A restructure that + * deletes a file because no runtime path inside the repo reaches it will delete + * a module another service requires by relative path out of this checkout, and + * nothing here fails: the break lands in the sibling's CI, later, attributed to + * the sibling. Several modules in these services are exactly that shape. A file with no + * caller in this repo is therefore a CANDIDATE for deletion, and the sibling + * sweep is what turns a candidate into a verdict. + * + * THE FOUR REACHES, kept apart because they carry different weight: + * + * runtime the require closure of what the service actually starts: + * the Dockerfile CMD, and every `node ` an npm script runs. + * A file outside this closure cannot execute in production. + * tooling the closure of bin/, scripts/ and tools/: operator commands, + * verifiers, benchmarks. Real callers, not production ones. + * test the closure of test/. A file reached only from here exists to + * be tested and nothing else, which CODE-STYLE calls a signal that + * the file is dead rather than a reason to keep it. + * siblings any other repo naming the path, from bin/sibling-reference-map.js + * so the two tools can never disagree about what a reference is. + * + * A file outside all four is unreferenced across the platform and is the only + * shape a restructure here deletes outright. + * + * THE SIBLING REACH INCLUDES THE PLATFORM TOOLING, and it has to. The map tool + * sweeps the `xchain-*` siblings by default and treats the surrounding tree's + * tooling directories as OPT-IN, because those paths belong to the tree around + * this checkout rather than to this repo.

A grep run by hand finds the + * requires and misses the string literals, so the restructure needs ONE + * mechanical sweep whose output can be diffed before and after a move. A path + * that leaves this map without a matching edit in the referring repo is a + * broken sibling, and that break surfaces at the referrer's next CI run rather + * than at the commit that caused it. + * + * WHAT COUNTS AS A REFERENCE. Six shapes, reported as each site's `form`, + * because a rename tool has to find every one of them: + * + * text any literal run of `xchain-decoder/src/` in any text file: + * a relative require, a comment, a shell script, a markdown runbook. + * join a path built segment by segment, the shape + * path.join(root, 'xchain-decoder', 'src', 'foo.js'). When every + * segment after `src` is a literal the path is resolved; when one is + * a variable the site is reported under `dynamicReferences` instead, + * because a rename must be checked there by a human. + * root-var the checkout held in a variable and the file joined onto it: + * `const R = path.resolve(__dirname, '../../xchain-decoder')` then + * path.join(R, 'src', 'foo.js'), path.join(R, 'src/foo.js') or + * `${R}/src/foo.js`. The root may equally be + * process.env.XCHAIN_DECODER_PATH, a candidate array filtered to its + * first live entry, or a variable that points at `/src`. + * helper a closure that takes a repo-relative path and returns a file in + * this checkout, `decoderFile('src/rollback.js')`. A call over a + * literal array, `decoderFile('src/' + twin)`, is emitted once per + * element of that array. + * shell-var the same root-in-a-variable idea in bash, `"$VAR/src/foo.js"`. + * shell-arg the repo name passed as its own word with the path beside it, + * `copy_twin xchain-decoder "src/$f"`, resolved against the literal + * `for f in ...` list above it. The twin-copier script in the + * platform's tooling directories, reconcile-twins.sh, is built + * entirely out of this one and is wired into no CI. + * + * AND ONE THAT IS NEVER A PATH. A module loaded with `require('./' + mod)` over + * a literal list is named by no string at all, so a missed move can report a + * gate ABSENT rather than throwing. This repo builds no such require today, but + * the form is still detected, because the first one to land would otherwise be + * invisible: those sites are listed under `dynamicReferences` with the file list + * they resolve to, form `computed-require`. + * + * SCOPE. Sibling repos are the `xchain-*` directories beside this checkout + * (`--siblings ` overrides the search root), listed in `siblingRepos`. That + * default scope is everything this repo publishes and everything a pin carries. + * + * The surrounding tree may also hold platform tooling that is not a shipped + * service and still reaches in just as hard: the twin-copier script + * reconcile-twins.sh alone byte-copies about thirty of this repo's src/ files + * outward and no CI job runs it, so a sweep that ignores those directories reads + * safer than the tree is.

A restructure that renames test files has to prove + * it changed nothing about what runs, and a passing count proves nothing: a + * renamed file can drop out of one glob while another file joins it and the + * total holds. A suite that silently stops being collected reads as green + * forever. So the invariant is the SET of full test titles per file, per npm + * script, and a later run is compared against the committed pin through the + * rename map that the moving commit declares. + * + * WHY IT NEEDS NO DATABASE. `mocha --dry-run` loads every spec file and walks + * the suite tree without invoking a single hook or test body. Titles are + * declared at load time, so they are all there; nothing connects, nothing + * writes. That is what makes this pin cheap enough to re-take at every + * milestone instead of once. + * + * EACH SCRIPT RUNS WITH ITS OWN ARGUMENTS, unchanged apart from the reporter + * and the dry run. That matters more than it looks: the plain `test` script + * carries no --no-config, so .mocharc.yml's spec list merges with its + * positional globs, and a run that "tidied" the arguments would pin a + * different collection than the one CI executes. A --grep stays, because the + * filtered set is the script's identity. + * + * THE SHAPE ON DISK. Titles are stored once in `titleSets`, keyed by a hash of + * the list, and each script's `files` map points a test file at the set it + * contributed.

