2026-05-11 + +### Fixed +- `Subscription#activate` now checks `channel.open?` before calling `subscribe_with`; if closed, it re-prepares once and retries, preventing silent activation failures when a channel is closed between prepare and activate. +- `Transport` mixin now guards `auto_create_dlx_exchange` and `auto_create_dlx_queue` with a `remote_invocable?` check — non-remote extensions no longer attempt to create dead-letter exchanges and queues they never use. +- DLX exchange type corrected from `fanout` to `topic` for consistency with the rest of the exchange topology. +- Identity resolver DB persistence now uses Sequel models (`Identity::Provider`, `Identity::Principal`, `Identity::Identity`, `Identity::AuditLog`) instead of raw `Legion::Data.db` dataset calls that didn't exist on the module. +- Identity audit API endpoint now references correct column names (`detail_payload`, `node_ref`, `session_ref`) matching the schema. +- Fixed `LeaseRenewer#log_renewal_failure` to fall back to `$stderr` when `Legion::Logging` is not yet loaded, matching the original contract. +- Fixed `Legion::Service#log_privacy_mode_status`, `#shutdown_component`, and TLS-fallback logging specs to assert against `emit_tagged` (the actual dispatch path used by `Legion::Logging::Helper`) rather than `Legion::Logging.warn/info` directly. +- Fixed `Cluster::Leader` boot integration spec to stub `Legion::Settings[:logging]` so `log` helper initialization does not raise on unexpectedly-received arguments. + +### Changed +- Added `remote_invocable_extension?` helper to the `Transport` module; returns `lex_class.remote_invocable?` when available, `true` otherwise. +- Refactored `Identity::Resolver#persist_to_db` into extracted helpers (`upsert_providers`, `upsert_principal`, `upsert_identities`, `upsert_single_identity`) to reduce method complexity and improve readability. +- Replaced hand-rolled `log_warn`/`log_debug` methods in `Identity::Resolver`, `Identity::Broker`, and `Identity::LeaseRenewer` with `include Legion::Logging::Helper` and standard `log.debug`/`log.warn` calls. +- Added debug logging throughout `Identity::Resolver` for registration, resolution, auth racing, binding, and DB persistence. +- LLM inference API now passes `instance` and `tier` routing hints from request body through to `Legion::LLM::Inference::Request`. + +## [1.9.28] - 2026-05-08 + +### Fixed +- Task outcome observation now ignores internal runner completions without task ids, preventing periodic mesh gossip ticks from feeding meta-learning and Apollo ingestion. +- Identity resolver database persistence now targets the current identity provider, principal, identity, and audit log schema. + +## [1.9.27] - 2026-05-08 + +### Fixed +- Preserve omitted `/api/llm/inference` client tool definitions as absent instead of `tools: []`, allowing legion-llm registry and trigger-based tool injection to run for normal API requests. +- Added an opt-in live daemon integration spec suite that uses explicit Faraday test dependencies and its own isolated RSpec helper. + +## [1.9.26] - 2026-05-07 + +### Fixed +- Use the local `Legion::Identity::Process` identity for unauthenticated loopback API principals even when the process is only fallback-bound, avoiding generic `system:system` attribution in downstream LLM audit flows. + +## [1.9.25] - 2026-05-07 + +### Fixed +- Updated identity model references in `identity_audit.rb` and `identity/broker.rb` to use the portable namespace (`Identity::AuditLog`, `Identity::Principal`, `Identity::GroupMembership`) after legacy top-level identity models were removed from legion-data. + +## [1.9.24] - 2026-05-07 + +### Changed +- Removed deprecated direct AI provider extensions (`lex-azure-ai`, `lex-bedrock`, `lex-claude`, `lex-foundry`, `lex-gemini`, `lex-ollama`, `lex-openai`) from the extension catalog; use their `lex-llm-*` counterparts instead. + +## [1.9.23] - 2026-05-07 + +### Fixed +- Fixed encrypted subscription handling to accept both string-keyed and symbol-keyed IV headers before decrypting `encrypted/cs` AMQP payloads. + +## [1.9.22] - 2026-05-06 + +### Changed +- Hot-reloading a `lex-llm-*` provider extension now asks `Legion::LLM::Call::Providers` to rediscover loaded provider modules, keeping LLM provider instances aligned after extension updates. +- Bumped the packaged `legion-llm` dependency floor to `>= 0.9.1` for LLM-owned provider registration and reload-safe registry rebuilds. + +## [1.9.21] - 2026-05-06 + +### Changed +- LegionIO now mounts `Legion::LLM::Routes` through the library route selector when `legion-llm` is available, leaving LLM API ownership with `legion-llm` instead of registering partial fallback routes first. +- LLM provider health API and CLI output now require native `Legion::LLM::Inventory` data and return a clear unavailable response when inventory is not loaded. +- Bumped packaged dependency floors to `legion-llm >= 0.9.0` and `legion-data >= 1.8.0` for the coordinated LLM route/schema sweep. + +### Fixed +- Lite and local mode startup now write development mode through the public `Legion::Settings.set_prop` API. + +### Removed +- Removed active `lex-llm-gateway` fallback paths from LLM chat, provider health, extension catalog, role filtering, and README documentation. + +## [1.9.20] - 2026-05-06 + +### Fixed +- Nested LEX extensions now merge default settings into their nested `extensions` path (for example `lex-foo-bar` -> `extensions.foo.bar`) while underscored flat extensions continue to use the flat key (for example `lex-foo_bar` -> `extensions.foo_bar`). +- Extension load-time settings checks now use the discovered settings path for nested extensions, keeping `enabled`, `min_version`, `workers`, and `remote_invocable` overrides aligned with where defaults are merged. + +## [1.9.19] - 2026-05-05 + +### Added +- `UnrecoverableMessageError` for messages that should be dead-lettered immediately (e.g., missing IV header on encrypted messages) instead of retried. +- Subscription actors now extract `message_id` and `correlation_id` from AMQP metadata into the message hash for downstream tracing. +- Runner builder auto-includes `Helpers::Lex` into runner modules when available, ensuring all runners have LEX metadata helpers. + +### Fixed +- Encrypted messages (`encrypted/cs`) with a missing `iv` header now raise `UnrecoverableMessageError` and are dead-lettered rather than crashing with a nil argument to `Crypt.decrypt`. + +## [1.9.18] - 2026-04-29 + +### Fixed +- API-submitted LLM tools now build native `Legion::LLM::Types::ToolDefinition` objects instead of attempting to require RubyLLM at runtime. +- Provider route coverage now locks LegionIO's `/api/llm/providers` compatibility response ahead of later colliding LLM library route registrations. + +## [1.9.17] - 2026-04-29 + +### Fixed +- LegionIO now requires `legion-llm >= 0.8.47` and only uses a local sibling `legion-llm` checkout when it satisfies that release floor, preventing stale local worktrees from breaking Bundler resolution. +- Native LLM provider health API responses now preserve model, type, health, and instance fields when inventory offerings are loaded from string-keyed data. + +## [1.9.16] - 2026-04-28 + +### Fixed +- LegionIO now requires `legion-llm >= 0.8.44` so packaged installs include the unified identity migration for LLM caller metadata and Broker token audit context. + +## [1.9.15] - 2026-04-28 + +### Fixed +- The static extension catalog now classifies `lex-llm-gateway` as legacy compatibility, and setup pack tests explicitly prevent it from returning to default LLM or agentic installs. +- README LLM documentation now calls out `lex-llm-gateway` as legacy-only compatibility glue that is not installed by default. + +## [1.9.14] - 2026-04-28 + +### Fixed +- LegionIO now requires `legion-tty >= 0.5.4` so packaged installs include the Legion-native LLM probe instead of the legacy direct RubyLLM probe. + +## [1.9.13] - 2026-04-28 + +### Fixed +- LegionIO now requires `legion-llm >= 0.8.43` so packaged installs get the optional RubyLLM compatibility layer and native dispatch fallback defaults. + +## [1.9.12] - 2026-04-28 + +### Fixed +- LegionIO now requires `legion-llm >= 0.8.42` so packaged installs resolve the validated LLM routing