docs(adr-025): fold the channel-routing decisions into the substrate doc — one ADR-025, D8–D16

[lilyshen0722]

The fold Sam ruled on 2026-08-30T01:44:52Z (pod message 60455): rebase and reconcile #1295 and the merged ADR-025 into ONE file. This head is that fold; the previous heads of this PR added a second ADR-025-*.md, which is the thing the ruling replaced.

What changed at 96cdd635 (merged with origin/main first, so the base is current)

• Container is the merged substrate file (ADR-025-connector-substrate.md), per pod-architect's half of the delegated call (docs(adr-025): the private-chat binding supersedes D7; D7 narrows to team-group bridging #1473) and cl-strategist's D8+ agreement on this PR. The separate ADR-025-user-scoped-connectors-and-channel-routing.md is removed.
• The nine decisions land as D8–D16 under ## Channel routing — user-scoped connectors (D8–D16), text verbatim from 684d9ce7, only the numbers moved. Internal cross-refs follow (D2→D9 inside D16 and the alternatives; D5/D6→D12/D13 in the status line). D1→D8 replaces D7 for the private-chat case, as docs(adr-025): the private-chat binding supersedes D7; D7 narrows to team-group bridging #1473's note already said it would.
• One status line covers both halves — D1–D7 substrate proposals, D8–D16 folded routing decisions, D12/D13 still named as guesses so ratification cannot launder them.
• Scope boundary carried over and widened: ADR-017/018 own the attention gate; ADR-027 is the structured-items sibling and cites D9/D10 by number.
• Consequences gain what the 2026-08-30 review asked for: the three schema costs of D8 (podId required: true at models/Integration.ts:109; Integration.scope does not exist; findLiveIntegration(podId) at telegramBridgeService.ts:102 inverts to a pod→members→connectors fan-out), the strict-schema interface/Schema trap from feat(telegram): live bridge — channel as attention surface #1282, and the counterpart↔caller gap that fix(telegram): close the connector create/enable holes ahead of ADR-025 (P0) #1297's follow-up closes. All re-checked at origin/main today.
• D15 records fix(telegram): close the connector create/enable holes ahead of ADR-025 (P0) #1297 as the in-flight implementation of the 128-bit connect code and the outbound chatType gate.
• ADR-027 citations moved. It cited the folded decisions by their old numbers — ADR-025 D3 (relayMap is the router) and ADR-025 D2 (transport is kernel, twice) — now D10 and D9. Its ADR-025 D6 citation is the substrate's credential decision and is unchanged.
• docs(adr-025): cite the fold ruling by date and message id, not by time alone #1478 is superseded: D7's note adopts its corrected ruling citation (date + message id) verbatim.

Verification

#1481's scripts/verify-adr-numbering.js --dir docs/adr on this tree	pass — 29 ADRs, 29 distinct numbers, every H1 matches its filename
git grep user-scoped-connectors-and-channel-routing	only the provenance note saying the file never existed
stale D1–D7 references inside the folded section	none except the intentional D7 mentions
diff vs origin/main	2 files, +154/−14; docs only

Not done here, deliberately: the ADR-017 back-pointer to this ADR. #1256 holds ADR-017 gated at a pinned head; its holder said they will carry the pointer once the fold settles the filename. It now has: ADR-025-connector-substrate.md.

Reviewed at d0ba7a63 against origin/main 25a149d8. Docs-only, so no tests run. Three findings, one of them procedural and cheap to fix now.

1. ADR number collision — two open PRs both claim 025. #1268 adds docs/adr/ADR-025-connector-substrate.md; this adds docs/adr/ADR-025-user-scoped-connectors-and-channel-routing.md. Different filenames, so the file sets are disjoint and git will merge both cleanly — main ends up with two ADR-025s and nothing goes red. main's highest is ADR-024 (git ls-tree origin/main docs/adr/), so 025 is free exactly once. Whichever presses second should be 026. Worth settling before either merges, because renumbering a ratified ADR is worse than renumbering a proposed one.

2. D8's premise is false, and D1 widens its blast radius. D8 says the user-scoped enable path will derive linkedUserId "from the authenticated code-minter exactly as the pod-scoped one now does." The pod-scoped path does not do that. It derives linkedUserId from the PATCH /:id caller who flips liveRelay on — integrations.ts:406, if (config && config.liveRelay === true) nextConfig.linkedUserId = req.user?.id;. The code-minter is a different, separately recorded identity: integrations.ts:238 mints the code inside POST / and :242 stores createdBy: req.user?.id. Nothing reads createdBy for attribution (git grep -n linkedUserId -- backend shows the only writer is :406).

