 ```
 
 These lines carry zero information for the reader — the injected content was consumed by the AI in that session, and its conclusions already appear in the subsequent assistant messages. Showing 4 redundant lines wastes output space and context tokens when the output is fed back into another session.
 
 ## Decision
 
-Collapse consecutive `cc-session inject/read/context` Bash tool calls targeting the same session into a single descriptive line:
+Collapse consecutive `cc-session inherit/read/context` Bash tool calls targeting the same session into a single descriptive line:
 
 ```
-(cc-session: injected session 16d06326 here, 1320 lines omitted)
+(cc-session: inherited session 16d06326 here, 1320 lines omitted)
 ```
 
 The collapsing is:
 - **Automatic** — no flag required. The original tool call details remain accessible via `cc-session expand <session> <tool-id>`.
 - **Scoped to cc-session CLI calls only** — other Bash tool calls (including the model fumbling with `which cc-session`, `node cc-session.mjs`, etc.) render normally as one-line summaries.
 - **Applied in both `read` and `context` output formats** — the collapsing logic lives in a shared `collapseCCSessionTools()` function called by both renderers' flush paths.
+- **Backward compatible with `inject`** — older transcripts recorded before the `inject` → `inherit` CLI rename still contain literal `cc-session inject` calls. Those still collapse the same way, keeping their historical "injected" wording so old sessions read naturally.
 
 ### Detection
 
-`parseCCSessionCommand(cmd)` checks if a Bash command matches `cc-session {inject|read|context} <session-id>`. It returns the subcommand and an 8-char session ID prefix. Args starting with `-` (flags like `-h`) are rejected to avoid false positives.