uplift release. + +## [1.9.11] - 2026-04-28 + +### Fixed +- LLM chat API routing now prefers native `Legion::LLM.chat` even when legacy `lex-llm-gateway` compatibility code is loaded. + +## [1.9.10] - 2026-04-28 + +### Fixed +- LLM provider health endpoints and CLI health checks now use the native `legion-llm` provider inventory before falling back to legacy `lex-llm-gateway` provider stats. + +## [1.9.9] - 2026-04-28 + +### Fixed +- Registry governance and security scanning now accept nested `lex-*` extension gem names such as `lex-llm-openai` and `lex-llm-azure-foundry`. + +## [1.9.8] - 2026-04-28 + +### Fixed +- The `agentic` setup pack now installs the Legion-native `lex-llm-*` provider stack without also installing retired legacy LLM provider gems. +- Role profiles now treat `lex-llm-*` gems as the active AI extension set and exclude legacy LLM providers from default `core`, `dev`, and `cognitive` profile loading. +- LegionIO now requires `legion-llm >= 0.8.41` so packaged installs get the router dependency cleanup that removes retired legacy provider runtime dependencies. + +## [1.9.7] - 2026-04-28 + +### Fixed +- Extension discovery now maps `lex-llm-azure-foundry` to `Legion::Extensions::Llm::AzureFoundry` and `legion/extensions/llm/azure_foundry`. +- LegionIO now requires `legion-llm >= 0.8.40` so packaged installs include the native provider bridge needed by the Legion-native LLM stack. +- README LLM provider documentation now describes the `lex-llm-*` provider stack instead of the retired legacy provider list. + +## [1.9.6] - 2026-04-28 + +### Fixed +- LLM API gateway checks now use the `Legion::Extensions::Llm::Gateway` namespace loaded by Legion extension autoloading. +- LLM inference and skill invocation routes now call the current `Legion::LLM::Inference` request/executor API instead of the retired pipeline constants. +- `legionio llm ping` now routes through `Legion::LLM.ask_direct` instead of bypassing Legion routing with a raw RubyLLM call. +- API client tool construction now degrades cleanly when the RubyLLM tool base is unavailable. + +## [1.9.5] - 2026-04-28 + +### Added +- Extension catalog, setup packs, and local development wiring now include the Legion-native `lex-llm` provider stack, including Bedrock, Azure Foundry, and Vertex hosted provider extensions. + +### Fixed +- Local development Gemfile wiring now includes guarded `lex-llm-ledger` resolution so the local bundle matches the LLM setup pack. +- Local development Gemfile wiring now points `lex-llm-gateway` at the workspace extension path actually used by LegionIO checkouts. +- Default setup packs no longer install legacy `lex-llm-gateway`; the extension catalog now labels it as compatibility glue rather than active LLM routing. +- `require 'legion/extensions'` now loads its logging dependency directly instead of relying on `require 'legion'` order. + +## [1.9.4] - 2026-04-27 + +### Added +- Extension boot now runs a dedicated LLM load phase so `lex-llm` loads before any `lex-llm-*` extension gems. +- `/api/health` now reports `uptime_seconds` and `uptime` for dashboard and monitor consumers. Fixes #168 +- `/api/extensions` now returns a flat loaded-extension summary for dashboard consumers. Fixes #169 + +### Fixed +- `legionio doctor` no longer reports extension-loader config keys as missing `lex-*` gems. Fixes #157 +- `/api/metering` now returns dashboard headline totals instead of the routing breakdown shape. Fixes #170 +- Extension autobuild now runs per-extension data migrations when migration files are present, even when an extension does not opt into general data models. Fixes #171 +- `/api/webhooks` now loads its `Legion::Webhooks` runtime dependency before route handlers execute. Fixes #172 +- `/api/tenants` now passes positional response data and uses `json_error` for missing tenants. Fixes #173 + +## [1.9.3] - 2026-04-27 + +### Fixed +- Extension catalog persistence now skips no-op startup updates when the stored state already matches, reducing local SQLite write churn. Fixes #176 + +## [1.9.2] - 2026-04-27 + +### Fixed +- `POST /api/knowledge/status` no longer silently defaults to the daemon's cwd. Uses `knowledge.default_corpus_path` setting or `LEGION_CORPUS_PATH` env var; returns 400 when unresolvable. Prevents `Errno::EPERM` crashes on macOS when the daemon is launched from `~` and `Find.find` walks into TCC-protected subdirs like `~/Library/Accounts`. + +## [1.9.1] - 2026-04-25 + +### Added +- Extension runtime handles now expose authoritative active/latest versions, reload state, pending-reload status, hot-reload eligibility, and owned runtime resources through `/api/extension_catalog`. +- Extension dispatch quiescing now blocks API, ingress, and subscription runner dispatch while an extension is stopping or actively reloading. +- `Legion::Tools::Registry.unregister_extension` removes callable tools owned by an extension during unload/reload cleanup. + +### Fixed +- Runtime handle `loaded?` no longer reports `stopped` or `failed` extensions as loaded. +- Extension registration publication now happens after extension autobuild and runtime side effects complete, avoiding durable registration of failed loads. +- Extension runtime handles now transition to loaded only after `require` and extension side effects succeed, and multi-segment extension modules keep their hyphenated lex identity. + +## [1.9.0] - 2026-04-24 + +### Added +- `Legion::Identity::Resolver` — composite identity resolution chain with parallel provider execution, DB persistence, and transport event publishing +- `Legion::Identity::Trust` — trust level enum (verified, authenticated, configured, cached, unverified) +- `Legion::Identity::Grant` — frozen value object for credential access auditing +- `Identity::Process` extended with trust, aliases, providers, profile composite state +- `Identity::Broker` upgraded to `[provider, qualifier]` tuple-keyed multi-instance storage with `for_context` routing and bounded async audit queue +- `Resolver.upgrade!` for post-boot identity trust escalation with canonical_name change support +- Settings client name updated from resolved identity for correct queue naming + +### Changed +- `setup_identity` gate relaxed to run with DB-only nodes (not just transport) +- `register_credential_providers` gate relaxed for DB-only nodes +- Reload lifecycle: `Resolver.reset!` preserves providers, re-resolves with existing registrations +- Middleware `system_principal` uses Resolver identity when available + +### Fixed +- `Request.from_auth_context` canonical normalization now matches DB constraint `^[a-z0-9][a-z0-9_-]*$` +- `/api/identity/audit` reads from `identity_audit_log` table instead of `AuditRecord` + +### Removed +- Legacy tree-walk identity discovery (`resolve_identity_providers`, `find_identity_providers`, `collect_identity_providers`) +- `identity_provider?` and `register_identity_provider` from extensions.rb + +## [1.8.16] - 2026-04-22 + +### Added +- `legion mind-growth wire ID` CLI command — wires a built extension into the cognitive tick cycle via `Orchestrator.post_build_pipeline`; accepts `--phase` override option + +### Fixed +- `MindGrowth#wire` rescue block now logs errors via `Legion::Logging.error` before displaying them, ensuring errors are captured in the daemon log and not only printed to the terminal + +## [1.8.15] - 2026-04-22 + +### Fixed +- `legionio knowledge ingest ` no longer returns `API 500 for /api/knowledge/ingest`. Two halves of the same contract mismatch: (a) the CLI previously forwarded `dry_run:` on every call (now only when `--dry-run` is passed), and (b) the `/api/knowledge/ingest` route forwarded `dry_run:` to `Legion::Extensions::Knowledge::Runners::Ingest.ingest_file`, whose signature in `lex-knowledge` 0.6.7 is `ingest_file(file_path:, force:)` — causing `ArgumentError: unknown keyword: :dry_run`. The kwarg remains honored for directory (corpus) ingests, which support preview scans. Adds regression coverage in `spec/legion/cli/knowledge_command_spec.rb` (negative-case for file ingest) and a new `spec/api/knowledge_spec.rb` covering the file/directory/dry_run branches of the route. + +## [1.8.14] - 2026-04-18 + +### Fixed +- Optional subsystem `LoadError`s (RBAC, Data, LLM, Apollo, Gaia, Telemetry) now log at the caller-specified level instead of always ERROR with a full stack trace — `handle_exception` respects the `level:` kwarg. Fixes #155 +- `web_fetch` tool in `/api/llm/*` endpoints now delegates to `Legion::CLI::Chat::WebFetch.fetch` instead of bare `Net::HTTP.get`, gaining SSL, redirect-following, HTML-to-markdown conversion, and `maxLength` support. Fixes #153 +- `web_search` tool in `/api/llm/*` endpoints no longer falls through to the generic "not executable server-side" error — added dispatch branch delegating to `Legion::CLI::Chat::WebSearch.search`. Fixes #154 + +## [1.8.13] - 2026-04-17 + +### Added +- `Absorbers::Base#query_knowledge` — scope-aware knowledge retrieval (`:local`, `:global`, `:all`) with deduplication, matching the pattern established by `Helpers::Knowledge` + +### Fixed +- `Absorbers::Base` now routes ingestion by scope: `absorb_to_knowledge`, `absorb_raw`, and `ingest_chunks` resolve `Legion::Apollo::Local` for `:local` scope and `Legion::Apollo` for `:global`, instead of always hitting the global store +- Added `apollo_local_available?