# B.29 outcome.* _Peios / Using Peios / Events / Field Index_ > Every field the evman catalogue defines under outcome: its type, values and meaning, and the events that carry it. Every field the catalogue defines under `outcome`, in path order. Each entry gives the field's definition and, under **Carried by**, every event type that writes it. ## B.29.1 `outcome.address` - **Type:** `uint` - **Asserted:** no - **Carried in:** the payload - **Defined in:** `kernel.evman` The user-space address that faulted when the kernel tried to copy from or to it. Meaningful only within the faulting process's address space, and only until that address space changes. **Carried by:** No event carries this field yet. ## B.29.2 `outcome.cleanup` - **Type:** `str.enum` - **Values:** `succeeded` · `failed` · `declined` - **Set:** closed - **Asserted:** no - **Carried in:** the payload - **Defined in:** `kernel.evman` The outcome of the compensating action StrataFS took to undo part of a failed operation, such as removing an object it had just created. `declined` means StrataFS deliberately did not undo it, because the name no longer referred to the object it had created and removing it could have removed someone else's. Both `failed` and `declined` leave an object behind in the stratum that nothing in the merged view accounts for. **Carried by:** No event carries this field yet. ## B.29.3 `outcome.data-lost` - **Type:** `bool` - **Asserted:** no - **Carried in:** the payload - **Defined in:** `kernel.evman` Whether the outcome a record describes destroyed data, rather than only failing to do what was asked. Set this aside from ordinary failures: a data-losing outcome is not recovered by retrying. **Carried by:** No event carries this field yet. ## B.29.4 `outcome.deferred` - **Type:** `bool` - **Asserted:** no - **Carried in:** the payload - **Defined in:** `kernel.evman` Whether a refusal was raised after the caller had already been told the operation succeeded. A deferred refusal has nobody left to receive an error, which is why it is recorded unconditionally rather than only for the arrangement errors. **Carried by:** - [`stratafs.mutation.refused`](/peios/using-peios/events/stratafs/stratafs-mutation-refused.md) ## B.29.5 `outcome.detail` - **Type:** `str` - **Asserted:** no - **Carried in:** the payload - **Defined in:** `kernel.evman` Free text about the outcome, for a person to read. Optional, and never parsed: anything a consumer would filter on belongs in `outcome.reason` or a field of its own. Never the output of a language's debug formatter. **Carried by:** - [`eventd.store.quarantined`](/peios/using-peios/events/eventd/eventd-store-quarantined.md) - [`peinit.config.reload.applied`](/peios/using-peios/events/peinit/peinit-config-reload-applied.md) - [`peinit.critical-service.failed`](/peios/using-peios/events/peinit/peinit-critical-service-failed.md) - [`peinit.graph.validation.failed`](/peios/using-peios/events/peinit/peinit-graph-validation-failed.md) - [`peinit.job.ended`](/peios/using-peios/events/peinit/peinit-job-ended.md) - [`peinit.operation.ended`](/peios/using-peios/events/peinit/peinit-operation-ended.md) - [`peinit.recovery.entered`](/peios/using-peios/events/peinit/peinit-recovery-entered.md) - [`peipkg.action.authorised`](/peios/using-peios/events/peipkg/peipkg-action-authorised.md) - [`peipkg.claim.changed`](/peios/using-peios/events/peipkg/peipkg-claim-changed.md) - [`peipkg.package.installed`](/peios/using-peios/events/peipkg/peipkg-package-installed.md) - [`peipkg.package.uninstalled`](/peios/using-peios/events/peipkg/peipkg-package-uninstalled.md) - [`peipkg.package.upgraded`](/peios/using-peios/events/peipkg/peipkg-package-upgraded.md) - [`peipkg.repository.added`](/peios/using-peios/events/peipkg/peipkg-repository-added.md) - [`peipkg.repository.removed`](/peios/using-peios/events/peipkg/peipkg-repository-removed.md) - [`peipkg.transaction.recovered`](/peios/using-peios/events/peipkg/peipkg-transaction-recovered.md) ## B.29.6 `outcome.errno` - **Type:** `int.errno` - **Asserted:** no - **Carried in:** the payload - **Defined in:** `kernel.evman` The error the operation failed with, as a negative errno. Absent on success. Present where an event records an outcome that has a specific failure rather than only a boolean. **Carried by:** - [`kacs.audit.descriptor.changed`](/peios/using-peios/events/kacs/kacs-audit-descriptor-changed.md) - [`kacs.caap.policy.changed`](/peios/using-peios/events/kacs/kacs-caap-policy-changed.md) - [`kacs.config.value.rejected`](/peios/using-peios/events/kacs/kacs-config-value-rejected.md) - [`kacs.impersonation.reverted`](/peios/using-peios/events/kacs/kacs-impersonation-reverted.md) - [`kacs.impersonation.started`](/peios/using-peios/events/kacs/kacs-impersonation-started.md) - [`kacs.signature.crypto.failed`](/peios/using-peios/events/kacs/kacs-signature-crypto-failed.md) - [`kmes.buffer.swap.failed`](/peios/using-peios/events/kmes/kmes-buffer-swap-failed.md) - [`kmes.config.refresh.failed`](/peios/using-peios/events/kmes/kmes-config-refresh-failed.md) - [`lcs.audit.backup.ended`](/peios/using-peios/events/lcs/lcs-audit-backup-ended.md) - [`lcs.audit.key.deleted`](/peios/using-peios/events/lcs/lcs-audit-key-deleted.md) - [`lcs.audit.key.descriptor.changed`](/peios/using-peios/events/lcs/lcs-audit-key-descriptor-changed.md) - [`lcs.audit.key.hidden`](/peios/using-peios/events/lcs/lcs-audit-key-hidden.md) - [`lcs.audit.key.tombstoned`](/peios/using-peios/events/lcs/lcs-audit-key-tombstoned.md) - [`lcs.audit.restore.ended`](/peios/using-peios/events/lcs/lcs-audit-restore-ended.md) - [`lcs.audit.transaction.committed`](/peios/using-peios/events/lcs/lcs-audit-transaction-committed.md) - [`lcs.audit.value.deleted`](/peios/using-peios/events/lcs/lcs-audit-value-deleted.md) - [`lcs.audit.value.set`](/peios/using-peios/events/lcs/lcs-audit-value-set.md) - [`ntfe.policy.rejected`](/peios/using-peios/events/ntfe/ntfe-policy-rejected.md) - [`peinit.event.dropped`](/peios/using-peios/events/peinit/peinit-event-dropped.md) - [`stratafs.file.copied-up`](/peios/using-peios/events/stratafs/stratafs-file-copied-up.md) - [`stratafs.mutation.refused`](/peios/using-peios/events/stratafs/stratafs-mutation-refused.md) ## B.29.7 `outcome.errno-cleanup` - **Type:** `int.errno` - **Asserted:** no - **Carried in:** the payload - **Defined in:** `kernel.evman` The error a compensating action failed with, when an operation failed and its undo failed too. Read with `outcome.errno`, the error of the operation itself: the pair is how orphaned objects come to exist. Absent when the undo succeeded or was not attempted. **Carried by:** No event carries this field yet. ## B.29.8 `outcome.errno-masked` - **Type:** `int.errno` - **Asserted:** no - **Carried in:** the payload - **Defined in:** `kernel.evman` The error an underlying step actually failed with, where StrataFS returned a different one to the caller. `outcome.errno` holds the error the caller saw; this field holds the one it replaced, which is usually the one that explains the failure. **Carried by:** No event carries this field yet. ## B.29.9 `outcome.fallback` - **Type:** `bool` - **Asserted:** no - **Carried in:** the payload - **Defined in:** `kernel.evman` Whether the