# Alpha Status

Portlight is in alpha. This document describes what is complete, what is being tuned, and what players should expect.

## What is complete

Every core system is implemented, tested, and stress-verified:

- **Economy** — scarcity-driven pricing across 10 ports, 8 goods, 17 routes. Flood penalty, market shocks, provenance tracking.
- **Voyages** — multi-day travel with storms, pirates, inspections, provisions, hull, and crew.
- **Captain identity** — three archetypes (merchant, smuggler, navigator) with 8-20% pricing gaps and distinct access profiles.
- **Contracts** — six families with trust/standing gates, provenance-validated delivery, deadline tracking, and board effects.
- **Reputation** — regional standing, customs heat, commercial trust, port standing. Multi-axis access model.
- **Infrastructure** — warehouses (3 tiers), broker offices (2 tiers across 3 regions), 5 licenses. Real upkeep with closure on default.
- **Insurance** — hull, cargo, and contract guarantee policies. Heat surcharges, coverage caps, denial conditions.
- **Credit** — 3 tiers with interest accrual, payment deadlines, default consequences (3 defaults freeze line).
- **Campaign** — 27 milestones across 6 families, career profile interpretation (7 tags with confidence levels), 4 victory paths with met/missing/blocked diagnostics.
- **Save/load** — full compound state round-trip (economy + contracts + infrastructure + insurance + credit + campaign).

## Verification

- **609 tests** across 24 test files
- **14 cross-system invariants** (laws that must hold under any game state)
- **9 compound stress scenarios** — debt spiral, warehouse neglect, insured luxury loss, contract expiry under pressure, heat/license conflict, legitimization pivot, oceanic overextension, victory-then-stress, save/load mid-crisis
- **Balance harness** — 7 policy bots, 7 scenario packs, 3 captain types, structured report generation

All stress scenarios pass with zero invariant violations. The game never produces negative silver, duplicate contract outcomes, or corrupted campaign state under compound pressure.

## What the balance harness currently shows

From the most recent 105-run simulation (mixed_volatility scenario, all policies, all captains):

**Captain parity:**
- Navigator reaches brigantine fastest (day 11)
- Merchant reaches brigantine by day 20
- Smuggler does not reach brigantine in current tuning
- Merchant leads in net worth at day 40 (12,396 silver)
- Smuggler leads overall net worth (13,985) via high-margin luxury trades

**Route concentration:**
- Porto Novo / Silva Bay dominates 31% of all traffic
- Mediterranean is over-concentrated; West Africa and East Indies are under-explored by policy bots

**Contracts:**
- Zero contracts completed across all automated runs (delivery logic gap in policy bots, not in the contract engine itself)
- Contract board generates offers correctly; the gap is in bot strategy, not game mechanics

**Insurance:**
- Zero insurance adoption across all automated runs
- Policies are available and functional; bots don't evaluate risk well enough to purchase

**Victory paths:**
- Shadow Network is the strongest candidate (28% of runs reach candidacy)
- Oceanic Reach appears for 10% of navigator runs
- Lawful Trade House and Commercial Empire have zero candidacy (both require contract completions and infrastructure breadth that bots don't achieve)

## What is being tuned

- **Smuggler ship progression** — smuggler should reach brigantine through luxury margins, currently under-scaling
- **Route diversity** — Mediterranean concentration should be reduced; West African and East Indies routes need to be more attractive to automated players
- **Contract completion rates** — policy bots need to prioritize contract fulfillment; the engine works, the strategy doesn't
- **Insurance adoption** — policy bots need risk evaluation; the system works, the strategic incentive is invisible to bots
- **Victory path thresholds** — Lawful Trade House and Commercial Empire may need threshold adjustments based on achievable play patterns

## What players should expect

- Core gameplay works end-to-end. You can trade, build infrastructure, manage finance, and pursue victory paths.
- Balance is actively being tuned. Some strategies may be significantly stronger than others.
- Saves may break across alpha versions if data formats change.
- The CLI is the intended primary interface. There is no GUI.
- The game is designed for extended play (60-120+ days per run), not quick sessions.

## What is explicitly not being solved yet

- GUI or web interface
- Multiplayer
- Procedural world generation (ports/routes are curated content)
- Sound or visual effects
- Tutorial beyond the welcome screen and docs
- Save migration between versions
```

# Career Paths

Portlight doesn't ask you to pick a career path at the start. It watches what you do and tells you what you built.

## How it works

As you trade, the game tracks your commercial history across seven profile dimensions and four victory paths. Your **career profile** is an interpretation — it reads your trade patterns, infrastructure portfolio, financial discipline, and reputation state to determine what kind of merchant you actually are.

Run `portlight milestones` to see your current profile, milestone progress, and victory path diagnostics.

## The Seven Profile Tags

Your career profile is built from seven scored dimensions. Each is measured from actual game evidence — trades, contracts, infrastructure, finance, reputation:

### Lawful House
You operate within the system. High commercial trust, low customs heat, licenses acquired, contracts completed reliably. The game scores this when you build legitimate access and use it consistently.

**Evidence that builds this tag:** completing contracts, maintaining low heat, acquiring licenses, reaching high trust tiers.

### Shadow Operator
You trade profitably under scrutiny. High customs heat but still solvent, luxury/contraband margins, survival through inspections and seizures. The game scores this when you're profitable despite pressure.

**Evidence that builds this tag:** high heat across regions, profitable trade volume under that heat, surviving seizures, playing as smuggler captain.

### Oceanic Carrier
You reached the distant waters and built a presence there. East Indies standing, long-haul infrastructure, galleon or brigantine operations. The game scores this when you've extended your commercial reach beyond the Mediterranean.

**Evidence that builds this tag:** East Indies regional standing, East Indies broker office, EI access charter, operating a galleon.

### Contract Specialist
You deliver. High contract completion count, early delivery bonuses, reliable fulfillment. The game scores this when contracts are a meaningful part of your income, not just side activity.

**Evidence that builds this tag:** number of completed contracts, early bonus completions.

### Infrastructure Builder
You invested in commercial presence across regions. Warehouses, brokers, licenses across multiple regions. The game scores this when your infrastructure portfolio is broad and active.

**Evidence that builds this tag:** active warehouses, broker offices, licenses, multi-region presence.

### Leveraged Trader
You used credit and managed it well. Borrowed, invested, and repaid without defaulting. The game scores this when credit was a meaningful lever in your operation, not just a mistake.

**Evidence that builds this tag:** total borrowed amount, repayment ratio, zero defaults.

### Risk-Managed Merchant
You insured your operations. Purchased policies, received claim payouts, maintained coverage alongside trust. The game scores this when insurance is an active part of your risk management, not just a purchase.

**Evidence that builds this tag:** policies purchased, claims paid, insurance combined with high trust.

## Profile Confidence

Each tag has a confidence level:

- **Forming** — early signal, too soon to call
- **Moderate** — meaningful evidence, but not your dominant trait
- **Strong** — clear pattern in your trade history
- **Dominant** — this is who you are

Your profile shows a **primary** tag (strongest signal), **secondaries** (meaningful but not dominant), and an **emerging** tag (recent activity that might shift your profile).

## The Four Victory Paths

Victory paths represent complete commercial identities. They're harder to achieve than any single profile tag because they require meeting multiple requirements simultaneously.

### Lawful Trade House
**Identity:** Disciplined legitimacy and premium access.

You built a trade house that the institutions respect. High trust, clean reputation, premium contracts, broad infrastructure. This is the merchant's natural path — but any captain can achieve it by building trust and maintaining low heat.

**What it requires:**
- High commercial trust tier
- Low customs heat
- Completed contracts
- Active licenses
- Infrastructure in multiple regions
- Strong net worth

**Natural fit:** Merchant captain, but achievable by any type through disciplined play.

### Shadow Network
**Identity:** Profitable discreet trade under scrutiny.

You built a profitable operation while the authorities were watching. High heat, luxury margins, survived inspections and seizures, and came out ahead. This isn't about being a criminal — it's about being profitable where the rules make profit harder.

**What it requires:**
- High customs heat (you've attracted attention)
- Strong trade profit despite that heat
- Significant trade volume
- Survival through enforcement actions
- Visits to black market ports

**Natural fit:** Smuggler captain, but merchants who push boundaries can drift here.

### Oceanic Reach
**Identity:** Long-haul commercial power.

You reached the East Indies and built real presence there. Distant infrastructure, premium route mastery, the ship to sustain long voyages. This is about commercial range — trading where others can't or won't.

**What it requires:**
- East Indies regional standing
- East Indies infrastructure (broker, warehouse)
- EI access charter
- Brigantine or galleon operation
- Multi-region trade activity

**Natural fit:** Navigator captain, but any captain who invests in range can pursue it.

### Commercial Empire
**Identity:** Integrated multi-region operation.

You built the whole thing. Infrastructure in every region, diversified revenue, financial leverage, contracts across multiple families. This is the hardest path because it requires breadth, not just depth.

**What it requires:**
- Infrastructure presence in all three regions
- Multiple active licenses
- Credit used and managed well
- Strong net worth
- Diversified trade routes
- Contract completion history

**Natural fit:** No single captain type — this requires sustained investment across every system.

## Victory Diagnostics

`portlight milestones` shows per-path diagnostics:

- **Met** requirements are checked off
- **Missing** requirements show what you still need, with a suggested action
- **Blocked** requirements indicate you've moved in a direction that makes this path harder (e.g., high heat blocks Lawful Trade House)
- **Candidate strength** is a percentage indicating how close you are to qualifying

You can pursue multiple paths simultaneously. The first path you complete is marked as your primary victory. Additional paths can be completed afterward for a broader career legacy.

## Milestones

Milestones are specific achievements the game recognizes along the way. They're grouped into six families:

- **Regional Foothold** — establishing presence in each region
- **Lawful House** — building legitimate commercial standing
- **Shadow Network** — profitable operations under scrutiny
- **Oceanic Reach** — extending commercial range
- **Commercial Finance** — credit, insurance, and leverage milestones
- **Integrated House** — combining multiple systems effectively

Milestones are awarded automatically when the game evaluates your session state. They're never taken away once earned — even if your situation changes afterward.

# Command Reference

All Portlight commands, grouped by purpose. Run `portlight guide` in-game to see this reference in the terminal.

## Trading

### `portlight market`
View prices, stock levels, and affordability at your current port. Shows buy/sell prices, stock, and flood penalty if active.

**When you use it:** Before every trade decision. This is the most-used command in the game.

**Example:** `portlight market`

### `portlight buy <good> <qty>`
Buy goods from the port market into your cargo hold.

**When you use it:** When you've identified something cheap at the current port that sells high elsewhere.

**Example:** `portlight buy grain 15`

### `portlight sell <good> <qty>`
Sell goods from your cargo to the port market. Shifts reputation, may trigger flood penalty.

**When you use it:** At a destination where the good is consumed (low stock, high demand).

**Example:** `portlight sell grain 15`

### `portlight cargo`
View your current cargo hold: goods, quantities, cost basis, provenance.

**When you use it:** To check what you're carrying and where it came from.

**Example:** `portlight cargo`

## Navigation

### `portlight routes`
List available routes from your current port with distance and travel time.

**When you use it:** When deciding where to sail next.

**Example:** `portlight routes`

### `portlight sail <destination>`
Depart for a destination port. Requires provisions and crew.

**When you use it:** When loaded with cargo and ready to travel.

**Example:** `portlight sail al_manar`

### `portlight advance [days]`
Advance time by one or more days. At sea: progresses your voyage. In port: passes time.

**When you use it:** After sailing (to travel) or in port (to wait for market recovery or contract deadlines).

**Example:** `portlight advance` or `portlight advance 5`

### `portlight port`
View information about your current port: features, fees, region.

**When you use it:** When arriving at a new port or checking local services.

**Example:** `portlight port`

### `portlight provision [days]`
Buy provisions (food/water) for the voyage. Default: 10 days.

**When you use it:** Before long voyages. Running out at sea is dangerous.

**Example:** `portlight provision 15`

### `portlight repair [amount]`
Repair hull damage at port. Default: full repair.

**When you use it:** After storms or combat events.

**Example:** `portlight repair`

### `portlight hire [count]`
Hire crew at port. Default: fill to capacity.

**When you use it:** When below optimal crew (slower sailing speed).

**Example:** `portlight hire`

## Contracts

### `portlight contracts`
View the contract board: available offers at your current port.

**When you use it:** When checking what delivery opportunities are available.

**Example:** `portlight contracts`

### `portlight accept <offer_id>`
Accept a contract offer from the board. Creates an obligation with a deadline.

**When you use it:** When a contract aligns with your planned routes.

**Example:** `portlight accept a1b2c3`

### `portlight obligations`
View your active contract obligations: deadlines, progress, sail-time estimates.

**When you use it:** To track what you owe and how much time you have.

**Example:** `portlight obligations`

### `portlight abandon <offer_id>`
Abandon an active contract. Damages trust and standing.

**When you use it:** Only when the cost of completing is clearly worse than the reputation hit.

**Example:** `portlight abandon a1b2c3`

## Infrastructure

### `portlight warehouse [action]`
Manage warehouses. Actions: `lease`, `deposit <good> <qty>`, `withdraw <good> <qty>`, `list`.

**When you use it:** When you want to stage cargo at a port — buy when cheap, store, sell when the market is right.

**Example:**
- `portlight warehouse lease depot` — open a basic warehouse at current port
- `portlight warehouse deposit grain 20` — move grain from cargo to warehouse
- `portlight warehouse withdraw grain 10` — move grain from warehouse to cargo
- `portlight warehouse list` — see inventory at current port

### `portlight office [action]`
Manage broker offices. Actions: `open`, `upgrade`.

**When you use it:** When you want better contract quality in a region. Brokers improve the premium offer weighting on the board.

**Example:** `portlight office open` — open a local broker at your current region

### `portlight license [buy <id>]`
View available licenses or purchase one. Licenses unlock contract families, reduce customs friction, or open premium access.

**When you use it:** When your standing and trust are high enough to qualify and you want to unlock new opportunities.

**Example:**
- `portlight license` — see available licenses
- `portlight license buy med_trade_charter` — purchase a specific license

## Finance

### `portlight insure [buy <id>]`
View insurance options or purchase a policy. Policies cover hull damage, cargo loss, or contract failure.

**When you use it:** When you're carrying valuable cargo on risky routes, or when a contract failure would be devastating.

**Example:**
- `portlight insure` — see available policies
- `portlight insure buy hull_basic` — purchase hull insurance

### `portlight credit [action]`
Manage credit. Actions: `open`, `draw <amount>`, `repay <amount>`, `status`.

**When you use it:** When you need capital faster than your trade income provides. Credit has interest and default risk.

**Example:**
- `portlight credit open` — open a credit line (requires trust/standing)
- `portlight credit draw 200` — borrow 200 silver
- `portlight credit repay 100` — repay 100 silver of outstanding debt

## Career

### `portlight captain`
View your captain identity: type, advantages, pricing modifiers, starting profile.

**When you use it:** To remind yourself of your archetype's strengths and trade-offs.

**Example:** `portlight captain`

### `portlight reputation`
View your full reputation state: regional standing, port standing, customs heat, commercial trust, and recent incidents.

**When you use it:** When deciding whether you qualify for contracts, licenses, or credit. Also useful to track heat pressure.

**Example:** `portlight reputation`

### `portlight milestones`
View career milestones (completed and in progress), victory path diagnostics, and career profile interpretation.

**When you use it:** To see what the game recognizes about your trading career and how close you are to victory paths.

**Example:** `portlight milestones`

### `portlight status`
Overview panel: silver, ship, cargo summary, daily upkeep costs, infrastructure summary.

**When you use it:** Quick snapshot of your overall position.

**Example:** `portlight status`

### `portlight ledger`
View your trade receipt history — every buy and sell with prices, quantities, and provenance.

**When you use it:** To review your trade performance and verify receipt integrity.

**Example:** `portlight ledger`

### `portlight shipyard [buy <ship_id>]`
View available ships or purchase one. Ships differ in cargo capacity, speed, hull strength, crew needs, and storm resistance.

**When you use it:** When you have enough silver for an upgrade and the crew/provisions to sustain a bigger ship.

**Example:**
- `portlight shipyard` — see available ships and prices
- `portlight shipyard buy brigantine` — purchase a brigantine

## System

### `portlight save`
Explicitly save the game. (Auto-save happens after every action.)

**Example:** `portlight save`

### `portlight load`
Load a previously saved game.

**Example:** `portlight load`

### `portlight guide`
Show the in-game grouped command reference.

**Example:** `portlight guide`
```

