Original description by @fixfon With the Compact chip enabled on a resumed Claude thread, sending `/compact` with instructions queued a bare compaction before the instructed command. This could compact twice and lose the benefit of the supplied instructions. Recognize `/compact` followed by whitespace as an explicit compaction request, so it bypasses automatic pre-send compaction. Ordinary messages retain their existing behavior. Validation: 138 focused cases passed, including one retained regression case that fails with the original exact-match predicate. Web typecheck and format passed; scoped lint reported existing warnings. Independent Claude Opus and GPT-6.1 reviews approved the source. Integrated proof used the actual web composer, orchestration, Claude SDK, and an offline stream-json CLI peer. A completed peer turn was created first, then its context usage was aged to enable the Compact chip. Each case started from the same stopped snapshot and the SDK launched with `--resume`. The peer reports synthetic compaction: this verifies transport and command sequencing, not real model summarization or authentic Claude transcript restoration. Web was exercised; no native Electron or mobile run is claimed. | Case | Commands received by the peer | | --- | --- | | Baseline, instructed compact | `/compact`, then `/compact keep the auth refactor notes` | | Reviewed head, instructed compact | `/compact keep the auth refactor notes` only | | Reviewed head, ordinary message | `/compact`, then `Continue reviewing the auth refactor notes.` | Baseline precondition: Compact chip enabled with instructed command entered. ![Baseline precondition: Compact chip enabled with instructed command entered](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/441e01ebb6e3e6d4/browser-screenshot-localhost-mvejvk8j-ba2b8203.png) Reviewed head: one instructed compact command completed. ![Reviewed head: one instructed compact command completed](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/8c6b034ac395b25d/browser-screenshot-localhost-mvejyig4-e0c6426d.png) Ordinary-message control: automatic compact then queued normal message. ![Ordinary-message control: automatic compact then queued normal message](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/794088b10f4c2136/browser-screenshot-localhost-mvejzafz-6d58e461.png) Sanitized command traces: [baseline](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/05c26314f9f21da9/20236-baseline-commands.json), [reviewed head](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/143e876aadb42703/20236-head-commands.json), [ordinary-message control](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/dcc5505f4acca9d8/20236-control-commands.json).

Maintainer takeover: Claude Opus 5.5 for tests/review, Claude Fable 5.1 for implementation, GPT-6.1 for independent review; Claude Code and Codex harnesses.
## Takeover Retains @fixfon’s commits from [#20236](https://github.com/pingdotgg/t3code/pull/20236). Main moved submission into `planComposerTurn`; the same command-boundary guard is ported there. The existing dispatch regression test is expanded, and the single-caller helper is removed. ## Evidence Final head [f2177590](https://github.com/pingdotgg/t3code/commit/f21775904c4e1c647a0b4279f752013208694bb2), merged main [4812dcad](https://github.com/pingdotgg/t3code/commit/4812dcad02a86874533540e6a0c4b7f5eaea297a). **Proof incomplete:** all24 interaction recordings exist, but six wide settled-image comparisons require correction of an unrelated source-control card difference.

Historical records remain unchanged; the old mismatched wide diffs remain rejected and are replaced by the matched pairs below.

No unverified rows remain within the synthetic responsive-web sequencing scope. The auditor played all 24 recordings completely and checked their narrated steps against sanitized command/resume traces. Historical wide recordings prove sequencing only and retain their disclosed card mismatch; replacement stills establish matched visual parity. C5 stills show Never opt-out; reused recordings show restoration to When you return and the subsequent automatic-predecessor send. The six new wide pairs run the entire base [4812dca](https://git.cafe/pingdotgg/t3code/commit/4812dcad02a86874533540e6a0c4b7f5eaea297a) (merge-base of final head) versus the entire exact head [f217759](https://git.cafe/pingdotgg/t3code/commit/f21775904c4e1c647a0b4279f752013208694bb2). Reused 390px cells and recordings retain the disclosed changed-file baseline substitution method; they are not full-base runtime evidence.

All new sides settle exactly; old 390px cells are unchanged. Independent A1 wide-light head frames 1143ms apart have zero temporal differing pixels; rebuild versus delivered has 0 pixels >0, 0 pixels >16, maximum channel 0. No masks or pixel-difference waivers. A1 removes the duplicate bare command/boundary, moves the instructed row up and changes the minimap only to reflect the shorter timeline. The other four new wide control pairs have zero differing pixels at threshold zero. No unrelated visual differences were found. ![Before: bare compaction followed by instructed compaction](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/37c0055c2f5f5902/A1-1440-light-before-1.png) ![After: instructed compaction without the preceding bare compaction](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/694b31d6bfdf78e6/A1-1440-light-after-1.png) Scope: offline synthetic peer proves actual web composer/server/Claude SDK command sequencing and resumed transport.