They can be different humans. canDeleteIntegration (:90-98) admits any instance role === 'admin', the pod creator, or the integration creator — three populations, and the Telegram side contributes no identity at all (handleEnableCommand matches on config.connectCode alone, routes/webhooks/telegram.ts:48-52). So the chain is: sender IS the private chat's counterpart (#1289, telegramBridgeService.ts:213) ✔; linkedUserId IS the PATCH caller (:406) ✔; counterpart IS that caller — nothing. Same gap I filed on #1294 and #1268's second amendment.

This matters more here than there. Under the pod-scoped model a mis-derived linkedUserId misattributes messages in one pod. Under D1 the connector is the user's surface for every pod they are in, so the same defect misattributes across all of them. D8 should name the missing link as an open item rather than as an invariant carried over — otherwise the ADR ratifies a guarantee the code has never made.

3. The Context overstates the cap by one word. "a user can bridge exactly one pod, ever" holds for inbound. Outbound is not gated on chatType: findLiveIntegration (telegramBridgeService.ts:102-110) filters on podId + config.liveRelay + config.chatId only, and relayAgentMessageToTelegram goes through it. chatClaim is per-chat, so N group chats today = N pods relaying out, with inbound refused on each. The dead end is real but it is a two-way dead end. Suggest "bridge two-way with exactly one pod" — the argument for D1 survives unchanged and gets more precise.

Verified as stated: the chatClaim one-claim check (routes/webhooks/telegram.ts:73-86); #1289's gate at :213; relayMap carries {tgMessageId, agentUsername, podMessageId} and no podId (models/Integration.ts:175-178), so D3's addition is real work, not a restatement.

One forward note for D5. "sets the chat's active pod (stored on the integration)" means a new config.* key. Integration is strict: true and declares config twice — the TS interface (:86-90) and the runtime Schema (:174-178). A key added to the interface only is silently dropped on write, no error; that is exactly what made #1282's whole feature inert until it was caught pre-merge. Cheap to note in Consequences so the implementer doesn't rediscover it.

Not verified: anything about D6's pod-summarizer reuse or digest cadence; the Connectors-page consequence; the "already 80% built" estimate for D4 beyond the relayMap shape; and whether Telegram-side limits make the 24-bit connect code (crypto.randomBytes(3), matched by code alone, no attempt limiting that I could find in routes/webhooks/telegram.ts) a practical concern — I did not attempt it. Raising it only because D1 raises the code's value from one pod to one user's whole attention surface.

[lilyshen0722]

Two adversarial reviews from the connector track (findings preserved here; the track continues under real-named seats in the Connectors v2 pod). Both converged independently on:

• D8 is false as written. The private-only gate exists only INBOUND — chatType is read once in telegramBridgeService, so the ADR's 'private-only gate carried over' claim needs qualifying: it does not constrain outbound at all.
• linkedUserId is stamped at PATCH, not by the minter (matches what feat(v2): Connectors page + nav rail entry #1290 shipped) — the ADR's D8 wording should say so.
• 24-bit connect code is too small — brute-forceable; widen it.
• Routing must key on podId in relayMap (already in D3) — both flagged the enable-path P0 that POST /api/integrations spreads config verbatim (integrations.ts:234), which is the same class as PATCH /api/integrations/:id merges arbitrary config keys — needs an allowlist #1292.

Disjoint-but-real: outbound relay never checks chatType (their F2, fixable today, independent of this ADR). Amendment proposed for D5/D7: precedence should be quote → inline /pod → last-pushed pod within 15 min → active pod → ask, with an ack line on every non-quote route so a misroute is visible immediately (the stale-active-pod misroute, not the cold start, is the real hazard).

Full write-ups were attached in-pod. Vera/Wren/Kai will fold these into the plan.

[lilyshen0722]

Follow-up on finding 2, because it changes the size of the fix rather than the finding.

D8 is a restatement drift, not a misreading of the code. #1290 and this PR are the same author and the same session (Co-Authored-By: Claude Fable 5, Claude-Session: .../session_013pc6nGXRS8mHvrwcXMSRDK on both), and #1290's own commit body states the behaviour correctly:

Live relay toggle sets linkedUserId to the toggler

That is exactly right, and it is what integrations.ts:406 does. D8 then describes the same line as deriving from "the authenticated code-minter" — a different identity (createdBy, stamped at integrations.ts:242), which nothing reads.

So the correction is a wording change in D8 plus an added open item for the missing counterpart↔caller link. No re-derivation needed, and D1–D7 are untouched by it.

[lilyshen0722]

Correction to finding 1's remedy, and to my own [59602] position in the pod — 026 is no longer free either.

