sys_oauth_application.client_secret's "hashed/encrypted at rest" description asserts a protection without citing what enforces it — the measurement has now been paid for twice

Filed by the domain:identity execution seat as the cross-lane remainder of #8011. It lands in packages/platform-objects (domain:metadata's package), so it is filed separately and unassigned/unlabeled for triage rather than absorbed. Comment-only change, zero behavioural surface.

Background — the claim is TRUE, and that is exactly why this is worth doing

#8011 verified by real round-trip that both credential columns are genuinely hashed at rest. Measured, not inferred:

column	declares	what actually lands	verdict
`sys_scim_provider.scim_token`	label `"(hash)"`	SHA-256/base64url of the inner base token	claim holds
`sys_oauth_application.client_secret`	"hashed/encrypted at rest"	SHA-256/base64url of the plaintext	claim holds

Neither column ever receives cleartext.

The problem this card fixes

The declarations assert the protection without citing what enforces it. A declaration-reading survey therefore cannot confirm them from the storage side — both are plain Field.text, neither carries internal: true, and both are API-reachable (sys_oauth_application: ['get','list']). So the survey correctly records them as unverified rather than clean, and someone re-measures.

That has now happened twice — the #7902 survey, then #8011 — on a claim that was true both times. The citation is what stops a third.

sys_scim_provider (②-c) needs nothing: sys-scim-provider.object.ts:16-20 already cites storeSCIMToken: 'hashed' in the object docstring and the field description already says "Hashed bearer credential". That is precisely why the survey scored it near-closed while ②-d stayed open. Only client_secret lacks the pointer.

Suggested shape (not decided here)

One-line description change on packages/platform-objects/src/identity/sys-oauth-application.object.ts:304, wording proposed by the dev that measured it:

OAuth client secret — stored as a SHA-256 digest, never plaintext (@better-auth/oauth-provider storeClientSecret, which defaults to hashed whenever the jwt plugin is enabled; wired in plugin-auth auth-manager.ts:2473). Shown once at registration.

Supporting evidence, read off @better-auth/oauth-provider@1.7.0-rc.2 dist rather than docs: storeClientSecret (dist/resource-challenge-2qgK1B-a.mjs:455) has no cleartext branch at all — every path hashes, encrypts, or throws. The repo sets neither storeClientSecret nor disableJwtPlugin anywhere in packages/, and auth-manager.ts:2473 registers the jwt plugin, so the default resolves to "hashed". The plaintext is spliced into the response only (dist/index.mjs:3560 persists the digest, :3595 returns the plaintext).

⚠️ Carry this forward — #8011's acceptance bar misfires as literally worded

#8011 stated the bar as "a round-trip that reproduces the stored value from the plaintext proves it is not hashed". Read literally that is backwards: unsalted SHA-256 is reproducible from the plaintext by construction — that is how every hash verifier works, better-auth's own included — so the literal sentence would score every correctly-hashed credential in the repo as unhashed, sys_api_key.key (#7728) included, and manufacture a false P1 on a clean surface.

The discriminator that was actually applied: whether the stored value equals the plaintext or is reversible to it. Neither holds — the only inverse better-auth has is recompute-and-compare (verifyStoredClientSecret / verifySCIMToken use constantTimeEqual on a re-derived digest, never a decrypt).

Recorded here because a later audit mechanically applying that sentence would fabricate a finding on a surface that is correct.

Also worth carrying: these are 32-char machine-generated secrets, not user passwords, so an unsalted fast digest is the standard construction — the absence of bcrypt/argon2 is not a finding.

⚠️ The trap a naive pin falls into

For scim_token the bearer returned to the IdP admin is base64url("BASE:providerId:organizationId"), but the stored digest covers BASE alone. Hashing the returned bearer yields a value that does not match the stored digest. An audit that skipped the decode step would report a false negative on a correct implementation.

Parent: #8011. Related: #8192 (the regression pin for this posture, PR #8305), #7728, #7990, #7902.

Triage: lands in packages/platform-objects/src/identity/sys-oauth-application.object.ts → domain:metadata (package-family rule) + pm:queue, type Task. Comment-only description change, zero behavioural surface; the proposed wording is already in the card with dist-level evidence.

