Each commit references the issue individually

This PR covers various issues, all linked in the individual commits. It adds basic processing of post content CSV files, limits imports to 100 posts (while in development, this will be removed later), and lays the foundation for future milestones.

  • CSV import engine — Uploading a title/html/published_at CSV to POST /posts/upload/ now creates real posts instead of a no-op 202. Rows are parsed in-request, then written by an in-process background job via models.Post.add under {importing: true}; html is converted to lexical, slugs are set as a slugified title, and a file that can't be parsed as CSV at all is rejected with a 422.
  • Temporary 100-post cap — Files with more than 100 rows are rejected with a clear 422 before anything is written. A hard-coded constant with a single check, deliberately with no config surface — the whole limit goes away when the durable job system lands.
  • Dates come from the CSV — The one date column sets published_at, created_at and updated_at, so imported archives look written when they were written, not created at import time.
  • In-memory outcome tracking — Each import registers a run in an in-memory store recording one outcome per row (status, source line number, title, post id/URL); the 202 body returns the run's import_id and row total. This is what the completion-report milestone will render from; nothing is persisted until the durable job system.
  • Bad rows don't kill the run — A malformed row (missing/overlong title, invalid date, unconvertible html) is skipped on its own with an actionable reason; the rest of the file still imports. Skipped (fix the file) is distinguished from failed (write attempted and lost).
  • Defaults for absent fields — Imported posts land published, public, type post, authored by the site owner, with two internal batch tags: a date stamp (matching the JSON importer's format) and a unique #Import Run <id> tag the report milestones key on.
  • Zero side-effects, pinned — A regression suite proves a bulk import sends no newsletter emails and fires no per-post webhooks, with a positive control so the assertion can't pass vacuously.

Learning: In the TryGhost/Ghost monorepo, treat `tryghost/admin-api-schema` as the single abstraction layer over AJV version differences. Do not raise code review findings for AJV-internal error field changes (e.g., `dataPath` → `instancePath` between AJV v6 and v8) when evaluating Ghost consumer code. The consumer-facing error contract for this package (`ValidationError` with `message`, `property`, `errorDetails`) is expected to remain stable, and Ghost wrapper code should not inspect raw AJV error objects—so review should focus on the stable `ValidationError` shape rather than AJV internals.

Learning: In this TryGhost/Ghost codebase (Tailwind CSS v4), use/accept the v4 suffix form of the important modifier in class names (e.g., `opacity-100!`, `flex!`). Do not flag these as incorrect or inconsistent with the older v3 prefix form (`!opacity-100`), since the suffix form is the established convention and aligns with the generated CSS.

Learning: When reviewing Ghost API behavior for `errors.HostLimitError`, validate the final serialized error payload that the API returns. Specifically, Ghost relocates the `HostLimitError`’s provided `message` into the serialized response’s `context`, and it replaces the serialized `message` with a generic host-limit message. Therefore, do not assume the error option fields (e.g., `message`) are returned unchanged—assert against the serialized payload shape (`context` contains the original message; `message` is the generic host-limit text) rather than the original thrown error fields.

Learning: When handling Zod validation failures for `z.discriminatedUnion('type', ...)`, do not branch logic based on the human-readable `issue.message` text (it’s not a stable contract). Instead, use structured Zod issue fields to detect the specific failure mode—e.g., check `issue.code === 'invalid_union'` and that `issue.path[0] === 'type'` (or the configured discriminator key)—so the behavior remains reliable across Zod versions.

Walkthrough

The pull request adds CSV post importing across the core service, API, and admin migration UI. It parses and validates CSV rows, converts valid rows into published public posts, records per-row outcomes, and retains import-run state. The posts endpoint now awaits imports and returns import metadata. Core boot initializes the content-import service. The admin modal uses CSV-specific processing text. Unit and end-to-end tests cover parsing, validation, import limits, post creation, run retention, and side effects.

Keep the parse failure for diagnosis.

The catch discards the original error. The caller receives only a generic ValidationError, and nothing is logged. An operator cannot tell a malformed upload from a reader defect.

Attach the original error, which report already handles elsewhere in this class.

Add coverage for the 422 parse failure.

This test proves that garbage bytes are accepted with 202 and create no posts. The importer also has a distinct path that rejects an unreadable file with a ValidationError and the message "The file could not be parsed as a CSV file." (ghost/core/core/server/services/content-import/import/importer.ts, Lines 95-101). No e2e test reaches that path, so the 422 response for a parse failure is unverified.

