doc/release-process.md says the artifact-signing public key MUST be
committed to the repo at release-pubkey.asc so verifiers can confirm
signatures. This was a documented gap that was never closed.
The key in question is the Krystie Triangles Release key (fingerprint
523A 8183 3EB7 2015 73E1 EFE1 DCF2 5799 6810 7984), which signs the
release artifacts in CI. v6.1.5 (and v6.1.4) artifacts were already
signed by this key; verifiers can now confirm against the key in
this file.
Verifying a v6.1.5 artifact:
gpg --import release-pubkey.asc
gpg --verify SHA256SUMS.asc
The maintainer's tag-signing key (Sami personal, 0x0BF7F8872FE0E859)
is NOT published here on purpose: that key is exported only to
release-pubkey.asc backup files (Sami's Dropbox / local backups).
The doc explains the two-key model.
The v6.x release line was missing from
packaging/appstream/org.cryptographic_triangles.TrianglesQt.metainfo.xml,
which means software centers (GNOME Software, KDE Discover, elementary
AppCenter, Flatpak, etc.) show the wallet as stuck at v5.3.7. bump-version.sh
flags this file as a manual follow-up; this commit closes that gap.
Skipped v6.1.2: that release was yanked (5c312bb published 2026-07-01,
superseded by 6.1.3) and the v6.1.3 changelog already documents the
replacement. Listing a yanked release would mislead users searching
for it.
The script previously assumed libtor.a and libi2pd*.a were already
present, but on a fresh checkout they only exist after running
src/tor/build-libtor.sh and src/i2p/build-libi2pd.sh. CI does this
in build-all.yml but local verification didn't, which bit me during
the v6.1.5 release.
Detect missing static libs and invoke the build scripts (passing
/usr paths for native Linux, matching what CI does). On a fresh
checkout this adds ~8 min to first-run verification; subsequent
runs skip the build step.
Logs go to /tmp/triangles-build-lib{tor,i2pd}.log for debugging.
Exit code 5 distinguishes build-prep failures from cmake/build
failures (3) and binary-compare failures (1/4).
Claude's 2026-07-07 audit of 2a4da33 (PoS reward rework) and 239cf61
(sigcache fix) concluded:
- 2a4da33 must stay reverted: chain-split risk, motivation gone
(a78a420 already relaxed the only test that cared), and the new
formula is worse than the old (drops fractional coin-age, int64
overflow risk on large coin-age). If exact proportionality is
ever wanted, it requires a height-gated hard fork.
- 239cf61 is safe to re-land: pure performance fix, no consensus
change, SHA256-collision false-positive risk is cryptographically
infeasible. Re-landed in PR #21 / fix/sigcache-false-positives
as a 6.1.6 candidate.
T024 in V6_TASKS.md records the rejection and the hard-fork
prerequisite for any future re-attempt.
The 2026-07-04 sigcache fix (239cf61, originally reverted, re-landed
here) changed the cache entry from a 64-bit XOR-mix to a uint256
SHA256(sighash || sig || pubkey). Default capacity is 200,000
entries, so peak memory grew from ~1.6 MB to ~6.4 MB. The stale
comment claimed 8 bytes per entry; correct that.
No code change — comment only. Confirmed via Claude's 2026-07-07
review of the reverted commits that re-landing 239cf61 is safe
(performance fix, no consensus change, SHA256 collision risk is
cryptographically infeasible).
Two stacked bugs in CSignatureCache:
1. Set() keyed on vchSig (with trailing hashtype byte) while Get() keyed
on vchSigCopy (without), so the cache never hit: a silent no-op.
(Found in prior audit session.)
2. Once (1) was fixed, the cache produced FALSE POSITIVES: the 64-bit
XOR-mixed key included the pubkey LENGTH but never the pubkey BYTES.
All compressed pubkeys are 33 bytes, so a signature validated once
hit the cache when re-checked against ANY other pubkey for the same
sighash — CheckSig returned true without verifying. A 2-of-3
CHECKMULTISIG could be satisfied by one valid signature duplicated.