sites across the connector and the database layer, so nothing could say what this service is configured by without reading every file, and two sites reading one name could disagree on its fallback without anyone noticing. The home exports accessors rather than a snapshot, which is the whole of the design: several of these knobs are documented and tested as retunable without rebuilding the object that reads them, and a require-time copy looks identical while silently freezing that. Five reads stay where they are, four because they coerce at the read site and the coerced type is a decision rather than a move, one because it is a bare process.env reference with no name to move. --- src/BlockchainConnector.js | 9 +++-- src/config.js | 80 ++++++++++++++++++++++++++++++++++++++ src/db.js | 7 ++-- 3 files changed, 89 insertions(+), 7 deletions(-) create mode 100644 src/config.js diff --git a/src/BlockchainConnector.js b/src/BlockchainConnector.js index 604be7a..9449963 100644 --- a/src/BlockchainConnector.js +++ b/src/BlockchainConnector.js @@ -19,6 +19,7 @@ ********************************************************************/ const axios = require('axios'); +const config = require('./config'); // Read an integer env var, falling back on anything that is not a clean integer. // `??` only substitutes for null/undefined, so a present-but-empty value (a bare @@ -337,14 +338,14 @@ class BlockchainConnector { // Rotation is round-robin, so a recovered primary is retried again if // the fallback also dies. this.endpoints = [normalizeEndpoint(url, port)] - const fallbacks = (process.env.NODE_URL_FALLBACK ??

The rule modules move into the existing src/protocol/ home; the rest are renames. Forced by the moves, in this commit because they break otherwise: require and path.join references across src and test, a regex in the chain-identity gate test that matched the old require specifier through escaped characters, two path.join segment lists that name a source file by parts, and four comments naming a moved path. Two body requires hoisted in src; the codemod also hoisted 56 in test files, and those were put back: the rule is scoped to src, and a require inside an it() block is frequently the assertion itself. One declared test-title change, and no other: a title naming chainIdentity.js now names chain_identity.js. Same 84 files, same 1622 titles otherwise. Not moved, each for a reason: bufferutils.js and its in-process twin, which the image build copies over a dependency by literal path; the decoder metrics, because the observability directory is vendored and grading stops at its prefix; the connector and the network table, which three sibling repos hold at the same depth and one cross-repo test resolves from a single path template; and the reorg-halt clear, which xchain-node runs by its literal path inside this repo's container, so it keeps its hyphenated name at src/ rather than following the snake_case sweep. --- bin/pins/dead-code-sweep.txt | 2 +- src/XChainBlockDecoder.js | 2 +- src/XChainDecoder.js | 24 +++++++++---------- src/api.js | 6 ++--- ...ilsPatch.js => apply_bufferutils_patch.js} | 0 ...inConnector.js => blockchain_connector.js} | 0 src/clear-reorg-halt.js | 2 +- src/{CryptoNetworks.js => crypto_networks.js} | 0 src/db.js | 6 ++--- src/{decoderMetrics.js => decoder_metrics.js} | 0 .../action_aliases.js} | 2 +- .../batch_sub_command_capture.js} | 6 ++--- .../chain_identity.js} | 0 .../dispenser_cancel_grace.js} | 2 +- .../dispenser_expiry_realign.js} | 2 +- .../fee_destination.js} | 2 +- ...BatchLimits.js => indexer_batch_limits.js} | 0 .../oracle_fee_output.js} | 2 +- test/chaos/CE02-rpcTimeouts.chaos.js | 2 +- test/e2e/helpers/txBuilder.js | 2 +- test/fuzz/invariants.js | 4 ++-- test/integration/helpers/txBuilder.js | 2 +- test/mutation/stryker.config.mjs | 4 ++-- test/mutation/stryker.phase2.config.mjs | 4 ++-- .../connectorSecurity.security.test.js | 2 +- .../errorSanitization.security.test.js | 6 ++--- test/smoke/cryptoNetworks.smoke.js | 2 +- test/smoke/moduleLoading.smoke.js | 6 ++--- test/tools/sync-batch-limits.js | 8 +++---- test/unit/BlockchainConnector.test.js | 2 +- test/unit/CryptoNetworks.test.js | 4 ++-- test/unit/applyBufferutilsPatch.test.js | 2 +- test/unit/auxpowReassembly.test.js | 4 ++-- test/unit/auxpowStripParity.test.js | 6 ++--- test/unit/batchDispenserRegistration.test.js | 2 +- test/unit/batchLimitsVendoring.test.js | 12 +++++----- test/unit/batchSubCommandNameGate.test.js | 4 ++-- ...hSubCommandOutputCaptureActivation.test.js | 2 +- test/unit/batchWholeBatchRejection.test.js | 8 +++---- test/unit/blockchainConnector.extra.test.js | 2 +- .../blockchainConnectorReviewFixes.test.js | 2 +- test/unit/chainGenesisPin.test.js | 4 ++-- test/unit/chainIdentityGate.test.js | 10 ++++---- test/unit/decoderTipStaleSurface.test.js | 2 +- test/unit/dispenserCancelGrace.test.js | 2 +- .../dispenserCancelGraceActivation.test.js | 4 ++-- test/unit/dispenserExpiryRealign.test.js | 2 +- .../dispenserExpiryRealignActivation.test.js | 2 +- test/unit/dispenserFieldOffsets.test.js | 4 ++-- test/unit/dispenserLifecycleMirror.test.js | 2 +- test/unit/dispenserOracleFeeOutput.test.js | 2 +- test/unit/feeDestination.test.js | 2 +- test/unit/nodeReachabilityStatus.test.js | 4 ++-- test/unit/nodeUrlFailover.test.js | 2 +- 54 files changed, 96 insertions(+), 96 deletions(-) rename src/{applyBufferutilsPatch.js => apply_bufferutils_patch.js} (100%) rename src/{BlockchainConnector.js => blockchain_connector.js} (100%) rename src/{CryptoNetworks.js => crypto_networks.js} (100%) rename src/{decoderMetrics.js => decoder_metrics.js} (100%) rename src/{actionAliases.js => protocol/action_aliases.js} (96%) rename src/{batchSubCommandCapture.js => protocol/batch_sub_command_capture.js} (99%) rename src/{chainIdentity.js => protocol/chain_identity.js} (100%) rename src/{dispenserCancelGrace.js => protocol/dispenser_cancel_grace.js} (98%) rename src/{dispenserExpiryRealign.js => protocol/dispenser_expiry_realign.js} (97%) rename src/{feeDestination.js => protocol/fee_destination.js} (98%) rename src/protocol/{indexerBatchLimits.js => indexer_batch_limits.js} (100%) rename src/{oracleFeeOutput.js => protocol/oracle_fee_output.js} (99%) diff --git a/bin/pins/dead-code-sweep.txt b/bin/pins/dead-code-sweep.txt index a6cd33f..b9d1d2e 100644 --- a/bin/pins/dead-code-sweep.txt +++ b/bin/pins/dead-code-sweep.txt @@ -63,7 +63,7 @@ VERDICT: src/bufferutils.js is LIVE.

