feat(observability): activity log v2 — envelope, process lifecycle, op catalog, support export/analyze (Wave 1 of #3233) - #3235
Conversation
…catalog and support export/analyze (#3234) Every server.log line now carries schemaVersion, pid, instanceId and a per-process seq, stamped at the single physical write boundary and reserved against spoofing through extra. The process writes process.started, process.heartbeat and process.exiting, and closes the log descriptor on every shutdown branch. A generated, drift-tested op catalog closes the op vocabulary. keiko support export writes one redacted JSON-Lines support bundle; keiko support analyze reconstructs per-correlation timelines as a single total order. keiko audit local-state gains --json. ADR-0173 (Proposed) records the contract. Wave 1 of epic #3233. Refs #3234 Refs #3233 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Inline comments:
In `@docs/adr/ADR-0173-server-activity-log-v2-machine-reconstruction-contract.md`:
- Around line 149-152: Clarify the truncation contract so configured
array-length and field-count caps include the appended truncation marker. Update
the wording around array truncation and the synthetic _truncatedFieldCount key
to state that marker space is reserved, and add coverage for both limits
remaining within their bounds.
- Around line 257-260: Update ADR-0173’s D9/D10 and Consequences sections to
define separate process-scoped timelines for events without correlationId,
ordered by seq within each (pid, instanceId) stream, with ts used only as a
best-effort cross-process hint. Reconcile the ordering description with the
analyzer’s pre-v2 fallback, which ranks lifetimes by first file position, and
narrow claims about universal (pid, instanceId, seq) ordering and absent
fallbacks to the defined scope.
- Around line 64-67: Update the ADR’s seq/D2 contract to reflect that nextSeq is
currently scoped per resolved log directory, so ordering and tuple uniqueness
claims apply only within one log directory; alternatively, change the ActiveLog
allocation flow to use one shared allocator across all instances, rotation, and
reinitialization. Also qualify any “gap-free” D2 wording because failed writes
can consume sequence numbers before persistence.
- Around line 263-272: Update the Wave 1 compatibility discussion around the
analyzer and retained v1 logs to define handling for records missing
schemaVersion, pid, instanceId, and seq. Document the file-position fallback and
its limitations, specify that legacy records are surfaced as warnings, or
establish a rotation/retention cutoff before Wave 1; ensure the chosen policy is
explicit and consistent with D8.
- Around line 185-198: The op catalog generator and its drift test must not skip
category-bearing events whose op cannot be statically resolved. Update the
extraction/validation flow described in D6 to require a resolvable literal op
and fail generation or the drift check for unresolved expressions instead of
recording or ignoring “<dynamic>”; retain catalog generation for valid literals.
In `@docs/qa/package-coverage-baseline.json`:
- Line 268: Restore the keiko-ui branches baseline to 81.79 in the coverage
baseline data, and do not accept a regenerated value below that floor; add
coverage as needed before regenerating the baseline.
In `@package.json`:
- Around line 150-151: Add the check:op-catalog script to a required CI job or
aggregate validation workflow so scripts/__tests__/op-catalog-drift.test.mjs
runs during CI and stale generated catalogs fail the pipeline.
In `@packages/keiko-cli/src/state-paths.test.ts`:
- Around line 215-216: Add a test around the logsSubtree ownership
classification that creates an unrecognized file and nested directory beneath
logs/ (including descendants) and asserts they are classified as Keiko-owned,
while also asserting the logs/ boundary itself follows the intended
whole-subtree behavior. Keep the existing recognized-name fixtures unchanged.
In `@packages/keiko-cli/src/state-paths.ts`:
- Around line 521-529: In packages/keiko-cli/src/state-paths.ts lines 521-529,
update logsSubtree to stop claiming the entire logs subtree and use ownsFile to
match only server.log and server-<date>.log rotation files. In
packages/keiko-cli/src/state-paths.test.ts lines 215-329, add a foreign file
under logs/ and assert it is classified as unowned, preserving the intended
ownership boundary.
In `@packages/keiko-cli/src/support-analyze.ts`:
- Around line 118-129: Update extraFields to use a null-prototype accumulator so
"__proto__" is stored as an own property rather than invoking the inherited
setter, while preserving existing filtering and undefined behavior. Add a
regression test in the analyzer tests that processes a line containing
"__proto__": {"polluted": true} and verifies the key appears under extra.
In `@packages/keiko-cli/src/support-export.ts`:
- Around line 39-42: Update toLogFileInfo and readVerbatimLogLines to handle
files that disappear between directory discovery and metadata or content reads:
catch the missing-file error, skip that file, and continue building the support
bundle without exposing raw absolute paths. Preserve the existing
missing-logs-directory behavior in discoverServerLogFiles and ensure
serializeBundleLines tolerates the skipped result.
In `@packages/keiko-cli/src/support.ts`:
- Around line 52-54: Update the analyze help text in support.ts to describe
timeline ordering by process-lifetime first appearance in the input file,
followed by instanceId and seq, rather than by numeric pid. Keep the rest of the
command description and options unchanged.
- Around line 272-276: Guard the export write in the support CLI using the same
failure-handling approach as readAnalyzeSource: catch writeFileSync errors, emit