Add a case that makes readRows fail, and assert the 422 status with the parse error message.

As per path instructions, tests should "prove changed behaviour, meaningful error/edge paths, and externally observable contracts".

In `@ghost/core/core/server/services/content-import/import/importer.ts`:
- Around line 95-101: Update the catch around _readRows in the importer to
capture the original error and attach it to the ValidationError using the
existing report mechanism, while preserving the unreadableFile validation
message.

In `@ghost/core/test/e2e-api/admin/posts-importer.test.js`:
- Around line 243-261: Add an e2e importer test that forces readRows to fail
while uploading a posts file, then assert the endpoint returns 422 and includes
“The file could not be parsed as a CSV file.” Reuse the existing posts upload
setup and test helpers near the garbage-file case, focusing on the externally
visible parse-failure response.

File: ghost/core/core/server/api/endpoints/member-comment-ban.js:64-68
Timestamp: 2026-01-08T10:26:38.700Z
Learning: In the Ghost API, endpoints rely on the serialization layer to prepare frame.data[docName] as a non-empty array before query() executes. Endpoints access frame.data[docName][0] directly (e.g., frame.data.comment_bans[0], frame.data.members[0], frame.data.posts[0]) without per-endpoint validation. This pattern is common across API endpoints. When maintaining or creating endpoints, avoid duplicating validation for frame.data[docName] and ensure the serializer guarantees the shape and non-emptiness. If you add a new endpoint that uses this frame.data[docName], follow the same assumption and avoid redundant checks unless there's a documented exception.

Timestamp: 2026-02-04T15:58:09.124Z
Learning: In Ghost core tests and code that interact with the Ghost comments API, count.replies is a backward-compatible alias for count.total_replies (all descendants via parent_id) and does not represent direct replies. The new field count.direct_replies returns tree-native direct reply counts. Reviewers should verify any code paths, tests, or API surface areas that rely on count.replies are preserved for compatibility, and consider updating or adding tests to cover count.direct_replies for direct counts. When updating or adding tests, ensure behavior is documented and that any assertions reflect the distinction between total (including descendants) and direct reply counts to avoid regressions in API consumer expectations.

Learning: In the TryGhost/Ghost monorepo, treat `tryghost/admin-api-schema` as the single abstraction layer over AJV version differences. Do not raise code review findings for AJV-internal error field changes (e.g., `dataPath` → `instancePath` between AJV v6 and v8) when evaluating Ghost consumer code. The consumer-facing error contract for this package (`ValidationError` with `message`, `property`, `errorDetails`) is expected to remain stable, and Ghost wrapper code should not inspect raw AJV error objects—so review should focus on the stable `ValidationError` shape rather than AJV internals.

Learning: When using Express.js view engines, Express stores engine handler functions in `app.engines` with keys that include a leading dot (e.g., `app.engines['.hbs']` and `app.engines['.ejs']`). Therefore, checking `app.engines.hbs` (no dot) will be `undefined`; to test whether an engine is already registered, use bracket notation with the dot prefix: `app.engines['.hbs'] !== undefined` (or equivalently `Object.prototype.hasOwnProperty.call(app.engines, '.hbs')`).

Learning: When reviewing Ghost API behavior for `errors.HostLimitError`, validate the final serialized error payload that the API returns. Specifically, Ghost relocates the `HostLimitError`’s provided `message` into the serialized response’s `context`, and it replaces the serialized `message` with a generic host-limit message. Therefore, do not assume the error option fields (e.g., `message`) are returned unchanged—assert against the serialized payload shape (`context` contains the original message; `message` is the generic host-limit text) rather than the original thrown error fields.

Learning: When handling Zod validation failures for `z.discriminatedUnion('type', ...)`, do not branch logic based on the human-readable `issue.message` text (it’s not a stable contract). Instead, use structured Zod issue fields to detect the specific failure mode—e.g., check `issue.code === 'invalid_union'` and that `issue.path[0] === 'type'` (or the configured discriminator key)—so the behavior remains reliable across Zod versions.

Learning: In Ghost's e2e API tests, audit events should separate the generic operation from the specific action. Assert that event equals the CRUD operation type (e.g., 'edited', 'added', 'deleted') and, if needed, also assert on context.action_name for the exact action (e.g., 'commenting_disabled', 'commenting_enabled'). This makes tests robust to both high-level and specific audit details.

