/cli/settings" cliaccount "github.com/langoai/lango/internal/cli/smartaccount" + clistatus "github.com/langoai/lango/internal/cli/status" "github.com/langoai/lango/internal/cli/tui" cliworkflow "github.com/langoai/lango/internal/cli/workflow" "github.com/langoai/lango/internal/config" @@ -70,35 +72,45 @@ func main() { } rootCmd.AddGroup( -

If the base commit is not found in the repository, it falls back to a full bundle automatically. + +Before applying a received bundle, `VerifyBundle` checks that the bundle's prerequisite commits exist in the local repo. `SafeApplyBundle` combines verification, ref snapshot, application, and automatic rollback on failure into a single atomic operation: + +1. **Verify** — check prerequisites are present +2. **Snapshot** — capture current ref state +3. **Apply** — unbundle into the repository +4. **Rollback** — if apply fails, restore refs from the snapshot + +`HasCommit` checks whether a specific commit exists locally, which is useful for determining the correct base commit before requesting an incremental bundle from a peer. + +--- + +### lango p2p git branch + +Manage task branches within a workspace repository.

Three-Layer Architecture +**Decision**: Implement prevention (prompt), upstream (truncation), and downstream (sanitization) as independent layers. +**Rationale**: Defense-in-depth. Each layer catches what the others miss. Prompt instructs the model; truncation reduces noise before model sees it; sanitizer catches anything that still leaks through. +**Alternative**: Single post-processing sanitizer only — rejected because large tool outputs would still confuse the model even if cleaned from the response. + +### 2. Middleware Pattern for Truncation +**Decision**: Implement truncation as a `toolchain.Middleware` using the existing `Chain/ChainAll` pattern. +**Rationale**: Zero new abstractions needed. Consistent with `WithLearning`, `WithHooks`, `WithApproval`. Applied to all tools uniformly via `ChainAll`. +**Alternative**: Truncation inside the ADK adapter — rejected because it would couple truncation logic to ADK internals. + +### 3. Code Block Protection in Sanitizer +**Decision**: Use placeholder-based protection to preserve code blocks during thought tag stripping. +**Rationale**: Simple and effective. Code blocks are extracted, placeholders inserted, tags stripped, then code blocks restored. Avoids complex negative lookahead regex. +**Alternative**: Single regex with negative lookahead — rejected due to complexity and fragility with nested content. + +### 4. `*bool` Pointer Config Pattern +**Decision**: Use `*bool` pointers for feature toggles (nil = enabled by default). +**Rationale**: Follows established pattern (`AgentConfig.ErrorCorrectionEnabled`). Users can explicitly disable features without needing to set all defaults. + +### 5. Truncation Before Hooks +**Decision**: Place truncation middleware (step 7a) before hooks middleware (step 7b) in the wiring pipeline. +**Rationale**: Truncated output flows to hooks, not the other way around. Hooks (security filter, event publishing) should see the same output the model will see. + +## Risks / Trade-offs + +- **[False positive stripping]** → Code block protection prevents stripping tags inside code blocks. Marker stripping uses line-start anchoring to minimize false matches. +- **[Truncation data loss]** → Marker `"\n... [output truncated]"` tells the model that data was cut. Default 8000 chars is generous (~2000 tokens). +- **[Chunk sanitization limitations]** → Current implementation applies full `Sanitize()` per chunk, which may miss tags spanning multiple chunks. Accepted trade-off for v1; stateful `ChunkSanitizer` is a future enhancement. +- **[Config complexity]** → Six toggle fields may seem like many, but `*bool` nil-defaults mean zero-config works out of the box.

