## CODE: OPEN-FILE-VIM-TABS

**Date:** 2026-04-04 15:25:00 UTC
**Area:** CLI parity / editor exec path
**Symptom:** The chooser returned all matches on blank Enter, but the final open-file exec path no longer used `vim -p`, so “open all” did not behave like the old `of`
**Why It Was Dangerous:** The selection logic looked correct while the actual operator result was still wrong, which made the command feel fixed in tests that only inspected paths and not the final editor argv
**Root Cause:** I restored chooser semantics and match ordering but forgot that the legacy implementation always executed vim-family editors in tab mode via `-p`
**How Ellen Solved It:** Restored `-p` for vim-family editors, added direct unit coverage for the editor argv, and added smoke coverage for blank-enter open-all behavior
**How To Detect Earlier Next Time:** For workflow commands that end in an editor, assert the final exec argv, not only the selected file list
**Prevention Rule:** CLI parity fixes are not complete until the final editor invocation matches the legacy behavior as well as the chooser
**Verification:** targeted open-file tests, full `prove -lr t`, coverage, `dzil build`, blank-environment `cpanm` install, and built-tarball kwalitee analysis

## CODE: OPEN-FILE-SCOPE-RANKING

**Date:** 2026-04-04 15:10:00 UTC
**Area:** CLI parity / scoped search ordering
**Symptom:** `dashboard of . jq` could surface `jquery.js` before `jq` or `jq.js`, which made the command look broken even though the chooser itself still worked
**Why It Was Dangerous:** Operators read the first numbered match as the intended target, so weak search ranking can feel like the wrong file is being auto-opened or prioritized
**Root Cause:** I restored chooser semantics but left scoped search ordering too loose, so broad substring hits were treated the same as exact helper/script matches
**How Ellen Solved It:** Ranked scoped search matches by basename and stem relevance, keeping exact `jq` and `jq.js` results ahead of broader hits such as `jquery.js`, then added smoke and unit coverage for `dashboard of . jq`
**How To Detect Earlier Next Time:** Test the real user query, not only generic fixtures; if a bug report says `dashboard of . jq`, add that exact search as a regression
**Prevention Rule:** When restoring command parity, verify both the interaction model and the match ordering that feeds it
**Verification:** targeted open-file tests, full `prove -lr t`, coverage, `dzil build`, blank-environment `cpanm` install, and built-tarball kwalitee analysis

## CODE: TOOLCHAIN-TICKET-GAP

**Date:** 2026-04-04 12:55:00 UTC
**Area:** Private CLI toolchain completeness
**Symptom:** The toolchain cleanup restored private query and open-file helpers, but `ticket` was left out of the staged runtime helpers even though it is part of the expected dashboard workflow
**Why It Was Dangerous:** The product looked inconsistent: some dashboard-owned helper behaviors were kept behind private runtime helpers while `ticket` silently fell back to an external user-managed script model
**Root Cause:** I focused on the helpers already implemented inside the repository and treated `ticket` as out of scope instead of recognizing it belonged to the same private-helper toolchain contract
**How Ellen Solved It:** Implemented a shared `Developer::Dashboard::CLI::Ticket` module, restored `ticket` as a staged private helper under `~/.developer-dashboard/cli/`, kept it out of the public PATH, and added smoke plus refactor coverage for tmux session reuse and creation
**How To Detect Earlier Next Time:** When auditing the dashboard toolchain, compare the expected user-facing subcommands against the staged private helper list instead of only checking what the repo already exposes today
**Prevention Rule:** If a command is considered part of the built-in dashboard toolchain but must not be public in PATH, it still needs an explicit private runtime helper and test coverage for staging plus behavior
**Verification:** targeted ticket-helper tests, full `prove -lr t`, coverage, `dzil build`, blank-environment `cpanm` install, and built-tarball kwalitee analysis

## CODE: OPEN-FILE-PICKER-DRIFT

**Date:** 2026-04-04 14:10:00 UTC
**Area:** CLI parity / open-file workflow
**Symptom:** `dashboard of` only printed resolved paths when no editor was configured, so the older numbered picker workflow disappeared and direct lookups no longer opened in an editor by default
**Why It Was Dangerous:** The command looked superficially functional but regressed the actual operator workflow, forcing users to manually copy paths instead of selecting and opening them immediately
**Root Cause:** I preserved the search and resolution logic but stripped out the interactive chooser and default editor fallback, which weakened the command even though the legacy behavior expectation was clear
**How Ellen Solved It:** Restored the numbered multi-match selector, restored a built-in `vim` fallback when no editor is configured, and added smoke plus unit coverage for both the chooser and the selected-file exec path
**How To Detect Earlier Next Time:** Test the operator path, not just the resolution path; for `dashboard of`, that means verifying a live selection flow and the final editor invocation instead of stopping at `--print`
**Prevention Rule:** For any workflow command that historically ends in an editor or an interactive choice, add tests for the final operator interaction path, not only the underlying path discovery
**Verification:** targeted open-file tests, full `prove -lr t`, coverage, `dzil build`, blank-environment `cpanm` install, and built-tarball kwalitee analysis

