Cell / Jurisdiction Routing Infrastructure Map (github.com/entireio/cli)

Repo state note: working tree is clean on main (HEAD 4398a44c1). PR 1592 is NOT merged here. Current main already contains the experts cell-routing stack (experts_cell_target.go, api_client.go, the isActiveMirror helper). PR 1592's net-new is the activity/recap wiring plus a few cell_data_api.go hardening fixes (details in §3). The gh pr diff for experts_cell_target.go is a stale-base artifact — that refactor already landed on main.

Layer overview (bottom to top)

1. cmd/entire/cli/auth/cell_data_api.go — the token-exchange + cell-resolution core

This is the single source of truth for "which cell host does a data-plane request dial, and what token does it carry."

Entry point

1

func NewEntireAPICellClient(ctx context.Context, insecureHTTP bool, target *CellTarget) (*api.Client, error)  // :99

Steps (:99–:134):

1. resolveStoredCellSubject (:205) — deliberately ignores ENTIRE_TOKEN; resolves the active stored login context, discovers trusted login servers via /.well-known/entire-api.json, and refreshes the login JWT. Returns a cellSubject{loginJWT, discoveredCore, dataOrigin, httpClient} (:183).
2. targetJurisdiction (:300) → resolveJurisdiction (:314): the CellTarget.Jurisdiction override, else the home_jurisdiction JWT claim. Validated against jurisdictionLabelPattern = ^[a-z0-9]([a-z0-9-]{0,38}[a-z0-9])?$ (:43) so the claim can only name a sibling DNS label, never inject host/scheme.
3. jurisdictionCoreURL (:432) — the entire-core origin to run the exchange at. Precedence: loopback discovered core verbatim → ENTIRE_CORE_BASE_URL_TEMPLATE → https://{jurisdiction}.auth.<family> → discovered core. <family> (entire.io / partial.to) comes from environmentFamily (:397).
4. resolveTargetCellBaseURL (:334) — the cell-host decision (precedence doc at :91):

• target.BaseURL set → use it verbatim (the repo-scoped path).
  • dataOrigin is not a BFF (host contains .api. or is loopback, isBFFOrigin``:351) → keep verbatim.
  • else BFF/apex → resolveCellAPIBaseURL home-jurisdiction fallback.

5. jurisdictionAudience (:411) — the aud (https://{jurisdiction}.<family>), mirrors the BFF's buildAudience.
6. exchangeJurisdictionToken (:562) — RFC 8693 exchange: httputil.TokenExchangeForm(loginJWT, audience, scope=openid) POSTed via httputil.PostOAuthToken. JurisdictionIdentityScope = "openid" (:30) — identity semantics only, authorization is per-request server-side (COR-666).
7. Returns api.NewClientWithBaseURL(token, cellBaseURL).

Jurisdiction → cell host mapping (aws-us-east-2.api.entire.io)

Two independent resolvers produce the cell apiUrl:

• Repo-scoped (preferred): CLI resolves it upfront in experts_cell_target.go (§2) and passes CellTarget.BaseURL.
• Home-jurisdiction fallback:resolveCellAPIBaseURL (:508) hand-parses GET /api/v1/clusters (clustersAPIPath``:33), filters rows by jurisdiction, prefers isDefault, returns apiUrl. It hand-rolls the HTTP call rather than reusing coreapi.ListClusters to avoid an import cycle (coreapi imports auth) — noted at :502–:507.

home_jurisdiction claim reader

1

func HomeJurisdictionFromLoginJWT(loginJWT string) (string, error)  // :478

Decodes JWT payload without signature verification (routing only; server re-verifies). Shared with git-remote-entire. Returns "" (no error) when absent.

CellTarget

1
2
3
4

type CellTarget struct {           // :51
    BaseURL      string  // e.g. https://aws-eu-west-1.api.entire.io
    Jurisdiction string  // drives token audience + exchange core
}

ErrNoCellForJurisdiction

Does not exist on current main. Today resolveCellAPIBaseURL returns plain fmt.Errorf strings (:548, :550). PR 1592 introduces the sentinel (§3).