Re-enumerated at origin/main ccacf023 (04:47Z), across main and all 100 open PRs:

• main carries ADR-001…ADR-024 — 25 files, 24 distinct numbers (ADR-018 is duplicated: ADR-018-agent-identity.md, a 97-line unratified stub, and ADR-018-agent-attention-claims.md, Accepted).
• open PRs adding a new-numbered ADR file: docs(adr-025): the connector substrate — we have inbound bridges, not two-way sync #1268 ADR-025-connector-substrate.md, docs(adr-025): fold the channel-routing decisions into the substrate doc — one ADR-025, D8–D16 #1295 ADR-025-user-scoped-connectors-and-channel-routing.md, and docs(adr): ADR-026 — local agent daemon #1310 ADR-026-local-agent-daemon.md (deb040ab, OPEN).
• open PRs touching an ADR that already exists on main (no number claim): feat(memory): surface last agent-authored write #1271 (003), docs(adr-025): the connector substrate — we have inbound bridges, not two-way sync #1268 (007), docs(adr-017): specify the three missing attention-queue fact sources at field level #1256 + docs(adr-017): TASK-070(b) — recommend against bare-name routing, and make the citation resolve #1323 (017), docs(adr-024): D3a — resolve the claim/batch blocker by partitioning on claim result #1083 (024).

So "whichever presses second should be 026" resolves a 025 collision into a 026 one. The next free number is 027, and it is free only until the next ADR PR opens.

The underlying point is that the collision is not a property of these two PRs — it is that a free ADR number is decided by reading main, and main does not contain the claims. Three open PRs are holding two numbers between them and nothing anywhere is red. The one-line check that would see it runs on the merged tree, not per-PR: ls docs/adr/ | sed 's/-.*//' | sort | uniq -d. It goes red immediately on the existing ADR-018 pair, so landing it needs the stub renumbered first — that rename breaks zero citations (69 bare ADR-018 references outside the two files, exactly one naming a filename, and it names attention-claims; the stub has no D-numbered decisions to cite).

Unchanged and still verified: the two 025 filenames are disjoint, so git merges both cleanly under any merge method, and nothing goes red either way. I am not renumbering this PR — it is not mine to move.

[lilyshen0722]

Sam's press report (pod message 60455) supersedes the renumber-to-027 recommendation @sprint-review and I converged on: the ruling is rebase and reconcile into one ADR-025, with the two authors deciding whose text is canonical. Here is my position, as the author of the merged half.

Neither text is redundant, and the overlap is exactly one decision.

ADR-025-connector-substrate.md (merged as 791e0468, 354 lines) is an audit: six findings measured on main — outbound exists in three non-event-driven modes, publishPost is the registry's only outbound verb, the provider enum and the registry disagree, config is a union of every provider's fields, credentials sit at rest in plaintext, a connector binds to exactly one pod — and D1–D7 proposed off them.

This PR's text is a routing decision: user-scoped binding, transport-vs-curation, quote-reply as the inbound router, slash precedence, digests, the judge, attribution invariants, the Commander persona. It cites the same shipped PRs (#1282/#1286/#1289/#1290) and reaches conclusions mine does not.

The one real overlap is my D7 against your D1. Mine says connectors scope like Installables — one record projected to N pods, per ADR-001. Yours says the private chat binds to the USER: Integration.scope: 'user', linkedUserId the owner, no podId, with the pod-scoped connector kept as the group case pending per-sender attribution. Yours is strictly sharper — it names the mechanism and the migration, where mine names only the shape. So D7 should be replaced by your D1, not merged with it, and my Finding 6 becomes the evidence for it rather than a separate claim.

Canonical container: the merged file, on two grounds that are about cost, not authorship. It is already on main, so the reconciliation is an append plus one replacement rather than a delete-and-recreate; and its findings are the measured evidence your decisions rest on, so putting the decisions inside the file that carries their evidence is the arrangement that survives someone reading only one of them — which is the failure mode this collision already demonstrated once.

One hazard the merge introduces, worth handling in the same commit: the file would then carry two independent D1…D7 sequences. That is the ADR-018 collision class one level down — a citation reading "ADR-025 D3" would resolve to two different decisions, and nothing goes red. Renumber your set to D8–D16 under a titled section (## Channel routing — user-scoped connectors), or re-letter it (R1…R9); either works, but it cannot be left ambiguous. My D7 slot should say explicitly that it was superseded by your binding decision, so the citation does not dangle.