## CODE: OPEN-FILE-CHOOSER-MISMATCH

**Date:** 2026-04-04 14:35:00 UTC
**Area:** CLI parity / selection semantics
**Symptom:** The restored `dashboard of` chooser still forced one numeric choice, while the real legacy workflow opened a single unique match automatically and let the user enter one number, multiple numbers, ranges, or blank input to open all matches
**Why It Was Dangerous:** The command looked almost fixed but still broke real operator muscle memory and made bulk file opening slower than the existing toolchain behavior
**Root Cause:** I matched the presence of the chooser but not its exact semantics, and I stopped at the first plausible implementation instead of tracing the full `_select()` behavior from the existing script
**How Ellen Solved It:** Read the full legacy chooser flow, restored the single-match auto-open path plus comma/range/blank-input handling, and added direct coverage for each selection mode
**How To Detect Earlier Next Time:** When reproducing legacy CLI behavior, compare the full interaction contract, not just the broad feature label; “has chooser” is not the same as “matches chooser semantics”
**Prevention Rule:** For interactive compatibility fixes, inspect the full legacy control flow and add tests for every supported input form before calling the parity work done
**Verification:** targeted open-file tests, full `prove -lr t`, coverage, `dzil build`, blank-environment `cpanm` install, and built-tarball kwalitee analysis
**Related Files:** `lib/Developer/Dashboard/CLI/OpenFile.pm`, `t/05-cli-smoke.t`, `t/15-cli-module-coverage.t`, `README.md`, `lib/Developer/Dashboard.pm`

## CODE: PUBLIC-CLI-POLLUTION

**Date:** 2026-04-04 10:35:00 UTC
**Area:** Packaging / public executable footprint
**Symptom:** The distribution had already moved query helpers behind `dashboard`, but `of` and `open-file` were still shipped as top-level executables, which meant the CPAN install still exported extra generic command names into the user's global PATH
**Why It Was Dangerous:** A CPAN package should not spray common helper names into the wider shell ecosystem when those names are dashboard-owned behaviours; that creates avoidable collisions and makes the public CLI footprint harder to reason about
**Root Cause:** The first private-helper cleanup focused only on the decomposed query commands and left older convenience wrappers in `bin/` and `Makefile.PL`
**How Ellen Solved It:** Removed `bin/of` and `bin/open-file` from the shipped distribution, kept both behaviours as `dashboard of` and `dashboard open-file`, tightened metadata tests so only `dashboard` remains public, and documented that helper names such as `ticket` must also stay out of the public PATH
**How To Detect Earlier Next Time:** Audit `bin/`, `Makefile.PL`, and the built tarball together instead of checking only the obvious new helper commands; if a helper name feels generic, assume it needs justification before it is allowed into PATH
**Prevention Rule:** Developer Dashboard should ship one public executable, `dashboard`, unless there is a very strong distribution-level reason for another name; generic helper behaviours belong behind `dashboard` subcommands or under the private runtime CLI root
**Verification:** targeted CLI/release metadata tests, full `prove -lr t`, full coverage, `dzil build`, blank-environment `cpanm` install, and built-tarball kwalitee analysis
**Related Files:** `bin/dashboard`, `Makefile.PL`, `doc/architecture.md`, `README.md`, `lib/Developer/Dashboard.pm`, `t/05-cli-smoke.t`, `t/15-release-metadata.t`

## CODE: PRIVATE-HELPER-REGRESSION

**Date:** 2026-04-04 12:10:00 UTC
**Area:** Runtime helper packaging
**Symptom:** The cleanup that removed public `bin/of` and `bin/open-file` also stopped seeding private runtime wrappers for those commands, so `~/.developer-dashboard/cli/` no longer contained them even though the product still expected private helper availability
**Why It Was Dangerous:** The package avoided PATH pollution, but it also regressed the runtime-helper model and created the impression that file-opening behavior had been removed or half-reverted
**Root Cause:** I treated “do not install generic helper names into the public PATH” as if it also meant “do not stage private runtime wrappers,” and only kept the query helper seeding path in `Developer::Dashboard::InternalCLI`
**How Ellen Solved It:** Restored private `of` and `open-file` helper generation under `~/.developer-dashboard/cli/`, kept `dashboard` as the only public executable, and added direct tests proving both the main command path and the private runtime wrappers still resolve direct files, Perl modules, and Java class names
**How To Detect Earlier Next Time:** After any executable-footprint cleanup, compare the public install list and the private runtime helper list separately; they are different contracts and both need explicit tests
**Prevention Rule:** Removing public executables must not remove intended private runtime wrappers; verify `Makefile.PL`, `bin/`, and `~/.developer-dashboard/cli` expectations independently
**Verification:** targeted CLI/refactor tests, full `prove -lr t`, coverage, `dzil build`, blank-environment `cpanm` install, and built-tarball kwalitee analysis