a content-free user-facing message, and return exit code 1 instead of
propagating the raw filesystem error. Add coverage in the support CLI tests for
an --out path whose parent directory does not exist, asserting exit 1 and no raw
ENOENT text.
In `@packages/keiko-cli/src/ui.ts`:
- Around line 395-426: Update writeProcessExiting so an onShutdown failure is
reported through an independent channel when activityLog or startedAt is
unavailable, instead of being dropped by the early return. Preserve the existing
activity-log extra field when logging is available, and include sufficient
context using the existing error classification without exposing the error
message.
- Around line 332-339: Update the evidence-directory environment propagation
around parsed.evidenceDir so an explicitly resolved --evidence-dir value is
assigned to next.KEIKO_EVIDENCE_DIR for child processes, while retaining the
existing default for unset values and respecting any higher-priority environment
value. Update the related ui.test.ts expectation to cover the propagated
explicit directory.
- Around line 694-743: Update reportProcessStarted and resolveInstallModeKind so
install-mode detection failures are caught instead of propagating through the
successful UI launch; preserve process.started emission and omit installMode
when the probe fails, while recording the failure kind on the log line as
required by the existing logging conventions. Add a regression test that forces
the probe to throw and verifies runUiCli still resolves with process.started
written without installMode.
- Around line 644-679: Update writeHeartbeat and startProcessHeartbeat so each
heartbeat reads the current event-loop delay percentile, resets the histogram
immediately afterward, and then writes the record, ensuring samples do not carry
across intervals. Add a regression test covering interval isolation using the
exported startProcessHeartbeat lifecycle.
In `@packages/keiko-server/src/observability/server-log.ts`:
- Around line 365-373: The ActiveLog nextSeq counter must be process-wide and
gap-free: move sequence state out of per-directory ActiveLog instances, advance
it only after writeRecord completes successfully, and preserve the assigned
value for the persisted record. Update the relevant write flow around
writeRecord and add failure-first tests covering two state directories and a
failed write followed by recovery.
In `@scripts/__tests__/op-catalog-drift.test.mjs`:
- Around line 22-52: Add a negative drift-gate test near the existing “matches
the checked-in file exactly” test that clones the checked-in catalog, then
separately changes an entry’s op value, removes an entry, and reorders entries;
assert each mutated copy is not equal to generateOpCatalog(repoRoot), preserving
the exact value-and-order comparison.
- Around line 31-37: Replace the loop in the test named “emits every non-dynamic
op matching OP_NAME_PATTERN” with independent explicit positive and negative
operation-name examples that pin the intended vocabulary shape, rather than
importing or reusing the production OP_NAME_PATTERN predicate. Keep the drift
and violations tests unchanged.
In `@scripts/generate-op-catalog.mjs`:
- Around line 73-81: Update the catalog generation validation around
SCANNED_PACKAGE_ROOTS to enumerate every packages/*/src directory containing an
op: site and fail closed if any such directory is absent from the configured
roots. Keep the check deterministic and redacted, and add a negative test
proving a missing root or weakened configuration is rejected; update the related
header documentation to describe this package-root gate.
- Around line 244-259: Update resolveLiteralValues and its TERNARY_OF_LITERALS
matching logic to reject ternary candidates whose prefix before the first
top-level question mark contains another question mark or a quoted literal.
Ensure nested ternaries return null so callers record the value as dynamic,
while preserving resolution for simple ternaries and other supported literal
forms.
- Around line 441-450: Update opPropertyEntries to detect whether the op value
is a type annotation based on its surrounding interface, type, or
function-parameter context, and skip those declarations before
resolveLiteralValues; also treat a resolved bare capitalized non-constant
identifier as a type. Preserve instrumentation-site handling for actual values
and existing string annotations.
- Line 142: Replace locale-dependent localeCompare sorting with deterministic
codepoint comparisons in the directory walk and the entry sort within the
catalog generation flow, including the logic around the additional referenced
range. Preserve the existing ordering behavior otherwise.
- Around line 461-469: Update scripts/generate-op-catalog.mjs at lines 355-360
to remove the duplicate newline in skipLineComment while preserving exact
offsets, then have entriesForFile compute one comment-stripped source and pass
it to scanObjectLiteralOps, scanBalanced, and collectConstStrings. Apply the
shared stripped source at scripts/generate-op-catalog.mjs lines 461-469 and
183-201, and clamp scanBalanced depth at zero so comments cannot create false op
entries or corrupt argument splitting.
- Around line 478-487: Update helperCallEntries so an undefined
args[helper.argIndex] is handled fail-closed: emit a dynamic siteEntry or throw
instead of returning an empty array. Preserve normal literal and dynamic
resolution for successfully parsed arguments, using splitTopLevelArgs and
helperCallEntries as the implementation anchors.
- Around line 355-360: Update skipLineComment so it returns the index of the
terminating newline without appending an extra newline; let stripComments’
dispatch loop emit that newline once. Preserve newline alignment for line
comments, block comments, and strings containing //.

