[objectql] TRUE readonlyWhen strips beforeUpdate-derived values too — a conditionally-locked derived field has no server-side write path at all (isSystem included), unlike static readonly's hook-stamp protection

Summary

On the by-id UPDATE path, stripReadonlyWhenFields runs after the beforeUpdate hooks, is keyed on name in data over the post-hook payload, and is not gated on opCtx.context?.isSystem. The static readonly strip immediately below it has both protections: it is skipped entirely for isSystem callers, and its suppliedValues discipline drops only caller-forged writes — the code comment states the intent verbatim: "suppliedValues ensures only caller-forged read-only writes are dropped, never the server stamps — and (#5591) never a stamp a hook wrote OVER a key the caller happened to echo back."

Consequence: a field locked by a TRUE readonlyWhen predicate has no write path at all for server-derived values. A beforeUpdate hook computes it — stripped. A cron/plugin writes it with { context: { isSystem: true } } — stripped. The engine's own strict-mode refusal text documents the behavior ("this exempts statically 'readonly' fields, but NOT fields locked by a TRUE 'readonlyWhen' predicate — those stay locked for every caller"), so the "every caller" half may well be deliberate — but it never got the derived-write story static readonly got: the strip that exists to stop caller forgeries also silently discards server-authored stamps, and no sanctioned alternative channel exists.

Net effect: the derived-field pattern (hook-computed column) and conditional readonly cannot coexist on one field. An author who wants "visible on the form but locked" (which hidden cannot give, and static readonly historically did not render at all in that project's form) plus "recomputed by a hook" has no spec-compliant spelling.

Where (origin/main @ `bb3def4`)

packages/objectql/src/engine.ts L9528: stripReadonlyWhenFields(...) — unconditional, runs on hookContext.input.data after the before-phase hooks (ADR-0058 Addendum II ordering).
packages/objectql/src/engine.ts L9556: stripReadonlyFields(...) — inside if (!opCtx.context?.isSystem), with suppliedValues, so hook stamps survive (update 路径的 stripReadonlyFields 删除的是 hook 已覆写的当前值而非调用方提交的值 —— 调用方回传 readonly 键会连坐抹掉 beforeUpdate hook 的写入,可落出 status=published 而 published_at=null 的行(17.0.0-rc.2) #5591 comment directly above).
packages/objectql/src/validation/rule-validator.ts stripReadonlyWhenFields: if (!def?.readonlyWhen || !(name in data)) continue; — data is the post-hook payload, so a key a hook added is judged exactly like a key the caller sent.
packages/objectql/src/readonly-strict-errors.ts: the strict-mode refusal text quoted above.

The multi-row branch (L9697/L9710) has the same shape.

Minimal repro

Standalone — one object, one hook, no app dependency:

// demo.object.ts — a derived date that must stay form-visible but user-locked
fields: {
  period_days: { type: 'number' },
  next_date:   { type: 'date', readonlyWhen: P`true` },
}

// demo hook
beforeUpdate: (ctx) => {
  // derive next_date from the payload / prior record
  ctx.input.data.next_date = addDays(today, ctx.input.data.period_days ?? 90);
}

// caller — system context, by-id update
await engine.update('demo', id, { period_days: 90 }, { context: { isSystem: true } });

Observed on @objectstack/objectql 17.0.0: period_days lands; the hook-computed next_date is stripped with reason readonly_when (visible via options.onFieldsDropped; with strictReadonlyWrites the refusal message is the one quoted above). The row keeps the stale value. Same outcome for a plain user-context PATCH, a plugin/cron write without context, and { context: { isSystem: true } } — there is no caller for which the hook's value persists.

Expected — one of (decision needed, ascending cost)

A. suppliedValues parity (recommended). Give stripReadonlyWhenFields the same key discipline update 路径的 stripReadonlyFields 删除的是 hook 已覆写的当前值而非调用方提交的值 —— 调用方回传 readonly 键会连坐抹掉 beforeUpdate hook 的写入,可落出 status=published 而 published_at=null 的行(17.0.0-rc.2) #5591 gave the static strip: judge only engine-entry caller-supplied keys, never keys a hook added or overwrote. The caller-facing lock is unchanged — a client cannot turn its own key into a "hook-written" one — and the mechanism and its rationale are already accepted in this file. "Locked for every caller" stays true at the API boundary; it stops being true only for the server's own trusted hooks, which is exactly the static-readonly status quo pinned in [objectql] readonly 字段:服务端插件 data.update 直写被静默剥离(200但值不变),与 beforeUpdate Hook 补写可落库不对称 #4903.
B. isSystem parity. Honor { context: { isSystem: true } } for readonlyWhen like static readonly. Weaker: it flips the documented "every caller" wording, and it lets any system-context write bypass a state lock (the paid-invoice-frozen-lines case Parent-scoped readonlyWhen is unenforced server-side — the field lock fails open, so a paid invoice's frozen lines can be rewritten over the API #4889 is built on) — probably not what a state lock means.
C. An official derived-field write channel. Keep the strip total and add sanctioned vocabulary (a field-level "derived by hook" declaration, or an engine option scoped narrower than isSystem). Cleanest contract, biggest surface.

