 RUNTIME NAMING (user 2026-07-21): piperepl-patched runtime executables must carry
-'punk' in the name so patched and unpatched are never confusable - e.g
-tclsh905punk.exe. The suite's current tclsh90spr/tclsh90sprzip are INTERNAL WORKING
-NAMES pending this goal's scheme. Open design questions the user flagged, to
-resolve here: how to encode BOTH the tcl patchlevel and a punk version (which punk
-version - the patch revision? the punkshell release the kit family ships with?),
-and which separators are appropriate. Existing-namespace considerations for that
-decision: kit exes use bare punk+patchlevel (punk905.exe), runtimes historically
-tclsh+nodotversion+flags (tclsh90s) or tclsh+patchlevel (tclsh905.exe), and bin
-UTILITIES use the punk- hyphen prefix (bin/AGENTS.md policy) - three deliberate
-sub-namespaces; windows-filename-safe separators only; and the G-103 metadata
-records can carry the AUTHORITATIVE versions, letting filenames stay
-human-distinguishing rather than fully version-encoded.
+'punk' in the name so patched and unpatched are never confusable. The suite's
+tclsh90spr/tclsh90sprzip stay recipe-INTERNAL working names - this goal's
+kit-assembly steps emit the public names below at the boundary.
+
+NAMING DECISION (user-approved 2026-07-21; resolves the acceptance's
+tcl-patchlevel / punk-version / separator questions). Principle: two naming
+tiers, mapped by tooling - punkbin stores immutable fully-qualified ARTIFACT
+names; projects and fingers consume short stable WORKING names; 'runtime use'
+(punk-runtime after G-097) and mapvfs are the mapping.
+
+- RUNTIME ARTIFACT names (punkbin tier; rarely typed, verbosity fine):
+  tclsh<dotted-tcl-patchlevel>[-punk[-bi]]-r<N>(.exe) - e.g tclsh9.0.5-r1.exe
+  (plain member), tclsh9.0.5-punk-r1.exe, tclsh9.0.5-punk-bi-r1.exe. Dotted
+  patchlevels are REQUIRED (tclsh1005 is unreadable/ambiguous once Tcl 10 and
+  9.0.10-class patchlevels exist). -r<N> is an ASSEMBLY REVISION per
+  (patchlevel, variant), ALWAYS present for uniform parsing, incremented on any
+  republish of the same patchlevel (battery bump, patch fix, toolchain bump) -
+  artifacts are immutable and coexist for rollback. NO punkshell version and NO
+  patch revision in runtime names: runtimes carry no punkshell modules, and the
+  metadata record is authoritative for patch revision, component versions,
+  source pins and toolchain.
+- RUNTIME WORKING names (what mapvfs references; bin/runtime/<target>/): the
+  artifact name minus -r<N> - e.g tclsh9.0.5-punk.exe; 'runtime use'
+  materializes a chosen -rN artifact into it, so republishing never churns
+  consumers.
+- KIT names flip the release axis to the PUNKSHELL version (the kit's payload):
+  typable WORKING names are major-only - punk9, punk8, variant punk9bi -
+  precision stamped in-file/metadata; published/archived KIT ARTIFACTS are
+  punk<major>-<punkshellversion>(.exe) - e.g punk9-0.5.0.exe, prerelease
+  punk9-0.5.0b2.exe. Two punk9 releases may differ in tcl patchlevel - that is
+  metadata's job. The dev-matrix style (punk905, punk902z - tcl patchlevel
+  encoded, owner-chosen via mapvfs, typed constantly while comparing runtimes)
+  remains a recognized third style; kit conventions here are documented
+  DEFAULTS, not mandates - kit exe naming stays under project-owner control.
+- Separators: hyphens throughout (safe here - these names neither start with
+  punk- nor live on PATH, so the bin-utility prefix convention is not in play);
+  '+' banned (hostile in raw punkbin URLs); '_' reserved as fallback. Filenames
+  IDENTIFY; ORDERING comes from runtime list parsing metadata (lexicographic
+  sort misorders tclsh10.* before tclsh9.* regardless of dots) - per-series
+  punkbin subdirs remain a later option.
+
+(The acceptance's 'e.g tclsh905punk.exe' example predates this decision; the
+decided punk-marked shape is tclsh<dotted-patchlevel>-punk....)
