[Unreleased]

Fixed

• BREAKING (security CRITICAL): Jira webhook handler is now fail-closed (issue #83). Previously, if JIRA_WEBHOOK_SECRET was unset, _verify_signature returned True and any unauthenticated POST to /webhooks/jira could trigger the full ingest pipeline. The handler now returns 503 when the secret is missing (operator-misconfiguration signal, distinct from 401 wrong-signature). Operators relying on the no-secret = accept-everything mode (don't — it was never documented) must set JIRA_WEBHOOK_SECRET before this merges.
• Security (CRITICAL): Jira issue keys arriving via webhooks are now validated against the canonical ^[A-Z][A-Z0-9]{0,31}-[0-9]{1,12}\Z format ([0-9] not \d to refuse non-ASCII Unicode digits, \Z not $ to refuse trailing newlines that $ would tolerate) before any filesystem operation (issue #83). Previously, issue_key flowed unsanitized into connectors/jira/service.py (save_issue, download_attachment, _handle_deletion, process_webhook_event) and connectors/jira/incremental_transform.py, enabling path traversal (../../etc/passwd style writes outside the Jira data dir). New module connectors/jira/validation.py provides is_valid_issue_key (regex whitelist; underscore deliberately excluded — Atlassian rejects underscores in real project keys) and safe_join_under (Path.resolve() containment check). Both are enforced at every filesystem boundary, defense-in-depth.
• Security (CRITICAL): webhookEvent (the second attacker-controlled field in Jira webhook payloads) was used as a filename component in _log_webhook_event without sanitization (issue #83 reviewer follow-up). A payload with webhookEvent: "../../tmp/pwn" could write a JSON dump outside WEBHOOK_LOG_DIR. The handler now strips everything that isn't [A-Za-z0-9_-] (dot deliberately excluded to defeat .. survival), clips length to 64 chars, and routes the final filename through safe_join_under.

[0.11.5] — 2026-04-27

Follow-up release for PR #73: addresses four rounds of Devin AI review on the role-management-complete branch. No new public-API surface; the user-visible payoff is that v8→v9-migrated installations now work end-to-end (login flows, user list, admin nav, privilege revocation), and make local-dev startup is finally quiet.

