Philes you can read, a save, and MTU that costs you something
Three holes closed:
philes — 40 written, all in src/philes.js so the next 160 is a writing
job and not a code job. P opens a reader: list on the left,
the text on the right, attributed to whoever wrote it in
whatever year they wrote it. Every level now drops at least
one; previously you collected files you could never open.
save — ESTABLISHED. Every hop writes level/ttl/hop/baud/philes/
cargo/flags to localStorage, and the boot screen offers
R — RESUME. A 64-hop game with no save is not a 64-hop game.
MTU — the HUD has been showing your MTU drop as you take files off
the board while nothing happened. Now two files are free and
after that you arrive in pieces, one TTL per extra fragment,
every hop. You can put things down again from the traceroute
map. Lore costs distance, which is the economy the whole
design is built on.
All 13 hops re-swept: clean.

Files taken off the BBS are lore, and lore is paid for in distance. Two is free;

## Skipped
|

|

- **Multiplayer (`CHECKSUM`)** — the Journey-style anonymous pass-by. Needs a server; add when there's something to connect to.
|
||||
- **MTU fragmentation** — BBS cargo lowers your MTU and it's on the HUD, but nothing splits you into two packets yet. Add when a level has a corridor narrow enough to need it.
|
||||
- **The 200 philes** — the collectible framework is live (`ctx.phile`, `HS.philes`) with ~20 written. The rest is a writing job, not a code job.
|
||||
- **Playing both fragments** — fragmenting costs TTL, it doesn't split you into two packets you alternate between. Add when a level has a corridor narrow enough to need it.
|
||||
- **The 200 philes** — 40 written in [`src/philes.js`](src/philes.js), all readable with `P`. Adding the next 160 is a writing job, not a code job: put the text in that file, call `ctx.phile('id')` wherever it should be found.
|
||||
- **Trade Wars** — the second door game. LORD is real and playable; TW2002 is "closed for maintenance since 1994", which is both a joke and true.
|
||||
- Levels are one hop's worth of content each, not the full 5–20 minutes the design doc describes. The genres, mechanics and set pieces are all in — the *duration* isn't.