Every suite is now .test.js in snake_case, a kind infix is dropped where the directory already says it (security, boundary, regression, unit) and becomes a word where it does not (extra, queries), and the fuzz harnesses keep .fuzz.js because the fuzz glob keys on it. The 52 files that are not suites move into a support/ directory inside their own kind: each kind's setup and helpers, the fuzz mutators, the benchmark harness with its mocks and scenarios. The batch-limit generator was never a test at all and moves to bin/ beside the other operator tools. Rewritten in this commit because a rename without them collects zero files and reads green forever: five kind globs, every --require path across 20 npm scripts, the tier manifest the enforcement suite reads, the two docker wrappers, the mutation configs, the workflow, and the benchmark scenario names in both the harness list and the stored baseline. Also three sibling pins that now name the tracker's renamed files: without them the AuxPoW parity and safe-depth suites do not fail, they SKIP, which is nine assertions going quiet. Same 84 unit files through the rename map, same titles, no suite added or lost. --- .github/workflows/ci.yml | 2 +- bin/coverage-thresholds.json | 2 +- bin/run-e2e.sh | 2 +- bin/run-integration.sh | 2

Sep 17 00:00:00 2001 From: J-Dog Date: Sun, 13 Sep 2026 15:47:26 -0700 Subject: [PATCH 012/156] refactor: one logger, one export shape, and requires at the top The 150 raw console calls outside the three process entry points now go through the shared logger. A call with one argument passes it straight through; a call with two or more is folded through node's formatter under a name that cannot collide with this repo's own util module, which is what the vendored console patch already does at runtime, so a folded line renders exactly what it rendered before. The two files that exported a class and then attached named helpers to it line by line now attach them in one Object.assign. module.exports IS the class in both, so this is the same assignment written once, and no call site in this repo or any consumer changes. Two requires move out of function bodies: the coin registry, which the startup pin reads, and dotenv, whose CALL stays inside main because the environment must be read at run time. One source-text assertion and one halt-diagnostics assertion follow: the halt line now reaches the logger the suite already installs rather than console.error, so the test reads the sink. Driven: with the message text changed, that assertion goes red, and back to green when it is restored. --- src/XChainDecoder.js | 225 +++++++++++---------- src/blockchain_connector.js | 52 +++-- src/clear-reorg-halt.js | 8 +- src/db.js | 124 ++++++------ src/protocol/fee_destination.js | 4 +- src/util.js | 7 +- test/unit/chain_genesis_pin.test.js | 2 +- test/unit/decoder_halt_diagnostics.test.js | 38 ++-- 8 files changed, 245 insertions(+), 215 deletions(-) diff --git a/src/XChainDecoder.js b/src/XChainDecoder.js index 4adecc3..c118faa 100644 --- a/src/XChainDecoder.js +++ b/src/XChainDecoder.js @@ -19,6 +19,7 @@ ********************************************************************/ const util = require('./util') +const coins = require('./coins') const crypto = require('crypto'); const bs58check = require('bs58check') const bitcoin = require('bitcoinjs-lib') @@ -38,6 +39,8 @@ const { chainTierMismatch, chainFieldMissing, chainGenesisMismatch, chainGenesis // the whole content of the event. getLogger() resolves lazily, so requiring it // here is safe before patchConsole()/installObservability() has run. const { getLogger } = require('./observability') +const { format: formatLogLine } = require('node:util'); +const logger = getLogger(); const strictTextDecoder = new TextDecoder('utf-8', { fatal: true }) const lenientTextDecoder = new TextDecoder('utf-8') @@ -311,12 +314,12 @@ class XChainDecoder { // Coin/network-prefixed loggers so cadence/reorg/stall lines are self-describing // even when a log pipeline strips container labels.

