…ear retention floor Rule 8 covered only the erasure duty (8(1)) and Third Schedule thresholds; it was missing the 48-hour pre-erasure notice (8(2)) and the one-year retention floor on all processing, including via Data Processors (8(3)), verified verbatim against the Gazette No. 760 PDF. Adds both as obligations + law-vs-code callouts in 08-dpdp-and-privacy.md (with the two official Gazette illustrations quoted and a GDPR Art 17 collision noted as an open design constraint), a Rule 8(3) caveat on the tombstone-scrub section in 02-deletion-policy.md, corrects the now-stale "14 May 2027 off-by-one" bullet in 06-cross-cutting-integrations.md (lib/compliance/dpdp.ts already reads 13 May 2027), and adds the Gazette PDF to 14-references.md. No commencement dates changed — Rule 8(2)/(3) commence with the rest of Rule 8 on 13 May 2027. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Rule 8 obligations and references docs/compliance/08-dpdp-and-privacy.md, docs/compliance/14-references.md |
The documents describe 48-hour pre-erasure notices, one-year retention, processor obligations, GDPR conflicts, implementation gaps, and the official Gazette source. |
Enterprise policy integration docs/enterprise/40-compliance-and-data/02-deletion-policy.md, docs/enterprise/40-compliance-and-data/06-cross-cutting-integrations.md |
The deletion policy records Rule 8(3) retention limits and processor gaps. The integration note records the corrected 13 May 2027 date and the remaining breach-notification modeling gap. |
Estimated code review effort: 1 (Trivial) | ~5 minutes
Merge Risk: 🟡 Moderate · up to 6af9b
The documentation adds DPDP retention guidance, but its GDPR interaction statement may overstate when Indian law satisfies the Article 17(3)(b) exception, and its retention wording could misdirect implementation toward consent-artifact cleanup. Merge should wait for the cross-border wording to be corrected or explicitly accepted by privacy counsel.
Poem
A rabbit checked the Gazette bright
And marked the rules in careful light
Forty-eight hours before erasure
One year held logs for measured duration
Processors joined the paper trail
Clearer notes now guide the trail

| > 🟡 **Law-vs-code — 48-hour pre-erasure notice (Rule 8(2)).** DPDP Rules 2025 Rule 8(2) requires that, at least forty-eight hours before a Third Schedule erasure period completes, the Data Fiduciary inform the Data Principal that her personal data will be erased on completion of that period unless she logs into her user account, otherwise initiates contact with the Data Fiduciary for the specified purpose, or exercises a right in relation to that processing. There is no code today that computes a Third Schedule erasure date and fires a warning 48 hours ahead of it — the platform doesn't operate in any of the three Third Schedule classes (see the "What does *not* apply to us" note in [`docs/enterprise/40-compliance-and-data/02-deletion-policy.md`](../enterprise/40-compliance-and-data/02-deletion-policy.md)), so Rule 8(1)/(2) don't bind us today, but the notice mechanism has no implementation to fall back on if that ever changes. Rule 8(2) commences with the rest of Rule 8 in Phase 3 on **13 May 2027** — this does not move the phasing table above, it just confirms Rule 8(2) sits in the same phase as Rule 8(1). *(Source: DPDP Rules 2025 Rule 8(2); verified against the Gazette PDF 2026-08-27.)* | ||
| > | ||
| > 🟡 **Law-vs-code — one-year retention floor (Rule 8(3)).** Rule 8(3) opens "Without prejudice to sub-rules (1) and (2)," so unlike Rule 8(1)/(2) it binds independently of Third Schedule class membership: the Data Fiduciary must retain personal data, associated traffic data, and other processing logs — its own and any Data Processor's — for a minimum of one year from the date of processing, for the Seventh Schedule purposes, before causing erasure, unless another law requires longer retention or the Government notifies otherwise. The Seventh Schedule (`[See rule 23(1) and 8(3)]`) is a table of State-access purposes, not a general business-retention list: (1) State/instrumentality use of personal data in the interest of sovereignty/integrity of India or security of the State, (2) State use for performing a function or a law-mandated disclosure under any law in force in India, and (3) MeitY's assessment for SDF designation — each with its own named authorised person. So the floor exists to keep data obtainable for those State-access purposes for a year; it isn't conditioned on our purpose for processing, and it extends to our Data Processors, but we have no code that enforces it: the retention logic in `jobs/compliance/consent-retention-sweeper.ts` and in [`docs/enterprise/40-compliance-and-data/02-deletion-policy.md`](../enterprise/40-compliance-and-data/02-deletion-policy.md) only reasons about retention as an *upper* bound (the 5-7 year tax/accounting keep on money rows). No code change made — flagged for the live-impl PR. Rule 8(3) commences with the rest of Rule 8 in Phase 3 on **13 May 2027**. *(Source: DPDP Rules 2025 Rule 8(3) + Seventh Schedule; verified against the Gazette PDF 2026-08-27.)* |

Separate consent-artifact retention from financial-record retention.
