Flags were natively supported in Rust (the hanzo-flags crate — the evaluation
core, pub-exported for Rust callers and FFI-exported for the rest), Go (in-process
via CGO to that core), and TypeScript (@hanzo/flags over /v1/flags). Python was the
gap. This closes it.
hanzo-flags POSTs an evaluation context to cloud /v1/flags — the same
PostHog-compatible endpoint every other client speaks — and answers is_enabled /
variant / payload from the response. It mirrors @hanzo/flags exactly: a HanzoFlags
client bound to one host, load(distinct_id, person_properties=, groups=), the same
three-field result, an async twin, and a one-shot evaluate().
Two invariants match the family: fail-open (a transport error yields the last good
or empty result with errors_while_computing set, never a raise on the hot path)
and cache-by-context+TTL. Zero runtime dependencies — stdlib urllib only, so a
flag check never drags httpx/pydantic into a service.
Tests stand up a local /v1/flags stub and prove the request shape is
PostHog-compatible, the accessors resolve booleans/variants/payloads, the TTL
cache holds, and both a 5xx and an unreachable host fail open. 7/7 green.
Hand-written package for the engine /v1/training API: ServiceClient +
TrainingClient (create/list/get/delete/forward_backward/optim_step/
sample/save_weights), dataclasses, sync httpx, completed-future
.result() wrapper so tinker fut.result() code ports 1:1. 22 pytest
tests over httpx.MockTransport, no network.
Wired like siblings: publish-pypi hanzo-train-* tag case, rye+uv
workspace member, uv source, pyright exclude. uv.lock relock also
catches the lockfile up to on-disk truth (hanzoai 3.1.1,
hanzo-tools-browser 0.5.10) -- no package versions changed.
zap.py is an httpx.BaseTransport; httpx is not a base dep (client core is urllib3).
3.1.0 imported zap.py eagerly in __init__, so `import hanzoai` crashed on missing
httpx in any clean install. Guard the import (try/except ImportError) and declare
httpx under the [zap] extra. import hanzoai now works with or without extras.
Add hanzoai.zap: an httpx.BaseTransport / AsyncBaseTransport that routes the
SAME typed client calls through hanzo_zap.CloudClient over the ZAP binary wire.
Opt in with Hanzo(http_client=hanzoai.zap_http_client(...)); default stays HTTPS.
- hanzo-zap is an optional extra [zap], imported lazily so "import hanzoai"
still works when it (and zap-proto) are not installed.
- Public __all__ is byte-identical; new names are additive and kept out of __all__.
- Request to ZAP mapping: path to dotted method, api-key header to Bearer auth,
body forwarded verbatim.
- Tests: back-compat lock + request-translation via mock CloudClient (no network).

