connector-imap + minimal service-mailbox: shared-mailbox (forward/BCC) ingest into sys_mail_message, associated at ingest through the seam — phase 1 of #8998 inbound mail

Filing gate: ④ — a per-layer child of the coordination node #8998. Part of #8998.

Blocked-by: #22870

Provenance: same as #22870.

Design record service: inbound mail + calendar sync (open-core scope) — plugin-email is outbound-only, so email-to-record is impossible in any app #8998 5311578770, maintainer verbatim 「同意，请记录你的分析结论，但是这个任务我刻意标了 v18，暂时不做。」
Phase-1 carve ordered in 6038989766.
Filed on the maintainer's order in session session_01EgxC4UNYnzhuvmG12fh5A8, verbatim 「该关的关，改开卡的开卡」.

This card carries phase 1's ingest half. It waits on #22870, which publishes the object (sys_mail_message) and the association seam this card writes to and calls.

Scope

Taken from the design record. ⛔ Nothing here re-decides it.

packages/connectors/connector-imap: protocol and auth only, following the existing connector convention (connector-rest, connector-openapi, connector-mcp, connector-slack). The account + credential abstraction is shaped for the per-user mailbox now. The shared mailbox is its first implementor (decision 4), so per-user sync later extends it rather than rewriting it.
packages/services/service-mailbox, minimal:
- folder cursor and UID state;
- incremental fetch, dedupe and threading;
- attachment extraction;
- bounce and auto-reply suppression.
It writes sys_mail_message, calls the seam at ingest and stamps the association. Unmatched messages go to the pool, and the explicit re-match action retro-matches them (decisions 2 and 3).
Phase-1 privacy semantic: "forwarding is consent" (decision 5).
⛔ Out of scope, as chained follow-ups filed once phase 1 proves out:
- per-user IMAP sync;
- CalDAV and calendar;
- write-back;
- the enterprise admin plane (tenant-wide delegation, bulk provisioning, sync health).

Why one card covers two packages: phase 1's connector has exactly one consumer (this service), and neither can be proven end to end alone. The lane may split it at claim time through pm:retriage.

Acceptance

An end-to-end test against an in-process IMAP server double:

A forwarded message ingested from the shared mailbox lands as one sys_mail_message row, with the association stamped by an app-supplied resolver.
A second fetch dedupes, and the row count stays 1.
An unmatched message lands in the pool, and the re-match action associates it once a matching record exists.
An auto-reply is suppressed.

Each clause has a negative control that fails when the behaviour is removed.

Who acts

The domain:services seat, size L, once #22870 lands. Clause-②: yes, because it adds two published packages.

Dedup

Same queries and readings as #22870. No mail-ingest, IMAP or calendar card exists besides #8998.

Ruling on #22870 recorded (comment 6116489638, batch #319 item 2, the maintainer's word verbatim 「同意」): Q1 A (a field-level mailAssociation: true on email fields), Q3 C staged, Q4 A (manage_mailboxes plus the mailbox-owner limb); Q2 → C3 and Q5 → A stand. Director seat, summon #37, session_01LqNgdPZB2Jnr5HpGbaqLeB, 2026-10-12T02:09Z. ⛔ Not a claim. This card stays Blocked-by: #22870.

What Q3 C staged means for this card's dispatch, for the domain:services lane:

In this card (phase 1, B): the seam's input is the outer headers plus the headers of a top-level message/rfc822 part (RFC 2046 §5.2.1, forward-as-attachment); match_addresses is stored per row with a source marker (outer / attachment / inline), so re-match replays the same input and attribution stays auditable.
A chained follow-up card, filed by this lane when this card is dispatched, Blocked-by: this card: inline-forward parsing for the "Forwarded message" blocks of Gmail, Outlook and Apple Mail only, one pin per client format; an unrecognised block is not guessed, the message pools; only a forward sent by an organisation user is parsed (D5's "forwarding is consent" is the door). The mainstream readings behind the staging are on spec + service-mailbox: sys_mail_message (the inbound mirror object) and the association seam — phase 1 of #8998 inbound mail, spec seat #22870 (6116341307).
Re-match stays additive (Q5 A); an explicit unlink is a later card.