Line 45 groups jobs/compliance/consent-retention-sweeper.ts with the deletion policy under the 5–7 year financial-record bound. However, docs/enterprise/40-compliance-and-data/02-deletion-policy.md states that the sweeper purges ConsentArtifact rows using auditRetainedUntil; financial rows follow a separate retention path. Clarify this sentence so Rule 8(3) implementation work is not routed to the consent-artifact sweeper.

| > ⚠️ **Design constraint, not yet solved — Rule 8(3) vs GDPR Article 17.** This is an ordinary legal-obligation conflict, not a novel deadlock: GDPR Article 17(3)(b) already exempts erasure where processing is necessary "for compliance with a legal obligation which requires processing by Union or Member State law" — but that clause names *Union or Member State* law specifically, so an Indian Rule 8(3) duty doesn't automatically qualify for an EU data subject's row. A user who is simultaneously a DPDP data principal and a GDPR data subject — e.g. an EU-resident consultee — can therefore face a genuine conflict on the same row: Rule 8(3) requires holding it a year for the Seventh Schedule's State-access purposes, while Article 17 requires erasing it "without undue delay" once invoked, with no Article 17(3)(b) shelter available. A single global retention constant can't resolve this; the fix is a per-jurisdiction retention policy evaluated at the row level. Recorded here as an open design constraint for whichever team builds cross-border retention — not implemented, and no code today distinguishes DPDP-governed rows from GDPR-governed rows for retention purposes. |

If Article 3(2) applies, Article 17 requires erasure only when an Article 17(1) ground is met and remains subject to Article 17(3), including legal-claims exceptions. Indian Rule 8(3) does not, by itself, establish the Article 17(3)(b) legal-obligation exception. Confirm the final cross-border wording with privacy counsel.

…ook again (#1303) * feat(stream): freeze a dormant pair's DM, and unfreeze it when they book again The last piece of #1270's scope. Nothing has ever ended a direct-message channel: `syncUserEventChannels` reconciles membership but no stage freezes or deletes a DM, so channel count and membership grow without bound on a product billed per monthly active user, and there is no retention answer for a compliance review. ## Dormancy is a property of the PAIR DM ids are keyed on the pair (`dm-<a>-<b>`), never on an appointment, and `DM_ELIGIBLE_STATUSES` deliberately includes `COMPLETED` so a finished booking keeps the conversation open. A per-appointment trigger would therefore freeze a live relationship the moment one of its bookings completed. So the job groups by CHANNEL — the id is a function of the pair AND the funding context, so one pair legitimately holds a personal `dm-` channel and a separate `dmo-` per org — and measures against the latest slot across every booking that channel covers. Ninety days, not the event stage's seven. An event ends on a schedule and its chat has a natural tail; a consulting relationship does not, and a fortnight between sessions is ordinary. Deletion follows at the org's `chatRetentionDays`. ## The unfreeze is the part that makes it safe An event never resumes, so a frozen event channel stays frozen correctly. A pair does resume. Without a reversal, the first thing a returning consultee would find is a channel they cannot post in — and because Stream grants `use-frozen-channel` to no role, with no error text explaining why. Freezing without unfreezing would be a worse bug than never freezing. So an active-but-stamped pair is unfrozen, FIRST and outside the per-run budget: a frozen channel belonging to an active pair is a live user-facing fault, while a dormant pair staying unfrozen one more day is not. ## Schema `Consultation.chatFrozenAt` and `Subscription.chatFrozenAt` mirror the existing columns on `Webinar` and `Class`, but are read as MAX() across the pair and cleared across all of them — stamping one row would let a second booking report the channel as unfrozen while it was not. `Organization.chatRetentionDays` defaults to 365, split from `streamRecordingRetentionDays` (90) which chat used to borrow. The two are not the same question: a recording is a stored asset with a storage bill, a chat channel is the written record of a professional consultation. Deliberately NOT clamped