fix(tui): show provider ownership in Recent and Favorites

[PierrunoYT]

Summary

Recent and Favorites can contain models from different saved providers, but their rows previously displayed only the model name. Selecting an indistinguishable row could switch from a subscription provider to a metered API provider without showing that ownership before selection.

• Prefix rows in these mixed-provider groups with the saved OwnerProvider, including custom profile names.
• Use the same display label for rendering and picker sizing so the prefix is included in width calculations.
• Keep provider-grouped rows, model values, filtering, and selection behavior unchanged.

Linked issue

Fixes #840

Verification

The new regression tests failed on the original renderer, including:

group=Recent selected=false: row = "  GPT-5.6 ...", want "chatgpt · GPT-5.6"

They now cover Recent/Favorites, selected/unselected rows, distinct owners for the same model, custom profile names, ownerless fallback rows, and width calculation. The existing provider-group test also checks that ownership is not repeated unnecessarily.

Passed locally on Linux after rebasing onto upstream main:

• make fmt-check
• go build ./...
• go vet ./...
• GIT_CONFIG_COUNT=1 GIT_CONFIG_KEY_0=commit.gpgsign GIT_CONFIG_VALUE_0=false go test ./...
• go run ./cmd/zero-release build
• go run ./cmd/zero-release smoke
• make vulncheck
• git diff HEAD --check

make lint-static reports four pre-existing advisory findings in untouched upstream files: QF1001 in internal/installtest/workflow_permissions_test.go:20, and QF1008 in internal/proxydial/proxydial.go:67,72 and internal/tools/web_fetch.go:315. None are in the changed files.

The test-only Git environment override disables inherited commit signing for disposable fixture repositories; without it, the orb reports No signing key is available for this commit. No Git configuration was changed. This change does not affect concurrency.

UI preview

Inspected monochrome preview of the actual picker renderer output, showing distinguishable Recent rows and provider ownership in Favorites. This is a rendered fixture, not a live provider session.

Checklist

• The linked issue already has the issue-approved label.
• go build ./..., go vet ./..., and go test ./... pass locally.
• gofmt clean.
• Tests added/updated for the change (and run under -race where relevant).
• UI changes include screenshots or a short recording where possible.

Summary by CodeRabbit

• New Features
  • Recent and Favorites rows show the provider that will be used when selected, alongside the model name. Favorites retain their * marker, and rows without a resolvable provider show the active provider.
  • Provider and model labels adapt to the available space: long names are truncated or displayed on separate lines, and the overlay sizes to fit. When the selected provider’s full numbered label is not visible in its row, it appears below.
• Bug Fixes
  • Selecting a model with an outdated provider association applies it to the active provider; valid associations continue to select their provider and model together.

Walkthrough

Recent and Favorites rows now show the provider that selection will use. Selection switches to a saved provider when the row resolves to one. Unresolved owners use the active provider. Row labels can wrap, and overlay sizing uses the formatted label.

Changes

Model Picker Row Labels

Layer / File(s)	Summary
Resolve the provider used by each row internal/tui/picker.go, internal/tui/model.go, internal/tui/picker_test.go	Recent and Favorites items receive the provider used for selection. Unresolved owners use the active provider. Tests cover fallback and resolvable providers, including displayed destinations.
Render and measure picker row labels internal/tui/view.go, internal/tui/rendering_lime_test.go	Rows show the owner inline or on a separate line, capped at 20 cells. Favorite rows retain the * marker. Overlay sizing uses the formatted label, and selected rows can show a numbered owner cue. Tests cover truncation, narrow widths, and missing owner data.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix · Severity of issue fixed: Medium

Suggested reviewers: anandh8x, jatmn, euxaristia

Merge Risk: 🔵 Low · up to 26c12

On narrow terminals, wrapped entries can be clipped or mouse clicks can select a different provider or model. Keyboard navigation remains a workaround, so this is a localized UI risk.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 26c12

The change makes the intended provider visible before selection and does not appear to add a way to select an unsaved provider. No new security issue was established, though review coverage is incomplete.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The changed reachability is the local picker’s presentation and existing saved-provider selection path, not a new externally callable entrypoint.

Trust Boundaries and Controls

• observed — Saved-profile lookup remains the control on cross-provider selection. Tests cover fallback when a recorded provider has been removed and selection of the provider identified by an abbreviated cue.

