-- 2025-08-20:omsendertrack: stop towards full completion of module.
+- 2025-08-25: tcpsrv: refactor IO loop; rearm-before-unlock; poll path
+  Improve maintainability and robustness of the TCP server by clarifying
+  locking/ownership, tightening invariants, and simplifying queueing.
+  Also fix a long-standing pragma macro typo across the tree.
+  Impact: Internal behavior only. EPOLL re-arm now occurs while holding
+  pSess->mut; starvation cap counts only successful reads.
+  Before/After:
+  Before: EPOLL re-arm happened after leaving the critical section; read
+  starvation cap counted loop iterations; closeSess() sometimes unlocked;
+  select_* helpers used on non-epoll path; enqueueWork() returned status.
+  After: EPOLLONESHOT is re-armed before unlocking; starvation cap counts
+  only RS_RET_OK reads; closeSess() never unlocks; poll_* helpers replace
+  select_*; enqueueWork() is void (best-effort).
+  Technical details:
+  - Replace notifyReArm() with rearmIoEvent() (EPOLL_CTL_MOD with
+    EPOLLONESHOT|EPOLLET; asserts efd/sock; logs on failure).
+  - doReceive(): explicit state machine; would-block path re-arms before
+    unlock; close path unlocks then calls closeSess(); starvation handoff
+    enqueues without re-arming.
+  - Initialize ioDirection for listener and session descriptors; add
+    assert(sock >= 0) and widespread ATTR_NONNULL annotations.
+  - startWrkrPool(): single finalize rollback (cancel/join partial
+    threads; destroy cond/mutex); stopWrkrPool(): destroy cond/mutex.
+  - enqueueWork(): FIFO append under lock and cond signal; returns void.
+  - Cleanup hardening on construct failure: free ppLstn, ppLstnPort,
+    ppioDescrPtr; free fromHostIP on SessAccept() error.
+  - Non-epoll: rename select_Add/Poll/IsReady -> poll_*; RunPoll() uses
+    poll_* and sets sane ioDirection defaults.
+  - Typo fix: standardize PRAGMA_IGNORE_Wswitch_enum in header and all
+    users (action.c, rainerscript.c, template.c, tcpsrv.c).
+- 2025-08-25: omsendertrack: stop towards full completion of module.
   Work towards full completion of the module’s interface as it exits PoC.
   The new name senderid (formerly: template) matches intent (identify a
   sender, not an output format) and avoids confusion.  Also make state