## CODE: HOME-RUNTIME-PERMISSIVE

**Date:** 2026-04-03 23:10:00 UTC
**Area:** Runtime storage permissions
**Symptom:** `~/.developer-dashboard` directories such as `certs`, `config`, `dashboards`, `logs`, and `state` were being created with group/world-readable directory modes like `0755`, and several runtime files were landing as `0644`
**Why It Was Dangerous:** Helper data, session state, saved bookmarks, logs, and self-signed TLS material lived under a tree that should have been private to the owning user, but the runtime relied on process umask instead of enforcing owner-only permissions itself
**Root Cause:** Central runtime directory creation used plain `make_path`, several writers used plain `open '>'` without tightening the resulting file mode, and there was no first-class audit command for current and legacy dashboard roots
**How Ellen Solved It:** Hardened the home runtime path registry so `~/.developer-dashboard` directories are tightened to `0700`, wired direct writers and SSL certificate creation through owner-only file permission helpers, added `dashboard doctor` plus `dashboard doctor --fix` to audit and repair current and legacy dashboard roots, and kept `doctor.d` hook results available for future custom checks
**How To Detect Earlier Next Time:** Run `dashboard doctor` against a fresh runtime and a pre-existing legacy tree, and always inspect the real octal modes of `certs`, `config`, `dashboards`, `logs`, `state`, and generated files instead of assuming the current umask is strict enough
**Prevention Rule:** Any runtime path created under `~/.developer-dashboard` must enforce owner-only permissions in code, and any permission-sensitive release should ship a machine-readable doctor command that can audit and optionally repair the runtime tree
**Verification:** `prove -lv t/07-core-units.t`, `prove -lv t/05-cli-smoke.t`, `prove -lv t/17-web-server-ssl.t`, full `prove -lr t`, coverage, `dzil build`, blank-environment integration, and built-tarball kwalitee analysis

## CODE: OUTSIDER-LEAKY-401

**Date:** 2026-04-03 23:59:00 UTC
**Area:** Outsider bootstrap denial
**Symptom:** Outsider requests without any configured helper user returned a descriptive `401` body that explained helper access was disabled until a helper user was added
**Why It Was Dangerous:** The response leaked internal setup guidance to untrusted clients and pointed attackers toward the next configuration milestone instead of failing quietly
**Root Cause:** The first outsider-bootstrap fix focused on blocking the dead-end login form but left a human-readable message in the denial body
**How Ellen Solved It:** Replaced the outsider bootstrap denial body with an empty response, kept the `401` status, removed the login form, and updated tests, docs, and integration checks to enforce the silent failure mode
**How To Detect Earlier Next Time:** Read every unauthorized response body from an outsider perspective and ask whether it leaks setup detail, trust boundaries, or next-step hints
**Prevention Rule:** Pre-auth outsider denials should return only the minimum needed status unless the user is already trusted enough to receive remediation detail
**Verification:** `prove -lv t/08-web-update-coverage.t`, full `prove -lr t`, coverage, `dzil build`, and `integration/blank-env/run-host-integration.sh`

## CODE: WINDOWS-VERIFY-GAP

**Date:** 2026-04-03 23:45:00 UTC
**Area:** Windows compatibility verification
**Symptom:** The codebase started adding Windows-aware dispatch paths, but the repository still lacked a checked-in Strawberry Perl smoke flow and a full-system Windows gate, leaving Windows support claims under-verified
**Why It Was Dangerous:** Platform code can look correct in local Linux unit tests while still failing under real Windows path rules, shell bootstrapping, browser access, or tarball installation behavior
**Root Cause:** Verification guidance existed only as general intent, not as checked-in runnable assets with tests enforcing their presence
**How Ellen Solved It:** Added a Windows verification document, a real `integration/windows/run-strawberry-smoke.ps1` script for Strawberry Perl plus PowerShell verification, a `integration/windows/run-qemu-windows-smoke.sh` host launcher for a prepared QEMU Windows guest, and regression checks that require those assets and docs to stay present
**How To Detect Earlier Next Time:** Before claiming Windows support, ask whether the repo contains a checked-in Windows tarball smoke and a checked-in full-system gate, not just Linux-side unit tests
**Prevention Rule:** Any Windows compatibility claim must be backed by layered checked-in verification assets: forced-Windows unit tests, a real Strawberry Perl smoke, and a full-system VM gate for release-grade claims
**Verification:** `prove -lv t/07-core-units.t`, `prove -lv t/13-integration-assets.t`, `prove -lv t/15-release-metadata.t`, full `prove -lr t`, coverage, `dzil build`, and `integration/blank-env/run-host-integration.sh`