Other entry point

1

func JurisdictionToken(ctx, insecureHTTP bool, jurisdiction string) (string, error)  // :154

Raw-token variant used by entire auth token --jurisdiction; does honour ENTIRE_TOKEN (via resolveCellSubject``:195), unlike NewEntireAPICellClient.

2. Experts command — cell targeting

Call chain: experts_cmd.go runExperts → newExpertsAPIClient (:32) → NewAuthenticatedEntireAPICellClient (api_client.go:62) → resolveExpertsCellTarget (experts_cell_target.go:53) → auth.NewEntireAPICellClient.

1
2

func NewAuthenticatedEntireAPICellClient(ctx context.Context, insecureHTTP bool, fullName, ulid string) (*api.Client, error)  // api_client.go:62
func resolveExpertsCellTarget(ctx context.Context, fullName, ulid string) *auth.CellTarget                                   // experts_cell_target.go:53

resolveExpertsCellTarget (5s deadline, expertsCellResolveTimeout``:18):

1. resolveRepoClusterHost (:93): ULID → coreapi.GetRepo().ClusterHost; owner/repo → listMirrorsForRepo → distinctActiveClusterHosts.
2. c.ListClusters → matchClusterByHost (:168, matches on PublicUrl host) → cluster.ApiUrl + cluster.Jurisdiction → CellTarget.

Single target only — no fan-out.resolveRepoClusterHost:113 bails to nil (home-jurisdiction fallback) when len(hosts) != 1, i.e. a repo mirrored in multiple regions is explicitly treated as ambiguous and not fanned out (:117). Every failure path returns nil → NewEntireAPICellClient falls back to home-jurisdiction routing (best-effort contract, :39–:44).

runExperts (experts_cmd.go:276) selects one repo identity (ULID or owner/repo) and gets one client (:282). Cross-region misroute is handled reactively: a 404 with "region" in the body prints a region hint (:316–:319).

1
2

func distinctActiveClusterHosts(mirrors []coreapi.Mirror) []string  // :143
func isActiveMirror(m coreapi.Mirror) bool                          // :129  (archived / failed / suspended excluded)

3. PR 1592 (entireio/cli) — what it adds

Theme: route activity/recap through the same cell client as experts, with a data-API fallback; harden cell_data_api.go.

New file cmd/entire/cli/entireapi_client.go (shared client seam):

• runAuthenticatedActivityAPI(ctx, errW, insecureHTTP, fn) — tries auth.NewEntireAPICellClient(ctx, insecureHTTP, nil) (home cell); any error → logCellClientFallback + runAuthenticatedDataAPI. Both backends serve /me/*, so fn is backend-agnostic.
• logCellClientFallback — silent for ErrNoCellForJurisdiction / ErrNotLoggedIn (normal during rollout), else debug-logs.
• forgeToMirrorProvider(forge) — gh/github → github, else not-ok (GitHub-only today).
• currentRepoID(ctx) — resolves origin remote → mirror → repo ULID (for /me/recap?repo=); "" on any failure.
• firstActiveRepoID(mirrors) — first isActiveMirror placement's MirrorId.

activity_cmd.go:runActivity switches runAuthenticatedDataAPI → runAuthenticatedActivityAPI.

recap.go:newRecapClient now returns (*api.Client, repoSlug string, error) — prefers the cell client (currentRepoID = ULID) and falls back to data API (currentRepoSlug = owner/repo slug), tolerating not-logged-in.

cell_data_api.go hardening:

• Adds var ErrNoCellForJurisdiction sentinel; resolveCellAPIBaseURL wraps it with %w (so errors.Is works for the fallback).
• Fallback lists the cluster catalog against selected.CoreURL (the login core that signed loginJWT), not the templated jurisdiction core — renames param coreURL→listCoreURL; the exchange still uses coreURL.
• targetJurisdiction case-folds the JWT claim (strings.ToLower(TrimSpace)) before the strict label check, so an uppercase home_jurisdiction routes instead of hard-failing.

Note: the PR diff also shows adding isActiveMirror / refactoring distinctActiveClusterHosts in experts_cell_target.go, but those already exist on main — a stale-base overlap, not net-new.