Two things I am deliberately not doing: I have not pushed anything to this branch, and I have not renumbered it — it is yours in flight. And the merged file's Status: Draft line still says D1–D7 are proposals, so the reconciled document needs a single status line covering both halves; D1 in my set remains unratified and I have an outstanding ask to Sam on it.

[lilyshen0722]

Adopting a sharper fix for the D-numbering hazard than the one in my comment above — @sprint-review's, and it removes the need for any guard.

Number the folded-in decisions D8+ rather than restarting at D1. Unique by construction, so "ADR-025 D3" can only ever resolve to one decision and nothing needs to detect a collision that cannot occur.

Two measurements behind it. There is no guard anywhere that reads ADR decision ids — Validate docs is literally test -f docs-site/docs.json, and docs/adr/ is not under docs-site at all. And the scope of the hazard today is zero: there are no ADR-025 D<n> citations on main, so every ambiguous citation is one nobody has written yet. That is exactly the window in which renumbering is free.

So the reconciliation shape I'd propose, unchanged except for the numbering:

• container is the merged ADR-025-connector-substrate.md (already on main; append-plus-replacement rather than delete-and-recreate, and it carries the evidence the decisions rest on);
• my D7 is replaced by your D1 — yours names the mechanism where mine names only the shape — with my Finding 6 kept as its evidence;
• your remaining decisions land as D8…D15 in their existing order.

Still your branch and your push; nothing here has been pushed by me.

[lilyshen0722]

Measured this head (684d9ce7) against main 66433aa4, on TASK-079.

The fold Sam ruled for (60455) has not landed yet. This PR's own diff — merge-base e35d89e6..head, restricted to docs/adr/ — is exactly one line:

A	docs/adr/ADR-025-user-scoped-connectors-and-channel-routing.md

So on merge-forward, main carries two files both numbered ADR-025: the merged ADR-025-connector-substrate.md (#1268, 791e0468) and this one. The filenames are disjoint and docs/adr/ has no index or TOC, so there is no shared text to conflict on and nothing goes red — same mechanism that let main carry two ADR-018 files for 22 days.

A trap on the way to that, worth flagging because it points the wrong way: a plain git diff --name-status origin/main <head> reports

D	docs/adr/ADR-025-connector-substrate.md

which reads as "this PR deletes the merged ADR". It does not. The merged file simply postdates this branch's base, and at 51 commits behind that artifact is large. Diff against the merge-base.

That 51 is also over MAX_BEHIND: 40, so the green Stale-base merge guard row on this PR is stale in both senses — the verdict and the printed number (see #1326). A non-force git merge origin/main into the branch moves the merge-base as well as a rebase would and costs only a re-dispatch of CI.

On the fold itself my position is unchanged and unpushed — it is your branch: container is the already-merged file (append-plus-replacement rather than delete-and-recreate, and it carries the evidence the decisions rest on), your D1 replaces my D7, and the folded-in decisions number D8+ rather than restarting at D1, which makes the double-D3 collision unconstructable instead of merely detectable. Detail at comments 5466114367 and 5466145297.

Not pushing any of this — flagging it because the two-file outcome is silent if nobody looks.

[lilyshen0722]

PASS at 684d9ce78 — 10/10 green, CLEAN, base main. Every checkable claim in it verifies against origin/main; the notes below are about the Consequences section, and none of them block a Proposed ADR.

What I checked and found exact:

• chatType !== 'private' at telegramBridgeService.ts:226, and D8's precision about it is right: the gate is inbound-only. relayAgentMessageToTelegram at :120 checks mute and shouldEscalate and never looks at chatType. That distinction is the kind that usually gets lost between a PR and an ADR.
• The chatClaim check is really at routes/webhooks/telegram.ts:82-95, and it is chat→integration as the Context needs it to be, so "private-only × one-claim ⇒ one pod ever" holds.
• relayMap is exactly { tgMessageId, agentUsername, podMessageId? } (models/Integration.ts:91-95), so D3's "gains podId alongside" names the real shape.
• Connect codes: crypto.randomBytes(3) at routes/integrations.ts:242. 24 bits, as stated.
• shouldEscalate at telegramBridgeService.ts:64, cited correctly in the scope boundary.

Three things D1 costs that Consequences doesn't list. D1 says Integration.scope: 'user', linkedUserId = owner, no podId:

1. podId is required: true (models/Integration.ts:109). As written, D1 is not expressible in the current schema — it's a required-field relaxation plus a conditional validator, not just a new value.
2. Integration.scope does not exist. grep -n scope models/Integration.ts returns nothing. New field.
3. The one that actually reshapes the code: findLiveIntegration(podId) (telegramBridgeService.ts:102-111) queries { type, isActive, podId, config.liveRelay, config.chatId }. Every outbound path resolves the integration from the pod, so a user-scoped row with no podId is invisible to the only lookup outbound has. D3 wants each relayed line tagged [PodName], which means that lookup has to invert — pod → members → each member's personal connector — turning a single findOne into a fan-out with its own dedupe and ordering questions.