This also masqueraded as first-match-wins multisig reordering in
multisig_tests/script_tests; those tests now pass with their original
strict assertions.
Cache entries are now the full SHA256 over (sighash || sig || pubkey),
matching upstream Bitcoin Core; false positives are cryptographically
infeasible.
36 commits since v6.1.4 (2026-07-04). User-facing:
- UI: olive-green for unconfirmed/immature stakes
- Wallet: close-hang on Windows from detached Tor/I2P threads fixed
- Consensus: live PoS checks during stale-tip IBD
Maintainer-visible:
- CHANGELOG.md added at the repo root
- doc/release-process.md corrected to match the actual signing keys
(RSA-4096 Krystie release key + Sami personal tag-signing key)
Pending and immature balance labels render in olive (#A8B847),
visually distinct from confirmed positive balances (#7CDB8A) while
still reading as 'incoming' rather than 'outgoing' (red).
* fix(wallet): prevent exit-hang on Windows from detached Tor/I2P threads
Embedded Tor and embedded I2P each ran on a background std::thread that was
.detach()'d at startup. The teardown paths (CTorEmbedded::Stop,
CI2PEmbedded::Stop) only flipped a running-flag — they did not signal the
thread to exit, and on Windows there is no signal mechanism in tor_api 0.4.x.
Result on Windows: when the user closed the wallet, Shutdown() completed its
bookkeeping and main() returned 0, but the process could not exit because the
detached thread was still in the Tor event loop / i2pd io_context. End Task
(TerminateProcess) was the only escape; the GUI appeared completely stuck.
Fixes:
- tor_embedded.h/.cpp: keep the Tor thread handle; Stop() now raise(SIGTERM)
on Linux, then joins the thread with a 5s timeout, then TerminateThread
(Win) / pthread_cancel + pthread_join (Linux) as a last resort.
- i2p_embedded.h/.cpp: same pattern — capture the bootstrap thread and join
it in Stop() with a 5s timeout fallback.
- init.cpp Shutdown(): spawn a 30s watchdog thread that calls ExitProcess(1)
if the graceful teardown takes too long. Belt-and-suspenders against any
future deadlock in the exit path.
- trianglesgui.cpp closeEvent(): second close attempt while the first
exit is still running immediately calls ExitProcess(2) / _exit(2).
User escape hatch when the graceful exit hangs.
All non-consensus (threading/process lifecycle only). Build via CI; not local.
Notes: notes/wallet-close-hang-fix-2026-07-07.md
* fix(i2p): drop leftover .detach() that broke build (lambda now joinable)
* fix(i2p): clean up after .detach() removal (trailing comment, blank line)
* fix(tor): MINGW std::thread is pthread-based, use pthread_cancel/join on MINGW
MINGW std::thread::native_handle_type is unsigned long long (pthread_t
emulation), not HANDLE. Mixing pthread handles with Win32
WaitForSingleObject/TerminateThread fails to compile on MINGW with
'invalid conversion' errors.
Use the same pthread_cancel/pthread_join path on Linux and MINGW; keep
TerminateThread only for MSVC builds where native_handle() returns a
real Win32 HANDLE.

Replace undefined signed shifts in SPHlib SIMD FFT arithmetic with bounded multiplications, handle empty vectors in base64/base32/base58/hash/script paths, and skip the DoS_checkSig microbenchmark threshold under sanitizer instrumentation.
Sanitizer ctest is now green locally, so make the GitHub sanitizer job blocking again.
Adds the infrastructure for verifiable Triangles releases:
- Reproducible builds (default-on): -ffile-prefix-map strips absolute
source paths from binaries; SOURCE_DATE_EPOCH pinned to commit
timestamp if env var not set. Two builds of the same commit with the
same flags now produce byte-identical binaries.
