2 high7 low1 info
1.highEscrow takes an event with no block_number key as clean evidence: a malformed open/release/refund yields funded/claimed/refunded, and gets past the finalized-height boundobservatory/src/escrow.ts:105
if (n !== null && n !== undefined && !isSafeInt(n)) {2.highRollback check reads only the last log line: one snapshot with no RPC reading in between hides a finalized-height rollback, and RPC health reads okobservatory/src/cli.ts:156
const st = readSnapshots(log).at(-1)?.status;
RULES.md 1.1 says: when there is a previous snapshot on the same genesis, there must be no rollback, no changed finalized hash and no stuck height. cli.ts takes only readSnapshots(log).at(-1). If that snapshot has no RPC genesis or finalized head (the RPC was not read or the read failed), previous stays null and all three checks are skipped.
The next snapshot's RPC health is then ok even though its finalized height is below the one recorded two lines earlier on the same genesis. So fix 4 (finding 4 of a24f9aa1) is only partly done.
Impact: WRONG HEALTH (ok after a rollback, conflicts empty). Reproduced by running.
Fix: walk the verified log back to the latest snapshot whose status has an RPC genesis equal to the current one and a finalized head, or carry the highest finalized head seen per genesis.
3.A finalized height stuck across many snapshots is never reported: the stuck time is measured only since the immediately previous snapshotobservatory/src/status.ts:174
const since = secondsBetween(previous.observed_at, o.now);
RULES.md 1.1 says there must be no finalized height stuck for longer than the stale limit (120 s), and rpc.stale is true when the height is stuck. classifyRpc measures the stuck time as now minus the previous snapshot's observed_at. With snapshots taken more often than the limit, the height can stay at one value forever and every snapshot sees only 60 s.
Impact: WRONG HEALTH and stale value (ok/false while the height has not moved for 4+ minutes). interfaces/README tells Seat Court to use rpc.stale for deadlines. Reproduced by running.
Fix: carry forward the time a finalized head was first seen (walk back through consecutive snapshots with the same height and hash, or store finalized_since in the status).
4.RPC genesis counts toward reset_detected=false even when the RPC read failed, is days old, or is later than the snapshot (no gate like the faucet /chain one)observatory/src/status.ts:243
const rpcGenesis = normalizeHash(head.genesis_hash);
5.A page file whose name holds a non-UTF-8 byte is silently dropped: escrow reads funded over a finalized release, the TypeScript census shows a gap, Python counts the page as completeobservatory/src/source.ts:111
if (!existsSync(path)) return undefined;
readdirSync decodes an invalid UTF-8 file name to U+FFFD. The entry passes the clause 15 checks, but join(dir, name) names a path that does not exist, so read() returns undefined at
!existsSync(path)and adds nothing to loadErrors or pageErrors. RULES.md section 2 and clause 12 say a page that cannot be read leaves every escrow unverified and refuses the census.Instead the escrow is judged without the page. tools/recount.py lists the directory with os.listdir (surrogateescape), reads the page and calls the census complete.
Impact: WRONG ESCROW STATE (funded although the input holds a finalized release) and a TypeScript/Python disagreement on completeness and totals. Reproduced by running.
Fix: list with encoding 'buffer' and a strict decode, or treat a missing file for a listed entry as a page error. Never return undefined silently for an entry the listing produced.
6.Escrow ignores page chains: an open on a page whose next_page is not in the input reads funded, while the census calls the same chain brokenobservatory/src/escrow.ts:225
for (const page of pageList) { if (pageProblem(page) !== null) continue;Section 2 makes every escrow unverified when a page could not be read, because the missing page could hold a conflicting event. escrowState only checks each page with pageProblem() and never walks page chains. A page that names a next_page missing from the input is not treated as missing, so an open on page 0 with next_page 1 absent gives funded, though page 1 could hold the release or refund. The census over the same input reports a broken chain and a 100-block gap.
The rule names only unreadable and invalid pages, so this is a spec gap too, but its stated reason applies.
Impact: WRONG ESCROW STATE (funded while the evidence that could contradict it is known to be missing). Reproduced by running.
Fix: apply census clause 2 to escrow pages (a broken chain on the pinned genesis, or disagreeing copies of a page number, makes every escrow unverified with a note), and state it in RULES.md 2.
7.Page check lets free text show a wrong value: a th-only 'reset detected / false' row, a p note, a second h1 or a lone th all pass consistency.mjsobservatory/scripts/consistency.mjs:181
if (tds.length === 0) continue; // a header row
8.lowconsistency.mjs allows aria-label with any value on any element, so a cell can read 'false' to a screen reader while its text and data-v say trueobservatory/scripts/consistency.mjs:360
const ATTRS = new Set(["lang", "charset", "name", "content", "class", "scope", "aria-label", "data-k", "data-v", "data-n", "data-for", "data-row", "data-section", "data-col", "data-escrow"]);
The renderer writes aria-label only as aria-label="unknown" on blank unknown cells. The checker allows the attribute name on every element and never compares its value, and aria-label replaces the cell text for assistive technology. Merged from audit_math, audit_permissions and audit_economics.
Impact: a wrong value presented to screen-reader users; the check passes. Reproduced by running.
Fix: accept aria-label only equal to 'unknown', only on a td whose data-v is unknown and whose text is empty.
Copy outputs/reset from the check run and change '' to ''.
node scripts/consistency.mjs <dir>-> exit 0, 2101 checks, failures []. Expected: an attribute failure.9.lowstatus.ts reads heights and the runtime version with Number.isInteger, not the shared isSafeInt: finalized 2^53+1 is reported as 2^53 with rpc health okobservatory/src/status.ts:40
function nonNegativeInt(value: unknown): number | null { return typeof value === "number" && Number.isInteger(value) && value >= 0 ? value : null; }Round 5 says src/strict.ts holds the one safe-integer reading for escrow, census and status. status.ts nonNegativeInt still uses Number.isInteger, so a head whose finalized number JSON.parse has rounded is accepted as present and valid. Its lag is computed from rounded values, and the height becomes the escrow evidence bound. Merged from audit_math and audit_permissions.
Impact: wrong health (ok on an untrusted reading). Unrealistic heights, hence low. Reproduced by running.
Fix: use isSafeInt in nonNegativeInt.
Copy fixtures/status-healthy, set rpc-head.json finalized.number 9007199254740993 and best_number 9007199254740995 (JSON number literals).
node dist/cli.js status --fixtures <dir>-> rpc.health ok, stale false, finalized_height 9007199254740992, best_height 9007199254740996, finality_lag 4, conflicts []. Expected: rpc degraded ('no valid finalized head', 'no valid best height'), finalized_height null.10.lowWhen the previous snapshot's RPC reading time does not parse, the stuck-height check silently does not run and RPC health is okobservatory/src/status.ts:175
if (since !== null && since > o.staleAfterSeconds) {RULES.md 1.1: ok needs every check to run and pass. cli.ts passes the previous snapshot's rpc.observed_at whenever it is non-null, and the status stores the raw head time even when it does not parse (here a zoneless time, which already made that snapshot unknown). In the next snapshot with the same finalized head, secondsBetween returns null and the stuck branch is skipped without marking the check as unable to run.
Impact: wrong health (ok while the height may have been stuck for 70 minutes). Reproduced by running.
Fix: when previous is on the same genesis with the same head and its time does not parse, health unknown, or only take a previous whose observed_at parses.
11.lowA finalized release (or refund) with an unparsable escrow id does not block claimed (or refunded), though a second well-formed release of the same kind makes the escrow unverifiedobservatory/src/escrow.ts:383
if (suspectTerminals.has(REFUNDED)) {Section 2: an unparsable finalized terminal on the pinned genesis could contradict any escrow, and more than one distinct finalized release is a conflict (line 376). The claimed branch checks suspectTerminals only for REFUNDED, and the refunded branch only for RELEASED. So one clean release plus one unparsable finalized release gives claimed, while one clean release plus a second clean release gives unverified.
More conflicting evidence gives a more confident answer.
Impact: WRONG ESCROW STATE (claimed/refunded) in a conflicting-evidence case. Reproduced by running.
Fix: in the claimed branch also treat suspectTerminals.has(RELEASED) as a conflict (REFUNDED in the refunded branch), or state the exception in RULES.md.
/tmp/rp/e4: one page 100..199 with finalized EscrowOpened@110 (0x01..01) and EscrowReleased@120 (0x02..02) for 0xa1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a1, plus a finalized EscrowReleased@130 (0x03..03) with data {'0':'not-an-id'}.