Learning: In Keiko TypeScript test files, do not request explicit return type annotations for callbacks passed to typed Vitest `it(...)` and `it.each(...)`. Specifically, avoid adding `: void` or `: Promise<void>` to those callback functions when the ESLint rule `typescript-eslint/explicit-function-return-type` is configured with `allowTypedFunctionExpressions: true` (i.e., typed function expressions are intentionally exempt). Only ask for explicit return types if the ESLint configuration changes; otherwise preserve the existing surrounding test-file style.

Inline comments:
In `@docs/adr/ADR-0173-server-activity-log-v2-machine-reconstruction-contract.md`:
- Around line 98-107: Update the ADR’s “gap-free” contract and surrounding
description so it no longer claims exact failed-write accounting unless
reportServerLogFailure flushes pending suppressed failures during shutdown.
Either implement a shutdown flush for failureNotice.suppressed that emits the
aggregate before exit, or narrow the contract to state that suppressed failures
may remain unreported if recovery or process exit occurs first.
In `@packages/keiko-cli/src/support-export.ts`:
- Around line 43-49: Update toLogFileInfoOrUndefined and
readVerbatimLogLinesOrUndefined to treat only missing-file errors as undefined
results; rethrow other filesystem errors such as EACCES, EISDIR, and EMFILE with
contextual information. If the export contract requires continuing on unreadable
files, preserve the error code in the manifest instead of recording them as
skipped due to rotation pruning.
- Around line 168-180: Update readKeptFiles to append each entry from fileLines
individually instead of spreading the entire array into contentLines, avoiding
argument-count limits for large files. Add a regression test covering a file
with enough lines to exceed the spread-call threshold and assert that every line
is returned.
In `@packages/keiko-cli/src/support.ts`:
- Around line 250-259: Update writeBundleOrExitCode to report the filesystem
error’s code property, such as ENOENT or EACCES, instead of
error.constructor.name, while retaining the existing path-free message and
return code. Update the corresponding assertion in support.test.ts to expect the
error code; keep the not.toContain(badOutPath) assertion unchanged.
In `@packages/keiko-cli/src/ui.test.ts`:
- Around line 1373-1392: Update both waitForShutdown tests that spy on
process.emitWarning to restore the spy with warn.mockRestore() in a finally
block, ensuring cleanup occurs whether the test assertions pass or fail. Keep
the existing test behavior and assertions unchanged.
In `@packages/keiko-server/src/observability/log-redaction.ts`:
- Around line 524-527: Move the MAX_LOG_FIELD_COUNT check in the
Object.entries(value) loop to after the reserved-name and FIELD_NAME_PATTERN
filters, so only eligible fields consume the cap. Add a regression test covering
48 valid fields followed by a reserved or invalid field, verifying no valid
field is dropped and _truncatedFieldCount is not added; ensure it fails before
the implementation change and passes afterward.
In `@packages/keiko-server/src/observability/server-log.test.ts`:
- Around line 277-279: Update the test setup around the mocked filesystem and
sink so each test receives isolated instances without mutating the module-level
fsCalls state. Use a per-test module context or fixture-injected write behavior,
and preserve the dropped-write scenario currently exercised by sink.write.
In `@scripts/__tests__/op-catalog-drift.test.mjs`:
- Around line 194-220: Add regression fixture cases covering both new
isTypeAnnotationValue branches: an interface member using a bare PascalCase type
reference such as op: OpName without a terminating semicolon, and a function
parameter using a string-literal union such as op: "pull" | "put" followed by
another parameter or comma. Assert neither declaration produces an entry while
the real runtime operation remains cataloged.
In `@scripts/generate-op-catalog.mjs`:
- Around line 516-536: Update isTypeAnnotationValue so its parenthesized-value
branch matches only function-type syntax with an arrow after the closing
parenthesis; do not classify arbitrary parenthesized runtime expressions as type
annotations. Let non-function parenthesized values fall through to
resolveLiteralValues so they produce the existing dynamic marker, while
preserving handling of genuine function types.