From e59eec7c825ff2312a346138bfe833b9c3fde162 Mon Sep 17 00:00:00 2001 From: langowarny Date: Sat, 14 Mar 2026 06:50:28 +0900 Subject: [PATCH 16/52] refactor: streamline parameter handling across tools using toolparam - Replaced manual parameter extraction with `toolparam` utility functions for improved error handling and code clarity. - Updated various tool handlers to utilize `RequireString`, `OptionalString`, `OptionalInt`, and `StringSlice` methods for parameter validation and extraction. - Enhanced consistency in parameter management across multiple tools, including cron, browser, contract, data, economy, escrow, and more. - Improved overall code maintainability and readability by reducing repetitive code patterns. --- internal/app/tools_automation.go | 119 +++++----- internal/app/tools_browser.go | 48 ++-- internal/app/tools_contract.go | 37 +-- internal/app/tools_data.go | 73 ++---- internal/app/tools_economy.go | 86 +++---- internal/app/tools_escrow.go | 89 +++++--- internal/app/tools_meta.go | 87 +++---- internal/app/tools_p2p.go | 107 ++++----- internal/app/tools_sentinel.go | 16 +- internal/app/tools_smartaccount.go | 65 +++--- internal/app/tools_team.go | 48 ++-- internal/app/tools_workspace.go | 105 +++++---- internal/cli/workflow/errors.go | 5 + internal/cli/workflow/workflow.go | 8 +- internal/config/constants.go | 12 + internal/config/loader.go | 24 +- internal/economy/escrow/ent_store.go | 10 +- internal/economy/escrow/ent_store_test.go | 10 +- internal/economy/escrow/errors.go | 8 + internal/economy/escrow/hub/client.go | 129 ++++------- internal/economy/escrow/hub/client_test.go | 4 +- internal/economy/escrow/hub/client_v2.go | 145 ++++-------- internal/economy/escrow/hub/methods.go | 23 ++ internal/economy/escrow/sentinel/detector.go | 129 +++++------ internal/economy/escrow/sentinel/types.go | 29 ++- internal/economy/escrow/types.go | 9 + internal/p2p/workspace/errors.go | 7 + internal/p2p/workspace/manager.go | 16 +- internal/toolparam/extract.go | 62 +++++ internal/toolparam/extract_test.go | 212 ++++++++++++++++++ internal/toolparam/response.go | 18 ++ .../.openspec.yaml | 2 + .../design.md | 43 ++++ .../proposal.md | 33 +++ .../specs/config-system/spec.md | 12 + .../specs/economy-escrow/spec.md | 32 +++ .../specs/sentinel-errors/spec.md | 46 ++++ .../specs/toolparam-extraction/spec.md | 67 ++++++ .../tasks.md | 45 ++++ openspec/specs/config-system/spec.md | 10 +- openspec/specs/economy-escrow/spec.md | 29 +++ openspec/specs/sentinel-errors/spec.md | 43 ++++ openspec/specs/toolparam-extraction/spec.md | 71 ++++++ 43 files changed, 1430 insertions(+), 743 deletions(-) create mode 100644 internal/cli/workflow/errors.go create mode 100644 internal/config/constants.go create mode 100644 internal/economy/escrow/errors.go create mode 100644 internal/economy/escrow/hub/methods.go create mode 100644 internal/p2p/workspace/errors.go create mode 100644 internal/toolparam/extract.go create mode 100644 internal/toolparam/extract_test.go create mode 100644 internal/toolparam/response.go create mode 100644 openspec/changes/archive/2026-03-14-refactor-v020-code-quality/.openspec.yaml create mode 100644 openspec/changes/archive/2026-03-14-refactor-v020-code-quality/design.md create mode 100644 openspec/changes/archive/2026-03-14-refactor-v020-code-quality/proposal.md create mode 100644 openspec/changes/archive/2026-03-14-refactor-v020-code-quality/specs/config-system/spec.md create mode 100644 openspec/changes/archive/2026-03-14-refactor-v020-code-quality/specs/economy-escrow/spec.md create mode 100644 openspec/changes/archive/2026-03-14-refactor-v020-code-quality/specs/sentinel-errors/spec.md create mode 100644 openspec/changes/archive/2026-03-14-refactor-v020-code-quality/specs/toolparam-extraction/spec.md create mode 100644 openspec/changes/archive/2026-03-14-refactor-v020-code-quality/tasks.md create mode 100644 openspec/specs/toolparam-extraction/spec.md diff --git a/internal/app/tools_automation.go b/internal/app/tools_automation.go index 690e10d67..46ec19b97 100644 --- a/internal/app/tools_automation.go +++ b/internal/app/tools_automation.go @@ -11,6 +11,7 @@ import ( "github.com/langoai/lango/internal/background" cronpkg "github.com/langoai/lango/internal/cron" "github.com/langoai/lango/internal/session" + "github.com/langoai/lango/internal/toolparam" "github.com/langoai/lango/internal/workflow" ) @@ -35,27 +36,25 @@ func buildCronTools(scheduler *cronpkg.Scheduler, defaultDeliverTo []string) []* "required": []string{"name", "schedule_type", "schedule", "prompt"}, }, Handler: func(ctx context.Context, params map[string]interface{}) (interface{}, error) { -

feat: exec tool security hardening & data root enforcement - Add CommandGuard (internal/tools/exec/guard.go) to block commands accessing protected data paths (~/.lango/) and process management commands (kill, pkill, killall) via the exec/exec_bg tools - Add DefaultBlockedPatterns to SecurityFilterHook with catastrophic command patterns (rm -rf /, mkfs, dd, fork bomb) always active - Make SecurityFilterHook registration unconditional (not gated by config flags) so security baseline cannot be disabled - Add DataRoot config field with path validation enforcing all data paths (DB, graph, skills, workflows, P2P keys) reside under it - Add NormalizePaths/ValidateDataPaths to config loader pipeline - Add AdditionalProtectedPaths to ExecToolConfig for user-specified extra protected paths beyond DataRoot - Define BlockedResult struct replacing map[string]interface{} for typed tool handler responses - Pre-lowercase security filter patterns at construction time and pre-build strings.Replacer for command normalization hot path --- internal/app/app.go | 24 ++- internal/app/tools.go | 19 +- internal/app/tools_exec.go | 20 +- internal/app/tools_test.go | 32 +++