operation took a fallback path because the mechanism it prefers was unavailable. The operation still completed, by a slower or coarser route. **Carried by:** No event carries this field yet. ## B.29.10 `outcome.field` - **Type:** `str` - **Asserted:** no - **Carried in:** the payload - **Defined in:** `kernel.evman` The name of the structure field an error was attributed to, such as the member of an argument structure that was out of range. **Carried by:** No event carries this field yet. ## B.29.11 `outcome.invariant-violated` - **Type:** `bool` - **Asserted:** no - **Carried in:** the payload - **Defined in:** `kernel.evman` Whether an internal invariant was found broken and execution continued anyway. A record with this set describes a state the code assumes cannot happen, so treat whatever follows it on the same mount as suspect. **Carried by:** No event carries this field yet. ## B.29.12 `outcome.offset` - **Type:** `uint` - **Asserted:** no - **Carried in:** the payload - **Defined in:** `kernel.evman` The byte offset within the input at which parsing failed. Read with `outcome.field` where the input is a structure. **Carried by:** No event carries this field yet. ## B.29.13 `outcome.reason` - **Type:** `str.enum` - **Asserted:** no - **Carried in:** the payload - **Defined in:** `kernel.evman` Why the operation resolved the way it did. Each event declares its own values: a list, or a curated subset of a `uapi/pkm/trace.h` family, which carries codes that are never event reasons. A trace code is rendered with the family prefix stripped and case folded, so `KACS_FSR_GRANT_DENY` presents as `grant-deny`, and an investigation escalating from the event stream to a live trace sees the same decision described in the same terms. **Carried by:** - [`authd.logon.attempted`](/peios/using-peios/events/authd/authd-logon-attempted.md) - [`authd.service.attested`](/peios/using-peios/events/authd/authd-service-attested.md) - [`authd.session.ended`](/peios/using-peios/events/authd/authd-session-ended.md) - [`kacs.audit.handle.used`](/peios/using-peios/events/kacs/kacs-audit-handle-used.md) - [`kacs.caap.sacl.skipped`](/peios/using-peios/events/kacs/kacs-caap-sacl-skipped.md) - [`kacs.config.value.rejected`](/peios/using-peios/events/kacs/kacs-config-value-rejected.md) - [`kacs.descriptor.rejected`](/peios/using-peios/events/kacs/kacs-descriptor-rejected.md) - [`kacs.impersonation.started`](/peios/using-peios/events/kacs/kacs-impersonation-started.md) - [`lcs.audit.transaction.committed`](/peios/using-peios/events/lcs/lcs-audit-transaction-committed.md) - [`lcs.source.response.rejected`](/peios/using-peios/events/lcs/lcs-source-response-rejected.md) - [`lpsd.account.created`](/peios/using-peios/events/lpsd/lpsd-account-created.md) - [`lpsd.account.deleted`](/peios/using-peios/events/lpsd/lpsd-account-deleted.md) - [`lpsd.account.modified`](/peios/using-peios/events/lpsd/lpsd-account-modified.md) - [`lpsd.credential.changed`](/peios/using-peios/events/lpsd/lpsd-credential-changed.md) - [`lpsd.credential.verified`](/peios/using-peios/events/lpsd/lpsd-credential-verified.md) - [`lpsd.group.created`](/peios/using-peios/events/lpsd/lpsd-group-created.md) - [`lpsd.group.deleted`](/peios/using-peios/events/lpsd/lpsd-group-deleted.md) - [`lpsd.group.member.added`](/peios/using-peios/events/lpsd/lpsd-group-member-added.md) - [`lpsd.group.member.removed`](/peios/using-peios/events/lpsd/lpsd-group-member-removed.md) - [`ntfe.policy.rejected`](/peios/using-peios/events/ntfe/ntfe-policy-rejected.md) - [`ntfe.verdict.reported`](/peios/using-peios/events/ntfe/ntfe-verdict-reported.md) - [`peinit.boot