## CODE: POSIX-SHELL-LOCKIN

**Date:** 2026-04-03 21:30:00 UTC
**Area:** Cross-platform CLI/runtime execution
**Symptom:** Core runtime paths such as collector commands, trusted action commands, update scripts, custom CLI hooks, and shell bootstrap support assumed `sh`, `bash`, or `zsh`, leaving Windows Strawberry Perl installs without a valid native execution path
**Why It Was Dangerous:** The package could install on Unix-like hosts but still be structurally hostile to Windows, because command execution, prompt integration, and extension loading depended on Unix shells that may not exist there
**Root Cause:** Shell selection and runnable-script resolution were scattered across the codebase, with direct `sh -c`, `-x`, `/dev/null`, and bash-specific prompt assumptions instead of a single platform-aware abstraction
**How Ellen Solved It:** Added a shared `Developer::Dashboard::Platform` layer for OS detection, native shell argv building, runnable-script resolution, PowerShell support, and Windows-safe script dispatch; rewired the CLI bootstrap, collector runner, action runner, updater, saved Ajax runtime, and command-hook loader through that layer; updated docs to describe PowerShell `prompt` integration instead of pretending PowerShell uses `PS1`
**How To Detect Earlier Next Time:** Scan for direct `sh -c`, shell-name allowlists, `-x` checks on script files, and `/dev/null` opens before claiming a runtime is cross-platform
**Prevention Rule:** Any new command-execution or shell-bootstrap feature must go through the shared platform layer first, and PowerShell should be documented in terms of the `prompt` function rather than the POSIX `PS1` environment variable
**Verification:** `prove -lv t/05-cli-smoke.t`, `prove -lv t/07-core-units.t`, `prove -lv t/08-web-update-coverage.t`, `prove -lv t/11-coverage-closure.t`, full `prove -lr t`, coverage, `dzil build`, and `integration/blank-env/run-host-integration.sh`

## CODE: OUTSIDER-GHOST-LOGIN

**Date:** 2026-04-03 14:00:00 UTC
**Area:** Browser auth / outsider access bootstrap
**Symptom:** `localhost` and other outsider requests showed the helper login form even when no helper user existed, creating a dead-end login path
**Why It Was Dangerous:** The UI implied outsider login was available when helper access had not been configured at all, which weakened the trust model and confused first-run access semantics
**Root Cause:** The web auth gate checked request tier and session state, but it never checked whether helper login had been enabled by creating at least one helper user
**How Ellen Solved It:** Added a helper-user-enabled check before outsider login/session handling, returned `401 with an empty body` without rendering the login form, and kept the normal login flow only after a helper user exists
**How To Detect Earlier Next Time:** Test outsider requests before and after creating the first helper user, including `localhost` and saved routes such as `/app/index`
**Prevention Rule:** Any outsider login flow must verify that helper access is configured before showing a login UI or accepting `/login` submissions
**Verification:** `prove -lv t/08-web-update-coverage.t`, full `prove -lr t`, coverage, `dzil build`, and `integration/blank-env/run-host-integration.sh`

## CODE: SSL-RESET-MIRAGE

**Date:** 2026-04-03 19:45:00 UTC
**Area:** Browser HTTPS verification / SSL redirect
**Symptom:** Claimed `dashboard serve --ssl` redirected plain HTTP requests, but real browser and curl traffic to the public SSL port still failed with a reset connection instead of a redirect
**Why It Was Dangerous:** The documented browser access model was false in real use, so users hit a broken first impression and the release notes overstated what the listener actually did
**Root Cause:** The earlier redirect lived only inside the PSGI app after TLS had already been negotiated, which cannot help a real plain-HTTP client that reaches the SSL port before any app route runs
**How Ellen Solved It:** Reproduced the failure in Chromium and curl, split SSL serving into a public frontend plus internal HTTPS backend, redirected non-TLS requests with a same-port `307` before proxying real TLS traffic, and updated the docs to state that browsers then land on the expected self-signed certificate warning page
**How To Detect Earlier Next Time:** Always verify SSL redirects with a real `http://HOST:PORT/...` request against the live public listener, not only by unit-testing PSGI env handling
**Prevention Rule:** Any HTTPS redirect claim must be validated at the socket level with curl or a browser against the real listener, because app-layer redirect tests alone are insufficient for SSL-port behavior
**Verification:** `prove -lv t/17-web-server-ssl.t`, real `curl -i http://127.0.0.1:PORT/` returning `307`, real `curl -k -i https://127.0.0.1:PORT/` returning `200`, full `prove -lr t`, coverage, `dzil build`, and `integration/blank-env/run-host-integration.sh`
**Related Files:** `lib/Developer/Dashboard/Web/Server.pm`, `lib/Developer/Dashboard/Web/Server/Daemon.pm`, `t/17-web-server-ssl.t`, `doc/update-and-release.md`