It receives protected paths at construction time and resolves them to absolute form. The guard uses substring matching on the normalized command string rather than full shell parsing. + +**Alternative considered:** Integrating guard logic directly into SecurityFilterHook. Rejected because the hook operates on pattern matching (generic substrings) while the guard needs path resolution and verb extraction (domain-specific). + +### Decision 2: Pre-built strings.Replacer for command normalization +The guard pre-builds a `strings.Replacer` at construction time for `$HOME`, `${HOME}`, and tilde-at-word-boundary replacements. This avoids repeated string allocations on every exec invocation. + +### Decision 3: SecurityFilterHook always active +The hook registration is moved out of the `cfg.Hooks.Enabled` conditional block. Default patterns are merged with user patterns at construction time, with case-insensitive deduplication. Patterns are pre-lowercased at construction for O(1) matching in the hot path. + +### Decision 4: DataRoot with path normalization pipeline +A `DataRoot` field in Config (default `~/.lango/`) serves as the single root for all data paths. `NormalizePaths()` expands tildes and resolves relative paths under DataRoot. `ValidateDataPaths()` verifies all paths are under the root. Both run in the Load pipeline before Validate. + +### Decision 5: BlockedResult struct +Replace `map[string]interface{}{"blocked": true, "message": msg}` with `BlockedResult{Blocked: true, Message: msg}` for type safety. The handler return type is `interface{}`, so the struct is fully compatible. + +## Risks / Trade-offs + +- **Heuristic matching** — Substring matching can have false positives (e.g., a file named `~/.lango-backup/` would be blocked). Mitigation: protected paths are resolved to absolute form, reducing ambiguity. +- **Shell escaping bypass** — A sophisticated command could encode paths to bypass string matching (e.g., hex-encoded). Mitigation: this guard is a defense-in-depth layer; the approval flow still applies to all dangerous tools. +- **DataRoot flexibility** — Users can change DataRoot (e.g., for Docker), but all sub-paths must stay under it.

Three-tier classification (Small/Medium/Large) +Tiers are based on token count relative to budget: Small (≤budget), Medium (≤3×budget), Large (>3×budget). Each tier gets progressively more aggressive compression. **Why**: A single threshold creates a jarring cliff; three tiers provide graceful degradation. + +### 2. Content-aware compression via `tooloutput.Compress()` +The middleware detects content type and delegates to type-specific compressors (CompressJSON, CompressLog, CompressCode, CompressStackTrace, CompressHeadTail). **Why**: Generic head/tail compression destroys structure in JSON arrays and loses critical ERROR lines in logs. Type-specific strategies preserve the most relevant information. + +### 3. `_meta` injection as top-level field (not envelope wrapping) +Original string results become `{"content": "...", "_meta": {...}}`. Map results get `_meta` injected directly. **Why**: Envelope wrapping would break P2P executor compatibility. Top-level injection keeps the result shape predictable. + +### 4. `OutputStorer` interface for store injection +The middleware accepts an optional `OutputStorer` interface rather than a concrete `*OutputStore`. **Why**: Testability (mock store in tests) and decoupling (middleware doesn't import lifecycle concerns). + +### 5. In-memory TTL store with lifecycle.Component +`OutputStore` uses a sync.RWMutex map with background cleanup every TTL/2. Implements `lifecycle.Component` for graceful startup/shutdown. **Why**: Simple, no external dependencies. 10-minute TTL is sufficient since agents act on results immediately. The lifecycle pattern ensures the cleanup goroutine is properly managed. + +### 6. `fs_stat` + offset/limit as source-side prevention +Rather than only compressing at the output, smart reading prevents large outputs from being generated. `fs_stat` lets the agent check file size before reading; `offset/limit` enables paginated reading. **Why**: Prevention is cheaper than compression. + +## Risks / Trade-offs + +- [Token estimation is approximate] → Acceptable for budget-based decisions; exact tokenization would require model-specific tokenizers and add latency. +- [In-memory store loses data on restart] → Acceptable; tool outputs are ephemeral and can be re-generated. No persistence needed. +- [Content detection may misclassify] → Falls back to generic CompressHeadTail which is always safe.