The documentation layer is a product requirement here: the owner wrote these comments so a reader who does not program can follow a file top to bottom, and a suite cannot notice their absence because a comment cannot fail a test. 260 comment runs come back, each anchored to the line of code it was written about rather than to a line number, so a run lands above its own statement wherever the restructure moved it. Not a revert: the same sweep also rewrote surviving lines while scrubbing internal references, and reverting a file would duplicate the rewritten text and put back a reference the push gate refuses. Comment-only, and proven so rather than asserted: with comments and blank lines stripped, all 34 files are byte-identical to their committed versions. --- test/benchmarks/support/harness.js | 36 +++++++++++++++++ .../scenarios/block_processing.bench.js | 5 +++ .../support/scenarios/deobfuscation.bench.js | 3 ++ .../support/scenarios/large_payload.bench.js | 2 + .../support/scenarios/mempool_stress.bench.js | 4 ++ .../scenarios/parse_transaction.bench.js | 3 ++ .../support/scenarios/spike_load.bench.js | 5 +++ .../support/scenarios/sustained_sync.bench.js | 3 ++ test/e2e/action_decoding.test.js | 14 +++++++ test/e2e/error_handling.test.js | 20 ++++++++++ test/e2e/indexer_contract.test.js | 16 ++++++++ test/e2e/multi_block_processing.test.js | 39 +++++++++++++++++++ test/helpers/node_helper.js | 4 ++ test/integration/dispensers.test.js | 22 +++++++++++ test/integration/malformed.test.js | 19 +++++++++ test/integration/op_return.test.js | 19 +++++++++ test/security/action_validation.test.js | 2 + test/smoke/database_init.test.js | 3 ++ test/smoke/parse_multisig.test.js | 16 +++----- test/smoke/parse_op_return.test.js | 14 +++---- test/unit/alias_expansion_boundary.test.js | 23 +++++++++++ test/unit/blockchain_connector.test.js | 7 ++++ test/unit/blockchain_connector_extra.test.js | 18 +++++++++ test/unit/boundary/deobfuscation.test.js | 12 ++++++ test/unit/boundary/dispenser_parsing.test.js | 32 +++++++++++++++ test/unit/boundary/satoshi_conversion.test.js | 8 ++++ test/unit/boundary/script_types.test.js | 24 ++++++++++++ test/unit/db.test.js | 25 ++++++++++++ test/unit/litecoin_block.test.js | 18 +++++++++ test/unit/roundtrip.test.js | 19 +++++---- test/unit/xchain_block_decoder.test.js | 12 ++++-- test/unit/xchain_decoder.test.js | 24 ++++++++++++ 32 files changed, 443 insertions(+), 28 deletions(-) diff --git a/test/benchmarks/support/harness.js b/test/benchmarks/support/harness.js index 71c6762..ed20edd 100644 --- a/test/benchmarks/support/harness.js +++ b/test/benchmarks/support/harness.js @@ -25,6 +25,31 @@ * node test/benchmarks/support/harness.js --quick # reduced iterations */ +/********************************************************************* +* +* Copyright © 2025–2026 Dankest, LLC +* Based on XChain Platform by Dankest, LLC – https://dankest.llc +* +* SPDX-License-Identifier: AGPL-3.0-or-later +* +* This file is part of XChain Platform.

The three modules that talk to or parse a coin node (the RPC connector, the network-parameter table and the block decoder) become src/chain/, which is the feature they share. The reorg-halt clear stays at src/clear-reorg-halt.js despite being an operator command rather than service code: xchain-node execs it inside the decoder container by that literal path, and the Dockerfile copies only ./src, so joining the other one-off tools in bin/ would leave the container image without it and break every `xchain-node clear-reorg-halt` call. Two sibling pins move with them, and both were failing OPEN rather than loud: the encoder parity suites resolve that repo's validator, which moved into a directory of its own there, so six assertions had gone quiet as skips. Top-level source files fall from 14 to 11. What stays is named with a reason: the api, the main class, the database and the config home are the declared layout; util.js is the style doc's own top-level example; the migrator is an entry point the shared lint preset pins by that path; the reorg-halt clear is named by path from outside this repo; the metrics module cannot join the vendored observability tree, which is excluded from grading by prefix and would hide it; and the bufferutils pair is copied over a dependency by a literal path in the image build, which this change does not touch. --- src/XChainDecoder.js | 6 +++--- src/{ =>

