Stacked on #1236 — retarget to develop after it merges.

Refs #1229. Ticket C of the page-free reads wave (exit criterion G8). Docs only; no src/ change.

What changed (file: lines on this branch)

Claim sweep: every place that said the credits read opens or uses the profile's browser now says it reads directly when the saved session is accepted, otherwise in the profile's browser.

File	Lines	Change
AGENTS.md	50	"Command surface" credits bullet
README.md	60	quick-start comment for gflow credits user
docs/MCP.md	130	gflow_get_credits entry only (direct read, fallback, 429/503 not falling back, link to CONFIGURATION). The gflow_auth_status entry is left to Ticket B
docs/USAGE.md	132–144	gflow credits: two requests and no browser, the fallback conditions, ProfileLockedError scoped to the browser read, 429/503 → exit 4/6 (credits list records it per profile), macOS/proxy defaults, kill switch
docs/USER_GUIDE.md	425–430	Journey 10.1
llms.txt	6–8	credits paragraph
skills/gflow-cli/SKILL.md + plugins/gflow/skills/gflow-cli/SKILL.md (regenerated)	64–66	credits comment, plus exit 4/6 = throttled, do not loop
KNOWN_ISSUES.md	948–956	#795 entry: the browser read is now the fallback, with a pointer to the new entry
docs/ARCHITECTURE.md	416	"Auth is the only browser interaction" now names the one exception
docs/ARCHITECTURE.md	420–443	new "Reads without a browser" section: placement (services/credits.py::_fetch_once, before FlowApiClient), what is sent and the rules in code, the fallback-reason enum, what raises instead of falling back (SecurityError, 429/503), per-profile per-process state, where it is off (macOS, proxy, kill switch), and that a FlowReader port arrives with its second consumer (#1194)
KNOWN_ISSUES.md	17–63	new Open entry, "The direct credits read uses the profile's saved Google session outside Chrome": the private-API account risk, rotation (stale snapshot accepted, session survived, from PR #1234), Set-Cookie dropped, the jar locked while Chrome runs on Windows → browser fallback, what is unmeasured (long-horizon staleness, at lifetime #1222, v20 encryption, Linux lock behaviour), remedy GFLOW_CLI_WIRE_READS=0
docs/E2E_TESTING.md	394	inventory row for tests/e2e/test_credits_wire_bdd.py
CHANGELOG.md	14–21	#1236's entry: rewrapped, "two HTTP requests" instead of "one page load", exit 4/6, pointer to KNOWN_ISSUES. No new entry
website/docs/*	same lines	regenerated mirror (ARCHITECTURE, E2E_TESTING, KNOWN_ISSUES, MCP, USAGE, USER_GUIDE)

Hits checked and left alone, because they are still true:

• docs/AUTHENTICATION.md:266: Chrome open on the profile → exit 11. The direct read falls back as store_unreadable and the browser read still reports it.
• docs/INDEX.md:164: "no 401 path". A wire 401 falls back and is never surfaced.
• docs/MCP.md:494: the comment "reads the balance from flow.google.com".
• PROJECT_STATUS history.

Claims I checked against code

• Where _signed_out is cleared: nowhere, and that is now documented. After a signed-out answer or a 401, that profile stays on the browser read until the process exits. This holds after a --refresh renewal too, so a long-running MCP server needs a restart.
• Throttle window: the Retry-After value is capped at 60 s by parse_retry_after, and the window is 60 s when Flow sends none. I left the number in CONFIGURATION.md only.
• Cookie counts: the spike measured 26 and the live proof sent 24, so I deliberately quote no count.

Follow-up

• docs/FLOW_WIRE_RPCS.md is not on develop yet (docs: Flow batchexecute RPC id table, checked against the served JavaScript #1219, unmerged). Once it lands, its "Read directly by" column needs nzlxg → api/flow_wire.py.
• The cookie spike doc is linked as PR docs(spike): cookie jar readability while Chrome runs and the cookies the wire needs #1234 rather than by file path until it merges.

Gates

All ten pass locally:

• hygiene, doc links, website PII, website mirror --check, council memory, plugin skills --check
• ruff check, ruff format, pyright
• pytest: 6172 passed, 12 skipped, coverage 93%

No Flow surface is touched (docs only), so no e2e run applies.

Summary by CodeRabbit

• New Features
  • Credit-balance checks can read directly from a saved session without opening a browser when Flow accepts it.
  • If the direct read is unavailable, gflow can use the profile’s browser, subject to platform and configuration settings.
• Documentation
  • Updated usage guides to explain browser fallback, throttling behavior, and how to force browser-based reads.

Walkthrough

Documentation now describes direct credits reads when Flow accepts a profile’s saved session, and browser reads otherwise. It records configuration, fallback and throttling behavior, architecture details, and related test coverage.

