Updated protocol, API, installation, security, identity, and release documentation. npm 12+ is now required.
Note
High Risk
Changes contract publish authorization, P2P document handling, and new Bitcoin Taproot spend paths—security-sensitive areas that affect funds and mesh trust.
Overview
Adds contract Taproot tooling (contractTaproot, tier when predicates) plus Contract / FederationtoAddress / toTaprootContract so spend policies compile to deterministic P2TR ladders (failover, decay/migrate, PSBT prep). Introduces contract-scoped capability tokens (OP_CONTRACT_READ / OP_CONTRACT_SIGN), k-of-n ContractStateTip signing, and new shared CONTRACT_MESSAGE body types (group journal catch-up, capability grants, withdrawal request/witness).
Peer / wire:contract:message events now carry wireMessage / messageHex for journal attach; contract publish/patch allow-lists are tightened (wire signer must match body authority arrays; publisher no longer auto-granted). Document private relay gains _sendPrivateRelayedDocumentRequest; peeled/relayed document requests stay observe-only via delivery options. SIDECHAIN_STATE_PATCH gains optional patchesCanonical for multi-op RFC6902 fidelity; message decodeBody defaults missing optional fields.
Chores: root .npmrcallow-git=all and install reporting for npm 12+ GitHub consumers; developer docs note npm 12+ requirement.

The current head changes peer dialing and wallet lifecycle behavior, but unresolved issues can enable peer-address poisoning, retain sensitive key material after shutdown, and prevent recovery after failed wallet writes; security-sensitive files are also excluded from static analysis. These create concrete security, connectivity, and recovery risks, so the PR is not ready to merge without fixing or explicitly accepting them.

- Around line 79-94: Update normalizeLock’s CSV branch to reject block values
above 65535, returning null for any value outside the valid low-16-bit nSequence
range while preserving existing handling for positive in-range values.
- Around line 212-239: Update the tier validation loop around normalizeLock,
lockValue, and prevAfter so ordering comparisons are performed only when the
compared locks have the same lock type; otherwise reject the mixed ladder with a
clear error. Apply this to both the previous-tier after check and the
until-versus-after check, while preserving existing same-type ordering rules.
- Around line 59-73: Do not clamp thresholds to the number of unique keys. In
buildKOfNTapscript, validate the normalized threshold and throw when it exceeds
keys.length instead of lowering k; preserve the existing minimum-threshold
handling. Apply the same validation in normalizeContractSpendPolicy for thr so
duplicate-key policies cannot compile with a weaker quorum.

types/contract.js lines 340-364, extract the shared derivation into a protected
helper used by both classes and select one consistent default network instead of
the current regtest/bitcoin discrepancy.
- Around line 304-306: Update the csvBlocks fallback in the surrounding
federation configuration logic so settings.timeout is never converted directly
into a block count. Prefer the existing tap.DEFAULT_CSV_BLOCKS when csvBlocks is
unset, unless a clearly defined duration-to-block conversion is already
available; preserve explicit settings.csvBlocks handling.
- Around line 307-309: Update the custom spend-ladder branch in the relevant

In `@types/token.js`:
- Around line 100-102: Update the context selection in the Token signing flow to

Security review
Re-validated prior automation findings against HEAD a97e7523a (diff 214909a44…a97e7523a). Latest commit adds optional patchesCanonical on SIDECHAIN_STATE_PATCH plus message decode defaults.
No additional medium+ vulnerabilities identified in the new ARC/registry path: applyRegistryUpdateFields still requires caller-supplied fields and optional path policy; federation/auth gates are outside this helper. Peer contract:message now attaches wire hex for audit — not a new trust boundary bypass.
Note: Slack summary could not be posted — no Slack action is configured for this automation.
Lines 124-125 reject an empty catalogCanonical before the patchesCanonical branch runs. This conflicts with the patch-first design and forces patch senders to include unused catalog JSON. Validate catalogCanonical only after no patch sequence is supplied.

Re-validated prior automation findings against the current diff. Contract capability / taproot / peer self-dial changes were traced; no new medium+ vulnerabilities confirmed beyond the supply-chain issue below.
Open finding: 1 medium (npm allow-git=all).
Other candidate issues (CSV sequence encoding, CLTV height/unix boundary, catalog-required before patches) were treated as correctness/availability rather than exploitable auth/injection flaws for this review.