13.lowSource scan misses computed access on process and the Function constructor reached through .constructor, and does not scan src subfoldersobservatory/test/guard.test.ts:170
const files = readdirSync(dir).filter((f) => f.endsWith(".ts") && f !== "guard.ts");RULES.md 4 says the scan fails any src module that uses process.getBuiltinModule, process.binding, eval or Function, and computed access, so that an aliased or computed form cannot slip past. The regexes match only literal spellings, and readdirSync(dir) is not recursive while tsconfig compiles everything under src.
The runtime block in test/setup.ts still catches these if a test runs them, so this is a gap in the static layer, not a live path; no current src file uses these forms. Fix 13 is partly done.
Impact: no current network/sign/spend path. Reproduced by running the scan's own regex list.
Fix: scan recursively and ban
process[,Reflect.get(process,Reflect.and.constructor.constructorin src.14.lowMutation runner fails every control when the temp folder is reached through a symlink, so 206 of 206 cannot be shown there (fails closed)observatory/scripts/mutate.mjs:43
const work = mkdtempSync(join(tmpdir(), "obs-mutate-"));
The work folder comes from os.tmpdir() without realpath. Vitest reports test file names by real path, and relative(copyPkg, f.name) then gives '../../../../realtmp/...', so the control marks every file missing and every mutant 'error'. It fails closed (no false pass), but on stock macOS (/var/folders -> /private/var) the mutants step always exits 1. mutate-canary.mjs and canary.mjs use the same pattern.
Reproduced by running.
Fix: realpathSync(mkdtempSync(...)).

