Zuse default-attach: xHCI initial-port-scan fix, ZUSEDISK wiring, mismatched-marker resync
xhci_bringup() now scans for already-connected ports at bring-up (xhci_scan_ports_for_already_connected()), not just later hotplug events, so a USB device present on the QEMU command line at launch is detected. Makefile.starkernel attaches disk/zuse.img on the xhci0 bus by default in all three arch qemu targets (ZUSEDISK=, empties for a bare boot). capsule_mint_identity() gained a drive_known_blank param to skip a fully redundant second homeblocks_sig_check() when the caller already confirmed HOMEBLOCKS_SIG_BLANK itself. Root-caused what looked like a hang after the drive attached: Artemis's fence still carried a genesis marker from before a mid-session reformat, while the reformatted disk/zuse.img read back BLANK -- a mismatched pair capsule_zuse_boot_try_attach() correctly declined to act on, leaving the boot idling at a plain ok> with nothing left to log (indistinguishable from a hang under slow TCG). Fixed by zeroing both disk/artemis.img and disk/zuse.img at their original sizes, giving a matched blank pair. Verified full three-architecture acceptance: amd64 fresh genesis-mint, aarch64/riscv64 clean reload against the same now-minted images.

Retire emergency CLI: Zuse goes thumbdrive-resident, ACL.4th activated
Three tightly-coupled changes, verified together per Captain Bob's own "getting rid of the emergency cli" direction: 1. Zuse's identity is thumbdrive-resident, never system-resident. New zuse_genesis_marker_t (magic/version/zuse_pubkey[32]/crc) replaces zuse_cert_devblock_t's slot in the top-of-device fence -- the system now remembers only that a root identity exists and its pubkey, never a seed. zuse_cert_devblock_t is kept in the repo, marked superseded, no longer written by any code path. capsule_mint_identity() grows a genesis mode (issuer_vm=NULL): no cert is built or written (Zuse isn't verified against a separate signer -- she's recognized by pubkey match against the marker) and two new optional out-params (out_pubkey/out_seed) let the caller install the cert immediately after a genesis mint. New capsule_zuse_boot_try_attach() (capsule_zuse_boot.c), called from sk_repl_idle() on every fresh USB attach (the only point in the boot lifecycle a thumbdrive can actually be detected -- attach polling doesn't exist yet at kernel_main.c's old one-shot mint point, which is why that whole block is gone): no marker + blank drive -> genesis-mint; marker present + matching drive -> read its own user_identity_seed_t, install the cert. Either way, re-runs ACL-ZUSE-BOOT (zuse.4th) so zuse_session activates exactly like it always has for a same-boot cert install -- ACL-PIN only blocks redefinition, not re-execution, so no new C-side auth logic needed. 2. ACL.4th activated (capsules/init.4th) -- inactive all session until now. Found and fixed a real bug this immediately surfaced: zuse.4th's ACL-ZUSE-BOOT tried `['] ACL-ZUSE-BOOT ACL-PIN` from inside its own still-compiling definition -- the word isn't findable yet at that point, so the whole definition silently failed to compile every previous boot this session (dormant, since ACL.4th never loaded). Fixed: pin after the definition closes, not from within it -- it only needs to happen once anyway, and pinning doesn't block the re-invocation genesis/attach needs. 3. The unauthenticated emergency-CLI ACL bypass is retired (repl.c): `emergency_console = is_hera ? (zuse_session ? 0 : 1) : 0` deleted from both sk_repl_step and sk_repl_run. Every word run from Hera's own bare prompt now goes through ordinary ACL enforcement; emergency_console is driven only by the genuine C-level fault handler again. Added ZUSE-SESSION? (starforth_words.c), a read-only diagnostic matching ZUSE-PUBKEY@'s own precedent, to verify the whole chain directly rather than by inference. Verified end-to-end live in QEMU: fresh boot, no thumbdrive -> ZUSE-SESSION? reads 0. Attach a genuinely blank drive via QMP -> genesis mint fires automatically (no typing) -> ZUSE-SESSION? reads -1 (true). Hermes/Artemis both birth clean on all three architectures with ACL now actually enforced for the first time all session -- no denials, no UNKNOWN WORD beyond the deliberate POST self-test cases.