Security review (HEAD dba7d45c)
Re-validated prior automation findings and re-traced attacker-controlled inputs on the PR delta (peer contract auth, capability tokens, Taproot PSBT prep, sidechain registry apply, npm install trust).
Outcome: 2 Medium findings (re-confirmed supply-chain opt-out; new registry path-boundary regression). No High/Critical issues confirmed in this pass.
Checked and not reported as exploitable security issues here: CSV nSequence encoding (block-based BIP68 uses the low 16 bits without 0x00400000), legacy INVENTORY_REQUEST via generic carrier (documented intentional path), and unverified capability parse (now opt-in via allowUnverified).
Recent peer changes tighten boundaries (first-class opcode carrier block, contract publish signer must match authority arrays, peel/RELAY document requests stay observe-only). No new exploitable medium+ path found against this HEAD.

Security review (HEAD 5878630b)
Prior findings: The previous Medium issues (allow-git=all supply-chain relaxation; patchesCanonical/registry escape) are fixed in the current tree and were marked fully addressed.
Current: 1 High finding — unauthorized GroupChange membership mutation in the new multi-origin accumulate path. Details inline.
No Slack delivery channel is configured for this automation, so this GitHub review is the sole summary.
Two Medium issues remain with concrete attack paths on the current tip. Prior automation threads for the blinded-execution at finding were re-validated as still open; the earlier .npmrcallow-git=all supply-chain finding is fixed (default allow-git=none restored).
Findings
Medium — Blinded-execution at unbound by BIP340 decision signature (functions/blindedExecutionCircuit.js): first-delivery relay can fork coordinationRoot / hashlock.
Medium — Spoofed peering offer/announce pubkey triggers self-dial suppress (types/peer.js): mesh peer can block dials to chosen host:port for ~10 minutes (FIFO-capped).
No High/Critical findings in this pass. Other candidates (unsigned capability parse-only path, opcode allow-list empty = unrestricted, Taproot threshold clamp) were checked and either fail-closed, opt-in labeled, or lack a clear exploit path on tip.

Security review (HEAD 2e4d2ac75)
Re-validated prior automation findings against the current tip (peering self-suppress fix + federation ready-round retry).
Prior threads
Fixed: Spoofed peering pubkey → self-dial suppress. _enqueuePeeringCandidate now suppresses only when meta.verifiedPubkey (AMP signer) is local; advertised obj.pubkey is informational. Covered by tests/fabric.peer.js.
Still open: Blinded-execution at unbound by BIP340 (Medium). Same attack path as prior runs; still deferred in SECURITY.md / AUDIT.md / ARC §8 item 19.
This pass: No new medium+ issues in the federation finalize retry, tipSpendKeys empty-signers fix, or hallmark digest/magic hardening.
Outcome: 1 Medium remaining — request changes until at is bound in the decision signature or dropped from coordinationRoot.

Security review (HEAD 4ee885d7)
Re-validated prior automation threads and reviewed the new accumulate / governance commits (0f671acba, 4ee885d7).
Prior threads — the blinded-execution at bind is not addressed (still omitted from decisionSigningMessage; still folded into coordinationRoot). Earlier Highs (.npmrc allow-git, ingest fail-open, empty tip signers widening, unbound requestId, Beacon publish authorities, peering self-suppress) remain fixed on this tip.
Outcome: 1 High (new) + 1 Medium (re-validated).
High — GroupChangeProposal quorum bypass — foldProposals prefers attacker-supplied object.threshold over genesis/tip k-of-n, and auto-counts the AMP author as a voter. A single signer can adopt members.set / signers.set on a 2-of-2 (or k>1) contract.
Medium — Blinded-execution at unbound — relay can pair a valid party signature with an arbitrary first-delivery timestamp and diverge coordinationRoot / hashlock. Still deferred in AUDIT/SECURITY pending a protocol-string bump.