` and `resolve_apollo_target` private helpers for scope-driven Apollo target selection + +## [1.8.12] - 2026-04-17 + +### Fixed +- `Actors::Subscription` now supports `pattern` class method as a DSL accessor for routing key hints, delegating to `routing_key_hint` — extensions calling `pattern 'some.routing.key'` no longer raise `NoMethodError`. Fixes #143 +- `Absorbers::Base` removed deprecated `alias handle absorb` — use `#absorb` directly +- Generator template (`legion generate absorber`) now emits `def absorb(...)` instead of `def handle(...)` +- `Matchers::File` is now required and registered alongside `Matchers::Url` in the absorber loader +- Absorber base spec updated to use `#absorb` instead of removed `#handle` alias + +## [1.8.11] - 2026-04-17 + +### Fixed +- `Legion::CLI::Chat::WebFetch` — eliminated all remaining polynomial regex patterns (CodeQL `rb/polynomial-redos`): replaced `convert_blocks!`, `convert_headings!`, `convert_lists!`, `convert_formatting!`, and `strip_remaining_tags!` with index-based tag scanning helpers (`replace_tag_blocks!`, `replace_open_tags!`, `replace_close_tags!`, `replace_self_closing!`). No regex with `[^>]*` or `[^>]+` remains in the HTML-to-markdown pipeline. + +## [1.8.10] - 2026-04-17 + +### Fixed +- `Legion::CLI::Chat::WebFetch#convert_links!` polynomial regex on uncontrolled data (CodeQL `rb/polynomial-redos`) — replaced backtracking `]*href=...>` regex with index-based scanner that walks tag boundaries without backtracking +- Thor `[WARNING] Attempted to create command` noise during rspec — prepend `RSpec::Mocks::AnyInstance::Recorder` to wrap `observe!`, `mark_invoked!`, `restore_original_method!`, and `remove_dummy_method!` inside `Thor.no_commands_context` when the target class is a Thor subclass + +## [1.8.9] - 2026-04-17 + +### Fixed +- `Legion::DigitalWorker::Registry#emit_blocked` passed positional hash to `Legion::Events.emit` which expects kwargs — caused `ArgumentError` masking intended domain exceptions (`WorkerNotFound`, `WorkerNotActive`, `InsufficientConsent`). Fixes #114 + +### Added +- `Legion::Audit::HashChain` now includes `seq` in `CANONICAL_FIELDS` and `verify_chain` detects gaps in sequence numbers, preventing undetected record deletion from the tamper-evident audit chain. Backwards-compatible: gap check is skipped when `seq` is absent. Fixes #149 + +## [1.8.8] - 2026-04-17 + +### Fixed +- `Legion::Ingress` code injection (CodeQL `rb/code-injection`) — replaced `Kernel.const_get` with allowlist lookup against registered extension modules; `resolve_runner_class` now only resolves classes present in `loaded_extension_modules` or `local_tasks` +- `Legion::Graph::Exporter#to_dot` incomplete string escaping (CodeQL `rb/incomplete-sanitization`) — extracted `dot_escape` helper using char-by-char escaping of backslashes and quotes for DOT labels +- `Legion::CLI::Chat::WebFetch#strip_invisible!` polynomial regex / incomplete sanitization / bad tag filter (CodeQL `rb/polynomial-redos`, `rb/incomplete-multi-character-sanitization`, `rb/bad-tag-filter`) — replaced regex `gsub!` with iterative `strip_tag_blocks!` that finds open/close tags by index, eliminating backtracking and handling malformed closing tags + +## [1.8.7] - 2026-04-17 + +### Fixed +- `Legion::CLI::Chat::WebSearch#extract_real_url` incomplete URL substring sanitization (CodeQL `rb/incomplete-url-substring-sanitization`) — replaced `include?('duckduckgo.com')` with `URI.parse` host check using `end_with?` +- `Legion::Tools::EmbeddingCache.clear` now flushes L1/L2 cache tiers in addition to L0 memory, preventing stale lookups after clear + +## [1.8.6] - 2026-04-15 + +### Added +- `Tools::Base#sticky` accessor — tool classes can opt out of sticky runner injection (defaults `true`) +- `Tools::Discovery` propagates `sticky_tools?` from extension to tool class `sticky` attribute; nil treated as opt-out (conservative) +- `Extensions::Core#sticky_tools?` — defaults `true`, extensions may override with `def self.sticky_tools? false end` + +## [1.8.5] - 2026-04-15 + +### Fixed +- `Legion::Extensions::Core#trigger_words` now defaults to `lex_name.split('_')` (e.g. `['github']` for lex-github) instead of `[]`, ensuring extensions auto-surface in TriggerIndex without requiring explicit declaration. Closes #139 +- `Legion::Extensions::Builder::Runners#build_runner_entry` now always populates `trigger_words`, defaulting to `[runner_name]` when the runner module does not define them explicitly. Closes #139 +- `Legion::Tools::Discovery#synthesize_functions` now builds a real JSON Schema from Ruby method reflection data (`Method#parameters`) — required kwargs become required schema properties, optional kwargs become optional properties — so the LLM receives accurate parameter information instead of an empty schema. Closes #140 +- `Legion::Tools::Discovery#synthesize_functions` now uses `definition[:desc]` for tool description when a `definition` DSL entry exists, falling back to the method name rather than `"method_name function"`. Closes #140 +- `Legion::Tools::Discovery#tool_attributes` now reads `definition[:inputs]` when present and non-empty, using it as the input schema in preference to `meta[:options]`. Closes #140 +- `Legion::Tools::Discovery#register_function` fixed asymmetric default: `resolve_exposed` now defaults to `true` when the extension does not respond to `mcp_tools?`, matching the behaviour of `resolve_mcp_tools_enabled`. Closes #140 + +## [1.8.4] - 2026-04-14 + +### Added +- `legionio fleet` CLI subcommand tree: `status`, `pending`, `approve`, `add`, `config` +- `legionio setup fleet` two-phase command: phase 1 installs fleet gems, phase 2 wires relationships via `Workflow::Loader`, seeds conditioner rules, registers settings via `load_module_settings`, merges LLM routing overrides, applies RabbitMQ planner consumer timeout policy +- Fleet pipeline YAML manifest with 10 relationships (1-8 plus 4b, 4c) connecting assessor, planner, developer, and validator +- `Legion::Fleet::SettingsDefaults` — file-based fleet settings persistence +- `Legion::Fleet::ConditionerRules` — supplementary conditioner rule seeds (skip-planning-trivial, skip-validation-trivial, escalate-max-iterations, critical-production-max-capability, governance-mind-growth) +- Fleet API routes: `POST /api/fleet/sources`, `GET /api/fleet/pending` (filters both `fleet.shipping` and `fleet.escalation`), `POST /api/fleet/approve`, `GET /api/fleet/sources`, `GET /api/fleet/status` + +## [1.8.3] - 2026-04-14 + +### Fixed +- `runner_class` resolution for actors nested under `Actor::` namespace — `sub(/Actor$/, 'Runners')` only matched `Actor` at end-of-string, failing for `Extension::Actor::ClassName` patterns (e.g., `Health::Actor::Watchdog`, `Node::Actor::Beat`). Changed to `sub(/::Actor::/, '::Runners::')` which matches the path segment. Affects 9+ actors across lex-health, lex-node, lex-tasker, lex-conditioner, lex-transformer. +- Added defensive guard in `manual` method — raises descriptive `NoMethodError` when `runner_class` resolves to the actor itself and the function is not defined, instead of a generic undefined method error. + +## [1.8.2] -

