- Line 13: Reconcile the open bug-PR count in the inventory summary with the
table and the later wp1 total: either update the count to match the 25 non-#2134

disposition claim.

historical snapshot and add a corrected table.

The opencode-free header direction is useful, but I am requesting changes on the current head because the branch is not a focused or current merge unit.
Two blockers remain:
4890c1c4ais 30 commits behind the currentdevhead. The green checks validate that stale mixed head, not a branch based on the current integration state. Rebase onto the latestdevand rerun exact-head CI.- The PR title and core implementation concern registry header propagation, but the 17-file diff also carries the nine
devlog/_plan/260820_bug_pr_backlog_consolidation/*files plus the unrelated subagent-roster changes insrc/server/management/agent-settings-routes.ts,tests/combo-management-api.test.ts, andtests/subagent-roster-retention.test.ts. Remove those unrelated commits/files. The reviewable unit should contain only the registry header contract, its inference/discovery propagation, and the directly corresponding tests.
After the branch is focused, rebased, and exact-head CI is green, this remains a reasonable merge candidate. The current CI result is not sufficient evidence for the cleaned branch because it covers materially different ancestry and scope.
…claims opencode-free sent no User-Agent, so Zen saw the bare runtime default (Bun/x.y.z) and rate-limited it harder than a client that identifies itself. Adds "User-Agent: opencode" alongside the existing x-opencode-client: desktop marker. The value is deliberately unversioned. OmniRoute, an independent open-source broker against the same Zen upstream, defaults to exactly this pair and reached it by retreating from its own earlier opencode-cli/1.0.0 pin: a pinned version is a claim about an install we do not have, and it goes stale on the vendor's schedule. The registry edit alone would have shipped to nobody. staticHeaders is documented as merged into every upstream request, but it was only ever copied at seed time, so any config written before a header existed -- or carrying any header of its own -- never received it. routedProviderConfig and buildModelsRequest now fill registry static headers beneath user headers, matched case-insensitively so an override replaces rather than duplicates: spreading "User-Agent" over a user's "user-agent" leaves both keys, which Headers serializes as one comma-joined value. Model discovery gets the same treatment because a provider identified as opencode when it completes but anonymous when it lists its own models reads as two different clients to a rate limiter.

Approved for this layer only, relative to base codex/fix-subagent-roster-truncation. The current layer is now focused: runtime merge of registry static headers, matching discovery behavior, and the directly corresponding tests. I verified that the only current registry staticHeaders row is opencode-free, user headers win case-insensitively, and the resolved headers reach both inference and /models. The exact stack-tip focused run passed, including all opencode-free cases.
This approval does not approve or merge the parent #2134 devlog diff. Merge/retarget bottom-up only after the parent blocker is resolved, and preserve exact-head CI after retargeting to dev.

Summary
Absorbs #2067 by @waw4303, and fixes the delivery gap that would have made it a no-op for existing installs.
The reported defect.
opencode-freesends noUser-Agent, so Zen sees the bare Bun runtime default and rate-limits it harder than a client that identifies itself. This addsUser-Agent: opencodebeside the existingx-opencode-client: desktopmarker — the revised shape @waw4303 landed on, not theopencode-cli/1.0.0pin the PR originally proposed.Why unversioned. A pinned CLI version is a claim about an install we do not have, and it goes stale on the vendor's schedule rather than ours. OmniRoute — an independent open-source broker against the same Zen upstream — defaults to exactly this pair (
userAgent: "opencode",client: "desktop") inopen-sse/executors/opencode.ts, and arrived there by deliberately retreating from its own earlieropencode-cli/1.0.0pin. That is corroboration from a project solving the identical problem, not an authority we are bound by.The part that was missing. The registry edit alone would have shipped to nobody.
staticHeadersis documented as "merged into every upstream request for this provider" (registry.ts), but it was only ever copied at seed time:providerConfigSeedwrites the block once,enrichProviderFromCatalogfills it only when the entire block is absent, and nothing merged it at request time. Verified directly againstroutedProviderConfig("opencode-free", ...):routed.headersbefore this PRundefined{x-opencode-client: desktop}{user-agent: custom-agent}So every existing
opencode-freeuser would have kept the old fingerprint forever.routedProviderConfigandbuildModelsRequestnow fill registry static headers beneath user headers.Case-insensitive on purpose. HTTP header names are case-insensitive; object keys are not. Spreading a registry
User-Agentover a user'suser-agentleaves both keys, whichHeadersserializes as one comma-joined value ("custom-agent, opencode") — a corrupted request rather than an override. The user's spelling and value both win; the registry only fills names the user has not claimed.Model discovery too. A provider identified as
opencodewhen it completes but anonymous when it lists its own models reads as two different clients to a rate limiter, sobuildModelsRequestuses the same merge.opencode-freeis currently the only registry row withstaticHeaders, so the router change's blast radius today is exactly this provider. Deliberately not copied from OmniRoute:x-opencode-project,x-opencode-request, andx-opencode-session. None is needed for the reported failure, and a conversation-derived session id is a privacy-relevant change that needs its own evidence.Closes #2067.
Verification
bun run typecheck— clean.bun test --isolate tests/opencode-free-provider.test.ts— 18 pass / 0 fail.router.ts+oauth/index.ts(keeping the registry header) fails exactly the 5 new delivery tests: 13 pass / 5 fail. Reverting only the registry header fails the suite at load. Neither test is vacuous.bun run test(full suite) — 13519 pass / 10 skip / 0 fail across 856 files.bun run privacy:scan— passed.tests/management-provider-validation.test.ts"provider PATCH clear keeps registry static headers" updated for the two-header registry set — 72 pass / 0 fail.Checklist
The header carries no user data and no credential; an operator can still override either value through the provider headers API, and that override now wins case-insensitively instead of duplicating.