Security review (HEAD 3745041e3)
Re-validated prior automation threads against the wallet-lock / governance commit.
Addressed: blinded-execution decisionSigningMessage v2 now binds at; GroupChangeProposal quorum no longer accepts a proposer-chosen threshold below genesis/tip k-of-n.
Outcome: 1 High remains (residual of the prior governance finding).
High — members.set / signers.set omitted from the proposal vote signing string — BIP340 votes do not commit the roster arrays that foldProposals applies. A colliding id (last hash wins) can reuse honest votes to adopt a different signer/member set.
An advertised pubkey can suppress dialing a legitimate address.
Line 2303 calls _isOwnFabricPubkey(pubkey) on candidate.pubkey, then calls _suppressSelfDialAddress(addr). candidate.pubkey originates from meta.pubkey in _enqueuePeeringCandidate (line 1249), which is the attacker-controlled obj.pubkey from P2P_PEERING_OFFER.
_enqueuePeeringCandidate deliberately restricts suppression to meta.verifiedPubkey and states that obj.pubkey "must not poison dial targets for ~10 minutes" (lines 1231-1233). This path reintroduces exactly that poisoning: a remote peer advertises our own Fabric pubkey for a third-party host and we stop dialing that host.
Drop the candidate without calling _suppressSelfDialAddress when the match comes from an unverified advertised pubkey. Alternatively, carry verifiedPubkey on the candidate and suppress only on that value.
As per coding guidelines: "never assume remote input is trusted".
🔒 Proposed fix to limit suppression to verified keys
if (pubkey && this._isOwnFabricPubkey(pubkey)) {
this.emit('warning',
`[FABRIC:PEER] Dropping candidate ${addr}: pubkey is our own`);
- this._suppressSelfDialAddress(addr);+ // Advertised pubkeys are attacker-controlled; drop without a 10-minute+ // address suppression (see _enqueuePeeringCandidate).+ if (candidate.verifiedPubkey && this._isOwnFabricPubkey(candidate.verifiedPubkey)) {+ this._suppressSelfDialAddress(addr);+ }
if (this._candidateKeys) this._candidateKeys.delete(addr);
continue;

stop calls lockSession.lock(). That clears the idle timer and fires the lock listener. The listener is registered only in setWallet (line 938) and unlockWallet (line 204). A wallet loaded from this.seed, this.xprv, or a plaintext file has no listener, so stop leaves this.wallet populated and the key unwiped.
Call this.lockWallet() instead, which wipes the key directly and then locks the session.
This follows the coding guideline "clean up resources on stop".

sealedBlob.js is an at-rest encryption primitive, so its rejection paths matter as much as the happy path. The suite does not exercise these branches:
Tampered ciphertext must fail the GCM tag check with FABRIC_SEAL_DECRYPT.
iv of the wrong length must throw Invalid seal IV. (line 181).
ciphertext shorter than the tag must throw Invalid seal ciphertext. (line 182).

Consider adding async variants of sealJson and openSealedJson.
deriveKey uses crypto.pbkdf2Sync with 210000 iterations. That blocks the event loop for roughly 100-200 ms per call. The callers in this PR are CLI paths, so this is acceptable today.

clampLockTimeoutMinutes silently replaces bad input with the default.
A negative value or a non-numeric value returns DEFAULT_LOCK_TIMEOUT_MINUTES. An operator who types -5 in the TUI timeout prompt then gets 30 minutes with no message. The TUI reads back lockSession.timeoutMinutes and reports it, so the state stays visible, but the silent substitution is easy to misread. Consider documenting this in the JSDoc so callers know invalid input does not throw.

Remove the cross-repository require from this test.
The test loads ../../hub.fabric.pub/functions/documentInventoryMarket when that sibling checkout exists, and otherwise computes the markup inline.

