qmaster 0.1.0

Personal value-for-fit hardware deal-hunter: filters, values, and ranks classifieds/retail listings into a digest (search + compare; human-approved bidding is a later phase).

Quartermaster

· MIT · Python 3.13+ · a personal project, provided as-is (issues welcome, no support guarantee)

Codename: Quartermaster · repo quartermaster · Acquisitions, rationed.

A personal agent that finds the best value-for-fit RAM (and later: any fitment-gated hardware) across EU classifieds + multi-retailer price data, and ranks it by live landed cost vs the market -- so you see the best deal available now. Buying stays in your hands: a one-click-approved Gixen auction snipe within a hard budget is a later phase (Phase 2).

Status (2026-06-28): Public + MIT. Phase-1 pipeline runnable end-to-end (fitment -> valuation/ECB-FX -> live/bootstrap baseline -> deal% -> ranked digest), with provider-agnostic email input (file / stdin / IMAP; Gmail optional). 212 tests green. Phase 1 = SEARCH + COMPARE; bid/buy is Phase 2 (Gate 0: eBay API dropped). See DECISIONS.md.

Quickstart

Requires Python 3.13+. It is not on PyPI -- install from this repo. (The unrelated quartermaster package on PyPI is not this project; don't pip install quartermaster.)

# zero-install run (uv fetches Python 3.13 for you) against the bundled sample:
uvx --from git+https://github.com/Wombat164/quartermaster.git quartermaster examples/sample-alert.eml

# or put the CLI on PATH:
uv tool install git+https://github.com/Wombat164/quartermaster.git
quartermaster examples/sample-alert.eml              # bundled sample  ->  a ranked digest
quartermaster path/to/your/alerts/*.eml              # your own .eml / .txt files
cat alert.eml | QM_MAIL_SOURCE=stdin quartermaster   # or pipe one in

(pipx install --python 3.13 git+..., or pip install git+https://github.com/Wombat164/quartermaster.git inside a 3.13 venv, also work.)

Runs alert-only with zero accounts or keys (deterministic regex extraction + a bootstrap price table). Opt in to more, each independent and off by default:

Want	Set	Adds
LLM extraction (messy free-text listings)	QM_ANTHROPIC_API_KEY	Claude extraction (else regex-only)
Live market comps (real deal %)	QM_SERPAPI_API_KEY	SerpApi baseline (else a bootstrap table)
Live email from any provider	QM_MAIL_SOURCE=imap + QM_IMAP_* + an app-password	stdlib IMAP -- Gmail / Outlook / Fastmail / Proton / self-hosted
Gmail via OAuth (rarely needed)	the [gmail] extra (uv tool install "quartermaster[gmail] @ git+https://github.com/Wombat164/quartermaster.git") + QM_MAIL_SOURCE=gmail	the Gmail API (caveats -- 7-day token, full-mailbox scope)

Secrets come from your env / secret store (e.g. export QM_SERPAPI_API_KEY=$(bw get password serpapi)), never committed; QM_DRY_RUN defaults true. Copy .env.example to .env to configure.

Gate 0 RESOLVED (2026-06-26) -- pivot to search + compare

Deep-research (docs/background/ebay-gate0-research.md) found production eBay Buy/Browse API access is partner-only, business-model-gated, "no guarantee", with no personal-app precedent -- too uncertain to build on. So the eBay API is dropped:

• Phase 1 (now): SEARCH + COMPARE on compliant sources -- classifieds saved-search alert EMAILS (discovery) + SerpApi Google Shopping as the compare baseline (retail / Amazon / eBay-as-price-comps, no scraping) + a bootstrap EUR/GB table. No approve button.
• Phase 2 (deferred): BID/BUY -- manual eBay + a Gixen snipe with one-click approval. The money/safety machinery (ledger/FSM/source-tag) is already built + tested in v0 increment 2.

The non-negotiables (compliance & safety — hard-coded)

1. Human one-click approval before every binding bid (eBay's Feb-2026 UA bans autonomous order flows). Gixen still fires the pre-approved max unattended at close.
2. eBay content is processed deterministically — never sent to an LLM; raw eBay content purged < 6 h; immutable source tag enforced by test.
3. No scraping. Classifieds = native saved-search alert EMAILS only (the email body is the dataset; no re-resolve/fetch). Images excluded from the LLM path.
4. EU-only auto-bid; fail-closed kill-switch + DRY_RUN default-true; arming real money needs two independent signals.
5. Reserved-budget ledger with a release path (Σ live max-bids ≤ cap, released on every terminal state).

Configuration & secrets

Config is separate from the program (12-factor). Everything runtime-tunable is an env var prefixed QM_ (or a gitignored .env) -- copy .env.example to .env to start. Secrets are SecretStr and live in your secret store, injected via env -- never committed:

export QM_SERPAPI_API_KEY="$(bw get password serpapi)"   # e.g. Bitwarden

QM_DRY_RUN defaults to true (fail-safe). Model: src/quartermaster/config.py; full security posture: SECURITY.md.

Tech

Python 3.13 · uv · stdlib email/imaplib email input · httpx · Claude structured outputs + a dependency-light injection guard (llm-guard pluggable) · ECB FX via currencyconverter · SQLAlchemy 2 + Alembic · structlog (secret-redacted) + healthchecks.io · respx · GitHub Actions (ruff / mypy-strict / pytest + hypothesis / bandit / pip-audit / gitleaks; actions SHA-pinned). Phase-2 (bidding) adds the Gixen + reserved-budget-ledger machinery already built in v0.
