Refs #1229. Ticket A of the page-free reads wave. The plan is in docs/superpowers/plans/2026-11-10-flow-reader/ on docs/flow-reader-wave (GOAL, PREDICT CAUTION, SCENARIO rows 1–30, PLAN A1–A10).

What changed

gflow credits user, gflow credits list and MCP gflow_get_credits now read the balance without starting Chrome when the profile's saved session is accepted. The read uses the profile's own cookies, one GET of https://flow.google.com/ (for at, f.sid and bl), and one batchexecute POST of nzlxg, parsed by the existing CreditsInfo.from_nzlxg.

• Most failures fall back to today's browser read, unchanged.
• HTTP 429/503 (row 29, as amended in the review round) raise the page path's own RateLimitError/NetworkError and open a per-profile window (Retry-After, else 60 s). Inside it every read of that profile re-raises with nothing sent and no browser built; after it the wire is tried again. 500/502/504 fall back as http_error and disable nothing.

File	Change
api/flow_wire.py (new)	Plain functions, WireFallbackReason (StrEnum) and WireReadUnavailable(reason). No Protocol and no reader class. Rpcid allow-list {nzlxg}; follow_redirects=False; connect 3 s, overall deadline 5 s; no retry on 4xx; one retry on connect error only. Single-flight per-profile at cache under an asyncio.Lock, re-checked under the lock. All state is per profile: token cache, lock, signed-out set (signed_out_shell/401), throttle window. A reject-all cookie jar drops Set-Cookie. The cookie read runs in asyncio.to_thread. UA comes from the profile's own Last Version (Chrome major). Signed-out is detected only by a missing SNlM0e, never by size.
services/credits.py::_fetch_once	Wire first, before FlowApiClient is constructed (it launches Chrome on entry). Logs credits.read source=wire|page, plus credits.wire_fallback reason=<enum> (and error_type only, for an unexpected exception).
auth/cookies.py::read_cookies_for	GFLOW_CLI_HOME boundary check first. Explicit cookie_file, plus key_file on win32 (None there would read the user's own Chrome key). RFC 6265 domain match for flow.google.com (path /, unexpired). Every failure becomes CookieStoreUnreadable(<class name>). Never the Playwright fallback. Never browser_cookie3's VSS shadow copy: a pre-open of the jar fails while Chrome holds it, and the shadow-copy method is removed for the call.
data/redaction.py	Adds __Secure-1/3PAPISID, SIDCC, NID, AEC, form at= and f.sid=. The cookie rule no longer fires on f.sid.
config.py + .env.template + docs/CONFIGURATION.md + website mirror	GFLOW_CLI_WIRE_READS (bool). Default on, except on darwin.
cli_credits.py help, gflow_get_credits description=, CHANGELOG [Unreleased]	Claims updated. The wider doc sweep (MCP.md, USAGE, USER_GUIDE, SKILL, llms.txt, KNOWN_ISSUES, ARCHITECTURE) is Ticket C.
tests/conftest.py	The offline suite defaults the wire off in _no_outbound_network; e2e/live are exempt.

Mirror axes (check step 1b): no new CLI option, no MCP param, no queued payload key. The only MCP change is the description=. The MCP door has its own live test (below).

Not in this PR: row 25 (doctor / gflow_auth_status wire health) belongs to Ticket B.

Red → green (TDD)

The tests were written first, against interface-only stubs, and each failure was read to confirm it failed for the right reason. That run gave 76 failed, 12 passed:

• 49 NotImplementedError (wire and cookie read not built)
• 3 AttributeError: 'Settings' object has no attribute 'wire_reads'
• the redaction test ('fake1papisid' not in …)
• service and BDD assertions: assert [] == ['signed_out_shell'], DID NOT RAISE SecurityError, assert 11 == 42 (page ran instead of wire)

Rows 29–30 were added later and went red first as well: 13 failed, 59 passed. The causes were WireReadUnavailable: http_error where RateLimitError/NetworkError was expected, the missing credits.wire_rpc_error event, and DID NOT RAISE RateLimitError in the service.

Ablation: I removed the reject-all jar and the under-lock disable re-check. The jar test failed ([2] == [0]) and both concurrency tests failed (5 == 1). The header-only Set-Cookie test still passed, so the jar test is the one that proves row 13.

Gates: all ten pass. Offline suite: 6161 passed, 30 skipped, coverage 93%. pyright: 0 errors.

Live proof on denon82 ($0, browser-session lease held, GFLOW_CLI_DEBUG_TRACEBACK=1, per-run stdout/stderr kept)

G1: cold gflow credits user --profile denon82 --json, 5 separate processes, every run source=wire, exit 0, integer balance. p50 1.83 s (min 1.62, max 2.38). The floor, a cold gflow credits --help, is 0.74–0.86 s.

24 cookies were sent: domain-matched, path /, unexpired.

G7: one run with GFLOW_CLI_WIRE_READS=0 printed credits.read source=page, exited 0 and returned an integer balance in 38.53 s. That run includes the #1140 close timeout.

8 passed, 3 warnings in 671.28s

The page-path tests logged browser_teardown.force_close_returned and "Future exception was never retrieved"; both are #1140/#1233 teardown.

UnexpectedError: 0 occurrences across all live runs, with stderr captured every time.

The cookie-free arm replaces flow_wire.read_cookies_for with lambda _p: [] inside the e2e test only. There is no production hook, and the real jar is untouched.