SetupTui provides start() but no stop(). Teardown lives only in the local finish() closure inside _run, so no external caller can close the screen or remove the lock listener.

including the expected 10-sat fee, and preserve the invariant that the markup
spread covers that fee.
In `@tests/functions.fabricSetup.js`:
- Around line 14-21: Update isolatedEnv to return a cleanup function that stops
the environment before removing the temporary home directory. Invoke this
cleanup function from every test’s finally block, replacing direct
temporary-directory removal while preserving cleanup on both success and failure
paths.
In `@tests/functions.identityLock.js`:
- Around line 58-80: Extend the test for IdentityLock to assert snapshot() after
unlock, after touch, and after the automatic lock, verifying the expected
snapshot shape and deterministic remainingMs values from the injected fake
clock. Keep the existing event and lock-state assertions unchanged.
In `@tests/functions.sealedBlob.js`:
- Around line 54-68: Add tests in the sealedBlob test suite for tampered
ciphertext, invalid IV and ciphertext lengths, non-envelope input, and the nonce
alias using sealJson and openSealedJson; also cover out-of-range iterations for
both sealing and opening, asserting the documented errors or FABRIC_SEAL_DECRYPT
code.
In `@types/environment.js`:
- Around line 995-997: Update stop to call this.lockWallet() instead of invoking
this.lockSession.lock() directly, ensuring wallet key material is wiped for all
wallet-loading paths before the session is locked.
- Around line 203-210: Extract the duplicated lock listener registration into a
single _bindLockSession method containing the existing key.secure wipe and
wallet state updates, then call this method from both unlockWallet and
setWallet. Remove the inline duplicate registrations while preserving listener
replacement behavior and the current best-effort secure handling.
In `@types/setup.js`:
- Around line 37-49: Add an async stop() method to SetupTui that removes the
lockSession listener, destroys this.screen when present, and resolves any
pending start() promise. Refactor _run’s local finish cleanup to reuse this
lifecycle method, while preserving normal start() completion and making repeated
stop calls safe.
- Around line 58-65: Update the wallet unlock catch block in the setup flow to
retain the exception message instead of discarding it, storing it on the
instance such as _lastError. Surface that failure through _setStatus after the
render screen opens, and include the error in the non-render snapshot return
path while preserving retry behavior.

Security review (HEAD a85a372a8)
Re-validated prior automation findings against the current tip, including the open High on GroupChangeProposal vote binding.
Addressed since last review:signingStringForGroupChangeProposal v2 now includes canonical unique-sorted members / signers. foldProposals verifies BIP340 votes against that string, so a colliding proposal id cannot reuse honest votes on a swapped members.set / signers.set roster (covered by tests/groupChangeGovernance.test.js).
Still fixed (not re-reported):.npmrc keeps allow-git=none; accumulate ingest is fail-closed (signer/reader/capability); withdrawal requestId is bound; tip witness BIP340 + author bind; tipSpendKeys does not widen empty signers to members; Beacon/ARC CONTRACT_PUBLISH authority collection walks members.signers / spendPolicy.validators; blinded-execution decisions require BIP340 over decisionSigningMessage v2 (binds at) and hashlock+pubkey spend; contractTierWhen OPS is fail-closed; peering self-suppress uses verified AMP pubkey; ingest frame-size gate; proposal quorum cannot be lowered by an unbound proposer threshold.
This commit also: drops generic PASSWORD auto-unlock; fails closed on invalid --wallet paths; redacts /unlock from CLI history; rethrows wallet write errors instead of process.exit.
Outcome: No remaining high-confidence Medium/High/Critical findings on the current diff.

lockSession.lock() only wipes keys when _walletLockHandler was installed. loadWallet does not install that handler for seed, xprv, xpub, or plaintext wallets. Call lockWallet() so stop() wipes those wallet keys before it changes the status.

941-946: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win
A failed save leaves a zero-byte wallet.json that blocks the retry.
setWallet calls touchWallet() at line 946 before it writes any content. When no wallet file exists, touchWallet creates an empty file through fs.openSync(this.settings.path, 'wx') at line 767. If the write then fails, the catch at line 979 rethrows and the empty file stays on disk.
Two reachable failures hit this path:
sealJson at line 953 throws FABRIC_PASSWORD_POLICY for a password below the minimum length.
_writeWalletDocument throws ENOSPC or EACCES.
After either failure, walletExists() returns true. A retry without force then throws "Wallet file already exists." at line 945, and loadWallet reports the empty file as a warning with this.wallet = false. The user must delete the file manually.
Line 942 also assigns this.wallet = wallet before any validation, so this.wallet, walletPublic, and walletLocked describe a wallet that was never persisted.
Record whether the wallet file existed before the call. On failure, remove the file when this call created it, and restore the previous in-memory state.
🛡️ Proposed fix
setWallet (wallet, force = false, opts = {}) {
if (opts && typeof opts === 'object' && opts.force) force = true;

const password = opts.password != null ? String(opts.password) : '';