Detection supports both old and new formats via `hook_commands` helper. + +## [1.6.32] - 2026-03-28 + +### Added +- `POST /api/logs` endpoint (`Routes::Logs`) — accepts `error`/`warn` level messages from CLI, normalizes with server-side metadata (timestamp, node, legion_versions, ruby_version, pid), computes `error_fingerprint` via `EventBuilder.fingerprint` when `exception_class` is present, and publishes to the `legion.logging` exchange with routing key `legion.logging.exception.{level}.cli.{source}` or `legion.logging.log.{level}.cli.{source}` +- `Legion::CLI::ErrorForwarder` module — fire-and-forget HTTP helper that POSTs CLI errors/warnings to the daemon API; silently swallows all failures so daemon unavailability never crashes the CLI +- `ErrorForwarder.forward_error` wired into both rescue blocks in `CLI::Main.start` (fires before `exit(1)`) + +## [1.6.31] - 2026-03-28 + +### Fixed +- `build_hook_list` in `Builders::Hooks` now calls `runner_class` on a hook instance (instance method) instead of the class, preventing the `TypeError: no implicit conversion of nil into String` boot crash caused by `Helpers::Base#runner_class` being inherited at the class level and calling `sub!` on a string that contains no `'Actor'` substring +- `Helpers::Base#runner_class` changed `sub!` to `sub` (non-destructive) as a defensive fix — `sub!` returns `nil` when no substitution is made, which caused `Kernel.const_get(nil)` to raise `TypeError` +- Runner reference returned by `hook_class.new.runner_class` is now resolved safely: string class names are resolved via `Kernel.const_defined?` + `Kernel.const_get`; Class objects are used directly; `nil` falls back to `hook_class` + +## [1.6.30] - 2026-03-28 + +### Fixed +- `Legion::Extensions::Hooks::Base` now defines the `mount(path)` DSL method and `mount_path` reader — fixes `NoMethodError` boot crash in any extension hook that calls `mount` (e.g. `lex-microsoft_teams` `Hooks::Auth`) + +## [1.6.29] - 2026-03-28 + +### Removed +- `ClassMethods` module (`expose_as_mcp_tool`, `mcp_tool_prefix`) from `Legion::Extensions::Helpers::Lex` — deprecated since the definition DSL was introduced; zero extensions use them + +### Fixed +- Fallback route guards in `api.rb` now check `router.library_names.include?` instead of `defined?` — prevents 404s when gem modules are loaded but routes are not yet mounted (fixes #53) + +## [1.6.28] - 2026-03-28 + +### Fixed +- `legion lex list` now displays extensions in clean aligned tables with Name, Version, Status, Runners, Actors columns +- Grouped view drops redundant category/tier columns from rows (already shown in group header); sorts alphabetically within each group +- Flat/category-filtered view uses Name, Version, Category, Status, Runners, Actors columns; sorts alphabetically +- Runners and actors are formatted as comma-joined names (up to 3) or a count summary instead of raw `Array#to_s` output +- JSON output for both flat and grouped list modes is now handled directly in the render methods + +## [1.6.27] - 2026-03-28 + +### Fixed +- `Connection.ensure_crypt` now calls `resolve_secrets!` a second time after `Legion::Crypt.start` so that `lease://` URI refs are resolved once the LeaseManager is running (closes #50) + +## [1.6.26] - 2026-03-28 + +### Added +- Absorber Router registration: `builders/absorbers.rb` now registers absorbers with `Legion::API.router` for v3.0 API discovery and dispatch (component_type: `absorbers`) +- Hook-aware LexDispatch: `POST /api/extensions/:lex/hooks/:name/:method` applies verify/route/transform lifecycle for `Hooks::Base` subclasses; auto-generated hooks pass through unchanged +- Transport message auto-generation: `auto_generate_messages` in `extensions/transport.rb` creates `Legion::Transport::Message` subclasses from runner definitions with inputs at boot time; explicit classes always take precedence +- `legion broker purge-topology` CLI command: detects old v2.0 AMQP exchanges (`legion.*`) that have v3.0 counterparts (`lex.*`) and optionally deletes them via RabbitMQ management API; defaults to `--dry-run` +- `spec/api/lex_dispatch_spec.rb`: 10-example spec covering v3.0 LexDispatch routes (replaces old lex_spec.rb) +- `spec/api/lex_dispatch_hooks_spec.rb`: 5-example spec for hook-aware dispatch (401/422/success/passthrough) +- `spec/api/old_systems_removed_spec.rb`: 10-example spec verifying old registries are gone +- `spec/cli/admin_command_spec.rb`: 21-example spec for topology detection logic +- `spec/extensions/builders/absorbers_spec.rb`: 10-example spec for absorber builder + Router registration +- `spec/extensions/transport_auto_messages_spec.rb`: 14-example spec for message auto-generation +- `unless defined?` guards on `Routes::Gaia`, `Routes::Transport`, `Routes::Rbac` registration for library gem self-registration + +### Removed +- `Routes::Lex` (`api/lex.rb`): old `/api/lex/*` wildcard dispatcher — use `/api/extensions/:lex/runners/:name/:method` +- `Routes::Hooks` (`api/hooks.rb`): old `/api/hooks/lex/*` handler — use `/api/extensions/:lex/hooks/:name/:method` +- `Legion::API.hook_registry`, `.register_hook`, `.find_hook`, `.find_hook_by_path`, `.registered_hooks` — hooks auto-register via builder +- `Legion::API.route_registry`, `.register_route`, `.find_route_by_path`, `.registered_routes` — routes auto-register via builder + +### Changed +- Routes builder log message now uses v3.0 path format (`/api/extensions/...` instead of `/api/lex/...`) + +## [1.6.25] - 2026-03-28 + +### Added +- `Legion::Extensions::Absorbers::Dispatch`: module-function dispatch pipeline — `dispatch(input, context:)`, depth limiting, cycle detection via ancestor_chain, `dispatch_children`, `extract_urls`, thread-safe `@dispatched` registry +- `Legion::Extensions::Absorbers::PatternMatcher`: URL/file pattern registry — `register(absorber_class)`, `resolve(input)`, priority-ordered matching, `reset!` +- `Legion::Extensions::Absorbers::Transport`: v3.0 AMQP topology — `publish_absorb_request`, `build_message`, `lex_name_from_absorber_class`, `absorber_name_from_class`; exchanges named `lex.{lex_name}`, routing keys `lex.{lex_name}.absorbers.{name}.absorb` +- `Legion::Extensions::Absorbers::Base`: updated with `TokenRevocationError`, `TokenUnavailableError`, and `with_token(provider:, &block)` helper for OAuth-gated absorbers +- `Legion::Extensions::Absorbers::Matchers::File`: file-path pattern matcher using `File.fnmatch` +- `Legion::Auth::OauthCallback`: ephemeral TCP server for OAuth redirect callback — `wait_for_callback`, `parse_callback`;

