+## Release PR Integration
+
+- Use scratch integration branches when triaging a crowded release queue. A
+  branch such as `scratch/v0.8.59-pr-train-YYYYMMDD` may merge or cherry-pick
+  many PR heads to expose conflicts, missing tests, duplicate work, and hidden
+  coupling quickly.
+- Treat scratch branches as evidence, not as the artifact to ship. Do not tag,
+  release, or fast-forward a release branch from a scratch train. Harvest the
+  safe resolved hunks or commits back into the release branch in narrow,
+  reviewable commits.
+- Prefer direct GitHub merge only when the PR is clean against the real landing
+  branch, has acceptable checks, and does not cross trust-boundary surfaces. A
+  PR that is clean against `main` can still conflict with a release branch; test
+  against the actual release head before calling it merge-ready.
+- For already approved PRs, start with a scratch merge against the release
+  branch, then decide between direct merge, cherry-pick with conflict
+  resolution, or credited harvest. Maintainer approval is a priority signal,
+  not permission to skip review or tests.
+- When harvesting, preserve or add machine-readable credit: keep the original
+  author where possible, add `Co-authored-by` using `.github/AUTHOR_MAP` or
+  GitHub numeric noreply identity, and include `Harvested from PR #N by
+  @handle` in the commit body so the auto-close workflow can close the PR with
+  credit after it reaches `main`.
+- Close or update issues and PRs only after verifying the landed commit on the
+  relevant branch. If the release branch already contains equivalent behavior,
+  leave a clear note linking the commit and describing any remaining delta.
+- For the current v0.8.59 queue, use `docs/V0_8_59_RELEASE_TRIAGE.md` as the
+  starting triage packet, then refresh GitHub state before acting.

+# Claude Repository Guidance
+
+Read `AGENTS.md` first. This file exists as a compatibility instruction source
+for Claude-based agents working in this repository.
+
+## Stewardship Defaults
+
+- Treat community PRs and issues as maintainer evidence. Inspect code, tests,
+  linked issues, comments, and CI before merging, harvesting, closing, or
+  deferring work.
+- Do not tag, publish, create a GitHub Release, or push release artifacts
+  without Hunter's explicit approval.
+- Keep CodeWhale branding while preserving first-class DeepSeek model/provider
+  support and legacy migration care.
+- Preserve contributor credit for harvested work with authorship,
+  `Co-authored-by`, `Harvested from PR #N by @handle`, and changelog/release
+  notes where applicable.
+
+## Scratch Integration Branches
+
+- For release queues, create disposable local branches from the real landing
+  branch, for example `scratch/v0.8.59-pr-train-YYYYMMDD`.
+- Use the scratch branch to merge or cherry-pick candidate PR heads in batches
+  and learn which conflicts, tests, and overlaps are real.
+- Do not ship the scratch branch itself. It may contain noisy merge commits,
+  partial conflict resolutions, and unrelated PR interactions.
+- After the scratch experiment, move only the safe result back to the release
+  branch as narrow commits or direct merges. Keep each final commit explainable
+  and testable.
+- A PR that is clean against `main` is not necessarily clean against a release
+  branch. Test mergeability against the branch that will actually receive the
+  work.
+- For already approved PRs, treat approval as a strong priority signal. Still
+  inspect diffs, comments, check results, and release-branch conflicts before
+  landing.
+
+## v0.8.59 Release Work
+
+- Base release triage on `codex/v0.8.59-release-ready` unless Hunter gives a
+  newer branch.
+- Work the queue in this order: release blockers, recently approved PRs, clean
+  PRs with small scope, blocked PRs with obvious fixes, dirty PRs that can be
+  harvested safely, then larger architecture issues.
+- Prefer batching PR conflict discovery on scratch branches, then harvesting
+  reviewed, credited, tested slices back into the release branch.
+- Before claiming an issue is done, verify whether the release branch already
+  contains equivalent work. If it does, prepare the GitHub note/closure path
+  instead of reimplementing it.