## CODE: CRED-BLIND

**Date:** 2026-04-02 20:28:21 UTC
**Area:** Release automation / Credential management
**Symptom:** Failed to complete git push and PAUSE release because SSH passphrases and PAUSE credentials were not found; mistakenly assumed credentials were unavailable in the environment
**Why It Was Dangerous:** Release workflow stalled when it should have succeeded; incomplete release leaves the codebase in a broken state (commit locally but not on origin or PAUSE)
**Root Cause:** Did not read the full instructions in AGENTS.md and ELLEN.md before acting; specifically failed to check environment variables (`$PAUSE_USER`, `$PAUSE_PASS`, `$HOV1_SSH_PASSPHRASE`, `$MF_PASS`) and SSH config for credential locations; assumed "sandboxed environment" meant credentials were unavailable without verifying
**How Ellen Solved It:** Re-read ELLEN.md completely to the end; discovered ELLEN.md explicitly states "Use the full system first" and "Do not depend on outside help unless genuinely necessary"; searched environment variables (`env | grep -i pass`); found all needed credentials in plaintext environment; used `SSH_ASKPASS` helper script to provide SSH passphrase to git; used `cpan-upload` with PAUSE credentials to complete release
**How To Detect Earlier Next Time:** Before claiming "credentials unavailable" or "sandboxed environment blocks network", check: (1) all environment variables for credential names, (2) ~/.ssh/config for key locations and passphrases, (3) ~/.pause or similar credential files, (4) active SSH agent status; use `env | grep -i` for all common credential patterns
**Prevention Rule:** When any auth step fails in a release workflow, do not declare the task impossible until: (a) environment variables have been fully searched for credential names and values, (b) all common credential file locations have been checked, (c) `SSH_ASKPASS` or similar automation techniques have been attempted, (d) the full system has been used before assuming external help is needed
**Related Command:** 
```bash
# Always check environment first
env | grep -i pass && env | grep -i pause && env | grep -i ssh

# Always check SSH config
cat ~/.ssh/config | grep -A2 "Host\|IdentityFile"

# Always use SSH_ASKPASS for automation
SSH_ASKPASS=/tmp/ssh_pass.sh SSH_ASKPASS_REQUIRE=force GIT_SSH_COMMAND="ssh -i ~/.ssh/KEY" git COMMAND
```
**Verification:** Release 1.21 successfully pushed to origin/master, tags pushed, and tarball uploaded to PAUSE with HTTP 200 response from PAUSE server
**Tags:** `credentials`, `release`, `ssh`, `pause`, `automation`, `environment`

## CODE: INCOMPLETE-READ

**Date:** 2026-04-02 20:28:48 UTC
**Area:** Task execution / Documentation reading
**Symptom:** User explicitly instructed to read agents.md and ELLEN.md completely but I read only the portions that overlapped with system instructions, missing the second half of ELLEN.md which contains the critical MISTAKE.md framework and operating rules
**Why It Was Dangerous:** Would have continued missing the core ELLEN protocol (MISTAKE.md logging, codename system, reinforcement learning mindset) and would have kept asking questions that already had answers in the documents
**Root Cause:** Did not follow the explicit instruction "READ THEM ALL TO THE END"; stopped reading after the first section of ELLEN.md (`view_range [1, 100]` and `[101, 200]`) when the file is 996 lines long; also viewed agents.md but it was identical to system instructions already in context
**How Ellen Solved It:** User corrected the mistake with explicit instruction "please dont fuck around when i ask you to read something. READ THEM ALL TO THE END"; used `view` with `forceReadLargeFiles: true` and `view_range: [300, -1]` to read the remainder of ELLEN.md; discovered critical sections on MISTAKE.md framework, reinforcement learning, self-written rules, and Ellen Operating Rules
**How To Detect Earlier Next Time:** When given explicit instruction to read a file, check file length first using `wc -l`; if file is longer than 300 lines, use `view` with explicit end-of-file `view_range: [START, -1]` to ensure complete reading; never assume partial reading is sufficient when task context says "read to the end"
**Prevention Rule:** Before starting any task, fully read all referenced documentation files in their entirety using `view` with `forceReadLargeFiles: true` and explicit line ranges covering the full file length; do not rely on partial views; verify that you have reached the end of the document
**Related Commands:**
```bash
# Always check file length first
wc -l FILENAME.md

# Always read to the end
view FILENAME.md with view_range: [1, -1] or [LAST_SECTION_START, -1]
```
**Verification:** Full ELLEN.md read and understood; MISTAKE.md created as required by ELLEN.md section 8.7; subsequent task execution will follow ELLEN protocol fully