From 66d36becbcc94bbd129c5bf6b75cd45999b1c3d5 Mon Sep 17 00:00:00 2001 From: langowarny Date: Sat, 14 Mar 2026 15:30:49 +0900 Subject: [PATCH 19/52] fix: enhance on-chain transaction handling and gas fee management - Implemented receipt status validation in `caller.Write()` to return errors on transaction reverts and timeouts. - Updated bundler client to retrieve nonce using `EntryPoint.getNonce()` via `eth_call` instead of `eth_getTransactionCount`. - Introduced `GetGasFees()` method to fetch EIP-1559 gas fee parameters, ensuring UserOps have correct gas prices. - Improved deployment detection in `IsDeployed()` using `ethclient.CodeAt()` for reliable on-chain verification. - Added post-deploy verification in `GetOrDeploy()` to confirm contract existence after deployment. - Fixed UserOp signing to use `SignTransaction()` to avoid double-hashing issues. --- internal/app/wiring_smartaccount.go | 1 + internal/cli/smartaccount/deps.go | 1 + internal/contract/caller.go | 20 +++- internal/smartaccount/bundler/client.go | 110 ++++++++++++++++-- internal/smartaccount/bundler/types.go | 6 + internal/smartaccount/factory.go | 48 +++----- internal/smartaccount/factory_test.go | 48 +++----- internal/smartaccount/integration_test.go | 16 ++- internal/smartaccount/manager.go | 29 ++++- internal/smartaccount/manager_test.go | 87 ++++++++++++-- .../.openspec.yaml | 2 + .../2026-03-14-fix-onchain-bugs/design.md | 59 ++++++++++ .../2026-03-14-fix-onchain-bugs/proposal.md | 35 ++++++ .../specs/contract-interaction/spec.md | 16 +++ .../specs/smart-account/spec.md | 52 +++++++++ .../2026-03-14-fix-onchain-bugs/tasks.md | 43 +++++++ openspec/specs/contract-interaction/spec.md | 10 +- openspec/specs/smart-account/spec.md | 6 +- 18 files changed, 494 insertions(+), 95 deletions(-) create mode 100644 openspec/changes/archive/2026-03-14-fix-onchain-bugs/.openspec.yaml create mode 100644 openspec/changes/archive/2026-03-14-fix-onchain-bugs/design.md create mode 100644 openspec/changes/archive/2026-03-14-fix-onchain-bugs/proposal.md create mode 100644 openspec/changes/archive/2026-03-14-fix-onchain-bugs/specs/contract-interaction/spec.md create mode 100644 openspec/changes/archive/2026-03-14-fix-onchain-bugs/specs/smart-account/spec.md create mode 100644 openspec/changes/archive/2026-03-14-fix-onchain-bugs/tasks.md diff --git a/internal/app/wiring_smartaccount.go b/internal/app/wiring_smartaccount.go index f8239a5a0..8738e5076 100644 --- a/internal/app/wiring_smartaccount.go +++ b/internal/app/wiring_smartaccount.go @@ -128,6 +128,7 @@ func initSmartAccount( caller := contract.NewCaller(pc.rpcClient, pc.wallet, pc.chainID, abiCache) factory := sa.NewFactory( caller, + pc.rpcClient, common.HexToAddress(cfg.SmartAccount.FactoryAddress), common.HexToAddress(cfg.SmartAccount.Safe7579Address), common.HexToAddress(cfg.SmartAccount.FallbackHandler), diff --git a/internal/cli/smartaccount/deps.go b/internal/cli/smartaccount/deps.go index 2beaa5aae..46bf2142e 100644 --- a/internal/cli/smartaccount/deps.go +++ b/internal/cli/smartaccount/deps.go @@ -110,6 +110,7 @@ func initSmartAccountDeps(boot *bootstrap.Result) (*smartAccountDeps, error) { caller := contract.NewCaller(rpcClient, wp, chainID, abiCache) factory := sa.NewFactory( caller, + rpcClient, common.HexToAddress(cfg.SmartAccount.FactoryAddress), common.HexToAddress(cfg.SmartAccount.Safe7579Address), common.HexToAddress(cfg.SmartAccount.FallbackHandler), diff --git a/internal/contract/caller.go b/internal/contract/caller.go index da371d6b2..b45a7bbb4 100644 --- a/internal/contract/caller.go +++ b/internal/contract/caller.go @@ -2,6 +2,7 @@ package contract import ( "context" + "errors" "fmt" "math/big" "sync" @@ -16,6 +17,12 @@ import ( "github.com/langoai/lango/internal/wallet" ) +// Sentinel errors for contract call operations. +var ( + ErrTxReverted = errors.New("transaction reverted") + ErrReceiptTimeout = errors.New("receipt timeout") +) + // DefaultTimeout is the default context timeout for contract calls. const DefaultTimeout = 30 * time.Second @@ -191,9 +198,14 @@ func (c *Caller) Write(ctx context.Context, req ContractCallRequest) (*ContractC // Wait for receipt. receipt, err := c.waitForReceipt(ctx, signedTx.Hash()) if err != nil { -

This balances responsiveness with RPC rate limiting. + +### D3: SignTransaction for pre-hashed digests +`SignTransaction` signs raw bytes; `SignMessage` applies keccak256 first. EIP-712 typed data and ERC-4337 UserOp hashes are already keccak256 digests, so `SignTransaction` is the correct method.

Mitigated by caching after first successful call. +- **[Risk] WalletSigner interface change** → Adding `SignTransaction` is additive (not breaking) since all existing wallet implementations already have this method from the `WalletProvider` interface. +- **[Trade-off] Per-service mutex limits throughput** → Concurrent transactions from the same service are serialized.

23:32:20 +0900 Subject: [PATCH 23/52] feat: add integration tests for P2P discovery, handshake, and escrow functionality - Introduced Docker Compose configurations for P2P discovery and handshake tests with two agents (Alice and Bob). - Added scripts for health checks, discovery tests, and escrow contract interactions. - Implemented Makefile for easy setup, testing, and cleanup of the integration environment. - Created README documentation detailing architecture, configuration, and test scenarios for the new examples. - Included necessary secrets and entrypoint scripts for agent initialization and configuration management. --- examples/discovery-and-handshake/Makefile | 32 +++ examples/discovery-and-handshake/README.md | 103 +++++++++ .../docker-compose.yml | 60 +++++

feat: implement adaptive idle timeout mechanism - Introduced IdleTimeout configuration to allow requests to remain active during agent activity, preventing premature timeouts. - Added ErrIdleTimeout error code for specific timeout handling. - Refactored runAgent and handleChatMessage methods to utilize the new idle timeout logic. - Implemented AnnotateTimeout method in session.Store to cleanly close conversation turns on timeout. - Created shared ExtendableDeadline package for managing timeout behavior across app and gateway components. - Added comprehensive tests for timeout resolution and behavior in various scenarios. --- internal/adk/errors.go | 16 ++- internal/adk/state_test.go | 8 +- internal/app/channels.go | 80 ++++++++---- internal/app/channels_test.go | 53 ++++++++

The v0.7 EntryPoint (`0x0000000071727De22E5E9d8BAf0edAc6f37da032`) expects split fields: `initCode` → `factory`+`factoryData`, `paymasterAndData` → `paymaster`+gas limits+`paymasterData`.