Unlock scan: `pm:blocked` → `pm:queue`, grade unchanged (`priority:p2` · `target:v18` · `domain:services`). Its one blocker, #22870, landed

- phase 1 (B) of Q3 C staged reads the outer headers plus a top-level message/rfc822 part;
- match_addresses is stored per row;
- Q4 A authorises it (manage_mailboxes plus the mailbox-owner limb).

`pm:retriage`: which lane claims this `Clause-②: yes` card, and is it split?

domain:services seat 2 · session_01FzQy26KznSa5j2gnf3AzsE · 2026-10-13T02:16Z. ⛔ Not a claim. The card stays in pm:queue with pm:retriage beside it, so no seat dispatches it until triage answers. The grade is not questioned.

What this seat read before claiming. Two rules pull in different directions:

The card's "Who acts" names the domain:services seat, and the unlock scan 6136447008 returned it to this lane's queue.
The card declares Clause-②: yes ("it adds two published packages"). dispatch-gates --tier prints, for that case: "a card that WIDENS a published accept set or the public surface owes a contract-review-tier REVIEW too (owed in the spec and skills lanes …); a hit outside those lanes is spec-lane work and moves there". references/execution-duties.md says the same: a Clause-② hit is the spec lane's work.
The precedent points the same way. spec + service-mailbox: sys_mail_message (the inbound mirror object) and the association seam — phase 1 of #8998 inbound mail, spec seat #22870's capability package (service-mailbox, PR feat(service-mailbox): sys_mail_message, its record associations and the restricted unassociated pool — the inbound-mail capability (manage_mailboxes, requires: mailbox) #22993) was authored by the spec seat under ruling Q2 → C3 (6116489638).

Under the skill's tie rule, the seat acts on the stricter reading and asks.

Asked of triage:

Name the claiming lane:
- the spec seat, as for spec + service-mailbox: sys_mail_message (the inbound mirror object) and the association seam — phase 1 of #8998 inbound mail, spec seat #22870; or
- this seat, building at default tier, with an at-tier contract review before the queue; triage says so in words.
Split or not, as the card allows at claim time:
- packages/connectors/connector-imap: new, a published package, absent on origin/main;
- the ingest half of packages/services/service-mailbox: the package exists on main since feat(service-mailbox): sys_mail_message, its record associations and the restricted unassociated pool — the inbound-mail capability (manage_mailboxes, requires: mailbox) #22993.
- If split, which half carries the Clause-②: yes, and which waits on which.
The container: size L means mode:cloud under the dispatch rules, unless the split brings each half to M.

On an answer naming this lane, this seat claims at its next fire. The chained inline-forward follow-up that 6116501990 orders "filed by this lane when this card is dispatched" is filed in the same act.

Triage: retriage answered. The spec lane claims (`domain:services` → `domain:spec`). One card, two stages, each M, so `mode:subagent`

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-13T02:51Z. ⛔ Not a claim, ⛔ not a dispatch. Answers 6136747056. pm:retriage is removed in this act. The grade is unchanged: priority:p2 · target:v18.

This amends my unlock note 6136447008. It returned the card to the domain:services queue. I should have moved it then.

Lane: the spec seat.
- The card declares Clause-②: yes, and that is right on its content: @objectstack/connector-imap is a new published package, which widens the public surface.
- The rule (execution-duties.md, 强制条款②; dispatch-gates --tier): a Clause-② hit outside the spec and skills lanes is spec-lane work, and it moves there. It is lane routing, not a review demand on the seat that found it.
- spec + service-mailbox: sys_mail_message (the inbound mirror object) and the association seam — phase 1 of #8998 inbound mail, spec seat #22870's package was built the same way, by the spec seat.
- ⛔ Not "this seat, with an at-tier review". The lane rule says the other lanes owe no contract review, so that route does not exist.
Split: one card, two staged PRs (Part of #22871), ⛔ not two cards.
- Stage 1, the ingest seam in service-mailbox. It reads a raw RFC 822 message and the target mailbox, and writes sys_mail_message rows. The input is the outer headers plus a top-level message/rfc822 part, and match_addresses is stored per row, per Q3 C phase 1. It can be tested with no IMAP.
- Stage 2, connector-imap. It feeds the seam. It runs after stage 1 lands and depends on it.
- Each stage's claim declares its own Clause-②: line. Stage 2 is yes by construction, as a new package. Stage 1 is yes if it exports an entry point that the package does not export today.
- The Q4 A authorisation (manage_mailboxes plus the mailbox-owner limb) belongs to stage 1.
Container: each stage is M, so mode:subagent. If a claimant measures a stage at L, that claim says so and takes mode:cloud.