This does what #840 asks. I checked it against the real picker, not just the hand-built rows in the tests: assembleModelPickerItems uses exactly the Recent and Favorites group names the label keys on, and every Recent and catalog row gets OwnerProvider from the saved profile name, so a favorite surfaced from another provider's catalog shows whose it is too.

The tests hold up. Dropping the prefix fails TestModelPickerRowShowsOwnerInMixedGroups, prefixing every group fails TestModelPickerRowOmitsProviderTag with the provider repeated under its own section header, and sizing the overlay from the bare label fails TestModelPickerWidthIncludesOwner with the row clipped.

internal/tui passes here on Windows and CI is 9/9. Approving.

I found two issues to address before this is ready.

Merge readiness

The captured live main is 99721c762f37cd43ac511007a5f51d1846df959e, the PR head is a45a8f91b322b315d0fff0cc8d1235ece82eff0a, and GitHub reports the branch conflict-free (mergeable: MERGEABLE). All ten reported checks pass. GitHub nevertheless reports mergeStateStatus: BLOCKED; the API evidence does not identify which branch rule remains unsatisfied. Confirm that rule after the findings are addressed. No rebase or release-metadata drift is indicated by the captured target SHA.

Findings

🟠 P1 — Make the displayed owner match the provider Enter will use

📍 Where: internal/tui/view.go:1168-1170, for both mixed-provider groups.

💥 What fails: Rename or remove an inactive saved provider after using one of its models, then open /model while a different provider is active. The persisted Recent entry keeps the old provider name. The new row can say chatgpt · GPT-5.6, but Enter resolves no saved chatgpt profile and applies the model to the active provider instead. If the active provider is a metered generic gateway, it can accept that model ID. Favoriting that historical model can put the same false owner in Favorites. The label now promises precisely the account the user will not use.

🔎 Root cause: The new label trusts OwnerProvider from history as the selection destination. Existing selection code explicitly treats an unresolved historical owner as a fallback to the active provider. Provider rename/removal does not rewrite recent history, so the two identities can diverge.

📜 Stated contract:

“Provider-grouped rows already get this for free via the group header; Recent/Favorites should not lose it.” — approved issue #840, referring to visibility of the owning provider before selection.

🏷️ Attribution: PR-worsened. At merge base and live main, this same stale row showed only the model and Enter used the active provider. The PR head adds an affirmative, incorrect owner prefix at view.go:1169; the selection fallback is unchanged.

📌 In this PR:

• Recent label branch — shows the unresolved historical owner.
• Favorites label branch — can show the same owner when the favorite came from a historical Recent entry.
• New rendering tests — construct owners directly and never check that the displayed owner matches the provider used on Enter.

🔒 Unchanged on main: Recent-history retention, provider-manager rename/removal, and the existing selection fallback. Their behavior does not need a redesign for this display fix.

🔧 Required correction: Make the mixed-group label identify the effective provider that the current selection path will use, including when a historical owner no longer resolves. Cover a removed or renamed profile through actual picker assembly and selection, including the Favorites route. Preserve the stale row and its current fallback behavior.

🛠️ Author fix: Close this identity mismatch for both in-diff groups in one pass; changing only the first cited conditional leaves the sibling group wrong. Keep the repair in the new labeling path and its direct supporting picker data/tests; do not rebuild config storage or provider switching.

🚫 Out of scope: Removing stale history, changing the existing stale-entry fallback, or redesigning provider identities.

---

🟡 P2 — Preserve the model name when adding a long owner prefix

📍 Where: internal/tui/view.go:1123,1169 and the changed width test.

💥 What fails: Saved profile names have no length limit. With a 70-column owner and a short model ID, the new prefix fills the picker’s maximum 76-column overlay. fillPaletteLine then truncates from the right, so two Recent rows for different models under that provider can both show only the owner and an ellipsis. Favorites have two fewer cells because of * . Before this PR, the short model names were visible on those same rows. Measuring the full new label does not prevent clipping once the overlay hits its cap; the new width test uses a prefix that fits below it.

🔎 Root cause: The new unbounded owner + " · " prefix is placed before the model, while the existing overlay has a fixed maximum width and truncates the composed row from the right.

📜 Stated contract:

“The model picker must title each row with the model NAME, not the models.dev marketing description.” — existing model_picker_display_test.go. Issue #840 also requires the owning provider to be visible before selection.

🏷️ Attribution: PR-worsened. At merge base and live main, the same short model appears without this prefix; at the PR head, the new prefix can erase it. The causal addition is view.go:1169; view.go:1123 measures it but cannot override the existing 76-column cap.