+- For the current v0.8.59 queue, start with
+  `docs/V0_8_59_RELEASE_TRIAGE.md`, then refresh live GitHub state before
+  taking action.

+# v0.8.59 Release Triage
+
+Generated on 2026-06-12 for `Hmbown/CodeWhale`.
+
+Current local release branch at handoff time:
+
+- Branch: `codex/v0.8.59-release-ready`
+- Head: `ca826bb2 fix(tui): clarify Codex response errors`
+- Remote: `origin=https://github.com/Hmbown/CodeWhale.git`
+
+## Mission
+
+Move v0.8.59 toward release by actively landing, harvesting, or closing the
+remaining PR and issue queue. Do not only summarize. Use GitHub and local Git
+state to decide which items are already landed, which can be directly merged,
+which need a credited harvest, and which should be deferred with a clear note.
+
+Start from `codex/v0.8.59-release-ready` unless Hunter gives a newer branch.
+
+## Key Operating Idea: Scratch Integration Branches
+
+Hunter's "dummy branch" idea is feasible and useful. Use it.
+
+The scratch branch is for discovery and acceleration:
+
+- create it from the real release branch;
+- merge or cherry-pick many candidate PR heads into it;
+- use conflicts, tests, and diff review to learn what composes;
+- harvest only the safe result back into the release branch.
+
+The scratch branch is not the thing to ship. It can contain noisy merge commits,
+temporary conflict resolutions, and interactions between unrelated PRs.
+
+Suggested local workflow:
+
+```bash
+git fetch --prune origin
+git switch codex/v0.8.59-release-ready
+git pull --ff-only
+git switch -c scratch/v0.8.59-pr-train-$(date +%Y%m%d-%H%M)
+```
+
+Fetch specific PR heads into temporary refs:
+
+```bash
+git fetch origin pull/3152/head:refs/tmp/pr-3152
+git fetch origin pull/3148/head:refs/tmp/pr-3148
+git fetch origin pull/3150/head:refs/tmp/pr-3150
+```
+
+Dry-run conflicts before touching the scratch branch:
+
+```bash
+base=$(git merge-base origin/codex/v0.8.59-release-ready refs/tmp/pr-3152)
+git merge-tree "$base" origin/codex/v0.8.59-release-ready refs/tmp/pr-3152
+```
+
+On the scratch branch, merge one candidate at a time:
+
+```bash
+git merge --no-ff refs/tmp/pr-3152
+```
+
+If it conflicts, resolve only enough to learn whether the PR should be directly
+merged, cherry-picked, harvested, or closed as already landed. After the scratch
+experiment, return to the release branch and apply the final result as narrow
+commits.
+
+Use direct GitHub merge only when the PR is clean against the actual landing
+branch. Many PRs are clean against `main` but conflict against
+`codex/v0.8.59-release-ready`.
+
+If a scratch branch needs CI, push it only as a clearly named scratch branch or
+draft PR after Hunter authorizes that branch/CI lane. Never tag or publish from
+scratch.
+
+## Credit Contract
+
+When harvesting contributor work:
+
+- Preserve the original author when practical.
+- Add `Co-authored-by` using `.github/AUTHOR_MAP` or:
+
+```bash
+gh api users/<login> --jq '"\(.id)+\(.login)@users.noreply.github.com"'
+```
+
+- Include this line in the commit body:
+
+```text
+Harvested from PR #N by @handle
+```
+
+The repo has `.github/workflows/auto-close-harvested.yml`, which closes PRs
+after such commits land on `main`. Until then, leave clear comments linking the
+release-branch commit or harvest plan.
+
+## Recently Approved PRs Already Covered
+
+`Hmbown` submitted formal `APPROVED` reviews on these PRs on 2026-06-12. A
+follow-up scratch-merge pass against `codex/v0.8.59-release-ready` found that
+the release branch already contains equivalent or stronger implementations. Do
+not spend another cycle re-harvesting them; close them after the release branch
+lands on `main`, or leave/update triage comments if they remain open.
