7dc657b1bd feat(ha-repl-hardening): populate stateReport in standby heartbeat reply (task 2.3)
OPCode_nop handler now sends stateReport {applied_lsn, config_tag}
instead of nodata. Function in ha.c for unit-test linkability.
Two tests: warm state and zero-state fresh standby (Req 1.4).

6bbcff62ca feat(ha-repl-hardening): add batch WAL catch-up on standby side (task 2.2)
Extend ha_apply_wal_catchup_entry with batch branch:
- Check n_entries > 0, iterate entries[] list in order
- Apply each via apply_wal_entry(); skip NULL/errors without crash
- Advance applied_lsn once after full batch (not per-entry)
- n_entries == 0 falls through to task 2.1 single-entry path
4 new unit tests covering full batch, partial batch, error skip, fallback

647b88ce57 feat(ha-repl-hardening): wire OPCode_walCatchupEntry standby handler (task 2.1)
Replace stub with ha_apply_wal_catchup_entry() calling apply_wal_entry().
CAS-advance applied_lsn on success; log ERROR and skip on failure.
Standby stays in CTRL_STANDBY throughout. 3 new unit tests.

e31673dd88 chore: checkpoint all prior work for clean state
Captures all uncommitted work from ha-config-bootstrap,
ha-heartbeat-liveness, and associated spec/tooling updates:

- src: ha.c, ha.h, cluster.c, config_repl.c, myapp.c, raft.c —
  heartbeat liveness, RDHUP integration, committing phase fixes
- tests: test_ha_role.c, test_config_repl.c, test_ha_rdhup_integration.c,
  test_p1_integration.c, test_p3_hardening.c, scheduler test
- specs: election-iomgr-refactor, ha-heartbeat-liveness,
  ha-peer-connection-reuse, raft-library (new); ha-config-bootstrap
  and election-iomgr-refactor task/research updates
- tooling: .wolf/ state, ha/data cluster fixtures, raft/raft.tla,
  src/build symlink, xce-build skill update

26393e919c feat(config-repl): add raw capnp shims for OP_replConfig wire protocol
xce_replconfig_reply_raw() - primary sends reply with real bytes via endpoint
xce_replconfig_req_ssl() - standby sends request over raw SSL socket
xce_replconfig_reply_ssl_decode() - standby decodes reply from raw SSL
xce_upgrade_config_req_extract() - documents architectural limitation; returns -ENOTSUP
xce_upgrade_config_req_extract_raw() - extract bytes from raw packet for OP_upgradeConfig

Same bypass pattern as existing xce_replconfigpush_req_raw(): build the
capnp message directly via capn_new_list8 + capn_setv8, sidestepping the
encode_Data_ptr path that routes raw bytes through xce_data_t (a
discriminated cluster-data union that cannot carry raw byte arrays).

Unblocks handle_config_request() and do_one_config_fetch() wiring.

Task A research finding: xce_upgrade_config_req_extract(xce_request_t*)
is unimplementable because xce_decode() calls capn_free() before any
handler runs, and decode_Data_ptr converts the wire-format List(UInt8)
into a zero-filled xce_data_t. Task D must capture the raw io_packet_t
bytes before xce_decode tears them down, then call the _raw variant.

f3babec5bc feat(config-repl): implement wait_all_with_timeout() for push fan-out
Replaces blocking pthread_join() per thread with a CLOCK_MONOTONIC
deadline + 5ms poll loop. CONF_PUSH_TIMEOUT_MS (500ms) now enforced.
Matches design §6.3 aggregate timeout guarantee.

- Add done field to push_ctx_t; push_thread sets it on exit
- Add static wait_all_with_timeout() before push_config_to_standbys()
- Wire push_config_to_standbys() to use wait_all_with_timeout()
- Add #include <stdatomic.h> to config_repl.c
- Guard push_ctx_t local typedef with #ifndef XCE_TESTING
- Expose push_ctx_t and wait_all_with_timeout_for_test() in header
  under XCE_TESTING for unit test access
- Add test_wait_all_with_timeout_slow_threads (timeout fires, acked=0)
- Add test_wait_all_with_timeout_fast_threads (all complete, acked=3)
- Update design doc §6.3 with actual implementation signature and
  5ms poll interval note

2ed7e34e25 fix(config-repl): conf_save_config() must use workdir/name not workdir
load_primary_config() reads from workdir/name/conf — conf_save_config()
was writing to workdir/conf. Latent bug: would have corrupted upgrade
restart cycle once Task 11 wired the upgrade path.

Update all conf_read_current_filename, conf_get_saved_tag, and
conf_check_stale calls in the test suite to use the corrected
effective_dir (workdir/name) path structure. Add new test
test_conf_save_config_path_consistency that explicitly verifies the
written path matches what load_primary_config() reads.

cd02cf40d2 feat: add load_primary_config(), myconf_fini(); remove static cf global from myconf.c
- load_primary_config(): resolves conf/current, reads raw bytes, computes
  SHA-256 tag, decodes Cap'n Proto via load_cluster_config_from_file(),
  checks reserved names, sets config_generation, checks staleness
- myconf_fini(): frees conffile and cluster_config (calls free_ClusterConfig)
- Remove static cf global from myconf.c; get_default_conf() now uses a
  local struct cluster_configuration* via load_cluster_config()
- Add load_primary_config_for_test() under XCE_TESTING in config_repl.c
  to test path resolution without triggering FATAL
- Add xce/cluster_def.h include to config_repl.c and test_config_repl.c
  so cluster_t is complete when XCE_TESTING is active
- TDD: test_load_primary_config_missing_returns_error passes (18/18)

491c2550c2 feat: add config_repl Phase 1 — HEAD-file storage, SHA-256, trim, stale check, sanitise_cn
- config_repl.h/.c: atomic versioned file save, pointer file, trim, stale check
- test_config_repl.c: 17 Unity tests covering all Phase 1 storage functions
- typemap.h: add repl/heartbeat types + union members for xce_request_t/xce_reply_t
- clusterconfig.h: add config_generation field to cluster_config_t (capnp schema ref)
- meson.build: add config_repl.c and test_config_repl.c to build targets
- controller_test.c: register test_config_repl dispatch function