Learning: In tests for the Ghost media-inliner, when reviews reference getMediaStorage withArgs(extension), verify that the extension corresponds to the actual binary content of the nock/mocked response (detected via magic bytes) rather than the URL filename. This applies to all tests under ghost/core/test/unit/server/services/media-inliner (and similar media-inliner tests). Use binary content to determine expected extension (e.g., a GIF blob should yield .gif even if the URL ends with .jpg).

Learning: In the Ghost Admin React app, when you rely on data returned by `useBrowseSite()` (e.g., `site.data?.site.url` in the onboarding flow), assume the hook’s site data is already pre-loaded/cached before the route renders. In this context, the fallback to `"/"` for `site.data?.site.url` should not be treated as a practical runtime path, so avoid adding extra loading guards for `useBrowseSite()` output unless the `useBrowseSite()` preloading/caching guarantee changes.

Added CSV content import engine that writes posts row by row
b1cc34c 
ref https://linear.app/ghost/issue/MIG-1438/import-title-html-publish-date-into-real-posts

Uploading a CSV of title + html + published_at to /posts/upload/ now
produces real posts instead of a no-op 202. The CSV is parsed inside the
request (the uploaded temp file is deleted once the response goes out)
and the rows are written by an in-process background job, one
models.Post.add per row under {importing: true, context: {internal:
true}} so timestamps are preserved and publish side-effects stay
suppressed. Content is converted html→lexical because the model strips
client-supplied html on import and renders html from lexical itself.
A file that cannot be parsed as CSV at all is rejected with a 422.
Slugs are set from the title with the standard slugify rules up
front: the model's own slug pass under options.importing makes only
required changes (it preserves imported slugs), which would keep a
comma title's double dash. A file whose quoting is malformed is
rejected whole rather than imported as glued-together rows.

The new content-import service mirrors the members import-export
structure: an injected-dependency importer behind a composition root, so
the unit suite drives it without a database. The importer modal's
confirmation no longer promises an email for CSV imports — that lands
with the completion-report milestone.
@PaulAdamDavis
Added a temporary 100-post cap to CSV content imports
f0c0d7e 
ref https://linear.app/ghost/issue/MIG-1480/enforce-the-temporary-100-post-cap

While import state lives in an in-memory store, an upload of more than
100 posts is rejected with a clear 422 before anything is written.

The cap is a hard-coded constant and a single length check —
deliberately no config surface, tuning layer, or parse short-circuit,
because the whole limit is deleted once the durable job system lands.
@PaulAdamDavis
Changed CSV content import to date posts entirely from the CSV date
3850ea8 
ref https://linear.app/ghost/issue/MIG-1440/preserve-publish-date-and-updated-at-on-import

The CSV's one date column now sets created_at and updated_at alongside
published_at, so an imported archive looks written when it was written
rather than created at import time. The values only survive because the
write runs under options.importing, which disables the model's own
timestamp stamping — the e2e assertion on created_at/updated_at is what
makes that observable and pins it against regression.

A row without a date leaves all three to the model, which stamps the
import time as before.
@PaulAdamDavis
Added an in-memory record of what each content import row produced
7f69c0e 
ref https://linear.app/ghost/issue/MIG-1443/track-each-rows-outcome-in-the-in-memory-store

Each import now registers a run in an in-memory store and records one
outcome per row — status, the source line number (as a publisher sees
it in a spreadsheet, header on line 1) and title, and the created
post's id and URL — with the run marked complete even when the job
fails partway. This is the object the completion report and error CSV
milestones render from; nothing is persisted, by design, until the
durable job system lands.

The store holds the ten most recent runs for at most an hour, evicted
lazily on the next create so no timer keeps the process alive. The 202
body now carries the run's import_id and row total, which is what a
report will be looked up by.
@PaulAdamDavis
Changed CSV content import to skip a bad row instead of failing the run
30831f5 
ref https://linear.app/ghost/issue/MIG-1442/skip-malformed-rows-without-aborting-the-import

A malformed row — no title, a title over 255 characters, an unparseable
date, or html the converter refuses — is now refused on its own with a
reason a publisher can act on, and the rest of the file still imports.
An invalid date skips the row rather than being silently replaced with
the import time (what the JSON importer does), because rewriting a
publisher's date is worse than telling them about it.

