- wo_tls_server: the mirror of the client driver. parse ClientHello (pick
suite, extract x25519 share, echo session id; reject no-x25519/no-1.3),
build ServerHello, derive the role-symmetric keys, emit the encrypted
flight (EncryptedExtensions + Certificate + a signed CertificateVerify +
Finished), verify the client Finished, switch to application keys
- server_sign_cv signs the CertificateVerify with the phase-G1 primitives
(RSA-PSS or ECDSA-P256 + a minimal DER SEQ{r,s} encoder); parse_client_hello
+ build helpers reuse the file's wire reader/writer
- wo_tls_server_start builds the Certificate message from a cert chain +
private key (RSA n/d or EC scalar) + ephemeral; encrypt/decrypt over the
application keys
- KAT: loopback — our client driver against our server driver, EC then RSA
server identity, reaching ESTABLISHED with an app round-trip both ways.

KAT'd (RSA vs python from-spec; ECDSA vs RFC 6979 A.2.5). Remaining G1c

- wo_ecdsa_p256_sha256_sign: deterministic nonce (RFC 6979 HMAC-DRBG over
the key + message — no RNG, no nonce-reuse/bias risk), then r = (k*G).x
mod n and s = k^-1 (z + r*d) mod n
- constant-time in the secret: jmul_ct (double-and-add-always + point
cmov) for k*G, and bn_modexp_ct for k^-1 mod n and the affine inversion.
Known residual (documented): the ladder leaks k's leading-zero count (a
bit-length hint, not the key) — a complete-formula/Montgomery-ladder
upgrade is the named follow-up
- KAT: byte-for-byte vs the RFC 6979 A.2.5 P-256/SHA-256 vectors ("sample"
+ "test"), our sign verifies with our verify, determinism checked.

- wo_rsa_pss_sha256_sign: EMSA-PSS-ENCODE (RFC 8017 §9.1.1) + modexp with d;
caller supplies the salt (fresh in production; fixed makes the KAT
deterministic). Private key (n,d)
- KAT: deterministic sign vs a python from-spec oracle byte-for-byte

The outbound TLS 1.3 client wired into the VM (ids 115-117, WO_B_MAX->117):
- net.connect_tls(host,port)->Int: DNS + non-blocking connect+poll bounded
by WO_TLS_HANDSHAKE_MS (decision 5), then a blocking, SO_*TIMEO-bounded
hand-rolled handshake over the sans-io driver, then wo_tls_verify_chain
(chain + host + validity + basicConstraints/EKU) against the shard's
lazily-loaded read-only CA bundle (decision 4). Any failure traps WO_T_IO
loudly (decision 3). Returns the fd.
- net.read_tls / net.write_tls: application data over the parked data plane
(decision 1) — O_NONBLOCK + park on POLLIN/POLLOUT like net.read/write,
with record reassembly + leftover-plaintext + in-flight-record buffers in
the per-fd slot so a park/retry never re-seals or loses progress.
- per-shard wo_tls_conn slot table keyed by fd, no locks (one thread per
shard, the wo_child pattern; decision 2); net.close frees the slot;
wo_vm_destroy reaps all slots + the CA bundle. getrandom ephemeral.
- driver keeps the whole Certificate message + wo_tls_client_chain() so the
trust walk sees the full chain, not just the leaf.
- wiring: wob.h, loader.c arities, builtin.c dispatch (second net range),
types.ml (net.connect_tls/read_tls/write_tls), sysio.c impl.
Builds; full runtime suite 0 fail; woc builds. Live behaviour is the
Phase-4 gate (next commit).

(EKU), every server-sent issuer and the signing anchor must be a CA
(basicConstraints CA:TRUE) with a pathLenConstraint covering the
intermediates below it — stops a leaf masquerading as a CA
- gen_x509.py extended (folds in the wildcard leaf, adds EKU clientAuth-only,
EKU serverAuth, a non-CA intermediate + a leaf issued under it); vectors
regenerated
- KATs: extractors (test_crypto 104) + chain enforcement (test_tls 103) —
EKU serverAuth accepted, clientAuth-only rejected, leaf-under-non-CA
rejected though every signature verifies; existing chains still pass.