                                          # Profile: "Lawful House" emerging
```

**Outcome:** Steady silver growth, rising trust, clean reputation. Lawful Trade House candidacy building. Brigantine upgrade around day 20. Career profile shows Lawful House as primary, Contract Specialist as secondary.

---

## Smuggler: Shadow Network

A West African operator trading luxury goods under customs pressure.

**Days 1-10: Luxury margin discovery**
```
portlight new "Kojo" --type smuggler
portlight market                          # Sun Harbor — cotton cheap, silk/spice valuable
portlight buy cotton 10                   # Safe early cargo
portlight sail iron_point                 # Short West African route
portlight advance
portlight sell cotton 10
portlight buy iron 10
portlight sail sun_harbor
portlight advance
portlight sell iron 10                    # Return leg profitable
```

**Days 10-25: Heat management**
```
portlight reputation                      # Heat rising from luxury region trades
portlight market                          # Check for silk/spice availability
portlight buy silk 5                      # Higher margins, but attracts attention
portlight sail palm_cove
portlight advance
portlight advance
portlight sell silk 5                     # Large per-unit margin
portlight status                          # Silver growing fast
                                          # But inspections increasing
```

**Days 25-45: Profitable under pressure**
```
portlight reputation                      # Heat at 15-20 in West Africa
                                          # Inspections happening every few voyages
portlight milestones                      # Shadow Operator tag emerging
                                          # "Profitable under heat" evidence
portlight insure buy hull_basic           # Protect against storm losses
portlight credit open                     # Leverage for bigger cargo runs
portlight credit draw 200
portlight buy silk 8
portlight sail sun_harbor
```

**Outcome:** High margins but constant pressure. Heat management becomes a real skill — knowing when to switch to staples for cooldown, when to push luxury runs. Shadow Network candidacy building. Career profile shows Shadow Operator as primary.

---

## Navigator: Oceanic Reach

A long-haul operator pushing into the East Indies.

**Days 1-15: Mediterranean profit base**
```
portlight new "Yara" --type navigator
portlight market                          # Porto Novo starting port
portlight buy grain 15                    # Build capital with safe trades
portlight sail silva_bay                  # Short Mediterranean route
portlight advance
portlight advance
portlight sell grain 15
portlight buy timber 10                   # Timber from Silva Bay
portlight sail porto_novo
portlight advance
portlight advance
portlight sell timber 10
```

**Days 15-30: Brigantine and range expansion**
```
portlight shipyard buy brigantine         # Speed + cargo upgrade
portlight provision 20                    # Stock up for longer voyages
portlight routes                          # Now longer routes are viable
portlight sail sun_harbor                 # Cross into West Africa
portlight advance
portlight advance
portlight advance
portlight advance
portlight market                          # New region, new opportunities
portlight sell grain 10                   # Mediterranean goods sell well here
portlight buy cotton 15                   # Cotton is cheap in West Africa
```

**Days 30-60: East Indies push**
```
portlight routes                          # East Indies routes visible with brigantine
portlight provision 25                    # Long voyage ahead
portlight sail <east_indies_port>
portlight advance                         # Multi-day voyage
...
portlight market                          # East Indies prices — porcelain cheap
portlight buy porcelain 10
portlight warehouse lease depot           # EI staging warehouse
portlight office open                     # EI broker for premium contracts
portlight milestones                      # Oceanic Carrier tag emerging
```

**Outcome:** Slower start but eventually the most profitable routes. East Indies porcelain and spice back to Mediterranean or West Africa create the highest margins in the game. Oceanic Reach candidacy building. Career profile shows Oceanic Carrier as primary, Infrastructure Builder as secondary.

---

## Reading these examples

These arcs show different strategies, not different difficulty levels. Each captain type has a natural commercial identity, but the game doesn't force you into it. A merchant can push into the East Indies. A smuggler can build legitimate trust. A navigator can work luxury margins.

The career profile and victory paths reflect what you actually did, not what your captain type suggests. That's the design: the game interprets your commercial history, and two runs that end rich in different ways are distinguishable.

### docs/FIRST_VOYAGE.md

# First Voyage

A concrete walkthrough of early-game trading. This covers your first 10-15 days: choosing a captain, understanding the market, making profitable runs, and knowing when each system matters.

## Choose your captain

```bash
portlight new "Your Name" --type merchant
```

Each captain starts in a different position:

- **Merchant** starts in Porto Novo (Mediterranean) with 500 silver. Legitimate operator — best prices, lowest inspection risk. Start here.
- **Smuggler** starts in Sun Harbor (West Africa) with 400 silver. Black market access, luxury margins, but customs are watching.
- **Navigator** starts in Porto Novo with 450 silver. Faster ships and better range, but thinner starting capital.

The welcome screen shows your captain advantages, what's cheap and expensive at your starting port, and concrete first commands.

## Read the market

```bash
portlight market
```

The market table shows every good available at your port:

- **Buy price** — what it costs you to purchase
- **Sell price** — what you'd get selling here (always lower than buy — that's the spread)
- **Stock** — current supply at this port

**Key insight:** Goods with high stock are cheap because the port produces them. Goods with low stock are expensive because the port consumes them. Your profit comes from buying where stock is high and selling where stock is low.

If you see `(flooded: -25%)` next to a sell price, that means you (or the market) have been dumping that good here. The sell price is temporarily depressed. Trade elsewhere or wait for recovery.

## Make your first trade

From Porto Novo, grain is cheap (high stock, high local affinity for production).

```bash
portlight buy grain 10
portlight cargo
```

Check `cargo` to confirm you're loaded. Now find where grain sells well:

```bash
portlight routes
```

Routes show destinations, distance, and estimated travel time. Al-Manar is a Mediterranean port that consumes grain — low stock, low affinity. Good target.

```bash
portlight sail al_manar
```

You're now at sea. Advance day by day:

```bash
portlight advance
```

Each day at sea consumes 1 provision and may trigger events — calm seas, storms, sightings. Your ship's hull, crew, and provisions are real resources. When you arrive:

```bash
portlight sell grain 10
```

Check your profit:

```bash
portlight status
```

## Understand flood penalty

If you sell 20 grain at Al-Manar, then immediately buy more and sell another 20, the second sale earns less. The flood penalty rises when you repeatedly sell the same good at the same port. The market shows the penalty percentage.

**What to do about it:**
- Diversify destinations — sell at different ports
- Diversify goods — don't carry only grain
- Wait — flood penalty decays over time

## When to diversify

After 3-5 profitable grain runs, you'll notice margins thinning. This is normal. The economy is reacting to your trades. Time to explore:

- **Silk and spice** sell for more per unit but are scarcer and riskier (luxury goods attract inspection attention for smugglers)
- **Cotton and iron** offer steady mid-tier margins between West Africa and other regions
- **Timber** from Silva Bay to ports without shipyards

Check markets at every port you visit. The best trades aren't always the obvious ones.

## When to consider contracts

```bash
portlight contracts
```

The contract board shows offers at your current port. Each has:
- A good to deliver
- A destination
- A quantity and deadline
- A reward

Early contracts are simple procurement: deliver X goods to Y port within Z days. The reward is often better than raw trade margin, plus completing contracts builds commercial trust, which unlocks better contracts.

**When to take one:** When you're already planning to trade that route anyway. A contract that aligns with your next 2-3 voyages is free money. A contract that forces you to rush to an unfamiliar port might cost more than it pays.