The outcome record distinguishes skipped (refused before the write; fix
the file) from failed (the write was attempted and lost), since the
publisher's next action differs. A write failure lands in the row's
outcome rather than the error log; only a failure that is nobody's row,
like the converter not loading, is still reported.
@PaulAdamDavis
Added defaults for fields a content import CSV does not carry
6988fc1 
ref https://linear.app/ghost/issue/MIG-1444/hard-coded-defaults-for-unspecified-fields

Imported posts now land published, public, as posts, authored by the
site owner, and filed under two internal batch tags: a date stamp in
the site timezone (the JSON importer's #Import format, so the two read
alike in Admin) and an "#Import Run <id>" tag unique to this run, which
the report milestones key on even across same-minute or concurrent
imports.

Status and visibility are constants rather than omissions: the model
would default status to draft and read visibility from the
default_content_visibility setting, which on a members site would
silently import paid posts (pinned by a test). Scheduled is never
written because the post scheduler listens for it with no importing
check. The owner authorship costs nothing — the model resolves the
import's internal context to the owner — so no authors key is sent.
@PaulAdamDavis
Added a regression test pinning that CSV imports send nothing
79946ff 
ref https://linear.app/ghost/issue/MIG-1439/suppress-publish-side-effects-on-import-zero-emailswebhooks-regression

A bulk import must send zero newsletter emails and fire zero per-post
webhooks. Both are already true — webhook, Slack, IndexNow and mention
consumers all stand down on options.importing, and a newsletter can
only be attached in the API layer the importer never goes through —
but each is one deleted `if` away from silently breaking. This suite
turns those facts into failures: post.published and post.added are
armed against a mock receiver, a CSV is imported, and nothing may
arrive; the emails table must stay empty.

A positive control publishes through the API and asserts the webhook
does fire, so a broken mock can't make the import test pass vacuously.
The importer now carries a comment naming each consumer its options
keep quiet.

Moved shared settings code out of the settings quarantine (#30113)
9866fce 
no ref

The settings shell and the shared `components/`, `hooks/`, `utils/`,
`data/`, `assets/` and `providers/` now live directly under `settings/`,
leaving only `advanced/` in `settings/app/` until the PRs touching it
land (#30018, #30019, #29916, #30054, #30099, #30110, #28368). Big diff,
but ~300 of the 325 files are import-line rewrites; the substantive
changes are the lint-debt fixes the move surfaces:

- shell files grouped in `settings/layout/`: `app.tsx` (provider tree),
`main-content.tsx`, `sidebar.tsx`, `settings-sections.tsx` (was
`components/settings.tsx`); root `settings.tsx` route entry unchanged
- contexts split the way admin's other contexts are — hooks + context in
`*-context.ts`, provider component in its own file — for global data,
settings app, confirmations, scroll sections; `withErrorBoundary` →
`with-error-boundary.tsx`
- `loadKoenig` → `components/koenig-loader.ts`; the untyped
`@tryghost/koenig-lexical` bundle gets a minimal `KoenigLexicalModule`
type instead of `any`
- `@tryghost/limit-service` and `@tryghost/nql` get typed ambient
declarations in `vite-env.d.ts` (clears ~25 `no-unsafe-*` in
`use-limiter`)
- `iframe-buffering` reuses `utils/debounce`; `TopLevelGroup.saveState`
uses the framework's `SaveState`; the usual `void`-wrapping of async
handlers

Validate the timezone value before applying the fallback.

z.string().min(1) accepts values such as Not/AZone. The .catch('Etc/UTC') fallback then does not run. getTimezone() passes that invalid value to buildImportTagNames().

Add an IANA timezone refinement before .catch().

As per coding guidelines, “Boundary data ... env/config ... is unknown until validated — Zod by default.”

- Around line 9-10: Update timezoneSchema to validate that the string is a valid
IANA timezone before applying the existing Etc/UTC catch fallback, so invalid
values such as Not/AZone are replaced with UTC before getTimezone() passes them
to buildImportTagNames().

File: ghost/core/core/server/api/endpoints/member-comment-ban.js:64-68
Timestamp: 2026-01-08T10:26:38.700Z
Learning: In the Ghost API, endpoints rely on the serialization layer to prepare frame.data[docName] as a non-empty array before query() executes. Endpoints access frame.data[docName][0] directly (e.g., frame.data.comment_bans[0], frame.data.members[0], frame.data.posts[0]) without per-endpoint validation. This pattern is common across API endpoints. When maintaining or creating endpoints, avoid duplicating validation for frame.data[docName] and ensure the serializer guarantees the shape and non-emptiness. If you add a new endpoint that uses this frame.data[docName], follow the same assumption and avoid redundant checks unless there's a documented exception.

