WalkthroughThe change adds schema validation, deep freezing, typed access, and rebuild-based overrides for configuration. The loader and test fixtures now use the validated configuration API. The migrator and logging setup receive deep clones of shared configuration. Tests and documentation cover configuration behavior, type checks, and consumer copies.

Default custom environments to warn-only behavior.
The environment schema allows values chosen by an embedder, including staging. When validation fails, env !== 'production' makes those environments throw during createSnapshot, which can prevent startup. Keep strict validation for explicit development and test environments, and retain GHOST_CONFIG_SCHEMA_STRICT as the override.
Proposed correction
- return env !== 'production';
+ return env === 'development' || env === 'test' || env.startsWith('testing');📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

83-83: The lenient path freezes unvalidated subtrees thatget()never serves.If validation fails in a non-strict environment,
rawis the full clone. The clone includes every top-level key, and each key is deep-frozen. This is safe becauseget()reroutes only schema paths. It still freezes and retains a second copy of the full config, including all environment variables. On the success path,result.dataalso keeps unknown keys by reference from the clone. Both paths therefore behave the same way, and the change has no functional impact. No action is required.

no ref
Config is loaded by nconf and read through `config.get('a:b')`, which returns
`any` and hands out a live reference into nconf's stores. There are ~350 such
reads in `ghost/core/core` across 78 top-level keys, so validating all of it at
once is not a change anyone could review or safely ship.
The schema is therefore allowed to grow one key at a time, and `config.get()` is
typed from it: a key path the schema covers resolves to that key's validated,
deep-frozen value with a real type, and everything else reads straight from nconf
with the `any` it has always had. Call sites do not move. A key gains validation,
freezing and a type at every existing `config.get('that:key')` in the same change
that adds its schema, so there is no half-migrated state to reason about and no
codemod to land.
Only `url` and `env` are schemafied here. Both are deliberately no stricter than
what the loader already asserted, so this validates nothing new.
Two details worth knowing about the typing. `z.looseObject` adds an index
signature, which collapses the key-path union to `string` and silently types
everything as `any` unless it is stripped at each level - hence `Known<T>` in
schema.ts. And the path union stays cheap: a synthetic 90-key schema three levels
deep produces 2969 paths and adds 0.23s to a cold `tsc --noEmit` over ghost/core.
Writing through nconf drops the validated view rather than rebuilding it, because
`configUtils.restore()` writes one key at a time and re-validating part-way
through would reject a config that is only briefly incomplete. Production never
calls `set`, so this costs nothing there.
Production only warns on a schema violation. Ghost(Pro) injects config through
environment variables this repo cannot see, so a schema this repo got subtly
wrong should be a log line rather than a fleet-wide boot crash-loop. Development
and test boot strictly, and GHOST_CONFIG_SCHEMA_STRICT overrides either way.