Learning: When reviewing TypeScript files, do not flag single-quoted string literals as a violation if they match Prettier’s formatter-approved output. Specifically, if Prettier is configured to prefer double quotes but retains a single-quoted literal solely because switching to double quotes would require escaping embedded double quotes, allow the single quotes (i.e., don’t “fix” it beyond what Prettier would produce).

Learning: In Keiko TypeScript test files, do not request explicit return type annotations for callbacks passed to typed Vitest `it(...)` and `it.each(...)`. Specifically, avoid adding `: void` or `: Promise<void>` to those callback functions when the ESLint rule `typescript-eslint/explicit-function-return-type` is configured with `allowTypedFunctionExpressions: true` (i.e., typed function expressions are intentionally exempt). Only ask for explicit return types if the ESLint configuration changes; otherwise preserve the existing surrounding test-file style.

Inline comments:
In `@packages/keiko-cli/src/ui.test.ts`:
- Around line 1420-1432: Remove the order-dependent “leaves no leaked
process.emitWarning spy behind” test. Retain and verify that both
warning-related tests restore their vi.spyOn(process, "emitWarning") spies in
finally blocks, so cleanup occurs even when assertions fail; if needed, extract
this lifecycle into a helper and test the helper directly without relying on
test execution order.
In `@packages/keiko-server/src/observability/server-log.ts`:
- Around line 247-252: Update writeStderrNotice to report stderr write failures
through an independent, redacted error-reporting path instead of silently
swallowing them, preserving correlationId when available. Add a failure-first
test that forces process.stderr.write to throw and verifies the resulting
observable failure behavior.
In `@scripts/generate-op-catalog.mjs`:
- Around line 534-553: Update isTypeAnnotationValue and its callers to use
declaration context so parenthesized function types are recognized only in
TypeScript type annotations, while runtime arrow-function op values such as op:
(value) => value are classified as <dynamic>. Add a regression fixture and
assertion confirming exactly one <dynamic> catalog entry for the runtime
arrow-function case.

Outside diff comments:
In `@packages/keiko-server/src/observability/log-redaction.ts`:
- Around line 530-534: In the log-entry redaction flow, update the logic around
redactLogValue so each field is redacted first and entries whose redacted value
is undefined are skipped before checking MAX_LOG_FIELD_COUNT. Preserve the
existing truncation behavior for retained entries, and add a regression test
covering 48 unsupported values followed by one valid field to verify the valid
field is retained.

Learning: When reviewing TypeScript files, do not flag single-quoted string literals as a violation if they match Prettier’s formatter-approved output. Specifically, if Prettier is configured to prefer double quotes but retains a single-quoted literal solely because switching to double quotes would require escaping embedded double quotes, allow the single quotes (i.e., don’t “fix” it beyond what Prettier would produce).

Learning: In Keiko TypeScript test files, do not request explicit return type annotations for callbacks passed to typed Vitest `it(...)` and `it.each(...)`. Specifically, avoid adding `: void` or `: Promise<void>` to those callback functions when the ESLint rule `typescript-eslint/explicit-function-return-type` is configured with `allowTypedFunctionExpressions: true` (i.e., typed function expressions are intentionally exempt). Only ask for explicit return types if the ESLint configuration changes; otherwise preserve the existing surrounding test-file style.

Superseded by 9f26443: this review targets 6d52089, one revision back. All 39 findings across three review rounds (27 + 9 + 3) were answered in their threads — 36 repaired with a fix reference and a failing-first regression test, 3 refuted with evidence (T6: the op-catalog drift test already runs in npm test and the CI scripts coverage lane; T2: the eight entries are forwarding plumbing whose literal callers are catalogued, with the uncatalogued diagnostic operation vocabulary recorded as a Wave 6 follow-up in #3233; R2-6: the fsCalls fixture and its unconditional afterEach reset predate this PR). Every thread is resolved. Gates on the new head: typecheck, lint, format, arch, adr-index, op-catalog, 31,416 tests, coverage baseline with no floor decreased, gates:sonar PASS; all required GitHub checks green. Dismissing the stale changes-requested state on the superseded head per the repository owner's standing authorization.