4. Multi-cell fan-out audit

There is no data-plane fan-out anywhere in the CLI today. Every path resolves exactly one target cell:

• distinctActiveClusterHosts (experts_cell_target.go:143) is the only place that computes the set of clusters a repo lives on — and its sole consumer (resolveRepoClusterHost:112) rejectslen != 1.
• selectCloneTarget (repo_clone.go:211) enumerates a repo's placements but picks one (via --cluster or interactive prompt) — clone, not query.
• The mirror-create wizard (repo_mirror_create_wizard.go) iterates the cluster catalog only to let the user choose a placement.
• No groupReposByCell, no per-cluster query iteration, no "run request X against every cell" loop exists. coreapi.ListRepos (internal/coreapi/oas_client_gen.go:4900) is a single control-plane call.

The only transparent cross-region mechanism is at the control-plane layer: coreapi.New() (internal/coreapi/client.go:35) wires newCrossJurisHTTPClient (cross_juris_transport.go), whose transport follows 421 cross-jurisdiction redirects and does the RFC 8693 exchange a foreign core requires. So control-plane reads (repo/mirror/cluster) work across regions from a home login — but that is redirect-follow, not client-side fan-out, and it applies only to coreapi, not to entire-api cell data.

5. Repo → cell/cluster association (CLI's view)

• Cluster catalog (coreapi.Cluster, oas_schemas_gen.go:~655): ApiUrl OptString (cell data host), Jurisdiction string, PublicUrl string (git/public host). ListClusters is the authoritative jurisdiction→apiUrl source.
• Repo placement: coreapi.Repo.ClusterHost OptString (:6493) for the ULID path; coreapi.Mirror.ClusterHost (per placement) for the owner/repo path.
• listMirrorsForRepo (repo_clone.go:180): lists all placements of a repo across clusters (server filters by provider+owner; repo matched client-side). Used by experts targeting, api_cmd.go``{repo_id} expansion, PR 1592's currentRepoID, and clone.
• Join: matchClusterByHost (experts_cell_target.go:168) links a placement's ClusterHost to a catalog cluster via PublicUrl host, yielding ApiUrl + Jurisdiction.
• Default when unplaced: defaultClusterHost = "aws-us-east-2.entire.io" (repo_mirror.go:55).

Single source of truth & gaps

"Which cell does request X go to?"

• Repo-scoped data-plane (experts, and recap-with-repo under PR 1592):resolveExpertsCellTarget (CLI layer) → CellTarget → NewEntireAPICellClient. Authoritative catalog = coreapi.ListClusters.
• Personal/home data-plane (activity, recap personal side):home_jurisdiction JWT claim → resolveCellAPIBaseURL fallback.
• Control-plane: always the home core; cross-region handled by 421-follow transport.

Duplication / gaps observed:

1. Two cluster-catalog parsers.resolveCellAPIBaseURL (auth, cell_data_api.go:508) hand-parses GET /api/v1/clusters, duplicating coreapi.ListClusters — forced by the auth↔coreapi import cycle. The repo-scoped path sidesteps it by resolving in the CLI layer; the home-fallback cannot. This is the main structural wart.
2. Repo-ID resolution duplicated 3×:resolveCurrentRepoID (api_cmd.go:194), resolveExpertsRepoID (experts_cmd.go:387), and PR 1592's currentRepoID/firstActiveRepoID — all "list mirrors → first active → MirrorId." PR 1592 partially consolidates via the shared isActiveMirror, but the three call sites remain.
3. Multi-region repos are a hard gap, not a feature. Any repo mirrored across >1 cluster silently degrades to home-jurisdiction routing and relies on a reactive 404-region hint. No fan-out, no "ask each cell." If cross-region querying is the goal, this is the layer to build on — distinctActiveClusterHosts already computes the needed host set but its callers throw it away.
4. ENTIRE_TOKEN asymmetry:NewEntireAPICellClient ignores it; JurisdictionToken honours it (cell_data_api.go:100, :154). Intentional but a subtle footgun for anyone adding cell commands.

