docs(spike): cookie jar readability while Chrome runs and the cookies the wire needs by ffroliva · Pull Request #1234 · ffroliva/gflow-cli

ffroliva · 2026-11-10T12:52:37Z

Spike for the page-free reads wave. It cost $0: shell GETs and free nzlxg balance reads only, run on denon82. The script's readings were pre-registered in its docstring and committed before run 1.

Q1: with no Chrome running, the profile jar alone gives a working wire read. The controls behaved as expected: no cookies gives a signed-out shell and a 401; a junk at gives a 400. Backward elimination found a 4-cookie minimal set: OSID (flow.google.com), SID, __Secure-1PSIDTS and __Secure-3PSID. The current labs.google filter in _is_flow_cookie keeps none of them.
Q2: while Chrome runs, the jar cannot be read. Open, sqlite (including immutable=1) and copy all fail with a sharing violation (WinError 32). browser_cookie3 surfaces this as RequiresAdminError from its shadow-copy fallback, but the cause is the lock, not DPAPI.
Q3/Q4: Chrome rotates 7 session cookies, and a snapshot taken before it opened is still accepted afterwards. The browser session survives, so no STOP condition was met. Run 1 is marked contaminated because another agent's e2e suite was using the profile; run 2 and a replay reproduced the result with the profile held on its own.
Q5: all 62 Google cookie values are v10; there are no v20 values.
Wire responses: every one sets *SIDCC cookies.
Open lead: right after run 2, 2 browser-backed credits user reads exited 1 with UnexpectedError. The failure did not reproduce on replay (0/3), and the 7 reads after it all passed. The cause is unmeasured.

Files: scripts/dev/spike_cookie_jar_wire.py, docs/superpowers/spikes/2026-11-10-cookie-jar-and-wire-cookies.md. Doc-only plus a dev script; no Flow surface changes, so no e2e applies.

Summary by CodeRabbit

Documentation
- Added a report summarizing observed browser-session behavior, authentication outcomes, and study limitations, including results from cookie-access and page-free read trials.
Chores
- Added a developer-only diagnostic experiment that compares session state and records test results without storing cookie or token values. It includes controls for browser-open and browser-closed conditions and limits the number of read trials.

Walkthrough

This pull request adds a read-only experiment for profile-cookie access and page-free Flow balance reads. It records cookie inventories, request outcomes, Chrome-open access probes, and stale- and fresh-snapshot results. A spike report documents the observations and limitations.

Changes: Cookie-Jar Wire-Read Experiment

Layer / File(s)	Summary
Cookie inventory and wire requests `scripts/dev/spike_cookie_jar_wire.py`	Defines experiment questions and adds cookie inventory, metadata, and Flow shell and balance request helpers.
Q1 and Chrome-open probes `scripts/dev/spike_cookie_jar_wire.py`	Adds cookie controls and ablation, probes cookie-database access methods, and tests a wire read during the Chrome-open phase.
Experiment orchestration and findings `scripts/dev/spike_cookie_jar_wire.py`, `docs/superpowers/spikes/2026-11-10-cookie-jar-and-wire-cookies.md`	Runs leased experiment phases, compares cookie snapshots, and documents observed outcomes and limitations.

Merge Risk: Low · up to c2ac0

This adds a read-only spike script and a report and does not change the product. A few documentation inaccuracies remain, and the redaction of one error-output field may be incomplete. Both are narrow, so the change is mergeable with minor follow-up.

- Line 82: Reconcile the count in the account-cookie inventory row with its
listed cookie names and the recorded inventory: update the count or the names so
they agree with the inventory.
- Line 109: Update the “Minimal set found” claim to either verify each cookie’s
necessity by removing it in turn from the final four-cookie set and confirming
the flow fails, or describe the set as sufficient without claiming minimality.
- Line 235: Update the conclusion in the “wire” results section to distinguish
the ten rows with timestamp changes from the eight rows with changed values in
the sendable set; do not imply that all ten rows had changed values.
- Around line 251-252: Revise the “Rotation on wire reads” statement to limit
the claim to responses that actually set the three SIDCC cookies; identify those
observed responses and make clear that the no-cookie arm reports only NID. Do
not describe every wire response as setting them.

Review comments at @scripts/dev/spike_cookie_jar_wire.py:
- Line 467: Update disk_probes to wrap the build_client phase in try/finally and
remove OUT_DIR / "cookie_copy" in the finally block, so copied cookie data is

- Line 432: Update the browser_cookie3_subprocess assignment to pass the stderr
fallback through redact() before recording it; ensure redact() covers local
paths on the platforms where this script runs, while leaving the stdout value
unchanged.

Verify minimality against the final set.

The one-pass elimination tests each retained cookie before later cookies are removed. It does not establish that removing a retained cookie from the final set would fail. Test each of the four removals from the final set, or describe the set as sufficient rather than minimal.

Fixed in bf19ca4: it now says this is a minimal set found by one-pass elimination. Each cookie failed when dropped from the larger set remaining at its turn, but whether each is necessary against the final set was not tested. The set is shown to be sufficient because it passed alone. The __Secure-1PSID remark is weakened to match.

Length of output: 59454

@ffroliva Thanks for clarifying the test results. The new caveat makes the evidence clear.

The report still calls the set minimal at Line 109, and the pre-registered reading at Line 31 makes the same claim. The final-set removals were not tested.

Could you call it a sufficient set found by one-pass elimination and annotate the pre-registered minimality claim as unverified? Alternatively, test each removal from the final set.

If you found this review helpful, would you consider giving us a shout-out on X?

CodeRabbit review-body findings, triaged. Review 5842195079 says only "Actionable comments posted: 6": it has no nitpick or outside-diff section, and all six inline findings are already answered in their threads. The walkthrough summary adds one more item:

Finding	Decision
Pre-merge warning: docstring coverage 16.67% < 80% on `scripts/dev/spike_cookie_jar_wire.py`	DECLINE: the project enforces no docstring rule (ruff selects E/F/W/I/B/UP/N/T20/S, no D). The file is a throwaway dev spike script under `scripts/dev/`; its module docstring holds the pre-registered readings, which is what the spike protocol requires.
Summary's "before merging" items (leftover cookie copy on failure, stderr redaction, inconsistent report claims)	Already covered: these restate inline findings 4525133292 to 4525133361, which are answered in their threads.

Minor · Functional Correctness · Quick win

Mark the inventory as partial or include the missing domains.

Line 73 reports 75 cookies, but this table lists 42. Q1 asks which cookies the jar holds for each domain, so readers can mistake this table for the complete inventory. Include the missing domain groups, or label the table as partial and state that it omits 33 cookies.