📌 In this PR:

• Recent row label — long owner can consume the model field.
• Favorites row label — the same prefix plus the favorite marker can consume it sooner.
• Width measurement and new width test — cover the full label only while it fits, not the capped case.

🔒 Unchanged on main: The 76-column overlay limit and generic right-truncation helper. Long model names could already truncate, but a short model disappearing because of the new prefix is this PR’s regression.

🔧 Required correction: Keep a short model identifier visible alongside an owner cue when an admitted profile name is long. Bound or lay out the newly added prefix so it cannot consume the entire short model field, and test both mixed groups at the 76-column cap. Full unbounded names cannot fit in a narrow terminal.

🛠️ Author fix: Apply the same bounded-label rule to both in-diff groups and make sizing/rendering use it consistently. Do not fix only the cited Recent example or only the width test; do not rewrite the shared truncation framework.

🚫 Out of scope: A general terminal-layout redesign or new global profile-name policy.

Merge readiness

The captured live main and merge base are both 99721c762f37cd43ac511007a5f51d1846df959e; the PR head is 7f939bba7124e9ae7dc634d765ff7b8b8c5fedce. GitHub reports the branch conflict-free (MERGEABLE), with all ten reported checks passing, but its merge state is BLOCKED. The earlier changes-requested review remains on the PR; confirm the applicable branch rule after these findings are addressed. No stale-base rebase or release-metadata drift is indicated.

The earlier stale-owner fallback and 76-cell long-owner cases are fixed on this head. Focused picker tests, make fmt-check, go vet ./internal/tui, go build ./..., and diff hygiene pass locally. A full local TUI package run has two failures that also reproduce in isolation in unchanged scroll/date tests; the CI unit, race, and Linux/macOS/Windows smoke checks pass.

Findings

🟡 P2 — Keep the provider distinguishable when long owner names share a prefix

📍 Where: internal/tui/view.go:1174-1175, fed by the new Recent and Favorites OwnerLabel assignments in internal/tui/picker.go:507,530.

💥 What fails: Save two profiles named work-subscription-provider-east and work-subscription-provider-west, and use GPT-5.6 from both. Recent retains two separately selectable provider/model rows, but both render as work-subscription-p… · GPT-5.6. Enter still uses their different full owners, so visually identical rows can switch to different accounts or billing paths. A Favorite has only one row per model ID, but its shortened owner is likewise ambiguous when another saved profile shares that prefix.

🔎 Root cause: The new owner cue always keeps the first 19 display cells plus an ellipsis. It never preserves the part that distinguishes admitted saved profile names. Deduplication and selection still use the full owner, so display identity can collapse while action identity remains distinct.

📜 Stated contract:

“Each row makes its owning provider visible before selection, so it is clear whether you are picking chatgpt · gpt-5.x or openai · gpt-5.x.” — approved issue #840, which also describes indistinguishable same-model rows as the failure.

🏷️ Attribution: Incomplete claimed fix. At the merge base and current live main, these two rows both showed only GPT-5.6; at this PR head they both show the same truncated owner plus GPT-5.6. The PR adds the owner cue to resolve #840, but the accepted ambiguity remains for valid shared-prefix profile names. A review-owned Go overlay reproduced the identical rendered labels from current assembly while confirming different Enter destinations.

📌 In this PR:

• Recent — two full-owner rows survive deduplication but collapse to one visible owner cue.
• Favorites — the single row's shortened cue cannot identify which of two prefix-sharing saved profiles it belongs to.
• Selection — correctly keeps the full owner; its distinction makes the display collision consequential.
• New tests — cover one long owner and short distinct owners, but no two long owners sharing a prefix.

🔒 Unchanged on main: Recent-history identity, full-owner selection, favorite one-row-per-model behavior, and provider-group headers. These do not require redesign.

🔧 Required correction: Keep the new mixed-group owner cue bounded and model text visible while making the effective destination distinguishable for colliding admitted profile names. Cover two same-model Recent rows with shared-prefix owners through rendering and Enter, plus a Favorite sourced from a colliding owner. The exact cue or layout can vary; the visible identity must match the provider selection will use.

🛠️ Author fix: Close this owner-identity rule for both in-diff mixed-group paths and their tests in one pass. Do not patch only the cited truncation example or change full-owner routing, config storage, or favorite identity semantics.

🚫 Out of scope: New profile-name limits, provider switching redesign, and unrelated picker search behavior.