Implemented in `lib/legion/api/library_routes.rb`. +- `Legion::API::SyncDispatch.dispatch(exchange_name, routing_key, payload, envelope, timeout:)`: synchronous AMQP dispatch using a temporary exclusive reply_to queue with configurable timeout (default 30s). Implemented in `lib/legion/api/sync_dispatch.rb`. +- Remote dispatch in `LexDispatch`: when a registered extension route's runner class is not loaded in the current process, the request is forwarded via AMQP — async (202) by default or sync (blocks on reply queue) when `X-Legion-Sync: true` header is present. Returns 403 when `definition[:remote_invocable] == false`. +- `Routes::Llm` and `Routes::Apollo` registration now guarded: skipped in `api.rb` when `Legion::LLM::Routes` / `Legion::Apollo::Routes` are already defined (i.e. self-registered by the library gem). + +### Changed +- `api.rb`: requires `api/library_routes` and `api/sync_dispatch`; LLM and Apollo route registration conditional on gem self-registration not already having run. + +## [1.6.23] - 2026-03-28 + +### Added +- `Legion::Extensions::Definitions` mixin: class-level `definition` DSL for method contracts (`desc`, `inputs`, `outputs`, `remote_invocable`, `mcp_exposed`, `idempotent`, `risk_tier`, `tags`, `requires`). Auto-extended onto every runner module at boot by the builder. +- `Legion::Extensions::Actors::Dsl` mixin: `define_dsl_accessor` generates class-level getter/setter DSL with inheritance and instance delegation. Wired into all actor base classes (`Every`, `Poll`, `Subscription`, `Once`, `Base`). +- `Absorbers::Base#absorb`: canonical entry point replacing `handle`. `alias handle absorb` preserves backward compatibility. + +### Changed +- `Builders::Runners#build_runner_list`: auto-extends `Legion::Extensions::Definitions` onto every discovered runner module unless it already responds to `:definition`. +- `Hooks::Base`: extended with `Definitions` mixin; `mount` DSL removed (paths fully derived from naming). +- `Absorbers::Base`: extended with `Definitions` mixin. +- `AbsorberDispatch`: calls `absorber.absorb` instead of `absorber.handle`. +- `Helpers::Lex`: all `function_*` helpers and `expose_as_mcp_tool`/`mcp_tool_prefix` marked `@deprecated` — use `definition` DSL instead. + +## [1.6.22] - 2026-03-27 + +### Added +- `POST /api/llm/inference` daemon endpoint: accepts a full messages array plus optional tool schemas, runs a single LLM completion pass, and returns `{ content, tool_calls, stop_reason, model, input_tokens, output_tokens }` — the client owns the tool execution loop +- `Legion::CLI::Chat::DaemonChat` adapter: drop-in replacement for the `RubyLLM::Chat` object that routes all inference through the daemon, executes tool calls locally, and loops until the LLM produces a final text response +- `spec/legion/api/llm_inference_spec.rb`: 12 examples covering the new `/api/llm/inference` endpoint +- `spec/legion/cli/chat/daemon_chat_spec.rb`: 25 examples covering `DaemonChat` initialization, tool registration, tool execution loop, streaming, and error handling + +### Changed +- `legion chat setup_connection`: replaced `Connection.ensure_llm` (local LLM boot) with a daemon availability check via `Legion::LLM::DaemonClient.available?` — **hard fails with a descriptive error if the daemon is not running** +- `legion chat create_chat`: now returns a `DaemonChat` instance instead of a direct `RubyLLM::Chat` object; all LLM calls route through the daemon + +## [1.6.21] -