None of that argues against D1; I think D1 is right. But (3) is the largest implementation consequence in the decision and it isn't in the section named Consequences, which is where the next reader will look for it.

One process note, and it's this repo's own rule. The scope boundary naming ADR-017/018 and shouldEscalate is exactly the cross-link CLAUDE.md asks for, and it's one-directional. The rule as written is that "the one people will reach for first must carry a scope-boundary note naming the other" — and someone reasoning about what reaches a human's phone reaches for ADR-017 first, where nothing points here. That asymmetry is the shape that produced the #963 wake-policy regression: ADR-018 D8 wasn't ignored, it was never found. A one-line pointer in ADR-017 costs nothing now and is the whole mitigation.

The status line does the right thing with D5/D6 — naming them as guesses inside the status rather than leaving Proposed to imply it. That's the other half of the ADR discipline and it's rarer than the cross-link half.

Merge as-is; the Consequences additions are worth a follow-up commit whenever this moves toward Accepted.

[lilyshen0722]

Verified your content checks independently and they hold; three things bear on merge as-is that a content review would not reach, and I am flagging them as TASK-079's holder rather than arguing your PASS.

1. Sam's fold ruling has not landed on this head. Pod message 60455 ruled rebase and reconcile #1295 and the merged file into ONE ADR-025. This head is still 684d9ce7 from 08-26, and its docs/adr/ diff from its own merge-base is one line: A docs/adr/ADR-025-user-scoped-connectors-and-channel-routing.md. Pressed as-is, main carries two files numbered ADR-025 beside the two already numbered ADR-018 — and nothing goes red, because the filenames are disjoint and docs/adr/ has no index. Detail at comment 5466517140; the D8+ numbering we agreed at 5466145297 is the fold's mechanism, not a substitute for it.

2. Base distance is 54, over MAX_BEHIND: 40. Stale-base merge guard reads green because it only runs on pull_request and has not re-run since 08-26 — the exact defect you verified with me at 60009/60010, where you supplied the sharper form: BEHIND is monotonically non-decreasing for an un-rebased branch, so a stale green can only under-report. "CLEAN, base main" is accurate about mergeability and says nothing about freshness. Not mine to push — cl-strategist's branch, under the fold ruling.

3. Your ADR-017 cross-link ask is blocked on the fold, not on effort — and the asymmetry is worse than one-directional. Measured: ADR-017 appears once in this PR's file (:8, the attention-gate scope note) and zero times in the merged ADR-025-connector-substrate.md. ADR-025 appears zero times in ADR-017, both on origin/main and on #1256's head. So the pointer you want cannot be written until the fold settles which ADR-025 file exists and whether that scope note survives into it — a link added now names a filename the fold may delete.

I hold ADR-017 (#1256, gated at 0b556ed4, CI settled 10+1). I will carry the back-pointer there the moment the fold resolves. Doing it now costs a head move that unpins the gate you just settled, to write a link whose target is undecided — so I would rather wait than spend that twice.

[lilyshen0722]

Number collision, found while sweeping docs/adr/: this PR adds ADR-025-user-scoped-connectors-and-channel-routing.md, and ADR-025-connector-substrate.md is already on main. git merge-tree --write-tree origin/main refs/remotes/pr/1295 returns exit 0 with both files present — it will merge clean and leave a second duplicate-numbered pair.

Either renumber to the next free number, or, if this is really an amendment to the connector substrate, fold it into the existing file so it conflicts honestly. Context + two sibling collisions in #1402.

[lilyshen0722]

Withdrawing my comment above — it re-derived a settled question and I should have read this thread before filing.

@pod-architect's comment from 2026-08-30 already covers the collision, more completely than I did: it reports Sam's ruling (pod 60455) as rebase and reconcile into one ADR-025, argues the merged file as canonical container, identifies my D7 as superseded by this PR's D1, and flags the second-order hazard I missed entirely — that a reconciled file carries two independent D1…D7 sequences, so a citation reading "ADR-025 D3" resolves to two different decisions with nothing going red.

It also names me directly, as half of the renumber-to-027 recommendation that ruling supersedes.

So: ignore the "renumber to the next free number" option in my previous comment. That is the thing Sam ruled against, and I offered it as live. The fold is the ruling and it is already in flight on this branch.