If instead "total lock, hooks included" is confirmed as the intended contract, it should be (a) stated in the spec/docs for readonlyWhen — today only the strict-mode error text says it — and (b) lint-visible: an object whose own hook assigns a field that also declares a readonlyWhen that is TRUE in that state is authoring a write that can never land. That is a declared-vs-enforced gap a publish-time gate could reject loudly instead of letting it fail as a silent runtime strip.

Real-world impact (measured, downstream)

Part of steedos-labs/os-project-titanwind-ehr#1446. equipment.next_maintenance_date is hook-derived (last maintenance date + cycle days) and was declared with an always-true readonlyWhen to render visible-but-locked on the edit form. After a maintenance sign-off the recompute silently never landed (HTTP 200, field dropped), and a scheduler keyed on that date regenerated the same maintenance plan on every scan — a user-visible duplicate-plans loop, diagnosed only by reading the engine's strip order in the dist bundle.

The app shipped a metadata-level workaround (steedos-labs/os-project-titanwind-ehr#1451): the predicate became !has(record.maint_recalc) || record.maint_recalc != true, plus a hidden always-locked boolean token field the hook sets in the same payload — the token itself is always stripped (never persists), but the merged-snapshot evaluation (readonlyWhenBindings, { ...previous, ...data }) reads it within that one update, so the derived value survives. It stays inside declared platform semantics — no driver bypass, no node_modules patch — and the project is not blocked. But it is exactly the kind of clever in-band pattern AI-authored metadata will now copy everywhere a derived field needs a form lock. We would retire it for an official channel; recording that unblock condition here.

Versions

@objectstack/objectql 17.0.0 (npm latest at filing time). Behavior reproduced on 17.0.0 GA; strip ordering and gating verified unchanged on origin/main @ bb3def4.

Prior-art sweep before filing: #3042 / #3044 (multi-row enforcement), #4889 / #4972 (parent scope), #4953 / #6454 (total-record materialization), #4903 (static readonly vs plugin-write asymmetry — closed with the hook-stamp mechanism documented and the asymmetry pinned), #6437 (DroppedFieldsEvent.reason), #3425 (static readonly semantics formalized). None covers the hook-derived / isSystem gap for readonlyWhen.

Triage: needs-user-decision + domain:engine-core (packages/objectql write path) + type Feature. Human floor, not auto-adjudicable: every option changes contract accept behavior — the shipped strict-mode refusal text documents today's "stays locked for every caller" semantics, so options A and B both flip a documented behavior, and option C mints new declared vocabulary. External report with a named downstream customer (titanwind-ehr#1446) and a shipped in-band workaround (#1451), so the reporter is not blocked — this is a contract-shape question, not a p0.

Four-axis card face

Platform long-term coherence: A shrinks a special case — it gives stripReadonlyWhenFields the exact suppliedValues discipline the static strip already carries (update 路径的 stripReadonlyFields 删除的是 hook 已覆写的当前值而非调用方提交的值 —— 调用方回传 readonly 键会连坐抹掉 beforeUpdate hook 的写入,可落出 status=published 而 published_at=null 的行(17.0.0-rc.2) #5591), collapsing two strip mechanisms onto one accepted rationale. B weakens state locks generally (isSystem bypass on the paid-invoice-frozen class Parent-scoped readonlyWhen is unenforced server-side — the field lock fails open, so a paid invoice's frozen lines can be rewritten over the API #4889 is built on). C is the cleanest contract but the largest new surface.
Measured business pull: real and specific — a hook-derived, form-visible-but-locked field silently kept a stale value; a scheduler consuming it produced a user-visible duplicate-plans loop, diagnosed only by reading dist. The workaround pattern (predicate token + merged-snapshot read) is exactly what other AI-authored apps will now copy.
AI-agent error-resistance: today the failure is a silent strip behind an HTTP 200 — the worst shape. A removes the trap for the derived-field pattern. If instead "total lock, hooks included" is confirmed, the card's own fallback is the right floor: spec/docs statement + a publish-time author-rule that loudly rejects an object whose own hook writes a field its always-TRUE readonlyWhen will strip (declared-vs-enforced made visible at authoring time).
Startup scope discipline: A adds no declared surface and reuses an in-file mechanism; C declares a new permanent key; B is one conditional but flips documented wording. A is the cheapest honest move.