+
+### PR #3152 - SSE `data:` parsing
+
+- URL: https://github.com/Hmbown/CodeWhale/pull/3152
+- Author: `wgeeker`
+- Title: `fix(SSE): accept SSE data lines without space after colon`
+- Hunter approval: 2026-06-12T16:10:34Z
+- GitHub merge state against `main`: `BLOCKED`
+- Non-success checks shown by `gh`: none
+- Head: `fix/sse-data-prefix-no-space`
+- Commit: `50445eb3 fix: accept SSE data lines without space after colon`
+- Files: `crates/tui/src/client.rs`, `client/anthropic.rs`, `client/chat.rs`,
+  `client/responses.rs`
+- Release-branch result: scratch merge produced a literal zero diff.
+- Covered by release commit: `2f717d33 fix(tui): accept compact SSE data
+  fields`.
+- Notes: release branch already has an identical `extract_sse_data_value`
+  helper and equivalent tests.
+- Action: no harvest needed. Keep the triage comment as credit and close after
+  the release branch lands on `main`.
+
+### PR #3148 - `--model auto` / `DEEPSEEK_MODEL`
+
+- URL: https://github.com/Hmbown/CodeWhale/pull/3148
+- Author: `hongchen1993`
+- Title: `fix(exec): resolve --model auto via DEEPSEEK_MODEL env and reorder ExecArgs`
+- Hunter approval: 2026-06-12T16:10:21Z
+- GitHub merge state against `main`: `CLEAN`
+- Non-success checks shown by `gh`: none
+- Head: `fix/auto-model-agent-plan`
+- Commits: `b67f4add`, `55e66a6e`
+- File: `crates/tui/src/main.rs`
+- Release-branch result: fully covered.
+- Covered by release commit: `862cb2e3 fix(exec): preserve auto model handoff`.
+- Notes: `ExecArgs` is already reordered so the prompt is last, and the release
+  branch env fallback is a superset: `CODEWHALE_MODEL`, then `DEEPSEEK_MODEL`.
+- Action: no harvest needed. Keep the triage comment as credit and close after
+  the release branch lands on `main`.
+
+### PR #3150 - prompt source map / context usage
+
+- URL: https://github.com/Hmbown/CodeWhale/pull/3150
+- Author: `idling11`
+- Title: `feat(context): add prompt source map and context-usage report (#3143)`
+- Hunter approval: 2026-06-12T16:10:10Z
+- GitHub merge state against `main`: `CLEAN`
+- Non-success checks shown by `gh`: none
+- Head: `feat/3143-prompt-source-map`
+- Commits: `e91d4984`, `97e711c4`, `c463dac4`, `b8efcde0`
+- Files include `crates/tui/src/context_report.rs`, command wiring,
+  `compaction.rs`, `localization.rs`, `main.rs`, and TUI UI/app files.
+- Closing issue: #3143
+- Release-branch result: independently implemented.
+- Covered by release commit: `0986cabb feat(tui): add context source map
+  report`.
+- Notes: release branch already has `/context [report|json|summary]` and
+  `codewhale doctor --context-json`. Gemini's string-slicing and duplicate
+  `AGENTS.md` findings apply to the PR implementation, not the release branch:
+  the release module does no string slicing and no `AGENTS.md` processing. The
+  PR's remaining tests target its divergent API and do not transplant cleanly.
+- Action: no harvest needed. Keep the triage comment as credit and close after
+  the release branch lands on `main`.
+
+## Current v0.8.59 PR Queue
+
+Open PRs carrying `v0.8.59` at the handoff scan, updated with the
+release-branch scratch triage pass.
+
+### Merge cleanly into the release branch (await Hunter approval)
+
+- #3062 - fix(tools): apply strict mode per schema
+- #3008 - docs(prompt): clarify Constitution trust framing
+- #3006 - fix update release-download timeout/error messaging
+- #3003 - bump `clap_complete` (CodeQL neutral)
+- #3002 - bump `rustls` (CodeQL neutral)
+- #3001 - bump `reqwest` (CodeQL neutral)
+- #2971 - expose matched approval rule metadata
+- #2943 - normalize macOS Cmd/SUPER to CONTROL
+
+These can be landed directly or via a small scratch train, but they did not have
+Hunter approval at the 2026-06-12 re-scan (reviewDecision empty on all). Ask for
+approval or review each one before merging. Lowest-risk first: docs PR #3008,
+update-network fallback #3006, then the three dependency bumps
+#3001/#3002/#3003.