MINT: parameterize with full name, username, email, phone
Extends user_identity_seed_t (version 2) with fixed-size full_name/ username/email/phone fields -- plenty of unused pad space (4016 bytes) was already there. Deliberately NOT encoded into the DER cert's Subject field: that would mean building a real X.509 RDNSequence (OIDs for commonName/emailAddress, PrintableString/UTF8String tagging), well past this project's own stated "deliberately not a general ASN.1/X.509 [builder]" scope. This human-readable profile data isn't security-relevant the way pubkey/serial are (the only two fields CERTVERIFY/BINDSTEP actually check) -- it travels alongside the keypair in the plain identity record instead. capsule_mint_identity() takes full_name/username (required, validated non-empty and within their fixed field widths) and email/phone (NULL or empty = null, matching the schema's own nullable convention). The MINT FORTH word's stack signature grows to 4 string pairs ( fname-c fname-u uname-c uname-u email-c email-u phone-c phone-u -- ok? ). Verified live in QEMU: minted two real identities with real profile data -- Zuse (full_name "Konrad Suse", username "Zuse", zuse@pantheon.org) onto disk/zuse.img, and a regular user (full_name "Captain Bob", username "CaptBob", capt.bob@pantheon.org) onto disk/user1.img -- then read the raw devblock bytes back off both images directly and confirmed every field byte-exact at its correct struct offset. Clean 3-architecture regression boot confirms no side effects. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_019ZGkimpfyh63EZyRkNbkPD |

Phase E: MINT -- real keypair, Zuse-signed DER cert, working default identity
capsule_mint_identity() (new capsule_mint.h/.c): mints a fresh identity onto a blank/unminted thumbdrive -- real Ed25519 keypair from virtio_rng, a fresh drive_uuid (independent random draw, not derived from the identity seed, per FABRIC-3.md §F.8 decision 3), a Zuse-signed DER cert in the CERTVERIFY format, and a small working default personality (a real WELCOME word, not a stub -- FABRIC-3.md §F.6/§F.8's own "default personality content" question stays open, but whatever mints today must actually do something when RUNCAP births it). Refuses to overwrite a drive that already reads as a recognized home-blocks drive, mirroring WRITE(10)'s own refuse-on-non-blank posture (decided now, not just "reasonable by analogy" as §F.8 left it). x509_build_user_cert() (x509_ed25519.h/.c): the encode-side counterpart to the existing decode functions (x509_extract_ed25519_pubkey(), x509_verify_signature(), x509_extract_serial()) -- a minimal DER TLV writer producing exactly the fields those functions read. Host-tested round-trip against the real decoder before trusting it in the kernel, including a high-bit-serial case that exercises the DER integer-padding rule; all assertions pass (pubkey/serial round-trip, signature verifies against the real issuer, correctly rejects the wrong key and a corrupted signature). New user_identity_seed_t (user_identity_seed.h): the on-disk record for a minted identity's own keypair, same magic+version+fields+pad-to-4096+ real-CRC convention as zuse_cert_devblock_t and homeblocks_sig_t. Fixed devblock layout: sig(1), cert(2), seed record(3), default personality(4). New MINT word (mama_forth_words.c) and a small accessor (sk_repl_get_attached_blk_dev(), repl.h/.c) exposing the currently attached USB device regardless of home-blocks recognition -- MINT's own target is a blank drive, which by definition never sets Phase D's sk_repl_get_homeblocks_dev(). Verified end-to-end live in QEMU: MINT on a genuinely blank test drive, then (after a detach/reattach so the sig cache picks up the fresh header -- a known workflow gap, not fixed here, flagged for whoever builds the real Console onboarding flow) RUNCAP birthed a VM from that drive's own newly-minted content, and VM-EXECing its WELCOME word printed the default personality banner. The full mint-to-birth Tripod identity flow works end to end for the first time. Clean 3-architecture regression boot confirms no side effects on normal boot.