Changes: Credits read documentation

Layer / File(s)	Summary
Direct-read flow and architecture docs/ARCHITECTURE.md, website/docs/ARCHITECTURE.md	The architecture documentation describes the direct request flow, cookie and token handling, fallback and error cases, per-profile state, and conditions that disable direct reads.
Credits command guidance AGENTS.md, README.md, docs/USAGE.md, docs/MCP.md, docs/USER_GUIDE.md, llms.txt, skills/gflow-cli/SKILL.md, plugins/gflow/skills/gflow-cli/SKILL.md, website/docs/USAGE.md, website/docs/MCP.md, website/docs/USER_GUIDE.md	Command and user guidance describes direct reads when Flow accepts the saved session, browser reads otherwise, and settings and throttling outcomes.
Release notes, issue records, and test maps CHANGELOG.md, KNOWN_ISSUES.md, docs/E2E_TESTING.md, website/docs/KNOWN_ISSUES.md, website/docs/E2E_TESTING.md	The changelog and issue records describe direct-read behavior and limitations. The E2E file maps identify coverage for browserless reads and fallback behavior.

Merge Risk: Low · previous review 62403

The updated guidance can misstate when a browser opens, how locked profiles and throttling behave, and how long a read can take. Some website links also fail. These are bounded documentation risks.

Inline comments:
Review comments at @CHANGELOG.md:
- Line 17: Clarify the credits error outcomes in the known-issues entry:
distinguish `credits user`, which exits 4 or 6 on HTTP 429 or 503, from `credits
list`, which records the error for the affected profile and preserves partial
results; make the same clarification in the website mirror.
- Around line 15-16: Update the changelog’s “When that fails” fallback
description to state that if an open Chrome profile causes a ProfileLockedError,
the user must close Chrome and retry; preserve the existing browser fallback
guidance for other failures.

Review comments at @docs/ARCHITECTURE.md:
- Line 430: Update the deadline description in the architecture documentation to
distinguish the five-second network deadline from the separate five-second
cookie-extraction limit used by read_credits. Do not describe five seconds as
the overall deadline, since the two stages can together take nearly ten seconds
before fallback.

Review comments at @docs/USAGE.md:
- Line 136: Update the browser-fallback documentation in the usage guide to
describe that an open Chrome window on Windows can lock the cookie store,
causing a ProfileLockedError and preventing balance retrieval; tell users to
close Chrome and retry. Apply the same documentation change to the website
mirror.

Review comments at @docs/USER_GUIDE.md:
- Around line 425-430: Clarify the Veo credit-balance description so macOS users
understand that the direct read is disabled by default, not the browser read.
Update the wording around the direct-read and browser fallback, retain the
existing issue and configuration references, and regenerate the website mirror
from the corrected user guide.

Review comments at @README.md:
- Line 60: Update the `gflow credits user` guidance and matching agent and MCP
guidance to qualify the browser-free claim: an accepted saved session avoids
browser use only when direct reading is enabled and available. Preserve the
existing note that checking the balance spends nothing.

Review comments at @website/docs/ARCHITECTURE.md:
- Line 442: Update the “Ports & adapters” link in the “No port yet” paragraph to
use the MkDocs anchor #ports-adapters so it navigates correctly on the website,
while preserving the canonical GitHub anchor.
- Line 440: Update the website mirror generator’s link rewriting so references
to the root KNOWN_ISSUES.md resolve to the sibling website page, preserving any
fragment or query suffix; regenerate the affected website mirrors.

Qualify the browser-free claim.

An accepted session does not guarantee a direct read. On macOS by default, or when a proxy is configured, gflow uses the browser even for a valid session. (raw.githubusercontent.com)

State that the direct read must also be enabled and available. Update the same unconditional claim in the agent and MCP guidance.

Verified, fixed in 37c39a0: the browser-free read needs wire_reads on (off by default on macOS, and skipped behind any proxy, api/flow_wire.py). README and the AGENTS.md command-surface bullet now say "when the direct read is on and the saved session is accepted". docs/MCP.md and llms.txt already link CONFIGURATION for the conditions, so they are unchanged.

@ffroliva Thanks. I confirmed the updates to README.md and AGENTS.md in 37c39a0. I understand the decision to leave the linked MCP and llms.txt guidance unchanged.

Both skill files still describe an accepted session as sufficient for a browser-free read. The agent-guidance part of the finding remains open.

### Reading a generation's status or file opens a browser page; a page-free path is measured but not built

**Caveats before building on it:** the shell's `at` (`SNlM0e`) is missing whenever Flow
serves the signed-out page, meaning the cookies were not accepted (#1221). A page-free
reader must treat that as an auth problem and fall back to the page. Cookie
lifetime without a running browser is unmeasured. An account served `labs.google` could not
be observed here. Full write-up:
[`docs/superpowers/spikes/2026-11-09-page-free-reads.md`](docs/superpowers/spikes/2026-11-09-page-free-reads.md).

## Testing instructions — The Impeccable Routine

- Documentation is a first-class deliverable. Every behavior, workflow, config, or operator-facing change must update the relevant docs or state why no docs changed in the PR/checklist. `scripts/ci/check_doc_links.py` is a merge gate.