Expected: control-pass and 31 killed, as without the symlink.15.infoMutation runner applies mutants with String.prototype.replace, which expands $& / $' / $` / $$ in the replacementobservatory/scripts/mutate.mjs:160
writeFileSync(target, original.replace(m.find, m.replace));
original.replace(m.find, m.replace) with a string pattern still expands $-patterns in the replacement, so a future mutant containing $& would be written differently from what mutants.json records. No current mutant has such a sequence, so no present result is wrong. Found by reading; the replace behaviour was reproduced.
Fix: original.replace(m.find, () => m.replace) or split/join.
node -e 'console.log("a+b".replace("b","$&$&"))'-> a+bb (not a+$&$&). A mutant {find:'b', replace:'$&$&'} would write 'bb'.

- High –
src/escrow.ts:105. An open or release event with noblock_numberfield gives funded or claimed. Both the TypeScript and Python census count that same event as malformed, and RULES says a malformed event can never set an escrow state. With no block number it also skips the finalized-height check. Wrong escrow state. - Medium –
src/escrow.ts:225. The escrow code never follows page chains. If page 0 holds an open and points to a page 1 that isn't there, the escrow reads funded, while the census over the same pages calls the chain broken. This is partly a gap in the rules too. Wrong escrow state. - High –
src/status.ts:243. The RPC genesis counts towardreset_detectedwhether or not that reading worked. A reading that failed with a timeout and is two days old still gives reset_detected false. The faucet/chainreading has had this check since fix 5; the RPC side doesn't. Wrong reset value. - High –
src/cli.ts:156. The snapshot command reads only the last line of the log. Snapshot A, then one with no RPC reading, then C with a lower finalized height gives RPC health ok and no conflicts. Run A then C directly and it is degraded. Wrong health. - Low –

highSnapshot rollback check reads only the last log line: one snapshot without an RPC reading hides a finalized-height rollback, and RPC health reads okobservatory/src/cli.ts:156
RULES.md 1.1 requires, 'when there is a previous snapshot on the same genesis', no rollback, no changed finalized hash and no stuck height. The CLI takes only the last line of the log. If that snapshot has no RPC genesis or finalized head (the RPC was not read, or the read failed), previous stays null and the three checks are skipped, so the next snapshot's RPC health is ok even when its finalized height is below the one recorded two lines earlier on the same genesis.
A one-off RPC outage between two readings is all it takes.
Impact: wrong health (ok after a rollback), and conflicts stays empty.
Fix: walk the verified log backwards to the latest snapshot whose status has an RPC genesis equal to the current one and a finalized height, hash and rpc.observed_at, and pass that as previous (or keep the highest finalized head seen per genesis).