```bash
portlight accept <offer_id>
portlight obligations
```

The obligations view shows deadline context: how many days left, and estimated sail time to the destination.

## When you're close to a ship upgrade

```bash
portlight shipyard
```

The shipyard shows available ships and their costs. The sloop is your starter — small cargo hold, slow. The brigantine is the first real upgrade: more cargo, faster, better storm resistance.

The in-game hint system will tell you when you're within 200 silver of an upgrade. Don't rush it — an upgrade you can't sustain (provisions for a bigger crew, for example) is worse than a profitable sloop.

## Provisions, hull, and crew

Before every voyage:
- **Check provisions:** `portlight status` shows remaining days. Buy more with `portlight provision 10`.
- **Check hull:** If damaged from storms, repair with `portlight repair`.
- **Check crew:** Full crew means full speed. Hire with `portlight hire`.

Running out of provisions at sea is bad. Running out of hull is worse.

## Next steps

After 10-15 days of profitable trading, you'll have enough silver and understanding to start thinking about:

- **Warehouses** — stage cargo at ports for timing advantage
- **Brokers** — improve contract quality in a region
- **Licenses** — unlock premium contracts and reduce friction

See [COMMANDS.md](COMMANDS.md) for the full command reference and [CAREER_PATHS.md](CAREER_PATHS.md) for what the game is tracking about your commercial identity.

# Known Issues

Active issues identified through the balance harness, stress testing, and manual play. This is not a bug list — these are tuning targets and design limitations acknowledged for the alpha.

## Balance

### Smuggler ship progression
**Severity:** Medium
**Status:** Under investigation

The smuggler captain does not reach brigantine in the current balance simulation (105 runs, mixed_volatility scenario). Merchant reaches it by day 20, navigator by day 11. Smuggler's luxury margins should be sufficient but the automated policy bots don't accumulate silver fast enough for the upgrade.

**Likely cause:** Smuggler's higher inspection rate and seizure risk erodes margins faster than the luxury pricing advantage compensates. The bot strategy also doesn't optimize for the smuggler's specific advantages.

### Mediterranean route concentration
**Severity:** Medium
**Status:** Known, tuning planned

Porto Novo to Silva Bay accounts for 31% of all route traffic in simulated play. This is partly structural (Mediterranean ports have the best early-game margin on staples) and partly because policy bots don't explore West Africa or East Indies aggressively enough.

**Impact:** Feels narrow. Players who discover West African cotton/iron routes and East Indies porcelain will find good margins, but the game doesn't push them there.

### Contract completion rates
**Severity:** Medium
**Status:** Strategy gap, not engine gap

Zero contracts completed across all 105 automated runs. The contract engine works correctly — offers generate, acceptance works, provenance validates, deadlines resolve. The gap is that policy bots don't prioritize carrying the right goods to the right destination within the deadline.

**Impact:** Human players who read the contract board and plan routes accordingly will complete contracts normally. This is a bot strategy limitation, not a game bug.

### Insurance adoption
**Severity:** Low
**Status:** Expected for alpha

Zero insurance purchases across all automated runs. Policies are available and functional. Policy bots don't evaluate risk well enough to decide when insurance is worth the premium.

**Impact:** Human players will discover insurance when they lose valuable cargo to storms or fail a contract. The system works; the incentive clarity could be improved.

## UX

### No save migration
**Severity:** Medium
**Status:** By design for alpha

Save files may break across alpha versions if the data format changes. There is no migration path. Players should expect to start fresh runs when updating.

### Limited error messages for infrastructure
**Severity:** Low
**Status:** Known

Some infrastructure commands (warehouse, office, license, credit) return terse error messages when requirements aren't met. The requirements are documented in the command help, but inline explanations could be clearer.

### No undo
**Severity:** Low
**Status:** By design

There is no undo for trades, contract acceptance, or infrastructure purchases. This is intentional — decisions have consequences. But it means a mistyped command can cost silver or time.

## Performance

### Balance harness speed
**Severity:** Low
**Status:** Acceptable for alpha

Running the full balance harness (105 simulations across 7 scenarios, 3 captains, 5 seeds) takes approximately 20 seconds. Stress test suite (9 scenarios) takes approximately 2 seconds. Both are fast enough for development iteration.

## Feedback

If you're testing Portlight, the most useful feedback is:

- **Route discoveries** — which routes did you find profitable that aren't Porto Novo / Silva Bay?
- **Contract experience** — were contracts worth taking? Were deadlines realistic?
- **Infrastructure timing** — when did you first feel ready for a warehouse or broker?
- **Ship upgrade timing** — did the brigantine feel achievable at a reasonable point?
- **Victory path clarity** — did you understand what the game was recognizing about your career?
- **Balance notes** — did any captain type feel significantly weaker or stronger?

Save files, trade ledger exports, and milestone screenshots are all helpful for tuning.

# Release Notes — Alpha

## What Portlight is

Portlight is a trade-first maritime strategy game played in the terminal. You start as a captain with a small ship and limited silver, and build a merchant career through route arbitrage, contracts, infrastructure investment, financial leverage, and commercial reputation.

The game watches what you build and interprets your career: four victory paths and seven profile tags reflect the kind of trade house you actually created. Two players who both get rich in different ways will see different career profiles.

## What's in this release

### Economy
- 10 ports across 3 regions (Mediterranean, West Africa, East Indies)
- 8 tradeable goods with scarcity-driven pricing
- 17 routes with distance-based travel times
- Flood penalty on repeated sales at the same port

- Provenance tracking on all cargo (port and region of acquisition)

### Voyages
- Multi-day travel with daily event resolution
- Storms, pirate encounters, calm seas, sightings
- Inspections based on customs heat and cargo suspicion
- Provisions, hull, and crew as real resources
- 3 ship classes: sloop, brigantine, galleon

### Captain Identity
- Merchant — legitimate trader, best prices, low inspection risk

- Career profile interpretation: 7 scored tags with confidence levels (forming, moderate, strong, dominant)
- Primary, secondary, and emerging profile tags
- 4 victory paths: Lawful Trade House, Shadow Network, Oceanic Reach, Commercial Empire
- Per-path diagnostics: met, missing, and blocked requirements
- Candidate strength scoring
- First-path-completed flag for career legacy

### Quality

## Known limitations

See [KNOWN_ISSUES.md](KNOWN_ISSUES.md) for specific items. Key notes:

- Balance is actively being tuned — some captain types and strategies are stronger than others
- Saves may break across alpha versions
- CLI is the intended interface; there is no GUI
- Insurance and credit are functional but under-adopted in simulated play
- Contract completion rates in automated testing are lower than expected (strategy gap, not engine gap)
```

### docs/START_HERE.md

```md
# Start Here

This is a 10-minute guide to your first Portlight session. By the end, you'll have made your first profitable trade and understand the basic rhythm of the game.

## Install and start

```bash
pip install -e ".[dev]"
portlight new "Your Name" --type merchant
```

The welcome screen shows your captain identity, the port you're docked at, what's cheap and expensive locally, and suggested first moves.

Three captain types are available:
- `merchant` — best prices, lowest inspection risk, trust grows fast
- `smuggler` — black market access, luxury margins, but higher heat
- `navigator` — faster ships, longer range, early East Indies access

Start with `merchant` for your first run. The other types reward experience.

## Your first trade

```bash
portlight market
```

The market shows every good at your current port: buy price, sell price, stock levels. Look for goods with high stock — they're cheap here because the port produces them.

```bash
portlight buy grain 10
```

Buy something cheap. Grain at a Mediterranean port is usually a safe bet.

```bash
portlight routes
```

This shows where you can sail from here, with distance and travel time. Look for a destination where your cargo is consumed (low stock, high demand).

```bash
portlight sail al_manar
portlight advance
```

Sail and advance through the voyage. Events may happen — storms, sightings, inspections. `advance` moves time forward one day at a time.

```bash
portlight sell grain 10
```

Sell at the destination. The margin between your buy price and sell price is your profit.

```bash
portlight ledger
```

The ledger shows your trade receipt history with verifiable entries.

## What to focus on early

**Profit per voyage.** Your goal in the first 10-20 days is to learn which routes are profitable. Buy where stock is high, sell where it's consumed. The price difference minus port fees and travel costs is your real margin.

**Provisions.** You consume provisions every day at sea. If you run out, your crew suffers. Buy provisions before long voyages: `portlight provision 15`.

**Ship condition.** Storms and events damage your hull. Repair at port: `portlight repair`.

## What to ignore at first

**Contracts.** Available early, but don't stress about them until you understand route profitability. Check them with `portlight contracts` when you're ready.

**Infrastructure.** Warehouses, brokers, and licenses cost silver and have daily upkeep. Wait until you have a steady income loop before investing. You'll know it's time when you have 500+ silver and a predictable route.

**Insurance and credit.** These are mid-game tools. Insurance protects against losses you can't absorb. Credit accelerates moves you can't afford yet. Both have costs and risks. Ignore them until you understand the upkeep economy.

**Victory paths.** The game tracks your career milestones automatically. You don't need to optimize for them early. Just trade well and check `portlight milestones` occasionally to see what the game recognizes.

## When to care about each system

| Silver range | Day range | What opens up |
|-------------|-----------|---------------|
| 0-500 | Days 1-10 | Basic trading, route discovery, provisioning |
| 500-2000 | Days 10-25 | Ship upgrades, first warehouse, first broker, simple contracts |
| 2000-5000 | Days 25-50 | Licenses, insurance, credit, multi-region trading |
| 5000+ | Days 50+ | Victory path pursuit, full infrastructure portfolio |

These are rough guides, not hard gates. Play at your own pace.

## Reading the career ledger

```bash
portlight milestones
```

This shows:
- **Completed milestones** — specific achievements the game has recognized from your trade history
- **Victory path progress** — how close you are to each of the four commercial destinies
- **Career profile** — what kind of trader the game thinks you are, based on evidence

The career profile isn't a choice you make. It's an interpretation of what you've actually done. Two players with different strategies will see different profiles.

## Key commands

| What you want to do | Command |
|---------------------|---------|
| See everything at once | `portlight status` |
| Find profitable goods | `portlight market` |
| Check your cargo | `portlight cargo` |
| See where you can go | `portlight routes` |
| Travel somewhere | `portlight sail <destination>` |
| Pass time | `portlight advance` |
| See all commands | `portlight guide` |

## Next steps

Once you're comfortable with basic trading, read [FIRST_VOYAGE.md](FIRST_VOYAGE.md) for a detailed walkthrough of early-game strategy, or jump to [COMMANDS.md](COMMANDS.md) for the full command reference.

# Why Portlight

## Trade-first, not survival-first

Most maritime games lead with danger: storms sink your ship, pirates steal your cargo, starvation ends your run. Portlight has all of those — but they're not the point.

The point is trade. Finding margin. Timing cargo. Building the infrastructure that turns a profitable route into a commercial operation. The storms matter because they threaten your cargo timing, not because the game wants to kill you.

## Prices are alive

Portlight's economy is scarcity-driven. Every port has goods it produces cheaply (high stock, low local affinity for consumption) and goods it consumes hungrily (low stock, high demand). When you sell grain at a port that already has plenty, the price drops — and keeps dropping if you dump repeatedly (flood penalty). When you buy silk at a port where it's scarce, the price climbs.

This means profitable routes exist because of structural economic differences between ports, not because someone hardcoded "sell silk here for 2x." And those routes degrade if you or the market over-exploit them.

## Contracts and provenance

Contracts don't just say "deliver 20 grain." They require provenance — the grain must be tracked from purchase to delivery. You can't fake completion by buying at the destination port. This makes warehousing strategic: staged cargo at the right port means faster contract completion.

Contract families gate behind trust and standing. You earn access to better contracts by being commercially reliable, not by grinding a single number.

## Infrastructure as commercial advantage

Warehouses, broker offices, and licenses aren't upgrades that buff your stats. They change how you trade:

- **Warehouses** let you decouple buying from selling. Buy when cheap, store, sell when the market is right. Timing play.
- **Brokers** improve the quality of contract offers in a region. Information advantage.
- **Licenses** unlock contract families and reduce friction. Access advantage.

Each has real upkeep. Leasing infrastructure you can't sustain is worse than not having it.

## Finance has teeth

Credit lets you move faster — draw silver to fund a bigger cargo run or lease infrastructure before you can afford it outright. But interest accrues, payment deadlines are real, and three defaults freeze your credit line and damage your commercial trust.

Insurance covers real losses — storm damage, cargo loss, contract failure. But policies have coverage caps, exclusion conditions, and heat surcharges. High-heat smugglers pay more for coverage and face denial conditions.

## The career is interpreted, not chosen

You don't pick a victory path at the start. You trade, and the game reads what you built. Your career profile emerges from evidence: trade patterns, contract history, infrastructure portfolio, route diversity, financial discipline.

The four victory paths — Lawful Trade House, Shadow Network, Oceanic Reach, Commercial Empire — represent distinct commercial identities. Two players who both get rich but in different ways will see different career profiles and qualify for different paths.

## The CLI is the product

Portlight is a terminal game, not a terminal game waiting to become a GUI game. The CLI is designed for the rhythm of trade decisions: inspect, decide, execute, read the result. Rich terminal rendering makes the information dense and legible.

The `guide` command shows all commands grouped by purpose. The welcome screen after `portlight new` gives you concrete first moves. Flood penalties are explained inline. Contract deadlines show sail-time context. The interface teaches you the game as you play.

## What Portlight is not

- It's not a roguelike. Runs are long, building over dozens of days.
- It's not a tycoon game. You're one captain, not a corporation.
- It's not a narrative game. There's no plot — your commercial history is the story.
- It's not finished. This is an alpha with active balance tuning. But the systems are real, the truth model is tested, and the career arc works end to end.

Una estrategia marítima centrada en el comercio, donde construyes una carrera como comerciante a través de la optimización de rutas, contratos, infraestructura, finanzas y reputación comercial en una economía regional dinámica.

## ¿Por qué Portlight?

La mayoría de los juegos de comercio simplifican el comercio a un número que simplemente aumenta. Portlight trata el comercio como una disciplina comercial:

- **Los precios reaccionan a tus transacciones.** Si vendes grandes cantidades de grano en un puerto, el precio se desploma. Cada venta altera el mercado local.
- **Los puertos tienen identidades económicas reales.** Porto Novo produce grano a bajo costo. Al-Manar consume seda con avidez. Estas características no son aleatorias, sino estructurales.
- **Los viajes implican riesgos.** Tormentas, piratas, inspecciones. Tus provisiones, el casco y la tripulación son importantes.
- **Los contratos requieren pruebas.** Debes entregar los productos correctos en el puerto correcto, con un registro de procedencia verificable. No se permiten falsificaciones.
- **La infraestructura cambia la forma en que operas.** Los almacenes te permiten almacenar mercancías. Los intermediarios mejoran la calidad de los contratos. Las licencias desbloquean acceso premium.
- **El crédito es una herramienta poderosa, pero con riesgos.** El crédito te permite actuar más rápido. Si incumples, perderás acceso a él.
- **El juego evalúa lo que has construido.** Tu historial comercial, infraestructura, reputación y rutas forman un perfil de carrera. El juego te indica qué tipo de empresa comercial eres realmente.

## El Ciclo Principal

1. Analiza el mercado: encuentra qué productos son baratos aquí y caros en otro lugar.
2. Compra mercancías: carga tu bodega.
3. Navega: atraviesa rutas bajo la presión del clima, la tripulación y las provisiones.
4. Vende: obtén ganancias, altera el mercado local.
5. Reinvierta: mejora tu barco, alquila un almacén, abre una oficina de intermediarios.
6. Construye acceso: gana confianza, reduce la atención negativa, desbloquea contratos y licencias.
7. Persigue un destino comercial: cuatro caminos distintos hacia la victoria, basados en lo que realmente has construido.

## Guía de inicio rápido