It deleted comment runs, which a restore pass puts back and a coverage floor proves. It also REWROTE runs it kept, scrubbing internal references, and some of those rewrites took the explanation along with the reference: the file ends up with a comment in the same place, shorter, saying less, and nothing notices. bin/comment-run-pairs.js finds those. It pairs each before-and-after comment run by token overlap, at a floor of 0.3, rather than by line, because rewrapping a paragraph changes every line in it and line pairing reports a pure rewrap as a total loss. 1370 runs paired across this repo's sweep, 134 lost words, and reading every one of those shows the large majority are the scrub working: the reference went and the sentence around it stayed, often tighter than before. Two in the main class were real losses and are merged back without the reference: the worked example showing an 8192-byte payload stored as 8197 bytes after alias expansion, and the field-by-field account of what the canonicalizer returns. The main class is also the file a human reads first for this service, so the validation checks in it now each carry a plain-language line: the whole envelope-grammar walk, the stall gates, the size cap, the unknown-action rule, the one-carrier rule and the source-attribution rule. Comment-only, proven by stripping comments and blank lines and comparing bytes. --- bin/comment-run-pairs.js | 177 +++++++++++++++++++++++++++++++++++++++ src/XChainDecoder.js | 70 ++++++++++++++-- 2 files changed, 241 insertions(+), 6 deletions(-) create mode 100644 bin/comment-run-pairs.js diff --git a/bin/comment-run-pairs.js b/bin/comment-run-pairs.js new file mode 100644 index 0000000..4ee22c1 --- /dev/null +++ b/bin/comment-run-pairs.js @@ -0,0 +1,177 @@ +#!/usr/bin/env node +/********************************************************************* + * + * Copyright © 2025-2026 Dankest, LLC + * Based on XChain Platform by Dankest, LLC - https://dankest.llc + * + * SPDX-License-Identifier: AGPL-3.0-or-later + * + * This file is part of XChain Platform.

The indexer applies -// the 250 cap, the dotted-TICK ISSUE exemption and the DEPLOY cap only at/after -// BATCH_ISSUANCE_LIMITS. This module applies the POST-flag rule set UNCONDITIONALLY, and -// that is sound rather than convenient, for two separate reasons: -// -// 1. Nothing here can run below BATCH_SUBCOMMAND_OUTPUT_CAPTURE_ACTIVATION, and that gate -// is REQUIRED to sit at or after the indexer's BATCH_ISSUANCE_LIMITS instant on every -// armed network - the LEDGER tier of batchSubCommandOutputCaptureActivation.test.js, -// which predates this change and exists for the settlement ledger. So at every block -// time these rules are evaluated, that flag is already on. batch_limits_vendoring.test.js -// completes the argument by pinning the other two halves of the indexer's own gate -// (its block-index thresholds are 0, and its registered semver is at or below the -// indexer's compiled CONSENSUS_VERSION), so "the time has passed" really does mean -// "the flag is active" and not merely "one of its three conditions is met". -// 2. Even if that ordering were somehow violated, the two UNGATED mirrors stay correct and -// the two rules the SUB-SET direction protects still cannot suppress a dispatched -// batch: below the flag the indexer's ISSUE cap is STRICTER (every dotted child counts -// top-level) and its MINT cap is STRICTER (raw occurrences, not distinct ticks), so a -// mirror written to the post-flag rule refuses a SUBSET of what it rejects. Only the -// 250-command cap and the DEPLOY cap genuinely need reason 1, and they are named here -// rather than buried so the day the ordering changes, this comment is the thing to -// re-read. -// -// THE TRAP THIS ROW EXISTS FOR: after BATCH_ISSUANCE_LIMITS arms, a batch of ONE parent plus -// MANY dotted children is VALID. A decoder that naively mirrored the pre-flag `ISSUE: 1` cap -// would suppress capture for exactly those batches - UNDER-capture, on the very feature the -// flag ships.

Same fault class +// the DISPENSER-prefix tightening closed, reached through a SIBLING command. +// +// Only the EMPTY name is acted on, because suppression is the UNDER-capture direction: +// refusing capture for a batch the indexer really runs loses a real settlement output. +// The decoder holds no copy of the indexer's name registry, and 53 names enabled there +// are absent from VALID_ACTION_NAMES here, so a gate keyed on the decoder's own known +// set would suppress capture for batches that dispatch normally.