+
+### Already landed on the release branch (verified by scratch merge, zero residual diff)
+
+Triage comments with the covering commits were posted on each on 2026-06-12.
+Close after the release branch reaches `main`.
+
+- #2901 - localize ToolFamily labels. Zero unique commits vs release branch.
+- #3056 - hotbar number keys. Covered by `3de1d35c` with stronger tests
+  (extra `needs_redraw` assertions).
+- #3052 - verbosity settings. Covered by `42de833d`, which is a superset
+  (case/whitespace-tolerant `is_concise_verbosity`).
+- #3011 - provider source tracking + unsupported-TUI errors. Release branch
+  already has `ProviderSource::Cli/Env` and `provider_is_supported_by_tui`
+  with per-source error messages.
+- #3009 - cli-compare Harbor harness. Release-branch script is a strict
+  evolution (adds `_first_present`/`_stable_path` helpers).
+- #2895 - `siliconflow_cn` provider config field. Test merge produced zero
+  residual diff.
+
+### Genuinely missing work; needs review/rebase (commented 2026-06-12)
+
+- #3051 - feat(voice): `/voice` speech-to-text. Release branch has NO voice
+  command — this is a real 711-line feature. Conflicts in `commands/mod.rs`,
+  `localization.rs`, `tui/ui.rs`, and it smuggles an unrelated
+  `switch_provider` change (`app.api_key`/`app.base_url` reassignment) that
+  collides with the release branch's `reasoning_effort.normalize_for_provider`
+  line. Asked contributor to split/rebase; Hunter decides 0.8.59 vs next.
+- #3005 - refactor(config): provider metadata registry. NOT landed — real
+  ~300-line net simplification delta. One semantic conflict: release branch
+  registers config key `siliconflow_cn`; PR uses `siliconflow` + aliases.
+  Recommend deferring the refactor to the cycle after v0.8.59 unless Hunter
+  wants it in; asked for rebase onto the release branch.
+
+### Blocked against `main` or with failing checks
+
+- #3053 - docs: add Upgrading from deepseek-tui section. Merge state: BLOCKED.
+- #3013 - detect legacy deepseek/deepseek-tui binary and print migration
+  instructions. Merge state: BLOCKED; macOS test failed and Windows test was
+  cancelled at scan time.
+- #2995 - bump actions/stale from 9 to 10. Merge state: BLOCKED; version drift
+  failed and CodeQL was neutral.
+- #2903 - build static linux x64 binaries with musl. Merge state: BLOCKED.
+
+### Dirty / needs rebase, conflict triage, or harvest
+
+- #3010 - exclude Calm personality overlay from default prompt path
+- #2940 - localize Cmd command output messages
+- #2932 - localize mode-picker messages
+- #2929 - localize pending-input preview messages
+- #2926 - localize onboard-welcome and app-mode-switch messages
+- #2921 - localize sidebar panel labels, status messages, and focus indicators
+- #2919 - localize ConfigEdit labels and default values
+- #2918 - localize ConfigSection and ConfigScope labels
+- #2899 - localize SubAgents surface
+- #2894 - localize composer surface
+- #2879 - align Hugging Face provider docs, errors, and tests
+- #2851 - refactor TUI command groups into focused implementations; draft
+- #2808 - runtime-api session save, undo/retry, and snapshot endpoints; dirty,
+  `needs-human`, lint failing
+- #2773 - complete provider fallback chain
+- #2239 - i18n Phase 1-4b wiring plus rebase compile fixes
+
+## Milestone Issues
+
+At scan time, milestone `v0.8.59` had 76 open issues and 35 open PRs, for 111
+open milestone items. Issue priorities:
+
+1. #3063 release tracker and release-blocker coordination.