Medium, escrow and census (area 1 and 3), reproduced by running. A page file whose name holds a byte that is not UTF-8 is silently dropped by the fixture loader. Node decodes the name to U+FFFD, the clause 15 checks pass, and then the path does not exist, so the loader returns undefined without a page error. With a finalized release in such a file, the escrow comes out funded. Python reads the same directory and counts the page, so the two implementations disagree on completeness and totals. File

consistency.mjs allows aria-label on any element with any value, so a cell can read 'false' to a screen reader while its text and data-v say trueobservatory/scripts/consistency.mjs:360
The renderer writes aria-label only as aria-label="unknown" on blank unknown cells (src/page.ts lines 34 and 168). The checker allowlists the attribute name on every element and never compares its value, and an aria-label replaces the cell's text for assistive technology. A tampered page can therefore present reset_detected as false to a screen-reader user while the visible text, data-v and the snapshot all say true, and the check passes.
RULES.md section 5 says only the attributes the renderer writes are allowed; the renderer never writes this attribute with another value or on a cell with a value. Reproduced by running.
Fix: accept aria-label only with the value unknown, only on a td whose data-v is unknown and whose text is empty, and compare it in checkCell.

status.ts accepts unsafe integers for heights and runtime version (Number.isInteger, not the shared isSafeInt): finalized 2^53+1 is reported as 2^53 with rpc okobservatory/src/status.ts:41
The PR says src/strict.ts holds the one reading of a safe integer so that escrow, census and status cannot drift apart, and census clause 14 says a value beyond 2^53-1 is not an integer because JSON parsing has already rounded it. status.ts still reads finalized.number, best_number and runtime_spec_version through nonNegativeInt, which uses Number.isInteger.
A head whose finalized number is 9007199254740993 parses to 9007199254740992 and is reported as a valid finalized height with rpc health ok; the lag is computed from rounded values (4 instead of 2 here). That rounded height is then the finalized height that bounds escrow evidence in buildSnapshot. Found by reading, reproduced by running.
Fix: use isSafeInt from strict.ts in nonNegativeInt so that such a head fails the 'present and valid' check and rpc health is degraded.
When the previous snapshot's RPC reading time does not parse, the stuck-height check silently cannot run and rpc health is still okobservatory/src/status.ts:175
RULES.md 1.1: ok needs every check to run and pass, and a check that cannot run leaves health unknown (as the code does for the head's own observed_at). The stuck check compares previous.observed_at to now; cli.ts passes the previous snapshot's rpc.observed_at whenever it is non-null, and networkStatus stores the raw head observed_at even when it does not parse (a time without a zone, for example, which gives rpc health unknown in that earlier snapshot).
In the next snapshot with the same finalized head, secondsBetween returns null and the stuck branch is skipped without adding to cannotRun, so health is ok although the height may have been stuck for over an hour. Reproduced by running.
Fix: when previous is present on the same genesis with the same finalized head and its observed_at does not parse, push to cannotRun (health unknown) instead of skipping.
A finalized release (or refund) whose escrow id does not parse does not contradict a claimed (or refunded) escrow, although a well-formed second distinct release would make it unverifiedobservatory/src/escrow.ts:383

Findings by area
- Escrow (medium). An escrow event with no
block_numberkey is clean evidence: a lone finalized open comes outfunded. Census and recount call the same event malformed (escrow.ts:105). Wrong escrow state from a malformed event. - Network status (low, two).
nonNegativeIntstill usesNumber.isInteger, so a finalized height of 2^53+1 gives rpc health ok and is handed to the escrows as their bound (status.ts:41). The RPC genesis counts towardreset_detected: falseeven when the head has a read error, is a day old, or is later than the snapshot time, unlike the faucet/chainreading (status.ts:243). The snapshot log path itself works: the rollback case reproduced through the command line. - Census (low). A page with JSON nested 20000 deep: TypeScript counts a complete census,
recount.pydies withRecursionErrorand exit 1 rather than a refusal (recount.py:89). No partial census read as complete and no count including excluded events was found; UTF-8, safe integers, negative ranges and mixed-range copies agree on both sides. - Read only. Nothing at medium or above. Extra probes (
new http.ClientRequest, agentcreateConnection,TLSSocket.connect,cluster.fork,dns.lookupService, CommonJSrequire("http")) are all blocked and recorded. The remaining way to hide an attempt is a test that rewrites the journal with the filesystem, which the harness cannot defend against and I did not file. - Outputs (medium and low).