The uv workspace listed only 10 of 61 packages as members, so `uv sync`
never installed fs/shell/agent/reasoning/lsp/refactor/todo/jupyter/memory —
and hanzo-tools-core's integration suite (which asserts each imports with an
exact TOOLS count) failed 20 tests against the absent packages. Add the 9
required tool packages as members + [tool.uv.sources] workspace pins so the
real toolset installs and the suite validates live code. Honest fix — install
what the test asserts, don't weaken the assertions. Suite: 24 passed / 12
skipped (was 20 failed / 4 passed). Lock resolves clean (tree-sitter, tornado,
nbformat added). No regressions: hanzoai 3/3, browser 11/11, hanzo-mcp boots.
hanzo-tools-core was a [tool.uv.sources] gap: not a workspace member, so uv
resolved it from PyPI 0.3.0 — the OLD package that still ships the duplicate
hanzo_tools/core/ WITHOUT ToolImage, shadowing canonical hanzo-tools.core and
breaking 'from hanzo_tools.core import ToolImage' (browser tests: 6 fail/5 error).
Add hanzo-tools + hanzo-tools-core as workspace members AND [tool.uv.sources]
= { workspace = true } so both resolve on-disk (0.3.1 empty shim), never the
shadowing wheel. Purge the stale untracked pkg/hanzo-tools-core/hanzo_tools/
build artifact. Finishes the decomplect 711eb498 started. Browser tests: 11/11 green.
#45 regenerated hanzoai as a pure OpenAPI client and DELETED the hand-written
core-SDK modules (config/mcp/session/protocols/…) that live in the same package
but aren't part of API generation. hanzo-mcp imports all four → the published
hanzoai 3.0.0 crashed EVERY hanzo-mcp consumer on startup ('No module named
hanzoai.protocols') → the MCP server wouldn't boot → agent couldn't
reconnect. Restore the 4 self-contained modules hanzo-mcp needs (verified: zero
imports of the removed Stainless internals); they coexist with the generated
api/models client. Left agents/auth/cluster/llm_client OUT — they import the
removed ._client and need migration to the new client (separate follow-up, no
reconnect-path consumer). Bump 3.0.0→3.0.1. Boot-proven: hanzo-mcp starts,
26 tool packages / 29 tools, MCP initialize OK.
Patch release carrying the HIP-0111 IAM endpoint migration in
hanzoai.resources.iam (/iam/api/get-account + /iam/api/userinfo ->
canonical /v1/iam/oauth/userinfo), already in-tree since be917695 but
unreleased. 2.2.1 is taken on PyPI; bump to 2.2.2 (x.x.x+1).
Closes the last gap in the one-way Hanzo control surface. IAM/KMS/PaaS
already had both CLI subcommands and MCP tools; S3 had neither.
- hanzo s3: buckets/mb/rb/ls/stat/rm/presign over hanzo_s3 (MinIO) client,
creds from env (inject from KMS, never plaintext). Registered in the
unified hanzo CLI alongside iam/kms/paas.
- hanzo-tools-s3: S3Tool MCP tool (same action-dispatch pattern as PaaSTool),
exported via the hanzo.tools entry point; s3 added to loader prefix map.
- uv workspace: map hanzo-cli/iam/kms/s3 + tools-s3 to local sources so the
unified CLI resolves on-disk packages (fixes hanzo_iam ImportError from a
stale published 1.29.0 wheel shadowing local 1.30.0).
Tests: 7 CLI + 14 MCP, all green.
* fix(browser-mcp): migrate CDP bridge -> zapd consumer; make disk authoritative
The MCP runtime kept pulling the buggy published wheel (hanzo-tools-browser
0.5.7) from PyPI instead of the migrated on-disk source, so every restart
re-broke the `cdp` tool. Reinstate `cdp` as a zapd-native tool, finish the
bridge->zapd migration (delete dead bridge/server modules + their tests), bump
to 0.5.8 and pin hanzo-mcp >=0.5.8, add the package to the uv workspace/sources
so disk is authoritative. 9/9 browser tests pass.
Pairs with the hanzoai/extension bridge->zapd migration (separate, still
uncommitted). The ~/.claude.json MCP invocation was also pointed at the local
editable source (machine config, not in this repo).
(cherry picked from commit 11b4d4ea8a5570d6fb0e51079fa445dba3713f71)
* fix(browser): drop dead lifecycle.py (in-process zap_server/cdp_bridge are gone)
lifecycle.py only wrapped the removed in-process ZAP server + CDP bridge; nothing
imports it under the zapd-consumer model. One way: transport is zapd_consumer,
tools are browser/cdp/playwright.

protocols.py landed 2026-03-31 (200cef23) but 2.2.0 was published before
it, so the module never reached PyPI. hanzo-mcp imports
hanzoai.protocols at startup; resolving against the published 2.2.0
crashed every stdio launch with ModuleNotFoundError before the
initialize response — surfacing as 'Failed to connect' in Claude
Desktop/Code.
Add hanzo-tools-ui to workspace members and hanzo-mcp dependencies so
the ui tool is actually discoverable at runtime. Add LocalUIClient that
reads components directly from ~/work/hanzo/ui when available, falling
back to GitHub API. Adds list_packages and read_file actions. Fixes
GitHub config components_path to match actual repo layout (pkg/ui/primitives).
Subpackages have their own type checking. The previous exclude list was
incomplete, leaving 65 pyright errors from hanzo-tools-* packages.

Strict mode with 22+ disabled report types is contradictory and has caused
CI to never pass (0/50 runs). Basic mode is the honest configuration for
an SDK with many optional dependencies and generated code.

target-version, and mypy python_version to 3.12. Remove 3.9/3.10/3.11
from CI test matrix, keep 3.12 and 3.13.