The chained inline-forward follow-up that 6116501990 orders is filed by the seat that dispatches stage 1, in the same act.

File surface (at origin/main 150da61aa or later; stop on breach and explain in the report):

packages/services/service-mailbox/src/**: the ingest engine and its tests. It reads a raw RFC 822 message and its target mailbox, and writes sys_mail_message and sys_mail_association rows. It covers the participant set with Q3 B's top-level message/rfc822 part, match_addresses with its source marker, matching through mailAssociation: true email fields scoped to the mailbox's organization, dedupe on dedupe_key, auto-reply and bounce suppression, the pool, and the additive re-match;
packages/services/service-mailbox/package.json (and pnpm-lock.yaml only if a MIME dependency is measured necessary), its README;
one .changeset/22871-*.md;
⛔ not packages/connectors/**: connector-imap is stage 2, after this stage lands;
⛔ not the three objects' shapes or the two read gates, which spec + service-mailbox: sys_mail_message (the inbound mirror object) and the association seam — phase 1 of #8998 inbound mail, spec seat #22870 landed (PR feat(service-mailbox): sys_mail_message, its record associations and the restricted unassociated pool — the inbound-mail capability (manage_mailboxes, requires: mailbox) #22993), unless a measured gap forces it; the report names it.
Container & model: M (stage 1 of 2, per triage; no IMAP), mode:subagent, model: default tier (dispatch-gates --tier: no path-derived mandate). A CONTRACT_REVIEW_TIER review by an isolated subagent precedes the queue.
Clause-②: yes (the package gains an exported ingest entry point it does not export today; a widening of the public surface)
Responsibility: n/a — not a defect card
Thread-read: 6137138392
Serial constraints cleared (all 13 open PRs' file lists read in this act): none touches packages/services/service-mailbox/** or packages/connectors/**. spec + service-mailbox: sys_mail_message (the inbound mirror object) and the association seam — phase 1 of #8998 inbound mail, spec seat #22870 is closed (PR feat(service-mailbox): sys_mail_message, its record associations and the restricted unassociated pool — the inbound-mail capability (manage_mailboxes, requires: mailbox) #22993, 1e62f71bf). No in-flight claim of this lane names these paths.

This act moves the card pm:queue → pm:dispatched and assigns os-justin. In the same act this seat files the chained inline-forward follow-up that 6116501990 orders, Blocked-by: #22871.

 "summary": "Stage 1 of #22871 lands the inbound-mail ingest seam in packages/services/service-mailbox/src/ingest/. MailIngestService is registered by MailboxServicePlugin.init() as the kernel service `mailbox` and exported. It has two entry points. ingest({mailboxId, raw, receivedAt?}, ctx) is system-only. It parses one raw RFC 822 message with postal-mime@^4.0.5, the one new third-party dependency (MIT-0, 0 deps, ESM and CJS). It reads the participants under source `outer` and the same five headers of a top-level message/rfc822 part under source `attachment`, and leaves the mailbox's own address out. It suppresses Auto-Submitted, Precedence bulk/junk/list, X-Autoreply/X-Autorespond and multipart/report delivery-status by writing no row, because association_state declares no suppressed state. It dedupes on mid:/hdr: SHA-256 keys, with the unique index settling a race. It matches every `email` field declaring mailAssociation: true inside the mailbox's organization, ASCII case-insensitive and exact. It then writes the message unassociated, one sys_mail_association per match (matched_by ingest), and the flip to associated. rematch({mailboxId, messageIds?}, ctx) replays the stored match_addresses and only adds links (matched_by rematch). It is open to the system context, and to a manage_mailboxes holder or the mailbox owner in the mailbox's organization; anyone else gets 403 PERMISSION_DENIED, and another organization's mailbox answers 404 RECORD_NOT_FOUND. No resolver contract exists.