Splitting only at RPC boundary keeps the internal model clean and avoids breaking session signing, hash computation, and all existing consumers. + +**Alternative**: Add separate `Factory`/`FactoryData` fields to `UserOperation` — rejected because it would require updating every constructor and consumer. + +### 2. EIP-2612 permit builder as a separate package + +**Decision**: `internal/smartaccount/paymaster/permit/` package with `PermitSigner` and `EthCaller` interfaces. + +**Rationale**: Follows the existing `internal/payment/eip3009/` pattern.

Mitigation: This is generous for gas costs on Base Sepolia; can be made configurable later if needed. +- **[Permit nonce race]** → If multiple UserOps are submitted concurrently, permit nonces could collide.

Subject: [PATCH 32/52] feat: implement two-level hierarchical navigation in settings TUI - Introduced a two-level menu structure to enhance navigation, displaying 7 sections at Level 1 and categories at Level 2. - Added methods to `MenuModel` for managing navigation state and rendering items based on the current level. - Updated `editor.go` to handle transitions between levels and adjust breadcrumb display accordingly. - Enhanced tests to cover new navigation flows and ensure functionality across both levels. - Modified help bar to reflect context-sensitive actions based on the current navigation level. --- internal/cli/settings/editor.go | 12 +- internal/cli/settings/editor_test.go | 119 ++++++++++++ internal/cli/settings/menu.go | 176 ++++++++++++++---- .../.openspec.yaml

From: langowarny Date: Sun, 15 Mar 2026 20:16:35 +0900 Subject: [PATCH 33/52] feat: implement dependency discovery system in settings TUI - Introduced a comprehensive dependency registry to manage feature prerequisites, enhancing user experience by making hidden dependencies visible. - Added `DependencyIndex`, `DependencyPanel`, and `SetupFlow` components to facilitate dependency evaluation, navigation, and guided setup. - Implemented a `DependencyChecker` in `MenuModel` to display unmet dependencies with warning badges and a new `@ready` filter for configurable categories. - Refactored `handleMenuSelection` to utilize a shared form creation function, reducing code duplication. - Enhanced tests to cover new functionality, including dependency evaluation and setup flow processes. ---

Features have implicit dependencies (e.g., Smart Account requires Payment + Security Signer) that are invisible to users. When a feature is enabled without its prerequisites, tools silently fail to register — causing confusion even for developers. + +Current architecture: `Editor` (state machine) → `MenuModel` (navigation) → `FormModel` (per-category forms). Existing patterns include `EnabledChecker` and `DirtyChecker` callbacks on `MenuModel` for smart filters. + +## Goals / Non-Goals + +**Goals:** +- Make feature dependency chains visible at all three interaction layers (menu, form entry, guided setup) +- Enable users to discover and resolve prerequisites without leaving the settings flow +- Codify all 20+ dependency relationships in a single, testable registry +- Eliminate duplicated form-creation logic between `handleMenuSelection()` and setup flow + +**Non-Goals:** +- Auto-enabling prerequisites (users must explicitly configure each feature) +- Runtime dependency checking outside the settings TUI +- Dependency cycle support (the graph is acyclic by design) +- Changing the underlying config structure + +## Decisions + +### 1. Callback-based DependencyChecker on MenuModel +**Decision**: Add `DependencyChecker func(string) int` callback to `MenuModel`, following the established `EnabledChecker`/`DirtyChecker` pattern. +**Rationale**: Consistent with existing architecture. Avoids coupling `MenuModel` to the dependency system directly. +**Alternative**: Passing `DependencyIndex` directly to `MenuModel` — rejected because it breaks the callback abstraction used by other checkers. + +### 2. Closure-based Check functions in dependency registry +**Decision**: Each `Dependency` holds a `Check func(cfg *config.Config) DepStatus` closure that evaluates against config. +**Rationale**: Flexible — each dependency can inspect any combination of config fields. Shared functions (`checkSmartAccountEnabled`, `checkP2PEnabled`, `checkEconomyEnabled`) avoid duplication for common patterns. +**Alternative**: Declarative field-path checking — rejected because some checks require multi-field logic (e.g., Payment enabled AND RPC URL not empty). + +### 3. Depth-first transitive resolution with visited set +**Decision**: `AllTransitiveUnmet()` uses recursive depth-first traversal with a `visited map[string]bool` to prevent infinite loops. +**Rationale**: Ensures children appear before parents in the result (important for guided setup ordering). Visited set is a safety net even though the graph is acyclic. + +### 4. Shared `createFormForCategory()` factory +**Decision**: Extract form creation into a single `createFormForCategory()` function used by both `handleMenuSelection()` and `SetupFlow`. +**Rationale**: Eliminates 150+ lines of duplicated switch logic. Single source of truth for category→form mapping. + +### 5. Navigation stack for jump-to-dependency +**Decision**: Use `navStack []string` in `Editor` to track jumped-from categories, enabling Esc to return to the original form. +**Rationale**: Simple, bounded by graph depth (~8 max). No need for more complex navigation management. + +## Risks / Trade-offs + +- [Stale dependency data] → DependencyChecker re-evaluates on each render. Since checks are trivial struct field reads, performance impact is negligible. +- [New category requires two changes] → Adding a form category requires updating both `createFormForCategory()` and `NewMenuModel()`. This is a pre-existing pattern, not a regression. +- [Panel focus management] → `panelFocus bool` must be manually synced with `depPanel` lifecycle.