2026-03-19 + +### Added +- GAIA cognitive layer as a core boot phase: `setup_gaia` runs between LLM and telemetry in the startup sequence +- Two-phase extension loading: all extensions are fully loaded (require + autobuild) before any actors are hooked (AMQP subscriptions, timers, etc.), preventing race conditions during boot +- `gaia: true` parameter on `Service.new` to control GAIA initialization +- GAIA graceful shutdown and reload support (shuts down before extensions, restarts after data) + +### Changed +- Boot order is now deterministic: Logging -> Settings -> Crypt -> Transport -> Cache -> Data -> RBAC -> LLM -> GAIA -> Telemetry -> Extensions -> API +- Extension actors are collected into `@pending_actors` during `load_extensions`, then started all at once via `hook_all_actors` + +## [1.4.69] -

`lex_const` now derives from `lex_class.to_s.split('::').last` so it returns the extension's root constant name (`Anchor`) rather than always returning the third element of the namespace array. +- `full_path` now builds the gem name from dash-joined segments (`lex-agentic-cognitive-anchor`) instead of underscore-joined `lex_name`, so `Gem::Specification.find_by_name` works for nested extensions. + +## [1.4.55] - 2026-03-17 + +### Changed +- `build_default_exchange` now sets `exchange_name` on dynamically created exchange classes to return `amqp_prefix` (dot-joined segments with `legion.` prefix) instead of defaulting to the parent class behavior +- `auto_create_exchange` now derives `exchange_name` from `amqp_prefix` + the exchange's own downcased class name, replacing the