Fixed

• Privilege retention after grant revocation via the new REST API (Devin review #73). _hydrate_legacy_role previously short-circuited on a truthy user.get("role"). The role-management endpoints (POST/DELETE /api/admin/users/{id}/role-grants, plus the changeCoreRole UI flow) only mutate user_role_grants — they don't touch the legacy users.role column. After a downgrade-via-API, the stale legacy value would keep user["role"] = "admin" in memory; _is_admin_user_dict and the catalog/sync admin-bypass short-circuits then silently retained elevated table access even though require_internal_role correctly denied the API gates. Fix: always re-resolve from user_role_grants regardless of the legacy column, making the grants table the single source of truth on every authenticated request. Cost: one DB round-trip per request (same as the existing PAT-aware fallback).
• Dev-bypass + OAuth callback dropped direct grants from the session cache (Devin review #73). Both call sites passed external_groups only to resolve_internal_roles, never the user's id — so user_role_grants rows were resolved on the per-request DB-fallback path inside require_internal_role instead of the cache. Functionally correct, but every admin-gated request paid a DB round-trip and the dev-bypass log line read "resolved 0 internal role(s)" for an obviously-admin user, which was confusing during debugging. Fix: pass user_id so the cache reflects the union at sign-in.
• GET /api/users returned HTTP 500 for any v8→v9-migrated installation. The migration NULL-s legacy users.role (kept as a deprecated artifact because DuckDB FK blocks DROP COLUMN), but UserResponse.role is a required str Pydantic field — every user listing failed validation. /admin/users showed only "Failed to load users" and the new /admin/users/{id} Detail link was unreachable. Fix: route every user dict returned by the API through _hydrate_legacy_role (same shim already used by get_current_user), which derives the legacy enum value from user_role_grants for migrated users. Also fixes a quieter dual of the same bug — target["role"] == "admin" short-circuits in update_user/delete_user would silently no-op on migrated admins, letting the operator demote/delete the last admin against the documented protection.
• Scheduler log-noise: every cron tick produced a POST /auth/token 401 Unauthorized access-log line because the scheduler's auto-fetch fallback was always broken — it called /auth/token with just an email, but the endpoint requires email + password. Fix: removed the auto-fetch path entirely. Operators set SCHEDULER_API_TOKEN (a long-lived PAT) in production; in LOCAL_DEV_MODE the dev-bypass auto-authenticates the un-tokenized request, so jobs continue to work.
• HTTP 500 on POST /auth/token for v8-migrated users (Devin review #73 round 3). TokenResponse.role is a required str Pydantic field, but the v8→v9 migration NULL-s the legacy users.role column for every existing user. The login endpoint passed the raw NULL through to Pydantic, raising ValidationError → 500. Same root cause produced semantically wrong (but non-crashing) JWTs from Google OAuth, password, and email-magic-link flows — they wrote role: null into the issued token; downstream _hydrate_legacy_role in get_current_user would correct the per-request view, but the token payload itself stayed misleading. Fix: hydrate inline in each login flow before reading user["role"] — app/auth/router.py (POST /auth/token), app/auth/providers/google.py (OAuth callback), app/auth/providers/password.py (5 flows: JSON login, web login, JSON setup, web reset, web setup), and app/auth/providers/email.py (centralized in _consume_token, covers both magic-link /verify endpoints). New regression class TestAuthLoginFlowsPostMigration in tests/test_schema_v9_migration.py pins both the no-crash and the correct-role contracts for all four legacy levels (viewer/analyst/km_admin/admin).
• docs/RBAC.md documented an implies=[…] keyword on register_internal_role() that the function doesn't accept (Devin review #73 round 3). A module author copying the example would hit TypeError: got an unexpected keyword argument 'implies' at import time. Reality: implies is currently seeded only for the core.* hierarchy via _seed_core_roles in src/db.py — the registry-side write path doesn't exist yet. Rewrote the Implies hierarchy and Module-author workflow sections to document what's actually supported in 0.11.4 and what a future change would need to add.
• _seed_core_roles was advertised as a per-connect safety net but only ran during fresh installs and the v8→v9 migration (Devin review #73 round 4). The docstring promised "called from _ensure_schema on every connect" so an accidental DELETE FROM internal_roles WHERE key = 'core.admin' (or a doc-tweak release that updated _CORE_ROLES_SEED without bumping the schema version) would self-heal on the next process start. In reality both call sites lived inside if current < SCHEMA_VERSION: — once the DB was on v9, the seed function never ran again, leaving any deletion permanent and any in-code display_name/description/implies change requiring a manual SQL deploy. Fix: added an unconditional tail call to _seed_core_roles(conn) at the bottom of _ensure_schema, gated only by current <= SCHEMA_VERSION so the future-version-rollback contract still holds. New regression class TestSeedCoreRolesSafetyNet in tests/test_schema_v9_migration.py pins all three contracts (deleted row re-seeds, mutated display_name re-syncs from code, applied_at doesn't churn on already-current DBs).
• make local-dev startup spammed an AuthlibDeprecationWarning from upstream's own _joserfc_helpers.py every time app/auth/providers/google.py triggered the from authlib.integrations.starlette_client import OAuth import chain. The warning is upstream-internal — authlib telling itself to migrate from authlib.jose to joserfc before its 2.0 cut — and isn't actionable on our side until either authlib ships the fix or we rewrite OAuth on top of joserfc directly. Filtered the specific warning class at the top of app/main.py (with a message-based fallback if the class moves in a future authlib release) so the warning no longer pollutes operator-facing stdout. Other DeprecationWarnings remain visible.

Added

• /profile now self-services every user's role situation. Three new sections rendered server-side for all signed-in users (not just admins): Effective roles (the full resolver output as chip cloud — direct grants ∪ group-derived ∪ implies-expanded), Direct grants (rows in user_role_grants with source label: auto-seed from v8 backfill vs. direct admin grant), and Roles via groups (which Cloud Identity / dev group grants which role for the current user). Non-admins finally see why a particular feature is or isn't accessible without asking an admin to read the DB. Admins additionally see a deep-link to /admin/users/{id} for editing their own grants in place.
• /admin/role-mapping group ID picker. A new "Known groups" panel above the create-mapping form surfaces clickable chips of group IDs known to the system: the calling admin's own session.google_groups (with human-readable names + a "your group" tag) merged with distinct external_group_ids already used in existing mappings (tagged "already mapped"). Click a chip → fills the form's external-group-id input and focuses the role select. Empty-state copy points the operator at LOCAL_DEV_GROUPS / Google sign-in when the picker is empty, instead of leaving them to guess Cloud Identity opaque IDs from memory.