Deviations from PLAN.md, with reasons

• read_cookies_for returns (name, value) pairs, not a dict. _ga_* sits on both flow.google.com and .flow.google.com, and a browser sends both.
• The enum has more reasons than the seven in G3:
  • http_error: other 4xx such as 403/404
  • disabled: the wire is off for this process
  • unexpected: raised only in the service, with the class name logged
• Import time (A4): flow_wire itself imports no Playwright. Importing it loads gflow_cli.api/__init__.py, which eagerly imports FlowApiClient and therefore Playwright (-X importtime: 57 playwright rows). services/credits.py already imported FlowApiClient before this change. Making the package init lazy touches every importer, so it is left out of this ticket.
• NetworkError (5xx) carries no retry_after. The class has no such field, and I did not invent one.

Observations

• Packaging test flake. tests/data/test_packaging.py::test_built_distributions_contain_sql_migrations failed once under -n 8 (a uv build sdist error). It passed alone and in the next full run, and this PR does not touch packaging.

Review round (two fresh xhigh reviews; one fix round)

SCENARIO row 29 now reads: 429 and 503 raise RateLimitError / NetworkError and open a per-profile window (Retry-After, capped 60 s, 60 s when absent). Every read of that profile inside it re-raises with the remaining time, sends nothing and builds no page; after it the wire is tried again. 500/502/504 fall back as http_error and disable nothing.

Summary by CodeRabbit

• New Features
  • Credit balances can be read directly from Flow using a saved session, without starting a browser. This is enabled by default on Windows and Linux, and disabled by default on macOS.
  • Direct reads can be controlled with GFLOW_CLI_WIRE_READS and are skipped when a browser proxy is configured.
• Improvements
  • Ordinary direct-read failures fall back to the browser. Rate-limited requests are reported without browser fallback, with retries paused during the cooldown.
  • Sensitive session details are better protected in error messages and request logs.
• Documentation
  • Configuration guides explain the direct-read setting and its behavior.

Walkthrough

The change adds an optional direct Flow credits read using saved profile cookies. The credits service uses the browser when a direct read is unavailable, while rate-limit and network errors are surfaced. The change also adds configuration, credential redaction, logger settings, and related tests.

Merge Risk: Low · previous review 9fa6b

Direct reads may use an environment proxy even when the browser does not, and the documentation omits the 60-second throttle cap. These bounded concerns warrant owner follow-up but do not currently block merging.

src/gflow_cli/__init__.py: 1

3-13: Trivial · Maintainability & Code Quality · Low value

Import-time logger clamp is acceptable, but the new import logging conflicts with the repository guideline.

The guideline says "never raw print() or import logging in src/." The import is private (_logging) and is needed to configure third-party stdlib loggers. structlog cannot clamp httpx and httpcore. The behavior is correct and holds for the CLI, the MCP server and the daemon.

Add a short comment that this is an intentional exception, so reviewers do not remove it or flag it again. Consider an explicit allowance in docs/AGENT_GUIDE.md.

The test name does not match what it checks.

test_ordinary_words_ending_in_at_are_not_redacted uses format=json data=ok. These words end in at and ta. The lookbehind (?<![\w.]) prevents the match. The test is valid.

Add a case for a bare at= field with an unrelated prefix, such as chat=1, to confirm the boundary.

Reuse fresh_wire. Add a public reset helper in flow_wire.

This fixture resets four private attributes of flow_wire. The same four-line reset is copied into these places:

• tests/services/test_credits_wire_fallback.py: _wire_on
• tests/e2e/test_credits_mcp_e2e.py: _fresh_wire
• tests/e2e/test_credits_wire_bdd.py: ctx
• tests/features/test_credits_wire_steps.py: ctx

If someone adds a new per-process state container to flow_wire, every copy must change. A missed copy leaks state between tests, so tests become order-dependent.

Add a reset_state() function to flow_wire. Have this fixture call it. Replace the copies with the fresh_wire fixture. This also removes the cross-module reach into private names.

As per coding guidelines, src/gflow_cli/**: "Cross-module communication goes through public interfaces, never private internals."

The test may pass without proving the clamp works.

The test relies on MCPServer(name="probe") raising the root logger to INFO. The code read does not show this. If MCPServer does not configure logging, caplog.set_level(logging.DEBUG) still sets the root level. Then httpx logs at INFO only if its own level permits. The clamp sets the httpx logger to WARNING, so the test passes in both cases.

caplog.set_level(logging.DEBUG) without a logger argument sets only the root level. The final loop asserts the effective level, which is the real check. Another test or fixture can change httpx logger levels. Another test can also import gflow_cli earlier, so the import gflow_cli at Line 23 can be a no-op.

Add a negative control. Reset the httpx logger to NOTSET, confirm the URL is logged, then re-import or re-apply the clamp. This shows the test detects a regression.

Accepted, fixed in 6df3adf. The test now runs a negative control first: with the httpx logger reset to NOTSET the fake f.sid does reach the captured log, then the clamp is restored and the same request leaves no trace in caplog or stderr. So it detects a regression.

@ffroliva Thanks for adding the negative control. I checked commit 6df3adf4.

One part of the finding remains: the test restores the existing httpx logger level, but it does not run the production clamp again if gflow_cli was already imported. If another test set the logger to WARNING, this test could pass even if the production clamp were removed.

Please exercise package initialization in a fresh subprocess, or re-run initialization and restore the logger state afterward.

CodeRabbit review-body nitpicks: all three accepted and fixed in 6df3adf.

1. src/gflow_cli/__init__.py logger clamp: added a comment saying the stdlib-logging touch is a deliberate exception to the structlog-only rule, because it configures third-party loggers (httpx, httpcore) and does not log.
2. tests/data/test_redaction.py: added the chat=1 boundary case. chat=1 at=AFAKE keeps chat=1 and redacts only the at= value.
3. tests/conftest.py reset blocks: added a public flow_wire.reset_state(). The shared fresh_wire fixture and the two e2e fixtures call it instead of setting private attributes, and the duplicated blocks in the service and BDD tests are gone (they use fresh_wire).