.downgraded`](/peios/using-peios/events/peinit/peinit-boot-downgraded.md) - [`peinit.critical-service.failed`](/peios/using-peios/events/peinit/peinit-critical-service-failed.md) - [`peinit.fd-store.rejected`](/peios/using-peios/events/peinit/peinit-fd-store-rejected.md) - [`peinit.graph.validation.failed`](/peios/using-peios/events/peinit/peinit-graph-validation-failed.md) - [`peinit.graph.validation.warned`](/peios/using-peios/events/peinit/peinit-graph-validation-warned.md) - [`peinit.notify.rejected`](/peios/using-peios/events/peinit/peinit-notify-rejected.md) - [`peinit.on-failure.suppressed`](/peios/using-peios/events/peinit/peinit-on-failure-suppressed.md) - [`peinit.recovery.entered`](/peios/using-peios/events/peinit/peinit-recovery-entered.md) - [`peipkg.claim.changed`](/peios/using-peios/events/peipkg/peipkg-claim-changed.md) - [`peipkg.package.installed`](/peios/using-peios/events/peipkg/peipkg-package-installed.md) - [`peipkg.package.uninstalled`](/peios/using-peios/events/peipkg/peipkg-package-uninstalled.md) - [`peipkg.package.upgraded`](/peios/using-peios/events/peipkg/peipkg-package-upgraded.md) - [`peipkg.repository.added`](/peios/using-peios/events/peipkg/peipkg-repository-added.md) ## B.29.14 `outcome.result-raw` - **Type:** `int` - **Asserted:** no - **Carried in:** the payload - **Defined in:** `kernel.evman` A raw result from an internal step that was neither zero nor a valid negative errno, recorded instead of being passed on. Deliberately not `outcome.errno`: a value outside the errno range returned from an open could reach the caller as a pointer to a file, so StrataFS converts it to `EIO`, and this field holds what it caught. **Carried by:** No event carries this field yet. ## B.29.15 `outcome.reverted` - **Type:** `bool` - **Asserted:** no - **Carried in:** the payload - **Defined in:** `kernel.evman` Whether a credential change the kernel had prepared was silently undone, so that the call returned success having changed nothing. The caller is told it worked; this is the only record that it did not. **Carried by:** No event carries this field yet. ## B.29.16 `outcome.success` - **Type:** `bool` - **Asserted:** no - **Carried in:** the payload - **Defined in:** `kernel.evman` Whether the operation succeeded. What counts as success narrows per event; read the event's own note before computing a rate over it. **Carried by:** - [`authd.logon.attempted`](/peios/using-peios/events/authd/authd-logon-attempted.md) - [`authd.service.attested`](/peios/using-peios/events/authd/authd-service-attested.md) - [`authd.session.ended`](/peios/using-peios/events/authd/authd-session-ended.md) - [`kacs.audit.access.checked`](/peios/using-peios/events/kacs/kacs-audit-access-checked.md) - [`kacs.audit.descriptor.changed`](/peios/using-peios/events/kacs/kacs-audit-descriptor-changed.md) - [`kacs.audit.handle.used`](/peios/using-peios/events/kacs/kacs-audit-handle-used.md) - [`kacs.audit.privilege.used`](/peios/using-peios/events/kacs/kacs-audit-privilege-used.md) - [`kacs.caap.policy.changed`](/peios/using-peios/events/kacs/kacs-caap-policy-changed.md) - [`kacs.impersonation.reverted`](/peios/using-peios/events/kacs/kacs-impersonation-reverted.md) - [`kacs.impersonation.started`](/peios/using-peios/events/kacs/kacs-impersonation-started.md) - [`kacs.mount.policy.changed`](/peios/using-peios/events/kacs/kacs-mount-policy-changed.md) - [`lcs.audit.backup.ended`](/peios/using-peios/events/lcs/lcs-audit-backup-ended.md) - [`lcs.audit.key.created`](/peios/using-peios/events/lcs/lcs-audit-key-created.md) - [`lcs.audit.key.deleted`](/peios/using-peios/events/lcs/lcs-audit-key