Recommendation: Option A (suppliedValues parity), plus doc wording that "every caller" means every API-boundary caller. All four prisms point the same way, but this is an accept-behavior change on the engine write path ⇒ maintainer's call, and if ruled, the model floor for contract-behavior changes applies (model: claude-fable-5).

Fork clause for the eventual implementer: if measurement shows any consumer depends on the strip discarding hook-written values (e.g. as a state-lock guarantee), stop and bring the measurement back — do not route around it.

Dedupe: prior-art sweep in the card body is accurate; no open card covers the hook-derived/readonlyWhen gap (checked against the full open set this round).

Triage: this comment comes from the triage seat Routine; not a claim.

Maintainer ruling (2026-08-17, recorded by PM session session_01NYgmGheCzM6NrHZN436Cxf). The maintainer reviewed the decision-inbox report's six new cards and accepted the recommendations in full, verbatim: 「新进卡六张同意你的建议」. For this card:

Ruled: Option A — suppliedValues parity for stripReadonlyWhenFields.

The conditional strip gains the exact key discipline update 路径的 stripReadonlyFields 删除的是 hook 已覆写的当前值而非调用方提交的值 —— 调用方回传 readonly 键会连坐抹掉 beforeUpdate hook 的写入,可落出 status=published 而 published_at=null 的行(17.0.0-rc.2) #5591 gave the static strip: only engine-entry caller-supplied keys are judged; keys a hook added or overwrote survive. The API-boundary lock is unchanged — a client cannot turn its own key into a "hook-written" one.
Both by-id and multi-row branches; docs/refusal wording updated so "stays locked for every caller" reads "every API-boundary caller".
Fork clause (binding): if measurement shows any consumer depends on the strip discarding hook-written values as a state-lock guarantee, stop and bring the measurement back.
model: claude-fable-5 mandatory — accept-behavior change on the engine write path.
Downstream note: once released, the titanwind-ehr workaround (predicate-token pattern) should be retired per that project's recorded unblock condition — the reporter can be pinged on release.

Label flipped needs-user-decision → pm:queue in the same stroke.

Claim — PM dispatch seat, session session_01Y26DJEHSBhhAQ6wwfsHNza, branch claude/issue-9107-readonlywhen-supplied-values.

Dispatching on the 03:19Z maintainer ruling: Option A — suppliedValues parity for stripReadonlyWhenFields, both by-id and multi-row branches, with the docs/refusal wording changed to "every API-boundary caller".

⚠️ Co-tenancy notice for the implementer — PR #9235 (issue #9228, another seat) is in flight and touches packages/objectql/src/engine.ts. Its hunks are in the filter-comparand compile path, not the update-strip region around L9528/L9697, so the surfaces look disjoint — but merge origin/main before finalising and re-check rather than trusting this note.

⛔ Binding fork clause, carried from the ruling: if measurement shows any consumer depends on the strip discarding hook-written values as a state-lock guarantee, stop and bring the measurement back. Do not route around it.

Generated by Claude Code

⛔ Dispatch aborted — blocked on the ruling's own model floor. Nothing was implemented; nothing was lost.

PM dispatch seat, session session_01Y26DJEHSBhhAQ6wwfsHNza. Following up my claim above.

The ruling makes model: claude-fable-5 mandatory ("accept-behavior change on the engine write path"). I dispatched on that model and the run terminated immediately on a Fable 5 usage limit, before the worktree existed. ⭐ No code was written, no branch was pushed, no partial state exists — unlike the #9106 incident, where the same limit killed a dev mid-verification and work had to be rescued off an ephemeral container.

Label moved pm:dispatched → pm:queue + pm:blocked. ⚠️ I am keeping the assignee deliberately: another seat picking this up would hit the same wall, and the block is not on the card's substance.

Why I am not just re-running it on `opus`

That is the obvious move and I am declining it on purpose. The model floor is a term of the maintainer's ruling, not a dispatch preference of mine, and the ruling gave a reason for it. Substituting a model to route around a binding term is the same shape as routing around a fork clause.

⚠️ There is a precedent, and I want it on the record accurately rather than leaned on: on #9106 the maintainer's operator authorised finishing on opus after the identical limit hit. But that was a rescue decision — ~90% of the work was done and pushed, and parking it would have thrown that away. Here the cost of waiting is zero. A rescue precedent does not generalise into a standing waiver, and I am not going to quietly treat it as one.

What unblocks this — either is fine, whichever comes first

Fable 5 quota recovers ⇒ I re-dispatch on the mandated model, no further ruling needed.
The maintainer waives the model floor for this card ⇒ say so on this thread and I dispatch on opus immediately.

Everything else on the card is ready: Option A is ruled, the scope is unambiguous, the fork clause is recorded, and the co-tenancy note about PR #9235 touching packages/objectql/src/engine.ts stands.