Summary
Wave 1 of epic #3233: the activity log becomes a machine-reconstruction contract — the first slice that lets a customer export one artifact and lets an agent order, group and attribute its lines without heuristics.
What ships
Envelope v2 (
packages/keiko-server/src/observability/): every line the file sink writes now carriesschemaVersion: 2,pid,instanceId(8 hex characters minted once per process start — the OS recycles pids across restarts, sopidalone is not a process identity) and a per-process monotonicseq(perActiveLog, survives day rotation). All four are stamped at the single physical write boundary and added toRESERVED_FIELD_NAMES, soextracannot spoof them. The oversized-line fallback keeps them, so the(pid, instanceId, seq)join key never has a gap. The counting pins (oneopenSync, onewriteSyncper line) still hold — stamping adds no syscalls. Array truncation now appends[dropped:length]; field-count truncation adds_truncatedFieldCount: true;unsupportedReasonsis closed structurally throughcloseReasonVocabularyat the projection site instead of by comment.ServerLogCategorygainsprocess.Process lifecycle (
packages/keiko-cli/src/ui.ts):process.started(node version, platform, arch, product version, install mode, host, port,stateDirSourcelabel — never the raw path — resolved log level, provider count),process.heartbeatevery 60 s (RSS, heap, external, event-loop delay p99;unref()'d, stopped on every shutdown branch), andprocess.exiting(reason, uptime) followed bycloseFileServerLogSinks()— a function that was built in #3230 and dead in production until now.KEIKO_EVIDENCE_DIRdefaults to<stateDir>/evidencelikeKEIKO_MEMORY_DIR;logs/is a recognised runtime-state subtree.Op catalog (
scripts/generate-op-catalog.mjs→docs/observability/op-catalog.generated.json): everyopliteral in product code — bothop:properties and the positional helper form the gateway and knowledge lanes actually use — with category, package and call site, pinned by a drift test (npm run check:op-catalog). Category is resolved from the sibling literal, the helper's fixed category, or a file-level singlecategorybinding; 29 of 132 entries remain honestlyunknown(26 inorchestrator.ts, which binds two categories). Zero literals violate the op-name pattern.keiko support export: one JSON-Lines artifact — line 1 is the manifest (product version, platform, node, install mode,stateDirSource,redactionAttested, which log files were copied, which were dropped to honour the 50 MB ceiling, the local-state audit summary with itsstateDirpath projected away, the evidence-index count), every following line a byte-for-byte copy oflogs/server*.log, oldest file first. Nothing is re-serialised, so a re-encoding bug cannot introduce a leak into lines that were already safe on disk.keiko support analyze FILE [--correlation-id ID] [--json]: per-correlation timelines as one total order — process lifetimes ranked by first appearance in the file,seqinside a lifetime, a pre-v2 line by its own position — plus distinct error kinds, first/last timestamps, and a malformed-line count that is reported, never skipped.keiko audit local-state --jsonplus an in-process entry point the exporter composes.ADR-0173 (Proposed) records the contract, the ordering guarantee and its explicit limit, the dist-anchored stack-frame design and no-source-maps rationale (Wave 2), the correlation-threading contract (Wave 3), the artifact format and
ui.logdefault exclusion, the wave plan, and theERROR_KIND_PATTERNrelocation framed as an invariant relocation.keiko-servernow exportscloseFileServerLogSinks,serverLogInstanceId,SERVER_LOG_SCHEMA_VERSION,resolveServerLogThreshold,SERVER_LOG_LEVEL_ENV,DEFAULT_SERVER_LOG_LEVEL,detectUpdateInstallMode,productionUpdateFactsand the log types, so the CLI consumes them instead of local mirrors.How this was built and checked
Twelve parallel readers mapped the surface (36 gaps, 7 blockers), three independent designs were scored by three judges and synthesised, and Wave 1 was implemented by six implementers on disjoint file sets, then reviewed by three adversarial reviewers. The review caught one blocker before it shipped: the manifest embedded the whole
AuditResult, whosestateDiris the absolute state directory with the operator's OS username; it is now projected away with a regression test (fails before, passes after). Two further findings (the catalog generator was blind tokeiko-cli's own new ops; a throwing heartbeat teardown could abort shutdown before the exit line) were fixed the same way.Refs #3234