- scripts/verify-reproducible-build.sh: builds the daemon twice into
separate build dirs and compares SHA256. Pass/fail printed clearly.
- scripts/sign-release.sh: generates SHA256SUMS, writes detached .asc
signatures over each release artifact and over SHA256SUMS itself.
Supports --verify for independent third-party verification.
- release-process.md: canonical release pipeline documentation --
reproducibility properties, signing-key setup, distribution
requirements, failure-mode recovery, and the release checklist.
- scripts/README.md: updated to catalog the full scripts/ directory
(was previously scoped only to bump-version.sh).
Verified end-to-end on this branch:
- scripts/verify-reproducible-build.sh: exit 0, both builds SHA256
7a86d9659b7150f69dc53eb31cc4c7eb8df296b55fa889af5c5a1b310223c894.
- scripts/sign-release.sh: signs Release-built artifact, --verify
returns exit 0 (all sigs + checksums valid).
- ctest: 4/4 suites still pass with the new compile flags.
- Tamper test: modifying an artifact after signing causes --verify
to fail with '1 checksum(s) FAILED' (exit 1).
Existing signing key in the local keyring is used:

CI integration (separate PR): add a 'sign' job to build-all.yml that
imports GPG_PRIVATE_KEY from secrets and runs scripts/sign-release.sh
against the assembled release directory. Documented in release-process.md.
Documents:
- V5 soft-cap test coverage shipped on audit/kernel-coverage (ab0f4b4)
- PR #14 CI status: test-linux-unit PASS, sanitizer FAIL pre-existing
(simd.c:265 UBSan, separate workstream)
- Outstanding work prioritized for future sessions
- PR #14 is ready to merge
Documents:
- Hermes's 2026-07-04 handoff letter had a stale 'blocked on W2' framing;
W2/H4/W1 were already committed as 6cadf7f on 2026-07-02.
- This session's DoS_checkSig timing fix (commit b79e2b8): replaced the
nonsensical nManyValidate < nOneValidate comparison with a stable
per-verify bound (min of 3 trials after warmup, threshold 600ms
calibrated to ~1.6x observed p100 on DNS2).
- PR #14 CI status: 9 jobs in progress as of session end.
The previous timing assertion (nManyValidate < nOneValidate) was never
meaningful: the loops did different op counts (100 signs vs 500 verifies)
and the signature cache is intentionally a no-op on master, so cached-vs-
uncached verify cost is identical. The downgrade to BOOST_WARN_MESSAGE
that was on the branch fires every run.
Replace it with a real regression check: take the min of 3 timed batches
of 500 verifies after a warm-up pass, then assert the min is below an
empirically-calibrated threshold (600ms on this DNS2 dev box; real perf
~380ms in debug builds).
This catches genuine verify-path regressions (accidental O(n) cache key,
double-verify, hooking up OpenSSL instead of libsecp256k1) without
coupling to cache speedup that the on-chain code path explicitly avoids.
227/227 test cases pass, 21597/21597 assertions, 0 failures.
The hardcoded mapCheckpoints in src/checkpoints.cpp only covers heights
0..~17650 (the v5 hard fork pin). Everything from 17651 to current tip
(~2.2M blocks at the time of writing) runs full sigops/script/UTXO
validation in ConnectBlock. This is the actual sync bottleneck for new
nodes — days instead of hours.
The existing optimization (line 2179) skips input validation for blocks
at or below the last hardcoded checkpoint. This commit extends that
optimization with a ROLLING threshold: blocks at or below
nAssumeValidThreshold also take the fast path. The threshold advances
after each successful SetBestChain by ASSUME_VALID_BUFFER (100) blocks,
so the last 100 blocks are always fully validated — reorgs are caught
immediately.
Trust model:
- Hardcoded checkpoints: trusted at build time, source code is public.
Reproducible builds can verify.
- Rolling threshold: trusted because we validated it ourselves last
time. Same security guarantee as the static checkpoint, just newer.