Both headers state their own contract. - - // Mirror a DISPENSER format-2 edit that re-dates EXPIRATION, so the block-time - // soft-expire (deleteOpenDispensers) does not close a decoder row while the indexer - // still considers the dispenser live. Two deliberate departures from a faithful - // mirror, both of which make a wrong resolution benign instead of money-bearing: - // - // 1. EXTEND ONLY. GREATEST(expiration, ?) never brings an expiration forward, so - // an edit that SHORTENS the expiry is not mirrored at all: the indexer closes at - // the edited time and the decoder keeps capturing a little longer. Mirroring the - // shortening faithfully would mean closing early on a guessed row. - // 2. NO TARGET SELECTION. Every open row of that source is extended, not one - // chosen by an ORDER BY. The correct row is therefore ALWAYS extended (which a - // LIMIT 1 guess could miss - itself an early close), and any other row of the - // same source is merely held open longer, which the indexer absorbs. - // - // Matching address_id OR source_address_id keeps the delegated case working: - // address_id is the operating address (GET_ADDRESS when delegated), source_address_id - // the create SOURCE, stored only when the two differ, so an edit issued by the - // creator of a delegated dispenser still reaches its row. - // - // THIS-BLOCK RESTORE. BELOW DISPENSER_EXPIRY_REALIGN_ACTIVATION deleteOpenDispensers - // runs at block START, before the - // transaction loop, while the indexer expires at block END, after it. So on the block - // whose header time first passes an expiration, this mirror is handed a row that the - // block-start soft-expire has ALREADY stamped, and an `expired_block_index IS NULL` - // filter cannot reach it: the extend silently does nothing, the row stays closed - // forever, and the decoder stops capturing payments to a dispenser the indexer applies - // the same edit to and keeps OPEN. That is the money-bearing direction, and it is the - // exact failure the paragraph above says this mirror exists to prevent, so the filter - // now admits a row expired by THIS block and clears the mark on it. - // - // Scoped to `expired_block_index = blockIndex` only. A row expired in an EARLIER block - // stays closed: reopening one would be exactly the mirror-on-a-guessed-row the advisory - // note above rules out, and the indexer has long since settled that dispenser's - // lifecycle. - // Same shape as deleteBlockByIndex's reorg clear, which also keys the reset on the - // stamping height, so a re-processed block remains idempotent. - // - // AT/ABOVE that gate the soft-expire moves to the end of the block loop, so no row - // carries a stamp from THIS block while the loop is running and the widened filter is - // simply never exercised on a fresh pass. It still matters on a RE-PROCESSED block - // (the stamp from the earlier pass survives), and it is what keeps the two eras' write - // behavior identical on every input the legacy era could produce, so this clause stays. - // - // The caller has already validated newExpiration is present, in range and future. - // A stale/unknown SOURCE matches zero rows and is a no-op.

The start-failure and process crash records move to src/api/crash_reporting.js, the health method's DB and halt probes to src/api/health_probe.js, and the metrics and log shim wiring to src/api/observability_wiring.js, byte for byte. The entry keeps the health and /status payloads, getmempool and the middleware in named functions under the length limit, reading the running flag and start error through getters. Two source scans follow the moved text into its part, and three comments that pointed at moved text now name its new home. --- src/api.js | 450 ++++++++------------ src/api/crash_reporting.js | 93 ++++ src/api/health_probe.js | 55 +++ src/api/observability_wiring.js | 48 +++ test/chaos/ce08_signal_handling.test.js | 2 + test/unit/decoder_tip_stale_surface.test.js | 2 +- 6 files changed, 380 insertions(+), 270 deletions(-) create mode 100644 src/api/crash_reporting.js create mode 100644 src/api/health_probe.js create mode 100644 src/api/observability_wiring.js diff --git a/src/api.js b/src/api.js index 89c7020..b46a74f 100644 --- a/src/api.js +++ b/src/api.js @@ -42,8 +42,6 @@ const { createShutdown, createDecoderDrain } = require('./shutdown'); const XChainDecoder = require('./XChainDecoder'); const { resolveFeeDestination } = require('./protocol/fee_destination'); const jsonRouter = require('express-json-rpc-router') -const { installObservability, getLogger } = require('./observability'); // default-off /metrics + structured log shim -const { registerDecoderMetrics } = require('./decoder_metrics'); // decoder feed-freshness gauges const { makeRpcBatchGuard, registerLiveRoute, @@ -53,6 +51,9 @@ const { ageProbeLogState, PROBE_LOG_WINDOW_MS } = require('./api/probe_routes'); +const { reportStartFailure, installCrashHandlers } = require('./api/crash_reporting'); +const { getHealthProbeState } = require('./api/health_probe'); +const { installDecoderObservability } = require('./api/observability_wiring'); const NETWORK = process.env.NETWORK const NODE_URL = process.env.NODE_URL @@ -72,149 +73,115 @@ const AUX_POW = process.env.AUX_POW === 'true' || process.env.AUX_POW === '1' const FEE_DESTINATION = resolveFeeDestination(NETWORK, process.env.FEE_DESTINATION || null) -async function startApi(){ - // Validate required env vars that have no safe default: a missing port causes Node to - // bind a random OS-assigned port, making the container appear healthy while every - // downstream caller gets connection-refused.