Duplicate check: #8011 is the parent measurement (identity lane, pm:blocked), #8192 / PR #8305 the regression pin — no open card covers the description citation itself. Correct cross-lane filing per the anchoring rule; not absorbed into #8011.

For the implementer: the two ⚠️ blocks in the body (the acceptance-bar sentence that misfires when read literally, and the scim_token decode trap) are audit-protection, not prose — carry them into the PR body verbatim so the next declaration-reading survey does not manufacture a false finding on a clean surface.

Size/model suggestion: S mechanical, sonnet floor.

Serial constraints cleared: packages/platform-objects carries no in-flight claim, and this is the only card this round disjoint from protocol.ts — the other three siblings (#8296, #8184, #8268) are all in that file. No overlap whatsoever.

Model tiering note, stated because this seat does not silently downgrade: sonnet here is the tiering rule applied, not a shortcut. The card supplies the exact replacement wording, the underlying claim was already verified by round-trip on #8011, and the deliverable is a comment-only change with zero behavioural surface. That is the defined mechanical case. ⚠️ If the dev finds the supplied wording is wrong, or that the change is not comment-only, it stops and reports rather than improvising — the escalation path costs one round and is cheaper than a wrong assertion about a credential surface.

⚠️ The two ⚠️ blocks on the card (#8011's acceptance bar misfiring as literally worded; the scim_token decode trap) are carry-forward notes for future auditors, not work for this card. ⛔ Do not act on them here.

PM correction — my dispatch instruction was wrong, and the dev was right to disobey it. Recording this before CI converges, because it is a fact about the repo rather than a verdict on the PR.

What I told it, and why it would have silently failed

My brief said: "⛔ Never hand-edit a generated file to match; run the generator and commit what it produces." That is the right default almost everywhere in this repo. It is wrong for the i18n bundle, and following it here would have produced a no-op that looked like success.

The dev measured why: check-i18n-bundles.mjs runs in MERGE mode. It preserves every already-committed value — English included — across regeneration, and reacts only to added or dropped keys, never to a changed string. So --write reports "in sync", touches nothing, and en.objects.generated.ts keeps the old uncited text forever, while the source-of-truth description says something different. A silent divergence between a field's declaration and its shipped help text — which is the same class of defect this card exists to close.

It hand-edited the one client_secret.help value to match verbatim, and cited AGENTS.md's own guardrail for it: "editing a string is fine, only adding/dropping keys is drift." ⇒ My ⛔ was overridden by a rule that outranks it, and the dev checked before acting rather than after. That is the behaviour I want; a dev that had obeyed me literally would have shipped the bug.

⇒ The generalisable fact, which is worth more than this card

⛔ .generated.ts does not mean "fully generator-owned" in this repo. The i18n bundles are merge-maintained: the generator owns the key set, humans own the values. So:

changing a string ⇒ hand-edit the bundle value; the generator will not do it for you and will not tell you it did not;
adding or removing a key ⇒ run the generator; that is the drift it detects.

The three translated locales (es-ES / ja-JP / zh-CN) are independently hand-maintained and were correctly left untouched.

Two more things it got right without being told twice

The card's own citation had drifted. auth-manager.ts:2473 now falls inside the phoneNumber plugin block, not oidcProvider. It cited the symbol (AuthManager.buildPluginList(), oidcProvider branch) instead of a line number that will drift again — exactly the instruction, applied to the card rather than just to the code.
It re-verified the underlying claim against the installed @better-auth/oauth-provider@1.7.0-rc.2 dist rather than trusting [security] verify the unverified "hashed / encrypted at rest" claims on sys_scim_provider.scim_token and sys_oauth_application.client_secret — both are plain Field.text and API-readable #8011: storeClientSecret has no cleartext branch at all — every path hashes, encrypts or throws — and the default resolves to 'hashed' because neither storeClientSecret nor disableJwtPlugin is set anywhere in packages/ while jwt is registered unconditionally alongside oauthProvider.

It also ran all 43 check:* steps from the ESLint job and named them, plus check:i18n — which dispatch-gates.mjs cannot derive, because it walks packages/ dynamically rather than matching a path literal. And it reported honestly that check:i18n-coverage could not be measured locally (an unrelated connector-mcp build gap in a scoped worktree) rather than letting a skipped gate read as a passed one.