- No master key, no centralized checkpoint authority, no new trust
anchor introduced. The chain itself is the proof.
Decentralization preserved: every node independently advances its own
threshold based on its own successful validation history. No coordination
required. A node that started from a different bootstrap will reach the
same threshold eventually.
Safety properties:
- ASSUME_VALID_BUFFER = 100 (matches MAX_REORG_DEPTH). A reorg that
rewrites within the buffer triggers full validation and rejection.
- Threshold only advances when NOT in IBD — we don\'t lock in a wrong
chain during initial sync.
- Threshold never decreases — reorgs can\'t accidentally lower the
fast-path boundary.
TODO before production deploy (called out in code comments):
- Persist nAssumeValidThreshold to wallet DB on shutdown so restarts
don\'t reset to 0 and re-validate 2.2M blocks.
- Add RPC: getassumevalidthreshold so operators can monitor.
crypter.cpp had zero tests despite guarding every encrypted wallet. Add
8 cases: passphrase round-trip for both KDFs (sha512 method 0 and scrypt
method 1), wrong-passphrase rejection, salt-affects-key, KDF determinism,
bad-parameter rejection (zero rounds / short salt / encrypt-before-key),
the EncryptSecret/DecryptSecret private-key path with a uint256 IV, and
ciphertext-tamper rejection. Round-trip/negative style, no brittle hard-coded
ciphertext. No implementation change (crypter.cpp is correct).
Note captured in the test: the wallet uses a uint256 as the AES IV but
AES-256-CBC consumes only the first 16 (little-endian) memory bytes -- a
subtlety worth remembering for anyone touching the key-encryption path.
Three coupled fixes to the test harness (no consensus/runtime code touched):
1. Root CMakeLists never called enable_testing(), so the top-level
build/CTestTestfile.cmake was never generated and "cd build && ctest"
(exactly what CI runs) discovered ZERO tests. The whole unit suite was
silently not gating CI; only the explicitly-invoked equivalence binary
ran. Add enable_testing() at the root so ctest finds all four test
executables.
2. chaindb_runtime_tests.cpp and snapshotnet_tests.cpp were compiled BOTH
into their own standalone executables AND into test_triangles via the
test/*.cpp glob. Each #defines its own BOOST_TEST_MODULE and redefines
the wallet/UI globals; the link only survived via
-Wl,--allow-multiple-definition, which silently drops duplicate module
and global symbols and can run those suites under the wrong fixture.
Exclude both from the glob (they already have dedicated add_executable +
add_test); nothing is lost and isolation is restored.
3. test_triangles TestingSetup opened the PRODUCTION chain DB at the default
datadir, so ctest failed (DB lock) on any host running a live daemon and
risked touching real chain state. Point -datadir at a fresh temp dir in
the fixture (mirrors the standalone DataDirSetup); cleaned up on teardown.
After: ctest -N lists 4 tests; ctest runs 100% green even with a live
trianglesd holding the default datadir.
With the signature-cache optimization intentionally left disabled (no
consensus-critical changes), cached and uncached verification cost the same,
so the nManyValidate < nOneValidate timing relation is not guaranteed. This
is a machine-dependent performance heuristic, not a correctness check, so
downgrade it from a hard CHECK to a WARN. CheckSig correctness is covered by
the multisig and script suites.
After reverting the consensus-affecting PoS reward rework, the original
truncating formula (nCoinAge * rate / 365 / COIN) is restored. It is not
exactly proportional at every boundary (r2 can be 2*r1 +/- 1 due to integer
truncation). That rounding is the on-chain behavior and must not be changed
in consensus code, so relax pos_reward_proportional_to_coinage to allow a
1-unit difference rather than demanding exact doubling. Test-only change.
The BIP39+BIP32 key derivation path (hdwallet.cpp) had zero tests despite
being security-critical and required to round-trip keys with the TRIdock
web wallet. Add canonical-vector tests:
- BIP39 Trezor english vector (mnemonic check + seed) and bad-checksum/
bad-word/bad-length rejection.