-deleted.md) - [`lcs.audit.key.descriptor.changed`](/peios/using-peios/events/lcs/lcs-audit-key-descriptor-changed.md) - [`lcs.audit.key.hidden`](/peios/using-peios/events/lcs/lcs-audit-key-hidden.md) - [`lcs.audit.key.opened`](/peios/using-peios/events/lcs/lcs-audit-key-opened.md) - [`lcs.audit.key.tombstoned`](/peios/using-peios/events/lcs/lcs-audit-key-tombstoned.md) - [`lcs.audit.restore.ended`](/peios/using-peios/events/lcs/lcs-audit-restore-ended.md) - [`lcs.audit.transaction.committed`](/peios/using-peios/events/lcs/lcs-audit-transaction-committed.md) - [`lcs.audit.value.deleted`](/peios/using-peios/events/lcs/lcs-audit-value-deleted.md) - [`lcs.audit.value.set`](/peios/using-peios/events/lcs/lcs-audit-value-set.md) - [`lpsd.account.created`](/peios/using-peios/events/lpsd/lpsd-account-created.md) - [`lpsd.account.deleted`](/peios/using-peios/events/lpsd/lpsd-account-deleted.md) - [`lpsd.account.modified`](/peios/using-peios/events/lpsd/lpsd-account-modified.md) - [`lpsd.credential.changed`](/peios/using-peios/events/lpsd/lpsd-credential-changed.md) - [`lpsd.credential.verified`](/peios/using-peios/events/lpsd/lpsd-credential-verified.md) - [`lpsd.group.created`](/peios/using-peios/events/lpsd/lpsd-group-created.md) - [`lpsd.group.deleted`](/peios/using-peios/events/lpsd/lpsd-group-deleted.md) - [`lpsd.group.member.added`](/peios/using-peios/events/lpsd/lpsd-group-member-added.md) - [`lpsd.group.member.removed`](/peios/using-peios/events/lpsd/lpsd-group-member-removed.md) - [`peinit.config.reload.applied`](/peios/using-peios/events/peinit/peinit-config-reload-applied.md) - [`peinit.graph.operation.ended`](/peios/using-peios/events/peinit/peinit-graph-operation-ended.md) - [`peinit.job.ended`](/peios/using-peios/events/peinit/peinit-job-ended.md) - [`peinit.operation.ended`](/peios/using-peios/events/peinit/peinit-operation-ended.md) - [`peipkg.action.authorised`](/peios/using-peios/events/peipkg/peipkg-action-authorised.md) - [`peipkg.claim.changed`](/peios/using-peios/events/peipkg/peipkg-claim-changed.md) - [`peipkg.package.installed`](/peios/using-peios/events/peipkg/peipkg-package-installed.md) - [`peipkg.package.uninstalled`](/peios/using-peios/events/peipkg/peipkg-package-uninstalled.md) - [`peipkg.package.upgraded`](/peios/using-peios/events/peipkg/peipkg-package-upgraded.md) - [`peipkg.repository.added`](/peios/using-peios/events/peipkg/peipkg-repository-added.md) - [`peipkg.repository.refreshed`](/peios/using-peios/events/peipkg/peipkg-repository-refreshed.md) - [`peipkg.repository.removed`](/peios/using-peios/events/peipkg/peipkg-repository-removed.md) - [`peipkg.transaction.recovered`](/peios/using-peios/events/peipkg/peipkg-transaction-recovered.md) - [`stratafs.file.copied-up`](/peios/using-peios/events/stratafs/stratafs-file-copied-up.md) ## B.29.17 `outcome.verdict` - **Type:** `str.enum` - **Values:** `pass` · `reject` · `drop` - **Set:** closed - **Asserted:** no - **Carried in:** the payload - **Defined in:** `kernel.evman` The decision a policy engine reached, where the decision has more than two states and `outcome.success` cannot express it. `reject` and `drop` both refuse, and differ in whether the refusal is signalled back to the sender or the traffic is discarded silently. **Carried by:** - [`ntfe.verdict.reported`](/peios/using-peios/events/ntfe/ntfe-verdict-reported.md) ## B.29.18 `outcome.verdict-previous` - **Type:** `str.enum` - **Values:** `pass` · `reject` · `drop` - **Set:** closed - **Asserted:** no - **Carried in:** the payload - **Defined in:** `kernel.evman` The verdict a flow's cached judgment held before it was judged again.