RULES.md section 2 says a malformed event (missing fields) is ignored and can never make an escrow look funded, claimed or refunded, and clause 7 says an event whose block_number is missing is malformed and that the escrow rules read events the same way. census.ts readEvent (line 235) and recount.py parse_event (line 184) both reject a missing block_number. escrow.ts structureProblem lets undefined through, so a finalized hasStation.EscrowOpened, EscrowReleased or EscrowRefunded with no block_number key is clean evidence: the escrow comes out funded, claimed or refunded, with block_number null in the evidence, and the finalized-height bound can never apply to it.
The TypeScript census and the Python recount call the very same event malformed_dropped 1 with escrows_opened 0, so the two outputs disagree about one event. Wrong escrow state from a malformed event; reproduced by running.
consistency.mjs accepts a fabricated labeled row made of two th cells, and free text in p, h1 or code, so a page can show 'reset detected: false' beside the real 'true' and passobservatory/scripts/consistency.mjs:181
RULES.md section 5 says every value sits where a person reads it and only the intro line and census banner sit outside a section table. The checker only compares elements that carry data-k, requires data-k only on td and span, skips any tr without a td as a header row, and never reads the text of p, h1, th-only rows or code.
So a tampered page can carry a row reset detectedfalse directly above the real reset_detected row (which still says true), or a paragraph 'reset_detected: false' under the Network status heading, or a new h1, and the check reports zero failures. A reader sees two 'reset detected' rows with opposite values. Wrong reset value shown on the page while the check passes; the feeds and MCP stay right.
Reproduced by running on a real reset-scenario snapshot.
consistency.mjs allows any aria-label value, so an assistive reader can be told a different value than the cell showsobservatory/scripts/consistency.mjs:360
The renderer writes aria-label="unknown" only on blank unknown cells, but the checker accepts aria-label with any value on any element and never compares it. A screen reader announces aria-label in place of the cell text, so a tampered true is read aloud as 'false' while the check passes.
Also 'class' is accepted with any value, so a true reset cell can be painted as the grey unknown cell (class="unk") and still pass; the text stays visible, so that one is cosmetic. Found by reading, reproduced by running.
Render the reset scenario as in the previous finding, then in index.html replace 'data-k="status.reset_detected" data-v="true">' with 'data-k="status.reset_detected" data-v="true" aria-label="false">' and run node scripts/consistency.mjs : exit 0, failures [].
Expected: a failure.
Fix: accept aria-label only equal to "unknown" and only on a cell whose data-v is unknown, and restrict class to the values the renderer writes for that key.
Deeply nested JSON in an event page: the TypeScript census counts it complete while recount.py crashes with RecursionError (exit 1, not a refusal)observatory/tools/recount.py:89
RULES.md 3.1 clause 12 requires both implementations to accept standard JSON and to refuse only what is not UTF-8 or not RFC 8259 JSON. Python's json module raises RecursionError on arrays or objects nested a few thousand deep (the C scanner's recursion guard), which is not a ValueError, so load_pages does not turn it into Unreadable: the recount exits 1 with a traceback instead of 2 with a reason, while the TypeScript census parses the same file and prints a complete census.
The two implementations disagree on a valid page, and compare-recount.mjs would report disagree-on-refusal. No count is wrong on the TypeScript side; the Python side gives no answer. Reproduced by running on Python 3.12 (the task's 3.13 has the same guard).
status.ts still uses Number.isInteger for heights and the runtime version, so an unsafe finalized height is accepted as health ok and passed to the escrows as their boundobservatory/src/status.ts:41
Round 5 says src/strict.ts holds the one reading of a safe integer so escrow, census and status cannot drift apart, and RULES.md clause 14 makes any integer beyond 2^53 - 1 untrusted. status.ts nonNegativeInt never uses isSafeInt: an rpc-head.json finalized number of 9007199254740993 (already rounded by JSON.parse to 9007199254740992) and best_number 9007199254740995 give rpc health ok, stale false, finalized_height 9007199254740992 (a value the RPC never reported) and finality_lag 4. buildSnapshot then hands that height to escrowState as finalizedHeight, where every block_number is below it, so the above-the-finalized-height rule can never fire.
The escrow module itself rejects the same numbers in its own fields. Wrong health value (ok on an untrusted reading) and a wrong escrow bound; reproduced by running.
Asymmetry: the RPC genesis counts toward reset_detected false even when the RPC read reports an error, is older than the stale limit or is later than the snapshot time, unlike the faucet /chain readinobservatory/src/status.ts:243
Round 5 fix 5 made the faucet genesis count only from a usable /chain reading (HTTP 200, no error, a reading time that parses, is fresh and not later than the snapshot). The RPC side got no such test: head.genesis_hash is taken whatever head.error, head.observed_at age or a future observed_at says, so reset_detected is false on the word of an RPC reading the status itself calls degraded for a read error, a day-old head, or a head time later than the snapshot.
A stale head read before a reset keeps reset_detected false after it. Callers are told to gate spends on reset_detected === false, and interfaces/README.md only tells Seat Court to also check rpc.stale for deadlines. Wrong reset value in the sense of RULES section 1 (unknown is never good news) and of the task's definition of a usable reading; reproduced by running.