Timestamp: 2026-02-04T15:58:09.124Z
Learning: In Ghost core tests and code that interact with the Ghost comments API, count.replies is a backward-compatible alias for count.total_replies (all descendants via parent_id) and does not represent direct replies. The new field count.direct_replies returns tree-native direct reply counts. Reviewers should verify any code paths, tests, or API surface areas that rely on count.replies are preserved for compatibility, and consider updating or adding tests to cover count.direct_replies for direct counts. When updating or adding tests, ensure behavior is documented and that any assertions reflect the distinction between total (including descendants) and direct reply counts to avoid regressions in API consumer expectations.

Learning: In the TryGhost/Ghost monorepo, treat `tryghost/admin-api-schema` as the single abstraction layer over AJV version differences. Do not raise code review findings for AJV-internal error field changes (e.g., `dataPath` → `instancePath` between AJV v6 and v8) when evaluating Ghost consumer code. The consumer-facing error contract for this package (`ValidationError` with `message`, `property`, `errorDetails`) is expected to remain stable, and Ghost wrapper code should not inspect raw AJV error objects—so review should focus on the stable `ValidationError` shape rather than AJV internals.

Learning: When using Express.js view engines, Express stores engine handler functions in `app.engines` with keys that include a leading dot (e.g., `app.engines['.hbs']` and `app.engines['.ejs']`). Therefore, checking `app.engines.hbs` (no dot) will be `undefined`; to test whether an engine is already registered, use bracket notation with the dot prefix: `app.engines['.hbs'] !== undefined` (or equivalently `Object.prototype.hasOwnProperty.call(app.engines, '.hbs')`).

Learning: When reviewing Ghost API behavior for `errors.HostLimitError`, validate the final serialized error payload that the API returns. Specifically, Ghost relocates the `HostLimitError`’s provided `message` into the serialized response’s `context`, and it replaces the serialized `message` with a generic host-limit message. Therefore, do not assume the error option fields (e.g., `message`) are returned unchanged—assert against the serialized payload shape (`context` contains the original message; `message` is the generic host-limit text) rather than the original thrown error fields.

Learning: In the Ghost Admin React app, when you rely on data returned by `useBrowseSite()` (e.g., `site.data?.site.url` in the onboarding flow), assume the hook’s site data is already pre-loaded/cached before the route renders. In this context, the fallback to `"/"` for `site.data?.site.url` should not be treated as a practical runtime path, so avoid adding extra loading guards for `useBrowseSite()` output unless the `useBrowseSite()` preloading/caching guarantee changes.

Learning: Admin UI in Ghost is intentionally not localized. During code review, do not request adding i18n/translation hooks, wrappers, or new locale keys (e.g., updates to `packages/i18n/locales/en/ghost.json`) for Admin UI strings, including any React components under `apps/admin/src/`.

Learning: When implementing custom error-toast flows in the Admin application, preserve the framework's default dismissal behavior by calling parameterless `toast.dismiss()` before showing the replacement toast. Then call `handleError(error, {withToast: false})` when framework error handling is needed without displaying its default toast.

Learning: When handling Zod validation failures for `z.discriminatedUnion('type', ...)`, do not branch logic based on the human-readable `issue.message` text (it’s not a stable contract). Instead, use structured Zod issue fields to detect the specific failure mode—e.g., check `issue.code === 'invalid_union'` and that `issue.path[0] === 'type'` (or the configured discriminator key)—so the behavior remains reliable across Zod versions.

Timestamp: 2026-01-26T13:53:03.597Z
Learning: In Ghost's e2e API tests, audit events should separate the generic operation from the specific action. Assert that event equals the CRUD operation type (e.g., 'edited', 'added', 'deleted') and, if needed, also assert on context.action_name for the exact action (e.g., 'commenting_disabled', 'commenting_enabled'). This makes tests robust to both high-level and specific audit details.

Learning: In tests for the Ghost media-inliner, when reviews reference getMediaStorage withArgs(extension), verify that the extension corresponds to the actual binary content of the nock/mocked response (detected via magic bytes) rather than the URL filename. This applies to all tests under ghost/core/test/unit/server/services/media-inliner (and similar media-inliner tests). Use binary content to determine expected extension (e.g., a GIF blob should yield .gif even if the URL ends with .jpg).