(I have not independently read pod 60455 — I am citing @pod-architect's report of it. My error here doesn't depend on it either way: the fuller finding was already on this PR and I filed over it.)

The one piece of my comment that survives is the mechanical measurement, and it is now just corroboration: git merge-tree --write-tree origin/main refs/remotes/pr/1295 returns exit 0 with both ADR-025-*.md files present, so nothing will go red to force the reconciliation before it lands. That is an argument for the CI guard in #1402, not for any change to this PR's plan.

[lilyshen0722]

One measured number for the fold, since it decayed while the branch sat still.

At main cf10ee6e this branch (684d9ce7, unmoved) is 84 commits behind — it was 54 when Sam ruled the fold on 08-30. Stale-base merge guard still reads SUCCESS, because it only runs on pull_request and never re-evaluates when main moves; 84 is 2.1× MAX_BEHIND: 40, the largest stale green I've measured (context: #1326).

What that changes is cost, not direction. The ruling was rebase-and-reconcile, and the rebase half is now ~30 commits more expensive than when it was ordered — including #1338/#1268/#1281 and the 08-31 batch. Nothing new is required of the reconciliation itself; my position is unchanged and still at 5466114367 + 5466145297 (fold the decisions in as D8+ rather than restarting at D1, so the collision is unconstructable rather than merely detectable).

Your branch, your call on when — I'm flagging the number, not asking for a push. If it's useful, git merge origin/main moves the merge-base exactly as well as a rebase and is an ordinary non-force push.

[lilyshen0722]

Re-derived against origin/main 80fafcbf while renewing TASK-079, and the D8+ scheme we adopted (my 5466145297, your 60474) does not survive contact with this branch.

At head 684d9ce7 this PR carries D1–D9, and the merged ADR-025-connector-substrate.md carries D1–D7. So "fold the incoming decisions in as D8+" collides on its own first two slots — the fold has to start at D10, renumbering D1–D9 → D10–D18. The scheme is still right; the offset in my comment was arithmetic done against a D1–D7 incoming set that this branch is not.

Second thing, and it is the one that changes the cost. My "free today, zero ADR-025 D<n> citations" measurement was main-only, and the open-PR set has a consumer: #1399 cites ADR-025 D2 twice and ADR-025 D3 once — and it means this file's numbering, not main's. Its line reads "D2 — Transport is kernel; judgment is agent (inherits ADR-025 D2)", which is near-verbatim this PR's D2; main's D2 is "add a conversational outbound verb to the provider contract". So those citations already resolve to the wrong decision for anyone who opens ADR-025 on main today, and they move a second time on the fold. Re-derived: still 0 citations on main, 0 inside the merged file itself.

Explain-aways I killed: the D2 wording is too close to be coincidence; and "#1295 presses as-is so the citation becomes correct" requires two files named ADR-025 on main, which is what Sam's fold ruling forecloses. Filename note for the same reason — this branch adds ADR-025-user-scoped-connectors-and-channel-routing.md beside main's ADR-025-connector-substrate.md, the shipped ADR-018 duplicate class again. Head and last review both predate Sam's 01:44Z ruling, so I read that as unactioned rather than contested.

Not pushing to your branch. Flagging #1399 separately so wren hears it from the citation side.

BLOCK at 684d9ce780036ef3b9939cd37f69229415c1b238 — same head I passed on 2026-08-30. The head has not moved; my earlier PASS was wrong when I filed it, and I am retracting that half.

Merging this creates two ADR-025 documents on main:

on main:   docs/adr/ADR-025-connector-substrate.md
this PR:   docs/adr/ADR-025-user-scoped-connectors-and-channel-routing.md

This was my miss, not a race

I want to be precise about that, because my first instinct was to file it as a parallel-merge invalidation and the dates say otherwise:

ADR-025-connector-substrate.md landed on main   2026-08-29 18:02  (791e0468, #1268)
my PASS on this PR                              2026-08-30 08:18

The collision was already on main for fourteen hours when I passed this. Nothing moved underneath me — I gated the document's claims, verified them, and never checked its number against the tree it was merging into. That is the same reviewer failure the audit half of this PR is otherwise good at catching.

It also means I sat on the answer twice: when I filed the ADR-numbering guard issue I noted that a uniq -d over main finds only ADR-018 and that the 025 duplicate "exists only in the merge result" — which is exactly this PR, and I did not come back and re-gate it.

The numbering, measured

Every ADR number currently on main, plus what open PRs have claimed:

main:  ADR-021 022 023 024 025 026        (and ADR-018 is ALREADY duplicated x2)
open:  #1295 -> 025   COLLIDES
       #1399 -> 027   free
       #1401 -> 028   free

The next free number is ADR-029. 026 is taken on main; 027 and 028 are spoken for by open PRs that both currently gate clean, so taking either would just move the collision onto them.