Mutation runner applies mutants with String.prototype.replace, which interprets $-patterns in the replacement text, so a future mutant containing $&, $', $` or $$ would be applied differently from whaobservatory/scripts/mutate.mjs:160
original.replace(find, replace) with a string pattern still treats $&, $`, $', $$ and $n in the replacement as substitution patterns (ECMAScript GetSubstitution). The 'find matches exactly once' check on line 152 does not cover the replacement, and the runner then reports the mutant as applied.
None of the 206 current mutants carries such a sequence (grep of mutants/*.json for $ followed by &, `, ', $ or a digit finds nothing), so no present result is wrong; the mutant written to the copy could differ silently from the one documented, and a 'killed' could be for a different change than the one recorded. Found by reading, not reproduced against a shipped mutant.
Fix: use original.replace(m.find, () => m.replace) or split/join, and add a mutate-canary case whose replacement contains $&.
node -e "console.log('a+b'.replace('b', '$&$&'))" prints a+bb, not a+$&$&.
A mutants/*.json entry with "find":"b","replace":"$&$&" on a file holding one b would therefore write bb into the copy while mutants.json records the replacement text $&$&.

/chainreading now gives reset_detected null, and a release above height 150 is unverified. For 8 and 9 the evidence is the check run's canary and mutation results. I did not open the drift-long-decimal fixture for 10; its test passed in the run. - Partly fixed (3):
- Fix 4: the previous snapshot is now read only from the log's last line, so one snapshot without an RPC reading hides a rollback.

- Not fixed: none.
New findings
High
- Missing block_number counts as evidence (
src/escrow.ts:105): an event with noblock_numberkey is taken as clean evidence, giving funded, claimed or refunded. With a finalized height of 150 such a release still gives claimed with no notes, because a null block number skips the height bound. Both censuses call the same event malformed. Wrong escrow state. - Rollback hidden (
src/cli.ts:156): if the last snapshot has no RPC reading, a rollback in the next one reads ok with no conflicts. Wrong health.
Medium
- Stuck height never caught (
src/status.ts:174): the stuck time is measured only since the last snapshot. Five snapshots 60 s apart on an unchanged height all read ok and not stale. Wrong health and stale value. - RPC genesis not gated (
src/status.ts:243): the RPC genesis counts toward reset_detected false even when the read errored, is 9 days old, or is dated after the snapshot. RULES.md §1 doesn't state such a gate for the RPC, so this is partly a spec gap. Wrong reset value. - Page with a non-UTF-8 name dropped silently (
src/source.ts:111): escrow reads funded over a finalized release in that page. TypeScript says partial, Python says complete with the release counted. Wrong escrow state, and the two disagree. - Broken page chain ignored (
src/escrow.ts:225): a missingnext_pagestill gives funded, while the census calls the chain broken. Wrong escrow state. - Free text on the page passes (
scripts/consistency.mjs:181): a "reset detected / false" row made of two th cells, a note paragraph, a second h1, or a lone th all pass with 0 failures. The real cell still says true. Wrong value shown on the page.
Low and info
- Page:
aria-labelwith any value passes. - Status: unsafe-integer heights read ok; when the previous reading time doesn't parse, the stuck check is skipped and health still reads ok.
- Escrow: one clean release plus an unparsable release gives claimed (the refund case behaves the same).
- Recount: it crashes on deep nesting and refuses integers over 4300 digits, where TypeScript counts.
- Tooling: the source-scan gaps; the mutation runner fails closed when the temp folder is behind a symlink; mutant replacement text expands
$&.