to a floor — PR #1266 establishes Rule 8(3) as a narrow preservation-for-State-access duty that does not commence until 13 May 2027, so a hard minimum would over-state what binds us. Migration applied to the shared dev database and verified; purely additive, and recorded at prisma/sql/one-off/2026-09-01-add-dm-chat-freeze-ledger-and-chat-retention.sql. `check-db-drift` green, 118/118. ## The freeze says so before it lands `lib/stream/system-message.ts` is the first `sendMessage` wrapper in the repo — nothing anywhere sent a Stream message from the server before. A frozen channel refuses every send with no error a user sees: they type, nothing happens. So the freeze posts a system notice first, and the order is load-bearing, because a message sent after the freeze would itself be refused. ## Also Two chat features were dead code. `client.on("*.**", handler)` registers under the LITERAL string key — verified against the installed SDK, which records `'*.**'` and `'all'` as separate keys and fires only the latter — so the entire live channel-list updater in `ChatSidebar` and every counter in `DebugDialog` have never fired once. The single-argument form is the "every event" listener, which is why `useChatUnreadCount`'s badge updated while the list it points at did not. 351 legacy underscore channels (`webinar_`, `class_`) are declared rather than resolved by accident. They are deliberately NOT added to `MANAGED_CHANNEL_PREFIXES`, which the plan for this work called for: that list makes the reconciler REMOVE a user from any channel carrying the prefix that is absent from the expected set, and the expected set emits `webinar-<id>`, never `webinar_<id>` — so all 351 would be classified stale and their members removed on the owner's next dashboard load. That is #1134 P0-7 exactly. Ran `purge-memberless-dms.ts`: 30 phantom channels deleted, all with zero messages, the 6 message-bearing ones preserved by the script's default. 135 → 105 channels, re-run confirms 0 candidates remain, pre-image on disk. ## Verification 331 suites / 3636 tests green, cold tsc clean, eslint clean. The DM stage goes from no coverage to 12 tests, each proved by disabling the behaviour it pins: removing the unfreeze branch reds 2, sending the notice after the freeze reds 1, measuring dormancy on the oldest booking instead of the newest reds 3. Part of #1280 Closes #1270 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(stream): never hard-delete a DM from a page that may be incomplete CodeRabbit round on #1303. Seven findings, all legit, one of them serious. ## The critical one: truncation could destroy a live pair's history Both booking queries cap at `MAX_DM_PAIRS_PER_RUN` and order by `requestedAt`, which is NOT the key dormancy is measured on — that comes from the latest slot `endsAt` across the pair. The two are independent, and a long-running booking is requested once and then generates sessions for years, so it sorts old and is the first thing a full page drops. If a pair keeps one low-activity booking on the page and loses its active one, `lastActivityAt` is computed from the stale row, the pair classifies as past retention, and `hard_delete: true` destroys the chat history of a live consulting relationship. Unrecoverable, and silent — nothing recorded that rows had been dropped. The delete stage is now withheld entirely when either query fills its page, the run is marked unsuccessful, and the held-back count is reported. Freezing still runs, deliberately: an over-eager freeze is undone by the next run's unfreeze branch, and withholding it too would be over-correction. ## And an org above 365 days got no deletion at all The scan window came from `MAX_RETENTION_DAYS` (365) plus margin, while `chatRetentionDays` accepts any value. An org on 500 days had every booking dropped by the bound before it could be classified — silently, and in the direction of keeping personal data forever. The window is now derived from the largest value actually configured across all organizations. ## SonarCloud gate `runDmStage` was cognitive complexity 20 and `applyDmFrozen` 16, against a limit of 15. Extracted `classifyDmPairs` (pure, now directly testable), `announceFreeze` and `writeDmLedger`. Behaviour-preserving. ## The rest `deletedDms` counted requests, not deletions — `deleteChannels` is idempotent and returns a task id, so a pair past retention