Registered disabled categories (cron, background, workflow) in the tool catalog to improve visibility in `builtin_health`. - Enhanced `builtin_health` to include actionable configuration hints and tool name lists for enabled categories. - Introduced a dynamic `SectionToolCatalog` in the system prompt to display active tool categories and their tools. - Added logging for tool registration summary at application startup for better diagnostics. - Updated orchestrator routing entries to include tool names for improved agent delegation. --- internal/app/app.go | 48 ++++++++ internal/app/tools_automation.go | 24 +++- internal/app/wiring.go | 50 ++++++++ internal/background/manager.go | 6 + internal/background/manager_test.go | 56 +++++++++ internal/background/task.go | 10 ++ internal/cron/executor.go | 40 +++++- internal/cron/executor_test.go | 92 ++++++++++++++ internal/cron/scheduler.go | 50 ++++++++ internal/cron/scheduler_test.go | 100 +++++++++++++++ internal/orchestration/orchestrator.go | 2 +- internal/orchestration/orchestrator_test.go | 4 +- internal/orchestration/tools.go | 22 +++- internal/prompt/section.go | 5 +- internal/toolcatalog/catalog.go | 35 ++++++ internal/toolcatalog/dispatcher.go | 11 +- internal/toolcatalog/dispatcher_test.go | 36 +++++- internal/workflow/engine.go | 18 ++- internal/workflow/engine_test.go | 114 ++++++++++++++++++ .../.openspec.yaml | 2 + .../design.md | 42 +++++++ .../proposal.md | 30 +++++ .../specs/tool-catalog/spec.md | 38 ++++++ .../specs/tool-health-diagnostics/spec.md | 41 +++++++ .../tasks.md | 41 +++++++ .../.openspec.yaml | 2 + .../fix-automation-systems-bugs/design.md | 57 +++++++++ .../fix-automation-systems-bugs/proposal.md | 35 ++++++ .../specs/background-execution/spec.md | 32 +++++ .../specs/cron-scheduling/spec.md | 87 +++++++++++++ .../specs/workflow-engine/spec.md | 27 +++++ .../fix-automation-systems-bugs/tasks.md | 54 +++++++++ openspec/specs/background-execution/spec.md | 16 +++ openspec/specs/cron-scheduling/spec.md | 63 +++++++++- openspec/specs/tool-catalog/spec.md | 37 ++++++ .../specs/tool-health-diagnostics/spec.md | 28 ++++- openspec/specs/workflow-engine/spec.md | 26 ++++ 37 files changed, 1355 insertions(+), 26 deletions(-) create mode 100644 internal/workflow/engine_test.go create mode 100644 openspec/changes/archive/2026-03-15-fix-tool-discovery-diagnosis/.openspec.yaml create mode 100644 openspec/changes/archive/2026-03-15-fix-tool-discovery-diagnosis/design.md create mode 100644 openspec/changes/archive/2026-03-15-fix-tool-discovery-diagnosis/proposal.md create mode 100644 openspec/changes/archive/2026-03-15-fix-tool-discovery-diagnosis/specs/tool-catalog/spec.md create mode 100644 openspec/changes/archive/2026-03-15-fix-tool-discovery-diagnosis/specs/tool-health-diagnostics/spec.md create mode 100644 openspec/changes/archive/2026-03-15-fix-tool-discovery-diagnosis/tasks.md create mode 100644 openspec/changes/fix-automation-systems-bugs/.openspec.yaml create mode 100644 openspec/changes/fix-automation-systems-bugs/design.md create mode 100644 openspec/changes/fix-automation-systems-bugs/proposal.md create mode 100644 openspec/changes/fix-automation-systems-bugs/specs/background-execution/spec.md create mode 100644 openspec/changes/fix-automation-systems-bugs/specs/cron-scheduling/spec.md create mode 100644 openspec/changes/fix-automation-systems-bugs/specs/workflow-engine/spec.md create mode 100644 openspec/changes/fix-automation-systems-bugs/tasks.md diff --git a/internal/app/app.go b/internal/app/app.go index f08dc19d8..2c761b805 100644 --- a/internal/app/app.go +++ b/internal/app/app.go @@ -424,6 +424,32 @@ func New(boot *bootstrap.Result) (*App, error) { logger().Info("workflow tools registered") } + // Register disabled categories for systems that are off, so builtin_health can report them. + if !cfg.Cron.Enabled { + catalog.RegisterCategory(toolcatalog.Category{ + Name: "cron", + Description: "Cron job scheduling (disabled)", + ConfigKey: "cron.enabled", + Enabled: false, + }) + } + if !cfg.Background.Enabled { + catalog.RegisterCategory(toolcatalog.Category{ + Name: "background", + Description: "Background task execution (disabled)", + ConfigKey: "background.enabled", + Enabled: false, + }) + } + if !cfg.Workflow.Enabled { + catalog.RegisterCategory(toolcatalog.Category{ + Name: "workflow", + Description: "Workflow pipeline execution (disabled)", + ConfigKey: "workflow.enabled", + Enabled: false, + }) + } + // 5m.