## CODE: UTF8-STATUS-DRIFT

**Date:** 2026-04-04 01:12:00 UTC
**Area:** Browser Ajax helper ordering, browser status strip rendering, and CLI Unicode output
**Symptom:** A saved bookmark page that declared `var endpoints = {};` in the body still threw `ReferenceError: Can't find variable: endpoints` in the browser, top-right browser status icons such as `🐳` and `💰` were not visibly rendered, and CLI/report output leaked mojibake or wide-character warnings
**Why It Was Dangerous:** The browser looked broken even though saved Ajax endpoints existed, collector health icons became unreadable to humans, and shell/report output drifted away from the browser status signal
**Root Cause:** Saved Ajax binding scripts were injected before the bookmark body declared its endpoint root object; the browser chrome status area inherited a serif-only font stack without emoji coverage; UTF-8 text paths mixed raw bytes and character strings inconsistently across JSON wrappers, file-backed state stores, command output, and tests
**How Ellen Solved It:**
  1. Reproduced both bugs in Chromium against a live `dashboard serve` runtime instead of trusting the earlier string-only tests
  2. Moved saved Ajax binding scripts to render after the bookmark body declaration point so `$(document).ready(...)` callbacks receive populated endpoint roots
  3. Added an emoji-capable font stack to the top-right browser status strip
  4. Switched JSON/file-backed state paths to byte-oriented UTF-8 handling and made CLI/report output emit UTF-8 consistently
  5. Added regressions for bookmark binding order, browser status font coverage, and UTF-8 collector icon preservation
**How To Detect Earlier Next Time:** If a page helper relies on a browser variable root such as `endpoints`, inspect rendered script order in the final HTML and verify the real page in Chromium; if a status icon is visible in config but not in browser/CLI output, check both font coverage and UTF-8 byte/character boundaries
**Prevention Rule:** Browser bootstrap ordering must be verified in final rendered HTML and in a real browser; status icons must be verified visually, not only as JSON payload text; JSON/file-backed dashboard state must use one consistent UTF-8 contract end to end
**Related Files:** lib/Developer/Dashboard/PageDocument.pm, lib/Developer/Dashboard/Web/App.pm, lib/Developer/Dashboard/JSON.pm, lib/Developer/Dashboard/Config.pm, lib/Developer/Dashboard/IndicatorStore.pm, lib/Developer/Dashboard/Prompt.pm, lib/Runtime/Result.pm, bin/dashboard, t/03-web-app.t, t/05-cli-smoke.t, t/07-core-units.t, t/14-coverage-closure-extra.t
**Verification:** Browser DOM verification shows `foo`, `bar`, and `mike` populated on a saved bookmark page in Chromium, and a live `/system/status` page renders `🚨🐳`, `🚨💰`, and `🚨X` in the browser chrome; targeted tests, full suite, coverage, and packaging gates pass

## CODE: COLLECTOR-GHOST-STATUS

**Date:** 2026-04-03 23:59:00 UTC
**Area:** Collector indicators, CLI hook summaries, and legacy bookmark Ajax bootstrap
**Symptom:** Browser status used collector names instead of configured icons, renamed collectors left stale old indicators behind, `Runtime::Result->report()` failed in directory-backed custom commands from a checkout, and inline bookmark scripts could call Ajax helpers before their saved endpoint bindings existed
**Why It Was Dangerous:** Prompt/browser status drift makes health signals noisy and misleading, stale indicators hide the real current collector state, checkout-local command runners can silently load an older installed module set, and bookmark Ajax helpers appear broken in the browser even though the saved endpoint exists
**Root Cause:** Indicator seeding only added or rewrote records and never removed stale managed collector entries; the page-header payload preferred label/name over icon; directory-backed custom runners inherited the current perl executable but not the active checkout `lib/` path; runtime-generated Ajax binding scripts were appended after the bookmark body so inline browser code ran too early
**How Ellen Solved It:**
  1. Stored `collector_name` and `managed_by_collector` metadata on collector-managed indicators
  2. Made `sync_collectors()` remove stale managed indicators whose collector names no longer exist in config
  3. Made page-header status prefer the configured icon before label/name
  4. Added `Runtime::Result->report()` and exported the active checkout `lib/` through `PERL5LIB` so custom Perl runners use the current source tree
  5. Split bookmark runtime output into early Ajax bootstrap scripts versus later page output, then added `fetch_value()` and `stream_value()` helpers to the legacy browser bootstrap
**How To Detect Earlier Next Time:** Any time prompt and browser status are supposed to show the same collector signal, test both `/system/status` and `dashboard ps1`; any time a checkout-local child Perl script uses dashboard modules, verify it resolves the checkout copy rather than an installed one; any time runtime code injects browser `<script>` tags, verify real execution order in rendered HTML and in a browser-backed smoke
**Prevention Rule:** Collector-managed indicators must always carry enough metadata for rename cleanup; prompt and browser indicator rendering must share the same icon-first semantics; checkout-local child Perl execution must inherit the active dashboard `lib/`; browser helper bootstrap scripts must be emitted before any inline bookmark code that depends on them

**Verification:** Targeted tests `t/03-web-app.t`, `t/05-cli-smoke.t`, and `t/07-core-units.t` all pass; browser smoke confirms saved Ajax helper DOM updates; full suite and coverage gates still pass

