- README.md: drop "first Sulkta Rust project — workout for crafting-
table's Rust toolchain" paragraph + the `crafting-table build aldabra`
recipe. Both reference non-public Sulkta-internal infrastructure.
- Dockerfile: drop "Built nightly on Lucy (see lucy-infra/scripts/
nightly-builds.sh)" comment + the `lucy-registry:5000/aldabra/mcp`
internal image-name advertisement.
- Cargo.toml: drop the comment block referencing the deleted
`docs/internal-build-rewrites.md` + `crafting-table + Lucy + dev
hosts` Sulkta-internal-builds note. The patch block stands on its
own.
GitHub is canonical for aldabra now (per 2026-05-10 architecture call —
Gitea is a pull-mirror cache, not a forge we publish to). Build process
fetches pallas direct from github.com, no rewrite needed.
- Dockerfile: drop the `--mount=type=secret` git_credentials dance + the
url.insteadOf rewrite. cargo fetches pallas straight from
github.com/Sulkta-Coop/pallas at the locked SHA. No secret needed.
- docs/internal-build-rewrites.md: removed. The rewrite was the entire
reason for the doc, and the rewrite is gone.
Internal builds (Lucy / crafting-table / dev hosts) still hit
github.com for pallas, same as external builds. One extra WAN hop per
crate, but consistent everywhere and no environment-specific config.
Cargo.toml + Cargo.lock now point at https://github.com/Sulkta-Coop/pallas
for the pallas-fork patch entries. External clones from either public
mirror (github.com/Sulkta-Coop or gitlab.com/sulkta) build out of the box
— no LAN access needed.
Sulkta-internal builds short-circuit to LAN gitea via a `git config
url.X.insteadOf` rewrite on each host. Symmetric: covers both github and
gitlab → gitea. Same locked SHA either way; routing is environment-level,
not source-of-truth. See docs/internal-build-rewrites.md.
Dockerfile build-time rewrite also flipped to take public-URL inputs;
uses `gitea.sulkta.lan` instead of the bare LAN IP.
Two HIGH validator-side bugs + several MED/LOW off-chain issues found
in the subagent-driven audit on this branch. New validator hash:
a8081acef26935d9b5f44b92052178e17301b6d6e6808c91c5b56f5d.
## HIGH-1: Deposit redeemer let depositors drain tokens
aiken-escrow/validators/escrow.ak Deposit branch now requires
`value_geq_value(new_value, in_value)` before computing net_added.
Previously net_added could carry negative quantities (when new_value
< in_value component-wise), letting a depositor write a matching
new_d.deposits with reduced values and pocket the difference as
wallet change. Latent under v1 ADA-only MCP usage but the validator
must hold against all callers.
## HIGH-2: Empty/partial deposits enabled funds drain via Veto/Refund
Veto and Refund branches now require
`value_eq(deposits_to_value(d.deposits), in_value)` — the tracked
deposits must account for the full locked value. Previously
`refund_outputs_satisfy(_, [])` was vacuously true on empty deposits,
so a driver could fire Veto/Refund on an escrow opened with
`initial_contributor=None` (deposits=[], in_value>0) and pocket the
input's lovelace as change.
Defense in depth: escrow_open builder now refuses
`initial_contributor=None`. New helper `deposits_to_value` folds
deposit FlatValues into a Value via `assets.add` for the equality
check.
## MED: off-chain fixes
- escrow_open min-utxo bumped 1M → 2M (Conway-era inline-datum
+ script-address outputs need ~1.4-1.7 ADA, NOT the 1 ADA default).
- escrow_settle_unsigned + escrow_refund_timeout_unsigned now derive
`validity_lower_ms` via slot_to_posix_ms(network, slot) instead of
Koios's `block_time*1000` — the chain reconstructs `lower` from the
slot, so Koios's ~1s drift could pass off-chain preflight while the
chain rejects at the strict-`>` boundary.
- escrow_open_unsigned MCP tool no longer accepts (and silently
discards) `fee_lovelace` — the unsigned-tx builder auto-estimates.
## LOW: defensive depth
- escrow_veto + escrow_refund_timeout: `qty as u64` → `u64::try_from`
so a corrupt or adversarial datum with negative i128 qty can't slip
through with a wraparound.
## Tests
- 36 escrow builder tests pass (added rejects_no_initial_contributor)
- 132 dao tests pass under --features escrow_wip
- aldabra-mcp release build clean
## Infra
- Validator artifact files (plutus.json, validator.cbor.hex)
regenerated. Dockerfile already wired to bake them at
/etc/aldabra/escrow/ for MCP tools' validator_script_path arg.
- Internal audit findings written up at
audits/2026-05-09-escrow-internal-audit.md including the v2-deferred
items (multi-asset spend-input, lovelace-not-cross-checked, etc.)
Third-party audit still required before any mainnet deployment.
The pallas patch in [patch.crates-io] is now ssh://git@gitea after the
2026-05-06 token-scrub. Inside a docker build the rust container has no
SSH key and no known_hosts for gitea, so cargo's libgit2 / system-git
both reject the fetch.
Mount /root/.git-credentials as a BuildKit secret (mode=0400, required)
and set a build-time `url.HTTP.insteadOf SSH` rewrite. Cargo.toml and
Cargo.lock keep their SSH URLs — the rewrite is git-CLI-level so no
credential ever lands in the lock file or in any image layer.
Build invocation:
docker build --secret id=git_credentials,src=<creds-file> ...
where <creds-file> is one line `http://USER:PAT@192.168.0.5:3001`.
This mirrors the pattern crafting-table already uses on its runner
(.git-credentials + url.insteadOf rewrite). nightly-builds.sh on Lucy
will need an analogous --secret arg before it can rebuild this branch.
end-to-end working wallet: paste 24-word mnemonic, age-encrypt at rest,
on unlock derive root + payment + stake keys, build cip-19 base address,
serve four tools over mcp stdio (wallet.address, wallet.network,
wallet.balance, wallet.utxos).
deps added: ed25519-bip32 0.4 (pallas only ships raw ed25519, not the
cardano variant of bip32 hd derivation), cryptoxide 0.4 for pbkdf2-hmac-sha512,
age 0.10 for at-rest mnemonic encryption, rpassword 7 for tty-only passphrase
prompts, toml 0.9 for config.toml.
new modules:
- crates/aldabra-core/src/derive.rs — payment + stake key derivation, hash
- crates/aldabra-chain/src/koios.rs — real reqwest impl, asset aggregation
- crates/aldabra-mcp/src/{bootstrap,config,tools}.rs
caught one bug pre-flight: get_balance was clobbering same-asset
quantities across utxos instead of summing. fixed + regression test.
headless support via ALDABRA_PASSPHRASE env (mcp clients own stdin so
the rpassword prompt path can't run). docker secret / systemd
EnvironmentFile sources it in production.
dockerfile: multi-stage rust:1.95-bookworm → debian:bookworm-slim, tini
as pid1, non-root aldabra user, /var/lib/aldabra owned 700.
29 unit tests + 1 ignored live-koios test. preprod smoke test exercised
initialize → tools/list → tools/call wallet.address end-to-end via
piped json-rpc; correct preprod address came back from canonical
abandon-art mnemonic.
phase 2 (send) is next.