+2. Close/update already-covered approved PRs #3152, #3148, #3150 after the
+   release branch reaches `main`; do not re-harvest them.
+3. User-visible bugs/regressions: #3064, #3067, #3065, #3080, #3088, #3095,
+   #3094, #3070, #1812, #1679, #1190, #1120, #1060, #861, #759, #1920.
+4. Provider/model catalog and cost/context: #3086, #3085, #3084, #3083, #3076,
+   #3075, #3073, #3072, #3071, #3066, #2574, #1310, #868.
+5. Tool and runtime UX: #3146, #3145, #3144, #3143, #3102, #3079, #2886,
+   #1917, #1847, #1822, #1802, #1794, #1186.
+6. TUI and command polish: #3081, #3077, #3074, #3069, #2870, #2791, #1871,
+   #1722, #963.
+7. Docs/localization/migration: #3093, #3092, #3091, #3090, #3087, #3068,
+   #3061, #3058, #1447, #1118, #683.
+
+For each issue, first ask: "Is this already satisfied on
+`codex/v0.8.59-release-ready`?" If yes, prepare a closure/update note with the
+commit hash. If no, implement or harvest the smallest safe slice.
+
+## Suggested Next Work Session
+
+Conflict triage of #3056/#3052/#3051/#3011/#3009/#3005 was completed on
+2026-06-12 (scratch branch `scratch/v0.8.59-conflict-triage-20260612`,
+local only). Remaining:
+
+1. Get Hunter's explicit approval to land the eight release-branch-clean PRs:
+   #3062, #3008, #3006, #3003, #3002, #3001, #2971, #2943.
+2. Land those in small batches, starting with docs/dependencies/low-risk fixes,
+   and run focused checks after each batch.
+3. Hunter decisions needed: include #3051 (voice) in v0.8.59 or defer; defer
+   #3005 (provider registry refactor) or reconcile the `siliconflow_cn` vs
+   `siliconflow`+aliases key naming and land.
+4. After the release branch reaches `main`, close the verified-covered PRs:
+   #3152, #3148, #3150, #2901, #3056, #3052, #3011, #3009, #2895.
+5. Triage the blocked PRs (#3053, #3013, #2995, #2903) and the dirty/localize
+   train, then move to milestone issues per the priority list above.
+6. Update `CHANGELOG.md` and close/update linked issues only after verification.
+
+## Useful Commands
+
+List PRs with v0.8.59:
+
+```bash
+gh pr list -R Hmbown/CodeWhale --state open --limit 200 \
+  --search 'milestone:v0.8.59' \
+  --json number,title,url,headRefName,baseRefName,mergeStateStatus,reviewDecision,isDraft,statusCheckRollup
+```
+
+Find formal reviews by Hunter on open PRs:
+
+```bash
+for n in $(gh pr list -R Hmbown/CodeWhale --state open --limit 200 --json number --jq '.[].number'); do
+  gh pr view -R Hmbown/CodeWhale "$n" --json number,title,url,reviews,updatedAt \
+    --jq '. as $pr | [.reviews[]? | select(.author.login == "Hmbown") | {number:$pr.number,title:$pr.title,url:$pr.url,prUpdatedAt:$pr.updatedAt,state:.state,submittedAt:.submittedAt}][] | [.number,.state,.submittedAt,.prUpdatedAt,.title,.url] | @tsv'
+done
+```
+
+Check whether a PR has patch-equivalent commits already on the release branch:
+
+```bash
+git log --cherry-mark --right-only --oneline \
+  origin/codex/v0.8.59-release-ready...refs/tmp/pr-3152
+```
+
+Show conflicts without modifying the worktree:
+
+```bash
+base=$(git merge-base origin/codex/v0.8.59-release-ready refs/tmp/pr-3152)
+git merge-tree "$base" origin/codex/v0.8.59-release-ready refs/tmp/pr-3152
+```