highRollback check reads only the last log line: one snapshot with no RPC reading in between hides a finalized-height rollback, and RPC health reads okobservatory/src/cli.ts:156
RULES.md 1.1 says: when there is a previous snapshot on the same genesis, there must be no rollback, no changed finalized hash and no stuck height. cli.ts takes only readSnapshots(log).at(-1). If that snapshot has no RPC genesis or finalized head (the RPC was not read or the read failed), previous stays null and all three checks are skipped.
The next snapshot's RPC health is then ok even though its finalized height is below the one recorded two lines earlier on the same genesis. So fix 4 (finding 4 of a24f9aa1) is only partly done.
Impact: WRONG HEALTH (ok after a rollback, conflicts empty). Reproduced by running.
Fix: walk the verified log back to the latest snapshot whose status has an RPC genesis equal to the current one and a finalized head, or carry the highest finalized head seen per genesis.
A finalized height stuck across many snapshots is never reported: the stuck time is measured only since the immediately previous snapshotobservatory/src/status.ts:174
RULES.md 1.1 says there must be no finalized height stuck for longer than the stale limit (120 s), and rpc.stale is true when the height is stuck. classifyRpc measures the stuck time as now minus the previous snapshot's observed_at. With snapshots taken more often than the limit, the height can stay at one value forever and every snapshot sees only 60 s.
Impact: WRONG HEALTH and stale value (ok/false while the height has not moved for 4+ minutes). interfaces/README tells Seat Court to use rpc.stale for deadlines. Reproduced by running.
Fix: carry forward the time a finalized head was first seen (walk back through consecutive snapshots with the same height and hash, or store finalized_since in the status).
RPC genesis counts toward reset_detected=false even when the RPC read failed, is days old, or is later than the snapshot (no gate like the faucet /chain one)observatory/src/status.ts:243
A page file whose name holds a non-UTF-8 byte is silently dropped: escrow reads funded over a finalized release, the TypeScript census shows a gap, Python counts the page as completeobservatory/src/source.ts:111
readdirSync decodes an invalid UTF-8 file name to U+FFFD. The entry passes the clause 15 checks, but join(dir, name) names a path that does not exist, so read() returns undefined at
!existsSync(path)and adds nothing to loadErrors or pageErrors. RULES.md section 2 and clause 12 say a page that cannot be read leaves every escrow unverified and refuses the census.Instead the escrow is judged without the page. tools/recount.py lists the directory with os.listdir (surrogateescape), reads the page and calls the census complete.
Impact: WRONG ESCROW STATE (funded although the input holds a finalized release) and a TypeScript/Python disagreement on completeness and totals. Reproduced by running.
Fix: list with encoding 'buffer' and a strict decode, or treat a missing file for a listed entry as a page error. Never return undefined silently for an entry the listing produced.
Escrow ignores page chains: an open on a page whose next_page is not in the input reads funded, while the census calls the same chain brokenobservatory/src/escrow.ts:225
Section 2 makes every escrow unverified when a page could not be read, because the missing page could hold a conflicting event. escrowState only checks each page with pageProblem() and never walks page chains. A page that names a next_page missing from the input is not treated as missing, so an open on page 0 with next_page 1 absent gives funded, though page 1 could hold the release or refund. The census over the same input reports a broken chain and a 100-block gap.
The rule names only unreadable and invalid pages, so this is a spec gap too, but its stated reason applies.
Impact: WRONG ESCROW STATE (funded while the evidence that could contradict it is known to be missing). Reproduced by running.
Fix: apply census clause 2 to escrow pages (a broken chain on the pinned genesis, or disagreeing copies of a page number, makes every escrow unverified with a note), and state it in RULES.md 2.

