HVBrowser

HVBrowser provides browser automation APIs for HentaiVerse. It builds on hbrowser for the shared authenticated browser session.

The package was extracted from the historical combined hbrowser distribution. Battle-domain APIs live in the separate hvbattle package. HVBrowser 0.1.4 requires hbrowser>=0.35.2,<0.36; version 0.35.2 is the minimum release that provides the optional process-log API used when the calling application has no external output supervisor.

Lottery and Monster Lab APIs

Lottery inspection is read-only and returns the current ticket count, shared GP balance, and the fixed 1,000 GP ticket price. Purchasing requires an explicit lottery kind and positive quantity, then verifies the exact ticket increase and GP decrease before returning:

from hvbrowser import LotteryClient, LotteryKind

client = LotteryClient(driver)
snapshot = await client.inspect(LotteryKind.WEAPON)
report = await client.purchase(
    LotteryKind.WEAPON,
    25,
    expected_before=snapshot,
)

The optional snapshot is an optimistic precondition: if tickets, GP, lottery kind, or price changed after planning, the client raises before touching the purchase form.

Target counts, Weapon-versus-Armor priority, and behavior when GP is limited are application policy and intentionally do not belong in this package. The legacy HVDriver.loetterycheck() spelling remains as a compatibility wrapper.

Monster Lab exposes the two known feed-all resources explicitly:

from hvbrowser import MonsterLabClient, MonsterLabFeed

client = MonsterLabClient(driver)
snapshot = await client.inspect()
food_report = await client.feed_all(MonsterLabFeed.FOOD)
drugs_report = await client.feed_all(MonsterLabFeed.DRUGS)

After the Monster Lab API is confirmed, an action image that is not present is reported as unavailable and produces no mutation. The selector and post-submission disappearance semantics still require a read-only live selector check and a separately authorized mutation check, respectively. Missing page structure, unknown submission outcomes, and unstable/failed post-submit confirmation raise typed errors. Both purchase and feed-all calls change account state; automated package tests use only offline fakes.

Lottery, Monster Lab, and Repair navigation share a fail-closed maintenance guard. One atomic DOM snapshot classifies timed challenge, final-completion, next-floor, and active-battle markers. Any such marker raises MaintenanceNavigationBlockedError before Bazaar interaction; its typed blocker field is a MaintenanceNavigationBlocker value. A Persistent post-battle client is allowed one initial navigation away from its own positively completed battle; the landing page is classified before any Bazaar interaction. Every retry and Repair navigation classifies the current page first, and every navigation is classified again after it completes.

When no battle marker is present, a Bazaar selector timeout or missing element allows exactly one same-realm homepage retry. A second miss fails, and non-timeout errors are never retried. No Lottery purchase or Monster Lab submission is attempted during this navigation recovery. Repair captures the current realm before its fallback and reloads only that realm: Isekai uses goisekai(), while Persistent uses gohomepage(force=True).

Development

Build a clean environment backed by the PyPI release of hbrowser:

bash scripts/rebuild-env.sh

For coordinated local development, overlay the clean environment manually:

uv pip install --python .venv/bin/python --reinstall --no-deps --editable \
  /Users/kuanlun_wang/Desktop/git-repo/hbrowser.clone

Commands that must preserve this editable overlay use uv run --no-sync.

Read-only Market inspection

Market inspection and sale planning are non-mutating by default:

import asyncio

from hvbrowser import HVDriver, SellItems


async def main() -> None:
    async with HVDriver(headless=True) as driver:
        snapshot = await driver.inspect_market()
        plan = await driver.marketcheck(SellItems(materials=["Low-Grade Metals"]))
        print(len(snapshot.items), plan.total_units)


asyncio.run(main())

The compatibility marketcheck() call requires commit=True before it can request submission. Submission is currently blocked by a fail-closed runtime gate until the current quote selector and pricing semantics have been confirmed with the read-only live probe. The guarded implementation never deposits credits and never re-lists unrelated orders.

Guarded live smoke test

The surrounding hentaiverse workspace owns account selection. This smoke probe only refuses to construct a browser unless credentials are supplied indirectly through the environment. It stops when an active battle is detected and contains no state-changing purchase, feed-all, submit, repair, recovery, or battle call. It does use navigation clicks to reach the requested read-only pages:

uv run --no-sync python scripts/live_readonly_smoke.py \
  --skip-market \
  --inspect-lotteries \
  --inspect-monster-lab

--skip-market lets the two new selectors be checked independently while the Market integration is unavailable. The last two flags only inspect counts and action availability. They never call the Lottery purchase form or do_feed_all. When the current realm is Isekai, Lottery and Monster Lab are reported as unavailable and skipped without navigating to Persistent.