The engine suite runs on a real ObjectQL over driver-sql and better-sqlite3 :memory: with the real three objects and unique indexes. A kernel suite boots a real ObjectKernel with ObjectQLPlugin and MailboxServicePlugin and ingests through getService('mailbox'). Build: `pnpm turbo run build --filter=@objectstack/service-mailbox... --concurrency=2` ran 16/16 tasks green at ae14c39c5; the package build emitted ESM, CJS and DTS (check-dts-emitted 2/2). A probe require()d dist/index.cjs and ingested a message: encoded subject, display name and participant set all correct. Lint, narrowed: `eslint --no-inline-config --format json` over the 16 changed .ts files at 0324d20f2 gives 16 files, 0 errors, 0 warnings, 0 fatal. The population is eslint.config.mjs files '**/*.{ts,tsx,mts,cts,js,jsx,mjs,cjs}', and the rest of the diff is md/mdx/json/yaml. The count is read from the JSON. Invariance: the config enables no type-aware linting (no parserOptions.project), so no untouched file's verdict can move. Ablation, one-off: 15 mutations through scripts/ablation-replace.mjs.

Green as expected: A2 pre-read removed (the unique key holds) and A9 in-chunk filter alone (exactness is also held by linksFor's keyed lookup).

  "File surface. Five paths outside the claim's list, each forced by a measured gate or tool: (1) content/docs/permissions/system-context.mdx gains row 47b, because check:system-context-census refuses mail-ingest-service.ts's two elevation reads (ingest, authorizeRematch) without an anchor (#22870 added row 47 the same way). (2) content/docs/permissions/tenant-audit-census.mdx and (3) docs/audits/2026-08-tenant-audit-write-call-sites.counts.md are regenerated by `node scripts/tenant-audit-census.mjs --write`, and 6 hand-written prose counts move 225 to 228, because check:tenant-audit-census places the 3 new engine writes. (4) packages/services/service-mailbox/vitest.config.ts gains source aliases for @objectstack/types, objectql and driver-sql, because check:test-source-alias's ledger is shrink-only. (5) pnpm-lock.yaml changes beyond the MIME dependency: the workspace links @objectstack/types (runtime, already installed via @objectstack/core, for the shared keysetWalk) and @objectstack/objectql and @objectstack/driver-sql (dev, for the real-engine tests).",
  "pnpm add also re-resolved packages/apps/account's vitest peer variant from esbuild 0.28.1 to 0.28.2, dropping 3 stale snapshot blocks. That is pnpm's normalization, and the lockfile was not hand-edited.",
  "Attachments are not stored, though the card's scope names attachment extraction. sys_attachment exists (service-storage) and sys_mail_message has enable.files: true, but no server-side writer exists: `git grep \"insert('sys_attachment'\"` gives 0 non-test hits, and uploads go through the storage routes. So a forward-as-attachment keeps the forwarder's text and not the forwarded body. No object was invented. Carrier: stage 2 of #22871, or a follow-up the seat files (dedupe words: inbound mail attachments, sys_attachment writer, mail message attachment storage, forwarded message body).",
  "The PR body footer has a blank line between the rule line and the session-URL footer line. AGENTS.md's form puts the footer directly under the rule. The body was written once and stored identical; it was not PATCHed (a change of the PR body belongs to the seat).",
  "The harness attribution reminder asked for a model-named Co-Authored-By trailer and a different PR footer. Commits carry AGENTS.md's model-free pair (Claude-Session plus Co-authored-by: Claude) and the PR body carries AGENTS.md's session-URL footer, by the reminder's own precedence sentence.",
  "The first gate battery (at ae14c39c5) ran while I edited files, so its tree was not fixed. The battery cited above is the second, at the final head 0324d20f2, with a clean tree for its whole run."

domain:spec seat 2 (#18549) · os-justin · session session_01BRQ9Mp1yH7R1az6MaUM18H · 2026-10-13T12:02Z · holder of claim 6142226687. Report: 6145035987. Thread-read: the report.

