the wrapper approach is correct and follows the existing pattern well. a few things to address:

1. pkg/progress/progress_test.go change is unrelated to copilot support. if it was an intentional fix, pls split it into a separate PR

2. the main loop forks 3-4 jq processes per JSONL line (validate, extract type, extract content, extract text). the codex wrapper does the entire translation in a single jq -c pipeline per line. not a blocker but worth optimizing - copilot can produce a lot of events

3. shell tests use macOS-only commands - stat -f '%m', date -v-1H, grep -P. these won't run on linux, which means they can't run in CI or docker. the other wrapper tests avoid platform-specific commands, would be good to follow the same pattern

4. minor - grep -oE 'docs/plans/[^ ]*\.md' for plan path extraction is fragile if the model formats the path differently. the find fallback helps but the grep could silently grab wrong text

thx for addressing the previous comments. most things look solid now, tests pass (59+25 shell, all Go tests, lint clean).

I haven't tried it with an actual copilot cli, so assuming you got it working end-to-end. the questions below are more theoretical than practical.

a few things after deeper review:

1. jq forks - down to 2/line from 3-4, which is better. the single-pipeline approach doesn't really work here because of per-line flow control decisions (plan boundaries, turn tracking), so I can live with this

2. plan boundary handling (lines 127-267) - none of the other wrappers (codex, gemini, opencode) implement plan signal parsing. I get why - copilot's autopilot mode runs multiple turns, so the wrapper needs to stop at boundaries. but does copilot cli have smth like --max-turns 1 or similar flag that would make this unnecessary? if the tool itself can limit to single-turn mode, ~90 lines of boundary extraction could go away

3. touch_existing_plan_for_ready (lines 242-267) - this is coupling between the shell wrapper and Go internals (FindRecent mtime behavior). if FindRecent changes its lookup strategy, this breaks silently. at minimum add a comment explaining why the touch is needed and which Go function depends on it

4. review adapter size - ~800 chars with a "FORMATTING RULE (strict)" section vs ~350 chars in codex adapter. is the markdown suppression rule actually needed for copilot, or is it defensive? if copilot consistently wraps output in markdown, then fine, but if not, trim it

thx, all prior comments addressed cleanly:

• progress_test.go reverted
• jq forks stable at 2/line
• macOS-only commands gone from tests
• plan path extraction replaced with content-compare (marker file + cmp -s), no more fragile grep
• touch_existing_plan_for_ready removed entirely - plan_written_since_start uses a script-internal marker instead of coupling to Go FindRecent
• plan-boundary comment at copilot-as-claude.sh:135-138 explains clearly why --max-turns wouldn't help (multiple signals in a single assistant.message, not across turns)
• review adapter size justified by the copilot markdown-default behavior, comment at :122-124 makes it discoverable

shell tests 83/83 + 29/29, go test clean, lint clean, shellcheck clean.

lgtm.