- BIP32 spec test-vector 1 (master + m/0H hardened child), verified
independently by base58-decoding the published xprv.
- DeriveTriangles determinism and index sensitivity.
No implementation changes: hdwallet.cpp derives correctly against the
canonical vectors.
ReorderTransactions called ListAccountCreditDebit("") which, after the
cursor-scan fix, returns only default-account entries. Entries booked to a
named account therefore kept nOrderPos == -1 forever and sorted incorrectly
in listtransactions. Use the "*" all-accounts sentinel, matching the
listtransactions RPC path and upstream Bitcoin.
Adds regression test acc_reorder_covers_named_accounts (fails on the old
code: named-account entry keeps nOrderPos == -1).
DO NOT MERGE without explicit sign-off. This changes GetProofOfStakeReward
rounding (round-half-up vs truncation, and whole-coin truncation of coin
age first). New formula can pay 1 unit more than the old one for some
inputs; un-upgraded nodes would reject such coinstakes — hard-fork risk.
The test-suite proportionality failures it addresses could instead be
fixed by relaxing the test. staking_tests expectations updated to match.

ListAccountCreditDebit kept the Berkeley-era early-break on the first
non-acentry record. The BDB cursor was sorted and pre-seeked to the
(acentry, account) prefix via DB_SET_RANGE, so breaking was correct there.
The SQLite cursor (SELECT key, value FROM main) scans the whole keyspace
in unspecified order, so the loop usually hit the version record first
and returned zero entries: every wallet silently lost its accounting
history in the UI. Skip non-matching records instead of breaking.
Fixes all 27 accounting_tests/acc_orderupgrade failures.
- Checkpoints_tests: align with the checkpoint map refreshed 2026-07-01
(2186940 pin superseded by 2205000/2206004 pins).
- wallet_tests: make abandon_not_from_me self-sufficient; add_coin() never
populated mapWallet, so the test provisions its own not-from-me tx.
- DoS_tests: RFC 6979 deterministic-signing fix (from prior audit session).
- http_seed_tests: correct chunked-body byte math in
dechunk_split_at_awkward_boundary (\r\r\n is 3 bytes, not 2).
- onion_v3_tests: .onion.onion fix (from prior audit session).
- time_drift_tests: post-fork drift limit is 90s (main.h), not 180s.
- consensus_safety_tests: new suite pinning consensus constants
(MAX_REORG_DEPTH, MAX_MONEY, fork heights, fee floors, etc.).
- CMakeLists: TEST_DATA_DIR definition quoting fix.
The QT wallet source used #f26522 (orange-red) for all UI accents
including tooltips, menus, scrollbars, messagebox borders, HD badge,
and embedded HTML link styling. The actual triangle logo on
cryptographic-triangles.org is #e32105 — confirmed by sampling the
PNG (mode color across 30% of pixels, matching the site's
<meta theme-color>).
This is a global, byte-for-byte replacement:
#f26522 -> #e32105 (1255 occurrences)
#61280E -> #3d0e04 (168 occurrences, re-derived hover/active shade)
Touches 99 files: 14 .cpp/.h, 22 .ui forms, 1 plugin .ui, 62 locale .ts.
The 'TRI brand color' comment in updateHDStatus() now references
#e32105 to match the canonical value.
Visual diff against pre-replacement wallet required before merge.
The hardened PowerShell retry loop from 2c2efd8 passed -ConnectionTimeout
and -OperationTimeout to Invoke-WebRequest. Those are PowerShell 7+ only;
GitHub Actions Windows runners ship PowerShell 5.1, which rejected them
with 'ParentContainsErrorRecordException / NamedParameterNotFound' on
the first iteration of the loop, and the catch block silently counted
the syntax error as a 'failed attempt' instead of a script bug.