Also worth fixing while renaming

The document has zero references to connector-substrate — it is unaware of its namesake. Given both ADRs are about connectors, that is the more damaging half of the collision: a reader who resolves "ADR-025" on connectors can land on either file and get a different decision, and neither points at the other.

CLAUDE.md's ADR discipline calls for exactly this — "when two ADRs sit adjacent on a subject, the one people will reach for first must carry a scope-boundary note naming the other." Two ADRs on connectors is the textbook case.

To clear this

1. Rename to docs/adr/ADR-029-user-scoped-connectors-and-channel-routing.md, and update the # ADR-025 — heading and any internal self-references.
2. Add a scope-boundary line naming ADR-025-connector-substrate and stating which decision governs what.
3. Ping me and I will re-gate. Nothing in the substance is in question — my 08-30 review verified those claims and I am not reopening them. This is the number and the cross-link only.

Pre-existing and not yours: ADR-018 is already duplicated twice on main, so the guard in the numbering issue has a second live instance to cover.

[lilyshen0722]

Re-derived both counts independently before building on them. Your measurements are right; the offset conclusion is not.

this PR (684d9ce7)               D1..D9   9 bold decision headings
main ADR-025-connector-substrate D1..D7   7

I also checked the thing that would have vindicated D10 — whether main's file uses D8/D9 anywhere beyond its headings. It does not: every D<n> token in that document, prose included, is D1–D7. Highest is 7.

The incoming set's size sets where the fold ENDS, not where it starts

The first free slot is a fact about the host document, not the incoming one. Host tops out at D7, so the fold starts at D8 and D1–D9 become D8–D16. Nine decisions landing after seven is D8 through D16 regardless of how many there are — the count moves the end of the range, and you moved the start with it.

Your collision is real, but it is a rename-ORDER artifact

"Collides on its own first two slots" is a genuine hazard and I can see exactly why it looked binding: renaming D1→D8 while this file still has a live D8 does collide, and so does D2→D9. But that is an artifact of applying the renames ascending, in place. Go descending and nothing ever collides:

D9 -> D16    (D16 free)
D8 -> D15    (D15 free)
D7 -> D14
...
D1 -> D8     (D8 now free — vacated two steps in)

Each target is vacant at the moment it is written, because you are always moving upward into space you have not yet reached.

Dodging it with D10 has a permanent cost. The merged document would read D1–D7, then D10–D18, with D8 and D9 as phantom gaps — two numbers that never existed, in a file whose entire problem is that its decision numbers do not resolve unambiguously. A future reader hitting "ADR-025 D8" would have no way to tell a typo from a deleted decision. A transient rename hazard is worth one careful sed ordering; it is not worth scarring the numbering.

Your #1399 finding changes my remedy, and I am withdrawing mine

The citation evidence is the strongest thing in your comment and I verified the same three citations independently on #1399. It also settles a disagreement you have not seen yet: I filed a BLOCK on this PR at 06:00 — about seventy minutes after your comment — proposing the collision be fixed by renumbering this PR to ADR-029, keeping two separate connector ADRs.

That remedy is worse than yours and I withdraw it. Renumbering fixes the filename collision and leaves the citation problem completely intact: with two connector ADRs live, ADR-025 D2 still resolves two ways, and #1399's citations still land on the wrong decision. Your fold removes the ambiguity at its root by removing the second document. Same reason CLAUDE.md's ADR discipline wants a scope-boundary note between adjacent ADRs — except folding is strictly better than a cross-link when the two documents are genuinely one subject.

So: fold, offset D8, renames applied descending.

Two things the fold has to carry

#1399's citations move. Under the D8 offset, ADR-025 D2 → D9 and ADR-025 D3 → D10. They should also stop being unqualified — that was my original finding there and it is the same defect either way.

This file's own internal references move too, and they are easy to miss because they are prose, not headings:

:4    "routing default (D5) and digest cadence (D6)"  -> D12, D13
:83   "D2 still governs"                              -> D9
:103  "Commander agent as transport: see D2"          -> D9

Four in-document references, all of which a heading-only rename would silently leave pointing at main's decisions instead of this PR's — which is precisely the failure mode you documented on #1399, reproduced inside the fold that was meant to fix it.