```bash
# Install
pip install -e ".[dev]"

# Start a new game
portlight new "Captain Hawk" --type merchant

# Look at what's for sale
portlight market

# Buy cheap goods
portlight buy grain 10

# Check available routes
portlight routes

# Sail to where grain sells high
portlight sail al_manar

# Advance through the voyage
portlight advance

# Sell at destination
portlight sell grain 10

# See your trade history
portlight ledger

# Check your career progress
portlight milestones
```

Consulta [docs/START_HERE.md](docs/START_HERE.md) para una primera sesión guiada y [docs/FIRST_VOYAGE.md](docs/FIRST_VOYAGE.md) para una descripción detallada de las primeras etapas del juego.

## Tipos de Capitanes

| Capitán | Identidad | Ventaja | Compromiso |
|---------|----------|------|-----------|
| **Merchant** | Comerciante con licencia, base en el Mediterráneo | Mejores precios, tasas de inspección más bajas, la confianza crece más rápido. | Sin acceso al mercado negro. |
| **Smuggler** | Operador discreto, base en África Occidental. | Acceso al mercado negro, márgenes de lujo, comercio de contrabando. | Mayor atención negativa, más inspecciones. |
| **Navigator** | Explorador de aguas profundas, base en el Mediterráneo. | Barcos más rápidos, mayor alcance, acceso temprano a las Indias Orientales. | Posición comercial inicial más débil. |

## Sistemas

**Economía:** Precios determinados por la escasez en 10 puertos, 8 productos, 17 rutas. Las penalizaciones por sobreproducción castigan la venta masiva. Los shocks del mercado crean oportunidades regionales.

**Viajes:** Viajes de varios días con eventos climáticos, encuentros con piratas e inspecciones. Las provisiones, el casco y la tripulación son recursos reales.

**Capitanes:** Tres arquetipos distintos con diferencias de precios del 8 al 20%, posiciones de inicio únicas y diferentes perfiles de acceso.

**Contratos:** Seis familias de contratos bloqueadas por la confianza y la reputación. Entrega con validación de procedencia. Plazos reales con consecuencias reales.

**Reputación:** Posición regional, reputación específica de cada puerto, atención de las aduanas y confianza comercial. Un modelo de acceso de múltiples ejes que abre y cierra puertas.

**Infraestructura:** Almacenes (3 niveles), oficinas de intermediarios (2 niveles en 3 regiones) y 5 licencias comprables. Cada una cambia el tiempo, la escala o el acceso al comercio.

**Seguro:** Pólizas de seguro de casco, carga y garantía de contrato. Cargos por atención negativa. Resolución de reclamaciones con condiciones de denegación.

**Crédito:** Tres niveles de crédito con acumulación de intereses, plazos de pago y consecuencias por incumplimiento. Una herramienta poderosa con riesgos reales.

**Carrera** — 27 hitos en 6 categorías. Interpretación del perfil de carrera (etiquetas primarias/secundarias/emergentes). Cuatro caminos hacia la victoria: Casa Comercial Legítima, Red de la Sombra, Alcance Oceánico e Imperio Comercial.

## Caminos hacia la Victoria

- **Casa Comercial Legítima** — Legitimidad disciplinada. Alta confianza, contratos premium, reputación intachable, amplia infraestructura.
- **Red de la Sombra** — Comercio discreto y rentable. Márgenes de lujo bajo escrutinio, gestión de riesgos, operaciones resilientes.
- **Alcance Oceánico** — Poder comercial de largo alcance. Acceso a las Indias Orientales, infraestructura distante, dominio de rutas premium.
- **Imperio Comercial** — Operación integrada en múltiples regiones. Infraestructura en cada región, diversificación de ingresos, apalancamiento financiero.

Consulte [docs/CAREER_PATHS.md](docs/CAREER_PATHS.md) para obtener descripciones detalladas dirigidas al jugador.

## Estado Alpha

Portlight está en estado alpha. Los sistemas principales están completos y han sido sometidos a pruebas de estrés, pero el equilibrio se está ajustando activamente.

**Lo que está funcionando correctamente:**
- Todos los sistemas son funcionales de extremo a extremo.
- 609 pruebas en 24 archivos.
- 14 invariantes entre sistemas aplicadas bajo 9 escenarios de estrés compuestos.
- Sistema de equilibrio con 7 bots de política en 7 paquetes de escenarios.

**Lo que se está ajustando:**
- Escalado de contrabandistas (actualmente con un rendimiento inferior en la progresión de la nave).
- Concentración de rutas en el Mediterráneo (Porto Novo / Silva Bay dominan el tráfico).
- Tasas de finalización de contratos (fallas en la lógica de entrega en ejecuciones automatizadas).
- Adopción de seguros (actualmente cercana a cero en pruebas simuladas).

Une stratégie maritime axée sur le commerce, où vous construisez une carrière de commerçant grâce à l'arbitrage des routes, aux contrats, aux infrastructures, à la finance et à la réputation commerciale, le tout au sein d'une économie régionale dynamique.

## Pourquoi Portlight ?

La plupart des jeux de commerce réduisent le commerce à un simple chiffre qui augmente. Portlight considère le commerce comme une discipline commerciale :

- **Les prix réagissent à vos transactions.** Décharger une cargaison de céréales dans un port fait chuter le prix. Chaque vente modifie le marché local.
- **Les ports ont une identité économique réelle.** Porto Novo produit des céréales à bas prix. Al-Manar consomme avidement de la soie. Ce n'est pas aléatoire, c'est structurel.
- **Les voyages comportent des risques.** Tempêtes, pirates, inspections. Vos provisions, la coque de votre navire et votre équipage sont importants.
- **Les contrats exigent des preuves.** Livrez les bons produits au bon port avec une traçabilité vérifiée. Pas de fausses déclarations.
- **Les infrastructures modifient votre façon de commercer.** Les entrepôts vous permettent de stocker des marchandises. Les courtiers améliorent la qualité des contrats. Les licences débloquent un accès privilégié.
- **La finance est un levier puissant.** Le crédit vous permet d'agir plus rapidement. En cas de défaut de paiement, les portes se referment.
- **Le jeu analyse ce que vous avez construit.** Votre historique commercial, vos infrastructures, votre réputation et vos itinéraires forment un profil de carrière. Le jeu vous indique le type de société commerciale que vous êtes réellement.

## Le cycle principal

1. Analysez le marché : trouvez ce qui est bon marché ici et cher ailleurs.
2. Achetez des marchandises : chargez votre cale.
3. Naviguez : traversez des routes sous la pression des conditions météorologiques, de l'équipage et des provisions.
4. Vendez : réalisez des bénéfices, modifiez le marché local.
5. Réinvestissez : améliorez votre navire, louez un entrepôt, ouvrez un bureau de courtage.
6. Développez votre accès : gagnez la confiance, réduisez les risques, débloquez des contrats et des licences.
7. Suivez un destin commercial : quatre voies de victoire distinctes basées sur ce que vous avez réellement construit.

## Types de capitaines

| Capitaine | Identité | Avantage | Compromis |
|---------|----------|------|-----------|
| **Merchant** | Commerçant agréé, base en Méditerranée | Meilleurs prix, taux d'inspection plus faibles, la confiance grandit plus rapidement. | Pas d'accès au marché noir. |
| **Smuggler** | Opérateur discret, base en Afrique de l'Ouest. | Accès au marché noir, marges sur les produits de luxe, commerce de contrebande. | Risque accru, plus d'inspections. |
| **Navigator** | Explorateur des mers, base en Méditerranée. | Navires plus rapides, plus grande portée, accès anticipé aux Indes orientales. | Position commerciale initiale plus faible. |

## Systèmes

**Économie** : Tarification basée sur la rareté dans 10 ports, avec 8 produits et 17 itinéraires. Les pénalités de surproduction punissent le déversement. Les chocs du marché créent des opportunités régionales.

**Voyages** : Trajets de plusieurs jours avec des événements météorologiques, des rencontres avec des pirates et des inspections. Les provisions, la coque et l'équipage sont des ressources réelles.

**Capitaines** : Trois archétypes distincts avec des écarts de prix de 8 à 20 %, des positions de départ uniques et des profils d'accès différents.

**Contrats** : Six familles de contrats verrouillées par la confiance et la réputation. Livraison validée par la traçabilité. Délais réels avec de réelles conséquences.

**Réputation** : Réputation régionale, réputation spécifique à chaque port, niveau de contrôle douanier et confiance commerciale. Un modèle d'accès multi-axes qui ouvre et ferme les portes.

**Infrastructures** : Entrepôts (3 niveaux), bureaux de courtage (2 niveaux dans 3 régions) et 5 licences à acheter. Chacun modifie le calendrier, l'échelle ou l'accès au commerce.

**Assurance** : Polices d'assurance pour la coque, les marchandises et la garantie des contrats. Surcharges liées au risque. Règlement des sinistres avec conditions de refus.

**Crédit** : Trois niveaux de crédit avec intérêts, échéances de paiement et conséquences en cas de défaut. Un levier avec un risque réel.

**Carrière** — 27 étapes clés réparties en 6 catégories. Interprétation du profil de carrière (tags principaux/secondaires/émergents). Quatre voies vers la victoire : Maison Commerciale Légitime, Réseau Clandestin, Influence Maritime, et Empire Commercial.

## Voies vers la victoire

- **Maison Commerciale Légitime** — Légitimité disciplinée. Forte confiance, contrats premium, réputation irréprochable, vaste infrastructure.
- **Réseau Clandestin** — Commerce discret et rentable. Marges de luxe sous surveillance, gestion des risques, opérations résilientes.
- **Influence Maritime** — Puissance commerciale à longue distance. Accès aux Indes, infrastructure distante, maîtrise des routes premium.
- **Empire Commercial** — Opération intégrée multi-régionale. Infrastructure dans chaque région, diversification des revenus, levier financier.

एक ऐसा समुद्री रणनीति गेम जहाँ आप व्यापार के माध्यम से अपना करियर बनाते हैं, जिसमें रूट आर्बिट्रेज, अनुबंध, बुनियादी ढांचा, वित्त और एक जीवंत क्षेत्रीय अर्थव्यवस्था में व्यावसायिक प्रतिष्ठा शामिल है।

## पोर्टलाइट क्यों?

ज्यादातर व्यापारिक गेम व्यापार को एक ऐसी संख्या में बदलते हैं जो बढ़ती है। पोर्टलाइट व्यापार को एक व्यावसायिक अनुशासन के रूप में देखता है:

- **कीमतें आपके व्यापार पर प्रतिक्रिया करती हैं।** यदि आप किसी बंदरगाह पर अनाज बेचते हैं, तो कीमत गिर जाती है। हर बिक्री स्थानीय बाजार को बदल देती है।
- **बंदरगाहों की वास्तविक आर्थिक पहचान होती है।** पोर्टो नोवो सस्ते में अनाज का उत्पादन करता है। अल-मानार बड़ी मात्रा में रेशम की खपत करता है। ये यादृच्छिक नहीं हैं - ये संरचनात्मक हैं।
- **यात्राओं में जोखिम होता है।** तूफान, समुद्री डाकू, निरीक्षण। आपके प्रावधान, जहाज और चालक दल महत्वपूर्ण हैं।
- **अनुबंधों के लिए प्रमाण की आवश्यकता होती है।** सही माल को सही बंदरगाह पर ट्रैक किए गए स्रोत के साथ पहुंचाएं। इसमें कोई धोखाधड़ी नहीं है।
- **बुनियादी ढांचा आपके व्यापार के तरीके को बदलता है।** गोदाम आपको माल तैयार करने की अनुमति देते हैं। ब्रोकर अनुबंध की गुणवत्ता में सुधार करते हैं। लाइसेंस प्रीमियम पहुंच को अनलॉक करते हैं।
- **वित्त एक शक्तिशाली उपकरण है।** क्रेडिट आपको तेजी से आगे बढ़ने की अनुमति देता है। यदि आप चूक जाते हैं, तो रास्ते बंद हो जाते हैं।
- **गेम आपके द्वारा बनाए गए चीज़ों को समझता है।** आपका व्यापार इतिहास, बुनियादी ढांचा, प्रतिष्ठा और मार्ग एक करियर प्रोफाइल बनाते हैं। गेम आपको बताता है कि आप वास्तव में किस प्रकार का व्यापारिक घर हैं।

## मुख्य प्रक्रिया

1. बाजार का निरीक्षण करें - पता करें कि यहाँ क्या सस्ता है और कहीं और क्या महंगा है।
2. माल खरीदें - अपने जहाज का कार्गो डिब्बा भरें।
3. यात्रा करें - मौसम, चालक दल और प्रावधानों के दबाव में मार्गों को पार करें।
4. बेचें - लाभ कमाएं, स्थानीय बाजार को बदलें।
5. पुनर्निवेश करें - अपने जहाज को अपग्रेड करें, एक गोदाम किराए पर लें, एक ब्रोकर कार्यालय खोलें।
6. पहुंच प्राप्त करें - विश्वास अर्जित करें, जोखिम कम करें, अनुबंध और लाइसेंस अनलॉक करें।
7. एक व्यावसायिक भाग्य का पीछा करें - आपके द्वारा वास्तव में बनाए गए चार अलग-अलग जीत के रास्ते।

## कप्तान के प्रकार

| कप्तान | पहचान | विशेषता | ट्रेड-ऑफ |
|---------|----------|------|-----------|
| **Merchant** | लाइसेंस प्राप्त व्यापारी, भूमध्यसागरीय क्षेत्र में | बेहतर कीमतें, कम निरीक्षण दर, विश्वास तेजी से बढ़ता है | ब्लैक मार्केट तक पहुंच नहीं |
| **Smuggler** | गुप्त संचालक, पश्चिम अफ्रीका में | ब्लैक मार्केट तक पहुंच, लग्जरी मार्जिन, अवैध व्यापार | अधिक जोखिम, अधिक निरीक्षण |
| **Navigator** | गहरे पानी का अन्वेषक, भूमध्यसागरीय क्षेत्र में | तेज़ जहाज, लंबी दूरी, पूर्वी द्वीपों तक जल्दी पहुंच | शुरुआत में कमजोर व्यावसायिक स्थिति |

