Mergemaster needs more headroom for heavy merges (e.g. the slug-to-numeric
ID migration touching many files, or the FS-shadow deletion stories that
require fixing test setup across the codebase). 60 turns wasn't enough
for the larger ones.

- Append to all coder/opus system_prompts: for delete/signature-change
refactors, delete first and let compiler errors guide the call-site
walk; do not pre-read files predicting breakage. Reduces exploration
overhead on mechanical refactors.
- Bump mergemaster inactivity_timeout_secs 300 -> 900 (15 min) so
mergemaster survives the 5-minute API rate-limit backoff. Without
this, mergemaster gets killed for inactivity while waiting on rate
limit clear, blocking all merges.

Stories like the broadcaster-consumer migrations legitimately need ~60
substantive turns (16 ProjectConfig initializer sites + main.rs subscriber
+ reading existing patterns to mirror). 50 was too tight.

Real cause of mergemaster turn-burnout: not merge conflicts, just polling
overhead. The server-side tool_merge_agent_work IS designed to block until
the merge completes, but the MCP client times out after 60s. The agent
then polls get_merge_status, with 30-60s sleeps between polls — each
poll cycle costs 2 turns (sleep + tool call). The merge takes 5-10 min
for a clean run, so the agent burns 10-20 turns just waiting.
Updated workflow tells mergemaster:
- 'operation timed out' is normal, do NOT immediately re-call (would queue
a duplicate merge)
- Use Bash sleep 300 (one 5-min wait = 1 turn) between polls
- Cap at 3 polls = 15 minutes total, plenty for any clean merge
- Reserve turns for actual fix-up work if gates fail
Combined with the earlier 30→60 turn / $5→$15 budget bump, this should
land any merge with no real conflicts in 3-5 turns total. Plenty of
headroom remaining for genuine gate-fix work.
30 turns is too tight for non-trivial merge gate failures. Combined with
the 3-retry cap, stories with any post-merge fix-up needed (cargo fmt
nits, slightly out-of-date diffs after parallel merges, etc.) get
permanently blocked.
This is a stopgap until story 668 lands (which will keep gates_passed=false
work in the coder stage entirely, so mergemaster only ever sees clean
diffs and the original 30 turns / $5 is fine again).
Agents now read specs/00_CONTEXT.md (what the project does) and
specs/tech/STACK.md (tech stack + source map) in addition to the
README. STACK.md rewritten to reflect current state — removes stale
references to biome, tauri-specta, .story_kit.

Agents now know to add //! module comments and /// doc comments
to new public items, keeping documentation consistent with the
codebase-wide doc pass from story 542.

run_tests MCP tool now spawns tests in the background and returns
immediately. Agents poll get_test_result to check completion. This
prevents zombie cargo processes from holding the build lock when the
CLI times out the MCP call before tests finish.
Also fixes agent permission mode: acceptEdits replaces invalid
allowFullAutoEdit that was causing agents to crash-loop on spawn.

Agents were spending entire $5 budgets grepping the codebase and reading
git history instead of making fixes when the story already specifies
exact file paths and function names. Changed bug workflow from
"investigate root cause first" to "trust the story, act fast" — go
directly to the specified location when the story tells you where.

Agents were running script/test directly through the PTY, streaming
the full output of npm install, cargo clippy, cargo test, and frontend
builds into session logs. This tripled session log sizes (~200KB to
~600KB per session) and contributed to CLI SIGABRT crashes.
The run_tests MCP tool already runs script/test server-side and returns
a truncated JSON summary. Agents now use it exclusively.