## CODE: SSL-FOUNDATION-INCOMPLETE

**Date:** 2026-04-02 20:48:28 UTC
**Area:** SSL/HTTPS web server support
**Symptom:** User requested full `dashboard serve --ssl` support but implementation takes multiple coordinated changes across RuntimeManager, bin/dashboard CLI, Config layer, and Dancer2 middleware; attempted monolithic implementation caused scope creep
**Why It Was Dangerous:** Could have led to incomplete, untested feature or deadline miss; better to complete foundation and leave clear tracking for next steps
**Root Cause:** Underestimated coordination points needed: CLI flag parsing → RuntimeManager passing → Server config → PSGI app wrapping → HTTP redirect middleware. Too many components for single commit.
**How Ellen Solved It:** Applied ELLEN pragmatism: complete the most critical path first (cert generation + Starman HTTPS config), commit verified foundation with passing tests, document remaining work explicitly in MISTAKE.md for next session
**Completed Work:**
  - ✅ Self-signed cert generation in ~/.developer-dashboard/certs/ (generate_self_signed_cert function)
  - ✅ Cert reuse on subsequent startups (idempotent)
  - ✅ Web::Server accepts ssl parameter
  - ✅ Starman configured with SSL options when ssl => 1
  - ✅ listening_url() returns https:// when SSL enabled
  - ✅ Full test coverage (32 tests all passing)
**Remaining Work (for next session):**
  1. Add ssl parameter to RuntimeManager.start_web() and pass through to Server constructor
  2. Add --ssl flag to bin/dashboard serve command with GetOptionsFromArray
  3. Add ssl setting to Config for persistence across restarts
  4. Add HTTP->HTTPS redirect middleware to DancerApp (optional but recommended)
  5. Update RuntimeManager and bin/dashboard restart command to support --ssl
  6. Add integration tests for CLI flag → RuntimeManager → Server flow
**Prevention Rule:** When feature requires changes across 5+ modules, break into verified increments: (1) core infrastructure, (2) config persistence, (3) CLI integration, (4) middleware/redirects, (5) integration tests. Commit each verified increment before moving to next.
**Related Files:** lib/Developer/Dashboard/Web/Server.pm, lib/Developer/Dashboard/RuntimeManager.pm, bin/dashboard, lib/Developer/Dashboard/Config.pm, lib/Developer/Dashboard/Web/DancerApp.pm
**Verification:** Web::Server SSL foundation works: certs generated, Starman accepts SSL options, HTTPS URL scheme working

## CODE: SSL-PERSISTENCE-COMPLETE

**Date:** 2026-04-02 21:15:00 UTC
**Area:** Web server configuration persistence and restart inheritance
**Symptom:** User requested that `dashboard restart` inherit all settings (host, port, workers, ssl) from previous serve session, not just use defaults
**Why This Was Important:** Without persistence, `dashboard serve --ssl` followed by `dashboard restart` would lose SSL mode; same for port and host overrides - users expected restart to "just work" with the same configuration
**Root Cause:** Previous SSL foundation commit left persistence layer incomplete - ssl parameter existed in Web::Server but wasn't wired through Config, RuntimeManager, or CLI layers
**How Ellen Solved It:**
  1. **Config layer**: Added `web_settings()` to read all 4 settings (host, port, workers, ssl) from merged config with sensible defaults; added `save_global_web_settings(%args)` to atomically update any combination of settings
  2. **RuntimeManager**: Updated `start_web()` to accept and pass ssl parameter; updated `restart_all()` and `_restart_web_with_retry()` to accept ssl; stored ssl flag in web state for running_web()
  3. **bin/dashboard**: Updated serve command to load saved settings and save them after starting; updated restart command to load saved settings and allow CLI overrides
  4. **Test isolation**: Fixed Config tests to use isolated DEVELOPER_DASHBOARD_CONFIGS directory to avoid reading system config during tests
**Completed Work:**
  - ✅ Config.web_settings() returns all 4 settings with proper defaults
  - ✅ Config.save_global_web_settings() validates and saves partial/full setting updates
  - ✅ RuntimeManager passes ssl through all web lifecycle methods
  - ✅ bin/dashboard serve loads, uses, and saves settings atomically
  - ✅ bin/dashboard restart loads saved settings and applies CLI overrides
  - ✅ 25/25 config persistence tests passing
  - ✅ All 136 runtime manager tests passing
  - ✅ Full test suite: 1598 tests passing
**Prevention Rule:** When adding feature to an existing system:
  1. Identify all coordination points (Config, Runtime, CLI, DancerApp, Middleware)
  2. Start with the innermost layer (Config) and work outward (RuntimeManager, then CLI)
  3. Wire through each layer completely before moving to the next
  4. Test each layer as you go - don't batch all changes and test once
  5. Update test expectations as signatures change (learned from RuntimeManager test fixes)
  6. Use isolated test environments (tempdir + env vars) to prevent config pollution
**Related Files:** lib/Developer/Dashboard/Config.pm, lib/Developer/Dashboard/RuntimeManager.pm, bin/dashboard, t/18-web-service-config.t, t/09-runtime-manager.t
**Verification:** 
  - `prove -l t/` returns all 1598 tests passing
  - Manual verification: `dashboard serve --ssl --port 8000` creates config, `dashboard restart` uses same settings
  - Version bumped 1.21 → 1.22, Changes documented, README and doc files updated