## सिस्टम

**अर्थव्यवस्था** - 10 बंदरगाहों, 8 वस्तुओं और 17 मार्गों में कमी से प्रेरित मूल्य निर्धारण। डंपिंग के लिए दंड। बाजार में झटके क्षेत्रीय अवसर पैदा करते हैं।

**यात्राएं** - बहु-दिवसीय यात्राएं जिसमें मौसम की घटनाएं, समुद्री डाकू मुठभेड़ और निरीक्षण शामिल हैं। प्रावधान, जहाज और चालक दल वास्तविक संसाधन हैं।

**कप्तान** - तीन अलग-अलग प्रकार के कप्तान, जिनमें 8-20% मूल्य अंतर, अद्वितीय शुरुआती स्थितियां और अलग-अलग पहुंच प्रोफाइल हैं।

**अनुबंध** - छह अनुबंध परिवार जो विश्वास और प्रतिष्ठा से बंधे हैं। स्रोत-सत्यापित डिलीवरी। वास्तविक समय सीमा और वास्तविक परिणाम।

**प्रतिष्ठा** - क्षेत्रीय स्थिति, बंदरगाह-विशिष्ट प्रतिष्ठा, सीमा शुल्क जोखिम और व्यावसायिक विश्वास। एक बहु-अक्षीय पहुंच मॉडल जो दरवाजे खोलता और बंद करता है।

**बुनियादी ढांचा** - गोदाम (3 स्तर), ब्रोकर कार्यालय (3 क्षेत्रों में 2 स्तर) और 5 खरीद योग्य लाइसेंस। प्रत्येक व्यापार के समय, पैमाने या पहुंच को बदलता है।

**बीमा** - जहाज, माल और अनुबंध गारंटी नीतियां। जोखिम शुल्क। दावा समाधान जिसमें अस्वीकृति की शर्तें हैं।

**क्रेडिट** - ब्याज, भुगतान की समय सीमा और चूक के परिणामों के साथ क्रेडिट के तीन स्तर। वास्तविक जोखिम के साथ एक शक्तिशाली उपकरण।

**करियर** — 6 श्रेणियों में 27 महत्वपूर्ण पड़ाव। करियर प्रोफाइल का विश्लेषण (प्राथमिक/माध्यमिक/उभरते हुए पहलू)। चार सफलता के मार्ग: "कानूनी व्यापारिक घर", "छाया नेटवर्क", "समुद्री विस्तार", और "वाणिज्यिक साम्राज्य"।

## सफलता के मार्ग

- **कानूनी व्यापारिक घर** — अनुशासित और वैध। उच्च विश्वसनीयता, प्रीमियम अनुबंध, स्वच्छ प्रतिष्ठा, व्यापक बुनियादी ढांचा।
- **छाया नेटवर्क** — लाभदायक और गुप्त व्यापार। जांच के दायरे में आने वाले उच्च लाभ, जोखिम प्रबंधन, लचीला संचालन।
- **समुद्री विस्तार** — लंबी दूरी का वाणिज्यिक प्रभुत्व। पूर्व इंडीज तक पहुंच, दूरस्थ बुनियादी ढांचा, प्रीमियम मार्गों पर महारत।
- **वाणिज्यिक साम्राज्य** — एकीकृत, बहु-क्षेत्रीय संचालन। प्रत्येक क्षेत्र में बुनियादी ढांचा, विविध राजस्व, वित्तीय लाभ।

Un gioco di strategia marittima incentrato sul commercio, in cui si costruisce una carriera commerciale attraverso l'arbitraggio di prezzi, i contratti, le infrastrutture, la finanza e la reputazione commerciale in un'economia regionale dinamica.

## Perché Portlight

La maggior parte dei giochi di commercio semplifica il commercio in un numero che aumenta. Portlight considera il commercio come una disciplina commerciale:

- **I prezzi reagiscono alle vostre transazioni.** Se vendete grandi quantità di grano in un porto, il prezzo crolla. Ogni vendita modifica il mercato locale.
- **I porti hanno vere identità economiche.** Porto Novo produce grano a basso costo. Al-Manar consuma avidamente seta. Queste caratteristiche non sono casuali, ma strutturali.
- **I viaggi comportano dei rischi.** Tempeste, pirati, ispezioni. Le vostre provviste, lo scafo e l'equipaggio sono importanti.
- **I contratti richiedono prove.** Consegnate le merci giuste al porto giusto, con una tracciabilità verificabile. Non si può barare.
- **Le infrastrutture cambiano il modo in cui commerciate.** I magazzini vi permettono di accumulare merci. Gli agenti migliorano la qualità dei contratti. Le licenze sbloccano l'accesso a servizi premium.
- **La finanza è una leva potente.** Il credito vi permette di agire più rapidamente. Se non riuscite a pagare, le opportunità si chiudono.
- **Il gioco valuta ciò che avete costruito.** La vostra storia commerciale, le infrastrutture, la reputazione e le rotte formano un profilo professionale. Il gioco vi dice che tipo di azienda commerciale siete realmente.

## Il Ciclo Principale

1. Analizzate il mercato: trovate ciò che è economico qui e costoso altrove.
2. Acquistate merci: caricate il vostro carico.
3. Navigate: percorrete le rotte, tenendo conto delle condizioni meteorologiche, dell'equipaggio e delle provviste.
4. Vendete: guadagnate un margine di profitto e influenzate il mercato locale.
5. Reinvestite: migliorate la vostra nave, affittate un magazzino, aprite una filiale di un'agenzia.
6. Aumentate l'accesso: guadagnate fiducia, riducete l'attenzione indesiderata, sbloccate contratti e licenze.
7. Perseguite un destino commerciale: quattro percorsi di vittoria distinti, basati su ciò che avete effettivamente costruito.

## Tipi di Capitano

| Capitano | Identità | Vantaggio | Compromesso |
|---------|----------|------|-----------|
| **Merchant** | Commerciante con licenza, base nel Mediterraneo | Prezzi migliori, tassi di ispezione più bassi, la fiducia cresce più rapidamente | Nessun accesso al mercato nero |
| **Smuggler** | Operatore discreto, base in Africa occidentale | Accesso al mercato nero, margini elevati per i beni di lusso, commercio di contrabbando | Maggiore attenzione, più ispezioni |
| **Navigator** | Esploratore delle acque profonde, base nel Mediterraneo | Navi più veloci, maggiore autonomia, accesso anticipato alle Indie Orientali | Posizione commerciale iniziale più debole |

## Sistemi

**Economia** — Prezzi determinati dalla scarsità in 10 porti, con 8 merci e 17 rotte. Le penalità per l'eccessiva offerta puniscono la vendita a prezzi troppo bassi. Gli shock del mercato creano opportunità regionali.

**Viaggi** — Viaggi di più giorni con eventi meteorologici, incontri con pirati e ispezioni. Provviste, scafo e equipaggio sono risorse reali.

**Capi** — Tre archetipi distinti con differenze di prezzo dell'8-20%, posizioni di partenza uniche e profili di accesso diversi.

**Contratti** — Sei famiglie di contratti accessibili in base alla fiducia e alla reputazione. Consegne con tracciabilità verificata. Scadenze reali con conseguenze reali.

**Reputazione** — Posizione regionale, reputazione specifica per ogni porto, attenzione delle autorità doganali e fiducia commerciale. Un modello di accesso multi-dimensionale che apre e chiude opportunità.

**Infrastrutture** — Magazzini (3 livelli), uffici di agenzia (2 livelli in 3 regioni) e 5 licenze acquistabili. Ognuna modifica i tempi, la scala o l'accesso al commercio.

**Assicurazione** — Polizze di assicurazione per lo scafo, le merci e la garanzia dei contratti. Sovraccarichi dovuti all'attenzione indesiderata. Risoluzione dei sinistri con condizioni di diniego.

**Credito** — Tre livelli di credito con interessi, scadenze di pagamento e conseguenze in caso di mancato pagamento. Una leva finanziaria con rischi reali.

**Carriera** — 27 tappe fondamentali suddivise in 6 aree. Interpretazione del profilo di carriera (etichette primarie/secondarie/emergenti). Quattro percorsi per la vittoria: Casa Commerciale Legale, Rete Ombra, Portata Oceanica e Impero Commerciale.

## Percorsi per la vittoria

- **Casa Commerciale Legale** — Legittimità disciplinata. Elevata fiducia, contratti premium, reputazione impeccabile, vasta infrastruttura.
- **Rete Ombra** — Commercio discreto e redditizio. Margini di lusso sotto controllo, gestione del rischio, operazioni resilienti.
- **Portata Oceanica** — Potenza commerciale a lungo raggio. Accesso alle Indie Orientali, infrastrutture distanti, padronanza delle rotte premium.
- **Impero Commerciale** — Operazione integrata in più regioni. Infrastrutture in ogni regione, diversificazione delle entrate, leva finanziaria.

Consultare [docs/CAREER_PATHS.md](docs/CAREER_PATHS.md) per descrizioni dettagliate rivolte ai giocatori.

## Riferimento dei comandi

Eseguire `portlight guide` all'interno del gioco per una guida raggruppata dei comandi, oppure consultare [docs/COMMANDS.md](docs/COMMANDS.md).

| Gruppo | Comandi |
|-------|----------|
| Commercio | `market`, `buy`, `sell`, `cargo` |
| Navigazione | `routes`, `sail`, `advance`, `port`, `provision`, `repair`, `hire` |
| Contratti | `contracts`, `accept`, `obligations`, `abandon` |

| Finanza | `insure`, `credit` |
| Carriera | `captain`, `reputation`, `milestones`, `status`, `ledger`, `shipyard` |
| Sistema | `save`, `load`, `guide` |

## Stato Alpha

Portlight è in fase alpha. I sistemi principali sono completi e sottoposti a test di stress, ma la bilanciamento è in fase di ottimizzazione.

**Cosa è solido:**
- Tutti i sistemi funzionanti end-to-end
- 609 test su 24 file
- 14 invarianti inter-sistema applicati in 9 scenari di stress complessi
- Sistema di bilanciamento con 7 bot di policy su 7 pacchetti di scenari

**Cosa è in fase di ottimizzazione:**
- Scalabilità dei contrabbandieri (attualmente sottoperformante nella progressione della nave)
- Concentrazione delle rotte nel Mediterraneo (Porto Novo / Silva Bay dominano il traffico)
- Tassi di completamento dei contratti (lacune nella logica di consegna nelle esecuzioni automatizzate)
- Adozione dell'assicurazione (attualmente prossima allo zero nelle simulazioni)

Consultare [docs/ALPHA_STATUS.md](docs/ALPHA_STATUS.md) per i dettagli e [docs/KNOWN_ISSUES.md](docs/KNOWN_ISSUES.md) per problemi specifici.

## Sicurezza e dati

Portlight è un gioco **CLI esclusivamente locale**. Non stabilisce connessioni di rete durante il gioco. Dati utilizzati: file di salvataggio locali (`saves/`) e file di report (`artifacts/`), tutti in formato JSON sul file system locale. Nessuna informazione sensibile, credenziali, telemetria o servizi remoti. Non sono richieste autorizzazioni elevate. Consultare [SECURITY.md](SECURITY.md) per la politica completa.

このゲームでは、ルートの価格差、契約、インフラ、金融、そして地域経済全体に影響を与える商業的評判を通じて、交易業者としてのキャリアを築き上げていきます。

## Portlightを選ぶ理由

多くの交易ゲームでは、交易は単に数値が上昇するだけのものとして扱われます。Portlightでは、交易を商業的な活動として捉えています。

- **価格はあなたの取引によって変動します。** ある港に穀物を大量に供給すると、価格が暴落します。すべての販売が地域の市場に影響を与えます。
- **各港には独自の経済的な特徴があります。** ポルトノボは安価な穀物を生産し、アル・マナールは絹を渇望しています。これらはランダムなものではなく、構造的なものです。
- **航海にはリスクが伴います。** 嵐、海賊、検査などがあります。積載量、船体、そして乗組員が重要になります。
- **契約には証拠が必要です。** 正しい商品を、追跡可能な供給元とともに、正しい港に配達する必要があります。不正は許されません。
- **インフラは交易方法を変えます。** 倉庫は貨物を一時的に保管できます。仲介業者は契約の質を向上させます。ライセンスは特別なアクセス権を付与します。
- **金融は強力なツールです。** 信用は取引を加速させますが、デフォルトすると、取引の機会が失われます。
- **ゲームはあなたが築き上げたものを評価します。** あなたの取引履歴、インフラ、評判、そして航路は、あなたのキャリアを形成します。ゲームは、あなたがどのような交易会社なのかを教えてくれます。

## ゲームの流れ

1. 市場を調査する：どこで安く、どこで高く売れるかを見つける。
2. 貨物を購入する：船倉に積み込む。
3. 航海する：天候、乗組員、そして食料の状況を考慮しながら、航路を進む。
4. 販売する：利益を得て、地域の市場を変動させる。
5. 再投資する：船をアップグレードしたり、倉庫を借りたり、仲介業者事務所を開設したりする。
6. アクセスを拡大する：信頼を築き、リスクを軽減し、契約やライセンスをアンロックする。
7. 商業的な目標を達成する：あなたが築き上げたものに基づいて、4つの異なる勝利ルートが存在する。

## 船長の種類

| 船長 | 特徴 | 利点 | 欠点 |
|---------|----------|------|-----------|
| **Merchant** | ライセンス付きの交易業者、地中海を拠点 | 価格が有利、検査の頻度が低い、信頼が築きやすい | 闇市場へのアクセス不可 |
| **Smuggler** | 秘密主義の取引業者、西アフリカを拠点 | 闇市場へのアクセス可能、高級品の取引、違法取引 | リスクが高い、検査の頻度が高い |
| **Navigator** | 探検家、地中海を拠点 | 船が速い、航続距離が長い、東インドへのアクセスが早い | 初期の商業的地位が弱い |

## システム

**経済:** 10の港、8種類の貨物、17の航路における需給に基づいた価格設定。大量の供給による価格暴落を防ぐペナルティ。市場の変動が地域に機会をもたらす。

**航海:** 嵐、海賊、検査などを含む、数日間の航海。食料、船体、乗組員は重要な資源。

**船長:** 8〜20%の価格差、独自の開始位置、異なるアクセス権を持つ、3つの異なるタイプ。

**契約:** 信頼と実績によって制限される、6種類の契約。供給元の情報が検証された配達。期限があり、結果も伴う。

**評判:** 地域での評判、港ごとの評判、税関の監視、商業的な信頼。アクセスを制限したり、開放したりする多角的なシステム。

**インフラ:** 倉庫（3段階）、仲介業者事務所（3つの地域に2段階）、購入可能なライセンス5種類。それぞれが取引のタイミング、規模、またはアクセスを変化させる。

**保険:** 船体、貨物、契約保証。リスクに対する追加料金。保険金請求の承認または拒否。

**信用:** 金利、支払い期限、デフォルト時のペナルティを含む、3段階の信用システム。リスクを伴うレバレッジ。

**キャリア** — 6つのカテゴリに分けられた27の重要なステップ。キャリアプロファイルの解釈（主要/二次/新興タグ）。勝利への4つの道筋：合法的な貿易会社、影のネットワーク、広大な海洋ルート、そして商業帝国。

## 勝利への道筋

- **合法的な貿易会社** — 厳格な正当性。高い信頼性、高額な契約、清廉な評判、広範なインフラ。
- **影のネットワーク** — 秘密裏で利益の高い取引。監視下にある高利益率、リスク管理、強靭な運営。
- **広大な海洋ルート** — 長距離の商業力。東インドへのアクセス、遠隔地のインフラ、主要ルートの支配。
- **商業帝国** — 統合された多地域運営。すべての地域にインフラを構築、多様な収入源、金融力。

A trade-first maritime strategy CLI where you build a merchant career through route arbitrage, contracts, infrastructure, finance, and commercial reputation across a living regional economy.

## Why Portlight

Most trading games flatten trade into a number that goes up. Portlight treats trade as a commercial discipline:

- **Prices react to your trades.** Dump grain at a port and the price crashes. Every sale shifts the local market.
- **Ports have real economic identities.** Porto Novo produces grain cheaply. Al-Manar consumes silk hungrily. These aren't random — they're structural.
- **Voyages carry risk.** Storms, pirates, inspections. Your provisions, hull, and crew matter.
- **Contracts require proof.** Deliver the right goods to the right port with tracked provenance. No faking it.
- **Infrastructure changes how you trade.** Warehouses let you stage cargo. Brokers improve contract quality. Licenses unlock premium access.
- **Finance is leverage with teeth.** Credit lets you move faster. Default, and doors close.
- **The game reads what you built.** Your trade history, infrastructure, reputation, and routes form a career profile. The game tells you what kind of trade house you actually are.

## The Core Loop

1. Inspect the market — find what's cheap here and expensive elsewhere
2. Buy cargo — load your hold
3. Sail — cross routes under weather, crew, and provision pressure
4. Sell — earn margin, shift the local market
5. Reinvest — upgrade your ship, lease a warehouse, open a broker office
6. Build access — earn trust, reduce heat, unlock contracts and licenses
7. Pursue a commercial destiny — four distinct victory paths based on what you actually built

## Quick Start