`Service#default_paths` + +## [1.4.54] - 2026-03-17 + +### Changed +- `Helpers::Logger#log` now passes `lex_segments:` array to `Legion::Logging::Logger` when the object responds to `:segments` +- Falls back to `lex:` string for legacy flat extensions that do not implement `:segments` + +## [1.4.53] - 2026-03-17 + +### Fixed +- Extension discovery now correctly parses multi-hyphenated gem names

per request +- `GET/POST /api/tenants`: tenant listing and provisioning endpoints +- `POST /api/tenants/:id/suspend`: tenant suspension +- `GET /api/tenants/:id/quota/:resource`: quota check endpoint

2026-03-17 + +### Fixed +- `gem_load` rescue block referenced undefined `gem_path` variable, causing secondary NameError that masked original LoadError +- `meta_actors` type guard checked `is_a?(Array)` but called `each_value` (Hash method), so meta actors were never hooked +- `build_actor_list` crashed entire extension load when actor file didn't define expected constant (now skips gracefully) +- `build_transport` raised NoMethodError on extensions with custom Transport modules missing `build` (now falls back to auto-generate) + +## [1.4.46] - 2026-03-17 + +### Added +-

LegionIO

+ +

+ One Ruby gem that is a distributed async job engine, an AI coding assistant, an MCP server, + and a cognitive-computing platform — and runs with zero required infrastructure. +

+ +

+ Gem Version + Ruby + License + HA +

+ +``` + ╭──────────────────────────────────────╮ + │ L E G I O N I O │ + │ │ + │ async jobs · AI chat · MCP │ + │ REST API · HA · cognitive AI │ + │ zero-infra lite mode · Vault │ + ╰──────────────────────────────────────╯ +``` + +> Schedule tasks, chain services into dependency graphs, run them concurrently across a RabbitMQ +> fleet, and orchestrate AI-powered workflows — from a single `legion` command. Then run the whole +> thing with **no RabbitMQ, no Redis, nothing** via lite mode. + +## Why LegionIO + +- 🧩 **Four products in one gem.** A RabbitMQ-backed async **job engine**, an **AI coding assistant** (chat, commit, review, PR, multi-agent), an **MCP server** that exposes your infrastructure to any agent, and a brain-modeled **cognitive platform** — all in one `gem install`. +- 🪶 **Zero-infrastructure lite mode.** `LEGION_MODE=lite` swaps RabbitMQ for in-process pub/sub and Redis/Memcached for an in-memory cache. Every feature still works — `gem install` to a running daemon in seconds, no services to stand up. +- 🔗 **Dependency-graph orchestration.** Chain tasks with JSON conditions and ERB transformations, fan out in parallel, and scale by simply launching more processes — RabbitMQ distributes the work automatically (tested to 100+ workers). +- 🤖 **AI workflows built in.** `legion chat`, `commit`, `review`, `pr`, multi-agent `swarm`, persistent cross-session memory, and a shared knowledge store — powered by [legion-llm](https://github.com/LegionIO/legion-llm)'s any-client → any-provider routing. +- 🧠 **Cognitive architecture.** 240+ brain-modeled extensions across 18 domains (emotion, reasoning, social, metacognition…), coordinated by a tick-cycle scheduler ([legion-gaia](https://github.com/LegionIO/legion-gaia)). +- 🔌 **MCP-native.** Exposes itself as an MCP server (stdio or streamable HTTP), so Claude Desktop or any agent SDK can run tasks, manage extensions, and query your infrastructure directly. +- 🛡️ **Operational from day one.** Vault secrets, AES-256 message encryption, RBAC, JWT / API-key auth, sliding-window rate limiting, Prometheus metrics, an OpenAPI 3.1 spec, and live `SIGHUP` reload. **No paid tiers, no feature gates, full HA out of the box.** + +## The Legion Ecosystem + +LegionIO is the orchestrator; the heavy lifting lives in a family of focused, independently-versioned gems. Here's the one-line version — follow a link to dig in: + +| Gem | What it is | +|-----|-----------| +| [legion-llm](https://github.com/LegionIO/legion-llm) | Universal LLM proxy — any client dialect → any provider, with routing, escalation, and metering | +| [legion-gaia](https://github.com/LegionIO/legion-gaia) | Cognitive coordination layer — tick-cycle scheduler + weighted routing across cognitive modules | +| [legion-apollo](https://github.com/LegionIO/legion-apollo) | Shared + local knowledge store — RAG retrieval, embeddings, and a knowledge graph | +| [legion-data](https://github.com/LegionIO/legion-data) | Persistence — task history, scheduling, and chains over SQLite / PostgreSQL / MySQL | +| [legion-transport](https://github.com/LegionIO/legion-transport) | Messaging abstraction — RabbitMQ AMQP plus the in-process lite adapter | +| [legion-cache](https://github.com/LegionIO/legion-cache) | Caching abstraction — Redis / Memcached plus the in-memory lite adapter | +| [legion-crypt](https://github.com/LegionIO/legion-crypt) | Secrets & encryption — Vault integration, AES-256, JWT auth | +| [legion-rbac](https://github.com/LegionIO/legion-rbac) | Role-based access control with Vault-style flat policies | +| [legion-mcp](https://github.com/LegionIO/legion-mcp) | Model Context Protocol server/client implementation | +| [legion-settings](https://github.com/LegionIO/legion-settings) | Layered configuration + secret resolution (`vault://`, `env://`) | +| [legion-logging](https://github.com/LegionIO/legion-logging) | Structured logging used across every gem | +| [legion-tty](https://github.com/LegionIO/legion-tty) | Terminal UI components — spinners, tables, prompts | + +Capabilities (`lex-*` extensions) are a separate, much larger catalog — see [Extensions](#extensions) below. + +## What Does It Do? + +LegionIO routes work between services asynchronously. Tasks chain into dependency graphs with conditions and transformations controlling data flow: + +``` +Task A ──→ [condition] ──→ Task B ──→ [transform] ──→ Task C + └──→ Task D (parallel) + └──→ Task E ──→ Task F +``` + +When A completes, B runs. B triggers C, D, and E in parallel. Conditions gate execution. Transformations reshape payloads between steps. Add more workers by running more processes — RabbitMQ handles distribution automatically. + +But that's just the foundation. LegionIO is also: + +- **An AI coding assistant** — interactive chat with tools, code review, commit messages, PR generation, and multi-agent workflows +- **An MCP server** — 60 tools that let any AI agent run tasks, manage extensions, and query your infrastructure +- **A cognitive computing platform** — 242 brain-modeled extensions across 18 cognitive domains +- **A digital worker platform** — AI-as-labor with governance, risk tiers, and cost tracking + +## Quick Start + +```bash +gem install legionio +legionio check # verify subsystem connections +legionio start # start the daemon +``` + +For the AI features: + +```bash +legion # launch the interactive TTY shell +legion chat # interactive AI REPL with 40 built-in tools +legion commit # AI-generated commit message from staged changes +legion review # AI code review of your code +``` + +### Two Binaries + +| Binary | Purpose | +|--------|---------| +| `legion` | Interactive TTY shell + dev-workflow commands (`chat`, `commit`, `review`, `plan`, `memory`, `init`) | +| `legionio` | Daemon lifecycle + all operational commands (`start`, `stop`, `lex`, `task`, `config`, `mcp`, and 40+ more) | + +`legion` with no args drops into the interactive TTY shell. `legionio` is the full operational CLI. + +## Installation + +```bash +gem install legionio +``` + +Or add to your Gemfile: + +```ruby +gem 'legionio' +``` + +### Optional Capabilities + +| Gem | What It Unlocks | +|-----|-----------------| +| `legion-data` | Task history, scheduling, chains (SQLite/PostgreSQL/MySQL) | +| `legion-llm` | AI chat, commit, review, agents, multi-provider LLM routing | +| `legion-cache` | Redis/Memcached caching for extensions | +| `legion-crypt` | Vault integration, encryption, JWT auth | +| `legion-tty` | TTY UI components (spinners, tables, prompts) | + +## Zero-Infrastructure Mode (Lite) + +Run LegionIO without RabbitMQ, Redis, or Memcached: + +```bash +LEGION_MODE=lite legion start # environment variable +legion start --lite # CLI flag +``` + +In lite mode, `legion-transport` uses an in-process pub/sub adapter (no RabbitMQ required) and `legion-cache` uses a pure in-memory store with TTL (no Redis/Memcached required).