🟡 P2 — Reserve model text at the terminal width actually available

📍 Where: internal/tui/view.go:1113-1135,1155-1178, with the new long-owner test in internal/tui/rendering_lime_test.go:1929-1949.

💥 What fails: The overlay permits a 30-cell terminal and passes a 26-cell row width to the renderer. With subscription-profile as owner, the fixed 20-cell prefix, separator, and row marker consume the row before GPT-5.6 begins. Recent renders subscription-profile · …; Favorites loses the model after its * marker as well. The same short model was visible at that width before this PR. The new test checks a 76-cell overlay only.

🔎 Root cause: The new owner prefix is budgeted against the overlay's maximum width, even when the actual terminal forces a smaller row. Measuring the composed label cannot prevent fillPaletteLine from clipping its rightmost model text.

📜 Stated contract:

“The model picker must title each row with the model NAME, not the models.dev marketing description.” — existing internal/tui/model_picker_display_test.go. Approved issue #840 also requires the owner cue before selection.

🏷️ Attribution: PR-worsened. At merge base and live main, the short model appears in the same 26-cell row. At this head, view.go:1174-1175 adds an owner prefix that erases it. A review-owned Go overlay reproduced the missing model for both mixed groups.

📌 In this PR:

• Recent and Favorites — both receive the fixed owner prefix and can lose the short model at a narrow terminal width.
• Overlay sizing and rendering — measure the same label, then cap the overlay to the actual terminal width and truncate the row from the right.
• New width tests — verify the maximum-width case but not a terminal narrower than the overlay minimum; selected and unselected markers occupy the same width.

🔒 Unchanged on main: The terminal-width cap and generic fillPaletteLine truncation. A short model fit through those paths before the new prefix.

🔧 Required correction: Size or lay out the new mixed-group owner cue against the actual rendered row width so a short model identifier remains visible with an owner cue on narrow terminals, including Favorites and selected rows. Add regression coverage at a width such as 30 cells as well as the existing wide case.

🛠️ Author fix: Close this width rule for both in-diff mixed groups and the new sizing/rendering tests in one pass. Do not fix only the cited Recent row or rewrite the shared truncation framework.

🚫 Out of scope: A general terminal-layout redesign, changes to provider-grouped rows, or a guarantee that arbitrarily long model names fit in every terminal.

[euxaristia]

Deriving the owner label from the same decision function Enter uses (modelPickerSwitchOwner) closes the stale-owner promise: Recent and Favorites can no longer advertise a provider the switch would not select. Pure display with tests.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Budget the model picker by rendered lines, not item count.

modelPickerOverlay still shows up to ten items, but renderModelPickerRow can emit two lines for a Recent or Favorites item. overlayViewportLines does not scroll the overlay. It discards lines beyond the transcript body height. A narrow terminal can therefore clip lower rows, the separator, or the footer. The selected row can also be outside the rendered portion.

Update modelPickerOverlay to calculate the visible window from rendered line counts, including group headers and fixed footer lines. Use the same row boundaries in selectModelPickerAtMouse; its current hit.y - rowStart mapping assumes one line per item.

Re-reviewed at 0e0e4f4f. @jatmn's stale-owner case is one I missed when I approved a45a8f91. It's closed now: the label comes from modelPickerSwitchOwner, the same decision Enter makes, and putting the stored owner back in the label fails TestModelPickerOwnerLabelMatchesSelectedProvider.

The two P2s and the CodeRabbit layout notes hold up as well. Besides that one, I ran eleven more mutations against the new code and ten fail a test: dropping the [N] prefix, keeping the start of a long owner instead of its end, never showing the full-name key, checking the key against the unfitted label, never moving the owner to its own line, budgeting the owner against the overlay cap instead of the row, ignoring the favorite marker, skipping the viewport fit, and hit-testing that assumes one line per row or skips group headers.

The one that survives is start = maxInt(start, m.picker.selected-count+1), and it matters. With ten two-line rows at a height of 20 or less, taking it out scrolls the selected row out of view. TestModelPickerFitsMultilineRowsToViewport runs at height 24, where the window never shrinks that far, so a shorter height in that loop would pin it. Not blocking.

internal/tui passes here on Windows apart from TestAltScreenTranscriptScrollKeepsFooterFixed, which depends on the directory the checkout sits in: main's code fails it in one directory and this head passes it in another. CI is 9/9 at head. Approving.
