10 daysRename the library to wsap_vtcoreBerke Güzel
ncurses installs <term.h> and defines struct term. In a file that includes both headers, an ncurses TERMINAL * and this library's terminal are silently the same type. The name wsap_vtcore avoids the clash. The public header is now <wsap_vtcore/wsap_vtcore.h>. Every global symbol uses the wsap_vtcore_ prefix, every macro uses WSAP_VTCORE_, and the shared library is libwsap_vtcore.so.0. The default terminal name is now "wsap_vtcore". The ISA override variable is WSAP_VTCORE_ISA. No other behavior changes. The amalgamation writes wsap_vtcore.c and wsap_vtcore.h. Co-Authored-By: Claude Haiku 5.5 <noreply@anthropic.com>
10 daysReject a scrollback above TERM_SCROLLBACK_MAXBerke Güzel
term_new() silently cut a scrollback above 1000000 lines to 1000000. The limit now has a name in term.h, and term_new() returns NULL above it, as it does for the other invalid options. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

10 daysReplace the writer spin lock with a blocking mutexBerke Güzel
term_write_begin spun on an atomic sequence word. A waiter burned CPU, and with no priority inheritance a SCHED_FIFO waiter could starve a preempted holder on the same CPU. The writer section is now a pthread mutex with PTHREAD_PRIO_INHERIT where the platform has it, and an SRWLOCK on Windows. Re-entry on the owning thread still only counts the depth. The platform wrapper (init, lock, unlock, destroy) is in compat.h. term_new initializes the mutex, and term_free destroys it. Meson links the thread library into the core, term_dep, and term_internal_dep. The README, term.h, and the amalgamation note say that POSIX needs -pthread. Tests: the feed and snapshot thread test now checks the final screen and history against a serial reference. A new test checks that term_lock nests and that another thread waits for the last term_unlock. Co-Authored-By: Claude Haiku 5.5 <noreply@anthropic.com>
10 daysTake the terminal name from term_options.nameBerke Güzel
The core hard-coded "wsap_term" for XTVERSION, the XTGETTCAP TN and name default, and the OSC 9 notification title. A headless library should take its identity from the host. term_options.name sets the name. NULL or "" selects "term". term_new() copies it and returns NULL unless it is 1 to 63 printable ASCII bytes, since DCS replies echo it. A DCS +p still changes the TN value, and the XTVERSION and notification defaults keep the host name. Co-Authored-By: Claude Haiku 5.5 <noreply@anthropic.com>
10 daysReject invalid arguments instead of ignoring themBerke Güzel
term_feed() returns bool and rejects a NULL terminal, a NULL buffer with a nonzero length, and any flag bit it does not know. Unknown bits are rejected now so that later flags can be added without changing what the old calls mean. term_new() returns NULL for a negative size component, columns above TERM_MAX_COLS, a negative scrollback, or a cursor style outside the enum. Zero still selects the default size and scrollback. It no longer clamps bad values silently. term_resize() rejects columns above TERM_MAX_COLS instead of clamping them, which matches how it already rejects a size below 1.

10 daysAdd soversion, version macros, and reserved term_options wordsBerke Güzel
The shared library now carries its major version in the SONAME (libterm.so.0), so an ABI break gets a new file name. The header gains TERM_VERSION, TERM_VERSION_MAJOR/MINOR/PATCH and TERM_VERSION_CODE, and term_version() returns the code the library was built with. A test checks the macros against meson.build's project version and against the runtime value. term_options ends with uint32_t reserved[8]. term_new() returns NULL if a word is nonzero, so later versions can give those words a meaning without misreading a caller's leftover data. All-zero options stay valid. Co-Authored-By: Claude Haiku 5.5 <noreply@anthropic.com>
10 daysReturn owned text and share cell attribute flags with snapshotsBerke Güzel
Make text queries return allocated strings released with term_text_free, keeping each capture atomic. Align public attributes with the write core, remove snapshot conversion tables, and migrate tests and the Kitty adapter.
10 daysFix snapshot storage and allocation failure correctnessBerke Güzel
Account for cluster records discarded by snapshot scrolling, propagate snapshot allocation failures with an empty retryable view, and allocate resized screens before mutating visible state. Add bounded-memory and allocation-failure regressions, and update the saved diagnostic and audit report.

13 daysterm: move the term core to subprojects/termBerke Güzel
The core now builds, tests, and benchmarks alone, as a Meson subproject with no dependency on the main tree. - include/term/ holds term.h and the header-only unicode/. src/ holds the core and its private headers. The main tree gets only include/term through term_dep, so it cannot reach a private header. - The term tests, the term benchmarks, the Kitty parser suite, and tools/amalgamate.py and tools/generate_unicode.py move with it. The tests run as term:<name>. - The main build passes its -march (arch_flag) and b_ndebug to the subproject. A directory configured before this commit needs meson configure -Dterm:arch_flag=-march=... once. - The term tests compile with -UNDEBUG. They do work inside assert. - The subproject exports term_test_dep with term_api.h, for the main tree's render, thumbnail, color, and selection tests. - The Kitty bridge used struct vector2i and has not compiled since the public API redesign. It builds again. 2 of its 14 tests fail: REP after a tab, and a cursor report after a resize. - dirgraph.py drops the term and unicode layers. Its self-test uses pty. - The symbols test ignores the __odr_asan symbols that ASan adds. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