no ref The schema already validated config, but only the key paths it named were served from the validated result - everything else still read nconf's live stores. Two representations, kept in sync by invalidating one whenever the other was written. That split is what blocked the two things this is for. Freezing only covered the schemafied part, so the config a caller could still mutate was most of it. And a transform could never be safe: a transformed parent and a raw read of an unlisted path beneath it would disagree, because they came from different places. nconf's job now ends at layering the sources. loadNconf() hands its merged tree to createConfig(), which validates it once, deep-freezes it, and returns the object everything reads from then on. The whole config is immutable, not only the typed part, because the schema is loose: a key it does not name is still validated and frozen, just typed `any`. Call sites are unchanged - `get()` walks the frozen tree instead of merging nine stores. set() and reset() stay for tests, and both now rebuild the whole tree from the loaded sources plus the overrides recorded so far. That had to change: nconf's reset() empties every store and configUtils.restore() reapplies 117 keys one at a time, so for the length of a restore the config did not validate - 61 top-level keys, all of them environment variables, no `url` and no `env`. Validation is atomic, so the rebuild has to be too. configUtils needs no changes at all now. writePath copies a level on the way down if it is frozen, because an override's value is often something a test read back out of config. One test was doing read-modify-write on a config object and now sets the path directly. Nothing else in the tree needed changing: the two places that wrote through into config are fixed in the preceding commits. Verified: unit 9320, integration 483, e2e 2661 (one known cross-test flake in the actions audit log, clean in isolation). A development boot is clean - no read-only errors - and all four shipped environments validate under GHOST_CONFIG_SCHEMA_STRICT=true and come back frozen.
no ref
MigratorConfig.js hands `config.get('database')` straight to knex-migrator, and
its connect() assembles knex's options by mutating what it is given: it sets
connection.timezone, charset and decimalNumbers, and deletes connection.filename.
On main that write succeeds, and leaks into config like the two cases fixed in
the preceding commits. Once config is read-only it stops succeeding - and
knex-migrator is sloppy-mode CommonJS, so it does not throw either. The write is
simply dropped, and the migrator's connection silently loses its timezone,
charset and decimalNumbers.
It now gets a clone. cloneDeep rather than structuredClone: this hands a tree to
a third party we do not control, so it must not throw on a value it cannot
clone - and structuredClone does throw on a Proxy, which rules it out for the
read-only guard described below.
Found by temporarily replacing the deep freeze with a Proxy whose set trap
throws, then running the unit, integration and e2e suites against both MySQL and
SQLite plus a development boot. Deep-freezing could not have found it: Ghost's
production .js files and its dependencies are sloppy-mode CommonJS, where a write
to a frozen object is dropped without an error. That guard is worth having under
test as its own change; this was the only violation it found.
no ref The obvious reading of schema.ts is that every key should end up in it. Following that would make shared/config - the bottom of the dependency graph, which knows nothing about any feature today - describe bulkEmail, tinybird, machinePayments and the rest. The lowest-level module in the tree would gain inbound knowledge of the highest-level features. The split that avoids it: keys boot cannot start without stay central and fail at load; everything else is the feature's concern, parsed by the feature when it initialises. That needs nothing new - the tree is loose and frozen, and parsing a frozen subtree returns a fresh unfrozen object, so a feature can validate its own slice next to the code that reads it today. It is also the better place for it, since a feature-scoped schema can use strict objects, defaults and coercion that would be reckless centrally, and a broken Mailgun config should not stop Ghost serving pages. Also records the two alternatives that were considered and rejected, so they are not re-proposed: self-registration at import time cannot work when config is the first thing loaded, and generating schema.ts from per-feature schemas buys load-time failure for config that should not fail boot. Corrects two things while here. The `node --use-strict` note was wrong - the flag makes only the entry point strict, and a required CommonJS module keeps its own strictness, so it cannot enforce the freeze at all. And the list of places that wrote through into config was missing knex-migrator, which is the instructive one: when a dependency assembles its own options from what you hand it, it needs a copy.
no ref z.toJSONSchema() carries .meta() descriptions and examples straight through, so the schema can generate a config reference for self-hosters later. That only works if the metadata is there, and writing it with the key costs a line while retrofitting it across every key is a sweep nobody will volunteer for. So it is now a step in the SCHEMA.md instructions, and the two keys that have schemas today carry their own descriptions rather than telling the next person to do something the existing examples do not. .meta() registers in zod's registry and does not affect parsing, so the round-trip test over the shipped env configs is unchanged.

…31330) no ref Config is deep-frozen after validation, which makes it immutable but not loud. Ghost's `.js` files and its CommonJS dependencies are sloppy-mode - 1324 of the 1330 `.js` files under `core/` carry no `'use strict'` - and a write to a frozen object there is dropped without an error. `node --use-strict` does not help: it makes only the entry point strict, and a `require()`d CommonJS module keeps its own strictness. So each of the three write-throughs fixed in #31326 and #30936 was silent, and the next one would be too. guard.ts swaps the freeze for a proxy whose `set`, `defineProperty`, `deleteProperty` and `setPrototypeOf` traps throw, naming the key path. A trap fires whatever mode the caller is in, so a write that production would merely lose fails a developer's boot or CI instead: TypeError: Ghost config is read-only: attempted write to `paths:contentPath`. It is on in `development` and `test*`, matching the environments that already validate strictly, and `GHOST_CONFIG_GUARD` overrides either way. Production keeps the frozen object. The two cannot be combined: a proxy over a deep-frozen target may not return a wrapped child, because the invariant for non-writable, non-configurable properties forbids handing back anything other than the target's own value - so a guarded tree is deliberately left unfrozen and relies on the traps instead. Freezing is also the cheaper read: on a microbenchmark a scalar read goes from 4.5ns to 21ns and a spread of a config object from 120ns to 2.4µs. That is immaterial to the test suite, but not worth paying on every request to catch a class of bug CI now catches first. Three details that are easy to get wrong: - The `getOwnPropertyDescriptor` trap is required. Without it, `Object.getOwnPropertyDescriptor(guarded, k).value` hands back the raw child and a write through it misses every trap. Wrapping the descriptor's value is only legal because a guarded tree is left unfrozen. - Children are wrapped lazily from the get trap and memoised in a WeakMap per underlying object, so only what is read pays for it, `===` stays stable across reads of the same subtree, and cycles terminate. - Symbols and functions pass through unwrapped - symbols carry iterators and inspection hooks, and the functions are array and object methods. Class instances are left alone for the same reason: wrapping something with internal slots breaks it. writePath() now copies every level it traverses rather than only frozen ones. Copy-on-write was keyed on `Object.isFrozen`, which is never true under the guard, so a nested override wrote in place into an object an earlier `get()` had handed out: `set('paths', {contentPath: '/first'})` followed by `set('paths:contentPath', '/second')` retroactively changed the first result. Guarded and unguarded config have to answer identically - the guard exists to make a write loud, not to change what config does. Cloning override values on each rebuild would fix it too, but every `set()` replays every override, which would make configUtils.restore's 117 keys quadratic in deep clones. A sloppy-mode fixture covers the premise directly: it writes to frozen config from a module with no directive and asserts the write is silently dropped, so the reason the guard exists stays tested rather than only described in SCHEMA.md. Verified on a Pro staging boot with `GHOST_CONFIG_GUARD=true` - the only way to exercise the Pro image's own code, and the Redis-cluster and Pro-adapter paths CI never constructs. Nothing threw.