138-140: 🗄️ Data Integrity & Integration | 🔵 Trivial | 💤 Low value
The temporary filename is unique per process, not per instance.
${target}.${process.pid}.tmp collides when two Environment instances in one process write the same wallet path. types/cli.js line 29 constructs its own Environment, and scripts/fabric.js line 45 constructs another. If both save at once, one writeFileSync overwrites the other's temporary file, and the second renameSync fails or promotes partially foreign content.
Note that tests/fabric.environment.js lines 406 and 444 assert on the exact name ${walletPath}.${process.pid}.tmp. Those assertions must change to a directory scan for a .tmp suffix.

These assertions do not isolate the threshold guard.

Security review (HEAD 4d7351ee3)
Re-validated prior automation findings against the current tip, including the latest commit (password argv parsing + setWallet rollback).
Prior findings — still fixed (not re-reported):
.npmrc keeps allow-git=none
Accumulate ingest is fail-closed for signer mutations, GroupChat, and remaining types (verifyMessageSignature rejects a non-64-hex author before the publish signer gate)
Withdrawal requestId is bound; tip witness BIP340 + author bind
tipSpendKeys does not widen empty signers to members
Blinded-execution decisions require BIP340 over decisionSigningMessage v2 (binds at)
Peering self-suppress uses verified AMP verifiedPubkey only
GroupChangeProposal votes bind canonical members / signers (v2); quorum cannot be lowered by an unbound proposer threshold
patchesCanonical stays /registry-constrained; capability tokens require a verified issuer unless allowUnverified is explicit
This commit also: CLI --password stops at --, accepts -secret, and does not env-fallback when the flag is present; setWallet restores in-memory state and unlinks a placeholder wallet.json after a failed first save.

Blinded-execution unauthenticated accept + public hashlock preimage + unbound at — BIP340 v2 binds at; hashlock leaf is preimage+pubkey
Peering self-dial suppress via spoofed obj.pubkey — suppress uses verifiedPubkey only
GroupChangeProposal k-of-n bypass (threshold / unbound members/signers) — quorum is genesis/tip; vote string v2 binds rosters
Capability tokens still require a current-signer issuer and verified === true. Accumulate ingest now enforces MAX_MESSAGE_SIZE. Direct GroupChange remains signer-only per docs/ARC.md (k-of-n is the Proposal/Vote path).
Rename readCliPasswordFromArgv to a full name such as readCliPasswordFromArgumentVector. Rename argv and env to argumentVector and environment in the public signature. Update all callers and tests before external consumers adopt this export.
As per coding guidelines, “do not abbreviate in APIs; documentId should be documentIdentifier.”

Changes contract publish authorization, P2P document handling, and new Bitcoin Taproot spend paths—security-sensitive areas that affect funds and mesh trust.
Overview
Adds contract Taproot tooling (
contractTaproot, tierwhenpredicates) plusContract/FederationtoAddress/toTaprootContractso spend policies compile to deterministic P2TR ladders (failover, decay/migrate, PSBT prep). Introduces contract-scoped capability tokens (OP_CONTRACT_READ/OP_CONTRACT_SIGN), k-of-nContractStateTipsigning, and new sharedCONTRACT_MESSAGEbody types (group journal catch-up, capability grants, withdrawal request/witness).Peer / wire:
contract:messageevents now carrywireMessage/messageHexfor journal attach; contract publish/patch allow-lists are tightened (wire signer must match body authority arrays; publisher no longer auto-granted). Document private relay gains_sendPrivateRelayedDocumentRequest; peeled/relayed document requests stay observe-only via delivery options.SIDECHAIN_STATE_PATCHgains optionalpatchesCanonicalfor multi-op RFC6902 fidelity; messagedecodeBodydefaults missing optional fields.Chores: root