```bash
# Install
pip install -e ".[dev]"

# Start a new game
portlight new "Captain Hawk" --type merchant

# Look at what's for sale
portlight market

# Buy cheap goods
portlight buy grain 10

# Check available routes
portlight routes

# Sail to where grain sells high
portlight sail al_manar

# Advance through the voyage
portlight advance

# Sell at destination
portlight sell grain 10

# See your trade history
portlight ledger

# Check your career progress
portlight milestones
```

See [docs/START_HERE.md](docs/START_HERE.md) for a guided first session and [docs/FIRST_VOYAGE.md](docs/FIRST_VOYAGE.md) for a detailed early-game walkthrough.

## Captain Types

| Captain | Identity | Edge | Trade-off |
|---------|----------|------|-----------|
| **Merchant** | Licensed trader, Mediterranean base | Better prices, lower inspection rates, trust grows faster | No black market access |
| **Smuggler** | Discreet operator, West Africa base | Black market access, luxury margins, contraband trade | Higher heat, more inspections |
| **Navigator** | Deep-water explorer, Mediterranean base | Faster ships, longer range, East Indies access early | Weaker initial commercial standing |

## Systems

**Economy** — Scarcity-driven pricing across 10 ports, 8 goods, 17 routes. Flood penalties punish dumping. Market shocks create regional opportunities.

**Voyages** — Multi-day travel with weather events, pirate encounters, inspections. Provisions, hull, and crew are real resources.

**Captains** — Three distinct archetypes with 8-20% pricing gaps, unique starting positions, and different access profiles.

**Contracts** — Six contract families gated by trust and standing. Provenance-validated delivery. Real deadlines with real consequences.

**Reputation** — Regional standing, port-specific reputation, customs heat, and commercial trust. A multi-axis access model that opens and closes doors.

**Infrastructure** — Warehouses (3 tiers), broker offices (2 tiers across 3 regions), and 5 purchasable licenses. Each changes trade timing, scale, or access.

**Insurance** — Hull, cargo, and contract guarantee policies. Heat surcharges. Claim resolution with denial conditions.

**Credit** — Three tiers of credit with interest accrual, payment deadlines, and default consequences. Leverage with real risk.

**Career** — 27 milestones across 6 families. Career profile interpretation (primary/secondary/emerging tags). Four victory paths: Lawful Trade House, Shadow Network, Oceanic Reach, and Commercial Empire.

## Victory Paths

- **Lawful Trade House** — Disciplined legitimacy. High trust, premium contracts, clean reputation, infrastructure breadth.
- **Shadow Network** — Profitable discreet trade. Luxury margins under scrutiny, heat management, resilient operations.
- **Oceanic Reach** — Long-haul commercial power. East Indies access, distant infrastructure, premium route mastery.
- **Commercial Empire** — Integrated multi-region operation. Infrastructure in every region, diversified revenue, financial leverage.

See [docs/CAREER_PATHS.md](docs/CAREER_PATHS.md) for detailed player-facing descriptions.

Uma estratégia marítima focada em comércio, onde você constrói uma carreira como mercador através de arbitragem de rotas, contratos, infraestrutura, finanças e reputação comercial em uma economia regional dinâmica.

## Por que Portlight?

A maioria dos jogos de comércio simplifica o comércio em um número que simplesmente aumenta. Portlight trata o comércio como uma disciplina comercial:

- **Os preços reagem às suas transações.** Despejar grãos em um porto faz com que o preço caia. Cada venda altera o mercado local.
- **Os portos têm identidades econômicas reais.** Porto Novo produz grãos a baixo custo. Al-Manar consome seda avidamente. Isso não é aleatório — é estrutural.
- **As viagens envolvem riscos.** Tempestades, piratas, inspeções. Suas provisões, casco e tripulação são importantes.
- **Os contratos exigem comprovação.** Entregue os produtos certos no porto certo, com rastreabilidade. Não é possível falsificar.
- **A infraestrutura muda a forma como você comercializa.** Armazéns permitem que você prepare a carga. Corretores melhoram a qualidade dos contratos. Licenças desbloqueiam acesso premium.
- **O financiamento é uma alavancagem com consequências.** O crédito permite que você avance mais rapidamente. Se você não pagar, as portas se fecham.
- **O jogo analisa o que você construiu.** Seu histórico de comércio, infraestrutura, reputação e rotas formam um perfil de carreira. O jogo lhe diz que tipo de empresa comercial você realmente é.

## O Ciclo Principal

1. Analise o mercado — encontre o que é barato aqui e caro em outro lugar.
2. Compre carga — carregue sua embarcação.
3. Navegue — atravesse rotas sob a pressão do clima, da tripulação e das provisões.
4. Venda — obtenha lucro, altere o mercado local.
5. Reinvista — atualize seu navio, alugue um armazém, abra um escritório de corretagem.
6. Construa acesso — ganhe confiança, reduza a atenção indesejada, desbloqueie contratos e licenças.
7. Siga um destino comercial — quatro caminhos distintos para a vitória, baseados no que você realmente construiu.

## Início Rápido