Makes Ghost's config immutable and validated, and types
config.get()from the schema — without moving a single call site.Builds on #31326 (merged), which fixed two places that wrote through into config. This change needs those: once config is frozen, both become silent breakage.
Supersedes #30722.
Why
Config is loaded by nconf and read through
config.get('a:b'). That returnsany, hands out a live reference into nconf's stores, and for an object-valued key deep-merges a hit from each of nine stores on every call.How
nconf's job ends at layering the sources.
loadNconf()hands its merged tree tocreateConfig(), which validates it against a zod schema, deep-freezes it, and returns the object everything reads from then on. Nothing reads nconf again after load.One representation, so the whole config is immutable — not only the part a schema names. The schema is loose, so a key it doesn't list is still validated and frozen, just typed
any.A schema adds a type.
config.get()is typed from it, so a covered key path returns that key's type at every existing call site. No codemod, no half-migrated state:Only
urlandenvare schemafied here, both no stricter than assertions the loader already ran. This change installs the mechanism; it validates nothing new.Reads get much cheaper, since a path walk replaces a nine-store merge:
get('database')get('database:client')get('url')get('database').connection.filename{...get('database')}Retaining the tree costs 34 KiB (117 top-level keys, 59 of them environment variables). #30722 avoided caching the merged tree on the grounds that it would hold every environment variable; measured, that isn't a reason.
Measured on a Pro-like config
Benchmarked against a matched
mainbaseline on the Pro image (5000 requests, dedicated runner). Sanity first, since the numbers are meaningless without it: calibration 364 vs 370 ms (this branch's host 1.6% slower), steal 0.006% / 0.009% — both far under the 1% contamination threshold.The finding that does not depend on run-to-run noise is attribution.
nconfis in the baseline CPU profile at 1834 ms self time, 1.7% of busy time, and is absent entirely from this branch's profile — its nine-store merge no longer runs on request paths:load.cpu_sagrees directionally at 104.6 → 102.7 (−1.78%), on the slower host — but that is one run per side, and per-endpoint p99s swing ±15–22% in both directions, so treat it as directional only.Boot is unchanged.
boot.cpu_sreads +6.55% from a single sample, but boot wall over 5 runs is faster here (2480 vs 2518 ms mean, within ±75–93 ms stddev), and the obvious suspect is ruled out — zod was already loaded at boot onmain(identical 95 files;main's RSS is in fact 3 MB higher).load.heap_used_bytes−59% is GC sampling, not a result.Notes for review
set()/reset()are test-only, and now rebuild atomically from the loaded sources plus the overrides recorded so far. This had to change: nconf'sreset()empties every store andconfigUtils.restore()reapplies 117 keys one at a time, so for the length of a restore the config did not validate — 61 top-level keys, all environment variables, nourland noenv. Validation is atomic, so the rebuild must be.test/utils/config-utils.jsneeded no changes.writePathcopies a level on the way down if it's frozen, because an override's value is often something a test read back out of config.z.looseObjectadds an index signature, which collapses the key-path union tostringand silently types everythingany.OmitIndexSignaturestrips it at each level. Worth knowing before adding a nested section.tsc --noEmitover ghost/core.nconf.env()runs with no whitelist, so every process environment variable is a top-level config key —config.get('PATH')resolves today. Closing the schema needs that whitelisted first, in its own change.developmentandtest*throw on a violation;production, and whatever NODE_ENV a self-hoster picks, log and carry on.

settrap throws, then running the unit, integration and e2e suites against both MySQL and SQLite, plus a development boot. It was the only violation anywhere:On enforcement
A runtime guard can't carry this; the compiler has to. Ghost's
.jsfiles are sloppy-mode CommonJS, where writing to a frozen object is silently dropped rather than thrown.node --use-strictdoes not fix that, contrary to what an earlier version of this description claimed. It makes only the entry point strict — arequire()d CommonJS module keeps its own strictness, with or without tsx:So a suite run under the flag proves nothing about the modules under test. The options that would actually enforce the freeze are
'use strict'directives across the 1330 production.jsfiles (6 have one today), or the Proxy guard above gated to the test environment, since a trap throws regardless of the caller's strictness. The guard is the cheaper one and would have caught all three write-through sites. Worth doing as its own change, not this one.Testing