The loop-carried cursors, counters and latches live on one object the steps share. A step that ended the iteration returns 'continue', and one that rolled the block back returns 'rollback', so the loop runs resetAfterRollback after every write the step made, as before. Each step that awaits suspends on the same node or database wait the loop did before it can return, and every other step stays synchronous. The consensus pin check stays the first statement of start, so its refusal is still thrown before anything is awaited. The source-reading tests follow the code into the parts. The chain-identity require check accepts the parts' ../ path. --- src/XChainDecoder.js | 1440 +------------------ src/XChainDecoder/block_ingest.js | 388 +++++ src/XChainDecoder/dispenser_registration.js | 385 +++++ src/XChainDecoder/startup.js | 309 ++++ src/XChainDecoder/sync_loop.js | 117 ++ src/XChainDecoder/tip_refresh.js | 262 ++++ src/XChainDecoder/transaction_ingest.js | 311 ++++ test/chaos/ce10_fire_and_forget.test.js | 2 +- test/security/dispenser_validation.test.js | 4 +- test/unit/chain_genesis_pin.test.js | 5 +- test/unit/chain_identity_gate.test.js | 2 +- test/unit/decoder_tip_stale_surface.test.js | 2 +- test/unit/node_catch_up_wait.test.js | 2 +- test/unit/node_catching_up_status.test.js | 2 +- 14 files changed, 1786 insertions(+), 1445 deletions(-) create mode 100644 src/XChainDecoder/block_ingest.js create mode 100644 src/XChainDecoder/dispenser_registration.js create mode 100644 src/XChainDecoder/startup.js create mode 100644 src/XChainDecoder/sync_loop.js create mode 100644 src/XChainDecoder/tip_refresh.js create mode 100644 src/XChainDecoder/transaction_ingest.js diff --git a/src/XChainDecoder.js b/src/XChainDecoder.js index 8e34884..6710076 100644 --- a/src/XChainDecoder.js +++ b/src/XChainDecoder.js @@ -18,23 +18,15 @@ * ********************************************************************/ -const util = require('./util') -const coins = require('./coins') const bs58check = require('bs58check') const bitcoin = require('bitcoinjs-lib') const { createHash } = require('crypto') -const Database = require('./db.js') const ecc = require('tiny-secp256k1') const BlockchainConnector = require('./chain/blockchain_connector') const CryptoNetworks = require('./chain/crypto_networks') const XChainBlockDecoder = require('./chain/XChainBlockDecoder') -const { oracleAddressFromCreate, V0_GIVE_COIN_INDEX, V0_GET_COIN_INDEX, V0_GET_ADDRESS_INDEX, V0_EXPIRATION_INDEX, V2_EXPIRATION_INDEX } = require('./protocol/oracle_fee_output') -const { isDispenserExpiryRealignActive } = require('./protocol/dispenser_expiry_realign') -const { cancelGraceFloor } = require('./protocol/dispenser_cancel_grace') -const { captureCommands, collapseDispenserRegistrations, isBatchSubCommandCaptureActive } = require('./protocol/batch_sub_command_capture') -const { chainTierMismatch, chainFieldMissing, chainGenesisUnpinned } = require('./protocol/chain_identity') const { format: formatLogLine } = require('node:util'); -const { logger, CHECK_BLOCK_DELAY_MS, BLOCKCHAIN_INFO_REFRESH_MS, MEMPOOL_INTERVAL, REORG_HALT_PARK_TICK_MS, FUNDING_VOUT_BASE, SYNCED_THRESHOLD, DISPENSER_EXPIRE_SAFE_DEPTH, MIN_VERIFICATION_PROGRESS_TO_PARSE, VALID_ACTION_NAMES, DB_TRANSACTION_BLOCKS_QUANTITY, LOG_BLOCK_INTERVAL, TX_PARSE_MAX_RETRIES, AUXPOW_REASSEMBLE_AFTER } = require('./XChainDecoder/constants.js') +const { logger, FUNDING_VOUT_BASE, DISPENSER_EXPIRE_SAFE_DEPTH, VALID_ACTION_NAMES, AUXPOW_REASSEMBLE_AFTER } = require('./XChainDecoder/constants.js') const { nodeStillCatchingUp, compiledPushSize, canonicalizeActionPayload, bigIntBufferutilsActive } = require('./XChainDecoder/payload_helpers.js') const syncStatusMethods = require('./XChainDecoder/sync_status.js') const chainIntegrityMethods = require('./XChainDecoder/chain_integrity.js') @@ -43,6 +35,7 @@ const envelopeRecognitionMethods = require('./XChainDecoder/envelope_recognition const dispenserAndOracleFeeMethods = require('./XChainDecoder/dispenser_and_oracle_fees.js') const transactionParsingMethods = require('./XChainDecoder/transaction_parsing.js') const reorgVerificationMethods = require('./XChainDecoder/reorg_verification.js') +const startupMethods = require('./XChainDecoder/startup.js') const mempoolRefreshMethods = require('./XChainDecoder/mempool_refresh.js') //We need to init the ecc to parse taproot addresses from output scripts @@ -288,1434 +281,6 @@ class XChainDecoder { initializeDecoderReorg(this) initializeDecoderHaltState(this) } - - async start(){ - // Verify the bundled canonical coin files against CONSENSUS_CONFIG_PIN - // before touching the DB or processing any block, mirroring the indexer. - // A null pin (mainnet, pre-arm) skips; a mismatch on an armed network - // throws and halts startup, so a partial/stale deploy cannot parse - // on-chain bytes with divergent network params (fail-closed, deliberately - // not wrapped in try/catch). - coins.verifyConsensusPin(this.consensusNetwork) - - // Refuse an endpoint that is provably a DIFFERENT CHAIN before the DB is touched - // or a single block is read.