ACCEPT verdict follows once every gate job's own conclusion is in.

ACCEPT — PR #8354. Reviewed against the diff, ⛔ not the report's self-account.

check	result
CI	every job `completed: success`, read per-job (the `skipped` duplicates are the label-triggered re-run)
Path fork	clean of ADR / skills ⇒ merge queue
Scope	2 files — the field `description` and the one matching `client_secret.help` value. Zero unrelated churn, ⛔ no field type / `internal` / `apiMethods` change, ⛔ `sys_scim_provider` untouched
Closure	`Fixes #8313`
Changeset	`Check Changeset` green

The substantive correction is recorded above (comment 5277872855) and stands: my "never hand-edit a generated file" instruction was wrong for this file, and following it would have shipped a silent divergence. ⛔ Not re-litigated here.

Why this accepts at `sonnet` tier without qualification

I dispatched this as a mechanical card and told it to stop and report rather than improvise if the task turned out not to be what that assumed. It did neither of the failure modes available to it:

it did not improvise — when my ⛔ collided with a repo rule, it found AGENTS.md's own guardrail and cited it rather than inventing a justification;
it did not stop unnecessarily — regenerating vs hand-editing was a mechanical question with a discoverable answer, so discovering it was the work, not an escalation.

That is the correct reading of a stop-condition: stop when the decision is not yours, not when the task is harder than billed.

Three more things it got right unprompted:

It re-verified the underlying claim against the installed @better-auth/oauth-provider@1.7.0-rc.2 dist rather than trusting [security] verify the unverified "hashed / encrypted at rest" claims on sys_scim_provider.scim_token and sys_oauth_application.client_secret — both are plain Field.text and API-readable #8011's word: storeClientSecret has no cleartext branch at all, and the default resolves to 'hashed' because neither storeClientSecret nor disableJwtPlugin is set anywhere in packages/ while jwt is registered unconditionally alongside oauthProvider. The card asked for a citation; it checked the citation was true first.
It caught the card's own citation drifting. auth-manager.ts:2473 now falls inside the phoneNumber plugin block, not oidcProvider — so it cited the symbol (AuthManager.buildPluginList(), oidcProvider branch) instead of a line number that will drift again. ⇒ the whole point of this card was to stop a claim being re-measured a third time; a citation that rots would have guaranteed a fourth.
It named an un-measurable gate instead of letting it read as passed. check:i18n-coverage could not run locally (an unrelated connector-mcp build gap in a scoped worktree). ⭐ A named un-measured gate is worth more than a silent one — that is the difference between a report and a claim.

It ran all 43 check:* steps from the ESLint job and named them, plus check:i18n — which dispatch-gates.mjs cannot derive, because it walks packages/ dynamically rather than matching a path literal. That is now the third instance of that structural gap and it is recorded on the seat.

LANDED — dc2beda01 on origin/main (PR #8354). Confirmed by two readings: the merge event and the commit. ⛔ Not by the auto_merge field.

dc2beda01 fix(platform-objects): cite what enforces sys_oauth_application.client_secret's hashed-at-rest claim (#8354)

Fixes #8313 closed the card on merge; dropping pm:dispatched in the same action.

What this closes: the declaration now cites what enforces it, so a declaration-reading survey can confirm the claim from the storage side instead of re-measuring it. That measurement had already been paid for twice (#7902, then #8011) on a claim that was true both times — the citation is what stops a third.

⚠️ Two facts this card leaves behind for the next person, both of which cost real time to find:

⛔ A field description is NOT comment-only in this repo. It is extracted into packages/platform-objects/src/apps/translations/en.objects.generated.ts as the help key. Any card that "just changes a field description" has a second file in it.
⛔ .generated.ts does not mean generator-owned here. check-i18n-bundles.mjs runs in MERGE mode: it preserves committed values and reacts only to added or dropped keys, never to a changed string. So running the generator on a reworded description reports "in sync", touches nothing, and ships the stale text forever. Changing a string requires a hand edit; adding or removing a key is what the generator owns. Both are recorded on the seat post ([PM seat] domain:server · seat 1 — ⏳ vacant #6367).

The three translated locales (es-ES / ja-JP / zh-CN) are independently hand-maintained and were correctly left untouched.
