Goal

Second step of #120 (socket options for std/network, FIRST-PARTY.md gap 22): a program can switch TCP_NODELAY and
turn TCP keepalive on, with its timings, on a connected TcpStream, and read both back. The runtime side landed in
step 1 (#426, the natives networkSetOption and networkOption, option numbers in docs/design/NETWORK.md section 4
and runtime/include/torb_network.h).

Design

Decided in #120 (comment decided by the loop); std/network, on TcpStream only, methods and no settings object:

  • fn setNoDelay(enabled: Bool): Result<Void, NetworkError> and fn noDelay(): Result<Bool, NetworkError>
    (option 0).
  • fn setKeepAlive(idle: Duration?, interval: Duration? = None, count: Int? = None): Result<Void, NetworkError>:
    None for idle turns keepalive off (option 1 = 0), Some(idle) turns it on (option 1 = 1) and sets the idle time
    (option 2); interval (option 3) and count (option 4) are set where given. Durations are whole seconds, at least
    1: a smaller non-zero Duration is rounded up to 1 s, a zero Duration or a count below 1 is refused with a
    NetworkError before any native is called.
  • fn keepAlive(): Result<Duration?, NetworkError>: None while keepalive is off, else the idle time.
  • Defaults stay: TCP_NODELAY on, keepalive off. A closed stream answers a NetworkError that isClosed().
  • Two private native fn declarations in std/network/src/tcp.trb next to networkShutdown, matching the manifest
    entries of step 1: networkSetOption(stream: Int, option: Int, value: Int): Int and
    networkOption(stream: Int, option: Int): Int; failures go through the existing NetworkError mapping.
  • No sandbox change: options of an already open socket are not a new capability (NETWORK.md section 10).
  • Not in this step: UDP options, listener options, SO_LINGER, Unix domain sockets (#119).

Acceptance criteria

  • The two setters and two readers exist on TcpStream in std/network/src/tcp.trb with doc comments, as above.
  • Tests in std/network/tests against a loopback connection: noDelay() is true by default, setNoDelay(false)
    reads back false and true again; keepAlive() is None by default, setKeepAlive(idle: Some(60.seconds()))
    reads back 60 s, setKeepAlive(None) turns it off; a sub-second idle is rounded up to 1 s; a zero idle and a
    count of 0 are refused; after close() every call fails with isClosed(). No assertion depends on a probe
    really being sent. Run natively and in the VM (the existing std/network test setup).
  • docs/standard-library/network.md documents the four methods; docs/design/NETWORK.md section 4 says the setter
    is done (replacing the "built in two steps" wording, keeping the option table); FIRST-PARTY.md gap 22 marked
    done with the date and a pointer to std/network/src/tcp.trb and the tests; the generated skills/ are
    regenerated (docs change).
  • Tier A green in forge CI (sh tools/gates.sh a); b if CLAUDE.md asks for it for the touched paths.

Seed

Touches the seed: no further seed change. This is the second commit of the two-commit rule of CLAUDE.md
("Seed and breaking changes"): the natives were taught in step 1, and the published seed c4a8443532aa (release
seeds, 2026-10-24) already contains them, so std/network can use them and the compiler (which imports std/network
in compiler/src/debugger/adapter.trb) still bootstraps in CI. No new native, no syntax change, no new driver flag, no
std name looked up by string by the compiler. A seed refresh after this is not needed for it and stays Torben's and the
merge gate's anyway.

Size

One PR, one commit: feat(network): TcpStream.setNoDelay and setKeepAlive (at most 100 characters). About 1 to 2 h:
~60 lines of std/, one test file, three doc edits.

Dependencies

Step 1 (#426) landed (PR #427). Independent of #119 (Unix domain sockets); both touch std/network/src/tcp.trb, so
whichever lands second rebases.

Source

## Goal Second step of #120 (socket options for `std/network`, FIRST-PARTY.md gap 22): a program can switch `TCP_NODELAY` and turn TCP keepalive on, with its timings, on a connected `TcpStream`, and read both back. The runtime side landed in step 1 (#426, the natives `networkSetOption` and `networkOption`, option numbers in `docs/design/NETWORK.md` section 4 and `runtime/include/torb_network.h`). ## Design Decided in #120 (comment `decided by the loop`); `std/network`, on `TcpStream` only, methods and no settings object: - `fn setNoDelay(enabled: Bool): Result<Void, NetworkError>` and `fn noDelay(): Result<Bool, NetworkError>` (option 0). - `fn setKeepAlive(idle: Duration?, interval: Duration? = None, count: Int? = None): Result<Void, NetworkError>`: `None` for `idle` turns keepalive off (option 1 = 0), `Some(idle)` turns it on (option 1 = 1) and sets the idle time (option 2); `interval` (option 3) and `count` (option 4) are set where given. Durations are whole seconds, at least 1: a smaller non-zero `Duration` is rounded up to 1 s, a zero `Duration` or a `count` below 1 is refused with a `NetworkError` before any native is called. - `fn keepAlive(): Result<Duration?, NetworkError>`: `None` while keepalive is off, else the idle time. - Defaults stay: `TCP_NODELAY` on, keepalive off. A closed stream answers a `NetworkError` that `isClosed()`. - Two private `native fn` declarations in `std/network/src/tcp.trb` next to `networkShutdown`, matching the manifest entries of step 1: `networkSetOption(stream: Int, option: Int, value: Int): Int` and `networkOption(stream: Int, option: Int): Int`; failures go through the existing `NetworkError` mapping. - No sandbox change: options of an already open socket are not a new capability (NETWORK.md section 10). - Not in this step: UDP options, listener options, `SO_LINGER`, Unix domain sockets (#119). ## Acceptance criteria - [ ] The two setters and two readers exist on `TcpStream` in `std/network/src/tcp.trb` with doc comments, as above. - [ ] Tests in `std/network/tests` against a loopback connection: `noDelay()` is true by default, `setNoDelay(false)` reads back false and `true` again; `keepAlive()` is `None` by default, `setKeepAlive(idle: Some(60.seconds()))` reads back 60 s, `setKeepAlive(None)` turns it off; a sub-second idle is rounded up to 1 s; a zero idle and a `count` of 0 are refused; after `close()` every call fails with `isClosed()`.