Separate singleton and Safe7579 addresses in Factory + +**Decision**: Add a dedicated `singletonAddr` field to `Factory` struct, distinct from `safe7579Addr`. Update `NewFactory` to accept both as separate parameters. + +**Rationale**: The Safe proxy factory's `createProxyWithNonce(_singleton, initializer, saltNonce)` creates a proxy that delegates to `_singleton`. The singleton must be the Safe L2 implementation (which has `setup()`). The Safe7579 adapter is only called via delegate call during setup (the `to` parameter in `setup()`). Passing Safe7579 as the singleton caused the proxy to delegate to a contract without `setup()`, reverting immediately. + +**Alternative**: Hardcode the singleton address -- rejected because different chains may deploy Safe L2 at different addresses. + +### 2. SafeSingletonAddress config field with default + +**Decision**: Add `SafeSingletonAddress` to `SmartAccountConfig`. If empty, default to `0x29fcB43b46531BcA003ddC8FCB67FFE91900C762` (Safe L2 v1.4.1 on major chains). + +**Rationale**: Safe L2 v1.4.1 is the canonical implementation on Ethereum, Polygon, Base, Arbitrum, Optimism.

The existing `jsonrpcError` struct lacked this field entirely. The decoder is reused by `contract.Caller` for go-ethereum `DataError` extraction. + +### 4. eth_call replay for receipt-level reverts + +**Decision**: When a confirmed transaction has `receipt.Status != 1`, replay the same call as `eth_call` at the revert block to extract the revert reason. + +**Rationale**: Transaction receipts do not include revert reasons. Replaying as `eth_call` triggers the same EVM execution and returns the revert data in the error. This is the standard technique used by Etherscan and Foundry. + +### 5.

319f89797b9606d53e01e0049b7fa893ba13630a Mon Sep 17 00:00:00 2001 From: langowarny Date: Mon, 16 Mar 2026 23:24:22 +0900 Subject: [PATCH 42/52] feat: add parity verification tests for app initialization - Introduced a new test file `parity_test.go` to validate the behavior of `app.New()` and related functions. - Implemented Layer 1 unit tests for helper functions like `buildCatalogFromEntries` and `registerPostBuildLifecycle`, ensuring correct category and tool registration. - Added Layer 2 integration tests to verify application state with default and feature-enabled configurations, checking for expected lifecycle components and field population. - Enhanced `lifecycle.Registry` with a new `Names()` method to retrieve registered component names in order, improving test introspection. - Updated documentation to reflect the new testing capabilities and structure. --- internal/app/parity_test.go | 284 ++++++++++++++++++

43/52] feat: implement tool call accumulator to handle streaming deltas - Introduced `toolCallAccumulator` to assemble streaming tool call deltas into complete `FunctionCall` parts, addressing issues with empty names in OpenAI API requests. - Enhanced `ModelAdapter.GenerateContent` to utilize the accumulator for both streaming and non-streaming paths, ensuring correct assembly of tool calls. - Added defensive filters in `convertMessages()` and `convertParams()` to skip entries with empty names, improving robustness against upstream bugs. - Implemented comprehensive tests for the new accumulator functionality and its integration with existing systems. --- internal/adk/model.go | 208 ++++++++- internal/adk/model_test.go | 397 ++++++++++++++++++ internal/adk/session_service.go | 16

Added `shutdownCtx` and `shutdownCancel` to the `Server` struct to manage cancellation of ongoing requests during shutdown. - Updated `handleChatMessage()` to derive request contexts from `shutdownCtx`, ensuring they are cancelled when `Shutdown()` is invoked. - Enhanced `Shutdown()` method to call `shutdownCancel()` before closing WebSocket connections, allowing for immediate cancellation of pending approvals and in-flight requests. - Introduced tests to verify that in-flight request contexts are cancelled correctly and that `RequestApproval()` returns `context.Canceled` during shutdown. --- internal/gateway/server.go | 12 +++- internal/gateway/server_test.go | 68 +++++++++++++++++++ .../.openspec.yaml | 2 + .../design.md | 37 ++++++++++ .../proposal.md | 24 +++++++ .../specs/gateway-server/spec.md | 53 +++++++++++++++ .../tasks.md | 17 +++++ openspec/specs/gateway-server/spec.md | 22 +++++- 8 files changed, 232 insertions(+), 3 deletions(-) create mode 100644 openspec/changes/archive/2026-03-17-fix-shutdown-inflight-context/.openspec.yaml create mode 100644 openspec/changes/archive/2026-03-17-fix-shutdown-inflight-context/design.md create mode 100644 openspec/changes/archive/2026-03-17-fix-shutdown-inflight-context/proposal.md create mode 100644 openspec/changes/archive/2026-03-17-fix-shutdown-inflight-context/specs/gateway-server/spec.md create mode 100644 openspec/changes/archive/2026-03-17-fix-shutdown-inflight-context/tasks.md diff --git a/internal/gateway/server.go b/internal/gateway/server.go index 6e864313a..ac237dd9c 100644 --- a/internal/gateway/server.go +++ b/internal/gateway/server.go @@ -51,6 +51,8 @@ type Server struct { pendingApprovalsMu sync.Mutex turnCallbacks []TurnCallback sanitizer *gatekeeper.Sanitizer + shutdownCtx context.Context + shutdownCancel context.CancelFunc } // Config holds gateway server configuration @@ -105,6 +107,7 @@ type RPCHandler func(client *Client, params json.RawMessage) (interface{}, error // New creates a new gateway server func New(cfg Config, agent *adk.Agent, provider *security.RPCProvider, store session.Store, auth *AuthManager) *Server { originChecker := makeOriginChecker(cfg.AllowedOrigins) + shutdownCtx, shutdownCancel := context.WithCancel(context.Background()) s := &Server{ config: cfg, @@ -116,6 +119,8 @@ func New(cfg Config, agent *adk.Agent, provider *security.RPCProvider, store ses clients: make(map[string]*Client), handlers: make(map[string]RPCHandler), pendingApprovals: make(map[string]chan approval.ApprovalResponse), + shutdownCtx: shutdownCtx, + shutdownCancel: shutdownCancel, upgrader: websocket.Upgrader{ ReadBufferSize: 1024, WriteBufferSize: 1024, @@ -200,11 +205,11 @@ func (s *Server) handleChatMessage(client *Client, params json.RawMessage) (inte } if idleTimeout > 0 { -