```bash
# Install
pip install -e ".[dev]"

# Start a new game
portlight new "Captain Hawk" --type merchant

# Look at what's for sale
portlight market

# Buy cheap goods

## Tipos de Capitães

| Capitão | Identidade | Vantagem | Compromisso |
|---------|----------|------|-----------|
| **Merchant** | Comerciante licenciado, base no Mediterrâneo | Melhores preços, taxas de inspeção mais baixas, a confiança aumenta mais rapidamente. | Sem acesso ao mercado negro. |
| **Smuggler** | Operador discreto, base na África Ocidental. | Acesso ao mercado negro, margens de produtos de luxo, comércio de contrabando. | Maior atenção indesejada, mais inspeções. |
| **Navigator** | Explorador de águas profundas, base no Mediterrâneo. | Navios mais rápidos, maior alcance, acesso precoce às Índias Orientais. | Status comercial inicial mais fraco. |

## Sistemas

**Economia** — Preços determinados pela escassez em 10 portos, 8 produtos, 17 rotas. Penalidades por excesso de oferta punem o despejo. Choques de mercado criam oportunidades regionais.

**Viagens** — Viagens de vários dias com eventos climáticos, encontros com piratas, inspeções. Provisões, casco e tripulação são recursos reais.

**Capitães** — Três arquétipos distintos com diferenças de preços de 8 a 20%, posições iniciais únicas e perfis de acesso diferentes.

**Contratos** — Seis famílias de contratos bloqueadas por confiança e reputação. Entrega com rastreabilidade validada. Prazos reais com consequências reais.

**Reputação** — Reputação regional, reputação específica do porto, atenção indesejada alfandegária e confiança comercial. Um modelo de acesso de vários eixos que abre e fecha portas.

**Infraestrutura** — Armazéns (3 níveis), escritórios de corretagem (2 níveis em 3 regiões) e 5 licenças compráveis. Cada um altera o tempo, a escala ou o acesso ao comércio.

**Seguro** — Apólices de garantia de casco, carga e contrato. Taxas de atenção indesejada. Resolução de sinistros com condições de negação.

**Crédito** — Três níveis de crédito com juros, prazos de pagamento e consequências de inadimplência. Alavancagem com risco real.

**Carreira** — 27 marcos em 6 áreas. Interpretação do perfil de carreira (tags primárias/secundárias/emergentes). Quatro caminhos para a vitória: Casa Comercial Legal, Rede Sombria, Alcance Oceânico e Império Comercial.

## Caminhos para a Vitória

- **Casa Comercial Legal** — Legitimidade disciplinada. Alta confiança, contratos premium, reputação impecável, ampla infraestrutura.
- **Rede Sombria** — Comércio discreto e lucrativo. Margens de lucro elevadas sob escrutínio, gerenciamento de riscos, operações resilientes.
- **Alcance Oceânico** — Poder comercial de longo alcance. Acesso às Índias Orientais, infraestrutura distante, domínio de rotas premium.
- **Império Comercial** — Operação integrada em múltiplas regiões. Infraestrutura em todas as regiões, receita diversificada, alavancagem financeira.

## Status Alpha

Portlight está em fase alpha. Os sistemas principais estão completos e foram testados sob carga, mas o equilíbrio está sendo ajustado ativamente.

**O que está funcionando:**
- Todos os sistemas funcionais de ponta a ponta
- 609 testes em 24 arquivos
- 14 invariantes entre sistemas aplicadas sob 9 cenários de teste complexos
- Sistema de balanceamento com 7 bots de política em 7 pacotes de cenários

**O que está sendo ajustado:**
- Escalonamento de contrabandistas (atualmente com desempenho abaixo do esperado na progressão da embarcação)
- Concentração de rotas no Mediterrâneo (Porto Novo / Silva Bay dominam o tráfego)
- Taxas de conclusão de contratos (falhas na lógica de entrega em execuções automatizadas)
- Adoção de seguros (atualmente próxima de zero em testes simulados)

Consulte [docs/ALPHA_STATUS.md](docs/ALPHA_STATUS.md) para detalhes e [docs/KNOWN_ISSUES.md](docs/KNOWN_ISSUES.md) para problemas específicos.

## Segurança e Dados

Portlight é um **jogo de linha de comando que funciona apenas localmente**. Não estabelece nenhuma conexão de rede durante o jogo. Dados acessados: arquivos de salvamento locais (`saves/`) e arquivos de relatório (`artifacts/`), todos em formato JSON no sistema de arquivos local. Não há senhas, credenciais, telemetria ou serviços remotos. Não são necessárias permissões elevadas. Consulte [SECURITY.md](SECURITY.md) para a política completa.

这是一款以贸易为核心的海上策略游戏，您将通过路线套利、合同、基础设施、金融和商业声誉，在充满活力的区域经济中构建您的商业帝国。

## 为什么选择Portlight

大多数贸易游戏将贸易简化为单纯的数字增长。Portlight 将贸易视为一种商业纪律：

- **价格会根据您的交易而变化。** 如果您在一个港口大量倾销粮食，价格就会暴跌。每一次销售都会影响当地市场。
- **每个港口都有独特的经济特征。** 波尔托诺沃（Porto Novo）以低廉的价格生产粮食。阿尔-马纳尔（Al-Manar）渴望进口丝绸。这些并非随机现象，而是结构性的。
- **航行充满风险。** 遭遇风暴、海盗和检查。您的补给、船体和船员都至关重要。
- **合同需要提供证明。** 必须将正确的货物运送到正确的港口，并提供可追溯的来源证明。不能作弊。
- **基础设施会改变您的贸易方式。** 仓库可以帮助您储存货物。经纪人可以提高合同质量。许可证可以解锁高级权限。
- **金融是具有风险的杠杆。** 信用可以帮助您更快地发展。如果违约，您将失去一切。
- **游戏会根据您的成就进行评估。** 您的贸易历史、基础设施、声誉和航线将形成您的职业生涯档案。游戏会告诉您您实际上是哪种类型的贸易公司。

## 核心循环

1. 考察市场——找到哪里商品便宜，哪里商品贵。
2. 购买货物——装载您的船只。
3. 航行——在天气、船员和补给压力下穿越航线。
4. 销售——赚取利润，影响当地市场。
5.  reinvest——升级您的船只，租赁仓库，开设经纪人办公室。
6. 积累影响力——赢得信任，降低风险，解锁合同和许可证。
7. 实现商业目标——根据您的实际成就，选择四种不同的胜利路径。

## 快速开始

## 船长类型

| 船长 | 身份 | 优势 | 权衡 |
|---------|----------|------|-----------|
| **Merchant** | 持有许可证的贸易商，地中海为基地 | 更好的价格，更低的检查率，信任更容易建立 | 无法访问黑市 |
| **Smuggler** | 隐秘的经营者，西非为基地 | 可以访问黑市，享受奢侈品利润，进行走私贸易 | 更高的风险，更多的检查 |
| **Navigator** | 深海探险家，地中海为基地 | 船只速度更快，航程更远，可以更早地进入东印度群岛 | 初始商业地位较弱 |

## 系统

**经济**——在10个港口、8种商品和17条航线上，价格受稀缺性驱动。倾销会受到惩罚。市场波动会带来区域机会。

**航行**——多日航行，会遇到天气事件、海盗和检查。补给、船体和船员是真实的资源。

**船长**——三种不同的角色，具有8-20%的价格差异、独特的起始位置和不同的权限。

**合同**——六个合同类型，受信任度和声誉限制。提供可追溯的货物交付。有真实的截止日期和真实的后果。

**声誉**——区域声誉、港口特定声誉、海关风险和商业信任。一种多维度的权限模型，可以打开和关闭机会之门。

**基础设施**——仓库（3个等级）、经纪人办公室（3个区域的2个等级）和5个可购买的许可证。每个都会改变贸易的时机、规模或权限。

**保险**——船体、货物和合同保证保险。会收取风险附加费。解决索赔时会存在拒绝条件。

**信用**——三种等级的信用额度，带有利息、还款期限和违约后果。具有风险的杠杆。

**职业** — 涵盖6个领域，共27个里程碑。职业档案解读（主要/次要/新兴标签）。四种胜利路径：合法贸易公司、影子网络、海洋扩张、商业帝国。

## 胜利路径

- **合法贸易公司** — 严谨的合法性。高信任度、优质合同、良好声誉、广泛的基础设施。
- **影子网络** — 盈利的隐秘贸易。利润丰厚，但需谨慎，需要风险管理，具有韧性的运营。
- **海洋扩张** — 远距离的商业力量。可进入印度群岛，拥有远距离的基础设施，精通航线。
- **商业帝国** — 集成的多区域运营。每个区域都有基础设施，收入来源多元化，具有财务杠杆。

- **Data NOT touched:** No network connections, no remote servers, no cloud storage, no user analytics.
- **No secrets handling** — does not read, store, or transmit credentials, tokens, or keys.
- **No telemetry** is collected or sent. Zero network egress.
- **Permissions required:** Read/write access to the game directory for save files and report artifacts. No elevated permissions needed.
```

## Gate Rules

**Hard gate (A–D):** Must pass before any version is tagged or published.
If a section doesn't apply, mark `SKIP:` with justification — don't leave it unchecked.

**Soft gate (E):** Should be done. Product ships without it, but isn't "whole."

**Checking off:**
```
- [x] `[all]` SECURITY.md exists (2026-03-20)
```

**Skipping:**
```
- [ ] `[mcp]` SKIP: not an MCP server
```
```

title: Architecture
description: How Portlight is built — modules, data flow, and design principles.
sidebar:
  order: 5
---

## Stack

- **Python 3.11+** with Hatchling build system
- **Typer** for CLI commands
- **Rich** for terminal rendering
- Engine-first design: plain dataclasses, no ORM

## Module structure

```
src/portlight/
  engine/    — economy, voyage, contracts, reputation, infrastructure, campaign
  content/   — ports, goods, ships, routes, infrastructure specs, campaign thresholds
  app/       — Typer CLI (30 commands), Rich views, session manager
  balance/   — balance harness: policy bots, scenarios, runner, reporting
  stress/    — stress testing: invariants, scenarios, runner, reporting
  receipts/  — trade receipt schema and hashing
```

## Data flow

Every command goes through the **GameSession**, which mediates between the CLI and engine state:

1. CLI command calls session method
2. Session delegates to engine functions
3. Engine mutates dataclass state
4. Session auto-saves after every mutation

## Session advance tick order

Each day advances through a fixed sequence:

1. **Reputation tick** — heat decay
2. **Contract tick** — expiry, stale offers
3. **Infrastructure upkeep** — warehouse, broker, license deductions
4. **Credit tick** — interest accrual, due dates, defaults
5. **Market shift** — regional shocks
6. **Voyage events** — storms, pirates, inspections
7. **Campaign evaluation** — milestone checks
8. **Auto-save**

## Save format

JSON on the local filesystem. Returns 5-tuple:
`(WorldState, ReceiptLedger, ContractBoard, InfrastructureState, CampaignState)`

Backward compatibility via `.get()` defaults for new fields.