Changed

• Renamed docs/internal-roles.md → docs/RBAC.md. Standard industry term, more discoverable for engineers grepping for "RBAC" in a new repo. Added Quickstart-by-role sections (operator / end-user / module author) and a step-by-step Module-author workflow with code examples for registering a key, gating endpoints, declaring implies hierarchies, and writing a contract test against the gate. Cross-references in code (app/api/admin.py, tests/test_role_resolver.py) updated. CLAUDE.md now points contributors at the new doc from the Extensibility → RBAC section. Historical CHANGELOG entries ([0.11.3] / [0.11.4] body) keep the original internal-roles.md filename — they describe what shipped at that version and aren't retro-edited.

[0.11.4] — 2026-04-27

Role-management complete release. Sjednocuje legacy users.role enum (viewer/analyst/km_admin/admin) with the v8 internal-roles foundation under one model with implies hierarchy, ships admin UI + REST API + CLI for managing both group mappings and direct user grants, and wires require_internal_role for PAT-aware resolution so admin endpoints work uniformly across OAuth and headless callers.

Added

• Schema v9 — unified role model. New user_role_grants(user_id, internal_role_id, granted_by, source) table for direct user→role assignments (complementary to group_mappings which assigns via Cloud Identity group). Two new columns on internal_roles: implies (JSON array of role keys this role transitively grants) and is_core (BOOL, distinguishes seeded core.* hierarchy from module-registered roles). Migration v8→v9 seeds four core.* rows (core.viewer/analyst/km_admin/admin) with the legacy hierarchy as implies (core.admin → core.km_admin → core.analyst → core.viewer), backfills one user_role_grants row per existing user mirroring their pre-v9 users.role value (source='auto-seed'), and NULLs the legacy column.
• PAT-aware require_internal_role. Two-path resolution: session cache first (OAuth flow), DB-backed user_role_grants fallback (PAT/headless flow). Admin CLI scripts now hit gated endpoints uniformly without an OAuth round-trip. The PAT-specific 403 message from 0.11.3 is removed — PAT now legitimately resolves through direct grants.
• Implies expansion at resolve time. New expand_implies(role_keys, conn) helper in app.auth.role_resolver does BFS over the implies graph; resolve_internal_roles calls it at the end so a single core.admin grant expands to the full four-level hierarchy automatically.
• Dotted role-key namespace. Regex extended to allow core.admin, context_engineering.admin, corporate_memory.curator style keys (max 64 chars, lower-snake-case segments separated by dots). The owner_module column should match the prefix before the first dot.
• REST API for role management. New router app/api/role_management.py under /api/admin: GET/POST/DELETE on group-mappings, users/{id}/role-grants, plus GET internal-roles and GET users/{id}/effective-roles (debug). All gated by require_internal_role("core.admin") — works for both OAuth admins (cookie) and admin PATs.
• Admin UI /admin/role-mapping. Browse internal roles, manage Cloud Identity group → role mappings (table view + create/delete forms). User detail page extended with three sections: Core role (single-select for core.*), Additional capabilities (multi-checkbox for module roles), Effective roles (debug view of direct + group-derived + expanded set).
• da admin CLI subcommands. role list, role show <key>, mapping list/create/delete, grant-role <email> <key>, revoke-role <email> <key>, effective-roles <email>. All run over PAT — use them in CI scripts to grant/revoke roles without going through the browser.