Scanning backward for the nearest assistant message's matching ToolCall ID provides a reasonable fallback. Only checks the nearest assistant to avoid wrong inference. +**Alternative**: Require migration of all sessions → too disruptive for users. + +### D4: Narrow ThoughtSignature defense (not blanket drop) +**Rationale**: Only `Thought=true && ThoughtSignature empty` is corrupted (persistence lost the signature). `Thought=false && ThoughtSignature empty` is normal for non-thinking models.

From 8d4ac2b14078c7e1f667c8fe794355f507e25f98 Mon Sep 17 00:00:00 2001 From: langowarny Date: Tue, 17 Mar 2026 22:47:16 +0900 Subject: [PATCH 49/52] fix: resolve fallback model leakage, enhance provider-model validation - Modified `ProviderProxy.Generate()` to reset `params.Model` to an empty string before invoking the fallback provider, ensuring the correct fallback model is applied. - Introduced `ValidateModelProvider()` function to validate model-provider compatibility using a heuristic prefix blocklist, preventing cross-provider model routing errors. - Enhanced `config.Validate()` to check for the existence of `agent.fallbackProvider` in the providers map and validate both primary and fallback model-provider pairs. - Added runtime validation in Gemini and Anthropic providers to ensure model compatibility before making API calls. - Created new tests for the fallback mechanism and model validation to ensure robustness and correctness. --- internal/config/loader.go | 26 +++ internal/provider/anthropic/anthropic.go | 5 + internal/provider/gemini/gemini.go | 5 + internal/provider/validate.go | 46 ++++++ internal/provider/validate_test.go | 77 +++++++++ internal/supervisor/proxy.go | 4 +- internal/supervisor/proxy_test.go | 149 ++++++++++++++++++ .../.openspec.yaml | 2 + .../design.md | 46 ++++++ .../proposal.md | 29 ++++ .../specs/config-system/spec.md | 23 +++ .../specs/provider-interface/spec.md | 23 +++ .../specs/provider-model-validation/spec.md | 28 ++++ .../specs/supervisor-architecture/spec.md | 16 ++ .../tasks.md | 26 +++ openspec/specs/config-system/spec.md | 22 +++ openspec/specs/provider-interface/spec.md | 22 +++ .../specs/provider-model-validation/spec.md | 32 ++++ .../specs/supervisor-architecture/spec.md | 15 ++ 19 files changed, 595 insertions(+), 1 deletion(-) create mode 100644 internal/provider/validate.go create mode 100644 internal/provider/validate_test.go create mode 100644 internal/supervisor/proxy_test.go create mode 100644 openspec/changes/archive/2026-03-17-fix-fallback-model-leak/.openspec.yaml create mode 100644 openspec/changes/archive/2026-03-17-fix-fallback-model-leak/design.md create mode 100644 openspec/changes/archive/2026-03-17-fix-fallback-model-leak/proposal.md create mode 100644 openspec/changes/archive/2026-03-17-fix-fallback-model-leak/specs/config-system/spec.md create mode 100644 openspec/changes/archive/2026-03-17-fix-fallback-model-leak/specs/provider-interface/spec.md create mode 100644 openspec/changes/archive/2026-03-17-fix-fallback-model-leak/specs/provider-model-validation/spec.md create mode 100644 openspec/changes/archive/2026-03-17-fix-fallback-model-leak/specs/supervisor-architecture/spec.md create mode 100644 openspec/changes/archive/2026-03-17-fix-fallback-model-leak/tasks.md create mode 100644 openspec/specs/provider-model-validation/spec.md diff --git a/internal/config/loader.go b/internal/config/loader.go index 6e5cb647b..e89285de2 100644 --- a/internal/config/loader.go +++ b/internal/config/loader.go @@ -9,6 +9,7 @@ import ( "strings" "time" + "github.com/langoai/lango/internal/provider" "github.com/langoai/lango/internal/types" "github.com/spf13/viper" ) @@ -384,6 +385,31 @@ func Validate(cfg *Config) error { } } + // Validate agent.fallbackProvider references an existing key in providers map + if cfg.Agent.FallbackProvider != "" && len(cfg.Providers) > 0 { + if _, ok := cfg.Providers[cfg.Agent.FallbackProvider];

original `params` (with `params.Model` still set to the primary model name, e.g., `gpt-5.3-codex`) to the fallback provider. `Supervisor.Generate()` only applies the fallback model when `params.Model == ""`, so the primary model leaks through to the fallback provider — causing requests like `gemini-3-flash-preview` provider receiving `gpt-5.3-codex` as the model name, resulting in API errors (e.g., Gemini URL: `models/gpt-5.3-codex:streamGenerateContent`). + +## What Changes + +- **Fix**: `proxy.go` — copy `params` before fallback call and reset `Model` to `""` so `Supervisor.Generate()`