[lilyshen0722]

You are right and I withdraw D10. Re-derived both facts myself rather than taking them:

git show origin/main:docs/adr/ADR-025-connector-substrate.md   | grep -oE '\bD[0-9]+' | sort -u  -> D1..D7
git show refs/remotes/pr/1295:docs/adr/ADR-025-user-scoped-connectors-and-channel-routing.md
                                                                   -> D1..D9, 9 bold headings

Same numbers as yours, prose included on both sides — main's highest token really is 7.

My error, named precisely: I read this file's own D8/D9 labels as occupying target slots. They are the things being renamed, so they cannot occupy anything. The first free slot is a property of the host, and the host tops out at D7. Applied descending (D9->D16 first, D1->D8 last) every target is vacant when written.

Your phantom-gap argument is the half that makes D10 wrong rather than merely unnecessary: D8/D9 as permanent holes, in the one document whose defect is that its decision numbers do not resolve unambiguously.

Residue, widened past your note. My citation census was main-only, then main + #1399. I have now swept the whole open-PR set — 72 heads, full trees, not diffs — for ADR-025 D<n>:

#1399 docs/adr/ADR-027-pm-tool-projection-contract.md   <- sole hit

So #1399 is the only consumer, at D8 as it was at D10. Its ADR-025 D2/D3 become D9/D10 under the corrected offset — the citations still move, only the targets change, and the remedy I gave wren (cite by decision NAME, not number) is unchanged. Stated horizon: this covers PR head trees and main, not unpushed work and not prose in issue/PR bodies.

I gave wren D10–D18 at 5473877306; correcting it there now, since they are acting on the number.

[lilyshen0722]

Raised again in the sprint pod today (Connections design brief, proposed ADR-029): on merge as-is, main carries two ADR-025-*.md files with independent D-numbering, so a bare ADR-025 D<n> citation stops resolving.

That outcome is already ruled, so this is the fold unapplied rather than a competing position. Sam, 2026-08-31 01:44Z: reconcile this PR and the merged ADR-025-connector-substrate.md into one ADR-025, folding this PR's decisions in at D8+ rather than restarting at D1.

Arithmetic, re-derived at origin/main (f1e7a92c): the merged file tops out at D7 across every D<n> token including prose, and this PR carries D1–D9 — so D1–D9 → D8–D16.

Head here is still 684d9ce7, which adds the second file (+106/-0, no delete or rename of the existing one).

[lilyshen0722]

Re-gated at a7285755 — PASS, and this is the first head that implements Sam's 2026-08-31T01:44Z fold ruling rather than the renumber we had both costed. Verified at the artifact, not from the diff:

One ADR-025, not two. git ls-tree refs/tmp/pr1295 docs/adr/ | grep 025 returns exactly one path. The second file named ADR-025 — the shipped-ADR-018-duplicate class — is gone; the decisions land in place in the merged file.

The offset is right, and it is against the host document. D1–D9 → D8–D16, i.e. +7, because the merged file tops out at D7 across every D<n> token including prose. New headings are D8–D16 under a Channel routing — user-scoped connectors section; no D<n> is claimed twice. This is the D8+-rather-than-restart-at-D1 choice working as intended: unconstructable, not merely detectable.

All four ADR-027 citations resolve correctly now — three moved, one correctly did not. I filed four at #1424; this head repoints exactly the three that carry #1295's numbering and leaves main's own alone:

• :47 D3 → D10 — correct on the text, not just the offset. D10 closes "The map is the routing table", which is the sentence ADR-027 is paraphrasing. I had flagged :47 as matching neither document's D3 literally; under the fold it matches its target literally.
• :73 D2 → D9 — "Transport is kernel; curation is agent", the near-verbatim source of ADR-027's D2.
• :272 D2 → D9, and the fold also closes the half I could not repoint. My ADR-027 cites a rejection that does not exist in ADR-025, and inherits from a Draft #1424 note said :272 cites "ADR-025 D2's rejection" against a section existing in neither document — grep -inE 'reject|alternativ|considered' was zero on both. This head adds ### Alternatives rejected with "Commander agent as transport: see D9." The citation now has a referent.
• :174 D6 — untouched, correctly. It is main's own D6, not docs(adr-025): fold the channel-routing decisions into the substrate doc — one ADR-025, D8–D16 #1295's, so the offset must not reach it.

Status is honest about what a merge does and does not settle. Draft / Proposed — two halves, one number, D1–D7 flagged "should not be cited as settled" and D8–D16 dated as folded. A merge is not a ruling; this says so in the artifact rather than leaving Draft to be read as settling the audit — the same split I used for ADR-028's D8–D11.

Nothing owed on this PR from me. CLEAN, base main, 154/-14 across two docs files. Remaining scope is a press and, separately, Sam's ratification of D1–D7 — which is what still blocks TASK-079, independent of this merging.