Changed

• BREAKING (semantics, not API). users.role column NULL-ed during v8→v9 migration. Reads via UserRepository.get_by_* still return the column but the value is always NULL after upgrade — code reading user["role"] directly in business logic gets None. The legacy Role enum (Role.VIEWER/ANALYST/KM_ADMIN/ADMIN) and convenience helpers (is_admin, has_role, etc. in src/rbac.py) continue to work — they now read from user_role_grants via the resolver. Sweeping user.get("role") == "admin" checks were rewritten to the new helper. The column itself is preserved physically because DuckDB rejects DROP COLUMN while a FK references the table; physical drop is deferred to a future schema-rebuild migration.
• require_role(Role.X) and require_admin are now thin wrappers over require_internal_role(f"core.{role}"). Behavior identical for OAuth users (admin role from group_mappings); PAT users now succeed when they hold a direct core.admin grant.
• UserRepository.create() and update() mirror role changes into user_role_grants automatically (_grant_core_role helper); existing setup code keeps working without changes.
• UserRepository.delete() pre-deletes user_role_grants rows (DuckDB FK doesn't auto-cascade).
• UserRepository.count_admins() reads user_role_grants ⨝ internal_roles WHERE key='core.admin' — the legacy users.role = 'admin' count would always return 0 after backfill.
• app/api/admin.py module-level docstring documents the v9 pattern for module authors who want to add their own capability gates.
• docs/internal-roles.md rewritten to remove the v8 "no UI yet" caveat, document the implies hierarchy, the dual session/DB resolution pathway, and the dotted-namespace key convention.

Removed

• require_internal_role's session-only enforcement (the v8 "This endpoint needs an interactive (OAuth) session — Bearer/PAT tokens do not carry session-resolved roles" error message). PAT clients with a matching user_role_grants row now pass the gate uniformly.

Internal

• New UserRoleGrantsRepository in src/repositories/user_role_grants.py mirrors the style of GroupMappingsRepository (list/get/create/delete + per-user / per-role indices).
• INFO-level audit log on grant + mapping mutations (action strings: role_mapping.created/deleted, role_grant.created/deleted, resource mapping:<id> / grant:<id>).
• "Last admin protection" on DELETE /api/admin/users/{id}/role-grants/{grant_id}: refuses to delete the final core.admin grant in the system (mirrors existing count_admins protection on user deletion / deactivation).

0.11.3 — 2026-04-26

Authorization-foundation release — adds the internal-roles layer between Cloud Identity groups and per-module capability checks. Schema v8 migration; no admin UI yet (follow-up).

Added

• Internal roles + group mapping (foundation). Schema v8 adds two tables: internal_roles (app-defined capabilities like context_admin, agent_operator, registered by Agnes modules at import time) and group_mappings (many-to-many bindings of Cloud Identity group IDs to internal role keys, managed by admins). New app.auth.role_resolver module exposes register_internal_role(...) for module authors, sync_registered_roles_to_db(...) (run once at startup, idempotent), resolve_internal_roles(external_groups, conn) (called at sign-in, writes resolved keys into session["internal_roles"]), and a require_internal_role("…") FastAPI dependency factory for permission checks. Resolution runs at sign-in (Google OAuth callback + dev-bypass — populates on first request and whenever external groups change, mirroring the OAuth callback's always-write semantics). No DB hit per request. Refresh requires re-login, same semantics as session.google_groups. No admin UI yet — mapping rows must be created via the repository directly until the management UI ships in a follow-up. PAT/headless clients carry no session and therefore cannot pass require_internal_role gates by design — require_internal_role distinguishes "signed-in but missing role" from "no session at all" and surfaces a PAT-specific 403 detail in the second case so an API consumer hitting the wall sees what to fix. See docs/internal-roles.md → PAT and headless requests.

Changed

• docs/internal-roles.md documents Admin → Users → deactivate then reactivate as the supported "force re-resolve now" lever for users you can't get to log out (long-lived sessions, automated clients) — invalidates the existing session and forces a fresh sign-in on the next request.

Internal

• INFO-level audit log on every successful resolve (OAuth callback + dev-bypass) so a "wrong role" complaint is debuggable from the log alone — admin can correlate "user X claims they lost access" with the resolver output without replaying the request.
• Startup warning when SESSION_SECRET is shorter than 32 chars, matching the existing JWT_SECRET_KEY gate. Both HMAC surfaces sign trust-laden state (session.internal_roles, session.google_groups, JWTs) — keeping the two gates consistent so a weak secret gets surfaced at boot, not after a quiet downgrade.
• _clear_registry_for_tests() now refuses to run unless TESTING=1 so a stray import path in production can't drop the registered capabilities.

0.11.2 — 2026-04-26

Dev-experience patch release — make LOCAL_DEV_MODE realistic enough to actually exercise group-aware code paths on localhost, and consolidate scattered dev-onboarding instructions into a single docs/local-development.md.