Validate the time-zone identifier before applying the fallback.

z.string().min(1).catch('Etc/UTC') accepts invalid non-empty values such as Invalid/Zone. moment(now).tz(timezone) then falls back to the host’s local time zone instead of UTC. Validate the identifier with moment.tz.zone() or an equivalent IANA time-zone check before applying .catch('Etc/UTC').

reworks one (rewritten logic or significant new functions — not renames or
small fixes), you may leave ONE optional, non-blocking note for the whole PR
that those files are cheap TS-conversion candidates; skip minor changes and
exempt areas.
If the PR adds or changes a runtime boundary (parsing HTTP input, JSON, config,
external responses), suggest validating it — ideally with TS + Zod.

Learning: In the Ghost Admin React app, when you rely on data returned by `useBrowseSite()` (e.g., `site.data?.site.url` in the onboarding flow), assume the hook’s site data is already pre-loaded/cached before the route renders. In this context, the fallback to `"/"` for `site.data?.site.url` should not be treated as a practical runtime path, so avoid adding extra loading guards for `useBrowseSite()` output unless the `useBrowseSite()` preloading/caching guarantee changes.

Timestamp: 2026-01-08T10:26:38.700Z
Learning: In the Ghost API, endpoints rely on the serialization layer to prepare frame.data[docName] as a non-empty array before query() executes. Endpoints access frame.data[docName][0] directly (e.g., frame.data.comment_bans[0], frame.data.members[0], frame.data.posts[0]) without per-endpoint validation. This pattern is common across API endpoints. When maintaining or creating endpoints, avoid duplicating validation for frame.data[docName] and ensure the serializer guarantees the shape and non-emptiness. If you add a new endpoint that uses this frame.data[docName], follow the same assumption and avoid redundant checks unless there's a documented exception.

Learning: In Ghost core tests and code that interact with the Ghost comments API, count.replies is a backward-compatible alias for count.total_replies (all descendants via parent_id) and does not represent direct replies. The new field count.direct_replies returns tree-native direct reply counts. Reviewers should verify any code paths, tests, or API surface areas that rely on count.replies are preserved for compatibility, and consider updating or adding tests to cover count.direct_replies for direct counts. When updating or adding tests, ensure behavior is documented and that any assertions reflect the distinction between total (including descendants) and direct reply counts to avoid regressions in API consumer expectations.

Learning: In the TryGhost/Ghost monorepo, treat `tryghost/admin-api-schema` as the single abstraction layer over AJV version differences. Do not raise code review findings for AJV-internal error field changes (e.g., `dataPath` → `instancePath` between AJV v6 and v8) when evaluating Ghost consumer code. The consumer-facing error contract for this package (`ValidationError` with `message`, `property`, `errorDetails`) is expected to remain stable, and Ghost wrapper code should not inspect raw AJV error objects—so review should focus on the stable `ValidationError` shape rather than AJV internals.

Therefore, checking `app.engines.hbs` (no dot) will be `undefined`; to test whether an engine is already registered, use bracket notation with the dot prefix: `app.engines['.hbs'] !== undefined` (or equivalently `Object.prototype.hasOwnProperty.call(app.engines, '.hbs')`).

Learning: When reviewing Ghost API behavior for `errors.HostLimitError`, validate the final serialized error payload that the API returns. Specifically, Ghost relocates the `HostLimitError`’s provided `message` into the serialized response’s `context`, and it replaces the serialized `message` with a generic host-limit message. Therefore, do not assume the error option fields (e.g., `message`) are returned unchanged—assert against the serialized payload shape (`context` contains the original message; `message` is the generic host-limit text) rather than the original thrown error fields.

Learning: When handling Zod validation failures for `z.discriminatedUnion('type', ...)`, do not branch logic based on the human-readable `issue.message` text (it’s not a stable contract). Instead, use structured Zod issue fields to detect the specific failure mode—e.g., check `issue.code === 'invalid_union'` and that `issue.path[0] === 'type'` (or the configured discriminator key)—so the behavior remains reliable across Zod versions.

Learning: In Ghost's e2e API tests, audit events should separate the generic operation from the specific action. Assert that event equals the CRUD operation type (e.g., 'edited', 'added', 'deleted') and, if needed, also assert on context.action_name for the exact action (e.g., 'commenting_disabled', 'commenting_enabled').