Actually quite well. The framework uses RabbitMQ to ensure jobs are scheduled and run in a FIFO order. As you add -more works, it just subscribes to the queues the workers can support and does more work. It is really geared towards a -docker/K8 type of environment however it can be run locally, on a VM, etc. - -As of right now, it has been tested to around 100 workers running in docker without any performance issues. You will -likely see performance issues on the DB or RabbitMQ side before Legion has issues. - -Another benefit is that you can run multiple LEXs in one worker or you could have dedicated workers that only run a single LEX. -In example if you have to make a ton of ssh connections via `lex-ssh`, maybe you want to run 10 pods with no other extensions in them -but then run a pod with `lex-pagerduty`, `lex-log` and `lex-http` to send out notifications after each ssh task is completed - -### High Availability -Because you can run this thing with multiple processes and it will distribute the work, it is naturally HA oriented. -if a worker goes down for some reason, another one should pick it up(assuming another work has that LEX enabled). There -are no hidden features, pay walls, etc to get HA. Just run more instances of LegionIO - -### Price and License -LegionIO is completely free. It was build using free time. There are no features held back, no private repos. -Everything is under an MIT license to keep it as open as possible. With that, the devs can't always help with support, -well because it's free. - -### Who is it geared for? -Anyone? Everyone? It could be used in a homelab to automate updating VMs. It could be used by someone to take ESPHome -sensor data and pipe it to influxdb. At least that is what @Esity does. It could also be used by a company or enterprise looking -to replace other tools. - -### But it is written in ruby -Yep. - -### Similiar projects -There are multiple projects that are similiar. Some things like IFTTT are great(but is it?) but then again, cost money. -* [Node-Red](https://nodered.org/) - No HA but has some good features and a great drag and drop interface -* [n8n.io](https://n8n.io/) - Working on HA but [not there yet](https://github.com/n8n-io/n8n/pull/1294) -* [StackStorm](https://stackstorm.com/) - Written in Python, has potential but I feel they are removing features to convince you to pay for it -* [Jenkins](https://www.jenkins.io/) - It's jenkins. I don't need to say anything else -* [Huginn]() - Another IFTTT style app written in ruby. Not sure on this one but it doesn't have HA from what I can tell [github issue](https://github.com/huginn/huginn/issues/2198) - -### Other fun facts -* Supports Hashicorp vault for storing secrets/settings/etc -* Can enable global message encryption so that all messages going through RMQ are encrypted with aes-256-cbc -* Each worker generates a private/public key that can be used for internode communication, it also will generate a cluster secret -for all nodes to have so they can share data accross the entire cluster.

+      runner_function (string), status (string: success/failure), input_tokens (integer),

+
+      Return ONLY a valid JSON object with these possible keys:
+      - "where": hash of column => value filters (e.g. {"status": "failure"})
+      - "order": column name to sort by (prefix with "-" for descending, e.g. "-cost_usd")
+      - "limit": integer limit (default 50)
+      - "date_from": ISO date string for recorded_at >= filter
+      - "date_to": ISO date string for recorded_at <= filter
+
+      For relative time references, compute ISO dates from the current date/time above:
+      - "today" => date_from is today's date at 00:00
+      - "last hour" => date_from is 1 hour ago
+      - "this week" => date_from is Monday of this week

+# Live Daemon Integration Tests
+
+Black-box HTTP tests against a running Legion daemon. No Legion code is loaded — just Faraday + RSpec using the parent LegionIO bundle.
+
+## Running
+
+Start the daemon first:
+```bash
+legionio start
+```
+
+Then run the suite from the LegionIO root:
+```bash
+bundle exec rspec --options spec/live/.rspec
+```
+
+To target a different host:
+```bash
+LEGION_API_URL=http://192.168.1.5:4567 bundle exec rspec --options spec/live/.rspec
+```
+
+## Adding specs
+
+Each spec file tests a logical API surface. Use the `get`/`post` helpers from `spec_helper.rb` — they handle JSON encoding/decoding and base URL resolution.
+
+## CI
+
+These specs are NOT included in the normal `bundle exec rspec` run and are excluded from GitHub Actions. They require a live daemon with real infrastructure (RabbitMQ, database, LLM providers, etc).