Added

• LOCAL_DEV_GROUPS env var mocks session.google_groups for the auto-logged-in dev user when LOCAL_DEV_MODE=1. JSON array matching the production shape ([{"id":"…","name":"…"}]) so group-aware UI and access-control code paths can be exercised on localhost without a Google OAuth round-trip. Honored only under LOCAL_DEV_MODE=1. The startup banner reports the parsed group IDs (or warns loudly when the value is set but malformed), so a typo gets surfaced at boot rather than silently on the first authenticated request. Session injection mirrors the production OAuth callback's "always-write" semantics — including clearing stale groups when the operator unsets LOCAL_DEV_GROUPS mid-session. See docs/auth-groups.md → Local-dev mock.
• make local-dev now seeds two default mocked groups (Local Dev Engineers + Local Dev Admins on example.com) via scripts/run-local-dev.sh, so first-boot /profile is non-empty out of the box. Override with LOCAL_DEV_GROUPS='[…]' make local-dev; disable with LOCAL_DEV_GROUPS= make local-dev.
• docs/local-development.md — single onboarding doc for working on Agnes locally: TL;DR, what LOCAL_DEV_MODE actually bypasses, group mocking, what isn't mocked, and the security-rails reminder that dev mode must never reach a production deploy.

Internal

• Fix nightly docker-e2e CI failures: refresh two stale assertions that had drifted from the live API. tests/test_docker_full.py::test_app_returns_html_on_root now expects the auth-aware 302 → /login (root has redirected since the auth middleware landed); tests/test_e2e_docker.py::TestDockerHealth::test_health_has_duckdb now reads services["duckdb_state"] (current health-payload shape, already validated by tests/test_api.py). No application behavior change — these only ran in the scheduled nightly job, so the drift went unnoticed for several PRs.

0.11.1 — 2026-04-26

Patch release — hotfix the missed Caddy env passthrough that should have shipped with 0.11.0, plus codify changelog discipline so this kind of drift gets caught at PR review time next time.

Fixed

• docker-compose.yml caddy service now passes CADDY_TLS through to the container (- CADDY_TLS bare-form passthrough). Without it the Caddyfile {$CADDY_TLS:default} substitution always falls back to cert-file mode regardless of what the operator wrote into .env, and Caddy crash-loops on Let's Encrypt / internal-CA deployments. Should have shipped with #52; first attempt was #55, accidentally closed before merging.

Internal

• CLAUDE.md — non-negotiable changelog discipline: every PR touching user-visible behavior must update CHANGELOG.md under ## [Unreleased] in the same PR.

0.11.0 — 2026-04-26

First tagged semver release. The version = "2.x" strings that appeared in earlier pyproject.toml snapshots were arbitrary placeholders from the initial scaffold and never reflected actual API maturity — resetting to pre-1.0 to signal that things may still shift.

Added — Auth

• Google Workspace groups on /profile. OAuth callback fetches the signed-in user's group memberships via Cloud Identity (searchTransitiveGroups with the security label — see docs/auth-groups.md for the GCP setup checklist and the security-vs-discussion_forum gotcha). Profile link added to the user dropdown.
• Password reset + invite flows for web and admin (/auth/password/reset, /admin/users/invite).
• Personal access tokens (PAT) with separate :typ=pat JWT claim, per-token revoke, last-used IP tracking, "My tokens" + admin "All tokens" UI.
• Email magic-link provider (itsdangerous-signed token).
• Optional SEED_ADMIN_PASSWORD to pre-hash the seed admin (dev convenience).

Added — Deploy

• keboola-deploy.yml workflow. Tag-triggered alternative to release.yml for shared dev VMs that want explicit "deploy when I tag" semantics. Publishes immutable :keboola-deploy-<tag> + floating :keboola-deploy-latest alias.
• Caddy + Let's Encrypt + corporate-CA TLS. Caddyfile parametrized via $CADDY_TLS env var so a single file serves three regimes: cert-file (corp PKI), Let's Encrypt auto-issue, Caddy-internal-CA. URL-driven cert rotation with self-signed fallback (scripts/grpn/agnes-tls-rotate.sh). docker-compose.tls.yml overlay closes host :8000 when Caddy fronts.
• dev_instances schema in customer-instance Terraform module gains optional tls_mode + domain (mirrors prod_instance). infra-v1.6.0 tag.
• Optional Google OAuth credentials from Secret Manager. Module reads google-oauth-client-{id,secret} at boot if present; graceful fallback so non-Google deployments aren't affected.
• LOCAL_DEV_MODE + make local-dev-up / local-dev-down for one-keystroke local stack with magic-link auth pre-wired.
• Per-developer dev-<prefix>-latest GHCR alias for branches matching <prefix>/<branch> — push-to-deploy on personal dev VMs.
• /setup web wizard for first-time instance setup, plus headless POST /api/admin/configure and POST /api/admin/discover-and-register.
• Smoke-test job in CI (Docker-in-CI after every release) + scripts/smoke-test.sh for post-deploy verification.