Result on run #28689210122: both Windows jobs (build-windows-qt,
build-windows-daemon) failed at 'Download Tor' / 'Bundle Tor for daemon'
with exit code 1 before any HTTP traffic happened. macOS + Linux passed.
Fix:
* Drop -ConnectionTimeout and -OperationTimeout (PS7-only).
* Restructure the retry loop: explicit $downloaded flag, remove the
part-file on each attempt, throw explicitly at the end if all 3
attempts produced no usable file. The size check (>1MB) still
rejects 0-byte / truncated '200 OK' responses.
* Add a comment at the top of each step explaining the PS 5.1 limitation
so the next agent doesn't re-add the PS7 params.
The macOS build of e2cd0b6 (the NeedsBootstrap rocksdb/ fix) failed at
the 'Bundle Tor into app' step with bash exit code 6 after exactly 30s
of curl hanging against archive.torproject.org. All 4 Tor download
sites (Windows Qt, Windows daemon, Linux Qt .deb, Linux daemon .deb,
macOS Qt) used 'curl -sL' with no timeouts and no retries — a single
transient network drop from Azure westus to the Tor archive killed
the job.
Fix at all 4 sites:
* curl -fSL (HTTP error -> non-zero exit; fail loudly)
* --connect-timeout 15 / --max-time 120 (per-attempt bounds)
* --retry 3 --retry-delay 5 --retry-connrefused --retry-all-errors
(covers 5xx, DNS timeouts, and connection refused)
* 'set -euo pipefail' at script top so any failure aborts cleanly
* PowerShell variants get a manual retry loop with size check
(1MB minimum — a 0-byte '200 OK' response from a broken mirror
used to silently slip through)
Also bump CLIENT_VERSION_REVISION 1 -> 4 (v6.1.4) for the upcoming
release that will include e2cd0b6 (NeedsBootstrap rocksdb/ fix).
Release notes:
v6.1.4: Tor bundle download resilience (4 CI sites hardened)
+ e2cd0b6 (NeedsBootstrap rocksdb/ chain state detection). Supersedes
v6.1.3 only on CI reliability; no protocol/wallet/chain format changes.
The chain DB detection at src/bootstrap.cpp:51-61 checked for txleveldb/,
blocks/chainstate/, and chainstate/ — but not rocksdb/. After the LevelDB
to RocksDB migration completes on v6.1.x, the live chain state lives in
rocksdb/. If the legacy txleveldb/ directory is removed (a reasonable
cleanup operation now that the migration is done), the boot path
incorrectly decides 'no blockchain data found' and triggers a 943 MB
bootstrap download over Tor. DNS2 incident 2026-07-03: 5-hour wedge from
exactly this; recovery via v3 snapshot drop + rm -rf rocksdb + restart.
Add fs::exists(dataDir / "rocksdb") to the OR-chain so a fully-migrated
node stays recognized as 'has chain DB' even after txleveldb/ cleanup.
The four states this handles correctly:
- Fresh node (no chain DB): bootstrap → snapshot → load
- Mid-migration (txleveldb + no rocksdb): don't bootstrap, migrate
- Post-migration (both): don't bootstrap, load RocksDB
- Post-cleanup (rocksdb only, the broken case before this fix): now
correctly recognized as 'has chain DB' — don't bootstrap, load RocksDB
Ref: references/needsbootstrap-rocksdb-gap-2026-07-03.md (full incident
notes, recovery recipe, defense-in-depth notes on the auto-snapshot
loader at init.cpp:1260 which is already backend-aware).
The cherry-pick of updateHDStatus/updateI2PAddress from master left the
TrianglesGUI ctor without the corresponding label_hd / label_i2p /
label_i2p_icon / label_tor_icon wiring, and trianglesgui.h missing the
function declarations. Master compiles because all four exist together.
Add the constructor blocks guarded by findChild so they no-op on
hd-on-master's narrower UI (these widgets aren't added yet) and just-
work when master merges in the I2P-UI work. Add the missing function
declarations to the header.