A reusable named Workflow (.claude/workflows/) that runs the
brainstorm-to-ready groundwork this repo does before any feature code:
- Understand: read the target story (or find the NEXT-PLAN target) +
scout relevant .dev/reference projects for the concern
- Analyze: one agent per reference project — how it handles the concern,
gaps vs our planned approach, recommendations (the fiber/Go step,
generalized)
- Audit: story-format/frontmatter/plans-no-raw-code + dependency-graph /
status-board consistency
- Consolidate: settle open forks (KISS defaults), fold reference gaps as
locked requirements, acceptance-criteria gaps, go/no-go on readiness
Parameterized via args {story?, concern?, references?}; grounds every
agent in on-disk files. Does the parallelizable research half; the
fork-settling stays an interactive brainstorm. Invoke:

Compared §F3c-net's forks against gofiber v3's client (fasthttp + Go
crypto/tls/x509, .dev/reference/fiber). Two gaps my defaults had vs Go,
now locked as decisions 5 and 6:
- (5) bounded handshake deadline: the blocking model would let a stalled
server hang the shard's one thread indefinitely (the DoS DoTimeout
closes). connect_tls now bounds connect+handshake via non-blocking
connect+poll + SO_RCVTIMEO/SNDTIMEO, default WO_TLS_HANDSHAKE_MS
(10s); expiry traps WO_T_IO. _dl variant + park handshake stay follow-ups
- (6) chain hardening: signatures+validity+SAN alone let a leaf act as a
CA. Now every non-leaf must assert basicConstraints CA:TRUE (+pathLen)
and the leaf must carry EKU serverAuth — what Go's crypto/x509 enforces
- acceptance criteria added (stalled-server timeout; leaf-as-CA + no-EKU
rejected); connect_tls bullet, frontmatter review_pending, status NEXT