Round 5 says src/strict.ts holds the one safe-integer reading for escrow, census and status. status.ts nonNegativeInt still uses Number.isInteger, so a head whose finalized number JSON.parse has rounded is accepted as present and valid. Its lag is computed from rounded values, and the height becomes the escrow evidence bound. Merged from audit_math and audit_permissions.

Expected: rpc degraded ('no valid finalized head', 'no valid best height'), finalized_height null.When the previous snapshot's RPC reading time does not parse, the stuck-height check silently does not run and RPC health is okobservatory/src/status.ts:175
RULES.md 1.1: ok needs every check to run and pass. cli.ts passes the previous snapshot's rpc.observed_at whenever it is non-null, and the status stores the raw head time even when it does not parse (here a zoneless time, which already made that snapshot unknown). In the next snapshot with the same finalized head, secondsBetween returns null and the stuck branch is skipped without marking the check as unable to run.
Impact: wrong health (ok while the height may have been stuck for 70 minutes). Reproduced by running.
Fix: when previous is on the same genesis with the same head and its time does not parse, health unknown, or only take a previous whose observed_at parses.
A finalized release (or refund) with an unparsable escrow id does not block claimed (or refunded), though a second well-formed release of the same kind makes the escrow unverifiedobservatory/src/escrow.ts:383
Section 2: an unparsable finalized terminal on the pinned genesis could contradict any escrow, and more than one distinct finalized release is a conflict (line 376). The claimed branch checks suspectTerminals only for REFUNDED, and the refunded branch only for RELEASED. So one clean release plus one unparsable finalized release gives claimed, while one clean release plus a second clean release gives unverified.
More conflicting evidence gives a more confident answer.
Impact: WRONG ESCROW STATE (claimed/refunded) in a conflicting-evidence case. Reproduced by running.
Fix: in the claimed branch also treat suspectTerminals.has(RELEASED) as a conflict (REFUNDED in the refunded branch), or state the exception in RULES.md.

RULES.md 4 says the scan fails any src module that uses process.getBuiltinModule, process.binding, eval or Function, and computed access, so that an aliased or computed form cannot slip past. The regexes match only literal spellings, and readdirSync(dir) is not recursive while tsconfig compiles everything under src.
The runtime block in test/setup.ts still catches these if a test runs them, so this is a gap in the static layer, not a live path; no current src file uses these forms. Fix 13 is partly done.
Impact: no current network/sign/spend path. Reproduced by running the scan's own regex list.
Fix: scan recursively and ban
process[,Reflect.get(process,Reflect.and.constructor.constructorin src.Mutation runner fails every control when the temp folder is reached through a symlink, so 206 of 206 cannot be shown there (fails closed)observatory/scripts/mutate.mjs:43
The work folder comes from os.tmpdir() without realpath. Vitest reports test file names by real path, and relative(copyPkg, f.name) then gives '../../../../realtmp/...', so the control marks every file missing and every mutant 'error'. It fails closed (no false pass), but on stock macOS (/var/folders -> /private/var) the mutants step always exits 1. mutate-canary.mjs and canary.mjs use the same pattern.
Reproduced by running.
Fix: realpathSync(mkdtempSync(...)).
mkdir /tmp/realtmp; ln -s /tmp/realtmp /tmp/symtmp;
TMPDIR=/tmp/symtmp node scripts/mutate.mjs mutants/census.json-> exit 1, control_before {outcome:'control-fail', exit:0, files:[{file:'../../../../realtmp/obs-mutate-*/repo/observatory/test/census.test.ts', status:'passed', tests:162}], missing:['test/census.test.ts']}, summary killed 0, other 31. Expected: control-pass and 31 killed, as without the symlink.Mutation runner applies mutants with String.prototype.replace, which expands $& / $' / $` / $$ in the replacementobservatory/scripts/mutate.mjs:160
original.replace(m.find, m.replace) with a string pattern still expands $-patterns in the replacement, so a future mutant containing $& would be written differently from what mutants.json records. No current mutant has such a sequence, so no present result is wrong. Found by reading; the replace behaviour was reproduced.
Fix: original.replace(m.find, () => m.replace) or split/join.
node -e 'console.log("a+b".replace("b","$&$&"))'-> a+bb (not a+$&$&). A mutant {find:'b', replace:'$&$&'} would write 'bb'.