is re-sent every run until it ages out of the scan window. Renamed `dmDeleteRequests`, which is what the number is. Bounded by the lookback rather than unbounded, so the metric was the defect, not the work. `sendSystemMessage` spread `custom` LAST, so a caller key named `type` could override `type: "system"` — the field the docstring calls load-bearing, because a regular message touches unread counts. Fixed ordering; no caller does this today. The channel-identity test proved nothing: it re-derived both ids from `getDmChannelId` and compared them to each other, which passes even if the job addressed the wrong channel or the wrong Stream type. The mock now captures `channel()` arguments and the test asserts the org channel was frozen and the personal one was not — the failure `lib/stream-channel-ids.ts` records as having gone unnoticed for months. Left as-is with a reason: `loadOrgChatRetention` still reads every organization rather than only those with a booking on the page. It has to — the scan window is derived from the largest configured retention, and narrowing it to the orgs already loaded would make the window depend on the page, which is the same incomplete-input-drives-a-destructive-decision shape as the finding above. 15 DM tests now (was 12), each new guard proved red with it disabled. 331 suites / 3639 tests green, tsc and eslint clean.

Documents two sub-rules of DPDP Rules 2025 Rule 8 that the compliance docs did not cover. Grepping
docs/andbugs/for Rule 8(3) returned zero hits before this change.Verified verbatim against the official Gazette PDF — G.S.R. 846(E), Gazette No. 760, MeitY, 13 November 2025 — not against secondary sources.
What was missing
Rule 8(2) — the Data Fiduciary must inform the Data Principal at least forty-eight hours before an erasure period completes.
Rule 8(3) — a minimum one-year retention floor on personal data, associated traffic data, and processing logs, "undertaken by it or on its behalf by a Data Processor." The official Illustration Case 2 is explicitly about a cloud service provider.
The two are scoped differently, and the difference matters:
Scope of the floor
Rule 8(3) retains "for the purposes as specified in the Seventh Schedule." The Seventh Schedule (
[See rule 23(1) and 8(3)]) is a table of State-access purposes, each with a named authorised person:So this is a preservation-for-State-access duty, not a general business-records floor. It is still a floor, it still reaches Data Processors, and it still constrains any delete-on-request design — it is simply narrower than a blanket retention mandate. An earlier draft of these callouts overstated it as unconditional; that has been corrected.
The gap this surfaces in real code
lib/compliance/erasure/scrub-user.tsnever computes a one-year-from-processing date. An erasure request filed within a year of processing therefore cannot fully purge non-financial rows either — not just the money rows the existing tombstone-scrub rationale covers. That rationale is correct as far as it goes and is left untouched; the floor is documented beneath it.Discharging Rule 8(3) against a third-party processor means being able to show the vendor also retained for a year and being able to cause that vendor to erase under Act §8(7)(b) once the floor clears. Neither is implemented. This is the strongest argument against a third-party helpdesk holding support message bodies — stronger than data residency, since DPDP imposes no general localisation mandate (see #1265).
Also corrected here
06-cross-cutting-integrations.mdcarried a note sayinglib/compliance/dpdp.tshad an off-by-one ("14 May 2027") awaiting a fix. Verified against the live file — line 19 now reads13 May 2027 — not 14 May. The note is stale and is updated to record the fix as landed. The two-stage Rule 7 modelling gap described in the same bullet remains open and is untouched.The
02-deletion-policy.mdcarve-out is attributed to Act §8(7), not Rule 8(1) — Rule 8(1) carries identical wording but binds only Third Schedule classes, which we are not.Not changed
No commencement dates were touched. The repo's 13 Nov 2025 / 13 Nov 2026 / 13 May 2027 phasing is correct and was re-verified against the Gazette masthead (
No. 760] NEW DELHI, THURSDAY, NOVEMBER 13, 2025). Rule 8(2)/(3) commence with the rest of Rule 8 on 13 May 2027.Docs only — no code, no schema, no tests.
Part of #1265.