✅ Model floor WAIVED for this card — by the maintainer's operator, asked and answered

PM dispatch seat, session session_01Y26DJEHSBhhAQ6wwfsHNza. Recording the waiver explicitly so the ruling's written terms and what actually happened stay reconcilable — a ruling term that gets quietly not-followed is worse than one that gets openly amended.

What was asked: the ruling mandates claude-fable-5; that quota failed twice (07:22Z and 11:05Z, ~4 hours apart), both times before any work began. I put the choice up rather than deciding it: waive and run on opus, hold for the quota, or route it to the maintainer on this thread.

Answer: waive it — dispatch on opus now.

⚠️ Scope of the waiver, stated narrowly on purpose: it covers the model used to implement #9107, and nothing else. ⛔ It does not touch Option A's substance, the API-boundary lock, or the fork clause — all of which stand exactly as ruled. And it is not a standing waiver for other cards carrying model floors; the next one gets asked on its own facts, the same way this one was.

Label back to pm:dispatched. Re-dispatching now on opus, same brief.

⭐ Recorded for whoever reads this later: the earlier refusal to substitute unilaterally was not bureaucratic caution — it was that a quota being inconvenient is not evidence about whether the ruling's stated reason ("accept-behavior change on the engine write path") was correct. Those are different questions, and only the person who owns the ruling gets to answer the second one. What the two failures established was that "wait for it to clear" had no known end date, which is what made this worth asking rather than continuing to wait.

The premise was re-verified on current main (the card's bb3def43c254 is far behind) both structurally and empirically: the new pin file run against unmodified main failed 6 of 14 cases, every one a direction where a hook-derived value should have survived, while the 8 API-boundary-lock cases passed before and after. The API-boundary lock is unchanged and pinned in all three ruled directions, including the laundering case — a caller that echoes the locked key back is stripped as before, and if a hook overwrites it the value that persists is the hook's, so the caller's value never lands either way; isSystem is still deliberately not an exemption.

PM answer — A, and here is the notice. ⚠️ This change can silently unlock a field on a downstream deployment.

PM dispatch seat, session session_01Y26DJEHSBhhAQ6wwfsHNza. The implementer measured a downstream consequence that nobody asked it to look for, flagged it as the PM's call, and ⛔ correctly did not contact the downstream project itself. Taking A: the notice goes on this thread now, and again at release.

⚠️ For the titanwind-ehr reporter (#1446 / workaround #1451) — read this BEFORE retiring the workaround

Your workaround sets a hidden always-locked boolean token in the same payload, and its design relies on that token being stripped and never persisting. Under this change that assumption inverts:

the token is written by your beforeUpdate hook, so it is now a hook-derived value;
hook-derived values are exactly what this change stops stripping — so the token now persists;
your predicate !has(record.maint_recalc) || record.maint_recalc != true reads it from the merged snapshot;
⇒ a token that starts persisting can invert the lock on the NEXT update.

⛔ The failure is silent and state-dependent. Nothing errors. The field simply stops being locked on a subsequent write, on records that happen to carry a persisted token. That is worse than a loud break, which is why this is not waiting for the release ping.

⇒ Before retiring the workaround, check whether the token is still needed at all — the underlying defect it works around is what this PR fixes — and if you keep any part of it, re-derive the predicate against a snapshot where the token can be present.

Why not B (fold it into the release ping)

The changeset does say "if an app relied on the strip discarding a hook's own write to a locked field, that write now lands." ⚠️ That sentence is true and would not have been enough. Nothing connects it to their specific token, and a reader who built the workaround on the opposite assumption will read that line as describing someone else's app. The whole point of a downstream notice is that the reader cannot be expected to re-derive the consequence for their own code from a general statement.

⇒ The release ping still happens as the ruling says. This is in addition, not instead.

On the delivery

⭐ The fork clause was measured three independent ways rather than waved at, which is what I most wanted here since it was the one thing that could have stopped this card:

a repo-wide sweep found exactly two real readonlyWhen declarations, and no hook writes either;
the pre-fix full objectql suite on unmodified main was green apart from the 6 intentionally-red new cases — so no existing test asserts that a hook-written locked value is discarded;
a downstream consumer sweep, all green.

Any one of those alone would have been an argument. Together they are a measurement, and they are what let the card land rather than bounce back for a ruling.

Also worth recording: check:type-check-debt caught a real defect in the dev's own diff (objectql TEST_DEBT 355 → 356 — the new pin file called registry.registerObject() without its required packageId). It fixed the source and left the ledger flat rather than raising the ratchet to absorb its own mistake. ⭐ That is the ratchet working exactly as designed, on the person who added it.

And the reverse verification pinned the right thing: 6 of 14 cases red against unmodified main, every one a direction where a hook-derived value should have survived, while the 8 API-boundary-lock cases passed before and after — including the laundering case. The lock did not move; only the hook path did.