Second report is in. The CLI map confirms the picture: today there is exactly one cell per request everywhere — experts resolves a single repo → single cell, #1592 adds home-cell routing with data-API fallback, and no data-plane fan-out exists anywhere. It also surfaced a structural wart (the auth package hand-parses /api/v1/clusters because of an auth↔coreapi import cycle) and three duplicated repo-ID resolvers. One agent left: the entiredb/entire-api backend model, which should tell us what invariants a shared fan-out layer can rely on (repo↔cell placement, token audience scope, and how the BFF does its fan-out). I'll write up the recommendation when it lands.

1w ago·2m·2 calls

All three investigations are done, and I verified the one suspicious join myself. Here's the synthesis.

TLDR

Yes — I'd build the foundation first, but the "foundation" is a modest extraction, not a framework. #1592 is already part of that foundation and should land first. #1616 should then be reworked on top of a small shared cell-routing package before merge: it currently inlines ~300 lines of generic multi-cell orchestration under codeSearch-prefixed names, mints tokens wastefully (once per cell instead of once per jurisdiction), and joins the repo index to the cluster catalog on a fragile key. Since it's gated behind ENTIRE_CODE_SEARCH=1 and has had no human review yet, now is the cheapest moment to fix the shape.

Why the timing question is real: three routing shapes are converging

The backend model (entiredb + entire-api) defines exactly three request shapes, and the BFF (entire.io/api/src) already has a named helper for each:

1. Repo-scoped → one cell (BFF resolve-cell.ts): a placement lives in exactly one cell; resolve it, mint a jurisdiction token, call that cell. The CLI's version is the experts path (resolveExpertsCellTarget in experts_cell_target.go).
2. User-scoped /me → home cell, never fan-out (BFF resolve-home.ts): activity is forwarded into the user's home region, so /me is a single point-to-point call routed by the home_jurisdiction JWT claim. That's what #1592 adds (entireapi_client.go, ErrNoCellForJurisdiction, the case-folded claim).
3. Repo-set queries → fan out to every hosting cell, merge client-side (BFF code-search.ts): no server-side aggregator exists anywhere — core returns catalogs, cells are strictly local. #1616 is the CLI's first instance of this shape.

The CLI is growing these one command at a time, each with its own seams. #1616 would make it three commands, three sets of plumbing.

Concrete problems with merging #1616 as-is

1. The generic layer is inlined and search-named.groupReposByCell, resolveRepoFilters, the ListRepos→ListClusters→CellTarget resolution, the WaitGroup fan-out with per-cell timeouts, and the partial-failure tracking (FailedJurisdictions) are all in search_cmd.go — none of it is search-specific. The next fan-out command (experts natural-language query is an obvious candidate: cells return 503 for it today precisely because it needs the search index) copies or refactors it. It also duplicates experts' patterns with different choices: a second coreClient interface+seam, different timeout constants, and no placement/active-mirror filtering.

2. Token minting ignores the key backend invariant. Identity tokens are per-jurisdiction, not per-cell — every cell in a jurisdiction accepts the same token. #1616 calls auth.NewEntireAPICellClient once per cell, and each call independently re-runs discovery, login-JWT refresh, and the RFC 8693 exchange. The BFF single-flights and caches one token per jurisdiction. With N cells that's N× redundant auth round trips per search, growing with every future fan-out command.

3. The catalog join is fragile — verified. #1616 groups repos by RepoIndexEntry.Cell (physical cell, e.g. aws-us-east-2) but looks that value up in a map keyed by Cluster.Slug (slugToCluster[cells[i].cell], diff line ~576). The cluster catalog response doesn't expose a cell field at all — RepoIndexEntry carries ClusterSlug for exactly this join, and #1616 doesn't use it. Today slug and cell often coincide, so a mismatch degrades to the jurisdiction fallback (right region, but it triggers a hand-rolled per-cell cluster-catalog re-fetch inside auth) rather than misrouting — but it's a silent behavioral cliff. This is now the third distinct join key against the same catalog: experts joins by PublicUrl host, #1616 by slug-as-cell, the auth fallback by jurisdiction.