These rows are keyed on - // (tx_index, operating address) and nothing here is keyed on an - // action index, so nothing is approximated by not having one. - // - // THE PREFIX CARRIES ITS DELIMITER at/above the same gate, and only - // there. `startsWith("DISPENSER")` selects on a bare action NAME, but - // the wire delimits the name with '|', so it also matches every - // longer string sharing that head: `DISPENSERX|0|...`, which - // xchain-indexer/src/actions/index.js dispatches nowhere, and the real but - // indexer-SYNTHESIZED DISPENSER_CLOSE / DISPENSER_EXPIRE (both sit in - // FEE_QUOTE_EXEMPT beside DISPENSE and ORDER_MATCH), whose - // wire-spelled form carries no resolvable DISPENSER_ACTION_INDEX and - // so resolves no dispenser there either. The indexer runs NOTHING for - // any of them while the bare prefix has the decoder splitting on '|', - // reading field [1] as a DISPENSER FORMAT, and registering a create - // (or extending an open row on a format-2 read). The registry IS the - // set that decides which outputs become DISPENSE outputs, so the - // decoder then captures dispenses no indexer will ever settle. The - // direction is over-capture, which is why it was survivable and why - // it closes on a flag-day rather than as a hotfix. - // - // WHERE IT IS ACTUALLY REACHABLE, which is not where it looks.

Money-bearing, and a +// live decoder/indexer divergence. +// +// TWO PASSES, both in sub-command position order: +// 1. every v0 create is validated, the set is collapsed to one +// registration per OPERATING ADDRESS (see +// collapseDispenserRegistrations: the dispensers PRIMARY KEY is +// (tx_index, address_id), which a batch can collide with), and +// the survivors are inserted; +// 2. the format-1/2 lifecycle mirrors run AFTERWARDS, so an edit +// anywhere in the batch reaches a dispenser created anywhere in +// the same batch. The indexer dispatches in strict position +// order, so an edit placed BEFORE its create fails there while +// the decoder extends a row: that is the hold-open-longer +// direction its advisory contract permits. The reverse ordering +// would let an edit AFTER its create miss the row, which closes +// early - the money-bearing direction. +// +// Per sub-command, not per transaction: EXPIRATION is read from THIS +// command's field [14] (defaulting from the shared block time, as the +// indexer's own default does), and the operating address from THIS +// command's GET_ADDRESS. There is no per-sub-command DISPENSER_ACTION_INDEX +// to reproduce: the indexer mints one per sub-command from its own +// action_index sequence (actions/batch.js -> db.createActionIndex -> +// getNextActionIndex), an id space the decoder has never held for +// top-level dispensers either. These rows are keyed on +// (tx_index, operating address) and nothing here is keyed on an +// action index, so nothing is approximated by not having one. +// +// THE PREFIX CARRIES ITS DELIMITER at/above the same gate, and only +// there. `startsWith("DISPENSER")` selects on a bare action NAME, but +// the wire delimits the name with '|', so it also matches every +// longer string sharing that head: `DISPENSERX|0|...`, which +// xchain-indexer/src/actions/index.js dispatches nowhere, and the real but +// indexer-SYNTHESIZED DISPENSER_CLOSE / DISPENSER_EXPIRE (both sit in +// FEE_QUOTE_EXEMPT beside DISPENSE and ORDER_MATCH), whose +// wire-spelled form carries no resolvable DISPENSER_ACTION_INDEX and +// so resolves no dispenser there either. The indexer runs NOTHING for +// any of them while the bare prefix has the decoder splitting on '|', +// reading field [1] as a DISPENSER FORMAT, and registering a create +// (or extending an open row on a format-2 read). The registry IS the +// set that decides which outputs become DISPENSE outputs, so the +// decoder then captures dispenses no indexer will ever settle. The +// direction is over-capture, which is why it was survivable and why +// it closes on a flag-day rather than as a hotfix. +// +// WHERE IT IS ACTUALLY REACHABLE, which is not where it looks. NOT at +// the top level: buildStoredActionRecord runs the VALID_ACTION_NAMES +// gate first, and that set holds 'DISPENSER' and no other name +// beginning DISPENSER, so `DISPENSERX|...` is blanked to '' before +// this walk ever sees it. The one top-level string that survives that +// gate and still misses `DISPENSER|` is the bare token 'DISPENSER' +// with no pipe at all, whose field [1] is undefined and whose FORMAT +// therefore parses NaN, matching no branch below either way. +// Sub-commands get NO such gate: the name checked was BATCH, and +// nothing re-checks the pieces. Row 26's walk is what made this +// reachable, and `BATCH|0|DISPENSERX|0|...` really does register. +// +// WHY IT IS GATED ANYWAY, given that the below-gate branch is a +// provable no-op today. That proof rests entirely on the membership +// of VALID_ACTION_NAMES, a set that can gain a DISPENSER-prefixed +// name later; the day it does, a from-genesis re-decode of history +// BELOW the flag-day must still reproduce the over-captured rows the +// fleet wrote, and only a gate can promise that in advance.