- locked: BOTH AES-GCM (128/256, TLS-mandatory per RFC 8446) AND
ChaCha20-Poly1305 (RFC 8439, easy constant-time, cookie default)
- AES constant-time via AES-NI/ARMv8 hardware + bitsliced software fallback
(compiler intrinsics, zero external dep)
- caller-supplied nonce (TLS builds its own per-record nonce); random-nonce
is a cookie WRAPPER (phase D) not the primitive. shape:
seal(key,nonce,aad,pt)->Bytes / open->?Bytes; AES variant by key length
- raw key + length check; hand-rolled (matches rv2 9); ids from 111
- phases A ChaCha -> B hardware AES-GCM -> C software AES -> D cookie wrapper
-> E gate (RFC 8439 + NIST GCM vectors, ASan, reference cross-check)
- risk/test: constant-time mandatory, KAT-gated, reused-nonce documented
- retires the stale "TLS proxy-terminated" OOS line (rv2 9 overturned it)
(cherry picked from commit c8a5a31c39a5d14952056cd0af1b8c1e42d4ed2d)
- decision: HAND-ROLL TLS 1.3 (no vendored lib) per developer call; keeps the
zero-external-dep single binary, and raises risk rather than lowering it —
recorded, owned, with mandatory mitigations
- 1.3-only; RSA-PSS/PKCS1 + ECDSA-P256 + full ASN.1/X.509 chain validation +
trust store + hostname (the scope needed to reach real LLM APIs)
- decomposed into a bottom-up phase ladder: A AEAD (=rv2 8, forces AES-GCM
there) -> B HKDF -> C X25519 -> D signatures/RSA -> E X.509 -> F record+FSM
client -> G inbound server; C/D/E may each split into own iterations
- risk + test strategy section: constant-time, reference-tested (openssl +
RFC 8448 vectors), negative tests first-class, no partial-trust states
- deps: rv2 8 (AEAD), lang 34 (SHA/HMAC), net.connect (110, landed). Board synced
(cherry picked from commit f1881cca8cd0cdd58b1ac844e3e3ea9c234bb99c)
- jarvis (00-story): 6th track, 2nd software built with writeonce — an AI
assistant; direct-HTTPS design; blockers named (net.connect + TLS)
- runtime-v2 7 observability + 8 symmetric cipher: moved from the language
track (were 30/43); 9 in-process TLS: created from the gap jarvis surfaces,
RETIRES the "TLS is the proxy's job" doctrine (both directions)
- language 41 (arena hang): fix design to ready — marshal cross-shard
messages (root), align the shard_id % nshards route/compare + assert bound;
poison-on-free + minimal fixture as follow-ups
- fiber scope-gap analysis (plan/exploration/fiber/01): porch vs fiber, what
porch lacks, would developers prefer porch
- board + dependency-graph synced (porch 2-8 ready; rv2 table; §5/§5a graphs)
(cherry picked from commit 203470ceb2a151fe3584931cd4237af3f96a9f29)
- new builtin net.connect(host, port) -> Int: the outbound-socket gap
language 38 named and jarvis surfaced; the client half of the net verbs
- getaddrinfo for DNS (v4/v6, numeric or hostname), blocking connect with
the same EINTR/stop handling as net.connect_unix, then O_NONBLOCK for the
park plane; returns the same fd-scalar accept yields
- wob.h enum + WO_B_MAX 110; types.ml registration; loader.c arity;
builtin.c sysio dispatch range extended to WO_B_NET_CONNECT; sysio.c impl
- verified: numeric IP + hostname (DNS) connect to a local listener, closed
port traps cleanly; ASan-clean; runtime battery 0 fail
- deferred (next slice): net.connect_dl deadline/park variant (no shard
stall during handshake), on the accept_dl pattern
(cherry picked from commit 13c6f124428243b4956fbb4eceb1e7d0206d45f2)
- whole porch track (2-8) now brainstormed and locked (all ready)
- four decisions: three hooks (on-listen/on-shutdown/on-route-registered);
healthcheck ships BOTH /livez + /readyz; directory listing off-by-default,
documented; Last-Modified via a new small time.utc(ms)->TimeParts builtin
- language enhancement: YES, one small builtin -- time.utc, a gmtime sibling
of time.local (time.local is local-tz, time.iso is UTC-but-ISO); IMS by
string-equality, no date parser. The track's third + smallest language touch
- byte ranges/large files via fs.read_at + iteration 6 writer; not lang-41-exposed
- track language bill now explicit: random_bytes (2), deflate+crc32 (7),
time.utc (8) -- each a builtin with a named consumer, none decoration
- validated against .dev/reference/fiber. Board: whole track marked ready
(cherry picked from commit 9801fceade799e25718606177f09e4306a579e98)
- five decisions: refuse incoherent heartbeat/idle_ms pair at construction;
codec = two C builtins deflate+crc32 (perf over pure-.wo; hand-rolled, no
zlib dep; gzip framing in .wo); ETag over uncompressed bytes + Vary;
Last-Event-ID explicitly unsupported (not silently ignored); Vary via
comma-join
- language enhancement: YES, two builtins -- the track's SECOND language
dependency after iteration 2's random_bytes. CRC32 finally gets its
consumer; inflate deliberately not built (request-body decompression OOS)
- corrected stale dependency: Vary uses iteration 5's comma-join, so story 7
depends on 6 + 5, NOT 2; codec is pure compute, not lang-41-exposed
- confirmed CRC32 absent + iteration 36 bit operators landed (pure-.wo was
viable, traded for hot-path speed)
- validated against .dev/reference/fiber. Board synced
(cherry picked from commit 07f53574dd90f502235b79d4920eab3d684c8b77)
- re-scoped to OUTBOUND streaming only
- three decisions: separate StreamHandler/BodyProducer parallel path (Resp
path untouched -> existing responses byte-identical); streaming routes opt
out of the after-chain, framework refuses at registration to combine with
header-mutating middleware (loud, never silent), security_headers() helper
lets handlers stamp them; chunked REQUEST bodies split into their own future
iteration (parse.wo refusal stays, smuggling cases enumerated for later)
- no language enhancement (net.write framing, fs.read_at/actor source,
interfaces for producer); rides the fiber loop not the actor pool, so not
lang-41-exposed
- fixed title inconsistency: "three iterations wait on" -> "two" (7 and 8)
- validated against .dev/reference/fiber + the app.wo/serve.wo pipeline. Board synced
(cherry picked from commit 15205408e03c3c02a38e00e5d2017a8a11f62f28)
- five decisions: head auto-registers with opt-out (+ patch/options/all);
request ids mirror limiter trust model with a NON-crypto source; per-route
body_limit is a SECOND check after routing (global BODY_MAX stays the
pre-routing ceiling, over-limit = 413); Route fields are corpus-free;
Vary accumulates by comma-join
- key finding: story 5 has NO upstream dependency, not even iteration 2 --
request ids are not secrets, so a non-crypto source (time.ticks+counter)
keeps it startable today; the one porch slice buildable right now
- three story assumptions corrected: per-route limit cannot replace the
global (body read before routing); the container-owned-move corpus fixture
has its OWN Route (adding fields is free); Vary needs no iteration 2
- validated against .dev/reference/fiber; zero language enhancement. Board synced