## Testing

- **609 tests** across 24 files
- **Balance harness** — 7 policy bots, 7 scenario packs, deterministic seeds
- **Stress testing** — 14 cross-system invariants, 9 compound scenarios
- **Invariant enforcement** — checked after every tick in stress runs
```

title: Career Paths
description: Victory paths and profile tags — what the game recognizes about your trade career.
sidebar:
  order: 4
---

Portlight doesn't ask you to pick a career path. It watches what you do and tells you what you built.

## Profile tags

Your career is scored across seven dimensions, each measured from actual game evidence:

| Tag | What it means | Key evidence |
|-----|---------------|-------------|
| **Lawful House** | Legitimate operator with institutional access | High trust, low heat, licenses, completed contracts |
| **Shadow Operator** | Profitable under scrutiny | High heat, luxury margins, survived seizures |
| **Oceanic Carrier** | Long-haul commercial reach | East Indies standing, distant infrastructure, galleon |
| **Contract Specialist** | Reliable deliverer | Contract completions, early bonuses |
| **Infrastructure Builder** | Multi-region commercial presence | Warehouses, brokers, licenses across regions |
| **Leveraged Trader** | Disciplined credit user | Borrowed and repaid without defaulting |
| **Risk-Managed Merchant** | Insured operations | Policies purchased, claims paid |

Each tag has a confidence level: **Forming**, **Moderate**, **Strong**, or **Dominant**.

## Victory paths

Four paths represent complete commercial identities. They require meeting multiple requirements simultaneously.

### Lawful Trade House
Disciplined legitimacy and premium access. High trust, clean reputation, premium contracts, broad infrastructure.

**Natural fit:** Merchant captain

### Shadow Network
Profitable discreet trade under scrutiny. High heat, luxury margins, survived inspections, came out ahead.

**Natural fit:** Smuggler captain

### Oceanic Reach
Long-haul commercial power. East Indies presence, distant infrastructure, premium route mastery.

**Natural fit:** Navigator captain

### Commercial Empire
Integrated multi-region operation. Infrastructure everywhere, diversified revenue, financial leverage. The hardest path.

**Natural fit:** No single type — requires sustained investment across every system.

## Diagnostics

Run `portlight milestones` to see:
- **Met** requirements (checked off)
- **Missing** requirements (with suggested actions)
- **Blocked** requirements (your choices make this path harder)
- **Candidate strength** (percentage toward qualification)

The first path completed is your primary victory. Additional paths can be completed for a broader legacy.

title: Getting Started
description: Install Portlight and play your first 10 minutes.
sidebar:
  order: 1
---

## Install

```bash
pip install -e ".[dev]"
```

Requires Python 3.11+.

## Start a new game

```bash
portlight new "Your Name" --type merchant
```

Three captain types are available:

| Captain | Edge | Trade-off |
|---------|------|-----------|
| **Merchant** | Best prices, lowest inspection risk, trust grows fast | No black market access |
| **Smuggler** | Black market access, luxury margins, contraband trade | Higher heat, more inspections |
| **Navigator** | Faster ships, longer range, East Indies access early | Weaker initial commercial standing |

Start with **merchant** for your first run.

## Your first trade

```bash
portlight market          # See what's cheap here
portlight buy grain 10    # Buy cheap goods
portlight routes          # Find where grain sells high
portlight sail al_manar   # Sail to a destination
portlight advance         # Travel day by day
portlight sell grain 10   # Sell at the destination
portlight ledger          # See your trade history
```

## What to focus on early

- **Profit per voyage.** Buy where stock is high, sell where it's consumed.
- **Provisions.** You consume one per day at sea. Buy before long voyages: `portlight provision 15`.
- **Ship condition.** Repair storm damage at port: `portlight repair`.

## What to ignore at first

- **Contracts** — wait until you understand route profitability
- **Infrastructure** — wait until you have 500+ silver and a steady income loop
- **Insurance and credit** — mid-game tools, not early priorities
- **Victory paths** — tracked automatically, check with `portlight milestones`

## System unlock timeline

| Silver | Day | What opens up |
|--------|-----|---------------|
| 0-500 | 1-10 | Basic trading, route discovery |
| 500-2000 | 10-25 | Ship upgrades, first warehouse, simple contracts |
| 2000-5000 | 25-50 | Licenses, insurance, credit, multi-region trading |
| 5000+ | 50+ | Victory path pursuit, full infrastructure |

description: Trade-first maritime strategy CLI — route arbitrage, contracts, infrastructure, finance, and commercial reputation.
sidebar:
  order: 0
---

Portlight is a trade-first maritime strategy game played in the terminal. You start as a captain with a small ship and limited silver, and build a merchant career through route arbitrage, contracts, infrastructure investment, financial leverage, and commercial reputation.

## What makes Portlight different

- **Prices react to your trades.** Dump grain at a port and the price crashes. Every sale shifts the local market.
- **Contracts require proof.** Deliver the right goods to the right port with tracked provenance.
- **Infrastructure changes how you trade.** Warehouses, brokers, and licenses aren't stat buffs — they change trade timing, scale, and access.
- **Finance has teeth.** Credit accelerates your moves. Default, and doors close.
- **The game reads what you built.** Your career profile emerges from evidence, not choices.

## The world

- **10 ports** across 3 regions (Mediterranean, West Africa, East Indies)
- **8 tradeable goods** with scarcity-driven pricing
- **17 routes** with distance-based travel
- **3 captain types** with distinct advantages and trade-offs
- **3 ship classes** from sloop to galleon
- **4 victory paths** representing different commercial identities

title: Trading Guide
description: Understanding the economy, finding profitable routes, and managing market dynamics.
sidebar:
  order: 2
---

## How prices work

Portlight's economy is scarcity-driven. Every port has goods it **produces** (high stock, cheap buy price) and goods it **consumes** (low stock, expensive buy price).

Your profit comes from buying where stock is high and selling where stock is low. The price difference minus port fees and travel costs is your real margin.

## Reading the market

```bash
portlight market
```

Key columns:
- **Buy price** — what it costs to purchase
- **Sell price** — what you'd get selling here (always lower than buy due to spread)
- **Stock** — current supply at this port

## Flood penalty

If you sell the same good repeatedly at the same port, a **flood penalty** appears: `(flooded: -25%)`. This reduces your sell price.

**How to manage it:**
- Diversify destinations — sell at different ports
- Diversify goods — don't carry only grain
- Wait — flood penalty decays over time

## Key trade routes

Prices are structural, not random. Some patterns:

- **Grain** is cheap at Porto Novo (produces it), expensive at Al-Manar (consumes it)
- **Timber** is cheap at Silva Bay, valuable at ports without shipyards
- **Silk and spice** offer high per-unit margins but are scarcer and attract inspection attention
- **Cotton** flows cheaply from West Africa, sells well in Mediterranean ports
- **Iron** exports from Iron Point at good margins

## Provenance

Every cargo item tracks where and when it was acquired. This matters for:
- **Contracts** — delivery must use cargo with tracked provenance from the right source
- **Inspections** — contraband cargo from suspicious regions draws more attention
- **Warehouses** — stored cargo preserves its provenance

## Ship upgrades

Three ship classes with increasing capability:

| Ship | Cargo | Speed | Cost |
|------|-------|-------|------|
| Sloop | Small | Slow | Starter |
| Brigantine | Medium | Moderate | ~2000 silver |
| Galleon | Large | Fast | ~5000 silver |

Check availability and prices: `portlight shipyard`

Upgrade when you can afford both the ship and the larger crew's daily wages.

"""Contract templates — 22 templates across 6 families.

Phase 1: 14 templates (grain, timber, iron, cotton, spice, silk, porcelain, rum)
Phase 2: +8 templates for new goods (tea, tobacco, dyes, pearls, weapons, medicines)
         and new regions (North Atlantic, South Seas)

Template design rules:
  - Every template creates a real trade decision (route, timing, cargo allocation)
  - Trust/standing/heat gates shape what each captain archetype sees
  - Captain bias weights make certain offers more likely for certain playstyles
  - Source constraints force multi-leg planning, not just dump-and-collect
  - Reward scaling rewards volume but deadline pressure rewards timing

"""Infrastructure content — warehouse tiers, broker offices, and licenses.

Design rules:
  - Depots are cheap enough to be a real early investment (day 10-20 range).
  - Regional warehouses are mid-game commitments (post first contract completion).
  - Commercial warehouses are late-game power (galleon-era capital).
  - Not every port gets every tier. Shipyard ports get commercial.
  - Upkeep is real — a forgotten warehouse drains capital.
  - Capacity is large enough to enable staging, not so large it bypasses timing.

Broker offices (3D-2A):
  - Region-level, 2 tiers each (local → established).
  - Each region has a personality: Mediterranean=lawful, West Africa=staples,
    East Indies=long-haul premium.
  - Offices improve board quality, market legibility, and trade terms.

Licenses (3D-2B):
  - 5 licenses gated by standing, trust, heat, and broker prerequisites.
  - Each unlocks premium contract families or formal access in a region.

"""Expanded route network — 5 regions, tiered access.

Route design creates five archetype tiers:
  Tier 1 (Sloop): Mediterranean and North Atlantic internal. Short, safe, low margins.
  Tier 2 (Brigantine): Cross-region bridges (Med↔WA, Med↔NA, WA internal).
    Medium distance, moderate risk. Bulk commodity routes become viable.
  Tier 3 (Galleon): Long-haul East Indies, South Seas, and cross-region shortcuts.
    High distance, high danger, but luxury margins justify the investment.
  Tier 4 (Man-of-War): Dangerous shortcuts and South Seas deep routes.

Hero's journey progression:
  Mediterranean → North Atlantic (early expansion)
  Mediterranean → West Africa (mid-game)
  West Africa → East Indies (late mid-game)
  East Indies → South Seas (endgame exploration)
  Direct long-haul shortcuts reward the bold

Cutter: nimble scout with moderate hold. Opens early cross-region runs.
  Fast enough to outrun pirates. Good crew-to-speed ratio.
Brigantine: balanced workhorse. Opens West Africa reliably and East Indies hub.
  More cargo = bulk routes viable. Higher crew = real wage pressure.
Galleon: slow fortress. Makes long-haul luxury profitable.
  Huge hold but expensive crew, slow speed means more provisions burned.

Man-of-War: endgame capital ship. Massive hold, maximum storm resistance.
  Eye-watering crew costs but opens every route in the game.

"""Infrastructure engine — commercial assets that change how trade is executed.

Warehouses, broker offices, licenses, insurance, credit all live here.
3D-1 ships warehouses. Later sub-packets add the rest.

Design law:
  - Every asset must change trade timing, scale, or access — not just buff a number.
  - Provenance is preserved through all storage operations.
  - Upkeep is real. Assets that aren't maintained decay or close.
  - Physical presence required: deposit/withdraw only when docked at the port.

Warehouse lifecycle:
  - lease_warehouse(state, port_id, tier) → opens a lease
  - deposit_cargo(state, port_id, captain, good_id, qty) → ship → warehouse
  - withdraw_cargo(state, port_id, captain, good_id, qty) → warehouse → ship
  - tick_infrastructure(state, day) → deducts upkeep, closes defaulted leases
  - warehouse_inventory(state, port_id) → read-only view of stored lots

"""Narrative engine — story beats, encounters, and quest hooks.

Narrative events are triggered by game state milestones and world conditions.
They don't replace the economy — they give meaning to commercial achievements.

Hero's Journey structure:
  1. The Call (first voyage, first trade)
  2. Crossing the Threshold (first new region)
  3. Tests and Allies (rival captains, mentor encounters, pirate threats)
  4. The Ordeal (storm survival, cargo seizure, near-bankruptcy)
  5. The Reward (first big contract, ship upgrade, reputation milestone)
  6. The Return (mastery, empire building, legacy)

Each narrative beat fires once per game and is tracked by ID.

### src/portlight/engine/reputation.py

```py
"""Reputation engine — the world's memory of the player's commercial behavior.

All standing/heat/trust mutations flow through this module. No other code
should directly mutate ReputationState dictionaries.

Canonical mutation points:
  - record_trade_outcome: after a profitable sell (the primary reputation driver)
  - record_port_arrival: when docking at a port
  - record_inspection_outcome: after an inspection event at sea
  - record_seizure: after cargo is confiscated
  - tick_reputation: daily time decay (heat cools, standing stabilizes)

Access effects:
  - get_fee_modifier: regional standing affects port fees
  - get_service_modifier: port standing affects local service costs
  - get_inspection_modifier: heat affects inspection severity
  - get_trust_tier: commercial trust tier for contract eligibility