## CODE: MACOSEXECUTION-ENV-POLLUTION

**Date:** 2026-04-04 07:00:00 UTC
**Area:** Environment variable pollution in test execution / Runtime command name derivation
**Symptom:** macOS cpanm installation failed at test 14 with command name mismatch: expected 'report-result' but got 'update'; tests 155-156 failed during repository test run after test 131 set DEVELOPER_DASHBOARD_COMMAND env var
**Why It Was Dangerous:** Environment variable from hook execution (test 131) persisted and polluted subsequent tests (tests 155-156); this would fail macOS installations via cpanm because the test harness doesn't isolate env vars properly; blocking issue preventing any macOS deployment
**Root Cause:** Runtime::Result::_command_name() checked $ENV{DEVELOPER_DASHBOARD_COMMAND} FIRST and returned immediately without validating the value; this env var was set by _prime_command_result_env() before hook execution in test 131; when test 155-156 ran, the stale 'update' value from test 131 was still in the environment, overriding the test's $0 assignment
**How Ellen Solved It:** Reversed priority in Runtime::Result::_command_name() to check $0 FIRST (current script path), only using $ENV{DEVELOPER_DASHBOARD_COMMAND} as a final fallback; added special case for 'run' basename which checks parent directory (for directory-backed commands); verified that reversing priority doesn't break hook execution behavior
**How To Detect Earlier Next Time:** When a test failure shows command name mismatch or stale state from previous tests: (1) check if environment variables were modified by earlier tests and not cleaned up, (2) check if priority order in name derivation is correct (actual script source should come before env var), (3) use tempdir-based HOME override in all tests to prevent env var pollution across test boundaries, (4) use local %ENV or localenv blocks to prevent env var leakage between tests
**Prevention Rule:** Any global state (especially environment variables) that affects runtime behavior must be cleared between test cases or explicitly isolated with tempdir/override; when deriving runtime state from multiple sources (env var, $0, parent directory), prioritize the most current/reliable source first, not the environment variables which can persist across hook execution boundaries
**Related Work:**
  1. Phase 1: Fixed macOS test 14 failure
  2. Phase 6: Renamed all project modules to Developer::Dashboard::* namespace
  3. Phase 3: Renamed CLI subcommands (pjq→jq, etc.) to prevent PATH pollution
  4. Phase 8: Implemented isolated skill system with Git-backed installation
  5. Phase 11: Implemented /skill/:repo/:route namespacing for app integration
**Completed in v1.47:**
  - ✅ Runtime::Result::_command_name() reversed priority logic
  - ✅ Tests 155-156 now pass (equivalent to original test 14)
  - ✅ All 214 core smoke tests pass without skips
  - ✅ 41 new tests added (33 skill system + 8 web routes)
  - ✅ 5 core modules migrated to Developer::Dashboard::* with backward-compatible facades
  - ✅ 4 CLI subcommands renamed (pjq→jq, pyq→yq, ptomq→tomq, pjp→propq)
  - ✅ 3 new query subcommands added (iniq, csvq, xmlq)
  - ✅ dist.ini exclude_match prevents generic commands from polluting system PATH
  - ✅ Makefile.PL post-install hook extracts private CLI tools to ~/.developer-dashboard/cli/
  - ✅ Full skill system implemented: install, uninstall, update, list, dispatch
  - ✅ Skill isolation guaranteed: ~/.developer-dashboard/skills/<repo-name>/
  - ✅ Skill app route namespacing: /skill/:repo-name/:route pattern
  - ✅ Full documentation: Changes, FIXED_BUGS, README, POD all updated
  - ✅ Version consistency: all modules at v1.47
**Verification:**
  - `perl -I lib t/05-cli-smoke.t` returns 214/214 tests passing
  - `perl -I lib t/19-skill-system.t` returns 33/33 tests passing
  - `perl -I lib t/20-skill-web-routes.t` returns 8/8 tests passing
  - Total: 255/255 tests passing (214 core + 41 new)
  - No test failures, no test skips
  - Full backward compatibility verified
  - Git history: 8 meaningful commits with Co-authored-by trailers

## CODE: DIST-SOURCE-ASSUMPTION

**Date:** 2026-04-04 10:30:00 UTC
**Area:** Tarball packaging verification and release metadata tests
**Symptom:** Blank-environment `cpanm` install failed even though the checkout passed locally; the built distribution died in `t/15-release-metadata.t` because the test assumed source-tree files and cwd semantics that do not hold inside the extracted tarball.
**Why It Was Dangerous:** It created a false release-ready signal in the checkout while the actual shipped artifact was not installable through `cpanm`, which is the real delivery path for this project.
**Root Cause:** The metadata test treated the source tree and built distribution as identical. It read `dist.ini`, assumed relative cwd access to repo files, and checked generated `Makefile.PL` for a private-helper staging detail that is actually expressed by shipped `private-cli/` assets, not installer code.
**How Ellen Solved It:** Reworked the release metadata test to resolve paths from the test file location, use shipped artifacts only, fall back to `META.json` when `dist.ini` is not present in the built dist, and assert the packaged `private-cli/*` assets directly instead of expecting generated installer text to mention them.
**Prevention Rule:** Any release or packaging test must validate the built tarball as shipped, not the source checkout by accident. If a file is not guaranteed to exist in the dist, the test must use a shipped equivalent or skip that assertion in the built artifact path.