4. Existing warts get a third copy instead of a fix.resolveCellAPIBaseURL in auth/cell_data_api.go:508 already hand-parses GET /api/v1/clusters because of the auth↔coreapi import cycle, and repo-ID resolution exists three times (api_cmd.go, experts_cmd.go, #1592's currentRepoID).

What the foundation should be

A small package (say cmd/entire/cli/cellrouting) with three entry points mirroring the BFF's helpers, built from what already exists:

• RepoCell(ctx, fullName, ulid) *auth.CellTarget — lift resolveExpertsCellTarget out of experts naming.
• HomeCell(ctx) — #1592's entireapi_client.go logic, essentially as-is.
• CellsFor(ctx, repoFilter) []CellGroup + FanOut(ctx, groups, timeout, fn) — extracted from #1616's searchAllCells/searchCell, with the join fixed to ClusterSlug↔Slug, and one coreClient seam shared with experts. Merge semantics stay per-command.
• Per-jurisdiction token cache inside or in front of NewEntireAPICellClient: resolve the stored subject once, exchange once per jurisdiction, reuse across cells in a fan-out.

Deferrable: breaking the auth↔coreapi cycle so there's one cluster-catalog parser, and consolidating the three repo-ID resolvers.

Suggested sequencing

1. Merge #1592 now. It's small, it establishes the home-cell shape and ErrNoCellForJurisdiction, and the foundation builds on it rather than replacing it.
2. Extract the routing package (mostly moving code from #1616's diff plus experts), with the per-jurisdiction token cache and the ClusterSlug join fix.
3. Rebase #1616 onto it. The search-specific parts — the codesearch client package, merge/sort/dedup semantics, output rendering, flag handling — are genuinely good and carry over unchanged; its ~940 lines of tests mostly test logic that moves rather than dies.

The counterargument — merge behind the env gate, refactor later — is defensible, but weak here: the PR has had no human review of the orchestration (only two stale Copilot nits), the extraction is cheap while the code is fresh, and gated code has a way of calcifying into the pattern the next command copies.

the issue is that 1592 is currently red and has open comments, so merging is not straight forward, so let's fix that and build the routing package extraction on top?

All caught up — the whole stack is now either merged or waiting only on human review:

Done since we started:

• #1640 (red-main fix) — merged. Main is green again.
• #1592 (activity/recap → home-cell client) — merged, with all five bot findings fixed.
• #1641 (the cell-routing foundation, now based directly on main) — CI fully green, and all five of its bot findings are fixed and replied to: tokenFor now uses per-jurisdiction mint slots so no lock is held across the network exchange, the fan-out catalog lookup got the cellResolveTimeout bound, resolveCellBaseURLs refuses to set a baseURL without a jurisdiction (which would have dialed a foreign cell with a home token), and empty-cell index entries group per-jurisdiction instead of collapsing into one mixed group.
• #1616 coordination — I posted a comment on evis's PR pointing at #1641 and sketching the rebase: the codesearch client, merge/dedup semantics, and rendering carry over unchanged; the inline orchestration collapses onto groupReposByCell/resolveCellBaseURLs/fanOutCells.

One thing worth flagging from #1616's history: it actually had a commit that correctly switched the catalog join to ClusterSlug, which a later commit reverted citing BFF parity — but the BFF templates cell URLs from the cell name rather than doing a catalog lookup, so the parity argument doesn't apply to a Slug-keyed lookup. The comment spells that out so the join doesn't flip back again; #1641 pins it with a slug≠cell test.

The only remaining step is human: #1641 needs a code-owner review from entireio/cli-maintainers (you can't self-approve, and the ruleset blocks admin bypass). Once it lands, #1616 can rebase — I'm happy to do that rebase or review it when the time comes.

1641 had a review comment with the last approval, that's resolved?

Memory updated too. Once evisdren re-approves, #1641 merges and #1616 can rebase onto it — I've already left the rebase guidance on that PR.

ffc362dcli/auth: make the two-tier mint locking contract explicit in comments\ \ Review nit on #1641: CellClientFactory.mu's comment said "never held\ across I/O" while mintSlot.mu is deliberately held across the exchange\ (that's the single-flight).