Added — CLI

• Wheel distribution + auto-update check on startup.
• --version flag, --dry-run + X/N progress on da sync, durable sync (atomic writes + manifest hash + retry on transient errors).
• gzip on JSON/HTML responses (server-side).

Added — Data

• Remote query engine. Two-phase BigQuery + DuckDB engine for tables too large to sync locally (--register-bq flag).
• Business metrics. Standardized metric_definitions table in DuckDB with starter pack importer (da metrics import).
• /api/health returns version, channel, commit_sha, image_tag, schema_version.
• Custom connector mount support (connectors/custom/).
• OpenAPI snapshot test for breaking-change detection.

Added — Docs / tooling

• docs/auth-groups.md, docs/DEPLOYMENT.md, docs/HACKATHON.md, docs/ONBOARDING.md runbooks.
• scripts/debug/probe_google_groups.py — stdlib-only probe for diagnosing Cloud Identity API issues without a deploy cycle.
• Schema migration safety tests (idempotency, data preservation, snapshot).
• Pre-migration snapshot of system.duckdb before schema upgrades.
• Auto-generated JWT and session secrets with file persistence (/data/state/.jwt_secret).
• Startup banner logging version, channel, and schema version.

Changed

• BREAKING (deployment) — Caddy compose profile renamed production → tls. Existing docker compose --profile production up -d invocations need to switch.
• BREAKING (deployment) — Default Caddyfile mode is now cert-file (tls /certs/fullchain.pem /certs/privkey.pem); for the previous Let's Encrypt auto-issue behaviour set CADDY_TLS=tls <ops-email> in .env. See docs/auth-groups.md and Caddyfile inline docs.
• Schema migration v5→v6→v7: adds users.active, personal_access_tokens table, personal_access_tokens.last_used_ip. Auto-applied at boot.
• Image-level AGNES_VERSION now sourced from pyproject.toml at build time (no more drift between da --version and the package metadata).
• Vendor-agnostic OSS rule codified in CLAUDE.md — customer-specific names, hostnames, project IDs belong in consumer infra repos, not in this OSS distribution.

Fixed — Security

• Open-redirect guard for backslash in safe_next_path.
• SessionMiddleware max_age=3600 + https_only (was browser-session forever, plain-HTTP-OK).
• Timezone-aware datetimes in Keboola metadata cache.
• Atomic magic-link token consumption (closes double-use race under concurrent clicks).
• Bootstrap backdoor closed when passwordless seed admin exists.
• urllib3 1.26→2.6.3 (resolves 4 Dependabot security alerts).
• argon2-cffi adopted for password hashing.
• See docs/padak-security.md for the full audit.

Fixed — Other

• uvicorn --proxy-headers --forwarded-allow-ips='*' so OAuth callbacks resolve to https when behind a TLS terminator.
• scripts/grpn/agnes-tls-rotate.sh hardened: --max-redirs 0 + --proto '=https' on cert fetch, post-fetch PEM validation (rejects HTML error pages from corp portals), ulimit -c 0 to suppress coredumps that could leak the unencrypted privkey, POSIX-safe ${arr[@]+"${arr[@]}"} array expansion.
• scripts/tls-fetch.sh — generic URL fetcher (sm://, gs://, https://, file://) with redirect refusal + PEM validation.
• kbcstorage moved to optional dep — unblocks urllib3 security updates; primary Keboola path now uses the DuckDB Keboola extension.
• Dependencies consolidated into pyproject.toml (no more requirements.txt).

Internal

• Test suite expanded to 1357+ tests (4 layers — unit, integration, web smoke, journey).