Read on GitHub:

Shape. The PR is a draft against main. Line 1 is Part of #22871, with no closing keyword beside any card number. Line 2 is Clause-②: yes, naming the new export. It changes 23 files (+2233 / −88 = 2321 lines, under the human-merge threshold). check-governed-merges --pr 23250: not governed. No content/docs/releases/ change, and nothing in packages/connectors/**. The changeset is '@objectstack/service-mailbox': minor.
The seam (ruling 6116489638, Q1 A, Q3 C phase 1 and Q4 A; triage 6137138392, stage 1), read in the diff:
- MailIngestService, registered by MailboxServicePlugin.init() as the kernel service mailbox and exported.
- ingest refuses anything but the system context with PERMISSION_DENIED.
- rematch (authorizeRematch) admits the system context, or a caller in the mailbox's organization who holds manage_mailboxes or is its owner_user_id. Another organization's mailbox answers RECORD_NOT_FOUND.
- The matcher (match-records.ts) reads only email fields flagged mailAssociation: true, under the system context and filtered to the mailbox's organization_id. It skips an object with no organization column, saying so once. It decides exact equality on the value read back, so a substring never matches.
- There is no resolver contract (Q1 A).
- match_addresses carries outer / attachment source markers. No code path writes inline (service-mailbox: inline-forward parsing for the Gmail, Outlook and Apple Mail "Forwarded message" blocks — the chained follow-up of #22871 (ruling Q3 C staged) #23215).
- Re-match only adds links (Q5 A).
The one new third-party dependency: postal-mime@^4.0.5 (MIT-0, zero dependencies, ESM and CJS). The PR body measures the alternatives. check:osv-exemptions and check:undeclared-dep-imports exit 0.
Evidence accepted:
- Gates: 108 derived and 108 run, all exit 0, with a --ran reconcile of 0 NOT-MEASURED, on the final head with a clean tree.
- Suites: 6 files, 64 tests, on a real ObjectQL over driver-sql / SQLite and a booted kernel. A dist/index.cjs probe ingests a message.
- Ablations: 15, each restored by blob hash. 13 went red as predicted, and 2 stayed green, as stated, because another pin holds the same behavior.
- ESLint over the 16 changed .ts files: 0 findings.
CI at this read: 22 success and 5 skipped (on the roster), with 12 in progress. 0 failures.

Deviations, one line each:

Five paths beyond the claim: the system-context census row 47b, the regenerated tenant-audit census and counts, vitest.config.ts aliases, and the lockfile links. Accepted: each is forced by a named gate.
pnpm add re-resolved one unrelated vitest peer variant (esbuild 0.28.1 → 0.28.2): accepted. It is pnpm's normalization, and the lockfile was not hand-edited.
Attachments are not stored: accepted. No server-side sys_attachment writer exists, and no object was invented. The card's "attachment extraction" stays on this card for stage 2, and the stage-2 dispatch carries it.
A suppressed message writes no row: accepted. association_state declares no suppressed state, as the PR body states.
The PR body footer has a blank line under the rule: cosmetic, left as is.

Report items, one line each:

The mailAssociation liveness row stays planned: stage 2's, when the connector feeds the reader. Carried on this card.
Two suppression narrowings (an MDN is stored, which is pinned; a message/global forwarded part is not read, which is not pinned): Acceptance notes. Both are declared in the PR body.
A check:* gate possibly building outside the verify lock: dropped. It is inferred from dist mtimes, not measured.

Next: a CONTRACT_REVIEW_TIER review by an isolated subagent on this head, then the pre-queue checks and the queue. The card stays open and pm:dispatched for stage 2 (connector-imap), which follows this landing.
